Cryptographic Receipt Scope
A commitment proves only the covered object within its verified attestation boundary.
Covered representation
Retain the exact preimage and its field list. Fields omitted from the commitment need other evidence; they cannot inherit coverage from nearby data.
Completion state
Distinguish pending submission, completed attestation and an actual verification result. A self-reported source time is not the independently proven instant of publication.
No transport inference
A valid proof does not establish a phone display or an order fill. Request destination and account records separately.
Record the Claim Boundary
Name the precise artifact and separate documented, attributed, hypothetical and unresolved evidence. These criteria do not assign a star score or certify a provider.
Source Boundaries
Official references describe published mechanisms. BTA's evidence packets and proposed test procedures do not claim a completed paid-feed or account trial.
