a8726ec4f3 feat(media): add OpenRouter image and video providers (#1356)
* feat(media): add OpenRouter image and video providers

OpenMAIC ships six separate video providers (Veo, Kling, Seedance,
MiniMax, Grok, HappyHorse) and seven image providers, each needing its
own key. OpenRouter fronts those same model families behind one key and
one account, so this adds it as a provider on both sides.

Both use OpenRouter's dedicated media endpoints, not chat-completions:

- Image: POST /images -> { data: [{ b64_json }] }
- Video: POST /videos -> 202 { id, status }, poll GET /videos/{id},
  then GET /videos/{id}/content for the mp4 bytes

The model list is fetched live from GET /images/models and
GET /videos/models through /api/openrouter-models rather than pinned in
the registry: OpenRouter hosts 48 image and 28 video models today and
adds more, so a hardcoded shortlist would decide for the operator which
models exist. The registry keeps a three-entry seed as an offline
fallback, and the existing custom-model UI still accepts any model id.
Both catalogs answer unauthenticated, so the picker fills before a key
is pasted; a key is forwarded when present for proxied base URLs.

Adapter contracts are covered by stubbed-fetch tests (request shape,
empty-response handling, and the video job state machine including
terminal failure). No test performs a billable call.

Closes #1355

* fix(media): validate the key and tolerate a pasted endpoint URL

Three fixes found while configuring the new provider:

1. Both connectivity probes hit the model catalogs, which answer 200
   unauthenticated — so "Test Connection" reported success for any
   string, including an invalid key. Probe GET /key instead: equally
   cheap, and it actually rejects a bad key.

2. The settings field is labelled "Base URL" but the panel echoes it
   back as "Request URL", so pasting the full endpoint
   (https://openrouter.ai/api/v1/images) is the natural mistake. That
   built /api/v1/images/images and 404'd. Trim a trailing slash and a
   trailing /images or /videos so both forms work; a proxy path that
   merely contains the word is left alone.

3. The image and video settings panels read `data.message` on a failed
   test, but failures answer with `error` (apiError) and only successes
   carry `message`. Every failing connectivity test — for any provider,
   not just OpenRouter — rendered "connection failed: undefined" instead
   of the reason. Pre-existing; surfaced by 1 and 2 above.

Closes #1355

* fix(media): make every OpenRouter model selectable, and always select a provider

Two gaps found while configuring the new provider.

The settings Models list is a read-only catalog for every provider; the
actual model picker is the media popover. That picker built its groups
from the static registry array, so OpenRouter offered only the
three-entry seed while settings listed the full live catalog — the
models were visible but not choosable. Feed the same live catalog into
the popover, fetched only once the provider is usable so an
unconfigured install makes no request.

Separately, `imageProviderId`/`videoProviderId` are empty until a
provider is chosen (first-run auto-config leaves them blank when the
server reports no media provider). Opening the settings panel on an
empty id selected nothing: the header rendered the missing name key as
"settings.undefined", and Test Connection posted a blank
x-image-provider/x-video-provider, so it failed with "No image/video
provider configured" whatever key was typed. Fall back to the first
catalog entry so the panel always has a selection. Pre-existing and not
specific to OpenRouter.

Closes #1355

* fix(tts): request a browser-playable format from custom providers

`generateOpenAITTS` serves every custom OpenAI-compatible TTS provider but
never sent `response_format`, so it inherited whatever each provider
defaults to. OpenAI defaults to mp3; OpenRouter's /audio/speech defaults
to raw `pcm`. The unknown content type then fell through to the `'mp3'`
default below, the client built `data:audio/mp3;base64,…` from headerless
PCM samples, and playback failed with "no supported source was found" —
while the server logged a clean 200, because the audio really was
generated. Name the format instead of inheriting it.

Also stop mislabelling an unrecognised body: `pcm`/`l16` now raises a
message naming the cause, and `aac`/`opus` are recognised.

Two supporting fixes:

- /api/openrouter-models normalises its base URL the way the adapters do
  and falls back to the public catalog when a custom base URL fails, so a
  typo in a free-text settings field cannot empty the model picker. Also
  types the headers object so tsc accepts the conditional.
- provider-neutrality-guard pins exact per-vendor occurrence counts in
  lib/server/provider-config.ts. Adding the image and video env entries
  raises "openrouter" from 2 to 6 (each entry contributes both its key and
  its value); CI failed without the bump.

Closes #1355

* fix(security): never send the operator key to a client-chosen host

Review found `/api/openrouter-models` was an SSRF and key-exfiltration
path, and the finding is correct. The route took `x-base-url` from the
caller at highest precedence while preferring the *server* env key, so any
caller could make the server send the operator's OpenRouter credential as
an `Authorization: Bearer` header to an arbitrary URL. The route's own
comment claimed it followed `/api/verify-image-provider`; that pattern
runs `validateUrlForSSRF` on client base URLs, and this route did not.

The boundary is now explicit: the server key travels only to the
operator's own base URL. A client-supplied URL is SSRF-validated and
carries only that caller's own `x-api-key` — the server key is dropped —
and the unauthenticated public-catalog fallback never forwards a
credential chosen for a different host. Redirects are no longer followed
(`redirect: 'manual'`), since a redirect would carry the Authorization
header off-host and reopen the same hole, and upstream reads are bounded
by a timeout.

The per-URL cache is now keyed by destination *and* a hash of the
credential, and bounded to 64 entries with oldest-first eviction, so
client-supplied URLs cannot grow it without limit and one caller's
key-authorised catalog is never served to another.

Also from the review:

- The image adapter discarded the reported `media_type`. The
  orchestration layer wraps a bare `base64` as `data:image/png`
  unconditionally, so jpeg/webp results were mislabelled; the adapter now
  returns a data URL carrying the real type.
- Adapter generation and poll requests set `redirect: 'manual'`, matching
  the `/key` probe that already did.
- `runPolledTask` accepts an `AbortSignal` so the sleep between polls is
  cancellable; the video adapter passes the caller's signal. Without it a
  cancelled generation still slept out a full 10s interval.

Tests cover the highest-risk paths the review named: which credential
reaches which URL, that an SSRF-rejected destination is never contacted,
that the fallback is unauthenticated, cache isolation between callers,
and MIME preservation.

Findings 2 (base-URL normalisation) and 4 (neutrality-guard debt) were
already fixed in d553a08, pushed after the review was submitted; CI is
green on that commit.

wyucandClaude Opus 5 2cbd011c1f feat(token-plan): add TokenDance one-key preset for every modality (#1525)
* feat(token-plan): add TokenDance one-key preset for every modality

TokenDance is a model gateway: chat and images are OpenAI-compatible at
/gateway/v1, and the same key authenticates vendor-protocol routes on the
same host (Ark, MiniMax, Bocha). The preset reuses the existing adapters
with those route prefixes as base URLs, so one key lights up LLM, image,
video, TTS and web search from Settings -> Token Plan.

- providers: add a built-in `tokendance` OpenAI-compatible provider
  (TOKENDANCE_* env prefix, logo, provider name in all locales)
- token-plan: add the TokenDance preset (Seedream image, MiniMax H3 video,
  MiniMax speech TTS, Bocha web search)
- seedream: use a base URL that already ends in a version segment verbatim,
  so gateway routes like `/ark/v3` do not get `/api/v3` appended
- minimax-video: route H3-family models through the v2 task API (content
  array submit, task-envelope poll); connectivity checks for H3 probe auth
  on the v2 query route instead of submitting a billable task
- README: add a one-key quick example and replace the Gemini-specific
  model recommendation with a provider-agnostic setup recommendation

* fix(token-plan): accept preset web-search base URLs and report H3 dimensions per ratio

- web-search: the client base URL allowlist also accepts the exact base URL
  a built-in token plan preset writes for that provider, derived from
  TOKEN_PLAN_PRESETS. Applying a plan whose web-search route is not an
  official vendor host previously stored a URL that the route rejected with
  400. Any other client URL is still rejected.
- minimax-video: report H3 v2 clip dimensions for 16:9, 9:16, 4:3 and 1:1
  instead of assuming landscape for every non-portrait ratio.
- tests: pin the allowlist for every preset, the 1:1 H3 dimensions, and
  clear TOKENDANCE_* in the provider-config env isolation list.

85ef52d599 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.

* 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.

* 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.

* 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.

* 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.

* 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.

* 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.

* 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.

* 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.

* 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.

* 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.

* chore(storage): release 0.29.1

The asset HTTP handler now recognises a store refusal by the contract code it
declares as well as by its class, so a quota refusal raised in another module
realm answers 507 instead of 500. Same contract, stricter recognition, no API
change: a patch.

* 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.

* 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.

* 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.

* 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.

* 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.

* 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.

Tools address stages explicitly on every call, so the store keeps no

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.

* 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.

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

The reconciliation test iterates every tool the runner registers and

(list_voices, set_roster, clip_audio, register_voice) reached the
integration base with the roster/voice-registration tools but never
gained presentation rows, so they fell through to the default branch
and rendered their wire names. Port their rows from the reference
implementation (labels and i18n keys verbatim) and extend the
reconciliation allowlist with ROSTER_TOOL_NAMES and
VOICE_CLONE_TOOL_NAMES, so a future tool cannot enter the product

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

* feat: port workspace shell sibling modules

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Covers the three restored entry points:

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

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

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

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

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

Port the reference's LISTEN/NOTIFY delta path:

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

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

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

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

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

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

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

Bumps @openmaic/storage to 0.18.0.

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

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

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

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

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

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

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

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

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

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

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

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

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

Bump @openmaic/storage to 0.18.0.

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

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

* 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

* 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.

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

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

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

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

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

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

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

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

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

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

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

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

Standalone classrooms keep their stored mode unchanged.

Som SamantrayandCommandCodeBot 5dc023d92d feat(export): download narration script as Markdown or DOCX (#1144)
* feat(export): download narration script as Markdown or Word-compatible .doc

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

* refactor(export): simplify narration script export hook

Reads stage store state at click time instead of subscribing per render,
drops unobservable exporting state (the handler is synchronous and the
menu-close is the reentrancy guard), removes a redundant empty-scenes
pre-check, and drops a type cast the discriminated union makes
unnecessary.

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

* fix(export): apply code review findings for narration script

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

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

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

Addresses review from @wyuc on PR #1144.

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

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

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

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

* fix(review): apply review findings

* fix(export): remove legacy doc script export

Nguyễn Lê TrườngandClaude Opus 5 8db8785506 feat(i18n): add Vietnamese (vi-VN) locale (#1025)
Translate all 1,619 leaf keys with exact parity against en-US.json and
register the locale in supportedLocales.

Rebased onto current main (4ac70cce). Upstream drift resolved here:

- #1023 added 14 edit.agent.* / edit.roster.* keys and #995 added three
  export.video*Cta* keys; all are translated.
- #1060 retired the pbl.* v1 UI, so its 38 keys are dropped from vi-VN.json
  as well. check:i18n-keys compares both directions, so leaving them would
  fail on extras.
- #1068 (fr-FR) registered a locale in the same spot in locales.ts; both
  entries are kept.
- 120 keys landed since the last rebase and are translated in this pass:
  the canvas editor toolbars (edit.line.*, edit.insert.linePresets.*,
  edit.asset.*, edit.latex.*, edit.video.*, edit.audio.*, edit.image.*,
  edit.table.*, edit.contextMenu.*) and classroom folder management
  (classroom.folder*, classroom.deleteFolder*, classroom.moveTo*).
  Vietnamese has no plural inflection, so deleteFolderAndCourses and its
  _other form carry the same text; both keys are present because
  check:i18n-keys requires them.

