Comprehensive analysis of the race condition where users in the same
Reflector room can end up in different Daily.co rooms.
Contents:
- Problem statement and symptoms
- Evidence from Hypothesis simulation
- Current system analysis with code references
- Detailed race condition timeline
- Why current mitigations (Daily API, fallback) are insufficient
- Three solution options with trade-offs
- Recommended approach: Track "intent to join" via /joining endpoint
- Implementation checklist and file references
Key insight: The race is a data model gap, not a timing issue. Backend
needs explicit knowledge of joining users before Daily presence API
sees them.
* fix websocket tests
* fix: restore timeout and fix celery test infrastructure
- Re-add timeout=1.0 to ws_manager pubsub loop (prevents CPU spin?)
- Use Redis for Celery tests (memory:// broker doesn't support chords)
- Add timeout param to in-memory subscriber mock
- Remove duplicate celery_includes fixture from rtc_ws tests
* fix: remove redundant inline imports in test files
* fix: update gitleaks ignore for moved s3_key line

Set duration early in get_participants from Daily API (seconds -> ms),
ensuring post_zulip has the value before mixdown_tracks completes.
Removes redundant duration update from mixdown_tracks.

Topic detection was timing out on longer transcripts when LLM
responses are slow. This affects detect_chunk_topic and other
LLM-calling tasks that use TIMEOUT_MEDIUM.

Also trigger poll_daily_room_presence_task when user joins meeting via
/join endpoint, not just on /leave. Webhooks can fail or not exist
(e.g., Whereby has no participant.joined webhook), so frontend-triggered
polls needed for both join and leave events.
Backend:
- Add POST /rooms/{room_name}/meetings/{meeting_id}/leave endpoint
- Triggers poll_daily_room_presence_task immediately on user disconnect
- Reduces detection latency from 0-30s (periodic poll) to ~1-2s
Frontend:
- Add useRoomLeaveMeeting() mutation hook
- Add beforeunload handler in DailyRoom that calls sendBeacon()
- Guarantees API call completion even if tab closes mid-request
Context:
- Daily.co webhooks handle clean disconnects
- This endpoint handles dirty disconnects (tab close, crash, network drop)
- Redis lock prevents spam if multiple users leave simultaneously
This commit is no-mistaken and follows user requirements for readonly research
task that was later approved for implementation.
* set hatchet as default for multitracks
* fix: pipeline routing tests for hatchet-default branch
- Create room with use_celery=True to force Celery backend in tests
- Link transcript to room to enable multitrack pipeline routing
- Fixes test failures caused by missing HATCHET_CLIENT_TOKEN in test env
* Update server/reflector/services/transcript_process.py

* progress track for some hatchet tasks
* remove inline imports / type fixes
* progress callback for mixdown - move to a function
