-**The fastest and most efficient code intelligence engine for AI coding agents.** Full-indexes an average repository in milliseconds, the Linux kernel (28M LOC, 75K files) in 3 minutes. Answers structural queries in under 1ms. Ships as a native executable with a small verified runtime-asset set for macOS, Linux, and Windows — download, run `install`, done.
+**Search your code, follow call graphs, and explore software architecture in your browser.** codebase-memory-mcp is a local [Model Context Protocol](https://modelcontextprotocol.io/) (MCP) server that gives Claude Code, Codex, and other coding agents a persistent code knowledge graph. It indexes functions, classes, imports, HTTP routes, and their relationships across [162 languages](#language-support). [Hybrid LSP](#hybrid-lsp) adds semantic type resolution for **Python, TypeScript, JavaScript, JSX/TSX, PHP, C#, Go, C, C++, Java, Kotlin, Rust, and Perl**.
 
-High-quality parsing through [tree-sitter](https://tree-sitter.github.io/tree-sitter/) AST analysis across all 162 languages, enhanced with [**Hybrid LSP** semantic type resolution](#hybrid-lsp) for Python, TypeScript / JavaScript / JSX / TSX, PHP, C#, Go, C, C++, Java, Kotlin, Rust, and Perl — producing a persistent knowledge graph of functions, classes, call chains, HTTP routes, and cross-service links. 17 MCP tools. No language runtime, hosted service, or API key. Plug and play across 45 supported automatic/conditional client surfaces.
+**About 120× fewer tokens** in the project's reported five-query comparison: ~3,400 vs ~412,000 with file-by-file exploration. Published backend benchmarks also report **Linux kernel indexing in ~3 minutes** (28M lines of code) and **Cypher relationship queries under 1 ms** on an Apple M3 Pro. [Benchmark details](#performance).
 
-> **Research** — The design and benchmarks behind this project are described in the preprint [*Codebase-Memory: Tree-Sitter-Based Knowledge Graphs for LLM Code Exploration via MCP*](https://arxiv.org/abs/2603.27277) (arXiv:2603.27277). Evaluated across 31 real-world repositories: 83% answer quality, 10× fewer tokens, 2.1× fewer tool calls vs. file-by-file exploration.
+**CBM Lens Beta helps you understand unfamiliar code and stay in control as it grows.** Use it to get up to speed in a new codebase, tackle rescue engineering on an inherited project, or make sense of 50,000 lines of AI-generated code from a single day. Its IDE-style source reader, local code chat, 3D architecture map, and Galaxy graph let you see how the code fits together and follow dependencies and call paths back to the source. Use that context to review changes, investigate fragile areas, and keep code quality high. Architecture decisions stay alongside the project's index.
 
-> **Security & Trust** — This tool reads your codebase and writes to your agent configuration files. That is what it is designed to do. If you prefer to audit before running, the [full source is here](https://github.com/DeusData/codebase-memory-mcp). For each release product, three behaviourally identical executable candidates (unstripped, debug-stripped, stripped) are submitted to VirusTotal before testing; the selected candidate is then packaged with its SHA-256 unchanged. Release notes link every measured candidate result. Publication permits only the narrowly documented single-Microsoft `!ml` tolerance in [SECURITY.md](SECURITY.md#our-release-policy). All processing happens 100% locally; your code never leaves your machine. Found a security issue? We want to know — see [SECURITY.md](SECURITY.md). Security is Priority #1 for us.
+The native C backend exposes 17 MCP tools and supports 45 automatic or conditional client integrations. Indexing and graph queries need no hosted service or API key.
+
+> **CBM Lens Beta is new on `main`:** it arrived with [PR #2068](https://github.com/DeusData/codebase-memory-mcp/pull/2068) and is not part of the current v0.11.0 release, whose installer still ships the previous graph UI. To run the interface shown below now, [build from source](#build-from-source).

+
+> **Research:** The [preprint](https://arxiv.org/abs/2603.27277) compares agents across 31 repositories, reporting **10× lower token use** and **2.1× fewer tool calls**, with answer-quality scores of 83% for CBM versus 92% for file-by-file exploration. These backend results are separate from the five-query comparison above and from CBM Lens.
+
+> **Local processing:** Source analysis and graph storage run on your machine. CBM Lens can optionally download a model for browser AI after you enable it; inference stays on the device. The installer writes agent configuration for the clients you select. See [Security](#security) for release verification and [SECURITY.md](SECURITY.md) for reporting issues.

+**Architecture overview.** Folders become nested platforms, files and symbols become selectable blocks, and arrows show indexed relationships. The recording zooms into the map of this repository, selects `src/pipeline`, opens the area, selects `artifact.c` and opens its source. Height can show source size; hotspot gravity reflects static fan-in. [Still image](docs/images/lens-architecture.png).

 ## Why codebase-memory-mcp
 
-- **Extreme indexing speed** — Linux kernel (28M LOC, 75K files) in 3 minutes. RAM-first pipeline: LZ4 compression, in-memory SQLite, fused Aho-Corasick pattern matching. Memory released after indexing.
-- **Plug and play** — native executable plus authenticated release-owned assets for macOS (arm64/amd64), Linux (arm64/amd64), and Windows (amd64). The native install needs no Docker, language runtime, or API keys. Download → `install` → restart agent → done.
-- **162 languages** — vendored tree-sitter grammars compiled into the binary. Nothing to install, nothing that breaks.
-- **120x fewer tokens** — 5 structural queries: ~3,400 tokens vs ~412,000 via file-by-file search. One graph query replaces dozens of grep/read cycles.
-- **45 supported automatic/conditional client surfaces** — `install` configures detected clients and safely activates conditional clients only when their documented platform, marker, or explicit existing config path is present. See [Multi-Agent Support](#multi-agent-support) for the complete matrix and manual/UI-only boundaries.
-- **Built-in graph visualization** — 3D interactive UI at `localhost:9749`, served from the binary itself.
-- **Infrastructure-as-code indexing** — Dockerfiles, Kubernetes manifests, and Kustomize overlays indexed as graph nodes with cross-references. `Resource` nodes for K8s kinds, `Module` nodes for Kustomize overlays with `IMPORTS` edges to referenced resources.
-- **17 MCP tools** — search, trace, architecture, impact analysis, targeted index-coverage checks, Cypher queries, dead code detection, cross-service HTTP linking, ADR management, and more.

-CBM automatically shares one per-account coordination daemon across Claude Code, Codex, OpenCode, and every other configured client. There is no opt-in setting for MCP servers or hook clients: the first daemon-backed CBM session starts it, each session registers its own work, and the final session shuts it down. The daemon owns long-lived background services such as watchers, shared indexing jobs, and the optional UI. Closing one session cancels work owned only by that session, while work still needed by another session continues.

Closing one session cancels work owned only by that session, while work still needed by another session continues.

 The native `install`, `update`, and `uninstall` commands are the deliberate exception to that conflict rule. Download, verification, and private same-filesystem staging happen first so a bad candidate never disrupts active work. Activation then publishes account-wide maintenance intent, asks the daemon and every temporary local operation to cancel, and waits to a finite deadline for all coordinated CBM processes to exit. It holds the admission and lifetime barriers exclusively while changing the active binary, configuration, PATH, or indexes. New CBM work cannot enter during this window. Activation progress and results are recorded in `${CBM_CACHE_DIR}/logs/activation-events.ndjson`, and a successful command tells you to restart open coding-agent sessions so they launch the activated build.

-The graph UI is built into the binary — every install on every channel has it. Then run it:
+CBM Lens Beta is the browser interface built into the binary. It builds on [CodeAtlasWeb](graph-ui/README.md) by [Bernhard Jackiewicz](https://github.com/BernhardJackiewicz) (design and tracking in #1964). It runs on loopback; the only request that leaves your machine is the optional model download from Hugging Face, and only after you start it. Each panel names where its facts come from, and what the index did not record is shown as a gap. Start the local server:
 
 ```bash
-codebase-memory-mcp --ui=true --port=9749
+./build/c/codebase-memory-mcp daemon start --open --port=9749
 ```
 
-Open `http://localhost:9749` in your browser. The UI is owned by the shared coordination daemon, so concurrent agent sessions do not start duplicate HTTP servers.
+The browser opens at `http://127.0.0.1:9749`. A permanent daemon keeps the UI available after the command exits. Use `daemon status` to inspect it and `daemon stop` when you are finished. For an MCP session, `--ui=true --port=9749` enables the same shared UI. Active clients must use the same executable build and cache directory.
+
+**Open your first repository**
+
+1. Open the project menu and choose **Add project index**. You can also use `Alt+P`.
+2. Choose a local repository folder and name the index. Files stay in place.
+3. Start indexing and follow its reported status. You can close the dialog while it runs and reopen its activity from the project menu.
+4. Open the indexed project. Start with Architecture for an overview or Explore to read a file.
+
+To bookmark a view, use `?project=<name>&workspace=architecture`. Other workspace values are `explore`, `galaxy`, `adr`, `coverage`, and `system`.
+
+| Workspace | What you can do |
+|-----------|-----------------|
+| **Explore** | Navigate the indexed file tree and read source in Monaco. File impact shows what depends on the open file; Code details shows the callers, calls, references and related tests of the symbol under the caret. |
+| **Galaxy** | Search and focus graph nodes, load their neighbors layer by layer, switch to hierarchy, follow a path, and open source. Back and Forward return to earlier views. The coverage shadow marks known gaps around the loaded graph. |
+| **Architecture** | Explore the folder map, entry points, routes, hotspots, system structure, and behavior paths. Select a node or connection to inspect its evidence. |
+| **ADR** | Read and edit the project's architecture decision record. Save explicitly; the document is stored with the index and shared with `manage_adr`. |
+| **Coverage** | Check indexed, partially parsed, skipped, and excluded paths, together with available freshness information. |
+| **System** | Inspect daemon activity, indexes, and logs. Filter logs by project, severity, or text. |
+
+**Architecture views**
+
+- **Overview:** move through source folders and files on a 3D map. Choose source-size or uniform height, language or kind colors, and relationship filters. Switch to Entry points to follow a static call graph from a starting symbol.
+- **Routes:** switch between the service map and endpoint connections. Deployment metadata and indexed route evidence are shown separately; unresolved registrations remain visible.
+- **Hotspots:** inspect symbols using measured signals such as fan-in and complexity. Gravity wells help locate frequently referenced areas. They are not a code-quality score.
+- **System structure:** inspect component dependencies, expand groups, isolate cycles, and follow connections back to source evidence.
+- **Behavior:** choose a source and a reachable destination to inspect static call paths and their source statements. These paths show possible relationships, not a recorded execution order. Runtime observations require separately ingested traces.
+
+Drag a 3D view to orbit, scroll to zoom, and select a node or edge to inspect it. Edge colors distinguish relationships, and pulses indicate their direction. Reduced-motion preferences pause the pulses. Large views show their limits and omitted counts. A missing edge can reflect an indexing or display limit, so check Coverage and the source before drawing conclusions.
+
+#### Chat with your codebase locally
+
+Open **Chat** with the panel button at the top right to ask about the code you are looking at. In Explore it uses the open file or the exact text you have selected; in Galaxy it uses the selected node and its loaded neighbors. You can also attach graph evidence through **Add context**.
+
+1. Click the robot icon at the top right to open the agent configuration.
+2. Choose a local model. The default Qwen2.5 Coder 0.5B downloads about 567 MB; Qwen3 0.6B, LFM2.5 1.2B and Qwen3.5 2B are larger options. All need WebGPU with `shader-f16` support.
+3. Click **Download & load**. Model files come from Hugging Face; inference runs in your browser, with no hosted chat API or API key. A model that is already in the browser cache loads with **Load model (cached, no download)**.
+4. Ask a question. The composer shows the file or selection that will accompany it. Select a smaller range when you want to focus the answer.
+
+Questions about callers and callees, such as "Who calls cbm_pipeline_run?", are answered from the loaded graph without the model, and the answer says so. When you select a symbol, the chat lists its indexed facts and the lines of its code, and the model adds one sentence; that sentence is left out when it claims something the source does not show. Text written by the model is labelled as such.
+
+The recording shows a question about callers answered from the indexed graph, next to the automatic explanation of the selected symbol. [Still image](docs/images/lens-chat.png).
+
+<p align="center"><img src="docs/images/lens-chat.gif" alt="Chat with your codebase locally in CBM Lens Beta: a selected symbol, its listed facts and a caller question answered from the indexed graph" width="1000"></p>
+
+The chat history is kept for 24 hours in this browser, per project. Each new message uses the source currently open in the reader; earlier source snapshots are not silently accumulated, and messages about another file or selection are not sent along. If a prompt is too long for the model, older messages are left out first; if it still does not fit, CBM Lens asks you to select less code instead of cutting the code. This chat explains the context you give it; it cannot edit files or run tools. Check its answers against the source. The small default model words things loosely, especially in languages other than English.
+
+#### Search
+
+`Cmd+K` or `Ctrl+K` opens the Galaxy search. It finds symbols, files and folders by name or path in the whole index, also nodes that are not loaded yet. For callers and callees, ask in the chat; the answer is listed from the graph.
+
+**Architecture decisions**
+
+The ADR workspace keeps an unsaved draft per project in this browser tab. It checks whether the stored document changed before saving, but the API does not provide an atomic document lock. The editor accepts up to 8,000 UTF-8 bytes. Saving changes the indexed decision document, not a file in your repository.
+
+<details>
+<summary>Experimental agent activity</summary>
+
+The Agents workspace and activity overlays are hidden in normal builds. To include them in a source build:
+
+```bash
+VITE_EXPERIMENTAL_AGENTS=true scripts/build.sh --with-ui
+```
+
+Activity comes from explicitly configured tool hooks. The bundled adapter supports Claude Code PostToolUse; other clients need their own adapter. Recorded events go to the local daemon, and the reader must enable activity before the browser polls them. This does not automatically observe every agent. See the [frontend setup guide](graph-ui/README.md#die-agentenebene-was-live-arbeitende-agenten-auf-dem-graphen-zeigen).
+
+</details>
+
+For troubleshooting, open System logs. Frontend errors and failed requests are recorded locally. `GET /api/ui-log` reads frontend entries from the daemon's SQLite journal; `${CBM_CACHE_DIR}/logs/ui.log` is also retained as a rotating JSONL export. See the [frontend README](graph-ui/README.md) for log scope, model setup, and development details.

+The watcher follows MCP sessions: it watches the project each open MCP session is rooted in (the client's working directory) and stops when the last session for that project closes. A repository indexed with `cli index_repository`, or indexed from a session rooted somewhere else, is not watched; re-run `index_repository` after changing it. `index_status` reports this in its `watch` object: `watched`, and either the poll cadence and last scan time or the `reason` it is not watched.

+- **Architecture overview**: `get_architecture` returns a compact summary by default. Request specific `aspects` for routes, hotspots, dependencies, clusters, or cycles. `system_structure` provides the projection used by CBM Lens and must be requested on its own.
 - **Architecture Decision Records**: `manage_adr` persists architectural decisions across sessions
 - **Louvain community detection**: Discovers functional modules by clustering call edges
 - **Git diff impact mapping**: `detect_changes` maps uncommitted changes to affected symbols with risk classification
 - **Call graph**: Resolves function calls across files and packages (import-aware, type-inferred)
-- **Dead code detection**: Finds functions with zero callers, excluding entry points
+- **Dead code candidates**: find functions with no indexed callers, excluding entry points. Check dynamic dispatch, coverage gaps, and framework conventions before removing code.
 - **Cypher-like queries**: `MATCH (f:Function)-[:CALLS]->(g) WHERE f.name = 'main' RETURN g.name`
 
 ### Search

-- **Multi-galaxy 3D UI layout** for cross-repo architecture visualization
 - **Cross-repo architecture summary** combining services, routes, and dependencies across the indexed fleet
+- **Run status**: `index_status` (and the UI layout next to `linked_projects`) carries a `cross_repo` object, `{"status":"never_run"}` until `index_repository(mode="cross-repo-intelligence")` has run with that project as the source, then `"ran"` with `last_run_at`, `outcome`, `targets`, `projects_scanned`, `total_cross_edges` and `skipped_projects`. That is how you tell "never linked" apart from "linked, nothing matched". The status is stored in the project's own index next to its `CROSS_*` edges, so a reindex that rebuilds the index drops both at once and the status goes back to `never_run`.
+- **Skipped stores**: `target_projects: ["*"]` skips an index built before the #768 schema change rather than failing the whole run. The response lists each one as `skipped_projects: [{"name", "reason": "pre_768_schema", "hint": "reindex this project"}]`.

+- `HTTP_CALLS`, `ASYNC_CALLS` (cross-service); a shell script, Make recipe or CI step running `curl` / `wget` on a URL it states (constant words resolved, unknown parts `{}`) to its `Route` with the method its flags give: a Kubernetes Service of the repository by the path, as code clients do, any other host (a download, localhost) with the host kept; the edge keeps `via`, `method`, `url_path`, `host`, never the user info or the query
+- `SPAWNS`: the caller starts another program (`subprocess.run`, `exec.Command`, `posix_spawn`, `Process.Start`, a shell command or Make recipe running a program by path, ...); the target is a `Process` node named after the program, or `<dynamic>` when the program is not a literal. When a shell script, Make recipe, GitHub Actions step or Prow job runs a script of the repository (`./hack/x.sh`, `bash hack/x.sh`), the target is that script's `Module` (else its `File`); `make TARGET` (also `$(MAKE)`, `-C`, `-f`) targets the rule of that target, followed through included makefiles; edges from CI carry `ci` and `job`. A Dockerfile's last stage `ENTRYPOINT` (else `CMD`) spawns what the container runs (`api: dockerfile`): the repository script or source copied into the image, the Go `main` of a binary a stage builds with `go build -o`, else a `Process`
+- `INFRA_MAPS`: a Kubernetes Service to each workload whose pod labels carry every `key: value` of the Service's selector, within one namespace
+- `CONNECTS_TO`: a Kubernetes workload or compose service to the Service its containers' environment addresses (`PRODUCT_CATALOG_SERVICE_ADDR: productcatalogservice:3550`, a URL's host, `<svc>.<ns>.svc...`, a bare name on an `*_ADDR` / `*_HOST` / `*_URL` / ... key; compose: the project's `.env` interpolated): a Kubernetes Service of the same bundle and namespace, or a compose service of the same file. The edge keeps `via: env`, `key` and `container`, never the value
+- `USAGE` with `ref: image`: a Kubernetes workload (any pod template: containers, initContainers, CronJobs, custom resources) or a docker compose service to the `Image` it runs
+- `DEPLOYS`: what puts manifests, kustomizations or charts on a cluster, to what it puts there: a Flux Kustomization or Argo Application to the kustomizations / manifests / chart of its path, a Flux HelmRelease to its chart (`spec.chart` or `chartRef` → OCIRepository), a shell command or Make recipe (`kubectl apply -f/-k`, `kustomize build | kubectl apply`, `helm install/upgrade/template`), a Go installer loading a chart with the Helm SDK, a Terraform `helm_release`, a Terraform `kubernetes_*` resource the object it declares (a `Resource` like a manifest's, `ecosystem: terraform`, when its name is a literal), a kustomization inflating a chart (`helmCharts`; its values file an `IMPORTS`). A chart outside the repository is an external `Chart`, keyed by its publisher when its repository URL is stated (`__chart__<repository>/<name>`, the same node in every project, the URL in `repository`), else one per project and name; the edge says `via` (`flux`, `argo`, `helmrelease`, `kubectl`, `kustomize`, `helm`, `helm-sdk`, `terraform`, `helmcharts`, ...)
+- `DEPENDS_ON`: a Helm chart to the charts it declares (the local chart for a resolvable `file://` repository, otherwise an external `Chart`; the edge keeps `repository`), and a `go.mod` / `requirements.txt` file to an external `Package`; a Dockerfile to the `Image`s it builds on (`via: from`, `copy-from`); an `Image` to the Dockerfile it is built from (`via: build`; `tool`: `skaffold`, `compose`, `docker-build` for `docker` / `podman` / `nerdctl` / `buildah` build commands in scripts, Make and CI); a compose service to the services its `depends_on` / `links` name
+- `CONFIGURES`: code reading an environment variable to the shared `EnvVar` of that name (`strategy: env_access`); a Kubernetes container, compose service or Dockerfile (`ENV` of the image) setting one to that container's own `EnvVar` (`strategy: env_set`, with `source`: `value`, `configMapKeyRef`, `secretKeyRef`, `fieldRef`, ..., `compose`, `dockerfile`; values are never stored); and that container's `EnvVar` to the code reading the name inside the files its image is built from (`strategy: env_read`, with `dockerfile`): the image's files are the sources its Dockerfile's `COPY` / `ADD` put into it, less the context's `.dockerignore`
+- `CONFIGURES` with `strategy: key_symbol`: a code symbol to the config key it names (`config_key`). A YAML, JSON, HCL (Terraform, OpenTofu, tfvars), TOML or INI key links by exact name (`maxRetryCount` = `max_retry_count`) and only to code inside the config file's component: its directory, or the one around a `config/`, `configs/`, `conf/`, `settings/` or `etc/` directory. A `.env` or `.properties` key also links by substring (confidence 0.75)
+- `OVERRIDE` with `via: patch`: a Kustomize patch to each object of its kustomization's build it changes (child → base): a patch file's documents to the object of the same kind and name; an inline patch (from the kustomization) or a JSON6902 operation file to what its `target` selects (group, version, kind, name, namespace, label selector); a component's in the build of each kustomization including it. The edge keeps `kustomization`, `patch` and `line`; a patch file is an `IMPORTS` (`local_name: patches`) of its kustomization, never a member of the build
+- `OVERRIDE` with `via: namePrefix` / `nameSuffix`: an object a kustomization renames, from its variant: a `Resource` named with the deployed name (`capi-` + `controller-manager`; the prefixes of nested kustomizations outermost first, suffixes innermost first) in the namespace that build gives it, `ecosystem: kustomize`, which the kustomization's file `DEFINES`. CRDs, Namespaces and API services keep their names, as kustomize does. The edge keeps `kustomization` and `line`
+- `USAGE` with `via: terraform`: a Terraform / OpenTofu reference (`var.X`, `local.X`, `module.X`, `data.T.N`, `T.N`) from the top-level block holding it to the block of its module (the `.tf` / `.tofu` files of its directory) that declares it (a `locals` entry: its `locals` block); an entry of the block's `depends_on` list is a `DEPENDS_ON` instead. The edge keeps `ref` (`var`, `local`, `module`, `data`, `resource`) and `line`; a name only mentioned in string text is no reference. A module call with a local source (`module "net" { source = "./modules/net" }`) `IMPORTS` (`local_name`: the module's name) the `Folder` of that directory (the root directory: the `Project`), and `module.net.id` (also `module.net[0].id`, `module.net[*].id`) `USAGE`s (`ref: output`) the `output "id"` there, beside `module.net`
+- `OVERRIDE` with `via: tfvars`: a `.tfvars` assignment to a variable the module of its own directory declares, from the file's `Variable` to that `variable` block (the edge keeps `line`); a `.tfvars` file whose own directory declares none of its names sets the nearest ancestor module's that does, the edge marked `inferred` (such a file is applied by a `-var-file` the repository does not state)
+- Terragrunt (`via: terragrunt`): a unit (`terragrunt.hcl`), evaluated in its own context: an `include` `IMPORTS` (`local_name`) the file its `path` names; a `read_terragrunt_config` `IMPORTS` (`read`: the file holding the call) the file it names, from the block holding the call or, for a call in an included file, from the unit's `include` block that brings it in; a `dependency` `DEPENDS_ON` the other unit; a local `terraform` `source` `IMPORTS` its `Folder`. Paths may use `find_in_parent_folders`, `dirname` and `get_terragrunt_dir`; anything else is unknown and links nothing
+- Ansible (`via: ansible`): a playbook or task file (a YAML file whose top level is a sequence) `IMPORTS` (`local_name`: the directive) what its directives name: `import_playbook` a playbook, `include_tasks` / `import_tasks` / `include` a task file (from its directory, else its role's `tasks/`), `roles:` items and `include_role` / `import_role` a role's `Folder` (`roles/<name>` at or above its directory).

 ## Troubleshooting & Diagnostics
 
-codebase-memory-mcp runs **100% locally and collects no telemetry** — your code, queries, environment, and usage never leave your machine. That privacy guarantee also means that when you hit something we can't reproduce on our side (a slow memory climb over hours, a performance regression, a leak that only appears after days of real use), **we have no data at all unless you choose to send it.** Here is how to capture it yourself.

 ### Capture a diagnostics log
 
-Set `CBM_DIAGNOSTICS=1` before the first daemon-backed MCP session starts, then reproduce the problem (let it run as long as it takes — a slow leak needs time to show in the trend). The shared daemon captures this setting from the session that starts it. If it is already running, close all daemon-backed sessions so it exits before changing the setting. The daemon creates a fresh owner-private `cbm-diagnostics-<pid>-<random>` directory below the system temp directory (`$TMPDIR` or `/tmp` on macOS/Linux, `%TEMP%` on Windows). The exact paths are recorded by the `diagnostics.start` event in `${CBM_CACHE_DIR}/logs/cbm-daemon.log`:

It is **kept on disk after the server exits** (so you can grab it post-mortem) and rotates to `trajectory.ndjson.1` past ~8 MB. |
-| `snapshot.json` | The latest snapshot only — handy for a quick live check. Removed on clean exit. |

 The private randomized directory prevents another local account from pre-placing a link or special file at a predictable diagnostics path. Its `<pid>` component is the shared daemon's process ID, also recorded by the `daemon.start` event. Set the variable consistently in the `env` block of each agent's MCP server config, or export it before launching the first session.
 
 ### What to share
 
-When you open a memory/performance issue, **attach the `.ndjson` trajectory** — it contains no source code or query text, only resource counters. If you'd rather not attach a file, paste it (or an agent's summary of it) into the issue: your assistant can read the NDJSON directly and report whether `rss`/`committed` grow monotonically, how fast, and relative to query count — which is exactly what we need to find the cause.

 | `CBM_DIAGNOSTICS` | `false` | Set to `1` or `true` to enable the shared daemon's periodic `snapshot.json` and retained `trajectory.ndjson` below a fresh owner-private directory in the system temp directory. Exact paths are logged by `diagnostics.start`. |
 | `CBM_DOWNLOAD_URL` | *(GitHub releases)* | Override the download URL for updates. Used for testing or self-hosted deployments. |
-| `CBM_LOG_LEVEL` | role-aware | Set the minimum log level. Thin MCP/CLI/hook frontends default to `warn`; the detached daemon and its supervised index workers default to `info` so lifecycle and liveness records remain available. Accepted values (case-insensitive): `debug`, `info`, `warn`, `error`, `none` — or their numeric equivalents `0`–`4`. A physical worker retains INFO liveness records even under a stricter override because its private log drives the supervisor's no-progress timeout. Frontend messages go to that session's stderr; detached daemon events go to `${CBM_CACHE_DIR}/logs/cbm-daemon.log`. Stdout is reserved for MCP JSON-RPC. |
-| `CBM_WORKERS` | *(detected)* | Override the parallel-indexing worker count returned by `cbm_default_worker_count`. Useful inside containers where `sysconf(_SC_NPROCESSORS_ONLN)` reports host CPUs rather than the cgroup's effective quota. Range 1–256; invalid values are ignored with a warning. |

Useful on bare-metal hosts without a cgroup limit, or to pin a budget *below* the cgroup limit so headroom is left for sibling processes.

No language server process, no per-project setup, no API key. We call this layer **Hybrid LSP**: it runs alongside tree-sitter on every parse and refines invocation resolution (`CALLS` / `RESOLVED_CALLS`) and callable-value resolution (`CALL_REFERENCE`, with ambiguous values retained as `USAGE`) using type information, so the resulting graph mirrors what an IDE "Go to Definition" would resolve.

Off stores no candidates and leaves the rest of the graph unchanged; on in `fast` mode stores candidates without adding `fast`'s skipped `SIMILAR_TO` / `SEMANTICALLY_RELATED` edges. `index_repository` also takes `doc_candidates` for a single index, which wins over this setting.

+### Shared / HPC filesystems
+
+On clusters and other shared machines, home directories often live on a network
+filesystem (NFS, Lustre, GPFS, SMB/CIFS), and `~/.cache` is sometimes a symlink
+into a shared tree. Three rules keep CBM working there:
+
+- **Put the cache and the rendezvous on local storage.** Set `CBM_CACHE_DIR` (indexes,
+  `_config.db`) and, if needed, `CBM_RUNTIME_DIR` (the daemon rendezvous) to a
+  local disk you own, for example `/local/scratch/$USER/cbm` or `/tmp/$USER-cbm`.
+  Set the same values in your MCP client's environment and your shell.
+- **Do not route the cache into another account's tree.** A symlinked `~/.cache` is
+  resolved and allowed, but every directory on the *resolved* path must be owned
+  by you or by root. If a parent such as `/shared/fs` belongs to another account,
+  that account can rename or replace anything below it, so CBM refuses the path
+  and names the directory and its owner:
+
+  ```text
+  ... (cache-private) - '/shared/fs' is owned by uid 1234 (alice), not by you (uid 1000) or root; ...
+  ```
+
+  This check has no override. Choose a location with a safe ancestry instead.
+- **Avoid network filesystems for the cache.** The indexes are SQLite databases in
+  WAL mode, which needs shared-memory locking that network filesystems do not
+  provide reliably. On Linux, CBM logs one `daemon.cache_root_network_fs` warning
+  at startup when the cache root is on NFS, Lustre, GPFS, CIFS or SMB2. The cache
+  still works there, but it can be slow, and a database can be corrupted.

+# Smart CI: pull-request test selection on GitHub Actions
+
+Smart CI runs, for each pull request, only the CI jobs and tests that the
+change can reach. This page explains how this repository does it and how
+another repository on GitHub Actions could do the same with the released
+`codebase-memory-mcp` binary.
+
+Status: experimental. Every answer carries `"experimental": true`. The
+selection narrows real test runs only while the repository variable
+`TEST_IMPACT_MODE` is `gate`; otherwise it runs in report-only (shadow) mode.
+
+> **Read the scope section before you start.** The lane layer is a pattern
+> any repository can copy. The test layer narrows only C/C++ code whose tests
+> follow this repository's test-framework conventions (or declared
+> equivalents), and only with a per-test coverage map that you must produce
+> yourself. In any other repository the engine answers "run everything". That
+> is safe, but it saves nothing.
+
+## The guarantee
+
+Smart CI never runs fewer tests unless it can show that the omitted tests
+cannot be affected. When it is unsure, it runs everything:
+
+- a path that no rule knows, an empty or truncated file list, or a change to
+  the selection's own configuration, tooling or workflows;
+- a shallow clone, a diff that cannot be read in full, or an invalid config;
+- no coverage map, or a coverage map that is not admitted (wrong commit, more
+  than 7 days old, made for another platform or harness);
+- a change that reaches the test runner's `main`, or a test-runner role
+  (below) that no test names;
+- a role table entry the engine cannot read, or a macro naming a role's
+  literal that it cannot follow;
+- any failure of the selection job itself.
+
+Each of these makes the run cost more CI minutes. None of them loses coverage.
+

+
+| | Layer 1: lanes | Layer 2: tests |
+|---|---|---|
+| Question | Which jobs (lint, test legs, smoke, sanitizers) does this PR need? | Inside a test job, which suites and tests? |
+| Input | The PR's changed-file list | Git history, the code graph, a per-test coverage map |
+| Implementation | `scripts/ci/select-lanes.sh` (repository-specific rules) | The binary's `test-impact select` subcommand |
+| Unknown input | Every lane runs | Every test runs (`run_all` with reasons) |
+| Portable? | As a pattern: you write your own rules | C/C++ with supported test conventions only (see below) |
+
+## Can your repository use it?
+
+| Piece | General? | What you provide |
+|---|---|---|
+| Lane selection (Layer 1) | Pattern only | Your own path → category → lanes rules. `select-lanes.sh` encodes this repository's paths. |
+| Engine (`test-impact select`) | Ships in the binary | Nothing to build. |
+| Source languages it can narrow | **C family only**: `.c .h .cc .cpp .hpp .m .mm .cxx .hh` | Every other changed file must match a config rule (`ignore`, `referencing_tests`, ...). Otherwise the answer is `run_all` (`UNMAPPED_FILE`). |
+| Test model | **C family only** | The `c-cbm` preset (this repository's `TEST`/`SUITE`/`RUN_TEST`/`RUN_SELECTED_SUITE` macros, see `tests/test_framework.h`), or custom `tests.conventions` records for equivalent C macros. |
+| Coverage map | **Required to narrow at all** | Format-1 files (`functions.tsv`, `tests.tsv`, `meta.json`). This repository produces them with an LLVM-instrumented runner and `scripts/test-impact/coverage-map.py`, which are both specific to its harness. |
+| Runner filter | Pattern | A test runner that can run a `suite` / `suite:test` list and fails when a listed test does not exist. |
+
+The other presets (`pytest`, `go`, `junit`, `gtest`, `rust`, `jest`) are
+accepted switches, but the engine does not model them. An enabled `gtest`
+blocks narrowing for C++ files. Custom `tests.conventions` are covered by the
+model's unit tests. The engine's end-to-end tests use `c-cbm` only. Treat
+custom conventions as unproven until you have shadow evidence.
+
+Without admitted coverage the engine marks every suite `whole`, and the lane
+reports `run_all`. Static reachability alone never omits a suite.
+
+## Prerequisites
+
+1. **The binary, pinned.** Use the same release in the producer and the PR
+   jobs. Download that release's Linux archive and verify it against the
+   release's `checksums.txt`, as this repository's shadow job does
+   (`scripts/ci/test-impact-shadow.sh --fetch-release`):
+
+   ```bash
+   CBM_VERSION=vX.Y.Z   # a release that contains the features you use (see below)
+   asset=codebase-memory-mcp-linux-amd64.tar.gz
+   gh release download "$CBM_VERSION" --repo DeusData/codebase-memory-mcp \
+     --pattern "$asset" --pattern checksums.txt --dir "$RUNNER_TEMP/cbm"
+   (cd "$RUNNER_TEMP/cbm" && grep " $asset\$" checksums.txt | sha256sum -c - &&
+     tar -xzf "$asset" codebase-memory-mcp)
+   "$RUNNER_TEMP/cbm/codebase-memory-mcp" --version
+   ```
+
+   For a quick start, `install.sh` installs the latest release with the same
+   checks (HTTPS only, SHA-256 against `checksums.txt`, the archive's member
+   list, `--version`); `--skip-config` skips agent configuration, which a CI
+   runner does not need. It has no version flag, so it is not a pin.
+
+   **Version note.** `v0.12.0` and `v0.12.1` have `test-impact select`/`publish`.
+   They do not have `key: "path"`, `unreferenced`, `--vetoed-out` or
+   `run_all_rules`; those ship in a later release. With either version, a config
+   that uses those keys is invalid, and every answer is `run_all`. Until that
+   release, build the binary from source (`make -f Makefile.cbm cbm`), as this
+   repository's producer and `select-tests` jobs do.
+
+2. **Full git history.** Check out with `fetch-depth: 0` in every job that
+   runs the engine. The engine verifies the history it diffs and refuses a
+   shallow clone (`GIT_UNAVAILABLE`, everything runs).
+
+3. **A runner that runs a named subset.** See "The test job" below.
+
+4. **A coverage producer on the default branch** that writes the format-1 map
+   for every test, child processes included. A test whose coverage is
+   uncertain must be marked `incomplete`. An incomplete test is always
+   selected.
+
+5. **`gh`, `python3`, and `GH_TOKEN` with `actions: read`** in the PR job, to
+   fetch the bundle. GitHub-hosted runners include `gh` and `python3`.
+
+## Recipe
+
+Copy these files from this repository and adapt the marked lines:
+
+| File | Adapt |
+|---|---|
+| `scripts/ci/test-impact-bundle.sh` | `WORKFLOW=` (producer file name) and the hard-coded `main` branch filter. |
+| `scripts/ci/test-impact-select.sh` | `--lane unit` (your lane name) and the `PLATFORM` default (must equal the producer's). |
+| `scripts/test-impact/selection.py` | Nothing, if your runner accepts `suite` / `suite:test` lines. |
+
+### (a) Producer: publish a bundle for every commit on main
+
+The bundle holds the commit's frozen graph, its coverage map and a
+`receipt.json` that binds both by SHA-256. It is uploaded as the Actions
+artifact `test-impact-<sha>`. `test-impact-bundle.sh` accepts a bundle only
+from a successful `push`, `schedule` or `workflow_dispatch` run of the
+producer workflow, in the same repository, on `main`, whose head is exactly
+the requested commit.

+```
+
+This repository's producer (`.github/workflows/test-impact-artifact.yml` with
+`scripts/ci/test-impact-publish.sh`) adds an incremental mode. A push re-runs
+coverage only for the suites that its own selection picks and merges them into
+the previous map (`coverage-merge.py`). The graph is built incrementally from
+the previous bundle (`--previous`). The weekly run rebuilds everything and
+fails if the incremental graph topology differs from the full one. The
+incremental mode is an optimisation. A full coverage run on every push is
+simpler and just as correct.
+
+The receipt keeps the time of the oldest coverage observation. An incremental
+publish carries it forward unchanged. A map whose oldest observation is more
+than 7 days old is refused (`TOO_OLD`), so a full refresh has to run more often
+than that.
+
+### (b) PR job, shadow mode (report only)
+
+```yaml
+  test-impact-shadow:
+    runs-on: ubuntu-latest
+    continue-on-error: true          # can never block or pass a merge
+    permissions:
+      contents: read
+      actions: read                  # the merge base's bundle
+    steps:
+      - uses: actions/checkout@<pinned-sha>
+        with:
+          fetch-depth: 0
+          persist-credentials: false
+      - name: Install codebase-memory-mcp
+        run: <the pinned install from Prerequisites>
+      - name: Select with the team artifact (shadow)
+        env:
+          GH_TOKEN: ${{ github.token }}
+        run: scripts/ci/test-impact-select.sh --binary "$RUNNER_TEMP/cbm/codebase-memory-mcp" --out "$RUNNER_TEMP/test-impact"
+      - uses: actions/upload-artifact@<pinned-sha>
+        if: ${{ always() }}
+        with:
+          name: test-impact-prediction
+          path: |
+            ${{ runner.temp }}/test-impact/selection-engine.json
+            ${{ runner.temp }}/test-impact/summary-engine.md
+```
+
+Leave this job out of your aggregate required check. What
+`test-impact-select.sh` does:
+
+1. Takes the base side of the PR merge commit (`HEAD^1`) and fetches that
+   commit's bundle.
+2. If the producer skipped that commit (merge bursts: GitHub keeps one pending
+   run per concurrency group), it uses the nearest first-parent ancestor that
+   has a bundle, up to 20 commits back, and diffs against that ancestor. If the
+   PR reverts a change that main made after the ancestor, the ancestor's map
+   cannot speak for that file, so the script selects without coverage (the
+   revert guard).
+3. Passes `--artifact-verified` only for a bundle that it fetched and checked
+   itself. Nothing inside a bundle can assert where the bundle came from.
+4. Runs `test-impact select` and writes `selection-engine.json`. It also
+   writes a Markdown summary to the job's step summary.
+
+The engine reads `.codebase-memory.json` from the **selection base** (the merge
+base, or the ancestor whose bundle was admitted), not from the PR. A PR cannot
+loosen its own selection. A PR that changes the config runs
+everything (`builtin:test-impact-config`).
+
+### (c) Gate job and the test job
+
+```yaml
+  select-tests:
+    if: ${{ vars.TEST_IMPACT_MODE == 'gate' }}
+    runs-on: ubuntu-24.04
+    permissions:
+      contents: read

+      - if: ${{ steps.select.outputs.selection == 'narrowed' }}
+        uses: actions/upload-artifact@<pinned-sha>
+        with:
+          name: test-selection
+          path: ${{ runner.temp }}/test-selection
+          if-no-files-found: error
+
+  test:
+    needs: [select-tests]
+    if: ${{ !cancelled() }}          # a skipped or failed select-tests must NOT skip the tests
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@<pinned-sha>
+      - if: ${{ needs.select-tests.result == 'success' && needs.select-tests.outputs.selection == 'narrowed' }}
+        uses: actions/download-artifact@<pinned-sha>
+        with:
+          name: test-selection
+          path: ${{ runner.temp }}/test-selection
+      - run: ./ci/run-tests.sh          # YOURS: narrows only if test-only.txt is present
+```
+
+With `--gate DIR`, the script runs `selection.py filter … --lane unit` and
+writes `selection=narrowed` or `selection=all` to `$GITHUB_OUTPUT`. A narrowed
+answer writes:
+
+- `DIR/test-only.txt`: one token per line, either `suite` (run the whole
+  suite) or `suite:test`;
+- `DIR/optional-suites.txt`: selected suites that are registered only under a
+  preprocessor condition. A build may lack them.
+
+Everything else means `all`: a `run_all` answer, an unknown schema or filter
+encoding, a filter that disagrees with the lane's suite list, a crash, and a
+lane that selects nothing. The test job then gets no selection and runs every
+test.
+
+**The test job's runner** has to keep the same contract as this repository's
+runner (`scripts/test.sh` → `scripts/run-tests-parallel.sh` →
+`CBM_TEST_ONLY_FILE`, read by `tests/test_main.c`):
+
+- launch only the suites that the tokens name, and only the named tests inside
+  a `suite:test` suite;
+- **fail** when the selection names a suite the build does not register,
+  unless `optional-suites.txt` lists it;
+- **fail** when a selected test cannot be found;
+- **fail** when a selection was promised but the file is missing or empty.
+
+A selection that is silently ignored, or partly ignored, would turn a narrowing
+into missed coverage.
+
+**A runner that starts itself again.** Tests often spawn the test binary as a
+child (`<runner> __probe_x ...`) and its `main` hands over to a probe. A change
+that reaches `main` reaches every test, so the engine runs everything
+(`RUNNER_REACHED`). List the probes instead in a table in the runner's source,
+one entry per line, as `tests/test_main.c` does:
+
+```c
+TF_ROLE(TF_PHASE_SEAMED, "__cbm_sockprobe", tf_maybe_run_socket_probe),
+TF_ROLE(TF_PHASE_WORKER, "--index-worker", tf_maybe_run_index_worker),
+TF_ROLE(TF_PHASE_SPAWNER, "CBM_INDEX_SUPERVISOR", tf_maybe_run_index_worker),
+```
+
+The engine reads the table: a change that only a probe's handler reaches
+selects the tests whose source names one of that handler's literals (the argv
+the child gets, or a switch that lets production code start it), also through
+a `#define` that names the literal. The runner's own use of a literal names no
+spawner. A reached handler that no test names, a table entry the engine cannot
+read, and a change reaching `main` any other way still run everything; the
+engine note names the call chain into `main`.
+
+**Only the legs the coverage speaks for should narrow.** Here the coverage
+comes from one Linux x86_64 clang-21 producer. Only the Linux x86_64 test leg
+downloads the selection (`runner.os == 'Linux' && runner.arch == 'X64'` in
+`_test.yml`). The arm64, macOS and Windows legs always run everything,
+because code under architecture or platform `#ifdef`s has static evidence
+only there. That leg builds with gcc, not clang: code under a compiler `#if`
+has static evidence only too, and `--platform` names the producer's platform,
+so the engine's platform check admits the map by construction.
+
+### (d) Flip the variable
+
+Shadow is the default: the variable is unset, `select-tests` is skipped, and
+every test runs. When the evidence is in, set the repository variable:
+
+```bash
+gh variable set TEST_IMPACT_MODE --body gate      # gate
+gh variable delete TEST_IMPACT_MODE               # back to shadow
+```
+
+Do not add `select-tests` to your required checks or to the aggregate gate.
+When it breaks, PRs cost more minutes. They do not lose coverage.
+
+### Optional: Layer 1 (lanes)
+
+`scripts/ci/select-lanes.sh` is this repository's lane rule set. A `changes`
+job lists the PR's files (the `pulls/{n}/files` API, with a git fallback),
+runs the selector, and writes `tier`, `full`, `lanes` (a JSON list) and
+`reasons` to `$GITHUB_OUTPUT`. Each lane job then runs
+`if: contains(fromJSON(needs.changes.outputs.lanes), '<lane>')`. A single
+aggregate job (`ci-ok`, `scripts/ci/require-all-green.sh`) is the only required
+check. It fails when a *selected* lane was skipped, cancelled or missing.
+
+For your own version, keep these properties:
+
+- An unknown path, an empty list, workflow and harness changes, and a list
+  truncated at the API's 3000-file cap all select every lane.
+- The selector runs from a checkout without credentials, after the step that
+  holds the token.
+- Replay your PR history through the selector and check that every real
+  failure had its catching lane selected. This repository's equivalent is
+  `scripts/test-impact/replay-selector.sh`.
+
+## Configuration: `.codebase-memory.json` → `test_impact`
+
+| Key | Values | Default |
+|---|---|---|
+| `version` | `1` (required) | — |
+| `tests.presets` | `{"c-cbm": true, ...}`. Unknown names are an error. | `c-cbm` off, the six others on |
+| `tests.conventions` | C-family macro records: `case`, `suite`, `registration`, `suite_registration` | none |
+| `rules` | ordered list, see below | none (built-ins only) |
+| `lanes` | list of `{name, suites, exclude_suites?, default: "run"\|"skip", narrow?}` | one lane `unit`: all suites except `@perf`, `narrow: true` |
+| `unmapped_files` | `"run_all"` (the only accepted value) | `run_all` |
+| `coverage.compatibility_paths` | repo-relative files that the coverage map depends on (harness, runner, build flags) | none |
+
+**Rules.** Each rule is `{id, paths, action, ...}`. `paths` are gitignore-style
+globs with `{a,b}` alternatives. A pattern with a `/` is anchored at the
+repository root. Without a `/`, it matches at any depth. `**` matches across
+directories. Project rules come first, then the built-ins. For each changed
+path, **the first matching rule wins**, so order matters.
+
+| `action` | Effect |
+|---|---|
+| `run_all` | Any match runs everything. The summary names the rule (`run_all_rules`). |
+| `ignore` | The path selects nothing. |
+| `referencing_tests` | Selects the tests whose source contains the path as text. The engine tries the path itself, then its parent directories down to the `key`, each with and without its first segment. `key: "path_segment:N"` stops at segment N (zero-based). `key: "path"` tries the exact path only. If no test names the path, everything runs, unless `unreferenced: "ignore"` is set. |
+| `suites` | Runs the named suites whole. |
+| `lanes` | Activates the named lanes (for lanes with `default: "skip"`). |
+
+Built-in rules, applied after yours:
+
+| id | paths | action |
+|---|---|---|
+| `builtin:test-impact-config` | `.codebase-memory.json` | `run_all` |
+| `builtin:build` | `Makefile*`, `CMakeLists.txt`, `*.cmake`, `meson.build`, `BUILD*`, `WORKSPACE`, `package*.json`, `go.mod`, `go.sum`, `Cargo.*`, `pom.xml`, `build.gradle*`, `pyproject.toml`, `setup.*`, `requirements*.txt` | `run_all` |
+| `builtin:ci` | `.github/**`, `.gitlab-ci.yml`, `.circleci/**`, `Jenkinsfile*`, `.buildkite/**`, `azure-pipelines*.yml` | `run_all` |
+| `builtin:vendor` | `vendor*/**`, `third_party/**` | `run_all` |
+| `builtin:conftest` | `conftest.py` | `run_all` |
+| `builtin:documentation` | `docs/**`, `**/*.md`, `LICENSE*` | `ignore` |
+
+**Lanes.** A lane that you declare yourself does **not** narrow unless you set
+`"narrow": true`. `signals` is accepted but has no effect yet.
+
+**This repository's file, explained:**
+
+| Rule | Why |
+|---|---|
+| `harness` → `run_all` | The test framework and the runner's `main` touch every suite. |
+| `engine` → `run_all` | The selection's own code and config. A change to them could loosen what is selected. |
+| `build` → `run_all` | Build and runner scripts: the file list cannot tell a flag change from a harmless one. `/.gitattributes` is anchored at the root. |
+| `grammars` → `run_all` | Vendored parsers are not modelled per test. |
+| `fixtures` → `referencing_tests`, `path_segment:2` | `tests/fixtures/<name>/...` selects the tests that mention the fixture, down to `tests/fixtures/<name>`. |
+| `contracts` → `ignore` | Shell, Python and data contract tests run in every leg's contract step, which is never narrowed. |
+| `notices` → `ignore` | Release notices. |
+| `repo-data` → `referencing_tests`, `path`, `unreferenced: ignore` | Scripts, docs and packaging. A C test whose source names one of these files (its path, as text) is selected. A file that no test names selects nothing. |
+
+`coverage.compatibility_paths` lists the harness and coverage tools. Changing
+the bytes of any of them, or the `--platform` label, makes the existing coverage
+map incompatible until the producer publishes a new one.
+
+## Rollout and evidence
+
+1. **Shadow.** Run (a) and (b). Leave `TEST_IMPACT_MODE` unset.
+2. **Measure.** For each PR run, compare `selection-engine.json` with what
+   failed in that run's full test legs.
+   - A **miss** is a test that failed in the full run but was not selected.
+     One unexplained miss blocks the flip.
+   - **Savings** are the suites and tests that were not selected.
+
+   Nothing in this repository computes misses for Layer 2 yet. Layer 1's
+   history replay (`replay-selector.sh`) is the model to follow.
+3. **Gate.** Set `TEST_IMPACT_MODE=gate`. Keep the shadow job running, so that
+   the evidence keeps coming.
+
+**Reading the step summary** (`### test-impact engine`):
+
+| Line | Meaning |
+|---|---|
+| `decision: \`selected\`` / `\`run_all\`` / `\`nothing\``, then `run-all reasons [...]` | The top-level answer and why everything runs. `decided by rule(s) [...]` names the matched `run_all` rule ids. |
+| `team artifact: fetched (ancestor …)` / `none`; `coverage \`admitted\`` / `\`rejected\` [reasons]` / `\`unavailable\`` | Whether a bundle was used, and whether its coverage was admitted. |
+| `engine note: …` | The engine's first diagnostic line, such as the path that caused `UNMAPPED_FILE`, or the call chain into the runner's `main` for `RUNNER_REACHED`. |
+| `lane \`unit\` (selected): N whole [REASON n, …], M narrowed (K tests)` | Per lane: suites that run whole (with a histogram of reasons), and suites narrowed to K tests. |
+| `the runner-main veto (RUNNER_REACHED) discarded this selection:` | The change reached the runner's `main`, so everything runs. The lines below show what would have been selected otherwise. |
+| `PR CI runs N selection tokens` / `PR CI runs every test (selection exit N)` | Gate mode only: what the test legs received. |
+
+Common run-all reasons:
+
+| Reason | Cause |
+|---|---|
+| `RULE_RUN_ALL` | A `run_all` rule matched (see `run_all_rules`). |
+| `UNMAPPED_FILE` | A changed file matched no rule and is not C-family source. |
+| `RULE_TARGET_UNKNOWN` | A `referencing_tests` path that no test names (without `unreferenced: "ignore"`). |
+| `RUNNER_REACHED` | The change reaches the test runner's `main` (or a child role none of whose literals a test names). |
+| `GIT_UNAVAILABLE` | No git, a shallow clone, or a diff that cannot be read in full. |
+| `CONFIG_INVALID` / `POLICY_UNAVAILABLE` | The merge base's config or rules do not parse. |
+
+Reasons per suite: `ARTIFACT_REJECTED` (no admitted coverage), `SETUP_HIT` /
+`SETUP_UNKNOWN` (the suite's between-test setup ran changed code, or its
+coverage is incomplete), `INVENTORY_UNKNOWN` (the suite cannot be read with
+certainty), `CONDITIONAL` (`#if`-registered), `STATIC` / `CHANGED` / `COVERAGE`
+/ `RULE` (the evidence that selected it).
+
+## Failure modes
+
+Every row below costs CI minutes, not coverage.
+
+| What happens | Result |
+|---|---|
+| No bundle for the merge base | Nearest bundled ancestor, up to 20 first-parent commits back. Otherwise no coverage, and everything runs. |
+| Bundle fetch fails (token, API) | Warning, no coverage, and everything runs. |
+| The PR reverts a change that main made after the ancestor | Revert guard: no coverage, and everything runs. |
+| Coverage older than 7 days, or a platform/compatibility mismatch | Map refused: every suite runs whole. |
+| Shallow checkout | `GIT_UNAVAILABLE`: everything runs. |
+| Engine deadline (default 1800 s) or crash | The job fails. The test job gets no selection, so everything runs. |
+| `select-tests` skipped (shadow) or failed | Everything runs (`!cancelled()` on the test job). |
+| The selection names a suite or test that the build lacks | The test run **fails**: a plumbing fault, reported, never skipped. |
+
+## Known limits
+
+- Narrowing covers C-family source and C test conventions only. Everything
+  else is decided by rules or runs everything.
+- The coverage map format and its producer come from this repository's LLVM
+  toolchain and harness. You need your own equivalent.
+- One producer platform. The selection narrows only the leg that matches the
+  producer's platform; every other leg runs everything. Narrowing more legs
+  needs a producer (and a bundle) per platform.
+- The weekly full refresh and the 7-day age limit are the same length. Each
+  week, when the refresh runs late, there can be a short window in which maps
+  are refused and every test runs.
+- In merge bursts the producer skips commits. The ancestor fallback covers up
+  to 20 of them.
+- The answer schema is `cbm.test_impact.v0` and is marked experimental. It may
+  change between releases. Pin the binary.

+# CBM Lens Beta README captures
+
+These are screenshots and browser recordings of the application, captured on 12–13 October 2026. The application data and text were not retouched. Bernhard Jackiewicz captured the recordings and PNG stills on 12 October. The Explorer and Galaxy JPEG stills were refreshed on 13 October. One addition is drawn on top of the recordings: a small mouse pointer and click ring, because a headless browser shows no pointer of its own.
+
+## Original captures: 12 October

+- Repository: [DeusData/codebase-memory-mcp](https://github.com/DeusData/codebase-memory-mcp)
+- Branch: `main`, after [PR #2068](https://github.com/DeusData/codebase-memory-mcp/pull/2068) brought CBM Lens Beta in
+- Commit: `4d9592b5`
+- Build: `scripts/build.sh --with-ui`
+- Browser: headless Chromium (Playwright) on macOS, English locale, viewport 1440 × 900, device scale factor 1
+- Agents: standard build, experimental agent activity disabled
+
+The `v0.0.1` label in the application is the frontend package version. It is not the backend release version.
+
+### Data shown
+
+The project `codebase-memory-mcp` is an export of the same public commit (`git archive`), indexed in `full` mode into an isolated local cache. No private repository was used. Because the export has no `.git` folder, Explore reports "Git unavailable" in its file impact line.
+
+The index reported 75,037 nodes and 361,349 edges. These are properties of this source scope, not a benchmark. The interface keeps its coverage and display-limit notices.

+`lens-explore.jpg` and `lens-galaxy.jpg` are unedited browser captures at 1280 × 720 from the locally served CBM Lens Beta UI. The running binary reports `dev`; its exact build commit is unavailable, so these captures do not certify an exact source revision. The local project is named `cbm-triage-main-20260919`; the screenshots show public CBM source and indexed relationships.
+
+- **Explore:** `src/foundation/limits.c`, its compact file impact summary and direct dependencies (24 nodes, 26 edges). The UI's freshness, sampling and coverage caveats remain visible.
+- **Galaxy:** `cbm_max_file_bytes`, both directions, all edge types, two layers (160 nodes, 218 edges).
+
+These counts describe the displayed index snapshot, not a benchmark or proof of complete repository coverage. The original recordings and other stills are unchanged.
+
+## Media
+
+| File | What it shows |
+|------|---------------|
+| [lens-overview.gif](lens-overview.gif) | Architecture overview of the repository: zoom and a small orbit, selecting `src/pipeline`, opening that area, selecting `artifact.c` and opening its source. |
+| [lens-architecture.png](lens-architecture.png) | Still image of the whole repository on the architecture map. |
+| [lens-galaxy.gif](lens-galaxy.gif) | Galaxy: searching `cbm_pipeline_run`, following its outgoing calls one layer further, the hierarchy view and the path to `cbm_store_check_integrity`. |
+| [lens-galaxy.jpg](lens-galaxy.jpg) | Two dependency layers around `cbm_max_file_bytes`, with direction and edge-type controls. |
+| [lens-explore.jpg](lens-explore.jpg) | `src/foundation/limits.c` in the reader with its file impact summary, file tree and direct graph dependencies. |
+| [lens-chat.gif](lens-chat.gif) | The chat with the local Qwen2.5 Coder 0.5B model: the explanation of `cbm_pipeline_pass_doclinks` and "Who calls cbm_pipeline_pass_doclinks?" answered from the graph. |
+| [lens-chat.png](lens-chat.png) | Still image of the same explanation and listed answer. |
+| [lens-system-structure.png](lens-system-structure.png) | Component groups and their dependencies in System structure, `src` selected. |
+| [lens-behavior.png](lens-behavior.png) | Possible direct calls of `compileCards`, with its declaration. |
+
+The recordings were captured as browser video, then encoded as GIF at 960 pixels wide and 10 frames per second with a palette per recording. While a search is typed, the Galaxy briefly shows "No matching indexed nodes." until the index search answers; those frames (under one second) were cut. The original PNG stills are 1440 × 900, the chat still 1440 × 1200 so that the explanation and the answer fit together. The refreshed JPEG stills are 1280 × 720. Directional pulses represent indexed relationships, not observed execution.
+
+## Local chat check
+
+The chat recording uses the actual browser model, downloaded through the application's own setup. The explanation lists the indexed facts and the declaration of the selected function; the one sentence after them was written by the model and is labelled as such. The caller answer is listed from the indexed graph without the model.

 - Agent profiles: documented custom-agent formats receive Scout (fast/provisional), Verify (default/task-directed), and Auditor (bounded/full verification) definitions. Every direct tier checks exact path/scope coverage with check_index_coverage and falls back to source for flagged gaps; unsafe child-MCP formats use explicit parent handoff. Kiro and Junie use positive-allowlist Scout/Analysis server profiles (7/11 tools); Qoder combines named-server selection with exact tier-specific MCP tool IDs, while Factory uses exact registered IDs without additive whole-server exposure. Foreign Junie aliases are preserved and force parent handoff.

+# Frontend configuration
+
+Open **System**, then **Configuration**. Settings are grouped by indexing,
+resources, server, diagnostics, and browser. The **External inputs** reference
+covers repository files, installation, launch flags, integration paths, and
+development settings whose owner is outside the running daemon.
+
+## Daemon overrides
+
+Daemon edits are staged until **Save changes**. A batch is validated and committed
+atomically to `_config.db` in the CBM cache directory. Invalid keys or values reject
+the whole batch. Each row exposes its source, default, saved override, current
+process value, and application timing. **Reset** removes the saved override; it
+does not overwrite the inherited environment or replace it with a hardcoded default.
+Legacy environment values outside the registry's canonical format are shown as
+runtime-interpreted inputs, rather than guessed effective values. Saving an override
+requires a validated value.
+
+Supported environment overrides are loaded once when a process starts, ahead of
+the inherited environment and built-in defaults. They do not mutate or export the
+process environment. Restart CBM to apply changes throughout the installation;
+newly launched index workers can load saved values before the existing daemon is
+restarted. Explicit command flags, per-index options, and supervisor recovery caps
+retain their documented precedence.
+
+The existing `auto_index`, `auto_index_limit`, `auto_watch`, `watcher_enabled`, and
+`ui-lang` settings share their canonical SQLite values with CLI configuration.
+UI enablement and port overrides use the same transactional store, with legacy
+UI `config.json` as a fallback. Explicit CLI/UI saves update that store too.
+Concurrent edits use a revision check; a stale save fails without changing data.
+
+Launch locations, filesystem access grants, arbitrary output destinations,
+installer settings, test injection, and supervisor controls are references rather
+than editable process overrides. Platform-specific or unlinked functionality is
+marked unavailable. No generic environment editor or secret enumeration is exposed.
+
+## Browser preferences
+
+Browser changes apply immediately. Graph display and edge motion use their existing
+preference stores. Galaxy budgets, coverage shadow, and architecture appearance
+share a versioned, per-project browser store with the controls in those views.
+Changing these values preserves the current selection. If storage is unavailable,
+preferences remain usable for the current session.
+
+The top-bar agent status opens separate local model controls. Opening configuration never
+downloads weights or starts a model. Repository extension mappings and ignore files
+remain repository-owned and take effect on subsequent indexing.
+
+## Local HTTP API
+
+`GET /api/config` returns `{ revision, settings }`. Each setting declares its type,
+validation bounds or enum choices, lifecycle, provenance, and editability.
+The registry lives in `src/cli/runtime_settings.c`; consumer locations are included
+in its metadata. Browser response validation lives in `src/settings/config-model.ts`.
+
+`POST /api/config` accepts JSON with the revision just read and a nonempty changes
+object. Values are canonical strings; `null` removes an override:
+
+```json
+{
+  "revision": "12",
+  "changes": {
+    "CBM_WORKERS": "4",
+    "CBM_SEMANTIC_ENABLED": "false",
+    "CBM_SQLITE_MMAP_SIZE": null
+  }
+}
+```
+
+Success returns the updated snapshot. Invalid batches return 400, conflicting
+revisions return 409, and storage failures return 500. Existing loopback Host,
+same-origin, and JSON-content checks protect the endpoint. Frontend drafts survive
+errors so users can inspect the conflict before reloading or discarding them.

+# CBM Lens Beta
+
+CBM Lens is the local exploration frontend served by `codebase-memory-mcp --ui=true`.
+It combines source, the indexed graph and optional browser inference. Source files
+are read-only; project architecture decisions can be edited in the ADR workspace.
+The frontend was contributed by Bernhard Jackiewicz as CodeAtlasWeb.
+
+## Explore a project
+
+- **Explore** follows the current file or marked source. Its graph requests direct
+  dependencies separately from the capped repository layout. File-level impact
+  summaries use graph and local Git evidence, with details available on demand.
+- **Galaxy** searches nodes, files and folders. Select a scope and expand incoming
+  or outgoing relationships by depth and edge type. Overview budgets limit drawing;
+  a capped layout does not establish a complete neighborhood. Bounded caches reuse
+  positions and verified adjacency, and fresh index generations invalidate evidence.
+- **Architecture** presents the repository map, routes, hotspots, system structure
+  and behavior. Connectivity clusters are not proof of architectural boundaries.
+  Moving arrows show edge direction, not observed execution. Reduced-motion settings
+  retain stationary direction markers.
+- **Coverage** explains indexing gaps. **System** contains daemon status, indexes,
+  diagnostics and MCP configuration. See [configuration and precedence](CONFIGURATION.md).
+- **ADR** stores one editable Markdown decision document per project through
+  `GET/POST /api/adr`, shared with `manage_adr`. It does not edit repository files.
+
+Use **Add project index** in the project dropdown (or Alt+P) to choose a local
+repository, name its index and follow daemon-reported progress. Files are indexed
+in place, not uploaded. Closing the dialog does not cancel indexing.
+
+ADR drafts stay in this tab's session storage. Before saving, the UI compares the
+server document with the editing baseline and retains conflicting drafts. This is
+not an atomic document lock. Saves are limited to 8,000 UTF-8 bytes and a 16 KiB
+serialized request. The examples in `fixtures/adr/` are explicitly synthetic and
+are never inserted into real projects automatically.
+
+## Local agent
+
+The top-bar agent status opens model configuration; the adjacent chat control folds
+or unfolds the conversation. Model downloads require explicit activation. The chat
+uses browser-local inference; the selected source is not sent to a remote model.
+Model provenance and license limitations are in [THIRD_PARTY.md](THIRD_PARTY.md).
+
+Explorer provides the exact marked text, or the loaded file when nothing is marked.
+A caret alone does not narrow the context. One replaceable source block precedes
+conversation history; each message captures the current selection. Navigation does
+not alter an in-flight request, and Retry uses its original snapshot. Missing or
+partial source is disclosed. Token counting uses the selected model's tokenizer;
+oversized requests are rejected rather than silently shortened.
+
+Automatic explanations respond to new selections independently of follow-up chat.
+Browser history is separated by project, retained for 24 hours, and can be cleared
+in Agent configuration.
+
+## Build and preview
+
+From the repository root:
+
+```sh
+make -f Makefile.cbm cbm-with-ui
+```
+
+This installs the locked frontend dependencies, builds `dist/` and embeds it in the
+native binary. For frontend development, run `npm ci` and `npm run dev` in this
+directory. Vite listens on 5173 and proxies `/api` and `/rpc` to the local server on
+9749. `npm run build` creates a production bundle.
+
+The standalone test preview in `tools/lib/static-proxy.mjs` snapshots `dist/` when
+it starts. Restart that preview after building and compare the served `index.html`
+asset name with `dist/index.html` before reviewing changes.
+
+The canonical frontend CI entry point is `scripts/ci/test-ui.sh` from the repository
+root. It runs unit tests, style and promise checks, acceptance checks and a production
+build. Browser smoke commands require a running server and Playwright Chromium;
+install that browser explicitly with `npx playwright install chromium` when needed.
+
+## Experimental agent activity
+
+Build with `VITE_EXPERIMENTAL_AGENTS=true` to expose recorded tool activity, hook
+setup and graph overlays. The value must be exactly `true`; URL parameters and saved
+preferences cannot enable it. Browser-local chat is independent of this flag.
+Activity remains off until enabled in the UI. It requires an event adapter and is
+not automatic observation of arbitrary coding agents.
+
+The supported adapter is `agents/hooks/atlas-trace.py`. **Connect your agent**
+downloads it and offers a project-specific install command. Review and run it locally:
+
+```sh
+python3 ~/Downloads/cbm-atlas-trace.py --install-claude --root /absolute/repository --project INDEXED_NAME --daemon-url http://127.0.0.1:9749
+```
+
+The installer preserves unrelated settings and hooks, rejects conflicts, symlinks
+and malformed configuration, and writes only the selected repository's
+`.claude/settings.local.json` and `.claude/hooks/`.
+Start a new session in your configured client after installation. Other clients
+need their own adapter.
+
+For manual hook setup, set `ATLAS_PROJECT` to the indexed name, optionally
+`ATLAS_AGENT_NAME` and `ATLAS_DAEMON_URL`, and pass the tool event on stdin. The hook
+records tool, run, sequence, timestamp, path and explicit line ranges. It omits source
+contents, tool output and free-form commands, search patterns and descriptions. Paths
+can still be sensitive. Destinations must be local; proxies and redirects are refused.
+
+A transactional outbox at `~/.atlas-trace/events.jsonl.outbox.sqlite3` buffers up to
+10,000 pending events. `ATLAS_TRACE_FILE` changes the path prefix. Delivery resumes
+on the next hook or `python3 agents/hooks/atlas-trace.py --flush`; one flush sends up
+to 100 events from one project. The older JSONL/replay tools are fixture utilities.
+
+## Activity and diagnostic APIs
+
+`POST /api/agent-events` accepts `{project, events: [...]}` with at most 100 events.
+Each event needs `ts`, `agent`, `run`, integer `seq`, `phase: start|end` and `tool`.
+Optional fields include `path`, `lines`, `detail`, `source`, self-reported `intent`
+and explicit `replay`. Unknown fields are discarded. The UI distinguishes recorded
+facts from self-reports and leaves unmapped paths visible.
+
+The daemon stores activity in `<cache>/activity.db`, independently of replaceable
+project indexes. Monotonic cursors, `(project, run, seq)` identities and retired
+sequence floors prevent duplicate or expired events from reappearing. Retention is
+bounded to 10,000 events; expired history is incomplete. Poll with
+`GET /api/agent-events?project=NAME&after=CURSOR&limit=200` on the graph's origin.
+
+Daemon and frontend logs share the SQLite journal. `GET /api/logs` accepts `project`,
+`scope=unattributed`, `min_level`, literal `q`, `after` and `lines`; filters apply
+before counts and pagination. Unattributed records are not assigned to the selected
+project. Responses identify severity, source, receipt time, durable ID and database
+generation. A bounded memory fallback is explicitly marked `persistent:false`.
+
+`POST /api/ui-log` batches frontend errors and request failures. Failed journal writes
+return 503 for retry. `GET /api/ui-log` reads the same journal; `path` names
+`activity.db`, while `export_path` names the rotating compatibility JSONL export.
+Changing that export does not change HTTP history. These APIs publish nothing
+externally.

+## Galaxy source
+
+The initial scene was adapted from [DeusData/codebase-memory-mcp](https://github.com/DeusData/codebase-memory-mcp),
+`feat/atlas-r1` at `bda46086`, on 2026-08-28. It is MIT licensed,
+Copyright (c) 2025 DeusData; the full license is in the repository's `LICENSE`.
+
+| Lens file | Original under `graph-ui/src` |

+| `src/galaxy/types.ts` | `lib/types.ts` |
+| `src/galaxy/density.ts` | `lib/density.ts` |
+
+Adaptations include component-local canvas access, memoized scene measurements,
+frontend-specific props and types, and revised graph interaction/rendering.
+`NodeTooltipCard.tsx` is a separate implementation using Lens styling rather than
+the original Tailwind tooltip. File headers retain the initial import details;
+subsequent changes are recorded in Git history.

+
+## CodeAtlasIDE provenance
+
+Provider, semantic IR, twin and semantic-search modules were ported from Bernhard
+Jackiewicz's CodeAtlasIDE project by the same author. Their source headers retain
+that origin. They are original contributions from Bernhard, not imports from an
+unrelated third party.
+
+The concept of deriving an entry tour from project structure was inspired by
+Understand-Anything (MIT). `src/tours/tour-generator.ts` contains original Kahn
+traversal, role labels, wording and cycle handling; no source was copied from that
+project. Its direct code origin is CodeAtlasIDE.
+
+## Optional browser models
+
+Transformers.js and ONNX Runtime assets are served locally. Weights are not bundled;
+downloading them requires an explicit browser action. Source inference stays in the
+browser. Model policy pins revisions and permitted files; it does not execute remote
+model scripts.
+
+The following metadata was recorded on 2026-09-08. Download sizes include tokenizer
+and configuration files and do not describe GPU memory requirements.
+
+| Model | Fixed revision | Download bytes | Recorded license |
+| --- | --- | --- | --- |
+| [onnx-community/Qwen2.5-Coder-0.5B-Instruct](https://huggingface.co/onnx-community/Qwen2.5-Coder-0.5B-Instruct) | `f0292f665fd307846ff3c318a91a1bc29d091492` | 566366194 | Apache-2.0 for the base model |
+| [onnx-community/Qwen3-0.6B-ONNX](https://huggingface.co/onnx-community/Qwen3-0.6B-ONNX) | `da1453100cf3ff33ef56d17983fc7a8648706db6` | 578917626 | Apache-2.0 |
+| [LiquidAI/LFM2.5-1.2B-Instruct-ONNX](https://huggingface.co/LiquidAI/LFM2.5-1.2B-Instruct-ONNX) | `10f72e70abf67ac0fd7ebf15bc5854726891d864` | 763763755 | Liquid AI license; review commercial terms above $10M annual revenue |
+| [onnx-community/Qwen3.5-2B-ONNX-OPT](https://huggingface.co/onnx-community/Qwen3.5-2B-ONNX-OPT) | `2ea7886f48b926aca97de8b0e041ffca7e3ebaa9` | 1402850762 | Apache-2.0 |
+
+All use `q4f16`. Qwen3.5 loads the text decoder and embeddings only, not vision
+files. The Qwen2.5 ONNX weight file is 554935833 bytes; its published LFS SHA-256 is
+`60c076ac0d3910881fe0cad75997e803459a5f71bb74bcbcd82407ef83db7ba0`.
+The converter's model card does not declare a separate license; its
+[official base model](https://huggingface.co/Qwen/Qwen2.5-Coder-0.5B-Instruct)
+is Apache-2.0.
+
+`src/browser-ai/model-policy.ts` retains complete file lists, published LFS hashes
+and allowed hosts, including `huggingface.co` and the recorded redirect host
+`us.aws.cdn.hf.co`. The loader does not recompute the published hashes.
+The browser context limit is 8192 tokens including 512 reserved output tokens;
+requests are counted with the selected template and tokenizer rather than silently
+truncated. Qwen3 and Qwen3.5 default to non-thinking mode. Runtime support is not a
+benchmark or a compatibility guarantee for every browser/GPU combination.

+# ADR 0001: Optional local inference and model evidence
+
+## Decision
+
+CBM Lens offers optional browser inference. Weights are downloaded only after the
+user opts in; they are not embedded in the executable. Model selection remains a
+user choice. Browser model IDs, fixed revisions, allowed files and licenses live in
+`src/browser-ai/model-policy.ts`; [THIRD_PARTY.md](../../THIRD_PARTY.md) documents them.
+
+The older GGUF sidecar catalogue remains supported by local scripts and its recorded
+evaluation. It is separate from the browser ONNX catalogue. Its measurements do not
+predict browser performance, another machine's performance or a model's general rank.
+
+## Sidecar model sources
+
+The six Q4_K_M candidates below were recorded in August 2026. Class A used a 3072-token
+context and class B used 8192 tokens. Exact download sizes refer to those evaluated
+files, not runtime memory. Checksums are retained in `models/SHA256SUMS`.
+
+| Model | Class | Download source | Recorded size | License recorded for the base model |
+| --- | --- | --- | --- | --- |
+| Qwen3.5-2B | A | [unsloth/Qwen3.5-2B-GGUF](https://huggingface.co/unsloth/Qwen3.5-2B-GGUF) | 1280835840 Bytes | Apache 2.0 |

+| MiniCPM5-1B | A | [openbmb/MiniCPM5-1B-GGUF](https://huggingface.co/openbmb/MiniCPM5-1B-GGUF) | 688065920 Bytes | Apache 2.0 |

+| Qwen3.5-4B | B | [unsloth/Qwen3.5-4B-MTP-GGUF](https://huggingface.co/unsloth/Qwen3.5-4B-MTP-GGUF) | 2834975040 Bytes | Apache 2.0 |

+
+Review current model-card terms before downloading or redistribution. The recorded
+LFM license allows free commercial use below $10M annual revenue; use beyond that
+threshold requires separate consideration. No evaluation result overrides licensing.
+
+## Evaluation limits
+
+`verification/w5/eval.json` records 44 fixture questions, including 23 in German,
+with temperature 0 and seed 42. The figures below summarize that saved run. Citation
+compliance measures the evaluation's citation rule, not factual correctness.
+
+| Model | Class | Pass rate | Citation compliance | Mean tokens/s, rounded |
+| --- | --- | --- | --- | --- |
+| Qwen3.5-2B | A | 0.682 | 0.932 | 86 |
+| LFM2.5-1.2B | A | 0.295 | 0.432 | 110 |
+| MiniCPM5-1B | A | 0.250 | 0.545 | 171 |
+| Qwen2.5-Coder-1.5B | A | 0.227 | 0.705 | 84 |
+| Qwen3.5-4B | B | 0.818 | 0.955 | 38 |
+| gemma-4-E4B | B | 0.841 | 1.000 | 32 |
+
+The recorded class recommendations were Qwen3.5-2B and gemma-4-E4B, with pass-rate
+and citation thresholds of 0.6 and 0.9. They are recommendations, not installed
+defaults. A reported repeat run has no separate saved artifact and is not independent
+reproduction evidence. The original record does not measure unscorable citations;
+missing measurements must not be displayed as zero.
+
+## Engine boundary
+
+The sidecar evaluation used llama.cpp on Apple Silicon with Metal and GGUF files.
+Its source/build record is in [runtime provenance](../../vendor/llama/HERKUNFT.md).
+`llm/start.sh` also supports a local model cache and OpenAI-compatible transport;
+the class-specific script options reproduce the recorded evaluation.
+
+Browser inference uses a different runtime and format. Compare actual device and
+workload behavior before drawing performance conclusions, especially prompt prefill,
+GPU memory limits and large-file handling. Relevant engine sources retained from
+the original investigation are [llama.cpp](https://github.com/ggml-org/llama.cpp),
+[wllama](https://github.com/ngxson/wllama), [WebLLM](https://webllm.mlc.ai/docs/),
+[Transformers.js](https://github.com/huggingface/transformers.js),
+[WebGPU limits](https://developer.mozilla.org/en-US/docs/Web/API/GPUSupportedLimits),
+and the [ggml WebGPU study](https://arxiv.org/html/2605.20706v1).
+These references explain the formats and tradeoffs; the sidecar timings above are
+not browser benchmarks.