Two extra files are required and could not be split out: LOCALE_RESOURCES
in lib/video-export-app/cover-config.ts and the expected-labels map in its
test are both typed Record<Locale, ...>. Without these entries tsc --noEmit
fails with TS2741 on '"vi-VN"', exactly as it did for fr-FR in #1068.
Seven added lines outside lib/i18n, no logic change.

Also translates the strings flagged in review that were still English:
the OpenAI/GLM/Qwen voice descriptions, browser-native TTS and ASR labels,
providerUnpdf, voiceNamePlaceholder, lang_auto, the VoxCPM voice-pool
labels, and the protocol/provider names. "(Local)" renders as "(Cục bộ)"
throughout. Left verbatim on purpose: settings.lang_* stay in their native
scripts (matching every existing locale), "Video" is the ordinary
Vietnamese word, and AccessKey ID / AccessKey Secret are the literal field
names in the Alibaba Cloud console.

README language counts updated to 11 and now include French, which #1068
had not backfilled.

pnpm run check:i18n-keys passes across all 11 locale files; prettier
reports the touched files clean; the i18n suite (39 tests) and the
video-export cover-config suite (92 tests) pass; tsc --noEmit reports no
error in any touched file.

PercyandPercy b8bba7653e feat(courses): add folder grouping (#1005)
* feat(courses): add folder grouping behind a feature flag

Group courses into user-created folders on the home page. Folders are
device-local organization metadata kept in the existing IndexedDB
database (new folders + course-to-folder mapping tables, Dexie v16);
the course document aggregate owned by the DocumentStore is untouched.

- Create / rename (inline) / delete folders (keep or remove members)
- Move a course between folders via a hover menu
- Navigate into a folder with a breadcrumb back to all courses
- Search flattens the list, annotating each course with its folder
- Deleting a course cleans up its folder membership
- All UI strings internationalized across 9 locales
- Gated behind NEXT_PUBLIC_ENABLE_COURSE_FOLDERS (default OFF)

* test(courses): update db mocks and version assertion for folder tables

The folder feature adds the `stageFolders` table to the deletion cascade
and bumps the Dexie schema to v16. Update the affected test db mocks to
include the new table and bump the version assertion accordingly.

* fix(courses): stop course click-through when selecting from the move menu

The move-to-folder menu is rendered inside the course card's clickable
container. Selecting a folder item could let the click event reach the
card's onClick (opening the course) because only the trigger button
stopped propagation. Stop propagation on pointerdown for the trigger
and on click for every menu item so selecting a destination never opens
the course.

* fix(courses): open a dialog for the move-menu new-folder entry

The move-to-folder menu's inline "new folder" input never worked: a Radix
DropdownMenu is modal, so a raw <input> inside it cannot keep focus —
Radix closes the menu the instant the input is focused, dropping the
field before anything can be typed. Move the new-folder entry out of the
menu: it now asks the caller to open the existing NewFolderDialog and,
on confirm, moves the requesting course into the freshly created folder.

* feat(courses): drag-to-file folders and stacked cover thumbnails

Per review feedback, make folders feel complete:

- Drag a course card onto a folder tile to file it there. The tile turns
  into a clear drop target (ring + overlay) while a drag is over it. The
  hover 📂 menu remains as the accessible fallback for keyboard/touch.
- Replace the placeholder folder icon with a stable stack of up to three
  member course covers (most recently updated frontmost). Empty folders
  keep the folder icon; the name and course count are always visible.

* feat(courses): refine folder cover stack to a tidy fanned layout

Tune the folder-tile cover stack per review: front cover centered and
upright, rear covers peek out from alternating sides with a slight tilt
and reduced opacity, soft shadow and hairline ring. Reads as a neat pile
of course covers rather than an exaggerated fan.

* fix(courses): address review — dialog mount, empty-list, rename validation, partial-delete refresh, breadcrumb dedup

Per review (wyuc, CHANGES_REQUESTED):

1. Mount NewFolderDialog/DeleteFolderDialog outside the collapsible Recent
   subtree so they are reachable while it is collapsed; the New-folder
   button now expands the section before opening the dialog.
2. Keep the Recent/folder surface alive when the course list is empty so
   folders remain reachable and a first folder can be created.
3. Enforce folder-name validation (width + uniqueness) on rename as well
   as create, at the storage boundary (FolderNameError) and in the UI.
4. Refresh authoritative state on folder-delete both success and failure,
   so a partial "remove" failure does not leave stale cards/counts.
5. Drop the duplicated folder breadcrumb from the top section header;
   keep a single navigation breadcrumb in the content area.

Add focused storage tests covering rename validation, membership writes,
both deletion modes, and partial-failure propagation.

* fix(courses): address 2nd review — folder-view layout, drop highlight, validation parity, a11y, i18n

Per review (wyuc, CHANGES_REQUESTED on 9f77686f):

P1 — folder view layout: opening a folder compacts the hero and surfaces
the library content; the centered header shows a single path
"Recent > Folder name"; the empty-folder state sits directly below it;
clicking Recent returns to the root grid. The duplicate content
breadcrumb is dropped (kept only for search).

P2 — correctness & a11y:
- Clear the folder drop highlight on every drag exit (dragenter counter)
  and gate it on the text/stage-id payload.
- Duplicate-name check in the dialog is now case-insensitive, matching
  the storage boundary; FolderNameError is mapped to specific messages.
- Renames report the actual submitted width, not a hardcoded 0.
- createFolder/renameFolder run read-check-write in one read-write
  transaction so the uniqueness invariant cannot race across tabs.
- The move-menu trigger is focus-visible and pointer-coarse reachable
  (visible on touch / keyboard), not hover-only.

Extra:
- Empty library (no courses, no folders) shows a dedicated hint instead
  of the search-empty string.
- Translate all newly added folder strings across ja/ko/pt/ru/ar, fix
  Simplified-Chinese text in zh-TW, and add the emptyLibraryHint key.

* fix(courses): address 3rd review — ungate folders, fix empty-library hero, stabilize the bar

Per review (wyuc, CHANGES_REQUESTED on 19729038):

P1 — ship folders unconditionally: remove NEXT_PUBLIC_ENABLE_COURSE_FOLDERS,
the isCourseFoldersEnabled helper, the .env.example entry, and every
flag-on/flag-off UI branch. Folder metadata is always loaded; create,
move, drag, and folder navigation are always available. The IndexedDB
v16 schema stays intact.

P1 — full-screen landing hero only when the library is truly empty: the
hero uses min-h-[calc(100dvh-8rem)] only when there are zero courses AND
zero folders. A `hydrated` flag waits for both async loads before
selecting the layout, so folders arriving from storage do not flip the
hero from full-screen to compact.

P2 — geometrically stable centered bar: the Recent bar gets a fixed
height (h-9) so entering/leaving a folder (which toggles the New-folder
action and the folder path) does not shift the search/import controls.

* fix(courses): single stable library action bar across root, folder, and empty states

Per review (wyuc, CHANGES_REQUESTED on 860a1170):

P2 — remove the duplicate floating import controls. The hero section
rendered a second Import Classroom / PPTX cluster whenever the course
list was empty, duplicating the Recent bar's actions and floating above
it as the hero switched layout modes. Import now lives only in the
Recent action bar.

P1 — keep folder creation reachable for a truly empty library. The
Recent section is now always rendered after hydration (not gated on
having courses or folders), so a new user with zero of each can still
create the first folder or import. The empty-library hint renders below
the single stable action bar.

Invariant: one library action bar across root, folder, and empty
states; state changes alter the path and enabled actions only.

* chore: trigger CI after ready-for-review

* fix(courses): inherit folder context when importing from inside a folder

Per review (wyuc, CHANGES_REQUESTED on 37be4716):

[P1] Courses imported from inside a folder were silently placed at the
root. The import contract now carries the new stageId to the success
callback; the page captures the active folder when the file picker opens
(not when the async import resolves) and files the imported course into
that folder before the list refresh, so the card appears immediately and
the folder count increments. Root imports remain ungrouped. A failed
folder assignment surfaces an explicit error toast instead of silently
falling back.

* fix(courses): stable hero on folder delete, lightweight delete menu, breadcrumb count, empty-name validation

Per review (wyuc, CHANGES_REQUESTED on 5e12984f) + QA findings:

P1 — deleting the last folder must not expand the hero. The full-screen
landing hero is a first-visit treatment only: a session-scoped
"librarySeen" flag latches true once the library bar renders, so the
hero stays compact across all subsequent create/delete transitions.

P2 — replace the heavy two-card delete dialog with progressive disclosure.
Empty folder: an inline confirmation overlay on the card tile (matching
the course-delete pattern), with the empty-folder copy. Non-empty
folder: a compact dropdown beside the delete icon — "Delete folder only"
(courses move to unfiled) executes directly; "Delete folder and N
courses" opens a lightweight destructive confirmation. The full modal is
gone.

QA fixes:
- Breadcrumb count is now contextual (total at root, in-folder count
  inside a folder) instead of always showing the global total.
- Renaming a folder to empty/whitespace shows a "name cannot be empty"
  error and shakes, instead of silently exiting edit mode.

* fix(courses): cross-review cleanup — dead i18n keys, missing translations, delete-overlay reset

Post-commit cross-review (leak audit PASS, wyuc 19/19 PASS) found:

- Remove 6 dead i18n keys left over from the removed two-card delete
  dialog (deleteFolderDesc, deleteFolderUngroupTitle, etc.) across all
  9 locales.
- Translate all remaining English folder strings in ja/ko/pt/ru/ar
  (newFolderTitle, folderNameLabel, folderCreate, deleteFolderTitle,
  etc.).
- Fix zh-TW: convert ~17 simplified-Chinese folder strings to
  Traditional (新增資料夾/建立/刪除/etc.).
- Delete the orphaned "feature flag" comment (flag was removed earlier).
- Close the inline delete-confirm overlay before the async delete, so a
  failure leaves the card interactive instead of stuck behind the
  backdrop.

* fix(courses): clear drop highlight on drag end, map limit error in dialog

Two minor findings from cross-review:

- Escape-cancelled drags may not fire dragleave on every folder target,
  leaving a highlight ring. The course card now dispatches a
  'course-drag-end' window event on dragEnd (fires for both normal drop
  and Escape cancel); folder cards listen and clear their drop state.
- FolderNameError kind 'limit' (thrown at the storage boundary when
  FOLDER_COUNT_LIMIT is reached in a cross-tab race) now maps to the
  specific folderCountLimit message in the dialog instead of falling
  through to a generic hint.

Also fixes an SSR hydration mismatch: librarySeen is now initialized
to false and read from sessionStorage in useEffect (not in the
useState initializer).

* fix(courses): atomic folder removal, always-compact hero, no-cover placeholder

Per review (wyuc, CHANGES_REQUESTED on 470f5fea):

P2 — close the orphan-membership race in 'remove' mode. deleteFolder now
captures members, deletes the folder row, and clears all memberships in
ONE transaction BEFORE the course-deletion cascade. The folder is gone
from the moment the cascade starts, so a concurrent setStageFolder
(which checks existence in its own transaction) rejects the assignment.

P2 — remove the first-visit full-screen hero. The librarySeen flag
caused a visible layout jump on refresh (SSR renders full-screen, then
the effect reads sessionStorage and switches to compact). The hero is
now always compact (mt-[10vh]); no sessionStorage, no hydration
mismatch, no geometry regression.

