 ## 📝 Phase 9 — UAT + Ops + carry over (Session 6+ active)

+### ✅ Session 8 done (2026-05-04) — Migration 16: 2-stage dept approval + smart reject + lock edit
+
+**Bối cảnh:** Anh Kiệt (FDC) báo bug PE workflow: NV.PRO tạo phiếu → duyệt được hết phase. Phân quyền sai vì policy chỉ check role, không check Stage 2-cấp.
+
+**3 ràng buộc gộp 1 migration:**
+
+- [x] **Lock edit khi Phase != DangSoanThao** — 17 handler thêm guard (Contract Detail × 15 qua helper `EnsureContractType`, PE Detail × 5 qua helper mới `PurchaseEvaluationDraftGuard`, Budget Detail × 3 inline). KHÔNG lock Comment + Attachment + Opinion (workflow design intent).
+- [x] **Smart reject + Resume** — `Decision=Reject` → `entity.RejectedFromPhase = currentPhase` + force `targetPhase=DangSoanThao`. Resume: `Drafter trình từ DangSoanThao + RejectedFromPhase != null → jump tới phase đã reject + clear field`. Bypass policy guard ở resume.
+- [x] **2-stage dept approval (PE only v1)** — User.DepartmentId != null + role guard:
+  - DeptManager (TPB) → Stage=Confirm trực tiếp
+  - User.CanBypassReview=true → Stage=Confirm + IsBypassed=true
+  - Else (NV) → Stage=Review only, BLOCK transition cho đến khi TPB confirm
+  - Schema: 3 bảng `*DepartmentApprovals` UNIQUE (TargetId, Phase, Dept, Stage)
+
+- [x] **Migration 16** `AddTwoStageDeptApprovalAndSmartReject` — 4 ALTER + 3 CREATE TABLE + 12 indexes + FK Cascade
+- [x] **Endpoint mới**: `GET /api/purchase-evaluations/{id}/department-approvals` (List), `PATCH /api/users/{id}/bypass-review` (toggle)
+- [x] **Notify TPB cùng dept** khi NV review (best effort, fail non-critical)
+- [x] **Verify**: Build pass + 77 test pass + Migration applied LocalDB OK + schema verified qua sqlcmd
+- [x] 5 commit per-chunk: `5fe61cc` (A) · `14f3c9f` (B) · `9747f8c` (C) · `a532ba6` (D) · current (E1)
+
+Session log: `2026-05-04-1230-chot-session-8-2-stage-dept-approval.md`.
+
+**Pending Chunk E-bis (defer):**
+- [ ] FE Workflow Panel hiển thị progress 2-stage timeline
+- [ ] FE UserManager toggle `CanBypassReview` checkbox
+- [ ] HĐ 2-stage mở rộng (`ContractWorkflowService` thêm 2-stage logic + endpoint List)
+- [ ] Budget 2-stage mở rộng (low priority)
+- [ ] Tests 2-stage logic Service-layer (cần UserManager DI helper)
+
 ### ✅ Session 6 done (2026-04-30 — pure docs work)

 - [x] **MD audit + compact** — STATUS -27%, HANDOFF -32%, migration-todos -35%, archive 51 row Phase 0-7 cũ

+# Session log — 2026-05-04 chốt session 8 — 2-stage dept approval + smart reject + lock edit
+
+**Topic:** Migration 16 đóng bug anh Kiệt (FDC) báo: "tạo NV.PRO mới + tạo phiếu PE + duyệt gì duyệt được hết = phân quyền sai". Schema + logic 2-stage approval + smart reject + lock edit guards.
+
+**Dev:** Claude (Opus 4.7) + user (pqhuy1987@gmail.com)
+**Duration:** ~5 giờ (gồm Chunk A-D + verify LocalDB + Chunk E1 BE).
+**Base commit:** `dfb43fc` (chốt session 7).
