feat(choreography): shared orchestration spec in lib/choreography (#863) (#890) * feat(choreography): shared orchestration spec in lib/choreography (#863) Introduce lib/choreography/ as the single source of truth for the orchestration semantics a faithful classroom-video exporter needs from playback, so the app runtime and the exporter interpret one spec instead of each re-implementing (and silently drifting from) the other. Kept in lib/ rather than a package: these semantics co-evolve with the playback engine, and the exporter will also live in the app, so both consumers share them via ordinary imports. Purity is machine-enforced by an eslint boundary on lib/choreography/** (blocks @/ host-app paths + react/react-dom/gsap/framer-motion/motion), so the exporter can interpret the spec in a pure Node environment. - timing.ts — timing constants + the deterministic no-audio speech estimate, moved verbatim from the engines. - cursor.ts — resolvePlaybackCursor + EMPTY_SCENE_DWELL, moved from lib/playback/engine-cursor.ts (typed on dsl SceneCore). - timeline.ts — new pure resolveActionTimeline: index-domain -> time-domain expansion (blocking cursor-advance vs fire-and-forget visual duration), keyed off the DSL fire-and-forget partition. - descriptors/— versioned, zod-schema-validated animation descriptors spotlight.v1 + laser.v1 (declarative: property/from/to/ duration/easing; no implementation), pinned to the current overlay components. Behavior-neutral engine refactor: lib/action/engine.ts and lib/playback/engine.ts import from lib/choreography and the local literals are deleted, so the timing dimension now has exactly one copy. The spotlight/laser overlay components still hardcode their animation values (they do not yet READ the descriptors) — tracked in #889. Closes #863 * fix(choreography): address cross-review findings on resolveActionTimeline + descriptors - P1: model implicit whiteboard auto-open — a wb_* mutation on a closed board now prepends a synthetic IMPLICIT_WB_OPEN (WB_OPEN_MS) beat, mirroring the engine's ensureWhiteboardOpen; open state carries across scenes and toggles on wb_open/wb_close (new `whiteboardOpen` option to seed it). - P2: scale real speech audio duration by playbackSpeed too (live path sets AudioPlayer.setPlaybackRate), keeping it in lockstep with the estimate path. - P2: express the spotlight mask relationship in the descriptor model — LayerSchema gains `role` ('content'|'mask') + `maskedBy` (subtract|intersect); spotlight.v1's cutout is now a mask layer the dim layer subtracts, so a non-React consumer reconstructs the cutout instead of a black rect. - P3: wb_clear on an empty board is 0ms (engine early-returns), not wbClearMs(0). Tests: tests/lib/choreography 45 pass (+6); engine regression 28 pass; tsc + lint clean. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(choreography): address final-audit findings on effect lifetime + spotlight descriptor Second cross-review round (fresh-session codex final audit) surfaced three deeper mismatches with live playback: - P1: fire-and-forget effect lifetime is not a flat EFFECT_AUTO_CLEAR_MS. The engine's processNext clears effects at every scene boundary and on completion, and scheduleEffectClear uses one shared timer each new effect resets. Added clampFireAndForgetLifetimes: an effect's visual durationMs is now min(next scene boundary / completion, shared-timer deadline chained through later effects in the same scene). advancesCursorMs (0) is untouched. - P2: spotlight dimness default is 0.5 (executeSpotlight: dimOpacity ?? 0.5; DSL documents 0.5), not the component's unreachable ?? 0.7 fallback. Fixed the descriptor param + test. - P2: model the spotlight wrapper's enter/exit opacity fade (motion.div, no explicit duration → engine default). TrackSchema.durationMs is now optional to express "use the consumer's engine default"; dim layer carries the fade tracks. Tests: tests/lib/choreography 50 pass (+5, incl. boundary-cut / completion-cut / full-lifetime / shared-timer-extension / wrapper-fade); engine regression 28 pass; tsc + lint clean. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(choreography): pin spotlight fade duration + laser dot geometry in descriptors Third cross-review round (codex) flagged two descriptor-completeness gaps that would make a non-Motion consumer (the exporter) diverge from the app: - Spotlight wrapper fade: the enter/exit opacity tracks left durationMs implicit (Motion default). A literal consumer treats a missing duration as instant, so the spotlight would pop on/off. Pinned to Motion's default 300ms tween. - Laser dot geometry: the descriptor captured only tracks, not the dot group's center anchor (translate -50%,-50%) or the rounded-full ring/core. A literal renderer would draw an offset 10px square. Added the static geometry (anchor, borderRadius 9999, ring inset/position) so the shape/position match the app. Also refined the effect-lifetime docstring to cite the app's per-scene engine teardown/completion (the actual clearEffects path) rather than an intra-engine boundary gate that is dead in the single-scene-per-engine configuration. The empty-scene "speech dwell → blank chat bubble" observation is pre-existing behavior: EMPTY_SCENE_DWELL is a verbatim move from lib/playback/engine-cursor.ts (unchanged from origin/main), out of scope for this move-only PR; tracked separately. Tests: tests/lib/choreography 54 pass; engine regression 28 pass; tsc + lint clean. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(choreography): zero-duration for engine-skipped/no-op actions in timeline Fourth cross-review round (codex) flagged two remaining timeline divergences: - Skipped discussions: the engine skips a discussion outright (no timer) when it's already consumed or its agent isn't selected, but the timeline always charged DISCUSSION_TRIGGER_DELAY_MS. Added `isDiscussionSkipped` resolver (runtime-state-dependent, like getVideoDurationMs) → 0ms when skipped. - No-op whiteboard draws: executeWbDrawText (empty content) and executeWbDrawTable (no rows/cols) return before any delay. The timeline now charges 0ms for these determinable-from-the-action no-ops instead of WB_DRAW_MS. (KaTeX-failure / missing-edit-target no-ops depend on runtime state and remain out of scope, consistent with the resolver pattern.) Tests: tests/lib/choreography 56 pass; engine regression 28 pass; tsc + lint clean. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(choreography): exact-5s effect chain break + spotlight dim full-screen geometry Fifth cross-review round (codex), both P2: - Effect chain break at an EXACT 5s boundary: the earlier effect's clear timer is queued before the reading timer that triggers the later effect (same 5000ms delay), so it fires first — the predecessor is cleared at exactly deadlineMs, not extended. Changed the chain guard from `> deadlineMs` to `>= deadlineMs`. - Spotlight dim layer full-screen geometry: the descriptor recorded only fill + mask relation, leaving a literal consumer no way to know the dim rect spans the 0..100 viewport. Added explicit x/y/width/height (100×100 at origin) so the descriptor is self-contained. Tests: tests/lib/choreography 57 pass; tsc + lint clean. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(choreography): no-op wb_edit_code resolver in timeline Sixth cross-review round (codex), one P2: executeWbEditCode returns before its delay when the edit can't apply (missing/non-code target, stale line refs). The timeline always charged WB_EDIT_MS. Added `isEditCodeNoop` resolver (runtime- state-dependent, same pattern as getClearElementCount / isDiscussionSkipped) → 0ms when the caller flags a no-op. Tests: tests/lib/choreography 58 pass; tsc + lint clean. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(choreography): descriptor layer inheritance for nested effect layers Seventh cross-review round (codex), two P2 with one root cause: the flat layers[] model couldn't express a child layer riding a parent's animation (the source nests some layers inside an animated wrapper). Added an `inheritsFrom: {parentId, props}` relation to LayerSchema: - Laser ring + core inheritsFrom the animated `dot` (left/top/opacity), so a literal consumer flies them in/out with the dot instead of leaving them at a static origin while only the dot moves. - Spotlight border inheritsFrom `dim` (opacity), so the outline fades out with the wrapper instead of lingering after the dimming layer disappears. Tests: tests/lib/choreography 60 pass; tsc + lint clean. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(choreography): address review — discussion auto-skip, explicit video policy, import allowlist Human review (wyuc) raised two blocking timing issues + one non-blocking guard: - Discussion dwell (blocking): a non-skipped discussion in unattended playback/export blocks for the trigger delay AND the ProactiveCard's own auto-skip countdown, not just DISCUSSION_TRIGGER_DELAY_MS. Added DISCUSSION_AUTO_SKIP_MS (5000) to the timing spec and charge DISCUSSION_TRIGGER_DELAY_MS + DISCUSSION_AUTO_SKIP_MS. ProactiveCard now reads the same constant (was a hardcoded 5000), so card countdown and timeline can't drift. A `spotlight -> discussion -> speech` timeline now extends the spotlight across the full discussion interval. - play_video (blocking): an unresolved duration no longer silently becomes a 0ms segment (which shifted every later action early). New `onUnresolvedVideoDuration` policy defaults to 'throw' (fail loudly); 'cap' assumes MAX_VIDEO_WAIT_MS, 'zero' opts back into no-dwell explicitly. - Purity guard (non-blocking): turned the lib/choreography boundary into a true import allowlist. Beyond the existing @/… + render-package blocks, it now rejects parent-escape (../…) imports/re-exports, any bare package other than @openmaic/dsl / zod, and dynamic import()/require(). Negative-tested: ../store, a stray bare package, export * from ../playback, and import('react') all fail. Tests: tests/lib/choreography 60 pass; engine regression 28 pass; tsc + lint clean.

chore(packages): publish the @openmaic/* SDK family to npm (#778) (#780) * chore(packages): publish the @openmaic/* SDK family to npm (#778) Prepares the @openmaic/{dsl,renderer,importer} family for its first npm publish, and moves the SDK packages onto the @openmaic scope. Why the scope move: the @maic org name is unavailable on npm (an unscoped `maic` package already holds the name), so @maic/* is not claimable. @openmaic matches the project name, the scope is free, and the repo already ships an @openmaic/docs package — so the SDK family now lines up with that convention. - rename @maic/{dsl,renderer,importer} -> @openmaic/* across packages, the workspace glob, the package dir, and all import sites; lockfile regenerated - renderer: add publishConfig (public, registry.npmjs.org) — was missing, so a scoped publish would default to the wrong registry / restricted access - importer: add a files allowlist (dist, README, LICENSE) and drop the fragile .npmignore blacklist that shipped src; add an exports map so ESM consumers resolve dist/index.js instead of falling back to the .cjs main - all three: add a prepublishOnly build (+ test/typecheck) guard so a publish can never ship a stale or empty dist - add a tag-triggered publish workflow with npm provenance, pinned by name to the three @openmaic packages so the vendored forks (mathml2omml, pptxgenjs) are never published Refs #778, #720 (Phase 1). * fix(packages): address cross-review on the @openmaic publish prep Cross-review (Claude /code-review + codex) on this PR surfaced: - renderer's advertised CJS entry was broken: it keeps @openmaic/dsl external and imports a runtime enum from it, but dsl is ESM-only (no `require` condition), so `require('@openmaic/renderer')` would throw ERR_PACKAGE_PATH_NOT_EXPORTED. Make renderer ESM-only: drop the `.cjs` rollup output, `main` now points at the ESM build, and the `require` conditions are removed from `exports`. (importer is unaffected — it bundles dsl, so its CJS build still works.) - prepublishOnly re-ran the test suite during `pnpm -r publish`, so a flaky test after dsl had already published gave a non-atomic partial release. Reduce prepublishOnly to a build-only guard (never ship stale/empty dist) and move the real test/typecheck gate into the workflow, before any publish. - document that an @openmaic/* tag publishes the whole family via `pnpm -r` (pnpm skips already-published versions); the tag is a release marker, not a per-package gate. Verified: dsl + renderer + importer build; renderer emits ESM only (0 .cjs), all exports entries resolve; `npm pack` ships dist + README + LICENSE with no src leak; frozen-lockfile passes. Refs #778. * style: reflow @openmaic/dsl type imports past print-width after rename The @maic -> @openmaic rename lengthened two single-line type imports past prettier's 100-col width; prettier --check flagged them. Pure formatting. Refs #778. * docs(importer): mark @openmaic/importer browser-only (cr-loop accepted limitation) codex cross-review flagged that the published @openmaic/importer throws `XMLHttpRequest is not a constructor` when loaded in a pure Node process — its rollup build is browser-targeted (`nodeResolve({browser:true})` + a browser pdf.js build). The app only consumes it client-side ('use client'), so this is by design. Document it as an accepted limitation: prominent browser-only note in the README and a `browser` field in the manifest.

fix(classroom): adapt complete page to short viewports instead of clipping (#1461) The complete page centers its content in an overflow-auto flex section. When the content is taller than the stage viewport (common on laptops), the centered overflow clips beyond the scroll origin at the top — the trophy is unreachable and the page opens mid-content. Restore an adaptive compact layout: a ResizeObserver with hysteresis (760/820px) toggles the page between full and compact forms so the content always fits, and a dedicated inner scroll layer keeps the decorative background pinned to the viewport when scrolling is still needed. Add an e2e spec covering both layouts and trophy reachability. Co-authored-by: wyuc <wang-yc24@mails.tsinghua.edu.cn> | 17 小时前 | |
refactor(generation): consume the package everywhere and delete lib/generation (#1090) Part D of #1057 — the switch.

feat(media): write generated media through the asset pool under server-backed persistence (#1392) * feat(media): store generated media in the asset pool when persistence is server-backed With server-backed persistence the document is durable and shared, but generated media stayed in the producing browser: the document kept its gen_img_* / gen_vid_* placeholder and narration kept a browser-derived audio id. Every new browser that opened such a course re-ran generation for every slide, and it never converged, because the address of the generated bytes was never written back into the document. Under server-backed persistence only, the classic generation chain now stores bytes in the asset pool first and writes the id the pool allocated into the document. - The client bootstrap configures the asset seam alongside the document and runtime seams: an HttpAssetStore over the persistence endpoint carrying the same credentials the document store carries, marked server-backed. The seam preflight now covers all three, so a failure still cannot half-configure persistence. - Image, video and TTS generation commit in one fixed order: provider, pool, document, local cache, task. A reference reaches the document only after put returned an id, so a document can never name bytes that were not stored. A failure before the write-back leaves the placeholder with the provider called exactly once; the retry happens on the next owner load. - The write-back is a per-slot rewrite through mutateDocument, which re-reads the current document under the per-stage lock, so it cannot clobber a newer scene. The open course is refreshed with the same rewrite without being marked dirty. - "Has this already been generated?" is answered by the document (the slide exists and no longer holds the placeholder) instead of by this browser's task table. - The classroom's resume effect fails closed on ownership: only a resolved owner starts generation, so a viewer opening a shared course spends nothing. - The local media and audio tables become a per-tab cache. A failed cache write costs a re-download, never the media. Browser-only mode is unchanged: every new call site sits behind the server-backed gate, the local tables stay authoritative there, and placeholders stay in the document. Rendering and export needed no changes. HttpAssetStore.resolve mints an object URL exactly as the browser store does, and the export byte resolver was already pool-first. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XypYpLBtk8DB5nT5jyqZ5D * fix(classroom): make the generation owner gate a three-outcome rule and apply it everywhere The gate refused everything but a resolved owner, which read a sidecar that answered "no ownership fact exists for this course" as a reason to block. That is the answer a deployment without the sidecar's server-side prerequisites gives for every course, and the answer a course with no ownership record gives: in both, there is nobody the operator's budget needs protecting from, and refusing strands the course's own author behind a question that can never be answered. Ownership is now four states over the sidecar's three outcomes. A definite answer splits into owner and not-owner. An absent record is its own answer, ownerless, and generation proceeds — the behaviour such a deployment had before the gate existed. Only the absence of an answer, a transport failure or a load that has not asked yet, stays unresolved and fails closed: "we could not ask" must never be read as "nobody owns this". One mapper turns a sidecar result into that state, and one predicate decides on it. The workbench classroom pane runs the same resume effect and had no ownership input at all, so a viewer opening a shared course there could still spend the budget. It now asks the sidecar once per course, in parallel with its load and feeding only the generation gate, so its read-only and edit behaviour is unchanged. The shared progressive-load policy carries the gate for it, with both new inputs required rather than defaulted so a future caller cannot omit them into an open budget. Its stale comment claiming ownership could not be expressed here is corrected. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XypYpLBtk8DB5nT5jyqZ5D * fix(media): make the write-back survive autosave, arrive before the scene does, and never leak Independent reviews of the write-back found three ways a durable document could still end up naming a placeholder, and two ways the gate that protects the operator's budget could be walked around. An autosave round captures the store synchronously and writes that capture, so a round already in flight when a rewrite landed wrote the placeholder straight back over the allocated id, and nothing marked the store dirty again to correct it. The rewrite now marks the units it changed, which leaves a corrective flush queued behind the stale one; re-saving a scene that already holds the id is idempotent, losing the id is not. Media is generated from outlines in parallel with scene content and usually finishes first, so the slide that will carry the placeholder does not exist yet and the write-back has nothing to rewrite. That was the ordinary path, not a tail case, and its result was discarded: the task was marked done, the scene was added afterwards with its placeholder intact, and a second pass in the same run could call the provider again. The allocation is now held under the placeholder — which also answers the skip test, so nothing pays twice — and applied when that scene is committed, before its first save. One complete pass now leaves no placeholder behind. A failed commit used to abandon what it had already allocated. A poster upload that failed threw away a stored video and sent the retry to submit the most expensive job in the system again; a rejected write-back left registry rows that name bytes nothing references, which the byte collector cannot reclaim because it only collects blobs no row names. A poster failure now costs the poster, and a write-back that reached nothing reclaims what it allocated. A partial write is left alone, because the document already names it. The ownership gate is fail-closed again. Treating the sidecar's 404 as permission was wrong: the client cannot tell "this course has no owner" from "this deployment told me nothing", so a visitor who opened a shared course could bill the operator. The root cause was the sidecar itself, which gated on the agent runtime although every persisted course has an owner regardless — the persistence route resolves one for every request. It now gates on server persistence, so the configuration that made 404 the universal answer has real ownership facts to report, and the gate can refuse everything but a named owner. Retry affordances answered to no gate at all. A viewer of a shared course with one failed image was shown a Retry button that called the provider. Both retry entry points and every surface that draws them now read one shared permission, so what is offered and what is allowed are the same value. Also: narration regeneration no longer pretends it can replace bytes behind a live id — the exclusivity proof that would allow it is refused by construction once references leave the browser, so it forks to a fresh id and says so; the "already generated" test lets a finished deck answer from the document alone, since scene order stops identifying an outline once slides are inserted or deleted; stored assets record a specific media type rather than a generic transfer type; the pane no longer asks the sidecar in browser-only mode; and the funnel's docstring now states what the per-stage lock actually guarantees, which is same-browser serialization and not a cross-browser compare-and-swap. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XypYpLBtk8DB5nT5jyqZ5D * fix(media): park allocations in the deciding turn, never reclaim on an ambiguous write A delta review of the write-back found the first-pass fix still had a window, and the reclamation it added could delete media the document already names. The allocation was parked after an awaited local cache write. A scene committed in that window reconciled against a registry that did not hold it yet, so the document kept the placeholder — and the entry recorded a moment later then answered the skip test as "already handled", so nothing could correct it. Parking now happens inside the write-back, in the same synchronous turn as the decision that nothing could take the reference; no await separates the live check from the park. Allocations parked by an earlier pass are handed to their slides at the start of the next one, before anything decides what still needs generating, so a held allocation whose scene has since arrived becomes a rewrite rather than an answer. Reclaiming on a rejected write was unsound: a rejection does not prove the server did not apply the write, so deleting the asset could break the scene that now names it. The funnel decides instead, and says so: it reclaims only when no store write was ever issued and nothing took the reference. Anything else is placed if its slide exists and parked if it does not, so the next pass reuses the bytes instead of paying for them again. When a write fails after part of it landed, the live store is brought up to the document before the error is rethrown — otherwise the next ordinary flush would overwrite the half that did land, with the ids deliberately not reclaimed. Parked allocations are now cleared with the course. Classic placeholders are reused across runs, so one surviving an interrupted run would be handed to a different slide of the next deck: the previous picture, on a slide whose provider was never asked. Both classroom surfaces clear the arriving course, the deletion cascade clears the deleted one, and clearing the database clears them all. Two more ways generation could start without asking the gate are closed. An overlapping pass — an outline retry re-enters generation with every outline while the first is still working — re-requested elements whose provider call was already in flight; a task that is not done is an answered request, not an unanswered one. And narration regeneration in the timeline editor called the TTS provider and allocated a pool asset with no ownership check at all; it now reads the same permission, which withholds both the per-line and whole-timeline controls and refuses the call. Finally, a pane opened during the stage-link availability gap recorded the sidecar's 404 for a course that was moments from existing and never asked again, leaving the real owner locked out of generation until it remounted. Ownership is re-fetched once the document becomes available; the gate stays closed until an answer arrives, so asking again can only open it for someone entitled to it. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XypYpLBtk8DB5nT5jyqZ5D * fix(media): make the asset routes reachable, and stale snapshots harmless A full-branch audit found that the deployment this project documents could not store a single generated asset, and that several routes into durable storage could still write a placeholder over a reference that had already landed. The persistence route sent asset requests through the development authenticator, which refuses outright in a production build that has not explicitly opted into it — and the documented server-persistence recipe produces exactly that build. Every store and every read answered 401, so images and video failed on every slide while re-billing the provider on each retry, and a narration failure stopped the deck at its first slide. Assets live in one shared partition by design, so there was never anything per-caller for that authenticator to decide: the route now resolves the asset principal itself, alongside the owner it already resolves for documents. Runtime sessions are genuinely per-learner and keep the development authenticator until real session verification replaces it. And narration that cannot be stored no longer fails its scene: the line stays unvoiced and retryable, which is what an image that cannot be stored does to its slide. Placeholders could also come back from behind. A queued autosave's snapshot, an editor-history entry replayed by an undo, the departing save a course switch flushes — each captures content at its own moment, and any of those moments can predate a write-back. Point fixes at each producer would leave the next producer to rediscover the bug, so the check lives at the write boundary every producer passes through, and the allocation record it consults now outlives the parked queue: a placeholder whose rewrite landed long ago is exactly the case it catches. Two ways generation could be lost or repeated are closed. A pass now claims the elements it will reach and releases them however it ends, so an overlapping pass stands down while an aborted one strands nothing — previously its tasks stayed `pending` and every later pass skipped them with no retry control to recover them. And the media abort controller is aborted before being replaced, so a superseded pass stops calling providers instead of running on for a course the user has left. The remaining two are narrower. The workbench pane asks for ownership only after a document load succeeds, and after every later one, mirroring the page route: the load is what creates the ownership row the first time a course is opened, so asking beforehand asked about a course that did not exist yet and locked its author out for the mount. And the ownership gate on the timeline editor now withholds narration regeneration alone; listening back to existing narration and seeing whether a line has any spend nothing and stay available. Known limitation, unchanged and now stated plainly in the comments that used to point at it as a solution: nothing reclaims an unreferenced pool asset. The registry sweep is written but not wired up, and the byte collector only reclaims blobs no registry row names, so every narration regeneration and every abandoned allocation leaves storage behind. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XypYpLBtk8DB5nT5jyqZ5D * fix(media): gate asset mutations, and make claims and allocation records survive a handoff Opening the asset routes opened all of them. Reads and allocations are meant to be as open as document reads and creates already are, but no authorization hook was supplied, so the handler's default admitted PUT and DELETE too — and those scope by principal key alone, which is one shared constant. Any caller who learned an id, and a document read hands out every id its slides name, could overwrite or destroy another author's media. Mutations now require the deployment's credential, which in a production build without the development-auth opt-in means they are refused outright; reads and allocations stay open. The route comment says what the posture is and what it is not: the deployment-level fence is the access code, and no per-principal quota is configured. The client's own reclaim is best effort to match — losing an argument about deleting an asset must not cost a task its retry, and the bytes are left for server-side reclamation. The pass claim could not survive the handoff it was written for. A retry aborts the live media pass and starts its replacement in the same synchronous block, long before the aborted pass's cleanup runs, so the replacement saw every element still claimed, collected nothing, and returned — leaving each unreached element at pending with nobody coming back for it and no retry control to recover it, which is the exact failure the claim was introduced to prevent. A claim now carries its pass's signal and is retired the moment that signal aborts, and a pass releases only claims it still owns, so a late unwind cannot take its replacement's work. Claims are also acquired at the single point every request passes through, so a single-task retry participates too — previously a retry awaiting its provider was invisible to a pass starting alongside it and both called it. The allocation record could outlive the bytes it named. It was written before the write-back attempted anything and survived the reclaim that followed a failure, so when the slide finally arrived the write boundary stamped a deleted id into the document — and the placeholder it replaced was gone, which reads as already generated and stops anything from retrying. The record is now written only where the allocation is retained, and forgotten wherever a reclaim removes the bytes, including the narration rollback path. The tests follow. The route test drives the real storage handler against an in-memory registry instead of a stub, so it can see what the resolved principal is then allowed to do; the handoff test performs a real abort mid-pass rather than starting from an already-aborted signal; and the guards that could only assert file layout now assert the property they care about, or have been replaced by behaviour. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XypYpLBtk8DB5nT5jyqZ5D * fix(media): make media passes serial per course instead of tracking element ownership Three rounds of per-element claims each produced a new way to lose an element. Whole-pass reservations swallowed a Retry for an element the same pass had already failed, leaving it pending with the affordance gone. Retiring a claim by its signal freed an element whose commit was still uploading, so the replacement pass paid for it twice. A claim held for a failed element stranded its retry. The bookkeeping is the defect: every refinement of "who owns this element right now" answered the question at a moment when the answer was already stale. Passes for one course are now serial. A replacement aborts its predecessor, as before, and then waits for it to settle before collecting. That removes the question entirely: a commit already under way finishes — its bytes stored and its reference written, so the new pass sees a resolved slide and skips it — and an element the aborted pass never reached is still a placeholder and gets collected like any other. The claim set, the reservations, the signal retirement and the identity-checked release are all gone. The task table is consulted for one thing only: an element that is generating right now is a single-element retry running alongside the pass, and taking it too would pay twice. Pending is deliberately not a skip reason — it means a pass once intended to reach an element, which an abandoned pass leaves behind with nobody acting on it, and reading that as answered is what stranded elements before. A retry runs concurrently with a pass, because a pass never revisits an element it has processed, and it re-reads the task after its own await and refuses before touching it: marking first and refusing afterwards destroyed the failed state that draws the affordance. Browser-only mode is back to exactly what it was. The abort is now conditional, the waiting does not apply, and the original status-based skip is restored verbatim. Two baseline lines remain changed in each of the two files, and both are behind a server-backed fork whose else-branch is the original. Two smaller things. The allocation record becomes visible when a write goes on the wire rather than when the round trip ends, and the write boundary reconciles under the document lock rather than before it — a save queued during a write-back was otherwise captured with the placeholder and, for a course the user had left, had no corrective flush to follow. And the comments that said a refused reclaim leaves its bytes for server-side reclamation were wrong: nothing collects them, because the registry entry still names its blob and the sweep that would remove it is not wired up. They now say the bytes leak. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XypYpLBtk8DB5nT5jyqZ5D * fix(media): make a deferred pass re-earn its right to run, and bound the commit it waits on Serializing passes moved their body out of the block that launched them, and three things followed from that. A pass now wakes when its predecessor settles, which can be after the user has left the course. It enqueued before it looked at its signal, into a task table keyed by element id alone — and placeholder ids are not unique across courses, which is why the classroom clears that table on arrival. So a departing course's pass seeded the arriving course's table with tasks carrying the wrong stage id, and a Retry routes by that id: the reference went into the wrong document. A pass now re-validates after the wait, before touching anything shared. The same lateness broke the skip test. `documentSkipIndex` answers only while the live store is on the pass's stage, and returning nothing put the collection loop on the browser-only rule — a silent demotion from "the document is the authority" to "this browser's task table is", on exactly the path where that table has just been cleared. Every element the predecessor had committed was collected again, paid for again, and its second write-back found no placeholder to rewrite, so its bytes were parked where nothing will ever reference them. In server-backed mode an unreadable document now means the pass stands down. And waiting was unbounded. A commit is uncancellable: the asset client takes no signal, and a document write cannot be half-undone. One stalled upload therefore froze the course's media generation for the session — the replacement never collected, the element sat on a skeleton that draws no Retry, and only a reload recovered. The pass's signal is now threaded into the media proxy fetch, and the commit is bounded by a deadline. The deadline is on the wait, not the work: the commit carries on, and if it lands late the document simply ends up correct, while the element becomes retryable and the queue moves on. The tests that were meant to pin the previous round were not sensitive to it. Two asserted end states where the mechanism only changes ordering, and one of them rigged the document read so the assertion held whether or not the pass had waited; a third covered half of what it claimed. They now observe the ordering directly — nothing is issued while another pass for the course is working; in browser-only mode a second pass reaches its provider immediately — and the reconciliation under the document lock has a test that fails when it moves back outside it. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XypYpLBtk8DB5nT5jyqZ5D * revert(media): drop the commit deadline and the abortable download The deadline bought less than it cost. Abandoning a commit after two minutes makes the element retryable while the real commit is still running, so a Retry starts a second commit for the same placeholder against the first: two provider calls, two allocations, and whichever lands second stamps its result over the other's task by element id. The allocation record is keyed by placeholder, so the loser's cleanup erases the winner's record, and the write boundary then puts the raw placeholder back into the document. That is the overlap serial passes were built to remove, reopened through the one door serialization never covered. So a stalled commit holds the course's media queue until it settles or the page is reloaded, and that is written down rather than papered over. The wait is unbounded on purpose: every ceiling on it turns out to be a way of running two commits for one element. Threading the pass signal into the download was also a mistake, in the other direction. The provider call that produced the URL has already been billed, so cancelling the download throws away work that is paid for — and the shared proxy cache records a cancelled request as a transient failure against that URL, which after three of them blocks it for every consumer in the session. Browser-only mode never asked for this: it had no way to observe an abort there, which is exactly why the bytes were kept. The signal is gone from the download again, and `fetchAsBlob` is byte-for-byte what it was before this branch. The regression guard for the stranded-element rule is restored alongside the timing test that was meant to supersede it. It catches a different rule — a task left pending being read as answered — and nothing else does: making the pass skip pending leaves every other suite green. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XypYpLBtk8DB5nT5jyqZ5D * fix(media): stop asking the pool for refs it never issued, bound it, and adopt cached bytes Four things a deployment found once this was running for real. A reference this application mints itself — a generation placeholder, a derived narration key — was never in the pool, because the pool allocates every id it holds. Asking anyway used to be an IndexedDB miss; once the pool is server-backed it is a request that answers 404, one per element per load, forever on a course that still holds placeholders. Every lease and probe now checks first. The check is a negative test on shapes this application owns, not an id validator: the pool's id domain stays unconstrained, and anything that is not one of ours is still asked about. The asset store can bound how much one principal holds, and enforces it inside the write transaction, but nothing ever passed the number. It does now, with a default rather than an opt-in: allocation is reachable by any caller a deployment admits, and with one shared principal an unbounded store is unbounded database growth with no operator-visible brake. Refusing asset mutations to unauthenticated callers was not enough, because every authenticated caller resolves to that same shared principal — so authentication decided nothing, and any signed-in visitor could delete any id they learned. Since this branch began storing media the registry is the only copy a course has. Replacing and deleting are now refused to everyone, and the browser no longer tries: an entry nothing references waits for server-side reclamation instead. What a browser must still do is forget its own record of an allocation that reached nothing, or a later save would stamp an id the document has no reason to trust. And a course generated before any of this holds placeholders in its document with its bytes only in the author's browser. Those bytes are paid for, so the author's next load converts them — stored to the pool and written back through the ordinary commit path, with no provider call — instead of buying them again. A row that records only a hosted URL is treated as absent: that URL is the provider's address, not something a document may hold. One renderer expectation moved with this. An untracked placeholder used to paint as pending on first render because asking the pool left a lease in flight; it settled to disabled a moment later either way, and now says so from the start. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XypYpLBtk8DB5nT5jyqZ5D * fix(media): surface a full store as a refusal and convert legacy narration A quota refusal reached the browser as HTTP 500 with a generic message, which reads as a transient failure: the element kept a Retry that would pay a provider again and be refused again. The store raises the contract's own error and the handler maps it to 507, but the store answering a request is not always built by the same bundle as the handler -- the persistence provider is reached from the route bundle and from instrumentation, which is why its state lives on a Symbol.for global -- and `instanceof` is false across that boundary while the declared code is still right. Classify on the code as well as the class, and make the code a permanent, persisted refusal in the browser: recorded locally so it survives a reload, shown as "storage is full", and refused by the retry entry point so a stale button cannot buy a second generation. Every other storage failure stays retryable. Convert what a pre-server-backed course still holds. Generated media is adopted under either key this application has used for it -- the placeholder, and the allocated id of a course converted once and later rolled back -- instead of only the first. Narration is converted by a load-time pass over the open course's speech actions, since nothing re-enters generation for an action that already has an id: bytes to the pool, id written back through a funnel that mirrors the media one, owner-only and server-backed-only. A line whose bytes are in no browser is left alone rather than re-synthesized. Also: the pool guard is now a positive `ast_` test rather than an enumeration of the shapes we mint (imports never reach the pool, so this is safe in both modes); the slide ref collection is an exported pure function so its four lease sites are covered behaviourally; ASSET_QUOTA_BYTES treats every spelling of zero as opting out and refuses a malformed value at startup instead of falling back; the abort signal is re-checked after the cache read, before an uncancellable commit; and the unused `removeAsset` and pool `replace` surfaces are gone.

