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.

* refactor(storage): drop the unused active-stage API from the agent-session contract

Tools address stages explicitly on every call, so the store keeps no
mutable session-level stage pointer. Removes resolveActiveStage and
setActiveStage from the store interface, their PG implementations, the
active_stage_changed lifecycle event, the session_active_stage owner
event variant, and the contract tests pinning them. The active_stage_id
column and the DDL check constraint stay untouched for schema
compatibility.

* 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.

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

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

* fix(workbench): label the folder and rename tools on the timeline

* fix(workbench): label the roster and voice tools on the timeline

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

* ci: retrigger

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

* fix: forward the freshness manifest through the owner-bound store

* feat(workbench): add the Pro entry points and preserve the mode-transition semantics (#1208)

* feat(workbench): add the Pro entry points

* feat(workbench): preserve Pro mode transition semantics

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

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

* feat: port workspace shell sibling modules

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

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

* docs: keep ported comments in English and deployment-neutral

* docs: announce 1.0.0 and refresh the feature overview (#1216)

* docs: announce 1.0.0 and refresh the feature overview

* docs: finalize 1.0.0 README after feature merge

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Covers the three restored entry points:

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

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

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

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

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

Port the reference's LISTEN/NOTIFY delta path:

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

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

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

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

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

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

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

Bumps @openmaic/storage to 0.18.0.

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

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

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

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

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

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

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

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

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

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

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

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

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

Bump @openmaic/storage to 0.18.0.

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

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

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

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

* fix(workbench): 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.

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.

* chore(storage): bump version to 0.1.1 for README doc alignment

The README is a publishable input, and the no-migration doc alignment
changed it, so the package version must increase. Patch bump: documentation
only, no code or API change.

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.

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.

* 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.

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.

wyuc e83db6a531 fix(agents): persist AgentBar voice picks and mode/selection across reloads (#723)
* feat(audio): let resolveAgentVoice honor per-agent voice overrides

* feat(settings): persist per-agent voice overrides

* fix(agents): persist AgentBar voice picks via settings overrides

* fix(classroom): keep user's agent mode and selection across loads

* fix(agents): only carry user-set agent selection across classrooms

Review follow-ups: stage-derived defaults written by a classroom load were
re-read as a user choice on the next load, so visiting a preset classroom
permanently downgraded auto classrooms to preset agents. Track the origin
with a persisted agentSelectionIsUserSet flag (set by AgentBar interactions,
cleared by fallback writes). Also: voice overrides are now clearable
(undefined deletes), the override type is single-sourced in voice-resolver,
and persist rehydration of the new fields is pinned by tests.

* fix(agents): don't mark stage-derived selections as user choices

Round-2 review: clicking the already-active mode tab no longer flags the
selection as user-set (a visual no-op must not promote stage defaults to a
choice), generation-preview clears the flag when it writes the generated
roster, and tests now pin that setter writes actually reach storage.

* fix(agents): restore generated agent selection when switching back to Auto

Review follow-up (#723): handleModeChange('auto') left the preset ids
selected, so the UI said Auto while discussion playback kept using preset
agents, and the persisted user-set auto pair could never validate on
restore. Switching to Auto now selects the loaded classroom's generated
agents (empty when none are loaded, falling back to stage defaults on the
next classroom load).

wyucandClaude Opus 4.8 47d28145b4 feat(maic-editor): slide surface — MAIC Editor v0 (epic #562) (#615)
* feat(maic-editor): framework primitives + edit StageMode (#564)

* feat(maic-editor): framework primitives + edit StageMode

Phase 1 framework foundation for the MAIC Editor (RFC #547,
tracking #560). Plumbing only — no UI consumers ship in this
sub-PR; the EditShell chrome and slide surface registration
land in follow-ups.

- StageMode gains 'edit' alongside 'autonomous' | 'playback';
  setMode resets canvas selection when leaving 'edit'.
- <Stage> auto-exits 'edit' whenever the current scene becomes
  uneditable (no scenes / pending generation / no current
  scene) so a follow-up Pro toggle can never strand the user
  in an empty edit shell.
- SceneEditorSurface contract + tiny registry under lib/edit/
  so each SceneType plugs in a surface without the shell
  importing surfaces directly. Surfaces declare CanvasComponent,
  useSurfaceState(), insert palette items, floating actions,
  commands, and (reserved for AI) inline coach hints.
- Slide kernel (lib/edit/slide-ops.ts): immutable, history-aware
  operations covering slide-update, element add / update /
  updateMany / delete / deleteMany / reorder / duplicate / align /
  removeProps, and text content edit.
- Slide element factories (lib/edit/slide-edit-elements.ts) for
  default text / shape / image elements + HTML <-> plain-text
  helpers.
- i18n: stage.editCourse + stage.doneEditing across all 6
  locales, consumed by the header toggle in the next sub-PR.
- Vitest coverage for the slide kernel (operations + history)
  and the edit-mode store transition (entry + canvas reset on
  exit).

PBLRenderer's mode prop is widened from the literal pair to
StageMode so <SceneRenderer> (which already passes StageMode)
type-checks. The prop is unused inside the renderer.

* style(maic-editor): apply prettier to lib/edit + tests/edit

CI runs on PRs to main only, so the prettier check did not fire
for this PR's target branch — applying formatting locally before
the merge train reaches main avoids a follow-up style commit.

* ci: also run on PRs targeting feat/maic-editor-v0

The MAIC Editor lands as a series of stacked sub-PRs against
the long-lived feat/maic-editor-v0 branch. Without this entry,
none of those sub-PRs get a CI gate — style/lint/type/test
regressions only surface when feat/maic-editor-v0 finally
merges back to main, at which point fixing them is a lot more
disruptive than catching them per sub-PR.

Push trigger is intentionally left main-only: nobody pushes
directly to feat/maic-editor-v0, every change arrives through
a PR that now runs the gate.

* fix(maic-editor): address kernel review on #564

Addresses cosarah's review against #561 scope:

Important:
- element.align now uses the canonical lib/utils/element.ts geometry
  helper instead of a forked copy. The local fork ignored
  PPTLineElement start/end and rotation, so bounds were wrong for
  lines and rotated elements.
- Cap slide-edit history at MAX_HISTORY = 50; drop oldest on overflow.
- Narrow slide.update patch to Partial<Omit<Slide, 'elements' |
  'animations'>> via a new SlideMetaPatch alias, so element /
  animation collections can only be mutated through their dedicated
  ops.
- element.add throws on id collision; element.duplicate throws when
  idMap is missing entries or when new ids would collide with
  existing elements.
- scene-editor-registry dev-warns on overwriting a *different*
  surface for the same SceneType (HMR re-register of the same
  instance stays silent); add unregister() for HMR cleanup and tests.

Minor:
- Unify on structuredClone over JSON.parse(JSON.stringify(...));
  inside immer's produce, un-proxy with current() first.
- Skip history push when produce returns the same content reference
  (true no-op detection). element.delete / deleteMany pre-check
  membership so their unconditional filter assignments don't break
  the ref-equality signal.
- Drop redundant cloneSlideContent calls in undo/redo/push paths;
  immer's structural sharing already guarantees immutability of the
  produced output. createSlideEditHistory keeps its defensive clone
  since the initial value comes from outside immer.

