+"""Ship-gate for holo_a_track_avg (trend-aware stop + plateau averaging, the semi-convergence fix):
+cos(EP,BPTT) at t2sel=160 on s2000 — the regime where argmin-t_best got fooled (t2_probe: batch2
+degraded 0.956->0.894 at 160). PASS = avg recovers the t2sel-80 level (~0.93+) at 160 without
+hurting the healthy batches."""
