**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).
[Quick start](#quick-start) · [Explore CBM Lens](#cbm-lens-beta-code-visualization-and-source-navigation) · [Chat with your codebase locally](#chat-with-your-codebase-locally) · [MCP tools](#mcp-tools) · [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).

**Galaxy.** Explore the code knowledge graph in 3D. The recording searches `cbm_pipeline_run`, follows its outgoing calls one layer further, switches to the hierarchy and shows the path to `cbm_store_check_integrity`.

## 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.
- **CBM Atlas** — the built-in human interface at `localhost:9749`: a reading IDE over the index (explorer and read-only Monaco reader, a semantic twin that follows the caret, flow, bug-hunt and change-scope reading modes, the 3D galaxy, source-cited answers, project management), served from the binary itself.
- **Infrastructure-as-code indexing** — Dockerfiles, container images, docker compose, Kubernetes manifests, and Kustomize overlays indexed as graph nodes with cross-references. `Resource` nodes for K8s kinds and compose services, `Image` nodes joining the images that are built and run, `Module` nodes for Kustomize overlays with `IMPORTS` edges to referenced resources — a Service walks to the program its container runs.
- **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.
- **Indexing performance**: 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 (arm64/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. No separate parser installation.
- **About 120× fewer tokens in the reported five-query comparison**: ~3,400 tokens vs ~412,000 via file-by-file search. See [Performance](#performance) for the scope and sources.
- **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.

### Session Coordination Daemon
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.

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 a session-managed daemon stops after the final session. A daemon started with `daemon start` remains running until stopped. 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.

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.
Package-manager setup (npm, PyPI, or Go) verifies and publishes a coherent private cached runtime set. Sidecars are replaced before the executable with per-file atomic renames; an interrupted multi-file publication is detected and repaired on the next launch rather than being described as one crash-atomic filesystem transaction. It does not replace the active native installation and therefore does not stop running CBM sessions. When that cached binary is executed, it still enters the same exact-build admission barrier. The shell and PowerShell installers invoke the verified candidate's native `install` command, so they do receive the full account-wide activation guarantee.

Its connection is a `cli_session`: it never registers with the background watcher and never starts a UI, and it holds the admission lease only for the command's lifetime. If the command's own connection is what started the daemon, that daemon exits again once the command closes and no other session is attached; if a daemon was already running, the command simply joins and leaves it exactly as found. While the command is running, a temporary monitor separately lets activation cancel that operation and its supervised worker safely; the monitor exits with the command and never becomes a standing daemon.

### CBM Lens Beta — the human interface
### CBM Lens Beta: code visualization and source navigation
The MCP tools are the agent's interface to the code graph; **CBM Lens Beta** is the human's. It is built into the binary — every install on every channel has 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.
CBM Lens builds on **CodeAtlasWeb**, a reading IDE built by [Bernhard Jackiewicz](https://github.com/BernhardJackiewicz) on the CBM read surface (design and tracking in #1964). It runs air-gapped on loopback, reaches no cloud, and every panel names where its facts come from; what the index did not record is shown as a gap, never filled in with a guess.
**Open your first repository**
When something in CBM Lens does not load, the page has already written it down: its console output, uncaught errors and failed requests go to `${CBM_CACHE_DIR}/logs/ui.log` (default `~/.cache/codebase-memory-mcp/logs/ui.log`, one JSON line per entry, rotated once at 5 MiB). The projects panel (alt+p) shows the tail under "This server", `GET http://localhost:9749/api/ui-log?lines=200` returns it, and a bug report can attach the file.
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.
- **Explorer and reader** — the indexed file tree and a read-only Monaco reader whose source comes from the index.
- **Semantic twin** — follows the caret: what the symbol under it holds, calls, raises and touches, as facts or as pseudocode, pitched at who is reading.
- **Reading modes** — `[w]hy am I here` picks a way in (hunt a bug, scope a change, understand the project, pick an entry point); **flow** walks the calls in the order they run; **bug hunt** compares the expected path into a symbol with what `ingest_traces` observed; **change scope** shows what a change reaches and what covers it.
- **Galaxy** — the persistent 3D graph with focus following in both directions, and a hierarchy view of the entry subgraph.
- **Command line** — search by meaning while you type; a line ending in `?` builds a source-cited answer from indexed fact cards, with an optional local-model wording pass (a llama-server sidecar you start yourself; off by default, and no model or binary ships).
- **Live agents** — an opt-in overlay of AI agents working in the same repository, fed by a loopback bridge over tool-hook events (`graph-ui/agents/`).
- **`[p]rojects`** — index a repository, check or remove an index, edit the project's decision record, and see the server's processes and log.
- **`[?]help`** — what it reads, what it cannot do, and every key it listens to, derived from the wiring itself.
To bookmark a view, use `?project=<name>&workspace=architecture`. Other workspace values are `explore`, `galaxy`, `adr`, `coverage`, and `system`.
Open a project with `?project=<name>` in the address, or pick it in the projects panel. The frontend's own README, plan, honesty rules and recorded proof runs live under `graph-ui/`.
| 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.

