ceb05adb41 feat(media): allocate generated assets through the registry (#1007 part 2, step b) (#1039)
* feat(media): establish shared asset ownership primitives

Introduce global browser asset-pool ownership, asset-reference collection, stage reclamation planning, and lease-based URL access. Carry allocated media identity through storage and generation boundaries with regression coverage.

* fix(media): enforce safe resolution across every consumer

Route image, video, thumbnail, presentation, and video-export consumers through one resolution state machine. Prevent opaque allocated or generated references from reaching render and export sinks, with fallback and ownership tests.

* fix(media): protect document-owned assets across mutations

Allocate pool bytes before compatibility writes and document commits, then roll back uncommitted generations safely. Preserve document ownership across edits, retries, imports, speech generation, scene changes, and stage deletion.

* fix(media): scope retries and tighten ownership guard

Scope retries to the target scene and slide and refuse ambiguous shared-reference mutations. Expand retry rendering coverage and keep direct pool URL resolution behind the shared lease owner.

* fix(storage): avoid nested lock during stage cleanup

Execute prepared reclamation plans against an explicitly deleted document so the compatibility cascade cannot re-enter the per-document lock. Cover deletion of stage-owned media rows even when the document has no references.

* refactor(media): confine reclamation to stage deletion

Remove inline pool and compatibility-row cleanup from element, speech, scene, and audio replacement flows. Keep whole-stage reclamation behind explicit stage ownership, preserve stage-less legacy audio rows, and document deferred document-truth sweeping.

* fix(media): close retry and resolution gaps

Restore shared source tasks after successful forks, scope retries across both whiteboard locations, and wait for parallel TTS workers before rollback. Resolve background media through import, rendering, and PPTX export paths while keeping retry controls visible over last-good bytes.

* test(media): execute the consumer safety matrix

Replace source-substring checks with resolver seam execution across all six UI consumers, stage hydration, and both exporters. Pin each rollback layer independently and harden the ownership guard against aliased pool imports.

* chore(packages): publish the additive DSL field

Bump the DSL patch version for the optional speech-action field. Keep the transitional reclamation policy app-owned and document the legitimate transaction rollback removals there.

* fix(media): make retry rollback task-safe

Delay allocation task re-keying until final document reconciliation succeeds, restore shared source tasks on failed forks, and require exact stage-whiteboard targets before falling through from a missed scene.

* fix(media): clear private assets and refresh leases

Delete the asset-pool database during the confirmed local-data wipe. Notify the app lease layer after same-id replacement so mounted consumers re-resolve current bytes without reaching into storage internals.

* test(media): pin closure safety guards

Exercise the CSS allocation boundary, unfiltered legacy-row ownership, delete-and-undo byte survival, and real distinct consumer seams. Restore the video-only manifest overwrite condition and share the direct video resolution hook across both element variants.

* test(media): narrow rollback element assertion

Narrow the reconciled slide element to an image before checking its source so the rollback regression remains type-safe under the full root compiler configuration.

* fix(media): close lease refresh races

Gate the first batch publication by unique resolved refs, then publish every replacement snapshot without mutating the prior React state object. Serialize invalidation behind pending releases, evict rejected refreshes, and register replacement observation at the pool boundary.

* fix(media): reopen pool after clear failures

Always evict the singleton once its store has been closed, including blocked and failed database deletion paths. Report blocked deletion as deferred and prove a later write uses a fresh live store.

* fix(media): isolate shared retry progress

Track forked regeneration under the selected element until it receives a fresh asset identity, leaving the shared source task and bytes untouched. Surface targeted failures through renderer task lookup and skip the redundant fork reconciliation lock.

* fix(media): close final asset retry gaps

Keep blocked asset clears fail-loud until a successful retry, with actionable settings guidance.

Clear failed shared-fork state across durable and live key spaces, and pin renderer lookups, lease publication identity, and committed-ref rollback protection.

* fix: preserve actionable retry failures

Localize the blocked cache-clear recovery hint across every supported locale and pin the deferred-error mapping.

Retain durable fork failure rows while retries run, deleting them only after successful generation so unstructured failures survive reload.

* fix(media): hydrate legacy stored video thumbnails

Home-page recent-video thumbnails regressed for legacy Dexie mediaFiles
rows keyed by gen_vid placeholders: the reworked hydration resolved the
row's bytes through the sealed resolver but never surfaced the stored
blob (and its poster) as object URLs for the preview card, so the CI
recent-video-thumbnail e2e specs found no visible element.

