Phase 3.1: Type Safety - Add bridge_types.py for shared type aliases (EventDict, PowerWatts, Timestamp, DeviceID) - Define protocols for callbacks and message parsers - Strict type annotations on all core modules (session_detector, event_queue, device_manager) - Fix Optional handling and type guards throughout codebase - Achieve full mypy compliance: 0 errors across 47 source files Phase 3.2: Logging Unification - Migrate from stdlib logging to pure structlog across all runtime modules - Convert all logs to structured event+fields format (snake_case event names) - Remove f-string and printf-style logger calls - Add contextvars support for per-request correlation - Implement FastAPI middleware to bind request_id, http_method, http_path - Propagate X-Request-ID header in responses - Remove stdlib logging imports except setup layer (utils/logging.py) - Ensure log-level consistency across all modules Files Modified: - iot_bridge/bridge_types.py (new) - Central type definitions - iot_bridge/core/* - Type safety and logging unification - iot_bridge/clients/* - Structured logging with request context - iot_bridge/parsers/* - Type-safe parsing with structured logs - iot_bridge/utils/logging.py - Pure structlog setup with contextvars - iot_bridge/api/server.py - Added request correlation middleware - iot_bridge/tests/* - Test fixtures updated for type safety - iot_bridge/OPTIMIZATION_PLAN.md - Phase 3 status updated Validation: - mypy . → 0 errors (47 files) - All unit tests pass - Runtime behavior unchanged - API response headers include X-Request-ID
