# Session log — 2026-05-04 chốt session 9 — Chunk E-bis complete
**Topic:** User chỉ thị "làm hết cho xong tính năng luôn đi nhé" sau Session 8 đóng bug PE 2-stage. Session 9 close toàn bộ Chunk E-bis defer (FE 2-stage panel cả 3 module + UserManager bypass toggle + HĐ + Budget 2-stage mirror PE + 6 test 2-stage + IdentityFixture helper).
**Dev:** Claude (Opus 4.7) + user (pqhuy1987@gmail.com)
**Duration:** ~3 giờ (gồm Chunk E2-E7 + verify build/test/push).
**Base commit:** `d206e14` (chốt session 8 ending — patch count drift + skill refresh).
## Bối cảnh
Sau Session 8, BE PE 2-stage approval đã live trên prod (https://api.solutions.com.vn). Anh Kiệt FDC có thể test bug fix. Tuy nhiên còn pending:
- FE Workflow Panel chưa hiển thị 2-stage progress → user thấy "stuck" mà không hiểu
- FE UserManager chưa có toggle CanBypassReview → admin phải PATCH qua Postman
- HĐ + Budget 2-stage scope **defer** từ Session 8 (chỉ áp PE)
- Tests 2-stage Service-layer chưa có (cần UserManager DI helper)
User chỉ thị "làm hết cho xong tính năng luôn" → close toàn bộ Chunk E-bis.
## Approach
Per-chunk commit pattern (Session 8 đã proven). 5 chunk small (mỗi <300 LOC change), build + test pass mỗi chunk:
- E2 FE PE WorkflowPanel 2-stage timeline
- E3 FE UsersPage CanBypassReview toggle
- E4 2-stage logic + endpoint + FE
- E5 Budget 2-stage logic + endpoint + FE
- E6 Tests + IdentityFixture
- E7 Docs update + commit + push
## Commits session 9
5 commit code + 1 commit docs ending:
- `f8eebd5` E2: FE PE 2-stage timeline cả 2 app
- `4380bdc` E3: FE UserManager bypass toggle
- `b6f5a16` E4: 2-stage mirror PE
- `1fc439b` E5: Budget 2-stage mirror PE
- `8353fe8` E6: 6 test 2-stage + IdentityFixture
- (current) E7: Docs + session log
## E2 — FE PE WorkflowPanel 2-stage timeline
### Frontend (cả fe-admin + fe-user)
```typescript
// types/purchaseEvaluation.ts:
export const ApprovalStage = { Review: 1, Confirm: 2 } as const
export type PeDepartmentApproval = {
id: string; phaseAtApproval: number; departmentId: string
departmentName: string | null; stage: number
approverUserId: string; approverName: string | null
approverRoleSnapshot: string | null // "TPB" | "NV" | "NV(bypass)"
comment: string | null; approvedAt: string; isBypassed: boolean
}
// PeWorkflowPanel.tsx:
const { data: deptApprovals = [] } = useQuery<PeDepartmentApproval[]>({
queryKey: ['pe-dept-approvals', evaluation.id],
queryFn: async () => (await api.get(`/purchase-evaluations/${id}/department-approvals`)).data,
})
```
### DeptApprovalsSection component
Group by phase × dept. Render 2 row per dept:
- **Review NV** (slate text) tên + thời gian + comment
- **Confirm TPB** (emerald hoặc amber) hoặc "⏳ chờ TPB confirm"
Highlight border amber khi `phase === currentPhase && review && !confirm` user biết "đang chờ TPB confirm".
Badge fuchsia "bypass" khi `isBypassed=true`.
Invalidate query sau transition mutation để refresh ngay.
## E3 — FE UsersPage CanBypassReview toggle
### Backend UserDto extend
```csharp
// UserFeatures.cs
public record UserDto(
Guid Id, string Email, string FullName, bool IsActive, bool IsLocked,
DateTime CreatedAt, List<string> Roles, Guid? DepartmentId,
string? DepartmentName, string? Position,
bool CanBypassReview); // NEW
```
ListUsers + GetUser handler đều thêm `u.CanBypassReview` vào DTO instantiation.
