A new package, packages/server: Hocuspocus 3.4.4 on /sync, a project a document, refused with a reason when the store has not got it; every update stored in Postgres as it comes and compacted after 500 updates, a minute of quiet and when the last person leaves (FOR UPDATE on the row written when the project is made); the janitor runs only here, at loading and 250 ms after a change that is not its own; readers change nothing; /healthz; JSON log. On closing it takes no one new and closes the sockets too (Hocuspocus' close is a message after which a client signs in again on the same socket). The tests use real clients against a throwaway Postgres in Docker. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
