Mark Tranandwyuc 55e324768e fix: keep videos playing inline on mobile (#1321)
* fix: keep videos playing inline on mobile

Add playsInline to every playback video path, including the legacy app renderer, renderer-backed playback, and the shared renderer package. This keeps mobile browsers such as WeChat on Android from interrupting inline playback and restarting videos after an interruption.

Add regression coverage for both app renderer modes and the package renderer.

* chore(renderer): bump package version

* chore(renderer): bump package version to 0.1.6

Burak Keskinandwyuc 03bd449320 fix(settings): turn TTS and media generation on from the Settings page (#1311)
* fix(settings): turn TTS and media generation on from the Settings page

The global enable flags only auto-set on first provider sync, and Settings
had no switch for them, so a later API key never started narration or
image/video generation. Add the Settings toggles and turn each flag on
when that provider first becomes usable.

* fix(settings): route media enablement through isUsableMediaProvider

A force-disabled image or video provider could still flip the global flag
from a key paste, and keyless providers never did. Use the same usable
transition as TTS, including a baseUrl for lemonade and comfyui.

Mahesh Singh c938f5e082 fix(asr): bypass AI SDK for custom providers to handle extra response… (#1283)
* fix(asr): bypass AI SDK for custom providers to handle extra response fields

Custom ASR providers (e.g. SiliconFlow) return OpenAI-compatible JSON but
include extra fields like segments, duration, and usage that the
Vercel AI SDK's strict Zod response schema does not expect, causing it to
throw an 'Invalid JSON response' error.

Previously, custom-asr-* providers were routed through
transcribeOpenAIWhisper() which delegates to the AI SDK's
experimental_transcribe. The SDK validates the raw HTTP response against a
strict schema, so any provider-specific extra field fails parsing even when
the 	ext value itself is perfectly valid.

Fix: introduce transcribeCustomOpenAICompatibleASR() which calls
/audio/transcriptions directly via raw fetch (the same approach already
used by funasr-asr and lemonade-asr). It extracts only data.text from
the response, making it tolerant of any extra fields a provider may return.
The official openai-whisper case is unchanged and still uses the SDK.

Fixes #1277

* style: fix prettier formatting in asr-providers.ts

* fix(asr): require model ID for custom providers, add regression test

Address review feedback from CXuPercy (#1283):

- The previous implementation silently omitted the model FormData field
  when config.modelId was falsy. Most OpenAI-compatible transcription
  endpoints treat model as required, so a custom provider configured
  without a model ID would go from working (via transcribeOpenAIWhisper's
  fallback) to silently sending a modelless request and getting a 400.

- Fix (Option A — fail fast): validate config.modelId before building
  the request and throw a descriptive error if it is missing, so the user
  gets a clear message rather than an opaque 400 from the upstream API.

- UI contract: the settings panel already shows an amber warning
  'Please add at least one model before using this provider' and the
  Add button is disabled when the model ID field is blank, so the
  UI is already aligned with the fail-fast behaviour.

- Update all 12 test cases to supply a modelId, and add a dedicated
  regression test 'throws when no model ID is configured' to prevent
  this from regressing silently again.

mehmet turacandwyuc a7e9dc8337 fix(providers): apply server-pinned models for image and video providers (#1298)
* fix(providers): apply server-pinned models for image and video providers

The server-providers API already exposes image models, and the server
resolves them correctly, but getServerVideoProviders() omitted the
models field entirely, and fetchServerProviders() on the client side
discarded the models payload for both image and video — it only set
isServerConfigured and serverDisabled.

This caused the client to fall back to built-in model IDs, which fail
on endpoints that require different IDs (e.g. Volcengine Ark Agent Plan
uses dotted aliases like doubao-seedream-5.0-lite).

Server: getServerVideoProviders() now exposes models, mirroring the
image listing. Client: fetchServerProviders() stores the server model
list as customModels with replaceBuiltInModels: true for both image and
video, matching the existing LLM provider model-filtering pattern.

Fixes #1251

Zhenghan Songandwyuc 3d0d74065e test(media): isolate force-off test from OpenAI fallback (#1303)
Why:
- A shell-exported OPENAI_API_KEY enables the generic image fallback inside a test that expects every configured media provider to be disabled.
- The resulting fetch-mock failure includes the Authorization header in local test output.

What:
- Mask the generic OpenAI key only for the force-disabled media test before provider configuration is imported.
- Reuse the existing Vitest environment cleanup to restore the caller's shell environment after the test.

Risk:
- Test-only change; production provider fallback behavior and the global shell-environment policy remain unchanged.
- Dedicated provider-config coverage continues to exercise the generic OpenAI image fallback.

Tests:
- Focused force-disabled test with OPENAI_API_KEY=openmaic-test-sentinel
- Full classroom-media-generation test with and without the sentinel: 8 passed
- tests/server/provider-config.test.ts: 107 passed
- Full root suite with the sentinel: 7137 passed, 81 skipped
- Prettier, ESLint, TypeScript, and i18n quality gates

Live Docs:
- GitHub issue #1302; test-environment policy remains documented by PR #1162.

wyuc f6cf8fd4b7 feat(agent): make generate_video asynchronous with a placeholder ref (#1267)
* feat(agent): make generate_video asynchronous with a placeholder ref

The generate_video tool awaited the whole provider submit/poll/download/
persist cycle inside the tool call, blocking the agent turn for minutes
(and effectively capping it at the 10-minute tool budget, below its own
15-minute internal budget).

The tool now validates synchronously, mints a gen_vid_<id> placeholder
(the scheme the outline flow already uses), and returns immediately so
the agent can patch_stage the ref onto a video element and keep
working; the element renders the existing skeleton while pending. A
detached background job (own 15-minute timeout, deliberately decoupled
from the caller's abort so a cancelled chat cannot silently orphan a
billable provider job) runs the provider cycle, persists the bytes, and
then:

- patches the persisted document: every slide video element still
  referencing the placeholder gets the concrete server-hosted src
  (same runStageMutation discipline as the generation tools; skipped
  silently when the element was changed meanwhile), and
- appends a media_ready lifecycle event to the session's durable log
  via the session-level control channel (valid post-run, unlike the
  runner's lease-guarded emit); the workbench folds it into the media
  generation store so the skeleton resolves instantly, on live stream
  and on replay.

Pending tasks live in a process-local registry; a server restart
orphans in-flight jobs (the placeholder keeps its skeleton), matching
the classic flow's client-local durability caveats. Tracked as an
accepted v1 limitation.

Closes #1266

* fix(agent): unfence the background video patch from the run lease

Review findings on the async generate_video change:

- P1: the completion patch wrote through the run's owner-bound store,
  whose mutation fence asserts the run lease on every write. A video
  job settles minutes after its run ended and the lease is released,
  so every post-run patch threw AgentSessionLeaseLostError and the job
  wrongly settled failed. The runner now builds a dedicated owner-bound
  store for media jobs fenced only by the stage-mutation discipline,
  and the tool takes it as a separate backgroundStore dep.
- P2: patchStageVideoPlaceholder rewrote whole scenes from one
  minutes-old loadDocument snapshot. It now re-reads each candidate
  scene immediately before its write and applies the placeholder swap
  to the freshest state, so concurrent user/agent edits survive; the
  residual read-write window matches the stage edit API's own
  read-modify-write discipline.
- P3: drop the dead 'emit' progress marker (setPendingMediaStage is a
  no-op after settle), emit a media_ready failed frame from the
  last-resort crash guard so a bug path cannot leave the client on a
  permanent skeleton, and log when appendControlEvent silently drops a
  frame for a deleted session.

* test(agent): cover the concurrent placeholder-element removal case

Round-2 review leftovers: pin that patchStageVideoPlaceholder skips
rather than resurrects a placeholder element deleted between the
candidate scan and the write, and keep the detached job's crash guard
synchronous (never-rejecting helpers only) so a future throw inside it
cannot become the unhandled rejection the guard exists to contain.

* fix(agent): isolate the completion patch from the provider budget

Round-3 review leftovers:

- The patch shared the job's 15-minute signal, so a provider cycle that
  nearly exhausted the budget could fail mid-patch and rebrand a
  persisted, downloadable asset as failed. The patch now runs on its
  own 60-second budget and a patch failure is logged while the job
  still settles and emits done (the done frame's src renders fine).
- A user edit that replaced the placeholder with a concrete src while
  the job ran no longer gets clobbered by the stale mediaRef: the swap
  only writes while src is absent or still the placeholder.

Accepted, documented: the sub-second read-write window between two
concurrent jobs on the same scene (the client-side media fold renders
either way), and the failed-state fold requiring an attached chat
stream in v1.

* fix(agent): close the regeneration gap in the placeholder src guard

Delta review found the new patch-failure test never attempted the write
(no element carried the runtime ref, so putScene was never called), and
that the src guard also skipped legitimate patches: an element
re-pointed at a new job via mediaRef while still carrying the previous
generated src (which keeps rendering the old video), and an empty src.

The guard now also writes when src is empty or a previously generated
/api/classroom-media/ URL; the test seeds the ref so the failing write
is really attempted and asserts the logged patch failure.

* fix(agent): harden the placeholder src guard

- Total predicate: a malformed non-string src no longer throws inside
  the element map and aborts the whole stage patch.
- Recognize the absolute-form generated src the classic pipeline
  persists, and scope the generated-src arm to the stage's own media
  root so a user's pick copied from another stage is preserved.

wyuc aa7d5fd585 feat(agent): let generate_scene pass widgetType and widgetOutline for interactive pages (#1259)
* feat(agent): let generate_scene pass widgetType and widgetOutline for interactive pages

The generate_scene tool schema had no widget fields, so every interactive
page it generated fell back to a simulation widget in the generation
pipeline. Add optional widgetType (simulation/diagram/code/game/
visualization3d; procedural-skill stays gated behind task-engine mode)
and widgetOutline parameters, reject them for non-interactive page
types, and carry them into the constructed SceneOutline. When only one
of the two is provided, mirror the generator's own defaults
(widgetType: 'simulation', widgetOutline: { concept: title }) so
half-specified calls still generate.