Same contract, stricter recognition, no API change: a patch. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XypYpLBtk8DB5nT5jyqZ5D * fix(media): make a full store recoverable and adoption course-safe Narration adoption read the local audio row by its derived key alone. That key carries no stage id and the table is keyed by id alone, so two courses can mint the same one -- a PPTX import numbers its scenes and actions deterministically, which gives every imported deck's first slide `tts_s1_speech-scene-p1`. Locally a collision only means one course plays another's clip in one browser; adopting it wrote that clip into the shared document permanently, for every device and every visitor. A row that names a course is now adopted only into that course, and a row from before that column existed only when the text it recorded is the text of the action being converted. A full asset store was made permanent last round, which was wrong three times over: it overwrote the refused bytes with an empty blob -- on the conversion path that row is a course's only copy of its own media -- it kept sending the rest of the deck to a provider against a ceiling it already knew was reached, and it left no way back once an operator raised that ceiling. A full store is neither the content's fault nor the configuration's, so it is now its own case: the bytes are kept, the pass stops at the first refusal, and the element shows the reason together with a Retry that re-attempts the upload from those bytes. Nothing retries automatically, so no one is re-billed. The narration write-back now reaches the write boundary every producer of a durable write passes through, not only the dirty mark: adoption never deletes the derived row, so a snapshot that reverts the rewrite is adopted again on the next load and allocates a fresh asset every time. Adoption is also mounted by both classroom surfaces rather than one, takes the course's abort signal, and re-validates that this browser still has the course open before each write. ASSET_QUOTA_BYTES is validated from instrumentation, where the README and the docstring already claimed it was: its only other consumer is lazy and memoised, so a malformed ceiling let the process boot and then failed every persistence request, documents and runtime included. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XypYpLBtk8DB5nT5jyqZ5D * fix(media): remember a full store per course, and never lose retained bytes A stopped pass left the elements it never reached as placeholders with no persisted record -- deliberately, since nothing was attempted for them. But that left the next load with no reason not to try: it called a provider for the next placeholder and was refused at exactly the same point, once per reload, indefinitely. A full store is not a property of any slide. It belongs to the deployment and changes for reasons the document knows nothing about, so it is now remembered once per course in the browser's device KV. A pass that finds the marker stands down before spending anything and leaves every placeholder its "storage is full" state and its Retry; the first upload that succeeds clears it and the next pass runs normally. Narration adoption latched per course so it runs once per load, and the latch outlived the abort that leaving a course performs. On a surface that stays mounted across switches -- the workbench pane is one component for every course it shows -- owner course A, visitor course B, then back to A skipped exactly the clips the abort had cut off, and nothing else converts them. The latch is released with the abort now, and a course adopts one run at a time so a re-entry cannot hand a clip a second allocation while the previous run's uncancellable tail is still settling. A quota-blocked element retried into a network error or a 500 lost the bytes that were kept for it: the retry deleted the row before attempting the upload and wrote no replacement for an error carrying no structured code, so the next retry went back to a provider for media this browser had a moment earlier. The row now survives until an upload succeeds, the failure handler keeps whatever bytes the attempt was given, and the retry asks the question a pass asks -- does this browser already hold bytes for this element -- rather than reading an error code that a second failure has already overwritten. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XypYpLBtk8DB5nT5jyqZ5D * fix(media): adopt real legacy narration, queue re-entries, report attempt outcomes Narration adoption admitted a stage-less row only when the text it recorded matched the action being converted. Both of those columns were added to the local audio table by the very change that moved narration onto allocated ids, so a row still carrying a derived key has neither: the rule refused every real pre-allocation course and passed only on fixtures built from post-allocation rows. What the row cannot say, the key can. A derived key names two clips only when two courses share a scene order and an action id, and an action id repeats only when something other than the generator minted it -- an import numbers them by slide position. So a key built from a generated action id is adopted on that basis, a key an import could have reproduced still needs matching text, and a row that names another course is refused however unique its key looks. Handing a re-entering caller the adoption run already in flight undid the latch release it was paired with: that run is bound to the signal the departure just aborted, so it stops at its next clip while the caller -- which has the course open and a live signal -- is told the work is done, and an effect replayed as mount, cleanup, mount adopts nothing at all. A later caller now waits for the uncancellable tail and scans again, which costs a lookup on a course that has nothing left and finishes the clips the abort cut off on one that does. One attempt at an element now reports both facts its callers need instead of a bare boolean: whether the store refused it for room, and whether bytes actually reached the store. Leaving a course clears the task table, so a retry that landed afterwards read "no failed task" as success and deleted the row holding the only copy of the media. Nothing is inferred from that table any more. Reading the localStorage property can throw where storage is denied by policy, typeof included, so the availability check moved inside the guard: this metadata is best-effort, and a rejection here strands a generation pass that has already enqueued its tasks. A retry is never blocked by the per-course "store is full" marker, but a retry that is refused again re-sets it, and adoption now reads and writes the same marker rather than issuing one refused upload per clip on every load. The two canvas element renderers and both thumbnail renderers show the reason beside the Retry, so a full store does not look like an ordinary failure. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(media): probe a full store instead of standing down, and pair notices with a Retry Narration adoption was given both halves of the per-course "the store is full" marker last round: it stood down when the marker was set, and it set the marker when its own upload was refused for room. Those halves are only safe together if something can lift the marker, and for adoption nothing could. It has no affordance of its own, it stood down before reaching its own clear, the media pass returns before its marker gate when there is nothing to generate -- so a narration-only deck, or one whose slides are already satisfied, painted no storage-full element and offered no Retry -- and narration generated rather than adopted allocates directly rather than through the media commit. The course's cached narration was then lost for good, where before it converted on the first load after the ceiling was raised. The gate is a probe now. A marked course attempts exactly one clip per load: refused, it stops and the marker stands, which costs what standing down cost; stored, it lifts the marker and finishes the course. Adoption spends no provider money, so the whole cost of probing a store that is still full is one refused upload. Generated narration lifts the marker too. The three surfaces that gained a failure notice last round drew it for any failure with a reason, including the one refusal that is reachable without server-backed persistence, so a browser-only deck painted something it had not painted before. The notice is drawn beside a Retry and nowhere else, which is what it was added for and what leaves browser-only output unchanged. Both are now asserted through the render harness the surface matrix already had. A caller arriving while a rescan is queued shares it rather than appending another. One rescan converts whatever the run in flight left and every later one would find an allocated id on every action, so a chain bought nothing and turned a single stalled upload into a course that never adopts again. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(media): treat a refusal for room as a fact about one clip, not the deck The asset store checks each write against the headroom it has left, so a store that refuses a long opening clip can still hold every short clip behind it. Narration adoption assumed the opposite: it broke the deck at the first refusal and then re-attempted that same first clip on every later load, because the document names it first. A deck whose longest clip exceeds current headroom therefore never converted the clips that would have fit, with no affordance to recover it -- the state the probe was introduced to remove, reached through a narrower door. An unmarked load now attempts every clip, skipping the ones that do not fit, and remembers the condition only if the load ends with clips it still could not store. A marked load spends its single upload on the smallest clip left rather than the first one named: that is the clip that answers the question the marker asks, because if the smallest does not fit nothing does. The media pass keeps stopping at its first refusal, and for a reason adoption does not share -- every element it attempts costs a provider call. A rescan several callers share took the newest caller's signal, and the newest caller is not necessarily the one still there: a surface that opened a course and closed it again would stop work a surface still showing that course was waiting for, and that surface is latched, so it would never ask again. The shared run now takes a signal that is aborted only once every caller has left. The comment claiming the shared rescan contains a stalled upload was wrong -- the rescan is chained off the run in flight, so a stalled upload leaves every caller pending exactly as a chain would. It claims the bounded queue it actually provides, and the stall is recorded as a limitation. The failed-state containers took their stacking classes unconditionally, so markup differed in browser-only mode even though nothing moved on screen. Those classes are applied only when there is a notice to stack, and the tests assert the exact class attribute rather than a substring. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(media): stop narration adoption writing the media pass's store-full marker The marker means "do not call a provider for this course". A path is entitled to write it only if its own refusal cost a provider call, and narration adoption's refusals cost nothing: it uploads bytes this browser already holds. The store also checks each write against the headroom it has left, so a clip that does not fit says nothing about whether a slide's image would. Adoption was writing it anyway, and one over-long narration clip was therefore enough to stand a course's entire image pass down on every later load -- on a store that had just accepted adoption's other clips. The author could still recover each element by hand, every load, for ever. Three rounds of narrowing this seam produced a finding each time, so it is removed rather than narrowed again. Gone: the marker read, the single-clip probe, the smallest-clip selection, and the up-front read of every row into an array -- which also retires a sampled-then-stale flag and the retention of a whole deck's blobs for the length of a run, and returns the loop to streaming one row at a time. Adoption's rule is now that every load attempts every clip it holds, once; any failure skips that clip and the load continues. The noise the coupling was meant to avoid does not arise, because after the first load the clips still outstanding are exactly the ones that did not fit -- normally none, or one. A successful write still clears the marker, and that is a different kind of statement: a write that went through is a fact this run established, where a refusal is an inference about what some other write would cost. For a course whose media needs nothing, adoption and generated narration are also the only paths that can establish it. The failure module still documented the deck-wide premise this contradicts. It now says what is true: the check is per write, and the media pass stops the deck as a judgement about cost rather than about certainty. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(media): bound a full store's cost from the store's own arithmetic Removing the store-full marker from narration adoption removed its bound too, and the code then asserted the bound was unnecessary. It is, on a store with room for most of a deck. On the store the whole mechanism exists for -- the ceiling reached, nothing fitting -- the outstanding set after every load is the entire deck, so a thirty-clip course posted thirty full blobs on every load, indefinitely. Each of those is not a cheap refusal: the bytes are uploaded, the server hashes the whole payload, and only then takes a per-principal lock and sums every entry that principal owns before saying no. The bound needs no flag, no key and nothing carried between loads. The store asks whether `used + addedBytes` exceeds the ceiling, and `used` only grows while a run is uploading, so a clip refused for want of room implies every clip at least that large is refused for the rest of that run. The run keeps the smallest size it has been refused and skips anything no smaller without uploading it; a smaller clip is still attempted, because it may fit. A deck the store refuses entirely now costs one upload per successive size minimum instead of one per clip, and a deck it has room for costs nothing extra, because nothing is refused. Only a refusal for room lowers the bar: a dropped connection says nothing about how much room there is. The deck-wide certainty premise the failure module retracted last round still stood verbatim at the site that implements the stand-down. Both copies now say the same thing: the check is per write, and the pass stops the deck as a judgement about cost rather than about certainty. The comment on adoption's marker clear now names its price. Narration of a few hundred bytes fits in headroom an image does not, so a proven write can let the next pass buy one more image that is refused again -- bounded at one, and the price of the alternative being a course whose media never generates again. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * docs(media): state the adoption bound exactly, and stop three comments describing the old rule The comment introducing the in-load bound gave its cost as "at most a handful, and the first load pays the most". Neither clause is a property of the rule. A clip is skipped only when something no larger was already refused, so a fully-refused deck costs one upload per successive size minimum in document order: one when the clips grow, about ln N for an arbitrary order, and one per clip when they only shrink -- a long opener followed by terser lines is exactly that shape. And no load is cheaper than the first, because the bound resets per run and a refused clip stays outstanding. The comment now says that, and points at what would make it exactly one for any ordering: the store returning its remaining headroom in the refusal's existing details channel, which the server leaves empty today. Two other comments still described the previous rule -- "attempts every clip it holds, every load" -- one of them twenty lines above the paragraph that introduces the bound, in the same block. Both now say what the code does. The bound's soundness is worth stating where a maintainer will look for it: quota is charged at full length with no discount for a duplicate, the sum it is checked against joins entries to blobs so the collector cannot lower it, the check takes a per-principal lock before summing, and replace and delete are refused to every browser. Nothing a run can do makes room appear inside it. One test installed a row implementation and replaced it wholesale a few lines later, so the first was dead and the survivor dropped the text the first clip's import-shaped key needs for the ownership rule -- it passed on the coincidence that the fixture's default text is the action's. Merged into one. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(media): keep a Retry from re-buying parked media, and state the store seam once Five findings from an inline review. The standalone classroom route asked the ownership sidecar once per load and recorded only stage ownership when that ask failed. Every non-answer fails closed, so one transient 5xx left the genuine author with no resume, no Retry affordance and no legacy narration converted for the rest of the load, with nothing to change it short of a reload. The failure now records the fail-closed answer explicitly -- an answer an earlier load established must not outlive the failure that replaced it -- and an unresolved answer is asked for again, a few times over a few seconds. A real answer, however unwelcome, is final. A Retry could pay a provider for media the pool already held. When the bytes are stored and only the write-back fails in a way that keeps the allocation, it is parked and no local row exists, because that row is written only after a successful write-back. Retry now reads the parked queue exactly as the pass does and re-attempts the write-back: it re-keys the task done when the document takes it, leaves the entry parked when the slide still does not exist, and stays failed and retryable when the document refuses again. Object URLs a parked allocation owns are revoked when the entry is dropped. The commit path leaves them alone while the entry is parked, because it is then the only thing holding bytes this tab can render, so a course switch or a stage deletion was pinning the whole blob for the life of the tab. An entry a slide has already taken is left alone: the task table is displaying those URLs. The fallback lookup for cached bytes is a stage-scoped scan, and the keyed lookup misses for every row the commit path writes, so a pass was materializing and sorting the course's whole media table once per element. One scan per pass now, built on the first miss. It is sound and not merely cheaper: an element asks only for its own placeholder, and every row a pass writes carries the placeholder of the element that wrote it. "The store accepted a write, so it is not out of room" was enforced at three call sites under slightly different conditions, which made it a convention the next pool write path could silently break. It is stated once, in putAsset, for the course whose bytes it just stored.

build(node): enforce direct dependency engine floor (#1337) Why: - The root Node 20.9 contract predates direct runtime dependencies whose declared minimums now reach Node 22.19. - README, contributor, localized docs, and the OpenMAIC extension skill repeated the stale supported-version claim. What: - Raise the root Node minimum to 22.19 and align every operator, contributor, locale, and skill prerequisite. - Add a check that compares the root minimum with installed direct production dependency engine minimums. - Run the new contract check in CI after the frozen dependency install. Risk: - This changes the declared minimum only; no upper bound is added and Node 24 compatibility remains a separate concern. - The localized docs build was validated with the independent #1306 boundary fix from PR #1307, which is not included here. Tests: - RED on the base: engine check reported pi-agent-core, pi-ai, svg-pathdata, and undici floors - GREEN: root minimum 22.19 satisfies 35 engine-constrained direct dependencies - Node 20 lockfile-only install reports the root unsupported-engine warning - Node 22 frozen install and postinstall - Docs build with PR #1307 boundary: 34 pages and all locale postexport checks; docs types:check - Root Prettier, ESLint, TypeScript, i18n, package-version, and internal-dependency gates - Root pnpm test: 7137 passed, 81 skipped Live Docs: - GitHub issue #1304 tracks the Node contract; #1306 / PR #1307 tracks the separate docs-build prerequisite.

