Input schema sha256:460b687b0f3e70aa3c110542fd1fbd20ec7212ef36ce40430cf857ee052ad006 · Output schema sha256:ee5ba5d32353bc2323f54d567299bba03282268f227fe15ef72e6c00cd6e93bd · 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 surface is level
• α = arctan μ is the angle that minimizes the pull
• P = μW / √(1+μ²) and N = W / (1+μ²)
• Not a prescribed angle, an incline, tipping, a wedge, a screw, or a belt
