969574bee4 feat(storage): wire the asset backend into the app (#1007) (#1089)
* fix(persistence): stop corrupting binary response bodies in the route adapter

The embedded persistence route bridges a Node `RequestListener` to the
Fetch API by hand. Its response object is cast with `as unknown as
ServerResponse`, so the compiler checks none of that surface, and two
parts of it were wrong in ways only a byte-carrying handler would hit.

`end` decoded any `Uint8Array` chunk with `Buffer.from(chunk).toString()`,
which is UTF-8. `ServerResponse.end` accepts a `Uint8Array`, and those
bytes are not necessarily valid UTF-8, so every unpaired byte became
U+FFFD -- silent corruption with no error anywhere. The adapter now
buffers chunks as bytes and builds the response from them.

`write` was absent entirely, making any chunked handler a runtime
TypeError rather than a compile error. It is part of the surface this
object claims to implement, so it is now implemented.

Neither reaches a caller today: the document and runtime handlers only
ever end with JSON strings, which took the string branch. Both are traps
laid for the first handler that carries bytes.

Both cases are pinned by tests that fail before this change -- the
binary one on a byte comparison, the chunked one with a 500 from the
TypeError. The existing adapter round-trip test, whose comment already
called this the most bug-prone code in the route, covered only the
string path.

* feat(storage): wire the asset backend into the app (#1007)

The server asset registry shipped with #1007 but was reachable from
nothing: the persistence route never passed an `assetStore`, and no file
under `app/`, `lib/` or `components/` imported the asset server or client
modules. This connects it, additively -- no DSL change, no version bump,
and no behavioural change when server persistence is off.

The route now builds a `PgAssetStore` on the same pool and transaction as
the document store, with `PgAssetByteStore` by default and
`S3AssetByteStore` when `ASSET_S3_BUCKET` opts a deployment into it. The
AWS SDK stays an optional peer, reached only through a dynamic import on
that branch. The offline collector is deliberately not scheduled here,
and the route says so where a reader would look for it, because leaving
it unscheduled grows storage without bound and scheduling it is the
deployment's decision.

On the browser side the asset pool gains a single-shot configuration seam
modelled on the document store's, so that with server persistence enabled
the pool is an `HttpAssetStore` carrying the same auth headers as the
other stores.

Three browser-specific mechanisms needed decisions rather than
translation:

`clearAssetPool` deletes an IndexedDB database today. In server mode
there is nothing local to delete, and a "clear cache" action must not
remove server-side assets -- that would destroy user data from a button
promising to free space. It now revokes local object URLs and closes the
client, and deletes nothing remote.

The cross-tab replacement broadcast is unchanged. Its job is to make
another tab drop a warm object URL when the bytes behind an id change,
and that need is identical in server mode.

The exclusivity proof that decides whether an in-place `replace` is safe
reasons over this browser only: local documents, unflushed state, and a
cross-tab presence probe. In server mode those cover a strict subset of
the holders, since another device can reference the same id and no probe
can see it -- and asking the server who else references an id would be an
existence oracle over other principals. The proof therefore returns not
exclusive unconditionally in server mode, and regeneration takes the
existing fork path. That is the fail-closed direction and a graceful
degradation rather than a break.

The development authenticator had to grow the asset principal's required
`key`; without it every asset request would have been correctly denied.
It derives from the same learner partition, and a principal without one
still gets no asset access. The route now states plainly that this key
comes from a client-supplied header, so the cross-principal isolation the
asset contract describes is not in force under this authenticator -- that
warning previously lived only in the auth module's own header, where
nobody mounting the route would see it.

* fix(storage): close three defects in the asset app wiring (#1007)

**The S3 branch could not load, and isolated nothing.** The route
dynamically imported the storage package's S3 byte store, but that module
statically imported the AWS SDK, so merely resolving it pulled the SDK
into resolution and bundling. The route then separately performed an
ignored native import of the SDK from the app's own scope, which fails
with ERR_MODULE_NOT_FOUND because the SDK lives under the storage
workspace package -- so a deployment that set the bucket got a broken
store rather than an S3 one. There is now one lazy loader in one
resolution scope, the storage module no longer imports the SDK at module
load, and the bucket is validated at initialization rather than treated
as valid because it is non-empty. A test mocks the SDK to throw on
resolution and asserts that importing the byte-store module never
resolves it.

**A cross-tab replacement could leave a mounted lease stale.** The
broadcast handler re-resolves, and `HttpAssetStore.resolve` coalesces
concurrent calls for one id onto a single in-flight request -- correct on
its own, and required by the contract. Together they meant a resolve
triggered by the broadcast could merge into a GET that started before the
peer's replacement, return the old revision, and leave the consumer on
the old URL with nothing to dislodge it. The client gains an invalidation
that retires its cached snapshot and advances the per-id generation
without revoking any URL already issued; `release` would have been wrong
here, since the contract keeps an issued URL valid until its holder
releases it. Removing the invalidation call fails the new race test.

**Clearing a server-backed pool left the closed client installed.** In
server mode `clearAssetPool` closed the client and returned before
clearing the module singleton, so every later `getAssetPool()` handed
back a closed store until a page reload happened to intervene. Only the
IndexedDB deletion is skipped in server mode now; the singleton is always
cleared so the next call rebuilds through the configured factory.

Also adds the tests whose absence let these through: a route round-trip
carrying invalid UTF-8, the SDK-resolution assertion above, the broadcast
race, and reopening the pool after a clear. The earlier tests were not
wrong so much as aimed past the defect -- the route test used JSON text,
and the S3 test injected a loader rather than exercising the imports.

* chore(storage): bump package version to 0.3.0

* fix(persistence): make the route adapter faithful where it carries bytes

The embedded persistence route bridges a Node `RequestListener` to the
Fetch API by hand, and its response object is cast
`as unknown as ServerResponse`, so the compiler checks none of that
surface. Five divergences are closed here; the first two are the ones
that corrupt data, the last three were raised in review.

**`end` decoded bytes as text.** It ran `Buffer.from(chunk).toString()`
on a `Uint8Array` chunk, which is UTF-8, so every byte outside that
encoding became U+FFFD -- silent corruption with no error anywhere. The
adapter now buffers chunks as bytes.

**`write` was absent**, making any chunked handler a runtime `TypeError`
rather than a compile error.

**`write` callbacks ran inline.** Node invokes them after the chunk is
handed off. A handler that writes its next chunk from each callback
therefore recursed synchronously and could overflow the stack, and a
throwing callback threw in the wrong execution phase. They are now
deferred.

**The encoding argument was ignored.** `write(s, 'latin1')` emitted
`0xc3 0xa9` where Node emits `0xe9`, corrupting the body and potentially
invalidating a `Content-Length` the handler had set. Both `write` and
`end` now parse their full overload set and pass the encoding through.
Node's own behaviour for an invalid encoding was established by probing
`ServerResponse` on Node 22 rather than assumed: it throws
`ERR_UNKNOWN_ENCODING` synchronously, so the adapter validates with
`Buffer.isEncoding` and lets `Buffer.from` raise the native error.

**Bodyless statuses were not suppressed.** Node discards writes after
`writeHead(204)` or `writeHead(304)`; this passed the buffered bytes to
the Fetch `Response` constructor, which throws for those statuses, so the
request became a 500 instead of the intended 204 or 304. Buffered data is
now discarded for 204, 205 and 304, and for `HEAD`.

None of the five reaches a caller today -- the document and runtime
handlers only ever end with JSON strings. They are traps laid for the
first handler that carries bytes, which is why they surfaced while
wiring the asset server backend, whose byte routes hit the first two
immediately.

Each is pinned by a test that fails when its fix is reverted.

* fix(storage): keep { client, bucket } working for the S3 byte store

`S3AssetByteStoreOptions.commands` was required and the store's methods
called it directly, so the published `./asset/s3-bytes` export stopped
accepting the `{ client, bucket }` construction it had always taken.
Anyone not going through `loadS3AssetByteStore` either failed to compile
or hit an undefined command factory at runtime.

Make `commands` optional. Omitted, the store resolves the AWS SDK's own
command constructors through a dynamic import on its first `write` /
`read` / `delete` and caches them, so `{ client, bucket }` works again.
Importing the module and constructing a store still never reach the
optional peer dependency: a deployment that does not select S3 never
resolves it. When the SDK cannot be resolved the call rejects naming
`@aws-sdk/client-s3` rather than crashing on an undefined property, and
the resolution is left uncached so installing the dependency fixes an
already-constructed store.

The lazily bound store is run against the byte-store contract, and the
new isolation tests pin both that construction does not resolve the SDK
and that an unresolvable SDK is reported by name.

With the break gone this branch's change to the package is additive, so
the version becomes a patch above main (0.2.4 -> 0.2.5) rather than the
minor it was carrying.

* feat(persistence): run the asset collector in the shipped deployment

`PgAssetStore.remove`, and a `replace` that changes content, only stamp
`asset_blobs.unreferenced_at`. `AssetCollector.collect` is the only path
that deletes anything, and the persistence route deliberately did not
schedule it, on the grounds that scheduling is the deployment's decision.

The deployment this repository ships is docker-compose.yml: the app and
PostgreSQL, and nothing else that could make that decision. "The
deployment decides" therefore meant "it never runs", and ordinary asset
churn retained PostgreSQL bytes or S3 objects forever.

Schedule it from instrumentation.ts, which Next runs once per server
process — a route module can be instantiated more than once and has no
shutdown hook, so a schedule started from one is really started per
instantiation. Next 15 and later pick the file up with no config, so
next.config.ts is unchanged.

Collection is on by default with a 15-minute interval and the package's
one-hour grace period, so the Compose stack is correct with no operator
action. ASSET_COLLECTION_INTERVAL_MS, ASSET_COLLECTION_GRACE_MS, and
ASSET_COLLECTION_ENABLED change or disable it, each documented where it
is read. Without DATABASE_URL nothing is scheduled at all, and a failed
pass is logged and retried on the next tick rather than ending the
schedule or the process.

Several instances may collect concurrently: each candidate blob row is
re-checked and locked FOR UPDATE inside its own transaction, so
collectors serialize on the row rather than racing. The comment says so,
so nobody adds a distributed lock that is not needed.

The byte-store selection moves to lib/persistence/asset-byte-store so the
collector reclaims through the same layer the request path wrote through.
A collector on the PostgreSQL byte store while the route wrote to S3
would drop the blob row and orphan the object permanently.

* feat(storage): bound each collector pass and report whether it filled

An unbounded collect() is sized by however long a deployment ran before
collection was scheduled: one statement selecting every eligible blob,
then a transaction and a byte-layer delete each, in a loop nothing
interrupts. The first pass over the Compose deployment that grew a
backlog before collection was scheduled is exactly that pass.

A pass now takes at most batchSize blobs (default one thousand) and
returns. Ordinary churn between two scheduled passes is far below the
cap, so a healthy deployment behaves as it did when a pass was
unbounded; a capped pass costs the remainder one scheduling interval,
which is what the interval is for.

collect() still answers with the count, and the count alone cannot tell
an empty backlog from a full batch -- a re-referenced or concurrently
taken candidate is skipped, so even a full batch can collect less than
batchSize. collectPass() returns the count together with capped, which
is exactly "this batch was full, run again"; a caller draining a
backlog loops while it is true.

Candidates are taken oldest-unreferenced first, with the content hash
as tiebreaker within one timestamp. Ordering by the hash alone would
starve: digests are uniformly distributed, so a high-sorting blob
waits behind every lower digest stamped after it, and under steady
arrivals those keep coming. The tests pin the ordering against a
planner that happens to answer the right rows without an ORDER BY.

* fix(persistence): keep asset backend faults off the shared handler

Two review findings on the app wiring.

A concrete asset pool instance is single-lifecycle, but
resolveConfiguredAssetPoolStore handed the same object out again after
clearAssetPool() had closed it, reinstalling a dead store as the live
pool. The second handout now refuses loudly and points at the factory
form, which rebuilds on every resolution.

createPersistenceHandler eagerly awaited the asset byte store, so an
invalid ASSET_S3_BUCKET or an unresolvable AWS SDK rejected the shared
persistence handler and took document and runtime traffic down with an
optional backend. Byte-store construction is now deferred to the first
asset byte operation, and a failed construction is not cached, so the
next asset request retries -- the route's own no-poisoned-singleton
rule.

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

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

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

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

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

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

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

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

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

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

Per review feedback, make folders feel complete:

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

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

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

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

Per review (wyuc, CHANGES_REQUESTED):

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

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

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

Per review (wyuc, CHANGES_REQUESTED on 9f77686f):

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

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

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

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

Per review (wyuc, CHANGES_REQUESTED on 19729038):

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

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

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

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

Per review (wyuc, CHANGES_REQUESTED on 860a1170):

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

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

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

* chore: trigger CI after ready-for-review

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

Per review (wyuc, CHANGES_REQUESTED on 37be4716):

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

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

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

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

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

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

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

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

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

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

Two minor findings from cross-review:

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

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

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

Per review (wyuc, CHANGES_REQUESTED on 470f5fea):

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

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

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

Merged with latest main; no conflicts.

wyuc 12814079ba refactor(pbl): consume the contract's PBL project types (#1079)
Third and final PR for #1061. lib/pbl/v2/types.ts becomes a barrel over @openmaic/dsl plus a recursive app-side runtime overlay (plain Omit & Overlay after the dsl contract types were made precise again — index signatures removed, schema tolerance moved into generation post-processing). Write validator byte-identical to base; negative type tests and keyof sentinels pin the contract surface. dsl 0.8.0, storage 0.2.3 (comment-only). Closes #1061.

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

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

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

Closes #392

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

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

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

Addresses the four P2 review findings on #393:

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Second of three PRs for #1061 (after #1070). WidgetType re-exports from @openmaic/dsl; the app's rich widget configs extend WidgetConfigBase; InteractiveContent aliases the contract generic; the write validator adopts the contract's html-or-url rule while staying lenient over historical widget shapes (with a primitive-config barrier matching the hydration crash class); widget-config extraction seeds the contract type; @openmaic/generation drops its WidgetType copy and gains the dsl dependency (0.1.1).

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

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

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

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

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

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

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

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

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

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

* refactor(media): confine reclamation to stage deletion

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

* fix(media): close retry and resolution gaps

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

* test(media): execute the consumer safety matrix

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

* chore(packages): publish the additive DSL field

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

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

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

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

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

* test(media): pin closure safety guards

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

* test(media): narrow rollback element assertion

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

* fix(media): close lease refresh races

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

* fix(media): reopen pool after clear failures

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

* fix(media): isolate shared retry progress

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

* fix(media): close final asset retry gaps

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

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

* fix: preserve actionable retry failures

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

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

* fix(media): hydrate legacy stored video thumbnails

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

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

* fix(media): resolve sole restored legacy video

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

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

* fix(media): scope legacy video recovery

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

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

* fix(media): exclude claimed video recovery tasks

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

* fix(media): unify video element resolution

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

* refactor(media): route legacy recovery through resolver

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

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

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

* fix(export): preserve concrete video sources

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

* fix(media): fork retries without exclusive ownership

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

* fix(media): guard global asset reclamation

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

* fix(media): cover complete slide asset references

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

* fix(media): preserve exclusive retry asset ids

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

* fix(media): revalidate asset bindings at completion

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

wyuc 3ca86aab95 test(pbl-v2): pin single-call prompt goldens and the loop planner's injection seam (#1071)
Follow-up to #1069: golden coverage for all four planner prompt variants (the single-call pair is production's first-priority path), an assertion pinning the loop's injected call contract (toolset, stopWhen, source label, thinking config), plus three review-identified cleanups.