Removes resolveActiveStage and setActiveStage from the store interface, their PG implementations, the active_stage_changed lifecycle event, the session_active_stage owner event variant, and the contract tests pinning them. The active_stage_id column and the DDL check constraint stay untouched for schema compatibility. * chore(storage): bump @openmaic/storage to 0.7.0 for the contract removal * docs: document the agent runtime configuration surface (#1176) * fix(agent): repair orphaned and late tool results across interruption boundaries (#1180) * 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 the next claim sees a provider-safe transcript. * test(agent): pin the runner wiring for interruption-boundary tool repair * feat(agent): add neutral tool foundation libraries (#1184) * feat(agent): register a web_search tool on the session runner (#1185) * feat(storage): add a per-session URL trust gate (#1186) * feat(agent): add the skills system (#1189) * feat(agent): add the skills system (builtin directories and durable user skills) * 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. * fix(agent): share unstorable-character validation and align skill lookup * feat(agent): add session materials and a fetch_url tool behind the URL trust gate (#1190) * feat(agent): add session materials and a fetch_url tool behind the URL trust gate * fix(agent): harden session material fetching * feat(storage): add an ownership scope to stage documents (#1191) * feat(agent): add material read and search tools (#1192) * feat(agent): add stage read and patch tools (#1194) * feat(agent): add page generation and deck editing tools (#1198) * test(storage): keep the PG contract suite order-independent (#1200) * fix(agent): revoke deleted-session URL authority and reject private ISATAP endpoints (#1199) * fix(storage): revoke deleted session URL authority * fix(ssrf): reject private ISATAP endpoints in strict fetches * chore(storage): bump to 0.11.1 for the session-URL authority fix * feat(agent): add roster and voice registration tools (#1201) * feat(agent): add folder organisation tools (#1202) * feat(api): add stage and material HTTP routes (#1203) * feat(workbench): add the client data layer (#1204) * feat(workbench): add the client data layer * docs(workbench): write the ported comments in English * chore(edit): remove the in-editor agent panel (#1210) * chore(edit): remove the in-editor agent panel * style: apply prettier formatting * fix(agent): report the runtime as unusable without a database (#1207) * fix(agent): report the runtime as unusable without a database * style: apply prettier formatting * feat(agent): add image, video and pptx import tools (#1211) * feat(workbench): add the agent chat surface (#1205) * feat(workbench): add the agent chat surface * docs(workbench): write the ported comments in English * fix(workbench): label the folder and rename tools on the timeline * fix(workbench): label the roster and voice tools on the timeline The reconciliation test iterates every tool the runner registers and requires a display label of its own. The roster and voice-clone tools (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(agent): add the material extraction lifecycle (#1212) * feat(storage): add material extraction lifecycle * feat(agent): execute queued material extraction * style: apply prettier formatting * style: satisfy prefer-const in the extraction runner * test: give material fixtures the extraction lifecycle fields The media-tools slice and the extraction lifecycle slice were each green in isolation but never compiled together: the lifecycle made derivedFrom and extraction required on AgentSessionMaterial while the media-tool fixtures predate them. * chore: remove stray task notes * fix(workbench): label the extraction lifecycle tools on the timeline * feat(workbench): add the workspace shell (#1206) * feat(workbench): add the workspace shell * docs(workbench): write the ported comments in English * i18n(workbench): align workspace keys across locales * fix(workbench): adopt the landed data layer and label the extraction tools - replace the sibling-slice seam stubs with the real data-layer modules - drop ambient declarations now shadowed by landed files - port timeline labels for the extraction lifecycle tools from the reference - align the new i18n keys across all locales * ci: retrigger * 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. * fix: forward the freshness manifest through the owner-bound store * feat(workbench): add the Pro entry points and preserve the mode-transition semantics (#1208) * 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. * docs: keep ported comments in English and deployment-neutral * docs: announce 1.0.0 and refresh the feature overview (#1216) * docs: announce 1.0.0 and refresh the feature overview * docs: finalize 1.0.0 README after feature merge * 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. * fix(workbench): restore editor chrome, mode transition, streaming, materials, mentions, folders (#1229) * fix(workbench): wire workspace folder routes * fix(editor): restore reference workbench chrome * fix(workbench): persist composer materials and course refs * fix(workbench): preserve live reasoning frames * fix(persistence): back off failed streaming saves * chore(workbench): retire stale slice seams * test(editor): cover element pin layer * chore(storage): bump to 0.21.0 for the user-message ref/material fields * chore(editor): translate ported code comments to English * fix(agent): fence durable tool writes and consume cancel requests atomically (#1230) * fix(agent): enforce provider force-off in agent tools and scrub vendor identity from tool results (#1231) * fix(materials): serialize per-owner quota reservations and make crashed uploads reclaimable (#1232) * fix(editor): resolve dock-bar i18n keys, remove dock height drag, wire element referencing (#1233) * fix(workbench): send the opening session message exactly once with refs intact (#1234) * feat(editor): port timeline TTS preview single-flight and voice-all state latching (#1235) * fix(media): restore the reference classic media chain (#1236) * fix(import): adapt imported PPTX canvas size so decks render without overflow (#1237) * fix(editor): complete element referencing — renderer DOM contract and GenUI picking aligned with the reference (#1238) * test(providers): reconcile the provider-config vendor-token debt count after the main merge The integration line's AK/SK fallback for the managed document provider adds occurrences that main's allowlist snapshot predates. Same mixed-composition debt category the group already documents; no new vendor behavior. * test(providers): reconcile vendor-token debt counts with the integration line The main-merge brought main's neutrality-guard snapshot next to integration features it predates (media-extractor fallback chain, local voice-profile deletion semantics, the enabled-TTS helper). Same debt categories the guard already documents; counts updated to the guard's own tally and two grouped entries added. No new vendor behavior. * fix(agent): carry reasoning through the completions dialect so the thinking strip renders (#1239) * feat(skills): add Feynman and spiral curriculum methods (#1240) * feat(agent): port missing reference tools and skills (parity audit) (#1241) * feat(media): retire asset-registry wiring; media and materials follow the reference byte model (#1242) * fix(classroom): center adapted canvases in the stage and send back navigation home during generation (#1243) * feat(settings): skill management with real list, download, delete, and upload (#1244) * feat(settings): skill management section with real list, detail, and zip download * feat(skills): owner skill delete and upload across storage, API, and settings * fixup! feat(settings): skill management section with real list, detail, and zip download chore: neutralize a reference note in the settings header comment * fix(media): persist origin-independent classroom-media references from the agent runtime (#1245) * 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.

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. Co-authored-by: Claude Fable 5 <noreply@anthropic.com> * 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. --------- Co-authored-by: Claude Fable 5 <noreply@anthropic.com> | 15 天前 | |
feat(video-export): service-backed MP4 render + in-app one-click export (#866) (#937) * feat(video-export): service-backed MP4 render + in-app one-click export (#866) Adds the last mile of classroom video export: turning the self-contained Hyperframes project ZIP (#865) into an MP4 via an isolated render service, one-click in-app. - render-service/: standalone Node 22 + Chromium + FFmpeg container wrapping @hyperframes/producer's library API. Async job model (POST /render -> 202 jobId, GET poll, GET download, DELETE cancel). Swappable JobStore / ArtifactStore seams (in-memory + local-disk now; Redis/S3 + presigned-302 download later) so it scales horizontally without changing the HTTP contract. Concurrency + per-user guards are config knobs. - App integration: thin Next proxy routes under app/api/export-video/* (forward only, no rendering) + capability probe. use-render-video.ts uploads the ZIP, polls via runPolledTask, downloads the MP4; shared buildExportZip prefix with the existing ZIP path. Export menu gains resolution/fps/quality selectors and a progress bar; degrades to ZIP download when RENDER_SERVICE_URL is unset. - docker-compose: render-service under an opt-in "video-export" profile. - Entry is main.ts (not server.ts): the producer auto-starts its own server on :9847 when the process entry path ends with /src/server.ts. Verified end-to-end in the container: rendered a real 640s (10.7 min) classroom ZIP to a valid H.264 720p + AAC MP4 (duration matches source) in ~9.6 min (~0.9x realtime, 4-worker frame capture). Degrade path, queued-cancel + cleanup, and per-user 429 guard all exercised. pnpm check / lint / tsc / i18n pass. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * feat(video-export): global render progress store, percent+ETA UI, ring on export button (#866) Addresses two UX issues found while driving the in-app MP4 export: 1. Progress display was raw and unfriendly (showed producer's English stage strings like "Capturing frame 5130/19220") and had no time estimate. Now the menu shows only "<percent>% · about <remaining> left". ETA is computed from a recent-speed estimate (percent-per-ms over the last sample), EMA-smoothed — which tracks the render's non-uniform pace (prep -> frame capture with a 4->1 worker drop -> encode) far better than a whole-run average, and never shows a stale/rising ETA. 2. Switching scenes mid-render unmounted the export menu and lost the progress (and reset the local "already rendering" ref, allowing a duplicate submit). The whole render lifecycle now lives in a global store (lib/store/video-render.ts), so progress survives menu close / scene switch and duplicate submits are guarded by status. A persistent CircularProgress ring on the export button shows live progress whether or not the menu is open. Also fixes the progress scale: the producer reports progress as 0..100, but our HTTP contract (and success path) is 0..1 — the service now normalizes it, so the client no longer showed "2000%". - lib/store/video-render.ts: new global store owning submit->poll->download, recent-speed ETA, duplicate-submit guard. - lib/video-export-app/use-render-video.ts: thin facade over the store. - components/ui/circular-progress.tsx: lightweight SVG progress ring. - components/stage/{header-controls,video-export-menu}.tsx: ring on the export button; menu shows percent + ETA, subscribes to the store. - render-service/src/render-manager.ts: normalize producer progress 0..100 -> 0..1. - i18n: percent/ETA strings across all 8 locales (drops the stage-based string). - render-service/package-lock.json: complete integrity hashes (reproducible npm ci). Verified: ETA logic checked against the real segmented render curve (worker drop raises ETA, encode speedup drives it to ~0); progress scale fix confirmed live against the container (0.2 -> 20%). tsc / lint / prettier / i18n pass. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(video-export): persist render options in the store, not the menu component Selecting 720p/24fps/draft, switching scenes, and reopening the export menu showed the defaults again (1080p/30/standard). The selections lived in the VideoExportMenu component's local state, which reset when the menu unmounted on a scene switch — the running render still used the chosen options, but the UI misrepresented them. Move resolution/fps/quality into the global video-render store (with a setOptions action). The menu now reads/writes the store, so selections survive menu close / scene switch, and while a render runs the selectors reflect the options that render is actually using. startRender() reads options from the store instead of taking them as an argument. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(video-export): deployment correctness + resource/isolation controls (PR #937 review) Addresses the blocking findings from wyuc's review. Output fidelity was fine; these harden deployment and production resource/isolation boundaries. #1 Compose advertised MP4 but couldn't render in prod: - Capability now probes the service's /health (checkRenderServiceHealth), so a configured-but-absent service reports disabled and the UI degrades to ZIP instead of 502-ing. - RENDER_SERVICE_URL is operator-supplied trusted config, so the proxy no longer runs it through the SSRF guard — the one-command `docker compose --profile video-export up` now works without globally weakening SSRF via ALLOW_LOCAL_NETWORKS. resolveRenderServiceUrl() is now synchronous. - Client degrades to ZIP on any failed submit (not only 501). #2 Unbounded upload/queue (ZIP-bomb / DoS): - unzip.ts bounds the archive via fflate's filter BEFORE decompression: entry count, per-entry and total expanded size, and compression ratio. - Proxy rejects oversized uploads (413) by Content-Length before forwarding. - RenderManager enforces a global queue-depth cap (RENDER_MAX_QUEUE). - All limits are env-tunable knobs in config.ts. #3 Per-user guard was ineffective + admission ran after extraction: - Identity is derived server-side (client IP) and forwarded as x-openmaic-client; the service ignores any client-supplied userId, and the proxy strips it. - Admission is split into reserve()/submit()/release(): the slot is reserved BEFORE extraction, so a rejected caller never triggers a decompression. Additional risks: - Per-job wall-clock watchdog (RENDER_JOB_DEADLINE_MS) aborts + fails a hung render so it can't hold a slot/scratch forever. - Download proxy bounds only the time-to-headers, not the body stream, so large MP4s over slow links no longer truncate. - Client cancels the server job (DELETE) when a started render fails/times out. - Compose puts render-service on an internal:true network (no host/internet route), sandboxing the Chromium that runs the uploaded HTML; the export ZIP is self-contained so no outbound is needed. README documents the standalone caveat. Not closing #866: the smoke/golden-render CI acceptance criterion remains a follow-up (see PR description). Verified in-container: legal render 202; ZIP-bomb (entry-count + compression- ratio) rejected 400 before any decompression; per-identity guard 429 with a spoofed multipart userId ignored; reserve-before-extract leaves no scratch dir on rejection; watchdog aborts an overrunning job and frees the slot. tsc / lint / prettier / i18n pass; render-service tsc passes. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(video-export): real audio durations + burned-in subtitles (PR #937 review) Two export-fidelity issues found in wyuc's deeper E2E: A. Narration was scheduled from estimated durations, cutting audio off mid- sentence and advancing the timeline early. The scheduler trusted AudioFileRecord.duration (recorded only since #861), so the many existing classrooms without it fell back to text-length estimates — measured 4.35s average / 10.23s max underestimate across 47 clips. timeline-deps now probes the real duration from each narration blob via an off-document <audio> (symmetric to the existing video probe), preferring it over the stored duration, then the estimate only when no audio asset exists. Everything downstream (narration starts, scene/total duration, subtitle cues) re-derives from the corrected value in the pure compiler — no compiler change needed. B. The final MP4 had no subtitles (only H.264+AAC), and the ZIP's SRT/VTT used the same estimated boundaries. The emitter now renders a burned-in subtitle overlay: one caption box + a hidden div per cue, revealed/hidden by the paused GSAP timeline at each cue's start/end (corrected timings from A), so Chromium's frame capture bakes them in. The producer has no subtitle track of its own, so burn-in is the v1 approach. Verified: emitter unit tests + snapshot updated (subtitle overlay + toggle statements, escaped text, hidden-by-default); 82 video-export tests pass incl. the determinism red-line proxy. Rendered a synthetic subtitle project through the container and confirmed by pixel analysis that captions appear only within their cue window (2429 near-white px in the caption band at t=1.5s vs 0 at t=0.05s). tsc / lint / prettier / i18n pass. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(video-export): subtitle layout + upload/admission hardening (PR #937 review) Address the three P1 blockers plus actionable P2s from the 6a585c29 review. P1: - emit-hyperframes: stack every subtitle cue in one grid cell and toggle display:none/inline-block, so inactive cues leave the flow instead of pushing the active cue up into the slide title. Adds a multi-cue regression test the single-cue snapshot couldn't catch. - render route + service: cap the upload by actual bytes (capBodyStream), not the spoofable Content-Length; the app now streams the multipart body through instead of buffering it via formData(). maxUploadBytes is now read. - render-service: move makeProjectDir() inside the release()-guarded block so an ENOENT/ENOSPC no longer permanently leaks the admission slot; mkdir the scratch root at startup for the standalone path. P2: - config: allow RENDER_MAX_JOBS_PER_USER=0 to disable the per-identity guard. - timeline-deps: per-probe timeout + bounded concurrency so a stuck audio blob can't wedge export in "compiling" forever. - render route: only trust x-forwarded-for/x-real-ip under TRUST_PROXY_HEADERS=true; otherwise all callers share one "direct" bucket. - render-service: add vitest tests (unzip limits/traversal, reservation arithmetic, body cap, config zero-disable) and a dedicated CI job. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(video-export): sync render-service lockfile so `npm ci` passes in CI The vitest devDependency's transitive esbuild@0.28.1 (and its platform optionals) were missing from package-lock.json, so the new CI job's `npm ci` failed with EUSAGE. Regenerated the lockfile from a clean install. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(video-export): dedupe esbuild so render-service `npm ci` installs on linux @hyperframes/core pins esbuild@0.25.12 exactly, hoisting it to the top and forcing vite@8 (via vitest) to keep a nested esbuild@0.28.1 copy. npm fails to flag that nested copy's platform-specific optionals as optional, so `npm ci` tried to install @esbuild/aix-ppc64 on linux and died with EBADPLATFORM. Add an `esbuild: 0.28.1` override so a single copy is shared (satisfies tsx ~0.28 and vite ^0.27||^0.28); esbuild is build-time only, so pinning the producer's bundled build tool is runtime-inert. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(video-export): resource/isolation hardening (PR #937 round-2 review) Address the round-2 P1/P2/P3 findings (P1#1 lockfile EBADPLATFORM was already fixed by the earlier esbuild-dedupe commit; CI Render Service job is green). P1: - Admission before buffering (#2): the render service now reserve()s the slot from the header identity BEFORE parsing/buffering the multipart, so concurrent near-cap uploads are bounded by the queue depth, not just each body by the cap. - Chromium egress lockdown (#3): the producer exposes no browser-arg hook and the render shares the internal network with the app, so a container entrypoint installs an iptables egress lockdown (drop all outbound except loopback + established replies) then drops privileges. Needs CAP_NET_ADMIN (added in compose); graceful warn-and-continue if unavailable. The self-contained ZIP needs no outbound. - Default one-render bottleneck (#4): with no trusted proxy every caller is "direct", so RENDER_MAX_JOBS_PER_USER=1 throttled the whole deployment. Default compose now sets it to 0 and relies on concurrency + global queue caps. - Non-blocking bounded extraction (#5): unzipSync -> fflate async unzip (worker, off the event loop), keeping the pre-decompression filter; default expanded ceiling 1GB -> 512MB; a semaphore caps concurrent extractions; compose adds a container mem_limit. P2: - Raise the app submit timeout/maxDuration (300MB upload can't finish in 60s). - video-render store: only degrade to ZIP when the service is genuinely unavailable (501/unreachable); surface real 429/413/5xx instead of an unsolicited download. - useExportVideo dedupe guard moved to module scope so it survives the menu unmounting (no second concurrent ZIP pipeline). - .env.example: RENDER_SERVICE_URL bypasses SSRF; drop the ALLOW_LOCAL_NETWORKS note. P3: - Deadline overruns are marked failed (not cancelled). - submit() decrements the identity slot if jobs.create throws (no leak). - CI sets PUPPETEER_SKIP_DOWNLOAD; unzip tests use tiny fixtures + low env limits. Tests: render-service now 22 tests (unzip limits/traversal, admission incl. create-leak, body cap, semaphore, config); app video-export suite unchanged. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(video-export): buffer under the extraction permit + fail-closed egress (PR #937 round-3) Address the two remaining round-3 P1 boundary blockers. P1#1 — buffering was outside the gate: `bounded.formData()` materialized the whole uploaded file into memory BEFORE `extractionGate.run()`, so up to RENDER_MAX_QUEUE (20) admitted bodies could each buffer ~300MB (≈6GB vs the 4g mem_limit) before the 2-permit gate. Move the entire RAM-heavy section — formData buffering, file read, and unzip — INSIDE the permit; the queue reservation still runs first (a rejected caller consumes nothing). Requests beyond the permit wait with their body unconsumed (socket backpressure), so at most maxConcurrentExtractions bodies are buffered at once. Refactored main.ts into a testable `createApp(deps)` factory and added an integration test proving peak concurrency in the buffering+extraction section never exceeds the permits. P1#2 — egress lockdown failed open: the entrypoint warned and started normally if iptables setup failed, so /health stayed green while Chromium could reach the app. With RENDER_EGRESS_LOCKDOWN=true (default) it now FAILS CLOSED — exits non-zero if not root, iptables is missing, or the rules don't apply. Operators accepting an unisolated setup opt out with RENDER_EGRESS_LOCKDOWN=false. Added scripts/egress-smoke.sh to assert the boundary (lockdown active, loopback works, new outbound blocked). Verified: image builds; container boots as `render` with lockdown active and serves /health; fail-closed exits 1 without CAP_NET_ADMIN; egress smoke passes (outbound blocked); 23/23 render-service tests + tsc; app tsc + root prettier clean.

fix(ssrf): keep cloud metadata endpoints blocked under ALLOW_LOCAL_NETWORKS (#1419) * fix(ssrf): keep cloud metadata endpoints blocked under ALLOW_LOCAL_NETWORKS ALLOW_LOCAL_NETWORKS=true exists so self-hosted deployments can point providers at loopback, RFC1918 and split-horizon targets. It also returned early from validateUrlForSSRF before any classification, so a client-supplied base URL of 169.254.169.254 (or metadata.google.internal, 100.100.100.200, fd00:ec2::254) was accepted on such deployments. Cloud instance-metadata endpoints are now rejected regardless of the flag: literal hosts and IPv4-mapped forms are classified directly, and non-IP hostnames are resolved so an answer that lands on a metadata address is rejected too. DNS failure under the flag still fails open, as before, because split-horizon DNS is an explicit use case of the flag. Without the flag the DNS path now also rejects answers on metadata addresses that are not RFC1918 (100.100.100.200). The route tests that used the metadata address as their example of a target the flag allows now use a private-network address instead. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01GRaNc5E88r41GUWt2Y3uiQ * fix(ssrf): widen the metadata set and bound the flagged DNS lookup Review follow-up. Add the AWS ECS task credential and EKS Pod Identity endpoints (169.254.170.2, 169.254.170.23, fd00:ec2::23), the Azure WireServer address (168.63.129.16) and the legacy OCI IMDS address (192.0.0.192) to the blocked set; the last two are neither RFC1918 nor link-local, so they were reachable even without the flag. Recognise the metadata addresses when carried inside 6to4, Teredo, ISATAP and NAT64 literals. Bound the DNS lookup done under the flag to three seconds and fail open on expiry, matching the existing fail-open on error. Say in .env.example that the set is a fixed list and that DNS failure is allowed through. Use the same private-network fixture for the reject and allow cases of the four route guard tests so a partial NODE_ENV re-gate of the guard goes red again. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01GRaNc5E88r41GUWt2Y3uiQ * fix(ssrf): share the tunnel decoder between the private and metadata checks Review follow-up. assertSafeIp now classifies metadata addresses through isCloudMetadataAddress, so an ISATAP identifier under a globally routable prefix that carries 168.63.129.16, 192.0.0.192 or 100.100.100.200 is rejected on the strict-fetch path too. isPrivateIP uses the same tunnelEmbeddedIPv4 helper instead of its own copies of the 6to4, Teredo and ISATAP decoders, which also gives it NAT64. Tests cover the globally-routable ISATAP forms, the NAT64 private case, and the false-positive direction (tunnel literals carrying public or RFC1918 addresses stay allowed under the flag).

The metadata hostname and address check now runs before the ALLOW_LOCAL_NETWORKS branch, so metadata.google.internal is rejected by name in both flag states (previously only under the flag), and metadata literals get the metadata message rather than the one that suggests setting the flag. Pin the tunnel decoder boundaries in tests (2001:db8 is not Teredo, 64:ff9b:1 is not NAT64, 2003 is not 6to4).

