Verification

Legacy regression suite: 3/3 calculation tests · Production surface contract 6/6

Three distinct suites: educational examples on the calculator page, this legacy regression count (3/3 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 2026-10-28.meta-metrics-v2. Calculation version 1.0.0. CVP 1.0.0-proposed. 1/1 golden · 1/1 CVP boundary · 1/1 invalid · 1/1 property · 2/2 metamorphic · 1/1 cross-interface · 6/6 CVP contract. digest 889442d20854.

  • Golden (oracle-backed) 1 / 1
  • CVP boundary 1 / 1
  • Invalid input 1 / 1
  • Property 1 / 1

  • Cross-interface 1 / 1
  • CVP contract 6 / 6
  • Interfaces PASS · UI (SSR) / REST / MCP
  • Interface claim ui-ssr is query-result HTML, not a live browser session.
  • Assurance Engineering
  • 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

Input schema sha256:1141acfd20a90c55f99d0713bc0d819ec65f575dd02928a78ee3e1bc44e8e2cf · Output schema sha256:d83168b8638ef74edc78a8b8161fc3b6a3af12936781682be71c575551ff4585 · 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.

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.