+# Architecture decisions
+
+> Preview examples for cbm-preview. These editable notes capture frontend design choices discussed during development; they are not a historical ADR archive or graph-inferred facts. Status: proposed for review.
+
+## 001: Explain architecture from evidence
+
+**Status:** Proposed · **Scope:** Architecture workspace
+
+### Context
+
+A repository map explains where code lives. System structure and behavior also need to explain relationships, boundaries, and execution steps. A convincing picture should remain traceable to its inputs.
+
+### Decision
+
+Combine indexed graph relationships with source evidence. Keep the repository map, routes, hotspots, system structure, and behavior as distinct lenses. Mark inferred relationships as inferred, and make their evidence inspectable. Do not embed project-specific architectural explanations in the visualization code.
+
+### Consequences
+
+- The same analysis can be applied to other indexed repositories.
+- Missing evidence remains a visible limitation rather than a fabricated connection.
+- A source or graph change can alter the view; these written decisions change only when someone edits them.
+
+**Implementation references:** `graph-ui/src/architecture/`, `src/store/architecture_projection.c`.
+
+## 002: Keep browser AI optional
+
+**Status:** Proposed · **Scope:** Local chat
+
+### Context
+
+Code exploration should work before any model is downloaded. Users may want to ask about a file or a literal code selection without sending source to a hosted model.
+
+### Decision
+
+Run the chat model locally in the browser after explicit setup. Download weights only after opt-in. Attach the selected code or graph context to the next prompt and render answers as Markdown.
+
+### Consequences
+
+| Benefit | Tradeoff |
+| --- | --- |
+| Exploration works without model setup | Chat is unavailable until a model is enabled |
+| Inference stays on the device | Model quality and speed depend on local resources |
+| The prompt can use exact marked code | A bounded context cannot include an entire large repository |
+
+**Implementation references:** `graph-ui/src/browser-ai/`, `graph-ui/src/reader/MonacoReader.tsx`.
+
+## 003: Keep agent activity experimental
+
+**Status:** Proposed · **Scope:** Agents workspace
+
+### Context
+
+The current integration records events from explicitly configured agent hooks. The UI cannot infer every agent operation merely by observing the graph.
+
+### Decision
+
+Hide Agents unless the experimental build flag is enabled. Treat hook events as observed activity, and avoid implying complete task execution, tool outcomes, or duration data.
+
+### Consequences
+
+The default navigation remains focused. Further agent adapters and a richer event contract can be introduced before promoting the view to a standard workspace.
+
+**Implementation references:** `graph-ui/src/app/feature-flags.ts`, `graph-ui/agents/hooks/atlas-trace.py`, `src/ui/activity.c`.

+# Architecture decisions
+
+> Preview examples for the indexed Train Ticket repository. These are proposed review notes for exercising the ADR workspace, not decisions attributed to the upstream maintainers.
+
+## 001: Review services as deployment boundaries
+
+**Status:** Proposed · **Scope:** Routes review
+
+### Context
+
+A large service graph is difficult to understand when every source file has equal visual weight. Deployment declarations provide another useful level of organization.
+
+### Decision
+
+Use detected service and container boundaries to organize the routes review. Keep the declaration behind each boundary inspectable. Treat a deployment dependency and a source-level request as different kinds of evidence.
+
+### Consequences
+
+- The initial view can show relationships between services before drilling into handlers.
+- A declared dependency alone does not prove that a request is sent.
+- Services without discovered connections should remain visible.
+
+## 002: Follow a request through its evidence
+
+**Status:** Proposed · **Scope:** Cross-service investigation
+
+### Context
+
+Matching a caller to a route helps explain the system, but static analysis may not resolve dynamic hosts, route parameters, or runtime configuration.
+
+### Decision
+
+During review, follow a connection from its caller through the route evidence to the destination handler. Keep unresolved destinations visible as unknowns. Use source inspection to verify a suspected relationship before treating it as established.
+
+### Review checklist
+
+- [ ] Inspect an outgoing request in the selected service.
+- [ ] Compare its path and method with the destination route.
+- [ ] Check relevant configuration and service naming.
+- [ ] Record unresolved runtime assumptions here.
+
+### Consequences
+
+This creates a repeatable review path while avoiding claims that a static graph proves runtime behavior.

+# Architecture decisions
+
+> Preview example for voting-services. This proposed review note is test content, not an upstream architectural decision.
+
+## 001: Distinguish declared and observed connections
+
+**Status:** Proposed · **Scope:** Service map review
+
+### Context
+
+A small connected application is useful for checking whether a service visualization makes each relationship understandable.
+
+### Decision
+
+Review deployment dependencies, request relationships, and datastore connections separately. Inspect the source or configuration evidence for each edge. Do not interpret an edge count as traffic volume or a static dependency as an observed runtime call.
+
+### Consequences
+
+The service map can explain what is connected and why without implying measurements that were never collected. Missing connections become concrete questions for further inspection.
+
+### Next review
+
+- [ ] Select a service and inspect its neighboring connections.
+- [ ] Verify one connection against source or configuration.
+- [ ] Edit this note with the outcome and save it.

+# Agent-event fixture provenance
+
+These stable replay inputs exercise activity visualization without requiring a live
+coding session. They contain no source contents or tool output. They are test
+fixtures, not evidence of current agent activity.
+
+## `w11a-replay.jsonl`
+
+Derived from a real tool-hook recording made while working on this repository on
+29-30 August 2026. The private original is not committed because it contains local
+paths and commands. This fixture preserves its event shape, relative tool mix,
+initial timestamp (`1788038561000`) and 44 consecutive time intervals in milliseconds:
+
+```text
+10065, 13599, 115703, 5123, 18182, 6789, 1140, 13387, 5243, 5570, 6676,
+21168, 51146, 6330, 6339, 28257, 4029, 318, 2709, 709, 83, 6176, 1116,
+3373, 3642, 3149, 2275, 4175, 2884, 4066, 2310, 2028, 2838, 33596, 5878,
+17621, 826, 5788, 11062, 6988, 5724, 10001, 17767, 13461
+```
+
+The intervals came from the first 45-event window without a pause over two minutes,
+beginning at line 57 of the original. The following content was deliberately changed:
+
+- Absolute paths became relative `fixtures/atlas-sample` paths. `package.json` is
+  intentionally outside the indexed graph to exercise unmapped activity.
+- One original agent became the synthetic roles `implementer`, `checker` and
+  `explorer`; their eight-character run IDs are invented.
+- Explicit `lines` ranges were added from fixture symbols. The original hook did
+  not record line ranges.
+- Run `b7e4d19c` jumps from sequence 6 to 9 to expose two missing events.
+- Two synthetic `intent` fields exercise explicitly labeled self-reports.
+- `detail` values describe fixture operations instead of retaining private commands.
+
+The result contains 45 events, three runs, four work types, one two-event sequence
+gap, two self-reports and one path outside the index.
+
+## `w11b-replay.jsonl`
+
+Entirely constructed test data, not a session recording. Its paths and line spans
+come from `fixtures/atlas-sample`; timestamps and activity are deliberately chosen.
+
+- Eight agents plus the browser reader exercise the eight-body display limit.
+- `explorer` and `planner` end 75 and 85 seconds before the last event. Both are
+  idle but still within retention; the oldest actor exercises the display cap.
+- `implementer` writes `createUser` lines 23-36 five times in 1.8 seconds to test
+  aggregation into one visible wave, and visits fifteen symbols to exceed trail limits.
+- `reviewer`, `indexer` and `tracer` end at `hotspotScan` in `src/repo/db.ts`, lines
+  39-54, to test deterministic orbit separation at one symbol.
+- Activity rates differ: fifteen recent events for `implementer`, two for `packer`,
+  none for idle `planner`. One `package.json` path remains unmapped and one event
+  has a synthetic self-reported `intent`.
+
+There are 73 events across eight runs and four work types over 145 seconds. Last
+activity offsets are 0, 3.8, 4.4, 5, 7, 10, 75 and 85 seconds for `implementer`,
+`tracer`, `indexer`, `reviewer`, `packer`, `checker`, `explorer` and `planner`.
+The fixture does not encode progress, quality assessments or source contents.

+# Large-source fixture provenance
+
+Generated for this frontend on 2026-08-28; no external code was copied.
+`src/big.ts` deterministically contains 100 small exported functions and `runAll`.
+`src/support.ts` and `src/index.ts` were written for the fixture.
+
+The 717-line source exceeds the 500-line `get_code_snippet` limit and exercises
+`source_clipped`. The reader must disclose missing source rather than presenting
+an incomplete file as complete. This corpus is separate from `atlas-sample` to
+preserve that fixture's graph counts. It is indexing input, not a runnable package.

+Copied from Bernhard Jackiewicz's CodeAtlasIDE project on 2026-08-28,
+`fixtures/atlas-sample`, by the same author.
+
+The twelve TypeScript and configuration files form a deliberately small, stable
+demo and test corpus. Graph assertions depend on that stable source. Changes here
+apply only to this fixture; they do not update its source project.

+# ## Was hier wirklich passiert
+#
+# llama-server kann selbst laden: `-hf user/repo[:quant]` holt die Datei von
+# huggingface.co in das Verzeichnis, das llama.cpp als Cache liest
+# (Umgebungsvariable LLAMA_CACHE, ohne sie auf macOS $HOME/Library/Caches/
+# llama.cpp). Dieses Skript setzt LLAMA_CACHE auf das Cache-Verzeichnis dieses

+# vorhandenen und llm/start.sh es ohne weitere Angabe findet.
+#

+# nicht gibt, die erste Datei des Repositories. Er wird ohne Ansehen der
+# Gross- und Kleinschreibung gesucht.
+#
+# ## Der eine Satz, der vor jedem Lauf dasteht
+#
+# Dieser Befehl GEHT INS NETZ. Er ist damit die eine Stelle, an der dieses

+# Den lokalen Modell-Sidecar starten. Ein Prozess, ein Port, eine PID-Datei.

+# Warum es dieses Skript gibt und nicht einen Knopf in der Oberflaeche: die SPA
+# hat kein eigenes Backend und kann keinen Prozess starten (ADR 0001,
+# Abschnitt "Engine-Entscheidung"). Ein Knopf, der einen Prozess verspricht,
+# waere eine Luege in Knopfform. Der Manager im Browser erkennt, zeigt und
+# leitet an; gestartet wird hier, von Hand oder aus einem Beweislauf.
+#
+# ## Die Vorgabe ist seit W10 der Router, nicht ein Dateiname
+#
+# Ohne Argument faehrt dieses Skript llama-server ueber ein CACHE-VERZEICHNIS:
+#
+#     --models-dir "$ATLAS_MODELS_DIR" --models-max N --models-autoload
+#
+# Damit listet /v1/models, was in dem Verzeichnis liegt, und das Feld "model"
+# einer Chat-Anfrage waehlt daraus aus. Das Einstellungen-Panel kann so zwischen
+# Modellen umschalten, ohne dass jemand einen Prozess neu startet, und ohne dass
+# die Oberflaeche einen Prozess anfassen muesste, was sie nicht darf.
+#
+# Der Grund fuer die Umstellung steht im Nachtrag W10 von docs/adr/0001: das
+# Programm liefert kein Modell mehr aus und nennt auch keins als gesetzt. Welche
+# Datei laeuft, entscheidet der Leser.
+#
+# ## Woher das Cache-Verzeichnis kommt
+#
+# ATLAS_MODELS_DIR, sonst $LLAMA_CACHE (die Umgebungsvariable, die llama.cpp
+# selbst fuer seinen Cache liest), sonst <repo>/models. Das letzte ist kein
+# Notbehelf: models/ IST das lokale Cache-Verzeichnis dieses Projekts. Es ist
+# gitignoriert, sein Inhalt gehoert dem Leser, und llm/fetch-model.sh laedt in
+# genau dieses Verzeichnis, damit ein geholtes Modell in derselben Liste
+# auftaucht wie die schon vorhandenen.
+#
+# ## Aufruf
+#
+#     llm/start.sh                      Router ueber das Cache-Verzeichnis
+#     llm/start.sh <pfad>.gguf          eine bestimmte Datei
+#     llm/start.sh <name>               eine Datei aus dem Cache-Verzeichnis
+#     llm/start.sh hf:user/repo[:quant] direkt von Hugging Face (geht ins Netz)
+#     llm/start.sh class-a              die Reproduktionsgriffe der ADR-Eval
+#     llm/start.sh --print-command [..] zeigt die Befehlszeile und startet nichts
+#
+# Aus der Umgebung: ATLAS_MODEL (wie das Argument), ATLAS_CTX (Kontextfenster),
+# ATLAS_MODELS_DIR, ATLAS_MODELS_MAX (wie viele Instanzen gleichzeitig).
+#
+# ## --print-command, und warum es das gibt
+#
+# Ein Beweislauf soll pruefen koennen, WOMIT dieses Skript den Server aufruft,
+# ohne dafuer ein Modell zu laden. Ohne diesen Schalter muesste er Gigabyte in
+# den Speicher heben, um eine Zeichenkette zu sehen. Er schreibt die Zeile auf
+# stdout, startet nichts und fasst weder Port noch PID-Datei an.
+#
+# Idempotent: laeuft der eigene Sidecar schon, passiert nichts und das Skript
+# endet mit 0. Lauscht etwas ANDERES auf dem Port, wird nichts gestartet und
+# nichts abgeschossen; das Skript sagt, was es vorgefunden hat, und endet mit 3.

+/**
+ * Die Verdrahtung: Projekt aus der Adresszeile, Baum aus dem Graphen, Datei in
+ * den Reader.
+ *
+ * Hier steht der Zustand und sonst nichts Darstellendes. Das Chrome
+ * (src/app/AtlasChrome.tsx) bekommt fertige Werte, der Reader
+ * (src/reader/MonacoReader.tsx) bekommt ein fertiges Dokument. Diese Datei ist
+ * die einzige, die weiss, dass es einen Server gibt.
+ *
+ * Drei Entscheidungen, die man sonst raten muesste:
+ *
+ * 1. **Das Projekt kommt aus `?project=`.** Fehlt der Parameter, wird das erste
+ *    Projekt aus `list_projects` genommen. Gibt es keins, sagt die Oberflaeche
+ *    "no project" und zeigt keinen Baum, statt einen leeren zu zeigen: ein
+ *    leerer Baum waere die Behauptung, das Projekt sei leer.
+ * 2. **Der Baum wird beim Laden aufgeklappt.** `/api/tree` antwortet je Anfrage
+ *    mit einer Ebene, und ein Explorer, der mit zwei zugeklappten Ordnern
+ *    startet, zeigt von einem indizierten Projekt so gut wie nichts. Es wird
+ *    breitenweise nachgeladen, bis ein Deckel erreicht ist; was danach noch
+ *    offen ist, bleibt zugeklappt und laedt beim Klick. Der Deckel wird
+ *    genannt, wenn er greift.
+ * 3. **Eine Datei kommt ueber ihren Modul-Knoten.** Warum es keinen anderen Weg
+ *    gibt und was das kostet, steht in src/reader/file-source.ts.
+ *
+ * Dazu kommt seit W2b die Caret-Strecke des Twins, und die hat drei eigene
+ * Entscheidungen:
+ *
+ * 4. **Aufloesen wird entprellt, Hervorheben nicht.** Ein Caret, der durch eine
+ *    Funktion wandert, soll das Badge sofort mitnehmen, aber nicht bei jedem
+ *    Tastendruck den Graphen fragen. Also wandert `caretLine` sofort und
+ *    `settledCaret` nach 250 ms, und nur das zweite loest auf.
+ * 5. **Dasselbe Symbol wird nicht zweimal geholt.** Der Cache in
+ *    src/twin/ir-cache.ts schluesselt ueber den qualifizierten Namen und legt
+ *    gleichzeitige Anfragen zusammen; hier kommt nur die Regel dazu, bei
+ *    unveraendertem Subjekt gar nicht erst in den Ladezustand zu gehen, damit
+ *    das Panel beim Wandern des Carets nicht blinkt.
+ * 6. **Folgen wechselt das Subjekt sofort und laesst den Editor nachkommen.**
+ *    Der Kopf des Panels nennt ab dem Klick das neue Symbol und der Koerper
+ *    sagt, dass gelesen wird. Die Fakten kommen erst, wenn der Caret in der
+ *    Zieldatei aufgeloest ist: eine IR, die aus dem Klickziel statt aus einer
+ *    Aufloesung gebaut waere, traege eine erfundene Symbolart, und "This is a
+ *    piece of code" ueber einer Funktion ist genau die Sorte kleiner Luege,
+ *    gegen die dieses Panel gebaut ist.
+ *
+ * Seit W3 kommen die Galaxie und die Bedeutungssuche dazu, mit drei weiteren
+ * Entscheidungen:
+ *
+ * 7. **Der Fokus laeuft in beide Richtungen ueber genau einen Schluessel.**
+ *    Das Twin-Subjekt reist als qualifizierter Name zur Galaxie, die Galaxie
+ *    schickt einen angeklickten Knoten als Ziel zurueck durch denselben
+ *    `followTarget`, den auch der Twin benutzt. Es gibt also keinen zweiten
+ *    Navigationsweg, den man vergessen koennte zu pflegen, und keine zweite
+ *    Stelle, an der ein Symbol identifiziert wird.
+ * 8. **Ein Klick in die Galaxie behauptet nichts ueber das Symbol.** Er
+ *    oeffnet die Datei an der gemeldeten Zeile; was dort steht, sagt die
+ *    Aufloesung, so wie beim Folgen aus dem Twin. Der Grund ist derselbe wie
+ *    in Entscheidung 6.
+ * 9. **Getippt wird ohne Anfrage, gefragt wird nach 200 ms Ruhe.** Die
+ *    Kommandozeile ist eine Suche und kein Terminal: sie schickt keine Zeile
+ *    ab, sie zeigt waehrend des Tippens, was der Index kennt. Ohne die
+ *    Entprellung waere jede Taste ein Sweep ueber den Graphen.
+ *
+ * Seit W4a kommen die Einstiegsmodi dazu, und mit ihnen vier weitere:
+ *
+ * 10. **Die Frage nach dem Warum ist eine Flaeche, kein Dialog.** Sie fuellt
+ *     den leeren Editorbereich, wenn keine Datei offen ist und dieser Browser
+ *     fuer dieses Projekt noch keine Antwort kennt. Ein Modal beim ersten
+ *     Oeffnen wuerde die Oberflaeche und jeden automatisierten Lauf durch sie
+ *     blockieren; das ist die Begruendung des Referenzprojekts und sie gilt
+ *     hier unveraendert.
+ * 11. **Eine Antwort setzt genau eine Sache und wird dann vergessen.** Sie
+ *     setzt das Leseprofil des Twins (Tiefe und Linsen, Zuordnung in
+ *     why/why-model.ts) und wird gespeichert, damit die Frage nicht wieder
+ *     kommt. Niemand fragt den Intent spaeter zurueck: ein weitergereichter
+ *     Intent waere ein Modus, und ein Modus ist ein zweites Produkt im ersten.
+ * 12. **Ein Schritt bewegt den Reader ueber dieselbe Strecke wie ein Klick.**
+ *     Ein Symbolschritt geht durch `followTarget`, ein Dateischritt durch
+ *     `openFile`. Es gibt keinen zweiten Navigationsweg fuer Fuehrungen, also
+ *     auch keine zweite Stelle, an der ein Symbol identifiziert wird, und der
+ *     Twin folgt einem Schritt aus demselben Grund, aus dem er einem Klick
+ *     folgt.
+ * 13. **Die stille Anzeige zaehlt Wege, nie Zeit.** Beim Betreten eines
+ *     Schrittes und beim Folgen einer Zeile wird ein Checklisten-Item als
+ *     besucht vermerkt. Verweildauer ist keine Evidenz, und die Statusleiste
+ *     zeigt gar keinen Zaehler, solange es keine Checkliste zu zaehlen gibt,
+ *     statt "0 of 0" zu behaupten.
+ *
+ * Seit W4b sind die beiden letzten Karten der Frage scharf, und mit ihnen
+ * kommen drei weitere Entscheidungen:
+ *
+ * 14. **Der BUG-Assistent uebernimmt das Subjekt des Twins und schiebt
+ *     nichts zurueck.** Er liest neu, wenn ein anderes Symbol vor dem Leser
+ *     steht, und veroeffentlicht selbst nichts: wer zwei Pfade vergleicht, hat
+ *     nicht darum gebeten, dass Reader, Twin und Galaxie unter ihm wegwandern.
+ *     Nur ein Klick auf einen Hop navigiert, und der loest den Namen in diesem
+ *     Moment auf, statt einen gespeicherten Verweis zu benutzen.
+ * 15. **Ein kaputter Ref wird hier abgelehnt und nicht dort.** `detect_changes`
+ *     nimmt ein unbekanntes `since` kommentarlos an und antwortet ueber den
+ *     Arbeitsbaum. Ein Tippfehler ergaebe also eine plausible Antwort auf eine
+ *     andere Frage, und deshalb prueft `refRejection` die Form im Browser und
+ *     der Aufruf unterbleibt. Der Beweislauf zaehlt die Anfragen am Proxy und
+ *     liest diese Zahl als die Behauptung.
+ * 16. **Die beiden Flaechen schliessen einander aus.** Beide brauchen den
+ *     ganzen Platz ueber dem Editor, und zwei ganze Antworten uebereinander
+ *     waeren keine. Escape schliesst, was offen ist; das [a]tlas-Menue macht
+ *     beim Oeffnen der einen die andere zu.
+ *
+ * Seit W4e reicht diese Datei eine Antwort weiter, die sie bisher wegwarf:
+ *
+ * 17. **Der Walk bleibt liegen, solange seine Fuehrung laeuft.** `getClosure`
+ *     liefert einen Graphen; daraus eine Schrittliste zu machen und den Graphen
+ *     zu vergessen hiess, die Tiefe wegzuwerfen, die in ihm steht. Also haelt
+ *     `walk` ihn, und das Graph-Panel zeigt ihn als Hierarchie ab dem
+ *     gewaehlten Einstiegspunkt. Er endet, wenn die Fuehrung endet: ein Bild
+ *     einer beendeten Frage waere eine Antwort, nach der niemand mehr fragt.

+/**
+ * Das Instrument unten rechts: es erklaert, was auf dem Graphen zu sehen ist.
+ *
+ * Es ist ausdruecklich KEIN Dashboard. Was es zeigt, sind die Koerper, die
+ * daneben kreisen, in Worten: wer, welche Art von Arbeit, an welchem Ort, seit
+ * wann, und wie dicht die Ereignisse in den letzten dreissig Sekunden lagen.
+ * Jede Zahl darin ist gezaehlt.
+ *
+ * ## Drei Groessen, und warum es drei sein muessen
+ *
+ * Die schriftliche Gegenrede zum Entwurf verlangt ein sehr kompaktes Instrument
+ * (Richtwert 320 mal 150 Pixel), das Designbild des Nutzers zeigt eine deutlich
+ * groessere Karte je Agent mit Wegzeile, und es traegt selbst einen
+ * EXPAND-Knopf. Beides ist richtig, aber nicht gleichzeitig:
+ *
+ *  - **kompakt** ist der Normalzustand, weil das Instrument den Graphen erklaeren
+ *    und ihn nicht zudecken soll. Eine Zeile je Akteur, und alles, was in dieser
+ *    Zeile nicht Platz hat, kuerzt sich mit einem Auslassungszeichen und steht
+ *    vollstaendig im Tooltip und in der grossen Lage.
+ *  - **expand** zeigt die ausfuehrliche Karte je Akteur, so wie das Bild sie
+ *    zeigt: den ganzen Ort, die Wegzeile, die Zahlen der Laeufe, das letzte
+ *    Ereignis im Wortlaut, und die Liste dessen, was sich nicht verorten liess.
+ *  - **eingeklappt** bleibt eine Zeile, die sagt, wie viele Akteure laufen. Ein
+ *    Instrument, das ganz verschwindet, laesst den Leser vor kreisenden Punkten
+ *    ohne Erklaerung sitzen.
+ *
+ * Die gewaehlte Groesse liegt im Speicher des Browsers und ueberlebt den Reload.
+ *
+ * ## Die Ehrlichkeitsregel dieser Flaeche
+ *
+ * Drei Dinge stehen hier NICHT, und alle drei fehlen mit Absicht:
+ *
+ *  1. **Kein Fortschritt.** Weder ein Balken noch eine Prozentzahl noch ein
+ *     "fast fertig". Diese Oberflaeche sieht Werkzeugaufrufe, nicht Vorhaben;
+ *     wie weit ein Agent ist, weiss sie nicht und kann sie nicht wissen.
+ *  2. **Keine Bewertung.** Kein "gut", kein "haengt", kein "denkt nach". Eine
+ *     Pause zwischen zwei Ereignissen ist eine Pause zwischen zwei Ereignissen.
+ *  3. **Keine erfundene Absicht.** Eine Absichtszeile erscheint NUR, wenn das
+ *     Ereignis ein `intent`-Feld mitbringt, das der Agent selbst geschrieben
+ *     hat, und dann in eigener Schriftfarbe, mit dem Praefix "agent says:" und
+ *     einem Tooltip, der sagt, dass es gemeldet und nicht gemessen ist. Das
+ *     Designbild zeigt an dieser Stelle Zeilen wie "Refactoring
+ *     OrderService.createOrder"; genau diese Zeile ist verboten, solange kein
+ *     Ereignis sie traegt.

+ * Der Zeitstrahl unter dem Graphen: eine Spur je Akteur, ein Strich je
+ * Ereignis.
+ *
+ * ## Warum er ein Strich je Ereignis ist und keine Kurve
+ *
+ * Weil eine Kurve eine Aussage waere. Sie muesste glaetten, und Glaetten heisst
+ * hier, zwischen zwei Werkzeugaufrufen eine Dichte zu behaupten, die niemand
+ * gemessen hat. Ein Strich je Ereignis ist die Ablesung: wo einer steht, war
+ * ein Aufruf fertig; wo keiner steht, war keiner. Die Luecken sind dabei die
+ * interessantere Haelfte des Bildes.
+ *
+ * ## Die drei Lagen und die eine Gefahr
+ *
+ * `live` laeuft mit, `paused` haelt das Fenster an (die Ereignisse laufen
+ * weiter ein), `replay` zeigt den Zustand von damals. Die dritte ist die
+ * gefaehrliche: ein alter Zustand sieht aus wie der jetzige. Sie kennzeichnet
+ * sich darum nicht nur hier, sondern faerbt die ganze Ansicht (siehe
+ * `data-replay` am Panel) und sagt in Worten, wie weit zurueck sie steht.

+/**
+ * Die Farbe und der Buchstabe eines Akteurs.
+ *
+ * ## Warum die Farbe aus der Kennung kommt und nicht aus einer Liste
+ *
+ * Weil derselbe Agent nach einem Reload dieselbe Farbe haben muss. Eine Liste,
+ * die der Reihe nach vergeben wird, gibt dem Agenten die Farbe des Platzes, auf
+ * dem er gerade steht: kommt ein zweiter frueher an, tauschen beide die Farbe,
+ * und der Leser sieht eine Bewegung, die es nicht gab. Die Farbe hier ist eine
+ * Funktion der Kennung, sonst nichts. Zwei Fenster, zwei Laeufe, zwei Tage:
+ * dieselbe Kennung, dieselbe Farbe.
+ *
+ * ## Warum es ein Farbton-Band ist und keine sechs festen Farben
+ *
+ * Sechs feste Farben sind bei sieben Agenten zweimal dieselbe. Das Band gibt
+ * jeder Kennung ihren eigenen Ton und laesst trotzdem die Familie erkennen.
+ *
+ * Und warum GENAU dieses Band: die Knotenfarben dieses Graphen sind Sternfarben
+ * und liegen im warmen Viertel (in der Fixture gemessen: #ff6050 bis #fff0c0,
+ * also Farbton 15 bis 45). Das Band der Agenten beginnt bei 140 und endet bei
+ * 340, also Gruen ueber Cyan und Blau bis Magenta. Damit kann ein Agentenkoerper
+ * nie die Farbe eines Knotens tragen, und die Ebene faerbt keinen einzigen
+ * Knoten und keine einzige Kante um: sie legt sich darueber.
+ *
+ * Die Helligkeit ist fest und hoch (72 Prozent bei 92 Prozent Saettigung). Ein
+ * kleiner Koerper von zehn Pixeln auf einem dunklen Grund muss leuchten, um
+ * ueberhaupt eine Farbe zu haben, und ein Band, in dem auch die Helligkeit
+ * variiert, haette dunkle Mitglieder, die niemand sieht.
+ *
+ * ## Der Buchstabe
+ *
+ * Er ist der zweite Unterschied, damit die Unterscheidung nicht allein an der
+ * Farbe haengt: wer Farben nicht trennen kann, liest den Buchstaben. Er kommt
+ * aus dem Namen, und wenn zwei Namen mit demselben Zeichen beginnen, bekommt der
+ * zweite das naechste Zeichen seines eigenen Namens, das noch frei ist. Vergeben
+ * wird in der Ordnung der Kennungen und nicht in der Reihenfolge des Eintreffens,
+ * damit auch das den Reload ueberlebt.

+ * Was ein Ereignis ist, und welche Art von Arbeit es zeigt.
+ *
+ * Die Ereignisse kommen aus dem SQLite-Journal desselben Daemons; lokale
+ * Werkzeug-Hooks senden ihre Metadaten an /api/agent-events. Historische
+ * Fixture-Bruecken bleiben separate Testwerkzeuge. Dieses Modul ist die einzige
+ * Stelle, die aus einer fremden JSON-Zeile ein Ereignis dieses Produkts macht,
+ * und es hat dabei genau zwei Aufgaben.
+ *
+ * ## 1. Nachsichtig lesen, ohne zu erfinden
+ *
+ * Eine Zeile, der ein Pflichtfeld fehlt, wird weggelassen. Eine Zeile mit
+ * Feldern, die dieses Produkt nicht kennt, wird genommen und die Felder werden
+ * uebergangen: eine Quelle, die mehr weiss, soll nicht daran scheitern, dass
+ * sie es sagt. Was NICHT passiert, ist Ergaenzen: kein erfundener Pfad, kein
+ * geratener Zeilenbereich, keine Absicht, die niemand geschrieben hat.
+ *
+ * ## 2. Die Art der Arbeit ablesen, nicht deuten
+ *
+ * Vier Arten stehen im Contract (lesen, schreiben, suchen, testen), und sie
+ * werden am WERKZEUGNAMEN abgelesen. Ein Werkzeug, das keiner der vier
+ * zugeordnet ist, bekommt `other` und sagt das auch so: "other" heisst hier
+ * "der Werkzeugname sagt nicht, welche der vier es ist" und nicht "sonstiges".
+ *
+ * Die einzige Ausnahme ist die Kommandozeile. `Bash` ist kein Hinweis auf
+ * irgendetwas, denn darin steckt alles: ein `ls`, ein Testlauf, ein Bau. Fuer
+ * genau einen Fall ist der Befehl aussagekraeftig genug, und das ist der
+ * Testlauf: `vitest`, `pytest`, `node --test` und ihre Geschwister sind
+ * Programme, die nur eines tun. Alles andere an der Kommandozeile bleibt
+ * `other`, weil eine feinere Deutung des Befehls Raten waere.

+ *
+ * ## Warum der Uebergang gebogen ist
+ *
+ * Weil man an einer Geraden nicht sieht, ob sie eine Bewegung war. Zwei Koerper,

+ * Agent mit einem zweiten Lauf, und zwei Koerper fuer ihn waeren zwei Wesen, wo
+ * eines arbeitet. Die Laeufe werden trotzdem einzeln gefuehrt, denn die

+ *
+ * ## Wie eine Luecke entsteht
+ *
+ * `seq` zaehlt je Lauf fortlaufend. Kommt nach 6 die 9, fehlen zwei. Das wird
+ * gezaehlt und gemeldet, statt eine lueckenlose Geschichte zu zeichnen.
+ *
+ * Das ERSTE Ereignis eines Laufs zaehlt nie als Luecke, auch wenn es die Nummer

+ * verlorene Nachricht. Was dasteht, ist die Nummer, bei der sie eingestiegen

+ * eine Kurve waere eine Aussage darueber, wie dicht die Arbeit "eigentlich"
+ * war, und dieses Fenster weiss nur, wann ein Werkzeug fertig war.
+ *
+ * ## Die drei Lagen, und warum sie verschieden heissen
+ *
+ *  - **live**: das Fenster endet jetzt und wandert mit.
+ *  - **paused**: das Fenster endet dort, wo der Leser angehalten hat. Die
+ *    Ereignisse laufen weiter ein und stehen nach dem Fortsetzen da; angehalten
+ *    ist das NACHLAUFEN und nicht das Zuhoeren. Ein Pausenknopf, der die Quelle
+ *    abhaengt, waere eine Luecke in der Aufzeichnung, die niemand angefordert
+ *    hat.
+ *  - **replay**: der Leser hat auf eine Stelle geklickt und sieht den Zustand
+ *    von damals. Das ist die gefaehrlichste der drei Lagen, denn ein alter
+ *    Zustand sieht aus wie der jetzige; sie ist darum die einzige, die die

+ * Workspace chrome: header, menu, tabs, explorer, breadcrumbs, reader,

+ * Rein darstellend, und das ist der Punkt: der Reader kommt als `children`
+ * herein, nicht als Import. So laesst sich das ganze Chrome in jsdom pruefen,
+ * ohne Monaco zu laden, und der Beweislauf im Browser prueft danach genau das,
+ * was jsdom nicht kann, naemlich den Editor selbst.
+ *
+ * Die Menuezeile zeichnet nur, was etwas tut.
+ *
+ * Bis W3 war ein Menuepunkt ohne Verdrahtung ein Knopf mit einem `title`, der
+ * sagte, dass er nichts tut; seit W3 galt das Punkt fuer Punkt statt pauschal.
+ * Seit W7a (Nutzerauftrag 2026-08-29) gilt es gar nicht mehr: ein Punkt ohne
+ * Verdrahtung wird NICHT gezeichnet. Ein Tooltip macht aus einer Attrappe keine
+ * Auskunft, sondern eine Attrappe mit Fussnote, und ein Menue, das sich
+ * anklicken laesst und schweigt, ist die Sorte stille Luege, gegen die dieses
+ * Produkt gebaut ist.
+ *
+ * Das ist hier die Notbremse und nicht der Normalfall: welche Punkte es gibt,
+ * entscheidet `messages.menu.items`, und dass jeder davon einen Buchstaben in
+ * WIRED_MENU_SHORTCUTS hat, prueft src/app/shortcuts.test.ts. Faellt eine
+ * Verdrahtung trotzdem einmal aus, fehlt der Punkt, statt stumm dazustehen.
+ *
+ * Die Kommandozeile bekommt ihren Hinweis und ihren `title` von aussen, weil
+ * das, was sie tut, nicht mehr hier entschieden wird.

+ *    ein Kind mit `flex-shrink: 1` gibt Breite her, bis sein Inhalt heraushaengt.
+ *    Die Leiste laesst ihre Kinder jetzt stehen und scrollt selbst (CSS).
+ * 2. **Das Rad scrollt waagerecht.** Ueber einer waagerechten Leiste gibt es
+ *    keine senkrechte Bewegung; eine Radumdrehung dort meint diese Leiste, und
+ *    ein Mausrad ohne waagerechte Achse waere sonst kein Bedienweg.
+ * 3. **Ziehen ist der zweite Weg.** Trackpads koennen waagerecht wischen, Maeuse
+ *    oft nicht, und eine Bildlaufleiste waere in einer 30 Pixel hohen Zeile
+ *    kaum zu treffen. Gezogen wird mit gedrueckter Maustaste; ein Zug unter
+ *    vier Pixeln bleibt ein Klick, sonst waere jeder Tabwechsel ein Zug.
+ * 4. **Der aktive Tab wird geholt.** Wer eine Datei oeffnet, will ihren Tab
+ *    sehen, auch wenn er ausserhalb liegt.

+/**
+ * Der EXPLORER: der Datei-Baum aus der Vereinigung von Graph und Coverage, mit
+ * Maus und mit Tastatur.
+ *
+ * Rein darstellend. Die Zeilen kommen fertig ausgerechnet herein
+ * (flattenTree und mergeCoverageIntoLevels in tree-model.ts), das Nachladen
+ * einer Ebene macht der Aufrufer. Diese Trennung ist der Grund, warum der Baum
+ * ohne Server pruefbar ist: was hier steht, ist Anordnung und Tastenlogik, und
+ * beides braucht kein /api.
+ *
+ * Tastatur ist Pflicht, nicht Zugabe.
+ * Die Liste selbst nimmt den Fokus, die Zeilen tragen einen wandernden Cursor.
+ * Waeren die Zeilen einzeln fokussierbar, muesste man sich durch einen ganzen
+ * Baum tabben, um an den Editor zu kommen.
+ *
+ * Seit W4d traegt jede Zeile ihre Coverage-Stufe, und die ist sichtbar statt
+ * nur vorhanden. Drei Entscheidungen dazu:
+ *
+ * 1. **Dateien tragen ein Zeichen, Ordner einen Punkt.** Der Marker einer Datei
+ *    ist eine Aussage ueber sie selbst, der eines Ordners eine ueber seinen
+ *    Inhalt. Dasselbe Zeichen fuer beides waere die Behauptung, der Ordner
+ *    selbst sei uebersprungen worden.
+ * 2. **Gedimmt wird, was keinen Inhalt hat.** `skipped`, `not-indexed` und
+ *    `ignored` sind Zeilen, hinter denen dieses Produkt nichts zeigen kann.
+ *    Sie ganz wegzulassen waere die Behauptung, es gebe die Datei nicht; sie
+ *    normal zu zeigen waere die Behauptung, ein Klick fuehre irgendwohin.
+ * 3. **Die Legende zeigt nur Stufen, die vorkommen.** Eine Legende, die vier
+ *    Stufen erklaert, von denen drei nirgends stehen, ist eine Legende fuer
+ *    einen anderen Baum. Der ehrliche Quellensatz steht dagegen immer da: er
+ *    handelt von dem, was NICHT im Baum steht, und ist genau dann noetig, wenn
+ *    der Baum vollstaendig aussieht.
+ *
+ * Seit W5c kommt eine vierte dazu, und sie korrigiert die zweite:
+ *
+ * 4. **Jede Datei traegt IMMER ihren Status-Punkt, auch der Gutfall.** Bis
+ *    dahin blieb eine indizierte Zeile unmarkiert, und ein sauberer Baum sah
+ *    aus wie ein Baum, zu dem gar keine Coverage-Antwort da war. Der
+ *    Unterschied zwischen "nichts gemeldet" und "nichts gefragt" ist genau der,
+ *    den dieses Produkt sonst ueberall benennt. Das Buchstaben-Zeichen bleibt,
+ *    wo es war: es traegt WELCHE Stoerung, der Punkt traegt OB eine da ist.

+/**
+ * Die beiden Coverage-Quellen holen und zu einem Befund zusammenlegen.

+ * steht, wer gefragt wird und wie oft. Drei Entscheidungen, die man sonst raten
+ * muesste:
+ *
+ * 1. **Beide Quellen, nicht eine.** `index_status` kappt seine Listen bei 500
+ *    Eintraegen je Klasse (mcp.c, COVERAGE_FILE_CAP) und sagt es ueber
+ *    `truncated`. `check_index_coverage` mit `scopes: ["."]` liest dieselbe
+ *    Tabelle direkt und seitenweise. Wer nur die erste fragt, verliert bei
+ *    einem grossen Projekt genau die Eintraege, wegen derer man fragt; wer nur
+ *    die zweite fragt, verliert die Klassenzahlen und den Kappungs-Hinweis.
+ * 2. **Paginiert wird bis `has_more` false ist, mit einem Deckel.** Der Deckel
+ *    ist kein Misstrauen gegen den Server, sondern gegen eine Antwort, die
+ *    `has_more` sagt und `next_offset` nicht bewegt: ohne ihn waere das eine
+ *    Endlosschleife im Browser. Wird er erreicht, bleibt `has_more` stehen und
+ *    der Join schreibt daraus eine ehrliche Zeile.
+ * 3. **Ein Fehler ist kein leerer Befund.** Scheitert eine der beiden Fragen,
+ *    wirft diese Datei. Ein stiller Rueckfall auf "keine Luecken" waere die
+ *    schlimmste Luege, die dieser Zyklus bauen koennte: ein Baum, der behauptet,
+ *    alles sei indiziert, weil er nicht nachfragen konnte.

+/**
+ * Der Tastentest: was von einem Tastendruck wirklich ankommt, und was diese
+ * Oberflaeche daraus gemacht haette.
+ *
+ * ## Warum es diese Datei gibt
+ *
+ * Nutzerbefund vom 2026-08-29: "alt plus letter funktioniert nur fuer atlas".
+ * An der laufenden Vorschau war er nicht nachzustellen: Alt+a, Alt+w, Alt+b,
+ * Alt+c und Alt+l loesen in Chromium alle aus, bei Fokus auf dem Koerper wie im
+ * Editor, und der Tastendruck kommt mit `code: "KeyW"` und `defaultPrevented:
+ * false` am Fenster an. Ein nicht reproduzierbarer Befund laesst genau zwei
+ * ehrliche Antworten zu: raten, oder messen lassen. Diese Datei ist die zweite.
+ *
+ * Sie beantwortet die vier Fragen, an denen ein Kuerzel scheitern kann, und sie
+ * beantwortet sie an dem Geraet, an dem es scheitert:
+ *
+ *  1. **Kommt der Tastendruck ueberhaupt an?** Steht nach dem Druck nichts im
+ *     Test, hat ihn die Tastaturbelegung, das Betriebssystem oder eine
+ *     Erweiterung vorher abgefangen; dann ist die Anwendung nicht beteiligt.
+ *  2. **Traegt er Alt/Option?** Manche Belegungen schicken Option als
+ *     Zeichenmodifikator und setzen `altKey` nicht.
+ *  3. **Welche physische Taste war es?** Unter macOS macht Option+A ein `å`.
+ *     Deshalb liest die Verdrahtung `code` und nicht `key`, und der Test zeigt
+ *     beides nebeneinander, damit der Unterschied sichtbar ist.
+ *  4. **Hat ihn jemand vor uns verbraucht?** `defaultPrevented` allein sagt das
+ *     nicht: der Griff dieser Oberflaeche bestellt ein erkanntes Kuerzel selbst
+ *     ab. Der Test trennt die beiden Faelle, indem der Griff das Ereignis
+ *     zeichnet, das er verbraucht hat.
+ *
+ * Alles hier ist eine reine Funktion ueber ein Ereignis. Kein DOM, kein React,
+ * keine Zeitmessung: der Test der Hilfeseite zeichnet nur, was hier
+ * herauskommt, und die Unit-Tests pruefen es ohne Fenster.

+/**
+ * Wer eine Taste bekommt: die Kommandozeile, ein Menuekuerzel, oder niemand.
+ *
+ * ## Der Befund, gegen den diese Datei geschnitten ist (2026-08-29)
+ *
+ * Gemessen an der laufenden Vorschau: nach dem Laden liegt der Fokus auf `BODY`.
+ * Wer dann lostippt, sieht in der Kommandozeile NICHTS ankommen, und im
+ * Hintergrund gehen Panels auf, weil die blanken Buchstaben Menuekuerzel waren:
+ * das Wort "create" oeffnete ueber sein `c` die Aenderungsansicht. Aus
+ * Nutzersicht ist das "ich tippe und es passiert nichts", waehrend in Wahrheit
+ * etwas passiert, das niemand wollte. Beides zusammen ist die schlimmste Sorte
+ * Fehler: die Oberflaeche tut etwas anderes als das, was der Leser sieht.
+ *
+ * ## Die Regel, und warum diese und nicht die andere
+ *
+ * Der Contract stellte zwei Wege zur Wahl: (a) die Menuekuerzel auf
+ * Alt/Option umstellen, oder (b) type-to-search, bei dem blanke Buchstaben in
+ * die Zeile fallen und die Panel-Kuerzel eine Bestaetigung brauchen. Gewaehlt
+ * ist (a) ALS TRAEGER und (b) als notwendige Ergaenzung, und das ist keine
+ * Verwaesserung der Wahl, sondern ihr Ergebnis: (a) allein loest nur die zweite
+ * Haelfte des Befundes. Waeren die Buchstaben nur frei, wuerde Tippen ohne Klick
+ * weiterhin nichts tun, und genau das ist der Satz, den der Nutzer geschrieben
+ * hat. Und sobald blanke Buchstaben in die Zeile fallen, MUSS ein Kuerzel einen
+ * Modifikator tragen, sonst waere es unerreichbar, sobald die Zeile den Fokus
+ * hat. Die beiden Wege sind also nicht Alternativen, sondern die zwei Haelften
+ * derselben Loesung; die Wahl liegt darin, welcher Modifikator es ist, und das
+ * ist Alt/Option, weil genau das die Konvention einer Menueleiste ist.
+ *
+ * Also gilt, an einer Stelle und deshalb pruefbar:
+ *
+ *  1. **Alt/Option + Buchstabe ist ein Menuekuerzel**, ueberall, auch waehrend
+ *     jemand tippt. Gelesen wird `event.code` und nicht `event.key`: unter macOS
+ *     erzeugt Option+A ein `å`, und ein Kuerzel, das auf den Buchstaben schaut,
+ *     waere dort taub.
+ *  2. **`?` bleibt ohne Modifikator die Hilfe**, solange nirgends getippt wird.
+ *     Es ist die eine Ausnahme, und sie ist begruendet: `?` ist seit
+ *     Jahrzehnten die Hilfetaste, es beginnt kein Wort, das jemand sucht, und
+ *     sobald die Zeile den Fokus hat, tippt es sich ganz normal.
+ *  3. **`/` holt die Kommandozeile**, ohne selbst in ihr zu landen. Dieselbe
+ *     Konvention wie anderswo, und die Hilfe nennt sie.
+ *  4. **Jedes andere druckbare Zeichen gehoert der Kommandozeile.** Die
+ *     Oberflaeche holt sie sich und schreibt das Zeichen hinein.
+ *  5. **Das Leerzeichen nicht.** Es aktiviert einen Knopf und klappt eine
+ *     Baumzeile auf; es zu stehlen hiesse, die Bedienung mit der Tastatur
+ *     ueberall sonst kaputtzumachen, und keine Suche beginnt mit einem
+ *     Leerzeichen.
+ *
+ * Was WEITER gilt und hier nicht steht: die vier Tasten einer laufenden
+ * Fuehrung (tour-player.ts) bleiben blank. Ihre Karte steht auf dem Bildschirm
+ * und schreibt sie hin; wer eine Fuehrung laufen laesst, sieht `[q] exit` und
+ * `[d] diagram` vor sich. Die Oberflaeche laesst der Fuehrung ihre vier Tasten
+ * und schickt alles andere in die Zeile (siehe App.tsx, dort steht die
+ * Reihenfolge).

+/**
+ * Der Datei-Baum, wie ihn der Explorer zeigt: die VEREINIGUNG aus dem Graphen
+ * und den Coverage-Listen des Servers.
+ *
+ * `/api/tree?project=X&path=Y` antwortet mit genau einer Ebene: den direkten
+ * Kindern von Y, jedes mit `name`, `path`, `kind` ("dir" oder "file") und den
+ * Zahlen `symbols` und `files`. Der Baum kommt also stueckweise, eine Ebene je
+ * Anfrage, und dieses Modul haelt die Ebenen zusammen und rechnet aus, welche
+ * Zeilen davon gerade sichtbar sind.
+ *
+ * **Der Graph ist nur eine der Quellen.** Bis W4c war er die einzige, und damit
+ * zeigte der Explorer genau die Dateien, aus denen Symbole geworden sind. Eine
+ * Datei, die der Indexer uebersprungen hat, war unsichtbar, und Unsichtbarkeit
+ * ist in einem Explorer die Behauptung, es gebe sie nicht. Seit W4d stehen
+ * daneben zwei weitere Quellen, beide vom selben Server:
+ *
+ * - `index_status` traegt eine Coverage-Beilage: `parse_partial` (indiziert,
+ *   aber mit Parse-Fehlern), `skipped` (gar nicht indiziert, mit Grund) und
+ *   `not_indexed` (nach Absicht ausgeschlossen, Dateien UND Verzeichnisse).
+ *   Jede der drei Listen nennt ihre eigene Zahl und ihr eigenes `truncated`.
+ * - `check_index_coverage` mit `scopes: ["."]` listet die Eintraege des
+ *   Coverage-Stores selbst, paginiert ueber `scope_offset`, und deckt damit
+ *   auch Faelle, die `index_status` kappt.
+ *
+ * Der Coverage-Store ist eine eigene Tabelle NEBEN dem Graphen (mcp.c: "coverage
+ * is metadata ABOUT the graph, stored outside it"). Darum ist die Vereinigung
+ * keine Bequemlichkeit, sondern die einzige Form, in der der Explorer beide
+ * Wahrheiten gleichzeitig zeigen kann: was indiziert wurde, und was der Index
+ * angefasst und liegengelassen hat.
+ *
+ * Was danach immer noch fehlt, wird nicht verschwiegen: eine Datei, die die
+ * Discovery nie gesehen hat, steht in keiner der drei Quellen. Die Legende im
+ * Explorer-Fuss sagt das mit eigenen Worten, statt den Baum vollstaendig
+ * aussehen zu lassen.
+ *
+ * Zwei Eigenheiten des Graph-Baums bleiben, an einem laufenden Server
+ * abgelesen und hier ausdruecklich behandelt, statt sie im Explorer als
+ * Geisterzeilen zu zeigen:
+ *
+ * 1. **Ordner erscheinen doppelt.** Der Server gruppiert alle Knoten nach
+ *    `file_path`. Ein Folder-Knoten traegt als `file_path` den Ordnerpfad
+ *    selbst, also faellt zu `src` ein zweites Kind an, diesmal mit
+ *    `kind: "file"`. Zwei Kinder mit demselben Pfad sind aber ein Ding: der
+ *    Ordner. Sie werden zusammengelegt, der Ordner gewinnt, und wie oft das
+ *    passiert ist, steht in `foldedDuplicates`.
+ * 2. **`{}` ist kein Pfad.** Die Project- und Branch-Knoten des Projekts
+ *    tragen `{}` als `file_path`, und der Server macht daraus brav ein Kind
+ *    namens `{}`. Eine Datei dieses Namens gibt es nicht. Solche Kinder fallen
+ *    weg und werden in `droppedNonPaths` gezaehlt, damit der Explorer sagen
+ *    kann, dass er etwas weggelassen hat, statt es zu verschweigen.
+ *
+ * Beides ist ein Serverbefund und gehoert auf die Ask-Liste, nicht in eine
+ * stille Reparatur: gezaehlt wird, was wegfaellt.
+ */
+
+/**
+ * Wie weit der Index eine Datei erfasst hat.
+ *
+ * Die fuenf Werte sind genau die Klassen, die der Server meldet, und keine

+/**
+ * Wiring the frontend log into a page: console, window, promises, clients.
+ *
+ * Four feeds, and each one is a place where an error would otherwise stop:
+ *
+ *  1. **The console.** Every console method still prints, exactly as before;
+ *     the wrapper calls the original first and records second. Arguments
+ *     are rendered the way a reader would want them in a file: strings as
+ *     they are, an Error as name, message and stack, anything else as JSON
+ *     with cycles and length held in check.
+ *  2. **Uncaught errors** (`window.onerror` as the `error` event), with file,
+ *     line and column when the browser has them.
+ *  3. **Unhandled promise rejections.**
+ *  4. **Caught request failures**, announced by the /rpc and /api clients
+ *     through the observer seam (provider/error-observer.ts). These are the
+ *     ones the panels show as a sentence and the console never sees.
+ *
+ * The buffer is flushed with `final` on pagehide and when the tab is hidden,
+ * so the last lines of a session reach the file (ui-log-transport.ts uses a
+ * beacon for that). A re-entrancy guard makes sure nothing recorded from
+ * inside a record call comes back around.
+ *
+ * The first entry of a session says which page, which build and which
+ * browser, because a log file that holds several sessions needs a line
+ * where each one starts.

+/**
+ * The frontend's log, on its way to the server.
+ *
+ * The browser console is where this window has always written, and it stays
+ * that way: the console is the reader's view. But the console lives and dies
+ * with the tab. Nothing there reaches the process that serves the page, so a
+ * reader who saw a panel fail had nothing to hand over, and an agent looking
+ * into the failure had nothing to read. This buffer is the second copy: every
+ * console call, every uncaught error, every rejected promise and every failed
+ * /rpc or /api request is queued here and posted to POST /api/ui-log, which
+ * persists it in the local SQLite journal and a bounded compatibility JSONL
+ * export on the same daemon (src/ui/http_server.c).
+ * The file is what a bug report attaches and what `tail -f` reads.
+ *
+ * The rules of the buffer, and why each is there:
+ *
+ *  - **Batched, not chatty.** Entries wait up to UI_LOG_FLUSH_MS and go out
+ *    in groups of at most UI_LOG_BATCH_MAX. A page that logs once per frame
+ *    must not turn into a request per frame.
+ *  - **Bounded.** UI_LOG_BUFFER_MAX entries wait while the server does not
+ *    answer; the oldest are dropped first, and the next batch that gets
+ *    through starts with a line that says how many were lost. A log that
+ *    silently forgets is worse than one that says it forgot.
+ *  - **Backs off.** A failed post is retried on a growing delay
+ *    (UI_LOG_BACKOFF_MS). An unreachable server is a fact the reader sees in
+ *    the header chip; hammering it from here would add nothing.
+ *  - **Never loud.** Nothing in this file writes to the console. The console
+ *    wrapper (ui-log-install.ts) feeds this buffer, so a line written from
+ *    here would come straight back.
+ *  - **Capped fields.** Every text field is cut at UI_LOG_FIELD_MAX
+ *    characters, the same cap the server applies; a cut is marked so nobody
+ *    reads a truncated stack as a complete one.
+ *  - **Once per session, then counted.** An entry identical to an earlier
+ *    one of this session (level, source, project, message, detail, stack and
+ *    place) is counted, not queued. A deprecation warning that a library
+ *    prints on every scene mount (THREE.Clock from @react-three/fiber) would
+ *    otherwise push the real messages out of System › Logs. The count goes
+ *    out as one more entry with the same fields at 10, 100, 1000 repeats and
+ *    when the page is left (`final`), so the journal holds a handful of
+ *    lines, not hundreds. The same message from another place or with
+ *    another response body is another entry and is recorded in full.
+ *  - **One page per post.** The server files every entry of a post under
+ *    the post's page. A project switch stays in the page and only changes
+ *    the address (app/project-windows.tsx), so each entry keeps the page it
+ *    was recorded on, and a batch never spans two of them.
+ *
+ * Time and timers are injectable so a test runs in one tick.

+/**
+ * The answer panel: what the model said, which cards it was given, and how much
+ * of the neighbourhood went into them.
+ *
+ * Purely presentational, like every other panel in this project: what was asked
+ * and what came back is decided in App.tsx, and this file decides what that
+ * looks like. Four things it does that a plain transcript would not.
+ *
+ * **Citations are buttons.** A `[K3]` in the answer is rendered as a control
+ * that navigates to the card's source, through the same `follow` path a twin row
+ * or a galaxy node uses. There is no second navigation route, so there is no
+ * second place that could disagree about where a symbol lives. A citation naming
+ * a card that was never handed over is rendered as plain text with a warning:
+ * a button that navigated nowhere would be worse than no button.
+ *
+ * **The cards fold open.** The answer is four lines; the evidence under it is
+ * ten cards. Showing both at once would bury the answer, and showing only the
+ * answer would make a local model's output look like an oracle's. So the cards
+ * are one click away and the count is always visible.
+ *
+ * **The depth control sits next to the answer it changed.** Martin's context
+ * rule is a setting, and a setting that lived in a preferences dialog would be
+ * a setting nobody connects to the answer in front of them. It carries the
+ * honest note that more neighbours change the answer rather than improve it.
+ *
+ * **Every line under the answer says where it comes from.** The question class,
+ * the rule that fired, the token cost against the budget, and what the compiler
+ * could not fetch. A reader who disagrees with an answer can see, without
+ * asking anybody, whether the model was wrong or whether it was handed the
+ * wrong cards.
+ *
+ * ## What W7c added, and where each of them lives after W8
+ *
+ * **The head does not scroll away.** The depth control changes the NEXT
+ * question, so it has to be in reach while the reader is reading the last one.
+ * It sits outside the scrolling area rather than inside it with `position:
+ * sticky`, which is the same picture with one fewer way to go wrong. Unchanged.
+ *
+ * **Closing and clearing are two different acts and say so.** Until W7c there
+ * was one button, `clear`, and folding the panel away cost the whole session.
+ * Since W8 the chat is a tab of the explain zone, so the folding belongs to the
+ * zone and its handle, and Escape folds the zone. What was won here is not
+ * weaker for it, it is wider: folding costs nothing for any of the five tabs,
+ * the folded strip names what is still in each of them, and `clear` is still
+ * the only thing in this product that deletes a session. It says so in its
+ * tooltip, which now also says what folding does NOT cost.
+ *
+ * **The height is the zone's.** W7c gave this panel its own drag handle,
+ * because it was the only surface with a height nobody could change. The zone
+ * has one now, for all five tabs, with the same bounds, the same keyboard, the
+ * same memory across a reload (src/layout/layout-model.ts). A second height
+ * inside the zone would be a second answer to the same question.
+ *
+ * **An ambiguous name is a question back to the reader.** When one written name
+ * reached several symbols, the turn carries the candidates instead of an answer
+ * and each of them is a button: name, file, line. Pressing one asks the same
+ * question again about that symbol. The alternative, taking the first one and
+ * saying so in a note under the answer, is a choice made for the reader in the
+ * place they read last.

+/**
+ * One question, end to end: classify, fetch, compile, ask, check.
+ *
+ * The five steps live in five files and this one puts them in order. It exists
+ * so there is exactly one path from a typed sentence to a rendered answer, and
+ * so the eval can walk that same path without a browser. A second orchestration
+ * for the measurement would measure something the product does not do.
+ *
+ * ## The order is the argument
+ *
+ * 1. **classify** (no model, no round trip)
+ * 2. **fetch** the class's recipe over the provider, bounded by the depth
+ * 3. **compile** the facts into numbered cards, bounded by the token budget
+ * 4. **ask**, but only if there is at least one card
+ * 5. **check** every claim line against the cards that were given
+ *
+ * Step 4 is conditional and that is the honest half of the design. A question
+ * the index cannot answer produces no cards, and a model asked with no cards can
+ * only invent. So it is not asked: the agreed sentence is returned without a
+ * request, which is both cheaper and truer than teaching a 1B model to refuse.
+ *
+ * Since W7c there is a second reason not to ask: the name in the question
+ * reached several symbols equally well. The model cannot resolve that, because
+ * the ambiguity is in the index and not in the sentence. The turn comes back as
+ * `needs-choice` with the candidates, the reader picks one, and the same
+ * question is asked again with the picked qualified name.
+ *
+ * Step 5 never rewrites the answer. A line without a citation is shown as the
+ * model wrote it, with a warning above it, because hiding it would hide the
+ * failure the eval exists to count.

+ * The one request this product ever sends to a model.
+ *
+ * OpenAI-compatible `POST /v1/chat/completions` against the sidecar on
+ * 127.0.0.1:4141, and nothing else: no streaming, no tools, no function calls,
+ * no second endpoint. The reasons are in PLAN paragraph 5 and they are product
+ * decisions rather than simplifications. A tool call would let the model decide
+ * what to look up, and the whole point of the context compiler is that the graph
+ * decides that. Streaming would make an answer visible before the citation check
+ * has run, which would put an uncited claim on the screen for as long as it takes
+ * to finish.
+ *
+ * ## Three settings are fixed and one is not
+ *
+ * `temperature` is 0 and `seed` is {@link CHAT_SEED}, because the eval compares
+ * six models against forty questions and a run that could not be repeated would
+ * compare nothing. `chat_template_kwargs` carries the non-thinking switch the
+ * prompt contract measured per model. `max_tokens` is the one knob a caller
+ * moves, because a refine of a twenty-line block needs more room than a
+ * four-line answer.
+ *
+ * Since W10 there is a fifth field and it is optional: `model`. Without a choice
+ * it is not in the body at all, so the request is exactly the one this file has
+ * always sent. See {@link ChatRequest.model} for why it is not sent by default.
+ *
+ * ## Reasoning content is read, and it is not an answer
+ *
+ * A model whose template ignored the non-thinking switch answers with an empty
+ * `content` and a full `reasoning_content`. That is reported as
+ * {@link ChatReply.thoughtOnly} rather than papered over by falling back to the
+ * reasoning text: an internal monologue is not an answer under the citation
+ * contract, and a surface that showed one would be showing the model's guesses

+ * What Enter means in the command line, now that the line does two jobs.

+ * behaviours without either of them becoming unreliable, and the contract is
+ * explicit about which one wins: **the search keeps priority.** A reader who
+ * typed three letters and sees the symbol they wanted must still be able to
+ * press Enter and land in it, exactly as before this cycle.
+ *
+ * That leaves the question of what "free text" is, and it is decided here by two
+ * signals rather than by a mode switch:
+ *
+ * **A line that ends with a question mark is a question.** It is the one mark
+ * that nobody types into a symbol search, in either language, and it means the
+ * same thing in both. "Wer ruft createUser?" is a question even though the
+ * search would happily find `createUser`; without this rule the flagship
+ * question of this cycle would navigate instead of asking.
+ *
+ * **A line that starts with `@` is a question.** The answer contract tells the
+ * model to say "fetch it with @name" when a card is missing, so `@name` has to
+ * do something when the reader types it back.
+ *
+ * **A line the search answered with nothing is a question.** This is the free
+ * text of the contract in its literal sense: text that names no symbol. The
+ * search must have finished for this to fire, which is why {@link CommandState}
+ * carries `answered`: sending a question because a debounce has not elapsed

+ * content writes different JSX rather than a second interpretation.
+ *
+ * The one rule the whole file exists to keep is that exploration and

+/**
+ * The quiet record of what a reader has been taken to, per project.
+ *
+ * In the reference project this lives in the workspace, written by a backend
+ * (`node/understanding/`) into `.codeatlas/state/understanding.json`. There is
+ * no backend here and no workspace to write into: the server this frontend talks
+ * to answers a read-only allowlist and offers nothing that stores a reader's
+ * state. So the record lives in this browser's own `localStorage`, and the
+ * surface says so in as many words. That is a weaker promise than the reference
+ * makes and it is stated rather than hidden: clearing site data forgets it, and
+ * a colleague opening the same project on their machine starts empty.
+ *
+ * Three rules survive the move unchanged, because they are what the record is:
+ *
+ * **Item ids are the generator's ids.** They come from
+ * `src/ir/checklist-generator.ts`, which hashes the category and what the item
+ * points at, so a mark survives a reindex and a move of the repository. Nothing
+ * here derives an id of its own; a second derivation is one refactor away from
+ * agreeing with nothing.
+ *
+ * **Only exploration is written automatically.** `markVisited` records that the
+ * reader was taken to an item. Confirmation is a separate field that only an
+ * explicit tick may set, and this module keeps them apart rather than folding
+ * them into one number.
+ *
+ * **Time spent is never evidence.** Nothing here records a duration, a visit
+ * count or a timestamp. Being somewhere is not understanding it, and a record
+ * that counted seconds would be inviting exactly that reading.

+/**
+ * What counts as a kept promise in a model's answer.
+ *
+ * One file, read by three consumers that must never disagree: the chat panel,
+ * which turns `[K3]` into a button; the eval, which marks an answer red when a
+ * claim carries no citation; and the refine path, which rejects a rewrite that
+ * changed the list. Two implementations of "does this line cite a card" would
+ * eventually let the panel render a citation the eval had already called a
+ * violation.
+ *
+ * ## The rule, stated once
+ *
+ * **Every claim line carries a citation.** A claim line is a non-empty line of
+ * the answer that is not the agreed no-card sentence. It must contain at least
+ * one `[Kn]`, and every `[Kn]` it contains must name a card that was actually
+ * given. A number nobody handed over is an invented source, which is worse than
+ * no source at all: it looks checkable and is not.
+ *
+ * **The no-card sentence is exempt, and only it.** A model that was given cards
+ * which do not answer the question is supposed to say so, and that sentence
+ * cites nothing because there is nothing to cite. It is recognised by its
+ * marker rather than by an exact string match, so a German answer that says
+ * "keine Karte" is accepted as readily as the English one the contract asks
+ * for. Everything else with no citation is a violation.
+ *
+ * **A citation is a range or a single number.** `[K3]` and `[K3, K4]` both
+ * occur naturally; both are read, and both are checked.

+/**
+ * Graph facts to numbered cards, under a hard token budget.
+ *
+ * This is the half of the context compiler that decides what a 1B model gets to
+ * see. The recipe before it fetched more than fits; the answer contract after it
+ * forbids saying anything that is not on a card. So everything that matters
+ * happens here: what becomes a card, in which order, in which words, and what
+ * is left out when the budget runs out.
+ *
+ * ## Four rules
+ *
+ * **A card is short, numbered and citable.** `K1`, `K2`, at most
+ * {@link MAX_CARD_LINES} lines each, and every card carries the place it came
+ * from so a `[K3]` in an answer can be turned into a click. A card that could
+ * not name a place would be a claim a reader cannot check, which is the one
+ * thing this product does not put on a screen.
+ *
+ * **The vocabulary is canonical, not descriptive.** Cards say `calls`,
+ * `raises`, `reads`, `is called by` and nothing else, and every reference is
+ * `name (path:line)` or `[line n]`. A card that varied its verbs would be the
+ * compiler writing prose, and prose is what the model is for. The shape is the
+ * one PLAN paragraph 6 names:
+ * `K3: createUser (src/services/userService.ts:23) calls validateUser [line 24]`.
+ *
+ * **The budget is hard and it is in this file.** {@link CARD_BUDGET_CLASS_A} is
+ * 3000 tokens for the roughly 1B class and {@link CARD_BUDGET_CLASS_B} is 8000
+ * for the roughly 4B class, which are the two numbers PLAN paragraph 5 sets
+ * against the two context windows llm/start.sh opens (3072 and 8192). Cards are
+ * added in priority order until the next one would cross the line, and then the
+ * adding stops. Nothing is trimmed in the middle of a card: half a fact is
+ * worse than a missing one, because a reader cannot see that it is half.
+ *
+ * **What was cut is counted and said.** Every drop produces a line on the final
+ * card, in the form "7 more callers not listed". The note is a card of its own
+ * rather than a footer, so the model can cite it: an answer that says "there are
+ * further callers I was not given [K9]" is a correct answer, and one that quietly
+ * lists five of twelve is not.
+ *
+ * ## The token estimate is a heuristic, and it says so
+ *
+ * There is no tokenizer in the browser and shipping one for a budget check would
+ * be a megabyte of dependency to avoid a rounding error. {@link CHARS_PER_TOKEN}
+ * is four characters per token, which is the usual figure for byte-pair
+ * vocabularies on English and code and which errs on the safe side for German
+ * compounds (they cost more tokens per character, so the estimate under-counts
+ * and the compiler cuts earlier than it has to). The measured prompt size of
+ * every eval run is written next to the estimate in verification/w5/eval.json,
+ * so the size of the error is on the record rather than assumed away.

+/**
+ * One fixed recipe per question class: which graph facts are fetched, from
+ * where, and how far out.
+ *
+ * The classifier says what was asked; this file says what to look up. Nothing
+ * here decides anything about wording, and nothing here talks to a model. A
+ * recipe is a list of provider calls with a bound on it, and the bound is the
+ * whole reason a 1B model can answer at all: the compiler that follows turns
+ * this packet into cards under a hard token budget, and a packet that grew with
+ * the repository would make the budget cut off a different half of the answer
+ * every time.
+ *
+ * ## Martin's context rule (voicemail 2, 2026-08-28)
+ *
+ * The default context is the code level the reader is looking at plus the FIRST
+ * neighbourhood: the symbol itself, its direct callers and its direct callees.
+ * A setting in the chat moves that between {@link NEIGHBOR_DEPTHS} 0, 1 and 2
+ * hops, with 1 as the default, and the surface says out loud that more
+ * neighbours can change the quality of the answer rather than only improve it.
+ * The token budget stays the hard limit either way: depth widens what is
+ * offered, the card compiler still cuts at the budget and says how much it cut.
+ *
+ * That rule is why the neighbourhood is gathered the same way for every class.
+ * The class decides which family is emphasised and what else is fetched beside
+ * it; it never decides how far out "nearby" reaches, because a reader who set
+ * the depth to two meant two for every question they ask afterwards.
+ *
+ * ## Two hops are cheap and the third is not
+ *
+ * Hop one costs nothing beyond the subject's own IR: a caller row already
+ * carries the file and the line of its call site, and a call site already
+ * carries the callee's file and declaration line. So the default depth adds no
+ * round trip at all. Hop two has to ask the index about each neighbour, so it
+ * is capped by {@link NEIGHBOUR_HOP2_SEEDS} and the cap is reported. There is no
+ * hop three: a walk that far out is the closure view's question, not a chat
+ * answer's.
+ *
+ * ## What every recipe reads, and what it says when it cannot
+ *
+ * The sources of each class are declared in {@link RECIPE_SOURCES} and the
+ * packet repeats the ones it actually used, so an answer can be traced back to
+ * the calls that produced it. Every absence is a note rather than an empty
+ * list: "the index records no caller" and "nobody asked for callers" are
+ * different findings and the cards below print them differently.
+ *
+ * ## What a name that does not land does now (W7c)
+ *
+ * Three outcomes instead of one, and each of them is a sentence somebody can
+ * act on:
+ *
+ *  - **several symbols answer the name equally well**: no subject and no card,
+ *    plus {@link FactPacket.choice}, so the chat can offer the candidates. The
+ *    old behaviour took the first one and mentioned it in a note under the
+ *    answer, which is a choice made for the reader in a place they read last.
+ *  - **the name reaches nothing and a symbol is in focus**: the focus becomes
+ *    the subject and {@link FactPacket.focusFallback} says so. The user
+ *    screenshot behind this cycle showed a ready model, a focused symbol and a
+ *    refusal, all at once.
+ *  - **the name reaches nothing and nothing is in focus**: the agreed sentence,
+ *    unchanged. That is the one case where there is genuinely nothing to say.

+ * **The rules are numbered and short.** A small model follows eleven numbered

+ *
+ * **The only concrete line is a template nobody can mistake for an answer.**
+ * Every finished sentence this prompt ever carried came back in the answers
+ * verbatim, about the wrong symbols. The long note on {@link SYSTEM_PROMPT}
+ * lists all six measured attempts and what each one cost.
+ *
+ * **The cards are the whole world.** They arrive under a heading that says so,
+ * and the honest block underneath names what could not be fetched. A gap that
+ * were left out of the prompt would be a gap the model fills in itself, which is
+ * exactly the failure the citation rule exists to catch.
+ *
+ * **Thinking is switched off, per model, measured rather than assumed.**
+ * {@link nonThinkingFor} says how, and the measurements behind it are in the
+ * table on that function. Every one of the six candidates was asked the same
+ * question against the running llama-server before this table was written.

+/**
+ * What the answer must look like, in the model's own second person.
+ *
+ * Every rule below is here because a candidate broke it in a measured run, and
+ * the note says which. None of them is general prompt wisdom; the eval passes
+ * that produced them are recorded in tools/eval-llm.mjs under `ITERATIONS`.
+ *
+ *  - **Rule 3** (no heading, no closing line) came from models that wrote "The
+ *    symbols that call listUsers are:" and "No other symbol is mentioned." Both
+ *    are lines with no card behind them, so both are violations, and both were
+ *    the model being helpful rather than the model being wrong.
+ *  - **Rule 5** (copy names exactly) came from `userCreate`, which one model
+ *    wrote where the card said `createUser`. A rule against inventing behaviour
+ *    did not read as a rule against re-spelling a name.
+ *  - **Rule 6** (never repeat a line) and the repeat penalty in the chat client
+ *    came from four answers that degenerated into one sentence repeated until
+ *    the token ceiling cut it in half.
+ *  - **Rule 9** (answer only what was asked) came from an answer that listed
+ *    every card it had been given, callers and callees alike, for a question
+ *    about callers.
+ *
+ * ## The one concrete line, and the five versions of it that failed
+ *
+ * The template above the rules is the only finished-looking line in this
+ * prompt, and rule 2 exists to stop even that from being copied. It reads as it
+ * does because five earlier versions were measured and rejected:
+ *
+ *  1. a worked example built from the demo fixture's own names: the smaller
+ *     candidates put `createUser is called by registerUserRoutes` into answers
+ *     about entirely different symbols, citations and all;
+ *  2. the same example with placeholder names: they copied
+ *     `alphaWorker is called by betaHandler at line 12 [K1]` verbatim;
+ *  3. no example at all, the shape stated only as a rule: citation compliance
+ *     fell from 0.84 to 0.23, because with no shape to follow they copied the
+ *     shape of the cards and wrote `K2: registerUserRoutes ...`, where the
+ *     number is not a citation;
+ *  4. the labels named inside a sentence ("[K1], [K2] and so on") instead of a
+ *     template: 0.36 citation compliance, because fluent prose with no trailing
+ *     bracket is the easier continuation of a sentence;
+ *  5. the fallback sentence quoted in full in rule 7: models appended
+ *     `No card covers this. Fetch it with @name.` to answers that had four
+ *     perfectly good cited lines above them. It is now described, not quoted,
+ *     and the checker recognises the fallback by its marker in either language.
+ *
+ * What makes the sixth version work is not in this file at all: {@link renderCard}
+ * labels every card `[K1]`, `[K2]`, in the exact syntax a citation uses, so the
+ * cheapest possible continuation of the card list is already a compliant
+ * citation. The template only has to point at that.

+/**
+ * Which question was asked, decided without a model.
+ *
+ * This is the first half of the context compiler and the reason the rest of it
+ * can be cheap: the graph does the thinking, the model only phrases. A question
+ * is sorted into one of eight classes by its shape, by the symbols it names, by
+ * what the reader is looking at and by which mode is open. No inference, no
+ * embedding, no round trip; the same words always land in the same class, which
+ * is what makes the recipes below it reproducible and the eval comparable.
+ *
+ * ## Three rules hold the whole file up
+ *
+ * **The order of the rules is the answer.** A question can carry the words of
+ * two classes ("Was passiert, wenn validateUser wirft?" is both a what-if and a
+ * why-error), so the patterns are tried in a fixed order and the first match
+ * wins. That order is written down in {@link CLASS_RULES} and is part of the
+ * contract, not an accident of how the array was typed.
+ *
+ * **A subject is found, never guessed.** The symbol a recipe centres on comes
+ * from an explicit `@mention`, else from a name in backticks or quotes, else
+ * from an identifier-shaped word (camelCase or dotted), else from what the
+ * reader has in focus. Where it came from travels with it in
+ * {@link Classification.subjectFrom}, because "you asked about this" and "you
+ * were looking at this" are different claims and the panel says which one it
+ * is. A word that is only a word yields no subject at all.
+ *
+ * **`other` is a real answer.** A question that matches nothing and names
+ * nothing is `other`, and the recipe for it says so instead of quietly
+ * answering a different question. Falling back to `what-is` on the FOCUS would
+ * be the compiler inventing the question, and it still does not happen.
+ *
+ * ## The one fallback there is, and where its line runs
+ *
+ * The independent audit of 2026-08-29 asked "How many times was createUser
+ * called at runtime?" and got `other` with zero cards. The product stayed
+ * honest about it, but a question that spells out a symbol and gets nothing is
+ * a recall failure and not a virtue: the reader named the thing they wanted
+ * facts about. So a question with no matching rule and no mode now falls back
+ * to `what-is` WHEN IT NAMED A SYMBOL ITSELF, through a mention, quotes or an
+ * identifier-shaped word, and the rule that fired says
+ * {@link SUBJECT_FALLBACK_RULE} so the panel can show where the answer came
+ * from.
+ *
+ * The line runs exactly at `subjectFrom`. A named subject is the reader's own
+ * word and asking "what is it" about it answers a question they did ask, in
+ * the weakest form the compiler has. A focus subject is what they were looking
+ * at a minute ago, and turning that into a question would be the invention the
+ * rule above forbids. So "Welche Datenbank benutzt insert?" stays `other`: the
+ * lowercase `insert` is a word, not a symbol shape, and this file will not
+ * fetch the facts of whatever the index happens to have called `insert` and
+ * present them as an answer.