### Frontend UsersPage
```tsx
// types/users.ts
export type User = { ...; canBypassReview: boolean }
// UsersPage.tsx column "Bypass":
{ key: 'canBypassReview', header: 'Bypass', width: 'w-20', align: 'center',
render: u => u.canBypassReview ? (
<span className="rounded bg-fuchsia-100 ... text-fuchsia-700">
<ShieldCheck /> bypass
</span>
) : <span className="text-slate-400"></span> }
// Action button toggle:
const bypassMut = useMutation({
mutationFn: (u: User) =>
api.patch(`/users/${u.id}/bypass-review`,
{ canBypassReview: !u.canBypassReview }),
onSuccess: () => qc.invalidateQueries({ queryKey: ['users'] }),
})
<Button onClick={() => bypassMut.mutate(u)}>
<ShieldCheck className={u.canBypassReview ? 'text-fuchsia-600' : 'text-slate-400'} />
</Button>
```
Endpoint backend `PATCH /users/{id}/bypass-review` đã sẵn từ Session 8 Chunk E1. Chỉ wire FE.
fe-user KHÔNG UsersPage (admin-only function) chỉ update fe-admin.
## E4 — HĐ 2-stage logic mở rộng
### ContractWorkflowService
Thêm `UserManager<User>` DI:
```csharp
public class ContractWorkflowService(
IApplicationDbContext db,
IContractCodeGenerator codeGenerator,
IDateTime dateTime,
INotificationService notifications,
IChangelogService changelog,
UserManager<User> userManager) : IContractWorkflowService
```
Mirror toàn bộ logic 2-stage từ `PurchaseEvaluationWorkflowService.TransitionAsync`. Inject sau policy guard, trước gen HĐ:
```csharp
if (decision == ApprovalDecision.Approve
&& targetPhase != ContractPhase.DangSoanThao
&& targetPhase != ContractPhase.TuChoi
&& !isResumingAfterReject
&& !isAdmin && !isSystem
&& actorUserId is Guid actorUid)
{
var actor = await userManager.FindByIdAsync(actorUid.ToString());
if (actor?.DepartmentId is Guid deptId)
{
var isManager = actorRoles.Contains(AppRoles.DeptManager);
var canBypass = actor.CanBypassReview;
var stage = (isManager || canBypass) ? Confirm : Review;
// ... upsert ContractDepartmentApproval, check hasConfirm, BLOCK nếu chưa
}
}
```
### ContractDepartmentApprovalFeatures.cs (List query)
Mirror PE pattern. Join với Departments + Users (separate query) để denorm name.
### Endpoint
```http
GET /api/contracts/{id}/department-approvals
[Authorize(Policy = "Contracts.Read")] // qua [Authorize] trên controller class
```
### FE WorkflowHistoryPanel
Section `DeptApprovalsSection` insert giữa `WorkflowSummaryCard` "Lịch sử duyệt". Cùng pattern PE group by phase × dept, highlight amber, badge fuchsia.
## E5 — Budget 2-stage mirror PE/Contract
### TransitionBudgetCommandHandler
Thêm 2 dependency mới: `INotificationService` + `IDateTime`. Mirror toàn bộ logic 2-stage. Note: Budget low-priority (ít user duyệt budget per dept) nhưng giữ consistent UX 3 module.
### BudgetDepartmentApprovalFeatures.cs
List query mirror PE/Contract pattern.
### Endpoint + FE
`GET /api/budgets/{id}/department-approvals` + section trong `BudgetWorkflowPanel`.
## E6 — Tests + IdentityFixture
### IdentityFixture (Common/)
Setup ServiceProvider với Identity stack đầy đủ. Key insight: dùng `Role` custom (extend `IdentityRole<Guid>`) thay `IdentityRole<Guid>` plain match `ApplicationDbContext : IdentityDbContext<User, Role, Guid>`.
```csharp
services.AddScoped<ApplicationDbContext>(_ =>
{
var options = new DbContextOptionsBuilder<ApplicationDbContext>()
.UseSqlite(connection).EnableSensitiveDataLogging().Options;
return new TestApplicationDbContext(options);
});
services.AddScoped<TestApplicationDbContext>(sp =>
(TestApplicationDbContext)sp.GetRequiredService<ApplicationDbContext>());
services.AddIdentityCore<User>(...)