Coverage:
- Extract auto-exit predicate into lib/edit/stage-mode.ts so the
  policy can be unit-tested without rendering <Stage>.
- New tests: every align direction, line / rotated element align,
  no-op paths for update/delete/reorder/removeProps/text/align,
  element.add index clamping + id collision, element.duplicate
  default offset + contract errors, history future cleared after
  branching, history capped, registry register/unregister/HMR-safe
  re-register, and the auto-exit predicate.

371 vitest tests pass (was 335). tsc/lint/prettier/i18n/build all
green locally.

* fix(maic-editor): close kernel escape hatches (subagent CR follow-up)

Two defense-in-depth fixes flagged by independent review after the
prior commit:

- element.duplicate now deep-clones the source via
  structuredClone(current(element)). The previous shallow spread
  shared nested mutable references (start/end tuples, outline,
  points) with the source; immer's COW would have handled most
  mutations but ops that operate on nested arrays in place
  (sort/reverse/splice) would silently leak between source and
  duplicate. The deep clone keeps the kernel's invariants
  independent of how downstream op consumers write their recipes.

- slide.update gains a runtime guard that throws when patch
  contains elements / animations. The type-level SlideMetaPatch
  narrowing already forbids these keys, but the runtime guard
  closes the `as any` escape hatch for callers that might bypass
  the type system.

New tests cover both paths: meta-only slide.update succeeds, an
elements-containing patch throws, and a duplicated line element's
start/end/points tuples are independent from the source.

* feat(maic-editor): EditShell chrome and Pro mode toggle (#565)

* feat(maic-editor): EditShell chrome and Pro mode toggle

Adds the scene-type-agnostic editor chrome (EditShell + CommandBar +
FloatingToolbar + HintRail), an edit-mode sidebar, and the header Pro
toggle that flips into the 'edit' StageMode from #561.

No scene editor surfaces are registered yet — the next sub-PR wires up
the slide surface. In this PR every scene type falls through to the
i18n unsupportedScene placeholder, which is the verifiable visible
behavior.

- canEdit gating reuses the canonical isCurrentSceneEditable predicate
  shipped in #561 so the toggle and the auto-exit effect are in
  lock-step.
- handleToggleEditMode tears down live session / engine / TTS before
  entering edit mode.
- ChatArea slides out in edit mode for a full-width canvas.
- reorderScene extracted from EditModeSidebar with unit tests; the
  positional-order preservation is the part worth a guard test.
- i18n scoped to keys this PR's components actually reference;
  surface-specific keys deferred to the slide-surface PR.

* test(reorder-scenes): single-element + reference-inequality cases; zh-CN newSlide distinct from addSlide

CR follow-ups:
- reorderScene tests now cover a 1-element array (both directions
  return null) and explicitly assert the returned array is a new
  reference, not the input.
- zh-CN edit.sidebar.newSlide was duplicating the addSlide label
  ("新建幻灯片" both); using "未命名幻灯片" for the default new-slide
  title to match the English Add slide / New slide distinction.

* refactor(maic-editor): drop EditModeSidebar; clean Pro mode chrome (#568)

Course-correct on #565. EditModeSidebar was rejected by the design
owner as inappropriate for Pro mode (#560 wording is "minimal top
bar + slide thumbnail rail", not a file-list panel). #565 also left
the playback chrome wrapped around the editor — Header / sidebar /
Roundtable / ChatArea all stayed mounted with only the sidebar
swapped, and EditShell's CommandBar/FloatingToolbar/HintRail were
never visible since no surface registers yet.

Drop EditModeSidebar + reorder-scenes helper + tests + the edit.sidebar
i18n block (8 keys x 6 locales) + the CommandBar sidebar-toggle.

Stage keeps Header mounted in both modes — it owns the global Pro
toggle Switch, which is the entry AND exit affordance (closing the
Switch exits; no separate Done-editing button). In edit mode:
SceneSidebar / Roundtable / ChatArea are not mounted, and the canvas
slot renders <EditShell scene> instead of <CanvasArea>. EditShell
internally resolves the surface via sceneEditorRegistry; when none
is registered it falls through to edit.unsupportedScene. With no
surfaces registered, every scene type lands on that placeholder —
the visible v0 behavior.

New optional EditShell.leftRail slot reserves the spot for a
redesigned slide-navigation surface; v0 ships with the slot empty.

SceneRenderer is now playback-only — the mode === 'edit' branch and
its sidebarCollapsed / onToggleSidebar props moved up to EditShell /
Stage.

* feat(maic-editor): enablement infrastructure (pre-slide-surface) (#571)

* feat(maic-editor): enablement infrastructure (pre-slide-surface)

Pre-requisite for the slide surface (#562). Ships the safety
infrastructure so each subsequent surface PR is small and
recoverable:

1. Feature flag NEXT_PUBLIC_MAIC_EDITOR_ENABLED, default OFF —
   gates the Pro toggle in Header. StageMode unchanged.

2. SlideContent.schemaVersion + pure idempotent migrateSlideContent
   / migrateScene; setScenes / addScene funnel legacy data through
   the migrate at the store boundary.

3. tests/edit/round-trip/ harness: apply ops -> buildPptxBlob ->
   JSZip parse -> assert content survived. No PPTX -> Slide reimport
   exists in the codebase, so the full reimport-diff shape isn't
   doable; per-op assertions extend the harness in #562.
   buildPptxBlob is now exported (hook is still the only runtime
   caller).

4. Per-scene slide-history persistence helpers (persist / load /
   has / clear, keyed maic-editor:slide-history:${sceneId}, swallow
   storage failures) + standalone SlideHistoryRestorePrompt dialog
   + 4 new i18n strings x 6 locales. Stage wiring deferred to #562.

5. Concurrency guards: isSceneEditLocked predicate (defensive; no
   current call path structurally hits it); localStorage-backed
   multi-tab edit lock with tryAcquire / refresh / release / heldByOther,
   stale-lock takeover after 3x heartbeat; standalone
   MultiTabEditConflictPrompt + 3 new i18n strings x 6 locales.
   Stage wiring deferred to #562.

The slide-surface PR owns the edit-entry effect machinery (where
the history-state lifecycle and per-tab tabId ref naturally live),
so shipping half-wired dialogs here would speculatively build Stage
state we know we'll restructure on contact with the surface.

* fix(maic-editor): migrateSlideContent forward-compat — no silent downgrade

CR follow-up: previously, content with schemaVersion newer than
CURRENT (e.g. v2 written by a future client) was silently truncated
back to the current version. Now: if schemaVersion >= CURRENT, return
the content untouched. The slide may not render correctly on an older
client, but its on-disk shape stays intact for the next compatible
client to read.

* feat(maic-editor): slide surface skeleton + #571 wiring + geometry (#562) (#579)

PR1 of the slide-surface work (infra-first slice). Registers the slide
SceneEditorSurface so EditShell lights up Pro mode for slide scenes.