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

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

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

Percyandwyuc d895b8959e feat(classroom): route generate-classroom per stage instead of one model (#1048)
The one-shot generateClassroom path (skill API) resolved the model once
with `resolveModel({ stage: 'generate-classroom' })` and bound that
single `languageModel` into one `sceneAiCall` closure shared by every
scene-content and scene-actions call (and the classroom `aiCall` shared
by outline + agent profiles). As a result, none of the `MODEL_ROUTES`
entries for `scene-content`, `scene-content:<type>`
(slide/quiz/interactive/pbl), `scene-actions`, or `agent-profiles` had
any effect on this path — the browser UI already routes each stage
independently via the /api/generate/* endpoints, but the one-shot API
did not.

Resolve the model per stage instead, mirroring the browser UI:

- scene-content routes via the composite key `scene-content:<type>`,
  falling back to the base `scene-content` route (same resolution as
  /api/generate/scene-content). Interactive widget sub-types are not
  split, only the four core scene types.
- scene-actions routes via the `scene-actions` stage.
- agent-profiles routes via the `agent-profiles` stage (matches
  /api/generate/agent-profiles).
- outline generation keeps using the classroom model, unchanged.

Each stage is resolved lazily and only when a route is actually
configured, so unrouted deployments reuse the classroom model at zero
extra cost. A route that fails to resolve (e.g. an unknown provider)
degrades to the classroom model with a warning, never aborting
generation — the same handling already used for
`web-search-query-rewrite`.

This also fixes a latent bug on this path: PBL scene content generation
needs the resolved `LanguageModel` object (generatePBLSceneContent
drives its own LLM calls through it, not the aiCall closure), but the
call never passed it, so PBL scenes silently returned null and were
skipped. The browser UI already passes it; now the one-shot path does
too — and it also forwards the route's thinking config, so a
`scene-content:pbl` route with a `thinking` block is honored (not just
the model).

The `generate-classroom-scene` telemetry/billing label is preserved on
all scene calls to avoid changing existing logging and accounting;
agent-profiles keeps the `generate-classroom` label.

54f959bb45 fix: render whiteboard math via KaTeX instead of raw LaTeX text (#938)
* fix: render whiteboard math via KaTeX instead of raw LaTeX text

* fix: recognize single-command LaTeX with a braced argument

The fallback missed valid single-command expressions (\vec{v}, \hat{x},
\overline{x}) whose command is not in COMMON_LATEX_COMMAND, because
commands.length < 2 returned null and they rendered as raw text. Now a
single command counts as math when it carries a braced argument, while
path-like prose (C:\temp) still has no braced argument and stays text.
Add regression tests for both cases.

* fix: exclude Windows drive paths before the common-LaTeX-command check

COMMON_LATEX_COMMAND.test() ran before any path-like check, so C:\alpha,
C:\theta and C:\pi were classified as LaTeX and rendered through KaTeX.

Return early for text starting with a drive letter, and add C:\alpha to the
Windows-path regression cases so a path whose segment matches
COMMON_LATEX_COMMAND is covered.

littlebullGitandwyuc 3d85525665 [codex] Add Amazon Bedrock LLM provider support (#538)
* Enable AWS-hosted text models without exposing ambient credentials

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

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

* Give Bedrock a recognizable provider identity

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

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

Nguyễn Lê TrườngandClaude Opus 5 4f20c5151a fix(i18n): translate ASR provider names in the generation toolbar (#1028)
The provider dropdown in the media popover rendered `p.name` straight from
`ASR_PROVIDERS`. That field is a registry label, not a UI string, and
several entries are written in Chinese:

    browser-native  →  浏览器原生 ASR (Web Speech API)
    qwen-asr        →  Qwen ASR (阿里云百炼)

So a user on any non-Chinese locale saw Chinese in the toolbar, while the
settings dialog showed the same providers correctly — it resolves the name
through `t('settings.providerBrowserNative')` and friends.

The id→i18n-key tables move to `lib/audio/provider-display.ts` and both
surfaces use them, so they cannot drift apart again. The settings dialog
keeps its own handling of custom providers, which carry a user-supplied
name rather than an i18n key.

TTS is included in the shared module for symmetry (`doubao-tts` and
`qwen-tts` have the same problem), though the popover's TTS tab is
currently a toggle with no provider list.

Image and video groups in the same popover also render `p.name`, but those
registry labels are already English, so no user-visible string changes;
left alone to keep this focused.

wyuc 091989c48b feat(storage): promote KV HTTP contract + clients to main (Part A of #1000) (#1020)
* feat(storage): KV HTTP contract and clients (#1000 Part A) (#1002)

* feat(storage): KV + Asset HTTP contracts and clients

Adds the client half of the server backends for the two components in the
storage RFC that still had a browser backend only.

Asset contract: the ref is `sha256-<hex>` over the bytes, computed by one
shared rule both backends call, and it *is* the address bytes are written
to (`PUT /assets/{ref}`). The server re-hashes what it received and refuses
a mismatch, so content addressing is enforced end to end rather than
assumed, and uploads become idempotent. `resolve` returns a URL per call,
either an absolute signed URL passed through untouched or a root-relative
proxied path joined to the base origin — the document never stores a raw
URL either way.

KV contract: account scope only, with no scope path segment, query
parameter or body field anywhere on the wire. `HttpAccountKV` is the only
object that can reach it and none of its methods takes a scope, so a
device value is not a request the transport can express; `HttpKVStore`
routes `device` to a local backend it requires at construction. Tests
assert the invariant both ways — `@ts-expect-error` on every scope-passing
call (unused directives fail the build if a scope is ever added) and a
fetch spy proving device traffic does not exist.

Both clients pass the existing `runKVStoreContract` and
`runStorageProviderContract` suites against an in-memory conformance
server, the asset one in both the proxied and signed URL shapes.

* fix(storage): close the review findings on the KV + asset HTTP clients

Cross-review found the device-scope guarantee resting on its weakest layer,
and several places where the contract promised more than the code or the
conformance server could deliver.

deviceStore: the two type-level layers only documented intent — the barrier
that actually kept device values off the wire was the injected store, typed
as `KVStore`, which `HttpAccountKV` satisfies structurally (its methods are
the same methods minus an optional parameter). Injecting the transport as
the device backend type-checked and put device values on the network. The
device scope now requires a branded `LocalKVStore`, the transport declares
itself not to be one, and a runtime check refuses what a cast smuggles past.

resolve URLs: a media `src` carries cookies, never the client's headers
hook, so the proxied shape is only sound for cookie-authenticated
deployments — the contract now says so instead of claiming the content route
sits behind "the same authentication", and the conformance reader uses a
cookie rather than a header no browser could send. The client also validates
what it resolves: http(s) schemes only, and no `//host` or `/\host` slipping
through the relative branch to another origin.

Identifiers: refs and keys arrive percent-decoded, so `..%2F..%2F` was a
traversal waiting for the first backend to join it to a path. Both are now
constrained on both sides, and the contract states the MUST that keeps a
storage layer from being the first to look.

Also: the JSON gate runs before anything reads the value (a `JSON.stringify`
pre-flight ran caller code first and reclassified `{ toJSON: () => undefined }`
as a delete); scope routing fails closed; an upload's Content-Type can no
longer be relabelled by the headers hook; a mutation invalidates in-flight
resolution; unparseable 2xx bodies become typed errors rather than native
SyntaxErrors; signed tokens are validated rather than merely present; and the
contracts settle the per-principal claim model, the media-type allowlist, the
literal prefix rule, and the identifier charset that Part B would otherwise
have had to guess at.

* fix(storage): close the second review round on the KV + asset HTTP clients

The device-scope guard was in one place and needed to be in three. The
transport is exported and structurally a `KVStore`, so `kvPersistStorage(new
HttpAccountKV(...), 'device')` and a plain `KVStore`-typed reference both
compiled without a cast, dropped the scope argument on the floor, and put a
device value on the wire. The transport now takes the scope it was pretending
not to have — typed as `'account'`, refused at runtime for anything else, since
bivariant method parameters mean the type alone cannot hold — and the persist
adapter requires a `LocalKVStore` when paired with `'device'`.

The resolved-URL checks were text tests where only parsing works. The URL
parser strips ASCII tab, LF and CR before parsing, so `/<tab>/evil/x` walked
past the `//` prefix check and loaded cross-origin — in the app-mounted shape,
where a path-only base URL leaves that check as the only guard. The absolute
branch let through `https://` with no host and `https:host/x`, which names one
place standalone and another when a browser resolves it against a same-scheme
page. Both branches are now decided by the parser: control characters refused
outright, relative references validated against a probe origin, absolute ones
required to parse as `scheme://host` with an http(s) scheme — and still
returned byte-for-byte, so signatures survive.

The media-type MUST had no implementation and contradicted itself: the
conformance server stored and served `text/html` verbatim, and a metadata-less
upload became `application/octet-stream`, which cannot be on a renderable
allowlist. The server now implements the allowlist, serves everything else as
an opaque attachment, and the contract scopes its "usable as an img src"
promise to allowlisted types.

The KV key domain was HTTP-only, which made "the same suite proves the backends
equivalent" untrue: `a/b`, an empty key and a 600-byte key all passed in the
browser and would have become unreachable on a server. An audit of the app's
keys (learner key, storage generation, current-scene and migration markers,
persist names) found none in violation, so the rules are lifted to the
primitive and both backends enforce them, with the shared suite asserting it.

Also: the claim model the last round wrote into the contract is now implemented
and covered case by case; malformed percent-escapes are a 400 rather than a
500; the in-flight identity guard has a test that can fail; and the Content-Type
conflict raises a typed error.

* fix(storage): final review round — backend parity, URL probe, credentials

Four small things the final pass found, plus the contract patches Part B would
otherwise inherit.

The `toJSON` delete semantics were documented backwards. `BrowserKVStore.set`
was the trial-serialize the KV contract said no backend does, so
`{ toJSON: () => undefined }` was a silent delete there and a rejection over
HTTP — opposite answers to the same call. The browser backend now validates
scope and key before anything can run caller code, recognizes the delete case by
type, and refuses a value that still fails to serialize. Both cases are in the
shared suite, so the two backends cannot drift apart again.

The probe-origin check could not vouch for a URL naming the probe host itself:
`//asset-url-probe.invalid/x` resolves onto the probe origin and passed, then
resolves somewhere else entirely against a real base. Any authority-bearing
form is refused outright, so the check no longer depends on the probe host
being unguessable.

Cross-origin cookie deployments had no way to send a cookie: `fetch` omits
them cross-origin by default and the headers hook cannot help, since `Cookie`
is a forbidden header name. Both clients accept `credentials` and pass it to
`fetch`; the contract records the CORS obligations that come with it. Rather
than restricting cookie deployments to same-origin, which the asset contract
explicitly does not require.

The conformance server's dot-segment check was reading a path the URL parser
had already normalized, so `/assets/%2e%2e/x` arrived as `/x` and the documented
400 was really post-routing behaviour. It now validates the raw request target,
and the injected transport preserves it instead of handing over a normalized one.

Contract: the prefix rule names backslash (PostgreSQL's default LIKE escape,
and the one an implementer skips because a legal key cannot contain it, though
a prefix can), and acquiring a claim MUST leave the bytes present — a
de-duplicating server that inserts only the claim can race reclamation of the
last previous claim and leave a document resolving to a 404.

Also: base URLs are checked for an http(s) scheme at construction, the ref
domain moved next to the KV key domain and is enforced by both asset backends
with shared suite coverage, the KV client refuses a hook-supplied Content-Type
like the asset one, and CI runs the package typecheck that makes the
`@ts-expect-error` guards mean something.

* fix(storage): probe guard spelling, prefix validator, base url shape

Three one-line-level holes from the closing review.

The probe-host guard was spelled `startsWith('//')`, so the backslash forms
`/\host/x` and `/\/host/x` reached the origin comparison, passed it by naming
the probe host, and were stopped only by that host failing to resolve. It now
refuses any second character that can open an authority — which is also what
makes the comment true rather than aspirational: a path-absolute reference
always inherits the base's origin, so with no authority expressible the
comparison cannot be satisfied cross-origin, whatever the probe host is.

The conformance server validated `?prefix` with the path-segment validator,
rejecting `keys('.')` and `keys('..')` — legitimate prefixes of keys like
`.hidden`, which the client rightly allows. A prefix travels in the query
string and is never a path segment, so it now has its own validator: the key
rules minus the non-empty and dot-segment requirements. The contract says the
same, and the shared suite pins both backends to it.

Base URL validation moved into one shared helper both clients call, since two
copies of a security rule is how they drift. It now also refuses
`https:host/path` — which parses standalone to that host but is resolved
against the current document by `fetch`, sending requests and their credentials
somewhere the operator never wrote — and a base carrying a query or fragment,
which silently swallows the path concatenated onto it.

* fix(storage): close two holes in the shared base-url check

The path-only branch returned its input unexamined, so `//evil.example` and
`/\evil.example` were accepted as paths. A browser reads both as an authority,
which means every request built on such a base — and every credential the
headers hook attaches — leaves the origin. A base is now required to be a
single `/` followed by something that is not `/` or `\`, the same refusal the
resolved-URL check already makes, for the same reason. Control characters are
refused first: the parser strips or re-encodes them, and `/<tab>/evil.example`
becomes `//evil.example` after it does.

The query/fragment check read the parsed `search` and `hash`, which are empty
strings for a base ending in a bare `?` or `#` — so exactly the inputs that
swallow the concatenated path into a query or fragment were the ones that got
through. It reads the raw string now, which also makes the post-parse check
redundant rather than merely unreachable.

* fix(storage): bypass HTTP caches on reads, and require a 404 for not-found

Two mechanisms the clients were missing, on both sides.

Reads are marked `cache: 'no-store'`. The asset resolve request answers two
mutable questions — does this principal hold a claim, and which URL is valid
now — so a cached answer returns an expired signed URL or replays a negatively
cached 404 for an asset written since; the in-flight coalescing that would
otherwise cover this lives in the client and cannot reach the HTTP cache layer.
KV reads have the same problem for a different reason: `account` is by
definition the scope another device may have just written, and nothing here can
invalidate a cached copy when it does. The contracts now require `no-store` on
those responses. Asset content is left cacheable — bytes at a content-addressed
ref never change — and writes are unmarked, having nothing to read from a cache.

The not-found mappings now require the status as well as the code. A proxy or
gateway answering 401, 403 or 500 while echoing the body's error code was being
read as "this does not exist", and `null` is indistinguishable from a real
miss — so an outage reached the caller as data loss.

* fix(storage): reject unusable base urls, and make the harness meet the contract

Two configuration checks and two harness gaps.

A base URL carrying userinfo built a client that threw a native TypeError on
every operation, because Fetch refuses to construct a request from a URL with
embedded credentials — one legible error where the deployment is configured
beats a per-call failure with no explanation. A base with surrounding
whitespace was worse than useless: `new URL` strips it, so validation passed,
and then concatenation moved the space inside the URL where it is no longer
trailing and no longer stripped, breaking every request.

The conformance server now sends `Cache-Control: no-store` on the three reads
the contracts require it on. The requirement landed last round with nothing
asserting it, so the suite would have passed against exactly the implementation
it exists to catch. And `DELETE /kv/entries/{key}` refuses a request body
outright: the query and the header were already checked for a smuggled scope,
leaving the body as the one channel through which a delete could still describe
one.