P3 — distinct no-cover fallback for non-empty folders. A folder with
courses but no cached thumbnails now shows a neutral stacked-card
placeholder instead of the empty-folder icon.

Merged with latest main; no conflicts.

* feat: add Claude as a web-search provider on the multi-provider framework

Forward-port of the original Claude web-search work onto main's
searchWeb dispatcher, per review guidance on #393:

- lib/web-search/claude.ts: searchWithClaude via the AI SDK Anthropic
  provider and Anthropic's native web_search server tool, called through
  callLLM for usage accounting. Returns the model's answer plus cited
  sources deduplicated by URL. The page-content enrichment fetch from the
  original PR is removed entirely, resolving the P1 SSRF finding (no
  server-side fetches of attacker-influenced result URLs remain).
- allowed_callers: ["direct"] is still injected at the fetch layer; the
  AI SDK's provider-defined web_search tools do not emit it.
- Tool version picked from the model: web_search_20260209 for 4.6+
  Opus/Sonnet, basic web_search_20250305 for Haiku/older; maxResults maps
  to the tool's max_uses.
- Registry/dispatcher/route wiring: claude provider entry, claudeModelId
  passthrough (web-search route, classroom generation, generation
  preview), WEB_SEARCH_CLAUDE_* env config with server-pinned model via
  WEB_SEARCH_CLAUDE_MODELS, and client base-URL allowlisting for
  api.anthropic.com.
- Settings: per-provider modelId with a model selector in the Claude
  panel; locale keys added to all ten languages.
- Tests: new adapter suite plus claude cases in the dispatcher,
  constants, route, provider-config, web-search-config, and settings
  store suites.

Closes #392

* fix(web-search): trim whitespace around the Claude API key and base URL

Keys are pasted by hand into Settings, and nothing in the client key
path trimmed them: a trailing newline or space was sent verbatim as the
x-api-key header value and came back from Anthropic as 'invalid
x-api-key', with nothing in the message pointing at whitespace.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

* fix(web-search): correct Claude adapter tool selection, base URL, and timing

Addresses the four P2 review findings on #393:

- Route dated Claude 4.0 ids (claude-sonnet-4-20250514,
  claude-opus-4-20250514) to the basic web_search_20250305 tool. The
  blocklist regex missed them, so they were sent web_search_20260209,
  which pre-4.6 models reject. Replaced with an allowlist of the models
  that have dynamic filtering, so unrecognized ids also fall back to the
  basic tool -- the safe direction, since 4.6+ models accept both.

- Pin allowed_callers: ["direct"] only on web_search_20250305. Injecting
  it into every request disabled the code-execution caller that provides
  dynamic filtering on web_search_20260209.

- Normalize the bare Anthropic root to /v1 before handing the base URL to
  the SDK, which appends /messages verbatim and would otherwise 404. The
  adapter is the single choke point for the client allowlist, the server
  env var, YAML, and the default; other hosts pass through untouched.

- Return responseTime in seconds, matching every sibling adapter's
  WebSearchResult contract instead of exposing milliseconds for Claude.

wyuc 0ae21aa559 refactor(pbl): retire v1 write path and dead UI, converge on v2 (#1060)
* refactor(pbl): retire v1 write path and dead UI (#1058)

Remove the legacy generator, renderer branches, chat API, and compatibility mirror writes.

Keep stored v1 scenes readable through documented legacy adapters, and surface ordinary PBL planner double failures instead of degrading.

* fix(pbl): contain planner failure to the scene, support legacy scenes in action regeneration, tighten legacy guards

- Contain typed planner failures per scene while preserving retry and skip behavior.
- Upgrade legacy PBL content before regenerating scene actions.
- Apply video-export import boundaries to legacy readers.
- Harden legacy rendering and empty-state handling.
- Restore legacy upgrade compatibility coverage.
- Remove retired translations and refresh fallback narration and legacy cover documentation.

* fix(pbl): keep tolerant legacy configs renderable, guard invalid chat timestamps

* chore(dsl): bump to 0.6.3 for README accuracy fix

The README no longer references the deleted PBLProjectConfig symbol; the version gate requires a bump for any publishable package input change.

* fix(pbl): harden legacy upgrade and persistence contract

* fix(pbl): align action prompt with v2 workflow and validate project containers

* fix(i18n): remove retired PBL v1 keys from the new fr-FR locale

The fr-FR locale landed on main after this branch removed the v1 UI key families; prune the same 38 keys so all 10 locales align with en-US.

* fix(generation): sync packaged pbl-actions template with the v2 wording

The generation package that landed on main carries a byte-identical copy of the app's pbl-actions template; sync the v2 rewording and bump the package version.

* fix(pbl): normalize legacy content and preserve planner status

* fix(pbl): propagate provider status and ground action prompts

* fix(pbl): classify planner failures for retry, default the project summary prompt input

* fix(pbl): fall back to legacy data when v2 payloads are damaged, harden summary building

* refactor(pbl): resolve hybrid content through a validity-aware resolver

* fix(pbl): keep one v2 acceptance criterion across validator, resolver and persistence

Persistence gates on the same container predicate as the validator and the renderer's resolver: payloads the renderer will not treat as v2 are inert bytes everywhere, avoiding runtime side effects for documents the write barrier would reject. An explicit null proficiencyAssessment stays processable.

* fix(pbl): require runnable projects and harden legacy fallback

* test(pbl): exercise the real save reload and hydration chain

* fix(pbl): require an instructor and usable microtasks before v2 takes precedence

* fix(pbl): fall back to the loop planner unless the provider failed or the user cancelled

* fix(pbl): require role and task identities before v2 takes precedence

Runtime normalization can repair status and create the instructor thread, but it cannot synthesize the role id that binds the thread, the microtask ids used by lookup and update paths, or the labels the workspace renders. The runnable predicate and its video-export mirror now require them, so identity-less payloads fall back to usable legacy data.

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.

* 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.

9d2689439e feat(i18n): add French (fr-FR) locale (#1068)
Translate all 1,533 leaf keys with exact parity against en-US.json and
register the locale in supportedLocales.

Two extra files are required and could not be split out: LOCALE_RESOURCES
in lib/video-export-app/cover-config.ts and the expected-labels map in its
test are both typed Record<Locale, ...>. That file landed on 2026-08-04
via #995, nine days after #942 (es-MX) merged, so no previous locale PR
had to touch it. Without these two edits tsc --noEmit fails with TS2741.
Seven added lines outside lib/i18n, no logic change.

Conventions: formal register (vous); French typography (typographic
apostrophes, ellipsis, U+00A0 before : ; ! ? % and inside guillemets);
all {{var}} and {var} markers preserved verbatim; settings.lang_* left in
their native scripts, matching every existing locale.

* Enable AWS-hosted text models without exposing ambient credentials

Rebase the Bedrock provider onto current main and close the review-requested security, credential lifecycle, usage attribution, configuration, and metadata gaps.

Constraint: Bedrock may use ambient AWS credentials only when explicitly enabled by the server operator
Rejected: Trust client-supplied provider types | permits built-in keyless IDs to reach Bedrock credentials
Confidence: high
Scope-risk: moderate
Directive: Keep provider ID/type validation at both request resolution and model construction boundaries
Tested: targeted Bedrock/resolver/config/usage tests; TypeScript; ESLint; i18n alignment; production build
Not-tested: Full suite has 27 failures in unchanged quiz/runtime and runtime/chat-storage tests

* Give Bedrock a recognizable provider identity

Use the official AWS architecture service icon so Bedrock no longer falls back to the generic provider cube in settings and model selection.

Constraint: Preserve the AWS-provided artwork without redesigning the service mark
Confidence: high
Scope-risk: narrow
Tested: SVG XML validation; provider unit test; TypeScript; ESLint; production build

f378c25a53 feat(storage): route settings/user-profile persist through KVStore (no legacy migration) (#1001)
* feat(storage): route zustand persist through KVStore

The settings and user-profile stores persisted through zustand's default
`localStorage` storage, while the rest of the app's small keyed values had
already moved to `@openmaic/storage`'s `KVStore` — two unrelated mechanisms
over the same browser API, which is the split-brain the storage RFC set out
to remove. `kvPersistStorage` shipped with the package but had no importer.

Add `lib/store/kv-persist.ts`, the app seam that adapts a `KVStore` into a
zustand `PersistStorage`, and wire both stores to it under an explicit
`account` scope. Store logic is unchanged: `version` / `migrate` / `merge`
still belong to the stores, only the bytes' destination moves.

Existing installs are adopted rather than orphaned. On first read the seam
moves the raw `localStorage` entry into the KV scope — write first, then
drop the raw key, so an interrupted migration leaves the value readable
from one side or the other but never from neither. Once KV holds the entry
it is authoritative, so a stale raw entry reappearing cannot roll back
newer state, and re-running can neither duplicate nor resurrect anything.
An entry that is not a readable persist envelope is left exactly where it
is.

Hydration is now asynchronous, because a `KVStore` may be remote. The
browser backend resolves within a few microtasks of the store module being
evaluated, so nothing user-visible changes, but tests that assert on
persisted state now await `persist.rehydrate()` instead of relying on a
synchronous read.

The four pre-persist keys (`llmModel` / `providersConfig` / `ttsModel` /
`selectedAgentIds`) are deliberately untouched: they are read-only inputs
to a migration that never owned them, and `providersConfig` is still read
independently by `lib/ai/providers.ts`.

Part of #857.

* fix(storage): close the async-storage failure modes in the KV persist seam

Cross-review found that routing `persist` through an asynchronous store
opens failure modes a synchronous `localStorage` never had. Each one below
is now covered by a test that fails without its fix.

Data loss on a failed or empty hydration. A KV read that threw was
indistinguishable from an empty scope, so the store stayed on defaults
while an always-on initializer's `set()` persisted those defaults; the
next load then read them as a completed migration and deleted the raw
original, leaving nothing. Reads now separate "nothing there" from "the
backend could not answer": a failed read serves the raw entry read-only,
adopts nothing and deletes nothing, and leaves the key unwritable for the
session so no un-hydrated state can be persisted over an original. Raw
entries are additionally only dropped against a recorded completion
marker, so a KV entry of unknown provenance can never authorize deleting
the only copy of the user's data.

Lost adoption across tabs. A reader whose KV read answered before another
tab's adoption write, and whose localStorage read landed after that tab's
delete, saw nothing in either place and hydrated defaults. Against a
remote backend that interleaving is ordinary rather than rare, so an
apparent "nothing anywhere" is now re-checked before it is believed.

Out-of-order writes. Two rapid `setItem`s could complete in either order
and let the older value win. Reads and writes are serialized per key.

Pre-persist migration resurrecting on every load. `migrateFromOldStorage`
was guarded by the existence of the raw `settings-storage` key — the very
key the migration removes — so once the blob moved into the KVStore it ran
on every load and republished whatever the pre-persist keys still held,
including API keys the user had since deleted, into first-frame state. It
is now the persist layer's last-resort source instead of a synchronous
read in the store initializer: its result is adopted like any other
migration, so the adopted entry is the marker that stops it. Initial state
is plain defaults, and nothing stored reaches observable state before the
storage layer has vouched for it. The source keys are still only read,
never deleted, since `lib/ai/providers.ts` remains a reader.

Also: KV reads and writes are guarded so a corrupt entry surfaces instead
of throwing through zustand's silent catch; clearing the cache now clears
the migrated stores through their own storage, which a server-backed
scope would need and a blanket `localStorage.clear()` would only appear to
do; `removeItem` drops the KV copy before the raw one; and the e2e suite
gains post-migration steady-state coverage, which every existing spec
missed by seeding the pre-cutover key.