+/**
+ * From a name somebody typed to the symbol the index knows.
+ *
+ * The classifier answers "which symbol is this question about" with a string,
+ * because that is all a sentence carries. Every recipe below needs a
+ * {@link SymbolRef}: a file, a range, and the `nodeId` that says the index
+ * really holds this symbol. This file is the one bridge between the two, and it
+ * is the same bridge the bug wizard's `resolveHop` crosses, for the same reason:
+ * publishing a reference the index never confirmed would tell the rest of the
+ * product that a perfectly well indexed symbol is not indexed.
+ *
+ * Three rules:
+ *
+ * **The index decides, not the string.** A name is searched, the hits are
+ * filtered by how well they answer the name, and the winner is resolved at its
+ * declaration line so the reference carries the range the index has. A name the
+ * index does not hold resolves to nothing, which is a finding the recipe
+ * reports rather than an error it throws.
+ *
+ * **A qualified suffix beats a bare name.** `userService.create` and `create`
+ * both name something; the first one names less. So a candidate whose qualified
+ * name ends with the requested dotted path wins over one that merely carries
+ * the same last segment, and an exact bare-name match beats a substring hit.
+ *
+ * **Ambiguity is reported, not resolved by luck.** Two symbols named `create`
+ * live in this project's own fixture on purpose. When several candidates tie,
+ * the first in a deterministic order is returned and the others travel with it
+ * in {@link ResolvedSubject.alternatives}, so a card can say that the name was
+ * ambiguous instead of quietly picking one.
+ *
+ * ## How a reader spells a name, and why that stopped deciding (W7c)
+ *
+ * A user wrote `@createuser explain this funktion`. The search overlay showed
+ * `createUser` in src/services/userService.ts on the same screen, and the chat
+ * answered "the index holds no symbol called 'createuser'". Two readings of one
+ * index contradicting each other in one window is the worst kind of wrong: the
+ * product proves against itself that it knows the symbol.
+ *
+ * The cause was here. The comparisons below were letter for letter, while the
+ * server search behind BOTH surfaces is BM25 over a camelCase-splitting index
+ * and returns `createUser` for `createuser` without hesitating. So the hit was
+ * fetched, scored zero and thrown away.
+ *
+ * Since W7c the comparison is folded, and the spelling became the FIRST rank
+ * instead of a filter:
+ *
+ *  1. a hit matched with the exact spelling beats one matched by folding,
+ *  2. within that, the specificity ladder of the three rules above decides,
+ *  3. then non-test before test,
+ *  4. then ordinal by qualified name.
+ *
+ * Nothing else moved: the same search, the same limit, the same deterministic
+ * order. A name the index really does not hold still resolves to nothing.

+ *
+ * Zwei verschiedene Loesungen, weil die beiden Aufrufstellen verschieden sind:

+ *   ueber das LAN geoeffnetes UI aber nicht mehr. Ohne Fallback waere dort
+ *   ploetzlich jeder snippetHash weg, und eine fehlende Invalidierung faellt
+ *   niemandem auf, bis der Cache falsch antwortet.
+ * - `sha1Hex` ist synchron, weil `generateChecklist` synchron und rein ist.
+ *   Es asynchron zu machen hiesse, die Reinheit der einen Funktion aufzugeben,
+ *   deren Ids in `understanding.json` landen.

+ *     the difference between "no results" and "nobody looked".

+ * A tour is about the repository: it says which file has to make sense before
+ * another one can, and that answer is the same for everybody who checks the

+ * **Nothing in a stored tour names a machine.** No absolute path, no `file://`

+ * the index resolved one, a qualified name; the URI a reader's editor opens is
+ * built at the moment it is asked for. That is why there are two shapes below
+ * rather than one: the record is what would be on disk, the DTO is what a
+ * surface receives with the URIs filled in.
+ *
+ * **Nothing in a stored tour is a clock reading.** No generation timestamp, no
+ * "last generated at". Two runs of the generator over one index produce
+ * byte-identical documents, which is what makes a regenerated tour a diff a

+ * in this file is on the progress record, which is per reader and is the only
+ * thing here anybody would want a clock for.

+ * Die Agentenebene: kleine leuchtende Koerper, die den Knoten umkreisen, an dem
+ * ein Agent gerade arbeitet, und die zum naechsten FLIEGEN statt dorthin zu
+ * springen.
+ *
+ * ## Warum eine eigene Ebene und keine Umfaerbung
+ *
+ * Weil die Farben dieses Graphen schon etwas bedeuten. Die Knoten sind
+ * Sternklassen nach ihrem Grad, die Kanten tragen seit W9 zwoelf
+ * unterscheidbare Arten, und die Legende erklaert beides. Einen Knoten
+ * umzufaerben, weil gerade jemand daran arbeitet, hiesse, eine Aussage ueber
+ * die Struktur durch eine ueber die Gegenwart zu ersetzen: der Leser saehe
+ * einen Stern der falschen Klasse und wuesste nicht, dass er es tut. Diese
+ * Ebene legt sich DARUEBER und laesst jedes Pixel des Graphen, wie es war.
+ *
+ * ## Warum die Koerper DOM sind und keine Geometrie
+ *
+ * Dieselbe Entscheidung wie beim Ring der Hierarchie-Ansicht (Entscheidung 9 im
+ * Kopf von GalaxyPanel.tsx), und hier kommt ein zweiter Grund dazu: die Groesse
+ * steht im Contract in PIXELN (8 bis 12). Ein Objekt in der Szene hat eine
+ * Groesse in Welteinheiten, und wie viele Pixel daraus werden, entscheidet die
+ * Kamera. Ein DOM-Element ist genau so gross, wie es gross sein soll, und es
+ * traegt seinen Buchstaben lesbar daneben, was eine Kugel von zehn Pixeln nicht
+ * kann.
+ *
+ * Bewegt wird trotzdem in der Szene: das `group`, in dem der Koerper haengt,
+ * bekommt in jedem Bild seine Position, und das DOM-Element folgt der
+ * Weltmatrix. Ein Umweg ueber den React-Zustand waere ein Neurendern des Baums
+ * bei jedem Bild.
+ *
+ * ## Was die vier Arten unterscheidet, und woran man es sieht
+ *
+ *  - **lesen**: weiter Orbit, ruhig. Ein Agent, der liest, geht nicht an eine
+ *    Stelle, er sieht sich um.
+ *  - **schreiben**: enger Orbit, schneller. Er ist AN der Stelle.
+ *  - **suchen**: weiter Orbit, und dazu kurze Pings an den Knoten, deren NAME
+ *    das Suchmuster traegt. Was eine Suche wirklich gelesen hat, weiss dieses
+ *    Fenster nicht; was es weiss, ist, welche Symbole so heissen, und genau das
+ *    zeigen die Pings.
+ *  - **testen**: eine gestrichelte Linie zum geprueften Bereich, wenn der
+ *    Befehl eine Datei nennt, die der Index kennt. Nennt er keine, gibt es
+ *    keine Linie, und das Instrument sagt warum.
+ *
+ * ## Was W11b dazugelegt hat, und die eine Regel dahinter
+ *
+ * **Jede Bewegung hier ist ein Ereignis.** Nichts bewegt sich, weil die Uhr
+ * laeuft.
+ *
+ *  1. **Der Flug.** Wechselt der Ort eines Akteurs, faellt sein Koerper nicht
+ *     an die neue Stelle, er fliegt in {@link TRANSITION_MS} Millisekunden auf
+ *     einer gebogenen Bahn dorthin. Die Kruemmung ist nicht Zierde: an einer
+ *     Geraden sieht man nicht, in welche Richtung geflogen wurde, und zwei
+ *     Fluege zwischen denselben Symbolen zeichnen dieselbe Strecke. Hinter dem
+ *     Koerper laeuft ein kurzer Schweif nach, der sagt, wie schnell es ging.
+ *  2. **Die Spur.** Die zuletzt besuchten Knoten bleiben gestrichelt
+ *     verbunden stehen, UNTER den echten Kanten des Graphen und in der Farbe
+ *     des Akteurs. Sie ist der Unterschied zwischen "folgt einem Aufrufpfad"
+ *     und "springt quer durch das Repository", und sie ist gestrichelt und
+ *     tieferliegend, damit sie nie fuer eine Beziehung im Code gehalten wird.
+ *     Die Legende sagt denselben Unterschied noch einmal in Worten.
+ *  3. **Der Puls.** Der Koerper atmet im Takt der Ereignisse dieses Akteurs:
+ *     viele in der letzten Minute ergeben einen schnellen, kraeftigen Puls,
+ *     wenige einen langsamen, schwachen, keine gar keinen. In einem Bild mit
+ *     tausenden leuchtenden Knoten ist ein weiterer leuchtender Punkt kein
+ *     Unterschied; ein Punkt, der atmet, ist einer. Und weil der Takt die
+ *     gezaehlten Ereignisse SIND, ist der Puls selbst eine Auskunft und keine
+ *     Dekoration.
+ *  4. **Die Welle.** Ein Schreib-Bruch (mehrere Aenderungen am selben Knoten in
+ *     kurzer Folge) erzeugt GENAU EINE konzentrische Welle. Eine je Ereignis
+ *     waere Dauerfeuer, und Dauerfeuer sagt nichts.
+ *  5. **Die Ruhe.** Ein Akteur ohne Ereignis seit einer Minute haelt an: kein
+ *     Orbit, kein Puls, keine Pings, blass. Er verschwindet nicht, denn sein
+ *     Lauf laeuft. Das ist AC6 dieses Zyklus, und es ist die Bedingung dafuer,
+ *     dass die vier Punkte darueber ueberhaupt etwas bedeuten.
+ *
+ * ## Die Nahtstellen fuer den Beweislauf
+ *
+ * {@link agentAngles} traegt den Winkel jedes Koerpers, {@link agentPositions}
+ * seine Weltposition, {@link agentMotion} die aufgezeichneten Punkte des
+ * letzten Fluges, {@link agentTails} die Zahl der Schweifpunkte,
+ * {@link agentCamera} die Lage der Kamera. Alle fuenf sind LESUNGEN aus dem
+ * Bild, das gerade gezeichnet wurde, und keine zweite Rechnung daneben: was der
+ * Beweislauf misst, ist genau die Zahl, die den Koerper bewegt hat.

+ *  - Die Prop `targetNodes` bleibt erhalten: sie bediente im
+ *    Original die Kanten zwischen zwei Galaxien. Dieses Projekt setzt sie
+ *    nicht, sie bleibt aber stehen, damit die Datei gegen das Original
+ *    vergleichbar bleibt.
+ *  - EDGE_TYPE_COLORS und DEFAULT_EDGE_COLOR bleiben exportiert (W4d);
+ *    seit der gemeinsamen Kantenpalette kommen sie aus graph/edge-style.
+ *  - W9, Aenderung 1: die Deckkraft haengt an der Kantenzahl, statt fest zu
+ *    sein. Die Zahlen und der Grund stehen an {@link edgeIntensityFor}. Ab
+ *    30000 Kanten rechnet weiter die Kurve der Uebernahme, Zeichen fuer
+ *    Zeichen; darunter wird die Kante so hell, dass ihre Farbe eine Aussage
+ *    ist.
+ *  - W9, Aenderung 3: eine Kante darf einen seitlichen Versatz tragen
+ *    (`GraphEdge.offset`), damit zwei Beziehungen zwischen denselben zwei
+ *    Symbolen nicht auf demselben Strich liegen. Ohne den Wert aendert sich
+ *    nichts; die Galaxie setzt ihn nicht.
+ *  - W9, Aenderung 2 ergaenzte die Engine-Kantenarten. Die gemeinsame
+ *    Palette traegt diese Arten jetzt fuer alle Graphansichten.
+ *  - Ein GPU-Puls laeuft entlang gerichteter Kanten von Quelle zu Ziel.
+ *    Geometrie und Material bleiben gebuendelt; nur eine Zeit-Uniform wird

+ * geblendeter Linien, die sonst zu einem weissen Schleier verschmelzen. Fuer
+ * ein Projekt mit 178 Kanten sind sie zu vorsichtig; dort ist das Ergebnis ein
+ * gleichmaessig blasser Nebel, in dem zwoelf Farben wie eine aussehen
+ * (Martins Befund vom 2026-08-29).
+ *
+ * Also haengt die Deckkraft jetzt an der Kantenzahl. Die Kurve in Zahlen:
+ *
+ *   Kanten | innerhalb   | ausserhalb  | vorher (innerhalb / ausserhalb)
+ *   -------|-------------|-------------|--------------------------------
+ *      178 | 0.62        | 0.30        | 0.25   / 0.06
+ *     2000 | 0.62        | 0.30        | 0.25   / 0.06
+ *     8000 | 0.206       | 0.070       | 0.140  / 0.034
+ *    30000 | 0.0722      | 0.0173      | 0.0722 / 0.0173
+ *   120000 | 0.0361      | 0.0087      | 0.0361 / 0.0087
+ *
+ * Zwei Eigenschaften, auf die es ankommt:
+ *
+ * 1. **Ab 30000 Kanten aendert sich nichts.** Dort und darueber rechnet weiter
+ *    genau die Kurve der Uebernahme (`edgeIntensityScale` aus density.ts, mal
+ *    den urspruenglichen 0.25 beziehungsweise 0.06). Ein grosses Repository
+ *    wird durch diese Aenderung um keinen Hauch heller, und die Wand, gegen die
+ *    die Uebernahme gebaut ist, bleibt verhindert.
+ * 2. **Dazwischen wird geometrisch interpoliert**, in log(Kantenzahl). Das ist
+ *    stetig an beiden Enden, monoton fallend, und es gibt keinen Punkt, an dem
+ *    das Bild springt.
+ *
+ * Der Fokus-Zweig bleibt, wie er war (0.5 fuer die markierte Nachbarschaft,
+ * 0.04 mal Dichte fuer den Rest). Er beantwortet eine andere Frage als diese
+ * Kurve: nicht "welche Art ist das", sondern "was gehoert zu dem, was ich
+ * gerade angesehen habe". Ihn mit anzuheben hiesse, den Kontrast wegzunehmen,
+ * der eine Auswahl ueberhaupt sichtbar macht.

+/**
+ * Die Galaxie als Panel, und der Fokus, der in beide Richtungen laeuft.
+ *
+ * Die Szene selbst ist uebernommen (src/galaxy/GraphScene.tsx, MIT, DeusData);
+ * diese Datei ist das, was dieses Projekt daraus macht. Sie haelt fuenf
+ * Entscheidungen, und jede davon ist eine Antwort auf eine Frage, die man beim
+ * Lesen sofort stellt:
+ *
+ * 1. **Das Panel laedt selbst.** Nicht die App: `/api/layout` ist die einzige
+ *    Route, die dieses Panel braucht, und niemand sonst im Haus braucht sie.
+ *    Ein Fehler wird gezeigt, nicht verschluckt (src/galaxy/layout-source.ts).
+ *    Was geladen wurde, meldet das Panel nach oben (`onLayout`), weil die
+ *    Bedeutungssuche daraus ihre Fan-in-Zahlen nimmt und der Server sie in der
+ *    flachen Suchform nicht mitschickt.
+ * 2. **Einmal sichtbar heisst gemountet.** Wird das Panel zugeklappt, bleibt
+ *    die Szene im Baum und nur der Renderloop steht still (`active`). Ein
+ *    Aushaengen wuerde den WebGL-Kontext wegwerfen, und der naechste Aufklapper
+ *    zahlte dafuer mit Sekunden und einem schwarzen Kasten.
+ * 3. **Die Kamera faehrt bei neuer Objekt-Identitaet.** So ist der
+ *    CameraAnimator der Uebernahme gebaut: `useEffect([target])`. Also wird
+ *    fuer jede Fahrt ein frisches Ziel gerechnet, auch wenn es zweimal
+ *    dasselbe Symbol ist, und der Zaehler `targetChanges` im Testgriff zaehlt
+ *    genau diese frischen Ziele.
+ * 4. **Ein Symbol ohne Knoten sagt das.** Der Deckel liegt bei 5000 Knoten;
+ *    was darueber liegt, ist nicht im Bild. Ein stiller No-op waere die
+ *    Behauptung, das Symbol sei gezeigt worden.
+ * 5. **Unter dem Kopf steht, was man sieht.** Die Legende (W4d, Nutzerfeedback)
+ *    erklaert Knotenfarbe, Knotengroesse, Kantenfarben, Fokus und Positionen,
+ *    und zwar aus den Quellen, die sie erzeugen: src/galaxy/galaxy-legend.ts.
+ *    Sie ist auf- und zuklappbar, weil dieses Panel 420 Pixel hoch ist und ein
+ *    Leser, der die Erklaerung gelesen hat, den Platz wiederhaben will; der
+ *    Zustand liegt im localStorage, damit die Entscheidung den Reload
+ *    ueberlebt.
+ *
+ * Seit W4e zeigt dasselbe Panel zwei Bilder, und daraus kommen vier weitere
+ * Entscheidungen:
+ *
+ * 6. **Ein Canvas, zwei Datensaetze.** Der Chip-Schalter tauscht die Daten der
+ *    Szene und nicht die Szene. Ein zweites `<Canvas>` waere ein zweiter
+ *    WebGL-Kontext, und ein bedingtes Aushaengen waere derselbe schwarze
+ *    Kasten wie in Entscheidung 2, nur bei jedem Umschalten.
+ * 7. **Die Hierarchie ist die Vorgabe, sobald es einen Walk gibt.** Wer sich
+ *    fuer einen Einstiegspunkt entschieden hat, hat eine Frage nach der Tiefe
+ *    gestellt, und die Wolke beantwortet sie nicht. Ein Klick auf `galaxy`
+ *    holt das alte Bild zurueck, und diese Wahl haelt die Sitzung: sie ist
+ *    eine Antwort und keine Geste. Ohne Walk gibt es nichts zu projizieren,
+ *    also steht der Schalter dann auf `galaxy` und der andere Chip sagt, was
+ *    ihm fehlt.
+ * 8. **Die Kamera rahmt den ganzen Subgraphen, nicht den Schritt.** Genau
+ *    darum geht es in dieser Ansicht: man soll die Tiefe SEHEN. Eine Kamera,
+ *    die bei jedem Schritt auf eine Spalte zoomt, zeigt wieder nur die
+ *    Nachbarschaft, also faehrt sie einmal je Projektion und danach bewegt
+ *    sich nur noch der Ring.
+ * 9. **Der Ring ist DOM und keine Geometrie.** Der Schritt, auf dem der Leser
+ *    steht, bekommt einen pulsenden Ring ueber seinem Punkt (`Html` aus drei
+ *    der Uebernahme, dieselbe Technik wie die Hover-Karte). Ihn aus Dreiecken
+ *    zu bauen hiesse, bei jedem Schritt die Puffer der Szene neu zu bauen und
+ *    fuer die Animation bei jedem Bild.
+ *
+ * Seit W9 ist die Legende auch der Filter, und daraus kommen zwei weitere:
+ *
+ * 10. **Gefiltert wird zwischen Bild und Szene, nicht in der Szene.** Das Panel
+ *     rechnet aus der geladenen Antwort zuerst das BILD (in der Hierarchie samt
+ *     der Beziehungen, die der Index ausser den Aufrufen kennt) und reicht der
+ *     Szene davon nur die Arten weiter, die sichtbar sein sollen. Die Szene
+ *     kennt keinen Filter, die Legende zaehlt am Bild und nicht am Gefilterten,
+ *     und beide Ansichten teilen sich denselben Satz ausgeblendeter Arten:
+ *     wer in der Galaxie die Importe weggenommen hat, findet sie in der
+ *     Hierarchie nicht wieder.
+ * 11. **Der Nachbarschafts-Fokus rechnet weiter am ganzen Bild.** Ein Klick
+ *     hebt die Nachbarn eines Symbols hervor, und Nachbar ist, wen der Index
+ *     nennt, nicht wen der Filter gerade durchlaesst. Sonst waere dieselbe
+ *     Frage je nach Filterlage anders beantwortet, ohne dass die Antwort das
+ *     sagt.
+ * 12. **Die Legende zeigt ihre Kante.** Der Kasten ist niedriger als sein
+ *     Inhalt, und der Bildlauf dieser Plattform ist eine ueberlagernde Leiste,
+ *     die im Ruhezustand nicht zu sehen ist. Ohne einen eigenen Hinweis endet
+ *     der letzte sichtbare Satz darum an einer harten Kante mitten im Wort, und
+ *     das liest sich als Fehler und nicht als Fortsetzung. Das Panel misst
+ *     deshalb selbst, ob ueber oder unter dem Kasten noch etwas steht, und sagt
+ *     es: ein Verlauf loest die Kante auf, eine Marke nennt die Richtung.
+ *
+ * Seit W11a liegt eine dritte Ebene ueber demselben Canvas, und daraus kommen
+ * drei weitere Entscheidungen:
+ *
+ * 13. **Die Agentenebene faerbt nichts um.** Sie haengt als `overlay` in
+ *     derselben Szene und legt eigene Koerper ueber die Punkte; kein Knoten und
+ *     keine Kante aendert dabei ihre Farbe. Warum das die einzige vertretbare
+ *     Form ist, steht im Kopf von src/galaxy/AgentLayer.tsx.
+ * 14. **Verortet wird HIER, weil hier das Layout liegt.** Ein Ereignis nennt
+ *     einen Pfad und manchmal Zeilen; welcher Knoten das ist, weiss nur, wer die
+ *     Layout-Antwort hat. Die Rechnung steht in src/agents/agent-view.ts und
+ *     wird EINMAL gemacht: die Ebene zeichnet aus demselben Ergebnis, aus dem
+ *     das Instrument seine Zeilen schreibt.
+ * 15. **Der Leser ist ein Akteur wie die anderen.** Oeffnet er ein Symbol,
+ *     entsteht hier ein Ereignis mit dem Namen "you", das durch dieselbe Ebene
+ *     laeuft. Es geht NICHT in die Ereignisdatei: die Bruecke hat keine Route,
+ *     die etwas entgegennimmt, und dieses Ereignis verlaesst das Fenster nie.
+ *
+ * Seit W10b kommen drei Entscheidungen aus vier Nutzerbefunden dazu:
+ *
+ * 16. **Die beiden Ansichts-Knoepfe klappen auch.** Ein Klick auf den AKTIVEN
+ *     Knopf klappt die Sektion zu, ein Klick bei zugeklappter Sektion klappt sie
+ *     auf und waehlt diese Ansicht. Das ist die Antwort auf den Befund "galaxy
+ *     Knopf macht nichts" (2026-08-29) und auf den Auftrag vom Folgetag: "die
+ *     beiden Buttons unten links sollten auch aufklappen und zuklappen koennen."
+ *     Der beschriftete Ein- und Ausklapper daneben bleibt, und beide Wege gehen
+ *     durch DENSELBEN Rueckruf: zwei Wege in denselben Zustand duerfen nicht
+ *     zwei Zustaende ergeben.
+ * 17. **Die Hierarchie waechst auch aus dem Fokus, waehlt sich aber nicht
+ *     selbst.** Bis W10b gab es sie nur nach einem Einstiegs-Spaziergang, und
+ *     ein Leser mit einem Symbol vor sich sah einen grauen Knopf (Befund
+ *     2026-08-30). Der Walk aus dem Fokus kommt von aussen (`focusWalk`), weil
+ *     nur die App einen Provider hat; er hat denselben Vorwaerts-Closure und
+ *     dieselben Grenzen. Die VORGABE bleibt trotzdem die Galaxie: ein Fokus
+ *     entsteht bei jedem Klick in den Code, und eine Ansicht, die dabei von
+ *     selbst umschaltet, waere ein Bild, das der Leser nie bestellt hat. Der
+ *     Kopf sagt, woher die Wurzel kommt.
+ * 18. **Die Kamera passt das Bild ein, sofort und nicht im Anflug.** Beim
+ *     Oeffnen, beim Aufklappen, bei einer neuen Groesse der Zeichenflaeche und
+ *     auf Knopfdruck steht sie senkrecht auf der groessten Flaeche der Wolke,
+ *     weit genug weg, dass JEDER Knoten im Bild liegt (src/galaxy/camera-frame.ts).
+ *     Ohne Anflug, weil eine Einpassung keine Bewegung ist, sondern die Lage, in
+ *     der das Bild anfaengt. In der Hierarchie bleibt es bei der frontalen
+ *     Rahmung aus W5c: sie ist eine flache Zeichnung mit Spalten, und eine
+ *     Kamera, die deren Hauptachsen folgt, stellte das Raster schief.

+ * MIT License. Copyright (c) 2025 DeusData.
+ *
+ * Uebernommen am 2026-08-28 aus DeusData/codebase-memory-mcp, Branch
+ * feat/atlas-r1, Datei graph-ui/src/components/GraphScene.tsx. Der Lizenztext
+ * und die Liste aller uebernommenen Dateien stehen in THIRD_PARTY.md.
+ *
+ * Aenderungen gegenueber dem Original:
+ *  1. IdleAutoRotate suchte seinen Canvas per Dokumentabfrage nach dem
+ *     Element-Namen und traf damit den ERSTEN Canvas des Dokuments, nicht den
+ *     eigenen. In dieser Anwendung steht Monaco daneben, also greift die
+ *     Szene jetzt ihren eigenen Canvas ueber useThree().gl.domElement, so wie
+ *     es der ApproachWatcher des Originals schon tat.
+ *  2. sceneRadius lief als IIFE bei jedem Render ueber alle Knoten. Jetzt in
+ *     useMemo([data.nodes]): das Layout kommt fertig vom Server, der Radius
+ *     aendert sich also genau dann, wenn die Knoten sich aendern.
+ *  3. Der Satelliten-Zweig fuer data.linked_projects ist gestrichen. Die
+ *     Coverage-Ebene ist getrennt wiederhergestellt, mit eigenen Render-IDs,
+ *     Auswahl-Callbacks und Kamera-Grenzen fuer beide Wolken.
+ *  4. ApproachWatcher (Semantic Zoom) und ViewTargetReporter (Minimap-Feed)
+ *     sind gestrichen, samt der Props onApproachNode und onViewTarget. Beide
+ *     bedienen Panels, die dieses Projekt nicht uebernimmt.
+ *  5. NodeTooltip war die einzige Tailwind-Abhaengigkeit der Uebernahme. Der
+ *     Import ist weg; `renderTooltip` ist damit der einzige Weg zu einer
+ *     Hover-Karte, und ohne die Prop zeigt die Szene keine. Die Karte dieses
+ *     Projekts steht in NodeTooltipCard.tsx.
+ *  6. Der Typ-Import von OrbitControlsImpl kommt weiter aus three-stdlib
+ *     (hier als devDependency gefuehrt), React-Typen werden explizit
+ *     importiert statt ueber den globalen React-Namensraum gelesen.
+ *  7. Formatierung an den Stil dieses Projekts angeglichen (4 Leerzeichen,
+ *     einfache Anfuehrungszeichen). Kein Verhalten haengt daran.
+ *  8. Neu (W4e): die Prop `overlay`. Sie haengt einen beliebigen Knoten in die
+ *     Szene, ohne dass die Szene wissen muss, was er zeigt. Gebraucht wird sie
+ *     fuer den Ring um den Schritt, auf dem der Leser in der Hierarchie-Ansicht
+ *     steht: ein Ring als Geometrie waere ein Neubau der Puffer bei jedem
+ *     Schritt, und eine Animation davon einer bei jedem Bild. Ohne die Prop
+ *     zeigt die Szene nichts zusaetzlich, also aendert sie den Galaxie-Modus
+ *     nicht.
+ *  9. Neu (W5c): die drei Label-Props `labelWorldFontSize`,
+ *     `labelMaxTextWidth` und `onLabelLayout`. Sie werden unveraendert an
+ *     NodeLabels durchgereicht; ohne sie zeichnet die Ebene wie das Original.
+ *     Warum es sie gibt, steht im Kopf von NodeLabels.tsx.
+ * 10. Neu (W10): vier Props fuer das, was Rechenzeit kostet, und was jede
+ *     davon aendert:
+ *      - `projection`: `flat` stellt eine orthografische Kamera von oben und
+ *        nimmt den OrbitControls das Drehen. Schwenken und Zoomen bleiben.
+ *      - `drawEdges`: `false` haengt die Kantenebene GAR NICHT ein. Ihre
+ *        Helligkeit auf null zu setzen waere derselbe Rechenaufwand mit einem
+ *        unsichtbaren Ergebnis, und ein Schalter, der spart, muss sparen.
+ *      - `labelDistanceFactor`: Namen nur innerhalb dieses Vielfachen des
+ *        Szenenradius. Bis W10 haengt die Sichtbarkeit rein an der
+ *        Knotengroesse; die Kamera kam darin nicht vor.
+ *      - `frameCap`: mit einem Deckel faehrt der Canvas mit
+ *        `frameloop="never"` und wird von einem eigenen rAF-Takt bewegt.
+ *        OHNE Deckel bleibt es bei `always`, also bei genau dem Renderloop,
+ *        den die Beweislaeufe bis W9 gemessen haben.
+ *     Dazu der Bildratenzaehler, der die Naht `globalThis.__atlasGalaxyPerf`
+ *     fuellt (src/galaxy/frame-rate.ts). Er ist die EINZIGE Messung: das
+ *     Panel liest denselben Wert, den er schreibt.
+ * 11. Geaendert (W10): CameraAnimator zaehlt seinen Fortschritt nach der
+ *     verstrichenen Zeit und nicht mehr je Bild. Bis dahin stand dort
+ *     `progress.current += 0.02`, also fuenfzig Bilder bis ans Ziel; unter
+ *     einem Bildratendeckel von 30 waere derselbe Anflug doppelt so lang
+ *     gewesen. Bei 60 Bildern je Sekunde ist die Bewegung dieselbe wie vorher.
+ * 12. Neu (W10b): ein Kameraziel darf eine Oben-Richtung mitbringen (`up`) und
+ *     SOFORT gelten (`immediate`), und die Szene meldet an
+ *     `globalThis.__atlasGalaxyFit`, wo ihre Knoten wirklich im Bild liegen.
+ *     Alle drei gehoeren zur Einpassung aus AC5 und zu nichts sonst:
+ *      - `up`, weil die eingepasste Ansicht senkrecht auf der groessten Flaeche
+ *        der Wolke steht und dafuer eine eigene Oben-Richtung braucht
+ *        (src/galaxy/camera-frame.ts). Ohne sie waere die Ausrichtung eine
+ *        halbe: die Kamera stuende richtig und das Bild waere verdreht.
+ *      - `immediate`, weil eine Einpassung keine Fahrt ist. Sie ist die Lage,
+ *        in der ein Bild anfaengt, und ein Anflug darauf waere eine Bewegung
+ *        ohne Aussage, die ausserdem jede Messung von einer Wartezeit abhaengig
+ *        machte. Die Anfluege auf ein Symbol bleiben Anfluege.
+ *      - die Naht, weil AC5 am BILD bewiesen wird und nicht an der Absicht: nur
+ *        wer die Kamera hat, kann sagen, wo ein Knoten auf dem Schirm landet.
+ * 13. Neu (W11b): ein Kameraziel darf mit einer kritisch gedaempften Feder
+ *     angefahren werden (`spring`). Nur die FOLLOW-Kamera der Agentenebene
+ *     benutzt es, und nur sie braucht es: sie bekommt waehrend eines Anflugs
+ *     ein neues Ziel, und der Anflug oben faengt bei jedem neuen Ziel wieder
+ *     bei null an, was genau der Ruck ist, den AC3c verbietet. Die Feder traegt
+ *     ihre Geschwindigkeit ueber das neue Ziel hinweg; ihr Daempfungsgrad ist
+ *     genau 1, sie kann also nicht ueberschwingen. Ohne das Feld ist jeder
+ *     bestehende Anflug Zeichen fuer Zeichen der von vorher.
+ * 14. Neu (Review-Call 2026-10-02): CameraAnimator spielt einen Anflug, der
+ *     schon vor dem Aufsetzen der Szene gesetzt war, nicht nach. Er gehoert
+ *     zum Bild davor; eine Einpassung gilt weiter.
+ * 15. Neu (Review-Call 2026-10-02): `FitContainment` rahmt das naechste Bild
+ *     eines Scopes, ohne neu einzupassen: die Kamera tritt entlang ihrer
+ *     Blickrichtung zurueck oder vor, solange der Leser sie nicht bewegt hat.
+ * 16. Neu (Review-Call 2026-10-02): die OrbitControls zoomen zum Mauszeiger
+ *     (`zoomToCursor`), nicht mehr in die Bildmitte.
+ * 17. Neu (Review-Call 2026-10-02): die Prop `rootIds`. Die Wurzeln eines
+ *     Scopes bekommen einen Ring und einen Namen, der immer zu sehen ist, und
+ *     die Trennung auf dem Schirm schiebt sie nie weg. Ohne die Prop zeichnet
+ *     die Szene wie vorher.
+ * 18. Neu (Review-Call 2026-10-02): die Prop `path`. Ein Pfad oder eine
+ *     Aufrufreihe liegt mit beschrifteten Kanten ueber der Szene
+ *     (src/galaxy/PathLayer.tsx). Ohne die Prop zeichnet die Szene wie vorher.
+ * 19. Neu (Handtest K6): ein neu gezeigter Pfad rahmt die Kamera auf seine
+ *     Knoten (`PathFrame`, Rechnung in src/galaxy/path-frame.ts), mit Rand und
+ *     neben der Schrittliste. Die Knoten des Pfades bekommen ihren Namen von der
+ *     Pfadebene; die Namensebene der Szene zeichnet fuer sie keinen zweiten.
+ * 20. Neu (Handtest K12): die Namen der Wurzelmarken suchen sich freie Plaetze
+ *     um ihre Ringe (src/galaxy/marker-names.ts), statt bei mehreren Wurzeln
+ *     aufeinander zu liegen; ein Name ohne freien Platz wird ausgeblendet. Eine
+ *     einzelne Wurzel behaelt ihren Namen unter dem Ring.
+ * 21. Neu (Review zu K5): die Prop `labelIds`. Mit ihr bekommen nur diese
+ *     Knoten einen Namen (die Hierarchie eines grossen Ausschnitts benennt die
+ *     Wurzel und ihre direkten Nachbarn). Ohne die Prop wie vorher.
+ * 22. Neu (Handtest 2026-10-04, G1): die Huelle des Canvas bildet ihren
+ *     eigenen Stapelkontext (`isolation: isolate`). Siehe `CANVAS_STYLE`.
+ * 23. Neu (Review zu K29): neben der Huelle steht die Ebene der Hover-Karten,
+ *     damit eine Karte ueber den Flaechen der Galaxie steht und nicht wie die
+ *     Namen darunter. Siehe hover-layer.tsx.

+ *  - Importpfad: ../lib/types liegt hier neben der Datei.
+ *  - Formatierung an den Stil dieses Projekts angeglichen (4 Leerzeichen,

+ *  - Logik unveraendert: Textur-Bau, Kuerzung, Sprite-Groesse und die Auswahl
+ *    der bis zu 80 groessten Knoten sind die des Originals.
+ *  - Neu (W5c): die drei Props `worldFontSize`, `maxTextWidth` und `onLayout`.
+ *    Ohne sie verhaelt sich die Ebene wie das Original, also aendert sich die
+ *    Galaxie nicht. Die Hierarchie-Ansicht setzt sie, und zwar aus einem
+ *    Befund: dort haengt die Schriftgroesse eines Namens an der Knotengroesse,
+ *    die aus dem Grad im GANZEN Graphen kommt, und zwei Nachbarn in einer
+ *    Spalte konnten sich deshalb ueberlagern (Nutzerfeedback 2026-08-29,
+ *    Screenshots). Eine feste Weltgroesse plus eine Textbreiten-Grenze macht
+ *    die Beschriftung so gross wie das Raster sie erlaubt und nicht groesser.
+ *    `onLayout` meldet die wirklich gezeichneten Kaesten nach oben, damit der
+ *    Beweislauf sie messen kann, statt sie ein zweites Mal auszurechnen.
+ *  - Neu (W10): die Prop `maxDistance`. Bis dahin haengt die Sichtbarkeit eines
+ *    Namens REIN an der Knotengroesse (die groessten `maxLabels`), und die
+ *    Kamera kommt darin nicht vor: ein Name aus der Tiefe des Bildes wird
+ *    genauso gezeichnet wie einer direkt davor, mit einer eigenen Textur, einem
+ *    eigenen Material und einem eigenen Zeichenaufruf. Mit `maxDistance` fallen
+ *    die weit entfernten weg.
+ *
+ *    Sie werden AUSGEBLENDET und nicht ausgehaengt, und das ist der Grund, aus
+ *    dem die Entscheidung in einem `useFrame` steht und nicht in React: die
+ *    Entfernung aendert sich bei jeder Mausbewegung, und ein React-Durchgang je
+ *    Bild waere teurer als die Sprites, die er einspart. `visible = false`
+ *    ueberspringt den Zeichenaufruf, und die Textur bleibt liegen, damit ein
+ *    Zurueckfahren der Kamera nicht achtzig Texturen neu baut.

+ * Wie weit die Kamera stehen muss, damit ein Rechteck ganz ins Bild passt.
+ *
+ * Reine Trigonometrie, ohne three und ohne DOM, damit die eine Zahl, an der die
+ * Lesbarkeit der Hierarchie haengt, ohne Browser pruefbar ist.
+ *
+ * **Warum ueberhaupt eine eigene Rechnung.** `computeCameraTarget` der
+ * Uebernahme rahmt eine Punktwolke: es nimmt den Schwerpunkt, misst den
+ * groessten Abstand dazu und multipliziert ihn mit drei, mit einer Untergrenze
+ * von 300 Einheiten. Fuer eine Wolke aus tausend Sternen ist das richtig. Fuer
+ * einen Walk aus vier Symbolen ist es das nicht: der groesste Abstand ist dort
+ * klein, die Untergrenze greift, und die vier Punkte stehen als Briefmarke in
+ * der Mitte eines leeren Panels (Nutzerfeedback 2026-08-29, Screenshots). Diese
+ * Datei rechnet stattdessen aus dem Oeffnungswinkel und dem Seitenverhaeltnis
+ * die Entfernung, bei der das Rechteck genau hineinpasst, und legt einen Rand
+ * darum.
+ *
+ * **Warum frontal.** Die Uebernahme stellt die Kamera schraeg ueber die Wolke,
+ * und in drei Dimensionen ist das die bessere Ansicht. Die Hierarchie ist eine
+ * flache Zeichnung in der Ebene z=0; schraeg darauf zu sehen hiesse, ein Raster
+ * aus Spalten und Zeilen perspektivisch zu verziehen, damit es raeumlich
+ * aussieht. Also steht die Kamera frontal davor.
+ *
+ * **Seit W10 gibt es hier zwei Rahmungen.** {@link frameDistance} rahmt fuer die
+ * perspektivische Kamera, {@link orthographicZoom} fuer die flache Ansicht des
+ * Einstellungen-Panels. Sie stehen nebeneinander und nicht ineinander, weil die
+ * beiden Kameras nach verschiedenen Groessen fragen: die eine nach einer
+ * Entfernung, die andere nach Pixeln je Welteinheit. Eine gemeinsame Funktion
+ * haette einen Parameter, der entscheidet, welche Haelfte gilt.
+ *
+ * **Seit W10b kommt die Ausrichtung dazu.** Beide Rahmungen oben setzen voraus,
+ * dass die Kamera schon in die richtige Richtung sieht: sie rechnen eine
+ * Entfernung fuer ein Rechteck in der Ebene z=0. Das Layout des Servers ist
+ * aber dreidimensional und in den drei Richtungen verschieden weit, und eine
+ * Kamera, die die duenne Richtung entlangsieht, zeigt von einer Wolke einen
+ * Strich (Nutzerbefund 2026-08-30: "mich nervt, dass die Galaxy manchmal
+ * einfach flach ist"). {@link principalFrame} rechnet darum aus den Positionen
+ * selbst, wo die groesste Flaeche der Wolke liegt, und {@link fitCamera} stellt
+ * die Kamera senkrecht davor, weit genug weg, dass alles hineinpasst.

+/**
+ * Die Bildrate der Szene, einmal gemessen und von allen gelesen.
+ *
+ * ## Warum es diese Datei gibt
+ *
+ * AC9 des W10-Contracts verlangt, dass jede Einstellung, die Rechenzeit kostet,
+ * ihren Effekt in GEMESSENEN Zahlen nennt: Bildrate vorher, Bildrate nachher,
+ * auf dieser Maschine an derselben Szene. Damit braucht es zwei Leser fuer eine
+ * Zahl, das Panel und den Beweislauf, und genau da faengt der Fehler an, gegen
+ * den diese Datei geschnitten ist: eine zweite Rechnung fuer dieselbe Zahl waere
+ * eine zweite Wahrheit. Gemessen wird darum an einer Stelle (der Zaehler in der
+ * Szene, src/galaxy/GraphScene.tsx), abgelegt wird an einer Stelle (hier), und
+ * beide Leser lesen dasselbe Fenster.
+ *
+ * ## Was ein Fenster ist und warum es eines ist
+ *
+ * Frames werden gezaehlt und ueber {@link FRAME_WINDOW_MS} gemittelt. Die
+ * Alternative, den Abstand zwischen zwei Bildern zu nehmen, misst genau ein
+ * Bild: eine einzelne Ruckelphase (ein Garbage-Lauf, ein Fenster, das den Fokus
+ * wechselt) waere dann die Messung. Ein halbsekuendiges Fenster ist lang genug,
+ * dass eine Ausreisserzeit darin untergeht, und kurz genug, dass ein Leser, der
+ * einen Schalter umlegt, nicht wartet.
+ *
+ * ## Warum das Rauschband hier steht
+ *
+ * Weil eine Behauptung ohne Streuung keine Messung ist. Zwei Fenster derselben
+ * Szene ohne jede Aenderung unterscheiden sich auf dieser Maschine um mehrere
+ * Bilder je Sekunde; wer daraus "schneller" macht, hat das Rauschen gemessen.
+ * {@link noiseBandOf} nimmt die Spanne mehrerer Fenster OHNE Aenderung, und
+ * {@link verdictOf} nennt einen Unterschied innerhalb dieser Spanne genau das,
+ * was er ist: kein messbarer Unterschied. Das ist kein Makel des Produkts,
+ * sondern die Anforderung (AC9: "Wo eine Einstellung nichts messbar bringt,
+ * sagt das Panel genau das").
+ *
+ * ## Und wenn gar nichts gezeichnet wird
+ *
+ * Dann kommt kein Fenster an, und das ist eine Auskunft und kein Wert. Der
+ * Renderloop steht still, sobald das Panel zugeklappt ist (`frameloop="never"`
+ * in GalaxyPanel). {@link frameRateSnapshot} meldet dann `running: false`, und
+ * das Panel sagt, dass an einem stehenden Bild nichts zu messen ist, statt eine
+ * Null als Bildrate zu zeigen.

+/**
+ * Was in der Galaxie zu sehen ist, in Worten, die der Server deckt.
+ *
+ * Das Panel zeigt farbige Punkte in verschiedenen Groessen, helle und dunkle
+ * Linien und eine Kamera, die irgendwohin fliegt. Ohne Legende ist jede dieser
+ * vier Erscheinungen eine Einladung zum Raten, und Raten wird in einem
+ * Verstehens-Werkzeug schnell zu einer Behauptung ("die grossen roten sind die
+ * wichtigen"). Diese Datei sagt stattdessen, woher jede Erscheinung kommt.
+ *
+ * Drei Regeln, an die sich jeder Eintrag haelt:
+ *
+ * 1. **Nur, was der Server wirklich rechnet.** Knotenfarbe und -groesse kommen
+ *    aus cbm/src/ui/layout3d.c: die Farbe ist `stellar_color(degree)`, eine
+ *    Spektralklassen-Skala ueber den Knotengrad, die Groesse ist eine Basis je
+ *    Label plus ein Zuschlag aus dem Grad. Diese Oberflaeche faerbt keinen
+ *    Knoten selbst; sie malt, was im Layout steht.
+ * 2. **Die Kantenfarben kommen aus der Tabelle, die sie malt.** Importiert aus
+ *    graph/edge-style, wie EdgeLines.tsx. Gezeigt werden nur die Typen, die im
+ *    geladenen Layout wirklich vorkommen: eine Legende mit zwanzig Kantenarten
+ *    fuer einen Graphen mit dreien ist eine Legende fuer ein anderes Bild.
+ *    Seit W9 steht neben jeder Art ihre Zahl, GEZAEHLT in der geladenen
+ *    Antwort und nicht aus der Tabelle geraten, und die Liste ist absteigend
+ *    sortiert: die haeufigste Beziehung dieses Projekts steht oben. Der Deckel,
+ *    der die Liste frueher nach acht Arten abschnitt, ist damit weg. Er war
+ *    gegen eine zu lange Legende gedacht, dagegen hilft seit W5c der eigene
+ *    Bildlauf des Kastens, und seit W9 waere eine abgeschnittene Art eine, die
+ *    man nicht mehr ausblenden kann.
+ * 3. **Der Zustand des Kastens ueberlebt den Reload.** Wer die Legende
+ *    zuklappt, hat eine Entscheidung getroffen, und sie beim naechsten Laden
+ *    zu vergessen macht aus der Entscheidung eine Geste.
+ * 4. **Jede Ansicht bekommt ihre eigenen Saetze.** Seit W4e zeigt dasselbe
+ *    Panel zwei Bilder: die Galaxie und die Hierarchie des Vorwaerts-Walks. In
+ *    der zweiten kommen die Positionen nicht vom Server, sondern sind die
+ *    Aufruf-Tiefe. Es gibt darum zwei Saetze Eintraege und keine Formulierung,
+ *    die fuer beide passen soll.
+ * 5. **Die Kanten stehen oben, und die Saetze sind kurz.** Beides ist eine
+ *    Korrektur aus dem Beweisbild von W9: die Legende ist 75 Pixel hoch, die
+ *    zwoelf Arten dieses Fixtures brauchen davon vier Zeilen, und darunter
+ *    standen frueher fuenf Absaetze Fliesstext. Wer die Legende oeffnete, sah
+ *    darum als Erstes einen Satz ueber Knotenfarben und musste zu den Arten
+ *    scrollen, die er anklicken wollte. Seit W9-1 steht der Kanten-Eintrag
+ *    vorn: er ist der einzige, der auch ein Schalter ist, und er ist der, der
+ *    zum Bild gehoert, das dieser Zyklus geaendert hat. Die Erklaersaetze sind
+ *    dabei auf hoechstens drei Zeilen gekuerzt worden, ohne dass eine Aussage
+ *    weggefallen ist: gestrichen wurde Wiederholung, nicht Inhalt.

+/**
+ * Der Vorwaerts-Walk als Bild: eine Spalte je Aufruf-Tiefe, ab dem gewaehlten
+ * Einstiegspunkt.
+ *
+ * Die Galaxie zeigt, wo ein Symbol im ganzen Projekt liegt. Das ist eine
+ * Antwort auf "wo bin ich" und keine auf "wie tief geht das hier": im
+ * Server-Layout liegen die drei Symbole, die einander der Reihe nach aufrufen,
+ * irgendwo in einer Wolke aus tausend anderen, und die Kette dazwischen ist
+ * eine von zehntausend Linien. Diese Datei rechnet denselben Walk, den der
+ * Einstiegsmodus ohnehin schon laeuft (src/provider/closure.ts), in ein Bild
+ * um, in dem die Tiefe die Bildachse ist: die Wurzel links, was sie aufruft in
+ * der naechsten Spalte, was jene aufrufen in der uebernaechsten.
+ *
+ * Fuenf Regeln, und jede ist eine Antwort auf eine Frage, die man beim Lesen
+ * sofort stellt:
+ *
+ * 1. **Die Projektion ist rein und deterministisch.** Kein Zufallsgenerator,
+ *    kein Kraefte-Layout, keine Uhr: die Spalte ist der Hop, die Zeile ist die
+ *    ordinale Position des Namens in seiner Ebene. Zweimal dieselbe Eingabe
+ *    gibt zweimal dasselbe Bild, und zwei Leser, die dasselbe Symbol waehlen,
+ *    reden ueber dasselbe Bild. Verglichen wird ordinal und nie mit
+ *    `localeCompare`, aus demselben Grund wie im Walk selbst: zwei Maschinen
+ *    mit verschiedenen Sortierregeln sollen die Ebene nicht anders anordnen.
+ * 2. **Es wird keine Kante erfunden und keine versteckt.** Gezeichnet werden
+ *    genau die `via`-Kanten des Walks, einschliesslich der Kanten, die in ein
+ *    schon besuchtes Symbol zurueckfuehren. Genau die sind die Zyklen, und ein
+ *    Bild, das sie weglaesst, zeigt einen Baum, wo ein Graph ist.
+ * 3. **Die Grenze reist mit.** `truncated`, `cap` und die Tiefe des Walks
+ *    stehen im Ergebnis, damit die Kopfzeile sagen kann, dass hinter der
+ *    letzten Spalte noch etwas liegt. Ein Bild, das an seiner Grenze einfach
+ *    aufhoert, behauptet, dort sei das Ende des Codes.
+ * 4. **Farbe, Groesse und Label kommen vom Server, wo es sie gibt.** Sie sind
+ *    Aussagen ueber den Knotengrad im GANZEN Graphen (layout3d.c,
+ *    `stellar_color`), und die bleibt wahr, egal in welchem Bild der Punkt
+ *    liegt. Findet sich das Symbol nicht im geladenen Layout, bekommt es einen
+ *    neutralen Grauton und eine mittlere Groesse: eine gerechnete Sternfarbe
+ *    waere eine Behauptung ueber einen Grad, den diese Datei nicht kennt.
+ * 5. **Datei und Zeile kommen aus dem Walk.** Der Walk hat jedes erreichte
+ *    Symbol beim Index aufgeloest; das ist die genauere Quelle, und sie ist
+ *    auch fuer die Symbole da, die im Layout gar nicht vorkommen. Ein Klick auf
+ *    einen Knoten dieses Bildes fuehrt deshalb ueber denselben Weg wie ein
+ *    Klick in die Galaxie.
+ *
+ * Seit W9 kommt eine sechste dazu, und sie ist ausdruecklich NEBEN die
+ * Projektion gebaut und nicht in sie hinein:
+ *
+ * 6. **Die uebrigen Beziehungen werden gezeichnet, nicht gerechnet.** Was
+ *    dieselben Symbole ausser dem Aufruf noch verbindet (ein Fehlerpfad, ein
+ *    Verweis, eine Typnutzung), steht in der schon geladenen Layout-Antwort und
+ *    wird von {@link hierarchyIndexEdges} dazugelegt. Die Spalten entstehen
+ *    weiter allein aus dem Walk: {@link projectHierarchy} sieht diese Kanten
+ *    nie, kann also auch nichts nach ihnen umordnen. Das ist keine Vorsicht,
+ *    sondern die Zusicherung selbst (Regel 1): eine Beziehung, die nicht der
+ *    Aufruf ist, darf die Aufruf-Tiefe nicht verschieben.

+ *
+ * Nutzerauftrag vom 2026-08-29: "[?]help sollte eine Hilfeseite verlinken".
+ * Verlinken ist genau das, was hier nicht geht, und darum steht die Hilfe
+ * eingebaut da: die Oberflaeche ist per Vorgabe abgeschottet (PLAN Abschnitt 3),
+ * und ein Verweis ins Netz waere im Normalbetrieb ein Knopf, der nichts tut.
+ * Also ist die Seite Teil des Programms, offline vollstaendig, und die Verweise
+ * darin sind Pfade in diesem Repository.
+ *
+ * Vier Entscheidungen, und keine davon ist Geschmack:
+ *
+ * 1. **Overlay ueber der Editorflaeche, nach dem Muster des Flow-Erklaerers.**
+ *    Das Muster ist erprobt (W5c): eine eigene Ebene, nichts liegt davor, der
+ *    Kasten scrollt selbst. Ein Panel in der rechten Spalte waere ein langer
+ *    Text in einer 440 Pixel breiten Saeule, und ein Dialog mit Rand haette
+ *    dieselbe Hoehe mit weniger Platz darin.
+ * 2. **Die Grenzen stehen vor den Faehigkeiten.** Wer die Hilfe aufschlaegt,
+ *    liest im zweiten Abschnitt, was hier nicht geht, samt Grund. Erst danach
+ *    kommen die Panels. Ein Produkt, das seine Grenzen ans Ende stellt, laesst
+ *    den Leser sie selbst finden, und das ist die teuerste Art, sie zu erfahren.
+ * 3. **Die Tastentabelle wird abgelesen, nicht gepflegt.** Sie entsteht aus
+ *    ATLAS_SHORTCUTS (src/app/shortcuts.ts), also aus der Verdrahtung selbst.
+ *    Eine handgeschriebene Tabelle waere die naechste stille Luege: sie waere
+ *    beim ersten umbenannten Kuerzel falsch, und niemand haette es gemerkt.
+ * 4. **Der ganze Text steht im Katalog** (src/i18n/messages.ts), wie jeder
+ *    andere Satz des Rahmens. Hier steht nur, in welcher Reihenfolge er
+ *    dasteht.

+/**
+ * Der typisierte Katalog der sichtbaren Chrome-Strings.
+ *
+ * Die Mechanik ist die des PR-Frontends: EIN Objekt,
+ * `as const`, nach Bereichen geordnet, und alles, was eine Zahl oder einen Namen
+ * einsetzen muss, ist eine Funktion statt einer Zeichenkette mit Platzhaltern.
+ * Eine Funktion kann der Uebersetzer nicht falsch zusammensetzen, und der
+ * Aufrufer bekommt die Stelligkeit vom Typ gesagt.
+ *
+ * ## Was hier steht und was ausdruecklich nicht
+ *
+ * Hier stehen die Saetze des RAHMENS: Kopfzeile, Menue, Tabs, Statusleiste,
+ * Explorer, Kommandozeile, Reader-Notizen, Suchfenster, Why-Karten, Tour-Karte
+ * und die Rahmen von Einstiegsdialog, BUG-Assistent, Impact-Ansicht,
+ * Sidecar-Karte und Chat.
+ *
+ * Hier stehen NICHT die Fachtexte der portierten Module. `src/twin/strings.ts`,
+ * `src/pseudocode/pseudocode-strings.ts`, `src/impact/impact-strings.ts`,
+ * `src/traces/bug-wizard-strings.ts`, `src/chat/chat-strings.ts`,
+ * `src/llm/strings.ts`, `src/app/coverage-strings.ts` und `src/why/why-model.ts`
+ * bleiben die Quelle ihrer eigenen Saetze. Das ist kein Versaeumnis, sondern der
+ * Standard, aus dem dieses Muster kommt: ein Fachtext gehoert neben die Regel,
+ * die ihn begruendet, und ein zweiter Ort fuer denselben Satz waere ein zweiter
+ * Ort, an dem ihn jemand schaerft.
+ *
+ * ## Ein Baum, eine Sprache, und keine erfundene zweite
+ *
+ * Es gibt genau `en`. Ein `zh`-Baum mit maschinell erzeugten Saetzen waere eine
+ * unuebersetzte Luege in einer Struktur, die behauptet, uebersetzt zu sein. Die
+ * Struktur ist erweiterbar: ein zweiter Baum derselben Form neben `messages` und
+ * eine Wahl darueber, und keine Aufrufstelle aendert sich.
+ *
+ * ## Der eine Satz, der hier nicht englisch war
+ *
+ * `llm.readFrom` lautete "gelesen aus ...", als einziger Eintrag des Katalogs.
+ * W6a hat ihn hierher verschoben und ausdruecklich nicht umgeschrieben, weil
+ * jener Zyklus Saetze verschob; aufgefallen ist er, weil der Katalog ihn neben
+ * seine Nachbarn stellte, und genau dafuer ist ein Katalog da. Das unabhaengige
+ * Audit hat ihn als Befund 14 aufgeschrieben, und seit dem 2026-08-29 heisst er
+ * "read from ...". Der Katalog ist jetzt in einer Sprache, was die Voraussetzung
+ * dafuer ist, dass ein zweiter Baum daneben eine Uebersetzung waere und nicht
+ * eine zweite Mischung.

+/**
+ * What a change would reach, and the word that says how much of it matters.
+ *
+ * The body is the reference project's impact view in the order it draws it
+ * (CodeAtlasIDE, codeatlas-views/src/browser/impact-widget.tsx): a toolbar with
+ * the comparison point, then the tiles, then the badge and its reasoning, then
+ * the narrative with one evidence row per claim, then the four lists. What is
+ * not here is the review mode and the staleness banner, both of which need a
+ * reviewed baseline and a file watcher this surface does not have; a control
+ * that led to a sentence about why it cannot work would be worse than no
+ * control.
+ *
+ * Two decisions are this file's own.
+ *
+ * **A ref is refused here, before anything is asked.** The reference lets its
+ * backend refuse, because that backend has a repository in front of it. This one
+ * does not: `detect_changes` takes an unknown `since` without complaint and
+ * answers about the working tree, so a typo would come back as a plausible
+ * answer to a different question. So the format is checked in the browser
+ * (`refRejection`), the sentence names the rule that was broken and says that
+ * nothing was asked, and the request is simply not made. The proof run counts
+ * the requests on the wire and reads that count as the claim.
+ *
+ * **The badge lists the rules that fired.** A word with a paragraph beside it is
+ * still a word somebody has to take on trust. `badgeRules` turns the state that
+ * produced it back into sentences, one per rule, and they sit under the badge.
+ *
+ * Purely presentational: what to read is App.tsx's business, what it means is
+ * impact-model.ts's, and this file draws it.

+ *
+ * Aenderungen gegenueber dem Original, beide unten am Ort begruendet:
+ *
+ * - Die Importe zeigen auf die ebenfalls portierten Dateien dieses Projekts
+ *   (core/intelligence-provider.ts, core/semantic-ir.ts, impact-strings.ts).
+ *   PROGRAM_START_NAMES stand dort in map/map-model.ts; eine Karte gibt es hier
+ *   nicht, also steht die Liste hier, mit derselben Begruendung.
+ * - Dazu kommen zwei Bausteine, die es dort nicht gibt und hier geben muss:
+ *   {@link refRejection} prueft einen git-Ref im Browser, weil dieses Backend
+ *   keinen Ref ablehnt, sondern einen unbekannten kommentarlos annimmt und ueber
+ *   den Arbeitsbaum antwortet; und {@link badgeRules} zaehlt die erfuellten
+ *   Regeln als Saetze auf, weil das Wort neben der Erzaehlung sonst eine
+ *   Behauptung ohne Herleitung waere.

+/**
+ * Turning a change set into the page the impact view draws.
+ *
+ * Pure by rule, like the tour generator next door: a document in, a document
+ * out, no widget and no service. That matters more here than anywhere else in
+ * the product, because this is the file that decides to print the word HIGH, and
+ * a judgement that can only be checked by driving a browser is a judgement
+ * nobody checks.
+ *
+ * Four decisions shape everything below.
+ *
+ * **A file is not a symbol.** The analysis reports the changed file itself as
+ * an impacted symbol, labelled `Module` and named after its own path. Those
+ * rows are counted as changed files, never as changed symbols, and never given
+ * a risk level: "the risk of orderService.ts" is not a sentence with a meaning,
+ * and a page that printed one would be padding its own summary.
+ *
+ * **An endpoint is matched two ways and says which.** A route whose
+ * registration names a handler the change reaches is a strong claim. A route
+ * whose registration merely sits in a file the change reaches is a weaker one,
+ * and it is the only one available for TypeScript, where the routes are read
+ * off the source text and no handler is named. Both are shown; the second says
+ * that it is the file rather than the function.
+ *
+ * **Every sentence carries the reading it came from.** The narrative is a list
+ * of claims, each with an evidence row naming the source and the figures behind
+ * it. There is no sentence in the output that a reader cannot trace, which is
+ * what makes the risk word answerable rather than authoritative.
+ *
+ * **What was not looked at is stated.** Test callers are looked up for a capped
+ * number of symbols and complexity is unavailable for whole languages. Both
+ * produce a sentence rather than a silence, because a quiet page and a clean
+ * page look identical.

+ * that a page appeared, and only a unit test can prove that the page was built
+ * out of four readings and not out of three and a default.
+ *
+ *  1. **The change set.** `detect_changes` through the provider, which reads the
+ *     tool's answer in whichever of its two shapes arrived and recovers the
+ *     identities the answer leaves out.
+ *  2. **The summary**, for the entry points and the hotspot fan-in.
+ *  3. **The routes.** Not in the summary for TypeScript, so they are read off
+ *     the source text; see route-scan.ts for the whole of that gap.
+ *  4. **The per-symbol readings.** Complexity for the affected set in one batch,
+ *     and test callers one symbol at a time, capped.
+ *
+ * The cap on the test lookup is the one bound that changes what the page claims,
+ * so it is carried into the model rather than applied and forgotten: a symbol
+ * past it is unchecked, which is neither covered nor uncovered, and the
+ * narrative says how many.

+ * is shaped that way.
+ *
+ * **A risk level is a claim, so it has to be checkable.** CodeAtlas tells a
+ * reader that a change is high risk. The only defensible version of that
+ * sentence is one where the reader can ask "why" and get "because a route
+ * handler is in the change set", not "because it scored 7.4". Every branch
+ * below corresponds to a sentence somebody can disagree with.
+ *
+ * **A missing reading is not a zero.** The analysis records complexity for the
+ * languages it measures and nothing for the rest, and a symbol nobody measured
+ * is not a simple symbol. The rules treat an absent number as absent, which for
+ * the arithmetic means it cannot raise the level, and {@link completenessOf}
+ * counts how many symbols were in that position so the surface can say so out
+ * loud. Silently reading a missing cyclomatic complexity as 0 and then printing
+ * "low risk" would be the exact failure this product exists to avoid.
+ *
+ * **Pure, and no vocabulary.** No rendering library, no service, no sentence.

+/**
+ * The routes of a project, read off its source text because the index has none.
+ *
+ * The gap is the reference project's and it is unchanged here: the analysis
+ * writes route nodes for annotation-driven Java and reports them under the
+ * `routes` aspect, and writes none at all for TypeScript, JavaScript and Python.
+ * Measured against the built server of PR 1860 on fixtures/atlas-sample,
+ * `get_architecture` carries no `routes` key whatsoever. A change view that read
+ * only the index would therefore tell a Node reader that their application has
+ * no endpoints, which is the confident-empty-list failure this product exists to
+ * avoid.
+ *
+ * src/provider/route-reader.ts is the pure reader and it was ported unchanged;
+ * what it needs and does not have in a browser is somebody to hand it the text.
+ * That is this file. The provider's own `scanRoutes` cannot do it: it wants a
+ * synchronous file system, and here every file is a request.
+ *
+ * Three bounds, and all three are reported rather than applied quietly:
+ *
+ *  1. **A cap on files.** Every file is two requests (the module node, then the
+ *     snippet), so a repository of two thousand sources would be four thousand
+ *     round trips for one panel. {@link MAX_ROUTE_SCAN_FILES} is where the scan
+ *     stops, and {@link RouteScan.cappedAt} says so.
+ *  2. **Only the extensions the reader knows.** Anything else is skipped whole
+ *     and not counted as scanned, because "we looked and found nothing" and "we
+ *     did not look" are different claims.
+ *  3. **A file that arrived incomplete is named.** The reader gets whatever the
+ *     snippet route returned, and a registration past the cut is not on the
+ *     list. {@link RouteScan.truncatedFiles} is how a surface says so.
+ *
+ * Every route recovered this way is marked `source` all the way to the screen,
+ * exactly as in the reference.

+/**
+ * The review checklist: what a reader still owes before claiming they
+ * understand a symbol.
+ *
+ * Three properties are load-bearing.
+ *
+ * Identity is stable across rebuilds. An item's id is a hash of its category
+ * and of what it points at, never of its position in the list or of the index
+ * generation. That is what lets a reader tick "understand the call to
+ * validateUser", reindex the workspace, and still find the item ticked. Hashing
+ * the label instead would break the moment the wording is improved, so the
+ * qualified name of the target wins whenever there is one.
+ *
+ * Identity is also stable across a move. Every key below names something about
+ * the repository and nothing about the machine holding it: a qualified name
+ * where the graph resolved one, and a workspace-relative path where it did not.
+ * The tests category is the one that has to fall back to a path, because the
+ * 0.9.0 engine records a test caller as a file and a name rather than as a
+ * resolved symbol, and that path is made relative here. Keying it on the
+ * absolute URI, as this generator did until C19, meant that cloning a
+ * repository into another directory silently dropped exactly one category of
+ * the reader's record while keeping the rest. The direction was safe, since a
+ * lost mark understates what somebody has read, but it was arbitrary, and a
+ * product whose subject is honesty about what is known cannot have one category
+ * quietly forgetting itself.
+ *
+ * Marks recorded under the old absolute keys are not migrated. They stay in the
+ * workspace's `understanding.json` as entries nothing asks for any more, so
+ * nothing is destroyed; the tests rows come back unticked once, and from then
+ * on they survive a move like every other row.
+ *
+ * An empty category is omitted, never rendered empty. A checklist that shows
+ * "Error handling" with nothing under it reads as "this symbol raises nothing",
+ * which is a claim this generator is in no position to make: it sees the facts
+ * it was given and not the reason they are empty. The knowledge state that
+ * explains an absence lives on the `Fact`, and the panel renders it there.
+ *
+ * Items are derived, never invented. Every item points at something the graph
+ * returned, so every item can be opened.
+ *
+ * That last property is now carried by the item itself. An item's `target` is
+ * the place following it goes: the callee for a call, the caller for a caller,
+ * the raise site for an error, the focused symbol itself for the obligations
+ * that are about the symbol rather than about somewhere else. Before this, the
+ * target was recovered by each consumer from the facts beside the checklist,
+ * which meant two surfaces could disagree about where the same item led. A
+ * consumer with a fallback of its own may keep it for items whose target could
+ * not be resolved; it will simply stop being reached for the ones that can.

+/**
+ * Assembling one symbol's semantic IR out of the provider's fact families.
+ *
+ * Four rules shape everything below.
+ *
+ * Rule one: a build never fails. The IR is what a panel renders, and a panel
+ * that renders nothing because one of six queries timed out is worse than a
+ * panel that renders five families and says the sixth is unknown. Every fan-out
+ * leg is therefore wrapped, and a failed leg produces a `Fact` in state
+ * `unknown` with no evidence plus one warning naming the family.
+ *
+ * Rule two: the fan-out is parallel, because the families are independent and
+ * the twin is on the interaction path. The only families issued together are
+ * callers and tests, and only because the provider derives the tested-by
+ * inference from the caller rows: asking separately would run the same query
+ * twice and could return two answers that disagree.
+ *
+ * Rule three: nothing here invents a fact. The purpose sentence is a template
+ * over counts the provider actually returned, and it says so by being
+ * `inferred` with a named strategy rather than `known`. When the engine grows
+ * a docstring relation this is the one function that changes.
+ *
+ * Rule four: file references leave here as absolute URIs. The engine reports
+ * workspace-relative paths, the editor opens URIs, and doing the conversion in
+ * every consumer is how a UI ends up opening `src/util/validate.ts` relative to
+ * whatever the process happened to have as its working directory.

+/**
+ * Der Erklaeren-Bereich: EIN Platz unter dem Reader, in dem alles liegt, was den
+ * gelesenen Code erklaert, und immer genau eins davon zu sehen ist.
+ *
+ * ## Der Befund, gegen den dieser Bereich geschnitten ist
+ *
+ * Nutzerbefund vom 2026-08-29 mit Screenshot: Flow-Erklaerer, Antwort-Panel und
+ * Schrittkarte standen gleichzeitig offen, ueberlagerten sich, und alle drei
+ * waren angeschnitten. Der Massstab, den der Nutzer dazu genannt hat, ist der
+ * ganze Entwurf dieses Bereichs: "es soll intuitiv sein wie Apple und nicht
+ * verwirren; die Oberflaeche ist hauptsaechlich dafuer da, dass Devs Code besser
+ * verstehen".
+ *
+ * Daraus folgen drei Entscheidungen, und keine davon ist Geschmack:
+ *
+ * 1. **Was einander ersetzt, teilt sich einen Platz.** Flow, Walk, Chat und die
+ *    beiden Assistenten beantworten alle dieselbe Frage ("was tut der Code, den
+ *    ich lese") auf verschiedene Weise. Zwei Antworten auf dieselbe Frage
+ *    gleichzeitig sind keine zwei Antworten, sondern eine halbe: der Leser muss
+ *    erst entscheiden, welche der beiden er meint. Also gilt immer genau eine,
+ *    und der Wechsel ist ein Reiter.
+ * 2. **Der Wechsel kostet nichts.** Der Zustand jeder Flaeche liegt oben in
+ *    App.tsx und nicht in ihr. Ein Reiterwechsel haengt darum nur ihre
+ *    Darstellung aus und nicht ihren Verlauf: der Chat behaelt seine Fragen, der
+ *    Walk seinen Schritt, der Flow seine Stelle. Das ist der Grund, aus dem hier
+ *    NUR der aktive Reiter im DOM steht: haetten alle fuenf ihren eigenen
+ *    Zustand, muessten sie alle haengenbleiben, und dann waeren wieder fuenf
+ *    Flaechen an einem Platz.
+ * 3. **Ruhe ist der Normalfall.** Beim Oeffnen eines Projekts ist der Bereich
+ *    eingeklappt. Er ist dann ein Streifen mit seinen Reitern und einer Zeile,
+ *    die sagt, was drinliegt, und keine Leere: ein Bereich, der ganz
+ *    verschwaende, waere eine Funktion, die man erst wiederfinden muss.
+ *
+ * ## Warum der eingeklappte Streifen seine Reiter behaelt
+ *
+ * Weil er sonst ein Knopf waere, hinter dem etwas Unbekanntes liegt. Mit den
+ * Reitern ist er ein Inhaltsverzeichnis: der Leser sieht, dass es einen Chat
+ * gibt, dass eine Fuehrung laeuft, und ein Klick oeffnet genau das. Das ist auch
+ * die Antwort auf die Frage, die W7c fuer den Chat schon beantworten musste
+ * ("ist mein Verlauf noch da?"): die Zeile daneben sagt es.

+/**
+ * Ein Griff zwischen zwei Zonen. Vier davon gibt es, und sie sind dieselbe
+ * Datei, weil sie dasselbe tun.
+ *
+ * ## Was ein Griff koennen muss, damit er einer ist
+ *
+ * **Die Maus.** Druecken, ziehen, loslassen, und der Zeiger bleibt beim Griff,
+ * auch wenn er dabei ueber den Editor faehrt (`setPointerCapture`). Ohne das
+ * Einfangen reisst der Zug ab, sobald der Zeiger eine Flaeche erwischt, die
+ * selbst auf Zeiger hoert, und das ist bei einem 6 Pixel breiten Griff nach zwei
+ * Pixeln der Fall.
+ *
+ * **Die Tastatur.** Fokussierbar, Pfeiltasten, und Shift fuer den grossen
+ * Schritt. Ein Griff, den nur die Maus erreicht, ist ein halber Griff; das gilt
+ * hier doppelt, weil diese Oberflaeche ihr ganzes Vorbild aus der Tastatur zieht
+ * (PLAN Abschnitt 4).
+ *
+ * **Den Weg zurueck.** Doppelklick setzt genau diese eine Grenze auf ihre
+ * Vorgabe. Wer eine Zone zu weit gezogen hat, will nicht das ganze Layout
+ * zuruecksetzen, sondern die eine Grenze, an der er gerade steht.
+ *
+ * **Sagen, wo er steht.** `role="separator"` mit `aria-valuenow`, `aria-valuemin`
+ * und `aria-valuemax`, denn genau das ist er: eine verschiebbare Trennlinie mit
+ * einem Bereich. Die drei Zahlen sind ausserdem das, woran der Beweislauf ihn
+ * misst, statt aus Pixeln zu raten, was die Oberflaeche gerade meint.
+ *
+ * ## Was er NICHT mehr tut: sich erklaeren
+ *
+ * Bis W10b hing an jedem der vier Griffe ein vierzeiliger Kasten, der das Ziehen,
+ * die Pfeiltasten und den Doppelklick beschrieb. Nutzerauftrag vom 2026-08-29,
+ * 23:14, mit Screenshot: "diese Meldung nicht anzeigen, das wird klar durch alles
+ * andere. Bitte an allen Bordern die Meldung entfernen." Er hat recht, und der
+ * Grund liegt eine Zeile weiter oben in dieser Datei: seit W8b traegt jeder Griff
+ * eine sichtbare Marke und zehn Pixel Trefferflaeche. Der Kasten erklaerte damit
+ * etwas, das man sieht, und verdeckte dafuer Inhalt.
+ *
+ * Entfernt ist die BESCHREIBUNG, nicht die Faehigkeit: `aria-label` sagt weiter,
+ * welche Grenze das ist, `aria-valuetext` sagt, wo sie steht, und die Tastatur
+ * bedient sie unveraendert. Ein Vorleseprogramm erfaehrt also genau so viel wie
+ * vorher; nur das Fenster ueber dem Text ist weg.
+ *
+ * ## Warum der Zug nicht im Zustand liegt
+ *
+ * Zwischen zwei Bildern passieren zwanzig Zeigerereignisse. Jedes davon als
+ * Zustandsaenderung waere zwanzig Bilder, in denen nichts zu sehen ist ausser
+ * der Bewegung, die der Browser ohnehin schon kennt. Was gezeichnet wird, ist
+ * die Groesse, und die gehoert dem Aufrufer; der Zug selbst liegt in einem Ref.
+ * Dieselbe Entscheidung wie beim Griff des Antwort-Panels in W7c, und sie hat
+ * dort ebenso wenig etwas mit Geschwindigkeit zu tun wie hier: sie haelt den
+ * Unterschied zwischen "der Leser bewegt gerade etwas" und "die Oberflaeche hat
+ * eine neue Groesse" sichtbar.

+ * Welche Reiter der Erklaeren-Bereich hat, welcher davon gerade etwas zu zeigen
+ * hat, und was der eingeklappte Streifen ueber ihn sagt.
+ *
+ * ## Warum ein Reiter, der nichts hat, trotzdem dasteht
+ *
+ * Bis W8 verschwand jede dieser Flaechen, sobald sie nichts hatte: kein Zug, kein
+ * Chat-Panel; keine Fuehrung, keine Schrittkarte. Das ist die bequeme Loesung und
+ * die falsche. Ein Bedienelement, das mal da ist und mal nicht, zwingt den Leser
+ * bei jeder Frage zuerst zu der Frage, wo es hin ist, und die Antwort "es gibt
+ * hier gerade nichts" bekommt er nie: er sieht nur eine Leere und muss raten, ob
+ * das Produkt es nicht kann, es nicht hat oder er es falsch bedient.
+ *
+ * Also steht jeder Reiter immer da. Hat er nichts, ist er gedimmt UND er sagt
+ * seinen Grund, und zwar im Feld darunter und nicht in einem Tooltip: dieselbe
+ * Regel, mit der W7a die Attrappen aus der Menuezeile geworfen hat. Ein Grund,
+ * den man nur mit der Maus findet, ist fuer den, der ihn braucht, nicht da.
+ *
+ * ## Warum die Reiter aus Tatsachen entstehen und nicht aus Zustandsschaltern
+ *
+ * `explainTabs` bekommt, was WAHR ist (steht ein Symbol im Twin, laeuft eine
+ * Fuehrung, wie viele Fragen liegen im Chat), und nicht, was OFFEN ist. Damit
+ * kann kein Reiter behaupten, er habe etwas, weil ihn jemand aufgeschlagen hat.
+ * Die Umkehrung waere genau der Fehler, gegen den dieses Produkt gebaut ist:
+ * eine Flaeche, die dasteht, weil sie geoeffnet wurde, und nicht, weil sie etwas
+ * zu sagen hat.

+/**
+ * Die Befehle, die die Kommandozeile ausser Suchen und Fragen kennt.
+ *
+ * ## Warum es sie gibt
+ *
+ * AC3 des W8-Contracts verlangt einen Weg zurueck, der in EINEM Schritt geht:
+ * wer sich mit vier Griffen ein Layout gebaut hat, das er nicht mehr mag, soll
+ * nicht vier Doppelklicks suchen muessen. Seit W10 steht `settings` daneben, aus
+ * demselben Grund: das Einstellungen-Panel ist die Stelle, an der ein Leser mit
+ * einer schwachen Maschine die teuren Effekte abschaltet, und es ueber ein
+ * Menuekuerzel allein erreichbar zu machen hiesse, es hinter einer Taste zu
+ * verstecken, die man kennen muss. Seit W11a steht `live agents` daneben, und dort ist der Grund noch
+ * schaerfer: der Live-Modus ist per Vorgabe AUS, und ein Modus, den man nur
+ * ueber ein Menuekuerzel findet, ist fuer den, der das Kuerzel nicht kennt, gar
+ * nicht da. Alle drei gibt es darum zweimal, im Menue und in der Zeile, und
+ * beide Wege rufen dieselbe Funktion.
+ *
+ * ## Warum die Erkennung hier steht und nicht in commandIntent
+ *
+ * `src/chat/command-intent.ts` beantwortet eine andere Frage, naemlich ob eine
+ * Zeile eine Suche oder eine Frage an das Modell ist. Ein Befehl ist keins von
+ * beidem, und ihn dort einzubauen hiesse, die Prioritaetsregel jenes Moduls
+ * anzufassen ("die Suche behaelt den Vortritt"), die auf einem Nutzerbefund
+ * beruht. Er wird darum VOR jener Frage geprueft, an einer eigenen Stelle, die
+ * genau drei Zeilen kennt.
+ *
+ * Drei Befehle an einer Stelle und nicht an dreien: die Frage "ist diese Zeile
+ * ein Befehl" wird einmal beantwortet, mit einer Normalisierung und einem
+ * Vergleich. Drei Module mit je einer Zeile waeren drei Normalisierungen, die
+ * auseinanderlaufen koennen.
+ *
+ * ## Warum die Erkennung so eng ist
+ *
+ * Nur `reset layout`, `settings` und `live agents`, ohne Gross-/Kleinschreibung und ohne
+ * doppelte Leerzeichen. Kein Praefix, kein Teilwort, keine Abkuerzung. Der Grund
+ * ist derselbe wie beim Fragezeichen in command-intent.ts: diese Zeile sucht
+ * auch, und jede Unschaerfe hier ist eine Suche, die stattdessen das Layout
+ * umbaut oder ein Panel aufschlaegt. "reset" allein ist ein Wort, nach dem
+ * jemand suchen wird; "reset layout" ist keins.
+ *
+ * `settings` ist ein einzelnes Wort und damit der engere Fall von beiden. Es ist
+ * trotzdem vertretbar, und der Grund ist messbar: dieses Produkt sucht Symbole
+ * eines indizierten Repositories, und ein Symbol heisst `getSettings`,
+ * `SettingsPanel` oder `settingsStore`, aber nicht `settings` allein; die Suche
+ * greift ausserdem ab zwei Zeichen und zeigt ihre Treffer, waehrend getippt
+ * wird, also sieht ein Leser, der wirklich sucht, seine Treffer schon vor dem
+ * achten Buchstaben. Wer die Zeile trotzdem abschickt, bekommt das Panel und
+ * schliesst es mit Escape.