* fix(storage): allow a device-routing composite to persist device-scoped state

cosarah found kvPersistStorage(httpKVStore, "device") wrongly rejected. An
HttpKVStore is a full dual-scope composite: it routes device operations to the
LocalKVStore it requires at construction and only reaches the network for
account, so device values never leave the machine. The guard tested
isLocalKVStore — "is the whole store local" — and so turned away a store that
is safe for device precisely because it is not fully local.

The guard now turns on the capability that actually matters: does the device
scope stay local. A new DeviceSafeKVStore brand (servesDeviceScopeLocally: true)
marks a store whose device writes never leave the device — held by a fully-local
LocalKVStore (which extends it) and by HttpKVStore, and declared false by
HttpAccountKV, the pure account transport with no local device backend. The
persist device overload requires DeviceSafeKVStore; the account overload is
unchanged.

The security boundary the red team opened this whole line on is untouched:
HttpAccountKV used for device is still doubly refused — its false brand is not
assignable to the true DeviceSafeKVStore requires (type), and the runtime check
rejects the cast that would erase it. The brand is structurally unforgeable, not
a flag the transport could set; and the injected device backend of a composite
still demands the stronger, fully-local LocalKVStore, so composites cannot nest
into a router loop with no local floor.

Regression test (cosarah's ask): kvPersistStorage(httpKVStore, "device")
set/get/remove reach the injected device backend, land device-scoped there, and
make zero HTTP requests. Mutation-checked: widening the brand so HttpAccountKV
is accepted, or neutering the guard, turns the device-out reject test red.

* refactor(storage): scope #1002 down to KV — remove the asset HTTP backend

Per the maintainer decision, the AssetProvider server design moves to the
global-resource-pool RFC (#1007), where AssetRef changes from content-addressed
to an allocated global id and the contract model itself changes. Continuing to
harden the content-addressed asset client here would be work on code that is
being replaced, so the asset half of #1002 is withdrawn and the PR is pure KV.

Removed (all introduced by #1002):
- docs/asset-http-contract.md
- src/asset/http.ts (HttpAssetProvider) and its index / package.json exports
- src/asset/content-ref.ts (assertAssetRef / computeAssetRef / the ref shape)
- test/http-asset-provider.test.ts and the asset half of the conformance server

Reverted to the #858 baseline, untouched:
- src/asset/browser.ts — back to opaque resolve/remove, no assertAssetRef guard.
  This directly removes cosarah's latest asset finding: an opaque ref such as
  `bucket/path` no longer throws, restoring the DSL AssetRef-opaque contract.
- test/asset-contract.ts, test/asset-browser.test.ts — 0-diff from origin/main.

Kept (all KV): kv-http-contract.md, src/kv/* (HttpKVStore / HttpAccountKV /
the DeviceSafeKVStore brand), the KV tests, and the KV conformance server —
renamed kv-conformance-server.ts and reduced to KV routing over the shared
harness framework (body caps, no-store, scope-channel and dot-segment guards,
auth hooks). base-url.ts stays; KV still uses it.

* fix(storage): treat KV keys as opaque; document account-sync prerequisites

cosarah found the key validation we added for traversal defense breaks
legitimate callers: DSL identifiers (stageId/sceneId/learnerKey) are
unconstrained strings — verified, the DSL only requires typeof === 'string' —
and app callers compose keys like `editor-current-scene:<stageId>`, so a valid
stage id `stage/one` now throws in BrowserKVStore before localStorage.

Fix, matching the asset-opaque precedent: a KV key is an opaque string again.
The `/` and `\` rejection is removed from assertKVKey / assertKVKeyPrefix and
from the conformance server. Traversal is defended by encoding, not rejection —
the HTTP client already percent-encodes the whole key into one path segment, so
a separator never opens a new segment on the wire, and the server stores the
decoded key as a plain map key (bound value), never a path. `a%2F..%2F..%2Fb`
decodes to the single opaque key `a/../../b`, which addresses one entry and
traverses nothing; a raw unencoded `..` path produces extra segments that match
no route (404). The rules that remain are only what encoding cannot cover and
the transport cannot carry (empty, whole-key `.`/`..`, NUL, lone surrogate,
length) — none producible by `prefix + id`.

Tests: the shared suite now round-trips keys with `/`, `\`, `%`, `:`, spaces
across both backends; a `stage/one` key round-trips through the real conformance
server; the traversal input is proven to store as one opaque key and the raw
path to 404. Mutation-checked: re-adding the `/` rejection reddens exactly the
round-trip cases.

Docs (kv-http-contract.md):
- "A key is an opaque string" replaces the identifier-shape section — keys may
  contain separators; traversal is an encoding + server-bound-value duty.
- Account settings sync now documents its security prerequisite next to the
  account scope: a deployment MUST provide real per-user isolation of stored
  rows and encryption at rest before enabling sync; the reference server is not
  that posture.
- kvPersistStorage(device) doc corrected from LocalKVStore to DeviceSafeKVStore
  (the device-safe brand accepts the HttpKVStore composite; HttpAccountKV stays
  double-rejected).

* fix(storage): close the scope/key/prefix contract gaps with a coverage matrix

Three completeness gaps, nailed by an executable matrix so an untested
channel/shape can't slip through the next pass rather than patched one by one.

1. Scope via a GET body was not rejected. `assertNoScopeChannel` covered the
   query and header, but the bodyless GET routes never read their body, so
   `GET /kv/keys` with `{"scope":"device"}` returned 200 []. Bodyless methods
   (GET, DELETE) now reject any request body up front — that is the channel a
   scope would hide in — and only `set` reads a body, checking it for a scope
   field. The DELETE route's own body check folds into the shared one.

2. The 512-byte key bound wrongly rejected legitimate keys. A DSL id is an
   unconstrained string (verified: the DSL requires only typeof === 'string'),
   and `editor-current-scene:` + a 500-char stage id is 521 bytes, which
   BrowserKVStore rejected before localStorage. Keys are length-unconstrained;
   the bound is raised to a generous 8 KiB DoS ceiling and documented as a
   resource guard, not part of the key domain — not a derived/hashed key, which
   would break the literal-prefix semantics of keys(prefix). Both backends and
   the conformance server move in lockstep.

3. The prefix contract text contradicted itself: it claimed a legal key can
   never contain a backslash, while the key section (correctly) makes keys
   opaque, backslash included. Reworded — a prefix is opaque like a key — and
   the shared literal-prefix matrix now covers `\` (PostgreSQL's LIKE escape),
   which it had skipped, alongside `%`, `_`, and combinations.

Coverage matrix (CI-executable):
- scope-rejection: {get,set,remove,keys} × {query,header,body}. query/header
  run in-process; the body cells use a raw HTTP client (fetch cannot put a body
  on a GET — exactly the non-conforming client the finding described) against a
  loopback listener, skipped where the sandbox forbids binding.
- key-validity: `/ \ % _ : .` space, BMP + astral Unicode, `%2F`, a 500-char
  composed key, and all-at-once — each round-trips (set/get, keys(prefix)
  match, remove) on both browser and HTTP backends via the shared suite.
- prefix-charset: `%`, `_`, `\`, and combinations match literally, both backends.
- Boundaries still rejected: whole-key `.`/`..`, NUL, lone surrogate, empty,
  and the DoS ceiling.

Mutation-checked: removing the bodyless-body rejection reddens the three GET/
DELETE body cells; lowering the ceiling back to 512 reddens the long-key
round-trip on both backends.

Bumps @openmaic/storage to 0.1.2 (src/kv/* changed).

* fix(storage): bound the KV key DoS ceiling by encoded size, not UTF-8 bytes

Follow-up to the 8 KiB ceiling: measuring it in UTF-8 bytes ignored
percent-encoding expansion and reopened a backend-parity break. A non-ASCII key
is small in bytes but large on the wire — `€` is 3 UTF-8 bytes and `%E2%82%AC`,
9, encoded — so `'€'.repeat(2730)` (8190 bytes, under the old cap) encoded to
~24.6 KB, which the Node HTTP server rejects with 431 before routing while
`BrowserKVStore`, which never builds a URL, accepted it.

The ceiling is now measured on `encodeURIComponent(key).length` — the size the
key occupies as a request target — at 4096, far above any real id (a 500-char id
under `editor-current-scene:` encodes to ~523) and well below Node's default
16 KiB `maxHeaderSize` (empirically the 431 trigger on Node 22), so no key that
passes validation can reach a 431. Both backends and the conformance server use
the same encoded-size limit, so a key is accepted iff its encoded form fits,
whichever backend it reaches — parity restored. `MAX_KV_KEY_BYTES` becomes
`MAX_KV_KEY_ENCODED_LENGTH`.

Tests, against a real node:http server for the 431 boundary:
- the max-legal non-ASCII key (455×€, encoded 4095) round-trips over real HTTP
  with no 431, and the browser accepts the same key — parity on accept;
- one code point over (456×€, encoded 4104) is rejected by both backends at
  validation, before any request — the exact parity case a byte bound missed
  (1368 bytes, would have passed, then 431'd over HTTP);
- a raw client bypassing client validation with an over-ceiling (under 16 KiB)
  encoded key gets a clean 400, not a 431.
Shared suite's key-domain matrix now bounds by encoded size on both backends.

Mutation-checked: reverting the ceiling to UTF-8 bytes reddens the three
encoded-length parity tests. Bumps @openmaic/storage to 0.1.3 (src/kv/* changed).

* fix(storage): make the KV key domain truly opaque; keep transport limits out

The recurring key-limit findings (512 → 8 KiB → 4096, each patch exposing the
next) shared one root cause: transport-driven rules kept being added to the key
domain — the browser primitive included — breaking the "opaque unconstrained
string key" contract. This is the structural fix, per cosarah: "keep HTTP
transport limits out of the browser primitive and preserve the existing string
key domain."

Approach (a), the minimal one: a KV key is any string, validated nowhere. The
browser primitive is a Map/Storage that stores any key; the HTTP backend carries
the key as a URL path segment and inherits that transport's limits, documented
as HTTP-deployment concerns that never constrain the key domain. Every real key
(a `prefix:id` from an unconstrained DSL string) round-trips on both backends;
only pathological keys hit a transport limit, and none of those are keys a caller
produces. (b) — keys in the request body for accept-parity — was unnecessary:
verified that no real key needs it.

Removed from the key domain (browser + HTTP + conformance server):
- the encoded-size / length ceiling entirely — there is no key-length limit;
- the NUL exclusion — NUL percent-encodes to %00, is preserved end to end, and
  is a legitimate Map/Storage key (a false "cannot represent" premise);
- the `.`/`..`/empty/`/`/`\` rejections — all opaque, all round-trip.
`assertKVKey` / `assertKVKeyPrefix` / `MAX_KV_KEY_*` are gone.

Kept, at the transport layer only (HttpAccountKV), never reaching the primitive:
- an unpaired UTF-16 surrogate genuinely has no percent-encoding, so the HTTP
  client surfaces a clear transport error (KEY_NOT_ENCODABLE) while the browser
  stores the same key — verified: encodeURIComponent throws on it.

Scope completeness (P2): the "reject scope in every channel" guarantee had two
holes — a scope path segment (`/kv/device/keys`) 404'd instead of 400, and only
`x-scope` was checked among header spellings. The server now rejects a scope
path segment and the whole prohibited header set (scope, x-scope, kv-scope,
x-kv-scope). The coverage matrix is {get,set,remove,keys} × {path, query, each
header spelling, body}.

Coverage matrix reworked to verify arbitrary opaque keys (empty, NUL, control
chars, separators, long, Unicode) round-trip on both backends — not to verify a
limit. A real node:http test proves NUL and long keys round-trip end to end, and
that a lone surrogate is a transport limit (browser accepts, HTTP client errors).
Mutation-checked: re-adding a NUL rejection, removing the path-segment check, or
dropping a header spelling each reddens the matching cells.

Cleanup: package.json description updated (KV HTTP delivered, not "later");
network-server bind/skip/close lifecycle deduped into one helper. Bumps
@openmaic/storage to 0.1.4 (src/kv/* changed).

* fix(storage): reject whole-key "."/".." in the HTTP client — they alias entries

Follow-up to making the key domain opaque: removing the `.`/`..` key-domain
rejection was right (the browser stores them fine), but the HTTP client then let
them reach `fetch`, where URL path normalization silently rewrites the target
before it is sent. `encodeURIComponent('.')` is `.`, so `/kv/entries/.` collapses
to `/kv/entries/` (the empty key) and `/kv/entries/..` walks up a level — so
`get`/`set`/`remove` on a whole-key `.` or `..` silently read, overwrite, or
delete a *different* entry, with no error. A data-correctness bug.

Fix, same pattern as the unpaired-surrogate limit already handled: a whole-key
`.`/`..` is something the URL-path transport structurally cannot carry, so the
client's path-segment encoder refuses it with `KEY_NOT_ENCODABLE` before a
request is built. Split the encoder in two: `encodeKeyPathSegment` (key → path
segment, rejects whole-key `.`/`..`) and `encodeComponent` (the `keys()` prefix →
query value, where `.`/`..` are legitimate and untouched). A key that merely
*contains* a dot (`a.b`, `prefix:id`) is unaffected and round-trips. The browser
primitive still stores `.`/`..` opaquely.

The HTTP transport's limits are now complete — three cases, all fail-loud at the
transport layer, all storable on the browser: (1) an unpaired surrogate (no
percent-encoding), (2) a whole-key `.`/`..` (URL normalization aliases it), and
(3) an over-long key (deployment request-target ceiling). The contract lists all
three as HTTP-deployment limits, not key-domain constraints.

Tests: whole-key `.`/`..` — browser stores and round-trips (distinct from the
empty key); HTTP client throws `KEY_NOT_ENCODABLE` and builds no request; and a
real-server test asserts the empty-key entry is never read, overwritten, or
deleted by a `.`/`..` operation. A dot-containing key (`a.b`) round-trips.
Mutation-checked: dropping the whole-key check reddens the alias tests.

Bumps @openmaic/storage to 0.1.5 (src/kv/* changed).

* fix(storage): reconcile the settings/profile persist consumer with the KV API

The integration merge (#1002 KV into main) surfaced two things the merge itself
could not resolve mechanically:

- `lib/store/kv-persist.ts` (added on main by #1001) called
  `kvPersistStorage(kv, scope)` with a *variable* scope, which #1002's overloads
  deliberately reject — `'device'` must be paired with a device-safe store, so
  the overloads take the scope as a literal. Branch on the scope: `'account'`
  takes any `KVStore`; `'device'` narrows the backend to `DeviceSafeKVStore` via
  its brand (the adapter re-checks at runtime) and otherwise fails loud. The app
  wires only `'account'` today; the `'device'` arm keeps the generic helper
  honest. `ControllableKV` in the persist test wraps a local `BrowserKVStore`,
  so it is genuinely device-safe and now declares the brand.

- `packages/@openmaic/storage` version bumped 0.1.5 → 0.1.6: the merge changed
  storage inputs (README + a pg-schema test carried from main) relative to the
  previous integration tip, so the version-bump guard requires an increase above
  #1002's 0.1.5. Still ahead of main's 0.1.1.

Verified: root `tsc --noEmit` clean, the persist test green (40 passed), and the
storage package suite green on Node 22.

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.