Part of #857.

* fix(storage): scope migration bookkeeping to the device, gate writes on call

Second review round. The findings shared one root cause: two of the three
sentinels recorded a fact about *this machine's* files but were stored
beside the data, in the store's own scope. Under a syncing `account`
backend that is a category error with teeth — one device's history would
travel to another and authorize deleting files it says nothing about.

Sentinels are now always `device`-scoped and carry a reserved `__` prefix,
whatever scope the store uses. The worst combination this closes: device A
migrates, its marker syncs, device B — which has never run this build —
loads and deletes the raw entry that is still the only copy of its own
settings. A test drives exactly that sequence against two devices sharing
one account scope and nothing else.

The pre-persist fallback gains a device sentinel of its own. Its source
keys are device-local and deliberately left in place, so "KV and raw are
both empty" was not a safe trigger: clearing the account entry, from the
cache button or a server-side wipe, let any device re-read those keys and
republish credentials the user had rotated. It is now consulted at most
once per device, and `removeItem` deliberately does not clear that
sentinel — clearing the entry is precisely the case it exists for. The
fallback also no longer writes the adoption marker: that marker is a
licence to delete a raw persist entry, and the fallback has adopted no
such thing. Were it written, a raw entry later restored by an older bundle
would be deleted unread.

The write gate is now read when `setItem` is called rather than when its
queued turn arrives. Evaluated inside the queue, a write issued during
hydration waited behind `getItem`, found the gate opened by the very read
it raced, and persisted its pre-hydration snapshot on top of the stored
value.

Refused writes are no longer a dead end: the first one asks the store to
rehydrate, since the backend may have recovered, and if that does not work
the user is told through a durable notice rather than losing every change
on reload. Each refusal is logged, not just the first — a once-per-session
warning hides how long a session has been silently unsaved.

`removeItem` now propagates backend failures, so clearing the cache cannot
report success for a clear that did not happen, and that flow reloads
immediately instead of leaving a window in which a background `set()`
re-persists the credentials just deleted.

Also: the recovery hook is bound after each store is constructed, because
naming the store inside its own definition made its type circular and
silently widened every selector to `any`; the `serial` comment no longer
claims an unreachable rejection handler; and the pre-persist version stamp
documents that it skips `migrate`'s unversioned normalization too, which
`merge` redoes anyway.

Part of #857.

* refactor(storage): make the KV persist seam a per-key state machine

Three review rounds kept turning up the same defect class in new places:
a backend failure read as "there is nothing there", and the result of an
operation that nobody looked at. Patching instances of it was not working,
because both are possible whenever a call site is free to decide for itself
what a failed operation meant. This makes that decision unavailable to
call sites.

Every backend call now returns an `Outcome` whose payload is a private
field and whose only reader demands a `KeyState`. Feeding the machine is
not a convention to remember; it is the only way to get the value out.
What comes back is the value or `UNAVAILABLE` — deliberately not `null`,
so "the backend could not answer" is not spellable as "nothing is there".
The machine then decides, in one place, what failure means: any read
failure is unavailability, any write failure closes the key, and either
raises the health signal and asks for recovery.

The scattered closure flags (a settled set, a warned set, a recovery
latch) become one explicit phase per key — unhydrated, settled,
unavailable, clearing — with the transition table written out in the
docstring and a test per row.

What that consumes:

- A write failing after the key settled used to be ignored; its outcome
  now closes the key, signals, and the value is remembered for replay.
- `removeItem` enters `clearing` synchronously at call time, so a `set()`
  racing a clear cannot be admitted, queue behind the delete, and write
  the just-deleted value back. Nothing is replayed across a clear.
- The pre-persist sentinel is recorded by *every* settling path, not only
  the one that consults the old keys. A device that had only ever loaded
  an already-populated account entry recorded nothing, and so stayed
  eligible to republish its own stale credentials the moment that entry
  was cleared — which the docstring already claimed it would not.
- Two places treated a failed read as an answer: the sentinel read that
  decides whether the fallback runs, and the confirming re-read before
  adopting. Both now stop.
- An adoption whose marker did not land no longer settles, and never
  deletes the raw entry: no proof, no licence.
- Refused and failed writes are remembered and replayed once storage
  recovers, but only when the store was holding real data at the time —
  replaying a snapshot taken over defaults would overwrite the stored
  value, which is the failure this seam exists to prevent. When a
  snapshot cannot be replayed the user is told, because rehydration is
  about to discard those edits.
- Health notices publish on a later task, so a recovery that lands
  moments later cancels a warning nobody should have seen, and a
  subscriber mounting after the failure is caught up once its toast host
  exists. `StorageHealthNotice` now sits after the `Toaster` for the same
  reason.

Also: adoption re-reads before committing so a concurrent write is not
rolled back; a shadowed raw entry is only deleted if it parses, matching
the promise never to delete bytes we could not read; the unavailable copy
points at the control that resolves it rather than suggesting a reload
that cannot; and the version pin, the pre-persist retention rationale, and
the cache-clear comment say what is actually true.

Part of #857.

* fix(storage): separate the contexts settle() was conflating

Convergence round on the state machine. The findings share a root: settle()
treated every read that concluded as licence to open the key, without
asking what else was true at the time.

- A read finishing while a clear is outstanding no longer settles. Under a
  remote backend a recovery rehydrate in flight during a clear is ordinary,
  and opening the gate there admits a write that queues behind the pending
  delete and restores the credentials just removed. Only finishClear opens
  a cleared key.
- The raw entry served read-only after a failed read no longer counts as
  the authoritative value. A shadowed raw entry is by construction the
  older copy — long-term coexistence with a newer KV value is a designed
  state — so an edit taken against it must never be replayed, or one
  transient read failure on one device rolls the whole account back.
- A write that lands supersedes an earlier failed one. Both were admitted
  before the key closed, so the queue ordered them; replaying the older
  snapshot on recovery would undo the newer value.
- Unreachable browser storage is a failure, not an empty store. Privacy
  modes make localStorage throw; treating that as "nothing stored" hydrated
  defaults, refused every write and said nothing until the user reloaded
  and found the work gone. SSR stays a silent no-op.
- The recovery latch re-arms when storage answers, so the three recovery
  transitions are not empty promises from the second failure onward.
- A refusal carries the phase it happened in. Cold-start timing — an
  always-on initializer writing before the first read resolves, on a
  backend that never failed — is a log line, not a sticky red toast; only
  a refusal under `unavailable` reports lost changes.

The health channel stops delivering stale catch-ups: its timers are
cancellable and re-read the current state when they fire, so a recovery
cannot be overtaken by a warning with nothing left to dismiss it. And
`changes-lost` is now a fait accompli rather than a condition — a later
recovery has nothing to retract and leaves it standing.

Also: a throwing `localStorage` is unavailability rather than absence
wherever the raw entry is read; clearing records the pre-persist sentinel
like every other settling path, making that docstring true; the raw entry
is dropped before the marker so a failed marker clear leaves something
inert; and the pre-persist fallback and its four source reads can no
longer throw into zustand's silent catch.

Part of #857.

* fix(storage): hold a replay until it lands, and prove a raw copy before deleting it

Three failure-path corners.

A replay was retired the moment its write was attempted. Readable but not
writable is a real state — a quota-exhausted backend answers reads
perfectly — so a recovering read could succeed, the replay write fail, and
the snapshot be gone with nothing owed: the next rehydrate served the older
stored value over the user's edit and said nothing. The snapshot is now
held until the write is durable; a failed replay goes back to being a
refused write, so the next recovery tries again and a permanent failure is
eventually reported.

The adoption marker was treated as proof that a raw entry is the
migration's leftover. It proves only that a migration happened on this
device once. A rolled-back deployment, or a tab still running the old
bundle, writes the raw key again with settings the migration never saw, and
the next load on the new bundle deleted them unread. A raw entry is now
dropped only when its content equals the value shadowing it — anything else
is data, and keeping a copy beats deleting an original here as everywhere
else in this file.

`changes-lost` was being cancelled by a later recovery. The two statuses
answer different questions: "storage is down" describes the world now and
stops being true when storage works, while "your edits were lost" describes
something that already happened and no amount of recovery undoes. They are
now tracked on independent lines per key and rendered as two toasts with
distinct ids, so retracting the fault cannot take the acknowledgement with
it; the loss notice goes away only when the user closes it.

Part of #857.

* fix(storage): bound recovery, keep a live store from walking backwards

Three interactions the state machine did not have an answer for.

Recovery had no budget. A backend that reads but cannot write — a
quota-exhausted one does exactly that — turned it into a treadmill: the
recovering read succeeds, the key settles, the replay write fails, and that
failure asks for recovery again, forever. Attempts now follow a backoff
schedule whose length is the cap, and the budget is re-armed only on real
progress: a settle that left nothing owed. A settle reached *by* a recovery
with a replay still queued is not progress, and counting it as such is
precisely what made every lap look like a fresh start. When the budget runs
out the key is left read-only and the loss is reported, rather than
retrying where nobody can see it failing.

A failed read could walk a live store backwards. Once a session has loaded
the authoritative value, a transient read failure was still falling back to
the shadowed raw copy — which is legitimately older, and legitimately
long-lived now that a differing raw entry is kept rather than deleted — and
handing it to zustand overwrote a live store with stale data. Worse, the
store had already latched "holding real data", so edits made on top of that
stale value counted as replayable. A failed read after an authoritative one
now returns nothing, which is exactly "keep what you have", and the raw
fallback stays where it belongs: the case where nothing authoritative has
been seen at all.

Dismissing a lost-changes toast only closed the UI. The key stayed in the
lost set, so the same store losing changes a second time was swallowed as a
duplicate and any later subscriber resurrected a notice the user had
already dealt with. The close button now clears the latch, so a second loss
is reported and an acknowledged one stays gone.

Part of #857.

* fix(storage): close the last two provisional and clear-ordering gaps

An abandoned migration was handing back an authoritative value. When the
confirming re-read fails, or the adoption write does, `adopt` returns the
raw envelope unadopted — the same footing as the raw copy served after any
other failed read — but it was returned bare, so the store latched "holding
real data" and an edit taken on top of it counted as replayable. Another
device publishing to the account scope in that window would have been
rolled back. `adopt` now reports provisionality like every other read path,
and the shape is a named `LoadedValue` so the next path cannot forget.

Clearing swallowed a failed raw-entry deletion. The account entry was
already gone by then and the marker was cleared afterwards, so the
operation reported success while leaving an empty scope beside a live raw
entry — precisely the shape the next hydration re-adopts, handing back the
settings the user had just deleted. The raw entry now goes first and its
failure propagates, which also fixes the ordering: failing before anything
is removed leaves the KV value authoritative and the clear simply
unperformed, which the caller can retry. Adoption keeps the tolerant
variant, where a leftover raw entry is a duplicate rather than a loss.

Part of #857.

* fix(storage): make the shadowed-raw delete atomic against a concurrent tab

cosarah reproduced a data loss: both raw-entry deletes verified the value,
then awaited (reading or writing the adoption marker), then removed the key
by name. A tab running an old bundle — which takes no Web Lock, so a lock
could not have helped — overwrites the raw key with newer settings during
that await, and the unconditional `removeItem` then deletes the newer value.

The raw side is synchronous `localStorage`, so the fix needs no lock. Both
deletes now finish every await first, then run a single synchronous
compare-and-delete: re-read the raw bytes, and remove only if they still
equal the exact string that was verified. A competing tab is a separate
context whose writes surface here only at event-loop boundaries, so its
write lands wholly before the re-read (seen — bytes differ — kept) or after
the remove, never in between. A changed value is newer data, not a
migration leftover, and is kept.

