Input schema sha256:3188bc0053ad99397a9771e6ecf4805d543f4c41cb484956ebdc4a7af11f4033 · Output schema sha256:a162bce9167360ca188c47f7950769ee1feef5e3b790a30af72b144fb20cd141 · 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.

Limitations

  • Ix and Iy are supplied about each part centroid
  • Axes stay parallel to x and y
  • Negative area is a hole
  • Total area must not be zero
  • Not product of inertia, principal axes, section modulus, or beam deflection
