HANDOFF — Brief 5 phút cho session tiếp theo

Last updated: 2026-04-22 03:00 (post-Tier-3-feature-complete + versioned workflow)

TL;DR

Tier 3 ERP features xong hết (Attachment, SignalR, Form builder, PDF, Versioned workflow, Nested menu, Permission layout). Prod live 3 domain. Còn lại chủ yếu là UAT + SMTP + rotate creds, không còn module kỹ thuật lớn nào chưa làm.

Ở đâu rồi?

Phase	Trạng thái
0 Draft	✅ Done
1 Alpha Core (foundation + đợt 2 CRUD + Permission)	✅ Done
2 Form Engine MVP + iter 2 (upload UI + .doc auto-convert + PDF export)	✅ Done
3 Workflow MVP (9 phase + code gen) + iter 2 (SLA job + attachment + notify)	✅ Done
4 Report MVP (Dashboard + Excel) + user-specific dashboard	✅ Done
5 Prep + 5.1 Security + Users Mgmt	✅ Done
5 Deploy prod (3 domain HTTPS live)	✅ Done
Tier 3 (Attach + Realtime + Form builder + PDF + Versioned WF + Nested menu + Permission 3-panel)	✅ Done
6+ Post-launch (E-signature, Bravo/SAP, Mobile, AI)	📝 Future

Run nhanh

# Terminal 1 — API (auto seed 12 role + 9 dept + 5 supplier + 3 project + 8 template + 7 workflow definition + 28 ContractType menu + 7 workflow menu)
dotnet run --project src\Backend\SolutionErp.Api

# Terminal 2 — Admin FE
cd fe-admin && npm run dev  # → http://localhost:8082

# Terminal 3 — User FE
cd fe-user && npm run dev   # → http://localhost:8080

Login: admin@solutionerp.local / Admin@123456

Quick sanity-check

Admin (:8082):

• /dashboard → "Của tôi" row 4 card + KPI cards + charts
• /contracts → list toàn bộ, filter phase/supplier/project
• /contracts/new?type=5 → tạo HĐ Mua bán, pre-select type từ URL
• /contracts/{id} → timeline + action dialog + attachments drag-drop + WorkflowSummaryCard
• /system/workflows → 7-card landing (Thầu phụ/Giao khoán/NCC/Dịch vụ/Mua bán/NguyenTacNcc/NguyenTacDv)
• /system/workflows/MuaBan → DefinitionCard active + history + "Tạo phiên bản mới" modal với Steps + Approvers (+Role / +User)
• /system/permissions → 3-panel layout (Role list | Menu×CRUD matrix | Granted stats)
• /system/users → Users CRUD + assign roles
• /forms → upload .docx/.xlsx + render dialog Form↔JSON + Tải PDF

User (:8080):

• /inbox?type=5 → HĐ Mua bán chờ role mình
• /my-contracts?type=2 → HĐ Thầu phụ của tôi
• /contracts/new?type=3 → tạo HĐ NCC
• Sidebar nested: 📄 Hợp đồng → expand 7 type → expand "HĐ Mua bán" → Danh sách / Thao tác / Duyệt

Realtime check:

• Login 2 tab (admin + user) → user tạo comment / transition → admin nhận toast + bell +1

Cần làm kế tiếp

A. Hard blockers (chờ user / ops)

1. UAT thật 1 tuần với 2-3 user — hard requirement từ roadmap. Kiến nghị:
   • User A: Drafter (QS/NV.PB) — tạo 3 HĐ mỗi type, đi hết 9 phase
   • User B: CCM — duyệt phase 6
   • User C: BOD — duyệt phase 7
   • Ghi bug / friction / đề xuất → backlog iter 2
2. SMTP config để bật Email outbox:

   "Email": {
     "Host": "smtp.gmail.com",
     "Port": 587,
     "Username": "...",
     "Password": "...",
     "From": "noreply@solutionerp.local"
   }
   

   Khi có → thêm MailKit, IEmailSender, hook vào NotificationService.CreateAsync ngay trước khi enqueue realtime push.
3. Rotate credentials — SA SQL password, vrapp password, JWT secret prod, Gitea runner registration token
4. Schedule SQL backup — schtasks /create /tn "SolutionErp Backup" /tr "powershell -File C:\...\scripts\backup-sql.ps1" /sc DAILY /st 03:00

A1. Định kỳ — Skill audit

Cadence: Mỗi đầu tháng (4 tuần). Lần audit kế tiếp: 2026-05-01.