Both sites cosarah named are covered: the shadowed-cleanup path
(`dropShadowedLegacy`) and the adoption cleanup in `adopt`. `readLegacyEntry`
now carries the exact bytes alongside the parse so the re-check is
byte-exact rather than comparing a re-serialized value. The clear path's
delete is unchanged: it is a deliberate full delete, not a conditional
leftover cleanup.

Part of #857.

* fix(storage): stop deleting the raw entry — adopt by copy (Plan B)

Maintainer decision after cross-vendor + red-team review: `localStorage`
has no cross-process atomic compare-and-delete (the storage mutex was
dropped from the spec), so a tab on an old bundle can insert a write
between our re-read and our removeItem in a genuinely parallel process. The
synchronous compare-and-delete narrowed that window but could not close it
— as its own comment admitted. Since the raw-cleanup cannot be done safely
on localStorage while an old bundle may be live, this stops doing it.

Adoption is now a copy: the value is written to KV and the raw entry is
left in place. The delete race is therefore impossible — there is no
delete. KV stays authoritative (once it holds the value, reads take the KV
path and never consume the raw one), so the shadow duplicate is inert,
left for a wholesale raw-cleanup at migration exit.

Removed with the two deletes:
- `dropShadowedLegacy` (its only job was the gated delete) and its three
  call sites.
- `deleteLegacyIfUnchanged` and the `{raw,value}` shape of the legacy read
  (`readLegacyEntry` → back to `readLegacy` returning the value).
- The adoption marker (`__persist-adopted:`), whose only reader was that
  delete gate. It did not prevent re-adoption — the presence of the KV
  value does — so removing it breaks no invariant. `dropRaw` / `expectedRaw`
  on `adopt` and the marker-clear step in the clear path go with it.

The clear path (user deletes all data) still deletes the raw entry
strictly — that is a deliberate full delete, not a migration cleanup.

Tests: the delete/marker cases become "the raw shadow always survives, KV
is authoritative"; a two-device and an old-bundle-concurrent-write case
guard it, and re-adding a delete on either adoption path turns them red.

Part of #857.

* fix(storage): add a monotonic migrated marker to stop shadow resurrection

Cross-vendor + red-team review independently caught a P1 the previous
"adopt-as-copy" revision introduced. Because the raw entry is now kept and
writes only ever reach KV, the raw copy becomes a frozen pre-cutover value.
If the account KV is later emptied by something other than a local clear —
a server-side wipe, an account switch, KV eviction — the next load saw
`stored === null` beside a live raw entry and re-adopted that stale copy,
refilling the wiped account with ancient settings/credentials and syncing
them to every device. Deterministic, not a race; it would fire once a
server-backed account backend exists.

Root cause: "keep the raw entry" inherently requires a record that it has
already been migrated, so an empty-KV load can tell "first migration" from
"external wipe". Removing the old delete-authorization marker in the copy
revision dropped that record — Plan B was only half done.

Adds a monotonic, device-scoped `__migrated:<name>` marker:
- Read on every load. `stored === null` + raw present + marker set ⇒ respect
  the wipe, do not adopt (fall through to the confirm re-read, so a
  concurrent repopulation is still served). Only a genuine first migration
  (no marker, raw present) adopts.
- Written best-effort after a successful KV write. A failed write degrades
  to the KV value's own presence check, so resurrection needs both a failed
  marker write and a later external wipe.
- Read failure fails closed (do not adopt), never "assume not migrated".
- Monotonic: only ever set true, cleared only by a deliberate full clear —
  no compare-and-delete race, which is why it is safe where deleting the raw
  entry was not. Live state with a real reader, not the delete-authorization
  marker removed earlier.

The clear path clears the marker too (back to a genuine first-load state);
best-effort, since with the raw entry already gone a leftover marker is
inert.

Tests: resurrection guard (external wipe does not re-adopt; concurrent
post-wipe write is served; first migration records the marker; marker read
fails closed) + the clear-path marker clearing. Mutation-checked: removing
the gate resurrects the shadow, dropping the record leaves it unguarded.
P3: the inert `__persist-adopted:` test rot is retargeted to the real
`__migrated:` path.

Part of #857.

* refactor(storage): remove automatic legacy migration — pure KV wiring

Maintainer decision (terminal): after repeated review rounds kept finding
new P1s in the legacy-adoption path — its state space is too large to keep
correct — the PR is narrowed from "migrate + wire" to "wire only". Settings
and user-profile persist through the KVStore; pre-cutover data is not
migrated; an upgrading user reconfigures once (the data is reconstructable
and the cost is one-time).

Removed the entire legacy-adoption subsystem from the adapter:
- `adopt()`, `readLegacy()`, the `legacyStorage` dep, and the raw-fallback
  read on a failed KV read.
- The `__migrated:` marker and its resurrection guard, the confirm-re-read,
  and the `provisional`/`LoadedValue` machinery.
- The `prePersistFallback` dep, `recordPrePersistHandled`, the
  `__pre-persist-consulted:` sentinel, and `readSentinel`/`writeSentinel`.
- In settings.ts, `readPrePersistSettings` (the llmModel/providersConfig
  reader wired as that fallback) — reading legacy keys is migration, which
  this PR no longer does. `lib/ai/providers.ts` still reads `providersConfig`
  independently, so those source keys are left in place.

The adapter now reads and writes the KV scope and touches no legacy key: an
empty scope hydrates the store to defaults (ordinary zustand). `load()` is a
single KV read; a failed read stays unsettled so defaults are never
persisted over an unread value; the clear path removes only the KV entry.

Kept, because they are async-storage *steady state* a remote KV backend
needs, not migration scaffolding: the KeyState machine (hydration gate,
write gate, recovery, replay), the Outcome discipline, per-key
serialization, and the persist-health channel.

Added `purgeLegacyPersistKey`: a best-effort, fire-and-forget removal of the
old raw persist blob, called once by each store. Never read, so a leftover
is pure garbage — and the old settings blob held plaintext provider API
keys, so clearing it is a small security win.

Net: the adapter drops ~460 lines. Tests are rewritten to steady-state KV
coverage plus an explicit "old raw key is ignored, not migrated" proof at
the store level; the e2e seed fixtures move from the raw key to the KV scope
key.

Part of #857.

* docs(storage): align README and comments with the no-migration behavior

Follow-up requested on the approved PR: the migration/adoption logic was
removed, but a few comments and one README roadmap line still referred to
those deleted concepts. Documentation only — no behaviour change.

- README roadmap: the settings/user-profile line said "adopting their
  pre-cutover raw keys"; it now states there is no automatic migration
  (legacy keys ignored and best-effort purged, users reconfigure once).
- kv-persist.ts: the per-key serial chain comment no longer claims to keep
  "adoption" from interleaving; it serializes a key's read/write/clear.
- settings.ts: `SETTINGS_PERSIST_VERSION` no longer documents a
  "pre-persist fallback" that no longer exists.
- Test/fixture headers that described seeding "the pre-cutover raw key" for
  "one-time adoption" now describe seeding the KV `account` scope, with no
  legacy-key migration.

* fix(video-export): bridge play_video element id → media ref

Generated-media records are keyed by the element's media ref (gen_vid_…),
but a play_video action targets the slide element by its .id. The app-side
compiler deps looked media/durations up by the raw element id, so every
generated video missed → present:false → no <video> emitted, no bytes
collected → the clip vanished from the export (only its static first frame,
baked into the base PNG, remained).

Build an elementId → mediaRef bridge across all slide scenes in
createVideoTimelineDeps (mirroring the live engine's resolveMediaPlaceholderId)
and resolve both media() and videoDurationMs() through it.

* fix(video-export): re-measure KaTeX fit-scale after fonts settle

KaTeX sizes large delimiters (\left\{, \begin{cases}) from its KaTeX_Size
faces, which load asynchronously. KatexContent measured its shrink-to-fit
scale once on mount, against the fallback font, and never recomputed — so a
cold slide snapshot baked a stale scale and the big brace desynced from the
piecewise body ("大括号后面的分段函数与大括号错位").

- Re-run the fit-scale measurement on document.fonts.ready and on each
  `loadingdone`, keeping the shrink-only (cap-at-1) behavior.
- slideToPng waits two extra frames before capture so the font-triggered
  React re-measure commits into the DOM html2canvas reads.

* fix(video-export): place spotlight/laser/video on the rendered content box

The pure geometry helper resolves an element's authored outer box against a
fixed 1000×562.5 base, but the live overlays — and the exported frame PNG —
measure the element's `.element-content` box, which for horizontal text is
auto-height plus 10px content padding. So a spotlight/laser sat offset from
where the text actually renders ("spotlight 与对应元素的位置有偏差", #867 item 5).

Add an optional GeometryProbe to the compiler's DI boundary: when supplied, the
geometry pass prefers each element's measured content-box geometry (video keeps
its rotation from the authored element), degrading to the pure authored-box calc
on a miss so the compiler stays deterministic in unit contexts.

App side: measureSlideElementGeometry (new, in @openmaic/renderer/snapshot)
mounts the slide off-screen and reads the same `.element-content`-against-
container box the live SpotlightOverlay uses; createVideoTimelineDeps
pre-measures every spotlight/laser/play_video target per scene and serves the
probe as a synchronous table lookup.

Tests: geometry.test.ts quantifies the outer-box vs content-box delta and proves
probe-wins / fallback / rotation-preservation; timeline-deps.test.ts covers the
pre-measure wiring.

* fix(video-export): decode a first-frame poster for posterless videos

A play_video clip only shows during its play window; the rest of the time the
static base-frame PNG backs that spot. But html2canvas can't draw a <video>, so
the snapshot swaps it for its poster <img> — and generated videos usually carry
no poster, leaving the video area blank whenever the clip isn't playing.

When a video record has no stored poster bytes, decode the video blob's first
frame (seek slightly off 0, draw to a canvas) and set element.poster before the
base snapshot, so that spot shows the first frame — the "paused on frame one"
look — instead of blank. Falls back to no poster on decode failure / timeout /
CORS taint, never failing the export.

* feat(video-export): split subtitles, make burn-in optional, centered modal

Burned-in captions used one cue per whole narration paragraph, so a long cue
became a 4–6 line block covering the lower half of the slide, and there was no
way to turn it off.

- Split cues (pure, compiler layer): lib/video-export/split-cue.ts splits each
  cue on sentence → clause → hard-wrap to ≤~40 CJK-equiv units, distributing the
  parent window by character weight (last piece pinned to the parent end, sub-1.2s
  slivers merged). Wired into the timeline pass, so the burned-in overlay and the
  SRT/VTT sidecar share one split track and can't drift.
- Burn-in optional (default off, #867 item 2): emitHyperframes gains
  burnInSubtitles; off → clean video + sidecar SRT/VTT only. Caption layout hard-
  clamped to 2 lines so an outlier can't grow tall again.
- Download subtitles without rendering: compileSubtitles() runs only the compiler
  (no assets/zip/service); new useDownloadSubtitles saves an .srt.
- Centered modal: video-export-dialog.tsx replaces the cramped dropdown section,
  grouping Output / Subtitles / Actions / Progress with a stable lifecycle for
  multi-minute renders. header-controls opens it from an "Export Video" entry;
  old video-export-menu.tsx removed. i18n keys added across all 8 locales.

playVideo helper (and its PlayVideoAction import) were dead. Flagged by the
code-quality bot on #952.

