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.

eigreg v2 = true map-eigenvalue (spec_penalty)
- eig_control: fix plain-PI bug (shifted PI for lambda_max of indefinite Sym);
add lead_rho + spec_penalty (soft one-sided cap on |lam|(I+eps*J_F), 2-D
Rayleigh-Ritz, matvec-only) — aep 'spectral' ported. eig_penalty demoted to
diagnostic.
- eig_recheck.py (Lanczos audit): omega=+5..+13 on ALL operators incl the
stablest (s2000 +12.8 while true alpha=-0.02); gap omega-alpha~10; old
'warm -10.14 vs scratch +1.11' numbers were PI-mixture artifacts. RETRACTED.
- eig_v2_smoke/depth: v2 mechanics validated vs ARPACK; z_T1 readings >1 are
unconverged-state contamination (150: 1.009 -> 400/800: 0.997-0.999,
mu=-0.02..-0.006 matching eig_probe); fixed-point top = BAND of slow modes.
- lt_ep_train: --eigreg now spec_penalty (--eig_margin 0.995 = rho target);
--fingerprint reports rho/Re_mu instead of num_abscissa.
- ONBOARDING §4-7 + FINDINGS 2026-07-03: retraction + verdict (fundamental
quantity = finite-horizon path LE / resreg axis; de-cliff via floss-ept;
spec_penalty = measure-mode scalpel for a detaching Hopf pair).

Code (ep_run/), organized docs (docs/{method,campaign,hardware,outreach,paper}),
analysis scripts (scripts/), ONBOARDING.md entry point. Large data/checkpoints
git-ignored (share separately).
