[CLAUDE] FE-Admin+Docs: Contract workflow N-stage Designer mirror PE + Docs (Chunk F)

FE Admin WorkflowsPage Designer extend mirror PeWorkflowsPage:
- Type InnerStepDto + extend StepDto +innerSteps
- Type EditInnerStep + extend EditStep +innerSteps
- copyFromDefinition include innerSteps map
- Default new step +innerSteps:[]
- departmentsList useQuery
- Save mutation payload include innerSteps Order asc
- UI sub-section "Cấp duyệt nhỏ trong phòng" drag-list per step card với
  Phòng × Cấp + required checkbox + button "+ Thêm cấp duyệt" emerald
- Empty state hint fallback 2-cấp legacy

KHÔNG đụng fe-user — WorkflowsPage admin-only.

Reuse PositionLevel const + Label maps từ Session 12 types/users.ts.

Docs:
- STATUS.md Last updated + Phase summary (19→20 mig, 89→95 test, 56→57
  bảng) + 1 row Recently Done Session 13 (KEEP narrative cũ)
- HANDOFF.md TL;DR Session 13 prepend + 7 cảnh báo Session 14+
- migration-todos.md Phase 9 + Session 13 block 5 chunk
- Session log NEW `2026-05-07-2400-n-stage-contract-mirror.md` đầy đủ
  rationale + per-chunk + bug log

Defer cron audit 2026-06-01: schema-diagram §17 Mig 20, skill
ef-core-migration row, skill contract-workflow N-stage cross-ref.

🎉 SESSION 13 COMPLETE: Mirror N-stage Contract module (Mig 20). 5
commit per-chunk + skip Chunk E auto-bind. Total 95 test pass.
Backward compat 100% với 2-stage Mig 16 legacy.

Pending Task 4: Wire BE TraLai PE transition + Task 2: Sample data seed.

Budget defer (cần versioned WF migration trước, hardcoded BudgetPolicy hiện tại chưa có WorkflowDefinition). 5 chunk per-commit (build + ef + test pass mỗi chunk): **Chunk A (`951ffa3`)** Domain entity `WorkflowStepInnerStep` (Domain/Contracts/) + nav WorkflowStep.InnerSteps + ALTER ContractDepartmentApproval.InnerStepId Guid? + EF config FK Cascade Step / Restrict Dept+InnerStep + **Migration 20** `AddContractWorkflowInnerStepsAndAlterDeptApprovalUnique` GỘP 1 (CREATE TABLE WorkflowStepInnerSteps + ALTER InnerStepId + DropIndex old + Recreate filtered legacy `WHERE InnerStepId IS NULL` + new filtered N-stage `WHERE InnerStepId IS NOT NULL` + 3 IX + 3 FK). **Chunk B (`04cf2a0`)** Application CQRS DTO — `WorkflowStepInnerStepDto` + extend `WorkflowStepDto` + GetWorkflowAdminOverview Include InnerSteps + DeptNames map + `CreateWorkflowStepInnerStepInput` + `CreateWorkflowStepInput` extend (default null backward compat) + Validator child rules + Handler atomic batch insert. **Chunk C (`e247b67`)** ContractWorkflowService refactor mirror PE — load definition InnerSteps eager, reject branch clear N-stage rows tại fromPhase, dept approval block split hasInnerSteps→N-stage logic / else→legacy 2-stage. N-stage flow giống PE: yêu cầu actor có DeptId+PositionLevel, match firstPending Order asc + (exact level OR canBypass + level≥), exact upsert 1 row InnerStepId, bypass batch upsert NV+PP+TP cùng dept ≤ actor (audit IsBypassed cho cấp dưới), recheck stillPending → BLOCK + log "duyệt cấp X (còn Y pending)". **Chunk D (`7c0772a`)** Tests 6 N-stage Contract mirror PE pattern + helper SeedWorkflowDefinitionAsync 2 step adjacent (DangGopY + DangDamPhan) + SeedContractAsync với Project + Supplier seed + FakeChangelogService + FakeContractCodeGenerator stubs.

Total 89 → **95 test pass**. **Chunk E SKIP** — WorkflowsController auto-bind `[FromBody] CreateWorkflowDefinitionCommand` record qua JSON, no code change cần. **Chunk F (current)** FE-Admin types/users.ts đã có PositionLevel const từ Session 12 reuse.

Spec defaults chốt 6 câu (PositionLevel int 1=NV/2=PP/3=TP, sequential pure, bypass cùng dept TP skip NV+PP, smart reject reset N-stage rows về DangSoanThao, PE-only first, designer 1 sub-section InnerSteps). 6 chunk per-commit (build + ef + test pass mỗi chunk per `feedback_per_chunk_commit.md`): **Chunk A (`13ab533`)** Domain enum `PositionLevel` (NV/PP/TP) + entity `PurchaseEvaluationWorkflowStepInnerStep` + ALTER User.PositionLevel int? + ALTER PEDeptApprovals.InnerStepId Guid? + EF config + **Migration 18** `AddPeWorkflowInnerStepsAndPositionLevel` (1 CREATE TABLE + 2 ALTER + 3 index + FK Cascade Step / Restrict Dept/InnerStep). 3-file rule. **Chunk B (`0e56bd0`)** Application CQRS DTO — `PeWorkflowStepInnerStepDto` + extend `PeWorkflowStepDto` + `CreatePeWorkflowStepInnerStepInput` (default null backward compat existing PeWorkflowAdminTests) + Validator child rules + Handler atomic batch insert + UserDto +PositionLevel field + `SetUserPositionLevelCommand` mirror SetBypassReview. **Chunk C (`0c62e24`)** Service N-stage logic — **Migration 19** `AlterPeDeptApprovalsUniqueFilteredForInnerSteps` (filtered unique: legacy `WHERE InnerStepId IS NULL` + N-stage `WHERE InnerStepId IS NOT NULL`) cho phép multi-row cùng dept khác inner step. PurchaseEvaluationWorkflowService refactor: load definition InnerSteps eager + reject branch clear N-stage rows + dept block split hasInnerSteps→N-stage logic / else→legacy 2-stage.