feat(token-plan): one-click token-plan setup + deployment usage dashboard (#784) * feat(usage): add usage normalization, pricing, model-fetch, balance, storage Foundational layer for token-plan usage tracking (cc-switch-modeled): - lib/usage/normalize.ts: AI SDK v6 usage → four-class token shape - lib/usage/pricing.ts + defaults: per-class USD pricing table - lib/server/model-fetch.ts: /models candidate-URL multi-fallback (ported) - lib/usage/balance-providers.ts: built-in balance queries + detection - lib/server/usage-storage.ts: fire-and-forget jsonl logging to data/usage All pure/storage logic covered by vitest (32 tests). * feat(usage): capture token usage at the callLLM/streamLLM chokepoint - callLLM records result.usage before returning - streamLLM wraps onFinish to record totalUsage on stream completion, preserving any caller-supplied onFinish - provider/model derived from the model instance (no route changes) - fs-backed storage imported dynamically; fire-and-forget, never throws - include_usage is already sent by @ai-sdk/openai, so streaming is covered * feat(usage): add probe-models, balance, and usage API routes - POST /api/provider/probe-models: discover chat models via /models with candidate fallback; SSRF-guarded; filters non-chat ids; 401/404 typed - POST /api/provider/balance: built-in balance detection + billing fallback - GET /api/usage: aggregate jsonl by model/day/source with costIncomplete flag Verified e2e against the live MAIC gateway: 16 chat models (6 filtered), balance detected, and a real callLLM writes a costed usage row. * feat(settings): add token-plan preset picker to provider dialog - lib/config/token-plan-presets.ts: data-driven vendor presets (Huawei/MiniMax/ Xiaomi token plans, OpenRouter/SiliconFlow gateways, DeepSeek/GLM/Qwen/Hunyuan/ Doubao direct) with baseURL, protocol, optional modelsUrl, category - add-provider-dialog: '选择厂商/自定义' tabs; picking a preset auto-fills baseURL+protocol+modelsUrl, custom tab unchanged - ProviderSettings.modelsUrl carries the optional /models override - i18n keys added across all 8 locales Verified in-browser: preset picker renders grouped by category. * feat(settings): add Fetch Models button and balance bar to provider panel - 拉取模型: probes /models, merges discovered ids into the model list (dedupe, keeps manual additions), with success/no-endpoint/auth messages - 查询余额: queries /api/provider/balance, renders a balance bar or a 'check console' hint when unsupported - index.tsx: handleModelsFetched merges probe results into provider config - i18n keys across all 8 locales; removed a now-unused eslint-disable Verified in-browser against MAIC gateway: 16 models fetched, balance shown. * feat(settings): add usage dashboard to System Settings - usage-dashboard.tsx: echarts dual-axis daily trend (tokens + cost), totals cards, by-model table, refresh; reads GET /api/usage - mounted at the top of GeneralSettings (系统设置) - honest disclaimer + costIncomplete marker when a model lacks pricing - i18n keys across all 8 locales Verified in-browser: shows 1 request / 31 tokens / $0.0003 from a prior call. * feat(token-plan): multi-modal one-click setup in System Settings - token-plan-presets.ts: presets now declare per-modality targets (llm/image/video/tts/webSearch); MiniMax is the full-set template, others LLM-only — extend by adding entries (at-our-best adaptation) - apply-token-plan.ts: fills one key into every declared modality via injected store setters, isolating per-modality failures (TDD, 4 tests) - token-plan-settings.tsx: new sidebar page — pick plan, enter key, one-click apply lights up adapted modalities (+LLM model probe), shows 'not adapted yet' for the rest, balance bar reused - reverted add-provider dialog to plain custom form (preset picker moved here) - i18n across all 8 locales Verified in-browser: Token Plan page renders, MiniMax shows all 5 modalities, apply/balance UI wired. 859 tests pass, build clean. * feat(token-plan): add custom token plan entry to Token Plan page - Custom card at the bottom of the provider list: pick it to manually enter name + protocol + baseURL (LLM-only), then key + one-click apply via the same applyTokenPlan flow (mirrors cc-switch's custom provider) - effectivePreset unifies preset vs custom for apply/balance/probe - i18n keys (customGroup/customName/customHint) across all 8 locales Verified in-browser: custom card expands the manual form; preset flow intact. * feat(token-plan): reflect persisted config on the Token Plan page Other settings panels read the store directly, so they survive section switches; the Token Plan page only wrote the store, so it looked blank on return. Now it also reads providersConfig: - selecting a preset prefills its saved API key - configured presets show a '已配置/Configured' badge State persistence was never broken (apply writes zustand→localStorage); this fixes the missing read-back so the page reflects it. * fix(settings): isLLMProviderConfigured crashed on providers without models Root cause of 'token plan config disappears': applyTokenPlan writes a new LLM provider with no models yet (probe fills them later). isLLMProviderConfigured did config.models.length unguarded → threw inside setProviderConfig's resolver → the whole set() aborted → key/baseUrl/type never persisted. - guard models in isLLMProviderConfigured (shared validator; affects any provider written without a models array) - seed models:[] in applyTokenPlan's LLM write for a valid initial shape - regression tests: validator no longer throws; apply+probe write keeps apiKey Verified in-browser: DeepSeek persists key and shows 已配置 after section switch. * feat(token-plan): add remove/teardown for a configured token plan Apply had no inverse. Add removeTokenPlan: clears the API key and disables (enabled:false) every modality the plan declared; a custom LLM provider is deleted entirely (removeProvider), built-ins keep the cleared shape. - removeTokenPlan in apply-token-plan.ts (mirrors applyTokenPlan, isolated per-modality, injected setters; 3 tests) - trash button on configured preset cards in the Token Plan page; resets page state if the removed plan was selected - i18n 'remove' across all 8 locales Verified in-browser: removing DeepSeek empties its key and drops the 已配置 badge. * feat(usage): track multimodal usage, drop cost/pricing Reframe usage stats as pure usage (no cost), per user decision: - usage-storage: drop all cost fields; add kind (llm/image/video/tts/asr) + quantity + unit; LLM keeps token counts, others store quantity - delete lib/usage/pricing.ts + pricing-defaults.json + its test - instrument image/video/tts at the server-only API routes (not in the provider dispatch — those files are in the client graph and importing fs-backed usage-storage broke the client bundle) - /api/usage: aggregate by model/day/modality, no cost - dashboard: per-modality usage (tokens/images/seconds/chars), token-only daily trend, no '$'; i18n cost keys replaced with modality/unit keys - backward compatible: legacy rows (no kind, stray cost fields) read as llm 912 tests pass, build clean. * feat(usage): per-modality dashboard layout + softer dark-mode chart - group usage into per-modality sections (LLM/image/video/tts/asr), each table's usage column uses one consistent unit (token/image/sec/char) — no more mixed units in a single column - summary chips per modality with their own unit - trend chart now plots daily REQUESTS (unit-agnostic, works for any modality) instead of LLM-only tokens - theme-aware chart: faint thin line + soft gradient area, muted axis/grid colors via useTheme — fixes the harsh solid stroke in dark mode Verified in-browser (dark): TTS shows '字符', LLM shows 'Token', separate sections; chart no longer has a hard line. * refactor(usage): dedupe model/fetch/usage helpers, parallel balance probe Review cleanups on the token-plan/usage branch: - extract modelInfoFromId() (shared vision heuristic + ModelInfo shape) - extract fetchWithTimeout() shared by model-fetch and balance-providers - extract recordGenerationUsage() to dedupe the image/tts/video routes - queryBalance: fetch billing subscription + usage in parallel - parseOneApiBilling: report quota without remaining when usage endpoint is unavailable, instead of implying zero spend (full balance) - split the two jammed imports in settings/index.tsx * feat(token-plan): drop custom token-plan support Custom token plans (manual baseURL/protocol entry) added complexity for little gain — a one-off provider is better configured directly on the Providers page. Token Plan is now preset-only: - remove custom mode, manual fields, and the custom card from the UI - collapse effectivePreset back to the selected preset - drop the now-dead removeProvider action + custom-id branch in removeTokenPlan - remove orphaned customGroup/customName/customHint i18n keys (8 locales) * feat(token-plan): add Volcengine/Tencent/Bailian plans, drop balance feature Add three vendor token-plan presets (all map to existing built-in LLM providers, so it's data-only — no new adapters): - 火山方舟 Volcengine Ark → doubao, OpenAI /api/v3 - 腾讯 TokenHub Token Plan → tencent-hunyuan, OpenAI /plan/v3 (the plan-specific base; /v1 is the pay-as-you-go gateway) - 阿里百炼 Token Plan → qwen, cross-model plan (Qwen + DeepSeek/Kimi/ GLM/MiniMax) on one key; model list is probed/entered Remove the balance/quota feature entirely — we now track usage, not cost, and every vendor's balance query needs its own cloud AK/SK + signature (Volcengine SigV4 / Tencent TC3 / Aliyun BSS), which the Bearer-key billing-endpoint probe never supported anyway: - delete lib/usage/balance-providers.ts, /api/provider/balance, its test - strip the Check Balance button + balance bar from the token-plan page and the provider config panel - remove the 4 balance i18n keys across all 8 locales - restore an eslint-disable the branch had dropped in provider-config-panel * feat(token-plan): use cloud-brand logos for vendor token plans The three vendor plans are cloud offerings, not single-model products, so icon them with the cloud brand rather than a model logo: - 火山方舟 → volcengine.svg (was doubao.svg) - 腾讯 TokenHub → tencentcloud.svg (was hunyuan.svg) - 阿里百炼 → alibabacloud.svg (was bailian.svg) Logos are the colored brand variants from lobehub/lobe-icons, matching the existing colored-logo style (plain <img>, no dark:invert needed). * feat(token-plan): keep only MiniMax and Volcengine presets Trim the token-plan list to the two we want to ship: MiniMax (full-set template) and 火山方舟 Volcengine Ark. Drop the Tencent/Bailian plans and the OpenRouter/SiliconFlow/DeepSeek/GLM/Qwen entries. - remove the now-unused tencentcloud.svg / alibabacloud.svg logos (volcengine.svg stays; the other logos are still used by the provider registry) - retarget the LLM-only apply test from the deleted deepseek preset to volcengine-ark * feat(token-plan): restore aggregator/third-party presets Previous commit over-trimmed: the intent was to drop only the Tencent and Bailian token plans, not the OpenRouter/SiliconFlow/DeepSeek/GLM/Qwen entries. Bring those back; keep only Tencent/Bailian removed. - token_plan: MiniMax, 火山方舟 Volcengine Ark - aggregator: OpenRouter, SiliconFlow - third_party: DeepSeek, GLM, Qwen Revert the apply test back to the deepseek fixture (restored). tencentcloud.svg / alibabacloud.svg stay deleted (their plans are gone). * fix(token-plan): point Volcengine plan at the Coding Plan endpoint The plan's ark--prefixed API keys authenticate only against /api/coding/v3, not the general /api/v3 endpoint — the latter rejects them with "The API key format is incorrect", so model probing returned nothing. Switch the base URL to https://ark.cn-beijing.volces.com/api/coding/v3. * fix(token-plan): Volcengine is an Agent Plan (Anthropic /api/plan) Per the Ark Agent Plan docs, the ark--prefixed keys authenticate ONLY against the dedicated Anthropic-compatible base https://ark.cn-beijing. volces.com/api/plan ("其他 Base URL 无法在 Agent Plan 中使用"). The general /api/v3 and the Coding Plan /api/coding endpoints both reject the key as "API key format is incorrect", which is why model probing kept returning 0. - baseUrl → https://ark.cn-beijing.volces.com/api/plan/v1 (the /v1 lets the Anthropic SDK land on /api/plan/v1/messages) - apiFormat → anthropic - rename to 火山方舟 Agent Plan Probe still targets /api/plan/v1/models (the path exists); if the Anthropic gateway doesn't return an OpenAI-shaped list, users fall back to typing a model id like ark-code-latest. * fix(token-plan): Volcengine Agent Plan = OpenAI /api/plan/v3 + ark-code-latest Settled after probing the real key and reading cc-switch's approach: - The ark- plan key works on the OpenAI-compatible /api/plan/v3 endpoint (chat/completions returns 200); switch apiFormat back to openai. - The plan exposes NO /models list (every /api/plan/*/models is 404), which is why probing kept returning 0. cc-switch handles this by hardcoding a single ark-code-latest (an auto-routing alias valid on any tier) and does NOT use AK/SK for model listing — so we do the same. - Seed defaultModels: ['ark-code-latest'] only; users add specific ids by hand. Supporting machinery (kept, general-purpose): - applyTokenPlan seeds models from defaultModels instead of wiping to [] - handleApply uses defaultModels and skips the doomed probe when present - drop stray .playwright-mcp/ debug artifacts and gitignore them * style: fix prettier formatting in usage files CI runs prettier on the whole repo (prettier . --check); these four files predate this branch's formatting pass and tripped the check. * feat(token-plan): verify Volcengine Agent Plan's published model set The Agent Plan publishes a fixed model set but exposes no /models endpoint, so carry the documented models as CANDIDATES and verify each on apply: - add verifyModels flag to TokenPlanModalityTarget - new /api/provider/probe-chat-models route: sends a minimal chat request per candidate (OpenAI /chat/completions or Anthropic /messages) in parallel, returns the subset that succeeds; SSRF-guarded, auth-failure short-circuits - handleApply gains a verify branch (before the fixed-defaultModels fast path), falling back to the seeded list if verification fails - Volcengine preset now carries the 12 published Agent Plan text models (doubao-seed-2.0-*/deepseek-v4-*/minimax-m*/glm-5.2/kimi-k2.*) as candidates This auto-prunes retired (docs flag deepseek-v3.2/glm-5.1 as 即将下线) and tier-gated models without code changes. Verified all 12 resolve against a real plan key. * feat(token-plan): wire Volcengine Agent Plan image + video modalities Make the Ark seedream/seedance adapters path-configurable and light up the image/video modalities on the Volcengine plan: - seedream/seedance adapters: resolveArkRoot() uses baseUrl verbatim when it already carries an /api/... path (token plan's /api/plan/v3), else appends the standard /api/v3 — no regression for the pay-as-you-go default host. - applyTokenPlan: image/video branches inject a modality's defaultModels as customModels and set them as the active provider+model, so generation works out of the box. New optional setImageProvider/ModelId + setVideoProvider/ ModelId actions (UI passes the store setters; tests omit them). - Volcengine preset declares image (doubao-seedream-5.0-lite, verified 200 on /api/plan/v3/images/generations) and video (doubao-seedance-2.0/1.5-pro — Medium+ tiers only; lower tiers reject at call time, no code change needed to upgrade). Applying the plan overwrites the shared seedream/seedance slot with the plan config (same overwrite model as LLM); switching back to pay-as-you-go is a manual edit or plan removal. Verified image end-to-end with a real plan key. * feat(token-plan): verify image/video models on apply, disable unsupported tiers The Volcengine plan lit up video optimistically, but lower tiers (Small) don't include video — so using it 404'd with UnsupportedModel. Probe media models on apply and only keep what the tier actually supports: - generalize /api/provider/probe-chat-models with a `kind` (chat|image|video): image hits /images/generations, video hits /contents/generations/tasks with empty content. The model-support check (404 UnsupportedModel) runs before any billable work, so probing never starts a real image/video job; for media, "supported" = any non-404 response. - handleApply: after lighting up image/video, probe each verifyModels modality; prune to the verified model set + re-select a working model, or disable the modality entirely if none pass (no false "available"). - Volcengine preset: image/video targets gain verifyModels: true. - add settings.tokenPlan.tierUnsupported across 8 locales. Verified with a real Small-tier key: image (seedream-5.0-lite) passes and is kept; video (seedance-2.0/1.5-pro) 404s and is disabled. * feat(web-search): add Doubao (豆包搜索) provider Doubao Search (Custom 版) over its REST endpoint POST open.feedcoopapi.com/search_api/web_search with Bearer auth — the same endpoint the askecho-search-infinity MCP server wraps, so the Volcengine Agent Plan key authenticates directly. Mirrors the MiniMax adapter: maps Result.WebResults to WebSearchSource (prefers Summary, the query-relevant excerpt, over Snippet for LLM use) and surfaces errors from ResponseMetadata.Error. - register 'doubao' in WebSearchProviderId + WEB_SEARCH_PROVIDERS - searchWithDoubao adapter, searchWeb dispatch, store default config - SSRF allowlist entry for the search host * feat(audio): support Agent Plan single-key auth for Doubao TTS generateDoubaoTTS now picks auth + endpoint from the key shape, since Volcengine exposes Seed-TTS as two products with separate credentials (verified: a plan key 401s on the normal endpoint, and the plan endpoint rejects appId-style auth): - single key (no colon) -> X-Api-Key, for the Agent Plan /plan endpoint - appId:accessKey -> X-Api-App-Id + X-Api-Access-Key (unchanged) A malformed pair (empty half) fails clearly instead of sending an empty header. Reuses the existing NDJSON/base64-mp3 parsing and voice list. * fix(media): map MiniMax video 720p to its real 768P tier normalizeVideoOptions defaults minimax-video to '720p' (the first supported resolution), but Hailuo 2.3 only accepts 768P/1080P and rejects 720P with '2013 ... does not support resolution 720P'. MiniMax's mid tier is 768P, not 720P (the adapter already falls back to 768P, as does the connectivity test), so map the shared enum's '720p' to 768P. Regression tests lock the mapping. * feat(token-plan): add web search + TTS to Volcengine Agent Plan, widen image tiers Extend the volcengine-ark preset now that the adapters exist: - webSearch -> doubao (own host open.feedcoopapi.com, not the ark endpoint) - tts -> doubao-tts on the /api/plan/tts endpoint (single-key auth) - image defaultModels widened to a best-first Seedream 5.0/4.5/4.0 list so a higher tier keeps the strongest model while verifyModels prunes the rest; video keeps the 2.0 + 1.5-pro candidates Comments record the verified host/auth quirks of each modality. * feat(token-plan): show result panel only after probing, with two clear states Addresses review feedback that a green check implied generation works when it only meant 'configured'. The panel now renders after probing finishes (gated on results && !applying) so it reflects the final set, and uses two states: green when the modality is configured/usable, muted when a live probe proved it unavailable (e.g. video on a tier without it). * feat(token-plan): scope presets to true multi-modal token plans Drop the single-modality LLM presets (OpenRouter, SiliconFlow, DeepSeek, GLM, Qwen) from Token Plan. A token plan's defining trait is one key spanning many modalities; those entries are ordinary LLM API providers already covered by the add-provider flow, and listing them here muddied the 'one key, every modality' promise. Only MiniMax and the Volcengine Ark Agent Plan remain. The UI already hides categories with no entries. apply-token-plan's LLM-only test now uses a local fixture instead of the removed deepseek preset. * feat(token-plan): progressive reveal of probe results on apply The result panel previously rendered all at once after probing finished, reading as dead air during the model probe. Now rows appear immediately on Apply: modalities with a live probe in flight show a spinner ('pending') and resolve to lit/failed independently as each probe returns, while non-probe modalities show lit right away. Probes run in parallel (Promise.all) instead of sequentially. A row only turns green once its own probe confirms, so this reveals structure + live progress without a premature green — complementing the earlier 'render only after probing' intent rather than reverting it. Per review feedback from @wyuc on #784. * fix(token-plan): enrich seeded models with built-in thinking capability Token Plan built ModelInfo objects from probed ids via modelInfoFromId(), filling only streaming/tools/vision — so a model that supports configurable thinking lost capabilities.thinking and InlineThinkingControl was hidden. modelInfoFromId now takes an optional providerId and overlays the catalog thinking capability for that (provider, model) pair; applyTokenPlan does the same for its synchronously-seeded list. Added the Ark Agent Plan's dotted aliases to the metadata table: - native Doubao Seed 2.0 family (doubao-seed-2.0-pro/code/lite/mini) - cross-vendor models the plan serves through its OpenAI-compatible endpoint (deepseek-v4-pro/flash, glm-5.2, kimi-k2.7-code/k2.6, minimax-m3/m2.7, ark-code-latest) All verified against a live plan key: each accepts the gateway's unified reasoning_effort field (low/medium/high) and actually reasons. They share the doubao effort adapter, which disables via 'minimal' (not 'none') — matching what the plan endpoint accepts (it rejects reasoning_effort:'none'). Addresses review point #1 from @wyuc on #784. * Improve token plan capability setup UI * fix token plan setup flow * chore: prettier format tts-providers.ts | 2 个月前 | |

chore(packages): publish the @openmaic/* SDK family to npm (#778) (#780) * chore(packages): publish the @openmaic/* SDK family to npm (#778) Prepares the @openmaic/{dsl,renderer,importer} family for its first npm publish, and moves the SDK packages onto the @openmaic scope. Why the scope move: the @maic org name is unavailable on npm (an unscoped `maic` package already holds the name), so @maic/* is not claimable. @openmaic matches the project name, the scope is free, and the repo already ships an @openmaic/docs package — so the SDK family now lines up with that convention. - rename @maic/{dsl,renderer,importer} -> @openmaic/* across packages, the workspace glob, the package dir, and all import sites; lockfile regenerated - renderer: add publishConfig (public, registry.npmjs.org) — was missing, so a scoped publish would default to the wrong registry / restricted access - importer: add a files allowlist (dist, README, LICENSE) and drop the fragile .npmignore blacklist that shipped src; add an exports map so ESM consumers resolve dist/index.js instead of falling back to the .cjs main - all three: add a prepublishOnly build (+ test/typecheck) guard so a publish can never ship a stale or empty dist - add a tag-triggered publish workflow with npm provenance, pinned by name to the three @openmaic packages so the vendored forks (mathml2omml, pptxgenjs) are never published Refs #778, #720 (Phase 1). * fix(packages): address cross-review on the @openmaic publish prep Cross-review (Claude /code-review + codex) on this PR surfaced: - renderer's advertised CJS entry was broken: it keeps @openmaic/dsl external and imports a runtime enum from it, but dsl is ESM-only (no `require` condition), so `require('@openmaic/renderer')` would throw ERR_PACKAGE_PATH_NOT_EXPORTED. Make renderer ESM-only: drop the `.cjs` rollup output, `main` now points at the ESM build, and the `require` conditions are removed from `exports`. (importer is unaffected — it bundles dsl, so its CJS build still works.) - prepublishOnly re-ran the test suite during `pnpm -r publish`, so a flaky test after dsl had already published gave a non-atomic partial release. Reduce prepublishOnly to a build-only guard (never ship stale/empty dist) and move the real test/typecheck gate into the workflow, before any publish. - document that an @openmaic/* tag publishes the whole family via `pnpm -r` (pnpm skips already-published versions); the tag is a release marker, not a per-package gate. Verified: dsl + renderer + importer build; renderer emits ESM only (0 .cjs), all exports entries resolve; `npm pack` ships dist + README + LICENSE with no src leak; frozen-lockfile passes. Refs #778. * style: reflow @openmaic/dsl type imports past print-width after rename The @maic -> @openmaic rename lengthened two single-line type imports past prettier's 100-col width; prettier --check flagged them. Pure formatting. Refs #778. * docs(importer): mark @openmaic/importer browser-only (cr-loop accepted limitation) codex cross-review flagged that the published @openmaic/importer throws `XMLHttpRequest is not a constructor` when loaded in a pure Node process — its rollup build is browser-targeted (`nodeResolve({browser:true})` + a browser pdf.js build). The app only consumes it client-side ('use client'), so this is by design. Document it as an accepted limitation: prominent browser-only note in the README and a `browser` field in the manifest.

build(node): enforce direct dependency engine floor (#1337) Why: - The root Node 20.9 contract predates direct runtime dependencies whose declared minimums now reach Node 22.19. - README, contributor, localized docs, and the OpenMAIC extension skill repeated the stale supported-version claim. What: - Raise the root Node minimum to 22.19 and align every operator, contributor, locale, and skill prerequisite. - Add a check that compares the root minimum with installed direct production dependency engine minimums. - Run the new contract check in CI after the frozen dependency install. Risk: - This changes the declared minimum only; no upper bound is added and Node 24 compatibility remains a separate concern. - The localized docs build was validated with the independent #1306 boundary fix from PR #1307, which is not included here. Tests: - RED on the base: engine check reported pi-agent-core, pi-ai, svg-pathdata, and undici floors - GREEN: root minimum 22.19 satisfies 35 engine-constrained direct dependencies - Node 20 lockfile-only install reports the root unsupported-engine warning - Node 22 frozen install and postinstall - Docs build with PR #1307 boundary: 34 pages and all locale postexport checks; docs types:check - Root Prettier, ESLint, TypeScript, i18n, package-version, and internal-dependency gates - Root pnpm test: 7137 passed, 81 skipped Live Docs: - GitHub issue #1304 tracks the Node contract; #1306 / PR #1307 tracks the separate docs-build prerequisite.

feat(media): write generated media through the asset pool under server-backed persistence (#1392) * feat(media): store generated media in the asset pool when persistence is server-backed With server-backed persistence the document is durable and shared, but generated media stayed in the producing browser: the document kept its gen_img_* / gen_vid_* placeholder and narration kept a browser-derived audio id. Every new browser that opened such a course re-ran generation for every slide, and it never converged, because the address of the generated bytes was never written back into the document. Under server-backed persistence only, the classic generation chain now stores bytes in the asset pool first and writes the id the pool allocated into the document. - The client bootstrap configures the asset seam alongside the document and runtime seams: an HttpAssetStore over the persistence endpoint carrying the same credentials the document store carries, marked server-backed. The seam preflight now covers all three, so a failure still cannot half-configure persistence. - Image, video and TTS generation commit in one fixed order: provider, pool, document, local cache, task. A reference reaches the document only after put returned an id, so a document can never name bytes that were not stored. A failure before the write-back leaves the placeholder with the provider called exactly once; the retry happens on the next owner load. - The write-back is a per-slot rewrite through mutateDocument, which re-reads the current document under the per-stage lock, so it cannot clobber a newer scene. The open course is refreshed with the same rewrite without being marked dirty. - "Has this already been generated?" is answered by the document (the slide exists and no longer holds the placeholder) instead of by this browser's task table. - The classroom's resume effect fails closed on ownership: only a resolved owner starts generation, so a viewer opening a shared course spends nothing. - The local media and audio tables become a per-tab cache. A failed cache write costs a re-download, never the media. Browser-only mode is unchanged: every new call site sits behind the server-backed gate, the local tables stay authoritative there, and placeholders stay in the document. Rendering and export needed no changes. HttpAssetStore.resolve mints an object URL exactly as the browser store does, and the export byte resolver was already pool-first.

That is the answer a deployment without the sidecar's server-side prerequisites gives for every course, and the answer a course with no ownership record gives: in both, there is nobody the operator's budget needs protecting from, and refusing strands the course's own author behind a question that can never be answered. Ownership is now four states over the sidecar's three outcomes. A definite answer splits into owner and not-owner. An absent record is its own answer, ownerless, and generation proceeds — the behaviour such a deployment had before the gate existed. Only the absence of an answer, a transport failure or a load that has not asked yet, stays unresolved and fails closed: "we could not ask" must never be read as "nobody owns this". One mapper turns a sidecar result into that state, and one predicate decides on it. The workbench classroom pane runs the same resume effect and had no ownership input at all, so a viewer opening a shared course there could still spend the budget. It now asks the sidecar once per course, in parallel with its load and feeding only the generation gate, so its read-only and edit behaviour is unchanged. The shared progressive-load policy carries the gate for it, with both new inputs required rather than defaulted so a future caller cannot omit them into an open budget. Its stale comment claiming ownership could not be expressed here is corrected. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XypYpLBtk8DB5nT5jyqZ5D * fix(media): make the write-back survive autosave, arrive before the scene does, and never leak Independent reviews of the write-back found three ways a durable document could still end up naming a placeholder, and two ways the gate that protects the operator's budget could be walked around. An autosave round captures the store synchronously and writes that capture, so a round already in flight when a rewrite landed wrote the placeholder straight back over the allocated id, and nothing marked the store dirty again to correct it. The rewrite now marks the units it changed, which leaves a corrective flush queued behind the stale one; re-saving a scene that already holds the id is idempotent, losing the id is not. Media is generated from outlines in parallel with scene content and usually finishes first, so the slide that will carry the placeholder does not exist yet and the write-back has nothing to rewrite. That was the ordinary path, not a tail case, and its result was discarded: the task was marked done, the scene was added afterwards with its placeholder intact, and a second pass in the same run could call the provider again. The allocation is now held under the placeholder — which also answers the skip test, so nothing pays twice — and applied when that scene is committed, before its first save. One complete pass now leaves no placeholder behind. A failed commit used to abandon what it had already allocated. A poster upload that failed threw away a stored video and sent the retry to submit the most expensive job in the system again; a rejected write-back left registry rows that name bytes nothing references, which the byte collector cannot reclaim because it only collects blobs no row names. A poster failure now costs the poster, and a write-back that reached nothing reclaims what it allocated. A partial write is left alone, because the document already names it. The ownership gate is fail-closed again. Treating the sidecar's 404 as permission was wrong: the client cannot tell "this course has no owner" from "this deployment told me nothing", so a visitor who opened a shared course could bill the operator. The root cause was the sidecar itself, which gated on the agent runtime although every persisted course has an owner regardless — the persistence route resolves one for every request. It now gates on server persistence, so the configuration that made 404 the universal answer has real ownership facts to report, and the gate can refuse everything but a named owner. Retry affordances answered to no gate at all. A viewer of a shared course with one failed image was shown a Retry button that called the provider. Both retry entry points and every surface that draws them now read one shared permission, so what is offered and what is allowed are the same value. Also: narration regeneration no longer pretends it can replace bytes behind a live id — the exclusivity proof that would allow it is refused by construction once references leave the browser, so it forks to a fresh id and says so; the "already generated" test lets a finished deck answer from the document alone, since scene order stops identifying an outline once slides are inserted or deleted; stored assets record a specific media type rather than a generic transfer type; the pane no longer asks the sidecar in browser-only mode; and the funnel's docstring now states what the per-stage lock actually guarantees, which is same-browser serialization and not a cross-browser compare-and-swap. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XypYpLBtk8DB5nT5jyqZ5D * fix(media): park allocations in the deciding turn, never reclaim on an ambiguous write A delta review of the write-back found the first-pass fix still had a window, and the reclamation it added could delete media the document already names. The allocation was parked after an awaited local cache write. A scene committed in that window reconciled against a registry that did not hold it yet, so the document kept the placeholder — and the entry recorded a moment later then answered the skip test as "already handled", so nothing could correct it. Parking now happens inside the write-back, in the same synchronous turn as the decision that nothing could take the reference; no await separates the live check from the park. Allocations parked by an earlier pass are handed to their slides at the start of the next one, before anything decides what still needs generating, so a held allocation whose scene has since arrived becomes a rewrite rather than an answer. Reclaiming on a rejected write was unsound: a rejection does not prove the server did not apply the write, so deleting the asset could break the scene that now names it. The funnel decides instead, and says so: it reclaims only when no store write was ever issued and nothing took the reference. Anything else is placed if its slide exists and parked if it does not, so the next pass reuses the bytes instead of paying for them again. When a write fails after part of it landed, the live store is brought up to the document before the error is rethrown — otherwise the next ordinary flush would overwrite the half that did land, with the ids deliberately not reclaimed. Parked allocations are now cleared with the course. Classic placeholders are reused across runs, so one surviving an interrupted run would be handed to a different slide of the next deck: the previous picture, on a slide whose provider was never asked. Both classroom surfaces clear the arriving course, the deletion cascade clears the deleted one, and clearing the database clears them all. Two more ways generation could start without asking the gate are closed. An overlapping pass — an outline retry re-enters generation with every outline while the first is still working — re-requested elements whose provider call was already in flight; a task that is not done is an answered request, not an unanswered one. And narration regeneration in the timeline editor called the TTS provider and allocated a pool asset with no ownership check at all; it now reads the same permission, which withholds both the per-line and whole-timeline controls and refuses the call. Finally, a pane opened during the stage-link availability gap recorded the sidecar's 404 for a course that was moments from existing and never asked again, leaving the real owner locked out of generation until it remounted. Ownership is re-fetched once the document becomes available; the gate stays closed until an answer arrives, so asking again can only open it for someone entitled to it.

