onLoadDocument rebuilds a legacy page (page.content, no page.ydoc) into a Yjs
doc and seeds its 'title' fragment from the page.title column. Both
TiptapTransformer.toYdoc and buildTitleSeedYdoc mint fresh Yjs client-ids on
every call, so the heal must run exactly once per page. Three holes let it run
twice (or lose a write):
- Duplication trap: the initial page read took no row lock, so two processes
(the API process via openDirectConnection and the standalone collab process)
could both observe ydoc IS NULL and each rebuild with different client-ids; a
long-offline client merging an earlier rebuild then duplicates all content.
- Lost-update: persistYdoc wrote updatePage({ydoc}) outside any transaction, so
it could clobber a concurrent onStoreDocument write (which does take a lock).
- Swallowed write errors: a failed heal-persist was logged but the unpersisted
fresh-client-id doc was returned anyway, silently re-arming the trap.
Fix: the heal now runs in healUnderLock, which re-reads the row FOR UPDATE inside
one transaction and re-validates under the lock — if ydoc is now present it
adopts it (no rebuild, no write), otherwise it rebuilds, seeds, and persists the
ydoc in the SAME transaction. The healthy hot path still loads with no lock and
no write. Failure handling surfaces instead of hiding: a rebuild-persist failure
refuses the load (re-throw + error log) so an unpersisted rebuild is never handed
out, while a seed-only persist failure serves the existing healthy ydoc without
the unpersisted seed (non-fatal). Removed the non-transactional persistYdoc.
Deliberately does NOT use a fixed clientID: identical client-ids across docs
built from differing content violate Yjs per-actor uniqueness and corrupt worse
than the trap; serialization under the row lock is the correct fix.

Title now lives in the page's Yjs 'title' fragment, but two paths corrupted it:
- Rename-revert: a REST/MCP title change wrote only the page.title column,
never the Yjs fragment, so the next editor open replayed the stale Yjs title
and reverted the rename. PageService.update now mirrors the new title into the
Yjs 'title' fragment via CollaborationGateway.writePageTitle, which goes
through openDirectConnection directly (Redis-independent: works with
COLLAB_DISABLE_REDIS and in single-process deployments, unlike the
Redis-routed handleYjsEvent path). The write is best-effort: a Yjs failure is
logged and never rolls back the committed column write. Agent provenance
(actor/aiChatId) is threaded into the store context.
- Untitled-on-open: an empty/just-initialized 'title' fragment clobbered a
non-empty page.title to '' on open. onStoreDocument now treats the title as
changed only when the extracted text is non-empty, covering both the
title-only and body+title save branches. Empty-retitling via collab is
intentionally impossible; the REST DTO is the place to enforce non-empty.
writeTitleFragment does a full clear+seed of the 'title' fragment (no
duplication/concatenation) and leaves the body fragment intact. Removed the dead
useTreeMutation.handleRename path. Adds unit tests for writeTitleFragment, the
gateway write, the anti-empty-clobber guard, and agent provenance.

Adds the unit tests called out in the PR #120 review (test-coverage
aspect). No production logic changes — the only non-test edit is exporting
the already-injectable warmInfiniteAll helper so it can be unit tested.
Server (Jest):
- persistence.extension.spec.ts: onStoreDocument classification matrix
(no-op / title-only / body+title / body-only), onLoadDocument seed +
persist gating (early-return, page-null, ydoc seed, already-seeded
no-persist, legacy content->ydoc), and seedTitleFragment 4-branch guard.
- collaboration.util.spec.ts: buildTitleSeedYdoc round-trip.
- environment.service.spec.ts: getCorsAllowedOrigins / isSwaggerEnabled.
- auth.controller.spec.ts: login returnToken opt-in branch.
Client (Vitest):
- query-persister.test.ts: shouldDehydrateOfflineQuery status + allowlist
gates and OFFLINE_PERSIST_ROOTS membership.
- is-capacitor.test.ts: isCapacitorNativePlatform platform detection.
- make-offline.test.ts: warmInfiniteAll cursor walk / maxPages / error
swallow, and warmPageYdoc settle-once + timeout + teardown.