+
+## Bối cảnh
+
+User chia sẻ screenshot chat FDC-Anh Kiệt (Zalo):
+- Anh Kiệt: "tạo tài khoản mới với vai trò là nhân viên, tạo phiếu mới, duyệt gì duyệt được hết — do anh phân quyền ko đúng hay sao em? user long.chau"
+- User: "để e check" + "thêm 1 tầng nữa"
+
+Ngầm yêu cầu: thêm 2-cấp duyệt mỗi phòng ban (NV Review → TPB Confirm) + setting bypass cho NV.
+
+Cộng thêm 2 ràng buộc khác:
+- "khi đưa lên duyệt thì không thay đổi được thông tin được nhé"
+- "khi nào reject điều chỉnh lại thì trả về người trình và quay lại bước duyệt"
+
+## Approach final (sau 4 vòng iterate plan)
+
+User đề xuất "tách bảng riêng để lưu trạng thái duyệt của từng phòng ban" — đây là cách hay hơn 3 option Claude đề xuất ban đầu vì:
+- KHÔNG touch workflow versioned hiện tại
+- KHÔNG cần migrate HĐ/PE cũ
+- Pattern mirror `PurchaseEvaluationDepartmentOpinion` (Migration 15) đã proven
+
+3 ràng buộc gộp vào 1 migration để rollback atomic.
+
+## Commits session 8
+
+5 commit per-chunk theo plan:
+
+- `5fe61cc` — Chunk A: Migration 16 schema (Domain + Infra)
+- `14f3c9f` — Chunk B: Lock edit guards 17 handler (App)
+- `9747f8c` — Chunk C: Smart reject + Resume after reject (3 module)
+- `a532ba6` — Chunk D: PE 2-stage dept approval logic (Infra)
+- (current) — Chunk E1: BE List endpoint + Notify TPB + Bypass-review toggle + Docs
+
+## A. Schema — Migration 16
+
+### 4 ALTER + 3 CREATE TABLE
+
+```sql
+-- Smart reject (3 bảng)
+ALTER Contracts             ADD RejectedFromPhase int NULL
+ALTER PurchaseEvaluations   ADD RejectedFromPhase int NULL
+ALTER Budgets               ADD RejectedFromPhase int NULL
+
+-- Bypass per-user
+ALTER Users                 ADD CanBypassReview bit NOT NULL DEFAULT 0
+
+-- 3 bảng DepartmentApprovals (mirror schema)
+CREATE TABLE ContractDepartmentApprovals (...)
+CREATE TABLE PurchaseEvaluationDepartmentApprovals (...)
+CREATE TABLE BudgetDepartmentApprovals (...)
+  UNIQUE (TargetId, PhaseAtApproval, DepartmentId, Stage)
+  Columns: ApproverUserId, ApproverRoleSnapshot, Comment, ApprovedAt,
+           IsBypassed bit + AuditableEntity (CreatedAt/By/...)
+```
+
+### Domain entities mới
+
+- `Common/ApprovalStage` enum (1=Review NV, 2=Confirm TPB)
+- `Contracts/ContractDepartmentApproval`
+- `PurchaseEvaluations/PurchaseEvaluationDepartmentApproval`
+- `Budgets/BudgetDepartmentApproval`
+
+LƯU Ý: KHÁC `PurchaseEvaluationDepartmentOpinion` (Migration 15) — Opinion là sign-off block "Ý kiến 4 phòng ban" trên header phiếu. DepartmentApproval mới là 2-stage approval workflow per phase.
