[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

# Session 23 turn 3 — 2026-05-15 — Plan M Fix F1 edge case + FE label rename
**Dev:** Claude Opus 4.7 1M (4 sub-agents active + em main coordinator)
**Duration:** ~2h
**Base commit:** `83c9f7b` (S23 t2 Plan L5 chốt)
**Final HEAD:** `4dd6f9c` (M2 tests) — local, CHƯA push remote (chờ Reviewer verdict)
**Total commits Plan M:** **3** (M1 + M3 + M2)
## 🎯 Trigger session
Bro UAT post-Plan L deploy (S23 t2 chốt ~02:00) phát hiện disconnect:
> "Hiện logic cũ là khi trả lại 1 cấp hoặc chỉ định hoặc edit là trạng thái draft -> cái này thay đổi lại nhé, các tính năng duyệt thẳng, trả lại 1 cấp hoặc người chỉ định hoặc cho edit thì cho xử lý đc ở trạng thái đang gửi duyệt luôn."
Em main pre-flight Investigator spawn audit code thực tế. **Verdict surprise:** code main path đã đúng (F1.OneLevel/Assignee + F2 + F3+F4 giữ ChoDuyet đúng spec Mig 28-31 cumulative). Chỉ **edge case F1.OneLevel/OneStep tại Bước 1** còn fallback Drafter (Phase=TraLai) — đây là "draft" bro phát hiện.
Bro 3 AskUserQuestion chốt spec Plan M:
- **F1.OneLevel/OneStep Bước 1**: reset (0, 1) giữ ChoDuyet (Recommended Option A — no-op effective + audit log)
- **FE Phase=TraLai display label**: rename "Trả lại" → "Cần chỉnh sửa lại"
- **F1.Drafter mode 4**: GIỮ NGUYÊN Phase=TraLai semantic (explicit role mode, KHÔNG phải fallback)
## 🌳 Plan M 3 chunk execution
### Chunk M1 — BE Service refactor F1 edge case (`c2042ef`)
👤 Chủ trì Solo (cross-stack reasoning F1 state machine — Implementer auto-refuse criteria #1 schema-ish + #4 bug-fix-reasoning).
File: [PurchaseEvaluationWorkflowService.cs:287-333](src/Backend/SolutionErp.Infrastructure/Services/PurchaseEvaluationWorkflowService.cs:287)
```diff
case WorkflowReturnMode.OneLevel:
// Lùi 1 Cấp trong cùng Step. Nếu đang Cấp 1 → lùi sang Bước trước
// Cấp cuối. Nếu đang Bước 1 Cấp 1 → reset về (0, 1) giữ ChoDuyet
- // → fallback Drafter (no further).
+ // (Plan M S23 t3 — KHÔNG fallback Drafter, phiếu giữ "đang duyệt").
if (curLevel > 1) { ... }
else if (curStepIdx > 0) { ... }
else
{
- // Bước 1 Cấp 1 — no further back. Fallback Drafter.
- evaluation.Phase = PurchaseEvaluationPhase.TraLai;
- evaluation.CurrentWorkflowStepIndex = null;
- evaluation.CurrentApprovalLevelOrder = null;
- evaluation.SlaDeadline = null;
- return "Trả về Người soạn thảo (fallback — đang Bước 1 Cấp 1)";
+ // Bước 1 Cấp 1 → reset về (0, 1) giữ Phase=ChoDuyet (no-op effective
+ // — Approver A hiện tại). Audit log rõ "không lùi được". SLA reset
+ // dưới cuối hàm cho approver giữ nguyên.
+ evaluation.CurrentWorkflowStepIndex = 0;
+ evaluation.CurrentApprovalLevelOrder = 1;
+ summary = "Action 'Trả lại 1 Cấp' không lùi được — phiếu reset về Approver Bước 1 Cấp 1";
}
```
OneStep analog: line 314-333 cùng pattern reset (0, 1) thay vì fallback Drafter.
