Golden validation

WinISD golden dataset and deviation browser

This public report tracks deterministic 00 Simulator fixtures against WinISD extraction artifacts. It is designed to show where the tools match, where they drift, and whether each release is moving the validation set in the right direction.

Fixture corpus

50 deterministic `.wpr` cases across sealed, vented, BP4, and BP6 alignments.

Comparison policy

9 graph metrics sampled at 18 shared frequencies with explicit tolerances.

Release signal

Machine-readable JSON and Markdown artifacts are committed for review and future CI.

Report notes & provenance

Fixture inputs and comparison policy are owned by 00 Simulator.
WinISD extraction output is treated as an external artifact owned by winisd-mcp.
Comparison points are graded excellent / pass / warn / fail per metric; excellent and pass both count as passing.
Transfer phase reports far-field pressure phase (the +90° monopole radiation lead is applied at the source, consistent with SPL magnitude), matching WinISD. Transfer phase and its group-delay derivative are graded only in-band — within 15 dB of the SPL peak — because out-of-band phase is pure wrap noise; out-of-band points are shown but marked not-applicable.
