vLEI / ACDC SAID Structural Checker

Scope fence – read before use Structural check – verifies the credential's internal self-addressing integrity, NOT the KERI chain of trust, NOT issuer authority, NOT revocation state. This tool recomputes SAIDs over the pasted JSON and cross-checks the declared schema SAID against a small pinned table – it never resolves a KERI key event log, never contacts a witness or watcher, and never checks whether the issuing AID is authorized to issue this credential type. Chain (edge) fields are displayed with their digests, not verified. A passing result means the credential is internally self-consistent and well-formed – it is not GLEIF-grade verification, and a reader who assumes otherwise has been misled by us.
