Nothing ever removed an indexed row: redacted messages stayed searchable with full plaintext and rendered as normal results. Now: a client-level RoomEvent.Redaction listener deletes the row, leave/ban clears the room (clearRoom finally has a caller), m.replace edits upsert the original row instead of indexing the "* fallback" separately, and cached rows whose local event is redacted render through the existing redacted_because placeholder. Unit-tested. Fixes #14 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01PPmy3tPq869XDW4njjVaKA
