SOLUTION_ERP — Hệ thống Quản lý Hợp đồng Nhà cung cấp / Thầu phụ / Tổ đội + Phiếu Duyệt NCC tiền-HĐ cho Công ty TNHH Xây dựng Solutions.

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

🚀 BẮT ĐẦU SESSION — 5 file đọc trước tiên

1. docs/STATUS.md                        ← Snapshot HIỆN TẠI (phase nào, việc gì đang làm — PE module CÒN CHỈNH NHIỀU)
2. docs/HANDOFF.md                       ← Brief 5 phút: session trước làm gì + cảnh báo session tiếp
3. docs/PROJECT-MAP.md                   ← Bản đồ toàn cảnh
4. docs/changelog/migration-todos.md     ← Atomic tasks theo phase (Phase 7 PE refinement mới)
5. docs/workflow-contract.md             ← ⭐ State machine 9 phase HĐ — base pattern cho PE workflow

⚡ 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, PurchaseEvaluations, ...)
• 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
• Hiện có 43 migration → 91 bảng (Phase 10 COMPLETE + Phase 11 P11-A/B — Mig 34-42 HRM/Office/WorkflowApps/Attendance + Contract V2 (32-33) + WireWorkflowApps V2 (41) + LeaveBalance (42) + Holiday filtered-unique (43, S45). V2 schema history S29-era bên dưới giữ nguyên — Mig 32+33 Plan B Contract V2 cookie-cutter mirror PE Mig 22-26 (S29). Mig 26 AddPeLevelOpinionsForV2: bảng mới PurchaseEvaluationLevelOpinions UNIQUE composite (PEId, LevelId), FK Cascade Pe + Restrict Level. Section 5 "Ý kiến cấp duyệt" V2 dynamic theo workflow đã pin: forEach Step (Phòng) → forEach Level (Cấp) → forEach NV → 1 OpinionBox. Service ApproveV2Async UPSERT auto khi NV duyệt — Q1=1B (sync gắn với Duyệt, KHÔNG form input rời). SignedByUserId track signer thật, FE banner "Admin duyệt thay" khi !== ApproverUserId. Comment empty → "(duyệt — không ý kiến)" placeholder. Phiếu V1 legacy fallback Mig 15 4 box readOnly (data history). Mig 25 AddIsUserSelectableToApprovalWorkflows: ALTER ApprovalWorkflows +IsUserSelectable bit (admin pin/unpin workflow nào cho user pick lúc create phiếu, multi-select độc lập IsActive). Backfill WHERE IsActive=1 SET 1 giữ behavior cũ. Designer +badge "Cho user chọn" + button Ghim/Bỏ ghim. Workspace filter dropdown chỉ workflows IsUserSelectable=true. Mig 22-24 V2 schema (Session 17): ApprovalWorkflows/Steps/Levels — Quy trình > Bước (Phòng) > Cấp (N NV cụ thể qua ApproverUserId, OR-of-N cùng cấp). PE.ApprovalWorkflowId pin V2. PE.CurrentApprovalLevelOrder track. State machine 5 trạng thái: Nháp / Đã gửi duyệt / Trả lại (Phase riêng TraLai=98) / Từ chối / Đã duyệt. PE Service V2 wire match actor.Id == ApproverUserId. Contract V2 ĐÃ WIRE (Mig 32+33 Plan B S29 — cookie-cutter mirror PE V2: ApproveV2Async + ContractLevelOpinions UPSERT + Workspace V2 Select dropdown). Mig 21 V1 flat workflow vẫn live cho phiếu cũ.)

Modules

Module	Namespace	Migration	Trạng thái
Contract (HĐ)	Domain/Contracts/	1-11	Feature-complete (7 ContractType × 9 phase)
PurchaseEvaluation (Duyệt NCC tiền-HĐ)	Domain/PurchaseEvaluations/	12, 13, 15	Feature-complete — chỉ Export PDF còn pending (không quan trọng)
Budget (Ngân sách dự án)	Domain/Budgets/	14	Feature-complete — BE + FE 3-panel + integration với PE/HD
Master (Supplier/Project/Department)	Domain/Master/	2, 10	Feature-complete
Identity (User/Role/Permission/MenuItem)	Domain/Identity/	1, 3, 11	Feature-complete (30 demo user — 16 sample + 14 Solutions thật)
Forms (Template + Clause)	Domain/Forms/	4	Feature-complete
Notifications	Domain/Notifications/	6	In-app + SignalR OK, email SMTP TODO
Tests	tests/SolutionErp.{Domain,Infrastructure}.Tests/	—	181 test pass (58 Domain + 123 Infra) — CI gate + path filter docs-only skip

🧪 Tests (Phase 9 — Session 9 +6)

tests/
├── SolutionErp.Domain.Tests/         (58 test — Domain policy: Workflow / PE / Budget)
└── SolutionErp.Infrastructure.Tests/ (123 test)
    ├── Common/                       (SqliteDbFixture + TestApplicationDbContext + IdentityFixture S9)

    └── Application/                  (6 test - PeWorkflowDefinition versioning)

181 unit test pass (58 Domain + 123 Infra). CI gate + path filter live. (S45: 3 coverage gap S35-S38 ĐÓNG +27 test + Mig 43 Holiday filtered-unique fix. Backlog gotcha #57: LeaveType/Shift Code unfiltered.)

dotnet test SolutionErp.slnx     # chạy cả 2 test project

Quy tắc timing test: feature mới = test-after (UAT ổn → viết). Bug fix = test-before BẮT BUỘC (reproduce → fix). Critical algorithm (codegen/guard/financial/security) = test-before merge. Spec change = update test cũ + code chung commit. Skip: DTO mapping, CRUD master, FE snapshot. Detail docs/rules.md §7.

CI/CD pipeline (3 fix lớn 29/04)

• ✅ Manual checkout bypass github.com (fix gotcha #39 TCP timeout)
• ✅ Path filter docs-only skip — paths-ignore (gotcha #41)
• ⏸️ npm cache (gotcha #40 — failed, rolled back)

Tốc độ: code commit ~3 phút / docs-only commit 0s (skip).

🛠️ Skills (.claude/skills/) — 6 skill PHẢI dùng khi task khớp

Domain (3)	Ops (3)
contract-workflow — state machine + versioned WF	dependency-audit-erp — npm/dotnet CVE scan
form-engine — render docx/xlsx + PDF	ef-core-migration — EF migration + 3-file rule
permission-matrix — role × menu × CRUD	iis-deploy-runbook — 3 site IIS + win-acme + runner

Audit định kỳ: đầu mỗi tháng — combined skill + doc drift audit theo docs/rules.md §6.4 + §9.4. Cron solution-erp-skill-audit-monthly fire 9:00 ngày 1. Lần kế: 2026-07-01 (S44 đã chạy 06-01).

Quy tắc:

• KHÔNG bulk-clone repo skill 3rd party. Chỉ thêm skill PROJECT-SPECIFIC. Xem docs/rules.md §9 đầy đủ.
• KHÔNG rewrite toàn bộ MD định kỳ. Chỉ compact + patch drift. Xem docs/rules.md §6.4 đầy đủ.

⚠️ Kết thúc session

1. Update docs/STATUS.md (In Progress → Recently Done)
2. Tick checklist tương ứng trong docs/changelog/migration-todos.md
