[CLAUDE] Docs: Chunk G — K8 Plan K wrap S23 t1: docs + session log + Designer comment cleanup + 3 agent MEMORY drift

Plan K Mig 31 F2 refactor sang per-Approver-slot DONE — 8 commits cumulative
S23 t1 (`56868bf..<this>`). K8 wrap docs + dirty MEMORY.md commit:

Docs updates:
- docs/STATUS.md: Last updated S23 t1 entry với Plan K summary 8 chunk
- docs/HANDOFF.md: TL;DR S23 t1 đầy đủ (top) — multi-agent ROI evidence
- docs/database/schema-diagram.md §14: title Mig 22-31 (was 22-29) + add
  Mig 30 F4 + Mig 31 F2 blocks per slot Approver + DROP Users column note
- NEW docs/changelog/sessions/2026-05-14-s23-turn1-plan-k-mig31-f2-refactor.md
  session log đầy đủ 8 chunk timeline + multi-agent spawn cost table + pattern
  reinforced 3×

FE Admin Designer comment cleanup (Reviewer K2 follow-up):
- ApprovalWorkflowsV2Page.tsx lines 73-75 + 502-504: 2 stale narratives "F2
  AllowDrafterSkipToFinal xuống per User (User Management)" rewrite Mig 29+30+31
  cumulative narrative "7 Allow* ALL xuống per Level slot, pattern proven 3×"

3 agent MEMORY.md drift commit (dirty từ session start S23 + S22 chốt):
- Investigator: K0 pre-flight findings + 5 surprises catch
- Reviewer: K2 PASS report + new pattern "transient sentinel zombie" anti-pattern
- CICD Monitor: S22 chốt verify cumulative (Run #193 + S23 t1 pending K9 spawn)

User-level memory updates (cross-project diary persisted ngoài repo):
- feedback_per_nv_permission_scope.md: reinforcement S23 t1 — Pattern 3×
  cumulative (Mig 29 + Mig 30 + Mig 31). Pattern ALSO applies cho refactor existing
  scope, KHÔNG chỉ greenfield. Cross-ref discoveries Plan K (compile-break workaround,
  stale narrative drift, transient sentinel zombie anti-pattern caught Reviewer).
- MEMORY.md index: cumulative reinforcement note 3× Mig 31

Verify:
- dotnet build production projects clean
- npm run build fe-admin pass 17.76s, 0 TS err
- Test 104/104 PASS (S23 t1 K7 chunk maintained baseline)

Plan K state final: 31 mig · 59 tables · ~145 endpoints · 104 test · 47 gotcha
· 20 memory · 6 skills · 4 sub-agents active. CHƯA push remote — chờ bro confirm
K9 spawn CICD Monitor.
