What this verifier checks Tap to expand

Profiles: VC JSON, VC-JWT, Compact Proof JWT, Local W3C Package, and Raw Technical JSON.

Checks: reads the file locally, extracts the receipt story, checks visible hashes, verifies P-256 / ES256 signatures when the required public key, signature, and signed payload are disclosed, checks the offline SYNC Foundry Registry for enrolled signing authorities, and creates a reviewer-friendly authentication packet.
