2026-07-06bp_lm twin control + env forensics probes + holo_a_track_avg ↵Yuren Hao
(semi-convergence fix, ungated) BP+EMA 2x2 (local, healthy env): qknorm {1.9951, 1.9977}, no-qknorm {1.9728, 1.9732} -> parameterization-matched BP twin tops at ~1.97 vs EP 1.7888: the equilibrium computation's iteration/depth dividend = 0.18 CE from identical parameters. External anchor (tuned depth-1 BP, 1.7921): EP at parity. bp_lm on 107/2.3.1 gave 1.9823 ~= local -> plain backward exonerated on the pascal env; the 107 divergence (pair/floss/resreg dead by step 600) narrows to the EP reg/estimator loop. Single-step fingerprints all match (a/b/c/d) -> suspected intermittent kernel issue; discriminators in flight (torch-2.7 env probe + delay_hr2's step-2000 reg-on transition).
