# Session 2026-04-24 sáng — PE polish: Demo seed + MaPhieu atomic + Pe_* perm defaults

**Context:** Tiếp nối session "[Roles+Demo+Pending cleanup]" (commit a667665) — user yêu cầu
"Chốt lại toàn bộ MD: 'rules, architech, gotcha, skill, daily, hand-off, DB,
luồng DB ...' và làm tiếp đi nhé." → continue PE polish theo STATUS.md §🔥 In
Progress nhóm A (chức năng MISSING trong MVP).

## Tasks completed (4)

### 1. Demo PE data seed — 4 phiếu varied

**File:** `src/Backend/SolutionErp.Infrastructure/Persistence/DbInitializer.cs`

`SeedDemoPurchaseEvaluationsAsync` — pattern mirror `SeedDemoContractsAsync`:

| Phiếu | Type | Phase | Đặc điểm | Quotes |
|---|---|---|---|---|
| `[DEMO]-A-001` | DuyetNcc | DangSoanThao | Drafter mới mở, chưa nhập giá | 0 |
| `[DEMO]-A-002` | DuyetNcc | ChoCEODuyetNCC | Winner đề xuất + 9 quotes 3×3 grid | 9 |
| `[DEMO]-A-003` | DuyetNcc | DaDuyet | Chưa tạo HĐ — showcase kế thừa + PaymentTerms JSON | 4 |
| `[DEMO]-B-001` | DuyetNccPhuongAn | ChoDuAn | 5-step giữa chừng (Procurement đã chuyển) | 9 |

**Idempotent:** skip nếu MaPhieu prefix `[DEMO]` exists. Approval history seed
đúng theo policy A (3-step Procurement→CCM→CEO) hoặc B (5-step
Procurement→PM→CCM→CEO PA→CEO NCC). ApproverUserId mapping đúng role.

**Resolves:** STATUS.md §🔥 A — "Demo PE data seed".

### 2. MaPhieu atomic sequence — Migration 13

**Files mới:**
- `src/Backend/SolutionErp.Domain/PurchaseEvaluations/PurchaseEvaluationCodeSequence.cs` — Prefix PK + LastSeq + UpdatedAt
- `src/Backend/SolutionErp.Application/PurchaseEvaluations/Services/IPurchaseEvaluationWorkflowService.cs` — thêm `IPurchaseEvaluationCodeGenerator` interface
- `src/Backend/SolutionErp.Infrastructure/Services/PurchaseEvaluationCodeGenerator.cs` — impl SERIALIZABLE transaction
- `src/Backend/SolutionErp.Infrastructure/Persistence/Migrations/20260424033449_AddPurchaseEvaluationCodeSequences.cs` — 1 bảng (Prefix nvarchar(100) PK)

**Files modified:**
- `IApplicationDbContext` + `ApplicationDbContext` thêm `PurchaseEvaluationCodeSequences` DbSet
- `PurchaseEvaluationConfiguration` thêm `PurchaseEvaluationCodeSequenceConfiguration` (Prefix max 100)
- `DependencyInjection` register Scoped `IPurchaseEvaluationCodeGenerator → PurchaseEvaluationCodeGenerator`
- `PurchaseEvaluationFeatures` `CreatePurchaseEvaluationCommandHandler` constructor inject codeGen, replace `Random.Shared` với `await codeGen.GenerateAsync(entity, ct)`

**Format:** `PE/{YYYY}/{TypeLetter}/{Seq:D3}` — VD `PE/2026/A/001`, `PE/2026/B/001`.
TypeLetter = `A` (DuyetNcc) | `B` (DuyetNccPhuongAn).

**Pattern mirror:** `ContractCodeGenerator` 1:1 — SERIALIZABLE transaction +
UPDATE-or-INSERT seq row + commit. Race-safe trên multi-instance.

**Resolves:** STATUS.md §🔥 A — "MaPhieu format chính thức".

### 3. Pe_* permission defaults — 7 role × 9 menu key

**File:** `src/Backend/SolutionErp.Infrastructure/Persistence/DbInitializer.cs`

`SeedPurchaseEvaluationPermissionDefaultsAsync` — call cuối
`SeedAdminPermissionsAsync`. Strategy:

| Role | Read | Create | Update | Delete |
|---|---|---|---|---|
| Drafter, DeptManager, Procurement | ✓ | ✓ | ✓ | (chỉ DeptManager) |
| CostControl, ProjectManager, Director, AuthorizedSigner | ✓ | — | ✓ | — |

9 menu key per role: `PurchaseEvaluations` (root) + 2 group (`Pe_DuyetNcc`,
`Pe_DuyetNccPhuongAn`) + 6 leaf (List/Create/Pending × 2). Total ~63 row insert.

**Idempotent:** skip per-(roleId × menuKey) đã có row. Admin tinh chỉnh thêm
qua `/system/permissions`.

**Resolves:** STATUS.md §🔥 B — "Permission grant Pe_*".

### 4. Docs updates

- `docs/STATUS.md` — Phase line 7 "47 DB tables", "13 migrations". Tick `Demo PE data seed`, `MaPhieu format chính thức`, `Permission grant Pe_*`. Add Recently Done row.
- `docs/HANDOFF.md` — TL;DR update, gạch các item ✅ DONE, "47 DB tables" "13 migrations".
- `docs/changelog/migration-todos.md` — Tick 3 task PE.A.