- SceneEditorSurface impl + sceneEditorRegistry registration; the surface
  owns a SlideEditHistory via the #564 kernel.
- Reuse the unmodified slide renderer Canvas through a surface-owned
  scene context; geometry drag/resize/rotate commits funnel into
  element.update ops (scene-edit bridge), one gesture = one undo step.
- Geometry numeric x/y/w/h/rotate popover as the precise fallback; gated
  off for line elements (PPTLineElement omits height/rotate).
- Wire #571 infra: cross-tab edit lock + conflict prompt, slide-history
  persistence + restore prompt, regen-lock guard.
- Renderer-commit classification: a real geometry gesture commits
  synchronously inside a pointer interaction; the renderer's
  ResizeObserver text-normalization commits with none, so it is folded
  into the baseline (no undo step / no persist / no spurious restore
  prompt on entry) instead of being staged as a user edit.
- Per-op round-trip test for element.update geometry; bridge + session
  unit tests; edit.geometry i18n across all 6 locales.

Upstream-shared changes are kept minimal and additive: an optional
`controller` prop on SceneProvider (uncontrolled/playback path
unchanged) so staged edits don't write through to the live stage store,
and a FloatingToolbar trigger-nesting fix (it wrapped PopoverTrigger
around <Tooltip>, a provider, so no popoverContent action could open).

* fix(maic-editor): CommandBar insert popover never opened (PopoverTrigger wrapped a Tooltip provider)

Insert→Image was unreachable: InsertButton wrapped <PopoverTrigger asChild>
around <Tooltip> (a context provider, no DOM node), so Radix's Slot bound
no element. Chain both triggers onto the real <button>, exactly mirroring
the PR1 fix already in FloatingToolbar's ActionButton. PR2's insert-image
is the first popoverContent InsertButton consumer to exercise this path.

* fix(maic-editor): text property bar no longer clips/overflows in the floating popover

The ~450px single-row bar was jammed into FloatingToolbar's fixed w-72
(288px) PopoverContent and clipped. Let the popover size to content
(w-auto, max-w-[92vw], Radix handles edge collision) and harden the bar
row (w-max + no child shrink, fixed-width font select) so it renders as
one clean line. Chrome/surface layout only — no renderer change.

* fix(maic-editor): property bar stays open across consecutive formatting steps

execCommand refocuses the editor after every command; the uncontrolled
Radix popover treated that focus-shift as focus-outside and dismissed,
forcing a re-open of the Text bar for each format action. Prevent
onOpenAutoFocus (don't steal the canvas selection on open) and
onFocusOutside (editor refocus must not dismiss); Escape and pointer-down
truly outside still close it. Chrome-only, no renderer change.

* fix(maic-editor): editor canvas now resolves gen_img_* media placeholders

The editor's interactive ImageElement rendered elementInfo.src raw,
so entering Pro mode on any slide whose image was a generation
placeholder showed a broken-image icon (while playback's read-only
BaseImageElement correctly resolved the placeholder to the generated
objectUrl). Extract the resolution into a shared useResolvedImageSrc
hook so both variants stay aligned. Strictly additive: for any
non-placeholder src (legacy / direct URL / data URL) resolvedSrc ===
elementInfo.src and the media store is not subscribed to. Pre-existing
upstream gap surfaced by PR2 as the first real-user editor consumer —
same shape as the CommandBar popover-trigger fix.

* test(maic-editor): unit-test gen_img placeholder resolution (9 cases)

Splits useResolvedImageSrc into a pure resolveImageSrc function (no
hooks) wrapped by the hook, so the resolution logic can be unit-tested
in vitest's plain node environment (no jsdom/RTL needed in this repo).
Covers: done→objectUrl; no task→raw; pending/generating/failed→raw;
done with no objectUrl→raw; cross-stage isolation; no-stageId path;
non-placeholder src passes through (the additive contract).

* refactor(maic-editor): auto-save edits to stage store, drop staging UX

Reverses PR1's "staged edits don't write through to the live lesson"
design. The slide-edit-session now writes through every history move
(applyOp / user commit / ResizeObserver normalization / undo / redo)
to useStageStore.updateScene as the canonical source of truth, which
Dexie already auto-persists. The renderer reads from the stage store
via the controller's getSnapshot.

Removes the entire staging surface that has no place in a modern
editor (Figma/Notion/Google Docs have no "unsaved changes" concept):

- DEL  lib/edit/slide-history-persistence.ts  (localStorage layer)
- DEL  tests/edit/slide-history-persistence.test.ts
- DEL  components/edit/SlideHistoryRestorePrompt.tsx  (restore dialog)
- DROP pendingRestore field + restore() action from slide-edit-session
- DROP restorePrompt branch + handlers from useSlideCanvasController
- DROP edit.history.restore.* keys across all 6 locales

Edits now flow: user input → renderer onUpdate → controller.updateSceneData
→ slide-edit-session.commitContent → writeThrough(useStageStore.updateScene)
→ Dexie. There is nothing "unsaved" to restore, by design.

The session retains its in-memory undo/redo history (per Pro session)
and the user-vs-ResizeObserver gesture classification (so reflow
doesn't push undo steps).

Test suite rewritten to assert write-through on every history move and
no write-through on seed (the stage already has that content).

* fix(maic-editor): address PR review — element delete affordance + cross-platform fonts

Two issues from review on #586:

1. A selected image/text element couldn't be deleted — the renderer's
   delete lives only in a right-click menu, undiscoverable in Pro mode.
   Add a Delete button to the FloatingToolbar for any single selected
   element (text or image), dispatching the existing element.delete op.
   Button-only, consistent with #560's keyboard-shortcuts deferral.

2. Switching fonts had no effect on macOS Chrome — the property bar's
   font list was a hardcoded SimSun/SimHei set (Windows-only system
   fonts the renderer never loads). Use OpenMAIC's canonical FONTS
   registry (configs/font.ts) — the web fonts the renderer actually
   loads, so a pick renders identically on every platform.

Adds edit.delete × 6 locales + the parity-test key; floating-actions
unit tests for the delete action.

* fix(maic-editor): anchor the bar to the text element node, not the wrapper

Code review caught that #editable-element-{id} is a zero-size absolute

.editable-element-text child, which carries the real geometry. Also correct
the dismiss-behavior comment: the bar is purely selection-driven.

active language (violet accent, matching the editor's Pro-mode accent).
Behavior and the text commands are unchanged.

* fix(maic-editor): curate the font picker to fonts the app actually loads

configs/font.ts listed 29 fonts but the app only ever loads Inter (via
next/font); the other 28 had no @font-face or bundled file, so picking them
silently fell back with no visible effect — and nothing but the format bar
even imports the registry. Trim it to what genuinely renders; the file's
comment records how to restore the rest (wire up font loading first).

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

* feat(maic-editor): load the picker fonts via @fontsource

The font registry listed 29 fonts the app never loaded. Wire up a curated
set that genuinely renders — 思源黑/宋, 霞鹜文楷, 站酷快乐体, and 9 Latin
families — via @fontsource packages (npm-managed, no font binaries in the
repo; CJK faces are unicode-range-subsetted so they download lazily per
glyph range). app/editor-fonts.ts registers the @font-face CSS from the
root layout; configs/font.ts is now the real, honest 14-entry list.

