[CLAUDE] Scripts Docs: Chunk R — Cleanup destructive prod database (52 rows + ~600 cascade child)

Bro UAT confirm Plan P+Q wire OK + chỉ thị cleanup test data:
> "OK Tao thấy tạm ổn rồi đấy, mày xóa hết các phiếu test cũ đi nhé,
> các quy trình cũ ko ghim cũng xóa hết đi. Cho gọn đẹp."

Investigator pre-flight audit prod DB ~64K spawn confirm scope:
- 35 PE rows total (28 active + 7 soft-deleted)
- 17 ApprovalWorkflowsV2 (15 IsUserSelectable=false + 2 ghim+active)
- 4 PurchaseEvaluationWorkflowDefinitions V1 (2 IsActive=false + 2 active)

Critical gotchas:
1. PE.ApprovalWorkflowId FK Restrict → soft-delete KHÔNG release FK,
   hard-DELETE PE first
2. ApprovalWorkflow extend BaseEntity (NO soft-delete) → hard DELETE only
3. Filtered indexes Mig 29+ require SET QUOTED_IDENTIFIER ON
4. SQL Express constraints: NO BACKUP COMPRESSION + RESTORE VERIFYONLY
   require sysadmin (vrapp KHÔNG có)

Execute via scripts/plan-r-*.sql upload scp + sqlcmd -i workflow:

Step 1+2 — BACKUP DATABASE:
- C:\Backup\SolutionErp_pre_cleanup_2026-05-15.bak (18.5MB, 2249 pages)
- Verified via Get-Item file size

Step 3-5 — 3 separate transactions DELETE:
- 28 PE active + 7 soft-deleted → cascade 446 child rows
  (42 Details + 49 Suppliers + 64 Approvals + 238 Changelogs +
   10 Attachments + 43 LevelOpinions)
- 15 V2 workflows unghim → cascade ~140 Steps+Levels
- 2 V1 workflows inactive → cascade ~37 Steps+Approvers

Total: 52 rows direct + ~600 cascade child = ~650+ rows wiped.

Step 6 — Verify post-cleanup state:
- PE total: 35 → 0 ✓
- V2 workflows: 17 → 2 (QT-DN-V2-001 v16 + QT-DN-PA-V2-001 v2 ghim+active)
- V1 workflows: 4 → 2 (QT-DN-A v3 + QT-DN-B v1 active, PE pin protected)

Step 7 — BE smoke verify alive post-cleanup:
- /api/auth/login → 200
- /api/purchase-evaluations → 200
- /api/approval-workflows-v2 → 200
- /api/pe-workflows → 200
→ KHÔNG crash startup (Plan F precedent avoid được)

Multi-agent ROI: Investigator save em main hard-delete blind without
backup + catch SQL Express constraint + catch FK Restrict gotcha.

Pattern reinforced:
- Destructive operation prod BẮT BUỘC pre-flight audit + backup + verify
- scp + sqlcmd -i workflow cho complex SQL trên prod (avoid shell escape
  hell qua SSH PowerShell)
- Plan F precedent: KHÔNG drop active workflow (PE pin → BE crash)

Stats final S23 t8:
- 31 mig · 59 tables · ~145 endpoints · 34 FE pages · 111 test unchanged
- 47 gotcha · 20 memory · 6 skills · 4 sub-agents
- **0 PE phiếu test + 4 workflow ghim/active** — UAT clean slate
- Backup rollback ready: vietreport-vps:C:\Backup\SolutionErp_pre_cleanup_2026-05-15.bak

 **Last updated S23 t5:** 2026-05-15 (Session 23 turn 5 — **🎯 Plan O HOTFIX: 4 lookup sites cùng pattern per-NV cascade — Plan N chỉ catch 1/5 sites**. Bro UAT sau Plan N: Actor NV Test trong OR-of-N click "Trả lại Người chỉ định" → "Không phải lượt bạn" mặc dù đúng slot. Em main grep audit phát hiện 5 lookup sites cùng bug, Plan N chỉ catch 1. Plan O fix 4 sites còn lại: Service.cs:201 (EnsureCanRejectV2Async = bug bro), Service.cs:248 (ApplyReturnModeAsync read Allow flag), DetailFeatures.cs:72 (F3 guard), Features.cs:311 (F4 AdjustBudget guard). ApplyReturnModeAsync signature +`Guid? actorUserId` 4th param + caller TransitionAsync:94 update. 3 regression test mới `PurchaseEvaluationPerNvLookupRegressionTests`. **111/111 PASS** (+3 từ 108).
