We fuse idler hunting with hardware priors from
parametric amplifiers (ATL/TWPA): pump-locked 3WM/4WM
loci, stopbands, and RPM notch/pole sentinels. The result is a
unified, design-aware score that boosts precision under crowding
without model retraining. We define separate 3WM/4WM proximity terms with pump-referenced tolerances, apply stopband
penalties only to unexplainable energy, add RPM bonuses near
phase-matching sentinels, and auto-tune weights (w0, w3, w4) to
maximize PR-AUC. A press-once kit produces ROC/PR curves,
FPR@95%TPR, ablations over ppm and FIFO depth, and
a proximity heatmap. Real ops JSONL can be ingested to
reproduce results on field logs.
