Synthetic and live scores share an axis with meaningful zero (raw scores carry a
common <mu,v> offset since v = mean diff is not orthogonal to the family mean).
Zones come from label-free online stats (EMA mean/std + Otsu valley), replacing
mean+k*sd which placed both cuts beyond every distribution. Winsorize at 1/99%
before Otsu: variance-maximizing cuts otherwise buy a class for one outlier.
Fresh-eyes review verified z-norm is affine (AUROCs unchanged), zones label-free,
P/R recompute from parquet matches titles.

Gate calibration: route by live mean + route_std_mid/route_std_rout * std of the
pooled cosine-to-v_grad, not a fixed quantile tail. Self-silences -- only the tail
that genuinely exceeds the spread routes, so qmass tracks real separation instead
of a forced fraction. The authored absolute band is mis-placed (live pos sits far
below the synthetic-hack edge; even synthetic solve out-aligns on-policy hack).
tablelog: auroc/rout/routE/keep/resid/qmass cols always shown (nan on vanilla) so
arm tables line up.
Diagnostics: scripts/diag_pinning.py (4-population calibration view, mean+/-2sd band)
and scripts/diag_pinning_refresh.py (proves cosine stats recompute from a tracked
v-independent gradient cloud on a v_grad refresh -- exact for k=1, sanity 2.5e-16).