Backward compat: workflow no InnerSteps fallback legacy + InnerStepId=null filter unique cũ vẫn enforce. **Chunk D (`3d76c6b`)** Tests N-stage 6 test mới (NV first blocks / 3-level sequential pass / TP bypass skips / wrong dept throws 403 / reject clears rows / legacy fallback no inner) + IdentityFixture extend `+positionLevel` arg + helper SeedWorkflowDefinitionAsync 2 step adjacent (ChoPurchasing+ChoCCM) cho FromDefinition build transition policy guard pass.

FE toggle "Nhập tay" trong PeHeaderForm + ContractCreatePage NewForm/EditForm × 2 app (5 commit). **B3 (S11+) BudgetFieldRow inline editor** — Section 2 "b. Ngân sách" thay FormRow tĩnh → editable component (toggle + Select OR 2 input + Save dirty + Hủy). canEdit cho cả 3 view (Workspace/Danh sách/Duyệt mode), readOnly chỉ display (3 commit). **B4 (S11++) InfoTab inline edit + PeListPanel pencil hover** — Section 1 "✎ Sửa" button flip display↔inputs (Tên/Địa điểm/Mô tả/Payment editable, Dự án locked). PeListPanel thêm pencil icon group-hover absolute right + URL `?editHeader=1` chain → `autoEditHeader` prop trigger mount-time edit (3 commit). **B5 (S11+++) Workspace "new" sectioned create view** — `PeWorkspaceCreateView.tsx` ~230 LOC layout 5 sections giống PeDetailTabs visual. S1 + S2.b editable, S3-5 LockedHint "Lưu phiếu trước". POST trigger create. Replace `PeHeaderForm` trong workspace mode='new' (1 commit). **B6 (S11++++) Danh sách disable toàn bộ interactions** — PurchaseEvaluationsListPage `readOnly={true}` hardcoded cho PeDetailTabs + `readOnly={!pendingMe}` cho PeWorkflowPanel (List view → ẩn Chuyển tiếp + show hint "Vào menu Duyệt"; Pending vẫn approve được) (2 commit). **B7 (S11+++++) Lock Loại quy trình + payment preset** — workspace `<Select>` Loại quy trình → `<Input disabled>` theo URL `?type=N`. `<Textarea>` JSON Điều khoản TT → `<Select>` 8 preset Việt + "Khác (nhập tay)" → text input fallback (1 commit). **B8 (S11++++++) Display status meta** — `PeDisplayStatus` enum 4-5 trạng thái UI (Bản nháp / Đã gửi duyệt / Trả lại / Đã duyệt / Từ chối) gom phase chi tiết. `getPeDisplayStatus()` helper. Workflow timeline Panel 3 vẫn giữ phase chi tiết (1 commit). **B9 (S11+++++++) Phase TraLai + pencil always visible + edit gating** — Domain `PurchaseEvaluationPhase` thêm `TraLai = 98` (giữa DaDuyet=7 + TuChoi=99). FE label/color + display status badge. `isEditablePhase()` helper: chỉ DangSoanThao + TraLai. PeListPanel pencil bỏ hover-only → LUÔN visible (bright khi editable / xám disabled khi không) + click guard. Workspace `editableOnly` filter client-side (1 commit). **B10 (hotfix CI)** — TS strict catch fail 2 commit B7+B8 do skip-verify (`forcedPhase` rename quên xóa destructuring args + unused `PurchaseEvaluationType` import). Update memory `feedback_uat_skip_verify.md` thêm exception "rename/remove → BẮT BUỘC `npm run build`" (1 commit). **B11 (last) PE detail polish** — `NccSelectorRow` Section 2.a thay FormRow tĩnh → Select dropdown từ ev.suppliers (Section 3 list) wire `/select-winner` API. Section 2.c text rõ "(chọn NCC trước)" / "(chưa nhập báo giá)". Section 3 row khi `isWinner` → ẩn ✏ + 🗑 (chỉ giữ ✓ active). Bottom action bar workspace mode: **2 nút "Lưu (đóng)" + "Lưu & Gửi Duyệt →"** confirm dialog → POST `/transitions` với `targetPhase = first nextPhase` skip TuChoi/TraLai → workflow chuyển từ Bản nháp/Trả lại → Đã gửi duyệt (ChoPurchasing) → onBack đóng workspace (1 commit). | `ee0d360` (S10 C1) → `4c0625c` (B11) — 23 commit total |
