Verification

Legacy regression suite: 2/2 calculation tests · Production surface contract 6/6

Three distinct suites: educational examples on the calculator page, this legacy regression count (2/2 golden + boundary), and the CVP verification suite below. They are not the same number. Property, metamorphic, round-trip, O3, and interface statuses/checks are recorded in the CVP Manifest . SKIP (0/0) means that suite has no published vectors.

Input schema sha256:9ce3888c93dcbe001ca2550a7115e4e66e71059badd07d25ac6ceca4ec6aa993 · Output schema sha256:cbf8f128a0b5b78807d21d7ba15bf3a866bb079778d8a335e368aba0a5709f81 · 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.

Hibbeler, Mechanics of Materials — Deflection of beams — superposition
Supports: A wall-peak triangular load and a tip load on a cantilever superpose.

Aggregate outcomes, scope and artifact commitments are public. Complete test inputs, expected values, execution records and oracle infrastructure are retained privately. This summary does not independently reproduce the full verification run.
