[CLAUDE] Docs: S22 chốt — Plan C+D+E done, Plan F ABORTED + 3 agent MEMORY drift patch

Session 22 final docs:
- STATUS Last updated S22 + S21 chốt cuối preserved row (§6.5 KEEP narrative)
- HANDOFF Last updated S22 + S21 row preserved
- Session log mới `2026-05-13-1800-s22-plan-cde-test-strict-v2.md` (260 LOC)
  + narrative 4 plan + pre-flight evidence + lessons learned

Cross-agent sync (start-of-session): 3 agent MEMORY.md drift patch
(KHÔNG cắt narrative — chỉ count update):
- investigator/MEMORY.md: 27→29 mig + 81→84 test + 44→46 gotcha + 16→19 memory
  + Mig 28/29 narrative ngắn + Gitea API discovery cross-ref
- implementer/MEMORY.md: test baseline 81→84
- reviewer/MEMORY.md: 81→84 test + 44→46 gotcha + Mig 29 per-NV scope line

CICD Monitor MEMORY.md đã fresh từ S21 t5 — KHÔNG đụng.

Plan F ABORTED reason:
- Contract entity HOÀN TOÀN V1 (no ApprovalWorkflowId column)
- Prod 23 PE + 4 V1-only PE + 7 Contract pin V1
- Drop V1 BE crash startup → defer sau Plan B Contract V2 wire

 **S21 turn 5:** 2026-05-13 1400 (Session 21 turn 5 — **🎯 Refactor Allow* sang PER-NV (Mig 29). 4 chunk per-commit `0366946` (A BE+Mig 29) → `63234b2` (B FE Admin Designer per-Level 5 checkbox) → `5ccb2a7` (C FE eOffice mirror 2 app rename) → this Chunk D Docs. **F1+F3** 5 flag MOVED xuống `ApprovalWorkflowLevels` (per slot Approver). **F2** MOVED xuống `Users` (per-Drafter). Mig 29 4-stage: ADD 5 Levels + 1 Users + BACKFILL bulk SQL preserve admin config S21 t4 + DROP 6 workflow column. Service refactor đọc `currentLevel.Allow*` + `drafterUser.AllowDrafterSkipToFinal`. DTO `AwLevelDto +5`, `PeDetailBundle.workflowOptions → currentLevelOptions + drafterAllowSkipToFinal`. FE Admin Designer 5 checkbox per Level slot inline (drop section workflow-level). 84 test PASS. CHƯA push remote — chờ bro confirm.**)
 **S21 turn 4:** 2026-05-13 1200 (Session 21 turn 4 — **🎯 F1+F2+F3 PE Workflow advanced options (Mig 28) — 5 chunk per-commit `0294693` (A schema) → `c56024b` (B BE) → `a508564` (C FE Admin) → `d27caaf` (D FE eOffice) → this (E Docs). **F1** 4 mode Trả lại admin tick stick (1 Cấp / 1 Bước / Người chỉ định / Người soạn thảo) — 3 mode đầu giữ Phase=ChoDuyet lùi pointer (peer review chain), mode Drafter giữ Phase=TraLai clear pointer (S17 backward compat). **F2** Drafter skip thẳng Cấp cuối — workflow tick + Workspace checkbox dynamic. **F3** Approver edit Section 2 (Hạng mục/NCC/Báo giá) khi workflow tick + actor match CurrentLevel.ApproverUserId + audit ghi PurchaseEvaluationChangelog. Mig 28 thêm 6 bit column lên `ApprovalWorkflows` (DEFAULT 1 cho AllowReturnToDrafter backward compat, 5 còn lại 0). BE Service extend signature 3 optional param (returnMode/returnTargetUserId/skipToFinal). Helper `EnsureEditableForDetailsAsync` mới gating Detail/Quote/Supplier CRUD theo Drafter scope OR F3 Approver scope + audit changelog Update/Delete (trước đây silent).

 **S21 turn 3:** 2026-05-12 2100 (Session 21 turn 3 — **🔴 BUG FIX CRITICAL "Trả về nhưng hệ thống vẫn duyệt" PE workflow (gotcha #45 mới). 3 chunk per-commit: `de00887` (BE Chunk A guard + 3 test) + `4b29d00` (FE Chunk B fix 2 app mirror) + this Chunk C Docs. Root: `PeWorkflowPanel.tsx` `isReject` payload (L64-66) thiếu nhánh TraLai → button "← Trả lại" gửi `decision: 1` (Approve) thay vì `2` (Reject) khi target=TraLai(98) → BE skip Reject branch → enter APPROVE STEP → `ApproveV2Async` UPSERT opinion "đã duyệt" + advance Cấp tiếp theo. Inconsistency phụ: dialog `isSendBack` (L247-248) cùng pattern thiếu TraLai → dialog title sai `'✓ Duyệt → Trả lại'` + KHÔNG amber warning. Severity CRITICAL — data integrity issue khó rollback (BE đã `SaveChangesAsync`). Test-before §7 BẮT BUỘC: viết test reproduce → confirm FAIL (BE đi sâu vào ApproveV2Async throw "Phiếu chưa pin workflow") → thêm BE guard early throw ConflictException khi `target ∈ {TraLai, TuChoi} && decision != Reject` → confirm PASS. 3 regression test (Throws TraLai+Approve, Throws TuChoi+Approve consistency, happy path Reject+TraLai). Tổng `dotnet test SolutionErp.slnx` 84 PASS (58 Domain + 26 Infra = +3 from 81 baseline). `npm run build` × 2 app pass. Stats: 27 mig (no change) · 59 tables · ~142 endpoints · 34 FE pages · **84 test (+3)** · **45 gotcha (+1 #45)** · 17 memory · 6 skills · 4 sub-agents seeds-only.
