B1 of the Matrix protocol-gaps roadmap, gate-green (688 tests): - StateEvent.RoomRetention + a shared utils/retention.ts (presets, isExpired, getRoomRetentionMs) with tests. - RoomRetention settings control (PL-gated preset buttons Off/1d/1w/1m) in Room Settings → General → Message Retention. - Timeline hides events past the room's max_lifetime (gated behind Show Hidden Events, like redactions) — messages visually disappear, losslessly. - Opt-in setting enforceRetentionLocally (default OFF) + a headless RetentionSweeper that permanently redacts the user's OWN expired messages (own-only, loaded-timeline scope, dedupe + retry). Nothing auto-deletes unless the user opts in. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