Closes #1258

* fix(agent): harden generate_scene widget params from review findings

- Accept procedural-skill in the widgetType union; the handler already
  enables it via allowProceduralSkill and skill constraints can require
  it, so excluding it only produced an opaque schema error.
- Validate widgetOutline is a plain object and reject malformed values
  (null, strings, arrays) with an invalid-widget-outline error instead
  of silently degrading the prompt or surfacing a misleading generic
  generation failure.
- Reject widget fields on non-interactive pages by definedness rather
  than truthiness, matching the tool description's contract.
- Pin the widgetOutline passthrough test to a non-default diagramType
  (mindmap), cover the handler's single-field defaults, cover
  procedural-skill passthrough, and exercise the tool schema through
  TypeBox Value.Check.

* fix(agent): keep procedural-skill gated out of generate_scene

Review feedback: main gates procedural-skill behind taskEngineMode and
OPENMAIC_ENABLE_VOCATIONAL in every generation path, and no vocational
signal reaches the agent runtime, so accepting the literal here would
ungate the feature in every deployment. Drop it from the widgetType
union (back to the first commit's semantics), say so in the schema
description, and pin the gate in the schema validation test. Ungating
for vocational agent sessions can come back as its own change once a
task-engine signal is plumbed into the tool layer.

wyuc dfebbcf33f perf(classroom): speed up classroom loading (media hydration, sidebar thumbnails, media range requests) (#1276)
* perf(classroom): defer non-priority media blob hydration off the load path

Entering a classroom awaited the full mediaFiles restore — one object URL
per restored image/video blob — before the loading gate opened. For
video-heavy courses that is hundreds of MB of IndexedDB materialization
blocking first paint.

Split the restore into two phases:

- The awaited phase now builds metadata-complete task entries but only
  creates object URLs for failed rows (none needed) and for media
  referenced by the scene the classroom opens on (persisted cursor, else
  the first scene). buildRestoredMediaTasks gains an optional
  shouldHydrateBlob predicate, defaulting to eager hydration so existing
  callers are unchanged.
- Remaining blob-backed records hydrate in the background, chunked over
  requestIdleCallback (setTimeout fallback). Each deferred task stays
  'done' — so generation resume never re-runs it — but carries no
  objectUrl yet, which the media resolution state machine already renders
  as a pending skeleton until the URL lands.

Background hydration is guarded per record: a task that was replaced
(classroom switch, regeneration, retry) or that belongs to another stage
is skipped and its freshly minted URLs are revoked immediately.

* perf(classroom): lazy-render slide thumbnails in the playback sidebar

The playback scene sidebar mounted a full SlideCanvas for every slide
scene the moment the classroom opened (and every off-screen video element
opened a preload="metadata" fetch), because SlideThumbnail's existing
visible prop was never passed.

Extract the editor nav rail's near-viewport IntersectionObserver hook to
lib/hooks/use-near-viewport.ts and gate the sidebar's slide thumbnails
through it: only scenes within 200px of the viewport render the live
canvas; the rest show SlideThumbnail's existing placeholder until scrolled
near. The placeholder keeps the same box size, so gating never shifts
layout.

The shared hook now starts hidden instead of eager: with the previous
eager-initial state, opening a long deck still mounted every canvas for a
frame before the observer could flip off-screen items off. The observer's
guaranteed initial delivery flips near-viewport items within a frame; the
no-IntersectionObserver fallback (e.g. jsdom) defers to a microtask so
the effect never synchronously re-renders.

* perf(media): lazy image decoding and HTTP Range support for classroom media

Renderer: BaseImageElement's <img> now carries loading="lazy" and
decoding="async", so thumbnail-heavy surfaces (playback sidebar, editor
nav rail, course cards) no longer fetch and decode every slide image up
front. In-viewport images are unaffected — the browser fetches them
immediately. slideToPng forces eager loading inside its permanently
off-screen snapshot tree, where lazy images would otherwise never fetch
and exports would capture blank slides.

Server: GET /api/classroom-media/[classroomId]/[...path] now answers
single byte-range requests with 206 Partial Content (Content-Range,
Accept-Ranges, correct Content-Length), enabling progressive playback and
seeking for hosted video/audio instead of downloading whole files. Suffix
ranges are supported; unsatisfiable ranges get 416 with the full size;
unsupported units or multi-range sets fall back to the plain 200 full-body
response, which is always a legal answer. Existing caching headers are
kept on every response shape.

* chore(renderer): bump version to 0.1.4 for image lazy-loading change

* fix(classroom): guard deferred hydration against restarted tasks and bound idle waits

A deferred record is only ever 'done' without an objectUrl; a task that
regeneration or retry restarted passes through pending/generating, so skip
those instead of attaching stale persisted bytes. Also give the idle
scheduling a timeout so a busy main thread cannot starve hydration.

* fix(classroom): stop superseded deferred hydration before minting URLs

A restore epoch captured at apply time now gates each idle chunk: loading
another classroom or reloading the same one invalidates any older hydration
loop, so it neither keeps scheduling work for an abandoned classroom nor
attaches bytes read by an older load to a newer load's tasks.

* fix(classroom): keep 416s uncached and classify element-keyed media as priority

A 416 with public immutable caching can poison the media URL for later
valid requests, so range errors now send Cache-Control: no-store. Priority
classification also collects the opening scene's media element ids, since
task lookup binds records keyed stage:<elementId> even when the slide slot
carries a different opaque ref.

* fix(classroom): tie deferred hydration liveness to the classroom load token

The restore epoch only advanced when the next load reached apply, so an
abandoned classroom kept hydrating during the next load's storage/network
phase. Compose the epoch with the load's isCurrent (load token plus effect
cleanup) so navigation stops the loop at the next idle boundary.

* fix(classroom): classify legacy-recovered media before deferring it

Legacy singleton video recovery assigns a placeholderRef only at the end of
the task build, so a record keyed by an allocated id without placeholderRef
was deferred even when it backs the opening scene's gen_vid_* element. Run a
metadata-only build first to learn each record's effective ref and classify
against it, keeping the first visible page's legacy video eager.

* fix(action): wait for deferred video bytes before starting play_video

executePlayVideo treated status done as immediately playable, but a deferred
restore is done without an objectUrl: the renderer shows a skeleton, no
<video> exists, and the later hydration never retriggers play, leaving the
action stuck until the safety timeout. Readiness now follows the renderer's
contract (only done-with-bytes is playable) at the initial check, the
subscription exit, and the post-subscription recheck; the failed skip applies
whether or not a wait happened.

* fix(classroom): include the stage whiteboard in priority media refs

The stage-level whiteboard stays open across standalone classroom switches,
so its media can be visible before any scene is. Classifying it as deferred
left visible whiteboard media pending behind idle hydration chunks.

* fix(dsl): strip legacy rotate/height from line elements on migration and import (#1260)

* fix(dsl): cover whiteboard slides in the legacy line strip, drop redundant import wiring

Round-1 review findings (#1261): the strip only walked
scenes[*].content.canvas.elements, leaving the same bug class latent on
interactive whiteboard slides (scenes[*].whiteboards[*].elements); and the
import-site sanitize was redundant because the document store already runs
the ladder on save, while its comment misdescribed that mechanism. Extend
the strip to whiteboards and let the ladder alone own the cleanup.

* fix(dsl): cover stage-level whiteboard boards and row envelopes in the legacy line strip

Round-2 terminal audit findings (#1261): the strip walked only the
document envelope's scene surfaces, so dirty line elements under
stage.whiteboard (the stage-level explainer boards) and under bare
Scene/Stage row envelopes passed through while the runner stamped the
document current. Walk every line-element surface of every migratable
envelope: scene canvas, scene whiteboards, and stage whiteboard, at
document, Scene-row, and Stage-row roots.

* fix(dsl): gate the canvas strip on the slide discriminant; run the ladder on legacy-only exports

Round-3 terminal audit findings (#1261): the canvas walk fired on any
canvas-shaped content regardless of the scene kind, so a non-slide scene
carrying a canvas-shaped app extension would have fields deleted from it
— gate on content.type ('slide' or absent, the dirty-line epoch predates
schema enforcement). And the lock-free exportDatabase fallback
hand-stamped DSL_VERSION onto a payload the ladder never walked, so a
backup could read as current on restore and permanently skip the
migration — build the export unstamped and let migrate stamp it.

* fix(agent-runtime): bring stale-stamped documents current before incremental scene writes

Round-4 audit finding (#1261): putScene rejects documents whose stored
DSL stamp is older than the current one, and the aggregate read migrates
in memory only, so the first server-side tool write into a course stored
at an older version (every pre-bump course, including previously
imported ones) failed with a version error. Route the server tools'
incremental scene writes through a wrapper whose not-current fallback
reloads the migrated aggregate and full-saves it with the scene spliced
in — the server-side counterpart of the app autosave's
catch-and-full-save.

* fix(agent): repair orphaned and late tool results across interruption boundaries

A crash, shutdown, or provider failure can leave the durable transcript with
tool calls that have no result, or with results ordered illegally for the
provider. Three failure modes were fixed:

- Orphaned tool calls: a run that died between an assistant tool-call frame
  and its result left a dangling call in the entry tree. Resume no longer
  synthesizes and persists receipts for it: interrupted results are a
  read-time provider view owned by a shared read-boundary repair, which
  returns the original array for a healthy transcript and never mutates the
  tree.

- Late parallel results: a parallel tool can finish while pi unwinds an
  aborted assistant frame, leaving result(A), assistant(aborted), result(B)
  in durable order. Strict providers reject non-contiguous results, so the
  read-boundary repair moves existing results next to their owning assistant
  frame (in call order), omits incomplete unwind frames, and synthesizes
  receipts only for genuinely missing calls.

- Interrupted calls at the write boundary: a call still in flight when the
  run winds down (shutdown, lease loss, cancellation, provider failure) had
  no receipt at all. The runner now tracks in-flight calls from their
  assistant frames and, before the terminal flush, appends an
  interrupted-result receipt for each still-orphaned call through the same
  attempt-fenced write chain, so a lease-stealing zombie never writes and

* fix(storage): serialize the user-skill quota check-and-insert per owner

Two concurrent creates at the 50-skill boundary both counted 49 rows and
both inserted (READ COMMITTED, no lock), overshooting the quota contract.
The create transaction now takes a per-owner pg_advisory_xact_lock first,
and the same-name idempotency check runs before the count check so an
at-least-once retry of the create that committed as the owner's 50th row
still returns its durable receipt instead of a quota error. The 23505
backstop is retained for writes that do not take the lock.