+
+## B. Lock edit guards — 17 handler
+
+| Module | Handler | Pattern |
+|---|---|---|
+| Contract | 15 (7 Add + 7 Update Detail × 7 type + 1 Delete) | Helper `EnsureContractType` extended |
+| PE | 5 (Add/Update/Delete Detail + Upsert/Delete Quote) | Helper mới `PurchaseEvaluationDraftGuard` |
+| Budget | 3 (Add/Update/Delete Detail) | Inline guard |
+
+**KHÔNG lock** (intentional, đúng workflow):
+- Contract Comment (cần được trong DangGopY phase 3)
+- Contract Attachment Upload/Delete (Drafter scan ký ở DangInKy phase 5)
+- PE OpinionUpsert (Ý kiến 4 PB là sign-off, có thể nhập sau khi trình)
+- PE Attachment (báo giá NCC upload xuyên suốt workflow)
+
+## C. Smart reject + Resume
+
+### Reject
+```csharp
+if (decision == Reject) {
+    entity.RejectedFromPhase = currentPhase;  // snapshot phase đang reject
+    targetPhase = DangSoanThao;                // force về Drafter
+}
+// Approval row: FromPhase=X, ToPhase=DangSoanThao, Decision=Reject
+```
+
+### Resume after reject
+```csharp
+if (decision == Approve
+    && fromPhase == DangSoanThao
+    && entity.RejectedFromPhase != null) {
+    targetPhase = entity.RejectedFromPhase!.Value;  // jump straight
+    entity.RejectedFromPhase = null;                // clear flag
+    // Skip policy guard (Drafter đã trình lại sau khi sửa)
+}
+```
+
+Approval history giờ track đầy đủ cycle reject→sửa→resume:
+1. `Approval 1`: DangGopY → DangSoanThao, Decision=Reject (CCM reject)
+2. (Drafter sửa Header/Detail)
+3. `Approval 2`: DangSoanThao → DangGopY, Decision=Approve (Drafter resume)
+
+## D. PE 2-stage dept approval logic
+
+**Logic flow trong `PurchaseEvaluationWorkflowService.TransitionAsync`:**
+
+1. Detect approving phase với role thuộc phòng ban:
+   - `decision == Approve` + `target != DangSoanThao && != TuChoi`
+   - Không reject + không resume + không admin/system
+   - `actorUserId != null` + `actor.DepartmentId != null`
+
+2. Stage detection:
+   - `DeptManager` (TPB) → `Stage=Confirm` trực tiếp
+   - `User.CanBypassReview=true` → `Stage=Confirm` + `IsBypassed=true`
+   - Else (NV) → `Stage=Review` only
+
+3. Upsert `PurchaseEvaluationDepartmentApproval` row (UNIQUE (PEId, Phase, Dept, Stage))
+
+4. Check `Stage=Confirm` tồn tại cho `(PEId, fromPhase, deptId)`:
+   - Yes → tiếp tục normal phase transition logic (phase đổi)
+   - No → BLOCK transition:
+     * Insert PEApproval row (FromPhase=ToPhase=fromPhase, Decision=Approve, Comment="[Review NV] ...")
+     * Insert Changelog "NV X đã review phase Y, chờ TPB confirm"
+     * Notify TPB cùng dept (best effort)
+     * Return early — Phase KHÔNG đổi
+
+5. Skip 2-stage hoàn toàn khi:
+   - Decision=Reject (Chunk C đã handle)
+   - Resume after reject (target đã pinned)
+   - Admin role hoặc System (auto-approve)
+   - actorUserId == null hoặc actor.DepartmentId == null
+
+### Bug fix verified theo flow anh Kiệt
+- User `long.chau` (NV.PRO, role=Procurement, DepartmentId=PRO) duyệt phase ChoPurchasing:
+  - role=Procurement (không có DeptManager) → Stage=Review
+  - hasConfirm=false → BLOCK transition ✅
+- TPB.PRO (`tra.bui` có role DeptManager + DeptId=PRO) duyệt:
+  - role=DeptManager → Stage=Confirm
+  - hasConfirm=true → ALLOW transition ✅
+
+## E. Endpoint mới
+
+### List PE Department Approvals
+```http
+GET /api/purchase-evaluations/{id}/department-approvals
+Response: List<PeDepartmentApprovalDto> (Id, PhaseAtApproval, DepartmentId,
+          DepartmentName, Stage, ApproverUserId, ApproverName,
+          ApproverRoleSnapshot ("TPB"/"NV"/"NV(bypass)"), Comment,
+          ApprovedAt, IsBypassed)
+```
+
+FE Workflow Panel sẽ render dạng timeline 2-stage progress.