The ~14 commercial decorative Chinese fonts are intentionally left out —
they need self-hosting + subsetting + a licensing review, separate work.

* fix(maic-editor): quote font-family names so spaced/numeric ones work

Picking a font whose family name has spaces or a trailing digit (e.g.
"Source Sans 3") threw `Failed to execute 'check' on 'FontFaceSet'` —
`document.fonts.check(\`16px ${name}\`)` needs the family quoted — and the
fontname mark's toDOM emitted an invalid unquoted `font-family`, so the
font silently never applied. Quote the family in both spots; the mark's
parseDOM already strips quotes, so the attr still round-trips clean.

* fix(maic-editor): make the editing frame pointer-events-none

The clean editing frame is a purely visual full-size overlay, but it was
pointer-events: auto — so it masked the text element's own move cursor,
text cursor, click-to-place-caret and drag-to-move; only a thin uncovered
sliver at the edges still triggered them. The dashed BorderLines it
replaced are thin edge lines, so they never had this problem. Mark the
frame pointer-events-none; the resize/rotate handles are separate and
keep their own pointer events.

* chore(maic-editor): drop the "font is loading" toast

With @fontsource fonts and font-display: swap, a picked font swaps in
smoothly on its own — the "Font is loading, please wait..." toast was
noise (and fired on most CJK picks while a unicode-range chunk loaded).
Remove it along with the now-unused document.fonts.check and toast import.

* feat(maic-editor): move the delete action onto the anchored text bar

A text element's contextual actions now sit together on the anchored bar —
format controls + delete, hugging the element — instead of delete sitting
alone in the top-center FloatingToolbar. buildFloatingActions returns
nothing for text (its FloatingToolbar then renders null); non-text
elements still get their delete there. Delete logic is shared via a new
deleteSlideElement helper.

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

* feat(maic-editor): anchor the delete action for image elements

A selected image element now gets a selection-anchored bar hugging it —
just a delete button (image replace/crop/flip stay in a later sub-PR) —
the same way text elements do. The anchoring shell is extracted out of
AnchoredTextBar into a reusable AnchoredBar, and the delete button into a
shared DeleteButton; AnchoredTextBar and the new AnchoredImageBar are thin
wrappers. useTrackedRect now measures .editable-element-text or
.editable-element-image. buildFloatingActions returns nothing for image
elements too (other element types still get their delete there).

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

* style(maic-editor): tighten the anchored bar padding (p-2 → p-1)

p-2 left a chunky white margin around the content — most visible on the
image bar, a lone delete button in an oversized box. p-1 (4px, the value
the FloatingToolbar used) makes both bars sit snug to their controls.

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

* feat(maic-editor): anchor the delete bar for every element type

The selection-anchored delete bar now covers all non-text element types
(shape, line, table, chart, …), not just image — so every element's
editing chrome is anchored uniformly. AnchoredImageBar becomes the
type-agnostic AnchoredDeleteBar; useTrackedRect matches any
.editable-element-{type} content root; buildFloatingActions is dropped —
the surface no longer contributes top-center FloatingToolbar actions,
everything is on an anchored bar.

* fix(maic-editor): show legacy font names in the picker trigger

When a text element's `fontname` was a value not in the curated FONTS
registry (e.g. `Microsoft YaHei`, `PingFang SC`, theme defaults), the
Select couldn't match it and `<SelectValue/>` rendered a blank trigger —
both reviewers (cosarah Important, xuyuanwei678 #1) caught this. Add a
placeholder fallback so the raw family name surfaces in the trigger.

Also clean up the dead `'默认字体'` label that `text-format-bar.tsx`
overrode unconditionally: introduce an optional `labelKey` field on
`FontEntry`, use it for the default entry, and let the picker prefer
the i18n key when present — no more by-value special case.

* chore(maic-editor): address cr minors

- `marks.ts` fontname `toDOM` rejects `"` or `\` instead of interpolating
  them: a hand-crafted mark with `fontname: 'X"; background:url(...);'`
  could otherwise close the quoted string and inject arbitrary CSS.
- `AnchoredBar` gains `onOpenChange` (clears the canvas selection on
  Radix-initiated dismiss): silences the controlled-without-handler dev
  warning, and brings back Esc / SR dismissal that our focus-outside
  hardening had cut off.
- `useSyncEditingElementId` folds two `useLayoutEffect`s into one with
  a cleanup; the previous unmount-only effect was structural noise.

* fix: pin body padding-right so popovers don't reflow the page

Radix Select / Popover wrap with `react-remove-scroll`, which adds a
compensation `padding-right` to <body> when they open. Our <html>
already reserves the scrollbar gutter (`scrollbar-gutter: stable` +
`overflow-y: scroll`), so the compensation added a visible ~15px shift
on every dropdown open. Pin body's padding-right with `!important` so
the page stays still. (xuyuanwei678 review #2.)

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

* fix(maic-editor): surface legacy font names via SelectValue children

The earlier placeholder approach didn't work — Radix's `placeholder` only
fires for an empty `value`, not for an unmatched non-empty one. So an
element with a legacy fontname (e.g. `Microsoft YaHei`, `PingFang SC`,
theme defaults) outside the curated FONTS registry still rendered a blank
trigger. Render the trigger text via `SelectValue` children instead — the
new `currentFontLabel` helper covers all three cases: matched → entry's
i18n / fallback label, unmatched non-empty → the raw family name, empty
→ the default-font label. Unit tests cover each case.

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

* fix(maic-editor): preventDefault on pointer-down-outside so drag/resize work

The onOpenChange handler added to silence the Radix dev warning + restore
Esc dismissal also fired on pointer-down-outside — i.e. on every mousedown
on the selected element to drag it or grab a resize handle. That cleared
the selection before the drag could start, so nothing on the canvas could
be moved or resized. preventDefault on `onPointerDownOutside` (matching
the existing `onFocusOutside` hardening) keeps the bar selection-driven
while leaving Esc as the legitimate onOpenChange path.

* feat(maic-editor): arm-and-place insertion for text boxes

Replaces the "auto-insert at a hidden default position" UX. Click
`Text box` → arms text-insertion: the button takes the violet active
style, and the renderer's existing ElementCreateSelection overlay turns
the canvas cursor into a crosshair. On the canvas:

  - click  → 300×60 box at the click point
  - drag   → a box at the dragged rect

Either way the new box is auto-selected (addElement defaults that on),
and the surface's existing useEditingTextElementId picks it up so the
AnchoredTextBar opens on it. Esc disarms; clicking the armed button
again disarms (toggle).

Completes the text branch in the renderer's `useInsertFromCreateSelection`
(pptist scaffolding left it TODO) and bypasses the 200² square fallback
in `ElementCreateSelection` for the text type (a square wouldn't suit a
text box). `InsertPaletteItem` gains an `active?` field so `CommandBar`
can render the armed style.

* fix(maic-editor): render list bullets in slide text

Tailwind's preflight resets `list-style` to none, so the format bar's
`bulletList` toggle wrapped selected text in `<ul><li>` but no marker
ever appeared — the button looked inert. Scope a list-style restoration
to `.editable-element-text ul/ol/li` so bullets / numbers render in the
slide text without leaking into the rest of the app.