The persistence route sent asset requests through the development authenticator, which refuses outright in a production build that has not explicitly opted into it — and the documented server-persistence recipe produces exactly that build. Every store and every read answered 401, so images and video failed on every slide while re-billing the provider on each retry, and a narration failure stopped the deck at its first slide. Assets live in one shared partition by design, so there was never anything per-caller for that authenticator to decide: the route now resolves the asset principal itself, alongside the owner it already resolves for documents. Runtime sessions are genuinely per-learner and keep the development authenticator until real session verification replaces it. And narration that cannot be stored no longer fails its scene: the line stays unvoiced and retryable, which is what an image that cannot be stored does to its slide. Placeholders could also come back from behind. A queued autosave's snapshot, an editor-history entry replayed by an undo, the departing save a course switch flushes — each captures content at its own moment, and any of those moments can predate a write-back. Point fixes at each producer would leave the next producer to rediscover the bug, so the check lives at the write boundary every producer passes through, and the allocation record it consults now outlives the parked queue: a placeholder whose rewrite landed long ago is exactly the case it catches. Two ways generation could be lost or repeated are closed. A pass now claims the elements it will reach and releases them however it ends, so an overlapping pass stands down while an aborted one strands nothing — previously its tasks stayed `pending` and every later pass skipped them with no retry control to recover them. And the media abort controller is aborted before being replaced, so a superseded pass stops calling providers instead of running on for a course the user has left. The remaining two are narrower. The workbench pane asks for ownership only after a document load succeeds, and after every later one, mirroring the page route: the load is what creates the ownership row the first time a course is opened, so asking beforehand asked about a course that did not exist yet and locked its author out for the mount. And the ownership gate on the timeline editor now withholds narration regeneration alone; listening back to existing narration and seeing whether a line has any spend nothing and stay available. Known limitation, unchanged and now stated plainly in the comments that used to point at it as a solution: nothing reclaims an unreferenced pool asset. The registry sweep is written but not wired up, and the byte collector only reclaims blobs no registry row names, so every narration regeneration and every abandoned allocation leaves storage behind. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XypYpLBtk8DB5nT5jyqZ5D * fix(media): gate asset mutations, and make claims and allocation records survive a handoff Opening the asset routes opened all of them. Reads and allocations are meant to be as open as document reads and creates already are, but no authorization hook was supplied, so the handler's default admitted PUT and DELETE too — and those scope by principal key alone, which is one shared constant. Any caller who learned an id, and a document read hands out every id its slides name, could overwrite or destroy another author's media. Mutations now require the deployment's credential, which in a production build without the development-auth opt-in means they are refused outright; reads and allocations stay open. The route comment says what the posture is and what it is not: the deployment-level fence is the access code, and no per-principal quota is configured. The client's own reclaim is best effort to match — losing an argument about deleting an asset must not cost a task its retry, and the bytes are left for server-side reclamation. The pass claim could not survive the handoff it was written for. A retry aborts the live media pass and starts its replacement in the same synchronous block, long before the aborted pass's cleanup runs, so the replacement saw every element still claimed, collected nothing, and returned — leaving each unreached element at pending with nobody coming back for it and no retry control to recover it, which is the exact failure the claim was introduced to prevent. A claim now carries its pass's signal and is retired the moment that signal aborts, and a pass releases only claims it still owns, so a late unwind cannot take its replacement's work. Claims are also acquired at the single point every request passes through, so a single-task retry participates too — previously a retry awaiting its provider was invisible to a pass starting alongside it and both called it. The allocation record could outlive the bytes it named. It was written before the write-back attempted anything and survived the reclaim that followed a failure, so when the slide finally arrived the write boundary stamped a deleted id into the document — and the placeholder it replaced was gone, which reads as already generated and stops anything from retrying. The record is now written only where the allocation is retained, and forgotten wherever a reclaim removes the bytes, including the narration rollback path. The tests follow. The route test drives the real storage handler against an in-memory registry instead of a stub, so it can see what the resolved principal is then allowed to do; the handoff test performs a real abort mid-pass rather than starting from an already-aborted signal; and the guards that could only assert file layout now assert the property they care about, or have been replaced by behaviour. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XypYpLBtk8DB5nT5jyqZ5D * fix(media): make media passes serial per course instead of tracking element ownership Three rounds of per-element claims each produced a new way to lose an element. Whole-pass reservations swallowed a Retry for an element the same pass had already failed, leaving it pending with the affordance gone. Retiring a claim by its signal freed an element whose commit was still uploading, so the replacement pass paid for it twice. A claim held for a failed element stranded its retry. The bookkeeping is the defect: every refinement of "who owns this element right now" answered the question at a moment when the answer was already stale. Passes for one course are now serial. A replacement aborts its predecessor, as before, and then waits for it to settle before collecting. That removes the question entirely: a commit already under way finishes — its bytes stored and its reference written, so the new pass sees a resolved slide and skips it — and an element the aborted pass never reached is still a placeholder and gets collected like any other. The claim set, the reservations, the signal retirement and the identity-checked release are all gone. The task table is consulted for one thing only: an element that is generating right now is a single-element retry running alongside the pass, and taking it too would pay twice. Pending is deliberately not a skip reason — it means a pass once intended to reach an element, which an abandoned pass leaves behind with nobody acting on it, and reading that as answered is what stranded elements before. A retry runs concurrently with a pass, because a pass never revisits an element it has processed, and it re-reads the task after its own await and refuses before touching it: marking first and refusing afterwards destroyed the failed state that draws the affordance. Browser-only mode is back to exactly what it was. The abort is now conditional, the waiting does not apply, and the original status-based skip is restored verbatim. Two baseline lines remain changed in each of the two files, and both are behind a server-backed fork whose else-branch is the original. Two smaller things. The allocation record becomes visible when a write goes on the wire rather than when the round trip ends, and the write boundary reconciles under the document lock rather than before it — a save queued during a write-back was otherwise captured with the placeholder and, for a course the user had left, had no corrective flush to follow. And the comments that said a refused reclaim leaves its bytes for server-side reclamation were wrong: nothing collects them, because the registry entry still names its blob and the sweep that would remove it is not wired up. They now say the bytes leak. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XypYpLBtk8DB5nT5jyqZ5D * fix(media): make a deferred pass re-earn its right to run, and bound the commit it waits on Serializing passes moved their body out of the block that launched them, and three things followed from that. A pass now wakes when its predecessor settles, which can be after the user has left the course. It enqueued before it looked at its signal, into a task table keyed by element id alone — and placeholder ids are not unique across courses, which is why the classroom clears that table on arrival. So a departing course's pass seeded the arriving course's table with tasks carrying the wrong stage id, and a Retry routes by that id: the reference went into the wrong document. A pass now re-validates after the wait, before touching anything shared. The same lateness broke the skip test. `documentSkipIndex` answers only while the live store is on the pass's stage, and returning nothing put the collection loop on the browser-only rule — a silent demotion from "the document is the authority" to "this browser's task table is", on exactly the path where that table has just been cleared. Every element the predecessor had committed was collected again, paid for again, and its second write-back found no placeholder to rewrite, so its bytes were parked where nothing will ever reference them. In server-backed mode an unreadable document now means the pass stands down. And waiting was unbounded. A commit is uncancellable: the asset client takes no signal, and a document write cannot be half-undone. One stalled upload therefore froze the course's media generation for the session — the replacement never collected, the element sat on a skeleton that draws no Retry, and only a reload recovered. The pass's signal is now threaded into the media proxy fetch, and the commit is bounded by a deadline. The deadline is on the wait, not the work: the commit carries on, and if it lands late the document simply ends up correct, while the element becomes retryable and the queue moves on. The tests that were meant to pin the previous round were not sensitive to it. Two asserted end states where the mechanism only changes ordering, and one of them rigged the document read so the assertion held whether or not the pass had waited; a third covered half of what it claimed. They now observe the ordering directly — nothing is issued while another pass for the course is working; in browser-only mode a second pass reaches its provider immediately — and the reconciliation under the document lock has a test that fails when it moves back outside it. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XypYpLBtk8DB5nT5jyqZ5D * revert(media): drop the commit deadline and the abortable download The deadline bought less than it cost. Abandoning a commit after two minutes makes the element retryable while the real commit is still running, so a Retry starts a second commit for the same placeholder against the first: two provider calls, two allocations, and whichever lands second stamps its result over the other's task by element id. The allocation record is keyed by placeholder, so the loser's cleanup erases the winner's record, and the write boundary then puts the raw placeholder back into the document. That is the overlap serial passes were built to remove, reopened through the one door serialization never covered. So a stalled commit holds the course's media queue until it settles or the page is reloaded, and that is written down rather than papered over. The wait is unbounded on purpose: every ceiling on it turns out to be a way of running two commits for one element. Threading the pass signal into the download was also a mistake, in the other direction. The provider call that produced the URL has already been billed, so cancelling the download throws away work that is paid for — and the shared proxy cache records a cancelled request as a transient failure against that URL, which after three of them blocks it for every consumer in the session. Browser-only mode never asked for this: it had no way to observe an abort there, which is exactly why the bytes were kept. The signal is gone from the download again, and `fetchAsBlob` is byte-for-byte what it was before this branch. The regression guard for the stranded-element rule is restored alongside the timing test that was meant to supersede it. It catches a different rule — a task left pending being read as answered — and nothing else does: making the pass skip pending leaves every other suite green. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XypYpLBtk8DB5nT5jyqZ5D * fix(media): stop asking the pool for refs it never issued, bound it, and adopt cached bytes Four things a deployment found once this was running for real. A reference this application mints itself — a generation placeholder, a derived narration key — was never in the pool, because the pool allocates every id it holds. Asking anyway used to be an IndexedDB miss; once the pool is server-backed it is a request that answers 404, one per element per load, forever on a course that still holds placeholders. Every lease and probe now checks first. The check is a negative test on shapes this application owns, not an id validator: the pool's id domain stays unconstrained, and anything that is not one of ours is still asked about. The asset store can bound how much one principal holds, and enforces it inside the write transaction, but nothing ever passed the number. It does now, with a default rather than an opt-in: allocation is reachable by any caller a deployment admits, and with one shared principal an unbounded store is unbounded database growth with no operator-visible brake. Refusing asset mutations to unauthenticated callers was not enough, because every authenticated caller resolves to that same shared principal — so authentication decided nothing, and any signed-in visitor could delete any id they learned. Since this branch began storing media the registry is the only copy a course has. Replacing and deleting are now refused to everyone, and the browser no longer tries: an entry nothing references waits for server-side reclamation instead. What a browser must still do is forget its own record of an allocation that reached nothing, or a later save would stamp an id the document has no reason to trust. And a course generated before any of this holds placeholders in its document with its bytes only in the author's browser. Those bytes are paid for, so the author's next load converts them — stored to the pool and written back through the ordinary commit path, with no provider call — instead of buying them again. A row that records only a hosted URL is treated as absent: that URL is the provider's address, not something a document may hold. One renderer expectation moved with this. An untracked placeholder used to paint as pending on first render because asking the pool left a lease in flight; it settled to disabled a moment later either way, and now says so from the start. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XypYpLBtk8DB5nT5jyqZ5D * fix(media): surface a full store as a refusal and convert legacy narration A quota refusal reached the browser as HTTP 500 with a generic message, which reads as a transient failure: the element kept a Retry that would pay a provider again and be refused again. The store raises the contract's own error and the handler maps it to 507, but the store answering a request is not always built by the same bundle as the handler -- the persistence provider is reached from the route bundle and from instrumentation, which is why its state lives on a Symbol.for global -- and `instanceof` is false across that boundary while the declared code is still right. Classify on the code as well as the class, and make the code a permanent, persisted refusal in the browser: recorded locally so it survives a reload, shown as "storage is full", and refused by the retry entry point so a stale button cannot buy a second generation. Every other storage failure stays retryable. Convert what a pre-server-backed course still holds. Generated media is adopted under either key this application has used for it -- the placeholder, and the allocated id of a course converted once and later rolled back -- instead of only the first. Narration is converted by a load-time pass over the open course's speech actions, since nothing re-enters generation for an action that already has an id: bytes to the pool, id written back through a funnel that mirrors the media one, owner-only and server-backed-only. A line whose bytes are in no browser is left alone rather than re-synthesized. Also: the pool guard is now a positive `ast_` test rather than an enumeration of the shapes we mint (imports never reach the pool, so this is safe in both modes); the slide ref collection is an exported pure function so its four lease sites are covered behaviourally; ASSET_QUOTA_BYTES treats every spelling of zero as opting out and refuses a malformed value at startup instead of falling back; the abort signal is re-checked after the cache read, before an uncancellable commit; and the unused `removeAsset` and pool `replace` surfaces are gone.

Same contract, stricter recognition, no API change: a patch. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XypYpLBtk8DB5nT5jyqZ5D * fix(media): make a full store recoverable and adoption course-safe Narration adoption read the local audio row by its derived key alone. That key carries no stage id and the table is keyed by id alone, so two courses can mint the same one -- a PPTX import numbers its scenes and actions deterministically, which gives every imported deck's first slide `tts_s1_speech-scene-p1`. Locally a collision only means one course plays another's clip in one browser; adopting it wrote that clip into the shared document permanently, for every device and every visitor. A row that names a course is now adopted only into that course, and a row from before that column existed only when the text it recorded is the text of the action being converted. A full asset store was made permanent last round, which was wrong three times over: it overwrote the refused bytes with an empty blob -- on the conversion path that row is a course's only copy of its own media -- it kept sending the rest of the deck to a provider against a ceiling it already knew was reached, and it left no way back once an operator raised that ceiling. A full store is neither the content's fault nor the configuration's, so it is now its own case: the bytes are kept, the pass stops at the first refusal, and the element shows the reason together with a Retry that re-attempts the upload from those bytes. Nothing retries automatically, so no one is re-billed. The narration write-back now reaches the write boundary every producer of a durable write passes through, not only the dirty mark: adoption never deletes the derived row, so a snapshot that reverts the rewrite is adopted again on the next load and allocates a fresh asset every time. Adoption is also mounted by both classroom surfaces rather than one, takes the course's abort signal, and re-validates that this browser still has the course open before each write. ASSET_QUOTA_BYTES is validated from instrumentation, where the README and the docstring already claimed it was: its only other consumer is lazy and memoised, so a malformed ceiling let the process boot and then failed every persistence request, documents and runtime included. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XypYpLBtk8DB5nT5jyqZ5D * fix(media): remember a full store per course, and never lose retained bytes A stopped pass left the elements it never reached as placeholders with no persisted record -- deliberately, since nothing was attempted for them. But that left the next load with no reason not to try: it called a provider for the next placeholder and was refused at exactly the same point, once per reload, indefinitely. A full store is not a property of any slide. It belongs to the deployment and changes for reasons the document knows nothing about, so it is now remembered once per course in the browser's device KV. A pass that finds the marker stands down before spending anything and leaves every placeholder its "storage is full" state and its Retry; the first upload that succeeds clears it and the next pass runs normally. Narration adoption latched per course so it runs once per load, and the latch outlived the abort that leaving a course performs. On a surface that stays mounted across switches -- the workbench pane is one component for every course it shows -- owner course A, visitor course B, then back to A skipped exactly the clips the abort had cut off, and nothing else converts them. The latch is released with the abort now, and a course adopts one run at a time so a re-entry cannot hand a clip a second allocation while the previous run's uncancellable tail is still settling. A quota-blocked element retried into a network error or a 500 lost the bytes that were kept for it: the retry deleted the row before attempting the upload and wrote no replacement for an error carrying no structured code, so the next retry went back to a provider for media this browser had a moment earlier. The row now survives until an upload succeeds, the failure handler keeps whatever bytes the attempt was given, and the retry asks the question a pass asks -- does this browser already hold bytes for this element -- rather than reading an error code that a second failure has already overwritten. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XypYpLBtk8DB5nT5jyqZ5D * fix(media): adopt real legacy narration, queue re-entries, report attempt outcomes Narration adoption admitted a stage-less row only when the text it recorded matched the action being converted. Both of those columns were added to the local audio table by the very change that moved narration onto allocated ids, so a row still carrying a derived key has neither: the rule refused every real pre-allocation course and passed only on fixtures built from post-allocation rows. What the row cannot say, the key can. A derived key names two clips only when two courses share a scene order and an action id, and an action id repeats only when something other than the generator minted it -- an import numbers them by slide position. So a key built from a generated action id is adopted on that basis, a key an import could have reproduced still needs matching text, and a row that names another course is refused however unique its key looks. Handing a re-entering caller the adoption run already in flight undid the latch release it was paired with: that run is bound to the signal the departure just aborted, so it stops at its next clip while the caller -- which has the course open and a live signal -- is told the work is done, and an effect replayed as mount, cleanup, mount adopts nothing at all. A later caller now waits for the uncancellable tail and scans again, which costs a lookup on a course that has nothing left and finishes the clips the abort cut off on one that does. One attempt at an element now reports both facts its callers need instead of a bare boolean: whether the store refused it for room, and whether bytes actually reached the store. Leaving a course clears the task table, so a retry that landed afterwards read "no failed task" as success and deleted the row holding the only copy of the media. Nothing is inferred from that table any more. Reading the localStorage property can throw where storage is denied by policy, typeof included, so the availability check moved inside the guard: this metadata is best-effort, and a rejection here strands a generation pass that has already enqueued its tasks. A retry is never blocked by the per-course "store is full" marker, but a retry that is refused again re-sets it, and adoption now reads and writes the same marker rather than issuing one refused upload per clip on every load. The two canvas element renderers and both thumbnail renderers show the reason beside the Retry, so a full store does not look like an ordinary failure. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(media): probe a full store instead of standing down, and pair notices with a Retry Narration adoption was given both halves of the per-course "the store is full" marker last round: it stood down when the marker was set, and it set the marker when its own upload was refused for room. Those halves are only safe together if something can lift the marker, and for adoption nothing could. It has no affordance of its own, it stood down before reaching its own clear, the media pass returns before its marker gate when there is nothing to generate -- so a narration-only deck, or one whose slides are already satisfied, painted no storage-full element and offered no Retry -- and narration generated rather than adopted allocates directly rather than through the media commit. The course's cached narration was then lost for good, where before it converted on the first load after the ceiling was raised. The gate is a probe now. A marked course attempts exactly one clip per load: refused, it stops and the marker stands, which costs what standing down cost; stored, it lifts the marker and finishes the course. Adoption spends no provider money, so the whole cost of probing a store that is still full is one refused upload. Generated narration lifts the marker too. The three surfaces that gained a failure notice last round drew it for any failure with a reason, including the one refusal that is reachable without server-backed persistence, so a browser-only deck painted something it had not painted before. The notice is drawn beside a Retry and nowhere else, which is what it was added for and what leaves browser-only output unchanged. Both are now asserted through the render harness the surface matrix already had. A caller arriving while a rescan is queued shares it rather than appending another. One rescan converts whatever the run in flight left and every later one would find an allocated id on every action, so a chain bought nothing and turned a single stalled upload into a course that never adopts again. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(media): treat a refusal for room as a fact about one clip, not the deck The asset store checks each write against the headroom it has left, so a store that refuses a long opening clip can still hold every short clip behind it. Narration adoption assumed the opposite: it broke the deck at the first refusal and then re-attempted that same first clip on every later load, because the document names it first. A deck whose longest clip exceeds current headroom therefore never converted the clips that would have fit, with no affordance to recover it -- the state the probe was introduced to remove, reached through a narrower door. An unmarked load now attempts every clip, skipping the ones that do not fit, and remembers the condition only if the load ends with clips it still could not store. A marked load spends its single upload on the smallest clip left rather than the first one named: that is the clip that answers the question the marker asks, because if the smallest does not fit nothing does. The media pass keeps stopping at its first refusal, and for a reason adoption does not share -- every element it attempts costs a provider call. A rescan several callers share took the newest caller's signal, and the newest caller is not necessarily the one still there: a surface that opened a course and closed it again would stop work a surface still showing that course was waiting for, and that surface is latched, so it would never ask again. The shared run now takes a signal that is aborted only once every caller has left. The comment claiming the shared rescan contains a stalled upload was wrong -- the rescan is chained off the run in flight, so a stalled upload leaves every caller pending exactly as a chain would. It claims the bounded queue it actually provides, and the stall is recorded as a limitation. The failed-state containers took their stacking classes unconditionally, so markup differed in browser-only mode even though nothing moved on screen. Those classes are applied only when there is a notice to stack, and the tests assert the exact class attribute rather than a substring. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(media): stop narration adoption writing the media pass's store-full marker The marker means "do not call a provider for this course". A path is entitled to write it only if its own refusal cost a provider call, and narration adoption's refusals cost nothing: it uploads bytes this browser already holds. The store also checks each write against the headroom it has left, so a clip that does not fit says nothing about whether a slide's image would. Adoption was writing it anyway, and one over-long narration clip was therefore enough to stand a course's entire image pass down on every later load -- on a store that had just accepted adoption's other clips. The author could still recover each element by hand, every load, for ever. Three rounds of narrowing this seam produced a finding each time, so it is removed rather than narrowed again. Gone: the marker read, the single-clip probe, the smallest-clip selection, and the up-front read of every row into an array -- which also retires a sampled-then-stale flag and the retention of a whole deck's blobs for the length of a run, and returns the loop to streaming one row at a time. Adoption's rule is now that every load attempts every clip it holds, once; any failure skips that clip and the load continues. The noise the coupling was meant to avoid does not arise, because after the first load the clips still outstanding are exactly the ones that did not fit -- normally none, or one. A successful write still clears the marker, and that is a different kind of statement: a write that went through is a fact this run established, where a refusal is an inference about what some other write would cost. For a course whose media needs nothing, adoption and generated narration are also the only paths that can establish it. The failure module still documented the deck-wide premise this contradicts. It now says what is true: the check is per write, and the media pass stops the deck as a judgement about cost rather than about certainty. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(media): bound a full store's cost from the store's own arithmetic Removing the store-full marker from narration adoption removed its bound too, and the code then asserted the bound was unnecessary. It is, on a store with room for most of a deck. On the store the whole mechanism exists for -- the ceiling reached, nothing fitting -- the outstanding set after every load is the entire deck, so a thirty-clip course posted thirty full blobs on every load, indefinitely. Each of those is not a cheap refusal: the bytes are uploaded, the server hashes the whole payload, and only then takes a per-principal lock and sums every entry that principal owns before saying no. The bound needs no flag, no key and nothing carried between loads. The store asks whether `used + addedBytes` exceeds the ceiling, and `used` only grows while a run is uploading, so a clip refused for want of room implies every clip at least that large is refused for the rest of that run. The run keeps the smallest size it has been refused and skips anything no smaller without uploading it; a smaller clip is still attempted, because it may fit. A deck the store refuses entirely now costs one upload per successive size minimum instead of one per clip, and a deck it has room for costs nothing extra, because nothing is refused. Only a refusal for room lowers the bar: a dropped connection says nothing about how much room there is. The deck-wide certainty premise the failure module retracted last round still stood verbatim at the site that implements the stand-down. Both copies now say the same thing: the check is per write, and the pass stops the deck as a judgement about cost rather than about certainty. The comment on adoption's marker clear now names its price. Narration of a few hundred bytes fits in headroom an image does not, so a proven write can let the next pass buy one more image that is refused again -- bounded at one, and the price of the alternative being a course whose media never generates again. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * docs(media): state the adoption bound exactly, and stop three comments describing the old rule The comment introducing the in-load bound gave its cost as "at most a handful, and the first load pays the most". Neither clause is a property of the rule. A clip is skipped only when something no larger was already refused, so a fully-refused deck costs one upload per successive size minimum in document order: one when the clips grow, about ln N for an arbitrary order, and one per clip when they only shrink -- a long opener followed by terser lines is exactly that shape. And no load is cheaper than the first, because the bound resets per run and a refused clip stays outstanding. The comment now says that, and points at what would make it exactly one for any ordering: the store returning its remaining headroom in the refusal's existing details channel, which the server leaves empty today. Two other comments still described the previous rule -- "attempts every clip it holds, every load" -- one of them twenty lines above the paragraph that introduces the bound, in the same block. Both now say what the code does. The bound's soundness is worth stating where a maintainer will look for it: quota is charged at full length with no discount for a duplicate, the sum it is checked against joins entries to blobs so the collector cannot lower it, the check takes a per-principal lock before summing, and replace and delete are refused to every browser. Nothing a run can do makes room appear inside it. One test installed a row implementation and replaced it wholesale a few lines later, so the first was dead and the survivor dropped the text the first clip's import-shaped key needs for the ownership rule -- it passed on the coincidence that the fixture's default text is the action's. Merged into one. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(media): keep a Retry from re-buying parked media, and state the store seam once Five findings from an inline review. The standalone classroom route asked the ownership sidecar once per load and recorded only stage ownership when that ask failed. Every non-answer fails closed, so one transient 5xx left the genuine author with no resume, no Retry affordance and no legacy narration converted for the rest of the load, with nothing to change it short of a reload. The failure now records the fail-closed answer explicitly -- an answer an earlier load established must not outlive the failure that replaced it -- and an unresolved answer is asked for again, a few times over a few seconds. A real answer, however unwelcome, is final. A Retry could pay a provider for media the pool already held. When the bytes are stored and only the write-back fails in a way that keeps the allocation, it is parked and no local row exists, because that row is written only after a successful write-back. Retry now reads the parked queue exactly as the pass does and re-attempts the write-back: it re-keys the task done when the document takes it, leaves the entry parked when the slide still does not exist, and stays failed and retryable when the document refuses again. Object URLs a parked allocation owns are revoked when the entry is dropped. The commit path leaves them alone while the entry is parked, because it is then the only thing holding bytes this tab can render, so a course switch or a stage deletion was pinning the whole blob for the life of the tab. An entry a slide has already taken is left alone: the task table is displaying those URLs. The fallback lookup for cached bytes is a stage-scoped scan, and the keyed lookup misses for every row the commit path writes, so a pass was materializing and sorting the course's whole media table once per element. One scan per pass now, built on the first miss. It is sound and not merely cheaper: an element asks only for its own placeholder, and every row a pass writes carries the placeholder of the element that wrote it. "The store accepted a write, so it is not out of room" was enforced at three call sites under slightly different conditions, which made it a convention the next pool write path could silently break. It is stated once, in putAsset, for the course whose bytes it just stored.

