## Summary

Clarified that open+pong indicates healthy websocket transport and implemented observer channel-reconcile background flow so dashboard agent stays joined to all channels and receives realtime fanout.

**Approach:** Standard approach

## Key Decisions

### Treat connected+pong/no app events as observer membership scope issue
- **Chose:** Treat connected+pong/no app events as observer membership scope issue
- **Reasoning:** WebSocket transport is healthy when open and pong are present; missing message.created events indicates fanout scope mismatch (observer not joined to active channels or wrong workspace), not handshake/network failure.