* 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.

wyucandClaude Opus 5 97f8585728 refactor(pbl-v2): route runtime agents through the shared LLM entry point (#1006)
* refactor(pbl-v2): route runtime agents through the shared LLM entry point

The five PBL v2 runtime call sites (instructor x2, evaluator, simulator x2)
invoked the AI SDK directly while the other 21 call sites in lib/ and app/ go
through callLLM / streamLLM, so they silently opted out of everything the shared
entry point applies:

- Usage accounting. recordUsage is reached only from the wrappers, so no
  instructor turn, evaluator pass, simulator line or narrator pass was ever
  accounted for - the highest-frequency, longest-context LLM traffic in the
  product. The comment at llm.ts:275, that every server-side call funnels
  through the wrappers, did not hold.
- The LLM_THINKING_DISABLED kill switch, read inside the wrappers only.
- One thinking resolution path. runtime-thinking.ts existed precisely because
  the agents bypassed the wrapper, and it was wired into instructor (x2) and
  evaluator but neither simulator site.

Also fix callLLM recording result.usage, which on a multi-step tool run
(stopWhen) is the final step alone; totalUsage is the aggregate, and the
instructor turn is exactly such a run. streamLLM already preferred the
aggregate.

Thinking semantics are preserved per call site: the teaching turns keep
force-disabling thinking, now through the wrapper's own `thinking` argument,
and keep their existing providerOptions spread, which injectProviderOptions
yields to; the simulator keeps honouring a per-request config, as before. The
one behavioural difference is on native adapters when no thinking config
arrives: the policy now resolves to an explicit lowest/disabled provider option
instead of leaving the model's default in place - which is what the policy
always claimed to do, and what OpenAI-compatible providers already got.
Unifying the wider divergence is a product decision and stays out of scope;
runtime-thinking.ts now documents it, along with the fact that the original
tool_choice justification no longer matches the tree.

A lint guard restricts importing generateText / streamText to lib/ai/llm.ts so
the split cannot grow back. It uses the @typescript-eslint variant of
no-restricted-imports deliberately: flat config replaces a rule's options per
key rather than merging them, and the base rule is already configured for the
lib/choreography and lib/video-export module boundaries.

The runtime-thinking test moves from asserting the retired helper to asserting
what the call site is responsible for, at the provider boundary: an evaluator
turn reaches the provider with a disabled config in the thinking store, does
not leak it, and is accounted for under its own usage source.

Closes #1003

* fix(pbl-v2): address cross-review findings on the shared-entry migration

Consensus findings from an independent cross-vendor review of cc48ada.

callLLM recorded usage only after validation passed, so with `retries > 0`
every attempt that failed validation went unaccounted, and a result handed back
after the retries were exhausted recorded nothing at all. Each attempt that
reaches that point was billed, so record before validating. Latent today (no
caller passes retryOptions) but it sits in the function this PR already touches.

The simulator's character line now hands its incoming thinking config to
streamLLM instead of resolving providerOptions by hand. The hand-rolled call
covered native adapters only, so a stage-route thinking config was silently
dropped on OpenAI-compatible providers - the wrapper also seeds the thinking
context that their fetch wrapper reads. Native adapters resolve identically:
both paths end in the same normalizeProviderId + buildThinkingProviderOptions.

runtime-thinking.ts documents two things the previous docstring implied away.
On native adapters the constant is a no-op whenever a thinking config does
arrive, because the teaching turns pass their own providerOptions and
injectProviderOptions yields to a caller-set value. And "disabled" is resolved
against each model's catalogued capability, which for some models is not off:
measured against the current catalog, gpt-5.4-pro resolves to effort medium,
gemini-2.5-pro to thinkingBudget -1 (dynamic thinking) and claude-fable-5 to
adaptive/low. Those match the model's own default today, so behaviour is
unchanged, but the policy is weaker than its name suggests.

Tests cover both accounting paths (a retried attempt and an all-attempts-failed
run each record every attempt), and the defensive totalUsage fallback is now
labelled as defensive - ai@6 always reports the aggregate.

The lint guard's scope comment also notes namespace imports, which importNames
cannot see.

* fix(pbl-v2): correct the thinking-policy rationale; stop tests writing the real usage log

Two things, both prompted by probing the live DeepSeek API with the instructing
turn's exact shape rather than reasoning from the tree.

The docstring in runtime-thinking.ts claimed the policy's original justification
had expired, on the grounds that `begin_turn` and the forced `tool_choice` it
used are gone. That reads as an invitation to delete the force-disable, and it
is wrong. Measured against DeepSeek V4 Pro:

  thinking on + tools + stopWhen  -> streams fine, 66 reasoning tokens
  thinking on + forced toolChoice -> still 400, "Thinking mode does not
                                     support this tool_choice"

The incompatibility is bound to a FORCED tool choice, not to tools in general.
Today's turns do not reach it, but anyone who reintroduces a forced tool choice
will, so the policy is a live guard rather than dead weight. It also buys
latency: the same probe reached its first token in 1.4s with thinking off
against 3.0s with DeepSeek's default thinking on, and the teaching turns gain
nothing from thinking while the instructor is the chattiest surface in the
product. The docstring now records the measurements instead of the guess.

Separately: a test run could append to the app's real usage log. Any test that
exercises callLLM / streamLLM reaches `recordUsage` through `recordUsageSafe`
without asking for it, so rows sourced `minimax-auth-test`,
`minimax-thinking-test`, `minimax-fixed-thinking-test` and `serialization-test`
were sitting in the live `data/usage/` file next to production traffic
(tests/ai/minimax-provider.test.ts:58,101,146 and
tests/ai/anthropic-serialization.test.ts:38 — neither predates this PR).
`recordUsage` now returns early under vitest unless the caller asked for a
specific `baseDir`, which is the fix at the boundary rather than in the two
tests that happened to trip it. Storage tests pass an explicit `baseDir` and
tests that assert accounting mock the module, so both keep working; verified by
running all three files and confirming the live file's line count is unchanged.

* refactor(pbl-v2): drop the hardcoded thinking policy, finishing the unification

The point of this PR is that the PBL v2 runtime reaches the model the same way
everything else does. Keeping a hardcoded `PBL_V2_TEACHING_THINKING` override
inside the agents worked against that: the teaching turns still resolved
thinking through a second, private path, and it produced the awkward edges this
PR had to disclose — an override that silently loses to a caller-set
`providerOptions` on native adapters, and a "disabled" that resolves to
`effort: medium` or `thinkingBudget: -1` (dynamic thinking) on models whose
catalogued capability has no off value.

So the policy is gone. All five sites now pass the incoming request / stage-route
config straight to `streamLLM` / `callLLM`, which is the one place that resolves
provider options and seeds the thinking context. `runtime-thinking.ts` is
deleted, and the hand-rolled `resolveThinkingProviderOptions` calls with it.

What justified keeping it, and why that was not enough:

- The DeepSeek 400 is real — probed live, thinking on + a FORCED `toolChoice`
  still fails with "Thinking mode does not support this tool_choice" — but no
  call site in the tree forces a tool choice, so the policy was guarding a
  scenario that does not exist, at the cost of the entry-point unification. The
  hazard is now a comment where a forced tool choice would be introduced, which
  is where a future author will actually look.
- Thinking costs latency on the teaching turns (~1.4s to ~3.0s first token on a
  thinking-by-default model, measured on DeepSeek V4 Pro). That is a real cost
  but a deployment preference, and it belongs in the `pbl-v2-runtime` stage
  route, not hardcoded in the agent where it overrides whatever that route says.
  Noted at the instructor call site with the numbers.

Behaviour change to be aware of: on OpenAI-compatible providers the teaching
turns no longer force thinking off, so a thinking-by-default model now thinks
unless the route says otherwise — slower first token and reasoning tokens on the
bill. Pin `thinking` off on the stage route to keep the old behaviour.

The runtime-thinking test becomes runtime-llm-entry and asserts the new
invariant at the provider boundary: an incoming config arrives intact, NO config
means no config (a re-added constant would fail this), the global kill switch
still applies, nothing leaks, and the turn is accounted for.

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

* fix(pbl-v2): forward the resolved thinking config to the simulator narrator

Review finding from @cosarah on #1006, and a correct one: the director-narrator
pass was the last site still dropping the resolved config. Both callers passed
`thinkingConfig` into `runDirectorNarratorPass`, but the helper never destructured
it and never handed it to `callLLM`, so the provider silently fell back to the
model default instead of honouring the `pbl-v2-runtime:simulator` route.

Earlier revisions of this PR documented that as pre-existing and deliberately
untouched. That defence stopped holding once the hardcoded thinking policy was
deleted: the PR's invariant became "every PBL v2 site resolves thinking through
the shared entry point, and the deployment decides", and the narrator was the one
site contradicting it.

Coverage per the review: the simulator turn is now driven end to end against a
scenario fixture, asserting that BOTH provider calls — the streamed character
line and the non-streamed narrator pass — see the incoming config, that neither
substitutes one when the request carries none, and that both are accounted for
under their own usage sources. The `['generate','stream']` assertion keeps the
test from silently covering only one of the two calls.

Fault-injected to confirm it bites: dropping the new fourth argument again turns
"forwards an incoming config to the character line AND the narrator" red.

* fix(lint): close the dynamic-import bypass on the LLM entry-point guard

Second review pass from @cosarah on #1006. He is right that the guard was not
airtight, though the picture turned out narrower than described — I checked each
form against eslint instead of reasoning about it:

  import { streamText } from 'ai'   already blocked
  import * as ai from 'ai'          already blocked (ESLint reports a namespace
                                    import when importNames is set)
  require('ai')                     already blocked, by the repo-wide
                                    @typescript-eslint/no-require-imports
  await import('ai')                NOT blocked  <- the real hole
  await import(`ai`)                NOT blocked

So the dynamic form is now covered by a no-restricted-syntax block, in both the
literal and template-literal shapes. That rule key is configured by five earlier
blocks and flat config replaces options per key rather than merging them, so the
new block explicitly ignores those directories rather than silently dropping
their module boundaries. It costs nothing: lib/choreography and lib/video-export
already allowlist their import sources (importing 'ai' there is an error today,
and video-export bans ImportExpression and require outright), and the two
@openmaic packages are built in isolation against @openmaic/dsl with the SDK
nowhere in their dependency graph.

The comment above the guard claimed namespace imports were out of scope because
importNames cannot see them. That was wrong; it now lists what each form is
caught by, and notes that an eslint-disable still defeats all of it — which is
the point, since the bypass then has to be written down where a reviewer sees it.

Verified with a probe file using all five shapes: five errors, one per line.
Injecting `import 'react'` plus an `'ai'` import into lib/choreography still
fails on both pre-existing boundary rules, confirming no clobbering.

Also updates the PR description, which still described the narrator as ignoring
its thinking config — stale since 9bbb720.

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

* fix(lint): cover the @openmaic packages with the dynamic-import ban

Third review pass from @cosarah on #1006, and he is right again: the guard
ignored packages/@openmaic/renderer and packages/@openmaic/storage, and
`void import('ai')` under the renderer source path passed lint. Reproduced before
fixing.

The previous revision justified those two exclusions by arguing the packages are
built in isolation against @openmaic/dsl with the SDK nowhere in their dependency
graph. That is an argument about why a bypass would not matter, not a rule that
stops one — exactly the kind of reasoning this PR exists to replace with
enforcement.

The two selectors are now a shared AI_SDK_DYNAMIC_IMPORT_BAN spread into both
package blocks, rather than dropping those directories from the repo-wide block's
ignores: they configure no-restricted-syntax for their own `@/` boundary, and
flat config replaces rule options per key, so matching their files would have
silently deleted that boundary.

lib/choreography and lib/video-export stay ignored and stay covered — their
blocks ban EVERY ImportExpression outright, which subsumes this one. That claim is
now checked rather than asserted.

Verified with a `void import('ai')` probe in six production paths — both
@openmaic packages, choreography, video-export, lib/pbl, app/api — one error
each; lib/ai/llm.ts and tests/ stay clean; and an `@/lib/foo` import under the
renderer still fails its own host-path boundary, confirming no clobbering.

Also rewrites the PR description's e2e section, which still described the deleted
thinking policy. The browser run predates that deletion, so its streaming and
accounting evidence stands (the wrapper path is unchanged) but its thinking
observations do not. Replaced with a fresh live probe of the final behaviour: with
no route thinking the instructing turn reports 60 reasoning tokens, with `thinking`
pinned off on the stage route it reports 0.

* fix(lint): guard every source extension, and pin the coverage matrix in a test

Fourth review pass from @cosarah on #1006. Confirmed before fixing: an
`app/api/**/route.js` containing both a named and a dynamic `'ai'` import passed
lint with exit code 0, because both guard blocks matched only `**/*.{ts,tsx}`
while every module-boundary block in the same file matches
`**/*.{ts,tsx,js,jsx,mjs,cjs}`. Both blocks now match the same set. The repo has
real `.mjs` under scripts/, so this was not hypothetical.

That is the third scope hole review has found in this guard — two @openmaic
package directories, then the extension list — and each one was closed and then
verified by hand, which is the process that produced the next one. So the matrix
is now an executable contract: tests/lint-llm-entry-guard.test.ts runs the real
eslint against the real config over every import form (named, namespace, dynamic,
dynamic-template) × every source extension × nine production paths, asserts the
three deliberate exemptions still pass, and asserts the module boundaries that
share the `no-restricted-syntax` key still fire. A future edit that narrows
`files`, adds an `ignores` entry or swaps the rule key fails CI instead of
quietly reopening the door.

Fault-injected against both earlier findings to prove it bites: narrowing the
scope back to ts/tsx turns the js/jsx/mjs/cjs rows red, and re-adding the two
@openmaic packages to `ignores` turns the dynamic-import rows red. It also treats
an eslint-ignored path as "not covered", so a path that silently stops being
linted cannot masquerade as a pass.

杨慎andClaude Opus 4.8 6d29241bb0 feat(video-export): fidelity polish — spotlight geometry, video clips, formulas, subtitles (#952)
* fix(video-export): bridge play_video element id → media ref

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

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

Refs #867.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

- geometry: don't feed the measured content-box AABB to a rotated video clip —
  it already encloses the rotation, so re-applying `rotate` doubled it. Rotated
  elements fall back to the authored box (one, un-doubled source of truth).
- build-export-zip: extract shared `compileStageIr` so buildExportZip and
  compileSubtitles can't drift on the timing/assets/geometry wiring.
- split-cue: join merged CJK cue pieces without a spurious ASCII space.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

b4e3145c90 feat(roster): single-source the generated agent roster on the stage document (#994)
* feat(roster): single-source the generated agent roster on the stage document

The generated agent roster used to live in two places at once: the stage
document carried generatedAgentConfigs, while a per-stage IndexedDB mirror
(db.generatedAgents) was the actual read authority — and the only home of
each agent's voice binding. The split caused real losses: voices vanished on
device switches, exports, and shares (the mirror never travels), the load
path trusted a device-local table over the portable document, and roster
edits persisted through a bespoke debounce with no beforeunload flush.

