-- Paper A v3.20.0 shipped to partner Jimmy 2026-04-27, DOCX `~/Downloads/Paper_A_IEEE_Access_Draft_v3.20.0_20260505.docx`
+**Phase 1 (Foundation, 7 spike + foundation scripts)**:
-- Spike Scripts 32-35 (commits `e1d81e3` `8ac0988` `55f9f94`) confirming Big-4-only scope is methodologically superior:
+- Script 32 (`e1d81e3`): non-Firm-A calibration verdict C
-  - Script 32: non-Firm-A calibration verdict C (negative, but with the bifurcation twist)
+- Script 33 (`8ac0988`): reverse-anchor PAPER_C_STRONG (directional ρ=+0.744)
-  - Script 33: reverse-anchor PAPER_C_STRONG (rho=+0.744 directional / -0.927 bifurcation)
+- Script 34 (`55f9f94`): Big-4 K=2 dip-test multimodal p<0.0001, bootstrap CI [0.974, 0.977] / [3.48, 3.97]
-  - Script 34: Big-4-only K=2 with dip-test multimodal p<0.0001, bootstrap CI [0.974, 0.977] / [3.48, 3.97]
+- Script 35 (`55f9f94`): firm × cluster — Firm A 0% C1 / 82.5% C3, PwC 23.5% C1
-  - Script 35: firm × cluster cross-tab — Firm A 0% C1 / 82.5% C3, PwC 23.5% C1
+- Script 36 (`ccd9f23`): K=2 LOOO **UNSTABLE** (firm-mass conflation; max Δcos=0.028)
+- Script 37 (`92f1db8`): K=3 LOOO **PARTIAL** (component shape stable, membership ±5-13pp)
+- Script 38 (`bc36dcc`): convergence **STRONG** — 3 lenses pairwise ρ ≥ 0.879
+- Script 39 (`39575ce`): per-signature convergence **MODERATE** — κ=0.87 between per-CPA and per-sig K=3 fits
+- Script 40 (`338737d`): pixel-identity FAR = **0%** on n=262 ground-truth replicated
 
-## Pending — Phase 1 entry
+**Phase 2 (Methodology rewrite)**: §III-G..L draft delivered at `paper/v4/paper_a_methodology_v4_section_iii.md` (commit on the same branch). Single coherent rewrite covering 6 sub-sections (G/H/I/J/K/L); cross-references to all 9 spike scripts; 5 open questions flagged at end of draft for user decision.
 
-- [ ] Refactor scripts 19, 20, 21, 24, 25 to accept `--scope=big4|full` flag
+## Pending — Phase 2 user review (BEFORE Phase 3)
-- [ ] Define `reports/v4_big4/` output convention
+
-- [ ] Decide whether to retire Script 32-35 spikes or keep as historical artifacts (recommend: keep, treated as "v4.0 origin evidence")
+5 decisions needed from user before Phase 3 (Results regeneration) starts:
+
+1. §III-G scope justification — three-point argument enough, or add a fourth?
+2. §III-H Firm A phrasing — "case study of templated end" vs an alternative framing?
+3. §III-J K=3 vs K=2 selection — lean on LOOO (current draft) or strengthen BIC argument?
+4. §III-L hybrid classifier — keep inherited 5-way box rule, or commit to K=3 hard label as primary?
+5. Section IV table numbering scheme — confirm before Phase 3 builds tables.
+
+Plus: any prose-level edits the user wants on the §III draft.
