O2: ISO 5167-4 classical Venturi Q=C E A2 √(2Δp/ρ), C from convergent type vs a separate-module identity (≤2 ULP). Not given C_d, not ISA 1932, not RHG orifice, not Q=Av, and not Darcy. ≤2 ULP vs O3 applies only to the published tabulated ISO-venturi vectors. Not given C_d, not ISA 1932, not RHG orifice, and not Q=Av.

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.
