Report #98503

[architecture] No one knows which agent produced a bad output in a chain

Attach a provenance record to every handoff with agent identity, version, timestamp, input hash, and output hash. Thread this through trace context or a signed envelope so it is auditable end-to-end.

Journey Context:
In long chains, debugging feels like 'it came from somewhere upstream.' Tutorials skip lineage because it looks like overhead. Without it you cannot do root-cause analysis, rollback, or accountability. The lightweight version is a provenance field on every message; the robust version signs it. The cost is a few hundred bytes per message; the value is hours saved during incidents and a clear audit trail.
