Six WS sites that previously broadcast presence_update to spaces only now use
collectProfileBroadcastTargetIds (the same recipient set as user_updated):
- ws/handler.ts finalizeDisconnect (offline)
- ws/handler.ts auth path (online)
- ws/events.ts handlePresenceUpdate (manual idle/dnd/online)
- ws/events.ts handleActivityUpdate (rich activity changes)
- routes/users.ts showActivity-toggle clear
- routes/users.ts status PATCH
Friends with no shared space + DM-only co-members now see each other's
online/offline transitions live, matching user_updated semantics. Federated
stub presence broadcasts (Task B3) use the same helper, so cross-instance
recipients are uniform.
Updates one assertion in social.federated.test.ts that asserted the old
snowflake-style stub username (now realname-based per A1).