The reconciliation test iterates every tool the runner registers and

(list_voices, set_roster, clip_audio, register_voice) reached the
integration base with the roster/voice-registration tools but never
gained presentation rows, so they fell through to the default branch
and rendered their wire names. Port their rows from the reference
implementation (labels and i18n keys verbatim) and extend the
reconciliation allowlist with ROSTER_TOOL_NAMES and
VOICE_CLONE_TOOL_NAMES, so a future tool cannot enter the product
without a label.

* feat(api): folder routes, stage-meta viewer surfaces, and the material upload contract (#1215)

* fix(storage): restore capability-based stage access

* fix(api): bind document access to request owner

* fix(agent): restore three-state stage access on the tool layer

Port probeStageAccess and the three-state StageAccess (owned / foreign /
missing / tombstoned) and gate every stageId-bearing stage tool on an owned
probe, mirroring the reference per tool:

- move_to_folder, rename_stage, read_stage_outline refuse a non-owned stage
  with the single not-yours message before touching the store.
- The course/DSL toolset and the roster toolset are wrapped by
  withOwnerStageAuthorization: read_stage, patch_stage, grep_stage and every
  writer refuse a foreign stage with the same message and refusal shape.
- Scene preview keeps its own probe and its own refusal text, and is
  registered beside the course toolset (never double-gated).
- The runner injects one probe factory at the three call sites.

Tests: the dsl cross-owner test premise (a foreign stage is readable by id)
encoded an invented capability-read policy that the reference does not have
at the tool layer; it now asserts foreign read/patch/grep are all refused
while the owner still reads. Curriculum cross-owner assertions were already
the reference's and now pass with the probes in place.

* docs: correct per-file test counts in the fidelity report

* test: fix type errors in stage-access fidelity test

* test: adapt media-tool and gate suites to the owner-scoped store seam

* feat(api): add owner-scoped course-folder HTTP routes

Port the reference implementation's /api/folders family (list, create,
rename, delete with ungroup/remove modes, and folder membership) onto the
owner-bound document store, replacing its provider-based auth with the
existing withRequestOwnerId / owner-scoped store seams.

The storage package's folder store grows the pieces the routes need:
DocumentFolder.order (schema column + max+1 assignment + ordering),
renameFolder, deleteFolder(mode) with captured member ids, and
setStageFolder(stageId, folderId | null) with idempotent un-filing.
FolderNameError moves into folder-name-validation.ts (stage-storage re-exports
it, keeping import sites intact).

Every route gates on the configured agent runtime (plain 404 when off or
unconfigured), keeps the reference's machine codes and envelopes, and is
covered by gate tests plus a behavior suite.

* feat(api): add stage-meta viewer surfaces for the classroom

Port the reference implementation's viewer-facing stage state — can-edit /
collected / published / generation-complete — on top of the stage-access
base (stage_meta + tombstones). stage_meta gains published_at and
generation_complete columns plus a stage_bookmarks table; the reference's
deployment-specific origin/claimed_at columns are stripped.

New gated routes: GET /api/stage-meta/[stageId] (per-viewer facts, 404 for
absent/tombstoned, never returns the owner id), GET /api/stages/[id]/status,
POST generation-complete / publish / unpublish (owner-only), POST
/api/bookmarks. The resolver lives in lib/server/stage-access.ts.

Wiring: a fetchStageMeta client with the reference's three-outcome contract,
stage-store isOwner/isBookmarked/readOnly fields (upstream single-user
defaults, no-op until the sidecar answers) plus setViewerAccess, the
classroom apply path computing readOnly = !(isOwner || isBookmarked), the
Stage editability gate, and a sidecar probe after each classroom load. A
sidecar 'absent' answer keeps the editable default here because the
classroom also serves local-only courses; server writes stay owner-enforced.

* feat(api): port the reference material upload contract

Rewrite POST /api/materials to the reference implementation's upload shape
so the workbench uploader (uploadWorkbenchMaterial, which posts no session
id and expects a flat 201 view) works unchanged: owner-scoped upload with
mime normalization/validation (415), per-class size caps checked on the
declared content-length and the streamed body (413), empty body (400),
quota (429), sha256 reserve->store->finalize lifecycle with abandon on
failure, flat { materialId, originalName, bytes, mime, extraction } 201,
and an x-request-id echo.

Adds the owner-scoped material library (owner_material table + quota +
24h lazy sweep, bytes in the host's asset registry as the neutral
replacement for the reference's object-storage byte path) and the material
cap configuration. The session-scoped GET list is left as-is; the
reference's owner-material extraction worker is not ported (the branch's
session-material extraction lifecycle already covers extraction).

Gate tests now cover all 23 persistence routes across the three runtime
env states; the materials behavior suite pins the new contract.

* feat(media): add an optional local ffmpeg media extractor (#1213)

Adds a local ffmpeg/ffprobe pipeline as a second media extraction
provider behind the extractor registry, ported faithfully from the
reference implementation: duration probing, keyframe-safe chunking,
per-chunk ASR with timeout and deadline budgets, and timestamped
transcript assembly.

- Availability probing feeds the registry's candidate selection: the
  provider simply is not a candidate when ffmpeg/ffprobe are absent.
- With neither ffmpeg nor a cloud provider configured, extraction fails
  with an actionable message naming both enablement paths.
- Media materials route through the same extraction lifecycle and lease
  fence as documents; no parallel queue.
- Tests inject the executable resolver so the missing-ffmpeg path is the
  default-tested one; the real pipeline test is skip-if-unavailable.
- @openmaic/storage 0.13.0 -> 0.14.0 (media routing in the material
  lifecycle surface).

* feat(storage): per-scene monotonic revisions via database triggers (#1214)

* feat(storage): per-scene monotonic revisions via database triggers

Restore the reference implementation's freshness granularity: a
per-scene monotonic revision maintained by database triggers, so every
writer (HTTP routes, agent tools, jobs, manual SQL) bumps it without
application cooperation.

- Companion revision tables + trigger functions in the storage package's
  idempotent schema bootstrap, with the lock-order invariant, pg_notify
  wakeup and the suppression switch for batch writers.
- ensureDocumentSchema gained a dollar-quote-aware statement splitter.
- The freshness and manifest routes serve per-scene revisions.
- Mutation-verified: dropping the triggers turns the revision tests red.
- @openmaic/storage 0.13.0 -> 0.14.0.

* feat(workbench): add the Pro entry points

* feat(workbench): preserve Pro mode transition semantics

* fix(workbench): drop ambient declarations shadowed by landed slices

* fix(workbench): drop ambient declarations shadowed by the landed shell

* feat: port workspace shell sibling modules

Port the 16 leaf modules the Pro workspace shell imports but that were only
ambient-declared, replacing the compile-time bridge with real implementations
adapted from the sibling-slice reference: pure workbench helpers (session
title, rail tab, course-chat bootstrap, created-course tabs, course-tabs
memory, workspace navigation, pane navigation, pro-edit sizing,
existing-course minting, first-message session), the neutral brand context and
course-rename server API, the server-action session delete, the home
discovery hook, the classroom pane host with its load-policy leaf, the theme
toggle and floating-layer owner, plus the floating-layer-owner wiring the
dialog/dropdown/tooltip portals stamp.

Also add the workbench-shell locale copy for all 12 locales, port the
reference tests for the ported modules, and drop
types/workbench-sibling-slices.d.ts now that every declaration has a real
implementation.

* fix(agent): control-plane routes answer 404, not 500, without a database

The agent control-plane routes gated only on the runtime flag, so an
enabled-but-unconfigured deployment (flag on, DATABASE_URL empty)
answered 500 from a store that cannot connect. Gate them on the
configured check instead, matching the stage/material routes: the
whole surface is cleanly absent until both the flag and the database
are present. The status probe keeps reporting both bits.

* test: mock both runtime gate exports in the control-plane route suites

* fix(agent): abort in-flight TTS on cancel and bound each provider request with a timeout (#1217)

The generate_tts / scene-tts path checked the runner's AbortSignal between
actions but never created the provider HTTP requests with it, so a session
cancel left a hung synthesis fetch in flight until a restart repaired the
tool result. Thread the signal end-to-end: TTSModelConfig carries an
optional signal, generateTTS combines it with a per-request timeout
(TTS_REQUEST_TIMEOUT_MS, default 30s, ported from the reference runtime's
TTS bounds) via AbortSignal.any, and every provider fetch (openai, azure,
glm, qwen incl. voice-clone + audio download, voxcpm, minimax, doubao,
elevenlabs, lemonade) is created with that signal.

A timeout now fails the tool call with TTSRequestTimeoutError (a clear
retryable error) instead of wedging the session; a caller cancel propagates
as the interruption so the runner settles the session as cancelled without
a restart.

Tests: hung-provider simulation rejects at the timeout with the retryable
error; abort mid-flight aborts the captured request signal and surfaces the
interrupted shape; removing the signal wiring makes the abort tests fail
(red), restoring them turns green.

* fix(workbench): PG-mode home listing via owner stages; keep the interrupted terminal course card (#1218)

Finding 1: with server persistence on, listStages resolved to the generic
GET /api/persistence/documents listing, which the capability model
deliberately answers 403 FORBIDDEN_DOCUMENTS for (reads by id, listings
owner-only). The home/workspace library now lists through the owner-scoped
GET /api/stages surface (same anonymous-owner cookie the workbench uses)
when server persistence is enabled; the server-side 403 is untouched.

Finding 2: a run interrupted (session_interrupted) and repaired
(session_resumed) that ends cancelled before agent_end stranded its pending
classroom sightings, so the timeline's terminal card lost the course the
answer produced. session_end (cancelled) now flushes the pending sightings
into the same course card set agent_end paints, before the stopped caption.