**Verify:**
- `dotnet build src/Backend/SolutionErp.Infrastructure` clean (0 err, 2 warn pre-existing DocxRenderer)
- Diff 13+/13- LOC 1 file surgical
**KHÔNG đụng:**
- F1.Drafter line 268-275 (explicit role mode, giữ TraLai)
- F1.Assignee line 335-360 (giữ throw nếu không match)
- F2 ApproveV2Async line 483-524 (Plan L L1 fix unchanged)
- F3 EnsureEditableForDetailsAsync (Mig 28 wire unchanged)
- F4 AdjustBudgetCommand handler (Mig 30 wire unchanged)
### Chunk M3 — FE label Phase=TraLai rename × 2 app (`508b17a`)
🟨 Implementer Case 2 (cookie-cutter mirror 2 app, ~6K tokens spawn).
Files (4 FE + 1 MEMORY):
- [fe-admin/src/types/purchaseEvaluation.ts](fe-admin/src/types/purchaseEvaluation.ts): `PurchaseEvaluationPhaseLabel[98]` + `PeDisplayStatusLabel.TraLai`
- [fe-user/src/types/purchaseEvaluation.ts](fe-user/src/types/purchaseEvaluation.ts) mirror
- [fe-admin/src/components/pe/PeWorkflowPanel.tsx](fe-admin/src/components/pe/PeWorkflowPanel.tsx): F1 dialog tooltip + confirm message status reference
- [fe-user/src/components/pe/PeWorkflowPanel.tsx](fe-user/src/components/pe/PeWorkflowPanel.tsx) mirror
Diff +4/-4 LOC × 4 file = 8 LOC tổng. Mirror 2 app §3.9 strict.
**Scope decisions Implementer:**
- ✅ Rename 2 const map label (badge primary)
- ✅ Tactical extension: rename 2 inline literal "Trả lại" trong PeWorkflowPanel.tsx F1 dialog (tooltip + confirm message — status display reference, KHÔNG phải action verb). Anti-fiddle <20% LOC threshold respected.
- KHÔNG đụng `← Trả lại` action button, `Trả về Người soạn thảo` mode picker, comments narrative
- KHÔNG đụng `types/contracts.ts` + `types/budget.ts` Phase 98 (Contract + Budget module ngoài scope M3)
**Verify:** fe-admin npm build PASS clean (0 TS err, 9.40s) + fe-user PASS clean (0 TS err, 6.92s).
### Chunk M2 — Tests F1 edge case (`4dd6f9c`)
🟨 Implementer Case 3 (test generation cookie-cutter, ~14K tokens spawn).
File: [tests/SolutionErp.Infrastructure.Tests/Services/PurchaseEvaluationWorkflowServiceReturnModeTests.cs](tests/SolutionErp.Infrastructure.Tests/Services/PurchaseEvaluationWorkflowServiceReturnModeTests.cs)
2 test mới (Pattern 11 SeedWorkflowAsync helper extend 2 param optional `allowReturnOneLevelL1` + `allowReturnOneStepL2`):
- `ApplyReturnMode_OneLevel_AtStep1Level1_ResetsToBuoc1Cap1_KeepsChoDuyet`
- `ApplyReturnMode_OneStep_AtStep1_ResetsToBuoc1Cap1_KeepsChoDuyet`
Assertions:
- Phase.Should().Be(ChoDuyet) KHÔNG TraLai
- CurrentWorkflowStepIndex.Should().Be(0)
- CurrentApprovalLevelOrder.Should().Be(1)
- SlaDeadline.Should().NotBeNull (reset 7d)
- ContextNote contain "không lùi được" (KHÔNG `Summary` fix spec bug em main bị Implementer correct: `LogTransitionAsync` set Summary = "Chuyển phase {from} → {to}" cố định; summary từ `ApplyReturnModeAsync` chèn vào `comment` param ghi vào `ContextNote`)
**Verify:** `dotnet test SolutionErp.slnx` **106/106 PASS** (58 Domain + 48 Infra: +2 từ 46 baseline). K7 Approver F2 NO regression (3 `ApproveV2_SkipToFinal_*` tests still green M1 chỉ đụng F1 path).
