# Eval Attestation Receipt Composer

`POST /v1/tools/compose_eval_attestation_receipt`

## Request

- Base URL: `https://ainumbers.co`
- URL: `https://ainumbers.co/v1/tools/compose_eval_attestation_receipt`
- Auth: none declared

Hashes a third-party eval log (e.g. an Inspect AI transcript) and binds it into a receipt that a compiled Work Mandate (art-274) can reference. VERIFY-ONLY: never executes, re-runs, or re-scores the eval -- composes shipped §4 hash, §16 signature, and §20 anchor carriers around a digest the caller already produced. claim_strength is the weakest-link status across the eval log hash and the mandate reference, never inflated by one strong leg covering a missing other.

**Tool URL:** https://ainumbers.co/chaingraph/art-438-eval-attestation-receipt-composer.html
**AP2/Policy Mandate export:** yes