feat(media): write generated media through the asset pool under server-backed persistence (#1392) * feat(media): store generated media in the asset pool when persistence is server-backed With server-backed persistence the document is durable and shared, but generated media stayed in the producing browser: the document kept its gen_img_* / gen_vid_* placeholder and narration kept a browser-derived audio id. Every new browser that opened such a course re-ran generation for every slide, and it never converged, because the address of the generated bytes was never written back into the document. Under server-backed persistence only, the classic generation chain now stores bytes in the asset pool first and writes the id the pool allocated into the document. - The client bootstrap configures the asset seam alongside the document and runtime seams: an HttpAssetStore over the persistence endpoint carrying the same credentials the document store carries, marked server-backed. The seam preflight now covers all three, so a failure still cannot half-configure persistence. - Image, video and TTS generation commit in one fixed order: provider, pool, document, local cache, task. A reference reaches the document only after put returned an id, so a document can never name bytes that were not stored. A failure before the write-back leaves the placeholder with the provider called exactly once; the retry happens on the next owner load. - The write-back is a per-slot rewrite through mutateDocument, which re-reads the current document under the per-stage lock, so it cannot clobber a newer scene. The open course is refreshed with the same rewrite without being marked dirty. - "Has this already been generated?" is answered by the document (the slide exists and no longer holds the placeholder) instead of by this browser's task table. - The classroom's resume effect fails closed on ownership: only a resolved owner starts generation, so a viewer opening a shared course spends nothing. - The local media and audio tables become a per-tab cache. A failed cache write costs a re-download, never the media. Browser-only mode is unchanged: every new call site sits behind the server-backed gate, the local tables stay authoritative there, and placeholders stay in the document. Rendering and export needed no changes. HttpAssetStore.resolve mints an object URL exactly as the browser store does, and the export byte resolver was already pool-first. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XypYpLBtk8DB5nT5jyqZ5D * fix(classroom): make the generation owner gate a three-outcome rule and apply it everywhere The gate refused everything but a resolved owner, which read a sidecar that answered "no ownership fact exists for this course" as a reason to block. That is the answer a deployment without the sidecar's server-side prerequisites gives for every course, and the answer a course with no ownership record gives: in both, there is nobody the operator's budget needs protecting from, and refusing strands the course's own author behind a question that can never be answered. Ownership is now four states over the sidecar's three outcomes. A definite answer splits into owner and not-owner. An absent record is its own answer, ownerless, and generation proceeds — the behaviour such a deployment had before the gate existed. Only the absence of an answer, a transport failure or a load that has not asked yet, stays unresolved and fails closed: "we could not ask" must never be read as "nobody owns this". One mapper turns a sidecar result into that state, and one predicate decides on it. The workbench classroom pane runs the same resume effect and had no ownership input at all, so a viewer opening a shared course there could still spend the budget. It now asks the sidecar once per course, in parallel with its load and feeding only the generation gate, so its read-only and edit behaviour is unchanged. The shared progressive-load policy carries the gate for it, with both new inputs required rather than defaulted so a future caller cannot omit them into an open budget. Its stale comment claiming ownership could not be expressed here is corrected. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XypYpLBtk8DB5nT5jyqZ5D * fix(media): make the write-back survive autosave, arrive before the scene does, and never leak Independent reviews of the write-back found three ways a durable document could still end up naming a placeholder, and two ways the gate that protects the operator's budget could be walked around. An autosave round captures the store synchronously and writes that capture, so a round already in flight when a rewrite landed wrote the placeholder straight back over the allocated id, and nothing marked the store dirty again to correct it. The rewrite now marks the units it changed, which leaves a corrective flush queued behind the stale one; re-saving a scene that already holds the id is idempotent, losing the id is not. Media is generated from outlines in parallel with scene content and usually finishes first, so the slide that will carry the placeholder does not exist yet and the write-back has nothing to rewrite. That was the ordinary path, not a tail case, and its result was discarded: the task was marked done, the scene was added afterwards with its placeholder intact, and a second pass in the same run could call the provider again. The allocation is now held under the placeholder — which also answers the skip test, so nothing pays twice — and applied when that scene is committed, before its first save. One complete pass now leaves no placeholder behind. A failed commit used to abandon what it had already allocated. A poster upload that failed threw away a stored video and sent the retry to submit the most expensive job in the system again; a rejected write-back left registry rows that name bytes nothing references, which the byte collector cannot reclaim because it only collects blobs no row names. A poster failure now costs the poster, and a write-back that reached nothing reclaims what it allocated. A partial write is left alone, because the document already names it. The ownership gate is fail-closed again. Treating the sidecar's 404 as permission was wrong: the client cannot tell "this course has no owner" from "this deployment told me nothing", so a visitor who opened a shared course could bill the operator. The root cause was the sidecar itself, which gated on the agent runtime although every persisted course has an owner regardless — the persistence route resolves one for every request. It now gates on server persistence, so the configuration that made 404 the universal answer has real ownership facts to report, and the gate can refuse everything but a named owner. Retry affordances answered to no gate at all. A viewer of a shared course with one failed image was shown a Retry button that called the provider. Both retry entry points and every surface that draws them now read one shared permission, so what is offered and what is allowed are the same value. Also: narration regeneration no longer pretends it can replace bytes behind a live id — the exclusivity proof that would allow it is refused by construction once references leave the browser, so it forks to a fresh id and says so; the "already generated" test lets a finished deck answer from the document alone, since scene order stops identifying an outline once slides are inserted or deleted; stored assets record a specific media type rather than a generic transfer type; the pane no longer asks the sidecar in browser-only mode; and the funnel's docstring now states what the per-stage lock actually guarantees, which is same-browser serialization and not a cross-browser compare-and-swap. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XypYpLBtk8DB5nT5jyqZ5D * fix(media): park allocations in the deciding turn, never reclaim on an ambiguous write A delta review of the write-back found the first-pass fix still had a window, and the reclamation it added could delete media the document already names. The allocation was parked after an awaited local cache write. A scene committed in that window reconciled against a registry that did not hold it yet, so the document kept the placeholder — and the entry recorded a moment later then answered the skip test as "already handled", so nothing could correct it. Parking now happens inside the write-back, in the same synchronous turn as the decision that nothing could take the reference; no await separates the live check from the park. Allocations parked by an earlier pass are handed to their slides at the start of the next one, before anything decides what still needs generating, so a held allocation whose scene has since arrived becomes a rewrite rather than an answer. Reclaiming on a rejected write was unsound: a rejection does not prove the server did not apply the write, so deleting the asset could break the scene that now names it. The funnel decides instead, and says so: it reclaims only when no store write was ever issued and nothing took the reference. Anything else is placed if its slide exists and parked if it does not, so the next pass reuses the bytes instead of paying for them again. When a write fails after part of it landed, the live store is brought up to the document before the error is rethrown — otherwise the next ordinary flush would overwrite the half that did land, with the ids deliberately not reclaimed. Parked allocations are now cleared with the course. Classic placeholders are reused across runs, so one surviving an interrupted run would be handed to a different slide of the next deck: the previous picture, on a slide whose provider was never asked. Both classroom surfaces clear the arriving course, the deletion cascade clears the deleted one, and clearing the database clears them all. Two more ways generation could start without asking the gate are closed. An overlapping pass — an outline retry re-enters generation with every outline while the first is still working — re-requested elements whose provider call was already in flight; a task that is not done is an answered request, not an unanswered one. And narration regeneration in the timeline editor called the TTS provider and allocated a pool asset with no ownership check at all; it now reads the same permission, which withholds both the per-line and whole-timeline controls and refuses the call. Finally, a pane opened during the stage-link availability gap recorded the sidecar's 404 for a course that was moments from existing and never asked again, leaving the real owner locked out of generation until it remounted. Ownership is re-fetched once the document becomes available; the gate stays closed until an answer arrives, so asking again can only open it for someone entitled to it. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XypYpLBtk8DB5nT5jyqZ5D * fix(media): make the asset routes reachable, and stale snapshots harmless A full-branch audit found that the deployment this project documents could not store a single generated asset, and that several routes into durable storage could still write a placeholder over a reference that had already landed. The persistence route sent asset requests through the development authenticator, which refuses outright in a production build that has not explicitly opted into it — and the documented server-persistence recipe produces exactly that build. Every store and every read answered 401, so images and video failed on every slide while re-billing the provider on each retry, and a narration failure stopped the deck at its first slide. Assets live in one shared partition by design, so there was never anything per-caller for that authenticator to decide: the route now resolves the asset principal itself, alongside the owner it already resolves for documents. Runtime sessions are genuinely per-learner and keep the development authenticator until real session verification replaces it. And narration that cannot be stored no longer fails its scene: the line stays unvoiced and retryable, which is what an image that cannot be stored does to its slide. Placeholders could also come back from behind. A queued autosave's snapshot, an editor-history entry replayed by an undo, the departing save a course switch flushes — each captures content at its own moment, and any of those moments can predate a write-back. Point fixes at each producer would leave the next producer to rediscover the bug, so the check lives at the write boundary every producer passes through, and the allocation record it consults now outlives the parked queue: a placeholder whose rewrite landed long ago is exactly the case it catches. Two ways generation could be lost or repeated are closed. A pass now claims the elements it will reach and releases them however it ends, so an overlapping pass stands down while an aborted one strands nothing — previously its tasks stayed `pending` and every later pass skipped them with no retry control to recover them. And the media abort controller is aborted before being replaced, so a superseded pass stops calling providers instead of running on for a course the user has left. The remaining two are narrower. The workbench pane asks for ownership only after a document load succeeds, and after every later one, mirroring the page route: the load is what creates the ownership row the first time a course is opened, so asking beforehand asked about a course that did not exist yet and locked its author out for the mount. And the ownership gate on the timeline editor now withholds narration regeneration alone; listening back to existing narration and seeing whether a line has any spend nothing and stay available. Known limitation, unchanged and now stated plainly in the comments that used to point at it as a solution: nothing reclaims an unreferenced pool asset. The registry sweep is written but not wired up, and the byte collector only reclaims blobs no registry row names, so every narration regeneration and every abandoned allocation leaves storage behind. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XypYpLBtk8DB5nT5jyqZ5D * fix(media): gate asset mutations, and make claims and allocation records survive a handoff Opening the asset routes opened all of them. Reads and allocations are meant to be as open as document reads and creates already are, but no authorization hook was supplied, so the handler's default admitted PUT and DELETE too — and those scope by principal key alone, which is one shared constant. Any caller who learned an id, and a document read hands out every id its slides name, could overwrite or destroy another author's media. Mutations now require the deployment's credential, which in a production build without the development-auth opt-in means they are refused outright; reads and allocations stay open. The route comment says what the posture is and what it is not: the deployment-level fence is the access code, and no per-principal quota is configured. The client's own reclaim is best effort to match — losing an argument about deleting an asset must not cost a task its retry, and the bytes are left for server-side reclamation. The pass claim could not survive the handoff it was written for. A retry aborts the live media pass and starts its replacement in the same synchronous block, long before the aborted pass's cleanup runs, so the replacement saw every element still claimed, collected nothing, and returned — leaving each unreached element at pending with nobody coming back for it and no retry control to recover it, which is the exact failure the claim was introduced to prevent. A claim now carries its pass's signal and is retired the moment that signal aborts, and a pass releases only claims it still owns, so a late unwind cannot take its replacement's work. Claims are also acquired at the single point every request passes through, so a single-task retry participates too — previously a retry awaiting its provider was invisible to a pass starting alongside it and both called it. The allocation record could outlive the bytes it named. It was written before the write-back attempted anything and survived the reclaim that followed a failure, so when the slide finally arrived the write boundary stamped a deleted id into the document — and the placeholder it replaced was gone, which reads as already generated and stops anything from retrying. The record is now written only where the allocation is retained, and forgotten wherever a reclaim removes the bytes, including the narration rollback path. The tests follow. The route test drives the real storage handler against an in-memory registry instead of a stub, so it can see what the resolved principal is then allowed to do; the handoff test performs a real abort mid-pass rather than starting from an already-aborted signal; and the guards that could only assert file layout now assert the property they care about, or have been replaced by behaviour. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XypYpLBtk8DB5nT5jyqZ5D * fix(media): make media passes serial per course instead of tracking element ownership Three rounds of per-element claims each produced a new way to lose an element. Whole-pass reservations swallowed a Retry for an element the same pass had already failed, leaving it pending with the affordance gone. Retiring a claim by its signal freed an element whose commit was still uploading, so the replacement pass paid for it twice. A claim held for a failed element stranded its retry. The bookkeeping is the defect: every refinement of "who owns this element right now" answered the question at a moment when the answer was already stale. Passes for one course are now serial. A replacement aborts its predecessor, as before, and then waits for it to settle before collecting. That removes the question entirely: a commit already under way finishes — its bytes stored and its reference written, so the new pass sees a resolved slide and skips it — and an element the aborted pass never reached is still a placeholder and gets collected like any other. The claim set, the reservations, the signal retirement and the identity-checked release are all gone. The task table is consulted for one thing only: an element that is generating right now is a single-element retry running alongside the pass, and taking it too would pay twice. Pending is deliberately not a skip reason — it means a pass once intended to reach an element, which an abandoned pass leaves behind with nobody acting on it, and reading that as answered is what stranded elements before. A retry runs concurrently with a pass, because a pass never revisits an element it has processed, and it re-reads the task after its own await and refuses before touching it: marking first and refusing afterwards destroyed the failed state that draws the affordance. Browser-only mode is back to exactly what it was. The abort is now conditional, the waiting does not apply, and the original status-based skip is restored verbatim. Two baseline lines remain changed in each of the two files, and both are behind a server-backed fork whose else-branch is the original. Two smaller things. The allocation record becomes visible when a write goes on the wire rather than when the round trip ends, and the write boundary reconciles under the document lock rather than before it — a save queued during a write-back was otherwise captured with the placeholder and, for a course the user had left, had no corrective flush to follow. And the comments that said a refused reclaim leaves its bytes for server-side reclamation were wrong: nothing collects them, because the registry entry still names its blob and the sweep that would remove it is not wired up. They now say the bytes leak. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XypYpLBtk8DB5nT5jyqZ5D * fix(media): make a deferred pass re-earn its right to run, and bound the commit it waits on Serializing passes moved their body out of the block that launched them, and three things followed from that. A pass now wakes when its predecessor settles, which can be after the user has left the course. It enqueued before it looked at its signal, into a task table keyed by element id alone — and placeholder ids are not unique across courses, which is why the classroom clears that table on arrival. So a departing course's pass seeded the arriving course's table with tasks carrying the wrong stage id, and a Retry routes by that id: the reference went into the wrong document. A pass now re-validates after the wait, before touching anything shared. The same lateness broke the skip test. `documentSkipIndex` answers only while the live store is on the pass's stage, and returning nothing put the collection loop on the browser-only rule — a silent demotion from "the document is the authority" to "this browser's task table is", on exactly the path where that table has just been cleared. Every element the predecessor had committed was collected again, paid for again, and its second write-back found no placeholder to rewrite, so its bytes were parked where nothing will ever reference them. In server-backed mode an unreadable document now means the pass stands down. And waiting was unbounded. A commit is uncancellable: the asset client takes no signal, and a document write cannot be half-undone. One stalled upload therefore froze the course's media generation for the session — the replacement never collected, the element sat on a skeleton that draws no Retry, and only a reload recovered. The pass's signal is now threaded into the media proxy fetch, and the commit is bounded by a deadline. The deadline is on the wait, not the work: the commit carries on, and if it lands late the document simply ends up correct, while the element becomes retryable and the queue moves on. The tests that were meant to pin the previous round were not sensitive to it. Two asserted end states where the mechanism only changes ordering, and one of them rigged the document read so the assertion held whether or not the pass had waited; a third covered half of what it claimed. They now observe the ordering directly — nothing is issued while another pass for the course is working; in browser-only mode a second pass reaches its provider immediately — and the reconciliation under the document lock has a test that fails when it moves back outside it.

Abandoning a commit after two minutes makes the element retryable while the real commit is still running, so a Retry starts a second commit for the same placeholder against the first: two provider calls, two allocations, and whichever lands second stamps its result over the other's task by element id. The allocation record is keyed by placeholder, so the loser's cleanup erases the winner's record, and the write boundary then puts the raw placeholder back into the document. That is the overlap serial passes were built to remove, reopened through the one door serialization never covered. So a stalled commit holds the course's media queue until it settles or the page is reloaded, and that is written down rather than papered over. The wait is unbounded on purpose: every ceiling on it turns out to be a way of running two commits for one element. Threading the pass signal into the download was also a mistake, in the other direction. The provider call that produced the URL has already been billed, so cancelling the download throws away work that is paid for — and the shared proxy cache records a cancelled request as a transient failure against that URL, which after three of them blocks it for every consumer in the session. Browser-only mode never asked for this: it had no way to observe an abort there, which is exactly why the bytes were kept. The signal is gone from the download again, and `fetchAsBlob` is byte-for-byte what it was before this branch. The regression guard for the stranded-element rule is restored alongside the timing test that was meant to supersede it. It catches a different rule — a task left pending being read as answered — and nothing else does: making the pass skip pending leaves every other suite green.

A reference this application mints itself — a generation placeholder, a derived narration key — was never in the pool, because the pool allocates every id it holds. Asking anyway used to be an IndexedDB miss; once the pool is server-backed it is a request that answers 404, one per element per load, forever on a course that still holds placeholders. Every lease and probe now checks first. The check is a negative test on shapes this application owns, not an id validator: the pool's id domain stays unconstrained, and anything that is not one of ours is still asked about. The asset store can bound how much one principal holds, and enforces it inside the write transaction, but nothing ever passed the number. It does now, with a default rather than an opt-in: allocation is reachable by any caller a deployment admits, and with one shared principal an unbounded store is unbounded database growth with no operator-visible brake. Refusing asset mutations to unauthenticated callers was not enough, because every authenticated caller resolves to that same shared principal — so authentication decided nothing, and any signed-in visitor could delete any id they learned. Since this branch began storing media the registry is the only copy a course has. Replacing and deleting are now refused to everyone, and the browser no longer tries: an entry nothing references waits for server-side reclamation instead. What a browser must still do is forget its own record of an allocation that reached nothing, or a later save would stamp an id the document has no reason to trust. And a course generated before any of this holds placeholders in its document with its bytes only in the author's browser. Those bytes are paid for, so the author's next load converts them — stored to the pool and written back through the ordinary commit path, with no provider call — instead of buying them again. A row that records only a hosted URL is treated as absent: that URL is the provider's address, not something a document may hold. One renderer expectation moved with this. An untracked placeholder used to paint as pending on first render because asking the pool left a lease in flight; it settled to disabled a moment later either way, and now says so from the start.

The store raises the contract's own error and the handler maps it to 507, but the store answering a request is not always built by the same bundle as the handler -- the persistence provider is reached from the route bundle and from instrumentation, which is why its state lives on a Symbol.for global -- and `instanceof` is false across that boundary while the declared code is still right. Classify on the code as well as the class, and make the code a permanent, persisted refusal in the browser: recorded locally so it survives a reload, shown as "storage is full", and refused by the retry entry point so a stale button cannot buy a second generation. Every other storage failure stays retryable. Convert what a pre-server-backed course still holds. Generated media is adopted under either key this application has used for it -- the placeholder, and the allocated id of a course converted once and later rolled back -- instead of only the first. Narration is converted by a load-time pass over the open course's speech actions, since nothing re-enters generation for an action that already has an id: bytes to the pool, id written back through a funnel that mirrors the media one, owner-only and server-backed-only. A line whose bytes are in no browser is left alone rather than re-synthesized. Also: the pool guard is now a positive `ast_` test rather than an enumeration of the shapes we mint (imports never reach the pool, so this is safe in both modes); the slide ref collection is an exported pure function so its four lease sites are covered behaviourally; ASSET_QUOTA_BYTES treats every spelling of zero as opting out and refuses a malformed value at startup instead of falling back; the abort signal is re-checked after the cache read, before an uncancellable commit; and the unused `removeAsset` and pool `replace` surfaces are gone.

