provisional_second_order,241200,0.88064076,0.900000,1.4,pre-adjustment operating point,"Retained project development log, July 2026","Provisional pressure-outlet value; not a NASA pressure transcription. The Fluent outlet Mach is surface-mass-averaged; nominal NASA M2 is a differently defined pressure-derived operating-point quantity."
isentropic_update_estimate,236228.23601047668,,0.900000,1.4,local pressure-ratio correction,"Reconstructed from the retained project development log and formula documented in docs/outlet_pressure_selection.md","Calculated from p_old=241200 Pa and Fluent mass-weighted M_old=0.88064076 while using nominal NASA M2=0.90 numerically as the control target, assuming approximately unchanged total-pressure level over the local adjustment. This control calculation does not imply that NASA M2 and Fluent surface-mass-averaged Mach are definition-identical."
accepted_operating_point,236200,0.89951531,0.900000,1.4,applied rounded pressure-outlet setting,"Retained project development log, July 2026","Rounded from the 236228.236 Pa estimate and verified by the subsequent Fluent response. The 0.0539% normalized numerical mismatch to nominal NASA M2 is an operating-point consistency indicator between differently defined quantities, not a validation error or experimental uncertainty."
current_fine_sst,236200,0.901294441,0.900000,,released baseline boundary condition,"Committed fine-grid SST Fluent exports","Same selected pressure-outlet setting retained in the current fine-grid baseline. Fluent outlet Mach is a surface-mass-averaged local-Mach report; NASA M2 is pressure-derived. Their numerical proximity is an operating-point consistency check, not an independent or like-for-like validation metric."
