Input schema sha256:89e577b985d3bbc116f749d3134f8f6ed7f963d885942ee33050c066b3189b5c · Output schema sha256:fcab92dc6c909617906be23dc4edfc9ff24242fb87ee421460fb70a9a773c82b · 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

  • Simply supported span
  • Point forces and concentrated moments only
  • Upward force and CCW moment are positive
  • A load exactly at the cut stays on the right
  • Not distributed load, deflection, or an indeterminate beam
