2026-04-08paper v2.31.9: relabel "StudentNet" → "no-terminal-LN ResMLP"YurenHao0426
The §3 ¶3 / §5 ¶3 / Figure 5 / §7 mentions of "StudentNet" as a cross-architecture validation case were a misleading rebrand of the no-terminal-LN ResMLP-d256 ablation. Verified by tracing the data: results/protocol_audit/temporal_evolution_s{42,123,456}.json final_acc 0.332/0.313/0.336 (matches no-outln 3-seed 0.327±0.012) first_fire_a {18, 14, 25} first_fire_b None / None / None The actual synth StudentNet (results/snapshot_synth_v1, d=128 alpha=1.0) has max-per-block growth ~6.88 over 80 epochs and never reaches the 50× threshold, so diagnostic (a) does NOT fire on the real synth StudentNet at all. Calling the no-outln data "StudentNet" doubled- counted the same architecture under two names (the same-backbone causal control AND the cross-arch generalization test). Relabeled to "no-terminal-LN ResMLP" everywhere it appeared: - §3 ¶3 paragraph 1 cross-arch list - §3 ¶3 paragraph 2 (now with explicit per-seed first-fire epochs {18,14,25}) - §5 paragraph (the conclusion) - §7 conclusion (cross-arch list) - Figure 5 caption - Figure 5 row label (with re-rendered PDF) The remaining cross-arch generalization claim is now: ViT-Mini fires both diagnostics, ResMLP at d=256/d=512 fires both, no-terminal-LN ResMLP and BatchNorm CNN fire only (a) — three real architecture classes, with the no-LN ablation being the same-backbone control rather than a separate architecture. The cross-arch story is slightly weaker ("3 architecture classes" not "4") but truthful and self-consistent. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
2026-04-08Figures 3 and 4: fix aspect ratio (fig3 was squeezed strip) and key-finding ↵YurenHao0426
label overlap (fig4) Per user feedback: - fig4_penalty_rescue.pdf (Figure 3 in paper): was figsize=(13, 3.5), aspect 3.7:1, which rendered as a thin strip with squeezed subplot content. Increased height to figsize=(13, 6.0), aspect 2.2:1. Much taller panels that actually show axis labels and legends readably. - fig5_cross_arch_summary.pdf (Figure 4 in paper): the 'Key finding' italic text annotation at y=-1.0 in axes transform was overlapping with the multiline architecture y-tick labels at the bottom of the second subplot. Moved to y=-1.55 and increased figsize height from 3.5 to 4.2 so the lower annotation still fits in bbox_inches='tight' crop. - Also bumped includegraphics width from 0.92\linewidth to \linewidth for both figures so they use the full text width. Main content still exactly 9 pages within E&D budget. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
2026-04-08Fill in tables 1-3 + generate figures 2/4/5 from existing dataYurenHao0426
Tables filled with real values: Table 1: 5-method audit (3-seed mean ± std for acc, headline Γ, verdict) Table 2: 4-condition mode 2 validation (cos and ρ values from existing checkpoint measurements) Table 3: protocol thresholds (50×, 1e-7, 0.30, 2pp) Figures generated from existing data: fig2_decision_utility.pdf: 5×7 verdict heatmap from results/protocol_audit/ablation_decision_utility.json fig4_penalty_rescue.pdf: 3-panel — trajectory + cos/ρ bars + 2×2 acc from snapshot_evolution_v2 + dfa_residual_penalty + bp_with_penalty fig5_cross_arch_summary.pdf: 5×4 BP/DFA verdict matrix across architectures Compiles to 8 pages with all tables/figures rendered. §1-§7 main body still has only paragraph topic sentences (TODO: per-section prose filling via codex). Figure numbering is wrong (codex put figures in section order not numerical order — need fixing).
2026-04-08v2 skeleton from round 25: section structure now matches round 23YurenHao0426
Round 24's skeleton had 3 deviations from round 23 redo: - Made §3 'Diagnostic Protocol' instead of 'Failure Mode 1' - Collapsed Mode 1 + Mode 2 into one §4 - Added §6 'Reference Implementation' (was supposed to be dropped) Round 25 fixed all three. New §3-§7 match round 23 redo exactly: §3 Failure Mode 1: Measurement Degeneracy §4 Failure Mode 2: Low Intrinsic Credit-Direction Quality §5 Intervention and Cross-Architecture Evidence §6 Recommended FA Evaluation Protocol §7 Discussion, Limits, Conclusion Also added: - In-line bibliography with 12 \bibitem entries (Paleka, O'Bray, Jordan + FA literature) — citations resolve correctly now - Appendices A-G with actual prose content (not just headers) - 7-pitfall catalog with descriptions - Walk-back chain methodology paragraph - 7-validation summary table Compiles to 9 pages with figures 1+3 inline (existing PNGs) and figures 2/4/5 as placeholder text PDFs (TODO: regenerate). Tables 1/2/3 still have TODO placeholders for numerical values. Next: fill in tables 1-3 with existing JSON data, generate figures 2/4/5 from existing data, then consult codex per-section for prose filling.
