Input schema sha256:f845c10abdc750ce13ac6aca11bed4723cfb4ce3a4d1b434a98a0ef4aed2daa5 · Output schema sha256:dc0f59724671d8d57a6bead540a247dc701501b99c351aaebfd7f15b88550391 · Build-time SHA-256 digests prove published artifacts agree with each other (release_integrity.scope=workspace). Production attestation GETs canonical URLs twice (public/cached view and origin), including Capability HTML, via npm run attest:production --write (published at /.well-known/calculatorx-production-attestation.json) and fails if the public Capability page advertises a different calculation_version. This is artifact consistency, not an independent immutable release log.