* chore(workbench): remove the bookmark concept and the saved-courses drawer (#1219)

* chore(classroom): remove the bookmark ('collected') concept entirely

The stage-meta viewer port introduced a bookmark surface (stage_bookmarks
table, POST /api/bookmarks, the isBookmarked sidecar field, and a
readOnly rule that let a saved course stay editable). The product has no
such concept, so remove it as a closure:

- delete the /api/bookmarks route and the stage_bookmarks table plus its
  query helpers from the persistence bootstrap
- drop isBookmarked from GET /api/stage-meta/[stageId]
- simplify the classroom read-only rule to readOnly = !isOwner across the
  sidecar client, ownership signal, classroom load, stage store and the
  classroom page
- keep publish/unpublish, generation-complete, isOwner and isPublic
  exactly as they were
- update the gate and stage-meta route suites and the README mentions

The workspace rail's Bookmark glyphs and comments describe the upstream
saved-courses (favorites) section, which is driven by isOwner and renders
no collect affordance; they are kept as unrelated homonyms.

* chore(workbench): remove the saved-courses drawer UI

The first pass removed the bookmark data model but kept the rail's
"Saved courses" drawer, judging it a separate surface driven by
`isOwner === false`. The home/workspace listing is owner-scoped, so that
flag can never occur: `allSaved` is permanently empty and the drawer
(plus the collapsed-rail Bookmark mini-button) is a dead affordance.
Remove it: the SavedDrawer component and its mount, the savedOpen /
savedSection state, the allSaved / matchedSaved derivations, the 'saved'
variant of the course-list renderers, the mini Bookmark glyph, the
drawer-only CSS, and the drawer's i18n keys from all 12 locales. The
courses tab is now exactly one folders tree.

The authored/favorites split in workspace-tree.ts goes with it; the tree
module no longer reads `isOwner`. The discovery course type keeps the
field — the shell still reads it for read-only gating.

Upstream has no collect concept; the drawer could only ever render empty
here. The reference implementation HAS this drawer (its favorites come
from its account system), so this removal is a deliberate upstream
product decision, not a fidelity bug.

* fix(workbench): restore the attach entry, add the rail settings entry, pin all three entry points (#1221)

* fix(workbench): restore the composer attach entry by gating it on the live runtime

The AttachButton's rollout probe read a `materialsEnabled` field that this
branch's /api/agent/runtime never answers (the materials routes gate on the
runtime itself, like the stages), so the gate could never pass and the attach
button never rendered — the Pro launch and chat composers showed only the
@-mention and enhance glyphs.

Substitute the field with the runtime's `enabled` value, which IS the upload
action's precondition: POST /api/materials answers 404 whenever it is false,
so the render condition now equals the action precondition (no dead button).

The button's label (`proMode.attach`) is a user-visible string that becomes
visible again; port the reference implementation's own translations verbatim
into the 11 locales that still carried the Chinese copy.

* feat(workbench): add the settings entry to the rail's bottom-left cluster

The reference's rail foot carries a cluster of utilities (its saved-courses
drawer, the language switcher, the display toggle). This branch removed the
drawer — it could only ever render empty here — and the product decision is
to fill that freed spot with the settings entry.

Add a settings trigger to the foot cluster (expanded rail, beside the
language and display toggles, and on the collapsed strip) and mount the
model/provider SettingsDialog in the rail, wired to the trigger. It is the
same dialog the classic home opens from its header pill; the workspace had no
settings entry of its own, so nothing is duplicated within a surface.

* test(workbench): pin the restored upload, attach, and settings entry points

Covers the three restored entry points:

- the courses-tab upload control: rendered beside the course name filter,
  wired to the discovery hook's ZIP import trigger, disabled while an import
  runs, and gated by the same condition as its action (the courses tab);
- the composer attach control: an actual render of AttachButton under both
  probe answers (visible when the runtime says the upload path is live,
  hidden otherwise), its mounts in the launch and chat composers, the
  branch's runtime-field substitution in the probe, and the reference's own
  `proMode.attach` copy in all 12 locales;
- the settings entry: the trigger in the rail's foot cluster (expanded and
  collapsed), beside the language and display toggles, opening the
  SettingsDialog the rail mounts.

* chore(config): the Pro workbench flag implies the MAIC Editor gate (#1223)

A workbench build without the editor toggle has no way to edit a course:
enabling NEXT_PUBLIC_PRO_WORKBENCH_ENABLED while forgetting
NEXT_PUBLIC_MAIC_EDITOR_ENABLED produced exactly that split-brain bundle.
The workbench IS Pro mode, so its flag now implies the editor gate; the
standalone flag remains for deployments that want the classroom editor
without the workbench. Documents both flags in .env.example.

* fix(agent): wake SSE tails and the runner on durable deltas (streaming fidelity) (#1222)

The Pro workbench chat did not stream: the session/owner SSE routes polled
the durable event log on a 5s/30s clock with no wakeup, so message_update
deltas (written at 150ms cadence) reached the browser in poll-sized blocks
and the thinking strip only mounted after the whole reasoning text had
accumulated.

Port the reference's LISTEN/NOTIFY delta path:

- storage: add in-transaction wake hooks (onSessionEventAppended,
  onOwnerEventAppended, onCancelRequested) so a host queues pg_notify in
  the same transaction as the durable append; align readEventsAfterForReplay
  to rank the bounded page so the first delta after the cursor is always
  kept (the live tail can never starve). Bump @openmaic/storage to 0.18.0.
- app: port the process-wide event-notify bus (dedicated LISTEN client,
  self-check probe, reconnect backoff; notify through the storage
  transaction surface), wire the store hooks, subscribe both SSE routes
  before the initial read with the reference's initializing gate, and give
  the runner one {kind:'session'} subscription whose wake runs the cancel
  check and the message drain. Polls stay as the lossy-NOTIFY backstop.
- lifecycle: start/stop the bus from instrumentation.

Tests: storage hook + compaction contract; route wakeup latency; runner
wakeup wiring with a fake agent; bus unit tests; PG contracts proving a
real append wakes the routes and a live SSE route forwards a message_update
on the wakeup, and that a rolled-back append never wakes. Also fix the
pre-existing park-attempt-budget PG test TRUNCATE (missing CASCADE against
newer FK tables).

* fix(storage): asset writes self-deadlocked against pooled PostgreSQL (#1225)

* fix(storage): refuse the non-transactional byte-write deadlock configuration

A byte store whose plain write() runs on its own pooled connection cannot be
invoked from inside a registry write transaction: after the transaction has
claimed the blob-row lock, that write blocks on the lock the transaction just
took while the transaction waits on the write - a self-deadlock PostgreSQL
cannot detect (one side is idle in transaction).

There is no lock-safe ordering for such a writer: bytes must be written after
the row claim (writing before it lets the collector delete the bytes while the
upsert waits), and any second-connection write after the claim is the
deadlock. The configuration is therefore detected and refused:

- AssetByteStore gains writesOutsideRegistryDatabase?: true, declaring that the
  layer's plain byte operations cannot contend for the registry's row locks.
- PgAssetStore refuses put()/replace() up front (and defends coordinatedWrite)
  when the byte store has no writeWith and does not declare the flag, throwing
  a clear configuration error before any row is claimed.
- The collector mirrors the guard on its delete path (deleteWith or a declared
  out-of-registry layer, else a configuration error).
- The object store declares the flag (its out-of-transaction write remains
  legitimate); the in-registry PostgreSQL byte column provides writeWith /
  deleteWith instead.
- Write transactions (put/replace/remove) set SET LOCAL lock_timeout = 30s so
  any future lock-contention variant fails loudly instead of hanging.

Bumps @openmaic/storage to 0.18.0.

* fix(persistence): forward the transactional byte methods through the lazy asset byte-store wrapper

The no-bucket case of lazyAssetByteStore returned a bare { write, read,
delete } and dropped writeWith/readWith even though the underlying
PgAssetByteStore has them. The registry's hasTransactionalWriter duck check
then failed and put() fell back to the byte store's own pooled connection,
which blocks forever on the blob-row lock the registry transaction just took
when the bytes live in the same PostgreSQL - the production self-deadlock.

The no-bucket layer is statically PgAssetByteStore, so its transaction-pinned
methods are forwarded eagerly (typed against the real signatures via
PgForwardedByteStore). The bucket case keeps its lazy-probing semantics: no
transactional writer exists there, the signed-URL method stays absent or lazy
exactly as documented, and the wrapper now declares writesOutsideRegistryDatabase
so the registry may run the plain write inside its transaction.

New tests pin the wrapper's transactional capability red-to-green and assert
put()/resolve() route byte traffic through the transaction-pinned queryable.

* fix(home): cap the generate-prep ingest drain at 3s so Generate never waits the full server budget

The classic home flow's Generate click drained in-flight ingests for the full
15s server budget. Cap the wait at GENERATE_DRAIN_CAP_MS (3000ms, documented as
a UX bound) and reuse the existing timeout fallback: sources that miss the cap
proceed on the legacy byte path and each late-resolving id is released.

* chore(storage): bump to 0.19.0 over the concurrently landed 0.18.0

* fix(agent): bound every tool call with a timeout; never resurrect a cancelled session (#1226)

* fix(agent): bound every tool call with a global timeout and settle it on cancel

A tool await that neither resolves nor rejects wedges the session forever:
the lease keeps heartbeating and the driver never reaches its next cancel
checkpoint. Race every tool execution (in buildAgent) against a hard budget
(OPENMAIC_AGENT_TOOL_TIMEOUT_MS, default 10 min, per-tool overrides for
known long runners) and against the caller's AbortSignal, so even a
signal-ignoring await cannot keep a cancelled session running.

On timeout the call rejects with AgentToolTimeoutError; the agent loop turns
the rejection into a structured error tool-result the agent can retry or
proceed from, and the abort signal is delivered to the tool's in-flight work
through a derived controller. Zombie-tool updates after settlement are
dropped.

* fix(storage): never re-lease a cancel-requested session; settle it as cancelled on claim

The claim scan treated a session with cancel_requested_at set as a normal
claim candidate: after a restart it re-leased the same session for attempt
N+1 and resumed generating despite the pending cancel. claimNextSession now
settles such candidates as cancelled under the claim lock (status cancelled,
attempt reset, lease and cancel request cleared, terminal session_end event
and owner projection) instead of leasing them, then keeps scanning.

Bump @openmaic/storage to 0.18.0.