Make the stage document the single source of truth:

- Contract: add optional voiceConfig/voiceDesign to GeneratedAgentConfig in
  @openmaic/dsl (VoiceDesign moves into the contract; the app re-exports it).
  Additive optional fields — not a breaking serialized-shape change, so
  DSL_VERSION stays put per the version policy.
- Writes: remove every mirror writer (registry saveGeneratedAgents, the
  stage store's debouncedSaveAgents bypass, classroom-load hydration, import
  direct writes). setStageAgents now only marks the stage dirty for the
  shared persistence scheduler plus synchronous in-memory registry/selection
  mirrors; generation and import embed the roster on the stage.
- Reads: classroom load hydrates the registry from the loaded stage's
  generatedAgentConfigs; export reads the stage roster directly.
- Lazy migration: the mirror is retained read-only. On load, a roster (or
  voice fields) missing from the document is backfilled from the mirror,
  committed onto the in-memory stage, and persisted by the next flush —
  idempotent, and gated on the current stage id after every await so a
  classroom switch cannot leak a stale roster into the registry.
- Deletion: deleteStageData discards the deleted stage's pending
  persistence work so a queued flush cannot resurrect the document.
- Round trip: classroom ZIP manifests now carry the voice fields, so
  export/import preserves agent voices.

* fix(roster): harden deletion, migration, selection, and ingress paths

Review hardening on top of the roster single-source change:

- Deletion vs in-flight persistence: deleting a stage now registers a
  session-scoped tombstone (lib/utils/deleted-stages.ts) before the cascade
  starts. Every persistence landing point checks it — the scheduled flush and
  the departing-stage retry drop their snapshots, and the aggregate/incremental
  saves re-check under the document lock, including the incremental path's
  full-save fallback that would otherwise rebuild a deleted document from the
  in-memory snapshot. A deletion that fails before the document is removed
  lifts the tombstone so the still-existing stage keeps persisting.
- Lazy migration termination: a fruitless legacy-mirror probe (nothing to
  merge — e.g. server-generated rosters, which are voiceless by design) is
  remembered per stage for the session instead of re-querying the mirror on
  every load forever. Successful merges are not memoized so a failed flush is
  retried on the next load. Docstrings now state the real lifecycle.
- Selection provenance: setStageAgents no longer overwrites a user-set agent
  selection with the full roster. Stage-derived selections still track the
  roster; a user-set auto selection is only narrowed to surviving agents
  (newcomers are not auto-selected, the user-set flag is untouched), and a
  user-set preset selection is left alone — matching restoreAgentSelection.
- Mirror hygiene: deleteStageData clears the deleted stage's rows from the
  legacy roster mirror (best-effort), and the mirror table's docs now describe
  its actual access pattern (migration reads + deletion hygiene).
- Registry persistence: the agent registry's persist snapshot partializes
  generated agents out of localStorage, making the stage document the roster's
  only durable home; the rehydration merge filter remains as defense in depth.
- Ingress validation: imported manifest voice fields are structurally
  validated (malformed bindings dropped per field, the agent survives), and
  applyGeneratedAgentsToRegistry validates providerId against the known TTS
  provider registry instead of casting, treating unknown providers as "no
  bound voice".
- Contract: drop the speculative AgentVoiceConfig.modelId — an audit of every
  roster producer, current and historical, found none that ever emitted it.
  Contract fields are added once a producer exists, not before.

New tests cover the deletion tombstone at both the store and storage layers
(including the missing-destination full-save pin and the lock-race re-check),
the fruitless-probe memo, the selection-provenance matrix, persistence
exclusion of generated agents, and voice-field sanitization on import.

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

* fix(roster): close tombstone lifecycle, probe-memo, and selection-intent gaps

Second hardening pass over the deletion/migration/selection fixes:

- Tombstone lifecycle: a deleted classroom id can legitimately come back
  (deletion is client-side only). Explicit (re)creation points now lift the
  tombstone — server-copy restore in applyClassroomStageAndScenes and backup
  restore in importDatabase — so edits after a same-session restore persist
  again, while in-flight flushes stay fenced.
- Failed deletion now restores the dirt it discarded: deleteStageData
  snapshots the pending map plus the in-flight round before tombstoning, and
  re-marks it when the delete fails with the document still present.
- Legacy-mirror probe memo now distinguishes a FAILED read (null, retried on
  the next load) from a confirmed-empty mirror (memoized), so a transient
  IndexedDB error cannot suppress migration for the whole session.
- Incremental save tail (currentScene KV row + chat sessions) is tombstone-
  fenced like the aggregate path, and both paths re-check the tombstone
  immediately before every write, with comments scoped honestly for the
  lock-free (no Web Locks) best-effort LWW fallback.
- Roster-edit selection mirror: an empty intersection now falls back to the
  full roster and clears the user-set flag (matching restoreAgentSelection's
  length > 0 gate), and a user-set selection that equals the pre-edit full
  roster keeps tracking the roster wholesale so newcomers are not excluded
  forever by the AgentBar auto-toggle snapshot.
- TTS/ASR provider lookups use Object.hasOwn instead of `in`/bare indexing,
  so prototype-chain keys ('toString', 'constructor', ...) no longer pass the
  provider whitelist or resolve to Object.prototype members.
- Documented the per-tab limit of the tombstone set.

* fix(roster): replace the boolean deletion tombstone with a deletion-generation model

A boolean tombstone cannot express the deletion lifecycle once a deleted id
legitimately comes back (server-copy restore on revisit, backup import): after
the restore lifts the flag, a pre-delete flush still in flight is
indistinguishable from a post-restore edit and can overwrite the restored
document with pre-delete content. Two rounds of point fixes kept leaking
variants of this race, so this restructures the fence instead.

deleted-stages.ts now keeps a per-stage monotonic deletion epoch plus a
deleted flag. markStageDeleted bumps the epoch; unmarkStageDeleted clears
only the flag and never rewinds the epoch. Every persistence path captures
the epoch at the moment it captures the data it will write (flush-round
snapshot, departing-stage snapshot, aggregate save entry) and re-checks
"captured epoch is current AND not deleted" immediately before each
individual write. Invariants:

- A write captured before a deletion can never land after it, even when a
  same-id restore has lifted the deleted flag (the captured epoch is
  permanently stale).
- A write capturing data after a restore observes the current epoch and
  persists normally.
- A failed deletion lifts only the flag; the restored pending changes are
  re-queued as descriptors, so their flush re-captures current store state
  under the current epoch and is neither dropped nor a stale replay.

Also fixed in the same restructuring:

- Incremental tail writes (currentScene, chats) each re-check independently;
  a delete landing while the first tail write is awaiting now fences the
  chat write instead of riding the earlier check.
- Deleting a classroom evicts it from the warm in-memory store, and
  loadFromStorage treats a warm-but-deleted stage as not loaded (discarding
  the ghost), so navigating Back to a deleted classroom reaches the
  server-restore path instead of rendering an editable ghost whose every
  edit is silently dropped.
- importDatabase records each document's pre-import deletion state and
  reinstates it when a failed import rolls the document back, so an
  outstanding flush cannot recreate the rolled-back document.
- Docstrings on the failed-deletion restore path now state that only dirt
  captured before the deletion is restored; edits refused during the
  deletion window are not part of the snapshot.

New tests cover the epoch invariants at the storage layer (pre-delete rounds
dropped across restores on the incremental, aggregate, and tail paths;
post-restore captures landing; strictly increasing epochs), the scheduler
layer (departing-retry delete+restore straddle; restored dirt flushing under
the current epoch), the warm-ghost restore driven through the real
loadFromStorage, and the import lift/rollback pair.

* fix(deletion): report fenced drops, gate ghost eviction on cascade settlement

Edge hardening around the deletion-epoch fence; the epoch model itself is
unchanged.

- An epoch-stale drop is now reported, not disguised: saveStageData /
  saveStageDataIncremental return a distinct 'stale-dropped' status (entry
  check, every in-mutation re-check, and both tail-write re-checks) instead
  of a shape identical to success. saveToStorage reacts by skipping all
  success bookkeeping - no chatSnapshot rebind to a snapshot that never
  landed, no pending-dirt clearing - and returns false, keeping its
  "true means verified write" contract honest. persistDirtySnapshot keeps
  its existing (correct) semantics explicitly: a drop has nothing to retry.
- Warm-ghost eviction is settlement-gated: the deletion cascade records an
  in-flight bit (begun by deleteStageData, settled in its finally), and the
  deleted-warm branch of loadFromStorage keeps the warm state while the
  cascade is unsettled - a delete can still fail before removing the
  document, in which case the warm state plus the restored pending dirt is
  the only copy of the pre-delete edits. Once settled, the ghost discard
  and server-restore path behave as before.
- Read-side landing re-check: loadFromStorage re-checks isStageDeleted
  after hydration, immediately before set(), mirroring the write-side
  "re-check immediately before landing" discipline - a lock-free
  mid-cascade read can no longer re-materialize a ghost classroom.
- clearStoreForDeletedStage re-checks isStageDeleted at eviction time, so a
  same-id restore completing inside the cascade-tail window is never wiped.
- capturedEpoch is now a required parameter on both storage entry points:
  the default (call-time capture) silently reopened the capture-point/
  validation-point split for future callers; the type system now enforces
  the pairing. All production callers already passed it explicitly.

New tests cover the dropped-status contract, the cascade in-flight
lifecycle (including both failure shapes), keep-warm during an unsettled
delete with end-to-end pending restore after a failed delete, settlement-
then-eviction on success, the eviction guard against a tail-window restore,
and the read-side hydration re-check.

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

* fix(deletion): settle the deleted-warm load by awaiting the cascade outcome

Hardening around the deletion settlement gate introduced previously; the
epoch model is unchanged.

- The deleted-warm branch of loadFromStorage no longer completes the load
  while the deletion cascade is undecided (which exposed a classroom whose
  edits were refused without being restorable, and left a successful
  deletion's eviction with no follow-up reload). It now parks on a per-stage
  settlement promise (stageDeletionSettled) and branches on the outcome:
  a failed delete keeps the warm, restored classroom; a successful delete
  falls through to a full cold load so the server-restore path recovers the
  route; a navigation that moved on during the park is stopped by the load
  token guard. The eviction (clearStoreForDeletedStage) deliberately stops
  claiming a new load token so the parked load stays current - ghost
  re-materialization is fenced by the read-side deleted re-checks instead.
  No deadlock: a parked load holds no document lock, and the cascade never
  waits on a load.
- 'stale-dropped' now propagates through the debounced flush path:
  persistDirtySnapshot returns the sentinel instead of an empty failure set,
  and startFlushRound skips the chatSnapshot rebind on it (mirroring
  saveToStorage) - a falsely rebound baseline would let later chat saves
  no-op-skip chats that never landed and corrupt cross-tab conflict
  detection. Pending-map clearing keeps its empty-failure semantics
  (restored descriptors mint fresh revisions).
- The cascade in-flight state is a counter (begin++/settle--) instead of a
  boolean, and deleteStageData is single-flight per stage (a concurrent
  second call joins the first cascade), so overlapping deletions can never
  expose an undecided cascade as settled.
- The StaleDroppedSave docstring no longer overpromises: a tail
  saveCurrentScene can land after the cascade's clearCurrentScene; the
  orphaned cursor row is ignored by the load path rather than removed by
  the cascade.

Net +8 tests: overlapping-cascade counting, settlement-promise resolution
(success and failure), concurrent double-delete single-flight join, the
parked mid-cascade Back in both outcomes plus the navigation-away guard,
and the fenced flush round keeping an honest chat baseline end-to-end.

* fix(deletion): re-verify store identity on keep-warm resume, re-run joined deletes after a mid-cascade restore

Three hardening refinements on the deletion/persistence fencing:

- loadFromStorage's parked keep-warm branch now mirrors the success
  path's store-identity guard: if a tokenless writer (e.g. a database
  import) replaced the stage during the park, a failed deletion falls
  through to the cold load instead of reporting another classroom as
  the kept warm state. The ghost-discard block is correspondingly
  gated on the deleted flag so the fall-through does not mislabel a
  surviving document as a ghost.

- deleteStageData: a joined call carries its own deletion intent. When
  the first cascade fulfills but a same-id restore lifted the deleted
  flag in the meantime, the joined caller now runs one fresh cascade
  against the restored document instead of reporting the pre-restore
  outcome. Exactly one re-check per call (no recursion); a rejected
  first cascade still propagates unchanged to every joined caller.

- Narrowed the failed-delete restore-ownership comments: the restore
  covers only the pending map plus an in-flight flush round's dirt;
  a departing-stage snapshot is outside that capture and is fenced
  and dropped by design. Comment-only, no behavior change.

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

* fix(roster): gate deleted-warm handling on stage identity, keep an explicit empty roster authoritative

Final-audit fixes, three items:

- loadFromStorage keyed its deleted-warm settlement handling (park /
  keep-warm / ghost discard) behind the scenes.length > 0 shortcut, so a
  zero-scene warm ghost of a deleted classroom skipped it entirely: the
  cold load found no document, the ghost stayed in the store, and the
  classroom loader's server-fallback gate (!getCurrentStage()) never ran
  — the silently-uneditable trap this branch exists to close, in its
  scene-less form. Deletion handling now keys on stage identity alone,
  before any scene-count shortcut; the non-deleted warm skip still
  requires scenes.

- rosterNeedsLegacyFallback collapsed "roster field absent" (document
  predates roster persistence) with "explicitly persisted empty roster".
  A future writer persisting [] on a device whose read-only mirror still
  held stale rows would have its emptied roster resurrected on every
  load. The full-lift branch now triggers only when the field is absent
  (undefined); an explicit [] is authoritative and never probes the
  mirror. No current writer produces [], but the read side no longer
  depends on that invariant.

- The GeneratedAgentConfig docstring claimed the voice fields are not a
  breaking change; that only holds for this codebase's tolerant
  structural validators. The generated stage.schema.json sets
  additionalProperties: false, so consumers pinning an older published
  schema artifact reject documents carrying the new fields. The
  docstring now states both sides honestly.

Tests: a zero-scene deleted warm ghost is restored through the real
loadFromStorage (fails pre-fix), an explicit empty roster does not
resurrect stale mirror rows (fails pre-fix), and the
rosterNeedsLegacyFallback unit matrix covers undefined vs [].

* fix(deletion): re-queue aggregate persistence when a failed deletion is recovered

Direct aggregate saves (saveToStorage: generation completion, server-restore
hydration) run outside the pending map and the flush round, so the deletion
path's pre-delete dirt snapshot cannot describe them. When a deletion bumped
the epoch while such a save was in flight, the save was correctly fenced
('stale-dropped') — but if the deletion then failed before removing the
document, the recovery only re-queued the snapshotted scheduler descriptors.
The fenced aggregate-only content stayed memory-only with no retry anywhere,
and a later reload lost it.

The failed-deletion restore now merges a full re-mark of the aggregate
(structure / stage / outline / currentScene / chats plus a descriptor for
every current scene) into the recovery set, still guarded on the store
holding the stage. Because the flush recaptures the CURRENT store state under
the CURRENT epoch, this necessarily carries whatever the fenced aggregate
save held — and, for the same reason, edits refused by the scheduler during
the deletion window, which previously stayed memory-only as well; the scope
docstrings now say so instead of declaring them excluded.

New integration coverage drives the real store scheduler and the real storage
layer end to end: a genuinely fenced in-flight saveToStorage (generation
completion) plus a pre-removal deletion failure ends with the completion flag
durable on the next flush; a deletion-window scene edit survives the same
way; and a successful deletion re-marks nothing (control). Both recovery
tests fail against the previous restore logic.