Same contract, stricter recognition, no API change: a patch. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XypYpLBtk8DB5nT5jyqZ5D * fix(media): make a full store recoverable and adoption course-safe Narration adoption read the local audio row by its derived key alone. That key carries no stage id and the table is keyed by id alone, so two courses can mint the same one -- a PPTX import numbers its scenes and actions deterministically, which gives every imported deck's first slide `tts_s1_speech-scene-p1`. Locally a collision only means one course plays another's clip in one browser; adopting it wrote that clip into the shared document permanently, for every device and every visitor. A row that names a course is now adopted only into that course, and a row from before that column existed only when the text it recorded is the text of the action being converted. A full asset store was made permanent last round, which was wrong three times over: it overwrote the refused bytes with an empty blob -- on the conversion path that row is a course's only copy of its own media -- it kept sending the rest of the deck to a provider against a ceiling it already knew was reached, and it left no way back once an operator raised that ceiling. A full store is neither the content's fault nor the configuration's, so it is now its own case: the bytes are kept, the pass stops at the first refusal, and the element shows the reason together with a Retry that re-attempts the upload from those bytes. Nothing retries automatically, so no one is re-billed. The narration write-back now reaches the write boundary every producer of a durable write passes through, not only the dirty mark: adoption never deletes the derived row, so a snapshot that reverts the rewrite is adopted again on the next load and allocates a fresh asset every time. Adoption is also mounted by both classroom surfaces rather than one, takes the course's abort signal, and re-validates that this browser still has the course open before each write. ASSET_QUOTA_BYTES is validated from instrumentation, where the README and the docstring already claimed it was: its only other consumer is lazy and memoised, so a malformed ceiling let the process boot and then failed every persistence request, documents and runtime included. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XypYpLBtk8DB5nT5jyqZ5D * fix(media): remember a full store per course, and never lose retained bytes A stopped pass left the elements it never reached as placeholders with no persisted record -- deliberately, since nothing was attempted for them. But that left the next load with no reason not to try: it called a provider for the next placeholder and was refused at exactly the same point, once per reload, indefinitely. A full store is not a property of any slide. It belongs to the deployment and changes for reasons the document knows nothing about, so it is now remembered once per course in the browser's device KV. A pass that finds the marker stands down before spending anything and leaves every placeholder its "storage is full" state and its Retry; the first upload that succeeds clears it and the next pass runs normally. Narration adoption latched per course so it runs once per load, and the latch outlived the abort that leaving a course performs. On a surface that stays mounted across switches -- the workbench pane is one component for every course it shows -- owner course A, visitor course B, then back to A skipped exactly the clips the abort had cut off, and nothing else converts them. The latch is released with the abort now, and a course adopts one run at a time so a re-entry cannot hand a clip a second allocation while the previous run's uncancellable tail is still settling. A quota-blocked element retried into a network error or a 500 lost the bytes that were kept for it: the retry deleted the row before attempting the upload and wrote no replacement for an error carrying no structured code, so the next retry went back to a provider for media this browser had a moment earlier. The row now survives until an upload succeeds, the failure handler keeps whatever bytes the attempt was given, and the retry asks the question a pass asks -- does this browser already hold bytes for this element -- rather than reading an error code that a second failure has already overwritten. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XypYpLBtk8DB5nT5jyqZ5D * fix(media): adopt real legacy narration, queue re-entries, report attempt outcomes Narration adoption admitted a stage-less row only when the text it recorded matched the action being converted. Both of those columns were added to the local audio table by the very change that moved narration onto allocated ids, so a row still carrying a derived key has neither: the rule refused every real pre-allocation course and passed only on fixtures built from post-allocation rows. What the row cannot say, the key can. A derived key names two clips only when two courses share a scene order and an action id, and an action id repeats only when something other than the generator minted it -- an import numbers them by slide position. So a key built from a generated action id is adopted on that basis, a key an import could have reproduced still needs matching text, and a row that names another course is refused however unique its key looks. Handing a re-entering caller the adoption run already in flight undid the latch release it was paired with: that run is bound to the signal the departure just aborted, so it stops at its next clip while the caller -- which has the course open and a live signal -- is told the work is done, and an effect replayed as mount, cleanup, mount adopts nothing at all. A later caller now waits for the uncancellable tail and scans again, which costs a lookup on a course that has nothing left and finishes the clips the abort cut off on one that does. One attempt at an element now reports both facts its callers need instead of a bare boolean: whether the store refused it for room, and whether bytes actually reached the store. Leaving a course clears the task table, so a retry that landed afterwards read "no failed task" as success and deleted the row holding the only copy of the media. Nothing is inferred from that table any more. Reading the localStorage property can throw where storage is denied by policy, typeof included, so the availability check moved inside the guard: this metadata is best-effort, and a rejection here strands a generation pass that has already enqueued its tasks. A retry is never blocked by the per-course "store is full" marker, but a retry that is refused again re-sets it, and adoption now reads and writes the same marker rather than issuing one refused upload per clip on every load. The two canvas element renderers and both thumbnail renderers show the reason beside the Retry, so a full store does not look like an ordinary failure. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(media): probe a full store instead of standing down, and pair notices with a Retry Narration adoption was given both halves of the per-course "the store is full" marker last round: it stood down when the marker was set, and it set the marker when its own upload was refused for room. Those halves are only safe together if something can lift the marker, and for adoption nothing could. It has no affordance of its own, it stood down before reaching its own clear, the media pass returns before its marker gate when there is nothing to generate -- so a narration-only deck, or one whose slides are already satisfied, painted no storage-full element and offered no Retry -- and narration generated rather than adopted allocates directly rather than through the media commit. The course's cached narration was then lost for good, where before it converted on the first load after the ceiling was raised. The gate is a probe now. A marked course attempts exactly one clip per load: refused, it stops and the marker stands, which costs what standing down cost; stored, it lifts the marker and finishes the course. Adoption spends no provider money, so the whole cost of probing a store that is still full is one refused upload. Generated narration lifts the marker too. The three surfaces that gained a failure notice last round drew it for any failure with a reason, including the one refusal that is reachable without server-backed persistence, so a browser-only deck painted something it had not painted before. The notice is drawn beside a Retry and nowhere else, which is what it was added for and what leaves browser-only output unchanged. Both are now asserted through the render harness the surface matrix already had. A caller arriving while a rescan is queued shares it rather than appending another. One rescan converts whatever the run in flight left and every later one would find an allocated id on every action, so a chain bought nothing and turned a single stalled upload into a course that never adopts again. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(media): treat a refusal for room as a fact about one clip, not the deck The asset store checks each write against the headroom it has left, so a store that refuses a long opening clip can still hold every short clip behind it. Narration adoption assumed the opposite: it broke the deck at the first refusal and then re-attempted that same first clip on every later load, because the document names it first. A deck whose longest clip exceeds current headroom therefore never converted the clips that would have fit, with no affordance to recover it -- the state the probe was introduced to remove, reached through a narrower door. An unmarked load now attempts every clip, skipping the ones that do not fit, and remembers the condition only if the load ends with clips it still could not store. A marked load spends its single upload on the smallest clip left rather than the first one named: that is the clip that answers the question the marker asks, because if the smallest does not fit nothing does. The media pass keeps stopping at its first refusal, and for a reason adoption does not share -- every element it attempts costs a provider call. A rescan several callers share took the newest caller's signal, and the newest caller is not necessarily the one still there: a surface that opened a course and closed it again would stop work a surface still showing that course was waiting for, and that surface is latched, so it would never ask again. The shared run now takes a signal that is aborted only once every caller has left. The comment claiming the shared rescan contains a stalled upload was wrong -- the rescan is chained off the run in flight, so a stalled upload leaves every caller pending exactly as a chain would. It claims the bounded queue it actually provides, and the stall is recorded as a limitation. The failed-state containers took their stacking classes unconditionally, so markup differed in browser-only mode even though nothing moved on screen. Those classes are applied only when there is a notice to stack, and the tests assert the exact class attribute rather than a substring. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(media): stop narration adoption writing the media pass's store-full marker The marker means "do not call a provider for this course". A path is entitled to write it only if its own refusal cost a provider call, and narration adoption's refusals cost nothing: it uploads bytes this browser already holds. The store also checks each write against the headroom it has left, so a clip that does not fit says nothing about whether a slide's image would. Adoption was writing it anyway, and one over-long narration clip was therefore enough to stand a course's entire image pass down on every later load -- on a store that had just accepted adoption's other clips. The author could still recover each element by hand, every load, for ever. Three rounds of narrowing this seam produced a finding each time, so it is removed rather than narrowed again. Gone: the marker read, the single-clip probe, the smallest-clip selection, and the up-front read of every row into an array -- which also retires a sampled-then-stale flag and the retention of a whole deck's blobs for the length of a run, and returns the loop to streaming one row at a time. Adoption's rule is now that every load attempts every clip it holds, once; any failure skips that clip and the load continues. The noise the coupling was meant to avoid does not arise, because after the first load the clips still outstanding are exactly the ones that did not fit -- normally none, or one. A successful write still clears the marker, and that is a different kind of statement: a write that went through is a fact this run established, where a refusal is an inference about what some other write would cost. For a course whose media needs nothing, adoption and generated narration are also the only paths that can establish it. The failure module still documented the deck-wide premise this contradicts. It now says what is true: the check is per write, and the media pass stops the deck as a judgement about cost rather than about certainty. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(media): bound a full store's cost from the store's own arithmetic Removing the store-full marker from narration adoption removed its bound too, and the code then asserted the bound was unnecessary. It is, on a store with room for most of a deck. On the store the whole mechanism exists for -- the ceiling reached, nothing fitting -- the outstanding set after every load is the entire deck, so a thirty-clip course posted thirty full blobs on every load, indefinitely. Each of those is not a cheap refusal: the bytes are uploaded, the server hashes the whole payload, and only then takes a per-principal lock and sums every entry that principal owns before saying no. The bound needs no flag, no key and nothing carried between loads. The store asks whether `used + addedBytes` exceeds the ceiling, and `used` only grows while a run is uploading, so a clip refused for want of room implies every clip at least that large is refused for the rest of that run. The run keeps the smallest size it has been refused and skips anything no smaller without uploading it; a smaller clip is still attempted, because it may fit. A deck the store refuses entirely now costs one upload per successive size minimum instead of one per clip, and a deck it has room for costs nothing extra, because nothing is refused. Only a refusal for room lowers the bar: a dropped connection says nothing about how much room there is. The deck-wide certainty premise the failure module retracted last round still stood verbatim at the site that implements the stand-down. Both copies now say the same thing: the check is per write, and the pass stops the deck as a judgement about cost rather than about certainty. The comment on adoption's marker clear now names its price. Narration of a few hundred bytes fits in headroom an image does not, so a proven write can let the next pass buy one more image that is refused again -- bounded at one, and the price of the alternative being a course whose media never generates again. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * docs(media): state the adoption bound exactly, and stop three comments describing the old rule The comment introducing the in-load bound gave its cost as "at most a handful, and the first load pays the most". Neither clause is a property of the rule. A clip is skipped only when something no larger was already refused, so a fully-refused deck costs one upload per successive size minimum in document order: one when the clips grow, about ln N for an arbitrary order, and one per clip when they only shrink -- a long opener followed by terser lines is exactly that shape. And no load is cheaper than the first, because the bound resets per run and a refused clip stays outstanding. The comment now says that, and points at what would make it exactly one for any ordering: the store returning its remaining headroom in the refusal's existing details channel, which the server leaves empty today. Two other comments still described the previous rule -- "attempts every clip it holds, every load" -- one of them twenty lines above the paragraph that introduces the bound, in the same block. Both now say what the code does. The bound's soundness is worth stating where a maintainer will look for it: quota is charged at full length with no discount for a duplicate, the sum it is checked against joins entries to blobs so the collector cannot lower it, the check takes a per-principal lock before summing, and replace and delete are refused to every browser. Nothing a run can do makes room appear inside it. One test installed a row implementation and replaced it wholesale a few lines later, so the first was dead and the survivor dropped the text the first clip's import-shaped key needs for the ownership rule -- it passed on the coincidence that the fixture's default text is the action's. Merged into one. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(media): keep a Retry from re-buying parked media, and state the store seam once Five findings from an inline review. The standalone classroom route asked the ownership sidecar once per load and recorded only stage ownership when that ask failed. Every non-answer fails closed, so one transient 5xx left the genuine author with no resume, no Retry affordance and no legacy narration converted for the rest of the load, with nothing to change it short of a reload. The failure now records the fail-closed answer explicitly -- an answer an earlier load established must not outlive the failure that replaced it -- and an unresolved answer is asked for again, a few times over a few seconds. A real answer, however unwelcome, is final. A Retry could pay a provider for media the pool already held. When the bytes are stored and only the write-back fails in a way that keeps the allocation, it is parked and no local row exists, because that row is written only after a successful write-back. Retry now reads the parked queue exactly as the pass does and re-attempts the write-back: it re-keys the task done when the document takes it, leaves the entry parked when the slide still does not exist, and stays failed and retryable when the document refuses again. Object URLs a parked allocation owns are revoked when the entry is dropped. The commit path leaves them alone while the entry is parked, because it is then the only thing holding bytes this tab can render, so a course switch or a stage deletion was pinning the whole blob for the life of the tab. An entry a slide has already taken is left alone: the task table is displaying those URLs. The fallback lookup for cached bytes is a stage-scoped scan, and the keyed lookup misses for every row the commit path writes, so a pass was materializing and sorting the course's whole media table once per element. One scan per pass now, built on the first miss. It is sound and not merely cheaper: an element asks only for its own placeholder, and every row a pass writes carries the placeholder of the element that wrote it. "The store accepted a write, so it is not out of room" was enforced at three call sites under slightly different conditions, which made it a convention the next pool write path could silently break. It is stated once, in putAsset, for the course whose bytes it just stored.

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 the next claim sees a provider-safe transcript. * test(agent): pin the runner wiring for interruption-boundary tool repair * feat(agent): add neutral tool foundation libraries (#1184) * feat(agent): register a web_search tool on the session runner (#1185) * feat(storage): add a per-session URL trust gate (#1186) * feat(agent): add the skills system (#1189) * feat(agent): add the skills system (builtin directories and durable user skills) * 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. * fix(agent): share unstorable-character validation and align skill lookup * feat(agent): add session materials and a fetch_url tool behind the URL trust gate (#1190) * feat(agent): add session materials and a fetch_url tool behind the URL trust gate * fix(agent): harden session material fetching * feat(storage): add an ownership scope to stage documents (#1191) * feat(agent): add material read and search tools (#1192) * feat(agent): add stage read and patch tools (#1194) * feat(agent): add page generation and deck editing tools (#1198) * test(storage): keep the PG contract suite order-independent (#1200) * fix(agent): revoke deleted-session URL authority and reject private ISATAP endpoints (#1199) * fix(storage): revoke deleted session URL authority * fix(ssrf): reject private ISATAP endpoints in strict fetches * chore(storage): bump to 0.11.1 for the session-URL authority fix * feat(agent): add roster and voice registration tools (#1201) * feat(agent): add folder organisation tools (#1202) * feat(api): add stage and material HTTP routes (#1203) * feat(workbench): add the client data layer (#1204) * feat(workbench): add the client data layer * docs(workbench): write the ported comments in English * chore(edit): remove the in-editor agent panel (#1210) * chore(edit): remove the in-editor agent panel * style: apply prettier formatting * fix(agent): report the runtime as unusable without a database (#1207) * fix(agent): report the runtime as unusable without a database * style: apply prettier formatting * feat(agent): add image, video and pptx import tools (#1211) * feat(workbench): add the agent chat surface (#1205) * feat(workbench): add the agent chat surface * docs(workbench): write the ported comments in English * fix(workbench): label the folder and rename tools on the timeline * fix(workbench): label the roster and voice tools on the timeline The reconciliation test iterates every tool the runner registers and requires a display label of its own. The roster and voice-clone tools (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(agent): add the material extraction lifecycle (#1212) * feat(storage): add material extraction lifecycle * feat(agent): execute queued material extraction * style: apply prettier formatting * style: satisfy prefer-const in the extraction runner * test: give material fixtures the extraction lifecycle fields The media-tools slice and the extraction lifecycle slice were each green in isolation but never compiled together: the lifecycle made derivedFrom and extraction required on AgentSessionMaterial while the media-tool fixtures predate them. * chore: remove stray task notes * fix(workbench): label the extraction lifecycle tools on the timeline * feat(workbench): add the workspace shell (#1206) * feat(workbench): add the workspace shell * docs(workbench): write the ported comments in English * i18n(workbench): align workspace keys across locales * fix(workbench): adopt the landed data layer and label the extraction tools - replace the sibling-slice seam stubs with the real data-layer modules - drop ambient declarations now shadowed by landed files - port timeline labels for the extraction lifecycle tools from the reference - align the new i18n keys across all locales * ci: retrigger * 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. * fix: forward the freshness manifest through the owner-bound store * feat(workbench): add the Pro entry points and preserve the mode-transition semantics (#1208) * 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. * docs: keep ported comments in English and deployment-neutral * docs: announce 1.0.0 and refresh the feature overview (#1216) * docs: announce 1.0.0 and refresh the feature overview * docs: finalize 1.0.0 README after feature merge * 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. * fix(workbench): restore editor chrome, mode transition, streaming, materials, mentions, folders (#1229) * fix(workbench): wire workspace folder routes * fix(editor): restore reference workbench chrome * fix(workbench): persist composer materials and course refs * fix(workbench): preserve live reasoning frames * fix(persistence): back off failed streaming saves * chore(workbench): retire stale slice seams * test(editor): cover element pin layer * chore(storage): bump to 0.21.0 for the user-message ref/material fields * chore(editor): translate ported code comments to English * fix(agent): fence durable tool writes and consume cancel requests atomically (#1230) * fix(agent): enforce provider force-off in agent tools and scrub vendor identity from tool results (#1231) * fix(materials): serialize per-owner quota reservations and make crashed uploads reclaimable (#1232) * fix(editor): resolve dock-bar i18n keys, remove dock height drag, wire element referencing (#1233) * fix(workbench): send the opening session message exactly once with refs intact (#1234) * feat(editor): port timeline TTS preview single-flight and voice-all state latching (#1235) * fix(media): restore the reference classic media chain (#1236) * fix(import): adapt imported PPTX canvas size so decks render without overflow (#1237) * fix(editor): complete element referencing — renderer DOM contract and GenUI picking aligned with the reference (#1238) * test(providers): reconcile the provider-config vendor-token debt count after the main merge The integration line's AK/SK fallback for the managed document provider adds occurrences that main's allowlist snapshot predates. Same mixed-composition debt category the group already documents; no new vendor behavior. * test(providers): reconcile vendor-token debt counts with the integration line The main-merge brought main's neutrality-guard snapshot next to integration features it predates (media-extractor fallback chain, local voice-profile deletion semantics, the enabled-TTS helper). Same debt categories the guard already documents; counts updated to the guard's own tally and two grouped entries added. No new vendor behavior. * fix(agent): carry reasoning through the completions dialect so the thinking strip renders (#1239) * feat(skills): add Feynman and spiral curriculum methods (#1240) * feat(agent): port missing reference tools and skills (parity audit) (#1241) * feat(media): retire asset-registry wiring; media and materials follow the reference byte model (#1242) * fix(classroom): center adapted canvases in the stage and send back navigation home during generation (#1243) * feat(settings): skill management with real list, download, delete, and upload (#1244) * feat(settings): skill management section with real list, detail, and zip download * feat(skills): owner skill delete and upload across storage, API, and settings * fixup! feat(settings): skill management section with real list, detail, and zip download chore: neutralize a reference note in the settings header comment * fix(media): persist origin-independent classroom-media references from the agent runtime (#1245) * 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.

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. Co-authored-by: Claude Fable 5 <noreply@anthropic.com> * 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.

fix(ai): let LLM calls outlive undici's 300s headers timeout (#1404) * fix(ai): let LLM calls outlive undici's 300s headers timeout A non-streaming completion only receives response headers once the whole completion exists, so undici's default 300 s headers timeout bounds total generation time. Thinking models (GLM-5.x at effort=max, MiniMax M3, …) routinely exceed that on large prompts — the request then dies with "Cannot connect to API: Headers Timeout Error" at exactly 300 s and, with maxRetries 0, the scene never generates (observed on a self-hosted deployment with glm-5.2 scene generation). Route every outbound LLM request through an undici Agent with a 15-minute headers/body timeout, attached at the shared transportFetch seam so the OpenAI-compatible, native OpenAI/Responses, Azure, Anthropic-compatible and Google transports all inherit it (same lazy-import dispatcher pattern the Google proxy transport already uses). Native transports now always install the shared transport instead of only when the server injects a validating fetch. * fix(ai): harden the LLM transport timeout fallback Review follow-ups for the undici headers-timeout fix: - getLlmDispatcher(): drop the cached promise on rejection so one transient undici import/Agent failure can't brick every later call; transportFetch falls back to the base transport (no dispatcher) when the dispatcher can't be built, warning once per failure episode - bedrock: install fetch: transportFetch like every other transport - google proxy: build ProxyAgent with the same headers/body timeout budget (http/https proxies; undici's Socks5ProxyAgent drops these options for socks5://) - transportFetch no longer overwrites a caller-supplied dispatcher - tests: dispatcher failure fallback + retry, bedrock transport, caller-dispatcher preservation, google proxy budget --------- Co-authored-by: XingJia He <hexingjia@mobirit.com> | 1 天前 | |

fix(importer): convert Equation.3 OLE formulas via MTEF v3, surface degrade telemetry (#1411) * fix(importer): convert Equation.3 OLE formulas via MTEF v3, surface degrade telemetry Legacy courseware stores formulas as Equation 3.0 / MathType OLE objects whose only renderable form inside the .pptx is a WMF preview picture. The importer cannot rasterize WMF, so those formulas degraded to a hardcoded 1x1 "transparent" placeholder — actually a 50%-alpha red pixel that rendered as a pink block once stretched over the formula frame, with no way for callers to notice the content loss. - Convert `Equation.3` / `MathType` OLE objects to LaTeX: detect the progId, resolve the embedding, parse the OLE compound file (cfb) and convert its `Equation Native` MTEF v3 stream (new utils/mtef.ts) — fractions, radicals, scripts, fences, big operators with per-family limit variations, embellishments, and Symbol-font local character encodings. Slot order follows the rtf2latex2e reference implementation and real MathType streams ([main, lower, upper]), not the archived spec prose. Any failure falls back to the picture path. - Fix the placeholder constant to a truly transparent pixel; keep recognizing the legacy red one (exported isPlaceholderDataUrl). - Surface degradation instead of failing silently: optional ImportPptxOptions.onWarning receives machine-coded warnings (media-unconvertible / formula-fallback-image / formula-degraded / element-dropped) at every placeholder consumption point (image, background, shape/text pattern fills, math fallback); a throwing sink is isolated so telemetry can never fail an import. A formula whose fallback picture is also a placeholder keeps its plain text as a text element. * fix(importer): address review — LSCRIPT base duplication, one-sided fences, Symbol table, depth caps Review round on #1411 (thanks @wyuc — the fuzz safety-net validation and the adversarial constructions found what the spec-conformance rounds could not): - tmLSCRIPT: stop re-emitting a script slot as the base group (isotopes rendered as {}_{6}^{12}{12}C and the output doubled per nesting level — a 221-byte stream could OOM the worker); the base is the following sibling, so the template emits only {}_{sub}^{sup}, and a leading script no longer steals the previous atom via the trailing-script lookahead. tvLSUPER writers that emit a single slot now fall back to it. - One-sided fences: render the missing side as a null delimiter (\left. / \right.) instead of an unmatched \left — piecewise-function braces (tmBRACE var 1) produced KaTeX-invalid output that silently degraded to flat text. - SYMBOL_FONT_LATEX corrected against URW StandardSymbolsPS AFM + Adobe AGL: 0x3C/0x3E/0x5B/0x5D are literal < > [ ] (≤/≥ live at 0xA3/0xB3, now mapped, along with the rest of the Symbol operator block); 0x22/0x24/0x5C are ∀/∃/∴; added Chi/vartheta/varsigma, the phi/varphi split (0x66/0x6A), and 0x5E = \perp. Unmapped font-local bytes >= 0xA0 now flag degraded instead of passing silently. - tmLIM: variation roles were inverted — spec + rtf2latex2e eqn.c say 0 = upper limit, 1 = lower limit; single-limit writers keep their limit via the same slot fallback as the big operators. - Hardening: MAX_DEPTH = 200 nesting cap and a 64 KiB LaTeX output cap, both throwing MtefParseError (deep bombs now fail loud instead of RangeError/OOM); video poster joined the placeholder warning points. - Tests: +6 — three REAL Equation Native stream fixtures (round-tripped from a legacy deck, pinning the font-local encoding and big-op slot order), tvLSUPER single-slot, tmLIM both roles, script-nesting perf guard; fence tests now assert KaTeX renderability instead of pinning broken strings. Suite: 85. - Version 0.1.5 -> 0.2.0 (new public option/type/export + Math.degraded). Lockfile re-anchored on main with pnpm@10.28.0: only the cfb additions remain, no unrelated churn. * fix(importer): address review round 2 — tmLIM function slot, full Symbol high-half, bra/ket, cap tests - tmLIM: emit the main slot FIRST followed by the limits and inject no operator name (the reference `39.1 = limit: lower, #1 #2` puts the function in the main slot — hardcoding \lim duplicated it and glued to letter-leading main slots, crashing KaTeX with an undefined control sequence). An empty main slot falls back to \lim as a neutral base. - SYMBOL_FONT_LATEX: completed the 0xA0–0xFF block from the URW AFM (~70 positions: ∫ ∑ ∏ ⟨⟩ ∂ ∇ ⇒ ⇔ ⋅ ′ ∅ ⊆ ⊇ ∈ ∉ ∪ ∩ …). Unmapped font-local codes now throw MtefParseError instead of passing through as Latin-1 (0xF7 was an integral extender rendering as ÷ — plausible but wrong math); radicalex (0x60) and C1 controls (0x80–0x9F) also throw, taking the picture fallback. - tmDIRAC: var1 renders a bra `\left\langle L\right|`, var2 a ket `\left| R\right\rangle` per the reference (was wrapping both sides). - Embellishment records now count against the record budget (a 10 MB embellishment-only stream no longer allocates 1 GB before the output cap fires). - Tests: +6 — every cap now has its own assertion (output-length width case at 15k sibling CHARs, record-count at 20k, in addition to the existing depth test), previously-dangerous Symbol codes verified from the AFM, unmapped-code rejection, embellishment budget, tmDIRAC KaTeX-validity for all variations. Fixture claims corrected (no big-op selector in the three real streams; the reading is pinned by the spec-conformance tests). Suite: 91. * test(importer): pin 0xD6/0xF3 Symbol glyphs through KaTeX, fix big-op test title Follow-up to the round-3 review: the two glyph fixes landed without a test, the BigOp test title still named the wrong slot order, and the table comment claimed the high half was complete while unlisted positions intentionally throw.

chore(packages): publish the @openmaic/* SDK family to npm (#778) (#780) * chore(packages): publish the @openmaic/* SDK family to npm (#778) Prepares the @openmaic/{dsl,renderer,importer} family for its first npm publish, and moves the SDK packages onto the @openmaic scope. Why the scope move: the @maic org name is unavailable on npm (an unscoped `maic` package already holds the name), so @maic/* is not claimable. @openmaic matches the project name, the scope is free, and the repo already ships an @openmaic/docs package — so the SDK family now lines up with that convention. - rename @maic/{dsl,renderer,importer} -> @openmaic/* across packages, the workspace glob, the package dir, and all import sites; lockfile regenerated - renderer: add publishConfig (public, registry.npmjs.org) — was missing, so a scoped publish would default to the wrong registry / restricted access - importer: add a files allowlist (dist, README, LICENSE) and drop the fragile .npmignore blacklist that shipped src; add an exports map so ESM consumers resolve dist/index.js instead of falling back to the .cjs main - all three: add a prepublishOnly build (+ test/typecheck) guard so a publish can never ship a stale or empty dist - add a tag-triggered publish workflow with npm provenance, pinned by name to the three @openmaic packages so the vendored forks (mathml2omml, pptxgenjs) are never published Refs #778, #720 (Phase 1). * fix(packages): address cross-review on the @openmaic publish prep Cross-review (Claude /code-review + codex) on this PR surfaced: - renderer's advertised CJS entry was broken: it keeps @openmaic/dsl external and imports a runtime enum from it, but dsl is ESM-only (no `require` condition), so `require('@openmaic/renderer')` would throw ERR_PACKAGE_PATH_NOT_EXPORTED. Make renderer ESM-only: drop the `.cjs` rollup output, `main` now points at the ESM build, and the `require` conditions are removed from `exports`. (importer is unaffected — it bundles dsl, so its CJS build still works.) - prepublishOnly re-ran the test suite during `pnpm -r publish`, so a flaky test after dsl had already published gave a non-atomic partial release. Reduce prepublishOnly to a build-only guard (never ship stale/empty dist) and move the real test/typecheck gate into the workflow, before any publish. - document that an @openmaic/* tag publishes the whole family via `pnpm -r` (pnpm skips already-published versions); the tag is a release marker, not a per-package gate. Verified: dsl + renderer + importer build; renderer emits ESM only (0 .cjs), all exports entries resolve; `npm pack` ships dist + README + LICENSE with no src leak; frozen-lockfile passes. Refs #778. * style: reflow @openmaic/dsl type imports past print-width after rename The @maic -> @openmaic rename lengthened two single-line type imports past prettier's 100-col width; prettier --check flagged them. Pure formatting. Refs #778. * docs(importer): mark @openmaic/importer browser-only (cr-loop accepted limitation) codex cross-review flagged that the published @openmaic/importer throws `XMLHttpRequest is not a constructor` when loaded in a pure Node process — its rollup build is browser-targeted (`nodeResolve({browser:true})` + a browser pdf.js build). The app only consumes it client-side ('use client'), so this is by design. Document it as an accepted limitation: prominent browser-only note in the README and a `browser` field in the manifest.

