[CLAUDE] Tests: Chunk M2 — Add F1 OneLevel/OneStep edge case tests Bước 1 reset ChoDuyet

Hai test mới cover edge case Plan M S23 t3 (em main M1 edit
PurchaseEvaluationWorkflowService.cs line 287-333):

- ApplyReturnMode_OneLevel_AtStep1Level1_ResetsToBuoc1Cap1_KeepsChoDuyet
  PE init Step 0 Cấp 1 + actor=a1 + slot Cấp 1 tick AllowReturnOneLevel.
  Trước fallback Drafter Phase=TraLai → sau reset (0, 1) giữ Phase=ChoDuyet,
  SLA reset 7d, audit log ContextNote chứa "không lùi được".

- ApplyReturnMode_OneStep_AtStep1_ResetsToBuoc1Cap1_KeepsChoDuyet
  PE init Step 0 Cấp 2 + actor=a2 + slot Cấp 2 tick AllowReturnOneStep.
  Service check curStepIdx > 0 → fallback ngay. Assert Phase=ChoDuyet,
  pointer (0, 1), SLA reset, audit log "không lùi được".

Extend helper SeedWorkflowAsync +2 params optional (allowReturnOneLevelL1
+ allowReturnOneStepL2) — default false, không phá compat 4 test ReturnMode
existing. Pattern 3 audit-reuse (extend helper KHÔNG clone).

Audit log assertion dùng ContextNote thay vì Summary: LogTransitionAsync set
Summary cố định "Chuyển phase {from} → {to}", summary từ ApplyReturnModeAsync
chèn vào comment qua line 96-99 service → ContextNote = comment.

K7 cascade NO regression: 3 ApproveV2_SkipToFinal_* tests still green (M1
edit chỉ F1 path, KHÔNG đụng F2 ApproveV2Async).

Verify:
- Build pass (0 error, 2 pre-existing DocxRenderer warning)
- 106/106 test pass (58 Domain + 48 Infra: +2 từ 46 baseline Plan L)
- 10 ReturnMode-class tests pass (4 ReturnMode + 3 ApproveV2_SkipToFinal
  + 1 Reject_NonApprover + 2 edge case mới)

+- **2026-05-15 (S24, Plan M Chunk M2 PASS):** F1 edge case Bước 1 reset ChoDuyet tests (em main M1 service edit `PurchaseEvaluationWorkflowService.cs` line 287-333 đã DONE — fallback Drafter TraLai → reset (0, 1) giữ ChoDuyet + audit log "không lùi được"). Cookie-cutter 1 file test `PurchaseEvaluationWorkflowServiceReturnModeTests.cs` — 2 sub-tasks: (1) extend `SeedWorkflowAsync` helper +2 params optional `allowReturnOneLevelL1` + `allowReturnOneStepL2` (default false, không phá compat 4 test ReturnMode existing), set vào `l1.AllowReturnOneLevel` + `l2.AllowReturnOneStep` tương ứng — Pattern 3 audit-reuse EXTEND không clone helper; (2) add 2 `[Fact]` test ngay sau test admin bypass OneLevel (line 241) — `ApplyReturnMode_OneLevel_AtStep1Level1_ResetsToBuoc1Cap1_KeepsChoDuyet` (PE init Step 0 Cấp 1 + actor=a1 + slot Cấp 1 tick AllowReturnOneLevel, build PE inline vì helper `BuildPeAtLevel2` không phù hợp cho Cấp 1) + `ApplyReturnMode_OneStep_AtStep1_ResetsToBuoc1Cap1_KeepsChoDuyet` (PE Step 0 Cấp 2 + actor=a2 + slot Cấp 2 tick AllowReturnOneStep, reuse `BuildPeAtLevel2`, OneStep service check `curStepIdx > 0` → fallback ngay không quan tâm Cấp). Assert: Phase=ChoDuyet (KHÔNG TraLai như Drafter mode) + pointer (0, 1) + SLA NotNull + Changelog **ContextNote** chứa "không lùi được" (Summary field cố định `"Chuyển phase {from} → {to}"`, summary từ ApplyReturnModeAsync chèn vào comment qua line 96-99 service → LogTransition `ContextNote = comment`).

