pqhuy1987 7710d4345c [CLAUDE] Docs+Skill: Session 19 consolidate — schema-diagram §15 + skill refresh
User chốt Session 19 toàn bộ: update các MD chưa làm ở Chunk D Docs
trước (theo §6.5 không cố sửa khi không cần — nhưng schema mới fundamental
+ skill drift quá lệch → đáng update ngay).

- docs/database/schema-diagram.md — thêm §15 PE Level Opinions V2 (Mig 26):
  bối cảnh decision (5 câu Q&A user chốt), schema bảng + constraint design
  rationale (UNIQUE composite, FK Cascade Pe + Restrict Level, denorm
  SignedByFullName), Service hook pattern (ApproveV2Async UPSERT), so sánh
  anti-pattern Mig 15 cũ (endpoint POST/opinions rời) vs Mig 26 (Service
  hook auto sync khi Duyệt). Pattern reusable cho derived state khác.
  §16 cũ "Liên quan" đổi thành §16 (renumber).
- .claude/skills/ef-core-migration/SKILL.md — frontmatter "21 migration"
  → "26 migration" + table history thêm Mig 22 ApprovalWorkflowsV2 / Mig
  23 PE.ApprovalWorkflowId / Mig 24 CurrentApprovalLevelOrder / Mig 25
  IsUserSelectable / Mig 26 PeLevelOpinionsForV2. Total bảng 55→59. Code
  pointers + Related cross-ref §15 mới.
- .claude/skills/README.md — count "16 migration" → "26 migration" + "41
  bẫy" → "44 bẫy" (drift cumulative S16-S19 patch).

Path filter `.claude/skills/**` + `docs/**` → CI skip deploy (gotcha #41).

Verify: dotnet test 81 pass (no regression).

Memory home dir KHÔNG commit (ở C:\Users\pqhuy\.claude\): add entry mới
`feedback_service_hook_vs_endpoint.md` + MEMORY.md index +1 row (15
entries total).

# Skill Library — SOLUTION_ERP
Skill này là tài liệu chuyên biệt để Claude (và developer khác) dùng khi cần deep-dive 1 domain area. Claude tự động invoke qua Skill tool dựa trên semantic matching với `description` trong từng `SKILL.md`.
## Skills hiện có
### Domain skills (logic nghiệp vụ)
| Skill | Mục đích | Trigger ví dụ | Trạng thái |
|---|---|---|---|
| `contract-workflow` | State machine 9 phase + versioned workflow per ContractType + role × phase guard + SLA + auto-gen mã HĐ RG-001 | "approve contract", "chuyển phase", "versioned workflow", "HĐ cũ giữ cũ" | ✅ Tier 3 + Phase 6 cross-ref PE workflow |
| `form-engine` | Render template docx/xlsx + FieldSpec JSON + DynamicForm + PDF export LibreOffice | "export contract as word", "điền form", "render template", "PDF export" | ✅ Active |
| `permission-matrix` | Role × MenuKey × CRUD + seed + 3-layer resolution + inherit Contracts/Workflows/PurchaseEvaluations | "permission denied", "gán role", "menu không hiện", "inherit permission" | ✅ Active (Phase 6 +Pe_*/PeWf_*) |
### Ops/infra skills (devops + security + schema)
| Skill | Mục đích | Trigger ví dụ | Trạng thái |
|---|---|---|---|
| `dependency-audit-erp` | Scan CVE NuGet + npm 2 FE, respect pin constraint (MediatR 12.4.1, Swashbuckle 6.9.0) | "npm audit", "dotnet vulnerable", "deps scan", "nâng cấp package" | ✅ New Tier 3 |
| `ef-core-migration` | Tạo/revert EF Core 10 migration, 3-file rule, DesignTimeDbContextFactory, **26 migration history** (Init → AddPeLevelOpinionsForV2) | "thêm migration", "EF migration", "schema update", "snapshot lỗi" | ✅ Updated Session 19 (Mig 26 PE Level Opinions V2) |
| `iis-deploy-runbook` | 3 IIS site + win-acme cert + gitea-runner + LibreOffice + debug 500/502/SignalR prod + **G-084 IPv4/IPv6 hardening** | "prod 500", "IIS fail", "cert hết hạn", "restart app pool", "deploy IIS", "port hijack" | ✅ Updated (G-084) |
## Format chuẩn 1 skill
Mỗi skill là 1 folder với ít nhất `SKILL.md` + optional `examples/` + `references/`:
```
.claude/skills/<skill-name>/
├── SKILL.md ← Entry point: description, when-to-use, workflow
├── examples/ ← Code snippets mẫu (optional)
│ └── *.cs | *.tsx
└── references/ ← Link đến file code thật, docs (optional)
```
**Frontmatter `SKILL.md` (BẮT BUỘC `when-to-use` để skill auto-trigger):**
```markdown
---
name: skill-name-kebab-case
description: 1-3 câu mô tả skill làm gì + stack specificity (để embedding match chính xác)
when-to-use:
- "trigger phrase 1"
- "trigger phrase 2"
- "keyword tiếng Việt"
---
# Skill Name
## Context
...
## Workflow / Commands
...
## Pitfalls
...
## Code pointers
- `path/to/file.cs`
```
## Tạo skill mới — checklist
1. Tạo folder `.claude/skills/<kebab-case-name>/`
2. Viết `SKILL.md` với frontmatter + sections: Context / Workflow / Code pointers / Common pitfalls
3. Add row vào bảng "Skills hiện có" phía trên
4. Update `docs/CLAUDE.md` (dòng skill count)
5. Commit `[CLAUDE] Skill: add <name>`
## Nguyên tắc design skill
**PROJECT-SPECIFIC, không clone generic:**
- Skill user-level global đã có sẵn (`code-reviewer`, `sql-database-assistant`, `focused-fix`, ...)
- Skill project-level phải encode kiến thức SOLUTION_ERP-only mà generic không có:
- Commit convention `[CLAUDE] <scope>: ...`
- Path pattern `src/Backend/SolutionErp.*/...`
- Pin constraint (MediatR 12.4.1, Swashbuckle 6.9.0, TypeScript 6 erasableSyntaxOnly)
- Gotcha-referenced (dẫn chiếu `docs/gotchas.md#N`)
- Workflow Vietnamese-first
**Keep it actionable:**
- Commands copy-pastable (không pseudocode)
- Paths đầy đủ (không `src/...`)
- Version pinned (không "latest")
- Dẫn chiếu gotcha/migration # cụ thể
