 # HANDOFF — Brief 5 phút cho session tiếp theo

-**Last updated:** 2026-04-28 (Phase 7 — **Module Ngân sách (Budget) BE + 14 demo users Solutions thật**)
+**Last updated:** 2026-04-29 (Phase 8 — **Budget FE complete + PE/HD-Budget integration + PE Workflow Designer + Ý kiến 4 PB + Tests Phase 1-2 + CI gate**)

 ## TL;DR

-**Session 4 (28/04)** thêm 2 milestone lớn:
+**Session 5 (29/04)** đóng gần hết feature gap + bật test gate:
+
+### 🎯 Headline outcomes
+- ✅ **Budget feature-complete** — FE 3-panel pages cả 2 app, BE đã sẵn từ session 4
+- ✅ **PE/HD ↔ Budget integration** — form select Budget filter Phase=DaDuyet + Project, cột "So với ngân sách" ở PE matrix với delta indicator
+- ✅ **PE Detail UI restructure** match form chính thức PHIẾU TRÌNH KÝ (4 section đánh số)
+- ✅ **PE Workflow Designer admin UI** `/system/pe-workflows/:typeCode` versioned với clone/edit/+Role/+User
+- ✅ **Ý kiến 4 phòng ban** — migration 15 + section sign-off 2x2 grid (Phê duyệt/CCM/MuaHàng/SM-PM)
+- ✅ **Tests Phase 1-2** — 71 unit test pass + CI gate fail-fast (Domain policy + Infra code generator)
+
+**Session 4 (28/04)** đã có:

 ### A. Module Ngân sách (Budget) BE — migration 14, +4 bảng, +11 endpoint

@ -24,25 +34,23 @@
 - Pwd `User@123456`. Reconcile pattern (gotcha #38 4-field rename).
 - Tổng 30 user (16 sample cũ giữ + 14 Solutions thật mới).

-**Tổng:** 51 DB tables, ~124 endpoints, 14 migrations, 38 gotchas, 5+ commit
-session 4 push lên Gitea.
+**Tổng cumulative:** 52 DB tables, ~128 endpoints, 15 migrations, 38 gotchas,
+**71 unit test**, 6 commit session 5 push lên Gitea.

-## ⚠️ CẢNH BÁO session tiếp (Session 5)
+## ⚠️ CẢNH BÁO session tiếp (Session 6)

-1. **FE Budget pages CHƯA LÀM** — BE đã sẵn sàng nhưng chưa có page nào. Pattern: copy từ PE 3-panel List + Create + Detail tabs (Thông tin / Hạng mục) + WorkflowPanel timeline. Mirror sang fe-user. Thêm route `/budgets`, `/budgets/new`, `/budgets/:id`. Menu resolver `Bg_*` → URL.
-2. **PE/Contract → Budget integration CHƯA WIRE** — BE đã có `BudgetId?` nullable FK trên cả 2 entity, FE form chưa thêm field "Ngân sách" select. Cần filter Budget theo `Phase=DaDuyet && NamNganSach=current && ProjectId match`. Tab Hạng mục có thể bonus cột "So với ngân sách".
+1. **CI test gate active** — mỗi commit push trigger 2 step `dotnet test` (Domain + Infrastructure) TRƯỚC build/deploy. Test fail = NO deploy. Khi feature mới có bug logic → thêm regression test trước khi commit. Workflow: code → `dotnet test SolutionErp.slnx` local → commit → push.
+2. **Login email** `admin@solutionerp.local` / `Admin@123456` — domain default
+   chưa đổi sang `@solutions.com.vn` (chỉ demo user rebrand qua BackfillDemoEmail).
 3. **Chưa xóa binding cũ `.huypham.vn`** — vẫn active fallback. Sau 1-2 ngày
   verify stable → `.\migrate-domains.ps1 -RemoveOld -SkipCert` trên VPS.
 4. **win-acme scheduled task "unhealthy"** — cert auto-renew có thể fail
   khi gần 2026-06-18. Fix: mở `wacs.exe` interactive → Manage Renewals →
   recreate task.
-5. **PE feature gap carry over** (xem STATUS §C):
-   - PE Workflow admin designer UI `/system/pe-workflows/:typeCode`
-   - Section "Ý kiến 4 phòng ban" (Phê duyệt/CCM/MuaHàng/SM-PM)
-   - Export phiếu PDF/Excel
-6. **Login email** `admin@solutionerp.local` / `Admin@123456` — domain default
-   chưa đổi sang `@solutions.com.vn` (chỉ demo user và rebrand cũ trong BackfillDemoEmail).
-7. **Chú ý G-084:** VPS shared với VietReport — mọi reverse proxy / backend
+5. **Export phiếu PDF/Excel PE** — pending vô thời hạn (user nói không quan trọng lắm). Khi cần: tái dùng `IDocumentConverter` + template `PE-TrinhDuyet.docx`.
+6. **Atomic sequence Budget chưa chốt** — `NS-YYYYMM-XXXX` Random.Shared. Khi format chốt → migration `AddBudgetCodeSequences` + `IBudgetCodeGenerator` SERIALIZABLE pattern (mirror Contract/PE).
+7. **Versioned workflow Budget chưa có** — hardcoded `BudgetPolicy.Default` 3-step. Khi user cần admin config UI → migration `AddBudgetVersionedWorkflow` + 3 bảng + pin per Budget.
+8. **Chú ý G-084:** VPS shared với VietReport — mọi reverse proxy / backend
   service mới phải dùng `127.0.0.1` + bind loopback IPv4 explicit.

