Public tool · read-only

Recompute the receipt's canonical sha256 hash and check its signature. A changed body,
hash, or signature fails verification. This tool never spends funds, invokes a provider, or mutates
platform state.

Any paid invocation stays outside this verifier and must use a separately authorized live execution
rail with platform budget, policy, trust, and owner gates. Public trust vocabulary remains
verified, reachable, and failed.