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

* feat(maic-editor): editable font-size input in the text format bar

The size was a read-only `<span>` between the −/+ steppers. Replace with
an `<input type=text>` that mirrors `attrs.fontsize` locally, commits on
Enter / blur (clamped to [8, 96]; non-numeric reverts), and reverts on
Escape. Adds the `edit.text.fontSize` aria-label key in all 6 locales.

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

* fix(maic-editor): force list markers visible (defeat preflight specificity)

The earlier list CSS didn't survive Tailwind's preflight (which also
resets `padding: 0` on `<ul>`/`<ol>`, so with `list-style-position: outside`
the markers had no room to render). Add `!important` on `list-style` and
`padding-inline-start`, and broaden to also match `.prosemirror-editor ul`/
`ol`/`li` in case the markup ever nests differently than expected.

* fix(maic-editor): reset richTextAttrs when the editing element changes

`richTextAttrs` is a single shared store updated by whichever ProseMirror
was last focused. Switching from one text element to another visibly
carried the previous element's toggle states (bold / italic / alignment /
list) on the format bar for a moment — until the new element's
ProseMirror took focus and repopulated the attrs. `useSyncEditingElementId`
now resets the attrs to defaults whenever the editing id changes, so the
bar shows a neutral state during the transition instead of stale.

* feat(maic-editor): replace OS color dialog with a curated palette popover

Clicking the text-color swatch opened the browser's native `<input type=color>`
dialog — off-brand and inconsistent across platforms. Swap it for a
`ColorPicker` popover: a 12-swatch grid covering the common slide-text needs
(4 neutrals + warm + cool) plus a hex input for anything else. Closes on
pick. Selected swatch gets the violet outline; hex input commits on Enter /
blur (reverts if invalid).

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

* feat(maic-editor): replace flat swatch popover with a real color picker

The previous popover was a chunky 12-swatch grid plus a hex input nobody
types into. Rebuild on `react-colorful` (3KB, well-tested):

- SV pad + hue slider for free-form picking, with scoped CSS overrides to
  keep the picker tight (128px pad height) and rounded — not stock.
- OS eyedropper via the EyeDropper API, feature-detected (Chrome / Edge;
  hidden on Safari / Firefox).
- Row of 10 small (18px) common colors at the foot for one-click reach.
- Current-color preview + read-only hex display.
- Hex input dropped entirely — picking is meant to be tactile.

Live preview while dragging; the popover closes on a swatch / eyedropper
commit (not on drag).

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

* fix(maic-editor): keep the color popover open while dragging the picker

Each SV-pad / hue-slider drag tick fires onChange → dispatches the color
command → `editorView.focus()` pulls focus out of the popover into
ProseMirror. Radix's default onFocusOutside path was treating that as a
dismiss, so the popover closed the instant a drag started — clicking
anywhere on the picker shut it. preventDefault on `onFocusOutside`
(mirrors the AnchoredBar hardening) keeps it open; the popover still
closes on swatch / eyedropper commits and on outside-click / Esc.

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

* fix(maic-editor): scope body padding override + gate ColorPicker mid-drag sync

Two follow-ups from a self-CR on the branch:

- `body { padding-right: 0 !important }` was global, overriding Radix's
  `react-remove-scroll` compensation for every Dialog / Sheet / Select /
  Popover across the app. Scope it to a `body[data-maic-editor='true']`
  selector; `SlideCanvas` sets the attribute while mounted. Non-editor
  pages get Radix's default behavior back.
- `ColorPicker`'s `useEffect(() => setColor(value), [value])` mirror
  could race a stale `value` against the user's current pointer position
  mid-drag — a single late round-trip would snap the picker back. Gate
  the re-sync on `isDragging.current` (cleared on `pointerup`); external
  commits (swatch / eyedropper) still sync immediately because they fire
  while no drag is in flight.

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

* chore(maic-editor): polish from self-CR

- Gate the `richTextAttrs` reset in `useSyncEditingElementId` to only
  fire on element-to-element transitions (track previous editing id via
  a ref). The unconditional reset on the first selection briefly flashed
  neutral defaults (color #000, fontsize 16px) before the focusing
  ProseMirror repopulated the real values.
- Doc-comment the text-insertion add-element asymmetry: text uses the
  renderer's `addElement` (because the rect math lives there and we get
  auto-select for free), image uses surface-side `applyOp` (its source
  is the ImagePicker, not a canvas gesture). Both commit through the
  same store, but the text lane doesn't show as a typed `element.add`
  op in the session history — acceptable, now explicit.

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

* chore(maic-editor): listen to every gesture-end channel in ColorPicker

CR round-2 residual nit: the single `pointerup` listener that clears the
drag-gate would silently keep the gate stuck on any browser / emulator
that only emits the older mouse/touch families. Listen on all four
(`mouseup`, `touchend`, `pointerup`, `pointercancel`) — belt-and-suspenders,
no behavior change on the common path.

* fix(maic-editor): preserve image aspect ratio on insert

`createDefaultImageElement` hardcoded the new image's box to 360×220, so
anything not ~1.6:1 (which is almost everything users upload — photos,
screenshots, logos) ended up squashed or stretched the moment it landed
on the slide. Wrap the factory in `insertImageElement` that measures the
source via `new Image()`, then dispatches `element.add` with dimensions
scaled to fit MAX 600×400 while preserving the natural ratio. Load
failure falls back to the factory default so insertion always succeeds.

* chore(maic-editor): drop the now-dead addElement helper

`addElement` was only ever used by the inline image-insert which became

helper resolves the lint warning.

* feat(maic-editor): nav rail, scene management, Pro mode chrome rework (#601)

* feat(maic-editor): slide nav rail + scene management (3/3)

PR3a Phase 1 ships the Pro mode left rail + slide-level management, the
last user-visible block of #562. Closes the gap where Pro mode locked
the user on the current scene with no way to navigate or manage the
deck.

SlideNavRail (Studio Editor aesthetic, mirrors playback `SceneSidebar`
visually — index badge + title above an aspect-video thumbnail card —
so the two sidebars read as the same component family across mode
toggle):

- Vertical thumbnail strip via `motion.dev` `Reorder.Group` with
  drag-to-reorder. `Reorder.Item layout="position"` keeps the layout
  animation on y-axis only; width changes from rail resize don't fight.
- Drag-to-resize handle on the right edge writes `style.width`
  directly on the DOM during the gesture and commits to settings store
  only on mouse-up; matches playback drag feel exactly and skips the
  per-frame `persist` serialization that would otherwise burn the
  frame budget at 60 Hz.
- Collapsed and expanded modes; width and collapsed flag persist in
  `useSettingsStore` (`editRailWidth`, `editRailCollapsed`).
- All scene types are first-class — slides render a live
  `ThumbnailSlide` (now with optional `size` prop → self-measures via
  `ResizeObserver` when omitted, so the rail width is the single source
  of truth), non-slide scenes render the same stylised mockups
  playback `SceneSidebar` uses (extracted to `SceneThumbnailContent`).

