Graham McIntire 7d68d13dcc Recalibrate scoring weights from gradient descent on 5000 QSOs ... Loss improved 72% (0.42 → 0.12). Key changes: - rain: 0.08 → 0.136 (+70%) — strongest discriminator - season: 0.08 → 0.111 (+39%) - wind: 0.05 → 0.08 (+60%) - refractivity: 0.08 → 0.105 (+31%) - time_of_day: 0.10 → 0.050 (-50%) — was overweighted by contest bias - pressure: 0.15 → 0.103 (-31%) - humidity: 0.18 → 0.124 (-31%) Validated by native profile backtest (11,431 profiles): theta_e_jump strongest native discriminator, duct_usable_* and bulk_richardson dropped as dead features.		2026-04-11 13:20:00 -05:00