* fix(video-export): resolve cross-review findings + lower subtitle band

- emit-hyperframes: drop duplicate `display:-webkit-box` on subtitle cues so
  they start truly `display:none` (a second declaration overrode the `none`,
  showing every cue stacked at t=0 when burn-in was enabled).
- geometry: don't feed the measured content-box AABB to a rotated video clip —
  it already encloses the rotation, so re-applying `rotate` doubled it. Rotated
  elements fall back to the authored box (one, un-doubled source of truth).
- build-export-zip: extract shared `compileStageIr` so buildExportZip and
  compileSubtitles can't drift on the timing/assets/geometry wiring.
- split-cue: join merged CJK cue pieces without a spurious ASCII space.
- subtitles: lower the caption band (bottomRatio 0.055 → 0.01) and hoist the
  band's magic numbers into a named SUBTITLE constants block.

* fix(video-export): stop the snapshot onclone override from reshaping KaTeX

The export snapshot injects a neutral-kerning / geometricPrecision style over
`.slide-renderer-prose *` to keep CJK prose+table glyphs from mis-advancing
under html2canvas-pro. KaTeX formulas (output:'html') also live inside
`.slide-renderer-prose`, so the override was reshaping their math glyph
advances — a burned-in formula rendered subtly differently from the live
canvas, which applies no such override.

Empirical check (Playwright + system Chrome, cases+fraction formula, native
paint vs html2canvas): the override raised the formula's mean per-pixel delta
vs the live paint from 120.1 to 139.2 (~16%) and moved ~75% of inked pixels.
Restoring native font-kerning/text-rendering for `.katex` subtrees brings the
formula's delta back to 120.1 (bit-identical to the no-override capture) while
prose and table text keep the override. The residual 120.1 is the deeper
html2canvas rasterization gap (vlist/frac-line/delimiter), a separate track.

* fix(video-export): render slides via native paint, bundle KaTeX font embed

Root-fix the exported-vs-live formula distortion (and the filter/mask/video
gaps) by rasterizing slides with native Chrome paint instead of html2canvas's
reimplementation.

- slideToPng now captures via html-to-image (foreignObject → the same Chrome
  engine that paints the live classroom rasterizes the same DOM). KaTeX
  formulas, CSS filter, soft-edge masks, and mixed CJK/Latin text come out as
  the classroom shows them. html2canvas-pro stays as a fallback (with the
  filter/mask bakes + KaTeX text-rendering reset) for when native paint can't
  run — e.g. a cross-origin image taints the canvas.

- A foreignObject SVG can't reach the document font registry, so fonts must be
  inlined. KaTeX math faces are prepended from the bundled woff2
  (KATEX_FONT_EMBED_CSS, generated by scripts/generate-katex-fonts.mjs), NOT
  left to runtime getFontEmbedCSS — which reads cssRules and silently drops a
  cross-origin KaTeX stylesheet, collapsing a large brace to a fallback glyph
  (the observed "formula render failure" on e.g. a \begin{cases} with \text{}).
  A per-face guard verifies every KaTeX face the formula references is embedded,
  falling back to html2canvas otherwise.

Verified in a Playwright spike (native vs html2canvas vs html-to-image): formula
inked-delta 143→53; filter/mask/video match native; and with getFontEmbedCSS
forced empty, the bundled embed alone still renders the failing formula
correctly. Renderer package tests: 226 passed.

* fix(video-export): prettier-format the generated KaTeX font-embed module

The generator emitted an unformatted TS file (double quotes, long unwrapped CSS
literal) that failed CI `prettier --check`. Run the generated output through the
repo's Prettier config before writing, so every rebuild produces CI-clean,
stable output. Regenerated the committed file to match.

* fix(lint): rename reserved `module` var in katex-fonts generator; ignore .scratch

- generate-katex-fonts.mjs assigned to a variable named `module`, tripping
  @next/next/no-assign-module-variable (the one hard eslint error). Renamed to
  `fileContents`; generated output is byte-identical (deterministic).
- Add `.scratch/**` to the eslint globalIgnores (alongside .claude/.worktrees)
  so local throwaway verification scaffolding doesn't pollute `pnpm lint`.

* fix(video-export): address PR #952 review — scene-scoped media bridge, safer cue splitting

Resolves the two blocking correctness issues and three follow-ups from the
cross-review on #952.

- Scope the elementId→mediaRef bridge by scene (was deck-wide/last-writer-wins):
  slide-local ids like `video_001` now resolve within their own scene. `assets.media`
  uses its scene arg; `timing.videoDurationMs` resolves via action object identity.
  Adds a cross-scene collision test.
- Stop treating every ASCII period as a sentence boundary: a lone `.` splits only
  when not between word chars (3.14, v1.2) and not an abbreviation dot (e.g.),
  collapsing repeated-punctuation runs. Adds decimal/version/abbrev/ellipsis tests.
- Share the module-level in-flight guard across ZIP export and subtitle download
  (extracted to export-in-flight.ts); dialog `busy` folds in `downloading`.
- Skip the off-screen geometry render for the subtitles-only path (skipGeometry);
  duration probes are kept so sidecar cue timing stays in sync with the video.
- Align measure.ts font settling with slideToPng: force-load each used face before
  fonts.ready so measured content-boxes don't bake fallback advance widths.

* perf(video-export): enable beginFrame capture via PRODUCER_BROWSER_GPU_MODE=hardware

The producer defaults to `software` GPU mode, which silently force-enables the
CPU-bound `Page.captureScreenshot` fallback: SwiftShader pins every core on
rasterization and caps frame capture at ~10 fps. Selecting `hardware` keeps
Chromium's `HeadlessExperimental.beginFrame` capture active instead.

Measured on a 900-frame (30s) clip, no real GPU on the host:
- capture ~10 -> ~19 fps, total 100s -> 62s (~38% faster)
- CPU peak ~810% -> ~98%; peak mem 2.2 GiB -> 0.9 GiB
- static frames pixel-identical; animation frames differ only in sub-pixel
  edge antialiasing (same-path re-render is deterministic/inf PSNR)

No real GPU is required — the win is the faster capture API, not hardware
rasterization; beginFrame falls back gracefully if the host lacks a GPU. Also
eases the RENDER_JOB_DEADLINE_MS timeout risk on long videos.

* refactor(video-export): sentence splitting via Intl.Segmenter + abbreviation merge

Addresses the PR #952 follow-up: separate sentence-boundary detection from cue
shaping and stop growing a custom punctuation heuristic.

- splitSentences now delegates boundary detection to Intl.Segmenter (locale-
  agnostic ICU), the multilingual/CJK baseline. It already preserves 3.14, v1.2,
  e.g., U.S., ellipses, and CJK 。!?… without any hand-rolled period scan.
- ICU still ends a sentence after a titlecase abbreviation before a capitalized
  word (Dr. Smith, Fig. 3) — the edge case the reviewer flagged. A small
  abbreviation-aware post-merge re-joins those, driven by an ABBREVIATIONS set.
- Semicolons are no longer sentence ends (they join clauses); moved ;; into the
  clause-level SECONDARY splitter so over-budget sentences still break there.
- Cue shaping (budget / clause / hard-wrap / weighted timing) is unchanged, so
  detection and shaping are now distinct stages.

Not using `sbd` as suggested: lib/video-export/*.ts sits behind the machine-
enforced eslint purity boundary (imports limited to @openmaic/dsl, zod,
../choreography, siblings), so a new npm dep is rejected. Intl.Segmenter is a
pure Node >=20.9 builtin, matching the reviewer's "small abbreviation-aware
post-merge layer" alternative.

Tests: add Dr. Smith / Fig. 3 / U.S. coverage; the rhetorical ellipsis now stays
one under-budget cue (was split); add a semicolon over-budget case. 22/22 pass.

* i18n(es-MX): add 7 subtitle/video export keys to align with en-US

main added the Spanish (Mexico) locale (#942) after this branch's subtitle
keys landed, so es-MX was the only locale missing export.subtitles* and
export.videoBurnSubtitles* — which failed the i18n key-alignment CI check.

* fix(video-export): restrict title post-merge so it never deletes real boundaries

Addresses the blocking re-review on the Intl.Segmenter change: the abbreviation
post-merge unconditionally rejoined the next ICU segment whenever the previous
one ended in a listed abbreviation, which erased genuine sentence boundaries —
`It was made by Acme Inc. Next point.` collapsed into one cue, and even an
explicit newline (`Acme Inc.\nNext topic`) was rejoined.

The merge now fires only for the case ICU actually mis-splits — a title
(Mr/Mrs/Ms/Dr/Prof/Sr/Jr) before a capitalized proper noun — and only when:
  - the previous segment does not end at a newline (hard boundary), and
  - the next segment starts with a capital letter.

Sentence-trailing abbreviations (Inc./Ltd./etc./vs./No.) are dropped from the
set entirely: they legitimately end sentences, and ICU already keeps a title
before a number (No. 5, Fig. 3) or a lowercase continuation (etc. and…) whole
without any merge, so nothing there needs rejoining.

Regression tests: Inc./etc. boundary preserved, newline-after-title preserved,
lowercase continuation kept whole, plus the retained Dr. Smith / Fig. 3 / U.S.
cases. 26 split-cue tests pass; full video-export suite 123 pass.

davidmedel 1466a55eef feat(i18n): add Spanish (Mexico) locale (#942)
Spanish is not among the supported locales, so browsers sending es/es-MX
fall through resolveLocale to the default (zh-CN) and Spanish-speaking
users get the UI in Chinese.

- lib/i18n/locales/es-MX.json: complete translation (1,504 keys), following
  TRANSLATION_GUIDE.md including the design-intent notes (greetingWithName
  as CTA, defaultNickname warm and gender-neutral, readyToLearn inviting).
- lib/i18n/locales.ts: register es-MX at the end of supportedLocales per the
  guide, making it the default for the bare 'es' prefix.

Rebased onto current main and translated the 17 keys added since the branch
diverged (15 export.video* + chat.softClosing + roundtable.softClosing), per
@wyuc's review. Key parity and {{interpolation}} variables verified with
scripts/check-i18n-keys.mjs (passed: 9 locale files aligned).

* 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.

* 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.

* 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.

* 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.

* 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.

* 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.

* 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.

Surface each element's id (and code line ids) in the Pi whiteboard context so
later child agents can target wb_delete / wb_edit_code, and cap the rendered
code lines with a shared character budget so a code-heavy board cannot grow the
prompt without bound. Return only the current turn's whiteboard ledger from the
Pi director loop instead of carrying history forward across requests.

珀西andPercy 4c92111160 fix(export): resource pack unresponsive for interactive-only decks (#933)
A deck with only interactive scenes (no slide scenes) was silently
no-op when clicking Export Resource Pack: withExportGuard rejected
all export actions on slides.length === 0 with no toast or log, even
though the resource pack's own semantics (PPTX + interactive pages)
should still ship the interactive pages alone.

Changes:
- withExportGuard gains a requireSlides flag (default true). When it
  rejects it now toasts instead of returning silently.
- exportResourcePack passes requireSlides=false; the PPTX builder now
  runs only when slide scenes exist, with a toast when skipped.
- Assembly logic extracted into buildResourcePackZip (pure async fn)
  so it is unit-testable without a React harness.
- Regression tests cover: interactive-only deck ships a ZIP with the
  HTML page and no PPTX, and never calls the PPTX builder.
- New i18n keys (noSlides / noSlidesSkipped / nothingToExport) across
  all 8 locales.

d8a0081c7d feat(video-export): L1 Hyperframes emitter + browser collection + export ZIP (#865) (#931)
* feat(video-export): L1 Hyperframes emitter + browser collection + export ZIP (#865)

Consume the VideoTimeline IR (#864/#913) and produce a self-contained
Hyperframes composition project that `npx hyperframes render` turns into an
MP4 (render execution itself is #866).

