Report #28798

[architecture] Unable to audit which upstream agent or prompt version caused a downstream error in complex chains

Propagate agent attribution data \(agent\_id, prompt\_version, input\_hash\) using OpenTelemetry Baggage and Span attributes across all agent boundaries, ensuring every downstream span carries the full provenance chain for root cause analysis

Journey Context:
When Agent C produces an error, teams can't tell if it was bad input from Agent A or a transformation error in Agent B. Standard logging loses context across async boundaries. OpenTelemetry traces show timing but not semantic attribution \(which prompt version\). The solution requires using Baggage \(context propagation\) to carry immutable identifiers across process boundaries, combined with Span attributes for local context. Alternatives like passing metadata in the message body requires schema changes. The fix integrates with existing observability standards.
