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.