feat(video-export): service-backed MP4 render + in-app one-click export (#866) (#937) * feat(video-export): service-backed MP4 render + in-app one-click export (#866) Adds the last mile of classroom video export: turning the self-contained Hyperframes project ZIP (#865) into an MP4 via an isolated render service, one-click in-app. - render-service/: standalone Node 22 + Chromium + FFmpeg container wrapping @hyperframes/producer's library API. Async job model (POST /render -> 202 jobId, GET poll, GET download, DELETE cancel). Swappable JobStore / ArtifactStore seams (in-memory + local-disk now; Redis/S3 + presigned-302 download later) so it scales horizontally without changing the HTTP contract. Concurrency + per-user guards are config knobs. - App integration: thin Next proxy routes under app/api/export-video/* (forward only, no rendering) + capability probe. use-render-video.ts uploads the ZIP, polls via runPolledTask, downloads the MP4; shared buildExportZip prefix with the existing ZIP path. Export menu gains resolution/fps/quality selectors and a progress bar; degrades to ZIP download when RENDER_SERVICE_URL is unset. - docker-compose: render-service under an opt-in "video-export" profile. - Entry is main.ts (not server.ts): the producer auto-starts its own server on :9847 when the process entry path ends with /src/server.ts. Verified end-to-end in the container: rendered a real 640s (10.7 min) classroom ZIP to a valid H.264 720p + AAC MP4 (duration matches source) in ~9.6 min (~0.9x realtime, 4-worker frame capture). Degrade path, queued-cancel + cleanup, and per-user 429 guard all exercised. pnpm check / lint / tsc / i18n pass. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * feat(video-export): global render progress store, percent+ETA UI, ring on export button (#866) Addresses two UX issues found while driving the in-app MP4 export: 1. Progress display was raw and unfriendly (showed producer's English stage strings like "Capturing frame 5130/19220") and had no time estimate. Now the menu shows only "<percent>% · about <remaining> left". ETA is computed from a recent-speed estimate (percent-per-ms over the last sample), EMA-smoothed — which tracks the render's non-uniform pace (prep -> frame capture with a 4->1 worker drop -> encode) far better than a whole-run average, and never shows a stale/rising ETA. 2. Switching scenes mid-render unmounted the export menu and lost the progress (and reset the local "already rendering" ref, allowing a duplicate submit). The whole render lifecycle now lives in a global store (lib/store/video-render.ts), so progress survives menu close / scene switch and duplicate submits are guarded by status. A persistent CircularProgress ring on the export button shows live progress whether or not the menu is open. Also fixes the progress scale: the producer reports progress as 0..100, but our HTTP contract (and success path) is 0..1 — the service now normalizes it, so the client no longer showed "2000%". - lib/store/video-render.ts: new global store owning submit->poll->download, recent-speed ETA, duplicate-submit guard. - lib/video-export-app/use-render-video.ts: thin facade over the store. - components/ui/circular-progress.tsx: lightweight SVG progress ring. - components/stage/{header-controls,video-export-menu}.tsx: ring on the export button; menu shows percent + ETA, subscribes to the store. - render-service/src/render-manager.ts: normalize producer progress 0..100 -> 0..1. - i18n: percent/ETA strings across all 8 locales (drops the stage-based string). - render-service/package-lock.json: complete integrity hashes (reproducible npm ci). Verified: ETA logic checked against the real segmented render curve (worker drop raises ETA, encode speedup drives it to ~0); progress scale fix confirmed live against the container (0.2 -> 20%). tsc / lint / prettier / i18n pass. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(video-export): persist render options in the store, not the menu component Selecting 720p/24fps/draft, switching scenes, and reopening the export menu showed the defaults again (1080p/30/standard). The selections lived in the VideoExportMenu component's local state, which reset when the menu unmounted on a scene switch — the running render still used the chosen options, but the UI misrepresented them. Move resolution/fps/quality into the global video-render store (with a setOptions action). The menu now reads/writes the store, so selections survive menu close / scene switch, and while a render runs the selectors reflect the options that render is actually using. startRender() reads options from the store instead of taking them as an argument. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(video-export): deployment correctness + resource/isolation controls (PR #937 review) Addresses the blocking findings from wyuc's review. Output fidelity was fine; these harden deployment and production resource/isolation boundaries. #1 Compose advertised MP4 but couldn't render in prod: - Capability now probes the service's /health (checkRenderServiceHealth), so a configured-but-absent service reports disabled and the UI degrades to ZIP instead of 502-ing. - RENDER_SERVICE_URL is operator-supplied trusted config, so the proxy no longer runs it through the SSRF guard — the one-command `docker compose --profile video-export up` now works without globally weakening SSRF via ALLOW_LOCAL_NETWORKS. resolveRenderServiceUrl() is now synchronous. - Client degrades to ZIP on any failed submit (not only 501). #2 Unbounded upload/queue (ZIP-bomb / DoS): - unzip.ts bounds the archive via fflate's filter BEFORE decompression: entry count, per-entry and total expanded size, and compression ratio. - Proxy rejects oversized uploads (413) by Content-Length before forwarding. - RenderManager enforces a global queue-depth cap (RENDER_MAX_QUEUE). - All limits are env-tunable knobs in config.ts. #3 Per-user guard was ineffective + admission ran after extraction: - Identity is derived server-side (client IP) and forwarded as x-openmaic-client; the service ignores any client-supplied userId, and the proxy strips it. - Admission is split into reserve()/submit()/release(): the slot is reserved BEFORE extraction, so a rejected caller never triggers a decompression. Additional risks: - Per-job wall-clock watchdog (RENDER_JOB_DEADLINE_MS) aborts + fails a hung render so it can't hold a slot/scratch forever. - Download proxy bounds only the time-to-headers, not the body stream, so large MP4s over slow links no longer truncate. - Client cancels the server job (DELETE) when a started render fails/times out. - Compose puts render-service on an internal:true network (no host/internet route), sandboxing the Chromium that runs the uploaded HTML; the export ZIP is self-contained so no outbound is needed. README documents the standalone caveat. Not closing #866: the smoke/golden-render CI acceptance criterion remains a follow-up (see PR description). Verified in-container: legal render 202; ZIP-bomb (entry-count + compression- ratio) rejected 400 before any decompression; per-identity guard 429 with a spoofed multipart userId ignored; reserve-before-extract leaves no scratch dir on rejection; watchdog aborts an overrunning job and frees the slot. tsc / lint / prettier / i18n pass; render-service tsc passes. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(video-export): real audio durations + burned-in subtitles (PR #937 review) Two export-fidelity issues found in wyuc's deeper E2E: A. Narration was scheduled from estimated durations, cutting audio off mid- sentence and advancing the timeline early. The scheduler trusted AudioFileRecord.duration (recorded only since #861), so the many existing classrooms without it fell back to text-length estimates — measured 4.35s average / 10.23s max underestimate across 47 clips. timeline-deps now probes the real duration from each narration blob via an off-document <audio> (symmetric to the existing video probe), preferring it over the stored duration, then the estimate only when no audio asset exists. Everything downstream (narration starts, scene/total duration, subtitle cues) re-derives from the corrected value in the pure compiler — no compiler change needed. B. The final MP4 had no subtitles (only H.264+AAC), and the ZIP's SRT/VTT used the same estimated boundaries. The emitter now renders a burned-in subtitle overlay: one caption box + a hidden div per cue, revealed/hidden by the paused GSAP timeline at each cue's start/end (corrected timings from A), so Chromium's frame capture bakes them in. The producer has no subtitle track of its own, so burn-in is the v1 approach. Verified: emitter unit tests + snapshot updated (subtitle overlay + toggle statements, escaped text, hidden-by-default); 82 video-export tests pass incl. the determinism red-line proxy. Rendered a synthetic subtitle project through the container and confirmed by pixel analysis that captions appear only within their cue window (2429 near-white px in the caption band at t=1.5s vs 0 at t=0.05s). tsc / lint / prettier / i18n pass. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(video-export): subtitle layout + upload/admission hardening (PR #937 review) Address the three P1 blockers plus actionable P2s from the 6a585c29 review. P1: - emit-hyperframes: stack every subtitle cue in one grid cell and toggle display:none/inline-block, so inactive cues leave the flow instead of pushing the active cue up into the slide title. Adds a multi-cue regression test the single-cue snapshot couldn't catch. - render route + service: cap the upload by actual bytes (capBodyStream), not the spoofable Content-Length; the app now streams the multipart body through instead of buffering it via formData(). maxUploadBytes is now read. - render-service: move makeProjectDir() inside the release()-guarded block so an ENOENT/ENOSPC no longer permanently leaks the admission slot; mkdir the scratch root at startup for the standalone path. P2: - config: allow RENDER_MAX_JOBS_PER_USER=0 to disable the per-identity guard. - timeline-deps: per-probe timeout + bounded concurrency so a stuck audio blob can't wedge export in "compiling" forever. - render route: only trust x-forwarded-for/x-real-ip under TRUST_PROXY_HEADERS=true; otherwise all callers share one "direct" bucket. - render-service: add vitest tests (unzip limits/traversal, reservation arithmetic, body cap, config zero-disable) and a dedicated CI job. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(video-export): sync render-service lockfile so `npm ci` passes in CI The vitest devDependency's transitive esbuild@0.28.1 (and its platform optionals) were missing from package-lock.json, so the new CI job's `npm ci` failed with EUSAGE. Regenerated the lockfile from a clean install. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(video-export): dedupe esbuild so render-service `npm ci` installs on linux @hyperframes/core pins esbuild@0.25.12 exactly, hoisting it to the top and forcing vite@8 (via vitest) to keep a nested esbuild@0.28.1 copy. npm fails to flag that nested copy's platform-specific optionals as optional, so `npm ci` tried to install @esbuild/aix-ppc64 on linux and died with EBADPLATFORM. Add an `esbuild: 0.28.1` override so a single copy is shared (satisfies tsx ~0.28 and vite ^0.27||^0.28); esbuild is build-time only, so pinning the producer's bundled build tool is runtime-inert. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(video-export): resource/isolation hardening (PR #937 round-2 review) Address the round-2 P1/P2/P3 findings (P1#1 lockfile EBADPLATFORM was already fixed by the earlier esbuild-dedupe commit; CI Render Service job is green). P1: - Admission before buffering (#2): the render service now reserve()s the slot from the header identity BEFORE parsing/buffering the multipart, so concurrent near-cap uploads are bounded by the queue depth, not just each body by the cap. - Chromium egress lockdown (#3): the producer exposes no browser-arg hook and the render shares the internal network with the app, so a container entrypoint installs an iptables egress lockdown (drop all outbound except loopback + established replies) then drops privileges. Needs CAP_NET_ADMIN (added in compose); graceful warn-and-continue if unavailable. The self-contained ZIP needs no outbound. - Default one-render bottleneck (#4): with no trusted proxy every caller is "direct", so RENDER_MAX_JOBS_PER_USER=1 throttled the whole deployment. Default compose now sets it to 0 and relies on concurrency + global queue caps. - Non-blocking bounded extraction (#5): unzipSync -> fflate async unzip (worker, off the event loop), keeping the pre-decompression filter; default expanded ceiling 1GB -> 512MB; a semaphore caps concurrent extractions; compose adds a container mem_limit. P2: - Raise the app submit timeout/maxDuration (300MB upload can't finish in 60s). - video-render store: only degrade to ZIP when the service is genuinely unavailable (501/unreachable); surface real 429/413/5xx instead of an unsolicited download. - useExportVideo dedupe guard moved to module scope so it survives the menu unmounting (no second concurrent ZIP pipeline). - .env.example: RENDER_SERVICE_URL bypasses SSRF; drop the ALLOW_LOCAL_NETWORKS note. P3: - Deadline overruns are marked failed (not cancelled). - submit() decrements the identity slot if jobs.create throws (no leak). - CI sets PUPPETEER_SKIP_DOWNLOAD; unzip tests use tiny fixtures + low env limits. Tests: render-service now 22 tests (unzip limits/traversal, admission incl. create-leak, body cap, semaphore, config); app video-export suite unchanged. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(video-export): buffer under the extraction permit + fail-closed egress (PR #937 round-3) Address the two remaining round-3 P1 boundary blockers. P1#1 — buffering was outside the gate: `bounded.formData()` materialized the whole uploaded file into memory BEFORE `extractionGate.run()`, so up to RENDER_MAX_QUEUE (20) admitted bodies could each buffer ~300MB (≈6GB vs the 4g mem_limit) before the 2-permit gate. Move the entire RAM-heavy section — formData buffering, file read, and unzip — INSIDE the permit; the queue reservation still runs first (a rejected caller consumes nothing). Requests beyond the permit wait with their body unconsumed (socket backpressure), so at most maxConcurrentExtractions bodies are buffered at once. Refactored main.ts into a testable `createApp(deps)` factory and added an integration test proving peak concurrency in the buffering+extraction section never exceeds the permits. P1#2 — egress lockdown failed open: the entrypoint warned and started normally if iptables setup failed, so /health stayed green while Chromium could reach the app. With RENDER_EGRESS_LOCKDOWN=true (default) it now FAILS CLOSED — exits non-zero if not root, iptables is missing, or the rules don't apply. Operators accepting an unisolated setup opt out with RENDER_EGRESS_LOCKDOWN=false. Added scripts/egress-smoke.sh to assert the boundary (lockdown active, loopback works, new outbound blocked). Verified: image builds; container boots as `render` with lockdown active and serves /health; fail-closed exits 1 without CAP_NET_ADMIN; egress smoke passes (outbound blocked); 23/23 render-service tests + tsc; app tsc + root prettier clean.

Key changes: - Rewrite Language Inference section in outline prompt with decision rules for foreign language learning, cross-language PDF, proxy requests, and terminology handling - Reorder pipeline: outlines before agents, so agent profiles can use the inferred languageDirective - Pass languageDirective through scene content/actions generation - Add SSE streaming of languageDirective from outline generation - Remove manual language selection UI Eval test suite: - 50 test cases covering 9 scenario types: single-language, language learning, immersive, explicit instruction, code-switching, minimal input, user profiles, cross-language PDF, locale mismatch - LLM-as-judge evaluation with configurable inference/judge models - 50/50 pass rate with gemini-3-flash-preview + gpt-4o judge - Excluded from CI (requires LLM API keys) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * chore: remove useless attributes in test case * feat: pass languageDirective to PBL, remove hardcoded zh-CN/en-US - Remove pblConfig.language field, use languageDirective from outline inference instead - Delete all Chinese prompt duplicates in pbl-system-prompt.ts, agent-templates.ts; keep English templates with languageDirective injection - Remove zh-CN/en-US branches in generate-pbl.ts (initial prompt, post-process context, welcome message) - Pipe languageDirective through scene-generator → generatePBLContent → IssueboardMCP → agent templates - Remove i18n template wrapping from PBL welcome messages in pbl-renderer.tsx and use-pbl-chat.ts; use LLM-generated content directly to avoid language mismatch when UI locale ≠ course language - Update pblConfig schema in outline prompt (remove language field) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * refactor: clean up legacy language fields, pass languageDirective through buildSceneFromOutline - Add languageDirective param to buildSceneFromOutline, combining with outline.languageNote via buildLanguageText - Remove dead types: AudienceProfile, StylePreferences, LegacyUserRequirements, SceneOutline.language - Remove Stage.language and all its propagation (storage, stageInfo, prompt-builder fallback) - Remove GenerateClassroomInput.language and job store inputSummary.language - Remove unused pdfLanguageSample from outline SSE route Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: persist languageDirective to IndexedDB, fix TTS preview and dead refs - Add languageDirective to StageRecord and stage-storage write path - Add DB v9 migration: convert legacy language locale codes to directives - Use voice.language for TTS preview text instead of dead localStorage key - Omit empty ## Language section in PBL agent prompts - Use JSON.parse for extractLanguageDirective unescape (\uXXXX support) - Remove dead i18n keys: toolbar.languageHint, pbl.chat.welcomeMessage Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> --------- Co-authored-by: Claude Opus 4.6 (1M context) <noreply@anthropic.com> | 4 个月前 |

Amazon Bedrock 快速示例:
BEDROCK_REGION=us-east-1
BEDROCK_MODELS=us.anthropic.claude-sonnet-5,us.anthropic.claude-opus-4-8
DEFAULT_MODEL=bedrock:us.anthropic.claude-sonnet-5
Bedrock 使用 AWS 环境凭证或 AWS SDK 凭证链。临时凭证可设置 AWS_ACCESS_KEY_ID、AWS_SECRET_ACCESS_KEY 和 AWS_SESSION_TOKEN,也可以使用运行环境可用的 AWS profile / role。
可选:Lemonade(本地 AI 服务商)
OpenMAIC 支持将 Lemonade 作为本地 OpenAI 兼容服务商使用,可用于 LLM、图像生成、TTS 和 ASR,不需要 API Key。
本地启动 Lemonade 后,在 OpenMAIC 中配置:
LEMONADE_BASE_URL=http://localhost:13305/v1
TTS_LEMONADE_BASE_URL=http://localhost:13305/v1
ASR_LEMONADE_BASE_URL=http://localhost:13305/v1

如果希望 OpenMAIC 服务端默认走 Gemini,还需要额外设置
DEFAULT_MODEL=google:gemini-3-flash-preview。如果希望默认走 MiniMax,可设置
DEFAULT_MODEL=minimax:MiniMax-M2.7-highspeed。
3. 启动
pnpm dev
打开 http://localhost:3000 开始学习!
4. 生产环境构建
pnpm build && pnpm start
可选:ACCESS_CODE(共享部署)
为部署添加站点级密码保护,在 .env.local 中设置:
ACCESS_CODE=your-secret-code
设置后,访客需要输入密码才能使用,所有 API 路由也会受到保护。不设置则无影响。
Vercel 部署
或者手动部署:
- Fork 本仓库
- 导入到 Vercel
- 配置环境变量(至少一个 LLM API Key)
- 部署
Docker 部署
cp .env.example .env.local
# 编辑 .env.local 填入你的 API Key,然后:
docker compose up --build
慢速网络 / 中国大陆构建加速
Docker 构建支持两个可选参数。两者默认均为空,因此上面的标准命令仍会使用 Alpine 和 npm 的上游软件源。
ALPINE_MIRROR接收不带https://的 Alpine 镜像站主机名。NPM_REGISTRY接收完整的 npm registry URL。
这些构建参数仅用于公共镜像地址。请勿在其中嵌入用户名、密码或访问令牌,因为 Docker 可能把构建参数记录到镜像元数据或构建证明中。
使用 Docker Compose:
ALPINE_MIRROR=mirrors.tuna.tsinghua.edu.cn \
NPM_REGISTRY=https://registry.npmmirror.com \
docker compose up --build
直接构建镜像:
docker build \
--build-arg ALPINE_MIRROR=mirrors.tuna.tsinghua.edu.cn \
--build-arg NPM_REGISTRY=https://registry.npmmirror.com \
-t openmaic:local .
这些参数不会加速 Docker Hub 拉取,包括 Dockerfile frontend 和
node:22-alpine 基础镜像。若这些步骤较慢,需要单独配置 Docker daemon 的
registry mirror。同一个 BuildKit builder 会在常规缓存清理前跨构建复用 pnpm
store;缓存只用于提升性能,不是正确完成构建的必要条件。
服务端持久化(PostgreSQL)
server-persistence profile 只跑两个容器:OpenMAIC 应用本体和 PostgreSQL。持久化 HTTP 服务内嵌在应用中(/api/persistence),没有独立的持久化服务。
cp .env.example .env.local
printf '\nDATABASE_URL=postgres://openmaic:openmaic-dev@postgres:5432/openmaic\nPERSISTENCE_DEV_TOKEN=openmaic-local-dev\n' >> .env.local
NEXT_PUBLIC_PERSISTENCE=1 NEXT_PUBLIC_PERSISTENCE_TOKEN=openmaic-local-dev docker compose --profile server-persistence up --build
和往常一样把服务商 API Key 填进 .env.local。之后运行时会话和课程文档都由服务端存储;设备维度的 KV 数据(包括匿名设备学习者 key 和播放进度)仍保留在浏览器中。已有的浏览器课程数据会在首次访问时逐门课程懒式迁移到服务端存储,迁移路径与浏览器持久化一致且经过校验。
NEXT_PUBLIC_PERSISTENCE 是编译期开关,会打进浏览器 bundle。启用它的构建必须部署在具备可用运行时 DATABASE_URL 和 PERSISTENCE_DEV_TOKEN 的环境中,且构建时的 NEXT_PUBLIC_PERSISTENCE_TOKEN 必须与服务端 token 一致。否则浏览器会选择 HTTP 持久化但内嵌端点返回配置/认证/初始化错误;首页会弹出持久化不可用的提示并保留原有课程列表,而不是误导性地显示空课程库。
Warning
PERSISTENCE_DEV_TOKEN / NEXT_PUBLIC_PERSISTENCE_TOKEN 不是严格意义上的密钥:NEXT_PUBLIC_ token 会被编译进公开的 JavaScript,任何访客都能提取它并指定任意 x-learner-key,从而读写所有学习者的分区和文档。它只用于把无关的网络扫描器挡在可信网络的端点之外。**该模式仅适用于 localhost 或可信网络下的单用户部署。**生产环境请将 lib/persistence/server-auth.ts 替换为真正的会话校验,由服务端身份推导学习者分区,并相应调整文档/合并/管理端的授权策略。
PERSISTENCE_POSTGRES_PASSWORD 只在数据目录为空时初始化 PostgreSQL 角色,之后再修改不会轮换已有的 openmaic-postgres 卷。一次性本地库可以直接 docker compose --profile server-persistence down -v 后换密码重启;要保留数据则需以管理员执行 ALTER ROLE openmaic WITH PASSWORD 'new-password'; 并更新 DATABASE_URL。
资产的删除/替换只移除注册中心条目,底层字节随后由离线回收器清理。本部署默认开启回收器,资产存储不会无限增长:每 ASSET_COLLECTION_INTERVAL_MS(默认 15 分钟)执行一轮,清理已解除引用超过 ASSET_COLLECTION_GRACE_MS(默认 1 小时)的字节——grace period 就是用户删除的字节实际的保留窗口,调大请谨慎。设置 ASSET_COLLECTION_ENABLED=0 可在某个进程中关闭回收。多实例部署可以在每个实例上开启(每个 blob 行在被清理前会加锁并复查,并发回收器会串行化而非竞争),也可以全部关闭后单独运行。
资产字节默认直接出站(内嵌路由把字节写入响应体)。设置 ASSET_BYTE_EGRESS=redirect 可选择间接出站:字节 GET 会在字节层支持签名(S3 支持;PostgreSQL 字节列不支持,回退为直接返回字节)时返回一个短时效的签名 S3 URL。间接出站有两个对象存储前提:bucket 的 CORS 需允许本应用来源并在签名响应上暴露 Content-Type;签名身份需持有 bucket 的 s3:ListBucket,缺失的 key 才能以 404 NoSuchKey 而非 403 返回。相关取舍见资产 HTTP 契约。
内嵌端点实现了 RuntimeStore HTTP 契约和 DocumentStore HTTP 契约。不设置 NEXT_PUBLIC_PERSISTENCE 则保持原有的纯浏览器行为。
可选:MP4 视频导出(渲染服务)
“导出视频”菜单在浏览器内构建一个自包含的 Hyperframes 项目。要把它变成 MP4 需要 Chromium + FFmpeg(Node 22),因此运行在独立的 render-service 容器中,而不在应用内。
它是可选的,通过 video-export compose profile 启动:
docker compose --profile video-export up --build
可选:MinerU(增强文档解析)
MinerU 提供更强的表格、公式和 OCR 解析能力。你可以使用 MinerU 官方 API 或自行部署。
在 .env.local 中设置 PDF_MINERU_BASE_URL(如需认证则同时设置 PDF_MINERU_API_KEY)。
可选:VoxCPM2(自托管 TTS,支持音色克隆)
VoxCPM2 是 OpenBMB 开源的 TTS 模型,支持声音克隆。OpenMAIC 自带适配器,把 VoxCPM 跑在自己机器上即可对接。
1. 部署 VoxCPM 后端。 三种部署形态,背后是同一套 OpenMAIC 适配器,在设置里切换即可。
| 后端 | 接口 | 适用场景 |
|---|---|---|
| vLLM-Omni | /v1/audio/speech |
OpenAI 兼容的语音接口,适合 GPU 服务器 |
| Python API | /tts/upload |
官方 VoxCPM Python 运行时(FastAPI) |
| Nano-vLLM | /generate |
轻量级 Nano-vLLM FastAPI 部署 |
每种后端的具体启动步骤见 VoxCPM 仓库。
2. 在 OpenMAIC 中配置。 打开 设置 → 语音合成 → VoxCPM2,选择后端类型并填入 Base URL,下方的 Request URL 预览会显示实际请求地址。

也可以通过环境变量预先配置(不需要 API Key):
TTS_VOXCPM_BASE_URL=http://localhost:8000/v1
3. 管理音色。 三种音色模式,都在 设置 → 语音合成 → VoxCPM2 → VoxCPM 音色 里。

- Auto Voice(默认):合成时根据每个智能体的人设动态生成 voice prompt,零配置。
- Prompt 音色:用自然语言描述音色,例如 "温暖的女性教师嗓音,平静而鼓励,中等音调"。
- Clone 音色:上传一段参考音频或在浏览器里录一段。音频存在 IndexedDB 中,每次合成时发给后端。

只需告诉你的 Agent 助手你想学什么——剩下的它来搞定:
- 托管模式 — 在 open.maic.chat 获取访问码,保存到配置文件,即可直接生成课堂——无需本地部署
- 本地部署模式 — clone、安装依赖、配置 API Key、启动服务——Skill 逐步引导你完成
- 跟踪进度 — 自动轮询异步生成任务,完成后把链接发给你
- 二次开发 — 引导你在 OpenMAIC 基础上做二开:基于
@openmaic/*SDK 构建自己的应用(详见 skill 内的 extend 系列文档)
每一步都会先征求你的确认,不会黑盒执行。
