RTC: Add base version tracking to prevent stale CRDT doc overwrites#77889
Conversation
Clients now embed a baseVersion in serialised _crdt_document meta values. The server rejects writes whose base version does not match the currently stored version, using an atomic compare-and-swap on the database row. On rejection the client refetches, merges the server's CRDT doc into the local Y.Doc, and retries. Autosave payloads no longer include _crdt_document to avoid sending stale copies.
