Implement Request/Response Logging with Correlation IDs #31
Description
Description
No request correlation IDs. When debugging issues across multiple services, impossible to trace a single request through the system.
Current State
Basic Winston logging without correlation.
Problems
- Cannot trace requests across services
- Hard to debug multi-step flows
- No request/response logging
- No log aggregation
Proposed Solution
Add correlation IDs to all requests and structured logging.
Acceptance Criteria
- X-Request-ID header generated for all requests
- Correlation ID propagated to all logs
- Request/response logging middleware
- Structured JSON logging
- Log levels configurable per environment
- Sensitive data redaction (tokens, keys)
- Log aggregation (Datadog, CloudWatch, etc.)
