feat: complete Event Log, Ledger, Memory, Cascade Router, Upgrade Queue, Activity Feed
This commit implements six major features:
1. Event Log System (src/swarm/event_log.py)
- SQLite-based audit trail for all swarm events
- Task lifecycle tracking (created, assigned, completed, failed)
- Agent lifecycle tracking (joined, left, status changes)
- Integrated with coordinator for automatic logging
- Dashboard page at /swarm/events
2. Lightning Ledger (src/lightning/ledger.py)
- Transaction tracking for Lightning Network payments
- Balance calculations (incoming, outgoing, net, available)
- Integrated with payment_handler for automatic logging
- Dashboard page at /lightning/ledger
3. Semantic Memory / Vector Store (src/memory/vector_store.py)
- Embedding-based similarity search for Echo agent
- Fallback to keyword matching if sentence-transformers unavailable
- Personal facts storage and retrieval
- Dashboard page at /memory
4. Cascade Router Integration (src/timmy/cascade_adapter.py)
- Automatic LLM failover between providers (Ollama → AirLLM → API)
- Circuit breaker pattern for failing providers
- Metrics tracking per provider (latency, error rates)
- Dashboard status page at /router/status
5. Self-Upgrade Approval Queue (src/upgrades/)
- State machine for self-modifications: proposed → approved/rejected → applied/failed
- Human approval required before applying changes
- Git integration for branch management
- Dashboard queue at /self-modify/queue
6. Real-Time Activity Feed (src/events/broadcaster.py)
- WebSocket-based live activity streaming
- Bridges event_log to dashboard clients
- Activity panel on /swarm/live
Tests:
- 101 unit tests passing
- 4 new E2E test files for Selenium testing
- Run with: SELENIUM_UI=1 pytest tests/functional/ -v --headed
Documentation:
- 6 ADRs (017-022) documenting architecture decisions
- Implementation summary in docs/IMPLEMENTATION_SUMMARY.md
- Architecture diagram in docs/architecture-v2.md
