mechanical.beam.deflection

Three distinct suites: educational examples on the calculator page, this legacy regression count (7/7 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.parent.v11.ri. Calculation version 1.1.0. CVP 1.0.0-proposed. 5/5 golden · 2/2 CVP boundary · 6/6 invalid · 5/5 property · 1/1 metamorphic · 24/24 O3 · 2/2 cross-interface · 2/2 cross-calculator · 6/6 CVP contract. digest 3f54eaf621a9. O2: delta vs composed Layer-A separate-module identities (≤2 ULP). Multi-load is Σ δ_i. Not FEM, not indeterminate, not generic multi-load max. ≤2 ULP vs O3 applies only to tabulated Layer-A partitions projected from published leaf mpmath tables (simply_supported×point×midspan, cantilever×point×tip, simply_supported×uniform×midspan). Multi-load composition is out of O3 claim scope.

• Golden (oracle-backed) 5 / 5
• CVP boundary 2 / 2
• Invalid input 6 / 6
• Property 5 / 5
• Metamorphic 1 / 1
• O3 high-precision 24 / 24
• Cross-interface 2 / 2
• Cross-calculator 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. SSR Entry uses leaf-shaped query (prefill remap). REST/MCP use mechanical.beam.deflection contract inputs.
• Verified scope Shared Euler–Bernoulli contract: support × loads[] × query; Layer-A closed forms via delegates; multi-load δ=Σδ_i; partitioned O3 for three Layer-A tip/midspan tables. v1.1 adds overhang, cantilever triangular, partial/outer uniform, center/ends triangle peaks.
• Assurance Engineering
• Deferred Not FEM, not indeterminate, not Timoshenko, not generic multi-load max, not interior uniform segments, not overhang arm at_x stations.

• 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.
