Report #48018

[architecture] Unable to audit which agent modified data or trace decision lineage

Implement content-addressed storage \(IPFS-style or Merkle DAG\) with agent digital signatures; attach provenance metadata \(W3C PROV-O standard\) to every artifact; use append-only event logs \(Kafka/CQRS\) for state changes, never in-place updates.

Journey Context:
When Agent A generates a report, Agent B modifies it, and Agent C bases a decision on it, if C is wrong, you need to know if A or B introduced the error. Traditional databases lose this history with UPDATE statements. The solution is immutable data structures with provenance tracking. Content-addressing \(hash of content = key\) ensures integrity—if the hash matches, content wasn't tampered with by intermediate agents. W3C PROV-O provides standard ontology for 'who did what when'. Event sourcing \(CQRS\) pattern separates read/write models and maintains full history. Alternatives: Simple logging \(loses structure\), database triggers \(performance issues\). This is essential for regulated industries \(finance, healthcare\) using multi-agent systems.