+/**
+ * Die vier Masse des Layouts: wie breit, wie hoch, wie weit darf das gehen, und
+ * was davon ueberlebt einen Reload.
+ *
+ * Der Befund vom 2026-08-29 (Screenshot mit drei gleichzeitig offenen Flaechen)
+ * hat zwei Haelften. Die eine ist, WO etwas liegt, und die beantwortet
+ * src/app/AtlasChrome.tsx mit festen Zonen statt gestapelter Fenster. Die andere
+ * ist, WIE GROSS es ist, und die beantwortet diese Datei: der Leser zieht die
+ * Grenzen selbst, und was er gezogen hat, steht beim naechsten Oeffnen noch da.
+ *
+ * ## Warum die Grenzen aus dem Fenster kommen und nicht aus einer Tabelle
+ *
+ * Eine feste Hoechsthoehe ("das Erklaeren-Feld darf 620 Pixel hoch sein") ist
+ * auf einem grossen Bildschirm eine willkuerliche Fessel und auf einem kleinen
+ * eine Zusage, die die Oberflaeche nicht halten kann: 620 Pixel Erklaeren in
+ * einem 600 Pixel hohen Fenster heisst kein Reader mehr. Die Hoechstmasse sind
+ * darum ANTEILE des Fensters mit einem Deckel darauf, und die Mindestmasse sind
+ * absolute Zahlen: eine Zone, die kleiner als ihr Mindestmass ist, zeigt nichts
+ * mehr, und das haengt an der Schriftgroesse und nicht an der Fenstergroesse.
+ *
+ * Damit gilt die Zusage aus AC2 ("keine Zone darf wegziehbar sein") an jeder
+ * Fenstergroesse, und sie gilt zweifach: hier als Zahl, damit der Griff seine
+ * `aria-valuemin`/`aria-valuemax` ehrlich melden kann, und in terminal.css als
+ * `min-height`/`max-height`, damit auch ein Fenster, das zwischen zwei Bildern
+ * kleiner wird, keine Zone verschluckt. Zwei Stellen fuer dieselbe Grenze sind
+ * hier kein Widerspruch, sondern Guertel und Hosentraeger: die eine spricht,
+ * die andere zeichnet.
+ *
+ * ## Was hier von src/chat/chat-height.ts uebernommen wurde
+ *
+ * W7c hatte dem Antwort-Panel eine eigene ziehbare Hoehe gegeben, mit Grenzen,
+ * einer Schrittweite und einem Gedaechtnis in localStorage. Seit W8 ist der Chat
+ * ein Reiter und erbt die Hoehe seiner Zone; die drei Zusagen gelten unveraendert
+ * weiter, sie stehen nur nicht mehr neben dem Chat, sondern hier, wo sie fuer
+ * alle vier Grenzen gelten. Eine zweite Hoehe neben der der Zone waere genau der
+ * Stapel, den dieser Zyklus abschafft.

+ * Die committete Projekt-Policy und ihr Vorrang vor jeder Nutzerpraeferenz.
+ *
+ * Das Referenzprojekt kennt eine `.codeatlas/policy.json` im Zielrepository, mit
+ * der ein Team Faehigkeiten der IDE fuer dieses Repository abschaltet. Die
+ * Mechanik gilt hier sinngemaess und mit einer scharfen Grenze: die Datei gehoert
+ * dem INDEXIERTEN Projekt, nicht diesem Frontend. Sie wird also nicht vom
+ * Dateisystem gelesen, sondern ueber denselben Weg, ueber den auch der Reader an
+ * Quelltext kommt.
+ *
+ * ## Der Lese-Weg, gemessen und nicht vermutet
+ *
+ * `get_code_snippet` auf dem Modul-Knoten der Datei. Der Indexer legt fuer
+ * `.codeatlas/policy.json` einen Modul-Knoten `<projekt>.codeatlas.policy` mit
+ * Zeilenspanne an (gemessen am laufenden Server, verification/w5/sidecar.json,
+ * Feld `policyReadPath`), und das Snippet liefert die ganze Datei. Genau das tut
+ * `loadFileDocument` aus src/reader/file-source.ts, also wird es benutzt und
+ * nicht nachgebaut: ein zweiter Weg zu einer Datei waere eine zweite Stelle, an
+ * der eine Kappung gedeutet wird.
+ *
+ * `search_code` waere der andere gangbare Weg (er findet die Zeile `"llm":
+ * "deny"` als Variablen-Knoten mit 60-Zeilen-Fenster). Er ist NICHT genommen
+ * worden, weil er eine Zeile liefert statt einer Datei: eine Policy, von der man
+ * nur die Trefferzeile kennt, laesst sich nicht als JSON pruefen, und ein
+ * Regulaerausdruck auf `deny` wuerde auch in einem Kommentar anschlagen.
+ *
+ * ## Die Vorrangregel
+ *
+ * Die Policy schlaegt die Praeferenz, nie umgekehrt. Eine Praeferenz kann ein
+ * `deny` nicht aufheben, und der Schalter bleibt sichtbar, wird aber
+ * wirkungslos: ein verschwundener Schalter waere die Behauptung, es gaebe die
+ * Einstellung nicht.
+ *
+ * Eine vorhandene, aber unlesbare Policy sperrt ebenfalls. Das ist die einzige
+ * Stelle, an der diese Datei streng ist, und sie ist es mit Absicht: eine
+ * Steuerungsdatei, die man nicht lesen kann, ist keine Erlaubnis. Der Satz auf
+ * dem Bildschirm nennt dann die Datei und den Grund, damit die Sperre nicht
+ * raetselhaft ist. Eine FEHLENDE Datei sperrt nicht: dort hat niemand etwas
+ * gesagt, und dann gilt die Praeferenz.

+/**
+ * Der Zustand des lokalen Modell-Sidecars, und was die Oberflaeche darueber
+ * sagen darf.
+ *
+ * Der Sidecar ist ein eigener Prozess: llama-server aus vendor/llama, gestartet
+ * ueber llm/start.sh, gebunden an 127.0.0.1:4141. Diese Datei startet nichts und
+ * kann nichts starten. Sie fragt und sie deutet, und das ist die ganze
+ * Architektur-Grenze aus ADR 0001: eine SPA ohne eigenes Backend darf keinen
+ * Prozess versprechen, den sie nicht anfassen kann.
+ *
+ * Drei Entscheidungen, die man sonst raten muesste:
+ *
+ * 1. **Aus heisst aus, nicht "leise".** Solange die Praeferenz aus ist oder eine
+ *    Policy das LLM verbietet, faellt kein einziger fetch Richtung 4141. Kein
+ *    Aufwaerm-Ping, keine "gibt es dich"-Probe beim Laden. Der Beweislauf misst
+ *    genau diese Null am Netz-Mitschnitt, und ein einzelner Ping waere der
+ *    Unterschied zwischen einem Opt-out und einem Schalter, der nur die Anzeige
+ *    umfaerbt.
+ * 2. **Kein Prozess ist kein Fehler.** `not-running` ist der Normalfall nach dem
+ *    Einschalten, nicht ein Ausfall: der Leser hat das Skript noch nicht
+ *    gefahren. Die Oberflaeche nennt deshalb den konkreten Aufruf, statt eine
+ *    rote Meldung zu zeigen, die nach einem Defekt aussieht.
+ * 3. **Die Zahlen kommen aus dem laufenden Prozess, nicht aus einer Tabelle.**
+ *    Modell, Quantisierung, Kontext und Slots stehen in `/props`; die Groesse
+ *    der geladenen Gewichte steht dort NICHT und wird darum aus `/v1/models`
+ *    (`meta.size`) geholt und als "weights" benannt, nicht als
+ *    Prozessspeicher. Eine im Code gepflegte Modellgroessen-Tabelle waere eine
+ *    zweite Wahrheit neben dem Prozess, der die Datei wirklich geladen hat.
+ *
+ * ## Zwei Betriebsarten, und woran man sie unterscheidet (W10)
+ *
+ * llama-server kann als ROUTER ueber ein Cache-Verzeichnis laufen
+ * (`--models-dir`) statt mit einer festen Datei (`-m`). Nur im Router-Modus
+ * waehlt das Feld `model` einer Chat-Anfrage wirklich aus; ein Einzel-Server
+ * ignoriert ein fremdes `model` STILLSCHWEIGEND und antwortet mit dem Modell,
+ * das er ohnehin geladen hat (gemessen am 2026-08-29 an vendor/llama, Version
+ * 0.3.0-dev, build b1-90c26fc: die Anfrage mit `"model":"SomeOtherModel"` kam
+ * mit `"model":"models/MiniCPM5-1B-Q4_K_M.gguf"` und einem normalen Text
+ * zurueck, ohne Fehler und ohne Warnung).
+ *
+ * Genau darum wird die Betriebsart gelesen und nicht angenommen: eine Auswahl
+ * anzubieten, die stillschweigend nichts tut, waere die teuerste Sorte von
+ * Bedienelement. Das Merkmal ist `props.role === 'router'`; im Einzel-Modus
+ * fehlt das Feld ganz.
+ *
+ * Im Router-Modus sind die Zahlen in `/props` NICHT die des Modells: dort steht
+ * `model_path: "none"` und `n_ctx: 0`, weil der Router selbst keins geladen hat.
+ * Die Zahlen einer Instanz stehen in `/props?model=<id>`, und genau die werden
+ * dann geholt. Ohne diesen zweiten Weg wuerde die Statusleiste "ready: none"
+ * behaupten, waehrend ein Modell antwortet.

+/**
+ * The projects panel: what this server has indexed, how to give it more, and
+ * what the server is doing.
+ *
+ * It is the one surface of this frontend that asks the server to write, and
+ * it says so in every place where it does: index a repository (POST
+ * /api/index), remove an index (DELETE /api/project), store a decision record
+ * (POST /api/adr). The server does the work in its own process; this window
+ * only asks, then reads the answer back through the same routes it would read
+ * anyway.
+ *
+ * Three rules shape it, and they are the rules of the rest of this surface:
+ *
+ *  1. **Every block names its source.** The list says it comes from
+ *     list_projects, the jobs say they come from /api/index-status, the
+ *     frontend log names the file it is read from (GET /api/ui-log), and a
+ *     number the server did not send is shown as not sent, never as zero.
+ *  2. **A control that cannot act is not on the screen.** The index button
+ *     appears once a path and a name are there; a project whose root the
+ *     server did not report has no reindex button and a sentence instead.
+ *  3. **Deleting takes two steps, in place.** No browser dialog: the row turns
+ *     into the question, with the answer and the way back next to it.
+ *
+ * Why this panel exists at all, given that the help page describes a
+ * read-only product: the previous frontend of this repository let a reader
+ * index a project from the browser, and the first thing a new install shows is
+ * a server with nothing indexed. Sending that reader to the command line would
+ * be a capability the replacement took away. The panel keeps it, and keeps the
+ * writing confined to these three requests.

+ *
+ *   GET    /api/index-status         [{slot, status, path, error}]
+ *   POST   /api/index                {status: 'indexing', slot, path}   (202)

+ * The first `IntelligenceProvider` implementation.

+ * Its whole job is translation: product questions in, engine queries out,
+ * evidence-carrying facts back. Two rules make the translation honest.
+ *
+ * Rule one: an empty answer is not a fact until we know why it is empty. Every
+ * fact family therefore carries the state that explains its emptiness, and the
+ * decision is made by one pure function (`knowledgeStateFor`) so it can be
+ * tested as a table rather than as a pile of branches.
+ *
+ * Rule two: never dress a heuristic as a reading. The 0.9.0 engine records no
+ * test relation for TypeScript, so `testedBy` is derived from callers that the
+ * engine flagged as test code. That derivation is real and useful, and it is
+ * reported as `inferred` with the strategy named in the evidence, forever.
+ * An empty `testedBy` never becomes `known`, because "no test caller found"
+ * and "not tested" are different claims.

+     *    nothing, so the "downstream" half of the question is not answered at
+     *    all. That walk is done here, one query per step, against the same
+     *    invocation relation the twin and the navigator read.
+     *  - It names those symbols by display name and file only: no qualified
+     *    name, no line. So they cannot be opened, cannot be asked a follow-up
+     *    question about, and cannot be told apart from a same-named symbol in
+     *    another file. The identities are recovered from the index.
+     *  - It repeats both lists once per repeated changed file.
+     *
+     * The server of PR 1860 answers the other way round, and the difference is
+     * decided per row by the `hop` column: `impacted` holds the transitive
+     * CALLERS of the changed declarations, each with its distance, and the
+     * changed declarations themselves are reported only as a number
+     * (`seed_symbols`), scoped to the changed hunks. So a row with a step is
+     * read as a caller at that step and the walk below is left to the server,
+     * and the changed symbols are recovered from the index. Which of the two
+     * answers arrived is never assumed; it is read off the row.
+     *
+     * That recovery is the one thing the 0.9.0 reading deliberately refused,
+     * and it is refused here too wherever the tool did name declarations: an
+     * empty symbol list from a non-empty file list is a finding, and it means

+     * a *count* and no names, because then the index is the only place those
+     * names exist and answering "no changed symbol" would report a gap in the
+     * answer as a fact about the change. What comes back is then exactly "every

+/**
+ * The connected part of the graph around one symbol: what it reaches, bounded
+ * twice and honest about both bounds.
+ *
+ * Written to the specification of `getClosure` in CodeAtlasIDE
+ * (theia-extensions/codeatlas-intelligence/src/node/intelligence-server-impl.ts,
+ * `getClosure`/`walkClosure`/`resolveCallee`, plus the DTO and the four bounds
+ * in codeatlas-core/src/common/intelligence-rpc.ts). It is a reimplementation
+ * rather than a port: there the walk sits in a Theia backend behind an RPC
+ * facade with a cache keyed on the index generation, and here it is a function
+ * the browser calls straight against the provider. Every rule below is that
+ * specification's rule; what is not carried over is the RPC shell, the cache and
+ * the `symbols`/`edges` split of the DTO (see {@link ClosureResult}).
+ *
+ * ## Five properties are load-bearing
+ *
+ * **The walk is breadth first and alphabetical within a layer.** Two calls
+ * against one index therefore produce the same document, which is what lets a
+ * forward walk be compared with the one a colleague sees and keeps a tour from
+ * reshuffling between two readings of the same code. The engine's own row order
+ * is not stable enough to rely on. The comparison is ordinal, never
+ * `localeCompare`: that is the same determinism rule the tour generator states,
+ * and it is the one place this implementation is deliberately stricter than the
+ * reference, which sorts one intermediate list by collation before re-sorting it
+ * ordinally. Two machines with different collations would otherwise emit the
+ * edges of one layer in two orders.
+ *
+ * **A symbol is visited once.** A qualified name already reached is not expanded
+ * again, so a recursive chain terminates; the edge back into it is still
+ * recorded, because a cycle is a fact about the code and a walk that dropped the
+ * closing edge would draw a chain that stops for no reason.
+ *
+ * **Every symbol is resolved before it is published.** A call site names a file
+ * and a line; that is a place, not a symbol, and publishing it as one would hand
+ * a reference with no `nodeId` to the rest of the product, which reads that as
+ * "not indexed". So each newly reached callee is resolved back into the symbol
+ * the index knows, at the declaration line rather than at the call line. A
+ * callee the index will not resolve is kept, without a `nodeId`, because leaving
+ * it out would silently shorten the answer and inventing one would be a lie
+ * about the index.
+ *
+ * **Both bounds are visible.** A layer past `depth` and a symbol past `cap` both
+ * set `truncated`, and `visited` counts what the walk saw including what it
+ * refused, so a surface can say how much is missing rather than drawing a floor
+ * as a total.
+ *
+ * **Edges only ever join two returned symbols.** A call whose target the cap
+ * refused is not an edge with a dangling end; it is counted as truncation.

+ *  - A pattern carries at most one label, so a query that needs several labels
+ *    runs several times. That is why resolution issues one query per label.
+ *  - An unknown property returns the empty string rather than failing, so a
+ *    typo in a property name reads as "no data" instead of as an error. The

+/**
+ * Recovering HTTP routes from source text, for the languages the index does not.
+ *
+ * This file exists because of a gap, and the gap is worth stating plainly. The
+ * 0.9.0 analysis writes route nodes for annotation-driven Java and reports them
+ * under the `routes` aspect. For TypeScript, JavaScript and Python it writes
+ * none at all: a file that registers three routes produces three call edges and
+ * nothing that names a method or a path. A workspace map that showed only what
+ * the index reports would therefore tell a Node or a Flask reader that their
+ * application has no entry points, which is the confident-empty-list failure
+ * this product exists to avoid.
+ *
+ * So the routes are read off the text instead, and every route recovered this
+ * way is marked `source` rather than `index` all the way to the screen. Three
+ * rules keep that reading honest rather than clever:
+ *
+ *  1. **A literal or nothing.** Only a registration whose path is a string
+ *     literal is reported. `router.get(basePath + '/users', ...)` is invisible
+ *     here, and inventing `basePath` would be a guess about a value.
+ *  2. **A path, not a key.** A candidate is only a route when the literal
+ *     starts with `/`. Without that rule `cache.get('user')` and
+ *     `map.delete(id)` become routes, and a map full of imaginary endpoints is
+ *     worse than a map with none.
+ *  3. **No handler is named here.** The registration's line is reported and
+ *     nothing else. Which symbol encloses that line is a question for the
+ *     index, asked when a reader clicks the row, because that answer is a
+ *     reading and this file only has text.
+ *
+ * Everything below is pure: text in, findings out. No file system, no engine.

+/**
+ * Eine getypte Methode je Engine-Werkzeug, gesprochen ueber POST /rpc.
+ *
+ * Diese Schicht hat drei Aufgaben und keine vierte: das Werkzeug benennen, die
+ * Antwort auspacken und ihre Form pruefen. Sie kennt kein Produktvokabular und
+ * faellt kein Urteil darueber, was ein Ergebnis bedeutet; das ist Sache des
+ * Providers. Vorbild ist IntelligenceClient aus CodeAtlasIDE
+ * (theia-extensions/codeatlas-intelligence/src/node/client/intelligence-client.ts),
+ * die Methodenliste ist dieselbe. Der Transport ist ein anderer, und die
+ * Unterschiede sind der Inhalt dieser Datei.
+ *
+ * **Kein Kindprozess.** Das Original startete je Aufruf die CLI. Hier laeuft
+ * alles im Browser gegen den Server aus PR 1860, also ueber fetch. Nichts
+ * unter src/** darf einen Prozess starten, und nichts hier tut es.
+ *
+ * **Zwei Drahtformen statt einer.** Die 0.9.0-CLI antwortete auf alles mit
+ * JSON. Der Server antwortet je Werkzeug verschieden, und das ist gegen den
+ * gebauten Server geprueft, nicht angenommen:
+ *
+ * - `query_graph` liefert die kompakte Zeilenform. Sie geht durch
+ *   parseCompactRows und wird zu `{columns, rows}`, also genau die Form, die
+ *   der portierte Provider vorher von der CLI bekam.
+ * - `search_graph` liefert bei einer BM25-Anfrage die flache Suchform, die
+ *   parseSearchResults liest.
+ * - `list_projects`, `index_status` und `get_code_snippet` liefern JSON von
+ *   sich aus.
+ * - `detect_changes`, `get_architecture` und `trace_path` liefern eine
+ *   Textform fuer Menschen, es sei denn, man bittet mit `format: "json"` um
+ *   Daten. Genau das tun die Methoden unten. Ein Parser fuer die Textform
+ *   waere ein zweiter, stiller Vertrag ueber eine Anzeige gewesen.
+ *
+ * **Drei Werkzeuge gibt es hier nicht.** `index_repository`, `delete_project`
+ * und `ingest_traces` beantwortet die Read-only-Allowlist des Servers mit 403
+ * und -32601. Die Methoden sind trotzdem da und werfen sofort, statt zu
+ * fehlen: eine fehlende Methode waere ein Uebersetzungsfehler beim Aufrufer,
+ * ein klarer Fehler ist eine Aussage ueber diese Oberflaeche. Indiziert wird
+ * ueber die CLI, nicht von hier.

+ *    handgeschriebene Leser. Nicht aus Sparsamkeit: dieser Code laeuft im
+ *    Browser und das Projekt zieht in diesem Zyklus keine neue Abhaengigkeit.
+ *    Die Leser sind dieselbe Art Vertrag wie die Schemas, nur ohne Bibliothek:
+ *    ein fehlender Schluessel wird zum dokumentierten Default, ein unbekannter
+ *    faellt weg statt den Aufruf zu versenken.
+ * 2. **Zwei Drahtformen statt einer.** Die 0.9.0-CLI lieferte Tabellen als
+ *    Liste von Objekten. Der Server aus PR 1860 liefert dieselbe Tabelle als
+ *    `{cols, rows}` und gruppierte Listen als `{cols, groups}` mit einem
+ *    `qn_prefix` je Gruppe. Beide werden hier auf die Objektform gebracht, die

+/**
+ * Der Flow-Erklaerer als Overlay ueber der Editorflaeche: links das
+ * Sequenzdiagramm, rechts die nach Symbolen gruppierte Schrittliste, darunter
+ * der Stepper und die zwei Ehrlichkeits-Absaetze.
+ *
+ * Vorbild ist der Explainer des Referenzprojekts (CodeAtlasIDE,
+ * theia-extensions/codeatlas-views/src/browser/pseudocode/flow-explainer.tsx):
+ * derselbe Aufbau, derselbe Wortlaut, dieselbe Stepper-Mechanik. Fuenf
+ * Entscheidungen, und jede ist eine Antwort auf einen Befund aus dem
+ * Nutzerfeedback vom 2026-08-29:
+ *
+ * 1. **Ein eigener Platz und kein eingequetschter Kasten.** Der Kasten sass in
+ *    der rechten Spalte zwischen Kopfzeile und Detailstufen-Regler und
+ *    verschwand hinter ihnen, sobald er breiter wurde als die Spalte. Ein Bild,
+ *    das man scrollen muss, um es zu sehen, beantwortet die Frage nicht, fuer
+ *    die es da ist. W5c hat es darum ueber den Editor gelegt; seit W8 ist es
+ *    der Reiter `flow` des Erklaeren-Bereichs unter dem Reader. Beide Male
+ *    dieselbe Antwort auf denselben Befund, und die zweite ist die bessere: es
+ *    liegt nicht mehr VOR dem Code, den es erklaert, sondern daneben, und es
+ *    streitet sich mit keiner anderen Flaeche mehr um seinen Platz. Der Rahmen
+ *    (Zumachen, Escape, Hoehe) gehoert seitdem der Zone; hier steht nur noch
+ *    das Bild und was dazugehoert.
+ * 2. **Der Erklaerer haengt nicht an der Detailstufe.** Der flow()-Knopf steht
+ *    auf allen vier Stufen im Twin-Kopf, und was das Overlay zeigt, ist auf
+ *    allen vier dasselbe: der Walk ist eine Antwort ueber den Code und keine
+ *    ueber die Lesetiefe des Panels.
+ * 3. **Ein echtes Diagramm, aus eigenem SVG.** Keine Bibliothek: diese
+ *    Oberflaeche ist air-gapped und liefert keine aus. Die Geometrie rechnet
+ *    `flow-diagram.ts`, damit jede Zahl dieses Bildes ohne Browser pruefbar
+ *    ist; hier steht nur, wie sie aussieht. Alle Farben kommen aus tokens.css,
+ *    der helle Stil der Vorlage kommt ausdruecklich nicht mit.
+ * 4. **Die Liste ist nach Symbolen gruppiert und sagt, wo nichts steht.** Ein
+ *    Symbol des Walks, fuer das der Index nichts aufgezeichnet hat, traegt
+ *    seinen ehrlichen Satz statt einer leeren Zeile. Eine Gruppe ohne alles
+ *    liest sich wie ein Symbol, das nichts tut, und das ist eine andere
+ *    Behauptung als "der Index hat nichts aufgezeichnet".
+ * 5. **Der Stepper bewegt drei Dinge oder keins.** Diagramm, Liste und Editor
+ *    folgen demselben Index. Ein Schritt, der im Bild nichts anleuchtet (ein
+ *    Fehlerpfad ohne Lebenslinie im Bild, eine Umgebungslesung), sagt das,
+ *    statt irgendeinen Pfeil zu faerben.

+# Closure fixture provenance
+
+`closure-userService-create.json` was copied byte-for-byte on 2026-08-29 from
+Bernhard Jackiewicz's CodeAtlasIDE project, at
+`theia-extensions/codeatlas-views/test/fixtures/closure-userService-create.json`.
+It is an original contribution from the same author.
+
+The walk was assembled by hand from the IR recordings retained in
+`src/twin/__fixtures__/`; it is not a recorded backend closure response. Symbols,
+edges and line numbers come from those IRs. `depth: 3`, `cap: 8` and `truncated`
+exercise clipping, traversal order, cycle handling and flow folding.
+
+The source format uses `ClosureDto` fields `root`, `symbols`, `edges`, `truncated`,
+`visited`, `depth` and `cap`. The provider uses `nodes` instead of `symbols`;
+`closureDocumentOf` adapts that difference. Tests read the original fixture format.
+The IR files are shared with the twin tests instead of duplicated here.

+/**
+ * The one sentence over the block: what the finding is, in this block, today.
+ *
+ * No React, no DOM, no fetching. Two things in (what the file pulls in, and the
+ * block itself), one sentence out, so the surface renders a decision instead of
+ * making one.
+ *
+ * ## Why the block leads with this at all
+ *
+ * The block used to open with its heading and then its steps. Beside an
+ * eighteen line function that read "1. call validateId, 2. call query", and the
+ * code next to it showed a try, a catch, an early return and an object being
+ * built: a summary shorter than the thing it summarised and no faster to read.
+ * Meanwhile the one thing on the screen a reader could not have worked out for
+ * themselves, an import this symbol never reaches, sat below a heading that
+ * sounded like a footnote.
+ *
+ * So the order is by contribution: what the code does not show first, the steps
+ * after. This sentence is the top of that order.
+ *
+ * ## Two rules
+ *
+ * **There is no length threshold anywhere in this decision.** Nothing here asks
+ * how long the function is, how many steps it has or whether the block is
+ * "worth it". A number that decided when a function is short enough would be
+ * guessed, and a guessed number that removes content is the worst kind: it is
+ * invisible in the result. Every case below produces a lead, and the steps are
+ * drawn in every one of them.
+ *
+ * **The sentence always stands, including when there is nothing to report.** A
+ * head that only appeared when something was found would make its absence a
+ * claim, and an absence is exactly what this product refuses to sell as
+ * knowledge. When the imports check out and nothing is recorded behind the
+ * steps, the lead says so in those words.

+/**
+ * Das Sequenzdiagramm als Geometrie: wo jede Lebenslinie steht, wo jeder Pfeil
+ * ansetzt, und wo die Selbstschleife eines Fehlerpfades sitzt.
+ *
+ * Kein React, kein DOM, keine Diagramm-Bibliothek. Diese Datei rechnet aus der
+ * {@link FlowView} ein Koordinatenmodell, das ein Renderer eins zu eins in SVG
+ * ausgibt. Vier Entscheidungen, und keine davon ist Geschmack:
+ *
+ * **Die Rechnung steht hier, nicht im Renderer.** Ein Renderer, der selbst
+ * ausrechnet, wo ein Pfeil hingehoert, ist nicht pruefbar, ohne einen Browser zu
+ * starten. So ist jede Zahl dieses Bildes ein Unit-Test entfernt, und der
+ * Beweislauf im Browser prueft danach das, was ein Test nicht kann: dass man es
+ * sieht.
+ *
+ * **Ein Aufruf innerhalb einer Datei ist eine Selbstschleife.** Die
+ * Lebenslinien sind Dateien (so baut `flowSequence` sie), und `createUser` ruft
+ * `listUsers` in derselben Datei. Einen solchen Pfeil quer ueber das Bild zu
+ * zeichnen waere eine Linie von einer Spalte zu sich selbst, also gar keine
+ * Linie. Er wird als Schleife an seiner Spalte gezeichnet und traegt denselben
+ * Namen wie jeder andere Pfeil.
+ *
+ * **Ein erhobener Fehlertyp bekommt eine eigene Schleife, kein Pfeil.** Ein
+ * `may raise` ist keine Aufrufkante: der Index kennt die Stelle, an der der Typ
+ * herkommt, und nicht einen Aufruf, der ihn erzeugt. Die Schleife sitzt an der
+ * Datei, in der der Fehlertyp deklariert ist, weil das die einzige Datei ist,
+ * die der Fakt nennt. Kommt sie im Bild nicht vor, sitzt die Schleife an der
+ * Wurzel und die Beschriftung nennt trotzdem den Typ.
+ *
+ * **Zwei gleiche Schleifen sind eine.** Zwei Symbole des Walks koennen denselben
+ * Fehlertyp erheben. Zwei identisch beschriftete Schleifen uebereinander waeren
+ * dieselbe Aussage zweimal; die Liste rechts sagt weiterhin, welcher Schritt
+ * welcher war, und beide Schritte leuchten dieselbe Schleife an.

+/**
+ * What the imports group is allowed to say about an import and its full file.
+ *
+ * The suite is organised around the one mistake this feature can make that
+ * nobody would catch by looking at the screen. "unused import" is a sentence a
+ * reader will believe, it is what every linter they have ever used says, and
+ * CodeAtlas is in no position to say it from one focused symbol: it needs a
+ * complete callable reading of the file. So the tests are mostly about when the
+ * product must decline to answer.
+ *
+ * Three kinds of assertion:
+ *
+ *  1. A positive match is found, and it is found in the right family with the
+ *     right citation behind it. A `used` marker with no evidence is decoration.
+ *  2. A negative answer is `unused` only when every family the check would have
+ *     run against was actually answered, and `unknown` the moment one was not.
+ *     This is the difference between a finding and a gap, and it is asserted
+ *     from both directions.
+ *  3. The shapes that name nothing (a namespace binding, a side-effect import,
+ *     an entry recovered from an edge alone) are never called unused, because
+ *     there was never a name to look for.
+ *
+ * The IR is the committed recording of what the 0.9.0 provider actually returns
+ * for `createUser` in the frozen sample workspace, which is what makes the
+ * central case real rather than arranged: `insert` is imported and called,
+ * `query` is imported on the very same line and belongs to `listUsers` four
+ * lines up.

+/**
+ * What a file pulls in, and which names the complete file reading reaches.
+ *
+ * No React, no DOM, no services, no fetching. Two things in, one group out: the
+ * import list the backend read for a file, and the semantic IR of every callable
+ * declaration in that file. Both surfaces that draw this (the pseudocode block
+ * and the twin's data chips) call this one function, so the block and the panel
+ * can never disagree about whether the file reaches `query`.
+ *
+ * The feature exists because of one sentence of user feedback: the imports are
+ * not explained. They are the first thing anybody reads in an unfamiliar file
+ * and the last thing this product had anything to say about.
+ *
+ * Four rules make that safe to put on screen.
+ *
+ * **Three answers, not two.** The tempting design has a boolean, and the boolean
+ * is a lie in one direction. A linter says "unused import" after parsing the
+ * file; CodeAtlas has a list of names and recorded facts for every callable in
+ * the file. The absence of a match means one of two very different things
+ * depending on whether the family that would have carried the match was
+ * answered at all. So a name a fact mentions is `used`, a name no fact mentions
+ * *in families the index answered* is `unused`, and a name whose file-wide
+ * check could not be run is `unknown`.
+ * The third one is the whole point: claiming `unused` when `typeRefs` came back
+ * `notIndexed` would be inventing a finding out of a gap.
+ *
+ * **`unused` is about the complete file, never the focused symbol.** `query`
+ * is imported at the top of `userService.ts` and `createUser` never touches it;
+ * `listUsers`, four lines up, does. A focused symbol alone therefore cannot
+ * establish a negative file claim. If the complete callable reading is absent
+ * or partial, every named import remains `unknown`.
+ *
+ * **A positive match wins outright.** If any family names the import, the entry
+ * is `used`, whatever state the other families are in. A missing family can only
+ * ever weaken a negative answer; it cannot weaken a match that was found.
+ *
+ * **The two readings stay apart.** The dependency between two files is the
+ * analysis speaking. The statement, its line and the name it binds are CodeAtlas
+ * reading the file. Every entry carries a citation for each of the two it has,
+ * so a reader who opens the evidence on a chip sees exactly which half of the
+ * claim came from where; an entry whose only citation is the import is an entry
+ * that proves the import and nothing about its use, and it says so.

+ * Woher die Imports-Gruppe ihre Daten bekommt.

+ * Im Referenzprojekt (CodeAtlasIDE) ist das eine Zeile: der Twin ruft
+ * `pseudocode-service.importsFor(symbol, [ir])`, der Dienst ruft
+ * `provider.fileImports(root, relativePath)`, und ein Theia-Backend setzt die
+ * Antwort aus zwei Lesungen zusammen. Dieses Projekt hat kein solches Backend.
+ * Der C-Server bietet auf /rpc kein Werkzeug an, das die Importe einer Datei mit
+ * Namen und Zeilen gemeinsam zurueckgibt. Derselbe DTO wird aus zwei Lesungen gebaut,
+ * die es schon gibt, und diese Datei ist genau diese duenne Beschaffung.
+ *
+ * **Die beiden Lesungen, und warum es zwei sein muessen.**
+ *
+ * Die erste ist die Analyse: `moduleDependencies` liefert Datei-zu-Datei-Kanten.
+ * Das ist ein Befund des Index, und mehr als zwei Pfade steht nicht drin: kein
+ * importierter Name, keine Zeile, und gar keine Kante fuer ein Modul, das
+ * ausserhalb des Arbeitsbereichs aufloest.
+ *
+ * Die zweite ist der Text der Datei selbst, den der Reader ohnehin schon
+ * geladen hat. Er traegt den Namen, die Zeile und die Form der Anweisung, und er
+ * ist **keine** Aussage der Analyse. Darum traegt jeder so gewonnene Eintrag
+ * `origin: 'source'` und eine Evidenz mit `source: 'source-text'`, bis auf den
+ * Bildschirm durch.
+ *
+ * **Was hier ausdruecklich nicht passiert.** Es wird nicht geparst. Ein Scanner
+ * ueber Text kann eine Import-Anweisung in einem Blockkommentar oder in einem
+ * Template-String nicht von einer echten unterscheiden, und er kennt nur die
+ * Schreibweisen, die unten stehen. Beides ist der Grund, warum die Gruppe
+ * niemals "unused import" sagt: die Aussage ueber die Benutzung kommt aus den
+ * Fakten des Index, nie aus diesem Scanner, und dieser Scanner liefert nur die
+ * Liste der Namen, ueber die gefragt wird.
+ *
+ * Rein bis auf {@link fileImportsFor}, das eine Provider-Lesung braucht.

+ * The second kind is about the honest footer. A block assembled from eight
+ * symbols of which three had facts is not a description of eight symbols, and

+ * named absences and the capped note are asserted directly rather than through a

+ *
+ * Aenderungen gegenueber dem Original, beide genannt statt versteckt:
+ *
+ *  - Die Importpfade zeigen auf die ebenfalls portierten Dateien dieses
+ *    Projekts (SymbolRef, CallSite, SemanticIR und toGraphLine aus src/core/,
+ *    der Wortlaut aus ./pseudocode-strings).
+ *  - W8c: eine Zeile traegt jetzt auch, WOHIN sie fuehrt (`targetLine`,

+ *    hergibt (`behind`, aus ./step-insights.ts). Beides steht neben `text` und

+ *    (applyRefinedPseudocode) sehen genau dieselben Zeilen wie vorher.
+ *  - Statt des `ClosureDto` der Theia-RPC nimmt der Builder ein
+ *    {@link ClosureDocument}. Dieses Projekt hat keine RPC-Fassade; sein Walk
+ *    ist `src/provider/closure.ts` und liefert `nodes` (Symbol plus Hop plus
+ *    via) statt einer flachen `symbols`-Liste. Das ist dieselbe Antwort in einer
+ *    reicheren Form, und `closureDocumentOf` faltet sie auf die Form zurueck,
+ *    die der Builder liest. Der Builder bleibt damit wortgleich mit dem
+ *    Original, und die Umrechnung steht an einer Stelle statt in jedem Aufrufer.

+/**
+ * Pseudocode from semantic IR. No React, no DOM, no services.
+ *
+ * A numbered list of steps under the heading "pseudocode" is the most
+ * believable thing this product can put on a screen and therefore the easiest
+ * place in it to lie. Four rules keep it a rendering of the index.
+ *
+ * **Only a fact becomes a line.** Every step is a call site the index reported,
+ * every raise line is a raised type it reported, every environment line is a
+ * read it reported. There is no control flow here, no `if`, no `for`, no
+ * `return`: the graph does not record them, so a block that drew them would be
+ * inventing the one thing a reader would most want to trust. What is left is
+ * narrower than pseudocode usually means and is exactly what CodeAtlas knows.
+ *
+ * **Every line points somewhere.** A step, a raise and an environment read all
+ * carry a `sourceRef`, so a reader can check any of them against the code in one
+ * click. The three do not point at the same kind of place, and that difference
+ * is documented on {@link PseudocodeLine.sourceRef} rather than smoothed over: a
+ * step points at its call site inside the symbol being described, and a raise
+ * points at the site the index recorded, which is very often in the callee's
+ * file. Group and note lines carry no ref, because they are this file's own
+ * words rather than a finding.
+ *
+ * **The verb is the strategy.** `construct` when the index called the site a
+ * construction, `call` otherwise. Guessing a richer verb from the callee's name
+ * ("validates", "persists") would be the product writing the comment the code
+ * does not have.
+ *
+ * **What is missing is counted.** {@link PseudocodeHonesty} says how many of the
+ * symbols in scope contributed anything and names the ones that did not, and
+ * `capped` is true when the walk the block was built from stopped at a bound.
+ * A block assembled from ten symbols of which two had facts is not a
+ * description of ten symbols, and nothing else on screen can tell a reader that.
+ *
+ * Everything here is pure. The surface owns the fetching, the scope resolution
+ * and the refinement; this file owns what the answer looks like once the facts
+ * are in hand, which is the part worth testing without a browser.

+/**
+ * Letting the local model rephrase a deterministic block, and refusing when it
+ * did anything else.
+ *
+ * W4c ported `applyRefinedPseudocode` and left it unwired, with the note that
+ * the wiring lands with the local model. This is that wiring, and it is a thin
+ * file on purpose: the validator already decides what a legal rewrite is, and
+ * everything here does is put a prompt on one side of it and a reason on the
+ * other.
+ *
+ * ## Why a rewrite is worth doing at all
+ *
+ * The block is a list of findings in canonical vocabulary: "1. call
+ * validateUser". That is exactly right and reads like a machine. A model that
+ * turns it into "1. validate the input with validateUser" has added nothing and
+ * removed nothing, and a reader gets through it faster. The moment it adds
+ * anything, the rewrite is worthless and dangerous in the same breath, because
+ * the block's whole authority is that every line is a fact of the index.
+ *
+ * ## What is checked, and why positionally
+ *
+ * `applyRefinedPseudocode` maps line by line: same count, same order, same
+ * leading numbers, unnumbered lines still unnumbered. That is a strong check for
+ * a cheap one, and it is the only check that cannot be talked around: a model
+ * that dropped a step, merged two or renumbered anything fails it. What it
+ * cannot catch is a line that keeps its number and lies inside it, which is why
+ * the prompt forbids adding facts and why the reader can always bring the
+ * original back with one click.
+ *
+ * ## The reason is shown, never swallowed
+ *
+ * A refused rewrite produces a named reason and the original block stays on
+ * screen. A silent refusal would look exactly like a model that had nothing to
+ * say, and the difference matters: one is the guard working and the other is the
+ * sidecar being down.

+/**
+ * What lies behind a call, as far as what this window already holds says.
+ *
+ * No React, no DOM, no fetching, and above all no second server way: this
+ * module reads the graph the galaxy already loaded (`/api/layout`, one answer
+ * per project, kept in App state) and the call sites the twin already has, and
+ * from those two it says what the index records about the symbol a step calls.
+ * A step that reads "call validateId" can then also say that validateId raises
+ * ValidationError, which is the one thing the code beside the block does not
+ * show and the reader would otherwise have to go and look up.
+ *
+ * ## Four rules, and the third is the reason this file is small
+ *
+ * **Only a recorded relation becomes a note.** A note is a RAISES, a CALLS or a
+ * CONFIGURES edge the index wrote between two nodes. There is no reading of the
+ * callee's body here, no guess from its name, and no sentence assembled out of
+ * two relations that would say more together than either says alone.
+ *
+ * **A callee is matched by its qualified name and by nothing else.** The
+ * fixture of this project has two functions called `create`, in two files, and
+ * a match on the bare name would put the notes of one under the steps of the
+ * other. A call site the index resolved carries the qualified name the graph
+ * uses for the same symbol, so the join is exact or it does not happen.
+ *
+ * **What is not in memory is not fetched.** The three kinds below exist because
+ * the loaded layout answers them. Everything a reader might also want to know
+ * about a callee (what it reads, what it writes, what it does in which order)
+ * would need a `facts` request per callee, and this block is the one surface of
+ * the product that costs nothing. What is out of reach is named in
+ * {@link ENRICHMENT_MISSING} rather than quietly left out, so the next cycle
+ * starts from a list instead of from a guess.
+ *
+ * **An empty note is not an empty callee.** A step with nothing beside it is a
+ * step whose callee the loaded graph records none of these three relations for.
+ * It is not a callee that raises nothing. That sentence is
+ * {@link PSEUDOCODE_BEHIND_NOTE} and it stands behind the block's provenance
+ * mark, because a note that only appears when there is something to say cannot
+ * carry its own limit.

+ * Eine Datei fuer den Reader holen, und ehrlich sagen, was davon angekommen ist.
+ *
+ * Der Server hat keinen Endpunkt, der eine Datei ausliefert. Es gibt keinen
+ * /api/file in diesem historischen Providerpfad.
+ * Was es gibt, ist `get_code_snippet` auf einem indizierten Symbol. Der
+ * Modul-Knoten ist das Symbol, das die ganze Datei umspannt, und ueber ihn
+ * kommt der Reader an den Quelltext.
+ *
+ * Der Weg hat einen Preis und der wird hier nicht versteckt:
+ *
+ * 1. **500 Zeilen sind Schluss.** `MCP_SNIPPET_MAX_LINES` kappt jeden
+ *    Schnipsel (cbm/src/mcp/mcp.c). Der Server sagt es selbst mit
+ *    `source_clipped`. Eine laengere Datei kommt also unvollstaendig an, und
+ *    der Reader schreibt darunter, welche Zeilen fehlen und warum.
+ * 2. **Nachladen gibt es seit dem schlanken Ausgabevertrag (#1597).** Bis
+ *    dahin wurden `start_line` und `end_line` angenommen und ignoriert
+ *    (gemessen, verification/w2/reader.json unter `windowSemantics`). Seit
+ *    dem Vertrag liefert `source_mode: full` Seiten zu 500 Zeilen, und die
+ *    Antwort nennt in `next_start_line` die naechste; loadFileDocument holt
+ *    sie nacheinander und fuegt sie zusammen. Ohne `source_mode: full`
+ *    umreisst der Server jeden Container ab 200 Zeilen und schickt gar
+ *    keinen Quelltext. Einen "load more"-Knopf gibt es weiterhin nicht: die
+ *    Seiten kommen von selbst, und was nicht kommt, steht als Satz darunter.
+ * 3. **Nur, was indiziert ist.** Eine Datei ohne Modul-Knoten ist ueber diesen
+ *    Weg nicht lesbar. Der Reader sagt das, statt eine leere Flaeche zu zeigen.

+/**
+ * Monaco, eingebunden als ESM ueber Vite. Kein CDN, kein AMD-Loader.
+ *
+ * **Warum ESM und nicht der AMD-Weg aus spike/.** Der Spike lud Monaco ueber
+ * `loader.js` aus `/node_modules/monaco-editor/min/vs`. Das war fuer einen
+ * Wegwerf-Beweis richtig und fuer das Produkt falsch: der ausgelieferte Ordner
+ * ist `dist/`, und der Server bettet genau das ein, was dort liegt
+ * (scripts/embed-frontend.sh sammelt dist/ per find).
+ * Ein AMD-Loader haette verlangt, `min/vs` daneben zu kopieren und den Pfad zur
+ * Laufzeit zu raten. Als ESM-Import ist Monaco Teil des Bundles, und was Vite
+ * gebaut hat, liegt vollstaendig in dist/.
+ *
+ * **Die Importpfade sind die von 0.56, nicht die aus der alten Anleitung.**
+ * Die Vite-Rezepte im Netz schreiben `monaco-editor/esm/vs/editor/editor.api`.
+ * Die `exports`-Tabelle von monaco-editor 0.56 bildet `./*` auf `./esm/vs/*.js`
+ * ab, also loest genau dieser Pfad auf `esm/vs/esm/vs/editor/editor.api.js` auf
+ * und existiert nicht. Richtig ist `monaco-editor/editor/editor.api`. Geprueft
+ * mit `import.meta.resolve`, nicht geraten.
+ *
+ * **Die Sprachdienste fehlen mit Absicht.** Der volle Einstiegspunkt
+ * (`import * as monaco from 'monaco-editor'`) zieht die TypeScript-, JSON-,
+ * CSS- und HTML-Sprachdienste mit, also einen Typpruefer in einem Worker. Der
+ * wuerde hier ueber eine Datei laufen, die der Server bei 500 Zeilen ABGESCHNITTEN
+ * geliefert hat, und rote Wellenlinien unter Code malen, der nur deshalb
+ * unvollstaendig aussieht. Eine Lese-Oberflaeche, die Fehler erfindet, ist
+ * schlimmer als eine ohne Diagnosen.
+ *
+ * Deshalb `languages/definitions/register.all` und nicht `languages/register.all`:
+ * die aeussere Fassung zieht am Ende ihrer Liste die vier Sprachdienste mit
+ * herein, die innere sind nur die 81 Monarch-Definitionen. Faerbung ist damit
+ * rein lexikalisch und behauptet nichts. Der Preis ist benannt: JSON hat keine
+ * Monarch-Definition, weil seine Faerbung beim Sprachdienst liegt, also
+ * erscheint eine .json-Datei ungefaerbt. Ungefaerbt ist ehrlich; falsch
+ * unterringelt waere es nicht.

+ * Die Schritt-Nummern im Rand des Readers, als Monaco-Dekorationen.

+ * Das ist der Ersatz fuer `CodeAtlasStepBadgeDecorator` aus CodeAtlasIDE
+ * (theia-extensions/codeatlas-core/src/browser/step-badge-decorator.ts, Klasse
+ * ab Zeile 90). Die REGEL, welche Zeile welche Nummer bekommt, ist nicht hier:

+ * malt nur, was dort entschieden wurde. Zwei Stellen, die numerieren duerfen,
+ * waeren zwei Meinungen darueber, welcher Aufruf Schritt drei ist.
+ *
+ * Vier Entscheidungen der Vorlage sind hier unveraendert:
+ *
+ * 1. **`linesDecorationsClassName`, nicht `inlineClassName`.** Das Badge sitzt
+ *    im Rand neben der Zeilennummer und verschiebt kein einziges Zeichen des
+ *    gelesenen Quelltextes.
+ * 2. **Die Ziffer kommt aus dem Stylesheet**, ueber die numerierte Klasse
+ *    `codeatlas-step-badge-N`. Es gibt genau neun davon und es wird nie mehr
+ *    geben, also kostet das nichts und macht das Badge umfaerbbar, ohne dass
+ *    dieses Modul davon weiss.
+ * 3. **Die Spanne ist leer und liegt auf EINER Zeile.** Eine Spanne, die am
+ *    Anfang der Folgezeile endet, wuerde die Folgezeile mitdekorieren und jedes
+ *    Badge zweimal zeichnen: einmal am Aufruf und einmal an dem, was zufaellig
+ *    darunter steht.
+ * 4. **Die Zeile klebt nicht am Text.** `stickiness` steht auf
+ *    `NeverGrowsWhenTypingAtEdges`, wie in der Vorlage.
+ *
+ * Ein Unterschied zur Vorlage, und er ist eine Zeilenzaehlung, kein Verhalten:
+ * Theias `EditorDecoration` nimmt 0-basierte Positionen, Monacos `IRange` nimmt
+ * 1-basierte. `StepBadge.line` ist eine 1-basierte Graph-Zeile, geht hier also

+ * the atlas' explizite Beispiele, wie man den Chat nutzt, sonst weiss niemand,
+ * wie man es nutzt."
+ *
+ * Der alte Platzhalter nannte eine GATTUNG ("ein Kommando oder eine Frage") und

+ * etwas tun", was ein leeres Feld ohnehin schon sagt. Die Zeile hat zwei Jobs
+ * (suchen und fragen), und beide sind an ihrer Form zu erkennen, sobald man sie
+ * einmal gesehen hat: zwei Buchstaben suchen, ein `@` bindet die Frage an ein
+ * Symbol, ein Fragezeichen macht aus einer Eingabe eine Frage. Das ist genau
+ * das, was ein Beispiel zeigt und eine Gattungsbezeichnung nicht.
+ *
+ * ## Warum die Namen aus dem geladenen Index kommen muessen
+ *
+ * Ein Beispiel mit einem Symbol, das dieses Projekt nicht hat, waere eine
+ * Einladung ins Leere: der Leser tippt es ab, bekommt nichts, und lernt daraus
+ * das Falsche ueber die Zeile. Die Namen kommen darum aus dem, was der Browser
+ * schon geladen hat (den Knoten des Layouts, siehe src/search/local-suggestions.ts),
+ * und wenn nichts geladen ist, gibt es keine Beispiele: eine erfundene Liste
+ * waere schlechter als keine.
+ *
+ * ## Die Wahl ist ordinal und damit wiederholbar
+ *
+ * Nicht "der erste Knoten der Antwort": die Reihenfolge des Layouts ist die des
+ * Servers und kann sich zwischen zwei Laeufen aendern. Sortiert wird nach dem
+ * Namen, und bevorzugt wird ein Symbol, das aufrufbar ist (eine Funktion oder
+ * eine Methode), weil die beiden Fragen darunter von Aufrufen handeln. Ein

+ * Woher die Kandidaten kommen, die die Rangfolge dann ordnet.
+ *
+ * Das Vorbild ist die Kommando-Haelfte des Referenzprojekts
+ * (CodeAtlasIDE, theia-extensions/codeatlas-views/src/browser/search/search-command.ts).
+ * Uebernommen ist ihre Regel: **eine Anfrage je Wort, nicht eine je Phrase.**
+ * Kein Symbol in irgendeinem Repository heisst "user validation"; wer die
+ * Phrase als eine Anfrage stellt, bekommt nichts und haelt das fuer eine
+ * Aussage ueber den Code. Die Vereinigung der Wort-Antworten ist die Menge,
+ * ueber die dann gerankt wird, damit ein Symbol, das nur das zweite Wort
+ * traegt, ueberhaupt eine Chance hat.
+ *
+ * Drei Abweichungen vom Vorbild, alle drei erzwungen und alle drei benannt:
+ *
+ * 1. **BM25 statt Namensmuster.** Der Server beantwortet die flache,
+ *    maschinenlesbare Suchform nur ueber `query` mit BM25-Rang
+ *    (src/provider/rpc-client.ts). Die name_pattern-Form kommt als nach
+ *    Modulen gruppierte Anzeigeform zurueck. Fuer die Rangfolge unten ist das
+ *    unerheblich: sie rechnet ihre eigene Ordnung ueber Woerter und benutzt
+ *    den Rang der Engine an keiner Stelle.
+ * 2. **25 Kandidaten je Wort statt 40.** Ein Wort, das mehr als 25 Symbole
+ *    trifft, grenzt nichts mehr ein; die BM25-Form liefert ihre besten zuerst,
+ *    also ist der Schnitt der obere Rand und nicht ein zufaelliges Praefix.
+ * 3. **Fan-in kommt aus dem Layout, wenn eines geladen ist.** Das
+ *    Referenzprojekt fragt dafuer eine zweite Runde Komplexitaetswerte ab.
+ *    Dieses Produkt hat die Zahl schon im Haus: `in_calls` steht an jedem
+ *    Knoten der Galaxie. Ohne geladenes Layout hat jeder Kandidat kein
+ *    Fan-in, und das aendert nur, wer bei Gleichstand vorne steht.

+ * Vorschlaege aus dem, was ohnehin schon geladen ist.
+ *
+ * ## Warum es sie gibt
+ *
+ * Nutzerbefund vom 2026-08-29: die Suchvorschlaege erscheinen zu langsam. Der
+ * Weg war bis dahin: tippen, 200 ms warten, ein Wort je Anfrage an den Server,
+ * dann die erste Zeile. In dieser Zeit ist der Bildschirm leer, obwohl der
+ * Browser die Antwort auf einen guten Teil der Frage schon im Speicher hat.
+ *
+ * Zwei Quellen liegen dort und kosten keinen Serverweg:
+ *
+ *  1. **Die Knoten des Layouts.** Die Galaxie laedt sie beim Start; jeder traegt
+ *     Name, qualifizierten Namen, Datei und Deklarationszeile.
+ *  2. **Die Dateien des Baums.** Der Explorer laedt sie beim Start ebenfalls,
+ *     und ein Leser, der `userService` tippt, meint oft genau die Datei.
+ *
+ * ## Was diese Vorschlaege sind und was nicht
+ *
+ * Sie sind **vorlaeufig** und sagen das auch: die Zeile traegt eine Marke, und
+ * sobald die Antwort des Index da ist, steht dort das Ergebnis der Suche. Ein
+ * lokaler Vorschlag ist keine Behauptung ueber den Index, sondern eine Aussage
+ * ueber das, was dieses Fenster schon weiss. Er ist trotzdem nie eine
+ * Attrappe: jede Zeile fuehrt an eine Stelle, die dieses Fenster oeffnen kann.
+ *
+ * Gerankt wird mit **derselben** Funktion wie die Antwort des Servers
+ * (`rankHits`). Eine eigene Ordnung fuer die vorlaeufigen Zeilen waere die
+ * teuerste Art, den Sprung zu bauen, den dieser Zyklus abschaffen soll: die
+ * Liste wuerde beim Eintreffen der Antwort nicht ersetzt, sondern umsortiert.
+ *
+ * ## Die eine Abweichung, und warum sie eine ist
+ *
+ * `isNavigable` (semantic-search.ts) wirft Treffer weg, die nach ihrer eigenen
+ * Datei heissen, und Treffer mit der Art `module`. Der Grund dort ist richtig:
+ * die Suchantwort des Servers enthaelt Datei- und Modulzeilen als Dubletten der
+ * Symbolzeilen, und ein Modul hat keine Deklaration, zu der man springen
+ * koennte. Hier ist die Lage eine andere: der Baum liefert Dateien, keine
+ * Dubletten, und diese Oberflaeche oeffnet eine Datei mit einem Klick, genau so
+ * wie der Explorer es tut. Eine Datei bekommt deshalb den Stamm ihres Namens
+ * (`userService` fuer `src/services/userService.ts`) und die Art `unknown`: der
+ * Index hat sie nicht als Symbol eingeordnet, und etwas anderes zu behaupten
+ * waere eine erfundene Symbolart.

+/**
+ * Search by meaning, without asking anybody what a meaning is.
+ *
+ * ## Why there is no model behind this
+ *
+ * "Semantic search" normally means an embedding, which means a second thing
+ * that can leave the machine and a ranking nobody can explain when it is wrong.
+ * This product already has one place where a byte may leave and one reason for
+ * it to, and neither is a search box. So the ranking here is arithmetic over
+ * words: the query is split, the candidate names and the paths they live in are
+ * split the same way, and what is scored is the overlap. Every hit can be
+ * explained in one clause, which is what {@link RankedHit.matched} carries and
+ * what the picker prints under each row.
+ *
+ * That is a weaker promise than an embedding makes and it is one this product
+ * can keep. A reader typing "user validation" is not asking for a vector; they
+ * are asking which of the things in this repository are about users and about
+ * validating, and a repository names those things after what they do.
+ *
+ * ## The signals, and why each one is here
+ *
+ * **A name is worth more than a path.** `validateUser` is about validating
+ * users; `toUser` in `userService.ts` is about users because of where it lives,
+ * which is a weaker claim about the same word.
+ *
+ * **An exact word beats a prefix beats a shared stem.** "user" and "users" are
+ * the same word to a reader and not to a string comparison, and "validation"
+ * and "validate" share seven letters and a meaning. Each of those is worth
+ * something and each is worth less than the one above it, so a symbol that
+ * carries the reader's word exactly is never beaten by one that nearly does.
+ *
+ * **Covering two words beats covering one twice.** A query of two words is two
+ * questions, and a symbol that answers both is what the reader is looking for.
+ * This is a bonus rather than a tier, deliberately: a symbol that answers one
+ * word perfectly and lives in the right file is a better answer than one that
+ * answers both words faintly, and a hard tier would rank them the other way.
+ *
+ * **Exported beats internal.** A reader searching a codebase is looking for
+ * something they can reach from elsewhere. A helper that happens to share a
+ * word is a worse answer to that question, and test code is a worse one still.
+ *
+ * **Fan-in breaks ties, and then the name does.** Two symbols with identical
+ * word overlap are separated by how much of the repository reaches them, which
+ * is the index's own measurement of which one matters more. The qualified name
+ * is the last resort, so the order is total: two runs over one index produce the
+ * same list, which is what lets a picker be photographed and a driver assert on
+ * the top five.
+ *
+ * Nothing in this file talks to anything. It is given candidates and it returns
+ * an order, so the whole ranking is unit tested against hand written hits with
+ * no engine, no workspace and no window.

+/**
+ * Das Einstellungen-Panel: welches Modell antwortet, wie man ein anderes
+ * bekommt, und alles, was Rechenzeit kostet.
+ *
+ * Nutzerwunsch vom 2026-08-29, woertlich: "2D/3D oder sowas sollte immer
+ * zentral in einem Settings-Menue drin sein, nicht alles auf einer Oberflaeche,
+ * wegen Rechenleistung falls jemand keine so starke Maschine hat." Und Martin
+ * am selben Tag: "Man bietet in der UI das Feature so an, dass man sich von zum
+ * Beispiel Hugging Face selber ein Modell aussuchen kann, das wird dann im
+ * local cache gedownloaded."
+ *
+ * Fuenf Entscheidungen, und keine davon ist Geschmack:
+ *
+ * 1. **Overlay ueber der Editorflaeche, nach dem Muster der Hilfe.** Dasselbe
+ *    Muster wie src/help/HelpOverlay.tsx: eine eigene Ebene, der Kasten scrollt
+ *    selbst, Escape schliesst. Ein Panel in der rechten Spalte waere eine
+ *    Tabelle mit sechs Zahlenspalten in einer 440 Pixel breiten Saeule.
+ * 2. **Aus heisst aus, auch hier.** Dieses Panel hat kein eigenes `fetch`. Was
+ *    es ueber den Sidecar weiss, bekommt es als Props von App.tsx, wo die eine
+ *    Stelle steht, die ueber das Fragen entscheidet, und der Aktualisieren-Knopf
+ *    ruft genau dieselbe Probe, damit er im selben Zaehler landet. Solange das
+ *    lokale Modell aus ist, gibt es diesen Knopf nicht, und das Panel steht
+ *    trotzdem da und erklaert sich.
+ * 3. **Keine Zahl ohne Herkunft.** Die vier Angaben des laufenden Modells
+ *    tragen im Tooltip die Anfrage, aus der sie stammen, genau wie in
+ *    SidecarPanel.tsx. Die sechs Vorschlaege tragen ihre Eval-Zahlen, und ein
+ *    Unit-Test haelt jede davon gegen verification/w5/eval.json und die ADR
+ *    (src/settings/model-catalog.test.ts).
+ * 4. **Kein Fortschrittsbalken.** Diese Oberflaeche kann keinen Download sehen:
+ *    sie hat kein Backend, startet keinen Prozess und schreibt keine Datei. Sie
+ *    zeigt den fertigen Befehl, sagt darueber, wohin er laedt, und liest die
+ *    Liste danach neu. Ein Balken ueber eine Uebertragung, die ein anderer
+ *    Prozess faehrt, waere eine Animation und keine Messung.
+ * 5. **Jede Leistungseinstellung misst sich selbst.** Ein Fenster vor der
+ *    Aenderung, eine Beruhigungsphase, ein Fenster danach, und davor das
+ *    Rauschband dieser Maschine. Liegt der Unterschied darin, sagt das Panel
+ *    genau das. Gemessen wird nicht hier, sondern in der Szene
+ *    (src/galaxy/frame-rate.ts): eine zweite Rechnung fuer dieselbe Zahl waere
+ *    eine zweite Wahrheit.
+ *
+ * Der ganze Text steht im Katalog (src/i18n/messages.ts), wie bei der Hilfe.
+ * Hier steht nur, in welcher Reihenfolge er dasteht und woran er haengt.

+/**
+ * Die sechs Vorschlaege, mit den Zahlen, die dieses Projekt an ihnen gemessen
+ * hat, und dem Aufruf, mit dem man einen davon holt.
+ *
+ * ## Warum eine Liste im Quelltext und keine Abfrage
+ *
+ * Es gibt nichts abzufragen. Hugging Face kennt Millionen Repositories und
+ * dieses Fenster erreicht keines davon: die Oberflaeche ist per Vorgabe
+ * abgeschottet (lokale Modellvorschlaege). Was sie anbieten kann, ist das, was dieses
+ * Projekt selbst GEMESSEN hat, und das sind genau diese sechs Dateien: 44
+ * goldene Fragen, Temperatur 0, Seed 42, eine Maschine, ein Tag
+ * (verification/w5/eval.json, Tabelle in docs/adr/0001-modellwahl.md).
+ *
+ * ## Warum jede Zahl hier gegen ihre Quelle geprueft wird
+ *
+ * Eine Zahl im Quelltext, die niemand gegen ihre Quelle haelt, ist eine
+ * Behauptung. src/settings/model-catalog.test.ts liest verification/w5/eval.json
+ * und docs/adr/0001-modellwahl.md und vergleicht jeden Eintrag dieser Tabelle
+ * Feld fuer Feld: Trefferquote, Zitattreue und Tempo gegen die Aufzeichnung des
+ * Laufs, die Bytes gegen die Groessenangabe der ADR, und jede Repo-Kennung
+ * gegen ihre Quellen-URL in der ADR.
+ * Verschiebt sich eine Zahl in der Quelle, faellt dieser Katalog um, statt
+ * still weiter etwas anderes zu behaupten.
+ *
+ * ## Was diese Liste ausdruecklich NICHT ist
+ *
+ * Sie ist keine Rangliste des Feldes und keine Aussage darueber, was auf einer
+ * anderen Maschine passiert. Die Eval hat gemessen, was sie messen konnte; was
+ * ein 9B-Modell auf einem groesseren Rechner tut, hat niemand gemessen, und der
+ * Katalog behauptet darueber nichts (docs/adr/0001-modellwahl.md). Er ist die
+ * Auskunft, die ein Leser bekommt, bevor er selbst entscheidet, und das freie
+ * Feld daneben ist die Zusicherung, dass er nicht auf diese sechs festgelegt
+ * ist.

+ * Also zweierlei, und beides ohne Hover:

+ *    wie schon beim Griff des Antwort-Panels aus W7c, nur mit einer
+ *    Trefferflaeche, die eine Maus auch bei schneller Bewegung erwischt.
+ *  - **Eine Marke in der Mitte** (`::after`): ein kurzer Balken in Phosphor,
+ *    quer zur Linie. Er ist das Zeichen, das aus einer Trennlinie einen Griff
+ *    macht, und er ist DA, bevor jemand hinfaehrt. Alle vier Griffe tragen
+ *    dieselbe Marke: ein Produkt, in dem vier Grenzen ziehbar sind, die
+ *    niemand sieht, hat vier Grenzen weniger als es glaubt.

+ * Was W7c hier gebaut hatte und wo es jetzt steht:
+ *
+ * 1. **Das Panel ist eine Spalte aus zwei Teilen**: Kopf und Verlauf. Nur der
+ *    Verlauf scrollt. Der Kopf mit der Kontext-Auswahl bleibt darum beim
+ *    Scrollen stehen, ohne dass er dafuer `position: sticky` braucht: er liegt
+ *    gar nicht erst im scrollenden Kasten. Unveraendert, und weiterhin
+ *    dieselbe Zusicherung mit einem Mechanismus weniger, der schiefgehen kann.
+ * 2. **`overflow: hidden` am Panel**, damit eine zu klein gezogene Flaeche
+ *    ihren Inhalt nicht in die Kommandozeile schiebt. Unveraendert.
+ * 3. **Der Griff an der oberen Kante** ist der Griff der Zone geworden
+ *    (`.atlas-splitter`, data-testid atlas-split-explain). Er tut dasselbe,
+ *    kann dasselbe (Maus, Tastatur, Doppelklick, Gedaechtnis ueber den Reload)
+ *    und tut es fuer alle fuenf Reiter statt nur fuer diesen einen.
+ * 4. **Eingeklappt bleibt eine Zeile stehen**, die sagt, was noch da ist. Das
+ *    macht jetzt der eingeklappte Streifen der Zone, und er macht es fuer jeden
+ *    Reiter (`.atlas-explain-note`).

+/*
+ * Jeder Kasten, der mehr traegt als er zeigt, sagt es an seiner Kante.
+ *
+ * Der Befund kam von den Beweisbildern der Legende (Bernhard, 2026-08-29), aber
+ * er gehoert nicht der Legende allein: die Bildlaufleiste dieser Plattform
+ * liegt ueberlagernd und ist im Ruhezustand unsichtbar. Ein Panel, dessen
+ * Inhalt unten weitergeht, sieht darum aus wie eines, dessen letzte Zeile
+ * mitten im Wort endet. Das Lesbarkeits-Gate misst diesen Fall seit W9-1
+ * (tools/lib/readability.mjs, Regel c) und hat ihn in vier weiteren Flaechen
+ * gefunden: im Twin, im Fluss-Overlay und im BUG-Assistenten.
+ *
+ * Die Antwort ist eine Regel und keine vier: ein Schimmer an der Kante, hinter
+ * der es weitergeht. Er kommt ohne eine Zeile TypeScript aus und ist trotzdem
+ * bedingt, und dieser Kunstgriff ist der Grund fuer die vier Ebenen:
+ *
+ *  - Die beiden UNTEREN Ebenen sind der Schimmer selbst, am Kasten befestigt
+ *    (`scroll`): sie liegen immer an seiner Ober- und Unterkante.
+ *  - Die beiden OBEREN Ebenen sind Deckel in der Farbe des Grundes, am INHALT
+ *    befestigt (`local`): sie wandern mit ihm. Steht der Inhalt oben an, liegt
+ *    der obere Deckel genau ueber dem oberen Schimmer und loescht ihn; ist
+ *    unten nichts mehr, deckt der untere Deckel den unteren.
+ *
+ * Uebrig bleibt genau die Aussage, um die es geht: ein Schimmer steht dort, wo
+ * wirklich noch etwas ist. Alle vier Ebenen sind Hintergrund, liegen also
+ * hinter dem Text und verdecken kein Zeichen.
+ *
+ * Die Legende der Galaxie ist nicht dabei: sie traegt seit W9-1 ihren eigenen
+ * Verlauf und dazu eine Marke, die die Richtung nennt (GalaxyPanel,
+ * Entscheidung 12). Zwei Kanten uebereinander waeren eine zu viel.

+/**
+ * The step card, under the reader and over the command line.

+ * Layout: a header with a step count and a chain of
+ * shaded blocks, then the step's title, then two or three sentences, then the
+ * keys as buttons. Two things about it are decisions rather than drawing.
+ *
+ * **It sits in the editor column, not over it.** The card is where the walk is
+ * explained and the editor beside it is what the walk is explaining; a card that
+ * covered the code would make the reader choose between the two. It pushes the
+ * editor up instead, keeping the explanation and source visible together.
+ *
+ * **Every key is also a button.** The keys are the fast path for somebody who
+ * has both hands on the keyboard, and the buttons are what makes the same four
+ * moves discoverable and reachable for somebody who does not know them yet. The
+ * bracketed key is written into the button's own label, so the two can never
+ * drift apart.
+ *
+ * **The fourth action can be off, and says so instead of hiding.** `[d] diagram`
+ * draws the flow of the step's symbol, and a step that points at a file has no
+ * symbol to draw. The button stays where it is, dimmed and disabled, and its
+ * tooltip says which of the two it is. Removing it on those steps would move the
+ * other three buttons under the reader's hand from step to step, and it would
+ * turn "this step has no symbol" into "this product has no diagram".
+ *
+ * Purely presentational, like the chrome and the search window: what the steps
+ * are and where the reader is are decided by App.tsx, and this file draws them.
+ * That is what lets the whole card be proven in jsdom.

+/**
+ * The reading order a workspace is put into, and the four properties it stands

+ *
+ * **Determinism.** Two runs must produce the same bytes and so must two
+ * machines. The suite proves that by generating twice from inputs shuffled into
+ * a different order and comparing the serialised documents, which is the only
+ * comparison that catches an ordering that happens to be stable on this machine
+ * because a Map preserved an insertion order.
+ *
+ * **Cycles.** Import cycles are ordinary, and a topological sort has no answer
+ * for one. What matters is not that the generator survives them but that it
+ * survives them by a stated rule, records what it dropped, and still places
+ * every file exactly once.
+ *
+ * **Ordering.** The point of the whole feature: on the fixture's dependency
+ * graph, what everything rests on comes before what rests on it. The assertion
+ * is written the way the acceptance criteria are written, on config and types
+ * against routes and the server.
+ *
+ * **Grouping and honesty.** A step's role and its sentences are evidence: a path
+ * segment, or a layer the index assigned. The suite pins the fact that a step
+ * says which, and that a file the index holds no exported symbol in gets a file
+ * step rather than an invented symbol.

+/**
+ * The getting-started tour: a workspace put into the order somebody could read
+ * it in.
+ *
+ * The question this answers is the one nobody can answer on their first day in
+ * a repository: where do I start, and what has to make sense before the next
+ * thing will. The index already holds the answer, in the import relation. A
+ * file that imports another cannot be understood before it, so a topological
+ * sort of the file-level import graph is a reading order, and it is a reading
+ * order that was derived rather than opinionated.
+ *
+ * ## Five properties carry this file
+ *
+ * **Deterministic, with nothing to seed.** Two runs over one index produce
+ * byte-identical output, and so do two machines and two checkouts of the same
+ * repository at different paths. Everything here is a pure function of the
+ * paths, the edges and the summary it was handed: the ready set of the Kahn
+ * sort is drained in path order rather than in the order the engine returned
+ * rows, every list is sorted before it is read, and no clock, no random source
+ * and no absolute path is consulted anywhere.
+ *
+ * **Cycles are broken by a stated rule, not by luck.** Import cycles are
+ * ordinary in real code, and a topological sort has no answer for one. When the
+ * sort stalls, the edge whose `(from, to)` pair is lexicographically smallest
+ * among the ones still holding files back is dropped, and the sort continues.
+ * The rule is arbitrary, which is exactly why it is written down and why every
+ * dropped edge is recorded in the document's provenance.
+ *
+ * **A role is evidence, never a guess about behaviour.** A step says "its path
+ * names it as configuration" or "the index places its group in the entry
+ * layer", and stops. It never says what a file does. The generator has read no
+ * source text and is in no position to.
+ *
+ * **A step points at a symbol only when the index named one.** The exported
+ * symbols the summary flagged are the candidates; the earliest declared one in
+ * a file is the representative. A file the index holds no exported symbol in
+ * gets a file step, which opens the file at its first line, because pointing a
+ * reader at an arbitrary line would be inventing a decision.
+ *
+ * **The tour is bounded.** A repository of two thousand files does not have a
+ * two thousand step tour. Past {@link MAX_TOUR_STEPS} the walk is sampled at an
+ * even stride over the dependency order, which keeps the first file, the last
+ * file and the shape of the order in between.
+ *
+ * ## Provenance
+ *
+ * The idea of deriving a heuristic onboarding tour from a project's own
+ * structure, rather than asking a model to write one, is ported in concept from
+ * Understand-Anything (MIT). No source code is shared; see THIRD_PARTY.md.

+ * The generator in tour-generator.ts is pure and knows nothing about a provider.
+ * In the reference project the two reads that feed it sit in a Theia backend
+ * (`intelligence-server-impl.ts`, `generateTour`); here they sit in the browser,
+ * because that is where the provider is. The shape of the call is the same one:
+ * the whole-project summary supplies the files, the layers, the groups and the
+ * exported symbols, the dependency sweep supplies the edges the order is built
+ * from, and the generator is handed plain data.
+ *
+ * Two differences from the reference are worth naming rather than discovering.
+ *
+ * **Nothing is written.** The reference writes the document into
+ * `.codeatlas/tours/` and hands back a DTO with the path. This surface has no
+ * workspace to write into, so the document lives for as long as the walk does. A
+ * regenerated walk is byte-identical to the one before it, which is what made
+ * the artefact worth committing there and is what makes it worth trusting here.
+ *
+ * **No engine version is recorded.** The reference asks the engine binary for
+ * one. This backend's /rpc surface does not offer a version, so the field stays
+ * absent rather than being filled with the frontend's own build number, which
+ * would answer a question about the analysis with a fact about the UI. The
+ * provider makes the same refusal in `engineInfo`.
+ *
+ * **A project whose index holds no files is refused.** An empty walk is
+ * indistinguishable from a walk of a project whose analysis failed, and offering
+ * one would tell a reader their repository has nothing in it.

+/**
+ * The Bug Wizard: the way in the index expects, the way a recording took, and
+ * the difference between them.
+ *
+ * Four steps, in this order, and none of them optional. The anatomy is the
+ * reference project's (CodeAtlasIDE,
+ * codeatlas-views/src/browser/traces/bug-wizard-widget.tsx) and so is the reason
+ * for each one:
+ *
+ * **Choose the symbol.** Adopted from whatever the twin is showing, because
+ * somebody who opens this panel is already looking at the function that
+ * misbehaved. Changed through the same search the rest of the surface uses, so
+ * there is one answer to "which symbol is this about" rather than two that can
+ * drift apart.
+ *
+ * **The expected path.** Upstream chains from the index, labelled as a reading
+ * of the index and never as a claim that any of it ran. A walk that stopped at
+ * its bound says so, because a chain that was cut looks exactly like a chain
+ * that ended.
+ *
+ * **The observed path.** What the analysis backend hands back about those calls,
+ * with the count, the run label and when it was last seen. With nothing to hand
+ * back this is the honest empty state: the sentence that claims nothing, the
+ * command that feeds a run in, the format of one, and the one sentence about
+ * what this backend can and cannot answer afterwards.
+ *
+ * **Where they differ.** Two lists, never one number, with their own headings
+ * and their own sentences. Both empty is its own sentence too.
+ *
+ * Purely presentational, like the other overlays here: what to read is App.tsx's
+ * business, what the lists mean is bug-paths.ts's, and this file draws them.
+ *
+ * ## What a click does, and what the panel does not do
+ *
+ * Every name here is a name and never a stored reference; the click hands the
+ * hop back and the resolution happens then, against this index. And the wizard
+ * publishes nothing on its own: a reader comparing two paths has not asked the
+ * reader, the twin and the galaxy to retarget under them. Only an explicit click
+ * on a hop navigates.

