Report #104048

[architecture] Agents exchange outputs without provenance, making it impossible to audit what caused a bad decision

Attach lineage metadata to every message: originating prompt, model version, temperature/top-p settings, tool calls invoked, retrieved context IDs, and prior message IDs. Store this in an append-only log keyed by workflow idempotency key. Design every output to be reproducible or at least explainable from its lineage record.

Journey Context:
When a multi-agent system goes wrong, the first question is 'which agent, with which context, produced this output?' Teams often log only the final answer, losing the trail. The fix is treating every inter-agent message as a provenance record, not just data. This does not mean storing every token; it means storing the deterministic inputs \(prompt template IDs, retrieval results, parameters\) and references. The tradeoff is storage and log complexity, but it is non-negotiable for debugging, compliance, and continuous improvement. Without lineage you cannot fix root causes, only symptoms.
