What this receipt does not verify
An external system reference was confirmed for this action. The confirmation covers the reference's existence and metadata, not the quality or correctness of the action. Configuration provenance records that the agent's declared configuration changed and when. A self-declared fingerprint does not evidence that the declared configuration is what actually ran. Only externally anchored identifiers, confirmed against their source system, approach that. Proofroom does not certify that the agent is accurate, unbiased or legally sound. Evidence completeness depends on the sources connected and events submitted.
