Report #79303

[architecture] Inability to trace which agents contributed to a final decision, preventing audit and debugging of multi-agent decisions

Attach W3C PROV provenance records to each inter-agent message: capture agent ID \(prov:wasAssociatedWith\), input entities \(prov:used\), output entity \(prov:generatedAtTime with timestamp\), and derivation chain \(prov:wasDerivedFrom\); store in graph database for traversal and blame assignment

Journey Context:
Without lineage, debugging is a 'black box': the final output is wrong but unclear which agent introduced the error or which input version was used. Simple logging lacks structure for complex derivation graphs \(Agent C uses outputs from A and B, which both depend on D\). W3C PROV provides a standard ontology for provenance: Entities \(data\), Activities \(agent executions\), and Agents. Each agent invocation is an Activity. Inputs/outputs are Entities with derivation relationships. This creates a directed acyclic graph enabling 'blame assignment': trace errors back to specific agent versions and inputs. Supports reproducibility: re-run with same inputs. Tradeoff: Payload size increases 30-50%, requires graph storage \(Neo4j, RDF store\). Essential for regulated industries \(finance, healthcare\) where audit trails are legally required.
