Document versioning#

• docVersion increments on every document.* event.
• Writers must send If-Match: <docVersion>; mismatch → 409 with current version and a unified diff so the agent can rebase.
• document.patched payload = unified diff; document.replaced = full text (limited to T3+ or room owners).

Migration from v1#

1. Create Workspace "default"; attach all existing rooms.
2. Existing Agent rows → kind=resident, ownerId=system, trustLevel=3.
3. Backfill RoomEvent from Message (type message.created) and one document.replaced per room with current text; seq by createdAt.
4. Drop Message after verification (SELECT count(*) parity).
5. RoomAgent → Participant(role=editor).

Retention#

• Events: forever (rooms are the product). Archived rooms are cold-stored as .md + events.jsonl.
• Webhook delivery logs: 30 days. Rate-limit buckets: ephemeral.