 ## Cần làm kế tiếp

-### 🔥 Priority 0 — Budget FE + PE/HD integration (session 5)
+### 🔥 Priority 0 — Session 6 (Ops + UAT focus)

-Xem **STATUS.md §🔥 In Progress** đầy đủ (nhóm A/B/C/D/E). Tóm tắt:
+Đa số feature gap đã đóng. Còn lại chủ yếu Ops/UAT + optional polish.

-**A. Budget FE pages — copy pattern PE:**
-1. `fe-admin/src/types/budget.ts` (types + enums BudgetPhase + ApprovalDecision reuse)
-2. `fe-admin/src/pages/budgets/BudgetsListPage.tsx` (3-panel `lg:grid-cols-[320px_1fr_360px]` — Panel 1 list + Panel 2 detail tabs + Panel 3 workflow timeline)
-3. `fe-admin/src/pages/budgets/BudgetCreatePage.tsx` (form Header: tên/năm/dự án/phòng ban/người soạn)
-4. `fe-admin/src/components/budgets/BudgetDetailTabs.tsx` (Thông tin / Hạng mục — flat row giống PE Details)
-5. `fe-admin/src/components/budgets/BudgetWorkflowPanel.tsx` (Panel 3: timeline phase + ô comment + button Trình)
-6. Mirror tất cả sang `fe-user/`
-7. App.tsx routes `/budgets`, `/budgets/new`, `/budgets/:id` cả 2 app
-8. Menu resolver `Bg_*` ở Layout: `Bg_List` → `/budgets`, `Bg_Pending` → `/budgets?phase=Pending`, `Bg_Create` → `/budgets/new`
+**A. Hard blockers (chờ user / ops):**
+1. **UAT thật 1 tuần với 2-3 user** — Drafter (QS/NV.PB) + CCM + BOD ghi bug/friction
+2. **SMTP config** → bật Email outbox (BLOCKED chờ user cấp host/user/pass)
+3. **Rotate credentials** — admin + 30 demo + SA + vrapp + JWT secret
+4. **Schedule SQL backup daily** — `scripts/backup-sql.ps1` chưa schedule Task Scheduler

-**B. PE/Contract → Budget integration:**
-1. **PE form** thêm field `Ngân sách` select Budget (filter `Phase=DaDuyet && NamNganSach=current && ProjectId=peProjectId`). Lưu `PE.BudgetId`.
-2. **Contract form** tương tự — link sang Budget cho đối chiếu chi phí.
-3. PE Detail tab có thể thêm cột "So với ngân sách" — compute từ `BudgetDetail` tương ứng (match GroupCode + ItemCode) nếu có Budget link.
+**B. PE feature gap còn lại:**
+- **Export phiếu PDF/Excel** PE — pending (user nói không quan trọng lắm). Khi cần: tái dùng `IDocumentConverter` + template `PE-TrinhDuyet.docx`.

