Input schema sha256:014dd65bc33d21b3a7abf8233bebbf36b1e20166412c12eebf508f6ab7e17272 · Output schema sha256:bd1941a7bd65f2a1b877a2423ac76a3799ef6a08685bb6e693942707e5330aad · 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

  • The block is a homogeneous rectangle
  • The only force is its own weight
  • b is the base along the incline and h is the height perpendicular to it
  • Not a horizontal force on a level surface, a wedge, a screw, or a belt
