First full recalibration since 2026-05-24. Corpus is 1,726,757 PSKR samples (50/144/432 MHz) plus 74,072 contacts joined to hrrr_profiles (microwave), yielding overrides for 12 bands. The 6m fit moved most, and coherently: humidity 0.125 -> 0.204 and pwat 0.120 -> 0.185, paid for by season 0.217 -> 0.147. 6m contributes 1.63M of the 1.73M PSKR samples, so ten weeks of new spot density pulled the band off a seasonal prior and onto direct moisture signal. Next largest is 144 MHz refractivity 0.111 -> 0.053. 75 GHz (n=93) and 122 GHz (n=63) appear in the evidence table but get no overrides -- they fall under MIN_N_FOR_FIT, which is correct; 75 GHz reports rho_pr of -0.774 on 93 samples, which is noise, not physics. Caveat: the refractivity multipliers are numerically unstable. They are computed as |band_rho_grad| / |ref_rho_grad| against the 10 GHz reference, whose rho_grad is +0.030 -- an order of magnitude smaller than the other reference correlations. Two runs minutes apart moved 47 GHz refractivity 0.0688 -> 0.0522 (-24% relative) purely on new rows landing between queries. The stable factors barely moved. These weights are live once deployed, so this commit is isolated from the script fixes to keep it independently revertable. |
