# Runtime Observation System - Phase 1 Complete

I have successfully implemented the "Foundation" phase of the Runtime Observation System plan.

## 1. Core Observation Service
- **Created**: `e:\grid\safety\observability\runtime_observation.py`
- **Features**: 
  - `RuntimeObservationEvent` (Unified Event Schema)
  - `EventBus` (In-memory Pub/Sub for WebSocket bridging)
  - `RuntimeObservationService` (Bridges `SecurityLogger` -> `EventBus`)

## 2. Observation Endpoints
- **Created**: `e:\grid\safety\api\observation_endpoints.py`
- **Endpoints**:
  - `GET /observe/health`: System health status
  - `GET /observe/metrics`: Observation metrics (subscriber count)
  - `WS  /observe/stream`: Real-time WebSocket event stream

## 3. Middleware Integration
- **Updated**: `e:\grid\safety\api\middleware.py`
- **change**: Now logs critical security events directly to `security_logger`
  - Redis Infrastructure Failure (CRITICAL)
  - User Suspension (HIGH)
  - Rate Limiting (MEDIUM)
  - Pre-Check Block (HIGH)
- **Impact**: These events are now captured by `RuntimeObservationService` and streamed to WebSocket clients.

## 4. Main API Update
- **Updated**: `e:\grid\safety\api\main.py`
- **Change**: Registered `/observe` router with the FastAPI app.

## Next Steps (Phase 2)
1.  **Verify**: Test WebSocket connection with a client (e.g. `wscat`).
2.  **Enhance**: Implement Dynamic Rule Injection (`POST /observe/rules/dynamic`).
3.  **Correlate**: Add cross-module correlation logic to `security_monitoring.py`.