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

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

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

be3d313bc3 feat(document): dirty-set incremental saves + operation-level flush (#983)
* feat(document): dirty-set incremental saves + operation-level flush + unload protection

Every store mutation used to trigger a debounced FULL aggregate rewrite —
editing one word rewrote the whole document, scene switches during playback
rewrote it for nothing, and concurrent editors clobbered each other at
document granularity. Mutations now mark precise dirt (scene:<id> /
structure / stage / outline / currentScene / chats): scene edits flush as
version-gated putScene, stage metadata as putStage, structure and outline
changes keep the full-save path, and currentScene/chats no longer touch
the document at all. Dirt entries are revisioned so a mutation landing
during a write is never accidentally cleared, and failed writes retain
their dirt for retry. flushStageSave() drains the debounce single-flight;
agent apply operations await it so each AI edit is durable before its tool
result returns; hidden-page/unload kick a best-effort immediate flush.
The PendingChange type stays neutral about the change unit so a future
operation-log backend can replace the flush internals at one seam.

* fix(document): incremental-persistence review round — bypass-proofing, true drain, no stranded dirt

Structural mutations carry the cursor they changed (and cursor resolution
validates membership on load, so a stale device cursor can never resurrect
a deleted scene). The Stage API now wraps the real store in a guard that
diffs pre/post state and centrally classifies every raw write — whiteboard,
element, canvas, and action-engine mutations can no longer bypass dirty
tracking, and new API namespaces inherit the guard by construction (with a
lint-like inventory test). flushStageSave is a bounded true drain: an
awaiter whose mutation landed mid-flight loops until its own dirt is
durable. setStage hands the old document's dirt to a departing flush
instead of discarding it, and a failed flush always reschedules. Mixed
dirty batches (scene+stage/outline) use the atomic full save — the
incremental fast path is homogeneous-only. Chat-half failures keep the
chats dirt for retry without changing the tolerated-split outer semantics.

* fix(document): reviewer round — drain covers caller dirt, full-path chat retry, stamping unification

flushStageSave's early-return now only fires when the failing round's
snapshot actually covered the caller's dirt — an agent edit landing beside
an in-flight failing round is written before the promise resolves, keeping
the tool-result durability guarantee unconditional. The full-save path
reports chat failures the same way the incremental path does (chats dirt
survives and reschedules; the tolerated-split semantics are unchanged).
The departing-stage flush retries once and its doc-comment states the
best-effort semantics honestly. Stage and scene stamping are extracted and
shared — fixing the incremental putScene branch silently dropping the
order ?? index normalization the full path applies — and the dead outline
mark in setGenerationComplete is gone.

wyucandCodex e39c64cd9e feat(persistence): one-command server-backed stack (compose profile + embedded API + docs) (#982)
* feat(persistence): one-command server-backed stack — embedded API + compose postgres profile

docker compose --profile server-persistence up --build runs exactly two
containers: the app (persistence HTTP server embedded at /api/persistence,
enabled only when DATABASE_URL is set — unset keeps today's browser-only
behavior byte-for-byte) and PostgreSQL 16. Client bootstrap configures both
storage seams against the same-origin route when NEXT_PUBLIC_PERSISTENCE=1,
riding the existing lazy migrations so prior browser data reaches the
server per-course on first open. Dev auth (bearer token + client-asserted
learner header) lives in one overridable module and is loudly documented
as development-grade. Verified end-to-end against the real stack:
document PUT/GET and runtime session create land in Postgres; bad tokens 401.

Co-authored-by: Codex <codex@openai.com>

* fix(persistence): review round — structural bootstrap ordering, retryable init, honest failure surfaces

The bootstrap side-effect import moves into the two storage seam entry
modules, so any module graph that can resolve a store necessarily
evaluates it first — no client-entry ordering luck, and the two configure
calls are all-or-nothing. A failed server init clears its cached promise
(next request retries instead of permanent 500s). listStages rethrows
backend failures and the dashboard surfaces a persistence-unavailable
error instead of rendering an empty list that reads as data loss. Docs
state the build-time nature of NEXT_PUBLIC_PERSISTENCE, the real token
boundary (any visitor can extract it and impersonate any learner —
localhost/trusted-network only), and the correct postgres password
rotation. Dev-token compare is timing-safe; the handler singleton lives
on globalThis so HMR cannot leak pools.

Co-authored-by: Codex <codex@openai.com>

* fix(persistence): review response — no-confidentiality wording + adapter round-trip coverage

The token docs now state plainly that the NEXT_PUBLIC token is compiled
into the public bundle and provides no confidentiality or user isolation
(its only role is keeping unrelated scanners off a trusted network). The
Fetch/Node adapter — the route's most bug-prone code — gains a round-trip
integration test: PUT body streaming, 201 with multi-value headers, 204
empty body, and encoded path segments reaching the handler un-decoded.

wyucandCodex 5cef056d17 feat(storage): server-backed documents — HTTP contract, Postgres backend, one reference server for both stores (#979)
* ci: whitelist the document-server-backend integration trunk

* feat(storage): DocumentStore HTTP contract + client + reference-server routes (1B PR1) (#975)

Mirrors the runtime line's server-backed delivery for the document store:
a documented /documents HTTP contract (validation/not-found/FUTURE_VERSION
taxonomy; authorization stays a deployment concern via injected hooks with
an any-authenticated default), an HttpDocumentStore that runs the same
validators and migrate-on-read semantics as the browser backend before and
after the wire, and document routes on the shared reference server — one
server, both stores. The backend-agnostic document contract suite now runs
against HTTP → reference server → browser store.

Co-authored-by: Codex <codex@openai.com>

* ci: whitelist the trunk in the storage PG contract workflow too

* feat(storage): PgDocumentStore — Postgres document backend (1B PR2) (#976)

Implements the full DocumentStore contract over document_stages /
document_scenes / document_outlines, reusing the pure adapter split so
every backend shares one aggregate semantics: saveDocument replaces the
aggregate in one transaction under the stage row's FOR UPDATE lock
(vanished scenes deleted, outline row added/removed — omission means
deletion), incremental putStage/putScene/deleteScene take the same
current-version gate as the browser backend, loads read FOR SHARE and
migrate without writing back, listings never touch content, and deletes
cascade by FK. The document contract suite is PG-gated the same way the
runtime one is; local coverage comes from stubbed-queryable unit tests.

Co-authored-by: Codex <codex@openai.com>

* feat(document-store): sealed bootstrap injection seam for the document backend (1B PR3) (#977)

configureDocumentStorage mirrors the runtime seam: module-level bootstrap
injection sealed after first resolution, a factory that receives the app
validators so a server-backed store cannot silently skip them, and
reset-for-tests wiring. A deployment swaps the browser document backend
for HttpDocumentStore without touching app code. Storage README roadmap
updated — the document HTTP/PG backend items are done.

Co-authored-by: Codex <codex@openai.com>

* fix(storage): 1B final-review hardening — error classification, JSON-safety, body limits, parity coverage (#978)

Unversioned legacy incremental writes classify as 400 instead of leaking a
500; document/scene reads assert JSON safety before serialization so a
structured-clone value fails loud (500 NOT_JSON_SAFE naming the path)
instead of silently converting; a shared streaming body reader bounds
request bodies (default 32 MiB, 413 PAYLOAD_TOO_LARGE, option exposed
through every handler factory); the putStage stale/future guards and
corrupt-stamp listing tolerance move into the shared contract suite so all
four backends prove them; both HTTP store errors retain structured details.

Co-authored-by: Codex <codex@openai.com>

* refactor(storage): typed document version/not-found errors replace prose classification (#980)

DocumentVersionError (future | not-current, storedVersion) and
DocumentNotFoundError now carry the classification the server previously
regex-derived from message prose — instanceof matching mirrors the runtime
sibling's RuntimeAppendConflictError pattern, so a wording change can no
longer silently break status mapping. The prose fallback remains, after
the typed checks, solely for third-party DocumentStore implementations.
The HTTP client rematerializes 409s as DocumentVersionError for symmetry,
and http.ts's private validator fields are renamed to match the public
option names all three backends already share.

Main's three call sites built static storeState blocks that runAgentLoopFn
never consumed (it always rebuilds fresh state via getStoreState); the quiz
read cutover replaced that callback with the async two-phase RuntimeStore
read, leaving the template field with zero consumers. Drop it.

* feat(storage): conform HTTP/PG backends and reference server to RuntimeAppendOptions

The quiz write path's expectedLastSeq / sessionTransition / RuntimeAppendConflictError
semantics existed only in the browser backend; server-backed deployments would
silently accept conflicting appends and leave completed sessions active. Forward
the options over the wire, detect conflicts atomically under the PG transaction,
map them to HTTP 409 RUNTIME_APPEND_CONFLICT, and rematerialize the typed error
client-side so quiz retry logic works across every backend.

Co-authored-by: Codex <codex@openai.com>

* fix(chat): Pi single requests build storeState via the async runtime quiz read

Pi bypasses runAgentLoop's per-iteration getStoreState and serializes the
request template straight to /api/chat/pi, which rejects bodies without
storeState. Extract the fresh-snapshot builder (async RuntimeStore quiz read
with the scene-transition guard) and call it on the Pi path too.

* feat(runtime): playback cutover — cursor in KV, discussion facts in RuntimeStore (#956)

The fourth and last runtime family. Consumed-discussion facts become
append-only 'playback' records folded into a set at read (at-least-once
appends, no conflict machinery); the resume cursor is device-scoped
last-write-wins KV per the amended #779/#869 split. sessionStorage keeps
same-tab priority; KV takes over on fresh tabs/reloads. The dead Dexie
playbackState machinery is retired, with a one-time lazy migration of any
legacy row (cursor half + facts half) before deletion, and stage deletion
now clears both the KV cursor and any unmigrated legacy row.

---------

Co-authored-by: Codex <codex@openai.com>

* fix(playback): persist discussion facts on every consumption path (#957)

* fix(playback): persist discussion facts on every consumption path (final-review P0+P1s)

- The engine now publishes a progress snapshot the moment a discussion is
  consumed (join / skip / unselected-agent auto-skip). onProgress otherwise
  fires before the discussion action executes and a discussion is the scene's
  last action, so the fact never reached persistence.
- Reads fold records across ALL playback sessions in the learner partition
  (mergeLearner deliberately preserves same-kind sessions from both keys).
- Legacy migration appends only not-yet-durable facts, so an interrupted
  migration resumes instead of dropping the tail.
- recordConsumedDiscussion reports durability; the component drops failed ids
  from its observed set so a later progress tick retries (at-least-once).

* test(e2e): live verification of the playback persistence chain

Seeds a deterministic stage straight into the Dexie DB, starts the lecture
via the canvas overlay, and asserts the full chain: discussion auto-skip
appends a discussionConsumed record to maic-runtime, the device cursor lands
in KV, and both survive a fresh browsing context (empty sessionStorage).

* refactor(playback): consumed-discussion state is volatile by decision — cursor-only persistence (#959)

Product ruling on #869's fourth family: playback learner state is front-end
ephemeral UX, not learner data. A re-shown proactive card auto-skips, joined
discussions' content already lives in chat runtime records, and no replay
export / analytics consumer exists — so durable facts bought nothing over
in-memory + same-tab sessionStorage. Drop lib/playback/runtime.ts and the
RuntimeStore facts wiring; keep the device-scoped KV resume cursor (the half
with real UX value), the engine's consumption-time progress snapshot (cursor
freshness), and the legacy Dexie retirement (cursor half migrates, row
deletes, consumed ids are dropped).

* ci: whitelist the document-cutover integration trunk for PR checks

* feat(document): widened-stage contracts + app document seam (#860 follow-up, PR1) (#961)

Package: MaicDocument/DocumentStore/StageRow gain a TStage parameter
(defaults keep existing users unchanged), BrowserDocumentStore accepts an
injectable validateStage, and a version-guarded putStage closes the rename
read-modify-write race — same current-version gate as putScene.

App: lib/document/ seam — AppDocument types (currentSceneId is device
state, not document data, and the app stage validator rejects it), a
four-kind scene validator (slide/quiz delegate to the DSL; interactive/pbl
validate envelope + discriminant binding only), and pure legacy
canonicalizers (type rebound from content.type, singular whiteboard →
whiteboards, outline envelope). No consumer switches off Dexie yet.

* feat(document): stage-storage cutover + locked lazy migration (PR2) (#962)

* feat(document): cut stage/scene persistence over to DocumentStore with locked lazy migration (PR2)

stage-storage now persists through the lib/document seam: aggregate
saveDocument with a mandatory outline envelope (omission means deletion in
the contract; ordinary saves fall back to the stored envelope), lazy
per-stage migration under a Web Lock (destination authoritative, one
coherent legacy snapshot, save-verify-marker, legacy rows retained
read-only; no-lock environments read legacy without migrating),
currentSceneId in device KV, rename via version-guarded putStage, and a
list that merges legacy-only stages until they migrate. stageOutlines'
second write authority folds into the document service, making the final
scene set and generationComplete one atomic commit.

Co-authored-by: Codex <codex@openai.com>

* fix(document-store): relocate the persistence seam out of lib/document

lib/document/ is the server-side content-extraction domain (sharp, cloud
SDKs); exporting the persistence seam from its barrel dragged node-only
modules into the client bundle and broke the Turbopack build. The seam now
lives in lib/document-store/ with its own barrel, and the extraction barrel
is restored. Client-only guards become capability probes (indexedDB /
localStorage presence) so injected node test environments keep working
while a true server render still fails loud.

* fix(document-store): no-lock write classification + lock-order inversion (PR2 fix round)

Lock order is now per-stage document lock → global runtime epoch (a save
never waits on a document lock while occupying the shared epoch, which
deadlocked against fair-queued maintenance). Without Web Locks, mutation
classifies instead of refusing wholesale: destination-backed and genuinely
new documents accept the product's established lock-free/LWW risk, while a
legacy-only document stays read-only so two authorities cannot fork —
matching the chat-cutover-era acceptance suite, whose save assertions now
verify through the public API instead of legacy Dexie rows.

ZIP classroom/video exports read stage metadata through the seam; classroom
import builds one canonical aggregate under the per-stage lock and writes
canonical 'whiteboards' (fixing the import-side singular-alias defect the
manifest never had); backups become versioned document aggregates that
finally include outline envelopes, while old {stages, scenes} backups are
accepted through the legacy canonicalizers; clearDatabase now clears
maic-documents and the seam's KV keys so clear-cache cannot strand
documents; deleteStageWithRelatedData is deprecated in favor of
deleteStageData. Four e2e seeders target maic-documents directly;
classroom-interaction stays legacy-seeded to exercise real-UI lazy
migration.

- Backup rollback restores pre-existing destination documents (and imported

- The skip-migration path only writes its marker after reconciling the
  legacy snapshot against the authoritative destination; a divergent
  snapshot logs and stays discoverable instead of being falsely certified
- Migration's destination write enrolls in the global shared storage epoch
  (per-stage -> global order), so clearDatabase's exclusive epoch can no
  longer race a lazy migration into resurrecting a document

* fix(review): scene-id boundary for quiz context + 4xx for malformed sessionTransition (P3 pair)

Review findings on #955: didActiveSceneRemainUnchanged compared the active
scene by object identity, so a store update reallocating the scene during
the async quiz read dropped the learner's graded answers from that turn's
request — the scene id is the real boundary. The records route now
classifies a malformed sessionTransition as a validation failure instead of
letting the store's throw surface as a 500.

* fix(playback): superseded-engine cursor guard + migration write-window recheck

Second-vendor review of the #959 shrink (requested after the cross-review
noted it had single-vendor coverage) found: an engine orphaned by a scene
switch during async lecture resume could pass the idle-only recheck, be
resurrected, and publish its old scene's progress over the new scene's
debounced cursor — the resume continuation now requires identity with the
installed engine, and onProgress drops snapshots from superseded engines.
The legacy cursor migration also rechecks KV immediately before its write
so a concurrent tab's newer cursor cannot be overwritten and orphaned by
the legacy-row delete.