- lib/video-export/emit-hyperframes: pure IR → Hyperframes project emitter
  (one flat composition, one paused GSAP timeline on window.__timelines,
  spotlight/laser overlays from lib/choreography descriptors). Stays under
  the purity boundary; emits HTML/JS strings only.
- lib/video-export/subtitles: SRT/VTT serialization of the IR subtitle track.
- lib/video-export-app: impure app glue (DI adapters over Dexie, slide-snapshot
  collection lifted from #849, streaming ZIP packaging, useExportVideo hook).
- Vendor GSAP locally (public/vendor/gsap.min.js) — determinism red-line.
- Export menu entry with resolution select + i18n across all 8 locales.

Verified end-to-end against the real hyperframes CLI: lint passes 0 errors on
a real classroom export, and a rendered slice produces a valid H.264+AAC MP4.

* feat(video-export): gate Export Video menu behind NEXT_PUBLIC_ENABLE_VIDEO_EXPORT flag

The video export UI is experimental until the render pipeline (#866) lands, so
hide the "Export Video" affordance behind an off-by-default feature flag.

- Add isVideoExportEnabled() to lib/config/feature-flags (NEXT_PUBLIC_, so it
  inlines at build time for the client-side export menu).
- Gate the Export Video block in header-controls on the flag.
- Cover the new flag in tests/config/feature-flags.test.ts.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* fix(video-export): ossKey fallback for evicted blobs + emitter dedup

Address code-review findings on #931.

- collect: resolveBytes() prefers the local Dexie blob and falls back to
  the record's CDN ossKey (audio) / ossKey+posterOssKey (media/poster) so a
  live-mode classroom whose local blobs were LRU-evicted still exports a
  self-contained ZIP. timeline-deps presence checks widened to
  `blob.size > 0 || !!ossKey` so the compiler keeps these entries instead of
  marking them absent; video-duration probe stays local-only.
- emit-hyperframes: extract one shared escapeHtml + sec into format.ts,
  dropping the two divergent escapers (attr vs escapeHtml) and the two sec()
  definitions with different rounding, plus the middle-man escapeAttr. Output
  is byte-identical (snapshot unchanged).
- Add tests/video-export/collect.test.ts (ossKey fallback, local-first,
  fetch 404/throw, video+poster).

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* fix(video-export): restore evicted generated media into base-frame snapshots

Address review blocker (P1) on #931: the ossKey fallback covered standalone
audio/video/image/poster asset entries but not the slide base-frame path.
resolveGeneratedMedia only accepted a non-empty local blob, so a live-mode
record with an evicted blob + valid ossKey had its image src cleared (and
video/poster not restored) before slideToPng snapshotted the slide — the frame
PNG lost the generated media even though the standalone asset was fetched.

- resolveGeneratedMedia now resolves bytes via resolveBytes (local blob first,
  then ossKey / posterOssKey) before creating the snapshot object URLs.
- Add frame-collection tests: evicted image restored via ossKey, evicted
  video+poster restored, and image with no ossKey still cleared. The renderer
  snapshot is mocked so the frame path runs in plain Node.

cc5a6ab152 feat(agent): edit_elements — NL → EditIntent vertical (#895) (#896)
* feat(agent): add edit_elements NL → EditIntent vertical (#895)

Give the editing surface its first real consumer: natural-language
per-element style/geometry edits flow through the same EditIntent
vocabulary as pointer gestures, with an all-or-nothing validation gate
and one undo entry per instruction.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(agent): harden edit_elements against CR findings (#895)

Re-validate intents at apply time (atomic refuse on missing/locked ids),
type-check prop values, require an open edit session for undo, clamp line
stroke width correctly, enforce group cohesion, nest shape text chrome,
and surface refuseReason on the tool card.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(agent): close remaining edit_elements CR residuals (#895)

Feed apply outcomes into next-turn history and post-run chat corrections,
phrase tool success as proposed-not-applied, and tighten gradient/filters/
enums/per-type value validation plus label-less shape text refusal.

Co-authored-by: Cursor <cursoragent@cursor.com>

* refactor(agent): derive edit_elements prop validation from the DSL schema (#895)

Three review rounds each found a hand-written validator disagreeing with
the DSL contract (a gradient pos range pinned at [0,1] against the
percent contract, a textType enum matching the DSL in neither direction,
per-type ownership gaps like vertical-on-shape and color-on-everything).
Replace the class instead of the instances:

- The gate now loads the dsl-generated JSON schema
  (@openmaic/dsl/schema/scene.schema.json) and validates every proposed
  prop value against the target element type's subschema via a compact
  schema-subset checker — per-type ownership, enums, and structured
  shapes (outline/shadow/gradient/filters) come from the single source
  of truth and stay correct as the DSL evolves.
- Explicit policy layers stay on top: the content/identity blocklist
  (schema would allow what policy forbids), geometry clamps (coords,
  min sizes, line stroke width), and a numeric-range overlay for what
  plain number types cannot express — gradient stop pos is a percent in
  [0,100] (the previous [0,1] check refused canonical gradients and the
  unit test pinned the wrong contract), fontSize/lineHeight/radius
  bounds, filter value length, stop-count cap.
- Consequences: color is refused on types that do not render it, with
  prompt guidance steering text color to defaultColor and shape body to
  fill; fill on charts is now allowed (the schema has it; the inventory
  already advertised it); textType accepts the full DSL enum.
- Apply-time revalidation also refuses element-type drift via a
  gate-time targetElementTypes map carried in the tool details.
- Refusal reasons render as visible card text, not only a hover title.
- Test pins added for all of the above plus selection scoping, coord
  bounds, non-finite rotate, and empty batch/props.

* fix(agent): harden the schema-derived gate — fail closed, assert schema source, unify numeric clamping (#895)

- A schema construct the subset checker cannot judge (unresolved $ref,
  malformed anyOf, unsupported keywords) now refuses instead of
  accepting — the gate fails closed on the unknown.
- A module-load assertion verifies the loaded dsl schema carries every
  definition the gate maps and a sane TextType enum, so a stale or
  missing build artifact fails loudly with a rebuild hint instead of
  validating an outdated contract silently.
- Numeric-overshoot convention unified and documented: structural,
  enum, or ownership mismatches refuse (teaching the model the
  contract); numeric overshoot on a valid prop clamps (matching gesture
  behavior) — opacity now clamps like geometry.

Yanpeng Wangandwyuc 9670100363 feat(extraction): media (audio/video) extraction + AliDocMind provider (#887)
* feat(extraction): add AliDocMind provider + media extraction abstraction

Adds AliDocMind (Aliyun Document Mind LLM version) as a new vendor
alongside unpdf/MinerU, and introduces the media (audio/video) extraction
layer that mirrors the document extraction one.

Document side (file: pdf/docx/pptx/xlsx/images):
- PDF_PROVIDERS gains an `alidocmind` entry; parseWithAliDocMind() maps
  layouts[] -> ParsedPdfContent. Flows through the existing document
  extractor registry, so AliDocMind is selectable anywhere MinerU is.
- PDFParserConfig / DocumentExtractorConfig gain accessKeyId/accessKeySecret
  (AliDocMind uses AK/SK, not a single apiKey); env fallback via
  ALIDOCMIND_ACCESS_KEY_ID / ALIDOCMIND_ACCESS_KEY_SECRET.

Media side (mp4/mp3/wav/... -> MediaArtifact):
- New lib/media-parse/ domain mirroring lib/pdf/ (types/constants/providers).
  parseMedia() maps AliDocMind segments[]/audio_frames/video_frames ->
  MediaArtifact (transcript + keyframes).
- MediaExtractorProvider interface + media registry + extractMedia() entry,
  symmetric to DocumentExtractorProvider / extractDocument().
- MediaArtifact and the ExtractionResult/Artifact/Error/Job envelope live in
  lib/document/types.ts (re-exported from @/lib/document).

Shared AliDocMind SDK wrapper (lib/pdf/alidocmind-client.ts) handles the
submit -> poll -> get flow for both sides via @alicloud/docmind-api20220711.

Tests: env-gated smoke test (tests/document/alidocmind.smoke.test.ts) drives
a real PDF and a real video through AliDocMind; media-artifact type test;
extractor-registry test updated for the new provider.

Part of #621 (MAIC ETL). Media extraction is the sibling to the document
extraction landed in #741.

* feat(extraction): wire AliDocMind AK/SK through settings UI + routes

Surfaces AliDocMind in the (post-#837) Document Parsing settings panel as a
peer of unpdf/MinerU — one panel, one credential entry, more supported
formats. Threads Aliyun AccessKey ID/Secret from the store through the
extraction routes.

- Store: pdfProvidersConfig + setPDFProviderConfig gain accessKeyId/accessKeySecret;
  default alidocmind entry added.
- pdf-settings.tsx: AliDocMind branch renders AccessKey ID + Secret inputs
  (secret masked with show/hide) and a Test Connection button; request-URL
  preview shows the DocMind endpoint. Provider auto-appears in the panel via
  PDF_PROVIDERS; supported-format badges come from #837's registry
  (ALIDOCMIND_MIMES added to lib/document/mime.ts).
- verify-pdf-provider route: alidocmind branch verifies AK/SK via a lightweight
  authenticated probe (verifyAliDocMindCredentials) — auth-level errors fail,
  anything else passes.
- extract-document route + generation flow (app/page.tsx, generation-preview):
  accessKeyId/accessKeySecret carried through session → FormData → config.
- i18n: alidocmindAccessKeyId / alidocmindAccessKeySecret in 8 locales.
- Icon: reuse /logos/bailian.svg (Aliyun family) instead of a missing asset.

Verified end-to-end against the running app: AliDocMind panel renders,
Test Connection returns "连接成功" through the real Aliyun API.

Part of #886.

* feat(extraction): route audio/video uploads through extractMedia() (reuse document path)

Media uploads now flow through the same upload picker, /api/extract-document
route, and generation pipeline as documents — no separate upload area. Only
the extraction differs: media mimes dispatch to extractMedia() -> MediaArtifact,
which is flattened to the text shape the generation pipeline already consumes.

- mime.ts: register audio/video formats in DOCUMENT_FORMATS (accept string,
  extension map, badges resolve for them); add MEDIA_PROVIDER_SUPPORTED_MIME_TYPES
  + SUPPORTED_MEDIA_MIME_TYPES, kept separate from PROVIDER_SUPPORTED_MIME_TYPES
  so the document drift-guard stays document-only. mimesForProviders() folds in
  a provider's media mimes, so the existing upload helpers
  (getAcceptStringForProviders / isMimeSupportedByProviders / format badges)
  cover media automatically when the provider supports it.
- extract-document route: media mimes dispatch to extractMedia(); MediaArtifact
  flattened to timestamped text (synopsis + transcript + keyframes).
- Tests: 6 media cases in mime.test.ts (accept/validation/badges/normalization).

Verified: uploading a real video through the route returns synopsis +
timestamped transcript/keyframes as text (curl, real AliDocMind key).

Part of #886.

* feat(extraction): use Alibaba Cloud icon for AliDocMind provider

Replace the placeholder bailian.svg with a dedicated Alibaba Cloud icon mark
(the square symbol from the official wordmark, text removed) so the provider
reads as Aliyun rather than Bailian. Square aspect matches the other provider
icons. Source: Alibaba Cloud / Alibaba Group brand assets.