* docs: takeaway-style 1.0.0 announcement with bilingual guide links

The 1.0.0 head is now a short takeaway block — badge links to the
official user guides (English and Chinese), five one-line highlights,
and pointers into Features and the workbench setup section — instead of
six dense paragraphs. The detailed provider-neutrality and freshness
notes move into the Features workbench section, phrased database-
neutrally (the announcement no longer names a specific database).
Release date corrected to August 27.

* feat(editor): float the insert toolbar in the outer frame with collapse (#1246)

The insert strip was bounded to the slide card, so it could only ever sit on
top of slide content: the card's overflow clipped it and it could not be parked
in the padding beside the slide. Move it into the studio frame the element
picker's panel already roams (CanvasOverlayPortal + the frame selector), so both
canvas overlays share one bounding container and their handles behave the same.
While picking, the strip rises over the picker and goes inert, which is the
z-order CANVAS_OVERLAY_Z already documents.

Add a fold beside the grip: the chevron collapses the strip to that grip row and
back, with the buttons unmounted rather than hidden. The fold is session-local
state owned by EditShell, next to the drag offset, so a surface swap keeps it;
nothing is persisted. Expanding a strip parked at the bottom edge re-clamps
through the same bounds rule the keyboard move uses.

* fix(workbench): show newly created folders in the sidebar without reload (#1254)

* docs(readme): add the release version prefix and drop the opt-in framing

* fix(workbench): single-source the chat gutter so timeline and composer share a left edge (#1255)

The transcript and the composer each established their own column: their own
`px-*` gutter and their own `mx-auto w-full max-w-*` centering wrapper. Equal
padding values were never enough, because the two columns are centered inside
different containing blocks — the transcript's is a scroll container, whose
content box is narrower than the composer footer's by the scrollbar's width:

  transcript text left = pad + (pane - 2*pad - scrollbar - measure) / 2
  composer box  left   = pad + (pane - 2*pad             - measure) / 2

The padding cancels out of the difference and what remains is `-scrollbar/2` at
every padding value, so the transcript sat half a scrollbar to the left of the
composer and tuning the two paddings against each other could not move it.

The column is now established once, by the nearest common ancestor of both
(`chatColumn`), and the scroll viewport and the composer footer are siblings
inside it that add no horizontal inset of their own. The cap carries the gutter
on top of the 760px reading measure, so the text column keeps its width. The
handed-over question row drops the padding that indented it past the agent's
prose; framed rows keep their own inner padding, which is what a card's border
sitting on the column edge means.

* fix(workbench): lock pane-embedded classroom to edit mode (#1256)

The workspace right pane painted the full learning chrome — speed control,
play button, learner avatars, mic bar — for a course the agent had just
created, then flipped to edit once the first scene landed.

resolveStageChromeMode treated playback as the DEFAULT branch for a hosted
classroom, so every shortfall fell into it: a course whose tab opens at
stage_link time has no scenes yet, so currentSceneId is null and
isHostedSceneEditable is false. A folded pane parked the playback root
behind the fold and cross-faded it out over the pane on unfold, and a
failed editor chunk dropped into playback permanently.

Lock it at the pane instead of defaulting per entry path:

- WorkbenchPanelProvider — the single element that mounts a classroom into
  the workspace — publishes editPinned (visible && !playback). Every entry
  path passes through it, so none of them decides.
- The hosted resolution can no longer degrade to playback. Start Learning
  (workbenchLearning, new input, split out from pane visibility) is the one
  door; everything else resolves between the neutral loading shell and edit.
- Stage's chrome dispatch is exhaustive on chromeMode, so the playback root
  is no longer the else-branch of a condition about the current scene.

No flicker: chromeMode is resolved during render, and preloadEditor now
answers synchronously (isEditorPreloaded) so a remount with the chunk
already registered paints edit on the first frame. A failed import is no
longer cached forever, so the lock cannot strand the pane.

Standalone classrooms keep their stored mode unchanged.

wyuc 97ceb11a14 fix(storage): asset writes self-deadlock against pooled PostgreSQL (#1227)
* fix(storage): refuse the non-transactional byte-write deadlock configuration

A byte store whose plain write() runs on its own pooled connection cannot be
invoked from inside a registry write transaction: after the transaction has
claimed the blob-row lock, that write blocks on the lock the transaction just
took while the transaction waits on the write - a self-deadlock PostgreSQL
cannot detect (one side is idle in transaction).

There is no lock-safe ordering for such a writer: bytes must be written after
the row claim (writing before it lets the collector delete the bytes while the
upsert waits), and any second-connection write after the claim is the
deadlock. The configuration is therefore detected and refused:

- AssetByteStore gains writesOutsideRegistryDatabase?: true, declaring that the
  layer's plain byte operations cannot contend for the registry's row locks.
- PgAssetStore refuses put()/replace() up front (and defends coordinatedWrite)
  when the byte store has no writeWith and does not declare the flag, throwing
  a clear configuration error before any row is claimed.
- The collector mirrors the guard on its delete path (deleteWith or a declared
  out-of-registry layer, else a configuration error).
- The object store declares the flag (its out-of-transaction write remains
  legitimate); the in-registry PostgreSQL byte column provides writeWith /
  deleteWith instead.
- Write transactions (put/replace/remove) set SET LOCAL lock_timeout = 30s so
  any future lock-contention variant fails loudly instead of hanging.

Bumps @openmaic/storage to 0.5.0.

* fix(persistence): forward the transactional byte methods through the lazy asset byte-store wrapper

The no-bucket case of lazyAssetByteStore returned a bare { write, read,
delete } and dropped writeWith/readWith even though the underlying
PgAssetByteStore has them. The registry's hasTransactionalWriter duck check
then failed and put() fell back to the byte store's own pooled connection,
which blocks forever on the blob-row lock the registry transaction just took
when the bytes live in the same PostgreSQL - the production self-deadlock.

The no-bucket layer is statically PgAssetByteStore, so its transaction-pinned
methods are forwarded eagerly (typed against the real signatures via
PgForwardedByteStore). The bucket case keeps its lazy-probing semantics: no
transactional writer exists there, the signed-URL method stays absent or lazy
exactly as documented, and the wrapper now declares writesOutsideRegistryDatabase
so the registry may run the plain write inside its transaction.

New tests pin the wrapper's transactional capability red-to-green and assert
put()/resolve() route byte traffic through the transaction-pinned queryable.

* test(providers): reconcile the neutrality guard with current main and this fix

Two changes that were each green alone broke together on main: the
provider audit removed the lib/storage barrel and types entry points
and reshaped provider references while the guard still pinned the old
file list and counts. Point the file list at the surviving
lib/storage/client.ts, drop the satisfied sora debt, and update the
extract-document mineru count. The asset-byte-store pg count grows
because the wrapper now forwards the transactional byte methods of the
concrete store, which necessarily names it.

wyuc 98904c1c5d fix(providers): three silent-behavior fixes from the provider audit (#1196)
* fix(extract): fail loudly instead of silently falling back to MinerU Cloud

A request that selects the self-hosted MinerU extractor without a
configured base URL used to fall back to MinerU Cloud whenever a cloud
API key was available, sending documents to a third party without the
operator's knowledge. The cloud fallback now requires an explicit
operator opt-in (ALLOW_MINERU_CLOUD_FALLBACK, default off, documented
in .env.example); otherwise the route answers a 422 that names what was
configured (self-hosted MinerU) and what was unavailable (its base
URL), and points at both remedies.

* fix(media): remove the selectable video provider that has no adapter

The Sora entry in the video provider catalog could be selected in the
settings UI and server config, but had no connectivity or generation
dispatch case, so choosing it failed only at execution time. A catalog
entry that cannot execute is worse than an absent one: the entry, its
type-union member, UI names/icons, store defaults, and the VIDEO_SORA
env mapping are removed. A new catalog test pins that every selectable
video provider dispatches to its own adapter in both switches.

* fix(storage): delete the obsolete no-op storage provider abstraction

getStorageProvider() unconditionally returned a NoopStorageProvider and
the module swallowed every operation into silence, so any caller
believing it had storage got neither bytes nor an error. No real caller
exists anywhere in the repo (only lib/storage/client.ts, a separate
module with a documented null contract and a live caller, remains). The
dead entry point, its type file, and the no-op provider are deleted; a
test pins the removal and that the real client upload helper is kept.

parseModelString is reachable with request-controlled strings, so warning
there lets clients drive log volume and grow the dedupe set without bound;
the warning now fires only from boot-time validation of config-derived

wyuc 4a9f906a13 feat(media): resolve image, video, and ASR models from server config (#1175)
* feat(media): resolve image, video, and ASR models from server config

The image generation chain never consulted the server-side
IMAGE_<PREFIX>_MODELS config: the route only forwarded the client
x-image-model header and each adapter silently fell back to a hardcoded
vendor default, so a managed provider could generate with a model the
operator never chose. The provider itself also defaulted to a hardcoded
vendor id when the client sent no preference.

- Add resolveImageModel / resolveVideoModel / resolveASRModel and
  resolveServerImageProviderId / resolveServerVideoProviderId to the
  server provider config, mirroring how TTS already resolves
  server-managed settings.
- Routes resolve provider and model server-side when the client sends
  no preference and fail loud with a clear 400 when nothing resolves;
  no more hardcoded vendor defaults.
- Adapters require an explicit model via requireModel; connectivity
  probes keep a fixed probe payload since they are auth handshakes,
  not user-facing generation.
- Tests cover the resolver precedence and the fail-loud paths.

* fix(media): align model resolution semantics across capabilities

resolveImageModel and resolveASRModel let the server pin win
unconditionally, while resolveVideoModel implements allowlist semantics
(client choice wins when it is in the pinned list, otherwise the first
pinned entry). Align image and ASR to the video allowlist semantics so a
client picking any server-pinned model is honored, and update the
resolver docstrings and tests to pin the aligned behavior for all three
capabilities.

The classroom media path has no client model and no HTTP response to
fail loud with: it now falls back to the first catalog model when the
operator pins no _MODELS list, so key-only deployments keep generating
media instead of silently skipping every element via the adapter's
requireModel backstop.

