dip-map-calibrated
Dip screening (4/4 seeds have dips; first-dip cluster 1200-1700, width
100-300 steps, depth |lam|~0.998 = s2000-class; s2 shows excursion->dip in
sequence): reg-free until a scout (warm lead_rho, every gov_k=100, deep-400
subbatch) flags rho<0.985 after gov_min=1000, then ARPACK-certify all top-3
|lam|<1 -> leash ON (pair regs). Post-engagement: sustained rho_scout>1.02
x2 -> rescue boost (resreg x3 for 500 steps; the proven hr2 maneuver).
abl_delay's fixed-2000 death explained: it engaged AFTER the dip cluster,
mid-excursion. Two governor seeds launched on 107 (trained-state engagement
is Pascal-safe per hr2 precedent).

near-edge (eval-only); dp_ep.py ready
Anderson: res 25-35x deeper per budget but 5.8x slower (naive history stacks
+ per-iter safeguard eval) — v2 = ring buffers + periodic safeguard, est +1.3x
on the speed tier. bf16+20polish: 1.41x free phase, res parity, BUT z-diff
1.2e-3 — near-marginal operators contract too slowly for a 20-step polish
(0.998^20≈0.96), same magnitude as the TF32 kill verdict and the estimator's
50%-sensitivity input. Predicted by our own depth/noise theory. Flags kept
with warnings; neither ships for training. dp_ep.py: manual-allreduce EP DP
(controller in lockstep, aligned collectives), smoke pending freed 1080s.

(0.91x, cos 0.94, avg free); compile demoted
Full-ep_step wall times on quiet A6000 (warm s2000, B24), res parity across
all 8 configs. compile only 1.12x at this shape (historical 1.46x was a
different workload split); FULL cmp_sdpa saves 4% over eager at t80 — not
worth the guard complexity. tforce_sdpa added (flash baked into compiled
graph, flag-free so grad paths never see SDPA). bp_lm --tie probe in flight.

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.

phase, z* parity 4e-7
Scoped via blk._sdpa set only inside relax()'s loop (grad paths jvp/vjp/resreg
keep the manual attention: no forward-mode-through-flash risk). Combined with
--holofast: ~1.51x full-step exact-math tier.

passed
holo_a_track computed the doubled-batch jvp/vjp on [v0; -v0] at a shared
anchor zbar — exact antisymmetric redundancy (phase deviations from the
common mode are exact negatives). holo_a_track_fast computes at batch B and
mirrors: single-eval parity 6e-7 (exact); trajectory-level 45% divergence
SHARED with the original's own FD noise floor (1e-6 state noise -> 49%
self-divergence — the 2r=0.04 finite difference amplifies fp noise; training
averages it via pema/momentum). Ship gate: cos(EP,BPTT) orig vs fast
indistinguishable (0.907/0.912, 0.853/0.853, 0.918/0.918). Timing 6.43->4.16s
on the T2=40 nudged phase (contended GPU, relative). --holofast flag,
default off; queued ablation arms deliberately stay on orig for fidelity.

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.

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).
