tooling
trend-aware stop + plateau averaging recovers the semi-convergence victims
exactly as predicted. Estimator pack now: holofast+sdpa+t2sel80(+holoavg).
Also: bp_lm stdinit/beta2/sched flags (anchor archaeology), dipfarm_freezer,
staged tol_sweep.sh (gated on hr2 verdict), bp_sweep.sh.

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.

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.
