Report #66264

[architecture] Inability to audit which agent or model version produced specific data in a chain, leading to repudiation risks

Issue W3C Verifiable Credentials for each agent execution, embedding the model hash, prompt fingerprint, and output hash; chain these credentials to create an immutable cryptographic audit trail.

Journey Context:
In regulated environments such as finance or healthcare, stating that Agent B said X is insufficient provenance; cryptographic proof is required of who ran what model on which input. Verifiable Credentials provide tamper-evident attestations that can be selectively disclosed. Alternatives such as simple logs are forgeable, while blockchain adds unnecessary overhead. The tradeoff is that VC issuance and verification add latency; the system requires key management infrastructure for Decentralized Identifiers; and credential revocation is complex if a model is later deemed compromised, requiring short-lived credentials or revocation lists.
