The collaboration server becomes the writer of page state (ADR 0003,
realtime-collaboration.md §lifecycle):
- onLoadDocument reconstructs a page's Y.Doc from PostgreSQL by applying
`pages.ydoc_state` and then every `page_updates` row in order, so a page
with a long update log loads correctly.
- onStoreDocument persists debounced (2 s, max 30 s): it appends the delta
since the last flush to `page_updates`, periodically merges the log back
into `ydoc_state` (inline threshold; the session-aware compaction of idle
pages remains the separate job, #40), refreshes `page_content_cache`
(plain text / Markdown / HTML / outline via the shared derivation, #24),
bumps `pages.updated_at`, and keeps `Attachment.pageId` pointed at the
embedding page (#31). Each flush runs in one transaction and its duration
is logged.
- The document size ceiling (MAX_PAGE_DOCUMENT_BYTES) is enforced on store:
an oversize document is not persisted and the clients are notified with a
stateless error so they can revert.
Persistence is an injected port (PagePersistence): the Postgres
implementation is covered by a DB-backed test (store/load round-trip,
content-cache refresh, a 1000-entry update log, size-ceiling rejection,
not-found), and the hook wiring — two-client sync, survival across a server
restart, and the size-ceiling stateless notification — by an integration
test using an in-memory fake. The collab package gains its own vitest setup
that provisions an isolated `_collab` test database.
The REST `PUT /pages/:id/state` write path stays in place for now and is
retired (410) together with switching the editor to live collaboration in
#36, so the deployed editor is never left unable to save between the two
deploys.

The api mints a short-lived (60 s) HS256 JWT per page open after an interim
permission check; the collab server authenticates every connection with it
(ADR 0003/0007 — the only JWTs in the system).
- packages/shared: browser-safe token schema/types in `collab-token`, and the
Node `crypto` sign/verify in `token-crypto` behind its own subpath export
(`@dorfteich/shared/token-crypto`) so the web bundle never pulls in
`node:crypto`. Only HS256 is produced/accepted; the signature is checked in
constant time before any untrusted field is read.
- api: `GET /pages/:id/collab-token` (auth-required) returns
{token, mode, expiresInSeconds}; `mode` is rw/ro via the interim access
service; issuance is logged at debug level without the token value.
- collab: `onAuthenticate` verifies the token, checks the pageId matches the
document name, stores {userId, mode} context, and enforces `ro` via
Hocuspocus' read-only connection flag. Hocuspocus' own signal handling is
disabled so index.ts remains the single shutdown owner.
- Shared COLLAB_TOKEN_SECRET env for api + collab (compose, dev overlay,
.env.example, stage docs); a dev default keeps native dev/test/CI running.
Tests: shared token round-trip/rejection; api endpoint e2e (auth required,
claims, 404 for non-members/unknown ids); collab integration via
HocuspocusProvider (valid token connects; expired/tampered/mismatched-page/
wrong-secret rejected; read-only writes dropped, verified with two clients).

Bootstrap apps/collab as a Hocuspocus WebSocket server (ADR 0003):
- pino JSON logging (service=collab) and shared Zod env validation
(collabEnvSchema); structured connection open/close logs.
- /healthz endpoint (process liveness + PostgreSQL ping) served via the
onRequest hook, matching the container-internal path and the proxied
/collab/healthz path; any WebSocket handshake is accepted for now
(authentication arrives with #34, persistence with #35).
- Dockerfile (ESM workspace build) and a compose service on the frontend
and internal networks with a healthcheck; dev overlay service and a new
COLLAB_PORT variable.
- CD builds, pushes, and promotes the collab image; CI builds it on PRs;
the smoke suite asserts /collab/healthz through the reverse proxy.
- deployment.md/stages.md: proxy routing, per-stage COLLAB_PORT, checklist.
Closes#33

pnpm workspace with apps/web, apps/api, apps/collab, and
packages/shared; strict TypeScript base config, repo-wide ESLint (flat)
+ Prettier, Vitest per package, and root scripts lint/typecheck/test/
build. @dorfteich/shared ships a first health-response helper consumed
by apps/api to prove workspace linking. Existing markdown docs are
reformatted once by the new Prettier setup.
Closes#1