-**C. PE feature gap (carry over từ session 3):**
-1. **PE Workflow admin designer UI** `/system/pe-workflows/:typeCode` — mirror pattern `WorkflowsPage.tsx` + `WorkflowDesigner.tsx`. BE cần `PeWorkflowAdminFeatures.cs` + `PeWorkflowsController.cs`. Framework backend đã sẵn (3 bảng `PurchaseEvaluationWorkflow*` + `FromDefinition`), chỉ thiếu wire UI.
-2. **Ý kiến 4 phòng ban** (Phê duyệt / P.CCM / P.MuaHàng / SM-PM) — Excel form có, entity chưa map. Cần design: 4 text field + signoff date, hoặc dùng Approvals với role-kind.
-3. **Export phiếu PDF/Excel** — tái dùng `IDocumentConverter` + template `PE-TrinhDuyet.docx`.
-
-**D. Optional polish:**
- Budget MaNganSach atomic sequence (hiện Random.Shared, format chốt sau)
- Budget versioned workflow (admin config qua UI — hiện hardcoded `BudgetPolicy.Default`)
- Payment terms PE tách field
- Auto-map PE Details → Contract Details khi gen HĐ
+**C. Optional polish (làm khi UAT phát sinh):**
+- Budget MaNganSach atomic sequence — chốt format → migration `AddBudgetCodeSequences` mirror Contract/PE
+- Budget versioned workflow — admin config UI thay hardcoded `BudgetPolicy.Default`
+- Payment terms PE tách field — JSON blob → 6 column riêng
+- Auto-map PE Details → Contract per-type Details khi gen HĐ
 - Matrix Quotes bulk paste từ Excel

+| Layer | Framework | Note |
+|---|---|---|
+| .NET test | xUnit 2.9.3 | Industry standard |
+| Assertion | FluentAssertions 7.2 | Pin trước v8 commercial license |
+| EF testing | Microsoft.EntityFrameworkCore.Sqlite 10 | Phase 2+ — supports transactions |
+| Test fixture | Custom `SqliteDbFixture` + `TestApplicationDbContext` | Override `nvarchar(max) → TEXT` cho SQLite compat |
+
+**CI gate:** `.gitea/workflows/deploy.yml` chạy `dotnet test` cho từng test project TRƯỚC build/publish/deploy. Test fail → `exit $LASTEXITCODE` → no deploy.
+

+- name: Run unit tests (Domain)

+
+- name: Run integration tests (Infrastructure)
+  run: dotnet test tests/SolutionErp.Infrastructure.Tests/...
+```
+
+**Phase priority — anti-overkill:**
+
+1. **Phase 1 (Done)** — Domain policy: 3 test file (Contract WF / PE WF / Budget) cover transition rules + Registry + FromDefinition. ~54 test, < 7s.
+2. **Phase 2 (Done)** — Infra code generator: format RG-001/PE + sequence increment + year boundary (framework HĐ). ~17 test, ~2s.
+3. **Phase 3 (Pending)** — Application CQRS handler: critical state-change handlers (Transition + Create) với EF InMemory.
+4. **Phase 4 (Pending)** — API smoke: WebApplicationFactory + SQLite, 5-7 endpoint critical roundtrip.
+5. **Phase 5 (Pending)** — FE Vitest cho lib utility (queryMatches, fmtMoney) — chỉ pure functions, KHÔNG component snapshot.
+
+**Quy tắc bổ sung mỗi feature mới:**
+- Domain policy method → 2-3 test (positive + negative + edge)
+- CQRS handler có guard → 1 test mỗi guard branch
+- Bug found in production → 1 regression test added before merge

+Detail run: `dotnet test SolutionErp.slnx` chạy cả 71 test ~2s.