Diff +94/-2 LOC test file + 22 LOC MEMORY append.
### Pending Chunk M4 + Reviewer verdict + push

## 🎯 Multi-agent ROI evidence Plan M
| Spawn | Agent | Cost (tokens) | Output | Catch |
|---|---|---|---|---|
| Pre-flight | 🟦 Investigator | ~20K | 7-feature audit matrix file:line + verdict "code main path đúng, chỉ edge case sai" | **Avoid em main spam refactor sai** verify 6/7 feature đã đúng spec, chỉ scope hẹp Bước 1 fallback cần fix |
| M1 | 👤 Chủ trì | ~self | 1 commit BE Service 13+/13- LOC | |
| M3 | 🟨 Implementer Case 2 | ~6K | 1 commit FE label rename × 4 file mirror | Tactical extension catch inline literal F1 dialog tooltip + confirm message |
| M2 | 🟨 Implementer Case 3 | ~14K | 1 commit tests 2 new + 106/106 PASS | Spec field bug catch (`ContextNote` vs `Summary`) + helper extend backward-compat |
| Reviewer | 🟥 Reviewer | ~22K (pending) | PASS verdict + Smart Friend guard | TBD post-spawn |
| Post-deploy | 🟩 CICD Monitor | ~150K (pending) | Bundle hash + smoke F1 endpoint | TBD post-push |
**Total Plan M spawn cost (excl Reviewer + CICD):** ~40K tokens well under 200K budget per session.
**Multi-agent value caught:**
1. **Investigator avoid em main spam refactor** bro statement "logic về draft" easy lead em main refactor toàn bộ 4 mode F1 + F2 + F3 + F4. Investigator catch fact code main path đã đúng scope giảm 80% (LOW effort vs HIGH).
2. **Implementer Case 3 catch spec bug `ContextNote` vs `Summary`** em main spec viết `Summary.Should().Contain(...)` sai field. Implementer correct test pass real, không pass-by-mistake.
3. **Implementer Case 2 tactical extension** rename inline literal trong F1 dialog tooltip + confirm message (cùng status reference disconnect). Anti-fiddle threshold respected, KHÔNG scope drift.
## ⚠️ Pending S23 t4+
- 🟥 **M-Review verdict** chờ Reviewer pre-commit Plan M cumulative
- 🟩 **CICD Monitor K-Plan-M** chờ push remote spawn post-deploy verify
- 🟡 **Plan B Contract V2 wire (Mig 32+33)** vẫn pending S23+ (HIGH priority next)
- **Plan F drop V1** defer sau Plan B + UAT 2-3 tuần
- 🟢 **Plan H PE PDF Export** LOW priority carry
- 🟡 **Plan I RAG Hybrid setup 5 dự án** defer chờ bro confirm
- 🔧 **Gotcha #47 paths-ignore agent-memory** PENDING bro confirm
## 📋 Pattern reinforced
- **Investigator pre-flight audit avoid em main spam refactor** khi bro statement vẻ "code sai" Investigator audit verify code đã đúng scope giảm drastically (LOW vs HIGH effort). Pattern reusable: BẮT BUỘC spawn Investigator pre-flight cho mọi bug fix scope > 50 LOC, KHÔNG em main solo audit (bias).
- **Edge case "không thực hiện được" KHÔNG fallback role khác** — pattern user-level reinforced trong `feedback_per_nv_permission_scope.md` S23 t3 entry. Action per-NV flag được trigger nhưng state machine không cho phép → giữ Phase hiện tại + reset pointer hợp lệ + audit log warning.
- **Service refactor semantic BẮT BUỘC test cùng commit** — Plan L L1→L4 lesson (CI #196/#197 FAIL cascade). Memory `feedback_uat_skip_verify.md` updated với rule mới.
- **Implementer Case 2+3 cookie-cutter 2 spawns parallel** — M2 (test) + M3 (FE) chạy background đồng thời ~6K + ~14K tokens. Em main solo M1 (cross-stack reasoning). Total Plan M token ~40K under 200K budget.