Hydration now materializes legacy stored video rows into blob URLs for
both the element src and poster while keeping the resolver invariants:
opaque refs still never reach a DOM src, and concrete addresses are
never blanked. Unit pins cover the seam so the vitest suite catches this
class without a browser.

* fix(media): resolve sole restored legacy video

Classroom playback restored tasks by exact document media references. Legacy gen_vid references can outlive the key used by the one persisted video row, leaving the player on a placeholder even though bytes were restored.

Select the sole completed stage video only for legacy sequential refs after exact and reconciled matches. Keep exact failures authoritative, refuse ambiguous candidates, and cover success, ambiguity, and failure precedence in unit tests.

* fix(media): scope legacy video recovery

Decide restored legacy video recovery once from the complete document and record it through the shared task lookup consumed by playback, editing, and resolved slides.

Keep ambiguous documents as placeholders, apply the same decision to thumbnail hydration, and preserve exact failure precedence.

* fix(media): exclude claimed video recovery tasks

Model restored legacy recovery as a two-pass match across document video elements and task rows. Remove tasks claimed by exact, targeted, or placeholder lookup before applying the sole-candidate fallback, and cover the ownership/cardinality matrix.

* fix(media): unify video element resolution

Centralize source, task, poster, and legacy recovery decisions for every video consumer. Ensure direct URLs win over opaque refs and play_video waits on element-targeted retry tasks.

* refactor(media): route legacy recovery through resolver

Let document-aware consumers request legacy video recovery through the unified element binding API, keeping thumbnail hydration on a single decision path.

* fix(media): preserve import refs and prefer pool bytes

Recognize unambiguous extensionless relative media addresses during classroom import. Resolve allocated export and thumbnail assets from the shared pool before falling back to lagging compatibility rows.

* fix(export): preserve concrete video sources

Route PPTX video elements through the shared media binding resolver so an unresolved opaque reference cannot replace a playable source. Complete browser and persisted-store cleanup when asset-pool deletion is deferred, while retaining distinct hard-failure behavior.

* fix(media): fork retries without exclusive ownership

Enumerate logical asset owners across every persisted document before allowing global pool replacement. Thread explicit targets through fresh-id rewrites and cover cross-document aliases plus unreadable ownership.

* fix(media): guard global asset reclamation

Share a fail-closed persisted-document liveness check between stage deletion and retry replacement. Preserve cross-document pool aliases while deleting stage-owned compatibility rows and cover enumeration failures.

* fix(media): cover complete slide asset references

Route slide media traversal through a shared mutable slot contract so backgrounds participate in export, thumbnail hydration, collection, and rewrite lifecycles. Snapshot complete surviving-document refs once per reclamation and preserve manifest-only owners while retaining fail-closed behavior.

* fix(media): preserve exclusive retry asset ids

Allow targeted retries to replace exclusively owned pool assets in place. Keep shared and unprovable ownership paths on fresh allocations, and pin production-shaped retries plus compatibility-row cleanup.

* fix(media): revalidate asset bindings at completion

Recheck repository-wide ownership before replacing generated media and fork scoped retries when exclusivity changed. Route video export selection through the unified resolver and keep concrete posters independent of task state.

* fix(media): count unflushed owners and broadcast replacements

The completion-time exclusivity proof read only the persisted document, but
slide duplication updates the Zustand aggregate synchronously and schedules
persistence behind a debounce. A retry finishing inside that window saw a
single persisted owner and replaced the bytes behind a reference the
duplicate also held. The proof now also counts owners in the live stage
snapshot when that snapshot represents the stage being retried, so an
unflushed duplicate forks instead.

Same-id replacement notifications were realm-local, so a second tab showing
the same classroom kept its lease pinned to the superseded blob URL. The
notification now travels over a BroadcastChannel; each receiving realm runs
its own observers against its own pool, so a spoofed message can at most
force a re-resolve. A missing or failing channel never fails the replacement.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

* fix(media): bind replacement listeners and spare shared audio rows

A realm that only renders never sends a replacement, so binding the channel
from the sender path left passive tabs deaf to peers. Binding now happens
where the observer is registered, when the asset-pool module loads, and the
receiving realm resolves its own pool lazily so a cleared or unavailable
pool degrades to the next resolve instead of throwing.

Observer notifications ran under Promise.all, so a rejection surfaced after
BrowserAssetStore.replace had already committed and turned a durable success
into a reported failure. They are settled individually now; the callback is
wrapped because a synchronous throw would otherwise escape before allSettled
sees the array.

audioFiles rows are keyed globally by audioId, so deleting a stage removed
the sole row for an id a surviving document still referenced — playback and
both export paths read that table directly and cannot fall back to the
preserved pool blob. Rows are now filtered against surviving references,
while a failed enumeration still withholds only the irreversible pool
removal.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

* fix(media): serve replaced bytes from the pool everywhere

Unknown survivor liveness deleted every planned audioFiles row. Those rows
are keyed globally by audioId, and playback plus both export paths read the
table directly, so losing one is as irreversible for them as removing the
pool entry. Unknown liveness now preserves the rows too, leaving bounded
garbage for a later pass that can prove exclusivity.

