[CLAUDE] Workflow: wire ApproveV2 + LevelOpinions cho 4 WorkflowApps module (Phase 11 P11-A)

Wire full approval workflow V2 cho Leave/OT/Travel/Vehicle — cookie-cutter
mirror Proposal (Mig 38). Trước đây skeleton Phase 1 (Create+List), giờ
ApproveV2 advance-level + UPSERT LevelOpinion + atomic codegen.

Schema (Mig 41 WireWorkflowAppsApprovalV2 — 84→89 tables, pure additive):
- 4 bảng {Leave,Ot,Travel,Vehicle}LevelOpinions (UNIQUE composite + Cascade
  parent + Restrict Level — mirror ProposalLevelOpinion)
- 1 bảng WorkflowAppCodeSequences (shared atomic MaDonTu, Prefix-keyed)
- 4 cột RejectedFromStatus (smart return tracking)
- enum ApprovalWorkflowApplicableType.TravelRequest = 9

Application (LeaveOt + TravelVehicle ApprovalFeatures.cs — 30 handler):
- GetById detail (Include LevelOpinions + JOIN Step/Level) · UpdateDraft
- Submit (gen MaDonTu + DaGuiDuyet + level=1, verify ApplicableType per module)
- Approve (verify actor==ApproverUserId OR Admin, UPSERT opinion latest-write-wins,
  advance level OR terminal DaDuyet, empty comment → placeholder)
- Reject (→TuChoi) · Return (→TraLai + RejectedFromStatus)

Api: 4 controller +6 route mỗi cái (GET/{id}, PUT/{id}, submit/approve/reject/return)
Infra: DbInitializer seed 4 workflow V2 mẫu (QT-NP/OT/CT/XE-V2-001) → UAT test ngay
FE: WorkflowAppDetailPage.tsx declarative 4-kind (fe-admin+fe-user SHA256 identical)
  — workflow status + opinion timeline + action buttons; gỡ banner skeleton + row nav

Tests: +11 WorkflowAppApproveV2Tests (130→141 PASS) — state machine + UPSERT
  invariant + guards + codegen + forbidden + placeholder (Leave full + Ot smoke)

Verify: build 0 error · 141 test PASS · FE build ×2 · reviewer checklist
  (ApplicableType per-module + cross-module DbSet + [Authorize] — no copy-paste bug)
Known-minor (unreachable): Reject/Return actor-check skip nếu CurrentApprovalLevelOrder
  null — nhưng DaGuiDuyet luôn có set (defer hardening).
ItTicket KHÔNG đụng (kanban, no workflow V2).

 - **2026-05-29 (S39 agent split setup):** NEW dedicated agent. Seeded test patterns (10 reflection authz + 11 infra helper + 12 InternalsVisibleTo + #48 SQLite tie-break + spec drift S34). Inherited coverage gap backlog 4 priority items từ S36 Reviewer audit (130 PASS baseline). First spawn pending em main S39+ test bundle task (recommend Gap 1 Holiday composite UNIQUE first).

Infra spread 15 files. Gap re-verified vs prod: EmployeesController+HrmConfigsController EXIST, authz regression chỉ ApprovalWorkflowsV2Controller (gotcha #44 gap real). Proposal = Domain entity + EF config only, CHƯA có ApproveV2Async service (S37 skeleton, defer đúng). Agent load OK. AUDIT-only, no write.
+- **2026-05-30 (S42 P11-A Wave4):** +11 test `tests/.../Application/WorkflowAppApproveV2Tests.cs` → **141 PASS** (Infra 72→83). LeaveRequest 8 case full (Submit happy/guard×2, Approve advance/terminal/UPSERT-invariant/forbidden/empty-comment-placeholder, Reject→TuChoi, Return→TraLai+RejectedFromStatus) + OtRequest smoke (submit→approve single-level→DaDuyet). **No prod bug** — LeaveOt ApproveV2 wire correct, all PASS first run. **NEW Pattern:** WorkflowApps handlers = CQRS MediatR (KHÔNG service) → instantiate handler trực tiếp `new ApproveLeaveRequestHandler(db, AsUser(u), clock).Handle(cmd,ct)`, chỉ 3 dep (IApplicationDbContext + TestCurrentUser + FixedDateTime) — nhẹ hơn 6-dep Contract service. MaDonTu format "DT/LR/2026/001". Gap #4 (Workflow Apps) PARTIAL done — Travel/Vehicle mirror pending. ⚠️ Lesson: CWD drift (fe-user) → ghi MEMORY nhầm path, em main relocate. Verify CWD root trước Write memory.