+
+**Migration:** 15 `AddPurchaseEvaluationDepartmentOpinions` — 1 bảng UNIQUE PEId+Kind cho 4 phòng ban sign-off.
+
+## A. FE Budget pages 3-panel (commit `df12fb1`)
+
+Mirror pattern PE 3-panel cho cả `fe-admin` + `fe-user`:
+
+| File | Mô tả |
+|---|---|
+| `types/budget.ts` | BudgetPhase 5-state enum + DTO types (BudgetListItem/DetailRow/Approval/Bundle/DetailBody) |
+| `pages/budgets/BudgetsListPage.tsx` | 3-panel `[340px_1fr_360px]` + filter Phase + Năm + `?phase=Pending` alias filter ChoCCM/ChoCEO + readOnly mode (menu Duyệt) + BudgetDetailPage fullpage mobile |
+| `pages/budgets/BudgetCreatePage.tsx` | Form Header (Tên/Năm/Dự án/Phòng ban/Mô tả). Edit mode khóa Project+Department |
+| `components/budgets/BudgetDetailTabs.tsx` | Section Thông tin Header + Section Hạng mục table CRUD inline (Add/Edit/Delete dialog auto-compute ThanhTien=KL×ĐG). Export `BudgetApprovalsSection` + `BudgetHistorySection` cho Panel 3 reuse |
+| `components/budgets/BudgetWorkflowPanel.tsx` | Panel 3 timeline activePhases visual + nextPhases buttons (Approve xanh / Reject đỏ / Trả về vàng) + Dialog xác nhận có comment + Approvals + Changelog |
+
+App.tsx 3 route mới `/budgets`, `/budgets/new`, `/budgets/:id` cả 2 app. Layout resolver `Bg_List`/`Bg_Create`/`Bg_Pending` + root `Budgets` icon Wallet.
+
+## B. PE/Contract → Budget integration (commit `61e5d4d`)
+
+### BE (6 file)
+
+- `Budgets/Dtos/BudgetDtos.cs`: + `BudgetSummaryDto` (compact header snapshot reuse cho PE & Contract)
+- `PE Dtos + Features`: + `BudgetId?` + `Budget?` vào DetailBundle. Create/Update PE commands + validate cùng Project + Phase=DaDuyet
+- `Contract Dtos + Features`: same pattern
+- `CreateContractFromEvaluation`: carry forward `pe.BudgetId → contract.BudgetId`
+
+### FE (10 file)
+
+- PE & Contract Create form: Select **"Ngân sách"** filter Phase=DaDuyet & Project match (BE-side filter qua `/budgets?projectId=&phase=4`)
+- PE InfoTab + Contract Edit: hiển thị Budget link clickable `→ /budgets?id=`
+- PE ItemsTab matrix: cột **"NS link · Δ"** chỉ hiện khi `ev.budgetId`, match per-row qua key `groupCode|itemCode` (fetch `/budgets/{id}` riêng), footer aggregate (xanh dưới / đỏ vượt / xám khớp)
+
+## C. PE Detail UI restructure (commit `7e36241`)
+
+Match form chính thức **PHIẾU TRÌNH KÝ CHỌN TP/NCC** với 4 section đánh số:
+
+```
+1. Thông tin gói thầu       (a Tên + b Dự án + Địa điểm/Mô tả compact)
+2. Chọn NCC / TP             (a NCC chọn / b Ngân sách / c Giá chào thầu auto-compute / d Bản so sánh)
+3. NCC / TP tham gia ({n})   (table 5 cột UX web)
+4. Hạng mục + Báo giá ({n})  (matrix + cột "NS link · Δ")
+5. Ý kiến 4 phòng ban (sign-off)  (2x2 grid OpinionBox — Section thêm trong commit kế)
+```
+
+**Section 2.c "Giá chào thầu"** auto-compute: lookup `winnerSupplierRowId` qua `selectedSupplierId`, sum quotes có `purchaseEvaluationSupplierId === winnerRowId`. Hiện "—" khi chưa chọn NCC hoặc chưa nhập báo giá.
+
+**Section 2.d "Bản so sánh"** dùng filter `purchaseEvaluationSupplierId === null` (file tổng, không gắn NCC cụ thể).
+
+`FormRow` helper mới (label 176px + value flex) thay cho dl grid 2-col cũ. Drop helper `Field` cũ.
+
+## D. PE Workflow Designer admin UI + Ý kiến 4 phòng ban (commit `5d94bb4`)
+
+### PE Workflow Designer
+
+- BE `Application/PurchaseEvaluations/PeWorkflowAdminFeatures.cs` ~250 LOC mirror Contract WorkflowAdminFeatures (GetOverview + CreateNewVersion deactivate cũ atomic)
