	saves on delay arms for dip-screening Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_014FAPDWQ49M5Ye3NpTndTpn
2026-07-04	magic-s2000 study: reg_delay/noadaptc flags, 4-arm queue v2, redx trajectory ↵	Yuren Hao
	audit - lt_ep_train: --reg_delay N (reg-free early phase: resreg/jr/floss/adaptc off for first N steps) + --noadaptc (kill hidden jacreg==0 damping feedback that would pollute single-reg ablation arms) - queue v2: 4 arms delay-first (abl_delay = reg-free 2k -> proven pair) - eig_traj/2/3: ARPACK audit of redx_traj — the run crossed the edge EARLY and oscillated (s1000 rotating-unstable, s1400 excursion mu=+2.1 self-recovered, s2000 the ONLY stable snapshot mu=-0.02, s2100/s2200 already back out) => s2000 is a post-excursion STABILITY-DIP capture, dip width <100 steps; learning survives mild instability (val fell through unstable stretches). lead_rho cold-40 under-reads clusters — NOT a classifier; ARPACK for audits.

2026-07-03	floss-ept: graded finite-horizon LE penalty (--floss) + three-arm ↵	Yuren Hao
	from-scratch ablation queue - ep_step: floss block after resreg — unroll q=10 steps past z_T1 on a sub-batch WITH graph, rho_hat = mean per-step delta growth, one-sided relu(rho_hat - 0.995)^2, ramp keyed on (rho_hat - target) NOT resT1 (de-cliffed resreg: same fundamental path-LE quantity, linear early signal), capped at floss fraction of task-grad norm (resreg convention). - smoke: below-target = untouched (cos 1.0000); force-fire = finite grads, capped perturbation (cos 0.9803). - runs/abl3_queue.sh (runner live): waits for free GPU slots (0/1/3, GPU2 excluded), launches abl_floss (floss-only) / abl_resreg (resreg-only, never cleanly run) / abl_pair (proven 2.09 recipe, control) with identical remaining flags + seed.