 - **2026-05-15 (S24, Plan M Chunk M3 PASS):** FE rename Phase=TraLai (98) display label "Trả lại" → "Cần chỉnh sửa lại" cho UAT disconnect fix. Spec scope HẸP (display badge label + status reference) tuân thủ strict: 4 file FE × 2 app = 8 edit total. **2 file types/purchaseEvaluation.ts** × 2 app: `PurchaseEvaluationPhaseLabel[98]` (raw phase badge) + `PeDisplayStatusLabel.TraLai` (display status badge — main user-facing). **2 file components/pe/PeWorkflowPanel.tsx** × 2 app: rename 2 inline literal hardcode "Trả lại" trong F1 dialog tooltip (`Phase → "..."`) + confirm message (`Phiếu sẽ về "..."`) — đây là status display reference, KHÔNG phải action verb. Pattern 5 mirror 2 app strict applied. KHÔNG đụng: (1) action button label `← Trả lại` (verb), (2) F1 mode picker label `Trả về Người soạn thảo` (4 mode action), (3) comments narrative line 62/71/etc giữ rationale dev (rule §6.5), (4) `types/contracts.ts` + `types/budget.ts` Phase 98 'Trả lại' — module Contract + Budget khác PE, ngoài scope M3. Verify: `npm run build` fe-admin PASS clean (0 TS err, 9.40s, 1395 KB bundle unchanged trivial) + `npm run build` fe-user PASS clean (0 TS err, 6.92s, 1275 KB). Diff +4/-4 LOC × 2 = 8 LOC tổng trên 4 file. Token ~9k. Decision tactical: 2 chỗ inline literal PeWorkflowPanel rename để giữ UX consistency với badge label sau rename — KHÔNG drift outside spec vì cùng "status display reference" semantics (badge + tooltip + confirm message phải mirror). Anti-fiddle threshold <20% LOC respected.
 
 - **2026-05-14 (S23 t1, K7 Chunk F PASS):** Mig 31 Approver F2 service regression tests. Sub-task 1 fix broken Drafter F2 test reference K1 flagged: `PurchaseEvaluationWorkflowServiceReturnModeTests.cs:253` `drafter.AllowDrafterSkipToFinal = true` (DELETE 3 deprecated Drafter F2 tests entire — `SkipToFinal_DrafterAllowed_SetsPointerToFinalLevel` + `SkipToFinal_DrafterDenied_NonAdmin_Throws` + `SkipToFinal_AdminBypass_Succeeds`, semantic deprecated no value). Sub-task 2 add 3 new Approver F2 tests: `ApproveV2_SkipToFinal_AdminTickFlag_SetsPhaseDaDuyet` (happy path — slot Cấp 1 Bước 1 admin tick → Phase=DaDuyet, pointer cleared, opinion + PEA + Changelog logged), `ApproveV2_SkipToFinal_FlagOff_NonAdmin_ThrowsConflictException` (denied — flag off non-admin slot user → throw "chưa được phép duyệt thẳng Cấp cuối"), `ApproveV2_SkipToFinal_FlagOff_Admin_BypassesFlagCheck` (admin bypass — flag off admin role → DaDuyet allowed). Pattern 11 SeedWorkflowAsync cookie-cutter REUSE — created `SeedApproverF2WorkflowAsync` helper (2 Steps × 2 Levels — multi-step verify skip thẳng terminal KHÔNG fallthrough advance pointer next Step), AllowApproverSkipToFinal per-slot param. PE init Phase=ChoDuyet + CurrentWorkflowStepIndex=0 + CurrentApprovalLevelOrder=1 (vs S22 happy path từ DangSoanThao). Add `using Microsoft.EntityFrameworkCore` cho `.ToListAsync()` PEL/PEA/Changelog query. File header narrative line 17-25 REWRITE để track Mig 31 refactor semantic Approver scope ChoDuyet vs Drafter-from-Nháp cũ.