* feat(export): download narration script as Markdown or Word-compatible .doc

Adds two export-menu entries that download the classroom's TTS narration
text (SpeechAction.text per scene) as a local document for lesson prep,
closing #413. The .doc is a minimal HTML document with the Word MIME type
so no new runtime dependency is introduced; .md is the portable plain-text
sibling. Scenes without speech are omitted, HTML is escaped in the .doc
path, and file names are sanitized.

Reads stage store state at click time instead of subscribing per render,
drops unobservable exporting state (the handler is synchronous and the

unnecessary.

- Skip whitespace-only speech text when collecting scene scripts, so a
  blank course cannot download a heading-only document with a success toast
- Trim and filter empty paragraphs in the .doc serializer to match the
  markdown path
- Strip only dangerous control ranges in the filename sanitizer so emoji
  and ZWJ sequences survive (the broad \p{C} class was splitting surrogate
  pairs)
- Add unit tests for whitespace-only speech, HTML paragraph normalization,
  the <br> branch, emoji-preserving filenames, control-char stripping, and
  markdown whitespace filtering

Co-authored-by: CommandCodeBot <noreply@commandcode.ai>

* fix(export): address review feedback on narration script export

- Decouple the export menu trigger from full media-readiness gating:
  script export (.doc/.md) now stays usable while media generation is
  still pending. PPTX/Resource Pack/ZIP/Video items keep the existing
  media-dependent gate, now with visible disabled state and a tooltip
  explaining why.
- Document the HTML-as-.doc format as a deliberate zero-dependency
  tradeoff (not an oversight) directly above buildDocHtml.
- Sanitize scene/stage titles before they're interpolated into
  Markdown headings, so embedded newlines or leading # runs can't
  inject extra headings or corrupt document structure.
- Localize the "Slide N" fallback label via the i18n system instead of
  hardcoding English, adding export.slideFallback (plus export.textOnly
  and export.mediaPending for the new UI states) across all 12 locales.

Addresses review from @wyuc on PR #1144.

* refactor(export): dedupe export-readiness derivation in header controls

canExport already implies canExportText once it ANDs the media-readiness
check on top, so the trigger's title/aria-label/readiness ternaries had two
independent copies of the same 3-way branch drifting apart. Derive canExport
from canExportText, and share exportReady/exportLabel between the button's
disabled, className, title, and aria-label props.

* fix(export): escape leading # in markdown headings instead of deleting it

Two issues found in code review: (1) a leading newline could shield a
leading # from the strip regex, then trim() would re-expose it unescaped
-- a real order-of-operations bug; (2) unconditionally deleting the
leading # run silently mangled legitimate titles like "#1 Introduction".
Escaping (\#) instead of stripping fixes both: content is preserved and
the character can no longer be mistaken for heading syntax, regardless
of what precedes it.

wyucand杨慎 e96e2fbf7a feat(dsl): standardize the asset manifest and converge the export paths (#1007 part 3) (#1117)
* feat(dsl): standardize the document asset manifest

Add asset-manifest.ts to @openmaic/dsl: the canonical AssetManifestEntry
shape (ref, kind, and byteSize/mimeType/duration/voice/prompt metadata
where available) plus enumerateAssetManifest, the pure document-to-manifest
enumeration. An entry's ref is the reference exactly as the document holds
it -- the manifest is the id-based reference enumeration with metadata,
not a content hash and not a resolution result. The traversal walks the
stage whiteboard, each scene's canvas/whiteboards/speech actions, and the
stage video-manifest keys in document order, with logical-owner reference
counts that match the accounting duplication-safe replacement uses.

This settles the media-ref + asset-manifest schema question (#779 open
question 4) on the side the asset-pool RFC already implied: the schema is
a function of the id semantics decided there. The type lives in the dsl
rather than a new @openmaic/exporter package because the enumeration is
pure over document types the dsl already owns (Stage/Scene/Slide/Action),
so a separate package would add a published artifact and release-workflow
surface without adding a capability; the storage contract comment now
points at the module.

Refs #1007

* refactor(export): drive the classroom ZIP from the asset manifest

collectMediaFiles used to scan the whole mediaFiles table for the stage,
so any row the document no longer references -- an orphan left by an edit
or a superseded regeneration -- rode along into the archive. Both ZIP
collectors now take their reference sets from the standardized asset
manifest (buildStageAssetManifest wraps the dsl enumeration with the
compatibility rows' metadata): only referenced assets are archived, and a
referenced asset whose bytes exist only in the pool is still collected via
a synthesized record. Byte resolution is unchanged: pool first through
resolveStoredBytes / resolveAudioBlob, with the compatibility row kept as
the legacy byte fallback and as the metadata source.

mediaIndex is now a serialized view of the manifest, and the missing-audio
report derives from the manifest's audio entries instead of a second
action walk. The audioRef mapping and the legacy audioUrl fetch path
(collectLegacyAudioForExport) are untouched.

Refs #1007

* refactor(video-export): take the timeline's reference sets from the manifest

createVideoTimelineDeps scanned the whole mediaFiles table for the stage
and derived its audio id set from its own action walk -- a third,
independent answer to "which media does this course use?". Both record
loads now key off the standardized asset manifest: media rows are read per
manifest ref by compound key instead of by table scan, and the audio id
set is the manifest's audio entries. Orphan rows were never reachable
through the scene-scoped elementId-to-mediaRef bridge; now they are not
even read.

The bridge itself is untouched: element ids recur across scenes, so the
elementId-to-mediaRef mapping stays scoped per scene, and the legacy
audioUrl fallback keeps its own action walk because a URL is not a
manifest ref. AssetPlan remains the video IR's view of the same
references.

Refs #1007

* refactor(export): resolve PPTX media through the shared resolver only

Each PPTX element branch carried its own resolution chain: a task-state
renderable-URL lookup first, then -- gated on the legacy placeholder
predicate -- a stored-bytes override, with the poster block repeating the
pattern. One helper now owns resolution for backgrounds, images, video /
audio sources, and posters: opaque refs (allocated ids and legacy
placeholders alike, no placeholder-pattern gate) resolve pool-first
through resolveStoredBytes and embed as data URLs, concrete addresses
resolve through the media state machine and keep the caller's fetch path.
exportMediaResolution and the resolveStoredMediaBlob wrapper fold into
the helper; resolvePptxMediaBinding stays as the state-machine entry the
resolution-surface test matrix drives.

Refs #1007

* refactor(export): retire the export-side Dexie byte fallbacks

Export call sites no longer read bytes off compatibility rows directly.
The ZIP collectors and the video timeline's audio load resolve bytes only
through the shared resolvers (resolveStoredBytes / resolveAudioBlob),
which answer pool-first and keep the compatibility row as their internal
legacy fallback level; the row reads that remain at the call sites supply
metadata (format/duration/voice/mime/size/prompt) only. The rows
themselves stay for legacy and regeneration readers -- what goes is the
export paths' own fallback logic.

One observable tightening: a failed media row (error set, empty
placeholder blob) no longer ships a 0-byte file into the classroom ZIP,
and an evicted row no longer ships its empty local blob; referenced-but-
byteless assets are simply absent from the archive, as they already were
when no row existed.

* test(media): cover the enriched stage asset manifest builder

Pins the join between the pure dsl enumeration and the compatibility

* fix(video-export): widen the deps stage input for the manifest enumeration

enumerateAssetManifest reads the stage's whiteboard and videoManifest, so
createVideoTimelineDeps declares them on its input instead of the bare id;

applies the repo prettier formatting to the files this branch touched.

* fix(dsl): enumerate slide audio elements in the asset manifest

Slide audio elements carry their own src, and the manifest skipped

The audio slot maps to kind 'audio' alongside narration ids.

Refs #1007

* fix(media): harden ref-keyed lookups against prototype-named asset refs

AssetRef is an unconstrained string alias, so a media reference can legitimately be "__proto__", "constructor", or any other Object.prototype member. Plain objects keyed by such refs silently drop assignments or answer lookups with the prototype object, which rewrite paths then accept as a mapped id.

Convert the remaining ref-keyed lookup tables introduced by the export convergence to prototype-safe structures: the classroom import media/poster alias maps and the legacy-conversion video-manifest reconstruction now use Map / null-prototype containers with explicit membership checks, and every consumed value is validated as a string before it is written into a src / mediaRef / audioId slot. The shared media-task lookup receives the same treatment: one centralized own-property-checked lookupMediaTask now serves the stored-bytes resolver, the PPTX embeddable-src path, the video collection path, and the element/background task resolution, so a prototype-named placeholderRef can no longer hide a re-keyed task from the fallback chain.

Adversarial tests drive "__proto__" and "constructor" refs through the import round trip, the PPTX fallback path, the legacy conversion commit path, and the media-task fallback end to end, including a buildPptxBlob regression with a task re-keyed to an allocated id while retaining a prototype-named placeholderRef.

* refactor(export): derive consumer refs from manifest

* fix(export): sanitize classroom archive extensions

* fix(video-export): preserve narration speech order

* fix(export): enforce kind-coherent archive media

* fix(export): define media coherence boundary

* fix(export): carry task-owned poster binding for PPTX export

A video element with no explicit poster falls back to its media task's
generated poster URL, but resolveVideoMediaForElement left posterTask
undefined for that case, so the PPTX manifest guard saw a foreign URL
with no task-ownership exemption and dropped the video element instead
of using the established runtime poster fallback.

Carry the poster task binding whenever the task poster is the effective
poster: the task-owned URL then satisfies the guard's objectUrl
exemption end to end. A concrete explicit element poster still stays
element-owned and never borrows the binding, and the guard's foreign-ref
rejection is preserved (and exported as a directly testable predicate).

Coverage: an element with no poster plus a task-provided poster embeds
the task poster as the PPTX cover (red at the pre-fix head, green now),
and a genuinely unrelated URL with no task ownership is still rejected
by the guard.

* fix(export): preserve legacy narration source refs in the media index

The explicit sourceRef contract was partial: primary audio and generated
media entries carried it, but legacy URL narration serialized no source
ref. The legacy URL itself is the natural source ref — it is known at
fetch time — so wire it through the collected blob into the mediaIndex
entry. Import already registers serialized sourceRefs as aliases, so the
URL now round-trips as an explicit mapping instead of being reconstructed
only from the action's audioRef.

