AsyncEventBridge bridges sync EventEmitter to asyncio consumers. FastAPI app with session management, discussion control, roles/providers. WebSocket for real-time events + inject, SSE for read-only streaming. Minimal dark-theme HTML/JS UI. `meeting-room serve` CLI subcommand. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

# v2-p2-async-bridge
|
|
|
|
## Goal
|
|
Bridge synchronous EventEmitter to asyncio so DiscussionEngine can run in a thread while WebSocket/SSE consumers receive events asynchronously.
|
|
|
|
## Key files
|
|
- `meeting_room/events.py` — add AsyncEventBridge class
|
|
- `meeting_room/engine.py` — no changes (runs in thread as-is)
|
|
|
|
## Decisions log
|
|
- 2026-05-04: AsyncEventBridge + asyncio.to_thread() chosen over async engine rewrite. Minimizes changes, engine stays sync.
|
|
|
|
## Open questions
|
|
- [ ] None
|
|
|
|
## Completed steps
|
|
- [x] AsyncEventBridge class in events.py
|
|
- [x] Thread-safe bridge with call_soon_threadsafe
|
|
- [x] subscribe/unsubscribe consumer queues
|
|
- [x] Drop policy on full queues
|
|
- [x] Tests (10/10 passing)
|
|
|
|
## Notes
|
|
- events.py already has comment: "In Phase 2, an AsyncEventBridge will forward events to WebSocket clients"
|
|
- Bridge subscribes to sync EventEmitter, puts events into asyncio.Queue
|
|
- Consumers (WebSocket handlers, SSE handlers) read from the queue |