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.

### Graph & analysis
- **Architecture overview**: `get_architecture` returns languages, packages, entry points, routes, hotspots, boundaries, layers, and clusters in a single call
- **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

- **`CROSS_*` edges** link nodes across multiple repos indexed under the same store
- **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"}]`.
### Edge types (selected)
- `CALLS` — a callable is invoked at the source site
- `CALL_REFERENCE` — a callable is used at a supported reference site (for example, a direct value argument) and resolves to one exact target
- `USAGE` — an identifier is used, but a unique callable target is not proven (including ambiguous or complex expressions)
- `CALLS`: a callable is invoked at the source site
- `CALL_REFERENCE`: a callable is used at a supported reference site (for example, a direct value argument) and resolves to one exact target
- `USAGE`: an identifier is used, but a unique callable target is not proven (including ambiguous or complex expressions)
- `IMPORTS`, `DEFINES`, `IMPLEMENTS`, `INHERITS`
- `HTTP_CALLS`, `ASYNC_CALLS` (cross-service)
- `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
- `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 chart outside the repository is a shared external `Chart`; the edge says `via` (`flux`, `argo`, `helmrelease`, `kubectl`, `kustomize`, `helm`, `helm-sdk`, `terraform`, ...)
- `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)
- `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`.

- `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). A templated target links nothing. Each task and handler is a `Function` (named by its `name:`, else its module; `source: ansible`, `kind`, `module`) that its file `DEFINES`: in a playbook's plays, a role's `tasks/` and `handlers/` files, and the files those include; a block's tasks, not the block. A `notify` `CALLS` (`via: notify`) each handler of that name or `listen` topic in the task's own role (else its file). A `kube` (kubespray's module) or `kubernetes.core.k8s` task `DEPLOYS` (`via: ansible`, `module`) the repository file its play rendered the applied manifest from: the `template` (in the role's `templates/`) or `copy` (its `files/`) task whose `dest` is the task's `filename`, item by item through `register` / `with_items` / `loop` lists the play states (a literal list, a `set_fact`, the role's `defaults` / `vars`), or a `k8s` `template:` argument

## Team-Shared Graph Artifact
Commit a single compressed file to your repo and your teammates skip the reindex.
Share a compressed graph snapshot so teammates can reuse an indexed baseline.
`.codebase-memory/graph.db.zst` is a zstd-compressed snapshot of the knowledge graph that lives next to your source. The artifact is opt-in: `index_repository` writes it only with `persistence: true` (the default is `false`), and once it exists later indexes refresh it; when a teammate clones the repo and runs `codebase-memory-mcp` for the first time, the artifact is decompressed and incremental indexing fills in their local diff.

The artifact is opt-in: `index_repository` writes it only with `persistence: true` (the default is `false`), and once it exists later indexes refresh it. Local indexes persist regardless. When a teammate indexes a clone with an existing artifact, CBM imports that baseline and applies their local changes incrementally.