Backup assembly appends read-only canonicalized aggregates for legacy-only
stages the lazy migration could not persist (no-Web-Locks environments) —
courses visible in the app can no longer vanish from an export. A
device-scoped storage generation now fences document mutations: clears bump
it inside their exclusive section, and any save or migration commit that
entered before the clear re-reads it inside the shared epoch and fails loud
instead of repopulating a wiped store.

Co-authored-by: Codex <codex@openai.com>

* fix(document): review round 2 — legacy-only chat backup coverage + full-width generation fence (#972)

Backups now enumerate runtime chat sessions for every exported document,
not just store-backed ones — a legacy-only course's chat history (the chat
and document cutovers are independent seams) no longer drops out of the
export; the runtime read injects an empty legacy chat store since legacy
rows are collected by direct table reads, which also keeps the export
working without Web Locks. The storage-generation fence now guards every
mutating store method, with the exclusive-epoch delete cascades passing
storageSharedLockHeld so the guard cannot self-deadlock against their own
hold.

* feat(video-export): service-backed MP4 render + in-app one-click export (#866)

Adds the last mile of classroom video export: turning the self-contained
Hyperframes project ZIP (#865) into an MP4 via an isolated render service,
one-click in-app.

- render-service/: standalone Node 22 + Chromium + FFmpeg container wrapping
  @hyperframes/producer's library API. Async job model (POST /render -> 202
  jobId, GET poll, GET download, DELETE cancel). Swappable JobStore /
  ArtifactStore seams (in-memory + local-disk now; Redis/S3 + presigned-302
  download later) so it scales horizontally without changing the HTTP contract.
  Concurrency + per-user guards are config knobs.
- App integration: thin Next proxy routes under app/api/export-video/* (forward
  only, no rendering) + capability probe. use-render-video.ts uploads the ZIP,
  polls via runPolledTask, downloads the MP4; shared buildExportZip prefix with
  the existing ZIP path. Export menu gains resolution/fps/quality selectors and
  a progress bar; degrades to ZIP download when RENDER_SERVICE_URL is unset.
- docker-compose: render-service under an opt-in "video-export" profile.
- Entry is main.ts (not server.ts): the producer auto-starts its own server on
  :9847 when the process entry path ends with /src/server.ts.

Verified end-to-end in the container: rendered a real 640s (10.7 min) classroom
ZIP to a valid H.264 720p + AAC MP4 (duration matches source) in ~9.6 min
(~0.9x realtime, 4-worker frame capture). Degrade path, queued-cancel + cleanup,
and per-user 429 guard all exercised. pnpm check / lint / tsc / i18n pass.

* feat(video-export): global render progress store, percent+ETA UI, ring on export button (#866)

Addresses two UX issues found while driving the in-app MP4 export:

1. Progress display was raw and unfriendly (showed producer's English stage
   strings like "Capturing frame 5130/19220") and had no time estimate. Now the
   menu shows only "<percent>% · about <remaining> left". ETA is computed from a
   recent-speed estimate (percent-per-ms over the last sample), EMA-smoothed —
   which tracks the render's non-uniform pace (prep -> frame capture with a
   4->1 worker drop -> encode) far better than a whole-run average, and never
   shows a stale/rising ETA.
2. Switching scenes mid-render unmounted the export menu and lost the progress
   (and reset the local "already rendering" ref, allowing a duplicate submit).
   The whole render lifecycle now lives in a global store
   (lib/store/video-render.ts), so progress survives menu close / scene switch
   and duplicate submits are guarded by status. A persistent CircularProgress
   ring on the export button shows live progress whether or not the menu is open.

Also fixes the progress scale: the producer reports progress as 0..100, but our
HTTP contract (and success path) is 0..1 — the service now normalizes it, so the
client no longer showed "2000%".

- lib/store/video-render.ts: new global store owning submit->poll->download,
  recent-speed ETA, duplicate-submit guard.
- lib/video-export-app/use-render-video.ts: thin facade over the store.
- components/ui/circular-progress.tsx: lightweight SVG progress ring.
- components/stage/{header-controls,video-export-menu}.tsx: ring on the export
  button; menu shows percent + ETA, subscribes to the store.
- render-service/src/render-manager.ts: normalize producer progress 0..100 -> 0..1.
- i18n: percent/ETA strings across all 8 locales (drops the stage-based string).
- render-service/package-lock.json: complete integrity hashes (reproducible npm ci).

Verified: ETA logic checked against the real segmented render curve (worker drop
raises ETA, encode speedup drives it to ~0); progress scale fix confirmed live
against the container (0.2 -> 20%). tsc / lint / prettier / i18n pass.

* fix(video-export): persist render options in the store, not the menu component

Selecting 720p/24fps/draft, switching scenes, and reopening the export menu
showed the defaults again (1080p/30/standard). The selections lived in the
VideoExportMenu component's local state, which reset when the menu unmounted on
a scene switch — the running render still used the chosen options, but the UI
misrepresented them.

Move resolution/fps/quality into the global video-render store (with a
setOptions action). The menu now reads/writes the store, so selections survive
menu close / scene switch, and while a render runs the selectors reflect the
options that render is actually using. startRender() reads options from the
store instead of taking them as an argument.

* fix(video-export): deployment correctness + resource/isolation controls (PR #937 review)

Addresses the blocking findings from wyuc's review. Output fidelity was fine;
these harden deployment and production resource/isolation boundaries.

#1 Compose advertised MP4 but couldn't render in prod:
- Capability now probes the service's /health (checkRenderServiceHealth), so a
  configured-but-absent service reports disabled and the UI degrades to ZIP
  instead of 502-ing.
- RENDER_SERVICE_URL is operator-supplied trusted config, so the proxy no longer
  runs it through the SSRF guard — the one-command `docker compose --profile
  video-export up` now works without globally weakening SSRF via
  ALLOW_LOCAL_NETWORKS. resolveRenderServiceUrl() is now synchronous.
- Client degrades to ZIP on any failed submit (not only 501).

#2 Unbounded upload/queue (ZIP-bomb / DoS):
- unzip.ts bounds the archive via fflate's filter BEFORE decompression: entry
  count, per-entry and total expanded size, and compression ratio.
- Proxy rejects oversized uploads (413) by Content-Length before forwarding.
- RenderManager enforces a global queue-depth cap (RENDER_MAX_QUEUE).
- All limits are env-tunable knobs in config.ts.

#3 Per-user guard was ineffective + admission ran after extraction:
- Identity is derived server-side (client IP) and forwarded as x-openmaic-client;
  the service ignores any client-supplied userId, and the proxy strips it.
- Admission is split into reserve()/submit()/release(): the slot is reserved
  BEFORE extraction, so a rejected caller never triggers a decompression.

Additional risks:
- Per-job wall-clock watchdog (RENDER_JOB_DEADLINE_MS) aborts + fails a hung
  render so it can't hold a slot/scratch forever.
- Download proxy bounds only the time-to-headers, not the body stream, so large
  MP4s over slow links no longer truncate.
- Client cancels the server job (DELETE) when a started render fails/times out.
- Compose puts render-service on an internal:true network (no host/internet
  route), sandboxing the Chromium that runs the uploaded HTML; the export ZIP is
  self-contained so no outbound is needed. README documents the standalone caveat.

Not closing #866: the smoke/golden-render CI acceptance criterion remains a
follow-up (see PR description).

Verified in-container: legal render 202; ZIP-bomb (entry-count + compression-
ratio) rejected 400 before any decompression; per-identity guard 429 with a
spoofed multipart userId ignored; reserve-before-extract leaves no scratch dir
on rejection; watchdog aborts an overrunning job and frees the slot. tsc / lint /
prettier / i18n pass; render-service tsc passes.

* fix(video-export): real audio durations + burned-in subtitles (PR #937 review)

Two export-fidelity issues found in wyuc's deeper E2E:

A. Narration was scheduled from estimated durations, cutting audio off mid-
   sentence and advancing the timeline early. The scheduler trusted
   AudioFileRecord.duration (recorded only since #861), so the many existing
   classrooms without it fell back to text-length estimates — measured 4.35s
   average / 10.23s max underestimate across 47 clips. timeline-deps now probes
   the real duration from each narration blob via an off-document <audio>
   (symmetric to the existing video probe), preferring it over the stored
   duration, then the estimate only when no audio asset exists. Everything
   downstream (narration starts, scene/total duration, subtitle cues) re-derives
   from the corrected value in the pure compiler — no compiler change needed.

B. The final MP4 had no subtitles (only H.264+AAC), and the ZIP's SRT/VTT used
   the same estimated boundaries. The emitter now renders a burned-in subtitle
   overlay: one caption box + a hidden div per cue, revealed/hidden by the paused
   GSAP timeline at each cue's start/end (corrected timings from A), so Chromium's
   frame capture bakes them in. The producer has no subtitle track of its own, so
   burn-in is the v1 approach.

Verified: emitter unit tests + snapshot updated (subtitle overlay + toggle
statements, escaped text, hidden-by-default); 82 video-export tests pass incl.
the determinism red-line proxy. Rendered a synthetic subtitle project through the
container and confirmed by pixel analysis that captions appear only within their
cue window (2429 near-white px in the caption band at t=1.5s vs 0 at t=0.05s).
tsc / lint / prettier / i18n pass.

* fix(video-export): subtitle layout + upload/admission hardening (PR #937 review)

Address the three P1 blockers plus actionable P2s from the 6a585c29 review.

P1:
- emit-hyperframes: stack every subtitle cue in one grid cell and toggle
  display:none/inline-block, so inactive cues leave the flow instead of
  pushing the active cue up into the slide title. Adds a multi-cue
  regression test the single-cue snapshot couldn't catch.
- render route + service: cap the upload by actual bytes (capBodyStream),
  not the spoofable Content-Length; the app now streams the multipart body
  through instead of buffering it via formData(). maxUploadBytes is now read.
- render-service: move makeProjectDir() inside the release()-guarded block
  so an ENOENT/ENOSPC no longer permanently leaks the admission slot; mkdir
  the scratch root at startup for the standalone path.

P2:
- config: allow RENDER_MAX_JOBS_PER_USER=0 to disable the per-identity guard.
- timeline-deps: per-probe timeout + bounded concurrency so a stuck audio
  blob can't wedge export in "compiling" forever.
- render route: only trust x-forwarded-for/x-real-ip under
  TRUST_PROXY_HEADERS=true; otherwise all callers share one "direct" bucket.
- render-service: add vitest tests (unzip limits/traversal, reservation
  arithmetic, body cap, config zero-disable) and a dedicated CI job.

* fix(video-export): sync render-service lockfile so `npm ci` passes in CI

The vitest devDependency's transitive esbuild@0.28.1 (and its platform
optionals) were missing from package-lock.json, so the new CI job's
`npm ci` failed with EUSAGE. Regenerated the lockfile from a clean install.

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

* fix(video-export): dedupe esbuild so render-service `npm ci` installs on linux

@hyperframes/core pins esbuild@0.25.12 exactly, hoisting it to the top and
forcing vite@8 (via vitest) to keep a nested esbuild@0.28.1 copy. npm fails to
flag that nested copy's platform-specific optionals as optional, so `npm ci`
tried to install @esbuild/aix-ppc64 on linux and died with EBADPLATFORM.

Add an `esbuild: 0.28.1` override so a single copy is shared (satisfies tsx
~0.28 and vite ^0.27||^0.28); esbuild is build-time only, so pinning the
producer's bundled build tool is runtime-inert.

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

* fix(video-export): resource/isolation hardening (PR #937 round-2 review)

Address the round-2 P1/P2/P3 findings (P1#1 lockfile EBADPLATFORM was already
fixed by the earlier esbuild-dedupe commit; CI Render Service job is green).

P1:
- Admission before buffering (#2): the render service now reserve()s the slot
  from the header identity BEFORE parsing/buffering the multipart, so concurrent
  near-cap uploads are bounded by the queue depth, not just each body by the cap.
- Chromium egress lockdown (#3): the producer exposes no browser-arg hook and the
  render shares the internal network with the app, so a container entrypoint
  installs an iptables egress lockdown (drop all outbound except loopback +
  established replies) then drops privileges. Needs CAP_NET_ADMIN (added in
  compose); graceful warn-and-continue if unavailable. The self-contained ZIP
  needs no outbound.
- Default one-render bottleneck (#4): with no trusted proxy every caller is
  "direct", so RENDER_MAX_JOBS_PER_USER=1 throttled the whole deployment. Default
  compose now sets it to 0 and relies on concurrency + global queue caps.
- Non-blocking bounded extraction (#5): unzipSync -> fflate async unzip (worker,
  off the event loop), keeping the pre-decompression filter; default expanded
  ceiling 1GB -> 512MB; a semaphore caps concurrent extractions; compose adds a
  container mem_limit.

P2:
- Raise the app submit timeout/maxDuration (300MB upload can't finish in 60s).
- video-render store: only degrade to ZIP when the service is genuinely
  unavailable (501/unreachable); surface real 429/413/5xx instead of an
  unsolicited download.
- useExportVideo dedupe guard moved to module scope so it survives the menu
  unmounting (no second concurrent ZIP pipeline).
- .env.example: RENDER_SERVICE_URL bypasses SSRF; drop the ALLOW_LOCAL_NETWORKS note.

P3:
- Deadline overruns are marked failed (not cancelled).
- submit() decrements the identity slot if jobs.create throws (no leak).
- CI sets PUPPETEER_SKIP_DOWNLOAD; unzip tests use tiny fixtures + low env limits.

Tests: render-service now 22 tests (unzip limits/traversal, admission incl.
create-leak, body cap, semaphore, config); app video-export suite unchanged.

* fix(video-export): buffer under the extraction permit + fail-closed egress (PR #937 round-3)

Address the two remaining round-3 P1 boundary blockers.

P1#1 — buffering was outside the gate: `bounded.formData()` materialized the
whole uploaded file into memory BEFORE `extractionGate.run()`, so up to
RENDER_MAX_QUEUE (20) admitted bodies could each buffer ~300MB (≈6GB vs the 4g
mem_limit) before the 2-permit gate. Move the entire RAM-heavy section —
formData buffering, file read, and unzip — INSIDE the permit; the queue
reservation still runs first (a rejected caller consumes nothing). Requests
beyond the permit wait with their body unconsumed (socket backpressure), so at
most maxConcurrentExtractions bodies are buffered at once. Refactored main.ts
into a testable `createApp(deps)` factory and added an integration test proving
peak concurrency in the buffering+extraction section never exceeds the permits.

P1#2 — egress lockdown failed open: the entrypoint warned and started normally
if iptables setup failed, so /health stayed green while Chromium could reach the
app. With RENDER_EGRESS_LOCKDOWN=true (default) it now FAILS CLOSED — exits
non-zero if not root, iptables is missing, or the rules don't apply. Operators
accepting an unisolated setup opt out with RENDER_EGRESS_LOCKDOWN=false. Added
scripts/egress-smoke.sh to assert the boundary (lockdown active, loopback works,
new outbound blocked).

