SINGLE_PHASE_ONLY

Version 1 calculates steady single-phase liquid or entered-property gas only.

CONSTANT_ENTERED_PROPERTIES

Liquid properties and entered gas Z, temperature, molar mass, and viscosity are constant over the traverse.

ACCELERATION_EXCLUDED

Acceleration and diameter-transition minor losses are excluded and reported as zero.

MULTIPHASE_METHODS_BLOCKED

Multiphase correlations remain unavailable until controlled primary cases and benchmarks pass Gate C.

Included: steady single-phase liquid or gas, Darcy-Weisbach friction, Churchill friction factor, hydrostatic head, segmented MD/TVD, and a top or bottom absolute-pressure boundary.

Excluded:multiphase holdup/regime, acceleration and transition losses, thermal coupling, transient flow assurance, and equipment acceptance. MULTIPHASE_METHODS_BLOCKED

Operational boundary: Auditable single-phase screening and planning aid only. It does not replace multiphase or transient simulation, flow-assurance analysis, equipment limits, operating procedures, or competent engineering review.
