physics.fluid.pump

Three distinct suites: educational examples on the calculator page, this legacy regression count (16/16 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 2026-09-26.o2-o3. Calculation version 1.0.0. CVP 1.0.0-proposed. 4/4 golden · 9/9 CVP boundary · 10/10 invalid · 1/1 property · 1/1 metamorphic · 8/8 O3 · 2/2 cross-interface · 5/5 CVP contract. digest ce18e1b48677. O2: pump power/affinity vs a separate-module identity (≤2 ULP). Not orifice, not weir, not Manning, not Darcy, and not NPSH. ≤2 ULP vs O3 applies only to the published tabulated pump vectors. Not orifice, not weir, not Manning, not Darcy, and not NPSH.

• Golden (oracle-backed) 4 / 4
• CVP boundary 9 / 9
• Invalid input 10 / 10
• Property 1 / 1
• Metamorphic 1 / 1
• O3 high-precision 8 / 8
• Cross-interface 2 / 2
• CVP contract 5 / 5
• 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 Pump hydraulic/shaft power P_h=ρgQH, P=P_h/η, plus affinity laws, + O3 mpmath tabulated P.
• Assurance Engineering
• Deferred Not orifice, not weir, not Manning, not Darcy, and not NPSH.

• release artifacts aligned PASS
• schema output required declared PASS
• schema valid input executes PASS
• engine success output validates schema 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.

Assumptions

• Incompressible pump; P_h = ρ g Q H; P = P_h/η; default ρ=1000 kg/m³; η in (0, 1]
• Affinity: Q∝N D, H∝N² D², P∝N³ D³; geometrically similar; same fluid
• Not orifice, not weir, not Q=Av, not Darcy, not NPSH, not a catalog curve