The earlier pool-first change covered PPTX, video collection and thumbnail
hydration but missed classroom ZIP export, which still serialized the stale
compatibility row after a lagged same-id replacement, shipping media the
classroom no longer renders.

Auditing every direct reader of the media and audio tables surfaced the same
gap in playback: speech regeneration also replaces bytes under a stable id
and does not roll the pool back when the compatibility write fails, so the
player kept serving superseded narration. It now resolves the pool first and
falls back to stored rows for legacy and imported audio.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

* fix(audio): replace exclusively owned speech clips in place

regenerateSpeechAudio accepted the action's audioId but always passed
undefined as replaceAssetId, so regenerating an exclusively owned
pool-backed clip allocated a new asset every time, rewrote the action and
orphaned the previous pool entry and compatibility row until stage
reclamation — contradicting the stable-id path generateAndStoreTTS already
implements for media.

Ownership is now established before synthesis, and the rule itself moved to
the shared reference module so media retries, poster replacement and speech
regeneration consume one implementation instead of restating it. An
exclusively owned clip keeps its id and has its bytes replaced; a shared
clip, a legacy id with no pool entry, or unprovable ownership still gets a
fresh allocation so other holders keep their audio.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

* chore(media): drop the import left behind by the ownership move

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

* fix(media): resolve audio pool-first and fence peer realms

Stable-id TTS regeneration commits replaced narration to the pool before the
audioFiles mirror write, so a failed mirror leaves the row stale. AudioPlayer
already resolved pool-first, but audioObjectUrl, collectAudioFiles and the
video timeline dependencies still read Dexie directly and would serve the
superseded clip. All allocated-audio readers now share one resolver, with
Dexie kept as the fallback for legacy and imported rows.

The exclusivity proof modelled unflushed owners in the active realm only, so
another tab duplicating the same asset during its save debounce could still
be observed as a single owner and have its bytes replaced globally. A peer's
pending state cannot be read across realms, so presence is probed instead:
any realm holding the stage forces the fork path.

A deferred asset-pool deletion no longer reloads the page. The database is
still on disk and the guidance asks the user to close the other tab and
retry, which the reload discarded. The decision moved into a shared helper so
the rule is pinned rather than living inline in the component.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

* fix(media): fail closed when presence cannot be probed

The presence helper documented that an unanswerable probe must count as a
peer, but every unavailable path — no BroadcastChannel, a constructor that
threw, a send that failed, and the window before the pool's asynchronous
binding completes — returned false, so the ownership proof cleared a single
local owner and replaced globally shared bytes in place.

Probing now returns present, absent or unknown, and only a probe that was
actually sent and went unanswered is absent; the ownership decision treats
unknown exactly like present. The pool declares its binding intent
synchronously so a probe issued during the load-time window waits for the
bind instead of concluding that presence is unavailable, and releases that
gate if the import fails.

Coverage reaches the write boundary: with presence unknown, a
production-shaped targeted retry forks to a fresh id instead of calling
replace, and the original bytes stay intact for a peer's unflushed owner.

* chore(dsl): bump to 0.6.3 after the release dedupe took 0.6.2

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

* fix(i18n): add the deferred-clear guidance to fr-FR

The locale landed on main after this branch added the key, so the alignment
check flagged it as the one missing translation.

3. Run

pnpm dev

Open http://localhost:3000 and start learning!

4. Build for Production

pnpm build && pnpm start

Optional: ACCESS_CODE (Shared Deployments)

To protect your deployment with a site-level password, set ACCESS_CODE in .env.local:

ACCESS_CODE=your-secret-code

When set, visitors see a password prompt before accessing the app. All API routes are also protected. If not set, the app works as before.

Vercel Deployment

Deploy with Vercel

Or manually:

  1. Fork this repository
  2. Import into Vercel
  3. Set environment variables (at minimum one LLM API key)
  4. Deploy

Docker Deployment

cp .env.example .env.local
# Edit .env.local with your API keys, then:
docker compose up --build

Server-backed persistence (PostgreSQL)

The server-persistence profile runs exactly two containers: the OpenMAIC app and PostgreSQL. The persistence HTTP server is embedded in the app at /api/persistence; there is no standalone persistence service.

