physics.fluid.valve_cv

O2: valve Kv/Cv vs a separate-module identity (≤2 ULP). Not a venturi wrap, not an orifice, and not Q=Av. ≤2 ULP vs O3 applies only to the published tabulated venturi vectors. Not Q=Av, not Manning, and not Darcy.

This summary records the outcome of the verification run. The full test corpus, oracle implementations, reference tables and generators are retained privately. Their digests identify those artifacts; a digest alone does not let a reader independently reproduce the full verification run.

Use the capability's public input schema and examples to call the versioned REST API or MCP. These interfaces remain available without downloading the validation infrastructure. A successful example checks that example; it does not establish that the complete private suite has been independently reproduced.