Slide management:

- `+ Add` in the rail header inserts a blank slide after the current
  scene; new store action `useStageStore.insertSceneAfter` validates
  stage id, migrates the scene, splices, rebalances `order`, and
  triggers `debouncedSave`.
- Three-dot menu per tile: Rename / Duplicate / Delete. Rename also
  reachable via double-click on the title; Enter commits, Escape
  cancels, blur commits, empty input reverts.
- Duplicate deep-clones slide content with fresh element IDs (avoid
  React key collisions) and a `(copy)` title suffix.
- Delete uses a toast with Undo action; deleted scene is held in a
  small `useDeletedSceneRecycle` zustand store and re-inserted at its
  original index on Undo. Deck-empty guard at the rail layer.
- Inter-thumb `InsertionZone` reveals a violet `+` badge on hover,
  right-anchored, with a popup motion (`cubic-bezier(0.34,1.56,0.64,1)`)
  + drop shadow + `z-20` so it lifts above the active tile's violet
  ring. Zero layout shift.

Chrome bar:

- `HeaderControls` (settings pill + Pro Switch) extracted from
  `Header` so Pro mode can mount it in the CommandBar's trailing slot
  — single top chrome bar in Pro mode instead of stacking Header +
  CommandBar.
- Back-to-home button in CommandBar mirrors the playback Header's
  leftmost button.

i18n: new `edit.nav.*` namespace across en-US / zh-CN / zh-TW / ja-JP

* refactor(maic-editor): split Stage chrome into mode-specific roots

Bug-driven architectural rework. Two symptoms motivated this:

1. Switching from a slide scene to a non-slide one (interactive / quiz
   / pbl) flickered the entire edit chrome — CommandBar and SlideNavRail
   remounted along with the canvas. Root cause: EditShell returned a
   different component type (EditShellWithSurface vs EditShellReadOnly)
   based on whether a SceneEditorSurface was registered for the scene
   type, so React reconciled the change as an unmount/remount of the
   whole subtree.

2. `components/stage.tsx` had grown to 1391 lines — playback engine
   state, chat / TTS / discussion wiring, presentation/fullscreen,
   keyboard handling, AND the edit-mode dispatcher all in one place.
   Any change to mode coordination meant touching this god component.

Changes:

- New `NOOP_SURFACE` (`lib/edit/noop-surface.tsx`) — a no-op
  SceneEditorSurface used as a fallback when a scene type has no
  registered editor surface. `SurfaceState.history` is now optional so
  read-only surfaces can omit undo/redo cleanly. EditShell falls back
  to NOOP for unregistered types.

- EditShell now mounts a single Frame across all scene types. Surface
  state is published from a child `SurfaceStateRunner` keyed by
  `scene.type` (so it remounts only when the runner's hook signature
  changes — rules-of-hooks compliant), with a custom shallow
  equality so the chrome doesn't re-render every render cycle for
  reference-fresh state objects. Result: slide ↔ interactive no longer
  remounts the CommandBar or the leftRail.

- `stage.tsx` → 113 lines. Mode dispatch + cross-tab edit-lock
  coordination + Pro-Switch toggle wiring + multi-tab conflict prompt
  only. Everything else moved into one of two new components:

  - `PlaybackChromeRoot` (`components/edit/PlaybackChromeRoot.tsx`):
    owns the entire playback / autonomous chrome — PlaybackEngine,
    chat, discussion TTS, presentation mode, keyboard shortcuts,
    SceneSidebar, Header, CanvasArea, Roundtable, ChatArea,
    AlertDialog. Exposes `teardown()` via forwardRef so the toggle can
    `await` SSE / engine / TTS shutdown before unmounting it.

  - `EditChromeRoot` (`components/edit/EditChromeRoot.tsx`): the Pro
    mode chrome wrapper — EditShell + SlideNavRail + HeaderControls
    trailing slot. Owns `body[data-maic-editor]` lifecycle (lifted from
    SlideCanvas so it covers read-only Pro-mode scene types too).

- New `StageGrid` (`components/edit/StageGrid.tsx`) — CSS-Grid named-
  slot layout shell with top / left / center / right / bottom areas
  for the Pro mode chrome. Future right panel (properties / AI) and
  bottom timeline plug in as props with no structural code change.
  EditShell's Frame now uses StageGrid internally.

- Deleted `components/edit/SlideTransitionBridge.tsx` (dead code from
  the original A3 transition plan that this rework supersedes).

* refactor(maic-editor): cross-fade chrome roots on Pro mode toggle

Wrap the chrome-root dispatch in `AnimatePresence mode="wait"` with a
180 ms opacity fade-out / fade-in. The outgoing root fully exits before
the incoming one mounts, so:

- The single-canvasStore-writer guarantee from the chrome split is
  preserved (ScreenCanvas and Editor/Canvas never coexist).
- Mode toggle reads as a smooth fade instead of a hard cut.

Stage's outer wrapper now carries the stable `bg-gray-50 dark:bg-gray-900`
background so neither root reveals raw page colour while it passes
through opacity 0. `initial={false}` skips the entry animation on first
mount so the initial playback render is instant.

* feat(maic-editor): drawer-style mode swap transition

Pro toggle was a hard cut — playback chrome vanished, edit chrome
popped into place. Now wraps the swap in `AnimatePresence` with the
two chrome roots layered via `absolute inset-0` so they coexist for
~280ms:

- Edit chrome enters from above (`translateY: -32 → 0`) + fades in,
  giving a "drawer drops down" feel that matches the inner
  CommandBar/leftRail stagger choreography.
- Playback chrome cross-fades opacity-only; no transform so its
  active slide canvas stays put underneath while edit drops over it.

Both roots keep rendering during the overlap, so `canvasStore`'s
scale writer doesn't briefly read zero and snap the slide to a stale
size when one root exits ahead of the other. Duration 280ms /
`CHROME_EASE` matches the inner Frame timing source.

* feat(maic-editor): Pro Switch as a shared layout element across modes

The Pro Switch is the click anchor for the mode swap, but it lives in
two different positions: the 80px playback Header (top-right) vs the
56px edit CommandBar trailing slot (also top-right but at a different
y and with different padding). After the click the switch "jumped" —
it visibly moved + restyled — which felt unsmooth even though the
chrome itself was cross-fading.

Tag the Pro Switch label (and the settings pill) with `motion.layoutId`
so motion treats them as shared elements across the AnimatePresence
swap. During the ~280ms transition, motion measures both instances
and morphs position + size between them — the user's click target
slides into its new home instead of teleporting. Same easing source
as the chrome cross-fade so the two animations stay locked together.

* refactor(maic-editor): unify chrome shell across modes

Pro Switch + settings pill + download icon are the user's mode-toggle
"anchors" — they need to sit at the same screen pixel across
playback ↔ edit. They didn't, because the two chromes had different
shapes:

  Playback: SceneSidebar (left, full height) | Header (h-20, 80px)
            on top of CanvasArea + Roundtable
  Edit:     CommandBar (h-14, 56px, FULL width) on top of a row of
            (SlideNavRail | content), so the rail sat *below* the bar

So when the user clicked Pro, the bar collapsed by 24px AND the rail
shifted down by 56px AND the right-side controls re-styled (compact
variant) — three simultaneous moves. layoutId masked some of it but
the underlying structure was wrong.