Poster siblings are deliberately NOT given their own mediaIndex entry:
a sibling poster (media/asset-<n>.poster.<ext>) is a legacy byte copy
written from the video record and is not an independently referenced
document asset — when the poster is a real document asset it already has
its own indexed entry with a sourceRef, and import reconstructs the
sibling by path derivation from its parent video entry, reusing the
poster's own indexed allocation when one exists. The PR description is
narrowed to match; corrected paragraph:

"Archive names never interpolate refs — sequential safe paths
(media/asset-<n>.<ext>, audio/audio-<n>.<ext>) with the original ref
preserved through an explicit sourceRef mapping on every independently
indexed media entry: generated media assets, poster assets, primary
narration, and legacy URL narration (the legacy URL itself is the
entry's sourceRef). Extensions are allowlisted per kind. The one
exception is the legacy sibling poster byte copy
(media/asset-<n>.poster.<ext>, written next to its video when the video
record still carries the pre-pool poster bytes): it is not an
independently referenced document asset, so it has no mediaIndex entry
or sourceRef of its own — its identity is derivable from its parent
video entry (same index), and import reconstructs it by sibling-path
derivation from that video entry, reusing the poster's own indexed
allocation when one exists."

wyuc 1a151c4a49 refactor(media): share one stored-bytes resolver across export paths (#1007 part 3a) (#1116)
* refactor(media): share one stored-bytes resolver across export paths

The classroom ZIP, PPTX, and video exports each re-implemented the same
pool-first byte resolution with a Dexie compatibility-row fallback and a
task-URL fallback. resolveStoredBytes in lib/media/resolve-stored-bytes.ts
now owns the chain, with the per-path differences (which levels run, fetch
validation strictness, state-machine gating) as explicit options. The
record-id to ref mapping moves alongside it as mediaRefFromRecordId.

Intended as a behavior-preserving extraction: same bytes, same fallback
order, same error handling. Cross-review found two places where this commit
did not achieve that, both repaired later on this branch -- it moved a
supplied row's `error` verdict past the pool await (restored by the snapshot
fix) and dereferenced `record.blob` unguarded (guarded by the option-surface
fix). See the PR description for the resulting divergence from main, which
is stated rather than claimed away.

Refs #1007

* fix(media): make the resolver's option surface mean what it documents

Cross-review round 1 surfaced the same class of defect from both reviewers:
options and docstrings that promise more than the code does.

- `taskUrlFallback` was inert without `resolutionGating`. The task lookup was
  derived from the gating flag alone, so the final level resolved with no task
  and always returned null. The lookup now runs whenever either concern needs
  it, while the gated levels still read it only when gating is on -- so no
  current caller's behavior changes, and the pre-refactor callers' own
  unconditional lookup is restored.
- `compatRowBytes` dereferenced `record.blob.size` unguarded, which broke the
  module's "never throws" contract and lost the guard the pre-refactor video
  path had (`blob && blob.size > 0`). A row that lost its blob now falls
  through to the next byte source.
- `loadCompatRow` (requires `stageId`) and `compatRowCdnFallback` (needs a row)
  now state their dependencies instead of silently doing nothing.

Six tests pin the behavior; each fix was mutation-checked (reverting the task
decoupling reds one, reverting the blob guard reds two).

* test(media): pin the resolver behavior the round-2 review found unpinned

Round 2 produced no behavior findings from either reviewer; every finding was
a test that would still pass with the behavior broken. Six cases close them.

Mutation-verified -- reverting the code each covers reddens it:

- Gating suppresses stale POOL and row bytes, not only the final level
  (removing either gate reds it).
- With gating off the compatibility row is still accepted while a task is
  generating. This is the discriminator for keeping `gate` separate from
  `task`: leaking the task into the gated levels reds it.
- A zero-length row blob falls through to the CDN source when enabled, and
  never reaches it when not (breaking `compatRowCdnFallback` in either
  direction reds one of the two).
- The effective ref comes from a supplied row's compound id, not the ref the
  caller passed (dropping the derivation reds it).
- The classroom ZIP still ships a non-OK pool response body -- the rebase
  conflict resolution that was correct but untested (tightening `requireOk`
  reds it).

Not mutation-verified, and marked as such in the file: "accepts pool bytes
with gating off" documents the pool level's unconditional branch but survives
every single-edit revert of the task/gate separation, because that level
branches on the option rather than on the gate. It is kept as documentation,
not as a sentinel.

* fix(media): snapshot a supplied row's error verdict before the pool await

Round 4 of cross-review found a divergence three rounds of level-by-level
comparison had missed. The pre-refactor video path computed
`usableRecord = record && !record.error` BEFORE awaiting the pool; the
extraction moved that test after the await. The supplied row is a live
object, so an `error` set (or cleared) while the pool lookup was pending
changed which bytes the export shipped.

The verdict is now taken where the caller took it, and -- the part the first
attempt at this fix got wrong -- it is not re-derived afterwards:
snapshotting only the reference still re-read `error` off the live object at
the later check. A row this function loads itself is still judged when it is
read, after the pool miss, because that read did not exist any earlier.

This was the last value read at a different point in the SEQUENCE than the
code it replaced. What remains is scheduling, not sequence: the row's `blob`
and `ossKey` are still read after the pool as they were on main, only one
microtask later. The PR description states that, and no writer in the repo
mutates a row in place across that window.

Two tests pin both directions (an error landing mid-lookup, and one
clearing); judging the supplied row after the await reds both.

* test(media): commit the frozen-base differential harness (F-1116-001)

The PR description claimed a differential comparison against the verbatim
pre-refactor implementations, but that comparison was run out of tree and
never committed, so no reviewer could re-run it. A claim that cannot be
reproduced is not evidence.

The three implementations are now reproduced verbatim as they stand at the
merge base -- still identical to main, since nothing between the two touched
them -- and driven side by side with the current helper under each call
site's real option set, over a declared matrix of ref shapes, task states,
pool outcomes, fetch outcomes, record shapes, and stage scoping. Every
combination compares the outcome (bytes, null, or the thrown type), blob
identity by reference, and the ordered lease / Dexie / fetch sequence
including arguments.

Absolute microtask offsets are not compared, for the reason the description
gives: the extraction moves later operations one or two ticks while leaving
the sequence, the arguments, and the results alone.

The blob-less PPTX row is the only permitted divergence, and the harness
pins where it may occur rather than merely tolerating it: every divergent
combination must be that row with a stage, and the count must equal the
combinations that actually reach the row -- all of them except the ones
where the frozen path returns pooled bytes first.

The harness bites: dropping the zero-byte rejection reds ZIP and video,
dropping the response.ok check reds PPTX and video, and dropping the
compound-id ref derivation reds video. Its scope is documented in the file --
option combinations no call site uses, and state that mutates mid-await, are
covered by the targeted tests instead.

wyuc e15780835a feat(media): convert legacy references to allocated asset ids (#1101)
Lands epic #1007 part 2(c): the app-side reference converter, the `audioUrl`
removal, and the `DSL_VERSION` bump as one delivery unit.

`convertDocumentAssetRefs` walks a loaded document (slide canvases, whiteboards,
video-manifest keys, speech actions) and rewrites legacy handles to allocated
pool ids: placeholders and `audioId`s with local bytes are ingested, a co-present
`audioUrl`/`audioId` pair collapses to one asset, a definitively dead URL
converts to an emptied reference, and a transient failure keeps both handles for
a later retry. Unavailable bytes leave the document untouched for a later open,
and a converted document returns by identity with no writes.

Conversion runs lazily on document open and at fetch time for server-generated
classrooms, with conversion and the first document save sharing the per-stage
document lock: once the document commits it owns every allocation, and every
failure exit rolls its pass ledger back. Legacy URL probes are bounded by a
per-probe timeout and a shared 60-second pass budget.

`SpeechAction.audioUrl` is removed from the DSL and every consumer reads the
converted shape; the server classroom generator keeps its derived-id + serving-URL
pair as an explicitly typed pre-conversion transport, consumed before persistence.
`DSL_VERSION` becomes 0.2.0 with the first real ladder entry, and
`@openmaic/dsl` goes to 0.9.0 per the release rule.

Deferred follow-ups are tracked in #1129: production principal derivation with
document/asset ownership aligned, conditional document writes, and hoisting the
aggregate probe budget into the export and video-timeline paths.

wyucand杨慎 0a10af11cf feat(storage): opt-in indirect asset byte egress (#1007) (#1100)
* feat(storage): add opt-in indirect asset byte egress

A deployment can now opt an asset byte GET into a 302 to a short-lived
signed URL when the byte layer can sign. It is off by default, and
byte-for-byte unchanged when off. The byte layer gains an optional
signReadUrl capability; S3AssetByteStore implements it through the new
optional @aws-sdk/s3-request-presigner peer, resolved lazily exactly
like the client SDK, with a signer seam mirroring the commands seam so
tests can bind doubles. The signed URL pins the contract's response
headers -- the media type after the renderable allowlist, the fixed
disposition, and the no-store cache posture -- via S3 response-header
overrides. PgAssetStore mints the URL from the same ownership-checked
transactional read a direct resolve performs, so authorization still
runs per read before any URL exists, and a store whose byte layer
cannot sign falls back to direct bytes. The contract documents the
shape and the disclosure tradeoff: a Location into a hash-keyed byte
layer names the content hash, so deployments that need the
no-disclosure property keep direct egress.

Refs #1007

* feat(app): wire ASSET_BYTE_EGRESS into the persistence route

ASSET_BYTE_EGRESS=redirect opts asset byte GETs into the storage
package's indirect egress; unset, direct, or an unrecognized value
keeps the default byte-for-byte behavior, with a warning for the
unrecognized case. The lazy byte-store wrapper now forwards
signReadUrl and answers undefined when the resolved layer has no
signer, so the PostgreSQL byte column degrades to direct bytes and
the S3 layer signs without the wrapper knowing which it holds. The
collector path is untouched: it builds its byte store through
createAssetByteStore as before and only ever calls delete.

Refs #1007

* fix(storage): let the packaged client survive redirect egress

Cross-review round 1 on the indirect byte egress change found two
problems.

