Eval Attestation Receipt Composer
Hashes a third-party eval log (e.g. an Inspect AI transcript) and binds it into a receipt that a compiled Work Mandate can reference. VERIFY-ONLY: this tool never executes, re-runs, or re-scores the underlying eval; it composes shipped hash (§4), signature (§16), and anchor (§20) carriers around a digest you already produced.

🔒 All inputs are processed locally in your browser. No data is transmitted. Do not enter real personal data — use synthetic or anonymised inputs only.
Scope
Records that a specific eval-log digest exists and, optionally, that it is referenced by a compiled Work Mandate (art-274). Does not re-run, re-score, or grade the eval, and does not itself judge whether the eval satisfies the mandate's policy conditions.
Composition
Rides shipped carriers only: §4 execution_hash (this artifact), §16 Ed25519 signature (sign/verify buttons below), §20/§20.1 anchor binding (attach offline via the standard anchor pipeline; not exposed in this tool's UI).