Unify the shells:

- `StageGrid` template flipped from `top top top / left center right /
  bottom bottom bottom` to `left top top / left center right / left
  bottom bottom`. The left column now spans all rows so the sidebar
  always reaches the absolute top edge, matching playback exactly.
- `CommandBar` grows h-14 → h-20 + px-5 → px-8, identical to playback
  Header.
- `EditChromeRoot` drops the `variant="compact"` flag on
  `HeaderControls` so the settings pill renders at the same h-9 pill
  it does in playback.
- `SlideNavRail` header replaces the "SCENES" label with the OpenMAIC
  logo (click → home), matching `SceneSidebar`'s shape so the sidebar
  top reads as the same component family in both modes.
- Download / Export dropdown moves out of `Header` and into
  `HeaderControls` so it's present in both playback and edit chrome at
  the same right-cluster position (was previously playback-only).

`Header.tsx` slimmed accordingly. Net effect: the right-edge cluster
(EN, theme, settings, download, Pro Switch) lives at the same screen
pixel across modes; the cross-fade transition only animates the
*contents* inside the bars + sidebar lists, not the bar/rail
positions themselves.

* feat(maic-editor): drop sidebar header + button, add insert-before-first zone

The header `+` was a duplicate affordance — every gap between thumbs
already has its own `InsertionZone`. Remove the header button; insert
flows entirely through the gap zones now (with hover-popup + and
right-anchored visual).

Add one extra `InsertionZone` rendered BEFORE the first thumb so the
top padding of the rail is also clickable / hoverable. Insert-before-
first is implemented inline via `setScenes([blank, ...scenes])`
because the `insertSceneAfter` store API only handles insertion after
an existing anchor.

`PlusCircle` import dropped (no longer used).

* fix(maic-editor): move Download out of settings pill, place right of Pro Switch

Download isn't a settings function (it's an export/share action), so
it shouldn't sit inside the pill that hosts language/theme/settings.
Move it back to a standalone button on the right side of the Pro
Switch — both in playback and edit chrome. Right cluster now reads:

  [ EN · theme · settings ]  [ PRO switch ]  [ Download ]

* feat(maic-editor): floating insert toolbar above canvas (collapsible)

Text box / Image / future shape buttons no longer share CommandBar
with global stage controls (back / undo / redo / title / settings /
Pro Switch / Download). Insert is a content-creation action, not a
stage-navigation one — mixing them blurred the chrome's role.

Lift insert items into a new `FloatingInsertToolbar` that floats
centered ~12px above the slide canvas card. Default expanded; collapse
arrow tucks it into a small chevron handle at the same anchor. State
persists in `settings.editInsertToolbarCollapsed`. Reuses the existing
`InsertButton` (extracted from CommandBar into a sibling module so
both surfaces — the now-removed CommandBar slot and the floating bar —
can share styling).

CommandBar drops its `insertItems` prop / middle slot entirely;
right-side controls collapse to a single `flex shrink-0` cluster
matching playback Header's shape.

i18n: `edit.insert.expandToolbar` / `collapseToolbar` across 6 locales.

* fix(maic-editor): auto-focus text element after toolbar insert

Inserting a Text box via the FloatingInsertToolbar + click/drag on
the canvas left the user one click short — the new element was
selected and the AnchoredTextBar opened, but the ProseMirror editor
never received focus, so the first keystroke went nowhere and the user
had to click inside the element again before typing.

`useEditingTextElementId` already mirrors the surface's editing-target
choice into `canvasStore.editingElementId`. Have `ProsemirrorEditor`
watch that flag in an effect: whenever its own elementId becomes the
editing target (insert, programmatic selection, etc.) and it doesn't
already have focus, push focus into the view. `hasFocus()` guard keeps
this from re-focusing on every re-render of an already-active editor.

* chore(maic-editor): prettier + drop ThumbItem rename sync effect

- prettier --write on three files touched by the recent edits.
- ThumbItem: drop the `useEffect(() => { if (!renaming) setDraft(...) })`
  external-title sync that tripped `react-hooks/set-state-in-effect`.
  Idle display now reads from `scene.title` directly (derived rather
  than mirrored); `startRename` seeds `draft` at session start and
  `cancelRename` resets it so the next session starts clean. Rename
  e2e still passes the menu + double-click + Escape paths.

* fix(maic-editor): CR-loop pass — pointer capture, stage-scoped recycle, equality docs

PR #601 reviewer feedback.

**Drag handle uses Pointer Events with `setPointerCapture`** so the rail
no longer gets stuck in "still dragging" state when the cursor leaves
the window, the OS reclaims focus, or a tab interrupt suppresses the
mouseup that the old document-bound mousemove/mouseup pair relied on.
The handle's onPointerMove/Up/Cancel are now bound directly on the
element; capture guarantees event delivery for the lifetime of the
gesture. Drag tracking e2e still PASS (1 px cursor lock).

**Toast Undo guards stage identity** before re-inserting the deleted
scene. If the user navigated to a different stage while the toast was
up, the recycle entry belongs to the previous stage and
`insertSceneAfter` would reject it on stage-id mismatch — silently
losing the deleted scene. New check drops the undo cleanly when stage
ids don't match. The `stageId` field was already captured on
RecycleEntry; just wasn't consulted.

**`surfaceStateEqual` extended** to compare per-item `id` / `disabled`
/ `label` on `floatingActions` (was length-only) and per-item
`id`/`severity`/`message` on `hints` (was length-only). Today's slide
surface returns `floatingActions: []` and `hints: []` so this is
dormant, but PR3b's z-order actions land in `floatingActions` — pinning
the equality semantics now keeps a future state field from silently
going stale in the chrome. SurfaceState gets a maintenance note
cross-linking to the equality function.

**Header.tsx mode guard comment** updated. The `mode !== 'edit'` guard
around the title block isn't dead — it covers the ~280ms
AnimatePresence exit window where playback chrome is still rendering
its exit animation while mode has flipped to 'edit'. Without the
guard, this title would briefly stack on top of the incoming
EditChromeRoot's CommandBar title during the cross-fade.

* docs(maic-editor): CR-loop round 2 minors — sharpen JSDocs

Round-2 reviewer flagged two doc-only refinements:

- `surfaceStateEqual`: clarify that callback identity (`onInvoke`,
  `popoverContent`) is intentionally NOT compared, and that today's
  safety comes from slide-surface returning `floatingActions: []`
  rather than the per-item compare covering callbacks. A future
  surface that emits closure-capturing actions must fold its own
  change signal into the comparison or the stale callback fires at
  click time.
- `setPointerCapture` catch: spell out that this is paranoia, not a
  real fallback — if capture genuinely fails the gesture still
  tracks for in-window moves but out-of-window `pointerup` won't
  route here. Acceptable degradation; the catch exists only because
  the spec permits an `InvalidPointerId` throw that browsers we ship
  to don't actually emit on same-pointer `pointerdown`.

No functional changes.

