2026-07-12RESULT 13: bsign neutral at 4k (1.7382 vs 1.7314); 42M gap-chasing closed at ↵Yuren Hao
noise floor; pivot to Stage-2 pipeline + E-tier
2026-07-11RESULT 12: f3e3cont negative (1.2883 vs 1.2808) — residual gap not ↵Yuren Hao
beta-liftable; next lever = random-sign beta (single-phase, KHS-validated), then centered
2026-07-11STANDING: looped line abandoned (user directive) — cascade-only default; ↵Yuren Hao
looped = historical data for dynamics paper
2026-07-11RESULT 11: stage1b sealed (gap 0.050); beta ceiling unfound (3e-3 -> cos ↵Yuren Hao
0.9974); K exonerated on OLMo2; bf16 naive-cast dead at any beta (TF32 stays cost baseline); f3e3 CE-endpoint cont launched Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_014FAPDWQ49M5Ye3NpTndTpn
2026-07-10Queue: double-sided nudge after stage1b (0.22 = differential-measurement SNR ↵Yuren Hao
tax, escalation ladder recorded)
2026-07-10RESULT 10: epoch endpoints (BP 1.2509/1.2750 vs EP 1.4802, +0.22 erosion ↵Yuren Hao
cost); GENERATION GATE PASSED (casc_gen.py, coherent stories, no-backprop 42.75M); stage1b improved-recipe pair launched (Muon cosine via build_hybrid) Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_014FAPDWQ49M5Ye3NpTndTpn
2026-07-10cos<0.96: flagship stays as control; bf1e3 continuation from s40000 queued ↵Yuren Hao
on farm -> endpoint quad EP-ctl/EP-lift/BPx2
2026-07-10Sustained dose-response sealed (3e-4/5e-4/1e-3 -> 0.975/0.983/0.990); ship ↵Yuren Hao
--bf_late floor ramp; next-run recipe locked (OLMo2+Muon+late-ramp)
2026-07-10RESULT 8 sealed (Muon 3v3: BP 1.7098 / EP 1.7314); beta-floor dose-response ↵Yuren Hao
@25k: 3e-4/5e-4/1e-3 -> cos 0.984/0.989/0.994, stable at 1e-3; Stage-2 recipe = late floor ramp
2026-07-10Watch: late-epoch cos erosion = intrinsic late-training SNR decline; let it ↵Yuren Hao
run, BP twins are the measurement; floor-probe queued
2026-07-10RESULT 8 final: Muon generic (+0.13 both columns; BP+Muon 1.7020 vs EP+Muon ↵Yuren Hao
1.7254); Muon default from Stage-2; 3v3 fill launched
2026-07-10RESULT 9: wall-2 ELIMINATED by OLMo2 arch — epoch cleared 10-14k with zero ↵Yuren Hao
guard events (old arch: blowup@12100); cos-erosion watch armed
2026-07-10RESULT 8 prelim: Muon+beta_floor on EP = 1.7316 (-0.098 vs AdamW, n=1, zero ↵Yuren Hao
skips); retraction closed; BP+Muon control + s2 launched
2026-07-10RESULT 7: OLMo2 parity PASS (BP 1.8335 vs EP 1.8643, gap +0.031 within ↵Yuren Hao
metric noise); arch worth ~0.08 CE both columns; epoch auto-launched; Pascal unbanned (canaries green), farm running 2xBP epochs + Muon retest
2026-07-10RESULT 6 addendum: K8 also blew at 12600 -> wall-2 is true contractivity ↵Yuren Hao
crossing (K delays only); kretry demoted to mitigation; defense = OLMo2 arch > lr channel > damped-fb/jacreg
2026-07-10RESULT 6: wall-2 = EP-specific marginal under-convergence at the ↵Yuren Hao
contractivity edge (A skips16/B skips2/C skips1/D-BP clean); ship --kretry (retry marginal batches at K=kmax); launch OLMo2 parity matrix with parity-gated epoch autolaunch Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_014FAPDWQ49M5Ye3NpTndTpn
2026-07-10AUDIT: retract confounded Muon verdict; tone down parity claims (n=3, ↵Yuren Hao
best-of-noisy-val); scope depth-tax claim to 4k horizon; guard-split skip telemetry (skd/skg); add BP control arm diag_D_bp (+--resume in BP trainer); record resume confounds Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_014FAPDWQ49M5Ye3NpTndTpn
2026-07-10Stage-1 epoch blowup @12100: sig story REFUTED (only +8%, cos fine till ↵Yuren Hao
after); leading indicator=drift-guard skips -> contractivity bifurcation in nudged relaxation (cascade Hopf wall); add resume/sig0/final_ln; A/B/C diagnostic launched
2026-07-10RESULT 4: QK-norm validated parity-preserving (EP 1.8868 <= BP 1.9066); ↵Yuren Hao
qk_norm complements but does NOT replace beta-floor (sig_tok still grows); Stage 1 TinyStories epoch launched
2026-07-10QK-norm: replace nn.MHA with explicit SDPA attn + --qk_norm (OLMo2-style, ↵Yuren Hao
analog-friendly); cancel epoch, insert 8-run qk validation, stage roadmap TinyStories-epoch->FineWeb-Edu->OLMo2
2026-07-10RESULT 3: K4 depth-parity SEALED EP-favorable (EP 1.8907 <= BP 1.9192 @ ↵Yuren Hao
L12xC512); full-epoch generation run auto-launched (6.9h)