Workflow xem docs/rules.md §9.4. Tóm tắt:

1. Cross-check 6 skill hiện có với STATUS / gotchas / migration-todos
2. Check repo nguồn 3rd party (alirezarezvani/claude-skills) có gì mới
3. Update / archive / add skill nếu cần
4. Log vào docs/changelog/skill-audit-2026-05.md

Trigger: user nói "audit skill" hoặc tự chạy đầu Phase mới.

B. Polish iterations (optional — khi UAT phát sinh)

• Roles CRUD — admin tạo custom role ngoài 12 hardcoded (Domain.Identity.AppRoles)
• User-kind approver runtime — data model WorkflowStepApprover.Kind=User + AssignmentValue=userId đã có, chỉ cần:

  // ContractWorkflowService.TransitionAsync (bổ sung):
  var userApprovers = step.Approvers.Where(a => a.Kind == ApproverKind.User)
                                    .Select(a => Guid.Parse(a.AssignmentValue));
  if (userApprovers.Any() && !userApprovers.Contains(actorUserId))
      throw new ForbiddenException();
  

• Grant Workflows.Read cho non-admin role trong PermissionsPage → menu Wf_* auto-visible (inheritance đã có)
• Warning notification 20% SLA — job emit khi SlaDeadline - now < sla * 0.2 && !SlaWarningSent, set flag
• Reject → DangSoanThao E2E test với 3 role khác nhau
• Deps scan CI — dotnet list package --vulnerable + npm audit --audit-level=high

C. Non-goals / parked

• E-signature (VNPT CA / FPT CA) — Phase 6
• Bravo/SAP import NCC — Phase 6
• Mobile app — Phase 6
• AI OCR scan HĐ — Phase 6+

Lưu ý kỹ thuật quan trọng

Đọc gotchas.md (26 bẫy) trước khi:

• Thêm package mới → .NET 10 compat (MediatR 14 fail → dùng 12.4.1)
• Debug TS enum error → dùng const-object pattern (erasableSyntaxOnly)
• Expression tree lỗi → tách switch ra ngoài LINQ
• Deploy Windows Feature (WebSockets, etc.) → unlock section ở applicationHost (gotcha #25)
• Workflow transition 403 → check Contract.WorkflowDefinitionId pin đúng không
• Migration lỗi → 3 file đầy đủ (Designer + Migration + Snapshot)

Versioned workflow — quick reference

Contract.WorkflowDefinitionId (nullable Guid FK)
  → pin tại `CreateContractCommandHandler` = WorkflowDefinitions.Single(d => d.ContractType == c.Type && d.IsActive)
  → ContractWorkflowService.LoadAsync(contractId):
      if contract.WorkflowDefinitionId != null:
        def = db.WorkflowDefinitions.Include(Steps.Approvers).First(wfId)
        return WorkflowPolicyRegistry.FromDefinition(def)
      else if admin override ở WorkflowTypeAssignments:
        return Registry.ByName(override.PolicyName)
      else:
        return Registry.For(contract.Type)  // hardcoded Standard/SkipCcm

Admin tạo version mới:
  POST /api/workflows
    body: { code, name, contractType, steps: [{ order, phase, name, slaDays, approvers: [{ kind, assignmentValue }] }] }
  → auto increment Version = max(Version where Code==code) + 1
  → deactivate old IsActive trong cùng ContractType (atomic)
  → HĐ cũ ĐÃ PIN WorkflowDefinitionId = old Id → vẫn chạy policy cũ ✓

Invariants:

• UNIQUE (Code, Version) per WorkflowDefinitions
• Chỉ 1 IsActive=true per ContractType tại 1 thời điểm
• Contract.WorkflowDefinitionId KHÔNG cascade khi xóa WorkflowDefinition → protect history

Đánh giá nhanh

Tốt:

• 3 domain HTTPS prod live, CI/CD xanh
• Tier 3 feature-complete: attachment, realtime, form builder (upload + DynamicForm + PDF), versioned workflow (admin-configurable per ContractType, pin per contract), nested menu per type, 3-panel permissions
• Clean-arch 3-project split đúng cho 2 cross-cutting service (realtime + document-converter)
• 26 gotchas tích lũy, 8 session log, 40 docs — agent onboard nhanh
• Invariant critical: "HĐ cũ giữ quy trình cũ" guaranteed by pinning (reference-based immutability, không snapshot copy)

Rủi ro còn:

• UAT thật chưa chạy → có thể phát hiện edge case missing
• SMTP chưa có → notification chỉ in-app (toast + bell), không email
• User-kind approver chưa enable guard runtime (designer cho pick, nhưng transition dùng Role fall-back)
• Credentials chưa rotate
• SQL backup chưa schedule Task Scheduler