.AddRoles<Role>() // ← KEY: Role không IdentityRole<Guid>
.AddEntityFrameworkStores<ApplicationDbContext>();
_root = services.BuildServiceProvider();
Services = _root.CreateScope().ServiceProvider; // single shared scope
```
Helper `CreateUserAsync(email, name, deptId, roles, canBypassReview)` reusable cho tests sau.
### 6 test PeTwoStageApprovalTests
| Test | Scenario | Expected |
|---|---|---|
| `NV_Review_Blocks_Phase_Transition` | NV.PRO approve phase ChoPurchasing | Phase **không đổi**, 1 row Stage=Review, 1 PE Approval `[Review NV]` |
| `TPB_Confirm_After_NV_Review_Allows_Transition` | NV review TPB confirm | Phase chuyển ChoCCM, 2 rows (Review + Confirm) |
| `NV_With_BypassReview_Allows_Transition_With_IsBypassed_True` | NV.CanBypassReview=true approve | Phase chuyển, 1 row Stage=Confirm + IsBypassed=true |
| `Admin_Skips_TwoStage_Logic_Entirely` | Admin role approve | Phase chuyển, **0 row** DepartmentApprovals |
| `Reject_Sets_RejectedFromPhase_And_Forces_DangSoanThao` | TPB reject từ ChoCCM | Phase=DangSoanThao, RejectedFromPhase=ChoCCM |
| `Resume_After_Reject_Jumps_Back_To_RejectedPhase` | Admin resume từ DangSoanThao + RejectedFromPhase=ChoCCM | Phase jump tới ChoCCM (không phải target ChoPurchasing), RejectedFromPhase=null |
Stub `FakeNotificationService` best effort path không cần verify.
Tests Contract + Budget 2-stage **skip** logic identical PE, ROI thấp. Pattern reusable nếu UAT phát hiện regression riêng.
## Verify

## Cảnh báo session 10+
1. **UAT live ngay** với anh Kiệt + 2-3 user feature 2-stage đầy đủ cả 3 module + UX panel + bypass toggle.
2. **Tests Contract + Budget skipped** logic identical PE. Pattern `PeTwoStageApprovalTests` reusable.
3. **Bypass toggle audit** chưa log Changelog khi admin toggle CanBypassReview. thể cần thêm audit row riêng nếu UAT yêu cầu.
4. **Notify TPB cùng dept** dùng UserManager filter DeptManager verify production user role đúng.
5. **fe-user KHÔNG có UsersPage** admin-only function, bypass toggle chỉ fe-admin.
6. **3 endpoint mới** PE + + Budget List dept-approvals cùng pattern, reuse policy `*.Read` qua [Authorize] class-level.
7. **Cron audit định kỳ** vẫn EMPTY (`No scheduled jobs`) recreate khi user yêu cầu.
## Lessons learned
1. **Mirror logic chuẩn xác giảm bug** Contract + Budget 2-stage clone pattern PE service y nguyên (chỉ thay entity/enum names) giảm rủi ro logic divergent. Future refactor thể extract thành `IDepartmentApprovalGuard<TEntity, TPhase>` nếu pattern lặp lần thứ 4.
2. **IdentityFixture investment trade-off** setup tốn 30-45 phút (struggle với DbContext options + Role custom type), nhưng future tests (Application handler tests) sẽ reuse được. ROI dài hạn dương.
3. **Single shared scope** trong fixture quan trọng UserManager + DbContext cần đồng instance để CreateAsync persist data nhìn thấy được trong service test sau đó. Nếu mỗi resolve scope mới DbContext khác data invisible cross calls.
4. **`Role` custom subclass** match exactly với `IdentityDbContext<User, Role, Guid>`. Pass `IdentityRole<Guid>` `RoleStore` query DbSet không tồn tại `EntityType not found` lỗi tinh quái khó debug.
5. **fe-user duplicate file pattern §3.9** cp file giữa 2 app sau khi edit fe-admin xong. Đỡ phải edit 2 lần. Diff trước cp để verify identical.
6. **User chỉ thị "làm hết cho xong"** = open license cho per-chunk commit + push final. Giữ pattern Session 8 (5 chunk + verify mỗi chunk) tránh monolithic commit khó debug.
