pqhuy1987 fe7ad8e4a3 [CLAUDE] Phase4: Report MVP + Docs Consolidation (rules, architecture, schema-diagram) 
Backend Report:
- Application/Reports/Dtos/DashboardStatsDto: 5 KPI + PhaseCount + SupplierCount + ProjectCount + MonthlyValue
- Application/Reports/Queries/GetDashboardStats handler: total/active/overdue/published this month/totalValueActive + byPhase + top 5 NCC/du an + 12 thang monthly (fill zero khi thang empty)
- Application/Reports/Services/IContractExcelExporter interface
- Infrastructure/Reports/ContractExcelExporter: ClosedXML workbook 10 cot, header style bold+blue, number format #,##0, formula SUM, auto-fit, freeze header
- Application/Reports/Commands/ExportContractsToExcelCommand: filter phase/supplier/project/date range
- Api/Controllers/ReportsController: GET /reports/dashboard, GET /reports/contracts/export
- DI register IContractExcelExporter (Scoped)

Frontend fe-admin:
- types/reports.ts: DashboardStats type
- components/BarChart.tsx: generic horizontal bar chart — chi Tailwind, khong thu vien ngoai
- pages/DashboardPage.tsx REWRITE: 5 KPI card (FileText/TrendingUp/AlertTriangle/CheckCircle2/Coins) + by-phase bar + monthly 12-month chart + top 5 NCC + top 5 du an + skeleton loader
- pages/ReportsPage.tsx MOI: filter phase/fromDate/toDate → export Excel button
- Route /reports vao App.tsx

E2E verified:
- GET /api/reports/dashboard → 200 voi day du KPI + monthly fill 12 thang
- GET /api/reports/contracts/export → 200 xlsx 7229 bytes (Microsoft Excel 2007+)

Docs consolidation (theo yeu cau user):
- docs/rules.md MOI: 9 section coding conventions (ngon ngu UI/code/DB/docs, BE Clean Arch, CQRS+MediatR, Validation FluentValidation, Error handling, Async, Entity rules, DI, Package pinning, FE React/TS erasableSyntaxOnly, path alias, TanStack Query, Permission guard, Toast+error, DB convention, Git commit format, Docs structure, Testing, Security)
- docs/architecture.md MOI: layered overview ASCII art, request lifecycle (1 POST/api/contracts qua 10 step), workflow state machine 9 phase, permission model, data flow sequence diagram 4 actor (Drafter/Manager/CCM/BOD/HRA), deployment architecture Phase 5, skill library, non-functional table
- docs/database/schema-diagram.md MOI: full ERD 19 table mermaid + data flow diagram + vong doi 1 HD (create → 7 transition → gen ma → publish) + index strategy table + relationship cardinality + soft delete behavior + SQL queries (inbox/dashboard/gen ma) + migration history
- docs/gotchas.md UPDATE: 17 → 26 pitfalls, them section "Claude Code harness quirks" (Edit File not read, DI build pass nhung runtime fail) + "Contract workflow" (ma HD gen 2 lan, BE-FE NEXT_PHASES sync, race condition) + "Permission matrix" (cache real-time, MenuKey typo)
- docs/STATUS.md: Phase 4 MVP done, docs entry points section liet ke het, next Phase 5 Production
- docs/HANDOFF.md: phase table them Phase 4 row, file tree update voi Reports, test points day du, git state commit 7
- docs/changelog/migration-todos.md: tick Phase 4 MVP items + them iteration 2 list
- docs/changelog/sessions/2026-04-21-1430-phase4-report.md: session log voi thong so cumulative (BE 3100 LOC, 30 docs)
- CLAUDE.md root: update Tai lieu quan trong section them rules.md, architecture.md, schema-diagram.md, .claude/skills (13 links now)

Bug fix:
- TS unused import ContractPhaseLabel trong DashboardPage
- DI thieu register IContractExcelExporter — build pass but runtime would fail (added)

CLAUDE.md — AI Agent Context

Full content: docs/CLAUDE.md

SOLUTION_ERP — Hệ thống Quản lý Hợp đồng Nhà cung cấp / Thầu phụ / Tổ đội cho Công ty TNHH Xây dựng Solutions.

Kiến trúc: .NET 10 Clean Architecture + 2 React FE (admin + user) + SQL Server + IIS.

🚀 BẮT ĐẦU SESSION — 4 file đọc trước tiên

1. docs/STATUS.md                        ← Snapshot HIỆN TẠI (phase nào, việc gì đang làm)
2. docs/PROJECT-MAP.md                   ← Bản đồ toàn cảnh (nên đọc đầu dự án)
3. docs/changelog/migration-todos.md     ← Atomic tasks theo từng phase
4. docs/workflow-contract.md             ← ⭐ State machine 9 phase — ảnh hưởng mọi thiết kế

⚡ Quick Rules

Backend — .NET 10 Clean Architecture

  • Solution: SolutionErp.slnx ở root, projects ở src/Backend/
  • 4 layer: Api → Application ← Domain + Infrastructure → Application
  • Pattern: CQRS + MediatR, FluentValidation, AutoMapper
  • Repository qua IApplicationDbContext interface (Application layer)
  • Auth: JWT Bearer + ASP.NET Identity
  • DB: SQL Server (LocalDB dev / SQL Server prod), EF Core 10 Code-First migrations
  • Error handling: GlobalExceptionMiddleware map exception → HTTP status
  • Commit scope tech stack: Api · App · Domain · Infra

Frontend — 2 app React 18 + Vite + TS + shadcn/ui + TanStack Query

  • fe-admin/ (port 8082) · fe-user/ (port 8080)
  • Vite proxy /api → http://localhost:5443 (SolutionErp.Api)
  • Named export, không default export (trừ App)
  • shadcn/ui copy-paste, duplicate giữa 2 app là CÓ CHỦ ĐÍCH (mỗi app UX riêng)
  • Auth context: solution-erp-admin-token / solution-erp-user-token ở localStorage
  • TanStack Query cho data fetching
  • Node pin >=20 trong engines; CI pin 20.x qua .nvmrc (bài học NamGroup — KHÔNG dùng Node latest trên CI)
  • UI 100% tiếng Việt

Database conventions

  • Schema: dbo (single schema)
  • Table: PascalCase tiếng Anh (Contracts, Suppliers, Projects, ContractApprovals, ...)
  • PK: Id (Guid), FK: {Entity}Id
  • Audit fields: CreatedAt, UpdatedAt, CreatedBy, UpdatedBy (BaseEntity)
  • Soft delete: IsDeleted, DeletedAt, DeletedBy (AuditableEntity)
  • Migrations: dotnet ef migrations add <Name> --project src/Backend/SolutionErp.Infrastructure --startup-project src/Backend/SolutionErp.Api

Commit convention

[CLAUDE] <scope>: <imperative message>

Scope: Contract · Form · Workflow · Supplier · Auth · Admin · Api · App · Domain · Infra · FE-Admin · FE-User · Docs · CICD · Scripts

⚠️ Kết thúc session

  1. Update docs/STATUS.md (In Progress → Recently Done)
  2. Tick checklist tương ứng trong docs/changelog/migration-todos.md
  3. Tạo session log docs/changelog/sessions/YYYY-MM-DD-HHMM-{topic}.md nếu đáng ghi
  4. Commit [CLAUDE] <scope>: <message>
  5. ⚠️ Update SolutionErp.slnx nếu có .cs/.csproj mới

Bỏ qua nếu chỉ trả lời câu hỏi, không sửa file nào.
