mechanical.statics.cantilever_partial_at_deflection

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 2026-09-27.o2-o3. Calculation version 1.0.0. CVP 1.0.0-proposed. 4/4 golden · 1/1 CVP boundary · 3/3 invalid · 1/1 property · 1/1 metamorphic · 8/8 O3 · 2/2 cross-interface · 6/6 CVP contract. digest 2d14a7239c1d. O2: delta vs a separate-module identity (≤2 ULP). Not tip-only under the same partial load, and not a simply supported span. ≤2 ULP vs O3 applies only to the published tabulated cantilever-partial-at vectors.

• Golden (oracle-backed) 4 / 4
• CVP boundary 1 / 1
• Invalid input 3 / 3
• 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 cantilever partial uniform at station (two-piece); + O3 mpmath tabulated δ.
• Assurance Engineering
• Deferred Not tip-only under the same partial load, and not a simply supported span.

• 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

Input schema sha256:bdbe1f96d276bd27d6dab367a72218496ce45d5be583a8f289aa07756ea6b38a · Output schema sha256:c1143f42ed539b58fcedc996b026c6d6cc83ed134bbfd8877ba233ed37dd11f0 · 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.
