Report #77972

[architecture] Cannot debug which agent modified data or where a failure originated in long chains

Propagate W3C Trace Context headers \(traceparent, tracestate\) across all agent boundaries. Include agent-id and request-id in baggage. Ensure all logs include trace-id for distributed tracing. Use this to reconstruct exact agent provenance for audit and debugging of multi-step workflows.

Journey Context:
Without distributed tracing, debugging multi-agent failures is impossible. Each agent looks like a black box. Trace Context is the W3C standard supported by OpenTelemetry, Jaeger, etc. The baggage field carries domain-specific context like 'original-user-id' that survives the chain. Alternative is custom header propagation, but standard ensures interoperability with observability platforms and avoids vendor lock-in.
