Align frontend and backend error observability with correlation IDs and structured telemetry for distributed tracing across systems. Backend changes: - Add CorrelationIdMiddleware to generate/extract correlation IDs - Include correlation_id in all ErrorResponse objects - Store correlation ID in structlog contextvars for automatic inclusion in logs - Add correlation ID to response headers (X-Correlation-ID) Frontend changes: - API client automatically generates session-scoped UUID4 and includes X-Correlation-ID header in all requests - Extract correlation ID from API error responses - Update error handlers to use telemetry with correlation IDs - Add telemetry logging to ErrorBoundary, PageErrorBoundary, SectionErrorBoundary - Implement redaction utilities for privacy-safe logging of sensitive data Documentation: - Add observability guidelines to Web-Development.md * Correlation ID usage patterns * Privacy & security best practices * Telemetry event structure * Redaction utilities for sensitive data - Add distributed tracing architecture section to Architecture.md * Correlation ID flow across frontend/backend * Example troubleshooting scenario * Implementation details for future enhancements Testing: - Add comprehensive tests for correlation middleware - Update error boundary tests to verify telemetry integration - Verify TypeScript and ESLint pass with no warnings Fixes: Issue #40 - Frontend and backend observability are not aligned Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

## 40) Frontend and backend observability are not aligned
|
|
- Where found:
|
|
- [backend/app/main.py](backend/app/main.py)
|
|
- [frontend/src](frontend/src)
|
|
- Why this is needed:
|
|
- Backend uses structured logging while frontend error telemetry is mostly local and ad-hoc.
|
|
- Goal:
|
|
- Define unified error telemetry and correlation approach.
|
|
- What to do:
|
|
- Introduce frontend error reporting pipeline and request correlation IDs.
|
|
- Possible traps and issues:
|
|
- PII/sensitive payload leakage risk in client-side telemetry.
|
|
- Docs changes needed:
|
|
- Add observability and privacy-safe logging guidelines.
|

- Doc references:
