Composite 80/100 — passes blind match.
- 01Gate identified — PKN net pressure
Dispatcher routed entry "pkn-synthetic-baseline" to the pkn-netpressure forward evaluator.
- 02Reference inputs check
All required `referenceInputs` (and `extra` knobs, if any) resolved.
- 03Measured series check
1 series, 12 samples evaluated.
- 04Fit — BHP (synthetic)
RMSE within 10 % of series mean — tracks measured curve.
