### Exit criteria Phase 1

- [ ] Admin login → tạo NCC/Project → tạo role "Nhân viên CCM" → gán permission menu "Contracts.Read"
- [ ] User CCM login → thấy menu Contracts, không thấy menu Admin
- [ ] Tạo Contract draft → list hiển thị, không bị 403 sai

- [x] FE admin: `FormsPage` — list + render dialog điền JSON + download
- [x] E2E verified: render FO-002.05 → file .docx 482KB mở được bằng Word

### Iteration 2 (optional — enhance)

- [ ] Convert 3 file `.doc` → `.docx` (retry Word COM với `DisplayAlerts=0` + timeout, hoặc LibreOffice headless)

- [ ] Support `{{#loop}}...{{/loop}}` block cho table lặp (hạng mục HĐ giao khoán, PO)
- [ ] FE user: form builder dynamic — render từ fieldSpec thay vì điền JSON tay
- [ ] FE admin: upload template mới qua UI (POST multipart) + edit field mapping
- [ ] Lưu `ContractClause` (FO-002.04) dạng rich text, admin edit qua TipTap/TinyMCE
- [ ] PDF convert via LibreOffice headless (`soffice --headless --convert-to pdf`)
- [ ] Import/export template (backup/restore)

- [x] `Infrastructure/Services/ContractWorkflowService` — adjacency 9 phase + role guard + Admin bypass + system actor + bypass CCM (Chủ đầu tư)
- [x] `Infrastructure/Services/ContractCodeGenerator` — 7 format RG-001 + transaction SERIALIZABLE
- [x] CQRS: Create/UpdateDraft/Transition/AddComment/List/Inbox/GetDetail/Delete (8 feature)
- [x] `Api/Controllers/ContractsController` — 8 endpoint REST
- [x] FE admin: ContractsListPage + ContractDetailPage (timeline + action dialog)
- [x] FE user: InboxPage + ContractCreatePage + ContractDetailPage + MyContractsPage
- [x] PhaseBadge component + color map

- [ ] E2E test với non-admin user (Drafter/CCM/BOD role)
- [ ] Filter Inbox theo phase ở FE
- [ ] E2E test: reject → quay về DangSoanThao
- [ ] E2E test: SLA expired → auto-approve + log

## Phase 4 — Reporting + Polish (T10-11)

### MVP xong (iteration 1)

- [x] Dashboard admin: 5 KPI (total/active/overdue/published this month/total value) + by phase + top 5 NCC + top 5 dự án + 12 tháng
- [x] Excel export HĐ theo filter (phase/supplier/project/date range) qua ClosedXML
- [x] BE `GetDashboardStatsQuery` + `ExportContractsToExcelCommand` + ReportsController

- [ ] Pin Node 20.x trong workflow, test CI sớm (không để surprise cuối dự án)
- [ ] `scripts/deploy-iis.ps1` — stop app pool, xcopy, start app pool
- [ ] Windows Server setup: IIS + URL Rewrite + ARR (reverse proxy FE → IIS)
- [ ] SQL Server prod: backup plan daily + weekly full
- [ ] HTTPS certificate (Let's Encrypt qua win-acme hoặc mua cert)
- [ ] `appsettings.Production.json` + user secrets
- [ ] Security audit: owasp top 10 check
- [ ] Rate limiting middleware (AspNetCoreRateLimit hoặc built-in)
