AI Evidence Envelope Verifier
The verifier replays a downloaded Disclosure Checker, AI Production Stack Preflight or Decision Provenance envelope using the current deterministic ruleset. It checks recorded inputs, decision identifiers, evidence digests and product-availability boundaries. A successful replay establishes internal consistency with the supplied file. It does not authenticate the author, reviewer, external evidence or timestamp.
Browser-only replay
Verify an evidence envelope
The JSON stays in this browser. Disclara does not send the selected file to an API or store its contents.
Supported now: checker evidence disclara.check.v23, Production Stack Preflight disclara.production-stack-preflight.v1 and Decision Provenance disclara.decision-provenance.v1. For a candidate-bound image comparison, use the exact-file provenance replay. Older checker versions need their matching verifier.
Need an envelope to verify?
Run the disclosure checker, Production Stack Preflight or Decision Provenance Builder and download the JSON from its result.
What the result means
Verified
The current evaluator reproduces every recorded decision from the envelope’s supported input and timestamp.
Inconsistent
A required field is invalid or at least one identifier, digest or decision differs from deterministic replay.
Unsupported
The file names a schema, ruleset or evaluator that this release cannot safely replay. No validity is inferred.
Applies when
- You received JSON downloaded from the Disclosure Checker, Production Stack Preflight or Decision Provenance Builder.
- You need to check whether its recorded decision is reproducible.
- You want to identify a changed context, policy input, digest, availability boundary or result field.
Doesn’t establish
- Who created or approved the envelope.
- That the timestamp came from a trusted timestamp authority.
- That an asset, consent record or platform capture is authentic.
