logging-error-handling

To prevent PII redaction failures, enforce “exclude at the call site” rules so secrets and personal data never enter log streams, rather than relying on downstream scrubbing filters.

RFC 7807 standardizes API error responses, allowing services to return structured problem details without exposing internal system errors or sensitive stack traces to clients.

Propagate correlation IDs and W3C trace context by injecting traceparent headers into inbound HTTP, async queue payloads, and scheduled job metadata for end-to-end distributed tracing.

Use an explicit error taxonomy to separate User, System, ThirdParty, and Security errors, applying distinct log levels and audit behaviors for faster incident diagnosis.

Write append-only audit logs for security-relevant events to maintain an immutable record of access and changes, satisfying compliance and security investigation requirements.

Yes, this structured logging and error handling design spans outbound external calls, ensuring trace propagation and sensitive-data protection across all distributed system boundaries.