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

Add your provider API keys to .env.local as usual. Runtime sessions and course documents become server-backed; device-scoped KV data (including the anonymous device learner key and playback position) remains in the browser. Existing browser course data is copied into the configured server store lazily, one course at a time when it is first accessed, using the same verified migration path as browser persistence.

NEXT_PUBLIC_PERSISTENCE is a build-time switch compiled into the browser bundle. A build with it enabled must be deployed with a working runtime DATABASE_URL and PERSISTENCE_DEV_TOKEN, while NEXT_PUBLIC_PERSISTENCE_TOKEN must match that server token at build time. Otherwise the browser selects HTTP persistence but the embedded endpoint returns configuration/authentication/initialization errors; the home page shows a persistence-unavailable toast and keeps the prior course list instead of misleadingly displaying an empty library.

PERSISTENCE_DEV_TOKEN and NEXT_PUBLIC_PERSISTENCE_TOKEN are not a secret in any meaningful sense: the NEXT_PUBLIC_ token is compiled into the public JavaScript bundle, fully visible to every visitor, and therefore provides no confidentiality and no user isolation whatsoever — anyone who can load the page can extract it and read or write every learner partition and all documents by choosing an x-learner-key. Its only purpose is to keep unrelated network scanners out of an endpoint on a trusted network. This is suitable only for localhost or trusted-network, single-user deployments. Before production, replace lib/persistence/server-auth.ts with real session verification that derives the learner partition from server-controlled identity, and change the document/merge/admin authorization policies as appropriate.

PERSISTENCE_POSTGRES_PASSWORD initializes the PostgreSQL role only when the data directory is empty; changing it later does not rotate an existing openmaic-postgres volume. For a disposable local database, run docker compose --profile server-persistence down -v, set the new password and matching DATABASE_URL, then start the profile again. To preserve data, connect as an administrator and run ALTER ROLE openmaic WITH PASSWORD 'new-password';, then update DATABASE_URL.

Compose cannot attach depends_on to openmaic only when this optional profile is active without also affecting the default deployment. Startup therefore relies on the embedded route's retry-on-next-request behavior while PostgreSQL becomes healthy.

The embedded endpoint implements the package's RuntimeStore HTTP contract and DocumentStore HTTP contract. Leave NEXT_PUBLIC_PERSISTENCE unset to retain the existing browser-only behavior.

Optional: MP4 Video Export (Render Service)

The "Export Video" menu builds a self-contained Hyperframes project entirely in the browser. Turning that into an MP4 needs Chromium + FFmpeg on Node 22, so it runs in an isolated render-service container rather than the app.

It's opt-in. Start it with the video-export compose profile:

docker compose --profile video-export up --build

The app auto-detects the service via RENDER_SERVICE_URL (preset in docker-compose.yml) and enables one-click MP4 rendering. Without the profile — or when RENDER_SERVICE_URL is unset — export degrades to downloading the project ZIP for local CLI rendering. See render-service/README.md for standalone setup and tuning (RENDER_MAX_CONCURRENCY, etc.).

Optional: MinerU (Advanced Document Parsing)

MinerU provides enhanced parsing for complex tables, formulas, and OCR. You can use the MinerU official API or self-host your own instance.

Set PDF_MINERU_BASE_URL (and PDF_MINERU_API_KEY if needed) in .env.local.

Optional: VoxCPM2 (Self-Hosted TTS with Voice Cloning)

VoxCPM2 is an open-source TTS model from OpenBMB with voice cloning. OpenMAIC ships an adapter; run VoxCPM on your own hardware and OpenMAIC will talk to it.

1. Run a VoxCPM backend. Three deployment styles, all behind the same OpenMAIC adapter. You toggle which one in Settings.

Backend Endpoint When to use
vLLM-Omni /v1/audio/speech OpenAI-compatible speech endpoint, ideal for GPU servers
Python API /tts/upload Official VoxCPM Python runtime via FastAPI
Nano-vLLM /generate Lightweight Nano-vLLM FastAPI deployment

See the VoxCPM repo for backend setup.

2. Point OpenMAIC at it. Open Settings → Text-to-Speech → VoxCPM2, pick the backend, and paste your Base URL. The Request URL preview confirms OpenMAIC will hit the right endpoint.