+/**
+ * The way in the index expects, the way a recording took, and the difference
+ * between them.
+ *
+ * Written to the specification of `bugPaths` in CodeAtlasIDE
+ * (codeatlas-core/src/common/trace-protocol.ts, `BugPathsDto` and the three
+ * bounds; codeatlas-views/src/browser/traces/bug-wizard-widget.tsx for what the
+ * four steps do with it). It is a reimplementation rather than a port, and the
+ * reason is the whole content of this header: there, the observed calls live in
+ * a file CodeAtlas keeps itself and can be read whole. Here they live in the
+ * analysis backend, and the backend answers a narrower question than the one the
+ * reference asks.
+ *
+ * ## What this backend will and will not say about a recording
+ *
+ * Observed calls are stored by `ingest_traces` in `observed_calls`, keyed by the
+ * pair of qualified names (cbm/src/mcp/mcp.c, `handle_ingest_traces`). There is
+ * exactly one way to read them back, and it is not a listing:
+ * `cbm_atlas_attach_observed` (cbm/src/ui/http_server.c) hangs an `observed`
+ * object on a hop of an answer that was computed from the *static* graph, and
+ * the two routes that call it are the only two that ever carry one.
+ *
+ * **GET /api/trace** takes `project`, `from`, `to`, `mode` and an optional
+ * `guards`. `from` and `to` are a qualified name or `#<node id>`; `mode` is
+ * `calls` (CALLS edges) or `data` (DATA_FLOWS edges, which the TypeScript
+ * analysis does not write, so this file always asks for `calls`); `guards=1`
+ * adds the branch conditions, which this panel does not use. The answer is a
+ * breadth-first *shortest* path with `reachable`, `explored`, `hops` and a
+ * `path` array, and each entry from the second onwards may carry `observed`
+ * `{count, label, last_seen}` for the call from the entry before it.
+ *
+ * **GET /api/flow** takes `project`, `id` and the same optional `guards`, and
+ * answers one ranked entry-to-terminal walk as `steps`, each with its `parent`
+ * index. The same `observed` objects are hung on the pairs
+ * `(steps[step.parent], step)`. **GET /api/flows** takes `project` alone and
+ * lists the walks with their ids.
+ *
+ * The consequence is exact and it is stated here because it decides what the
+ * fourth step of the wizard can honestly claim: **a recorded call is only ever
+ * readable where the index also records the call.** A pair that ran and that the
+ * index has no relation for is stored by the engine and cannot be asked for
+ * again through either route, because there is no static hop to hang it on.
+ *
+ * So the two divergence lists mean this, and the panel says so in as many words:
+ *
+ *  - `staticOnly`: a call on a chain the index draws into the target that no
+ *    reading of a recording came back for. "Expected, never observed."
+ *  - `runtimeOnly`: a call a recording holds that is not on any of those chains.
+ *    Each row additionally carries {@link BugPathEdge.indexRecordsCall}, asked
+ *    of the index at the time the row is built, so the reader is told which of
+ *    the two things it is: a call the index knows and that simply is not on the
+ *    way in, or a call the index has no relation for at all. The second is the
+ *    reference's meaning of the list; with this backend it can be reported when
+ *    it appears and cannot be discovered by looking.
+ *
+ * ## The three readings, and their bounds
+ *
+ * **Upstream chains** come from the index, one `callsIn` per chain head, level by
+ * level: who calls the target, who calls them. {@link BUG_PATH_DEFAULT_DEPTH}
+ * hops by default and {@link BUG_PATH_MAX_CHAINS} chains, both the reference's
+ * numbers, and both bounds are reported through `truncated` rather than being
+ * quietly applied: a chain that was cut looks exactly like a chain that ended.
+ *
+ * **Traces** are asked once per chain, from the chain's head to the target. That
+ * is the shortest static path between the two, which is not always the chain
+ * itself; where they differ, the observation still belongs to the pair the
+ * server named, and this file keys everything on the pair rather than on a
+ * position in a list.
+ *
+ * **Flows** are the reading that can see beside and below the target. A trace
+ * into the target only ever annotates calls on the way in, so a recording that
+ * went on somewhere after the target would be invisible to it; the ranked walks
+ * carry those hops, and {@link BUG_PATH_MAX_FLOWS} of them are read.
+ *
+ * ## Nothing here holds a symbol reference
+ *
+ * A node of a trace or a flow carries a name and a file and no qualified name,
+ * and what a recording carries is whatever somebody's recorder wrote. So every
+ * row of this document is a name, and {@link resolveHop} looks it up in the
+ * index at the moment of the click, the way the reference's `resolveSymbolNamed`
+ * does. Publishing a `SymbolRef` without a `nodeId` would tell the rest of the
+ * product that a perfectly well indexed symbol is not indexed.

+ * Die Antwortformen von /api/trace, /api/flows und /api/flow, gelesen statt

+ * Dieselbe Rolle wie src/provider/rpc-schemas.ts fuer die Werkzeuge: hier wird
+ * gepruefte Form aus unbekanntem JSON, und nichts weiter. Kein Produktvokabular,
+ * kein Urteil darueber, was ein Ergebnis bedeutet. Was die Felder heissen,
+ * heissen sie im C-Quelltext des geclonten Servers; die Uebersetzung in die

+ * cbm/src/ui/http_server.c (`cbm_atlas_attach_observed`, das jeder Antwort ihre
+ * `observed`-Objekte anhaengt).
+ *
+ * Zwei Eigenheiten, die man sonst raten muesste:
+ *
+ * 1. **Ein Knoten traegt keinen qualifizierten Namen.** Er traegt `id`, `name`
+ *    und meistens `file_path`. Der Index wird deshalb ueber das Paar aus Datei
+ *    und Namen wieder angesprochen und nicht ueber eine Kennung, die es in der
+ *    Antwort nicht gibt.
+ * 2. **`observed` steht am Ziel-Knoten, nicht an einer Kante.** Der Server
+ *    heftet es an den Schritt und meint damit die Kante von dessen Vorgaenger
+ *    (`path[i-1]` beim Trace, `steps[step.parent]` beim Flow). Wer es als

+/**
+ * Das SEMANTIC_TWIN-Panel: dieselbe IR, vier Tiefen, und keine Behauptung ohne
+ * Beleg daneben.
+ *
+ * Diese Datei ist JSX und sonst nichts. Was gesagt wird, entscheidet
+ * `src/twin/render-model.ts`, portiert aus CodeAtlasIDE; was hier steht, ist
+ * die Frage, wie es aussieht. Der Schnitt ist derselbe wie im Referenzprojekt
+ * (twin-modes.tsx, twin-sections.tsx, evidence-popover.tsx) und aus demselben
+ * Grund: sobald ein Renderer anfaengt, selbst zu entscheiden, was eine Tiefe
+ * zeigt, koennen zwei Tiefen ueber dieselbe Zeile verschiedener Meinung sein.
+ *
+ * Die Regeln, die aus der Vorlage unveraendert gelten:
+ *
+ *  1. **Eine leere Sektion sagt trotzdem etwas.** Der Leer-Satz ist fuer jede
+ *     Sektion ein eigener Befund ("Nothing in the indexed workspace calls this
+ *     symbol"), nie ein Achselzucken.
+ *  2. **Ein Fakt, der keine direkte Lesung ist, traegt einen Marker**, und der
+ *     Marker traegt den ganzen Satz als `title`. Ein farbiger Punkt ohne Satz
+ *     waere Dekoration.
+ *  3. **Jede Ueberschrift und jede Zeile traegt den Beleg-Knopf**, ausser sie
+ *     behauptet gar nichts ueber den Code. Die zwei Linsen, die es als
+ *     Ueberschrift vor den Fakten gibt, tragen einen leeren `factPath`, und ein
+ *     Beleg-Knopf ueber einer Behauptung, die CodeAtlas nicht aufgestellt hat,
+ *     waere ein Angebot, das ins Leere fuehrt.
+ *  4. **Eine Zeile mit Ziel ist ein `<button>`**, eine ohne ist es nicht. Was
+ *     man anklicken kann, muss man auch mit der Tastatur erreichen koennen; was
+ *     man nicht anklicken kann, darf nicht so aussehen.
+ *
+ * Seit W5c zeichnet dieses Panel den Flow-Erklaerer nicht mehr selbst. Der
+ * flow()-Kopf bleibt, wo er war, und oeffnet jetzt das Overlay ueber der
+ * Editorflaeche (src/pseudocode/FlowOverlay.tsx). Der Grund ist ein Befund und
+ * keine Vorliebe: der Kasten sass in einer 440 Pixel breiten Spalte zwischen
+ * Kopfzeile und Detailstufen-Regler und verschwand hinter ihnen, sobald das
+ * Bild breiter wurde als die Spalte.
+ *
+ * Zwei Unterschiede zur Vorlage, beide genannt statt versteckt:
+ *
+ *  - **Kein Popover, ein aufklappbarer Block.** Die Vorlage positioniert die
+ *    Belege in einem `div` neben dem Knopf. Hier stehen sie unter der Zeile.
+ *    Der Inhalt ist derselbe (Relation, Ort, Strategie, Urheber plus
+ *    Index-Generation); was wegfaellt, ist die Positionierung, und die war im
+ *    Referenzprojekt schon ausdruecklich kein Framework.
+ *  - **Keine Codicons.** Diese Oberflaeche liefert die Schrift nicht aus. Der
+ *    Name aus `SECTION_ICONS` steht als `data-icon` an der Ueberschrift, damit
+ *    die portierte Tabelle nicht zur toten Zeile wird; getragen wird die
+ *    Bedeutung von der Ueberschrift daneben, so wie in der Vorlage auch.

+ *     Off means: no button, and the line beneath says the level is complete

+ *     A silent refusal looks exactly like a model with nothing to say, and the
+ *     difference between those two is the difference between a guard that works
+ *     and a sidecar that is down.

+# Semantic IR fixture provenance
+
+Copied byte-for-byte on 2026-08-28 from Bernhard Jackiewicz's CodeAtlasIDE project,
+`theia-extensions/codeatlas-views/test/fixtures/`, by the same author.
+`tools/record-ir-fixtures.mjs` in that project recorded these files with engine 0.9.0.
+They are snapshots, not hand-maintained alternative implementations.
+
+| Files | Purpose |
+| --- | --- |
+| `create-user-ir.json` | Populates every fact family for render-model behavior tests. |
+| Ten `ir-*.json` files | Cover leaf nodes, missing callers, absent error paths and symbols shared by several services. |
+
+The recordings refer to the source project's `atlas-sample`, whose source matches
+this repository's sample. Qualified names retain their recorded
+`codeatlas-atlas-sample-<hash>` prefix and file URIs use `file:///workspace/...`.
+They do not expose the recording machine's paths.

+/**
+ * The short answer to "what do I still not know about this?".
+ *
+ * The backend already generates a full checklist: one item per callee, one per
+ * caller, one per raised type, one per environment value. For a symbol of any
+ * size that is twenty to forty items, which is the right shape for the review
+ * checklist panel and the wrong shape for a strip above the twin. A reader
+ * glancing at the twin needs to know there is work left and roughly what kind,
+ * not to read a work breakdown.
+ *
+ * So this collapses the checklist by category into at most six lines, each of
+ * which is a thing to go and do rather than a thing to go and read. Three
+ * properties are load-bearing.
+ *
+ * **It summarises, it does not re-derive.** The counts come from the checklist
+ * the backend generated, so the strip and the full panel can never disagree
+ * about how much is left. Where a sentence needs a name rather than a count,
+ * the name is read from the fact the checklist item was generated from, which
+ * is the same source.
+ *
+ * **Every line goes somewhere.** An item the reader cannot act on is an
+ * accusation. The target is taken from the checklist item when it carries one,
+ * and otherwise from the first fact of that category, so the line opens the
+ * thing it is asking about. The generator now attaches a target to every item
+ * it emits, so the fallback below is reached only for an IR built before it
+ * did; it is kept rather than deleted because a checklist item without a
+ * target is still a shape this type allows.
+ *
+ * **The percentage counts confirmations and nothing else.** It is
+ * `confirmed / total` over the checklist items themselves, never over the six
+ * collapsed lines, so the number here and the number in the checklist panel are
+ * the same number computed the same way. Visits are deliberately absent: the
+ * strip has room for one figure, and the one figure a reader would mistake for
+ * a claim of understanding must be the one that only their own confirmations

+/**
+ * The five presets, and the layout each of them means.
+ *
+ * The panel lists are not decoration around the depth and the facets: they are
+ * half of what a profile *is*. A reader who says they are here to fix a bug and
+ * a reader who says they are here to learn the codebase should not be looking at
+ * the same four panels with a different slider position, and until the panels
+ * moved with the preset they were.
+ *
+ * Two conventions run through all five.
+ *
+ * **Rank one is what the profile leads with.** Several of these panels dock to
+ * the same side, which makes them tabs of one stack where only one is visible,
+ * so the lowest rank in an area is a statement about which question this profile
+ * thinks the reader is asking first. Debugging leads with the calls, verifying
+ * leads with the checklist, architecture leads with the map.
+ *
+ * **A widget keeps its side across every profile.** The navigator is beside the
+ * twin in all five, not on the left in three of them, because a preset that
+ * threw a panel across the window on every switch would make choosing a mode
+ * feel like opening a different application.

+ * Which reader the panel is speaking to, remembered between visits.
+ *
+ * ## Why this is stored at all
+ *
+ * Until W13 the slider was a detail level, and losing it on reload was a small
+ * annoyance: the reader moved it again. It is now a statement about the person
+ * in front of the screen, and a surface that forgets who is reading and quietly
+ * goes back to the middle setting is telling that person their answer did not
+ * matter. So it is stored, and it survives the reload and the symbol change.
+ *
+ * ## Why the key carries no project
+ *
+ * Every other preference in this frontend is keyed per project
+ * (`atlas-llm:<project>`, `atlas-why:<project>`, `atlas-understanding:<project>`)
+ * because every other preference is an answer about that codebase. This one is
+ * not. A junior does not become a senior by opening a different repository, and
+ * a key per project would mean the same person answering the same question once
+ * per codebase. One key, deliberately.
+ *
+ * ## Why every doubt ends in the middle and not at zero
+ *
+ * A missing value, unreadable JSON, a storage that refuses to answer, a number
+ * outside the ladder: all of them mean "nobody has said". The fallback is the
+ * medior level, which is the one that shows the recorded facts as they are, and
+ * that is the honest thing to show someone who has not told you who they are.
+ * Falling back to the vibe coder would be guessing that a new reader is a
+ * beginner; falling back to the architect would be guessing the opposite.

+/**
+ * Letting the local model word the twin's sentences for the selected reader,
+ * and refusing when it did anything else.
+ *
+ * The same shape as `src/pseudocode/refine.ts`, on purpose and not by accident:
+ * this project already has one answer to "may a model touch a deterministic
+ * block", and a second answer with different rules would mean two different
+ * promises about the same guarantee. So the promise is repeated here word for
+ * word, and only the thing being checked is different.
+ *
+ * ## Why a rewrite is worth doing at all
+ *
+ * The sentences of a level are assembled from counts and names. "It hands work
+ * to 4 other pieces of code." is exactly right and reads like a form letter. A
+ * model that turns it into "it leans on four other pieces of code to get its
+ * work done" has added nothing and removed nothing, and the vibe coder this
+ * level exists for gets through it faster. The moment it adds anything, the
+ * rewrite is worthless and dangerous in the same breath, because the whole
+ * authority of the sentence is that every fact in it came out of the index.
+ *
+ * ## What is checked, and why positionally
+ *
+ * Line by line, same count, same order. Inside a line, the *fact tokens* have
+ * to be identical as a sequence: the same names, the same numbers, the same
+ * files, the same lines, in the same order. A fact token is a number, a dotted
+ * or slashed path, or an identifier with a capital inside it, which between
+ * them are every shape a name, a file or a figure takes in these sentences.
+ *
+ * The required sequence is derived from the built sentence itself rather than
+ * from a list somebody has to remember to fill in. That is the whole reason the
+ * check can be trusted: a builder that forgot to declare one of its facts would
+ * make the guard blind to exactly that fact, and a guard whose coverage depends
+ * on a second list is a guard with a hole in the shape of that list.
+ *
+ * What it cannot catch is a sentence that keeps every token and lies in the
+ * English between them. That is what the prompt is for, and it is why the
+ * reader can always bring the built text back with one click, and why the
+ * marker beside a reworded sentence says who worded it.
+ *
+ * ## The reason is shown, never swallowed
+ *
+ * A refused rewrite produces a named reason, the built text stays on screen and
+ * the reader is told. A silent refusal would look exactly like a model that had
+ * nothing to say, and the difference matters: one is the guard working and the
+ * other is the sidecar being down.

+/**
+ * One semantic IR, five readers looking at it. No DOM, no services, no JSX.
+ *
+ * The slider is the product's central claim, and since W13 it asks a different
+ * question. It used to ask how much to say. It now asks who is reading, and the
+ * five answers are the reader's own words: vibe coder, junior, medior, senior,
+ * architect. The claim is the same and stronger: the same recorded facts,
+ * *chosen* for the reader in front of them, with nothing invented on the way
+ * down and nothing hidden on the way up. That only survives if the five
+ * presentations are one function of the IR rather than five panels that happen
+ * to be pointed at the same symbol, which is why this module exists and why it
+ * is pure.
+ *
+ * The five, and the question each of them answers:
+ *
+ *  - **0 vibe coder**: what happens here, and why does it matter to you? One
+ *    paragraph, clickable names, no list and no jargon it can avoid.
+ *  - **1 junior**: in what order does it happen, and why? The calls in the
+ *    order the body reaches them, with the connective between them, and a word
+ *    explained the first time it is used.
+ *  - **2 medior**: what is actually written here? The recorded facts with
+ *    their jump targets and no groundwork. This one is the old technical depth,
+ *    unchanged, down to the section order.
+ *  - **3 senior**: what does this cost me? The failure paths, what is
+ *    unchecked, who depends on it, and what a change here drags with it.
+ *  - **4 architect**: what does this sit on, and where does our knowledge end?
+ *    The ground under it, what carries it, what it owes, and the limits of the
+ *    index as a first-class part of the answer rather than a footnote.
+ *
+ * Five rules run through everything below.
+ *
+ * **One reading of the IR, five shapes of it.** The medior level is
+ * `buildSections` unchanged; the other four are derived from the same sections,
+ * or from the same facts, and never from a second interpretation. A row that
+ * says `validate.ts:19` for the medior cannot say `validate.ts:21` for the
+ * architect, because there is only one place that decided.
+ *
+ * **The level changes what is said, never what is true.** The vibe coder's
+ * level spends counts and consequences where the architect's spends names, line
+ * numbers and confidences; neither is allowed to state something the other
+ * would contradict. In particular the vibe coder's level carries no qualified
+ * name and no confidence figure anywhere a reader can see one: a reader who has
+ * asked for prose has not asked to be told that a resolution scored 0.55, and
+ * showing it anyway is how a "simple" mode becomes a lying one.
+ *
+ * **No level is allowed to be empty, and no level is allowed to be silent.** A
+ * block with nothing in it says so in that reader's own words. "No error path
+ * was recorded here" is an answer to the senior's question; a blank space is
+ * not, and it is indistinguishable from a level that does not work.
+ *
+ * **Facets subtract, they never add.** A facet that is off removes its section.
+ * A facet that is on and has no answer yet renders the heading with the
+ * sentence saying so. Both are honest; silently rendering nothing for a lens
+ * the reader explicitly asked for is not.
+ *
+ * **Nothing here knows which preset is active.** The input is a
+ * {@link ResolvedPresentation}: depth, facets, terminology, callouts. That is
+ * deliberate. The moment a renderer can ask "am I in Learning" it starts
+ * growing behaviour that no slider position can reproduce, and the slider stops
+ * being the truth about what is on screen.

+/**
+ * Kein Satz des Twins verspricht ein Feature fuer spaeter.
+ *
+ * Nutzerauftrag vom 2026-08-29. Drei Saetze dieses Moduls taten es bis dahin,
+ * und jeder auf seine Art falsch:
+ *
+ *  - die Runtime-Zeile schickte den Leser zu einem Menuepunkt "Import runtime
+ *    traces", den es in dieser Oberflaeche nicht gibt, und behauptete nebenbei,
+ *    das Produkt zeige keine beobachteten Aufrufe (es zeigt sie: an den Hops des
+ *    BUG-Assistenten und im Flow);
+ *  - die Changes-Zeile behauptete, CodeAtlas lese keine Versionsgeschichte,
+ *    waehrend die Aenderungsansicht seit W4d genau das tut;
+ *  - die Effects-Zeile versprach ein "when the effect relations land", also
+ *    einen Termin auf einer fremden Roadmap.
+ *
+ * Dieser Test ist die Sperre dagegen. Er geht ueber ALLE sichtbaren Saetze
+ * dieses Moduls, nicht nur ueber die drei, weil der naechste solche Satz an
+ * einer anderen Stelle entstehen wird.
+ *
+ * ## Die Ausnahmen, und warum es genau diese sind
+ *
+ * Drei Saetze duerfen "yet" tragen, und alle drei reden ueber denselben
+ * Sachverhalt: eine Datei ist NOCH NICHT INDIZIERT. Das ist kein Versprechen
+ * ueber ein Feature, sondern eine Auskunft ueber einen Zustand, den der Leser
+ * selbst aendert, indem er das Projekt indiziert. Zwei davon stehen ausserdem
+ * unter einer eigenen Zusicherung: `absenceSentence` ist wortgleich mit
+ * `explainAbsence` des Backends (siehe Docblock dort), und ein umgeschriebener
+ * Satz waere ein stiller Bruch dieser Gleichheit.

+ * Herkunft: portiert am 2026-08-28 aus CodeAtlasIDE,
+ * /Users/bernhard/Desktop/CodeAtlasIDE/theia-extensions/codeatlas-views/src/browser/strings.ts
+ * Gleicher Urheber (Bernhard Jackiewicz).
+ *
+ * Die Quelldatei ist 2639 Zeilen lang und traegt den Wortlaut ALLER Flaechen des
+ * Referenzprojekts. Hier stehen die Exporte, die der Semantic Twin benutzt, und
+ * die stehen WOERTLICH da, samt ihrer Begruendungen: der Unterschied zwischen
+ * "keine Aufrufer" und "niemand hat nachgesehen" wird in diesem Produkt
+ * ausschliesslich vom Wortlaut getragen, und eine gekuerzte Fassung waere eine
+ * andere Aussage.
+ *
+ * Uebernommen ist genau das, was die portierten Module und das Panel dieses
+ * Projekts lesen: die Ueberschriften und Subjekte der Sektionen, ihre
+ * Leer-Saetze, die Block-Augenbrauen, die Marker der Wissenszustaende, die
+ * Absenz-Saetze in beiden Vokabularen, die Prosa der Erzaehl-Tiefe, die
+ * Beleg-Sprache, die dichten Provenienz-Bausteine, die Regler-Beschriftungen,
+ * die Runtime-Sektion, der Verstehens-Streifen und die Wegweiser-Saetze.
+ *
+ * Weggelassen wurde der Wortlaut der Flaechen, die es hier nicht gibt: Atlas
+ * Chat, die optionale KI-Verfeinerung samt Daten-Policy und Sende-Vorschau, die
+ * Review-Checkliste als Panel, der Call Navigator, die Workspace Map, die
+ * Impact-Ansicht, Onboarding und Touren, die Bug-Wizard-Diagramme, die
+ * Konzept-Erklaerungen und die "Why are you here?"-Karten. Das ist keine
+ * Auswahl nach Geschmack: zu jeder dieser Zeichenketten gehoert ein Panel, und
+ * ein Satz ueber ein Panel, das dieses Projekt nicht hat, waere hier eine
+ * Behauptung ueber eine Flaeche, die niemand sehen kann.
+ *
+ * Aenderungen an dem, was uebernommen wurde: eine, und sie ist begruendet.
+ *
+ * `CALLERS_EMPTY` weicht seit dem 2026-08-29 vom Referenz-Wortlaut ab. Das
+ * unabhaengige Audit dieses Zyklus hat eine Fixture mit dynamischem Versand
+ * ueber eine Registry gebaut und darin belegt, dass der Referenzsatz
+ * ("Nothing in the indexed workspace calls this symbol.") falsch ist: die
+ * beiden nur ueber die Registry erreichbaren Handler WERDEN im indizierten
+ * Arbeitsbereich aufgerufen, nur eben nicht ueber eine CALLS-Kante, die der
+ * Index fuehrt. Der Satz behauptete damit etwas ueber den Arbeitsbereich,
+ * waehrend seine drei Nachbarn (STEPS_EMPTY, ERRORS_EMPTY, STATE_EMPTY) die
+ * Luecke ausdruecklich dem Index zuschreiben. Eine wortgleiche Portierung
+ * eines belegt falschen Satzes waere Portierungstreue gegen die
+ * Ehrlichkeitsregel, und die Regel gewinnt. Der neue Wortlaut steht bei der
+ * Konstante, mit derselben Begruendung.
+ *
+ * Sonst keine Aenderungen ausser den Importpfaden (Facet aus der ebenfalls
+ * portierten presentation-profile.ts, CodeAtlasSymbolKind und KnowledgeState

+ * The semantic IR, arranged for reading. No React, no DOM, no services.
+ *
+ * The twin renders sections of rows, and deciding what a row says, what it
+ * points at and which citation backs it is not a rendering concern: it is a
+ * reading of the IR, and it is the part that will be reused when the depth
+ * slider starts showing more or less of the same model. Keeping it here means
+ * the next surface that wants the same content writes different JSX rather
+ * than a second interpretation of the IR.
+ *
+ * Two conventions run through the whole file.
+ *
+ * A row's `factPath` is the address of its citation inside the IR, in the same
+ * `fact` or `fact[row]` grammar the backend's evidence service parses. The
+ * providers build the evidence array in lockstep with the value array, so row
+ * `n` of a fact is backed by citation `n`; where that lockstep does not hold
+ * the popover shows nothing rather than the wrong line.
+ *
+ * A row's `siteLine` is a 1-based graph line inside the *focused symbol's*
+ * file, and a row's `target` is where clicking it navigates, which is usually a
+ * different file. Conflating the two is the bug this separation exists to
+ * prevent: a call to `validateUser` on line 24 of `userService.ts` is declared
+ * on line 19 of `validate.ts`, and both numbers are true about different files.

+/**
+ * Ein Tooltip, den diese Oberflaeche selbst zeichnet, selbst platziert und
+ * selbst messen laesst.
+ *
+ * ## Warum es ihn gibt
+ *
+ * Bis W8b erklaerte sich diese Oberflaeche mit dem `title`-Attribut, 78 Mal.
+ * Der Browser zeichnet daraus einen Kasten AUSSERHALB des Dokuments, unter dem
+ * Mauszeiger und ohne Rechteck. Zwei Folgen, und beide sind Fehler:
+ *
+ *  1. Er legt sich ueber das, was gerade unter ihm liegt. Im Screenshot des
+ *     Nutzers vom 2026-08-29 lag "76 nodes, 178 edges from /api/layout" ueber
+ *     dem Detail-Regler und ueber den Chips Logic, Calls, Data.
+ *  2. Keine Messung sieht ihn. Die Ueberlagerungsregel dieses Projekts liest
+ *     `getBoundingClientRect`, und ein nativer Tooltip hat keine. Der Fehler
+ *     war also nicht nur da, er war unsichtbar fuer jeden gruenen Beweislauf.
+ *
+ * Dieser Kasten hat beides umgekehrt: er steht im Dokument, er rechnet seine
+ * Lage (src/ui/tooltip/tooltip-model.ts), und er traegt eine Testmarke, an der
+ * ein Lauf ihn einzeln oeffnen und vermessen kann.
+ *
+ * ## Warum er in den Rumpf portiert wird und nicht neben den Ausloeser
+ *
+ * Weil er sonst die Geschwisterordnung seines Ausloesers aendert. Ein Kasten,
+ * der nur manchmal zwischen zwei Chips steht, ist ein Layout, das beim
+ * Beruehren zuckt, und CSS-Regeln, die auf Nachbarschaft zeigen, wuerden
+ * gelegentlich danebengreifen. Im Rumpf liegt er fest positioniert und
+ * beruehrt die Anordnung von nichts.
+ *
+ * ## Die Tastatur ist keine Zugabe
+ *
+ * Er oeffnet bei Hover UND bei Fokus, und Escape schliesst ihn. Ein Tooltip,
+ * den nur die Maus oeffnet, waere fuer die Haelfte dieser Oberflaeche gar
+ * nicht da: sie ist an der Tastatur entworfen (PLAN Abschnitt 4). Escape haengt
+ * in der EINFANGENDEN Phase am Fenster, damit er vor den Griffen der grossen
+ * Flaechen drankommt: wer einen Tooltip offen hat und Escape drueckt, meint
+ * ihn, und nicht den Bereich dahinter. Die Griffe dahinter pruefen
+ * `defaultPrevented` und lassen die Taste dann liegen.
+ *
+ * ## Der Klick-Griff, und warum ihn der Ausloeser holen muss
+ *
+ * Hover und Fokus sind zwei Wege, und auf einem Zeigegeraet ohne Hover ist
+ * keiner davon einer: wer tippt, hovert nicht, und wer die Maus nicht auf ein
+ * Zeichen legt, um zu sehen ob etwas passiert, erfaehrt nie, dass dort etwas
+ * steht. Ein Ausloeser, der nichts anderes tut als diesen Satz zu tragen, ist
+ * damit unerreichbar, und wenn er ausserdem ein `<button>` ist, verspricht er
+ * eine Handlung, die es nicht gibt (Befund W10-1, `npm run check:promises`).
+ *
+ * Dafuer gibt es {@link HintHold}: ein Klick HAELT den Kasten fest, ein zweiter
+ * Klick, Escape oder ein Klick daneben laesst ihn los. Der Griff wird aber
+ * nicht jedem Ausloeser aufgedraengt, sondern nur dem, der ihn nimmt (die
+ * Funktionsform von `children`). Der Grund ist der Absatz weiter unten an
+ * `onClick`: an einem Schalter, der etwas TUT, ist der Satz nach dem Druecken
+ * die Beschreibung von etwas, das schon passiert ist, und meist ausserdem
+ * falsch. Wuerde ein Klick dort festhalten statt zu schliessen, bliebe genau
+ * der veraltete Satz stehen, den der Beweislauf aus W9 im Bild gefunden hat.
+ * Ein Griff fuer die stummen Ausloeser, kein Griff fuer die handelnden: das ist
+ * EINE Regel an EINER Stelle und gilt fuer alle Hints dieser Oberflaeche.
+ *
+ * ## Wo er NICHT hingehoert
+ *
+ * Ein Tooltip ist kein Ersatz fuer eine fehlende Beschriftung. Wo ein `title`
+ * nur den sichtbaren Text wiederholt hat, ist er in W8b ersatzlos entfallen;
+ * wo eine Flaeche ihren Grund IM FELD sagen muss (die gedimmten Reiter des
+ * Erklaeren-Bereichs), sagt sie ihn weiterhin dort.

+/**
+ * Wo ein Tooltip stehen darf, und was er dabei nicht verdecken darf.
+ *
+ * ## Der Befund, gegen den diese Datei geschrieben ist
+ *
+ * Nutzerbefund vom 2026-08-29 mit Screenshot: der Tooltip "76 nodes, 178 edges
+ * from /api/layout" lag ueber dem Detail-Regler und ueber den Chips Logic,
+ * Calls und Data. Der Nutzer dazu: "ich hab damals schon in Auftrag gegeben,
+ * dass sich Dinge ueberlappen, was uncool ist."
+ *
+ * Die Ursache war nicht ein falsch gesetzter Kasten, sondern eine ganze
+ * Gattung: es waren native `title`-Tooltips, 78 davon im Produktivcode. Der
+ * Browser zeichnet sie AUSSERHALB des Dokuments, unter dem Mauszeiger. Sie
+ * haben kein Rechteck, das `getBoundingClientRect` liefern koennte, und darum
+ * hat keine einzige Ueberlagerungsmessung dieses Projekts sie je gesehen. Es
+ * gab also 78 Flaechen, die sich ueber beliebigen Inhalt legen konnten, und
+ * null Messung darauf.
+ *
+ * Ein eigener Tooltip im Dokument loest beide Haelften: er hat ein Rechteck,
+ * also kann ein Beweislauf ihn sehen, und er kann RECHNEN, wo er hin soll,
+ * statt unter dem Zeiger zu erscheinen. Diese Datei ist die Rechnung. Sie steht
+ * ohne React und ohne DOM da, damit jede Zahl ohne Browser pruefbar ist.
+ *
+ * ## Die Regel
+ *
+ * Ein Tooltip darf nicht verdecken, was der Leser gerade BRAUCHT. Das ist enger
+ * als "nichts verdecken": ein Tooltip liegt per Bauart ueber etwas, sonst
+ * muesste die Oberflaeche ihm Platz freihalten, den sie nicht hat. Geschuetzt
+ * ist darum genau dreierlei:
+ *
+ *  1. sein eigener Ausloeser (ein Tooltip, der den Knopf verdeckt, den man
+ *     gerade beruehrt, nimmt dem Zeiger sein Ziel),
+ *  2. Regler und Eingabefelder (das ist der Fall aus dem Screenshot),
+ *  3. die Beschriftungen der Sektion, in der der Ausloeser steht (`data-hint-keep`).
+ *
+ * Alles andere darf ein Tooltip ueberdecken: Fliesstext, den man nach dem
+ * Loslassen wieder sieht, ist kein Verlust.
+ *
+ * ## Warum zwoelf Kandidaten und nicht vier
+ *
+ * Vier Seiten mal drei Ausrichtungen auf der Querachse. Mit nur vier Seiten
+ * scheitert die Regel an genau den Stellen, an denen sie gebraucht wird: ein
+ * Ausloeser am oberen Rand einer Spalte hat unter sich seine eigene Werkzeug-
+ * leiste und ueber sich das Fensterende, und "unten, links ausgerichtet" ist
+ * dann besetzt, waehrend "unten, rechts ausgerichtet" frei danebenliegt. Die
+ * Ausrichtung ist billig zu rechnen und macht den Unterschied zwischen einer
+ * Regel, die haelt, und einer, die eine Ausnahmeliste braucht.

+/**
+ * What the reader came here to do, and what the panel does with the answer.
+ *
+ * The question is asked once per project and the answer is used once, at the
+ * moment it is given: it sets how much the twin shows and which lenses it shows
+ * it through, and then it is remembered only so the question is not asked again.
+ * Nothing downstream reads the intent back. That is the reference project's own
+ * rule (`codeatlas-views/src/browser/why-widget.tsx`) and it is worth keeping:
+ * an intent that stayed live would become a mode, and a mode is a second product
+ * hiding inside the first.
+ *
+ * ## The order of the cards
+ *
+ * Order of a working day, not alphabetical and not by how much of it is built.
+ * Something is broken, then something has to change, then somebody needs to
+ * know the shape of the place, then somebody already knows where they want to
+ * start. A reader scanning four cards reads them in that order anyway.
+ *
+ * ## The wording
+ *
+ * Every visible string in this file is checked by the browser run against a list
+ * of words this product does not use about its reader. It is a reading tool for
+ * people who already write software; the vocabulary of a course would describe
+ * a different relationship than the one this surface has.
+ *
+ * ## All four cards open something
+ *
+ * Until W4b, "Hunt a bug" and "Scope a change" set their profile and said so in
+ * their own sentence, because a card that quietly did half of what it promises
+ * is the failure this project is written against. Both now open the panel they
+ * name (src/traces/BugWizard.tsx and src/impact/ImpactPanel.tsx), so the
+ * sentence is gone rather than reworded: a note saying "this does less than it
+ * says" that stayed after it stopped being true would be the same failure with
+ * the sign flipped. The `stub` field is kept on the type because the next card
+ * that lands before its panel does will need it.

+ *   on although this backend records no runtime relation, because the reader
+ *   asked for it and the twin says `unsupported` in the section itself. Turning
+ *   it off for them would answer their question by hiding it.
+ * - `change` takes the `verification` reading: technical depth with data, tests
+ *   and changes, which are the three that say what a change would break.
+ * - `understand` takes the `understanding` reading: one step shallower, with
+ *   logic, calls and tests, which is the reading the topsort walk is written for.
+ * - `entry` keeps the workbench default. Somebody who names their own starting

+ * Die Bruecke: eine Ereignisdatei, gelesen und als Server-Sent-Events
+ * weitergereicht.
+ *

+ *   node tools/agent-bridge.mjs --replay fixtures/agent-events/w11a-replay.jsonl
+ *
+ * ## Was sie ist, und was sie ausdruecklich nicht ist
+ *
+ * Sie **liest**. Sie oeffnet die Ereignisdatei zum Lesen, verfolgt, was
+ * angehaengt wird, und schickt jede vollstaendige Zeile weiter. Sie schreibt
+ * nie in die Datei, sie legt sie nicht an, sie loescht sie nicht, und sie nimmt
+ * kein Ereignis von aussen entgegen: es gibt keine Route, die etwas
+ * hinzufuegt. Damit kann die Oberflaeche die Aufzeichnung nicht veraendern, und
+ * das ist der Grund, aus dem die eigenen Bewegungen des Lesers ("you") gar
+ * nicht erst hierher kommen.
+ *
+ * Sie spricht **nur Loopback**. Sie lauscht auf 127.0.0.1, sie weist jede
+ * Verbindung ab, die nicht von dort kommt, und sie erlaubt als Ursprung nur
+ * 127.0.0.1 und localhost. Ein Netzwerkdienst ist sie damit nicht.
+ *
+ * Sie ist **nicht noetig**. Laeuft sie nicht, laeuft die Oberflaeche weiter und
+ * sagt, dass keine Quelle verbunden ist, samt dem Befehl, der die Bruecke
+ * startet. Ein leerer Graph, der wie Ruhe aussieht, waere die Behauptung, es
+ * arbeite gerade niemand.
+ *
+ * ## Zwei Betriebsarten, und warum die zweite existiert
+ *
+ * **live**: die Datei wird verfolgt. Neue Zeilen gehen sofort hinaus. Das ist
+ * der Betrieb.
+ *
+ * **replay**: die Datei wird einmal gelesen und danach steht der Takt still,
+ * bis jemand ihn setzt (`POST /replay/advance`). Ohne diese Naht muesste ein
+ * Beweislauf auf die Wanduhr warten, und eine Aufzeichnung mit echten
+ * Zeitabstaenden dauert Minuten; mit ihr ist derselbe Ablauf in Sekunden
+ * gefahren und, was mehr zaehlt, in jedem Lauf an derselben Stelle. Die
+ * Zeitstempel werden dabei auf die Gegenwart geschoben und behalten ihre
+ * Abstaende: eine Ansicht, die "vor drei Sekunden" sagt, soll nicht "vor acht
+ * Monaten" meinen. Was verschoben wurde, steht in jedem Ereignis (`ts_recorded`)
+ * und im Willkommensereignis (`mode: "replay"`), damit die Oberflaeche einen
+ * Wiedergabelauf nie als Gegenwart ausgeben kann.
+ *
+ * ## Wiederaufnahme
+ *
+ * `GET /events?since=<lauf>:<nummer>,<lauf>:<nummer>` schickt nur, was hinter
+ * den genannten Nummern liegt. Der Klient merkt sich die zuletzt gesehene
+ * Nummer je Lauf und nennt sie beim Wiederverbinden; was dazwischen verloren
+ * ging, sieht er an der Luecke in den Nummern und sagt es.
+ *
+ * ## Das Format einer Zeile
+ *
+ *   ts    Millisekunden seit 1970
+ *   agent Anzeigename
+ *   run   Kennung eines Laufs
+ *   seq   fortlaufend je Lauf
+ *   phase "start" oder "end"
+ *   tool  Werkzeugname
+ *   path  optionaler Pfad, repo-relativ
+ *   lines optionaler Bereich [von, bis]
+ *   detail  optionaler Befehl oder Suchbegriff
+ *   intent  optionale Selbstauskunft des Agenten
+ *
+ * Unbekannte Felder werden durchgereicht und nicht als Fehler behandelt: eine
+ * Quelle, die mehr weiss, soll nicht daran scheitern, dass sie es sagt. Eine
+ * Zeile, die kein JSON ist, wird gezaehlt und uebersprungen.

+/*
+ * Die Eval als Regressionstest: die zwei Sieger noch einmal, gegen die
+ * aufgezeichneten Zahlen.
+ *
+ *   node tools/eval-check.mjs [--out verification/w6/evalcheck.json]
+ *
+ * Befund 9 des unabhaengigen Audits vom 2026-08-29: PLAN Abschnitt 6.5 verlangt
+ * die Eval "als Regressionstest", und sie war ein Handlauf. `npm run eval:llm`
+ * faehrt sechs Modelle ueber 44 Fragen und dauert ein paar Minuten; kein Gate
+ * rief sie, und die Abnahmetests lasen ausschliesslich die aufgezeichnete Datei.
+ * Eine Aenderung am Context-Compiler, die die Zitattreue senkt, waere damit in
+ * keinem Lauf aufgefallen: verification/w5/eval.json haette weiter 0.932
+ * behauptet, weil sie es im Maerz gemessen hat.
+ *
+ * Dieser Lauf ist die fehlende Haelfte. Er ist ABSICHTLICH nicht die ganze Eval.
+ *
+ * ## Was er faehrt und was nicht
+ *
+ * Er faehrt die ZWEI Sieger (Klasse A und Klasse B, gelesen aus eval.json, nicht
+ * hier hartkodiert) ueber ALLE Fragen, mit denselben Karten aus demselben
+ * Compiler, Temperatur 0 und Seed 42. Er faehrt NICHT die vier Verlierer: die
+ * Frage "welches Modell ist das beste" ist im ADR beantwortet und wird nicht bei
+ * jedem Release neu gestellt. Die Frage, die hier gestellt wird, ist eine andere
+ * und viel engere: **liefert der Compiler von heute mit dem Modell von damals
+ * noch dieselben Zahlen.** Vier weitere Modelle wuerden diese Frage nicht besser
+ * beantworten, sondern nur die Laufzeit verdreifachen, bis niemand mehr das Gate
+ * faehrt.
+ *
+ * ## Wie verglichen wird, und warum die zwei Seiten verschieden streng sind
+ *
+ * **passRate mit Toleranz (+-0.05).** Die Trefferquote haengt an den Wortlauten
+ * eines Modells, und dieselbe Bitte kann bei gleicher Temperatur ueber eine
+ * andere llama.cpp-Fassung oder einen anderen Rechner ein Wort anders fallen.
+ * Eine Toleranz von 0.05 sind bei 44 Fragen gut zwei Fragen: genug fuer das
+ * Rauschen, zu wenig fuer eine Regression, die diesen Namen verdient.
+ *
+ * **Zitattreue hart auf der Grenze.** Sie ist keine Frage des Wortlauts, sondern
+ * eine Frage des Formats: entweder jede Behauptungszeile traegt ihr [K], oder
+ * nicht. Ein Vertrag, der eine Toleranz bekommt, ist kein Vertrag. Die Grenze
+ * ist dieselbe wie in tools/lib/eval-bounds.mjs.
+ *
+ * Der Vergleich laeuft in BEIDE Richtungen, aber nur die eine ist ein Fehler:
+ * eine gestiegene Trefferquote wird gemeldet und laesst den Lauf gruen. Ein Gate,
+ * das eine Verbesserung rot faerbt, ist ein Gate, das zu Verschlechterungen
+ * erzieht.
+ *
+ * ## Ports und Prozesse
+ *
+ * C-Server ab 4360, Modelle ab EVAL_PORT_FLOOR (4400). Der Produktport 4141
+ * bleibt frei: dieser Lauf startet dort nichts und redet mit niemandem dort.
+ *
+ * Gezaehlt werden am Ende NUR die Ports, die dieser Lauf selbst belegt hat.
+ *
+ * Bis zum 2026-08-29 stand 4141 in derselben Liste wie die eigenen Ports, und
+ * jeder Prozess darauf zaehlte als Prozessrest DIESES Laufs. Am 2026-08-29 hat
+ * das den Release-Gate-Lauf rot gefaerbt, obwohl beide Vergleiche in Toleranz
+ * lagen: auf 4141 lief der Sidecar des Eigentuemers, dazu ein Browser mit einer
+ * offenen Verbindung dorthin. Zwei Prozesse, die dieser Lauf weder gestartet
+ * hat noch beenden darf, und ein Ergebnis, das etwas anderes behauptete als es
+ * gemessen hatte.
+ *
+ * Ein Pruefer raeumt auf und zaehlt, was er selbst gestartet hat, und sonst
+ * nichts. Die Belegung von 4141 steht darum weiter im Bericht, aber als eigenes
+ * Feld (`sidecarPort`) und zur Kenntnis: sie sagt etwas ueber den Rechner und
+ * nichts ueber diesen Lauf, und sie faerbt ihn nicht.
+ *
+ * Nebenbei genau gesagt, weil der Name es verschweigt: `countListeners` fragt
+ * `lsof -ti tcp:<port>` und bekommt damit jeden Prozess mit einem Socket auf
+ * dem Port, Server wie Client. Fuer die eigenen Ports ist das die richtige
+ * Strenge (wer dort noch haengt, haengt an etwas, das dieser Lauf geoeffnet
+ * hat); fuer einen fremden Port ist es die falsche Frage.

+/*
+ * The head-to-head: forty-four golden questions, six candidates, one card set
+ * each, temperature zero and a fixed seed.
+ *
+ * This is the measurement PLAN paragraph 5 promises ("der Sieger der eigenen
+ * Eval schlaegt den Benchmark-Ruf") and the one the model ADR was left open
+ * for. It answers one question and refuses to answer any other: **given the
+ * same compiled cards, which of these six models phrases the most answers
+ * correctly without inventing anything.**
+ *
+ * ## What is held constant, and why that is the whole design
+ *
+ * Every model sees the SAME cards for a question of its class. The cards are
+ * compiled once per model class (A gets the 3000-token budget, B gets 8000),
+ * before any model starts, by the product's own compiler through
+ * tools/lib/compiler-bundle.mjs. Nothing about the graph, the classifier, the
+ * recipe or the card wording can therefore differ between two candidates, which
+ * means a difference in score is a difference between the models and not
+ * between two runs of an index.
+ *
+ * Temperature zero and seed 42 are set in src/chat/chat-client.ts, which is the
+ * same file the product's chat uses. Non-thinking is the per-model switch
+ * measured in src/compiler/prompt-contract.ts.
+ *
+ * ## What is scored
+ *
+ * Three things per question, and an answer has to survive all three to pass:
+ *
+ *  1. every expected substring appears in the answer,
+ *  2. no forbidden substring appears,
+ *  3. the citation contract holds: every claim line carries a [K], and every
+ *     cited card was actually handed over.
+ *
+ * Rule three is scored separately as well, because it is the one that decides
+ * whether this product can ship a model at all. A model that is right and
+ * uncited is a model whose answers nobody can check.
+ *
+ * ## Citation compliance counts the answers it could read, and says how many it could not
+ *
+ * Since W10, `citationCompliance` is the share of MEASURED checks, and
+ * `citationUnmeasured` names how many were not measured. The difference is the
+ * finding from W7c (see `measured` in src/compiler/answer-contract.ts): an
+ * answer of exactly one line that the token ceiling cut off leaves the check
+ * with nothing to look at, and zero violations out of zero lines is not
+ * compliance. Counting it as clean would flatter the model; counting it as a
+ * violation would score the ceiling. It falls out of the rate, and the number
+ * that fell out stands beside the rate so nobody reads a recommendation off a
+ * sample that quietly shrank. `passRate` is untouched by this: an answer that
+ * could not be measured for citations still misses its expected substrings and
+ * still fails there.
+ *
+ * ## The bounds are a gate, not a remark
+ *
+ * Since 2026-08-29 (audit finding 6) this run ENFORCES the two bounds the ADR
+ * has always claimed: a class winner under passRate 0.6 or under citation 0.9
+ * ends this run with a non-zero exit and a named reason. The numbers live in
+ * tools/lib/eval-bounds.mjs, they are written into the report as `bounds`, and
+ * tools/eval-check.mjs holds the recorded winners to the same two lines. Before
+ * that they existed only inside a frozen acceptance test, which reads a file and
+ * cannot stop a run: a compiler change that sank the citation rate would have
+ * crowned a winner anyway and reported success.
+ *
+ * ## Two questions are answered without a model, on purpose
+ *
+ * `honest-01-de` and `honest-02-en` name nothing the index holds, so the
+ * compiler produces no cards and the chat returns the agreed sentence without
+ * sending a request. That is the product's behaviour, so it is measured as the
+ * product's behaviour; the count is reported per model as
+ * `deterministicAnswers` so nobody has to work out why six models agree exactly
+ * twice.
+ *
+ * ## Ports
+ *
+ * The C-server takes a free port from 4310 up. Each model takes a free port
+ * from 4400 up: the product port 4141 stays free throughout, so the UI keeps
+ * working and a crashed run cannot leave a model sitting on the port the
+ * sidecar manager polls.
+ *
+ * Run: node tools/eval-llm.mjs [--dry] [--only <id-prefix>] [--models a,b]
+ *   --dry    compile the cards and score nothing: no model is started
+ *   --only   run a subset of the questions, by id prefix
+ *   --models run a subset of the candidates, by key

+ * Der Fresh-Clone-Check: steht dieses Repository fuer sich?
+ *
+ *   node tools/freshclone-check.mjs [--out verification/w6/freshclone.json]
+ *
+ * Ein Projekt, das nur auf der Maschine gruen ist, auf der es entstanden ist,
+ * ist nicht fertig, sondern eingerichtet. Der Check baut die Situation nach, in
+ * der jemand anders es zum ersten Mal anfasst: klonen, Abhaengigkeiten
+ * installieren, Abnahmetests fahren, Unit-Suite fahren. Vier Antworten, und
+ * jede ist eine eigene Zeile im Ergebnis.
+ *
+ * ## Vier Entscheidungen, die man sonst raten muesste
+ *
+ * **Der Klon kommt aus `file://` und nie aus dem Netz.** Die Quelle ist dieses
+ * Verzeichnis. Ein Klon von einer Weiterleitung waere ein Test der
+ * Weiterleitung, und dieser Lauf soll ohne Aussenwelt auskommen.
+ *
+ * **Der Arbeitsbaum wird ueber den Klon gelegt, und das steht im Ergebnis.**
+ * Ein Klon traegt, was committet ist. Die Dateien eines laufenden Zyklus sind es
+ * noch nicht: der Commit kommt nach dem Beweis und nicht davor. Der Check
+ * kopiert deshalb genau die Pfade, die `git status` als geaendert oder neu
+ * meldet, und listet sie unter `workingTreeOverlay` auf. Ohne diese Liste waere
+ * die Aussage "ein frischer Klon ist gruen" eine Aussage ueber den Stand von
+ * gestern; mit ihr ist sie eine ueber den Stand, der gleich committet wird.
+ *
+ * **`npm ci --offline` zuerst, und ein Fehlschlag wird gemessen statt
+ * abgebrochen.** Offline heisst: alles kommt aus dem lokalen npm-Cache. Fehlt
+ * dort ein Paket, ist das ein Befund ueber diese Maschine und keine Aussage
+ * ueber das Repository; er steht als `cacheMiss` im Ergebnis, und der Lauf
+ * versucht es danach noch einmal ohne die Offline-Klammer. Auch dieser zweite
+ * Versuch bekommt kein Netz zu sehen, wenn keins da ist; er wuerde dann
+ * genauso scheitern, und beide Ausgaben stehen im Bericht.
+ *
+ * **Playwright laedt keine Browser nach.** `PLAYWRIGHT_SKIP_BROWSER_DOWNLOAD=1`
+ * ist gesetzt, denn weder die Abnahmetests noch die Unit-Suite starten einen
+ * Browser: das tun die Beweislaeufe, und die laufen nicht im Klon. Ohne die
+ * Variable versuchte das Installationsskript einen Download, und ein Check, der
+ * ins Netz greift, um Netzfreiheit zu beweisen, waere sein eigener Gegenbeweis.
+ *
+ * ## Die eine Selbstbezueglichkeit, und wie sie aufgeloest wird
+ *
+ * Der Abnahmetest W6a liest verification/w6/freshclone.json, also genau die
+ * Datei, die dieser Lauf schreibt. Im Klon muss sie darum schon liegen, bevor
+ * die Abnahmetests dort laufen. Der Check legt sie deshalb VOR dem Testlauf im
+ * Klon ab, mit den zu diesem Zeitpunkt bereits gemessenen Werten (`cloneOk`,
+ * `npmCiOk`, `unitPass`) und mit `scaffoldPass: true` als der einen Behauptung,
+ * die der Testlauf im selben Moment prueft. Ist die Suite im Klon rot, wird
+ * `scaffoldPass` als `false` geschrieben und dieser Lauf ist nicht gruen. Es
+ * gibt also keinen Weg, auf dem ein `true` in der Datei landet, ohne dass die
+ * Suite im Klon wirklich gruen war.

+ * Nachpruefung der Durchsicht: K19-lines (Behavior und Service map ohne

+ * stehen), K25 von einem frischen Profil aus und K26-identity (gleicher Text
+ * von zwei Stellen wird zweimal voll gesendet, ein Zaehler traegt seine
+ * Stelle).
+ *
+ * Beschriftungen und Kamera haengen von der Groesse der Zeichenflaeche ab. K20,
+ * K21 und K25 laufen darum zweimal: mit 1600x1000 und in der Ansicht des
+ * Handtests (1494x728, Chat offen), in der die leeren Behavior-Kaesten
+ * auffielen.
+ *
+ * Es startet keinen Server und schreibt nichts in das Protokoll des Servers:

+ * navigator.sendBeacon (die letzte Sendung beim Verlassen einer Seite, die am
+ * Routing vorbeigeht) bleibt in der Seite. So landen die Pruefsitzungen nicht

+ *
+ * One check per item. Each drives the flow the plan describes, measures it in the page
+ * (DOM text and boxes, the messages sent to the model worker, the agent lamp) and prints
+ * PASS or FAIL with the measured values. Screenshots go to <out>/<K-id>/ with an
+ * index.md that names each image; model outputs go to <out>/<K-id>/outputs.json.
+ *
+ * It starts no server. It needs a running server with the UI and a browser profile in
+ * which the local model is cached for this origin (Cache Storage is per origin).
+ * With --with-download the last K24 check deletes that cached model and downloads it again (network
+ * access to Hugging Face), to switch the project while the download runs; the cache is full again after it.

+ * Browser-Pruefung der Galaxy-Korrekturen aus dem Handtest vom 03.10.2026
+ * (graph-ui/verification/call-feedback-2026-10-02/KORREKTURPLAN.md, K2, K3,
+ * K5, K6, K8, K9, K13).
+ *
+ *   node tools/handtest-fixes-galaxy.mjs --origin http://127.0.0.1:4371 \
+ *        --out /tmp/handtest-galaxy [--only K2,K9] [--project django-demo]
+ *
+ * Jede Pruefung faehrt genau den Ablauf aus dem Korrekturplan, misst in der
+ * laufenden Seite und druckt PASS oder FAIL mit den Messwerten. Die Bilder
+ * liegen je Punkt unter <out>/<K>/, daneben eine index.md, die jedes Bild und
+ * das, was es zeigt, auffuehrt. Gegen einen Stand ohne die Korrekturen
+ * gefahren, sollen die Pruefungen fehlschlagen; das ist der Vorher-Beweis.
+ *
+ * Es startet keinen Server. Gebraucht wird ein Ursprung mit UI und /rpc, etwa
+ * tools/lib/static-proxy.mjs vor einem laufenden Server.
+ *
+ * Nach dem Review der Korrekturen kamen dazu: die Auswahl bleibt bei Zurueck
+ * auf dieselbe Wurzel und beim Abbruch (K2/K8), die Leiste passt auch bei
+ * 1.494, 1.440, 1.366 und 1.280 px mit offenem Chat, ohne etwas abzuschneiden
+ * (K3), die Hierarchie bei zwei Ebenen traegt Namen (K5), das Laden zaehlt
+ * Seite fuer Seite und warnt vorher (K8), und der Quelltext nennt die echte
+ * letzte Zeile (K13).
+ *
+ * Nach der Vollstaendigkeitspruefung kamen dazu: bei zwei Ebenen steht kein
+ * Aufgerufener eines Tests in der Spalte "incoming", gemischt Erreichtes steht
+ * im beschrifteten Band, jedes Kantenschild traegt Art und Pfeil, und ueber
+ * 150 Knoten behalten Wurzel und direkte Nachbarn ihre Namen (K5); die Namen
+ * im Mini-Galaxy von Explore liegen nicht aufeinander (K12); Bereich und
+ * gezeigte Zeilen enden bei der echten letzten Zeile (K13); Zurueck und Vor
+ * tragen Worte, solange die Leiste Platz hat (K2).
+ *
+ * Der Browser laeuft ohne Fenster (`headless`), mit dem Kanal `chromium`:
+ * nur so zeichnet WebGL auf der GPU und nicht in SwiftShader, das die
+ * Galaxie von 5.000 Knoten so langsam macht, dass der Baum in Explore nicht
+ * fertig wird. `--headed` zeigt das Fenster.

+/**
+ * Der Scan nach hartkodierten sichtbaren Strings im App-Chrome.
+ *
+ * Er gehoert an eine Stelle, weil ihn zwei Aufrufer brauchen: der Unit-Test
+ * src/i18n/messages.test.ts, der ihn bei jedem `npm run test:unit` fahren
+ * laesst, und tools/style-gate.mjs, das seine Zahl nach
+ * verification/w6/stylegate.json schreibt. Zwei Fassungen derselben Regel
+ * waeren zwei Gelegenheiten, eine davon weicher zu machen.
+ *
+ * ## Warum der TypeScript-Parser und nicht ein regulaerer Ausdruck
+ *
+ * Ein Ausdruck ueber den Rohtext kann einen Satz in einem Kommentar nicht von
+ * einem Satz in der Oberflaeche unterscheiden, und dieser Quelltext besteht zu
+ * einem guten Teil aus Begruendungen. Der Parser sieht den Unterschied: ein
+ * JSX-Textknoten ist Text auf dem Bildschirm, ein Docblock ist es nicht.
+ * TypeScript liegt ohnehin als devDependency da und wird hier nur zum Lesen
+ * benutzt (`createSourceFile`), nicht zum Uebersetzen.
+ *
+ * ## Was als sichtbare Fundstelle gilt
+ *
+ * Fuenf Stellen, und jede davon ist eine, an der ein Zeichen wirklich auf dem
+ * Bildschirm landet:
+ *
+ *  1. **JSX-Textknoten.** `<span>EXPLORER</span>`.
+ *  2. **String- oder Template-Literale direkt in einer JSX-Klammer.**
+ *     `{'no file open'}`.
+ *  3. **Literale in einem sichtbaren Attribut**: `title`, `placeholder`,
+ *     `aria-label`, `alt`, `label`, `headline`, `note`, `empty`, `message`,
+ *     `source`. Auch geschachtelt, also in einem Bedingungsausdruck oder einem
+ *     Template innerhalb des Attributs.
+ *  4. **Eigenschaften eines Objektliterals, die als Beschriftung gelesen
+ *     werden**: `title`, `label`, `value`, `message`, `hint`, `note`, `detail`,
+ *     `headline`, `placeholder`, `empty`. Darueber laufen die Menuepunkte, die
+ *     Chips der Kopfzeile und die Chips der Statusleiste.
+ *  5. **Saetze, die ein Zustandssetzer bekommt**, dessen Name auf `Message`,
+ *     `Detail`, `Hint` oder `Name` endet. Darueber laufen die Meldungen, die
+ *     App.tsx an Reader, Twin, Suche, Assistent und Fuehrung gibt.
+ *
+ * ## Was ausdruecklich NICHT zaehlt, und warum
+ *
+ * Die Ausnahmen sind Teil der Aussage und stehen darum im Ergebnis, nicht nur
+ * hier im Kopf:
+ *
+ *  - **Literale ohne Buchstaben.** `'>'`, `'▾'`, `' › '`, `'●'`, Ziffern,
+ *    Leerraum. Sie sind Zeichen und keine Saetze, und ein Katalogeintrag fuer
+ *    ein Groesserzeichen waere eine Uebersetzung ohne Sprache.
+ *  - **Ein einzelner Buchstabe.** Das `x` am Tab-Schliesser. Aus demselben

+ * spricht von "harten Grenzen 0.6/0.9", und die standen bis dahin ausschliesslich
+ * im eingefrorenen Abnahmetest (tests/scaffold/w5b.test.mjs). Ein Abnahmetest
+ * liest eine aufgezeichnete Datei; er kann einen Lauf nicht anhalten. `npm run

+ *  - `tools/eval-check.mjs` prueft die zwei aufgezeichneten Sieger erneut gegen
+ *    dieselben Zahlen,
+ *  - `tools/lib/eval-bounds.test.mjs` beweist die Regel an erfundenen
+ *    Ergebnissen, ohne ein Modell zu laden.
+ *
+ * ## Warum es zwei Zahlen sind und nicht eine
+ *
+ * Die Trefferquote sagt, wie oft die Antwort stimmt; die Zitattreue sagt, ob man
+ * es nachsehen kann. Ein Modell mit hoher Trefferquote und schlechter Zitattreue
+ * hat fuer dieses Produkt nichts geleistet: seine richtigen Antworten sind von
+ * seinen falschen nicht zu unterscheiden. Darum ist die Zitattreue die haertere
+ * Schranke (0.9 gegen 0.6), und darum sind es zwei Bedingungen und nicht ein

+/**
+ * Das Lesbarkeits-Gate: liegt an dieser Stelle der Strecke etwas uebereinander,
+ * ragt etwas aus seinem Kasten, und was passiert, wenn man bis ans Ende
+ * scrollt?
+ *
+ * Bernhards Schlussanforderung vom 2026-08-29, und sie ist keine Kosmetikfrage.
+ * Vier Wellen Rueckmeldung in W5c handelten davon, dass Beschriftungen sich
+ * ueberlagerten, dass ein Kasten hinter einer Zeile verschwand und dass eine
+ * Leiste in ihre Nachbarn wuchs. Jedes Mal war der Befund an einem gruenen
+ * Testlauf nicht zu sehen und an einem Screenshot sofort. Dieses Modul macht die
+ * Frage messbar, damit sie an JEDEM Halt gestellt wird und nicht nur dort, wo
+ * gerade jemand hinsieht.
+ *
+ * ## Was gemessen wird
+ *
+ * **Kandidaten** sind sichtbare Elemente mit eigenem Text: mindestens ein
+ * direktes Textkind mit Zeichen darin, ein Rechteck mit Flaeche, nicht
+ * `display:none`, nicht `visibility:hidden`, nicht durchsichtig. Ein Element,
+ * das nur andere Elemente enthaelt, ist kein Kandidat: sein Rechteck ist die
+ * Summe seiner Kinder und wuerde jedes von ihnen ueberlagern.
+ *
+ * **Sichtbar heisst wirklich sichtbar.** Gerechnet wird nicht mit dem Rechteck
+ * des Elements, sondern mit dem, was davon nach allen Kaesten darueber uebrig
+ * bleibt: das Rechteck wird an jedem Vorfahren geschnitten, dessen `overflow`
+ * nicht `visible` ist, und zuletzt am Fenster. Bleibt nichts uebrig, ist das
+ * Element nicht auf dem Bildschirm und zaehlt nicht mit. Ohne diesen Schnitt
+ * waere jeder gescrollte Bereich eine Fundgrube falscher Befunde: eine Zeile,
+ * die im Twin nach oben aus dem Sichtfenster gewandert ist, hat weiterhin ein
+ * Rechteck, und das liegt dann rechnerisch ueber der Ueberschrift des Panels
+ * darunter, obwohl der Leser sie gar nicht sieht.
+ *
+ * **(a) Ueberlagerung.** Zwei Kandidaten derselben EBENE, von denen keiner den
+ * anderen enthaelt, duerfen sich mit ihren SICHTBAREN Rechtecken nicht
+ * schneiden. Die Ebene eines Elements ist sein naechster Vorfahre (es selbst
+ * eingeschlossen), der absolut, fest oder klebend positioniert ist; hat er
+ * keinen, ist die Ebene das Dokument. Das ist die Regel und nicht eine Liste
+ * von Ausnahmen, und sie trifft genau den Fehler, um den es geht: ein Overlay
+ * DARF ueber dem Text liegen, den es verdeckt, das ist sein Zweck. Zwei
+ * Beschriftungen IM Overlay duerfen es nicht. Welche Ebenen ein Halt hatte,
+ * steht im Ergebnis, damit die Ausnahme nachlesbar ist statt behauptet.
+ *
+ * **(b) Beschneidung.** Ein sichtbarer Kandidat darf nicht aus einem Kasten
+ * ragen, der ihn abschneidet und den man nicht aufscrollen kann. Gesucht wird
+ * der naechste Vorfahre mit `overflow: hidden` oder `clip` auf der jeweiligen
+ * Achse; ein `auto` oder `scroll` zaehlt nicht, denn was dort heraushaengt, ist
+ * erreichbar, und Erreichbarkeit ist genau der Unterschied zwischen "steht
+ * weiter unten" und "ist weg".
+ *
+ * Zwei Schwellen gehoeren dazu, und sie sind verschieden, weil die beiden
+ * Achsen verschieden sind. SENKRECHT ist der Kasten einer Textzeile fast immer
+ * ein paar Pixel hoeher als die Schrift darin (halbe Zeilendurchschuss ueber
+ * und unter den Buchstaben); ein Ueberstand von vier Pixeln schneidet dort
+ * nichts ab, was ein Leser sehen wuerde. Gemeldet wird deshalb erst, was mehr
+ * als ein gutes Drittel der Elementhoehe verdeckt. WAAGERECHT gibt es diesen
+ * Puffer nicht: was rechts abgeschnitten wird, sind Buchstaben. Dort zaehlt
+ * schon ein Ueberstand von zwei Pixeln, es sei denn, der Kasten sagt mit
+ * `text-overflow: ellipsis` selbst, dass er kuerzt: drei Punkte sind eine
+ * Ansage an den Leser und kein verschwundener Text.
+ *
+ * **(c) Eine Zeile, die an einer Bildlaufkante halb dasteht.** Ein Kasten, der
+ * scrollt, schneidet nichts weg: was heraushaengt, ist erreichbar, und deshalb
+ * meldet (b) ihn nicht. Das stimmt fuer den Explorer, in dem viele Dateien
+ * scrollen duerfen, und es war fuer die Legende der Galaxie zu nachsichtig
+ * (Bernhards Befund an den Beweisbildern von W9, 2026-08-29): dort stand ueber
+ * der ersten Zeile ein Rest wie "not more importance:" und unten endete ein
+ * Satz mitten im Wort. Die Zahlen waren gruen, die Bilder zeigten einen
+ * Darstellungsfehler.
+ *
+ * Gefragt wird darum am RUHEZUSTAND und an der ZEILE, und beide Einschraenkungen
+ * sind der Grund, dass die Regel eng bleibt:
+ *
+ *  - **Ruhezustand.** Nur ein Kasten, der noch am Anfang steht
+ *    (`scrollTop`/`scrollLeft` bei null), wird gefragt. Die Regel stellt die
+ *    Frage, die ein Leser beim OEFFNEN stellt: "ist das alles?". Wer selbst
+ *    gescrollt hat, hat die Antwort schon; und ein Kasten, den die Messung
+ *    unter (c) selbst ans Ende gefahren hat, zeigt einen Bildschirm, den dieses
+ *    Produkt nie ausliefert.
+ *  - **Zeile.** Gemeldet wird nicht, dass Inhalt ausserhalb steht (das ist der
+ *    Sinn eines Bildlaufs), sondern dass die Kante MITTEN DURCH eine Textzeile
+ *    geht: ein Teil der Zeile ist zu sehen, der andere nicht. Gemessen an den
+ *    Zeilenrechtecken des Textes selbst (`Range.getClientRects`) und nicht am
+ *    Rechteck des Absatzes, denn ein fuenfzeiliger Absatz, dem die halbe letzte
+ *    Zeile fehlt, ist an seinem Gesamtrechteck fast vollstaendig.
+ *
+ * Steht die Kante mitten in einer Zeile, dann muss der Kasten das SAGEN. Als

+/**
+ * **(e) Die Tooltips, und warum sie eine eigene Frage brauchen.**
+ *
+ * Bis W8b erklaerte sich diese Oberflaeche mit dem `title`-Attribut, 78 Mal.
+ * Der Browser zeichnet daraus einen Kasten AUSSERHALB des Dokuments, unter dem
+ * Mauszeiger und ohne Rechteck. Er hat damit keine der Eigenschaften, an denen
+ * (a) bis (d) messen: kein `getBoundingClientRect`, keine Ebene, kein
+ * Vorfahre. Es gab also 78 Flaechen, die sich ueber beliebigen Inhalt legen
+ * konnten, und null Messung darauf. Der Nutzer hat am 2026-08-29 fotografiert,
+ * was daraus folgt: der Tooltip der Kopfzeile lag ueber dem Detail-Regler und
+ * ueber den Chips Logic, Calls und Data.
+ *
+ * Seit W8b zeichnet diese Oberflaeche ihre Tooltips selbst (src/ui/tooltip/).
+ * Sie liegen im Dokument, also sieht (a) sie grundsaetzlich; nur greift die
+ * Ebenen-Regel bei ihnen absichtlich nicht, denn ein Tooltip ist fest
+ * positioniert und damit seine EIGENE Ebene. Das ist richtig so: ein Tooltip
+ * DARF ueber Fliesstext liegen, das ist seine Bauart. Was er nicht darf, ist
+ * das hier, und es ist eine engere Frage als die von (a):
+ *
+ *   Ein offener Tooltip darf nichts verdecken, was der Leser gerade BRAUCHT.
+ *
+ * Gebraucht heisst geschuetzt, und geschuetzt ist genau dreierlei: der
+ * Ausloeser selbst (ein Kasten, der den Knopf verdeckt, den man beruehrt, nimmt
+ * dem Zeiger sein Ziel), Regler und Eingabefelder, und die Flaechen, die die
+ * Oberflaeche mit `data-hint-keep` als Beschriftung ihrer Sektion ausweist.
+ * Dieselbe Liste, nach der die Oberflaeche selbst platziert (siehe
+ * src/ui/tooltip/tooltip-model.ts): zwei Formulierungen derselben Regel waeren
+ * zwei Regeln, und der Beweislauf soll die Zusicherung pruefen und nicht eine
+ * zweite daneben aufstellen.
+ *
+ * Der Lauf oeffnet dafuer JEDEN Tooltip einzeln und misst; die Zahl der so
+ * gemessenen steht als `domTooltipsMeasured` im Artefakt. Ein Lauf, der einmal
+ * hinsieht und "keine Ueberlagerung" meldet, haette ueber die 77 anderen
+ * nichts gesagt.

+/**
+ * Ein Stichprobenzaehler ueber den eigenen Prozessbaum: was hat gerade eine
+ * Gegenstelle offen, und liegt die auf Loopback?
+ *
+ * ## Warum ein Beweislauf das selbst misst, obwohl das Gate es auch tut
+ *
+ * tools/net-deny-gate.mjs beobachtet das Kommando VON AUSSEN und schreibt sein
+ * Ergebnis erst, wenn das Kommando fertig ist. Der Lauf selbst kann diese Zahl
+ * also nicht in sein eigenes Artefakt schreiben; er wuerde eine Datei lesen, die
+ * es zu seiner Laufzeit noch nicht gibt. Der Abnahmetest verlangt die Zahl aber
+ * in airgap.json, und eine abgeschriebene Zahl waere keine zweite Beobachtung,
+ * sondern dieselbe an einem zweiten Ort.
+ *
+ * Also misst der Lauf selbst, mit denselben Regeln: derselbe `classifyLine` und
+ * derselbe `isLoopbackHost` aus dem Gate, importiert und nicht nachgebaut. Nur
+ * die zwanzig Zeilen um `pgrep` und `lsof` herum stehen hier noch einmal. Das
+ * Gate umzubauen, damit es diese zwanzig Zeilen hergibt, waere eine Aenderung an
+ * dem Werkzeug, das jeden bisherigen Beweis dieses Projekts getragen hat, und
+ * zwar aus Bequemlichkeit eines neuen Laufs. Der Preis dafuer ist hoeher als
+ * zwanzig Zeilen.
+ *
+ * Die Grenze der Aussage ist dieselbe wie beim Gate und wird genauso genannt:
+ * eine Verbindung, die zwischen zwei Abtastungen aufgebaut, benutzt und
+ * geschlossen wird, kann durchrutschen. Deshalb steht die Zahl der Stichproben
+ * im Ergebnis. Ohne sie waere eine Null nicht lesbar.

+ * Der Versprechen-Scan: sucht im Produktpfad nach Saetzen, die etwas fuer
+ * spaeter zusagen, und nach Flaechen, die sich anklicken lassen und nichts tun.
+ *
+ *   node tools/promise-scan.mjs [--out verification/w7/promises.json]
+ *
+ * Nutzerauftrag vom 2026-08-29: "entferne alles, was Dinge verspricht, die wir
+ * nicht koennen". Der Auftrag ist mit vier Fundstellen erledigt worden (die vier
+ * Menuepunkte ohne Panel, die drei Twin-Saetze); dieses Werkzeug ist die Sperre
+ * dagegen, dass die fuenfte unbemerkt entsteht. Es laeuft als `npm run
+ * check:promises` und schreibt sein Ergebnis nach verification/w7/promises.json.
+ *
+ * ## Zwei Fragen, und warum es zwei sein muessen
+ *
+ * **(1) Sagt ein Satz etwas zu?** Ein Versprechen ist ein Satz, der eine
+ * Zukunft behauptet, ueber die dieses Produkt nicht verfuegt ("arrives later",
+ * "when X lands", "not wired"). Er ist an einem gruenen Testlauf nicht zu
+ * sehen, denn er ist syntaktisch tadellos.
+ *
+ * **(2) Schweigt eine Flaeche?** Ein Knopf ohne Handler ist dasselbe
+ * Versprechen ohne Worte. Er ist noch schlechter zu finden, weil er gar keinen
+ * Text hat, an dem man ihn suchen koennte. Gefragt wird deshalb der Syntaxbaum:
+ * jedes `button` und jedes Element mit `role="button"` muss einen Griff tragen,
+ * der auf eine Bedienung antwortet.
+ *
+ * ## Wo die Muster gelten, und warum nicht ueberall dasselbe
+ *
+ * Zwei Reichweiten, und der Unterschied ist kein Kompromiss, sondern die
+ * Aussage:
+ *
+ *  - `text`: die harten Muster gelten im GANZEN Quelltext, Kommentare
+ *    eingeschlossen. "not wired", "coming soon", "arrives later", "when X
+ *    lands", "TODO", "FIXME" und "demnaechst" sind auch in einer Begruendung
+ *    keine Begruendung, sondern eine Schuld, die niemand aufgeschrieben hat.
+ *  - `visible`: die weichen Muster gelten nur in dem, was auf dem Bildschirm
+ *    landet (String-Literale und JSX-Text, erkannt vom TypeScript-Parser).
+ *    "noch nicht" ist in einem deutschen Kommentar ueber einen Zustand
+ *    ("leer, solange noch nicht gelesen") eine Auskunft ueber die Laufzeit; im
+ *    Bildschirmtext einer englischsprachigen Oberflaeche waere es beides
+ *    zugleich falsch.
+ *
+ * `TODO` und `FIXME` werden in Grossbuchstaben gesucht. Das ist die Form, in
+ * der sie als Marke gemeint sind; ein `'todo'` in einer Stoppwortliste (so eins
+ * steht in src/compiler/question-classifier.ts) ist ein Datenwert und keine
+ * offene Aufgabe.
+ *
+ * ## Was NICHT gescannt wird
+ *
+ * Tests. Sie beschreiben, was nicht passieren darf, und muessen die verbotenen
+ * Formulierungen dafuer aussprechen duerfen. Ein Scan, der ihnen das verbietet,
+ * verbietet die Beschreibung des Verbots.

+/*
+ * Die Demo-Aufzeichnung: ein festes Drehbuch, einmal durchgefahren und gefilmt.
+ *
+ *   node tools/record-demo.mjs        (npm run demo:record)
+ *
+ * Das Ergebnis ist kein Beweis, sondern eine Vorfuehrung. Alle Beweise stehen
+ * schon: tools/smoke-w6-full.mjs faehrt dieselbe Oberflaeche und stellt an jedem
+ * Halt die harten Fragen (Netzstille, Ueberlagerung, Beschneidung, Budgets).
+ * Dieser Lauf hat eine andere Aufgabe: Martin soll das Produkt SEHEN, ohne es
+ * zu installieren. Darum ist hier alles auf Zusehbarkeit ausgelegt und nichts
+ * auf Messung.
+ *
+ * Ablauf:
+ *   1. `npm run build`
+ *   2. isoliertes HOME, eigenes Rendezvous-Verzeichnis, eigene Fixture-Kopie
+ *   3. zwei Projekte indizieren: die Fixture (nur gelesen) und eine KOPIE mit
+ *      eigenem git-Repository und einer echten Aenderung fuer den Blast-Radius
+ *   4. die Aufzeichnung ingestieren, BEVOR die Kamera laeuft
+ *   5. C-Server und dist/ auf Ports ab 4350, Sidecar auf 4141 warmlaufen lassen
+ *   6. Chromium mit Videoaufnahme, das Drehbuch Halt fuer Halt
+ *   7. abraeumen, Restprozesse zaehlen, Video und Drehbuch schreiben
+ *
+ * ## Fuenf Entscheidungen, die man sonst raten muesste
+ *
+ * **Der Sidecar startet VOR der Kamera.** llama-server laedt sein Modell in
+ * zweistelligen Sekunden, und diese Zeit gehoert in keinen Film. Im Video
+ * passiert nur das, was die Oberflaeche tut: der Schalter geht an, das Panel
+ * meldet `ready`, die Frage wird beantwortet. Der Prozessstart davor ist keine
+ * Produkteigenschaft, sondern eine Vorbedingung, und llm/start.sh sagt selbst,
+ * dass er von Hand oder aus einem Lauf kommt (llm/start.sh, Kopf).
+ *
+ * **Die Zeitmarken zaehlen ab dem ersten Bild und nicht ab dem Prozessstart.**
+ * demo.json ist damit ein Inhaltsverzeichnis in das Video: wer `atMs` in den
+ * Abspielort umrechnet, landet an genau dem Halt. Eine Marke ab Prozessstart
+ * waere um den Bau, das Indizieren und das Modellladen verschoben und damit
+ * unbrauchbar.
+ *
+ * **Jeder Halt haelt sichtbar an.** Ein Beweislauf darf so schnell klicken, wie
+ * die Anwendung antwortet; ein Film nicht. Die Pausen stehen als Konstanten
+ * beieinander (BEAT und die drei laengeren Fassungen) und nicht verstreut im
+ * Drehbuch, damit das Tempo an einer Stelle einstellbar bleibt.
+ *
+ * **Der Twin haengt am Caret und nicht an der Suche.** Das Drehbuch oeffnet
+ * die Route-Datei im Baum und klickt in die Zeile mit dem Aufruf, so wie ein
+ * Leser es taete; erst danach kommt die Suche, und zwar auf ein ANDERES Symbol.
+ * Damit ist die Kamerafahrt der Galaxy echt: sie faehrt von registerUserRoutes
+ * zu createUser. Haette der Twin schon vorher auf createUser gestanden, waere
+ * "flyTo" ein Wort ohne Bild.
+ *
+ * **Die Aenderungsansicht bekommt ihr eigenes Projekt.** Ein Blast-Radius ohne
+ * Aenderung ist leer; die Aenderung gehoert aber nicht in fixtures/, das
+ * byte-identisch bleibt. Also liegt eine Kopie mit eigenem git-Repository in
+ * einem mkdtemp-Verzeichnis, wird als zweites Projekt indiziert und
+ * verschwindet am Ende. Im Film ist der Wechsel als Neuladen zu sehen, und das
+ * ist ehrlicher als eine Aenderung, die aus dem Nichts kommt.

