[CLAUDE] Docs: Chunk N4 — S23 t4 Plan N HOTFIX wrap: docs + session log + 2 agent MEMORY drift

Plan N 2 commits:
- N1+N2 atomic (commit 0326458) BE fix line 765 ApproverUserId discriminator + 2 regression test
- N4 (this) docs + memory update

Docs update:
- docs/STATUS.md — Last updated S23 t4 + stats 108 test (+2 từ 106)
- docs/HANDOFF.md — TL;DR S23 t4 với Investigator pre-flight catch root cause
- docs/changelog/sessions/2026-05-15-s23-turn4-plan-n-per-nv-lookup-bug.md — Session log Plan N

Memory user-level update (1 entry CRITICAL HOTFIX section):
- feedback_per_nv_permission_scope.md — Wire checklist 9 surface points (NOT 8)
  + Point 9 mới: Handler lookup site `currentLevelOptions` MUST discriminate
  ApproverUserId. 3× cumulative gap analysis Mig 29 + 30 + 31.

Agent MEMORY drift (auto-flush):
- Investigator (.claude/agent-memory/investigator/MEMORY.md) — S23 t4 spawn N0
  audit Hypothesis B verdict + sqlcmd verify + API curl verify
- CICD Monitor (.claude/agent-memory/cicd-monitor/MEMORY.md) — S23 t3 Plan M
  Run #200 anomaly note (docs-only trigger CI mặc dù paths-ignore)

Stats final S23 t4:
- 31 mig · 59 tables · ~145 endpoints · 34 FE pages
- **108 test PASS (+2: per-NV lookup discrimination regression)**
- 47 gotcha · 20 memory (1 entry reinforced CRITICAL section)
- 6 skills · 4 sub-agents (1 Investigator spawn ~80K)
- 2 commits Plan N `0326458..HEAD` ready push

Pending: CICD Monitor post-deploy verify Plan N
