Verification

Legacy regression suite: 5/5 calculation tests · Production surface contract 6/6

Three distinct suites: educational examples on the calculator page, this legacy regression count (5/5 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.

CVP verification suite

Protocol checks from the Evidence Manifest. Distinct from the legacy regression suite above. Verification revision 2026-09-27.o2-o3. Calculation version 1.0.0. CVP 1.0.0-proposed. 4/4 golden · 3/3 CVP boundary · 5/5 invalid · 1/1 property · 1/1 metamorphic · 8/8 O3 · 2/2 cross-interface · 6/6 CVP contract. digest d05ea939323d. O2: tau vs a separate-module identity (≤2 ULP). Not a rectangle from b·h, not a circle, and not beam deflection. ≤2 ULP vs O3 applies only to the published tabulated transverse-shear vectors.

  • Golden (oracle-backed) 4 / 4
  • CVP boundary 3 / 3
  • Invalid input 5 / 5
  • Property 1 / 1
  • Metamorphic 1 / 1
  • O3 high-precision 8 / 8
  • Cross-interface 2 / 2
  • CVP contract 6 / 6
  • Interfaces PASS · UI (SSR) / REST / MCP
  • Interface claim ui-ssr is query-result HTML, not a live browser session. Error-path engine·REST·MCP 1/1 (status, code, calculation_version). SSR compared on URL-canonical requested calculations; empty query is idle (not an error) and JSON-typed object/array inputs are REST/MCP-only.
  • Verified scope τ = VQ/(I b) (Jourawski); + O3 mpmath tabulated τ.
  • Assurance Engineering
  • Deferred Not a rectangle from b·h, not a circle, and not beam deflection.
  • release artifacts aligned PASS
  • schema output required declared PASS
  • schema valid input executes PASS
  • engine success output validates schema PASS
  • schema rejects incomplete input PASS
  • rest success payload validates schema PASS

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.

Verification disclosure

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.