+// W0-Spike-Orchestrator. WEGWERF-BEWEISCODE, NICHT DIE PRODUKTARCHITEKTUR.
+//
+// Was hier bewiesen wird: der gebaute C-Server aus PR 1860 liefert echten
+// Quelltext über /rpc get_code_snippet, und Monaco rendert ihn read-only mit
+// genau einer Decoration an der Call-Site.
+//
+// Der Mini-Static-Server mit /rpc-Proxy weiter unten existiert nur, weil der
+// C-Server /rpc und /api gegen fremde Origins mit 403 sperrt (Host-Header muss
+// exakt 127.0.0.1:<port> oder localhost:<port> sein). Eine Spike-Seite auf
+// einem anderen Port kann /rpc daher nicht direkt fetchen. Die Produktlösung
+// ist, dass der C-Server das Frontend selbst ausliefert; dieser Proxy ist
+// ausdrücklich nur Gerüst für den Beweis und fliegt danach raus.
+//
+// Ablauf:
+//   1. Binary prüfen
+//   2. isoliertes HOME anlegen (persistierte Settings dürfen nie ins echte HOME)
+//   3. fixtures/atlas-sample indexieren (single-shot CLI)
+//   4. C-Server auf freiem Port P >= 4210 starten (MCP-initialize auf stdin,
+//      stdin bleibt offen)
+//   5. qualified_name von createUser über /rpc search_graph ermitteln
+//   6. Static+Proxy-Server auf P2 starten
+//   7. Playwright chromium headless auf die Spike-Seite, window.__spike lesen,
+//      Screenshot schreiben
+//   8. beide Prozesse beenden und Restprozesse auf P und P2 zählen
+//   9. verification/w0/spike.json schreiben

+/*
+ * W10-Smoke: das Modell gehoert dem Leser, und alles, was Rechenzeit kostet,
+ * steht an einem Ort und nennt seinen GEMESSENEN Effekt.
+ *
+ * Martin am 2026-08-29: "Fuer mich waere wichtig, dass das Modell das Binary
+ * nicht gross verseucht. Man bietet in der UI das Feature so an, dass man sich
+ * von zum Beispiel Hugging Face selber ein Modell aussuchen kann." Und der
+ * Nutzer am selben Tag: "2D/3D oder sowas sollte immer zentral in einem
+ * Settings-Menue drin sein, nicht alles auf einer Oberflaeche, wegen
+ * Rechenleistung falls jemand keine so starke Maschine hat."
+ *
+ * Dieser Lauf prueft beide Zusicherungen an der laufenden Oberflaeche, gegen
+ * einen echten llama-server, und er tut es, ohne den Arbeitsplatz des Nutzers
+ * anzufassen.
+ *
+ * ## Die drei Kunstgriffe dieses Laufs
+ *
+ * 1. **Ein eigener Router-Sidecar mit ZWEI Modellen, ohne ein Byte zu laden.**
+ *    Umschalten laesst sich nur messen, wenn es zwei Modelle gibt. Zwei Dateien
+ *    zu kopieren waere 1,4 GB und eine Minute; zwei nachzuladen waere ein
+ *    Netzzugriff, den dieser Lauf nicht haben darf. Also stehen sie als HARTE
+ *    LINKS in einem eigenen Cache-Verzeichnis: derselbe Inhalt, dieselbe
+ *    Inode, kein zusaetzlicher Platz, sofort da. Ein harter Link loescht beim
+ *    Aufraeumen nichts: die Dateien in models/ tragen danach nur wieder einen
+ *    Link weniger. Dass alle sechs am Ende noch da sind, wird gemessen und
+ *    steht im Artefakt (`modelsAfterRun`).
+ *
+ * 2. **Die Umleitung an der Naht, an der die Anwendung selbst fragt.** Das
+ *    Produkt redet mit 127.0.0.1:4141, und dieser Port gehoert dem Nutzer:
+ *    dort laeuft sein eigener Sidecar, waehrend dieser Lauf laeuft. Wie in
+ *    smoke-w7c ersetzt ein `addInitScript` das `globalThis.fetch` der Seite und
+ *    schickt alles, was mit dem Produktursprung beginnt, an den Port dieses
+ *    Laufs. Der Zustandsautomat, die Probe, das Panel und der Chat laufen
+ *    unveraendert. Dass an 4141 wirklich kein Byte ging, steht als
+ *    `productPortRequests` (muss 0 sein) im Artefakt; der Route-Handler bricht
+ *    eine Anfrage dorthin ausdruecklich ab, statt sie durchzulassen.
+ *
+ * 3. **Zwei Sidecars nacheinander, nicht nebeneinander.** AC2 hat zwei
+ *    Haelften: mit Router waehlt ein Klick das Modell, ohne Router sagt das
+ *    Panel genau das und bietet keine wirkungslose Auswahl an. Der zweite
+ *    Sidecar startet erst, wenn der erste samt seiner Kindprozesse beendet ist.
+ *    Der Router startet je Modell eine eigene Instanz auf einem ephemeren Port;
+ *    diese Ports werden mitgeschrieben und beim Abbau mitgezaehlt.
+ *
+ * ## Was hier eine Messung ist und was nicht
+ *
+ * Jede Zahl in verification/w10/models.json hat in `extras` das, woraus sie
+ * entstanden ist: die selbst abgefragten Props neben den Werten im Panel, die
+ * zwei Modellnamen aus den aufgezeichneten Antwortkoerpern, je Einstellung die
+ * Bildrate vorher und nachher samt Urteil, die vier Fundstellen des
+ * Ehrlichkeitssatzes, die drei Teile von `noWeightsInRepo`, die Zaehlung der
+ * Fortschrittselemente und die Aufraeumzahlen. Wo etwas nicht ehrlich als
+ * `true` zu messen war, steht `false` und der Grund; ein geschoentes `true`
+ * waere kein Ergebnis.
+ *
+ * ## Die Grenze, die dieser Lauf nicht ueberschreitet
+ *
+ * Gemessen wird in headless Chromium mit SwiftShader, also in Software-GL. Die
+ * ABSOLUTEN Bildraten sind darum nicht die eines Lesers mit Metal auf demselben
+ * Rechner. Was dieser Lauf beweist, ist die Mechanik (jede Einstellung greift,
+ * jede nennt ihre zwei Zahlen, das Urteil kennt auch "kein messbarer
+ * Unterschied") und die Zahlen DIESER Umgebung. Der Satz steht noch einmal in
+ * `method` und in `extras.frameRateEnvironment`, damit niemand eine dieser
+ * Zahlen fuer die seines Rechners haelt.
+ *
+ * ## Ablauf
+ *
+ *   1. `npm run build`
+ *   2. isoliertes HOME, eigenes Rendezvous-Verzeichnis (CBM_RUNTIME_DIR)
+ *   3. fixtures/atlas-sample indizieren (die Fixture wird nur gelesen)
+ *   4. C-Server auf einem freien Port >= 4580, dist/ auf einem zweiten
+ *   5. eigenes Cache-Verzeichnis mit zwei harten Links, Router auf einem dritten
+ *   6. Chromium ohne Aussenwelt, mit Umleitung und Route-Sperre
+ *      a. AC5: das Panel bei AUSGESCHALTETEM Modell, zwei Poll-Intervalle lang
+ *      b. Modell an; das Panel auf zwei Wegen oeffnen
+ *      c. AC1/AC3: die vier Zahlen gegen die eigene Abfrage, die Cache-Liste,
+ *         die sechs Vorschlaege gegen verification/w5/eval.json, das freie Feld,
+ *         der Kopieren-Knopf gegen die Zwischenablage, der Ehrlichkeitssatz in
+ *         vier Teilen, die Zaehlung der Fortschrittselemente
+ *      d. AC2: umschalten, fragen, zurueckschalten, fragen; zwei Modellnamen
+ *         aus den aufgezeichneten Antworten; Reload; Statusleiste
+ *      e. AC9: acht Einstellungen, je Bildrate vorher und nachher; die flache
+ *         Ansicht an den Beschriftungen belegt; die Ansichtsschalter, die
+ *         bleiben, wo sie sind; Reload
+ *   7. AC4 am Startskript, ohne einen Prozess zu starten
+ *   8. AC8 an der Funktion selbst und an der Rechnung der Eval
+ *   9. AC2 zweite Haelfte: derselbe Weg gegen einen Sidecar OHNE Router
+ *  10. abraeumen, Restprozesse zaehlen, JSON und drei Bilder schreiben
+ *
+ * Das Ganze laeuft unter dem Netz-Deny-Gate (npm run smoke:w10).
+ *
+ * ## Ports
+ *
+ * Ab 4580. 4141 gehoert dem Modell-Sidecar des Nutzers, 4390 und 4391 seiner
+ * Vorschau; alle drei fasst dieser Lauf nicht an, weder startend noch beendend.
+ * 4210 bis 4560 sind an die Laeufe davor vergeben.

+/*
+ * W10b-Smoke: die Griffe erklaeren nichts mehr, die Ansichts-Knoepfe klappen,
+ * die Hierarchie waechst aus dem Fokus, und der Graph passt ins Bild.
+ *
+ * ## Warum dieser Lauf existiert
+ *
+ * Fuenf Nutzerbefunde vom 2026-08-29 Abend und 2026-08-30 Vormittag. Sie sind
+ * einzeln klein und haben dieselbe Wirkung: sie halten jemanden auf, der die
+ * Oberflaeche benutzen will.
+ *
+ *  1. "diese Meldung nicht anzeigen ... Bitte an allen Bordern die Meldung
+ *     entfernen." Der vierzeilige Kasten an den vier Zonengriffen.
+ *  2. "die beiden Buttons unten links sollten auch aufklappen und zuklappen
+ *     koennen." Der Ansichts-Schalter war ein reiner Umschalter.
+ *  3. "und hierarchies werden auch nicht angezeigt." Die Projektion hing am
+ *     Einstiegs-Spaziergang; ein Symbol im Fokus reichte nicht.
+ *  4. "mich nervt, dass die Galaxy manchmal einfach flach ist" und "auch soll
+ *     der Graph am besten standardmaessig immer ganz sichtbar sein."
+ *  5. Der Vorschau-Server kopiert `dist` beim Start und sieht spaetere Bauten
+ *     nie. Das ist kein Produktfehler, sondern ein Loch im Ablauf.
+ *
+ * ## Was hier gemessen wird und nicht behauptet
+ *
+ * Der Kern dieses Laufs ist Punkt 4, und er ist eine Aussage ueber ein BILD.
+ * Sie wird darum am Bild bewiesen und nicht an der Absicht: die Szene meldet
+ * ueber `globalThis.__atlasGalaxyFit`, wo JEDER ihrer Knoten in der
+ * Zeichenflaeche liegt (Projektion mit genau der Kamera, die gerade zeichnet;
+ * src/galaxy/GraphScene.tsx). Der Lauf liest daran zwei Zahlen: wie viele
+ * Knoten ausserhalb liegen (null) und wie viel Rand der aeusserste noch hat
+ * (mehr als null Pixel).
+ *
+ * Die zweite Haelfte von Punkt 4 ist die AUSRICHTUNG, und die wird
+ * UNABHAENGIG geprueft: dieser Lauf rechnet die Hauptachsen der geladenen
+ * Knotenpositionen selbst (Jacobi, `principalAxes` unten) und haelt die
+ * duennste Achse gegen die Blickrichtung, die die Kamera gemeldet hat. Die
+ * Rechnung der Oberflaeche und die Rechnung dieses Laufs teilen keine Zeile
+ * Code; stimmen sie ueberein, steht die Kamera wirklich senkrecht auf der
+ * groessten Flaeche.
+ *
+ * Gemessen wird ausserdem, dass die Messung ueberhaupt etwas sieht: bevor der
+ * Knopf "fit view" gedrueckt wird, verdreht der Lauf die Kamera mit Zug und
+ * Rad, bis Knoten aus dem Bild fallen, und schreibt die Zahl auf. Ein
+ * Nachweis "null Knoten ausserhalb" von einer Messung, die nie etwas anderes
+ * gemeldet hat, waere kein Nachweis.
+ *
+ * ## Zwei Groessen, und warum die zweite synthetisch ist
+ *
+ * Die Fixture dieses Projekts hat 76 Knoten. Der Nutzer indiziert daneben sein
+ * echtes Projekt: 5000 Knoten, 5209 Kanten, 17 Kantenarten. Die Einpassung muss
+ * bei beiden stimmen, also misst dieser Lauf beide. Die grosse Wolke kommt
+ * dabei ueber DIESELBE Route (`/api/layout`) in dieselbe Oberflaeche, ihr
+ * Inhalt ist aber erzeugt und nicht indiziert: sie traegt genau die Form der
+ * echten Antwort (Zahlen oben) und eine gedrehte, in den drei Richtungen
+ * verschieden weite Punktwolke. Das steht so im Artefakt, damit niemand die
+ * Zahl fuer eine Messung an echtem Code haelt.
+ *
+ * ## Ablauf
+ *
+ *   1. `npm run build`
+ *   2. isoliertes HOME, eigenes Rendezvous-Verzeichnis (CBM_RUNTIME_DIR)
+ *   3. fixtures/atlas-sample indizieren (die Fixture wird nur gelesen)
+ *   4. C-Server auf einem freien Port >= 4640, dist/ auf einem zweiten
+ *   5. Chromium ohne Aussenwelt, plus Route-Sperre

+/*
+ * W11a-Smoke: Agenten sind sichtbare Wesen im Code, und das Instrument sagt,
+ * was man sieht.
+ *
+ * Nutzerwunsch vom 2026-08-29, woertlich: "wie wuerdest du in dem Projekt
+ * einbauen, dass wir am Graphen unten rechts Agents sehen, wenn sie live
+ * arbeiten? Welche Farben haben sie, wie wissen wir welche Art von Arbeit ein
+ * Agent macht?"
+ *
+ * ## Die vier Kunstgriffe dieses Laufs
+ *
+ * 1. **Eine echte Bruecke, aber mit angehaltener Zeit.** Der Beweislauf startet
+ *    tools/agent-bridge.mjs im Wiedergabemodus gegen
+ *    fixtures/agent-events/w11a-replay.jsonl. Die Bruecke liest die Datei
+ *    einmal und schweigt danach, bis jemand `POST /replay/advance` ruft. Damit
+ *    faehrt derselbe Ablauf in jedem Lauf durch dieselben Zustaende, statt auf
+ *    eine Wanduhr zu warten: die Aufzeichnung dauert mit ihren echten
+ *    Zeitabstaenden acht Minuten, dieser Lauf braucht dafuer Sekunden, und
+ *    zwischen zwei Schritten steht das Bild still genug, um es zu vermessen.
+ *
+ * 2. **Drei Zustaende der Quelle, alle drei gemessen.** Aus (kein einziger
+ *    fetch, gezaehlt an `page.on('request')` UND an der Naht der Anwendung),
+ *    an ohne Bruecke (ein Port, auf dem mit Absicht niemand lauscht, damit die
+ *    ehrliche Meldung samt Startbefehl entsteht), an mit Bruecke.
+ *
+ * 3. **Die Zuordnung wird gegen die Layout-Antwort geprueft, nicht gegen die
+ *    Ansicht.** Welcher Knoten zu `src/services/userService.ts` Zeile 24 bis 30
+ *    gehoert, rechnet dieser Lauf selbst aus `/api/layout` aus: alle Knoten der
+ *    Datei, deren Bereich sich ueberschneidet, der engste davon. Die Ansicht
+ *    gegen ihre eigene Zahl zu pruefen waere keine Pruefung.
+ *
+ * 4. **Der Orbit wird als Bildserie belegt.** Acht Einzelbilder ueber eine
+ *    Umkreisung, der Winkel je Bild aus derselben Tabelle gelesen, die den
+ *    Koerper bewegt, und ein Kontaktabzug daraus (ffmpeg). Eine Bildserie, auf
+ *    der sich nichts aendert, ist damit ein Befund und kein Erfolg.
+ *
+ * ## Was hier eine Messung ist und was nicht
+ *
+ * `nodeColorsUnchanged` ist die heikelste Zahl dieses Laufs, und sie steht
+ * darum aus DREI Teilen zusammen, die alle im Artefakt einzeln nachzulesen
+ * sind: die Farbwerte der Legende sind mit und ohne Ebene dieselben (exakt,
+ * Zeichenkettenvergleich), die Menge des warmen Knotenlichts im Bild ist
+ * dieselbe (Pixelhistogramm der Knotenfamilie, Abweichung unter einem halben
+ * Prozent), und die Ebene beruehrt ueberhaupt nur einen kleinen Teil der
+ * Flaeche (geaenderte Pixel unter vier Prozent). Ein einzelnes `true` ohne
+ * diese drei Zahlen waere eine Behauptung.
+ *
+ * ## Ports
+ *
+ * Ab 4620. 4141 gehoert dem Modell-Sidecar des Nutzers, 4142 ist fuer SEINE
+ * Bruecke vorgesehen, 4390 und 4391 seiner Vorschau; alle vier fasst dieser
+ * Lauf nicht an, weder startend noch beendend. 4210 bis 4600 sind an die Laeufe
+ * davor vergeben.
+ *
+ * Das Ganze laeuft unter dem Netz-Deny-Gate (npm run smoke:w11a).

+/*
+ * W11b-Smoke: ein Agent teleportiert nicht.
+ *
+ * Er fliegt in etwa einer halben Sekunde auf einer gebogenen Bahn zum naechsten
+ * Symbol, mit kurzem Kometenschweif, und hinter ihm bleibt die Spur der zuletzt
+ * besuchten Knoten stehen. Er atmet im Takt seiner Ereignisse und haelt an,
+ * wenn sie aufhoeren. Dazu drei filmische Zustaende mit je einer Regel
+ * dahinter, der Zeitstrahl unten und der Vollbildmodus.
+ *
+ * ## Die fuenf Kunstgriffe dieses Laufs
+ *
+ * 1. **Vier Akte, vier Bruecken.** Die Wiedergabe schiebt die Zeitstempel der
+ *    Aufzeichnung auf die Gegenwart, und zwar EINMAL, beim Start der Bruecke.
+ *    Ein Lauf, der danach zwei Minuten misst, misst am Ende an Akteuren, deren
+ *    letztes Ereignis zwei Minuten zurueckliegt: die sind dann ruhig, und das
+ *    ist richtig so. Was gemessen werden soll, ist aber die Bewegung. Jeder Akt
+ *    bekommt darum seine eigene Bruecke auf einem eigenen Port und laedt die
+ *    Seite neu; damit steht jede Messung an frischen Zeiten, statt an Zeiten,
+ *    die der Lauf selbst hat altern lassen.
+ *
+ * 2. **Die Bahn wird nicht abgefragt, sie wird aufgezeichnet.** Der Koerper
+ *    schreibt waehrend eines Fluges jeden Punkt, den er zeichnet, in eine
+ *    Tabelle (src/galaxy/AgentLayer.tsx, `agentMotion`). Dieser Lauf liest sie
+ *    NACH dem Flug und rechnet die Kruemmung selbst aus den Punkten nach. Eine
+ *    halbe Sekunde lang alle 25 ms nachzufragen hiesse, die Messung an der
+ *    Antwortzeit einer Fernsteuerung aufzuhaengen.
+ *
+ * 3. **Die Radien werden unabhaengig nachgerechnet.** Welchen Bahnradius drei
+ *    Akteure am selben Symbol bekommen, rechnet dieser Lauf aus der Regel
+ *    (Radius der Art, dann Kennung, dann Mindestabstand) noch einmal aus und
+ *    haelt das Ergebnis gegen die Ansicht. Die Ansicht gegen ihre eigene Zahl
+ *    zu pruefen waere keine Pruefung.
+ *
+ * 4. **Der Puls wird an ZWEI Instrumenten gemessen.** Die Groesse des Koerpers
+ *    kommt aus dem DOM (`getBoundingClientRect`), das Licht eines Knotens aus
+ *    den Pixeln eines Bildausschnitts. Beide ueber dieselben Bilder. Der Satz,
+ *    der dabei geprueft wird, ist "ein Knoten leuchtet gleichmaessig, ein Agent
+ *    atmet", und er ist erst dann gemessen, wenn beide Zahlen daneben stehen.
+ *
+ * 5. **Die Bewegung wird als Bildserie belegt.** Sechzehn Einzelbilder in
+ *    gleichen Abstaenden der gesteuerten Zeit (ein Bild je Wiedergabeschritt),
+ *    ein Kontaktabzug daraus, dazu eine Aufnahme fuer den Menschen. Zwei
+ *    aufeinanderfolgende Bilder, zwischen denen sich nichts aendert, sind ein
+ *    Befund und kein Erfolg; dieser Lauf vergleicht sie Pixel fuer Pixel.
+ *
+ * ## Ports
+ *
+ * Ab 4520. Dem Nutzer gehoeren 4141 (Modell-Sidecar), 4142 (seine Bruecke),
+ * 4390/4391 und 4392/4393 (zwei Vorschauen). Keinen davon fasst dieser Lauf an,
+ * weder startend noch beendend.
+ *
+ * Das Ganze laeuft unter dem Netz-Deny-Gate (npm run smoke:w11b).

+/*
+ * W12-Smoke: jeder Knopf wird angefasst, keiner darf sich davor druecken.
+ *
+ * ## Was dieser Lauf anders macht als die zwoelf davor
+ *
+ * Die bestehenden Beweislaeufe klappern ein Drehbuch ab: sie wissen, welchen
+ * Knopf sie druecken, und pruefen, ob dahinter das Richtige steht. Keiner von
+ * ihnen kann sagen, ob etwas VERGESSEN wurde, und genau daher kamen alle
+ * Befunde der Sorte "der Knopf macht nichts": vom Nutzer, nicht aus einem Lauf.
+ *
+ * Dieser Lauf hat kein Drehbuch. Er stellt Zustaende her, SUCHT SICH SELBST
+ * ZUSAMMEN, was darin bedienbar ist, und fasst jedes gefundene Element an,
+ * einmal mit der Maus und einmal mit der Tastatur. Was er nicht bedienen kann,
+ * meldet er; was nichts tut, ist ein Befund.
+ *
+ * ## Die fuenf Kunstgriffe
+ *
+ * 1. **Die Liste der Bedienelemente steht nicht in dieser Datei.** Gesammelt
+ *    wird ueber die Gattung (`button`, `[role="button"]`, `a[href]`, `input`,
+ *    `select`, `[tabindex]:not([tabindex="-1"])`, `[role="separator"]`,
+ *    `[role="tab"]`), in jedem Zustand neu. Eine Liste im Quelltext waere eine
+ *    Erwartung, die gruen bleibt, wenn das Produkt einen Knopf dazubekommt.
+ *
+ * 2. **Was sich von selbst bewegt, wird vorher gemessen.** Eine Bildrate, ein
+ *    Zaehler, eine Uhr: es gibt Werte, die sich ohne Zutun aendern, und ein
+ *    Lauf, der sie mitzaehlt, findet ueberall Wirkung. Vor dem ersten Klick
+ *    wird darum in JEDEM Zustand zweimal dasselbe gemessen, ohne etwas zu tun;
+ *    was sich dabei unterscheidet, ist fluechtig und faellt aus dem Vergleich.
+ *    Welche Schluessel das waren, steht im Artefakt.
+ *
+ * 3. **Ein Element, das schon an ist, bekommt eine zweite Gelegenheit.** Ein
+ *    Klick auf den bereits gewaehlten Reiter aendert nichts, und das ist kein
+ *    Fehler des Reiters. Zeigt ein Element seinen Zustand (`aria-pressed`,
+ *    `aria-selected`, `data-on`, `data-active`) und steht es auf "an", geht der
+ *    Lauf ueber einen Nachbarn derselben Gruppe weg und kommt zurueck. Erst
+ *    wenn auch das nichts bewirkt, ist es ein Befund.
+ *
+ * 4. **Die Tastatur nimmt den Weg, den die Rolle vorsieht.** Ein Knopf hoert
+ *    auf die Leertaste, ein Trenner (`role="separator"`) auf die Pfeiltasten,
+ *    ein Regler auch, eine Zeile im Explorer ueber den Cursor der Liste, eine
+ *    Trefferzeile ueber die Kommandozeile. "Enter oder Leertaste" auf einem
+ *    Trenner waere die Pruefung einer Zusicherung, die niemand gegeben hat.
+ *    Welche Taste gewirkt hat, steht je Element im Artefakt.
+ *
+ * 5. **Ein Filter muss WEGNEHMEN.** Fuer jeden Schalter, der etwas ein- oder
+ *    ausblendet, genuegt nicht, dass sich irgendetwas aendert: gezaehlt wird,
+ *    was vorher und nachher dasteht (Zeilen, Kanten, Koerper, Namen), und
+ *    Abschalten muss die Zahl senken, Einschalten sie zurueckbringen. Bleibt
+ *    sie bei null, weil es nichts zu zeigen gibt, muss die Flaeche das sagen.
+ *
+ * ## Die Schleife
+ *
+ * Ein Aufruf ist eine ETAPPE und misst so viel, wie in seine Zeitgrenze passt;
+ * er fuehrt seine Messung mit der vorhandenen verification/w12/buttons.json
+ * zusammen. Eine RUNDE ist etwas anderes: ein vollstaendiger Durchgang durch
+ * alle Zustaende und alle Filter, aus beliebig vielen Etappen zusammengesetzt.
+ * Ein Zyklus ist fertig, wenn zwei Durchgaenge hintereinander null Befunde
+ * melden; `newFindings` ist darum die Zahl der Befunde DIESES Durchgangs und
+ * nicht die Zahl der neu hinzugekommenen. Der Unterschied ist der ganze Sinn:
+ * ein Durchgang, der denselben Befund noch einmal findet, hat nichts geloest.
+ * Die Regeln der Etappen stehen weiter unten, bei {@link STAGE_MS}.
+ *
+ * ## Was dieser Lauf NICHT misst
+ *
+ * Ob die Wirkung eines Knopfes die RICHTIGE ist. Dass der Reiter "flow" den
+ * Flow zeigt und nicht den Chat, prueft smoke-w8b; dass die Fuenf-Stufen des
+ * Reglers verschiedene Texte ergeben, prueft smoke-w13. Dieser Lauf prueft
+ * Vollstaendigkeit: dass jedes Bedienelement erreichbar ist, dass es antwortet,
+ * und dass ein Filter filtert. Er ersetzt keinen der anderen.
+ *
+ * ## Ablauf
+ *
+ *   1. `npm run build`
+ *   2. isoliertes HOME, eigenes Rendezvous-Verzeichnis (CBM_RUNTIME_DIR)
+ *   3. fixtures/atlas-sample indizieren (die Fixture wird nur gelesen)
+ *   4. C-Server auf einem freien Port >= 4580, dist/ auf einem zweiten,
+ *      die Agenten-Bruecke im Wiedergabemodus auf einem dritten
+ *   5. Chromium ohne Aussenwelt, plus Route-Sperre und Sidecar-Stub
+ *      a. je Zustand: herstellen, fotografieren, Lesbarkeit messen,
+ *         Bedienelemente sammeln, Tab-Reihenfolge abgehen
+ *      b. je neues Element: Maus, wiederherstellen, Tastatur, wiederherstellen
+ *      c. die Filter, jeder mit seiner Zahl vorher und nachher
+ *   6. abraeumen, Restprozesse mehrfach zaehlen, JSON, Bilder, buttons.md
+ *
+ * Das Ganze laeuft unter dem Netz-Deny-Gate (npm run smoke:w12).
+ *
+ * ## Ports
+ *
+ * Ab 4580. 4141 gehoert dem Modell-Sidecar des Nutzers, 4142 seiner
+ * Agenten-Bruecke, 4390/4391 und 4392/4393 seinen zwei Vorschauen; alles
+ * darunter gehoert den Laeufen davor. Dieser Lauf fasst keinen davon an: der
+ * Sidecar wird IM BROWSER beantwortet (Route-Griff, keine Verbindung), die
+ * Bruecke bekommt einen eigenen Port.

+// ------------------------------------------------------------- Die Etappen ---
+
+/**
+ * Warum dieser Lauf in Etappen zerfaellt.
+ *
+ * Der erste Versuch wollte alles in einem Browser und einer Runde erledigen:
+ * 22 Zustaende, ihre Bedienelemente und die Filter, am Stueck. Nach 59,9
+ * Minuten war der Browser weg ("Target page, context or browser has been
+ * closed"), die Runde hatte kein einziges Bedienelement angefasst, und
+ * buttons.json trug 21 Zustaende und null Elemente. Eine Stunde Arbeit ohne
+ * Ergebnis, weil alles an einem Faden hing.
+ *
+ * Daraus folgen vier Regeln:
+ *
+ * 1. Nach JEDEM Zustand und nach jedem angefassten Element wird buttons.json
+ *    fortgeschrieben. Was gemessen ist, bleibt gemessen, auch wenn der naechste
+ *    Zustand scheitert.
+ * 2. Ein Aufruf ist eine Etappe und hat seine eigene Zeitgrenze
+ *    (`W12_STAGE_MS`, acht Minuten). Reisst sie, ist das ein Befund DIESER
+ *    Etappe; der naechste Aufruf macht dort weiter, wo sie aufhoerte, und der
+ *    Befund verschwindet, wenn der Zustand fertig gemessen ist.
+ * 3. Ein Browser traegt hoechstens fuenf Einheiten (`W12_BROWSER_UNITS`).
+ *    Danach wird er geschlossen und neu geoeffnet, und die Wiederherstellung
+ *    navigiert in den naechsten Zustand zurueck. Stirbt er vorher, ist das ein
+ *    Befund MIT ZUSTANDSNAMEN und kein stiller Abbruch.
+ * 4. Die Elementphase kommt vor den Bildern. Was gemessen werden muss, wird
+ *    zuerst gemessen; das Bild ist der Beleg und nicht die Messung.
+ *
+ * Welche Zustaende eine Etappe faehrt, sagt `W12_STATES` (Namen mit Komma
+ * getrennt, `pending` fuer alles, was in diesem Durchgang noch fehlt, `none`
+ * fuer keinen); welche Filter, sagt `W12_FILTERS` nach denselben Regeln. Ohne
+ * beides laeuft die Etappe ueber alles, wie vorher auch.

+/*
+ * W13-Smoke: der Regler fragt nicht mehr wie viel, sondern fuer wen.
+ *
+ * ## Was dieser Lauf beantwortet, und warum keiner davor es konnte
+ *
+ * Nutzerbefund vom 2026-08-29, woertlich: "ich seh gar keine Aenderungen". Der
+ * Befund war weder bestaetigt noch widerlegt, weil die Probe, die ihn messen
+ * sollte, an den falschen Kennungen hing und vier Nullen meldete. Er wird hier
+ * nicht geglaubt und nicht wegerklaert, sondern gemessen, und zwar an der
+ * schaerfsten Stelle: bei AUSGESCHALTETEM Modell.
+ *
+ * Fuenf Stufen, ein Symbol, fuenf Messungen. Fuer jede Stufe die Zeichenzahl
+ * des gerenderten Koerpers, seine erste Zeile, die Zahl der Abschnitte und die
+ * Menge der Testmarken, die im DOM stehen. Daraus zwei Zahlen, die keine
+ * Behauptung sind: `allLevelsDiffer` (keine zwei Stufen ergeben denselben Text)
+ * und je Stufe ein `uniqueElement`, ausgerechnet als die Marke, die genau auf
+ * dieser einen Stufe vorkommt. Eine Anwendung, die ohne Modell vollstaendig
+ * sein soll, darf keinen Regler haben, der ohne Modell nichts tut.
+ *
+ * ## Die vier Kunstgriffe dieses Laufs
+ *
+ * 1. **Das eigene Element wird ausgerechnet, nicht aufgezaehlt.** Der Lauf
+ *    sammelt je Stufe alle `data-testid` des Twin-Koerpers und schneidet die
+ *    fuenf Mengen gegeneinander. Eine Liste im Quelltext dieses Laufs waere
+ *    eine Erwartung, die gruen bleibt, wenn das Produkt sie nicht mehr
+ *    erfuellt.
+ *
+ * 2. **Der Sidecar wird IM BROWSER beantwortet und nie angefasst.** Port 4141
+ *    gehoert dem Nutzer; dieser Lauf startet dort nichts, beendet dort nichts
+ *    und verbindet sich dorthin nicht. Jede Anfrage, die die Anwendung dorthin
+ *    richtet, faengt der Route-Griff von Playwright ab und beantwortet sie aus
+ *    einem Skript, bevor eine Verbindung entsteht. Was dabei angefragt wurde,
+ *    steht vollstaendig im Artefakt (`extras.sidecar.requests`).
+ *
+ * 3. **Der Waechter wird durch die echte Funktion gefuehrt.** Die sieben
+ *    gefaelschten Umformulierungen laufen durch `applyReaderRewrite`, an
+ *    derselben Stelle, an der der Knopf sie hindurchschickt
+ *    (`__atlasTwin.validateRewrite`). Ein Lauf, der die Regel nachbaut und
+ *    gegen den Nachbau prueft, prueft den Nachbau.
+ *
+ * 4. **Der leere Fall wird gesucht und nicht angenommen.** Fuer AC7 geht der
+ *    Lauf mehrere Symbole durch, bis er eins findet, dessen Senior-Stufe
+ *    keinen einzigen Fehlerpfad hat, und misst dort, ob die Flaeche trotzdem
+ *    etwas sagt. Welches Symbol es war, steht im Artefakt.
+ *
+ * ## Was hier NICHT gemessen wird, und das ist wichtig
+ *
+ * Die Schreibqualitaet eines echten Modells. Der Modellport des Nutzers ist
+ * tabu, und ein zweites llama-server auf einem eigenen Port waere in diesem
+ * Lauf kein Beweis ueber das Produkt, sondern ein zweiter Prozess mit eigener
+ * Ladezeit. Gemessen wird die LEITUNG und der WAECHTER: dass die Anwendung mit
+ * dem Modell an genau diese Saetze verschickt, dass eine treue Antwort
+ * angewendet und mit ihrem Herkunftsvermerk gezeichnet wird, und dass eine
+ * Antwort mit einem erfundenen Namen verworfen wird und der Leser den Grund
+ * liest. Was der Stub zurueckgibt, ist eine deterministische, faktentreue
+ * Umschreibung und keine Modellprosa; das steht auch im Artefakt.
+ *
+ * ## Ablauf
+ *
+ *   1. `npm run build`
+ *   2. isoliertes HOME, eigenes Rendezvous-Verzeichnis (CBM_RUNTIME_DIR)
+ *   3. fixtures/atlas-sample indizieren (die Fixture wird nur gelesen)
+ *   4. C-Server auf einem freien Port >= 4600, dist/ auf einem zweiten
+ *   5. Chromium ohne Aussenwelt, plus Route-Sperre und der Sidecar-Stub
+ *      a. createUser oeffnen, die fuenf Stufen durchfahren und vermessen
+ *      b. Reload und Symbolwechsel: haelt die Wahl?
+ *      c. der leere Fall auf der Senior-Stufe
+ *      d. der Waechter, sieben Faelschungen und eine treue Antwort
+ *      e. Modell an: anwenden, zeichnen, verwerfen, Grund lesen
+ *   6. abraeumen, Restprozesse mehrfach zaehlen, JSON und fuenf Bilder
+ *
+ * Das Ganze laeuft unter dem Netz-Deny-Gate (npm run smoke:w13).
+ *
+ * ## Ports
+ *
+ * Ab 4600. 4141 gehoert dem Modell-Sidecar des Nutzers, 4142 seiner
+ * Agenten-Bruecke, 4390/4391 und 4392/4393 seinen zwei Vorschauen; alles bis
+ * 4600 gehoert den Laeufen davor. Dieser Lauf fasst keinen davon an.

+ * W1b-Smoke: die portierte Provider-Schicht gegen den echten Server.
+ *
+ * Was hier bewiesen wird, ist genau das, was Unit-Tests nicht beweisen
+ * koennen: dass CbmRpcProvider, rpc-client, der Parser und der IR-Builder
+ * zusammen an einem laufenden cbm/build/c/codebase-memory-mcp dieselben
+ * Fakten herausholen, die das Fixture wirklich hergibt. Gemockt ist hier
+ * nichts. Der Provider bekommt einen base-Ursprung und Node-18-fetch, sonst
+ * ist es dieselbe Klasse, die spaeter im Browser laeuft.
+ *
+ * Ablauf:
+ *   1. Binary und Fixture pruefen
+ *   2. isoliertes HOME anlegen (persistierte Einstellungen nie ins echte HOME)
+ *   3. fixtures/atlas-sample ueber die CLI indizieren; ueber /rpc geht das
+ *      nicht, weil die Read-only-Allowlist index_repository nicht anbietet
+ *   4. Server auf freiem Port >= 4220 starten
+ *   5. src/** mit esbuild zu einem ESM-Bundle machen und importieren. Das ist
+ *      kein Umweg, sondern ein zweiter Beweis: was sich buendeln laesst, hat
+ *      keine Node-Abhaengigkeit mehr, und genau das ist die Bedingung dafuer,
+ *      dass diese Dateien im Browser laufen.
+ *   6. den Provider durch die Sequenz fahren: aufloesen, Fakten, Quelltext,
+ *      IR, dazu Uebersicht, Pfadlauf und Suche als Zugabe
+ *   7. abraeumen, Restprozesse zaehlen, verification/w1/provider.json schreiben

+ * W2a-Smoke: das Chrome, der Baum und der Reader an einem echten Server.
+ *
+ * Was hier bewiesen wird, kann kein Unit-Test beweisen: dass die gebaute Seite
+ * aus dist/ in einem echten Browser ein CODEATLAS-Terminal zeigt, dass der Baum
+ * aus /api/tree kommt und nicht aus einer Attrappe, dass ein Klick auf eine
+ * Datei echten Quelltext vom Server in einen read-only Monaco bringt, und dass
+ * eine Datei, die der Server abschneidet, im Reader als abgeschnitten
+ * dasteht.
+ *
+ * Ablauf:
+ *   1. `npm run build` (schreibt den Versions-Chip zur Buildzeit hinein)
+ *   2. isoliertes HOME, beide Fixtures ueber die CLI indizieren
+ *   3. C-Server auf einem freien Port >= 4230 starten
+ *   4. dist/ auf einem zweiten Port ausliefern, /rpc und /api dorthin proxen
+ *      (der Server nimmt keinen fremden Origin an, siehe tools/lib/static-proxy.mjs)
+ *   5. Chromium, mit abgeklemmter Namensaufloesung und einer Route-Sperre, die
+ *      jede Anfrage ausserhalb des eigenen Ursprungs abbricht und mitschreibt
+ *   6. Klickstrecke: Baum lesen, Ordner auf und zu, Datei oeffnen, Editor
+ *      pruefen, dagegen tippen, Screenshots
+ *   7. grosse Datei: Kappung im Reader messen, Fenster-Semantik direkt an /rpc
+ *   8. abraeumen, Restprozesse zaehlen, verification/w2/reader.json schreiben
+ *
+ * Das Ganze laeuft unter dem Netz-Deny-Gate (npm run smoke:w2a).

+/*
+ * W2b-Smoke: der Semantic Twin an einem echten Server, ueber eine echte
+ * Caret-Strecke.
+ *
+ * Was hier bewiesen wird, kann kein Unit-Test beweisen. Die Unit-Tests zeigen,
+ * dass das portierte Render-Modell aus einer aufgezeichneten IR dieselben vier
+ * Tiefen baut wie im Referenzprojekt. Sie sagen nichts darueber, ob in einem
+ * echten Browser ein Klick in eine Zeile ein Symbol aufloest, ob der Graph
+ * dieses Servers die sechs Schritte von createUser hergibt, ob die Nummern im
+ * Rand des Editors zu der Liste im Panel passen, und ob ein zweiter Klick
+ * innerhalb desselben Symbols den Server noch einmal fragt.
+ *
+ * Ablauf, wie bei smoke-w2a:
+ *   1. `npm run build`
+ *   2. isoliertes HOME, fixtures/atlas-sample ueber die CLI indizieren
+ *   3. C-Server auf einem freien Port >= 4240 starten
+ *   4. dist/ auf einem zweiten Port ausliefern, /rpc und /api dorthin proxen
+ *   5. Chromium ohne Aussenwelt, plus Route-Sperre
+ *   6. Klickstrecke: Datei oeffnen, in die validateUser-Zeile klicken, Panel
+ *      messen, Tiefen durchfahren, Beleg aufklappen, Caret versetzen, folgen
+ *   7. abraeumen, Restprozesse zaehlen, verification/w2/twin.json schreiben
+ *
+ * Das Ganze laeuft unter dem Netz-Deny-Gate (npm run smoke:w2b).

+/*
+ * W3-Smoke: die Galaxie an einem echten Server, und der Fokus in beide
+ * Richtungen.
+ *
+ * Was hier bewiesen wird, koennen die Unit-Tests nicht beweisen. Sie zeigen an
+ * erfundenen Knoten, dass ein qualifizierter Name den richtigen Punkt findet,
+ * dass Nachbarn Nachbarn sind und dass die Rangfolge der Suche dieselbe ist
+ * wie im Referenzprojekt. Sie sagen nichts darueber, ob dieser Server ein
+ * Layout liefert, ob ein Browser die Szene ueberhaupt zeichnet, ob ein
+ * getipptes Wort in der Fusszeile zu einer Liste wird, ob ein Enter darauf die
+ * Datei oeffnet und die Kamera bewegt, und ob ein Klick in die Galaxie
+ * zurueckfuehrt in den Reader.
+ *
+ * Ablauf, wie bei smoke-w2b:
+ *   1. `npm run build`
+ *   2. isoliertes HOME, fixtures/atlas-sample ueber die CLI indizieren
+ *   3. C-Server auf einem freien Port >= 4250 starten
+ *   4. dist/ auf einem zweiten Port ausliefern, /rpc und /api dorthin proxen
+ *      (auch /api/layout: die Galaxie holt ihr Layout ueber genau diese Route)
+ *   5. Chromium ohne Aussenwelt, plus Route-Sperre
+ *   6. Klickstrecke: Layout abwarten, "createUser" tippen, Enter, dann einen
+ *      Knoten in der Galaxie anklicken
+ *   7. abraeumen, Restprozesse zaehlen, verification/w3/galaxy.json schreiben
+ *
+ * Das Ganze laeuft unter dem Netz-Deny-Gate (npm run smoke:w3).
+ *
+ * ## WebGL im Headless-Browser
+ *
+ * Headless-Chromium hat keine GPU. Ohne Zutun faellt es auf SwiftShader
+ * zurueck, und seit Chrome 127 verlangt dieser Rueckfall ein ausdrueckliches
+ * Flag. Beide Flags stehen unten in CHROMIUM_ARGS und sind der Grund, warum
+ * dieser Lauf headless bleiben kann: `--use-angle=swiftshader` waehlt den
+ * Software-Renderer, `--enable-unsafe-swiftshader` erlaubt ihn. Ob er
+ * wirklich gegriffen hat, wird nicht vermutet, sondern gemessen: der Bericht
+ * traegt den Renderer-String aus WEBGL_debug_renderer_info und die Zahl der
+ * nicht schwarzen Pixel des gerenderten Canvas.

+ * W4a-Smoke: die Einstiegsmodi an einem echten Server.
+ *
+ * Was hier bewiesen wird, koennen die Unit-Tests nicht beweisen. Sie zeigen an
+ * einer eingefrorenen Fixture, dass der Topsort dieselbe Ordnung liefert, dass
+ * ein Closure-Walk terminiert und dass eine Karte ihre Tasten beschriftet. Sie
+ * sagen nichts darueber, ob dieser Server eine Zusammenfassung liefert, aus der
+ * eine Fuehrung entsteht, ob ein Enter im Browser den Reader bewegt, ob der Twin
+ * einem Schritt folgt, ob die stille Anzeige dabei steigt und ob der Satz ueber
+ * einen gekappten Walk wirklich dort steht, wo ein Leser ihn saehe.
+ *
+ * Ablauf, wie bei smoke-w3:
+ *   1. `npm run build`
+ *   2. isoliertes HOME, fixtures/atlas-sample ueber die CLI indizieren
+ *   3. C-Server auf einem freien Port >= 4260 starten
+ *   4. dist/ auf einem zweiten Port ausliefern, /rpc und /api dorthin proxen
+ *   5. Chromium ohne Aussenwelt, plus Route-Sperre
+ *   6. Klickstrecke: Frage, Projekt-Fuehrung, Vorwaerts-Walk, Deckel-Beweis
+ *   7. abraeumen, Restprozesse zaehlen, verification/w4/tours.json schreiben
+ *
+ * Das Ganze laeuft unter dem Netz-Deny-Gate (npm run smoke:w4a).
+ *
+ * ## Der Deckel-Beweis
+ *
+ * An einem Projekt mit zehn Dateien kappt der Vorgabe-Deckel von fuenfzehn
+ * Symbolen nichts, und ein Satz, den man nie sieht, ist kein bewiesener Satz.
+ * Also wird der Vorwaerts-Walk zweimal gefahren: einmal mit den Vorgaben, wo am
+ * Ende KEIN Deckel-Satz stehen darf, und einmal mit `?codeatlasClosureCap=3`,
+ * wo er stehen MUSS und die Zahlen des Aufrufs nennen muss. Erst beide
+ * Richtungen zusammen sind der Beweis; eine davon allein waere entweder eine
+ * unbewiesene Behauptung oder ein Satz, der immer dasteht.

+/*
+ * W4b-Smoke: der BUG-Assistent und der Blast-Radius an einem echten Server.
+ *
+ * Was hier bewiesen wird, koennen die Unit-Tests nicht beweisen. Sie zeigen an
+ * erfundenen Zeilen, dass eine Divergenz die Differenz zweier Mengen ist und
+ * dass ein Ref mit zwei Punkten abgelehnt wird. Sie sagen nichts darueber, ob
+ * dieser Server eine eingespielte Aufzeichnung wieder herausgibt, ob der Satz
+ * ueber die fehlende Aufzeichnung dort steht, wo ein Leser ihn saehe, ob ein
+ * Klick auf einen Hop den Reader bewegt, ob eine echte Aenderung an einer echten
+ * Datei eine Kachelzeile und ein Wort mit Begruendung ergibt, und ob bei einem
+ * kaputten Ref wirklich nichts auf den Draht geht.
+ *
+ * Ablauf:
+ *   1. `npm run build`
+ *   2. isoliertes HOME, eigenes Rendezvous-Verzeichnis, KOPIE der Fixture
+ *   3. git init + Basis-Commit in der Kopie, dann indizieren
+ *   4. C-Server auf einem freien Port >= 4270, dist/ auf einem zweiten
+ *   5. Chromium ohne Aussenwelt, plus Route-Sperre
+ *   6a. Assistent ohne Aufzeichnung: der ehrliche Satz und die Anleitung
+ *   6b. ingest_traces ueber die CLI, danach Assistent mit Divergenz
+ *   6c. eine exportierte Funktion dazu, Reindex, dann der Blast-Radius
+ *   7. abraeumen, Restprozesse zaehlen, zwei JSON schreiben
+ *
+ * Das Ganze laeuft unter dem Netz-Deny-Gate (npm run smoke:w4b).
+ *
+ * ## Drei Entscheidungen, die man sonst raten muesste
+ *
+ * **Die Fixture wird kopiert, nie angefasst.** Der Impact-Beweis braucht eine
+ * echte Aenderung an einer echten Datei; fixtures/atlas-sample ist die Grundlage
+ * von vier anderen Beweislaeufen und bleibt byte-identisch. Alles passiert in
+ * einem mkdtemp-Verzeichnis, das am Ende wieder verschwindet.
+ *
+ * **Die Kopie bekommt ein eigenes git-Repository.** `detect_changes` vergleicht
+ * gegen git-Refs, also braucht die Kopie einen Basis-Commit, bevor irgendetwas
+ * geaendert wird. Es wird ausschliesslich in der Kopie initialisiert und
+ * committet; kein fremdes Repository wird beruehrt.
+ *
+ * **CBM_RUNTIME_DIR wird gesetzt.** Der Daemon des Servers und jede CLI
+ * verabreden sich in einem Rendezvous-Verzeichnis, das per Konto und nicht per
+ * HOME gilt: laeuft irgendwo sonst auf der Maschine eine CBM-Instanz mit einem
+ * anderen Cache-Verzeichnis, lehnt jede CLI dieses Laufs mit "the active account
+ * daemon uses a different cache directory" ab, und der Lauf waere nicht rot,
+ * sondern kaputt. Der Parameter (cbm/src/daemon/bootstrap.c) verlegt das
+ * Rendezvous in ein privates Verzeichnis dieses Laufs. Es liegt unter
+ * /private/tmp und nicht unter os.tmpdir(): die Pruefung des Verzeichnisses
+ * lehnt die pro-Benutzer-Ordner von macOS ab, /private/tmp ist die Vorgabe des
+ * Werkzeugs selbst.

+ * bewegt, und ob die wieder eingebaute Imports-Gruppe an einer echten Datei
+ * ueberhaupt einen Eintrag hat.
+ *
+ * ## Angepasst am 2026-08-29 (W5c), ohne eine Zusicherung aufzugeben
+ *
+ * Der Erklaerer ist seit W5c kein Kasten in der rechten Spalte mehr, sondern
+ * ein Overlay ueber der Editorflaeche (Nutzerfeedback: in der Spalte war er
+ * nicht zu lesen). Dieser Lauf misst weiterhin dieselben Felder mit derselben
+ * Bedeutung an denselben Testmarken, die mit umgezogen sind: `atlas-flow` mit
+ * seinen Zaehlern, `atlas-flow-box` als die Flaeche, deren Luminanz gemessen
+ * wird, `atlas-flow-participant`, `atlas-flow-arrow` und `atlas-flow-raise`.
+ * Drei Dinge sind anders, und alle drei sind der Umzug selbst:
+ *
+ *  - Der Erklaerer ist per Vorgabe ZU, weil eine Flaeche ueber dem Editor nicht
+ *    ungefragt aufgehen darf. Der Lauf oeffnet ihn also erst und misst den Kopf
+ *    danach, statt ihn im offenen Zustand vorzufinden.
+ *  - Die Position steht als "1 of 11" statt "1 / 11", wortgleich mit dem
+ *    Referenz-Explainer.
+ *  - Escape schliesst das Overlay, statt nur die Stepper-Sitzung zu beenden.
+ *    `escapeEndsSession` misst weiterhin, dass die Sitzung endet, und
+ *    zusaetzlich, dass die Flaeche vom Editor verschwindet.
+ *
+ * Ablauf:
+ *   1. `npm run build`
+ *   2. isoliertes HOME, eigenes Rendezvous-Verzeichnis
+ *   3. fixtures/atlas-sample indizieren (die Fixture wird nur gelesen)
+ *   4. C-Server auf einem freien Port >= 4280, dist/ auf einem zweiten
+ *   5. Chromium ohne Aussenwelt, plus Route-Sperre
+ *   6a. createUser fokussieren, Erklaerer oeffnen, Kopf-Knopf pruefen und schalten
+ *   6b. Stepper: Bild, STEPS-Zeile und Editor
+ *   6c. Escape beendet die Sitzung
+ *   6d. Pseudocode-Ansicht: Zeilen, Imports-Gruppe, Klick, ehrlicher Block
+ *   6e. Der Data-Block des Twin traegt die Imports-Antwort wieder
+ *   7. abraeumen, Restprozesse zaehlen, JSON und zwei Screenshots schreiben
+ *
+ * Das Ganze laeuft unter dem Netz-Deny-Gate (npm run smoke:w4c).
+ *
+ * ## Zwei Entscheidungen, die man sonst raten muesste
+ *
+ * **Die Fixture wird nur gelesen.** Dieser Lauf aendert keine Datei: er braucht
+ * keinen Diff, sondern nur einen Index. fixtures/atlas-sample bleibt
+ * byte-identisch, und es wird nichts kopiert, was nicht kopiert werden muss.
+ *
+ * **CBM_RUNTIME_DIR wird gesetzt.** Der Daemon des Servers und jede CLI
+ * verabreden sich in einem Rendezvous-Verzeichnis, das per Konto und nicht per
+ * HOME gilt: laeuft irgendwo sonst auf der Maschine eine CBM-Instanz mit einem
+ * anderen Cache-Verzeichnis, lehnt jede CLI dieses Laufs ab, und der Lauf waere
+ * nicht rot, sondern kaputt. Wortgleich mit tools/smoke-w4b.mjs.

+/*
+ * W4d-Smoke: der Explorer zeigt die Datei-Wahrheit, und was fehlt, wird
+ * gemessen statt vermutet.
+ *
+ * Was hier bewiesen wird, koennen die Unit-Tests nicht beweisen. Sie zeigen an
+ * abgeschriebenen Antworten, dass der Join keine Stufe erfindet und dass ein
+ * Konflikt zugunsten des Problems entschieden wird. Sie sagen nichts darueber,
+ * WELCHE Liste der Server fuer eine kaputte, eine binaere und eine
+ * gitignorierte Datei wirklich fuellt. Genau das ist die Frage dieses Laufs,
+ * und sie wird beantwortet, indem die Faelle praepariert, indiziert, an der
+ * Serverantwort abgelesen und danach im Baum wiedererkannt werden.
+ *
+ * Ablauf:
+ *   1. `npm run build`
+ *   2. isoliertes HOME, eigenes Rendezvous-Verzeichnis
+ *   3. eine KOPIE von fixtures/atlas-sample im Scratch, mit vier Praeparaten:
+ *      saubere TS-Datei (unveraendert aus der Fixture), kaputte TS-Datei,
+ *      Binaerdatei mit Nicht-Code-Endung, .gitignore samt gitignorierter Datei
+ *   4. die Kopie indizieren (die Fixture selbst bleibt byte-identisch)
+ *   5. C-Server auf einem freien Port >= 4320, dist/ auf einem zweiten
+ *   6. die Wahrheit am Server ablesen: index_status, check_index_coverage
+ *      (scopes und paths), /api/tree rekursiv
+ *   7. Chromium ohne Aussenwelt, plus Route-Sperre
+ *   8a. Baum aufklappen und Zeile fuer Zeile gegen das Gemessene halten
+ *   8b. Galaxy-Legende: Eintraege, Klappen, Ueberleben des Reloads
+ *   8c. Reader: partielle Datei mit Inhalt und Notiz, inhaltslose Datei mit
+ *       ehrlicher Erklaerung statt Fehler
+ *   8d. Frische: eine Datei nach dem Index aendern und die Notiz lesen
+ *   9. abraeumen, Restprozesse zaehlen, JSON und Screenshot schreiben
+ *
+ * Das Ganze laeuft unter dem Netz-Deny-Gate (npm run smoke:w4d).
+ *
+ * ## Drei Entscheidungen, die man sonst raten muesste
+ *
+ * **Praepariert wird nur an der Kopie.** fixtures/atlas-sample bleibt
+ * byte-identisch; eine kaputte Datei in der Fixture waere ein Praeparat, das
+ * jeder spaetere Lauf mitschleppt, ohne davon zu wissen.
+ *
+ * **Die Binaerdatei traegt feste Bytes.** Kein Zufall: derselbe Lauf soll
+ * zweimal dieselbe Datei erzeugen, sonst waere die Groesse in der Antwort des
+ * Servers von Lauf zu Lauf eine andere Zahl.
+ *
+ * **CBM_RUNTIME_DIR wird gesetzt.** Der Daemon des Servers und jede CLI
+ * verabreden sich in einem Rendezvous-Verzeichnis, das per Konto und nicht per
+ * HOME gilt: laeuft irgendwo sonst auf der Maschine eine CBM-Instanz mit einem
+ * anderen Cache-Verzeichnis, lehnt jede CLI dieses Laufs ab, und der Lauf waere
+ * nicht rot, sondern kaputt. Wortgleich mit tools/smoke-w4b.mjs.

+/*
+ * W4e-Smoke: die Hierarchie des Vorwaerts-Walks, in einem echten Browser.
+ *
+ * Was hier bewiesen wird, koennen die Unit-Tests nicht beweisen. Sie zeigen an
+ * einem erfundenen Walk, dass die Projektion zweimal dasselbe Bild baut, dass
+ * die Spalte am Hop haengt und dass keine Kante verschwindet. Sie sagen nichts
+ * darueber, ob dieser Server einen Walk liefert, der tief genug fuer eine
+ * Hierarchie ist, ob das Panel beim Waehlen eines Einstiegspunkts von selbst
+ * umschaltet, ob DIESELBE Szene die Projektion zeichnet, ohne ihren
+ * WebGL-Kontext wegzuwerfen, ob der Ring dem Schritt folgt und ob der Kopf
+ * dabei die Wahrheit sagt.
+ *
+ * Ablauf, wie bei smoke-w4a und smoke-w4d:
+ *   1. `npm run build`
+ *   2. isoliertes HOME, eigenes Rendezvous-Verzeichnis
+ *   3. fixtures/atlas-sample indizieren (nur gelesen, nichts praepariert)
+ *   4. C-Server auf einem freien Port >= 4330, dist/ auf einem zweiten
+ *   5. Chromium ohne Aussenwelt, plus Route-Sperre, plus die beiden
+ *      Software-GL-Flags
+ *   6a. frische App: das Panel steht auf galaxy und sagt, dass ihm ein Walk
+ *       fehlt
+ *   6b. Einstiegsmodus, createUser waehlen: das Panel schaltet von selbst um
+ *   6c. die Projektion vermessen: Knoten, Ebenen, Wurzel, Spalten je Hop
+ *   6d. den Canvas markieren und fotografieren
+ *   6e. Enter: der Ring wandert auf einen anderen Knoten
+ *   6f. Klick auf einen Knoten: Reader und Twin folgen
+ *   6g. Chip galaxy: der Zaehler-Kopf ist zurueck, und es ist derselbe Canvas
+ *       mit einem lebenden Kontext
+ *   6h. der Deckel-Beweis: derselbe Walk mit ?codeatlasClosureCap=3, der Kopf
+ *       muss den Deckel nennen
+ *   7. abraeumen, Restprozesse zaehlen, JSON und Screenshot schreiben
+ *
+ * Das Ganze laeuft unter dem Netz-Deny-Gate (npm run smoke:w4e).
+ *
+ * ## Drei Entscheidungen, die man sonst raten muesste
+ *
+ * **Der gleiche-Canvas-Beweis ist eine Markierung, kein Vergleich von Bildern.**
+ * Vor dem Umschalten bekommt das Canvas-Element ein Attribut und eine Referenz
+ * in einer globalen Variable; nach dem Umschalten muessen beide noch am selben
+ * Element haengen und der WebGL-Kontext darf nicht verloren sein. Zwei
+ * Screenshots zu vergleichen wuerde messen, ob sich das Bild geaendert hat, und
+ * das soll es ja.
+ *
+ * **Der Kopf wird zweimal gelesen, mit und ohne Deckel.** Ein Satz ueber eine
+ * Grenze, den man nie sieht, ist kein bewiesener Satz, und einer, der immer
+ * dasteht, ist keine Aussage. Also einmal mit den Vorgaben, wo er FEHLEN muss,
+ * und einmal mit `?codeatlasClosureCap=3`, wo er stehen und seine Zahlen nennen
+ * muss. Dieselbe Beweisform wie in smoke-w4a.
+ *
+ * **CBM_RUNTIME_DIR wird gesetzt.** Der Daemon des Servers und jede CLI
+ * verabreden sich in einem Rendezvous-Verzeichnis, das per Konto und nicht per
+ * HOME gilt: laeuft irgendwo sonst auf der Maschine eine CBM-Instanz mit einem
+ * anderen Cache-Verzeichnis, lehnt jede CLI dieses Laufs ab, und der Lauf waere
+ * nicht rot, sondern kaputt. Wortgleich mit tools/smoke-w4b.mjs und -w4d.

+/*
+ * W5a-Smoke: der Opt-out ist ein Produktmodus, der Sidecar sagt die Wahrheit
+ * ueber seinen Prozess, und eine committete Policy schlaegt jede Praeferenz.
+ *
+ * Was hier bewiesen wird, koennen die Unit-Tests nicht beweisen. Sie zeigen an
+ * erfundenen Antworten, dass `probeSidecar` drei Adressen fragt und keine
+ * vierte, und dass die Vorrangregel in jeder Kombination dasselbe ergibt. Sie
+ * sagen nichts darueber, ob eine frisch geladene Seite mit leerem
+ * localStorage wirklich KEIN Byte Richtung 4141 schickt, ob der gebaute
+ * llama-server aus vendor/llama ein Modell laedt und sich im Panel wiederfindet,
+ * ob der Zustand nach dem Beenden ehrlich zurueckfaellt, und ob eine
+ * policy.json im indizierten ZIELprojekt ueber den vorhandenen Lese-Weg
+ * ueberhaupt ankommt.
+ *
+ * Ablauf, wie bei smoke-w4d und smoke-w4e:
+ *   1. `npm run build`
+ *   2. isoliertes HOME, eigenes Rendezvous-Verzeichnis
+ *   3. zwei Projekte indizieren: fixtures/atlas-sample (nur gelesen) und eine
+ *      KOPIE davon mit .codeatlas/policy.json {"llm":"deny"}
+ *   4. C-Server auf einem freien Port >= 4300, dist/ auf einem zweiten
+ *   5. Chromium ohne Aussenwelt, mit einer Route-Sperre, die 127.0.0.1:4141
+ *      ausdruecklich DURCHLAESST und mitzaehlt
+ *   6a. frische App: llm aus, und der Zaehler auf 4141 steht auf null
+ *   6b. einschalten ohne Prozess: die Anleitung nennt llm/start.sh
+ *   6c. llm/start.sh class-a, warten auf ready: Modell und Chip
+ *   6d. llm/stop.sh: der Zustand faellt ehrlich zurueck
+ *   6e. das Policy-Projekt, mit einer VORHER auf "an" gesetzten Praeferenz
+ *   7. abraeumen, Restprozesse zaehlen (auch llama-server), JSON und Bilder
+ *
+ * Das Ganze laeuft unter dem Netz-Deny-Gate (npm run smoke:w5a). 4141 ist
+ * Loopback und zaehlt dort nicht als Verstoss; das ist der Punkt, an dem sich
+ * "air-gapped" und "lokales Modell" nicht widersprechen.
+ *
+ * ## Drei Entscheidungen, die man sonst raten muesste
+ *
+ * **Die Null wird zweimal gemessen, aus zwei Richtungen.** Der Route-Handler im
+ * Browser zaehlt jede Anfrage an 4141, und der Griff `__atlasLlm.probes` zaehlt
+ * jeden Aufruf von `probeSidecar` in der Anwendung. Eine der beiden Zahlen
+ * allein waere angreifbar: der Handler saehe eine Anfrage nicht, die eine
+ * andere Schicht stellt, und der Zaehler saehe eine nicht, die an ihm vorbei
+ * geht. Beide muessen null sein, solange das LLM aus ist.
+ *
+ * **Die Praeferenz des Policy-Projekts wird VOR dem Laden auf "an" gesetzt.**
+ * Ein Schalter, den man erst nach dem Sperren drueckt, beweist nur, dass ein
+ * Klick nichts tut. Hier steht die Praeferenz schon im Speicher, wenn die Seite
+ * das erste Mal laedt: die Policy muss also etwas ueberstimmen, das es
+ * wirklich gibt, und nicht nur einen Klick abfangen.
+ *
+ * **Die Policy-Datei liegt in einer KOPIE der Fixture.** fixtures/atlas-sample
+ * ist Beweisgrundlage von vier fruehereren Laeufen und bleibt byte-identisch.
+ * Eine Datei dort anzulegen waere eine Aenderung an der Grundlage, mit der die
+ * anderen Laeufe verglichen werden.

+/*
+ * W5b-Smoke: die Kommandozeile ist der Chat, die Zitate sind Knoepfe, und der
+ * Compiler haelt sich an die Karten, die er selbst geschrieben hat.
+ *
+ * Was hier bewiesen wird, koennen die Unit-Tests nicht beweisen. Sie zeigen an
+ * erfundenen Antworten, dass der Klassifikator deterministisch ist, dass die
+ * Karten unter dem Budget bleiben und dass ein `[K3]` ein Knopf wird. Sie sagen
+ * nichts darueber, ob eine gebaute Seite mit einem echten Sidecar auf 4141 eine
+ * Frage aus der Fusszeile beantwortet, ob ein Klick auf ein Zitat wirklich in
+ * der Zieldatei landet, ob der Schalter "aus" die Anfrage wirklich verhindert,
+ * und ob der refine-Knopf ohne Modell wirklich fehlt.
+ *
+ * Ablauf, wie bei smoke-w5a:
+ *   1. `npm run build`
+ *   2. isoliertes HOME, eigenes Rendezvous-Verzeichnis
+ *   3. fixtures/atlas-sample indizieren (nur gelesen)
+ *   4. C-Server auf einem freien Port >= 4310, dist/ auf einem zweiten
+ *   5. Chromium ohne Aussenwelt, mit einer Route-Sperre, die 127.0.0.1:4141
+ *      ausdruecklich DURCHLAESST und mitzaehlt
+ *   6a. LLM aus: die Frage landet im Panel, aber KEIN Byte geht an 4141
+ *   6b. llm/start.sh mit dem Klasse-A-Sieger, warten auf ready
+ *   6c. "Wer ruft createUser?" in die Kommandozeile, Enter
+ *   6d. Zitat anklicken: der Reader steht in der Zieldatei
+ *   6e. Karten aufklappen, Tiefenschalter lesen und umstellen
+ *   6f. refine: Knopf da bei ready, und der echte Validator lehnt Unsinn ab
+ *   6g. den Fokus ueber den Caret aufloesen, das belegen, und dann eine Frage
+ *       ohne Karte: der vereinbarte Satz faellt, ohne Anfrage
+ *   7. abraeumen, Restprozesse zaehlen (auch den Sidecar), JSON und Bild
+ *
+ * Das Ganze laeuft unter dem Netz-Deny-Gate (npm run smoke:w5b). 4141 ist
+ * Loopback und zaehlt dort nicht als Verstoss.
+ *
+ * ## Drei Entscheidungen, die man sonst raten muesste
+ *
+ * **Der Klasse-A-Sieger kommt aus verification/w5/eval.json.** Nicht aus einer
+ * Konstante hier: das Kopf-an-Kopf-Rennen entscheidet, welches Modell das
+ * Produkt fahren soll, und ein Beweislauf, der ein anderes faehrt, beweist
+ * etwas ueber ein Modell, das niemand gewaehlt hat. Fehlt die Datei, bricht der
+ * Lauf ab statt still auf 1b zu fallen.
+ *
+ * **Die Null wird zweimal gemessen, so wie in W5a.** Der Route-Handler zaehlt
+ * jede Anfrage an 4141, und `__atlasLlm.probes` zaehlt jeden Aufruf der Anwendung.
+ * Beide muessen null sein, solange das Modell aus ist, auch nachdem eine Frage
+ * gestellt wurde.
+ *
+ * **Die Ablehnung einer kaputten Umformulierung wird am echten Validator
+ * gemessen.** `__atlasChat.validateRefine` ruft dieselbe Funktion, die der Knopf
+ * ruft, mit einer absichtlich falschen Antwort. Ein Lauf, der die Regel
+ * nachbaut, prueft seine eigene Kopie und nicht das Produkt.
+ *
+ * **Die Frage ohne Karte steht ganz am Ende, und der Fokus wird vorher
+ * aufgeloest.** Seit W7c antwortet der Chat auf einen nicht aufloesbaren
+ * @mention zum Symbol im Fokus, wenn eines dasteht, und sagt in einer eigenen
+ * Zeile, dass er das getan hat. Der vereinbarte Keine-Karte-Satz gilt dem
+ * anderen Fall: kein aufloesbares Symbol UND kein Fokus. Diese Frage an einer
+ * Stelle zu stellen, an der noch das Subjekt eines frueheren Abschnitts im Twin
+ * steht, wuerde also den falschen Fall messen. Sie steht deshalb hinter allen
+ * Abschnitten, die ein Subjekt brauchen; davor wandert der Caret ueber die
+ * Oberflaeche auf eine Zeile, in der keine Funktion steht, und dass der Twin
+ * danach wirklich leer ist, wird gemessen und mitgeschrieben statt angenommen.

+/*
+ * W5c-Smoke: der Flow-Erklaerer als Overlay, der Status-Punkt an jeder Datei,
+ * das dauerhaft sichtbare Graph-Panel, die lesbare Hierarchie und die
+ * scrollende Tab-Leiste, alles an einem echten Server.
+ *
+ * Vier Wellen Nutzerfeedback vom 2026-08-29 stehen dahinter, und keine davon
+ * laesst sich in jsdom beantworten. Die Unit-Tests zeigen an aufgezeichneten
+ * Fakten, dass die Geometrie stimmt und dass die Liste die Zeilen des Blocks
+ * traegt. Sie koennen nicht zeigen, dass NICHTS vor dem Overlay liegt (das ist
+ * eine Frage an `elementFromPoint` in einem Browser mit echtem Layout), dass
+ * der Grund wirklich dunkel gemalt wird (eine Frage an die gerechnete
+ * Hintergrundfarbe), dass das Graph-Panel waehrend einer Fuehrung im Viewport
+ * steht (eine Frage an getBoundingClientRect), dass sich keine zwei
+ * Beschriftungen der Hierarchie ueberlagern (eine Frage an die Kaesten, die die
+ * Szene wirklich gezeichnet hat) und dass die Tab-Leiste bei elf offenen
+ * Dateien scrollt statt umzubrechen.
+ *
+ * Ablauf:
+ *   1. `npm run build`
+ *   2. isoliertes HOME, eigenes Rendezvous-Verzeichnis
+ *   3. fixtures/atlas-sample indizieren (die Fixture wird nur gelesen)
+ *   4. C-Server auf einem freien Port >= 4360, dist/ auf einem zweiten
+ *   5. Chromium ohne Aussenwelt, plus Route-Sperre
+ *   6a. Legende: im frischen Browser default zu
+ *   6b. Explorer: der Status-Punkt an jeder Datei, auch am Gutfall
+ *   6c. Tab-Leiste: elf Dateien oeffnen, scrollen, nichts ueberlagert
+ *   6d. Overlay auf Tiefe 0
+ *   6e. Overlay auf Tiefe 3: Diagramm, Liste, Stepper, Ehrlichkeit, Escape
+ *   6f. Twin-Ueberlaenge: das Graph-Panel bleibt stehen
+ *   6g. Topsort-Fuehrung: die Galaxy folgt und bleibt im Bild
+ *   6h. Entry-Walk createUser (gross) und getOrder (klein): Hierarchie lesbar
+ *   7. abraeumen, Restprozesse zaehlen, JSON und zwei Screenshots schreiben
+ *
+ * Das Ganze laeuft unter dem Netz-Deny-Gate (npm run smoke:w5c).
+ *
+ * ## Drei Entscheidungen, die man sonst raten muesste
+ *
+ * **Die Fixture wird nur gelesen.** Dieser Lauf aendert keine Datei: er braucht
+ * keinen Diff, sondern nur einen Index. fixtures/atlas-sample bleibt
+ * byte-identisch.
+ *
+ * **CBM_RUNTIME_DIR wird gesetzt.** Der Daemon des Servers und jede CLI
+ * verabreden sich in einem Rendezvous-Verzeichnis, das per Konto und nicht per
+ * HOME gilt. Ohne das waere ein Lauf neben einer anderen CBM-Instanz nicht rot,
+ * sondern kaputt. Wortgleich mit tools/smoke-w4c.mjs.
+ *
+ * **Die Ueberlappung der Beschriftungen wird in WELTkoordinaten gemessen.** Die
+ * Namen der Szene sind Sprites in einem WebGL-Bild und haben kein DOM-Rechteck.
+ * Die Ebene, die sie zeichnet, meldet die Kaesten, die sie wirklich gesetzt hat
+ * (NodeLabels.onLayout). Alle Knoten dieser Ansicht liegen auf z=0 und die
+ * Kamera steht frontal davor, also ist eine Ueberlappung dieser Rechtecke genau
+ * eine Ueberlappung auf dem Schirm. Eine zweite Rechnung im Beweislauf waere
+ * eine zweite Wahrheit ueber dieselbe Schrift.

+/*
+ * W6a-Smoke: die GANZE Klickstrecke des Produkts, in einem Lauf, ohne Netz.
+ *
+ * Bis W5c hatte jeder Zyklus seinen eigenen Beweislauf, und jeder davon fuhr
+ * ein Stueck der Oberflaeche. Zusammen decken sie alles ab, und trotzdem fehlt
+ * eine Aussage: dass die Stuecke NEBENEINANDER funktionieren. Ein Panel, das
+ * allein gruen ist und neben dem Nachbarn ueberlaeuft, ist in keinem der
+ * einzelnen Laeufe rot. Dieser Lauf faehrt darum alles hintereinander, in
+ * einem Browser, auf einem Server, mit einem Index, und stellt an jedem Halt
+ * dieselben drei Fragen an das Bild.
+ *
+ * Ablauf:
+ *   1. `npm run build`
+ *   2. isoliertes HOME, eigenes Rendezvous-Verzeichnis
+ *   3. drei Projekte indizieren: die Fixture (nur gelesen), die grosse Fixture
+ *      fuer die gekappte Datei (nur gelesen), und eine KOPIE der Fixture mit
+ *      eigenem git-Repository und einer echten Aenderung fuer den Blast-Radius
+ *   4. C-Server auf einem freien Port >= 4340, dist/ auf einem zweiten
+ *   5. Chromium ohne Aussenwelt, plus Route-Sperre; 127.0.0.1:4141 ist
+ *      ausdruecklich erlaubt und wird mitgezaehlt
+ *   6. die Strecke, Halt fuer Halt und jeder benannt
+ *   7. abraeumen, Restprozesse zaehlen, drei JSON und die Bilder schreiben
+ *
+ * Das Ganze laeuft unter dem Netz-Deny-Gate (npm run smoke:w6).
+ *
+ * ## Fuenf Entscheidungen, die man sonst raten muesste
+ *
+ * **Drei Projekte statt eines.** Die Strecke braucht drei verschiedene
+ * Ausgangslagen: eine unberuehrte Fixture fuer alles Lesende, eine grosse Datei
+ * fuer die Kappungszeile (die Aussage "hier hoert das Geladene auf" ist an einer
+ * 42-Zeilen-Datei nicht zu sehen), und eine geaenderte Kopie fuer die
+ * Aenderungsansicht. fixtures/ bleibt byte-identisch; die Kopie liegt in einem
+ * mkdtemp-Verzeichnis und verschwindet am Ende.
+ *
+ * **Der Lauf misst die Netzstille selbst.** Warum er sie nicht vom Gate
+ * abschreibt, steht im Kopf von tools/lib/socket-sampler.mjs. Kurz: das Gate
+ * schreibt sein Ergebnis erst, wenn dieser Lauf schon vorbei ist.
+ *
+ * **Das Lesbarkeits-Gate laeuft an JEDEM Halt, nicht an ausgewaehlten.** Die
+ * Regeln stehen in tools/lib/readability.mjs. Ein Halt, an dem nur ein
+ * Screenshot faellt, ist ein Halt, an dem niemand hingesehen hat.
+ *
+ * **Die warme Twin-Messung nimmt zehn VERSCHIEDENE Symbole.** Dasselbe Symbol
+ * zweimal zu oeffnen misst den Cache in src/twin/ir-cache.ts und nicht den
+ * Server. Warm heisst hier: der Server laeuft, sein Index ist gelesen, seine
+ * Seiten sind im Cache des Betriebssystems. Gemessen wird vom Klick auf den
+ * Treffer bis zu dem Moment, in dem der Twin das neue Subjekt fertig zeigt; das
+ * Tippen und die Entprellung davor stehen als `searchOverlayMs` getrennt.
+ *
+ * **Der Versions-Chip wird abgelesen, nicht gerechnet.** Er zeigt seit W6a nur
+ * die Fassung; der Zustand des Arbeitsbaums steht als eigenes Element daneben
+ * (src/app/build-info.ts). Beides wird gelesen und beides steht im Ergebnis,
+ * damit ein Bild dieses Laufs einer Fassung UND einem Baumzustand zuzuordnen
+ * ist.