+- BE `Api/Controllers/PeWorkflowsController.cs` 2 endpoint reuse policy `Workflows.Read` + `Workflows.Create`
+- FE `pages/system/PeWorkflowsPage.tsx` ~500 LOC: Landing 2-card grid → TypePanel khi pick code → DefinitionCard active+history + PeWorkflowDesigner dialog (clone từ existing + edit Code/Name/Description + add/remove steps + +Role / +User approvers)
+- App.tsx route `/system/pe-workflows` + `/system/pe-workflows/:typeCode`. Resolver `PeWf_<Code>` từ session 3 đã trỏ.
+
+### Ý kiến 4 phòng ban PE
+
+**Migration 15** `AddPurchaseEvaluationDepartmentOpinions`:
+
+```sql
+CREATE TABLE PurchaseEvaluationDepartmentOpinions (
+  Id, PurchaseEvaluationId FK Cascade,
+  Kind INT NOT NULL,    -- 1=PheDuyet, 2=Ccm, 3=MuaHang, 4=SmPm
+  Opinion NVARCHAR(2000) NULL,
+  SignedAt DATETIME2 NULL,
+  UserId UNIQUEIDENTIFIER NULL,
+  UserName NVARCHAR(200) NULL,
+  -- AuditableEntity columns
+);
+CREATE UNIQUE INDEX ON (PurchaseEvaluationId, Kind);  -- max 1 row mỗi loại phòng ban per phiếu
+```
+
+- Domain entity `PurchaseEvaluationDepartmentOpinion` + enum `PeDepartmentKind`
+- Application `PeDepartmentOpinionFeatures.cs`: Upsert pattern (sign=true → set SignedAt+UserId+UserName denorm, sign=false → giữ chữ ký cũ chỉ update text), Delete admin override
+- API `POST /api/purchase-evaluations/{id}/opinions` + `DELETE .../opinions/{kind}`
+- FE Section "5. Ý kiến 4 phòng ban (sign-off)" 2x2 grid `OpinionBox`:
+  - Read mode (menu Duyệt readOnly): hiển thị text + chữ ký
+  - Edit mode: textarea + 2 button "Lưu text" / "Lưu & Ký"
+  - Badge "Đã ký" emerald + tên người ký + ngày
+
+## E. Tests Phase 1 — Domain unit tests + CI gate (commit `d3f9346`)
+
+```
+tests/SolutionErp.Domain.Tests/
+├── Contracts/WorkflowPolicyTests.cs              (~17 test)
+├── PurchaseEvaluations/PurchaseEvaluationPolicyTests.cs (~17 test)
+├── Budgets/BudgetPolicyTests.cs                  (~13 test)
+└── SolutionErp.Domain.Tests.csproj               (xUnit 2.9.3 + FluentAssertions 7.2)
+```
+
+**Coverage:**
+- Standard 9-phase + SkipCcm 7-phase (HĐ): role transitions, CCM check, BOD signing, terminal phase, reject paths
+- Registry: DefaultPolicyName per ContractType (7 type) + bypass flag override Standard→SkipCcm
+- FromDefinition versioned: build từ ordered steps + reject path back to draft + TuChoi auto-add + UserKindApprover populate UserTransitions
+- NccOnly (PE-A) 3-step + NccWithPlan (PE-B) 5-step: skip ChoDuAn/ChoCEODuyetPA chỉ ở B
+- BudgetPolicy Default 3-step + DaDuyet/TuChoi terminal + SLA spec verify (5d/3d/2d)
+
+**CI gate** `.gitea/workflows/deploy.yml`:
+
+```yaml
+- name: Run unit tests (Domain)
+  run: dotnet test tests/SolutionErp.Domain.Tests/...
+  # Fail → exit $LASTEXITCODE → no deploy
+```
+
+54 test pass / 6.4s. Verify local: `dotnet test SolutionErp.slnx`.
+
+## F. Tests Phase 2 — Code generator format + sequence (commit `df5988b`)
+
+```
+tests/SolutionErp.Infrastructure.Tests/
+├── Common/SqliteDbFixture.cs                     (Test fixture + TestApplicationDbContext)
+├── Services/ContractCodeGeneratorTests.cs        (~10 test)
+├── Services/PurchaseEvaluationCodeGeneratorTests.cs (~7 test)
+└── SolutionErp.Infrastructure.Tests.csproj       (+ EF Sqlite 10)
+```
+
+### Setup SQLite in-memory
+
+- `TestApplicationDbContext` subclass override `OnModelCreating` — iterate model, replace bất kỳ column type chứa "max" → "TEXT" (SQLite không support `nvarchar(max)`)
