The authored absolute band made pos>=1 unreachable for live hacks (rout~0),
and re-extracting it every 5 steps collapsed the gate (the #40 step-5 cliff).
- Online-stats gate: route by live quantiles of the pooled cos-to-v_grad
(top route_quantile -> hack, bottom -> keep, middle -> mid), window flushed
on refresh. v_grad stays authored-only; only the threshold follows the live
distribution. Smoke: routing sustained past the refresh (cliff fixed).
- Step-level teacher mix (#31): mix_ratio is a fraction of ALL the step's gens,
not a per-prompt round; symmetric hack+solve teachers injected as ordinary
gens (not specially routed). Fixes the per-prompt rounding wart.
- AUROC + cosU step columns: v_grad as a live hack-detector vs the hack-label
(measurement-only, never routes) -- discriminates threshold-vs-direction
failure and whether a refresh destroys separation.
- Inline eval stays off (eval_ablate_every=0); deploy scored offline.
- Fix _sample_rows None crash (beartype) on the no-solve-pool path.
- Remove dead pooled_gate_thresholds (the rejected authored-pooled approach).