+/*
+ * W7a-Smoke: die entkernte Menuezeile, die eingebaute Hilfeseite, die
+ * ehrlichen Twin-Saetze und die Kommandozeile, die Tippen wirklich annimmt.
+ *
+ * Was hier bewiesen wird, kann kein Unit-Test beweisen. Die Unit-Tests zeigen,
+ * dass der Katalog keine Attrappe mehr traegt, dass die Hilfe ihre sieben
+ * Abschnitte in der richtigen Reihenfolge baut und dass ein blanker Buchstabe
+ * kein Kuerzel mehr ist. Sie sagen nichts darueber, ob im gebauten Programm
+ * wirklich nur noch verdrahtete Punkte in der Zeile stehen, ob ein Klick auf
+ * [?]help die Seite aufschlaegt, ob die Taste `?` dasselbe tut, ob Escape sie
+ * schliesst, ob sich in ihr etwas ueberlagert oder aus seinem Kasten ragt, und
+ * vor allem: ob das Wort "create", ohne vorher zu klicken getippt, in der
+ * Kommandozeile ankommt, statt ueber sein `c` ein Panel aufzuschlagen. Genau
+ * das war der Nutzerbefund vom 2026-08-29.
+ *
+ * Ablauf:
+ *   1. `npm run build`
+ *   2. isoliertes HOME, eigenes Rendezvous-Verzeichnis (CBM_RUNTIME_DIR)
+ *   3. fixtures/atlas-sample indizieren (die Fixture wird nur gelesen)
+ *   4. C-Server auf einem freien Port >= 4370, dist/ auf einem zweiten
+ *   5. Chromium ohne Aussenwelt, plus Route-Sperre
+ *   6a. Menuezeile lesen: was steht da, ist alles verdrahtet, gibt es noch
+ *       irgendwo einen "not wired"-Tooltip
+ *   6b. Hilfe per Klick, Abschnitte, Grenzen, Tastentabelle, Netz-Links,
+ *       Farbe, Lesbarkeit (auch durchgescrollt), Bild
+ *   6c. Hilfe per Taste `?`, zu per Escape
+ *   6d. Die Kommandozeile: tippen ohne Klick, kein Panel dabei, Fokus sichtbar,
+ *       Fokustaste, Ein-Zeichen-Hinweis, kein nativer Tooltip
+ *   6e. Der Twin: die beiden Linsen aufschalten und ihre Saetze lesen
+ *   7. abraeumen, Restprozesse zaehlen, verification/w7/help.json schreiben
+ *
+ * Das Ganze laeuft unter dem Netz-Deny-Gate (npm run smoke:w7a).
+ *
+ * ## Warum die verdrahtete Tastenliste aus dem QUELLTEXT gelesen wird
+ *
+ * `helpListsEveryShortcut` vergleicht die Tabelle der Hilfe nicht mit einer
+ * Liste, die in dieser Datei steht: das waere ein dritter Katalog und damit die
+ * dritte Gelegenheit, dass etwas auseinanderlaeuft. Gelesen wird die Verdrahtung
+ * selbst (src/app/shortcuts.ts, src/app/keyboard.ts, tour-player.ts,
+ * overlay-model.ts), und verglichen wird sie mit dem, was im Browser wirklich
+ * in der Tabelle steht.

+/*
+ * W7b-Smoke: eine Menuezeile aus sechs gleichen Knoepfen, Kuerzel, die sich im
+ * Zweifel selbst erklaeren, eine Suche, die vor dem Server antwortet, und die
+ * Messung der Vektorsuche des Servers.
+ *
+ * Drei Nutzerbefunde vom 2026-08-29 und eine Nutzerfrage stehen dahinter:
+ *
+ *  1. Die vier Eintraege der Atlas-Zeile sahen aus wie Text zwischen zwei
+ *     Bedienelementen. Gemessen wird deshalb nicht "sieht huebsch aus", sondern
+ *     die Struktur: dieselbe Klasse, dasselbe Element, dieselbe Polsterung,
+ *     derselbe Rahmen, derselbe Klammer-Buchstabe, und jeder der sechs laesst
+ *     sich mit der Maus UND mit Tab plus Enter ausloesen, mit sichtbarem Ring.
+ *  2. "alt plus letter funktioniert nur fuer atlas". An der laufenden Vorschau
+ *     nicht nachzustellen. Dieser Lauf misst deshalb zweierlei: dass alle fuenf
+ *     Kuerzel wirklich ausloesen, und dass der Griff am Fenster in der
+ *     EINFANGENDEN Phase haengt, also niemand ihm zuvorkommen kann. Das zweite
+ *     ist keine Behauptung ueber eine Zeile Quelltext, sondern eine Beobachtung:
+ *     ein Griff am Eingabefeld sieht das Ereignis nach dem Fenster, also schon
+ *     abbestellt. Dazu kommt der Tastentest der Hilfeseite, der dem Nutzer beim
+ *     naechsten Versuch sagt, was an SEINEM Geraet ankommt.
+ *  3. Die Suchvorschlaege erscheinen zu langsam. Gemessen wird die Strecke, die
+ *     der Leser spuert: vom letzten Tastendruck bis zur ersten sichtbaren Zeile,
+ *     ueber eine Reihe von Eingaben, plus der Serverweg daneben, plus die
+ *     Zusicherung, dass eine ueberholte Antwort nie gewinnt.
+ *  4. "Beruht die @-Suche auf einem Modell oder auf Embeddings?" Heute auf
+ *     keinem von beidem. Der Server kann aber Vektorsuche (mcp.c:410-417). Sie
+ *     wird hier gegen die Fixture gemessen, mit einem vorher festgelegten
+ *     Massstab, und das Urteil steht mit seinen Zahlen im Artefakt.
+ *
+ * Ablauf:
+ *   1. `npm run build`
+ *   2. isoliertes HOME, eigenes Rendezvous-Verzeichnis (CBM_RUNTIME_DIR)
+ *   3. fixtures/atlas-sample indizieren (nur gelesen), Modus `full`, weil die
+ *      Vektorsuche moderate/full verlangt
+ *   4. C-Server auf einem freien Port >= 4380, dist/ auf einem zweiten
+ *   5. Die Vektorsuche messen, direkt am Server, ohne Browser
+ *   6. Chromium ohne Aussenwelt, plus Route-Sperre
+ *      a. Menuezeile: Gestalt, Klick, Tastatur, Fokusring, Bild
+ *      b. Alt-Kuerzel, einfangende Phase, Tastentest der Hilfe
+ *      c. Suche: Messreihe, Praefix-Cache, ueberholte Antwort, Bild
+ *   7. abraeumen, Restprozesse zaehlen, verification/w7/search.json schreiben
+ *
+ * Das Ganze laeuft unter dem Netz-Deny-Gate (npm run smoke:w7b).

+/*
+ * W7c-Smoke: der Chat findet das Symbol, das der Leser meint, und das Panel
+ * benimmt sich wie ein Panel.
+ *
+ * Fuenf Nutzerbefunde vom 2026-08-29 stehen dahinter, zwei davon echte Fehler
+ * mit belegter Ursache:
+ *
+ *  1. "@createuser explain this funktion": das Such-Overlay zeigte createUser
+ *     (src/services/userService.ts L23), der Chat antwortete "the index holds no
+ *     symbol called 'createuser'". Zwei Lesungen desselben Index widersprachen
+ *     sich auf einem Bildschirm. Ursache: buchstabengetreue Vergleiche in
+ *     src/compiler/subject-resolver.ts.
+ *  2. Ein vorhandener Fokus wurde verschenkt: mention nicht aufloesbar hiess gar
+ *     kein Subjekt, obwohl der Twin auf createUser stand.
+ *  3. Mehrdeutigkeit (@create trifft zwei Symbole) wurde stillschweigend
+ *     aufgeloest statt angeboten.
+ *  4. Das Panel liess sich nicht in der Hoehe ziehen, die Kontext-Auswahl
+ *     scrollte weg, und der einzige Weg, es loszuwerden, kostete den Verlauf.
+ *  5. "[l]lm on/off" sagte nicht, dass das Modell lokal laeuft.
+ *
+ * ## Der eine Kunstgriff dieses Laufs, und warum er einer ist
+ *
+ * Das Produkt redet mit 127.0.0.1:4141, und dieser Port gehoert dem Nutzer:
+ * dort laeuft sein eigener Sidecar, waehrend dieser Lauf laeuft. Ihn zu belegen
+ * oder zu beenden waere ein Beweislauf, der die Arbeitsumgebung anfasst, die er
+ * beweisen soll. Also startet dieser Lauf sein EIGENES llama-server-Exemplar auf
+ * einem eigenen Port (>= 4420) und leitet die Anfragen dorthin um, und zwar an
+ * genau der Naht, an der die Anwendung sie selbst stellt: `window.fetch`. Alles
+ * davor (der Zustandsautomat des Sidecars, die Bereitschaftsprobe, der Chat, der
+ * Antwortvertrag) laeuft unveraendert.
+ *
+ * Nachgewiesen wird beides: dass die Antwort von einem echten Modell kommt UND
+ * dass an 4141 kein einziges Byte ging (`productPortRequests`, muss 0 sein). Der
+ * Route-Handler bricht eine Anfrage dorthin ausdruecklich ab, statt sie
+ * durchzulassen: ein Lauf, der den fremden Prozess "nur einmal kurz" fragt, hat
+ * ihn angefasst.
+ *
+ * ## Ablauf
+ *
+ *   1. `npm run build`
+ *   2. isoliertes HOME, eigenes Rendezvous-Verzeichnis (CBM_RUNTIME_DIR)
+ *   3. fixtures/atlas-sample indizieren (nur gelesen)
+ *   4. C-Server auf einem freien Port >= 4420, dist/ auf einem zweiten
+ *   5. eigener llama-server auf einem dritten, mit dem Klasse-A-Sieger
+ *   6. Chromium ohne Aussenwelt, mit Route-Sperre und der Umleitung oben
+ *      a. Modell an, dann eine Frage OHNE Symbol und OHNE Fokus
+ *      b. Datei oeffnen, Caret in createUser: jetzt gibt es einen Fokus
+ *      c. "@createuser explain this function": Karten, Antwort, Zitate
+ *      d. "@create": Kandidatenliste, einer wird geklickt, Frage laeuft weiter
+ *      e. ein Name, den es wirklich nicht gibt, bei vorhandenem Fokus
+ *      f. Kopfzeile beim Scrollen, Hoehe per Tastatur, Hoehe per Maus
+ *      g. Escape, Schliessen-Knopf, Wiederoeffnen, clear
+ *      h. die drei Stellen, an denen das lokale Modell benannt wird
+ *      i. Reload: die gezogene Hoehe steht noch
+ *   7. abraeumen, Restprozesse zaehlen (auch den eigenen Sidecar), JSON, Bilder
+ *
+ * Das Ganze laeuft unter dem Netz-Deny-Gate (npm run smoke:w7c).

+/*
+ * W8-Smoke: feste Plaetze statt gestapelter Fenster, und der Leser zieht die
+ * Grenzen.
+ *
+ * ## Der Befund, den dieser Lauf beweist
+ *
+ * Nutzerbefund vom 2026-08-29 mit Screenshot: Flow-Erklaerer, Antwort-Panel und
+ * Schrittkarte standen gleichzeitig offen, ueberlagerten sich, und alle drei
+ * waren angeschnitten. Der Massstab dazu kam vom Nutzer selbst: "es soll
+ * intuitiv sein wie Apple und nicht verwirren; die Oberflaeche ist
+ * hauptsaechlich dafuer da, dass Devs Code besser verstehen".
+ *
+ * Gemessen wird darum nicht, dass es die Reiter GIBT, sondern dass der Zustand,
+ * den der Befund beschreibt, nicht mehr herstellbar ist: der Lauf oeffnet
+ * nacheinander alles, was frueher uebereinander lag, und zaehlt jedes Mal, wie
+ * viele Inhalte gleichzeitig im Baum stehen.
+ *
+ * ## Warum dieser Lauf ohne Modell auskommt
+ *
+ * Fuer AC5 braucht er einen Chat-Verlauf. Ein Zug entsteht auch OHNE laufendes
+ * Modell: eine Frage bei ausgeschaltetem Modell landet als abgelehnter Zug im
+ * Verlauf, mit ihrem Grund darin. Das ist keine Notloesung, sondern genau die
+ * Ehrlichkeitsregel, die W5a fuer diesen Fall gebaut hat, und sie ist hier
+ * dienlich: der Lauf belegt den Zustand des Chats, ohne den Sidecar des Nutzers
+ * auf 4141 anzufassen und ohne ein eigenes Modell zu starten.
+ *
+ * ## Was hier NICHT gemessen wird und warum
+ *
+ * Der Zug mit der Maus wird gefahren und nicht nachgestellt: `mouse.down`,
+ * `mouse.move`, `mouse.up` auf dem Griff. Was dabei zaehlt, ist nicht die Zahl
+ * im Griff, sondern das RECHTECK der Zone daneben: eine Zahl, die sich aendert,
+ * ohne dass sich etwas bewegt, waere ein Griff, der nur so tut.
+ *
+ * ## Ablauf
+ *
+ *   1. `npm run build`
+ *   2. isoliertes HOME, eigenes Rendezvous-Verzeichnis (CBM_RUNTIME_DIR)
+ *   3. fixtures/atlas-sample indizieren (nur gelesen)
+ *   4. C-Server auf einem freien Port >= 4440, dist/ auf einem zweiten
+ *   5. Chromium ohne Aussenwelt
+ *      a. Ruhezustand: eingeklappter Erklaeren-Bereich, Zonen ohne Ueberlagerung
+ *      b. jeder leere Reiter sagt, warum er leer ist
+ *      c. Zustand aufbauen: Frage, Fuehrung, Flow-Schritte
+ *      d. Reiterwechsel: immer genau ein Inhalt, und keiner verliert etwas
+ *      e. Escape, Verlauf, clear: was W7c fuer den Chat erkaempft hat
+ *      f. die vier Griffe: Maus, Tastatur, Doppelklick, Anschlaege
+ *      g. Reload: die gezogenen Masse stehen noch
+ *      h. der Weg zurueck, ueber die Zeile und ueber das Menue
+ *      i. die beiden Extremlagen, jeweils mit Lesbarkeitsmessung
+ *   6. abraeumen, Restprozesse zaehlen, JSON, drei Bilder im Ruhezustand
+ *
+ * Das Ganze laeuft unter dem Netz-Deny-Gate (npm run smoke:w8).

+/*
+ * W8b-Smoke: Knoepfe sagen, was sie tun, und nichts legt sich mehr ungefragt
+ * darueber.
+ *
+ * ## Warum dieser Lauf existiert
+ *
+ * Vier Nutzerbefunde vom 2026-08-29 Nachmittag, mit Screenshots bei 100 und bei
+ * 67 Prozent Zoom. Sie haengen alle an derselben Wurzel: die Oberflaeche
+ * erklaerte sich ueber Zeichen und ueber Tooltips, die sie weder platzieren
+ * noch messen konnte.
+ *
+ * Der erste Befund ist der, der diesen Lauf noetig macht. Der Tooltip "76
+ * nodes, 178 edges from /api/layout" lag ueber dem Detail-Regler und ueber den
+ * Chips Logic, Calls, Data. Der Nutzer dazu: "ich hab damals schon in Auftrag
+ * gegeben, dass sich Dinge ueberlappen, was uncool ist." Er hat recht, und die
+ * Ursache ist gemessen: das waren native `title`-Tooltips, 78 im Produktivcode.
+ * Der Browser zeichnet sie AUSSERHALB des Dokuments, unter dem Mauszeiger, ohne
+ * Rechteck. Deshalb hat kein Beweislauf dieses Projekts sie je gesehen: die
+ * Ueberlagerungsmessung liest `getBoundingClientRect`, und ein nativer Tooltip
+ * hat keine. Es gab 78 Flaechen, die sich ueber beliebigen Inhalt legen
+ * konnten, und null Messung darauf.
+ *
+ * Also misst dieser Lauf zwei Dinge, und das zweite ist erst moeglich, weil das
+ * erste stimmt:
+ *
+ *  1. **Kein nativer Tooltip erklaert mehr etwas.** Gezaehlt wird nicht "hat
+ *     ein `title`", sondern "hat einen `title`, der mehr sagt als der sichtbare
+ *     Text": ein Attribut, das nur wiederholt, was danebensteht, ist ein
+ *     anderer Fehler und faellt ersatzlos weg. Gezaehlt wird an JEDEM Halt der
+ *     Strecke, nicht einmal am Anfang.
+ *  2. **Jeder eigene Tooltip wird EINZELN geoeffnet und vermessen.** Ein Lauf,
+ *     der einmal hinsieht und "keine Ueberlagerung" meldet, haette ueber die
+ *     anderen siebenundsiebzig nichts gesagt. Geoeffnet wird mit dem Zeiger UND
+ *     mit der Tastatur, denn ein Tooltip, den nur die Maus oeffnet, ist keiner.
+ *
+ * ## Was hier nicht behauptet, sondern gemessen wird
+ *
+ * Drei Zahlen dieses Artefakts sind MESSUNGEN und keine Zusicherungen, und sie
+ * duerfen deshalb auch anders ausfallen, ohne dass der Lauf rot wird:
+ *
+ *  - `unresolvedCallsReported`: ob der Index an dieser Stelle ueberhaupt
+ *    unaufgeloeste Aufrufe meldet. Das Vorgehen aus AC6.2 haengt an der
+ *    Antwort: meldet er sie, steht die Zahl unter dem Bild; meldet er sie
+ *    nicht, bleibt genau ein allgemeiner Satz. Was die Zahl NICHT sehen kann,
+ *    steht unter `unresolvedCallsMethod` im Artefakt, und das gehoert dazu:
+ *    ein Aufruf, den der Index ganz ohne qualifizierten Namen meldet, faellt
+ *    schon im Walk heraus (src/provider/closure.ts filtert ihn) und ist an
+ *    dieser Stelle nicht mehr zaehlbar.
+ *  - `honestyBlockChars` und `honestyBlockParagraphs`: was unter dem Diagramm
+ *    wirklich steht, aus dem gerenderten Baum gelesen und nicht aus den
+ *    Konstanten gerechnet.
+ *  - `handleHitAreaPx`: das kleinste Mass aller vier Griffe quer zu ihrer
+ *    Achse, aus `getBoundingClientRect` und nicht aus der CSS-Datei.
+ *
+ * ## Der Zoom, und warum er ein groesseres Fenster ist
+ *
+ * Chromium kann seinen Zoom in einem headless-Kontext nicht wie ein Nutzer
+ * stellen. Was 67 Prozent Zoom fuer das LAYOUT bedeutet, ist aber exakt
+ * beschreibbar: bei gleichem Fenster wird der CSS-Ansichtsbereich um den
+ * Kehrwert groesser. 1680 mal 1050 bei 100 Prozent sind 2507 mal 1567 bei 67.
+ * Genau das stellt dieser Lauf ein, und die Rechnung steht im Artefakt.
+ *
+ * ## Ablauf
+ *
+ *   1. `npm run build`
+ *   2. isoliertes HOME, eigenes Rendezvous-Verzeichnis (CBM_RUNTIME_DIR)
+ *   3. fixtures/atlas-sample indizieren (die Fixture wird nur gelesen)
+ *   4. C-Server auf einem freien Port >= 4540, dist/ auf einem zweiten
+ *   5. Chromium ohne Aussenwelt, plus Route-Sperre
+ *      a. Ruhezustand: keine nativen Tooltips, die Griffe, die Beispiele
+ *      b. jeden Tooltip einzeln oeffnen und messen, mit Zeiger und Tastatur
+ *      c. die Schalter: Wort statt Zeichen, und der Name folgt der Ansicht
+ *      d. der Twin voll, der Graph offen, 100 Prozent, kein Ziehen
+ *      e. der Flow: der Block kurz, die Grenze am Bild, der Schrittsatz da
+ *      f. der Chat: Tiefe aendern, Angebot, neuer Zug, alter Zug unveraendert
+ *      g. der Kopf des Chats bei 100 und bei 67 Prozent
+ *      h. die Frage: Escape, und eine Datei oeffnen
+ *   6. abraeumen, Restprozesse zaehlen, JSON und vier Bilder im Ruhezustand
+ *
+ * Das Ganze laeuft unter dem Netz-Deny-Gate (npm run smoke:w8b).
+ *
+ * ## Ports
+ *
+ * Ab 4540. 4390 und 4391 gehoeren der Vorschau des Nutzers, 4141 seinem
+ * Modell-Sidecar, 4360 und 4400 den Eval-Laeufen, 4440 und 4460 den Laeufen von
+ * W8 und W9. Dieser Lauf fasst keinen davon an.

+ * W8c-Smoke: der Pseudocode-Block fuehrt mit dem, was der Code nicht zeigt.
+ *
+ * ## Warum dieser Lauf existiert
+ *
+ * Nutzerfrage vom 2026-08-29 zum Screenshot mit orderService.ts: "ist der
+ * Pseudocode AI generated oder mechanisch, und ist er hilfreich?" Die Herkunft
+ * war schnell belegt (mechanisch: im Bild steht LOCAL_MODEL off, und
+ * src/pseudocode/ kennt das Modell nur in refine.ts, das der Leser selbst
+ * anstoesst). Die zweite Haelfte der Frage war die teure: neben einer
+ * 18-Zeilen-Funktion standen zwei Zeilen, "1. call validateId" und "2. call
+ * query", waehrend der Code daneben try/catch, `rows.find`, den fruehen
+ * Ausstieg, den Objektbau und ein `console.error` zeigte. Der Block war eine
+ * Zusammenfassung, die weniger enthielt als das Original.
+ *
+ * Also misst dieser Lauf vier Dinge an einem echten Server, und keines davon
+ * kann ein Unit-Test messen:
+ *
+ *  1. **Der Block fuehrt mit dem Fund.** Gemessen an der Lage der Kaesten im
+ *     gerenderten Baum (`getBoundingClientRect`), nicht an der Reihenfolge im
+ *     Quelltext: was oben steht, steht oben, auch wenn CSS etwas anderes
+ *     wollte. Dazu die Gegenprobe zur Laengenschwelle: derselbe Aufbau bei
+ *     einer Funktion mit zwei Schritten wie bei einer mit sechs, und in beiden
+ *     Faellen ist jede Zeile des Dokuments auch im DOM.
+ *  2. **Jeder Schritt traegt sein Ziel.** Gezaehlt wird nicht "hat einen
+ *     Ortstext", sondern "ist ein Knopf, dessen Klick den Reader an genau die
+ *     Datei und Zeile des AUFGERUFENEN Symbols bringt". Und wo der Index keine
+ *     Stelle kennt, steht das an der Zeile.
+ *  3. **Was hinter dem Aufruf liegt, kostet keine Anfrage.** Die Zaehler des
+ *     Proxys werden vor dem Umschalten auf den Block und danach gelesen; die
+ *     Differenz muss null sein. Was dabei WIRKLICH vorlag, steht als
+ *     `enrichmentAvailable.usable` im Artefakt, und was nicht vorliegt, als
+ *     `missing` samt Grund.
+ *  4. **Kein Meta-Rauschen mehr.** Die Zeichen ueber den Block selbst werden
+ *     an der Flaeche gemessen (was sichtbar dasteht) und die verschobenen
+ *     Saetze am Griff des Panels. Beide Zahlen stehen im Artefakt, damit die
+ *     Kuerzung nachrechenbar ist statt behauptet.
+ *
+ * ## Was hier gemessen und nicht behauptet wird
+ *
+ * `metaCharsBefore` ist die Summe der Saetze ueber den Block selbst, die bis
+ * W8c auf der Flaeche standen: die Deckungszeile, die Namen ohne Deckung und
+ * die Herkunftsnotiz. Sie sind unveraendert dieselben Zeichenketten; W8c hat
+ * sie hinter das Fragezeichen geraeumt und keinen Buchstaben an ihnen
+ * geaendert. Der Lauf liest ihre Laenge am Griff des laufenden Panels
+ * (`metaMovedChars`) und die sichtbare Laenge am gerenderten Kasten, und
+ * rechnet daraus beide Werte. So ist der Ausgangswert eine Messung an dem, was
+ * das Produkt heute wirklich haelt, und keine Erinnerung an einen alten Stand.
+ *
+ * ## Ablauf
+ *
+ *   1. `npm run build`
+ *   2. isoliertes HOME, eigenes Rendezvous-Verzeichnis (CBM_RUNTIME_DIR)
+ *   3. fixtures/atlas-sample indizieren (die Fixture wird nur gelesen)
+ *   4. C-Server auf einem freien Port >= 4560, dist/ auf einem zweiten
+ *   5. Chromium ohne Aussenwelt, plus Route-Sperre
+ *      a. getOrder: der kurze Fall aus dem Nutzerbild
+ *      b. der Block: Reihenfolge, Kopf, Ziele, was dahinter liegt, Meta
+ *      c. ein Ziel anklicken: der Reader steht auf dem Aufgerufenen
+ *      d. createUser: der lange Fall, derselbe Aufbau
+ *   6. abraeumen, Restprozesse zaehlen, JSON und zwei Bilder im Ruhezustand
+ *
+ * Das Ganze laeuft unter dem Netz-Deny-Gate (npm run smoke:w8c).
+ *
+ * ## Ports
+ *
+ * Ab 4560. 4390 und 4391 gehoeren der Vorschau des Nutzers, 4141 seinem
+ * Modell-Sidecar, 4360 und 4400 den Eval-Laeufen, 4440, 4460 und 4540 den
+ * Laeufen von W8, W9 und W8b. Dieser Lauf fasst keinen davon an.

+/*
+ * W9-Smoke: die Kanten zeigen, was sie sind, die Legende zaehlt, was da ist,
+ * der Filter nimmt eine Art aus dem Bild, und die Hierarchie kennt mehr als
+ * Aufrufe.
+ *
+ * Martins Befund vom 2026-08-29: "Man sieht kaum verschiedenartige Kanten im
+ * Graph. Das sollte ja schon mit drin sein." Er hat recht, und die Ursache ist
+ * gemessen: /api/layout liefert fuer fixtures/atlas-sample zwoelf Kantenarten,
+ * gezeichnet wurden sie mit einer Deckkraft zwischen 0.04 und 0.25, und bei
+ * diesen Werten sind zwoelf Farben ein gleichmaessiger Schleier.
+ *
+ * ## Warum dieser Lauf Pixel liest und nicht Absichten
+ *
+ * Die Zusicherung dieses Zyklus ist eine ueber ein BILD. Ein Unit-Test kann
+ * zeigen, dass die Deckkraft-Kurve die Zahlen liefert, die im Kopf von
+ * EdgeLines.tsx stehen; er kann nicht zeigen, dass ein Leser danach zwoelf
+ * Farben sieht. Also wird hier die gerenderte Szene ausgelesen.
+ *
+ * Gemessen wird mit einer Differenz und nicht mit einer Farbsuche, und das ist
+ * der eine Kunstgriff dieses Laufs:
+ *
+ *   1. Ein Bild der Szene, wie sie dasteht (die Grundlage).
+ *   2. Fuer jede Kantenart: dieselbe Szene, diese eine Art abgeschaltet.
+ *   3. Was zwischen beiden Bildern an Licht FEHLT, ist genau das Licht, das
+ *      diese Art beigetragen hat. Seine Richtung im Farbraum ist die Farbe, in
+ *      der diese Art wirklich gezeichnet wurde.
+ *
+ * Der Unterschied zu "such alle Pixel in der Farbe X" ist kein technischer: die
+ * Suche findet auch Mischungen und Sterne, die zufaellig so aussehen, und sie
+ * beweist nie, dass ein Pixel VON dieser Kante kommt. Die Differenz beweist
+ * genau das, weil zwischen den beiden Bildern nichts anderes veraendert wurde.
+ * Der Filter ist damit nicht nur die Sache, die geprueft wird, sondern auch das
+ * Messinstrument.
+ *
+ * Zwei Schwellen gehoeren dazu und stehen beide im Artefakt:
+ *
+ *  - `colorDistanceThreshold` (40): ab diesem Abstand gelten zwei gemessene
+ *    Farben als verschieden. Verglichen wird euklidisch in RGB, nachdem beide
+ *    auf den gleichen Maximalkanal gebracht wurden; sonst wuerde eine dunkler
+ *    gezeichnete Kante als eigene Farbe zaehlen. Der kleinste Abstand zwischen
+ *    zwei Tabellenfarben, die in diesem Fixture zusammen im Bild stehen, ist
+ *    so gerechnet 57.6 (CALLS gegen den Vorgabeton), der zweitkleinste 67.8.
+ *    40 liegt darunter und ueber dem, was die Messung selbst streut.
+ *  - `colorMatchThreshold` (25): ab diesem Abstand gilt ein Pixel als "zeigt
+ *    diese Art". Enger als die erste, weil hier eine Verwechslung teurer ist:
+ *    ein einziges Mischpixel, das zufaellig in die Naehe faellt, wuerde die
+ *    Zusicherung "die Art ist aus dem Bild verschwunden" scheitern lassen,
+ *    obwohl sie stimmt.
+ *
+ * ## Was die Kamera macht, waehrend gemessen wird
+ *
+ * Nichts, und das ist eine Bedingung der Messung. Die Szene dreht sich nach 60
+ * Sekunden ohne Zutun von selbst weiter (IdleAutoRotate), und zwei Bilder aus
+ * verschiedenen Kamerapositionen sind nicht vergleichbar. Vor jeder Aufnahme
+ * geht darum ein Radereignis mit Weg null an den Canvas: es stellt die Uhr
+ * zurueck, ohne die Kamera zu bewegen (getZoomScale(0) ist 1). Bewiesen wird
+ * das nicht behauptet: am Ende wird die Grundlage noch einmal aufgenommen und
+ * gegen die erste gehalten (`sceneDriftMeanAbs`, muss praktisch null sein).
+ *
+ * ## Was auf den Beweisbildern steht
+ *
+ * Der Ruhezustand, und nichts sonst. Bis W9-1 scrollte dieser Lauf vor jeder
+ * Aufnahme die Legende zu den Kantenarten, weil sie hinter drei Absaetzen
+ * Fliesstext lagen. Auf den Bildern stand danach oben und unten je ein
+ * angeschnittener Satzrest, und ein Bild, das einen Zustand zeigt, den ein
+ * Leser nie zu sehen bekommt, beweist ueber die Oberflaeche nichts. Vor jeder
+ * Aufnahme geht jetzt jeder Bereich an den Anfang; dass er dort steht, wird
+ * gemessen und steht als `screenshotsAtRest` samt der Lage jedes Bereichs im
+ * Artefakt. Die Arten stehen dafuer in der Legende oben (galaxy-legend.ts).
+ *
+ * ## Ablauf
+ *
+ *   1. `npm run build`
+ *   2. isoliertes HOME, eigenes Rendezvous-Verzeichnis (CBM_RUNTIME_DIR)
+ *   3. fixtures/atlas-sample indizieren (die Fixture wird nur gelesen)
+ *   4. C-Server auf einem freien Port >= 4460, dist/ auf einem zweiten
+ *   5. Chromium ohne Aussenwelt, plus Route-Sperre
+ *   6a. /api/layout selbst holen und die Kantenarten zaehlen
+ *   6b. Legende aufklappen: Zeilen gegen die gezaehlten Arten halten
+ *   6c. Grundlage aufnehmen, dann Art fuer Art abschalten und die Differenz
+ *       messen: welche Farbe hat diese Art im Bild wirklich
+ *   6d. Eine Art bleibt aus: Zeile noch da, gedimmt, Kopf sagt die Zahl
+ *   6e. Einstieg waehlen (createUser), Hierarchie: Walk-Kanten und die
+ *       Beziehungen, die der Index dazu kennt, beide zaehlbar und filterbar
+ *   6f. Spalten unveraendert, mit und ohne die zusaetzlichen Kanten
+ *   7. abraeumen, Restprozesse zaehlen, JSON und drei Bilder schreiben
+ *
+ * Das Ganze laeuft unter dem Netz-Deny-Gate (npm run smoke:w9).
+ *
+ * ## Ports
+ *
+ * Ab 4460. 4390 und 4391 gehoeren der Vorschau des Nutzers, 4141 seinem
+ * Modell-Sidecar, 4360 und 4400 den Eval-Laeufen. Dieser Lauf fasst keinen
+ * davon an.

+/*
+ * Das Stil-Gate: lange Striche, Attribution, hartkodierte Chrome-Strings.
+ *
+ *   node tools/style-gate.mjs [--out verification/w6/stylegate.json]
+ *
+ * Drei Fragen an alles, was in diesem Repository landet, und alle drei sind an
+ * einem gruenen Testlauf nicht zu sehen.
+ *
+ * ## 1. Lange Striche
+ *
+ * U+2013 und U+2014 sind in diesem Projekt verboten (PLAN.md Abschnitt 12).
+ * Die eine erlaubte Ausnahme ist ein WOERTLICHES Zitat: ein Beweislauf, der
+ * aufschreibt, was ein Server geantwortet hat, darf die Antwort nicht
+ * umschreiben, nur weil ein Strich darin steht. Ein umgeschriebenes Zitat waere
+ * ein Beweis ueber einen Text, den es nicht gab.
+ *
+ * Die Ausnahme gilt darum nur unter `verification/`, nur in einer JSON-Datei,
+ * und jede einzelne Fundstelle wird mit Datei, Zeile und Grund im Ergebnis
+ * aufgezaehlt. Eine Ausnahme, die man nicht nachlesen kann, ist keine Ausnahme,
+ * sondern eine Luecke.
+ *
+ * ## 2. Attribution
+ *
+ * Kein Werkzeug und kein Modell wird in diesem Repository als Urheber genannt.
+ * Der Scan sucht darum ZWEI Dinge, und der Unterschied zwischen ihnen ist der
+ * ganze Punkt:
+ *
+ *  - **Urheberschafts-Muster**: eine Mitautoren-Zeile, eine Erzeugt-mit-Zeile,
+ *    eine Erwaehnung mit Klammeraffen, eine Mailadresse der Herstellerdomain
+ *    oder ein "written by" mit dem Namen dahinter. Das ist eine Attribution.
+ *    Davon darf es null geben, ohne jede Ausnahme.
+ *  - **Der blosse Name**, ohne Ansehen der Gross-/Kleinschreibung. Davon gibt
+ *    es in diesem Repository eine Handvoll, und alle stehen in dem Satz, der
+ *    Attribution VERBIETET: die Regel selbst in den beiden Regeldateien und die
+ *    Zusicherung im Abnahmetest, der diese Zahl prueft. Ein Verbot, das seinen
+ *    eigenen Gegenstand nicht nennen darf, waere unformulierbar.
+ *
+ * Deshalb steht im Ergebnis `attributionHits` fuer den Namen AUSSERHALB dieser
+ * Verbotssaetze, und jede ausgenommene Fundstelle steht mit Datei, Zeile und
+ * Wortlaut daneben. Eine Zeile ist nur dann ausgenommen, wenn sie erstens kein
+ * Urheberschafts-Muster traegt und zweitens erkennbar von der Regel handelt
+ * (ein Verneinungswort, das Wort Attribution, oder der Name der Regeldatei in
+ * derselben Zeile). Damit kann die Ausnahme keine echte Attribution
+ * verstecken: eine Signaturzeile traegt keines dieser Worte.
+ *
+ * Die gesuchten Namen und die gesuchten Zeichen stehen nicht in dieser Datei,
+ * sondern in tools/lib/forbidden-names.mjs, und dort als Zeichencodes. Der
+ * Grund steht im Kopf jener Datei: ein Waechter, der seinen eigenen Suchbegriff
+ * ausschreibt, findet sich selbst, und die uebliche Antwort darauf (die eigene
+ * Datei von der Pruefung ausnehmen) macht genau die eine Datei blind, in der
+ * sich etwas verstecken koennte. Was gesucht wird, steht aufgeloest im
+ * Ergebnis, unter `namesWatched`.
+ *
+ * ## 3. Hartkodierte Chrome-Strings
+ *
+ * Dieselbe Zahl, die auch der Unit-Test misst (src/i18n/messages.test.ts). Sie
+ * steht hier mit, weil der Abnahmetest sie in stylegate.json liest und weil ein
+ * Gate, das drei Stilfragen stellt, nicht die vierte an eine andere Datei
+ * abgeben sollte. Die Regeln stehen in tools/lib/chrome-scan.mjs.
+ *
+ * ## Welche Dateien gelesen werden
+ *
+ * `git ls-files` PLUS die noch nicht aufgenommenen Dateien, die nicht ignoriert
+ * sind (`git ls-files --others --exclude-standard`). Nur die verfolgten zu
+ * lesen hiesse, genau die neuen Dateien eines Zyklus auszulassen, also die
+ * einzigen, die eine neue Verletzung enthalten koennten. Binaerdateien werden
+ * an ihrem NUL-Byte erkannt und uebergangen.

+ * **Der Lade-Smoke laeuft mit dem KLEINSTEN Modell und auf einem Testport.**
+ * Das Ziel ist "diese Runtime laedt ein GGUF und antwortet", nicht "dieses
+ * Modell ist gut". Das kleinste Modell macht daraus einen Lauf von Sekunden.
+ * Der Port liegt bei 4300 aufwaerts und nicht auf 4141: der Produktport gehoert
+ * dem Sidecar, den ein Leser gerade laufen haben koennte, und ein Pruefskript,
+ * das ihm den Port wegnimmt, waere ein Pruefskript, das man nicht laufen lassen
+ * kann, waehrend man arbeitet.
+ *
+ * **`--version` allein reicht nicht.** Es beweist, dass das Binary startet und
+ * seine dylibs findet, aber nichts ueber Metal, den GGUF-Leser oder den
+ * HTTP-Server. Deshalb wird zusaetzlich ein Modell geladen und `/health` bis
+ * `{"status":"ok"}` gefragt. Erst beides zusammen ist `llamaServerRuns`.
+ *
+ * **Der Prozess wird gezaehlt, nicht gehofft.** Am Ende steht, ob auf dem
+ * Testport noch jemand lauscht. Ein Verifikationslauf, der einen 700-MB-Prozess

+# Optional llama.cpp runtime provenance
+
+The binaries are not committed. This document records the source and build procedure
+for the optional Apple Silicon sidecar used by the GGUF evaluation. Browser inference
+uses the separately documented ONNX runtime.
+
+## Source and build
+
+- Source: https://github.com/ggml-org/llama.cpp
+- Recorded tag: **b10675**, commit `90c26fc`
+- Built from source on 2026-08-28 for Darwin arm64
+- Reported binary version: `0.3.0-dev (build 1, commit 90c26fc)`; the build lacked
+  the Git metadata used for the numeric build counter
+
+```sh
+cmake -B build -DGGML_METAL=ON -DGGML_RPC=OFF -DCMAKE_BUILD_TYPE=Release
+cmake --build build --config Release --target llama-server
+```
+
+Metal enables local GPU inference. Disabling GGML RPC omits the remote-compute backend.
+The local scripts `llm/start.sh` and `llm/stop.sh` manage the sidecar at
+`127.0.0.1:4141`. The recorded build includes `llama-server` and nine dynamic libraries.
+
+Copy the executable and libraries identified by `otool -L`, then replace their build
+paths and sign the modified files locally:
+
+```sh
+install_name_tool -rpath <build-directory>/bin @executable_path vendor/llama/llama-server
+install_name_tool -rpath <build-directory>/bin @loader_path vendor/llama/<library>
+codesign --force --sign - vendor/llama/<file>
+```
+
+These operations change the bytes. Independent rebuilds need not reproduce the
+recorded hashes; compare source revision and build options as well.
+
+## External dependencies
+
+The recorded build loads Homebrew OpenSSL from these absolute paths; the libraries
+are not copied into this directory:
+
+```text
+/opt/homebrew/opt/openssl@3/lib/libssl.3.dylib
+/opt/homebrew/opt/openssl@3/lib/libcrypto.3.dylib
+```
+
+It therefore requires that OpenSSL installation. Other dependencies are system
+libraries, including CoreFoundation, Security, libc++ and libSystem.
+
+## Recorded SHA-256 values
+
+These identify the locally patched and signed files, not the original build output.
+Symlink aliases are omitted.

Those compact responses begin with rows_refs/rows_ref_rule; therefore the empty-symbol UI is not evidence that the backend index lacks those symbols. A frontend format/parsing incompatibility is a concrete suspect; no repair or separate parser reproduction was performed in this audit.",
+    "Both servers accepted since:HEAD and returned actual detect_changes results: changed_total234, changed_returned0, output-budget truncation, impacted_total252, impacted_shown93. Thus the pending Since HEAD UI frames do NOT establish endpoint failure or absence of existing diff-analysis capability. The default Working tree UI still visibly failed, and the new selection widget does not integrate these change-set results."

Edit this draft before sharing it.\n\nRecorded paths: 2 (files and directories; not a file-coverage denominator).\nIgnored file records stored: 1; total reported: 1.\nIncomplete list: the server cut the parse_partial list: 1 recorded, fewer listed\nIncomplete list: the server cut the not_indexed list: 0 folders and 1 files recorded, fewer listed\nDaemon caveat: Best-effort signal only. No recorded issue does not prove graph or source completeness; read flagged source and qualify claims when metadata is changed or unavailable.\n\n- partial.c (file): Partial parse\n  Recorded reason: Source lines: 2-2\n  Evidence source: check_index_coverage.scope:.\n  Next check: Read the reported source ranges; verify missing symbols before relying on graph paths.\n\n- excluded.c (file): Excluded by index rules\n  Recorded reason: cbmignore\n  Evidence source: check_index_coverage.scope:.\n  Next check: Review the recorded exclusion rule; open the source directly or adjust that rule before reindexing.",

Gezaehlt werden die Knoten ausserhalb und der kleinste verbleibende Rand in Pixeln. Die AUSRICHTUNG wird unabhaengig geprueft: dieser Lauf rechnet die Hauptachsen der geladenen Positionen selbst (Jacobi, principalAxes in dieser Datei) und haelt die duennste Achse gegen die gemeldete Blickrichtung. Dass die Messung ueberhaupt etwas sieht, wird vorher gezeigt: die Kamera wird mit Zug und Rad verdreht, bis Knoten aus dem Bild fallen.",

Every line is a rule over facts and not a fact, which is why they all wear the derived marker.No rule fired against this symbol.

This is part of the answer and not a footnote: an architect who cannot see the edge of the index will read a silence as a finding.The purpose of this symbol: The purpose of this symbol is derived from indexed callers, not read directly.What this symbol does outside its own process: What this symbol does outside its own process is unknown because the analyzer does not record this for this language.The tests covering this symbol: The tests covering this symbol is derived from indexed callers, not read directly.This engine records no test relation for TypeScript at all, so \"what checks it\" is answered by looking at callers that live in test files, and never by the index saying so.Raised error types are recorded; the places they are caught are not. A short error list is therefore not evidence that the failure is contained.Routes for TypeScript are read out of the source text by CodeAtlas, not reported by the engine, so an entry point the engine did not mark can still exist.Two calls to the same target inside one body are recorded once, with the last site. A count of call sites is therefore a count of targets and not of calls.This server hands observed calls to trace and flow answers, not to the twin, so this section stays empty.

This is part of the answer and not a footnote: an architect who cannot see the edge of the index will read a silence as a finding.The purpose of this symbol: The purpose of this symbol is derived from indexed callers, not read directly.What this symbol does outside its own process: What this symbol does outside its own process is unknown because the analyzer does not record this for this language.The tests covering this symbol: The tests covering this symbol is derived from indexed callers, not read directly.This engine records no test relation for TypeScript at all, so \"what checks it\" is answered by looking at callers that live in test files, and never by the index saying so.Raised error types are recorded; the places they are caught are not. A short error list is therefore not evidence that the failure is contained.Routes for TypeScript are read out of the source text by CodeAtlas, not reported by the engine, so an entry point the engine did not mark can still exist.Two calls to the same target inside one body are recorded once, with the last site. A count of call sites is therefore a count of targets and not of calls.This server hands observed calls to trace and flow answers, not to the twin, so this section stays empty.

+ * recover what the raw parse LOST. When an expanded def d and a raw def r sit
+ * at the same site (same label, name and start line, cbm_raw_def_same_site)
+ * but carry different QNs, the two parses scoped ONE definition differently,
+ * and adopting d minted a second node for it. One decision, in the rescue:
+ *
+ *   - By default the RAW copy wins and d is not adopted. The expanded parse is
+ *     no better judge of scope: it nests utilcode.h's classes inside
+ *     CUnorderedArrayWithAllocator, puts rapidjson reader.h's StackStream and
+ *     NumberStream specializations at file scope instead of inside
+ *     GenericReader, and picks one of the `namespace SVR` / `namespace WKS`
+ *     branches of coreclr gc's #ifdef. What the expanded pass gave d's QN
+ *     (call and usage scopes, resolved targets, members only it saw) moves to
+ *     r's QN (cbm_requalify_result).
+ *   - EXCEPT when r's enclosing scope exists only because of a raw ERROR
+ *     region the expanded parse resolved (cbm_misnested_raw_twin). A
+ *     macro-generated body (`struct s { mixed_members };`, the kernel's
+ *     lib/tests/randstruct_kunit.c) keeps the raw field list from closing, and
+ *     every later struct of the file nests inside it; the expanded parse gets
+ *     them flat. Then d REPLACES r, and whatever carried r's QN or sat under it
+ *     (Fields, nested definitions, call/usage scopes, resolved member
+ *     references) moves to d's QN (cbm_requalify_result). Every condition is
+ *     required:
+ *       - d lies in a raw ERROR region;
+ *       - r's QN is d's scope plus at least one more segment: the raw parse
+ *         nested the definition DEEPER under the same outer scope;
+ *       - r's immediate raw parent p is a raw type definition whose span holds
+ *         r, and the expanded parse has p too (same label, name and start
+ *         line) but closes it BEFORE d starts;
+ *       - a raw ERROR region lies between p's opening and d: the raw parse
+ *         lost p's closing brace there;
+ *       - the original text closes p's braces on exactly the line where the
+ *         expanded parse closes p (comments, literals and directive lines
+ *         skipped): the source itself ends p there, so no expanded error
+ *         closed p early (a local expanded error, such as an attribute macro

+ *     language (mermaid; plantuml, puml, uml; dot, graphviz; d2): the Diagram
+ *     hangs under the Section the block is written in (the last heading above

+ *   - a Mermaid file (.mmd, .mermaid): one Diagram, under the file.
+ *
+ * Qualified names: the parent's (a Section's, else the file's module QN) +
+ * "#diagram-<k>", k counting the diagrams of that parent from 1; an element's
+ * is the diagram's + "." + its id (dots and blanks as `_`).
+ *
+ * A Diagram's docstring is the text its elements and arrows carry (their
+ * labels), which is what a reader of the diagram reads; its properties hold
+ * the format and the diagram kind. An element's name is its label (its id
+ * when it has none); its properties hold the id and the element kind. An
+ * element named only by an arrow is an element too.
+ *
+ * Formats (one parser each, line by line, no grammar): Mermaid flowchart and
+ * graph, sequenceDiagram, classDiagram, erDiagram, stateDiagram, C4 (Context,
+ * Container, Component, Dynamic, Deployment) and architecture-beta. Every
+ * other Mermaid kind (gantt, pie, journey, mindmap, ...) is a Diagram without
+ * elements.

+ * doc_adoc.c — AsciiDoc documents in the graph (the extraction half;
+ * src/pipeline/doc_links_adoc.c resolves), and the Antora scope blob.
+ *
+ * AsciiDoc has no grammar here: like a PDF, the file is read directly. Each
+ * heading (`= Title` .. `====== Title`, or `#` .. `######`) outside a
+ * delimited block becomes a Section (name the title, the text up to the next
+ * heading as its docstring, its lines up to the next heading); text before
+ * the first heading belongs to the file. Delimited blocks (`----` listing,
+ * `....` literal, `////` comment, `++++` passthrough, `====` example, `****`
+ * sidebar, `____` quote, `|===` table, ``` fences) open and close on the same
+ * delimiter line (the field test's H8 rules).
+ *
+ * References become tokens whose `raw` is the reference as written, then
+ * TAB-separated fields:
+ *   include     include::target[attrs] (Asciidoctor's preprocessor directive:
+ *               read in every block but a comment block; `\include::` is
+ *               escaped): written, target with the page's attributes
+ *               substituted (references the page does not define stay as
+ *               `{name}` for the component's), tags (`tag=` / `tags=`),
+ *               lines (`lines=`)
+ *   attribute   an attribute reference `{name}` in the text: written, name,
+ *               the page's value as written and as the page expands it (both
+ *               "" when the page does not define it).
+ *               Antora components define their API links as attributes
+ *               (`{Assertions}` -> a javadoc page): the resolver reads them.
+ *   code_path,  a monospace span (`x`, ``x``, `+x+`) naming a path or a
+ *   code_name   qualified name (the Markdown code-span classifier); raw is
+ *               the span's text
+ * Page attributes (`:name: value`, `:name!:` / `:!name:` to unset) apply from
+ * their line on, in document order.
+ *
+ * The Antora scope (cbm_doclink_antora_scan_scope): an antora.yml's component
+ * name, its asciidoc attributes and its collector scans; an
+ * antora-playbook*.yml's asciidoc attributes. Read as text, never run.

+ * doc_adr.c — architecture decision records: detection, facts, supersedes.
+ *
+ * A Markdown file that is an ADR gets one more definition: label "ADR", name
+ * its canonical id ("ADR-12"; another prefix as written, "DEC-5"; a dated
+ * record without a number keeps its file stem), qualified name
+ * "<module>.__adr__", and the record's facts as node properties (adr_id,
+ * title, status, date, deciders, superseded_by). Its File DEFINES it like any
+ * definition, its sections link to code like any document's (doclink_md.c),
+ * and its own "supersedes X" / "replaces X" statements become tokens of the
+ * `supersedes` family, whose source is the ADR node: the resolver turns them
+ * into SUPERSEDES edges between ADR nodes.
+ *
+ * "Superseded by Y" is written in the OLD record, about another file: an edge
+ * from Y's node would be owned by a file whose text does not hold it, so it
+ * stays a fact of this record (status superseded, superseded_by) and the link
+ * itself is a MENTIONS edge of the status section.
+ *
+ * Detection (the field tests' rules, 99.2 % on 379 files): a file in a
+ * conventional ADR directory (adr, adrs, decisions, decision-records, ...)
+ * whose name carries an id or whose text has ADR structure; any `adr-NNN-*`
+ * file; a numbered or dated file with ADR structure. Never README, index or
+ * template files without an id, never test fixtures. Structure: a status, and
+ * a context, decision, consequences, decision outcome or considered options
+ * section. ADR-log configuration files (.adr-dir, log4brains) are not read:
+ * per-file detection, a pure function of the path and the text.

+ * doc_pdf.c — PDF documents in the graph.
+ *
+ * A PDF's text layer (pdf/) becomes one Section per page: name "page N", the
+ * page's text as its docstring, so search finds what a page says. The code a
+ * page names becomes doc-link tokens for the resolver (doc_links_pdf.c):
+ * STRUCTURAL mentions only -- paths ("src/auth/handler.go", "./x/y",
+ * "Pool.sol") and qualified names ("pkg.Type.method", "a::b", "x->y"). Bare
+ * identifiers never become tokens (field test E6c: bare names stay
+ * suggestions).
+ *
+ * The scanner is the field-tested one (E6 idents.py), ported with CPython's
+ * semantics: NFKC per code point plus canonical composition, the re module's
+ * leftmost-first matching, str predicates from the same Unicode tables
+ * (pdf/pdf_unicode.c). A mention split across two lines ("src/auth/" /
+ * "handler.go", "Handler::" / "run") is proposed as a JOIN token that lists
+ * the line-local tokens it would replace; the resolver keeps the join only
+ * when it resolves EXACT or UNIQUE, and the fragments stand otherwise.
+ *
+ * Hygiene from the field test, applied here where the text decides it: R1 a
+ * PDF under a test or fixture directory gives no tokens; R3 a mention written
+ * as a keyword argument ("(x, foo.bar=1)") is no reference.

+/*
+ * doclink.h — doc-comment references, extraction half.
+ *
+ * A definition's complete doc comment (extract_defs.c stores it whole) can
+ * name other code: C# `<see cref="..."/>`, Java `{@link ...}`, Rust intra-doc
+ * links, and so on. Extraction only FINDS those references; whether one names
+ * a graph node is decided later, per file, by the pipeline's resolver
+ * (src/pipeline/doc_links.c), which turns them into MENTIONS edges or
+ * doc_link_unresolved rows.
+ *
+ * A language leg plugs in at two places of this half, and nowhere else:
+ *   - its link families: lines of CBM_DOCLINK_FAMILY_LIST below (enum value,
+ *     name, ship gate);
+ *   - one row of the language table in doclink.c:
+ *       parse_doc       one documented definition's doc text -> CBMDocLink
+ *                       tokens
+ *       scan_scope      the file's doc-link SCOPE: a language-tagged text blob
+ *                       with what other files' resolution needs from this file
+ *                       (C#: namespaces, usings, type and member
+ *                       declarations). A pure function of the file's bytes,
+ *                       persisted with the file's LSP surface, and so
+ *                       identical on full and incremental runs. Optional.
+ *       scope_tag,      the blob's tag line and its persisted form (line
+ *       portable_scope  numbers dropped). Optional.
+ *       loose_docs      after the definitions and the file's own doc: the
+ *                       file's other doc comments, which the graph keeps no
+ *                       node for. What it pushes with the file stand-in
+ *                       belongs to the file (C: a prototype's doc); it may push
+ *                       with a definition of the file instead (PHP: a
+ *                       property's doc belongs to its class). Optional.
+ *       scan_file       instead of parse_doc, for a DOCUMENT language whose
+ *                       text is the documentation (Markdown): one pass over
+ *                       the file's bytes pushes every reference, with the
+ *                       section it is written in as its source. Optional.
+ *     State a language's hooks need between their calls for one file lives in
+ *     ctx->doclink_state (cbm.h), never in a static or thread-local.
+ * A language without a row produces no tokens and no scope. The resolving
+ * half's hooks are a cbm_doclink_resolver_t (src/pipeline/doc_links.h).

+ * doclink_c.c — C doc-comment references (Doxygen) and the C doc-link scope.
+ *
+ * Files. Only .c and .h files: a .h is parsed as C++, which does not change
+ * that; other C++ and Objective-C sources are not part of this leg.
+ *
+ * Docs. The four Doxygen comment styles: blocks opening with slash-star-star
+ * or slash-star-bang, and runs of lines opening with three slashes or with
+ * slash-slash-bang (a `<` after the opener marks a member's trailing doc). A
+ * definition's stored doc goes through cbm_doclink_c_parse_doc. Every other
+ * Doxygen block of the file outside function bodies (a prototype's doc in a
+ * header, which the graph keeps no node for; a group's text) goes through
+ * cbm_doclink_c_loose_docs, and its references belong to the file.
+ *
+ * Tokens:
+ *   - `@ref name` or `\ref name`, an optional quoted label after it: family
+ *     doxygen_ref;
+ *   - the names listed after `@see`, `\see`, `@sa` or `\sa` (the paragraph up
+ *     to an empty line or the next command at the start of a line) that have
+ *     the shape of a symbol: `name`, `name()`, `::name`: family see. An
+ *     explicit @ref inside such a paragraph is a doxygen_ref token.
+ * Text inside \code, \verbatim, \dot, \msc or \startuml blocks, a Markdown
+ * fence or a code span holds none, nor does the word after \c, \p, \a, \b, \e
+ * or \em. A URL is the core's href family.
+ *
+ * Scope blob, one record per line after the tag line "c1" (tab-separated):
+ *   D kind link name qn parent  a definition the graph has a node for:
+ *                        kind f (function), v (variable), t (type: typedef,
+ *                        struct, union or enum), e (enum constant), r (a
+ *                        struct or union field), m (object-like macro), M
+ *                        (function-like macro); link x (visible in every file:
+ *                        external linkage, or a type, constant or macro of a
+ *                        header) or s (this file only: static, a type,
+ *                        constant or macro of a .c file, a field); qn the
+ *                        node's qualified name; parent the enum of a constant
+ *                        or the struct of a field ("-" for none)
+ *   A name               a Doxygen page, group, anchor or section the file's

+ * cannot serve: once it loses the thread inside a string it lexes code as
+ * string content. So the braces are scanned here, with the lexical grammar a
+ * brace scanner needs -- comments, character and string literals in all
+ * their forms, interpolation holes, preprocessor branches. On the 30,881

+ * doclink_go.c — Go doc links and the Go doc-link scope.
+ *
+ * Tokens. A Go doc comment has no link markup of its own kind: a doc link is
+ * bracketed text that go/doc/comment decides to treat as one. This file ports
+ * the half of that decision that needs only the comment (go/ast
+ * CommentGroup.Text, then go/doc/comment unindent, parseSpans, link
+ * definitions, parseLinkedText's bracket scan with its border rule, and the
+ * name shape of docLink/splitDocName). What it emits are CANDIDATES:
+ *   [Name]  [Recv.Name]  [pkg]  [pkg.Name]  [pkg.Recv.Name]
+ * each optionally with a leading `*`, where pkg is an identifier or an import
+ * path. The other half of the decision (does the package declare the name,
+ * does the file import the package) needs the whole package and is the
+ * resolver's (src/pipeline/doc_links_go.c): a candidate that fails it is plain
+ * text, exactly as go/doc renders it, and leaves neither an edge nor a row.
+ * A `[Text]` with a link definition `[Text]: scheme://...` in the same comment
+ * is a URL: one `href` token per use.
+ *
+ * Never a link: code blocks (indented lines), `# ` headings (go/doc keeps
+ * heading text plain), the link-definition paragraphs themselves, and a
+ * bracket pair that touches a letter or digit (`map[K]V`, `a[i]`).
+ *
+ * Scope blob (first line "go1", then one record per line, tab-separated,
+ * sorted; only exported names are recorded, a doc link can name nothing else):
+ *   P  name  flags          package clause; flags: i build-ignored file
+ *                           (`//go:build ignore`), c another build-constraint
+ *                           line, e parse errors in the file, - none
+ *   I  local  path          import; local `-` when not renamed (dot and blank
+ *                           imports are no qualifiers and are left out); path
+ *                           `?` when it is none this scan can record
+ *   F  name  w              function
+ *   M  recv  name  w        method (recv `?` when the receiver type is not a
+ *                           plain name)
+ *   T  name  kind  alias  w type; kind s struct, i interface, a alias, o other;
+ *                           alias: the target of `type X = Y` / `= pkg.Y`
+ *   V  name  w              variable or constant
+ *   f  type  name  node     struct field (node 0: embedded, or not the first
+ *                           name of its declaration)
+ *   m  type  name           interface method
+ *   g  first  last  names   type parameters (','-joined) of the declaration
+ *                           that spans the lines first..last. Only in the
+ *                           blob of a fresh extraction; the persisted blob
+ *                           drops these lines and so carries no line number
+ *                           at all.
+ *   G  path                 go.mod: the module path
+ * w says who keeps the node <dir>.<name>. A function, a type and a value of
+ * one name all claim it, and within a file the declaration on the LAST line
+ * keeps it (cbm_gbuf_upsert_node). A method claims nothing: its node is
+ * receiver-qualified (<dir>.<Recv>.<Method>, #1913), and its w is `-`. w is 1 for
+ * that declaration, 0 for the others of that name, x when two of them start
+ * on that last line, and - for a value the extractor gives no node at all
+ * (it gives one to the first name of a constant spec and of a parenthesis-
+ * free `var`).
+ * The records are sorted and w is the only order-dependent field: the blob
+ * does not change when declarations merely move, and it does change when a
+ * move hands a node to another declaration.

+ * doclink_md.c — Markdown references to code: the extraction half.
+ *
+ * In a Markdown document the text IS the documentation, so its references are
+ * not taken from a definition's doc comment: one pass over the file's bytes
+ * finds the explicit ones and gives each to the section it is written in --
+ * the Section definition (a heading) at or above its line, or the file itself
+ * for text before the first heading (CBM_DOCLINK_FLAG_FILE). Families
+ * (doclink.h):
+ *
+ *   link       the destination of an inline link `[text](dest)` or of a link
+ *              reference definition `[label]: dest`, when it is no URL, no
+ *              in-page anchor and no image
+ *   path       a bare path in prose: a slash and a file extension
+ *   code_path  a code span, or an HTML <code> span, whose text is a path, a
+ *              file name or a directory, with an optional line range
+ *              (`#L3-L9`, `:3-9`) or member (`path::Name`)
+ *
+ * Never scanned: YAML front matter, fenced code blocks, HTML comments, the
+ * import/export lines of MDX. Never a reference here: a URL, an in-page
+ * anchor, an image, a name without a path (a bare name is at most a
+ * suggestion, never an edge).
+ *
+ * Cost. Each scan of a line is linear in the line, or n log n where it sorts.
+ * The searches that could otherwise rescan a stretch of the line for every
+ * candidate (the end of a link destination, the closing parenthesis, the
+ * closing backticks of a code span) are answered from position lists of the
+ * few bytes they look for, by binary search. The lists grow with the number
+ * of those bytes, not with the line, and are released at the end of the
+ * file. A list that cannot grow marks the file's doc links failed, so the
+ * resolving half fails the layer instead of publishing a graph that silently
+ * misses references.
+ *
+ * The rules are those the documentation field tests measured (H0): explicit
+ * paths and links bind EXACTLY, at 99 % precision on 53 repositories.

+ * doclink_perl.c — Perl POD `L<>` references and the Perl doc-link scope.
+ *
+ * Tokens. A sub's stored doc is every POD section whose =headN / =item heading
+ * names it (extract_defs.c), verbatim and joined by a blank line. Its L<>
+ * formatting codes are the references, read the way perlpodspec and
+ * Pod::Simple read them:
+ *   - a paragraph is a run of non-blank lines. Codes are looked for in ordinary
+ *     paragraphs and in the text of =headN and =item. A verbatim paragraph
+ *     (first byte a space or tab), a =for paragraph and a =begin .. =end
+ *     region of a format without a leading colon are data and hold no code;
+ *   - a code is a capital letter and `<`. `X<< text >>` (two or more brackets
+ *     and whitespace) ends at whitespace and as many `>`. Codes nest; an L
+ *     inside an L is not a link (perlpodspec: links must not nest);
+ *   - an L<> whose target (what follows `text|`) matches `\w+:[^:\s]\S*` is a
+ *     URL: the core's href family. Every other one is a pod_L token whose raw
+ *     text is the code's content as written, white space squeezed. A code the
+ *     paragraph ends before, and one longer than CBM_DOCLINK_PERL_RAW_MAX,
+ *     keeps its opening `L<` in the raw text: nothing parses that, so the
+ *     resolver records it as unparseable.
+ * A doc that does not start with a POD command is a `#` comment and has no
+ * formatting codes at all.
+ *
+ * Lines. The stored doc carries no position, and several sections can be
+ * joined in it, so every section of the file is found again here (the same
+ * paragraph, command and section rules as extract_defs.c) and the doc is
+ * matched against them byte for byte: a reference then gets the source line it
+ * is written on. A part of a doc that matches no section keeps the line the
+ * core passed (the definition's). That needs the file's sections once per
+ * file, and parse_doc is called per definition: the call for the file's first
+ * documented definition harvests the whole file, the later ones return.
+ *
+ * Scope blob (one record per line, tab-separated, first line "perl1"; no line
+ * numbers, so it is persisted as it is):
+ *   E               the tree has a parse error: which package a sub belongs to
+ *                   is not trusted

+ * doc. Its lines lose their leading white space, one `*` and one space. A
+ * reference is
+ *   - `@see Ref` at the start of a tag line, a description may follow;
+ *   - `{@see Ref}` or `{@see Ref description}` anywhere on a line;
+ * both family `see`. The reference is the text up to white space (or the
+ * closing brace), sentence punctuation at its end dropped. A URL is the core's
+ * href family. Text in a code span (backticks on one line) or in a fenced
+ * code block holds no reference. @link, @uses and the other tags are not
+ * harvested.
+ *
+ * Scope blob, one record per line after the tag line "php1" (tab-separated):
+ *   N blk name first last  a namespace block, numbered from 0 in file order,
+ *                          its name ("-": the global namespace) and lines; a

+ *                          its one block is number 0
+ *   U blk kind alias name  a use import of block blk: kind c (a class or a
+ *                          namespace), f (a function), k (a constant); the
+ *                          alias as written, the name without its leading
+ *                          backslash
+ *   T kind fqn flags first last  a class (c), interface (i), trait (t) or enum
+ *                          (e) declared at the top level of a block, its fully
+ *                          qualified name and lines; flags `d` when the file
+ *                          declares another type or function of the same name
+ *                          (the graph keeps one node for both), else `-`
+ *   B rel fqn              a supertype of the T record before it: rel e
+ *                          (extends), i (implements), t (a used trait), the
+ *                          name qualified as PHP resolves it in this file
+ *   K kind name            a member of that type: m method, p property (no
+ *                          `$`; promoted constructor parameters too), c
+ *                          constant, e enum case
+ *   F fqn flags            a function declared at the top level of a block;
+ *                          flags as for T
+ * "At the top level" includes the branches of a top-level conditional
+ * (`if (!function_exists('f')) { function f() {} }`), never a function body.
+ * Doc blocks on properties, class constants and enum cases, which have no
+ * node, go through cbm_doclink_php_loose_docs: their references belong to
+ * the type around them.
+ *
+ * The persisted blob (cbm_doclink_php_portable_scope) drops the lines of N
+ * and T and the U records: other files read names only, and every name a
+ * supertype record holds is already qualified.

+ * doclink_rs.c — Rust intra-doc links and the Rust doc-link scope.
+ *
+ * Tokens. Only what rustdoc itself documents is read: `///` (not `////`),
+ * a block opened by slash-star-star (not by three stars), `//!` and the bang
+ * block. The Markdown is read the way pulldown-cmark reads it for rustdoc:
+ * fenced and indented code blocks, HTML blocks, code spans, inline HTML and
+ * autolinks hold no links; link reference definitions are collected first;
+ * inline `[text](dest)`, full `[text][label]`, collapsed `[label][]` and
+ * shortcut `[label]` links are found, images, footnotes and task markers are
+ * not links. A link is a reference when rustdoc's `preprocess_link` keeps it.
+ * Families:
+ *   intra_doc  the destination is written at the link: `[text](path)`, and
+ *              `[path]`, `[path][]`, `[text][path]` whose label has no
+ *              definition
+ *   link_def   the destination comes from a link reference definition
+ *   href       (the core's) an inline or defined destination that is a URL
+ * A relative file destination and a page anchor are not harvested.
+ *
+ * Scope blob: one record per line, tab-separated, first line "rs1". Records
+ * marked (fresh) exist only in the blob of the extraction itself and are
+ * dropped by the persisted form, which also zeroes every line number:
+ *   B                                 the tree has a parse error, or holds
+ *                                     something this scan cannot represent:
+ *                                     a name the file's modules do not show
+ *                                     may still be declared there

+ * 't' for `#[cfg(test)]` / `#[test]`, 'e' for `#[macro_export]`, 'c' for a
+ * `mod` whose file cannot be told from the tree (a conditional path
+ * attribute; an inline module with a path attribute, which moves the files of
+ * the `mod x;` inside it).
+ * node: '!' when the definition has no graph node of its own, else a label
+ * code (S Struct, E Enum, C Class, I Interface, T Type, F Function,
+ * V Variable, M Method, D Field) followed by '=' when the node's qualified
+ * name is <module>.<name>, or by ':' and the part after "<module>.".
+ *
+ * Every item is matched to its definition in ctx->result->defs, so a node's
+ * qualified name is the extractor's own (cfg suffixes, impl self-type text).
+ * The graph keeps one node per qualified name: a definition owns it only when
+ * it is the survivor among the file's definitions of that name (largest start
+ * line, then name, then label -- cbm_gbuf_upsert_node's rule).
+ *
+ * Everything is derived from the tree and the definitions extracted from it,
+ * so the blob is a pure function of the file's bytes.

+ * doclink_rst.c — reStructuredText documents: their sections, and the code
+ * their text names (the extraction half; src/pipeline/doc_links_rst.c
+ * resolves).
+ *
+ * Structure: the field test's line model (H3 RstDoc) with CPython's str
+ * semantics -- tabs expanded to 8 columns, str.strip / str.split whitespace
+ * and re's \s and \w from the Unicode tables the PDF scanner uses. Every line
+ * gets a kind: title, adornment, prose, directive head / argument / option,
+ * literal block (after `::` or in a code directive), comment, hyperlink
+ * target. Titles are found by adornment style (over+under or under only; the
+ * level is the style's first appearance). Each title becomes a Section
+ * definition: name the title, docstring the text up to the next title, lines
+ * from its title to the line before the next one. Text before the first title
+ * belongs to the file.
+ *
+ * References become tokens whose `raw` is the reference AS WRITTEN followed by
+ * TAB-separated fields the resolver reads (a doc_link_unresolved row shows the
+ * written form first; whitespace inside a field is collapsed, so no field
+ * holds a TAB):
+ *   role            :py:class:`x`, :func:`~a.b`, :c:type:`t`, :source:`p`

+ *                   written, directive, signature, module, class, C namespace,
+ *                   the Python full name in its class ("" when Sphinx's
+ *                   signature grammar does not read it)

+ * registry's export table ONCE, after the func/type indexes are finalized
+ * (every probe below is a hashed lookup or a binary search) and before the
+ * seal. Per module it computes the namespace its imports bind: a re-export
+ * resolves its target through further re-exports (chains); a star copies the
+ * source module's namespace, restricted to its literal `__all__` when it has
+ * one and otherwise to names without a leading `_`; the module's own
+ * definitions are never replaced. Modules are visited in sorted order and
+ * records in source order; a module reached again while its own namespace is
+ * being computed (an import cycle) contributes what it has so far, so every
+ * cycle ends with the same answer on every run. PY_NS_MAX_DEPTH bounds only

 - **mojo** (added 2026-07-01): vendored from [lsh/tree-sitter-mojo](https://github.com/lsh/tree-sitter-mojo) @ `33193a99afe6` — MIT, ABI 15. Helix tracks `lsh/tree-sitter-mojo` as its Mojo grammar source, but the Helix-pinned commit (`3d7c53b8038f`) no longer resolves in the upstream repository after a force-push, so this vendor uses current upstream `main` rather than the stale registry SHA. Security review covered only the vendored C surface (`parser.c`, `scanner.c`, `tree_sitter/*.h`) plus upstream license/provenance metadata; no package manager hooks, workflow files, prompt/agent instruction files, or generated lockfiles were vendored.
 - **arkts** (added 2026-08-26): **first-party derivative** — a fork of [tree-sitter/tree-sitter-typescript](https://github.com/tree-sitter/tree-sitter-typescript)'s `typescript` dialect pinned @ `75b3874edb2d` (v0.23.2, the same commit our vendored typescript/tsx come from), on the tree-sitter-javascript base @ `3a837b6f3658` (v0.23.1, the version upstream's own package-lock pins), extended with ArkTS/ArkUI syntax (`@Component struct` declarations, UI-DSL trailing-closure calls with post-block attribute chains, decorated function declarations, `import lazy`, `@Extend`/`@Styles` leading-dot attribute chains, anonymous `stateStyles` style blocks). Grammar source + corpus tests live in `tools/tree-sitter-arkts/`; regenerate with `npx tree-sitter-cli@0.25.10 generate` (ABI 15). **External scanner:** `scanner.c` is a symbol-rename trampoline; `_common_scanner.h` is byte-identical (same SHA-256) to the reviewed `typescript/_common_scanner.h` already shipped. **LICENSE:** tree-sitter-typescript's MIT text **verbatim and byte-identical** (© 2017 Max Brunsfeld) — which is what MIT requires of a derivative work, and what lets the provenance audit byte-verify it against upstream rather than take a note on trust. The fork is registered in the audit's `FORKS` map. Our own copyright for the ArkTS additions, and the tree-sitter-javascript attribution (© 2014 Max Brunsfeld), live with the SOURCE in `tools/tree-sitter-arkts/grammar.js` and in `THIRD_PARTY.md`, which is what ships in the release archives.
 - **javascript + tsx** (forked 2026-09-25, #1736): **self-maintained forks** of the pins we already vendored — [tree-sitter/tree-sitter-javascript](https://github.com/tree-sitter/tree-sitter-javascript) @ `58404d8cf191` and [tree-sitter/tree-sitter-typescript](https://github.com/tree-sitter/tree-sitter-typescript)'s `tsx` dialect @ `75b3874edb2d` (javascript base @ `3a837b6f3658`, the version upstream's package-lock pins, as for arkts). **Why:** upstream accepts a `&` inside a JSX string only before a space/digit or as a complete character reference, and never inside JSX text, so a plain URL query (`href="…?a=1&b=2"`, Google Fonts `&display=swap`) or `<p>Tom & Jerry</p>` produced an ERROR node — a `parse_partial` flag, plus false USAGE edges from identifiers the error recovery pulled out of the URL (on vercel/next.js `examples/`: 45 of 92 flagged files, 115 false cross-example USAGE edges). **The change** is one patch, `tools/tree-sitter-javascript/patches/jsx-lone-ampersand.patch`, applied to both javascript bases: a lone `&` that does not begin a complete `html_character_reference` is a one-character token (lexical precedence -1, so `&amp;`/`&#38;` still lex as references) aliased to the EXISTING `string_fragment` / `jsx_text` nodes, and the string-fragment regexes stop before a `&` that directly precedes the closing quote. Node types are unchanged (same type/named set; `node-types.json` only gains an empty `fields` map on those two entries). Without the patch both directories regenerate upstream exactly (javascript: byte-identical `parser.c` apart from the generator-version comment; tsx: identical state/symbol counts, ABI 14 → 15 from the newer CLI). **External scanners** are unchanged: `javascript/scanner.c` and `tsx/scanner.c` + `_common_scanner.h` stay the reviewed upstream bytes. Regenerate with `npx tree-sitter-cli@0.25.10 generate` in `tools/tree-sitter-{javascript,tsx}/` (ABI 15) and copy `src/parser.c` (tsx: also `src/tree_sitter/*.h`) here. **On an upstream bump:** re-fetch the new pins, re-apply the patch, regenerate, re-run `test/corpus/jsx_ampersand.txt` — and drop the fork if upstream fixes it. **LICENSE:** upstream's MIT text byte-identical (registered in the audit's `FORKS` map); our copyright for the patch lives in the fork `grammar.js` headers and `THIRD_PARTY.md`.
+- **pascal** (forked 2026-09-25, #2211): **self-maintained fork** of the pin we already vendored — [Isopod/tree-sitter-pascal](https://github.com/Isopod/tree-sitter-pascal) @ `042119eca2e1` (full: `042119eca2e18a60e56317fb06ee3ba5c32cb447`, v0.10.2, upstream `master` HEAD at fork time). **Why:** upstream's `identifier` token is ASCII-only (`/[&]?[a-zA-Z_]+[0-9_a-zA-Z]*/`), so a Delphi identifier with non-ASCII letters — e.g. the Cyrillic member names of 1C's OLE API called through late-bound Variants — produced ERROR nodes and a `parse_partial` flag. **The change** is one patch, `tools/tree-sitter-pascal/patches/unicode-identifiers.patch`, touching only that token: `/[&]?[\p{L}_][\p{L}\p{M}\p{Nd}_]*/` (a Unicode letter or `_` first, then letters, combining marks, decimal digits or `_`). Keywords are still extracted from this `word` token, so `begin`/`end`/`procedure` lex as before (and `begin` glued to Cyrillic letters is one identifier). Node types are unchanged: `node-types.json` is identical to the unpatched regeneration, and versus upstream's 0.24-generated file it only gains the 0.25 generator's `"extra": true` markers. The `\p{}` classes compile to numeric code-point ranges, so the vendored `parser.c` stays **0 non-ASCII bytes**. **Fidelity:** upstream's `parser.c` carries no generator stamp (its package.json pins tree-sitter-cli ^0.24.5). Regenerating the UNPATCHED grammar with 0.25.10 gives the same symbol/token/field/production counts (only state minimisation differs, 4299 vs 2715 states) and parse trees byte-identical to upstream's shipped parser on upstream's 88 corpus cases and its three `examples/*.pas` (37,773 tree lines for `codetoolmanager.pas`); the patched parser (2715 states) gives the same identical trees on all of those inputs. Regenerate with `npx tree-sitter-cli@0.25.10 generate --abi 14` in `tools/tree-sitter-pascal/` (ABI 14, as the upstream pin, so the ABI tally is unchanged) and copy `src/parser.c` + `src/tree_sitter/parser.h` here (`parser.h` is byte-identical to the reviewed chialisp copy); no external scanner. **On an upstream bump:** re-fetch the pinned `grammar.js`, re-apply the patch, regenerate, re-run `test/corpus/unicode_identifiers.txt` plus upstream's corpus — and drop the fork if upstream accepts Unicode identifiers. **LICENSE:** upstream's MIT text byte-identical (registered in the audit's `FORKS` map); our copyright for the patch lives in the fork `grammar.js` header and `THIRD_PARTY.md`.
 - **plsql** (added 2026-08-27): vendored from [AndreasMaierDe/tree-sitter-plsql](https://github.com/AndreasMaierDe/tree-sitter-plsql) @ `28aebef209be` (full: `28aebef209be57169600e1aa41ca1431cc6c916f`, upstream tip; repo dormant since 2023-02) — MIT, ABI 14, **no external scanner** (`EXTERNAL_TOKEN_COUNT 0`). Not listed in nvim-treesitter/Helix (`community-niche`, an individual-maintained grammar); provenance verified directly against upstream (pin = `git ls-remote` HEAD; vendored `parser.c` byte-identical to the pinned clone apart from the include-quote local patch below; 0 non-ASCII bytes; 0 dangerous calls). Security review covered only the vendored C surface (`parser.c`, `tree_sitter/parser.h`) plus upstream license/provenance metadata; no package manager hooks, workflow files, prompt/agent instruction files, or generated lockfiles were vendored. Known upstream limitation: `CREATE TYPE ... AS OBJECT` currently yields ERROR nodes (pinned by `plsql_create_type_as_object_limitation` in `tests/test_extraction.c` + `tests/fixtures/plsql/create_type_as_object_limitation.tps`). Originally contributed as PR #1033 by Oğuz (@ouzsrcm); re-vendored from upstream per vendoring policy with the PR's language wiring distilled on top.
 