+- `FixedDateTime` stub `IDateTime` (control year boundary deterministic)
+- Shared `SqliteConnection` open trong fixture, EnsureCreated() từ DbContext model
+
+### Coverage
+
+- Format RG-001 cho 5 ContractType (HĐTP/HĐGK/NCC/HĐDV/MB) — `{Project}/{TypeCode}/SOL&{Supplier}/{Seq}`
+- Framework HĐ (NguyenTacNCC + NguyenTacDV) đặc biệt — `{Year}/{TypeCode}/SOL&{Supplier}/{Seq}` (year scope thay vì project)
+- Sequence increment per prefix (`/01` → `/02` → `/03`)
+- Different prefixes (project / supplier khác) có sequence độc lập
+- Year boundary cho framework — sang 2027 prefix mới reset seq
+- PE format `PE/{YYYY}/{A|B}/{Seq:D3}` — 3-digit padding test với 12 phiếu
+- PE Type A và B sequence độc lập trong cùng năm
+- PersistsSequenceRow LastSeq + UpdatedAt verification
+
+**CI gate** thêm step thứ 2 — fail-fast tương tự Domain.
+
+17 test pass / 2s. Total session 5 test count = **71** (54 Domain + 17 Infra).
+
+## G. Stats sau session 5
+
+| | Trước S5 | Sau S5 |
+|---|---:|---:|
+| BE LOC | ~11750 | **~13050** (+1300 PE WF Designer + Opinion + Budget integration) |
+| DB tables | 51 | **52** (+1 PEDeptOpinions) |
+| API endpoints | ~124 | **~128** (+2 PE WF + 2 Opinion) |
+| Migrations | 14 | **15** |
+| FE pages | ~26 | **~31** (+5 Budget + 1 PeWorkflowsPage) |
+| **Tests** | 0 | **71** (54 Domain + 17 Infra) |
+| CI gate | 1 (build) | **2 step test gate + build** |
+| Commits | ~75 | **~82** (+6 session 5 + chốt MD) |
+
+## H. Cảnh báo session 6
+
+1. **CI test gate active** — mỗi commit push trigger 2 step `dotnet test`. Test fail → NO deploy. Workflow mới: code → `dotnet test SolutionErp.slnx` local → commit → push.
+2. **Chưa xóa binding cũ `.huypham.vn`** — fallback active. Sau verify stable: `.\migrate-domains.ps1 -RemoveOld -SkipCert`.
+3. **win-acme scheduled task "unhealthy"** — fix trước cert expire 2026-06-18.
+4. **Login email default** vẫn `admin@solutionerp.local` (chỉ rebrand demo user).
+5. **Atomic sequence Budget chưa chốt** — Random.Shared race risk thấp nhưng không zero.
+6. **Versioned workflow Budget chưa có** — hardcoded `BudgetPolicy.Default` 3-step.
+7. **Export phiếu PDF/Excel PE** pending vô thời hạn (user nói không quan trọng lắm).
+
+## I. Lessons learned session 5
+
+1. **Test pyramid bottom-heavy hợp solo dev** — 71 test (54 Domain pure + 17 Infra SQLite) chạy < 3s. Bỏ E2E, tránh maintenance overhead.
+
+2. **SQLite in-memory cho code generator test** đủ test format + sequence + year boundary, KHÔNG đủ test race condition thực (cần SQL Server thật cho `IsolationLevel.Serializable` strict). Workaround tốt cho CI runner không có LocalDB.
+
+3. **TestApplicationDbContext subclass override** — pattern sạch nhất để adapt SQL Server-specific model (`nvarchar(max)`) cho SQLite mà không touch production DbContext.
+
+4. **CI gate ROI cao cho solo dev** — bug Domain logic recurring (workflow phase, role transition) sẽ block deploy ngay. ~3.5 ngày upfront cho 5 phase, có thể stop ở Phase 2 (1.5 ngày) nếu Phase 3-5 ROI chưa rõ.
+
+5. **PE Detail UI restructure theo spec form giấy** — match 4 section đánh số PHIẾU TRÌNH KÝ giúp UX consistent giữa fill web và print PDF (tương lai).
+
+6. **Sign-off 4 phòng ban dùng table riêng thay vì 12 column header** — UNIQUE(PEId, Kind) bảo vệ max 1 row mỗi phòng, dễ query "phòng nào chưa ký", dễ extend nếu thêm kind.
+
+7. **Workflow user mới end-of-task** = `dotnet test SolutionErp.slnx` → commit → push. CI tự run test gate trước build/deploy.