- **Format**: SQLite database, indexes stripped, `VACUUM INTO` compacted, then zstd 1.5.7 compressed (8 to 13:1 ratio typical)
- **Two tiers**:
- **Best** (`zstd -9` + index strip + `VACUUM INTO`) — written by `index_repository` with `persistence: true`
- **Fast** (`zstd -3`) — refreshes an existing artifact on every other index (including the watcher's low-latency incremental updates)
- **Bootstrap**: when no local DB exists but the artifact is present, `index_repository` imports the artifact first, then runs incremental indexing — avoiding the full reindex cost
- **No merge pain**: a `.codebase-memory/.gitattributes` line with `merge=ours` is auto-created on first export, so concurrent edits don't produce conflicts on the binary artifact
- **Commit it deliberately**: the artifact is rewritten on every index, including the watcher's Fast tier, and git stores each rewrite as a full new blob. Committing every refresh is what turns a 20 MB file into gigabytes of history — one team reached ~6 GB across ~350 commits of this single path. Pick a cadence (a release, a milestone, a nightly job) rather than committing every save.
- **Git LFS, if it must move on every commit**: track it from the **repo-root** `.gitattributes` and leave the auto-created `.codebase-memory/.gitattributes` in place — the nearer file goes on supplying `merge=ours`, and only `filter` comes from the root:

```
Track only the `.zst`; `artifact.json` is small and carries the schema version. The attribute applies to future commits only, so a repo that already has the blobs in history needs `git-filter-repo` to rewrite them first. Two costs to weigh before adopting it: GitHub meters LFS storage and bandwidth, and its objects cannot be pruned without contacting support; and every teammate needs `git lfs install` — without it their checkout leaves a pointer file where the artifact should be, the integrity-checked import refuses it, and they fall back to a full reindex.
- **Optional**: never committed unless you want it. Add `.codebase-memory/` to `.gitignore` if you prefer everyone to reindex from scratch.

- **Optional**: shared export is opt-in, and Git commits remain your choice. Add `.codebase-memory/` to `.gitignore` if you prefer everyone to reindex from scratch.
The result is similar in spirit to graphify's `graphify-out/` directory, but as a single compressed file with explicit two-tier export, integrity-checked import, and zero merge friction.
The artifact provides a shared baseline while each developer keeps a local query database.
## How It Works
codebase-memory-mcp is a **structural analysis backend** — it builds and queries the knowledge graph. It does **not** include an LLM. Instead, it relies on your MCP client (Claude Code, or any MCP-compatible agent) to be the intelligence layer.

**Why no built-in LLM?** Other code graph tools embed an LLM for natural language → graph query translation. This means extra API keys, extra cost, and another model to configure. With MCP, the agent you're already talking to *is* the query translator.
With MCP, your coding agent translates a question into tool calls. CBM Lens can also use an optional browser model for explanations; this does not change how the backend indexes or queries code.

## 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`:

| File | What it is |
|------|------------|
| `trajectory.ndjson` | **The memory trajectory** — one JSON line every 5 s with `rss`, `committed` (Windows commit charge), `peak_*`, `page_faults`, `fd`, and `queries`. **This is the file we need for memory/leak reports** — the *trend over time* is what pinpoints a leak. 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.

Every platform ships **one self-contained executable**: the graph UI and the agent integration templates are linked into the binary, so an extracted archive is immediately complete.
The `--with-ui` build embeds CBM Lens and the agent integration templates into the native executable. You do not need Node.js to run that executable. Optional browser model weights are downloaded separately after opt-in.

Tree-sitter alone gives a syntactic AST. That handles naming, structure, and call sites well, but it can't tell you that `user.profile.display_name()` resolves to `Profile.display_name` declared three modules away — tree-sitter doesn't track imports, generics, inheritance, or stdlib types.

codebase-memory-mcp ships a **lightweight C implementation of language type-resolution algorithms, structurally inspired by and compatible with major language servers** (tsserver / typescript-go, pyright, gopls, Roslyn, Eclipse JDT, rust-analyzer), embedded directly into the native executable. 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.

**Two-layer architecture:**
1. **Tree-sitter pass** — fast, syntactic, runs for every one of the 162 languages. Extracts definitions, calls, imports.
2. **Hybrid LSP pass** — type-aware, runs above the tree-sitter pass per-language. Refines call edges using the import graph plus a per-file or pre-built cross-file definition registry. Languages without a Hybrid LSP pass yet fall back to textual resolution, so you always get *some* answer.

The result is a knowledge graph accurate enough to drive `trace_path` across packages, inheritance hierarchies, and stdlib calls — without paying for a language server process per project.

Every release is verified through a multi-layer pipeline before publication:
- **VirusTotal** — all 24 executable candidates (unstripped, debug-stripped and stripped) across the eight release products are scanned before smoke/soak (clean is preferred and only the single-Microsoft `!ml` tolerance documented in [SECURITY.md](SECURITY.md#our-release-policy) may pass; the number of engines that returned a decisive result is recorded as evidence but is VirusTotal fleet availability, not a pass condition).

# 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.
## Two layers
```
changed files ──► Layer 1: lane selector ──► which CI jobs run
(scripts/ci/select-lanes.sh, your own rules)
│
▼ (the Linux x86_64 test leg only, in this repo)
merge base + PR ─► Layer 2: test-impact engine ─► which suites / tests run
(codebase-memory-mcp test-impact select
+ team-artifact bundle from main)
```
| | 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.

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`).

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.
## Refreshed stills: 13 October
`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.

/* ── One definition, two parses: which copy the rescue keeps ──────────────
*
* The #961/#1989 rescue re-extracts definitions from the preprocessed parse to
* 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
* the expanded pass does not know, leaves that intact).
* A real nested type keeps its nesting: the expanded parse still holds it
* inside p, so r is not replaced, and r's own QN follows p's move. */

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).

Conservatively walks the production tree (including prebundled dependencies;

the first line of their shipped license file; if that cannot be resolved
either, the gate fails — unknown is not allowed.
Walks the WHOLE production tree (including prebundled dependencies and
platform-restricted native packages) and fails if ANY package's license is not
on the policy allow-list. There are no exceptions: a package that is installed
but never bundled still blocks, because "unshipped" is a claim about a build,
and a non-permissive license must never be one build change away from shipping.
Packages with no declared license fall back to the first line of their shipped

not allowed. The current app + worker build evidence must also verify.