* style: prettier format AliDocMind + media extraction files

* fix(extraction): harden AliDocMind — SSRF guard, cred verify, env gate, table text

Addresses review findings on the AliDocMind provider:

- SSRF (high): the media branch of /api/extract-document now runs the same
  validateUrlForSSRF check on a client-supplied baseUrl as the document branch,
  so an audio/video upload can't point the server's Aliyun SDK at an internal
  host.
- Credential verify (high): verifyAliDocMindCredentials now whitelists success
  signals instead of blacklisting auth errors. Probed against the real API:
  valid creds + bogus job returns a no-throw "BizIdNotExistOrResultExpired"
  body; invalid creds throw InvalidAccessKeyId.NotFound. Only a no-throw
  response or a "biz-not-found" business error counts as valid — an unreachable
  endpoint, a localized error, or throttling now correctly reports failure
  instead of a false "connection successful".
- Env-fallback gate (med): resolveCredentials no longer reads
  ALIDOCMIND_ACCESS_KEY_ID/SECRET unconditionally. Env fallback is opt-in via
  allowEnvFallback, which the route sets only for a server-managed provider, so
  an unauthenticated client request can't silently run on the server account.
- getDocParserResult error body (med): fetchResult throws on a non-200 result
  envelope instead of returning {} (empty text presented as success).
- Media pagination (med): stop after the first page when segments[] are present
  — layoutNum/layoutStepSize address layout blocks, not media segments, so
  re-requesting would loop over the same segments to the safety cap.
- Table content (med): tables/charts carry content in llmResult, not
  markdownContent; the layouts→text mapping now prefers llmResult for those
  types so table content isn't dropped (tables: true was advertised).
- Dead code: remove getCurrentMediaParseConfig (referenced non-existent store
  fields; the single-panel UI reuses pdfProvidersConfig).
- Dedup: media MIME list lives only in lib/document/mime.ts
  (ALIDOCMIND_MEDIA_MIMES); the media registry imports it.
- Tests: smoke test asserts durationMs is in ms (>1000 for a ~52s clip) to
  guard a ms/s unit mismatch; uses allowEnvFallback for the env-cred path.

Verified with the real key: PDF + video smoke tests pass; verify classifies
valid vs invalid creds correctly.

Part of #886.

* feat(extraction): extract AliDocMind images to base64 (parity with unpdf/MinerU)

AliDocMind embeds figure/picture image URLs inside each layout's
markdownContent (markdown `![](oss-url)`), not a dedicated field, and the URLs
are short-lived OSS signed links. Previously we emitted `images: []` and left
the expiring URLs inside the extracted text.

Now, for figure/picture layouts we:
- parse the OSS image URL out of markdownContent,
- fetch it at extraction time (before the signature expires) and re-encode to
  PNG base64 via sharp — the same base64 `images[]` contract unpdf/MinerU
  produce, so downstream storeImages → IndexedDB → slide works unchanged,
- populate metadata.pdfImages + imageMapping (the generation flow prefers
  pdfImages),
- strip the remote-URL markdown from the emitted text so expiring links don't
  leak into the prompt.

Downloads run concurrently; a failed/`sharp` image is dropped, never failing
the whole parse. Also fixes the prior over-broad table handling: only `table`
blocks read llmResult; `figure` is treated as an image (chart-figure llmResult
still kept in text).

Verified with the real key: a sample PDF yields 24 base64 images in both
images[] and metadata.pdfImages, and no oss-cn-hangzhou URLs remain in text.

Part of #886.

* docs(test): note AliDocMind video smoke test is non-deterministic server-side

* fix(extraction): correct AliDocMind pageCount (pageNum is 0-based)

Verified against a real response: AliDocMind reports pageNum 0..13 and
pageCountEstimate 13 for a 14-page document — both are 0-based. The metadata
pageCount previously used pageCountEstimate directly, undercounting by one.
Use the already-1-based maxPage, falling back to pageCountEstimate+1 only when
no blocks were seen. Document the 0-based convention at the normalization site.

* fix(extraction): address AliDocMind review — verify/SSRF/config/media (P1+P2)

Resolves all P1/P2 findings from the cross-review on #887.

P1 (blocking):
1. verifyAliDocMindCredentials now inspects the no-throw response body.code.
   An OSS-only key returns NoPermission without throwing; previously that was
   green-lit as "connection successful" then failed at extraction. Only a
   success/200 or the job-not-found probe code is accepted. Deterministic
   mocked test added (tests/document/alidocmind-verify.test.ts).
2. verify route trust boundary: managed → server-owned AK/SK + default endpoint
   only (ignore client values); unmanaged → client creds only, never env
   fallback, and the client endpoint is SSRF-validated before signing.
3. image fetch hardened: restricted to Aliyun OSS hosts, redirects disallowed,
   per-image byte cap, image-count cap, bounded concurrency (was unbounded
   Promise.all over provider-returned URLs).
4. AliDocMind is now selectable in the generation toolbar — availability
   recognizes the AK/SK pair, not just apiKey.

P2 (correctness):
5. Explicit server-config for the AK/SK pair (applyAliDocMindFallback +
   resolveManagedAliDocMindCredentials); verify and extract now resolve
   managed/env identically instead of verify-uses-env / extract-rejects.
6. Poll loop checks body.code before status, so a body-level error (e.g.
   NoPermission) fails fast instead of retrying for the full 15 min.
7. Image page numbers preserved through fetch/filter — no longer hard-coded to
   page 1, so multi-page image→page association is correct.
8. Empty media extraction (no synopsis/transcript/keyframes) returns 422
   PARSE_FAILED instead of HTTP 200 with empty text.
9. Format matrix trimmed to the official contract: images JPG/JPEG/PNG/BMP/GIF
   (dropped WebP/JP2), media MP4/MKV/AVI/MOV/WMV/MP3/WAV/AAC (dropped M4A).
10. A document-only provider (unpdf/mineru) uploaded with a media file now
    returns a clear 4xx instead of an opaque 500.

P3: credential-verify failures return INVALID_CREDENTIALS 4xx (not
INTERNAL_ERROR 500); formatTimestamp emits HH:MM:SS past one hour.

Verified with the real key: verify classifies valid→ok and invalid→fail; PDF
(24 images, correct page numbers) and MP4 extraction pass end-to-end.

* fix(extraction): make AliDocMind selectable + correct analysis label for media

Two UI/UX fixes found while manually testing the AliDocMind flow end-to-end:

- Persisted-state backfill: add ensureBuiltInPDFProviders so a PDF/document
  provider added after a user's settings were persisted (AliDocMind) is
  backfilled into pdfProvidersConfig on rehydrate. Without it the provider
  never appeared in the store, so it couldn't be selected and never picked up
  its server-configured flag. Wired into both persist migrate() and merge(),
  mirroring the existing image/video/web-search backfills.

- Analysis step label: getGenerationStepText showed "解析 document 文件" for
  audio/video (the type map fell through to the literal "document"). Documents
  keep their precise token (PDF/DOCX/PPTX/XLSX/images); audio/video now use a
  dedicated, locale-correct string (generation.analyzingMediaMaterial, added to
  all 8 locales) instead of forcing a format token into the "{{type}} 文件"
  template.

Manually verified end-to-end (real key): PDF, MP4, and MP3 (audio extracted
from the sample video) each extract and drive full course generation; a
DocMind-restricted AK/SK (OSS-only) now correctly fails verification with
NoPermission (400) instead of a false "connection successful".

* fix(extraction): address 2nd-round AliDocMind review (managed creds, stream cap, empty verify)

Resolves the three follow-up findings on #887:

1. [P1] YAML-managed AliDocMind creds now reach extraction. Both extract paths
   (document + media) previously cleared the managed AK/SK and relied on an
   env-only fallback, so a YAML-only deployment verified but failed to extract.
   They now resolve server-owned creds via the shared
   resolveManagedAliDocMindCredentials() (env OR YAML), matching the verifier.
   Regression test added for YAML-only creds with no ALIDOCMIND_* env.

2. [P1] Image download is now size-capped while streaming. Instead of buffering
   the whole response and checking length afterward, the body is read chunk by
   chunk with a cumulative byte count that aborts the moment it exceeds the cap
   — a missing/false Content-Length can no longer exhaust memory. Host allowlist
   tightened to oss-*.aliyuncs.com. Tests: non-OSS host refusal, no-Content-Length
   overflow abort, declared-oversize rejection.

3. [P2] Empty verification body no longer counts as success. Removed the
   codeStr === '' branch from the positive-signal whitelist (a working key
   always returns the job-not-found business code for the bogus probe id).
   Regression test added for empty and absent bodies.

Rebased onto main (package.json: kept @openmaic/storage + AliCloud deps).
Verified with the real key: PDF + MP4 extraction still pass end-to-end.

* fix(extraction): merge AliDocMind AK/SK into a baseUrl-configured YAML entry

Follow-up to the YAML-managed credential fix. When a YAML `pdf.alidocmind`
entry also specifies `baseUrl`, the generic loadEnvSection() (pdf requires a
baseUrl) creates the pdf.alidocmind entry copying only apiKey/baseUrl/models/
proxy — never AK/SK. applyAliDocMindFallback() then returned early because the
entry already existed, so the provider was "managed" but had no usable
credentials, and resolveManagedAliDocMindCredentials() returned undefined
(verify + extract both silently lost the creds).

Merge the AK/SK into the existing entry instead of returning early. Added a
regression test with baseUrl + accessKeyId + accessKeySecret together (the
previous test omitted baseUrl, so the generic loader skipped the entry and the
bug was masked).

* fix(extraction): don't mark AliDocMind managed without AK/SK; align poll code check

Two edge cases from a follow-up adversarial pass:

- [MED] A YAML `pdf.alidocmind` entry with `baseUrl` but no AK/SK (and no env
  AK/SK) made the generic loader create the entry → isServerConfigured=true
  (managed) → but resolveManagedAliDocMindCredentials() returned undefined, so
  the provider was locked out AND client-entered AK/SK were silently dropped.
  applyAliDocMindFallback now deletes a credential-less entry so the provider
  stays UNMANAGED (clients supply their own creds). Regression test added.

- [LOW] verify accepted a `code: "success"` body but the extraction poll loop
  threw on any non-"200" code — a success-shaped status would pass verification
  then fail extraction. The poll loop now treats "200"/"success" as benign,
  matching verifyAliDocMindCredentials.

Yizuki_AmeandClaude Fable 5 e136c81c03 chore(generation): remove dead legacy pipeline chain (#904) (#905)
Remove the generation-pipeline leftovers orphaned since the old
/api/generate route was deleted in 0610053:

- pipeline-runner.ts (runGenerationPipeline / createGenerationSession)
- generateFullScenes + generateSingleScene in scene-generator.ts
- unreachable callbacks param of generateSceneOutlinesFromRequirements,
  including its five hardcoded Chinese statusMessage strings
- generating-progress.tsx (never imported since the initial commit)
- orphaned GenerationCallbacks / GenerationProgress / GenerationSession
  types, 5 unused i18n keys across all 8 locales, and stale
  generateFullScenes references in DESIGN-regenerate-scene.md

Found while investigating #884. Verified against a pre-change baseline:
tsc --noEmit diff clean, vitest failure set unchanged (1956 passed),
check:i18n-keys passes, zero residual references repo-wide.

Yanpeng Wang d54e62f5c4 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