Verified: image builds; container boots as `render` with lockdown active and
serves /health; fail-closed exits 1 without CAP_NET_ADMIN; egress smoke passes
(outbound blocked); 23/23 render-service tests + tsc; app tsc + root prettier clean.

wyuc 34448beb6c feat(storage): server-backed runtime — pluggable backend seam, HTTP contract, Postgres backend, reference server (#939) (#946)
* ci: run PR checks against the runtime-server-backend integration branch (#939)

* feat(storage): RuntimeStore HTTP contract + HttpRuntimeStore client (#939 Part B) (#940)

* feat(storage): RuntimeStore HTTP contract + HttpRuntimeStore client (#939 Part B)

- documented JSON HTTP contract for every RuntimeStore operation
  (server-assigned seq, learnerKey derived from auth — never trusted
  from the request, machine-readable error codes, idempotency notes)
- HttpRuntimeStore client with injected fetch + auth headers hook;
  session reads (including createSession responses) migrate forward
  on the runtime line so an older server cannot leak stale envelopes
- conformance test server bridging the contract onto the browser
  backend; full runRuntimeStoreContract green over HTTP plus error
  mapping cases

* fix(storage): harden HTTP runtime backend after cross-review (#939 Part B)

Cross-review fixes:
- appendRecord gates payloads through assertJsonValue: fail loud on
  values JSON cannot represent (Map, Date, NaN, nested undefined, NUL
  strings) instead of silently mangling them in transit; payload
  domain documented in the contract
- appendRecord/listRecords responses validate via validateRuntimeRecord
  (server-assigned seq is no longer trusted verbatim) and listRecords
  sorts by seq like listSessions already sorted defensively
- request headers no longer require an ambient Headers constructor
  when fetch is injected
- conformance server classifies errors structurally (existence checks,
  DSL validators, version stamps) instead of regex-sniffing messages
  that interpolate caller-controlled ids
- router preserves empty path segments so empty-key calls keep browser
  no-op semantics instead of shifting onto other routes
- stray runtimeDslVersion/seq in request bodies are ignored (store-
  assigned wins), matching the browser reference; docs updated
- loopback integration test exercises the real listening server
- docs state the conformance server is test-only; auth-derived
  learnerKey is Part D's reference server

* fix(storage): round-2 cross-review hardening for the HTTP backend (#939 Part B)

- json-value guard rewritten: additionally rejects -0, symbol-keyed and
  non-enumerable own properties, and non-index own properties on arrays;
  U+2028/U+2029 are accepted again (they round-trip through JSON per
  RFC 8259 — rejecting them lost legitimate pasted text)
- conformance server classifies racing duplicate creates as 409 via a
  structural post-check, gates payloads and merge learner keys as 400
- segment() rejects '.'/'..' ids the URL layer would fold away
- list responses must be arrays and mergeLearner's moved must be a
  finite number, else a typed MALFORMED_RESPONSE error

* fix(storage): round-3 cross-review hardening for the HTTP backend (#939 Part B)

- json-value guard: NUL is rejected in object keys too, and unpaired
  UTF-16 surrogates are rejected in string values and keys (jsonb
  refuses both; other JSON stacks corrupt lone surrogates to U+FFFD)
- typed storage errors survive non-object 200 responses instead of
  degrading into TypeErrors on .id access
- mergeLearner's moved must be a non-negative integer
- conformance server classifies missing/non-object request bodies as
  400 VALIDATION_FAILED
- createSession/appendRecord gate the full init envelope, not only the
  payload (stray Date/undefined properties, NUL in ids)

* fix(storage): round-4 convergence fixes for the HTTP backend (#939 Part B)

- envelope JSON gate tolerates explicitly-undefined optional anchors
  (sceneId: undefined behaves like omission, matching the browser)
- body-carried identifiers reject '.'/'..' so nothing persists that
  the URL layer cannot later address; conformance server mirrors it
- mergeLearner keys pass the JSON-domain gate on client and server
- json-value guard v4: rejects enumerable accessors (validation/serialize
  TOCTOU), Array subclasses and null-proto arrays, prototype-supplied
  array indices; sparse-array test now constructs a genuine hole

* fix(storage): round-5 convergence fixes for the HTTP backend (#939 Part B)

- undefined-stripping is limited to the DSL-declared optional anchors
  (sceneId/actionIndex/subAnchor); any other undefined member fails the
  JSON gate loud instead of being dropped silently
- json-value guard: array and object prototype checks are realm-agnostic
  (chain-shape instead of identity), so ordinary values from another
  realm are accepted while subclasses stay rejected; shared
  isLosslessJsonString predicate exported for SQL key guards
- conformance server merge route validates target-key addressability

* fix(storage): close the toJSON prototype channel in the JSON guard (#939)

toJSON is the single channel through which a prototype can alter JSON
output — prototype properties never serialize and own accessors are
already rejected — so refusing any value with a callable toJSON closes
prototype influence on serialization entirely, including prototypes
crafted to pass the realm-agnostic chain-shape check.

* fix(storage): probe toJSON via descriptor walk, not property read (#939)

Reading value.toJSON would execute an inherited accessor, letting a
stateful getter hide from validation and reappear at stringify time.
The probe now walks own descriptors up the prototype chain without
invoking any user code. Post-validation mutation of the caller's object
graph is documented as out of scope — it is equally unpreventable for
every other validated property.

* fix(storage): toJSON probe mirrors JSON.stringify semantics exactly (#939)

The own-most descriptor decides: absent is safe, a non-callable data
value is an ordinary shadowing member and is safe, a callable data
value is rejected, and an accessor is rejected because it cannot be
inspected without invoking it. No daylight remains between the guard
and the serializer on this property.

* feat(storage): PgRuntimeStore — Postgres runtime backend (#939 Part C) (#941)

* feat(storage): PgRuntimeStore — Postgres runtime backend over an injected queryable (#939 Part C)

- PgRuntimeStore implements RuntimeStore over a minimal injected
  Queryable (node-postgres and PGlite both satisfy it) — the package
  keeps zero runtime dependencies beyond @openmaic/dsl
- runtime_sessions / runtime_records schema exported as
  RUNTIME_PG_SCHEMA with idempotent ensureSchema()
- appends serialize per session via a session-row lock; MAX(seq)+1
  and the insert share one transaction, UNIQUE(session_id, seq) plus
  bounded retry backstop non-cooperating writers
- envelope semantics mirror the browser backend: version stamping,
  validation gates, migrate-on-read, fail-loud on future-stamped rows
- full runRuntimeStoreContract green on PGlite plus PG-specific cases
  (concurrent-append seq atomicity, ensureSchema and mergeLearner
  idempotence)

* fix(storage): require pinned transactions + JSON payload gate in PG backend (#939 Part C)

Cross-review fixes:
- withTransaction is now required; the BEGIN/COMMIT fallback is removed
  (on a pg Pool it spread BEGIN/body/COMMIT across different connections
  — no real transaction, leaked idle-in-transaction clients, broken
  mergeLearner atomicity; on a shared pinned client concurrent calls
  interleaved transactions)
- single-statement deletes no longer wrap in a transaction hook call
- appendRecord gates payloads through assertJsonValue: fail loud on
  values JSON cannot represent (Map, Date, NaN, nested undefined, NUL
  strings) instead of silently persisting something different
- append retry also covers 40001/40P01; READ COMMITTED assumption
  documented at the retry loop
- ensureSchema documented as create-only; redundant stage index dropped
- deterministic interleaving test proves the 23505 retry path; real
  PostgreSQL contract lane added (postgres:16 service workflow, pg
  driver suite skipped locally without PG_CONTRACT_URL)

* fix(storage): round-2 cross-review hardening for the PG backend (#939 Part C)

- json-value guard rewritten (shared with the HTTP backend): additionally
  rejects -0, symbol-keyed and non-enumerable own properties, and
  non-index own properties on arrays; accepts U+2028/U+2029
- storage-pg-contract workflow now triggers for the runtime-server-backend
  integration branch and fails loud (STORAGE_PG_CONTRACT_REQUIRED=1)
  when PG_CONTRACT_URL is missing instead of silently skipping
- loadSession distinguishes corrupt non-object rows from absent rows so
  getSession fails loud instead of reporting the session missing

* fix(storage): round-3 cross-review hardening for the PG backend (#939 Part C)

- json-value guard (shared): NUL rejected in object keys, unpaired
  UTF-16 surrogates rejected in values and keys
- createSession/appendRecord gate the full persisted envelope through
  assertJsonValue, not only the payload — stray Date/undefined
  properties and NUL in ids fail loud instead of silently diverging
  from the returned record or leaking raw 22P05
- real-PG lane covers a genuine 23505 conflict from a second
  connection and recovery after an aborted transaction
- retry-set asymmetry and mergeLearner's unbounded lock set documented

* fix(storage): round-4 convergence fixes for the PG backend (#939 Part C)

- NUL/lone-surrogate lookup and delete keys resolve to absent/no-op
  instead of leaking 22021 driver errors; setSessionStatus reports the
  session missing; mergeLearner from-key moves 0
- mergeLearner destination key passes the JSON-domain gate fail-loud
- envelope JSON gate tolerates explicitly-undefined optional anchors,
  matching the browser backend
- json-value guard v4 (shared) + tests for accessors, Array subclasses,
  prototype-supplied indices

* fix(storage): round-5 convergence fixes for the PG backend (#939 Part C)

- appendRecord pre-checks the session key like every other lookup path,
  so a NUL/lone-surrogate sessionId reports 'no session' instead of
  leaking a 22021 driver error
- the queryable-key predicate now structurally reuses the shared
  isLosslessJsonString export instead of restating the string rule
- undefined-stripping limited to the DSL-declared optional anchors
- json-value guard: realm-agnostic prototype checks (shared)

* fix(storage): close the toJSON prototype channel in the JSON guard (#939)

Shared guard change with the HTTP backend branch; adds the crafted
null-proto-prototype regression test. Both final-gate reviewers
independently converged on this same channel.

* fix(storage): probe toJSON via descriptor walk, not property read (#939)

Reading value.toJSON would execute an inherited accessor, letting a
stateful getter hide from validation and reappear at stringify time.
The probe now walks own descriptors up the prototype chain without
invoking any user code. Post-validation mutation of the caller's object
graph is documented as out of scope — it is equally unpreventable for
every other validated property.

* fix(storage): toJSON probe mirrors JSON.stringify semantics exactly (#939)

The own-most descriptor decides: absent is safe, a non-callable data
value is an ordinary shadowing member and is safe, a callable data
value is rejected, and an accessor is rejected because it cannot be
inspected without invoking it. No daylight remains between the guard
and the serializer on this property.

* fix(storage): conform HTTP/PG backends to the post-#926 RuntimeStore interface (#943)

The chat cutover (#926) added deleteAllRuntime() to the RuntimeStore
contract while the HTTP and Postgres backends were developed in
parallel against the pre-#926 interface. Implements the method on both
backends (single-statement wipe on PG via the FK cascade; DELETE
/runtime on the HTTP contract, documented as an operator-gated
administrative endpoint), restoring a green typecheck and contract
suite on the integration branch.

* feat(runtime): injectable RuntimeStore backend + learner-key provider (#939 Part A) (#944)

* wip(runtime): backend injection seam — pending gate verification

* fix(runtime): cross-review hardening for the storage injection seam

- stage-deletion IndexedDB probe applies only to the default browser
  backend; an injected store always receives deleteStageRuntime
- explicit kv argument takes precedence over the configured learner-key
  provider, matching the store seam's explicit-beats-global rule
- configured learner-key resolution is latched with in-flight dedup,
  mirroring the store singleton; identity changes require app-level
  handling
- factory retry semantics documented; seal errors explain the
  module-level bootstrap requirement; isRuntimeStorageConfigured()
  probe and a test-only reset added
- client-bootstrap-only contract documented (SSR/HMR caveats)

* fix(runtime): snapshot configuration and make the test reset complete

- configureRuntimeStorage copies the option fields so mutating the
  caller's object after configuring cannot swap the sealed backend or
  identity provider
- resetRuntimeStorageForTests now clears every latched consumer cache
  (store singleton, learner-key in-flight promise) via a reset-hook
  registry, so a reset-then-reconfigure test actually gets the new
  backend

* fix(runtime): reset also clears the default learner-key caches

resetRuntimeStorageForTests left defaultInFlight/defaultKv latched, so
a default-path test could leak its anonymous key or KV store into the
next test despite the documented full-reset promise.

* feat(storage): runtime reference server — auth-derived learnerKey (#939 Part D) (#945)

* wip(storage): reference server — pending deleteAllRuntime route + gates

* feat(storage): runtime reference server — auth-derived learnerKey enforcement (#939 Part D)

- createRuntimeHttpHandler(store, options) wires the documented HTTP
  contract onto any injected RuntimeStore over node http
- authenticate is required; every learner-scoped operation verifies the
  path/body learnerKey against the authenticated principal (403
  FORBIDDEN_LEARNER) — the client-supplied value is never trusted
- mergeLearner requires an explicit authorizeMerge grant and admin
  surfaces (stage cascade, DELETE /runtime) require authorizeAdmin;
  both default-deny
- runnable reference entry demonstrates a pg Pool withTransaction and
  bearer-token authentication, marked as demo-only
- contract suite green through HttpRuntimeStore -> listening reference
  handler -> PgRuntimeStore(pglite); security matrix tested (401/403
  paths, admin default-deny); threat model documented

* fix(storage): cross-review hardening for the reference server (#939 Part D)

- principal learnerKey is optional: admin/merge-only credentials no
  longer fabricate learner identity; learner-scoped routes 403 without
  ownership
- full session/record envelopes pass the JSON-domain gate at the
  handler, so NUL/lone-surrogate identifiers map to 400 instead of 500
- payload validation follows the injected store's validator map
  (options.payloadValidators) instead of imposing DSL defaults
- reference factory accepts authenticate/authorizeMerge/authorizeAdmin/
  payloadValidators overrides; docs no longer claim the factory binds
  to localhost; demo-impersonation warning hardened
- 500 responses carry a generic message; details go to the server log
- ownership checks precede version checks and unowned sessions read as
  404, closing existence/version oracles; cross-learner denial matrix
  tested per route
- merge/delete concurrency documented as linearizable-equivalent with
  the ownership re-check narrowed to the delete call

* fix(storage): align reference-server semantics with the store contract

- future-stamped sessions read and delete through unchanged; 409
  FUTURE_VERSION applies only to guarded writes (status, append, merge)
- check-then-write races reclassify structurally via a post-failure
  re-fetch: missing session 404, non-active session 400, never a
  message-sniffed or generic 500

* fix(storage): close the reference CLI's pg pool on startup failure

ensureSchema opens connections inside createReferenceRuntimeServer, so
a failed schema init or occupied port left the pool holding database
resources until its idle timeout.

* fix(storage): close the records-route existence oracle

cosarah's review point on #946: the records list answered 200 [] for an
absent session but 404 for another learner's, so the 404 leaked that an
id exists. Absent and foreign sessions now answer identically (404
SESSION_NOT_FOUND) and the HTTP client maps that code back to an empty
list, preserving the store contract's absent-lists-as-empty semantics.
Contract doc records the server MAY/SHOULD and the client MUST.

bb8d4f30e7 feat(chat): add experimental Pi classroom runtime behind a flag (#914)
* feat(chat): add experimental Pi classroom runtime

* fix(chat): harden Pi whiteboard action sequencing

* fix(chat): retire actions on session errors

* fix(chat): close Pi runtime lifecycle gaps

* fix(chat): expose whiteboard element/line ids and bound code-line context

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

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

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

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

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

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

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

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

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

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

* 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).

* 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.
