[CLAUDE] Docs: Chunk M4 — S23 t3 Plan M wrap: docs + session log + 2 agent MEMORY drift

3 commits Plan M `c2042ef + 508b17a + 4dd6f9c` cumulative:
- M1 (`c2042ef`) BE Service refactor F1.OneLevel/OneStep edge case Bước 1 → reset (0, 1) giữ ChoDuyet (KHÔNG fallback Drafter)
- M3 (`508b17a`) FE × 2 app rename phase=TraLai display label "Trả lại" → "Cần chỉnh sửa lại"
- M2 (`4dd6f9c`) Tests add 2 edge case test 106/106 PASS (+2 từ 104)

Docs update:
- docs/STATUS.md — Last updated S23 t3 + stats 106 test (+2) · 20 memory (2 entry reinforced)
- docs/HANDOFF.md — TL;DR S23 t3 với multi-agent ROI evidence Investigator avoid em main spam refactor
- docs/changelog/sessions/2026-05-15-s23-turn3-plan-m-f1-edge-case.md — Session log đầy đủ

Memory user-level update (2 entry reinforced):
- feedback_per_nv_permission_scope.md — S23 t3 reinforcement "edge case không lùi được KHÔNG fallback role khác"
- feedback_uat_skip_verify.md — Plan L S23 t2 lesson "Service refactor semantic BẮT BUỘC test cùng commit"

Agent MEMORY drift (auto-flush per multi-agent rule §):
- Investigator (.claude/agent-memory/investigator/MEMORY.md) — S23 t2 spawn L2 entry + S23 t3 spawn M0 audit findings
- Reviewer (.claude/agent-memory/reviewer/MEMORY.md) — S23 t3 Plan M cumulative PASS-WITH-NOTES verdict + 2 Minor defer

Reviewer verdict: PASS-WITH-NOTES (26 checks PASS, 0 Major, 2 Minor defer).
- Minor #1: 5-8 inline literal "Trả lại" PE module FE còn (filter / hint / button verb mix) — verb button giữ, filter/hint defer
- Minor #2: Contract + Budget module Phase=98 vẫn 'Trả lại' — Plan M scope PE-only, defer

Stats Plan M chốt:
- 31 mig (no change) · 59 tables · ~145 endpoints · 34 FE pages
- **106 test PASS (+2: F1 OneLevel/OneStep edge case)**
- 47 gotcha · 20 memory (2 entry reinforced) · 6 skills
- 4 sub-agents (1 Investigator pre-flight + 2 Implementer Case 2+3 + 1 Reviewer pre-commit)
- 4 commits Plan M `c2042ef..HEAD` ready push

Pending: CICD Monitor post-deploy verify Plan M