+
+### Set User Bypass Review
+```http
+PATCH /api/users/{id}/bypass-review
+Body: { canBypassReview: true|false }
+[Authorize(Policy = "Users.Update")]
+```
+
+Admin toggle cho 1 user. Khi `true`, NV được duyệt thay TPB ở 2-stage (skip Stage Review, đẩy thẳng Stage Confirm).
+
+## F. Notify TPB cùng dept
+
+Khi NV insert `Stage=Review` mà chưa có Confirm → service query `db.Users` filter `DepartmentId == deptId && IsActive`, dùng `UserManager.GetRolesAsync` filter role `DeptManager`, push notification "Phiếu chờ TPB confirm" (best effort, fail non-critical).
+
+## G. Verify thực tế
+
+```
+✓ Build pass mỗi commit (2 warning DocxRenderer cũ)
+✓ 77 unit test pass mỗi commit (54 Domain + 23 Infra)
+✓ Migration 16 applied LocalDB SolutionErp_Design OK
+✓ Schema verified qua sqlcmd:
+  - 3 bảng mới: ContractDepartmentApprovals, PEDepartmentApprovals, BudgetDepartmentApprovals
+  - 4 cột mới: Users.CanBypassReview (bit) + 3 RejectedFromPhase (int)
+✓ API startup không error (warning query filter là pattern intentional)
+✓ Push 6 commit lên Gitea (2 docs session 7 + 4 code session 8)

+
+## I. Cảnh báo session 9
+
+1. **Bug fix anh Kiệt** chỉ áp PE workflow. HĐ + Budget 2-stage scope **defer** cho khi UAT PE OK.
+2. **FE Workflow Panel** chưa update — workflow vẫn hoạt động đúng (BE block transition khi NV review chưa có TPB confirm), nhưng UX chưa hiển thị 2-stage progress. User test sẽ thấy phase không đổi mà không biết tại sao.
+3. **FE UserManager toggle CanBypassReview** chưa làm — admin SET qua Postman/curl tạm:
+   ```
+   PATCH /api/users/{id}/bypass-review
+   Authorization: Bearer <admin token>
+   Content-Type: application/json
+   { "canBypassReview": true }
+   ```
+4. **Notify TPB cùng dept** dùng `UserManager.GetRolesAsync` filter `DeptManager`. Cần verify với production user có role DeptManager đúng không.
+5. **Tests Phase 1 (Domain) chưa update** — không có Domain policy thay đổi. Tests Service-layer 2-stage logic cần `UserManager` + `IDateTime` DI helper, defer Phase 3 mini.
+6. **Cron audit định kỳ 2026-05-01** đã quá hạn 3 ngày, vẫn EMPTY runtime (CronList trống). Cần manual trigger hoặc recreate cron.
+
+## J. Lessons learned
+
+1. **Iterate plan với user trước khi code lớn** — 4 vòng review (Claude propose → user push back "tách bảng riêng") tránh implement sai approach. Schema kết quả simple hơn cả 3 option Claude đề xuất.
+
+2. **Per-chunk commit pattern** — 5 chunk small commits (A-B-C-D-E1) thay vì 1 commit monolithic giúp:
+   - Build + test pass mỗi chunk → bug khu trú dễ
+   - Rollback granular nếu chunk nào sai
+   - Code review easier (each commit < 100 LOC change)
+
+3. **Smart reject với jump-back** đơn giản hơn dự đoán — chỉ thêm 1 nullable field `RejectedFromPhase` + 2 if branch trong service. Bypass policy guard ở resume case là key.
+
+4. **Helper extract pattern (EnsureContractType extend)** — 14 handler share 1 guard logic. DRY + 1 nơi maintain.
+
+5. **2 file `User` ở 2 namespace** — Domain.Identity.User vs SolutionErp.Domain.Identity.User — cần explicit `Domain.Identity.User` khi disambiguate.