A byte response that followed a redirect carries the pinned content
type but no X-Asset-Revision, and HttpAssetStore required both from
the same response, so every cold resolve under redirect egress failed
MALFORMED_RESPONSE. The client now detects the shape once -- a
redirected byte response with no revision -- latches it, and probes
HEAD before each cold GET from then on, taking the label from the
probe. The probe predates the download on purpose: a replacement in
between labels newer bytes with an older revision, which the next
revalidation detects and corrects, while the reverse order could pin
stale bytes under a fresh revision with no signal to repair it. The
probe doubles as the miss check, so a redirect-mode miss costs no
download. The direct path is byte-for-byte unchanged; the one double
download per client lifetime on first contact is documented in the
contract, which gains the client-side paragraph this behavior
implements.

signedUrlTtlSeconds also accepted lifetimes beyond the seven-day
SigV4 presigning maximum, minting redirects the object store would
reject. The option is now capped at construction.

Refs #1007

* fix(storage): cap signed URL lifetime below the reclamation grace

A signed URL whose lifetime exceeds the collector grace period can
outlive its object: the last reference goes, the grace elapses, the
collector deletes the object, and the still-valid URL errors at the
object store. The previous ceiling -- the seven-day SigV4 maximum --
made that window days wide against the one-hour default grace. The
cap is now fifteen minutes, and the contract text states both the
ceiling and the rule for deployments that shorten their grace.

Refs #1007

* fix(storage): decline signing when the optional presigner is absent

An unresolvable @aws-sdk/s3-request-presigner made signReadUrl throw,
which the registry surfaced as a failed asset read -- a 500 for a
deployment whose only fault is a missing optional peer. The contract's
answer for a byte layer that cannot sign is the capability fallback:
return undefined and let the caller serve the bytes directly. Signing
errors from a resolved signer still fail loud; only the missing
capability declines.

Refs #1007

* fix(storage): answer redirect egress as a descriptor to asking clients

Following a 302 is not header-neutral: the platform fetch forwards the
original request's headers to the object store's origin, stripping only
Authorization, so a deployment whose credential travels in a custom
header would hand it to the object store -- and the preflight the
forwarded custom headers provoke commonly fails there besides. This
replaces the latch-and-probe client shape with an explicit one: the
client sends X-Asset-Egress: descriptor on every byte GET, a
redirect-egress server answers 200 with a JSON { url, revision } body
instead of a Location, and the client fetches the signed URL with no
deployment headers at all. The revision comes from the descriptor, so
the probe-first ordering and its one wasted download are gone too. The
302 remains the answer for consumers that did not ask; the descriptor
response is marked by its own header so a JSON-media asset can never
parse as one.

Refs #1007

* fix(storage): negotiate the descriptor through Accept, not a custom header

A custom X-Asset-Egress request header is not CORS-safelisted, so every
byte GET to a cross-origin server became a preflighted request -- a
regression for direct-egress deployments that never opted into
anything, against servers with no reason to allow the header. The
negotiation now rides Accept with a vendor media type, which is
safelisted and costs no preflight, and the descriptor answer is
identified by that media type as its Content-Type rather than by a
marker header.

Refs #1007

* fix(storage): sign outside the registry transaction and reserve the descriptor type

Two review findings on the indirect egress path.

resolveIndirect awaited the signer inside the coordinated read, but a
signer on refreshable credentials can wait on the network, and a
database connection plus the blob row's FOR SHARE lock would be held
across that delay. The read now closes first -- the lock still puts
the hash, label and revision in one snapshot -- and signing runs
afterwards, which cannot observe anything the read did not.

The descriptor media type is also reserved from renderableTypes: the
client identifies a descriptor answer by that exact Content-Type, and
an allowlisted asset served with it would be misread as a descriptor
and fail MALFORMED_RESPONSE. The handler now rejects the configuration
at construction, and the contract states the reservation.

Refs #1007

* fix(storage): ship the signing deps and negotiate without ambiguity

Three review findings on the indirect egress path.

The app now declares @aws-sdk/client-s3 and
@aws-sdk/s3-request-presigner as runtime dependencies, and the
standalone build force-includes them for the persistence route: both
are reached through deliberately untraced dynamic imports, so the
shipped image could not resolve them, and a deployment opting into S3
or redirect egress would have found the capability silently absent.

The descriptor negotiation matches exactly on both sides: the client
compares the Content-Type essence, so a longer media type that merely
begins with the reserved value still serves as bytes, and the server
parses Accept media ranges, so a descriptor range sent with q=0
selects the redirect instead of the descriptor it explicitly rejects.

Refs #1007

* fix(app): refuse redirect egress when the collection grace is shorter

A signed URL must never outlive its object: with the handler's
60-second default lifetime, a deployment that sets
ASSET_COLLECTION_GRACE_MS below ten minutes lets the collector delete
an object while a URL minted against it is still valid. The route now
refuses the combination at handler initialization, naming both
variables -- a deterministic misconfiguration, loud at startup rather
than silent at read time.

Refs #1007

* fix(app): ship the signing SDKs without loading them

Two findings on the standalone deployment of redirect egress.

The outputFileTracingIncludes globs did not follow pnpm's scoped
symlinks, so the standalone image carried neither AWS package and both
S3 mode and redirect egress could not resolve their SDK at runtime.
The packages are now server-external and referenced from literal --
but never called -- dynamic import thunks in the persistence byte-store
wiring, which gets them traced into the image while module resolution
still happens only on first S3 use. Verified against a local
standalone build: node_modules/@aws-sdk now contains both packages,
and the route tests that pin the never-resolve-unless-configured
discipline still pass.

Media type comparisons are also case-insensitive now, as HTTP
requires, on both the Accept parse and the descriptor recognition.

Refs #1007

* fix(app): treat an empty collection grace as unset

Number('') is 0, so a present-but-empty ASSET_COLLECTION_GRACE_MS
failed the redirect-egress coordination check and took persistence
down with it, while the collector's own parsing reads the same value
as the one-hour default. The check now trims and treats empty as
unset, matching durationEnv.

Refs #1007

* fix(storage): accept bytes too, omit signing on the known-PG wrapper, state the full tradeoff

Three review findings.

The client's descriptor request now advertises both representations --
the vendor descriptor type preferred, */* accepted -- so a strict
content-negotiating layer can never answer 406 to a client that does
in fact consume plain bytes.

The lazy byte-store wrapper no longer advertises signReadUrl when no
bucket is configured: the layer is known to be PostgreSQL at
construction, and carrying the method made resolveIndirect take its
ownership query and blob-row lock just to decline, then repeat them
in resolve, on every cold GET. With a bucket configured the lazy
validation is preserved and the wrapper still declines when the
resolved layer cannot sign.

And the contract's disclosure tradeoff now states the second edge:
object-store GETs carry ETag and Last-Modified, response overrides
cannot strip them, and because deduplicated PUTs rewrite the
hash-keyed object, Last-Modified moves when another principal
re-uploads the same bytes -- shared-object write timing, beyond byte
equality. Deployments for whom that signal is sensitive must keep
direct egress.

Refs #1007

* fix(app): degrade on bad grace, share the ttl invariant, cover the real boundary

The latest review round, four findings.

A misconfigured ASSET_COLLECTION_GRACE_MS now degrades redirect
egress to direct with a warning instead of failing the shared
handler's initialization -- the asset backend is optional, and its
misconfiguration must never take document and runtime traffic down.

The package exports assertSignedUrlTtlWithinGrace so a deployment
wiring the handler and the collector separately validates the
invariant once at its own boundary: the handler caps the lifetime,
but only the deployment knows both numbers.

The contract states that nosniff does not survive the redirect --
response-header overrides cannot set it -- and why the client-minted
blob makes that safe for conforming clients.

And the route gains a real-boundary test: the Fetch<->Node adapter,
the real createStorageHttpHandler, and the egress wiring, exercised
with an actual byte GET through the composed stack instead of mocks.

Refs #1007

* fix(storage): make the unsafe egress configuration unrepresentable

Three findings on the indirect egress path, all resolved by moving a
rule into a place where it cannot be bypassed rather than by adding a
check a consumer has to remember.

The grace/TTL invariant now lives in the option shape. byteEgress takes
'direct' or { mode: 'redirect', collectionGraceMs, signedUrlTtlSeconds? },
so enabling indirect egress without declaring the reclamation window it
lives inside no longer type-checks, and the handler validates both
numbers at construction. The flat signedUrlTtlSeconds option, its
cross-field "requires byteEgress redirect" check, and the standalone
900-second cap as the only guard all go away; the ceiling stays, but
alongside the ratio rather than in place of it. This is what the earlier
exported assertSignedUrlTtlWithinGrace could not do -- it protected only
consumers who called it -- and it costs nothing in compatibility because
the option is new in this branch. The app resolves the grace through one
shared parser with the collector, so the number the handler checks is the
number the collector runs with.

A signed URL whose object is gone is now a miss. The client maps a 404
from the byte fetch to ASSET_NOT_FOUND, matching the direct path: the
entry was owned and readable when the URL was minted, so a reclaimed
object is the same physical state the direct read reports as a miss, and
what a read means must not depend on the deployment's egress setting.
Signing still does not probe for the object -- that would restore the
round trip this feature removes and make the mint's price vary with prior
presence -- so the contract instead requires the byte layer to answer 404
for an absent object, and states that S3 needs s3:ListBucket to do so.

Route coverage now spans the whole egress matrix through the real
composed handler rather than only the direct case: 302 for a consumer
that did not ask, descriptor for one that did, direct bytes when the
byte layer declines to sign, and direct bytes when a short grace degraded
the configured mode.

Refs #1007

* feat(storage): forward byte egress options through reference server

* fix(storage): fail closed on redirects and unconfirmed 404s in indirect byte egress

A signed-fetch 404 now maps to a miss only when the object store's XML
body declares NoSuchKey; every other 404 from the signed fetch fails loud,
so a wrong bucket, access point, or endpoint can no longer make a live
asset read as absent. The descriptor byte GET is sent with redirect:
'manual' and any 3xx answer is treated as an error, so a server that
ignores the descriptor negotiation can never forward the deployment's
custom credential headers to a redirect target.

The ASSET_BYTE_EGRESS switch is now documented in .env.example and the
server-persistence deployment section, together with the object-store CORS
and s3:ListBucket prerequisites it requires, and the asset descriptor
media type is exported from the package root and the asset/http subpath.
