Agent Messages Left an Offline Evidence Bundle
A policy-controlled verifier checks cross-organization agent events without trusting live services or one platform's logs.
Summary
A policy-controlled verifier checks cross-organization agent events without trusting live services or one platform's logs.
Each proposed bundle can include sender authentication, log commitments, witness-backed checkpoints, append-only continuity, delegation evidence and receiver-signed receipts when policy requires them. In a prototype covering 300 workflows and 1,200 valid bundles, all targeted corrupted or policy-insufficient bundles were rejected without a reported false acceptance. The verifier establishes evidence sufficiency under a chosen policy; it does not infer delivery or receipt merely from transport or log inclusion.