* fix(maic-editor): undo restore at index 0, reset mode on classroom load

Two issues from PR #601 manual-verification review:

**Undo of the first slide restored it as the second.** The toast undo
handler clamps `entry.index - 1` to 0 then calls
`insertSceneAfter(scenes[0], entry.scene)`, which lands the entry at
position 1 instead of position 0 — no scene exists before scenes[0] to
anchor on. Fall back to `setScenes([entry.scene, ...live])` when
`entry.index === 0` (or when the deck is empty). The store's existing
non-rebalancing `deleteScene` keeps the surviving scenes at orders
2..N, so the prepended entry's original order=1 lines up naturally;
StageGrid auto-selects the restored scene as current.

**`mode` survived SPA navigation between classrooms.** Refresh reset
mode to 'playback' via the initial store value, but switching
classrooms via Next.js navigation kept the zustand singleton intact;
entering Pro mode in A and then opening B left B in edit mode.
`loadFromStorage` and the server-side classroom-load path both now set
`mode: 'playback'` on every classroom load, normalising the SPA path
to match the refresh path. Mode stays transient UI state, not
persisted with the stage.

e2e: delete Slide 1 → Undo → restored to position 1 (was position 2
before fix).

* feat(maic-editor): gate slide scene creation until inserted scenes are playable (#612)

* feat(maic-editor): gate slide scene creation until inserted scenes are playable

Editor-created slide scenes (blank insert + duplicate) ship without
playback actions, so the playback engine gives them zero dwell and skips
straight past them — a freshly inserted slide is effectively unplayable.
Seeding default actions on new scenes is a separate change; until then,
hide the two scene-creation entry points so the editor stays coherent as
an in-place "fine-tune the generated deck" tool.

- add lib/edit/scene-creation-enabled.ts (SCENE_CREATION_ENABLED=false)
- hide inter-thumb "+" insertion zones (SlideNavRail)
- hide per-slide Duplicate menu item (ThumbItem)
- keep reorder / delete / rename, which are playback-safe

Re-enable by flipping the flag once new scenes get default actions.

* test(maic-editor): e2e guard for slide scene-creation gate

Adds an e2e that generates a classroom (mocked), enters Pro mode, and
asserts the slide rail exposes no insertion "+" zones and the per-slide
overflow menu has only Rename + Delete (no Duplicate). Fails if
SCENE_CREATION_ENABLED is flipped back on without removing the gate.

Two stable test ids support locale-independent assertions:
- slide-nav-insert  (InsertionZone button)
- slide-nav-more    (ThumbItem overflow trigger)

* test(maic-editor): enable editor flag for the e2e webServer

The scene-creation gate e2e needs the Pro Switch, which only renders when
NEXT_PUBLIC_MAIC_EDITOR_ENABLED is on. It's a build-time NEXT_PUBLIC_* flag,
so set it in the Playwright webServer env (applies to `pnpm build` in CI and
`pnpm dev` locally). Fixes the e2e failure on CI.

* test(maic-editor): attach gate screenshot to report instead of fixed path

CR: e2e-artifacts/ is not gitignored, so writing the screenshot to a fixed
path left an untracked file that could be committed by accident. Use
testInfo.attach so the image lands in the (ignored) Playwright report.

* fix(maic-editor): defer editor-only side effects behind Pro mode mount

editor-fonts (~23 @fontsource CSS tables) and slide-surface registration
were top-level static imports in app/layout.tsx and components/stage.tsx,
so flag-off classroom/playback users paid the font-face CSS + slide-edit
module-init cost on every page load.

Move both to a dynamic import in EditChromeRoot (mounts only when
mode==='edit', which requires NEXT_PUBLIC_MAIC_EDITOR_ENABLED). Hold the
EditShell render until the slide surface registers to avoid a NOOP/
read-only flash on first Pro mode paint.

* fix(maic-editor): CR-loop correctness fixes (redo/groupId/edit-lock)

Three confirmed issues from the rebase code-review pass:

- slide-edit-session: a non-user (ResizeObserver auto-height) commit
  updated history.present while preserving a now-stale future, so a
  redo after undo silently resurrected pre-undo content. Clear future
  on the non-user path (present has diverged from the redo branch);
  past is left untouched so no spurious undo step is created.
- slide-defaults: duplicateSlideScene reassigned element ids inline,
  leaving grouped elements pointing at the source slide's groupId.
  Use the existing createElementIdMap so clones get a new shared
  groupId. (Path is gated off today via SCENE_CREATION_ENABLED; fixes
  a latent defect.)
- stage: wrap playback teardown on Pro-mode entry in try/catch and
  release the just-acquired cross-tab lock on failure, so a rejected
  teardown can't strand the lock with the UI stuck in playback.

Adds regression tests for the redo-stale and groupId cases.

* fix(maic-editor): scope editor list-marker CSS to Pro mode

The .editable-element-text ul/ol/li rules used a bare selector, but
that class is the playback text wrapper rendered for every classroom
user — so the !important list-style overrides leaked into normal
playback. Scope them to body[data-maic-editor='true'] (set only while
Pro mode is mounted) so flag-off playback rendering stays unchanged;
markers still show while editing.

* fix(maic-editor): smooth Pro mode transition and stabilize header controls

The Pro mode enter/exit animation janked and the right-side header
controls (settings pill + Pro Switch) drifted in width/position across
the swap. Three causes, all addressed:

- The flag-gating dynamic import gated EditShell behind surfaceReady, so
  the chrome animated in empty and content popped in once the slide-surface
  chunk loaded. Preload the editor chunk (fonts + surface registration) in
  the Pro Switch handler BEFORE flipping mode (lib/edit/preload-editor.ts),
  and drop the render gate — content is present when the animation starts.
- Mode-swap layers and EditShell chrome layers used translateY/translateX
  slides; with backdrop-blur on the rail and pills that forced a per-frame
  backdrop-filter recompute (dropped frames) and, as transform ancestors,
  distorted the layoutId measurement. Switched all chrome enter animations
  to pure opacity fades.
- HeaderControls rendered a fragment whose children were spaced by the
  host's flex gap (Header gap-4 vs CommandBar trailing gap-2), so the
  control cluster changed width/anchor between modes. Wrapped it in a
  self-contained gap-4 container and dropped the cross-bar layoutId morph
  so the cluster is pixel-stable across the swap.

* fix(maic-editor): address review — image insert race, scene migration, i18n staleness

Review feedback from @cosarah on the integration PR:

- Image insert resolved size via Image.onload then applied the op to
  whatever slide session was current at callback time, so switching
  slides before the image loaded inserted it into the wrong slide. Bind
  the insert to the scene active at click time and drop the op if the
  session changed before onload fires.
- Classroom scenes loaded from IndexedDB (loadFromStorage) and from the
  server API (classroom page) bypassed migrateScene, so legacy slide
  content was not normalized with schemaVersion. Both load paths now
  migrate on the way in, matching setScenes/addScene.
- surfaceStateEqual compared insert-item/command id/active/disabled but
  not label/tooltip, so the Pro-mode insert toolbar text stayed stale
  after a language switch. Compare label/tooltip too.
