Public receipt verification and assurance evidence. One governed runtime underneath; a domain-native workbench above it. Observed evidence, modeled analysis, human authority, and audit receipts remain separate states.

Verify a receipt
Open the existing verifier to paste a receipt and a public key. Offline checks run in your browser. Online checks require a separate explicit action.
Trust scope: a supplied public key proves only the check against that key. Runtime keys are REPO_DECLARED until pinned out of band. Independent validation: UNKNOWN. Receipt integrity does not prove output truth, signer authority, authorization, admission, approval, or production readiness.