VoxCPM2 connection settings: backend selector, Base URL, model

Or pre-configure it via env var (no API key required):

TTS_VOXCPM_BASE_URL=http://localhost:8000/v1

3. Manage voices. Three voice modes, all under Settings → Text-to-Speech → VoxCPM2 → VoxCPM Voices.

VoxCPM2 VoxCPM Voices section with Auto, Prompt and Clone modes
  • Auto Voice (default): OpenMAIC generates a voice prompt from each agent's persona at synthesis time. No setup required.
  • Prompt voice: describe the voice in natural language, e.g. "warm female teacher voice, calm and encouraging, mid-pitch".
  • Clone voice: upload a short reference audio clip or record one in the browser. The clip is stored in IndexedDB and sent to your VoxCPM backend on each synthesis.

Lesson Generation

Describe what you want to learn or attach reference materials. OpenMAIC's two-stage pipeline handles the rest:

Stage What Happens
Outline AI analyzes your input and generates a structured lesson outline
Scenes Each outline item becomes a rich scene — slides, quizzes, interactive modules, or PBL activities

Classroom Components

🎓 Slides

AI teachers deliver lectures with voice narration, spotlight effects, and laser pointer animations — just like a real classroom.

🧪 Quiz

Interactive quizzes (single / multiple choice, short answer) with real-time AI grading and feedback.

🔬 Interactive Simulation

HTML-based interactive experiments for visual, hands-on learning — physics simulators, flowcharts, and more.

🏗️ Project-Based Learning (PBL)

Choose a role and collaborate with AI agents on structured projects with milestones and deliverables.

Multi-Agent Interaction

  • Classroom Discussion — Agents proactively initiate discussions; you can jump in anytime or get called on
  • Roundtable Debate — Multiple agents with different personas discuss a topic, with whiteboard illustrations
  • Q&A Mode — Ask questions freely; the AI teacher responds with slides, diagrams, or whiteboard drawings
  • Whiteboard — AI agents draw on a shared whiteboard in real time — solving equations step by step, sketching flowcharts, or illustrating concepts visually.

OpenClaw Integration

OpenMAIC integrates with OpenClaw — a personal AI assistant that connects to messaging platforms you already use (Feishu, Slack, Discord, Telegram, WhatsApp, etc.). With this integration, you can generate and view interactive classrooms directly from your chat app without ever touching a terminal.

Just tell your OpenClaw assistant what you want to learn — it handles everything else:

  • Hosted mode — Grab an access code from open.maic.chat, save it in your config, and generate classrooms instantly — no local setup required
  • Self-hosted mode — Clone, install dependencies, configure API keys, and start the server — the skill guides you through each step
  • Track progress — Poll the async generation job and send you the link when ready

Every step asks for your confirmation first. No black-box automation.

Available on ClawHub — Install with one command:

clawhub install openmaic

Or copy manually:

mkdir -p ~/.openclaw/skills
cp -R /path/to/OpenMAIC/skills/openmaic ~/.openclaw/skills/openmaic
Configuration & details
Phase What the skill does
Clone Detect an existing checkout or ask before cloning/installing
Startup Choose between pnpm dev, pnpm build && pnpm start, or Docker
Provider Keys Recommend a provider path; you edit .env.local yourself
Generation Submit an async generation job and poll until it completes

Optional config in ~/.openclaw/openclaw.json:

{
  "skills": {
    "entries": {
      "openmaic": {
        "config": {
          // Hosted mode: paste your access code from open.maic.chat
          "accessCode": "sk-xxx",
          // Self-hosted mode: local repo path and URL
          "repoDir": "/path/to/OpenMAIC",
          "url": "http://localhost:3000"
        }
      }
    }
  }
}

Export

Format Description
PowerPoint (.pptx) Fully editable slides with images, charts, and LaTeX formulas
Interactive HTML Self-contained web pages with interactive simulations
Classroom ZIP Full classroom export (course structure + media) for backup or sharing

Offline / intranet classrooms: When you export a classroom (.maic.zip) or a Resource Pack, OpenMAIC inlines the external assets referenced by interactive scenes (KaTeX, Three.js incl. three/addons, Tailwind CDN, Google Fonts, images) into the exported HTML as data: URIs. The exported course then plays fully offline after import into an air-gapped/intranet instance — no public CDN is contacted at playback time. Assets that can't be fetched at export time (e.g. CORS-restricted image hosts) are reported and left as URLs. Classrooms exported before this feature still reference CDNs and must be re-exported to gain offline support.

And More

  • Text-to-Speech — Multiple voice providers with customizable voices
  • Speech Recognition — Talk to your AI teacher using your microphone
  • Web Search — Agents search the web for up-to-date information during class
  • i18n — Interface supports 7 languages: Chinese (Simplified & Traditional), English, Japanese, Russian, Arabic, and Portuguese (Brazil)
  • Dark Mode — Easy on the eyes for late-night study sessions