 - **chialisp** (added 2026-08-28): **first-party** — authored in this repository, not vendored from anywhere. Grammar source + corpus tests live in `tools/tree-sitter-chialisp/`; regenerate with `npx tree-sitter-cli@0.25.10 generate --abi 14` and copy `src/parser.c` + `src/tree_sitter/*.h` here. ABI 14, **no external scanner** (`EXTERNAL_TOKEN_COUNT 0`), 0 non-ASCII bytes. It is a deliberately GENERIC s-expression grammar (`source_file`/`list`/`symbol`/`string`/`number`/`hex`/`dot`/`comment`) modelling the clvm_tools reader rather than the Chialisp form vocabulary: `mod`/`defun`/`defconstant`/`include` are ordinary head symbols, and which lists are definitions is decided in `internal/cbm/extract_defs.c`, so a dialect that adds a form does not need a regenerated parser. Written because the only public grammar (`Quexington/tree-sitter-chialisp`) cannot parse the language: it required CRLF to terminate a comment (`/;.*\r\n/`) while real files are LF, rejected the `.` in `(include foo.clib)`, and accepted only a primitive after `(defconstant NAME …)` — each of which desynchronised the rest of the file. Acceptance gate: all five `chia-blockchain@main` reference files parse with **zero ERROR and zero MISSING nodes**. **LICENSE:** the project's own LICENSE, byte-identical to the repository root — no third-party copyright is carried, because there is no third party.

 | swift      | `swift/scanner.c`, `OP_SYMBOL_SUPPRESSOR` + `eat_operators` | `1UL <<` / `1 <<` → `1ULL <<` | UBSan: `1 << suppressor` shifts an `int` by up to `TOKEN_COUNT` bits, undefined once the index reaches 31, while the mask it feeds is `uint64_t`. `1UL << FAKE_TRY_BANG` is the same defect on Windows, where `unsigned long` is 32 bits and `FAKE_TRY_BANG` is 32; the CLANGARM64 leg runs UBSan in trap mode, so there it is an illegal instruction rather than a log line. Upstream already carries both changes: `fb63a7004f07` (2026-04-06, upstream #558) for `eat_operators`, `6ab8d1d74ebd` (2026-08-10) for the `OP_SYMBOL_SUPPRESSOR` entry. Our pin `8abb3e8b3325` (2026-03-20) predates both, so this is a backport rather than a local invention — a re-vendor past 2026-08-10 should delete this row, not re-apply it |

 The runtime set for your platform is downloaded automatically at install time. There is one composition per platform and the graph UI is always included — the former `CBM_VARIANT=ui` opt-in is obsolete.
 
+For testing, `CBM_DOWNLOAD_URL` overrides the download base URL (default `https://github.com/DeusData/codebase-memory-mcp/releases/download/v<version>`): the archive and `checksums.txt` are fetched from `<CBM_DOWNLOAD_URL>/<file>`. It must be `https://`, or plain `http://` to exactly `localhost`, `127.0.0.1`, or `[::1]` (optional port; no proxy, no redirects).

 There is one composition per platform: the graph UI ships in every build, so no variant selection is needed.
 
+For testing, `CBM_DOWNLOAD_URL` overrides the download base URL (default `https://github.com/DeusData/codebase-memory-mcp/releases/download/v<version>`): the archive and `checksums.txt` are fetched from `<CBM_DOWNLOAD_URL>/<file>`. It must be `https://`, or plain `http://` to exactly `localhost`, `127.0.0.1`, or `[::1]` (optional port; no proxy, no redirects).

-# WHAT WAS TRIED for (A) — each disproven by measurement, do not repeat:

-#     the floor is applied in cbm_thread_create for both the default and

-#     between 256 MiB and 1024 MiB -- a 4x stack increase changing nothing is
-#     what rules out "the stack is merely too small".
-#  3. MSAN_ORIGINS 2 -> 1 -> 0. Detection is identical at every level and 0
-#     gives the smallest frames; same thread, same address. Frame inflation is

+# red gate teaches everyone to ignore it and hides the findings the other

-# Instrumented frames are several times larger, so the byte budget is gone
-# before the depth counter trips. If that is right, the fix is a guard that
-# measures remaining stack rather than counted depth, and it would make these
-# suites pass under every sanitizer rather than papering over one lane.

-# WHY (A) AND (B) ARE EXCLUDED RATHER THAN LEFT RED: the lane is gating. A

+# The gap: the summary used to grep a failing suite's log for "FAIL" and then

+# legend. A Windows sanitizer job therefore went red with an empty "every
+# failure site" section and a legend, and the cause had to be found by reading
+# code. A trap-mode UBSan build (Windows on ARM) is worse still: it dies on an
+# illegal instruction and prints nothing at all, so the only evidence in the

+#!/usr/bin/env python3
+"""coverage-map.py — build the per-test coverage map of the C test runner: for
+every test, the set of functions it executed, children included. The test-impact
+engine uses it to narrow the suites whose tests cross a process boundary, where
+the call graph alone cannot say which test reaches which function.
+
+Input: the instrumented runner (make -f Makefile.cbm test-runner-cov). Run with
+CBM_TEST_COVERAGE_DIR it leaves, per suite, raw profiles named after the test
+(tests/test_main.c, "Per-test coverage profiles"):
+    <test>.parent.profraw     the runner inside the test
+    <test>.<pid>.profraw      one per child process of the test
+    <test>.<pid>.forked       an unaccounted forked child
+    _setup.<n>.profraw        the runner between tests
+    _setup.child.<pid>.profraw  children started between tests
+    _setup.child.<pid>.forked   unaccounted children started between tests
+
+Output directory:
+    functions.tsv   <id> TAB <source file> TAB <name>
+                    The file is where the function body stands, relative to the
+                    repository root, read from the coverage mapping of the
+                    runner itself (llvm-cov export). The profile only names the
+                    translation unit: a function of a unity build or a static
+                    inline of a header would otherwise carry the wrong file,
+                    and the engine joins the map to the graph by file and name.
+    tests.tsv       <suite>:<test> TAB <complete|incomplete> TAB <reason> TAB <ids>
+                    ids ascending, space separated. <suite>:* is what ran BETWEEN
+                    the tests of a suite (its setup); a change there concerns
+                    every test of the suite.
+    meta.json       commit, toolchain, and per suite: tests, incomplete tests,
+                    exit code, wall seconds
+
+A test is `incomplete` when its coverage cannot be trusted to be whole: a
+forked child left its marker, a profile is unreadable, the parent profile is
+missing, or the suite did not exit 0. An incomplete test must always be
+selected; the map never claims less than it knows.
+
+Raw profiles are about 7 MiB each, so every suite is reduced and deleted before
+the next one runs.
+
+Usage:
+    coverage-map.py --runner build/cov/test-runner --out DIR
+                    [--suite NAME ...] [--llvm-bin DIR] [--root DIR]
+                    [--keep-raw] [--timeout SECONDS]
+Exit status: 0 map written; 1 a suite failed or timed out (map still written,
+its tests incomplete); 2 usage or toolchain error.

+"""coverage-merge.py — the incremental coverage map of a main-branch push.
+
+Merges FRESH (coverage-map.py output for the suites the push re-ran, made with
+the new commit's instrumented runner, so its functions.tsv is the new image's
+complete function table) into PREVIOUS (the previous published map):
+
+  * a suite FRESH ran keeps FRESH's rows exactly;
+  * every other suite the new runner still lists is carried from PREVIOUS,
+    each row's function ids remapped by (source file, name) onto FRESH's
+    table; a function the new image no longer has drops out of the row, and a
+    row's status (an incomplete row stays incomplete) is never improved;
+  * a PREVIOUS suite the new runner no longer lists is dropped.
+
+The merged meta.json names --commit and recounts every suite, so the C reader
+(cbm_coverage_map_metadata_matches) checks it like a full map. When the map was
+observed is not decided here: the producer carries the oldest observation of
+the previous bundle forward, so an incremental map ages out unless a full
+refresh runs (the receipt's 7-day bound).
+
+Usage: coverage-merge.py --previous DIR --fresh DIR --suites FILE --commit SHA --out DIR

+# Every PR push of September 2026 (one pr.yml run each) with the tier the

+#   makefile-by-name  the analysis classified Makefile.cbm by its DIFF
+#                     (source registration / test flags -> no tier of its
+#                     own); a file list cannot show that, so the selector
+#                     treats every Makefile.cbm change as a build-flag
+#                     change: T5-core, full. Deliberately conservative.
+#   read-by-tests     README.md, docs/index.html, docs/llms.txt and
+#                     pkg/npm/README.md are read by a C test (test_cli), so
+#                     a change to one runs the test legs (T1-tests) where
+#                     the analysis, which saw docs only, assigned T0a-docs.

+"""predict.py — map a detect_changes impact set to the C test suites it can
+affect: the PR test-impact SHADOW (scripts/ci/test-impact-shadow.sh).
+Report-only; nothing here decides a merge.
+
+The mapping is the one the September 2026 test-impact replay measured
+(detect_changes at depth 15 plus rule fallbacks, "dcF@15"):
+  - impacted test FUNCTIONS (graph rows in tests/*.c) map to the suites that
+    RUN_TEST them, resolved in their own file first; a nested suite (RUN_SUITE
+    inside another) resolves to the registered suite that runs it; only suites
+    registered in tests/test_main.c count, perf suites excluded;
+  - a changed tests/*.c file always selects its whole suite;
+  - a changed fixture (tests/fixtures/<key>/...) selects the suites whose test
+    files name <key>; a changed grammar selects the grammar suites;
+  - run-all: the lane selector's full, a changed test header or
+    test-infrastructure file, a saturated or truncated impact set, or a C
+    change the graph was not asked about -> every suite.
+
+Usage: predict.py --root DIR --changed FILE --selection FILE [--detect FILE]

+"""Strict data-only parser for the observed LLVM 22.1.8 frontend proftext.
+
+parse_profile_text(bytes, ParseLimits, *, cancel=None, cancel_context=None)
+returns an immutable tuple of ProfileRecord(raw_name, function_hash, counters),
+ordered by unsigned raw-name bytes and then uint64 hash. Zero values survive.
+
+Each record is a nonempty name line, '# Func Hash:', uint64, '# Num Counters:',
+positive uint64, '# Counter Values:', exactly that many uint64 lines, and one
+mandatory blank line. All delimiters are LF. Decimals are canonical. Empty
+documents, CR/NUL, extra sections and duplicate name/hash tuples fail closed.
+Names remain opaque bytes: no normalization, decoding or comment processing.
+
+Four exact positive integer limits bound input bytes, records, total counter
+values and total name bytes. Errors derive from ProfileTextError; MemoryError
+and callback exceptions propagate without a partial result. A pure, prompt
+cancel(context) predicate must return bool. It is called at entry/final publish
+and within explicit loops at intervals of at most 4096 byte/element operations.
+Python allocation/resizing/deallocation and callbacks are not preemptible.
+
+Limits bound logical input and result items, not exact interpreter heap use.
+This module performs no I/O and makes no image, authentication or closure claim.

+ *
+ *   receipt.json                    this module; the bundle's authority
+ *   .codebase-memory/graph.db.zst   the commit's frozen graph (artifact.h)
+ *   .codebase-memory/artifact.json
+ *   coverage/functions.tsv          optional coverage map, format 1
+ *   coverage/tests.tsv
+ *   coverage/meta.json
+ *
+ * The receipt binds every part by SHA-256: the graph by the digest of the
+ * graph as an importer sees it (cbm_store_graph_digest of the imported
+ * database), the map by the exact bytes of its three files. A digest is
+ * content binding only; where a bundle came from is established by whoever

+ *
+ * A port of the measured reference (scratchpad tia3/replay4.py, seeding and
+ * header symbol propagation), rule for rule:
+ *   - a hunk with lines at head seeds the definitions it overlaps; a hunk of
+ *     comment lines only seeds nothing; a pure deletion seeds the definition
+ *     around the deletion point; a hunk that overlaps no definition seeds its
+ *     whole file;
+ *   - the names a `-` line declared and head no longer defines are looked up
+ *     by text: every definition whose lines mention one is a seed
+ *     (NAME_REFERENCE), and a mention outside any definition of a source file
+ *     seeds that file whole; a deleted file contributes every name it had;
+ *   - a header change names what it changes (declared names, overlapped
+ *     definitions), closes those names over the headers' macros (pastes
+ *     included), and seeds every definition that mentions one in a file
+ *     including the header; a line it cannot classify, or any preprocessor
+ *     conditional, makes the header "file level": every test file including it
+ *     runs its suites whole;
+ *   - a changed test case or suite body is reported as such, never seeded.
+ * Every approximation selects more tests, never fewer.

+ * doc_links.h — doc-comment references -> MENTIONS edges.
+ *
+ * Extraction (internal/cbm/doclink.h) leaves every documented definition's
+ * references in CBMFileResult.doc_links and every file's doc-link scope in
+ * CBMFileResult.doc_scope. This layer resolves them in the per-file resolve
+ * phase, beside CALLS:
+ *
+ *   cbm_doclinks_build         once per run, after the run's nodes exist: the
+ *                              per-language indexes over every file's scope
+ *                              (this run's results, plus the stored scopes of
+ *                              files an incremental run did not re-extract)
+ *   cbm_doclinks_resolve_file  per file, concurrently: MENTIONS edges into the
+ *                              caller's edge buffer, unresolved rows into the
+ *                              run's slot for that file
+ *   cbm_doclinks_take_rows     the run's unresolved rows, for publication into
+ *                              doc_link_unresolved
+ *
+ * Resolution is guess-free: a reference becomes an edge only when it names
+ * one entity EXACTLY (qualified name, doc ID, alias) or UNIQUELY at the first
+ * scope level of the language's own lookup rules. Everything else is a row
+ * with a reason. One MENTIONS edge per (documented definition, target):
+ * {"via":"doc_comment","syntax":..,"tier":..,"line":<first>,"count":n}.
+ *
+ * Ship gate: a link family (doclink.h) whose tier is below the audit's bar
+ * does not ship. Its references still resolve, but a resolved one is written
+ * as a row with reason below_bar_tier instead of an edge; an unresolved one
+ * keeps its own reason.
+ *
+ * Per-language hooks: a cbm_doclink_resolver_t (C#: doc_links_cs.c).

+ * field test's harvester measured (H8: includes 97.6-100 % resolved, ~100 %
+ * precise; javadoc attributes 320/320).
+ *
+ * Antora: a component is the directory of an antora.yml; its pages live under
+ * <component>/modules/<module>/pages. Its attributes and collector scans, and
+ * a playbook's attributes, come from the YAML scope blobs (doc_adoc.c), so an
+ * incremental run resolves as a full one.
+ *
+ * include::target[...]: references the page left are expanded from the
+ * component's attributes, then the playbook's. A resource ID
+ * ([[version@]component:]module:]family$path) names
+ * <component>/modules/<module>/<family dir>/<path>, or a file a collector scan
+ * contributes there; any other target is relative to the including file. Its
+ * `lines=` bind the innermost definition holding them; its `tag=` / `tags=`
+ * regions -- the included file's own `tag::x[]` .. `end::x[]` comments, read
+ * from that indexed file -- likewise; a tag the file does not have binds the
+ * file (the document stays a dependent of that file, so it re-resolves when
+ * the file changes, on an incremental run as on a full one).
+ *
+ * {attribute} references whose value is an Antora javadoc link
+ * ({javadoc-root}/<module>/<package path>/<Type>.html[#member]) bind the
+ * Java or Kotlin type (or its member) that the repository's main sources
+ * declare under that package path.
+ *
+ * Monospace spans: the Markdown resolver's code-span rules (doc_links_md.c).

+ * doc_links_c.c — resolving C doc references (doclink_c.c): Doxygen @ref and
+ * @see names, with the lookup Doxygen itself has, which knows no imports.
+ *
+ * A name (`name`, `name()`, `::name`) is looked up
+ *   1. among the Doxygen pages, groups, anchors and sections of the
+ *      repository's docs: such a name is no code entity (a graph gap), and
+ *      never binds to a symbol of the same name;
+ *   2. among the definitions of the documented file, static ones included;
+ *   3. among the definitions every file sees: external linkage, and the types,
+ *      enum constants and macros of headers. A static definition of another
+ *      file is not visible.
+ * A field of the documented file (`@ref field`) comes after its other
+ * definitions and before what every file sees. `Type::member` names a field
+ * of the struct or union Type, or a constant of the enum Type, Type found by
+ * the same levels.
+ * The first level with a candidate decides. Its candidates are counted by
+ * qualified name: a prototype and its definition, and the #if variants of
+ * one definition, are one node, the one the graph keeps for that name. A
+ * definition (function, variable, type, enum constant) wins over a macro of
+ * the same name; with `()` written, a function or function-like macro wins
+ * over the others. One candidate binds (exact in the documented file,
+ * unique elsewhere), several are ambiguous, none is missing; but a word of an
+ * @see paragraph that names nothing and is a plain lowercase word (no `_`,
+ * digit, capital, `()` or `::`) is prose, which Doxygen prints as text: no
+ * row. Test code binds only from test code.

+ * doc_links_cs.c — C# cref resolution for doc_links.h.
+ *
+ * The project-wide index is built from every C# file's doc-link scope and
+ * every MSBuild project file's (internal/cbm/doclink_cs.c). Nothing is read
+ * from the disk. Graph nodes are only looked up by qualified name, never by
+ * line, so the closure-repair route (whose unchanged nodes are line-less
+ * proxies) resolves exactly as a full build does.
+ *
+ * Assemblies. The index does not know which files a project compiles; it
+ * goes by where a file stands. A project is a directory that holds a
+ * *.csproj -- one whose SDK compiles something: a project file of the
+ * NoTargets or Traversal SDK only runs build steps, and is the project of no
+ * file. A file belongs to the nearest project at or above it. An
+ * assembly is named by its project file: projects whose project files have
+ * the same name are one assembly (a reference source beside its
+ * implementation, the flavours of one library). A directory that holds
+ * several project files is an assembly of its own: which of them a file
+ * there is compiled into is not known. A file no project file stands above
+ * is of a shared tree -- the largest directory around it with no project
+ * file in or below it. A shared tree belongs to no assembly: the projects
+ * that include its files compile them. (A repository without any project
+ * file is one tree.)
+ *
+ * Entities. A type entity is (scope, name, generic arity, owner): the scope
+ * is its namespace, or its outer type's entity, so `Outer.Inner` and
+ * `Outer<T>.Inner` are two types. The owner of a top-level type is its
+ * assembly: the declarations of one full name in one assembly are one type
+ * with several declarations (its parts, a stub beside the implementation,
+ * one per flavour), and declarations in two assemblies are two types, which
+ * see nothing of each other. The shared trees' declarations have no
+ * assembly. A complete declaration there is a type of its tree. The parts of
+ * a `partial` type there are one entity whatever tree they stand in, and
+ * they are parts of every assembly's type of that name whose implementation
+ * is itself declared partial: what a reference sees of a partial type is its
+ * own assembly's parts and the shared trees'. Seen without an assembly's own
+ * parts -- from a shared tree, or from an assembly that has none --, a name
+ * those parts declare is ambiguous: it is neither bound to what else has
+ * that name nor missing.
+ *
+ * Contracts. A declaration in a project directory named `ref` is a stub:
+ * `ref` is the .NET convention for reference-assembly sources. Inside one
+ * assembly the stub stands behind the implementation: the implementation's
+ * node binds, the stub's only where the implementation has none (its file
+ * did not parse, it lacks the member, or a parse error hides it). An
+ * assembly whose every declaration of a type is a stub holds only the
+ * contract, and the rule joins a contract to the one implementation it can
+ * belong to: the declaration of that full name and arity the shared trees
+ * hold, when they hold exactly one and no assembly holds another
+ * implementation of the name (entity_twins). The stub is then no second
+ * type; a binding that exists only through the join is never exact.
+ * Nothing is chosen between two implementations, two assemblies or two
+ * shared trees.
+ *
+ * What a reference sees of a name: its own assembly's type -- for a file of
+ * a shared tree, what its own tree declares. Else every shared tree's and
+ * every other assembly's type of that name alike: one binds, several are
+ * ambiguous. Which assemblies a project references is not known, so nothing
+ * chooses between two of them -- no stub, no nearer directory.
+ *
+ * Alternatives. Complete declarations of one type in two or more projects
+ * (the flavours of one assembly) are alternatives: the one of the
+ * referencing file's own project binds, and from anywhere else the
+ * reference is ambiguous. The same holds for one member declared in two or
+ * more projects or shared trees, and for the parts of a type in two or more
+ * shared trees. The parts of a partial type in one place are no
+ * alternatives: the type's node is the part's that stands nearest to the
+ * reference (a choice of presentation: every part is the type).
+ *
+ * Nodes. A declaration owns the node at <module>.<path> when it is the last
+ * declaration of that path in its file (the extractor keeps one node per
+ * qualified name and the last declaration wins, so `Foo` / `Foo<T>` in one
+ * file leave one of them without a node: a graph gap, never a fallback to
+ * the other). The same holds for members: overloads share one node; `Foo.X`
+ * and `Foo<T>.X` share one, and it belongs to the later declaration.
+ * Operators, indexers, events, delegates, implicit and primary constructors
+ * have no node at all: a reference to one that is declared is a graph gap.
+ *
+ * Lookup is the C# compiler's cref binding, and it guesses nothing: the first
+ * scope level that has the name decides, and more than one candidate there
+ * is ambiguous.
+ *   - a simple name: the documented method's type parameters; then for every
+ *     enclosing type, innermost first: its type parameters, its own nested
+ *     types and members; then for every enclosing namespace, innermost
+ *     first: the types and namespaces in it, then (where a namespace
+ *     declaration of the file stands) that declaration's aliases and after
+ *     them its usings. The file's own usings and the project's global ones
+ *     belong to the outermost level. A using of an inner namespace
+ *     declaration is therefore asked before an outer namespace
+ *   - a qualified name: its first segment is looked up as a simple name that
+ *     names a type or a namespace; every further segment is a member of what
+ *     the one before named. There is no second try from another level, and
+ *     no fully-qualified shortcut past a nearer namespace of that name
+ *   - inherited members are not looked up: the compiler does not consider
+ *     them in a cref, in a class or in an interface, by a simple name or
+ *     through the derived type's name. Such a reference is a row
+ *     (CS_BIND_INHERITED says what else it could be)
+ *   - arity: a name without type arguments is the arity-0 type. A generic
+ *     type of that name never stands in (no cross-arity fallback); type
+ *     arguments select the types and the generic methods of that arity. A
+ *     method name without type arguments takes methods of any arity, the
+ *     non-generic ones first
+ *   - the level that has the name decides also when a parameter list
+ *     follows: a written signature binds the overload of THAT level with
+ *     exactly these parameter types; a type variable matches by its position
+ *     only (`{K}` ... `(K)` against `<TKey>` ... `(TKey)`); only when no
+ *     overload matches does one with a parameter type nothing is known about
+ *     count, and several of those are ambiguous. Without a parameter list an
+ *     overload group is ambiguous
+ *   - constructors: a parameter list on a type's name (`Foo(int)`,
+ *     `Ns.Foo(int)`, `Outer.Inner(int)`), `Foo.Foo`, and `Foo(int)` written
+ *     inside a generic `Foo<T>`; a bare `Foo` is the type; no constructor is
+ *     inherited
+ *   - `using static` brings in a type's nested types and its static members,
+ *     extension methods excepted
+ *   - explicit interface implementations are not addressable by name
+ *   - visibility: product code never binds a test-only declaration
+ *     (test_only_target, no fallback), and a namespace that only test code
+ *     declares is no name in its scope; a test program does not bind another
+ *     program's global-namespace test type
+ *
+ * Reasons.
+ *   - external is structural: a name through a namespace the repository does
+ *     not declare (a using of one, a qualifier that is one, an open
+ *     hierarchy: a base outside the repository), a keyword alias the
+ *     repository does not declare, a project whose global usings could not
+ *     be evaluated. There is no list of well-known outside names; the one
+ *     namespace treated as never the repository's own is `System` with what
+ *     is under it (CS_STANDARD_ROOT)
+ *   - missing: a name every scope level was asked for, in declared
+ *     namespaces only; a name whose level has no overload with the written
+ *     parameters; an inherited member named through a derived type or by a
+ *     simple name (the compiler binds no such cref) when the hierarchy is
+ *     the repository's
+ *   - graph_gap: declared, and no node (see Nodes); a namespace; what the
+ *     parser could not place (a type whose members a parse error hides
+ *     answers a member it does not show with graph_gap; a name some file
+ *     declares without an establishable scope is a gap wherever it is
+ *     written)
+ *   - ambiguous: several candidates at the level that has the name; two
+ *     assemblies' (or two shared trees') types of one name; the flavours of
+ *     one type or member seen from outside their projects; a name that parts
+ *     of the type out of the reference's view declare; also an overload
+ *     group -- or one project's complete declarations of one type -- larger
+ *     than CS_MAX_OVERLOADS that would have to be compared, and a name more
+ *     than CS_MAX_FOREIGN assemblies declare. The index's log line
+ *     doc_links.cs.ambiguous counts the references by these causes
+ *   - unparseable: a reference longer than CS_REF_BUF, with more segments
+ *     than CS_MAX_SEGS or more parameters than CS_MAX_PARAMS
+ * No limit decides silently: every one of them ends in one of these rows.

+ * doc_links_go.c — Go doc-link resolution for doc_links.h.
+ *
+ * Extraction (internal/cbm/doclink_go.c) emits every bracketed text of a doc
+ * comment that go/doc/comment COULD take for a doc link. This file makes the
+ * rest of go/doc's decision, which needs the whole package, and then binds:
+ *
+ *   [Name], [Recv.Name]       the documented file's package. A name the
+ *                             package does not declare is plain text for
+ *                             go/doc: CBM_DOCLINK_LOCAL, neither edge nor row.
+ *                             So is the documented declaration's own type
+ *                             parameter. Recv.Name is a method declared with
+ *                             that receiver, a method of that interface, or
+ *                             a field of that struct (the field is a
+ *                             deliberate difference from go/doc: see
+ *                             go_bind_member).
+ *   [pkg], [pkg.Name],        pkg with a '/' is an import path. Otherwise, in
+ *   [pkg.Recv.Name]           order: the documented FILE's import of that
+ *                             name; the package's own name; a standard-library
+ *                             package with that one-element path. None of
+ *                             them: plain text (see go_lookup_qualifier for
+ *                             the one place this is stricter than go/doc).
+ *   import path               a module of the repository (every go.mod, the
+ *                             longest module path first) -> its directory's
+ *                             package; no package there: missing. No module:
+ *                             external. An import without a name is called by
+ *                             the real package name of an in-repo directory,
+ *                             else by go/doc's assumed name.
+ *   member through an alias   `type X = pkg.Y`: [p.X.Member] is looked up on Y.
+ *
+ * The members of a type are the methods declared with that receiver, the
+ * fields of its own struct declaration and the methods of its own interface
+ * declaration: nothing promoted through embedding.
+ *
+ * Binding. The graph keeps one node per qualified name, and <dir> is the
+ * directory, not the package clause. Go method nodes are receiver-qualified
+ * (<dir>.<Recv>.<Method>, #1913) and are found through their receiver only.
+ * Functions, types and values of one name, in every file of the directory,
+ * share one node <dir>.<name>, and the node is ONE of those
+ * declarations (cbm_gbuf_upsert_node keeps the smallest file path, then the
+ * last line). So a reference binds only when the node IS the entity it names:
+ * the node's file is a file of the named package, the declaration that keeps
+ * the name in that file (the w field of its scope record) is the named entity
+ * (its kind; for a method, its receiver), and the node has that kind's label.
+ * Every other declared entity is a graph_gap. A receiver-qualified method node
+ * (<dir>.<Recv>.<Method>) is tried first, so a graph that names methods that
+ * way binds them all. Only a node's qualified name, label and file_path are
+ * read: the proxy nodes of an incremental run carry no lines and no
+ * properties (the one exception is the SOURCE node, see go_source_owns_node).
+ *
+ * One name, several declarations. Files whose build constraints exclude each
+ * other declare variants of ONE entity, and any of them may hold the node. Two
+ * files built unconditionally that declare the same name are no package (a
+ * directory of stand-alone programs, test data): two entities share the name.
+ * Such a name binds only from a file that declares it itself, to that file's
+ * own declaration; from anywhere else it is ambiguous. A node kept by a test
+ * file is no target for product code.
+ *
+ * Reasons: external (standard library, module dependencies, vendored or
+ * not), missing (a repository package that does not declare the name; an
+ * import path inside a module without a package there), graph_gap (declared,
+ * but the node is another declaration's or absent: block variables, later
+ * names of a declaration, embedded fields;
+ * also an undeclared name in a package with a parse error), test_only_target
+ * (product code naming a declaration that only test files have), ambiguous
+ * (several modules or packages fit; a name declared as two kinds; a name two
+ * unconstrained files declare),
+ * unparseable (a reference longer than CBM_DOCLINK_GO_REF_MAX, an import path
+ * the scan could not record, an alias chain longer than GO_ALIAS_DEPTH).

+ * doc_links_jvm.c — Javadoc and KDoc reference resolution for doc_links.h.
+ *
+ * One index over the Java and the Kotlin files of a repository, built from
+ * their doc-link scopes (internal/cbm/doclink_jvm.c): on the JVM a package is
+ * one namespace whatever language declares into it, so a Kotlin import of a
+ * Java class and a Javadoc link to a Kotlin class must meet in one type table.
+ * The language of the SOURCE file decides the lookup order; where a target's
+ * node is comes from the target's own scope record (slot, own), never from a
+ * naming scheme assumed here. Graph nodes are looked up by qualified name
+ * only, and only their label and file path are read, so the closure-repair
+ * route (whose unchanged nodes are line-less proxies) resolves exactly as a
+ * full build does.
+ *
+ * Entities. A type entity is its binary-style name: package + '.' + the
+ * dotted logical path (com.acme.Outer.Inner). Several declarations of one
+ * name (source sets, expect/actual) are one entity. A member belongs to the
+ * declaration that holds it; overloads of one type share a node.
+ *
+ * Lookup (the first level with a visible candidate decides; more than one
+ * entity there is ambiguous, never a pick):
+ *   Java type name (javac's order)
+ *     the method's own type variables (local) -> the enclosing types,
+ *     innermost first (the type and its member types, its type variables, the
+ *     member types it inherits) -> the file's own top-level types and its
+ *     single imports (a static import imports a member type too) -> the
+ *     file's package -> on-demand imports, with java.lang among them.
+ *     A qualified name: the head through those levels, the rest as member
+ *     types; a head no level has is read from the root (packages, then a
+ *     type). `Type.member` is no reference: Javadoc wants a '#'.
+ *   Java METHOD, `#m` and `Type#m`: javadoc's own search (jr_walk, read in
+ *     the JDK source), from the documented definition's type or the type
+ *     named: the type's own methods -> its superclass, by the whole search
+ *     (its superclass, its interfaces, the type around IT) -> its
+ *     interfaces in the order written, likewise -> the type around it,
+ *     likewise; each type once, the first method found. A type outside the
+ *     repository on the way, or a method the language gives (Object's,
+ *     Enum's, Annotation's, an enum's values/valueOf, a record's
+ *     equals/hashCode/toString), ends it as `external`. Static imports are
+ *     no step: javadoc does not search them for a member.
+ *   Java FIELD, `#x` and `Type#x` without a parameter list: javadoc looks in
+ *     the type, then the types around it, then the supertypes; an inherited
+ *     field binds only when no type further out has one of that name, else
+ *     it is ambiguous. ({@value Type#X}: the type and its supertypes.)
+ *   Java kinds
+ *     `#x` is the field when javadoc takes it over the method its search
+ *     finds: the field's class is the method's class or below it, also for
+ *     every type outside the repository the search passes (jr_java_field);
+ *     else that method, when it is one of the repository with nothing
+ *     unseen before it (javadoc links it), or external.
+ *     A parameter list selects callables:
+ *     the first type whose overloads have that signature, never another
+ *     overload. A declared type variable matches its own name or its erasure.
+ *     A method name without a list that has several signatures is ambiguous.
+ *     A record's component declares an accessor of its name (no node).
+ *     `#Type(..)` names the constructors of that type only. A bare
+ *     identifier that is no type is javadoc's `#identifier`.
+ *   Kotlin (the order KDoc resolves in)
+ *     the definition's own parameters, type parameters and `this` (local) ->
+ *     each enclosing type, innermost first: what it holds itself together
+ *     with its companion (one scope), its type parameters and constructor
+ *     parameters (local), then what it inherits and what its companion
+ *     inherits -> explicit imports -> the file's package (types and top-level
+ *     declarations) -> star imports -> default imports.
+ *     A FUNCTION or PROPERTY found further out than an enclosing type binds
+ *     only when that type is known not to have a member of the name: a type
+ *     that has it from the language (kotlin.Any's members, an enum class's),
+ *     or whose supertypes leave the repository, makes it `external`
+ *     (jr_kotlin_simple). A type found further out binds.
+ *     A dotted name: the qualifier is a type (through those levels, or from
+ *     the root) and the last name what that type holds, inherits, or gets
+ *     from an extension in scope whose receiver it is (an extension only
+ *     where the type's supertypes all lie in the repository: a member comes
+ *     before an extension); or the qualifier is a
+ *     package and the last name one of its types or top-level declarations.
+ *   Kotlin kinds
+ *     a type and a function of one name at one level (a class and its factory
+ *     function) are the type: KDoc resolves a classifier before a function
+ *     (jr_kl_result). A type without a node of its own is then a graph gap,
+ *     never the function. A property and a function of one name are
+ *     ambiguous, and so is an overload group.
+ *     A `[name]` that resolves to nothing is plain text to KDoc (Markdown):
+ *     no reference at all. @see, @throws and @sample name their subject and
+ *     keep a row.
+ * Visibility: product code never binds a declaration that only test code
+ * holds (test_only_target, no fallback to it); `@sample` is exempt.
+ * External: a name a single import brings from a package the repository does
+ * not declare; a qualified `pkg.Type` whose package it does not declare; a
+ * name only an on-demand import of such a package can supply; java.lang and
+ * the Kotlin default imports (the languages' own implicit imports, the only
+ * name lists here, and consulted after the repository's own declarations); an
+ * all-lower-case path under `java`, `javax` or `kotlin` (the platforms' own
+ * namespaces; no library family is one), or under a package the file imports
+ * from and the repository does not declare; a
+ * member that a supertype outside the repository may declare; the members
+ * every type has without declaring them (Object's, an enum's).
+ * Not indexed: a package below one the repository owns, in a directory the
+ * indexer skips by name (discovery's own rule, no file system access here).
+ * Graph gaps: a declaration without a definition (slot '-'), one whose
+ * qualified name another declaration took (own 0), a node of another kind or
+ * file, a package (it has no node), a member a parse error hides, a name the
+ * scan could not place, a definition in a part of its file it could not
+ * place -- and a reference that resolves, written on a definition that has
+ * no node of its own to leave from.

+ *   - a step outside the repository may hold the method; the field's class

+ *     never stops the field; Enum's or Annotation's only an enum's or an
+ *     annotation type's; a record's or an enum's own implicit one, a field
+ *     of that type or below it;
+ *   - against a method of the repository the field binds when its class is
+ *     below the method's class. Otherwise, with nothing the index cannot see
+ *     before that method, javadoc links the method, and so does the reference
+ *     (the lead's ruling of 2026-10-04: a certain binding), with the tier of
+ *     a member the search finds; an overload group without a list stays
+ *     ambiguous, as for any method. If a step outside was passed, the method
+ *     there may be the one: external;
+ *   - a type whose members a parse error hides may hold the method: a graph
+ *     gap, unless the field's class is below it (then it is passed, and only

+ * doc_links_md.c — Markdown references -> MENTIONS edges: the resolving half.
+ *
+ * A Markdown reference (doclink_md.c) names a repository PATH, so it is looked
+ * up in the graph as written: the File node, or the Folder node, at that path,
+ * read relative to the document's own directory and -- for a path with a
+ * directory part -- relative to the repository root as well (documents are
+ * written both ways). A file name alone is read relative to the document
+ * only: a file of that name elsewhere in the repository is not what the
+ * document says (the field tests' rule for bare file names).
+ *
+ * Into the file: a line range picks the innermost code definition that holds
+ * the WHOLE range; a member (`path::Name`, `path::Owner::name`) picks the one
+ * definition of that name in the file. Otherwise the edge goes to the file,
+ * and the range stays on it ("target_lines"). Every edge is exact: the
+ * document wrote the path.
+ *
+ * Unresolved:
+ *   missing    the path is not in the graph, but its directory is: the
+ *              document names something that is not there (doc rot)
+ *   ambiguous  a file name alone that is not next to the document but exists
+ *              elsewhere in the repository: the document does not say which
+ * Not a reference to this repository at all (LOCAL: no edge, no row): a link
+ * back into the same document; a path that is neither indexed nor of a type
+ * the indexer reads (an image, an archive, an extensionless page); a path
+ * whose directory is not in the repository either (a file a tutorial asks
+ * the reader to create, a system path, a path above the root); and, in a
+ * code span, a rooted single segment without a file extension, which is a
+ * URL route (`/docs`, `/health`), not the directory of that name.

+/*
+ * doc_links_msbuild.c — MSBuild global usings of a C# project (R1).
+ *
+ * A reader of data, never a build: nothing is executed, fetched or opened.
+ * The input is the scope blob the extractor writes for every MSBuild project
+ * file the index holds (internal/cbm/doclink_cs.c, "Project blob"). A file
+ * discovery did not take -- a symbolic link, a path outside the repository,
+ * an ignored file -- does not exist here.
+ *
+ * Evaluation model (MSBuild's passes, reduced):
+ *   files       the nearest Directory.Build.props above the project, the
+ *               project file, the nearest Directory.Build.targets; an
+ *               <Import> is evaluated where it stands, every file once
+ *   pass 1      properties in evaluation order, later wins
+ *   pass 2      <Using Include|Remove> items with the final properties;
+ *               Static="true" names a type, Alias an alias; a Remove takes a
+ *               target out wherever it was included
+ *   implicit    ImplicitUsings enable/true adds the default set of the
+ *               project's SDK (Microsoft.NET.Sdk / .Web / .Worker)
+ *
+ * Nothing is guessed. A condition has three values: true, false, and UNKNOWN
+ * for what this reader cannot decide -- a property no evaluated file sets
+ * (the SDK, the environment or the command line may set it), a property
+ * function, an item or metadata reference, a relational operator, a function
+ * call, a comparison whose outcome depends on how MSBuild converts its
+ * operands. An element under an unknown condition is not applied and is
+ * counted. What it could have set is unknown from there on: its properties
+ * poison the conditions that read them, and a <Using> or an ImplicitUsings
+ * switch that cannot be evaluated leaves the project's usings open
+ * (cbm_msb_result_t.open).
+ *
+ * Paths: $(MSBuildThisFileDirectory) and $(MSBuildProjectDirectory) are
+ * absolute in MSBuild. Here they start with a mark byte followed by the
+ * repository-relative path, so an import through them is not joined to the
+ * importing file's directory a second time, and a path the file writes
+ * absolute itself (/usr/..., C:\...) stays what it is: outside.

+ * doc_links_pdf.c — PDF mentions -> MENTIONS edges: the resolving half.
+ *
+ * A PDF page (doc_pdf.c) names code structurally: a path or a qualified name.
+ * The tiers are the field-tested ones (E6, frozen resolver), EXACT or UNIQUE
+ * only:
+ *   path-exact   the mention is a File/Folder node's repository path
+ *   path-suffix  exactly one File/Folder whose path ends with the mention at a
+ *                '/' boundary
+ *   qn-exact     exactly one node whose qualified name (project prefix off)
+ *                is the mention
+ *   qn-suffix    exactly one node whose qualified name ends with the mention
+ *                at a component boundary -- or whose owner-qualified name
+ *                does (parent_class + name: a Go method's QN has no receiver)
+ * Two candidates that are one entity collapse first (a class and its
+ * constructors; duplicate nodes of one definition). A cross-line join is
+ * resolved before anything else in its file: when it resolves EXACT or
+ * UNIQUE it replaces the line fragments it was built from.
+ *
+ * Hygiene (the field test's R2 and R4): a reference that resolves to a data
+ * file (.json, .yaml, ...) is no code reference; one that resolves into a
+ * test, mock or fixture file is a test_only_target row.
+ *
+ * Unresolved: ambiguous (several entities); missing (nothing, but the
+ * mention's first component is a name or directory of this repository).
+ * Anything else names code outside the repository: LOCAL, no row.
+ *
+ * Targets exclude the labels the incremental route does not proxy (Macro,
+ * Comment, Section, Branch, Commit, Tag) and the field test's non-code labels
+ * (Project, Route, Channel, Decorator), so a re-resolved document binds what a
+ * full build binds.

+/*
+ * doc_links_perl.c — resolving Perl POD L<> references (doclink_perl.c).
+ *
+ * A page is a module. L<Mojo::Base> binds the module whose file declares
+ * `package Mojo::Base;` (the scope blob's P records). When several files
+ * declare it, the one the library layout names (…/Mojo/Base.pm) is the
+ * module; more than one such file, or none among several, is ambiguous. A page
+ * the repository does not declare (CPAN, the Perl core, a .pod page:
+ * discovery keeps no .pod file, so nothing can say it is in the repository)
+ * is external, and so is a man page (L<crontab(5)>).
+ *
+ * The target of a module is its File node: a POD page is the file it is
+ * written in (the field test's audited rule). Its Module node would do for
+ * most, but not where a same-named Folder holds the module's qualified name
+ * (lib/Mojo.pm next to lib/Mojo/).
+ *
+ * A section, L<Module/section>: when a heading of the module's file reads
+ * `section` (POD text as it renders, cbm_doclink_perl_plain_text) and names a
+ * sub that has a definition in that file, the target is the sub; headings
+ * that name two subs are ambiguous. A section that names no sub is a place in
+ * the module's documentation: the target is the module. L</section> is the
+ * same page: a sub its heading names binds; a heading that names no sub is a
+ * place in the source's own page, no reference worth an edge or a row
+ * (local); a section the page has no heading for is missing (doc rot).
+ *
+ * Test code (t/, xt/, *.t, and cbm_is_test_file) is bound only from test code.
+ * Every edge is exact: a module name and a heading are spelled out in full.
+ *
+ * The scope blob carries no lines (doclink_perl.c). A dropped sub is repaired
+ * file by file (pl_scope_delta); a change that adds a sub, or adds or drops a
+ * package or a heading, is a full re-resolution; an edit inside a sub changes
+ * no blob.

+/*
+ * doc_links_php.c — resolving PHP doc references (doclink_php.c). A reference
+ * is a FQSEN as phpDocumentor reads it, resolved with PHP's own name rules.
+ *
+ * Forms: `\Ns\Type`, `Type`, `Type::method()`, `Type::$property`,
+ * `Type::CONSTANT` (an enum case too), `function()` and `\Ns\function()`;
+ * `self::`, `static::` and `parent::` with a member. A member written without
+ * `()` and without `$` is a constant or enum case, else a method.
+ *
+ * Names. A leading backslash is taken as written. Otherwise the first segment
+ * of a type name is replaced when it is the alias of a class `use` of the
+ * namespace block the reference is written in (aliases compare without case),
+ * else the block's namespace is put in front: phpDocumentor's rule. Two rules
+ * go beyond that tool, as PHP itself has them: an unqualified function name
+ * is taken from a `use function` import, else from the current namespace,
+ * else from the global namespace; and `self` and `static` name the type the
+ * doc sits in, `parent` that type's superclass. Beyond both, as authors
+ * write it: a bare `name()` in the doc of a type (or of its members) that
+ * declares or inherits a method of that name is that method; a `use
+ * function` import of the name still wins. Type, function
+ * and method names compare without case, properties and constants with it.
+ * The global fallback cannot see a function a dependency declares in the
+ * current namespace: a reference to one binds the global function of that
+ * name (a residual).
+ *
+ * Members are looked up on the type, then on the traits it uses, its
+ * superclass and its interfaces, each of them the same way (depth first; the
+ * first declaration found wins). Nothing found where a supertype is outside
+ * the repository is external; nothing found with every supertype in the
+ * repository is missing.
+ *
+ * Outcomes. A type, function or method binds to its graph node. A property,
+ * constant or enum case has none (a graph gap), nor has a type or function
+ * the graph folds into another one of the same name in its file (the scope
+ * flags those). A type or qualified function the repository does not declare
+ * is external when the first segment of its name is no namespace the
+ * repository declares (PHP's built-ins, Composer dependencies), else missing;
+ * an unqualified function nobody declares is external (PHP's built-in
+ * functions). Two declarations of one name are ambiguous unless one is in the
+ * reference's own file. Test code binds only from test code. Edges are exact
+ * for a name written fully qualified or bound by a use import, unique
+ * otherwise.

+ * doc_links_rs.c — Rust intra-doc link resolution for doc_links.h.
+ *
+ * The index is built from the scope blobs of the repository's Rust files and
+ * Cargo manifests (internal/cbm/doclink_rs.c); nothing is read from disk.
+ * Graph nodes are looked up by qualified name only, and a node is taken only
+ * when its label and file are the declaration's, so the closure-repair route
+ * (line-less proxy nodes) resolves exactly as a full build does.
+ *
+ * Model.
+ *   package     a Cargo manifest with [package]: its directory, edition and
+ *               dependencies. A dependency names a crate of the repository
+ *               only through `path` (its own, or the workspace table's)
+ *   crate root  a target root file of a package: the lib (src/lib.rs or
+ *               [lib] path), src/main.rs, src/bin/, tests/, benches/,
+ *               examples/, build.rs, and explicit target paths
+ *   module      a file's root module or an inline `mod x { }`. A `mod x;`
+ *               attaches the file rustc would read: x.rs or x/mod.rs beside a
+ *               crate root, a mod.rs or a `#[path]` file, under <stem>/ beside
+ *               any other file, or the `#[path]` file. A file can be attached
+ *               more than once and belong to several crate roots; a file no
+ *               root reaches is an orphan
+ *   binding     what a module declares under a name: an item, a child
+ *               module, a named import, a name a macro invocation may declare
+ *
+ * Lookup follows rustc's name resolution as rustdoc applies it to intra-doc
+ * links, one namespace (type, value, macro) at a time:
+ *   first segment  `crate` (every crate root of the file), `self`, `super`
+ *                  (repeatable), `Self` (the impl's self type, the trait, or
+ *                  the documented type), `::name` (extern prelude), else
+ *                    1. the module's own bindings
+ *                    2. its glob imports, through re-exporting globs, only
+ *                       names visible to the importing module
+ *                    3. the extern prelude: std, core, alloc, proc_macro,
+ *                       test, the package's dependencies, and the package's
+ *                       own lib from its other targets
+ *                    4. the std prelude, primitive types, std macros
+ *                  The first level with a binding in the namespace decides. A
+ *                  level whose content is not known (a glob of an external
+ *                  module) is not looked past.
+ *   later segments a module's levels 1 and 2; for a type: enum variant, items
+ *                  of its inherent impls, then items of trait impls whose
+ *                  trait is in scope of the documenting module, then (value
+ *                  namespace) fields; for a trait its own items; type aliases
+ *                  are followed
+ * The candidates of the namespaces are united. One entity binds. A trait and
+ * a derive macro of one name are the trait (rustdoc's rule). Anything else
+ * with two or more is ambiguous. A disambiguator or suffix restricts the
+ * namespace and the kind; an entity of another kind is no match.
+ *
+ * Nothing is resolved around what the scan could not place: in a file with a
+ * parse error (or constructs the blob cannot carry) a name its modules do not
+ * show is a graph gap, never looked up further out; so are a name a macro
+ * invocation may declare, an import that cannot be followed, a `mod` whose
+ * file is not indexed, and `crate::` or `super::` from an orphan file.

+ * doc_links_rst.c — reStructuredText references -> MENTIONS edges, via "rst"
+ * (the resolving half of internal/cbm/doclink_rst.c).
+ *
+ * Python domain (roles, object directives, autodoc) as the field test's
+ * resolver (H3 PyResolver) reads it. A dotted name is read like Python's
+ * import system: its longest prefix that is a module's import name (a .py
+ * file, or a package's __init__.py, named from its topmost package
+ * directory down) and the rest as a qualified name in that module; a
+ * package's re-export (`from .base import Model` in its __init__.py, read
+ * from the Python scope blobs of doclink_py.c) continues the lookup at its
+ * source. Forms in Sphinx's search order: T, Class.T, module.T,
+ * module.Class.T (a leading `.` searches the most specific first). EXACT
+ * when one form names a node. Otherwise UNIQUE by name: the one Python
+ * definition named like T's last piece whose qualified name ends with T --
+ * for a T of two or more pieces only (a bare name is never searched: the
+ * field test's errors were bare names), under a module context the one
+ * inside the module when several are, and for an object directive (which
+ * declares its object IN its module) only inside it.
+ *
+ * C domain: a C identifier is the whole name -- the one C or C++ definition
+ * of that name and kind (H3 CResolver), a member through its struct.
+ *
+ * Paths: include / literalinclude (relative to the document; `/x` relative
+ * to its documentation set: the directory of the nearest conf.py),
+ * kernel-include and kernel-doc (relative to the repository root, as the
+ * kernel's Sphinx extensions read them), extlink roles whose URL is a
+ * repository blob path. A literalinclude's :lines: bind the innermost
+ * definition holding them, its :pyobject: the named definition. Inline
+ * literals: the Markdown resolver's code-span rules (doc_links_md.c).
+ *
+ * Unresolved: ambiguous (several), missing (the name's first piece or the
+ * path's directory is the repository's), test_only_target (only test code has
+ * it), unparseable. Anything else is LOCAL: another project's name (the
+ * standard library, an intersphinx name), a bare name no context resolves.

+/*
+ * doc_links_ts.c — resolving TypeScript and JavaScript doc references
+ * (doclink_ts.c), one index over TS, TSX and JS files, which import each other.
+ *
+ * A reference is a path: segments joined by `.`, `#` (an instance member) or
+ * `~` (a module's member), with an optional `()` or meaning suffix
+ * (`:class`, `:0`) that is dropped (one node holds every overload). Its first
+ * segment is looked up as the TypeScript checker would see it from the
+ * documented declaration, and the field test's prototype does:
+ *   1. the declaration's own parameters (dropped at extraction);
+ *   2. the namespaces around the reference's line, innermost first;
+ *   3. the file's own top-level declarations;
+ *   4. the file's imports: named, default and namespace imports, followed
+ *      through `export { a as b }`, `export ... from` and `export *` barrels
+ *      (a cycle guard and a depth bound; two barrels that answer differently
+ *      are ambiguous); a relative specifier resolves with the usual extension
+ *      and index rules; a bare one through the nearest tsconfig/jsconfig
+ *      `paths` (the first target, as TypeScript tries it first) or
+ *      `baseUrl`, else, when it is the `name` of a workspace package (the
+ *      pipeline's package map), to that package's entry module (`exports`,
+ *      `main`, `module`) when the repository indexes it; every other bare
+ *      specifier, a package's subpath included, is external;
+ *   5. the standard library's global names: external;
+ *   6. the top-level declarations of the repository's script files (files
+ *      without an import or an export are global): one binds, several are
+ *      ambiguous;
+ *   7. the members of the documented declaration's class or interface (of the
+ *      declaration itself for a class or interface doc), `this.` included.
+ * Nothing found is missing. The other segments walk members (a node's
+ * qualified name + `.` + segment) or a module's exports. A member a class,
+ * interface or enum declares without a node of its own is a graph gap. Test
+ * code binds only from test code. Edges are exact for a name the file
+ * declares or imports, unique otherwise.

+ * pass_docker.c — the container build layer.
+ *
+ * PHASE 4 P4.1a: what a Dockerfile builds on. Each base it names DEPENDS_ON
+ * an Image node -- an edge from the Dockerfile's Module:
+ *   FROM <image> [AS <stage>]          {via:from}
+ *   COPY --from=<image> ...            {via:copy-from}
+ * A stage of the same file is no image (FROM builder, COPY --from=builder or
+ * --from=0), nor is `scratch`. ${ARG} references are expanded from the ARG
+ * defaults in scope (global ARGs before the first FROM; a stage's own ARG and
+ * ENV); a reference without a value leaves the image unknown, and an unknown
+ * image is no edge.
+ *
+ * Image identity is the repository as written, tag and digest dropped (they
+ * stay on the edge). Its registry is the host the reference names -- Docker
+ * Hub's spellings as docker.io, with library/ for an official one-segment
+ * image -- else "unknown": no host is invented for a reference naming none.
+ *
+ * PHASE 4 P4.1b: what the container runs. The last stage's ENTRYPOINT (else
+ * CMD) SPAWNS -- from the Dockerfile's Module {api:dockerfile}:
+ *   the repository file it runs     a script / source copied into the image
+ *                                   (an interpreter's script, a path, a CMD
+ *                                   file under an inherited ENTRYPOINT)
+ *   the Go `main` of the package    a binary `go build -o` made in a stage
+ *                                   and the image copied in
+ *   a Process                       any other program
+ * Container paths map back through COPY: a context source is looked up under
+ * the Dockerfile's directory and the repository root -- the one where it is
+ * the file (or Go main package) wanted, else nothing; COPY --from=<stage>
+ * continues in that stage. WORKDIR makes paths absolute. `sh -c`, a variable
+ * program and arguments to an inherited ENTRYPOINT are no edge.
+ *
+ * PHASE 4 P4.5: the environment a container is given. Each variable a K8s
+ * container's env, a compose service's environment or the last stage's ENV
+ * (with the stages it is built FROM) sets is an EnvVar of that container
+ * (image, for ENV) -- `<owner QN>#env/<container | ->/<name>`, owned by the
+ * declaring file -- the owner CONFIGURES {strategy:env_set, source}. The
+ * global EnvVar a program's readers share is not joined: the same name is
+ * read by other programs (measured: 23 % of such joins in scope). Values are
+ * never read into the graph.
+ * Run at the end of the K8s pass.

+ * pass_envjoin.c — F1: which program reads the variables a container sets.
+ *
+ * P4.5 gives each variable a container sets an EnvVar of its own
+ * (`<owner QN>#env/<container | ->/<KEY>`); a program's readers point at the
+ * global EnvVar of the name (CONFIGURES {strategy:env_access}). The same name
+ * is read by many programs, so the join connects a setter only to the
+ * readers inside its container's own program -- the files its image is built
+ * from:
+ *   EnvVar -CONFIGURES {strategy:env_read, dockerfile}-> reader
+ * The image: a K8s container's literal image (USAGE {ref:image, container})
+ * built from exactly one Dockerfile (Image -DEPENDS_ON {via:build}->); a
+ * compose service's own build edge, else its image's; a Dockerfile's own ENV.
+ * Its files: the Dockerfile Module's image_files (pass_docker.c) less the
+ * image_ignore patterns, never a test file. Measured on 17 corpora: 80
+ * pairs, 80 correct; a join through the global name was in the program for
+ * 23 % of the pairs.
+ *
+ * Every run recomputes every such edge. An incremental repair holds only the
+ * changed files' nodes and edges: the unchanged files' inputs come from the
+ * store (cbm_envjoin_base_t, read before the K8s pass), and the patch replaces
+ * the stored edges wholesale.

+ *
+ * A package's namespace holds what its __init__ imports, not only what it
+ * defines: `models.CharField` exists because django/db/models/__init__.py
+ * star-imports its fields module. This turns a module's ordered namespace
+ * facts (cbm_extract_python_namespace_facts) into records next to its
+ * definitions:
+ *   PyReexport    a name the module's imports bind at the end of its top
+ *                 level: short_name = the bound local, receiver_type = the
+ *                 import's RAW module spec (one '.' per relative level, then
+ *                 the dotted module), method_names_str = the imported member
+ *   PyStarImport  `from X import *`: receiver_type = X's raw module spec
+ *   PyAll         a literal `__all__`: method_names_str = "a|b|c"
+ * Records are content-only -- built from the facts alone, with no import map
+ * and no graph -- so every driver, the incremental surface probe and the
+ * stored surface rows produce the same bytes for the same source, and the
+ * records of an unchanged file travel through its surface row. The Python
+ * cross registry resolves the specs to project modules and folds the records
+ * into its export table (py_build_module_namespaces). The replay is
+ * conservative: a later own definition, module import, shadow or delete drops
+ * a name; a whole-namespace UNKNOWN fact (an effect, a compound statement)
+ * drops everything recorded before it, and later exact facts record again;
+ * `__all__` is published only as a literal. Facts that are not COMPLETE

+ * pass_operator.c — Go Kubernetes operators (PHASE1 P1.2).

+ *   - a controller is built `For(&v1.Widget{})`, `Owns(&v1.Gadget{})`,
+ *     `Watches(&v1.X{}, ...)` or watches `source.Kind(cache, &v1.X{})`:
+ *     HANDLES {via: controller, role} from the function that builds it to
+ *     the Go type, resolved as Go does: `v1` is an import of the file, and
+ *     the type is the struct of that name in the imported package's
+ *     directory (unqualified: the file's own package);
+ *   - a CRD's group/kind is backed by `type <Kind> struct` in the package
+ *     marked `+groupName=<group>` (or `GroupName = "<group>"`): USAGE
+ *     {ref: crd-type} from the CRD Resource to that Struct;
+ *   - `//go:embed <patterns>` puts files into the binary: REFERENCES_FILE
+ *     {via: go:embed} from the Go file to each embedded file;
+ *   - an installer loads a chart of the repository (helm.LoadChart(
+ *     filepath.Join(opt.ChartsDirectory, ...)), the Helm SDK's loader):
+ *     DEPLOYS {via: helm-sdk} from the function to the Chart (PHASE 3 P3.3).
+ * Runs after USAGE resolution; reads each Go file once, and the files that

+ * pass_shell.c — the Bash (+ Make, CI) infrastructure layer (PHASE 3 P3.2, P3.5).
+ *
+ * A shell script or a Make recipe that puts manifests, a kustomization or a
+ * chart on a cluster DEPLOYS them: an edge from the function running the
+ * command (a bash function, a Make rule; top-level code: the Module) to the
+ * node of what it deploys -- existing nodes only:
+ *   kubectl apply|create|replace -f F     a File holding Kubernetes objects:
+ *                                         F itself, F's *.yaml|*.yml|*.json
+ *                                         (-R: below it), or a glob's matches
+ *   kubectl ... -k D                      the Kustomization of D
+ *   kustomize build D | ... | kubectl apply -f -   (also kubectl kustomize D)
+ *   helm install|upgrade [NAME] CHART     the Chart of a chart dir, else the
+ *                                         external Chart of that name
+ *                                         (repo/name, oci://.../name)
+ *   helm template [NAME] CHART | ... | kubectl apply -f -
+ *   find D -name G -exec kubectl apply -f {} \;    D's manifests matching G
+ *
+ * A program started by a path (./_build/kubermatic-installer, ${DIR}/x,
+ * $(LOCALBIN)/controller-gen) SPAWNS the Process of its name, as
+ * pass_spawns.c draws a call that starts a program. A program that is a file
+ * of the repository -- the path names one, or a shell runs one
+ * (bash|sh|zsh|ksh|dash [-opts] FILE) -- SPAWNS that script instead: its
+ * Module (the source of its own top-level edges), else its File (P3.5).
+ *
+ * CI (P3.5): the command lines GitHub Actions steps and Prow job containers
+ * run (pass_ci.c reads them) evaluate the same way, from the step's
+ * directory with its env literals; their edges carry the CI and the job.
+ *
+ * Words are evaluated by constant propagation over the script, nothing is
+ * executed: assignments (local / export / readonly / declare, arrays and
+ * "${a[@]}"), ${X:-default}, $0 / BASH_SOURCE, $(dirname ..), $(basename ..),
+ * $(cd .. && pwd), $(realpath ..), $(pwd), $(git rev-parse --show-toplevel).
+ * A word with any other part is unknown, and an unknown target is no edge.
+ * A value set in a branch, a loop or the right side of && / || is unknown
+ * after it; a subshell's or pipeline element's changes do not leak; a
+ * function body is read where it is defined, and the globals it sets are
+ * unknown after it. cd / pushd / popd track the working directory. A
+ * relative path resolves against it; with none tracked (a script runs from
+ * wherever it is started), against the repository root and the script's
+ * directory, linked only when exactly one of the two names a target.
+ *
+ * Make: the Makefile's variables expand into each recipe line (recursively,
+ * with the last assignment; $(CURDIR) / $(shell pwd) are the Makefile's
+ * directory, where its recipes run), which then evaluates as a shell line of
+ * its own. A variable assigned under a conditional is unknown; an included
+ * .mk file runs in its includer's directory, so it tracks none.

+ *      Go, Java, Kotlin, Rust, Perl, TS/JS, PHP and C hold MENTIONS edges;
+ *      diagrams are Diagram/DiagramElement nodes with DIAGRAM_ARROW edges;
+ *      OpenAPI operations are Routes; a Markdown section's text keeps a

+ *      src/unix/) keeps its path QN and carries a `variant_key` property
+ *      (its platform-neutral QN) that relates its platform variants.
+ *   8: a file and the directory beside it with one stem (`pkg/foo.sh`,
+ *      `pkg/foo/`) no longer share a QN (cbm_stem_marks_t): the Folder is

+ *     which call C/C++ declarations from shared headers directly.
+ *   - JVM: Java/Kotlin/Scala/Groovy call each other's classes directly (the

+ *   - .NET: C#/F#. PHP: PHP/Blade. Go: Go/templ (templ compiles to Go).

+ *     SQL: SQL/PL-SQL. Salesforce: Apex/SOQL/SOSL. HDL: Verilog/SystemVerilog.
+ *     CFML: tag and script dialects. ObjectScript: UDL/routine/export.
+ *   - Swift additionally calls the C family (C and ObjC headers import into
+ *     Swift as native declarations), and Python calls ObjectScript (IRIS
+ *     Embedded Python, iris.cls(...), #1260) and back.

+ * graph_mem.h — read-only in-memory adjacency over a published store's edges.
+ *
+ * A graph walk on a kernel-scale index (8.5M nodes, 16.9M edges) spends its
+ * time in SQLite B-tree seeks: trace_path's recursive CTE took 6.6 s and a
+ * degree-filtered search_graph 3.9 s, where the same questions on django take
+ * 20-100 ms. This layer reads the edges ONCE, in one sequential scan of the
+ * covering UNIQUE(source_id, target_id, type, ...) index, into a typed CSR
+ * (node id -> out/in neighbours, each with its interned edge type) and answers
+ * those walks from RAM. Node rows still come from SQLite; only the edge
+ * structure is held.
+ *
+ * Identity: a layer is keyed by (db path, version), where the caller promises
+ * that one version names one edge set. store.c builds the version from the
+ * store generation (every publish stamps a new one) plus the rollback-journal
+ * file state (the header change counter every commit bumps — it also catches
+ * writers that mutate a published DB in place without a new generation), and
+ * admits only read-only query stores of a sealed, non-legacy DB.
+ *
+ * Lifetime: the daemon closes its query stores after every request, so layers
+ * live in a process-wide registry, shared by refcount across request threads.
+ * Every byte is allocated through the memory core (CBM_MEM_CLASS_GRAPH_CACHE)
+ * and the registry is bounded: the layers together stay under a quarter of
+ * the memory budget, unheld ones are evicted oldest-first to make room, and a
+ * layer that still would not fit (or that would push the process over its
+ * budget) is not built — the caller keeps the SQL path. A build is
+ * all-or-nothing: a failed or refused build leaves no partial layer behind.
+ * A layer nobody held for CBM_GRAPH_MEM_IDLE_EVICT_MS is evicted on the next
+ * request (no timer thread), and the daemon subtracts the resident bytes from
+ * what it hands index workers (cbm_graph_mem_cached_bytes).

+ *     is, among the parents one hop closer, the one with the smallest (rank of
+ *     the edge type in the request, qualified name). Node ids, row order and
+ *     seed order never take part;

+/* atlas_why.c — the Why view: "when does this run?"
+ *
+ * The condition→action abstraction (Pennington 1987) served on demand: for a
+ * symbol, its callers with the SYNTACTIC guard chain around each call site —
+ * the enclosing if/else/switch/loop/ternary conditions, outermost first,
+ * collected by walking the tree-sitter parse of the caller's file upward
+ * from the call line. Guards are honest approximations: what the code
+ * lexically wraps the call in, never proven path conditions.
+ *
+ * Zero indexing cost: CALLS edges already carry the call-site line, and the
+ * embedded grammars parse the few caller files live per request. */

+/*
+ * test_conditional_variants.c — one definition with mutually exclusive
+ * variants is ONE identity in the graph, in every language.
+ *
+ * A variant is a second definition of the same name that only one build or
+ * run ever sees: C-family #if/#else, C#/F# #if, Rust #[cfg], Swift #if,
+ * Go build-tagged files, D version blocks, Erlang -ifdef, Haskell CPP,
+ * Fortran .F90 preprocessing, Verilog `ifdef, Elixir/Python/Ruby/PHP
+ * definitions under an `if`. C platform files (foo_win.c / foo_posix.c) are
+ * the exception: each keeps its own node and path QN, so it is found by its
+ * file, and they share a `variant_key` (cv_platform_check below).
+ *
+ * Every fixture defines `pick` twice — variant A calls `alpha`, variant B
+ * calls `beta` — plus a `caller` that calls `pick`. The graph must hold:
+ *   - exactly one node for `pick` (no per-variant twins, no condition text
+ *     in its qualified name);
+ *   - CALLS from that node to alpha AND beta (every variant's body counts);
+ *   - a CALLS edge from caller to it;
+ *   - its `variants` property listing every variant's span, so a change in
+ *     any variant maps to the definition.
+ * Fixtures avoid each language's unrelated extraction gaps (Ruby and Pascal
+ * calls carry parentheses; Haskell calls are applications).

+# The per-test coverage map builder: scripts/test-impact/coverage-map.py.
+#
+# The map decides which tests of a spawn-heavy suite a change can reach, so what
+# it must never do is claim that a test executed less than it did. This script
+# pins the cases where it cannot know, each of which has to come out
+# `incomplete` (always selected) instead of as a short function list:
+#   - a forked child left its marker (its coverage is not accounted for);
+#   - a profile that cannot be read;
+#   - a test with child profiles but none of the runner itself;
+#   - a suite that did not exit 0.
+# It also pins the bookkeeping the engine relies on:
+#   - a function is named by the SOURCE FILE its body stands in, taken from the
+#     coverage mapping of the runner, not by the translation unit the profile
+#     names: a unity build and a header's static inline would otherwise carry a
+#     file the graph does not know them under;
+#   - one function seen from two translation units is one row;
+#   - a function the mapping does not list keeps what the profile says;
+#   - ids in tests.tsv name rows of functions.tsv;
+#   - what ran between tests lands on `<suite>:*`;
+#   - the runner is started with a plain LLVM_PROFILE_FILE;
+#   - no raw profile survives the run.
+#
+# Hermetic: a fake runner writes the profile files a real instrumented runner
+# would, a fake llvm-profdata reads function names out of them and a fake
+# llvm-cov prints a coverage mapping. Building the real instrumented runner
+# takes minutes and belongs to the map job.

+ * main thread, whose size depends on the platform and its rlimit. Each probe
+ * below therefore runs cbm_extract_file on a thread of exactly that size, so
+ * a walker that recurses once per nesting level runs out of stack at the

+ * and an overflow surfaces as the child's killing signal instead of taking
+ * the runner with it (the pattern of tests/test_stack_overflow.c); Windows
+ * runs it in-process, where a real overflow is a visible runner abort. A
+ * probe returns 0 when every expectation held and prints what did not.
+ *
+ * DEEP_NEST_LEVELS: a walker frame holds at least its saved frame pointer and
+ * return address plus the 32-byte TSNode it passes down (on arm64 a TSNode is
+ * passed by reference to a copy in the caller's frame), 48 bytes, so 200,000
+ * frames need 9.6 MB — past the 8 MB worker stack even at that floor;
+ * measured frames are larger and the sanitizer build adds red zones. The
+ * parser is not the limit: tree-sitter keeps the nesting on its heap parse
+ * stack and its node and cursor helpers are iterative, so the depth is the
+ * walker's problem alone. The fixtures nest parentheses, which copy no text
+ * per level (a nested call copies its argument text at every level, which is

+# A red suite's summary must show WHY it is red, whatever killed it.
+#
+# Why: a Windows sanitizer job went red on one suite that aborted under
+# AddressSanitizer, and the job log held nothing a reader could act on:
+#
+#   ──── index_resilience: every failure site ────
+#   ──── index_resilience: last 15 lines ────
+#     (the AddressSanitizer shadow-byte legend)
+#   ==6636==ABORTING
+#
+# The summary grepped the suite log for "FAIL" only, and a sanitizer report
+# never contains that word. Its useful part (error kind, access size, top
+# frames) is at the START of the report, far above the last 15 lines. With no
+# log artifact either, the cause had to be found by reading code a day later.
+#
+# This drives the REAL functions (scripts/suite-failure-report.sh, which the
+# parallel harness sources) with fabricated suite logs written the way
+# tests/test_framework.h writes them, so the contract cannot drift from the
+# code it pins. No build, no network, no waiting: every case is a file in and
+# text out.

+ * test_kotlin_typed_calls.c — Kotlin member calls through a class PROPERTY
+ * (primary-constructor `val`, body property, `this.prop`) bind to the
+ * property's declared type, on both resolver venues (#1555).
+ *
+ * The cross-file Kotlin walk resolved a typed method PARAMETER by type, but
+ * a property-typed receiver fell to the name guess: the cross registry held
+ * the class from extraction defs (properties untyped, constructor vals
+ * absent), and the walk's typed AST registration of the same class was
+ * shadowed by that earlier entry. Each fixture call has a same-named decoy
+ * method on another type, so a name guess is visible as a wrong target:
+ *   - Service.log: `audit.inserir()` on `audit: Audit`, next to
+ *     `repository: Repo` whose interface also declares inserir (the
+ *     sequential venue's guess picks Repo.inserir);
+ *   - two bounded contexts whose use cases both inject `repository`
+ *     (the parallel venue's receiver-name guess bound the feriado use case
+ *     to CompromissoRepository.inserir, the #1555 report).
+ * One fixture, padded past MIN_FILES_FOR_PARALLEL, is indexed through the
+ * sequential resolver (CBM_INDEX_SINGLE_THREAD=1) and the parallel one.

+# Lane-gate contract: the two aggregate gates under lane selection.
+#
+# With lane selection a PR runs a SUBSET of its jobs, and a subset is exactly
+# where a silent gate loss hides: before selection a `skipped` job only ever
+# meant "not needed for this PR", so ci-ok could wave every skip through. Now a
+# selected lane whose jobs were skipped, cancelled or never created looks just
+# as quiet. So:
+#   - scripts/ci/require-all-green.sh (ci-ok): given the selector's LANES and
+#     the run's JOBS, a SELECTED lane must have run and succeeded; an
+#     unselected lane may be skipped or absent; memwaste never gates.
+#   - scripts/ci/verify-shard-union.sh (shard-completeness): "no manifests" is
+#     green only when the selection holds no test leg at all; with legs (or
+#     with no selection given: dry run, release) it stays a failure.
+# Both scripts are driven with synthetic inputs, never copied.

+# Lane-wiring contract: the workflows honour the lane selection, and only PRs

+#

+#      _test.yml / _lint.yml / _security.yml, whose inputs default to "all"
+#      (and "standard"): those runs execute every job, sharded, exactly as
+#      before lane selection. Only pr.yml asks for the PR shard profile.
+#   2. pr.yml feeds the selector's lanes to every reusable workflow, runs the
+#      T0a/T0b contracts job, and hands ci-ok both the selection and the
+#      run's job list (actions: read) -- ci-ok needs `contracts` but never the
+#      report-only memwaste / shadow jobs, and the shadow is continue-on-error.
+#   3. every lane of scripts/ci/select-lanes.sh --list-lanes is served by a
+#      job: matrix lanes as a "lane":"<name>" tag in the leg data (the tag
+#      ci-ok reads back from the job name), single lanes by an `if:` that
+#      names them. A lane nothing serves would be selected and never run.
+#   4. the test selection (smart CI) is PR-only and fails open: _test.yml's
+#      test_selection defaults to empty and only test-unix / test-windows
+#      read it; dry runs and releases never pass it; pr.yml's select-tests

+# Lane-selector contract: scripts/ci/select-lanes.sh decides which PR lanes a
+# change set runs, so a wrong answer is a SILENT gate loss -- a lane that
+# should have caught a regression simply never starts, and ci-ok (which only
+# demands the lanes that were selected) stays green. This pins the decision
+# table case by case (tests/fixtures/select-lanes/cases.tsv), and the
+# properties the workflows lean on:
+#   - fail-safe: an unmatched path, an empty list, the selector itself, any
+#     workflow, the test harness, Makefile.cbm and vendored code select FULL;
+#   - determinism: order and duplicates never change a byte of the output;
+#   - one decision per input channel: stdin, a file, --batch and the
+#     github-output form all agree;
+#   - a truncated file list (the pulls/files API stops at 3000) selects FULL.

+# Test-impact prediction contract: scripts/test-impact/predict.py turns a
+# detect_changes impact set into the C test suites a change can affect. It
+# feeds the PR test-impact SHADOW job -- report-only, never a gate -- but a
+# shadow that silently under-predicts would make its own evaluation lie, so
+# the mapping and its fallbacks are pinned on a synthetic tree:
+#   - impacted test functions map to their registered suites (perf excluded;
+#     a nested suite resolves to the registered suite that runs it);
+#   - a changed test file always selects its whole suite;
+#   - a changed fixture selects the suites whose tests name it;
+#   - run-all: the selector's full, a test header, a saturated or truncated
+#     impact set -> every suite;
+#   - no C change -> the graph is not consulted, nothing is predicted.
+#

+ * Fork provenance (pinned; the commit this repo vendored before the fork):
+ *   Isopod/tree-sitter-pascal @ 042119eca2e18a60e56317fb06ee3ba5c32cb447 (v0.10.2)
+ *     grammar.js -> this file = upstream + this header + patches/unicode-identifiers.patch
+ *   (the grammar has no external scanner)
+ *
+ * The patch (and nothing else) differs from upstream: upstream's identifier token
+ * is ASCII-only ([&]?[a-zA-Z_]+[0-9_a-zA-Z]*), so a Delphi identifier with
+ * non-ASCII letters -- e.g. the Cyrillic member names of 1C's OLE API called
+ * through late-bound Variants -- became an ERROR node and the unit was flagged
+ * parse_partial. The patched token takes a Unicode letter or '_' first, then
+ * letters, combining marks, decimal digits or '_'. Keywords are still extracted
+ * from this `word` token, so they lex as before; node types are unchanged.
+ * On an upstream bump: re-fetch the pinned grammar.js, re-apply the patch,
+ * regenerate, re-run test/corpus -- and drop the fork if upstream fixes it.
+ *
+ * Regenerate (ABI 14, as the upstream pin; NEVER use a CLI >= 0.26, which emits
+ * ABI 16):
+ *   cd tools/tree-sitter-pascal
+ *   npx tree-sitter-cli@0.25.10 generate --abi 14
