pqhuy1987 881783c335 [CLAUDE] Docs: S96 monthly drift audit + FD memory distill + mega-line re-tier
Monthly drift audit (2026-07-01, cron ngày 1) — workflow-prepared (wf_2d687d27-175, 4 clusters draft→adversarial-verify), em-main single-writer applied:
- ef-core-migration/SKILL.md: latest-mig 56→59 + append table rows 57/58/59 + Mig 14 + Phase-7 Budget annotate DROPPED Mig 50 (S61)
- skills/README.md: ef-core row Mig 55→59/S87 + gotcha cite #69→#76 (5 latest, authoritative gotchas.md headings)
- docs/CLAUDE.md: Budget module marked REMOVED Mig 50 — §1 item 6 + roadmap Phase 7/8 rows (strike-through, non-destructive)
- docs/governance/vocab-alias-map.md (NEW): 3 vocab-forks documented (run-trace / Ngân sách PRO / all-inherit canonical) + governance-detectors.ps1 $ExcludeExact entry (anti self-match)
- re-tier STATUS/HANDOFF mega-line 5→3 blurbs (S92/S91 → archive verbatim, conservation delta=0, BOM preserved) + hoist 3 UAT-carry items to blockers

FD memory distill (H17 loop strike-1 → CLEARED, GAPS: none):
- frontend-designer L1 26129B→21492B: 5 old Activity war-stories → archive/2026-06.md + _INDEX + gist; Lessons value-protect distilled to L1
- budget.json measured.frontend-designer refreshed

Detector 27→25 (2 real drift cleared; remaining = documented false-positives module-local/never-built-defer). AS-10 residual reviewer sub-write reverted (git-diff backstop, E-006 recurrence — guard HELD).

# CLAUDE.md — Full Context (SOLUTION_ERP)
## 1. Giới thiệu
**SOLUTION_ERP** là hệ thống quản lý Hợp đồng Nhà cung cấp / Thầu phụ / Tổ đội / Dịch vụ + **Phiếu Duyệt NCC tiền-HĐ** cho **Công ty TNHH Xây dựng Solutions**, thay thế quy trình giấy / Word+Excel hiện tại.
**Scope chính:**
1. Số hóa 8 form hợp đồng (template engine điền field → export .docx/.xlsx)
2. Workflow 9 phase trình ký HĐ (state machine + role guard + SLA auto-approve + versioned WF per ContractType)
3. Tự gen mã HĐ theo Quy định SOL-CCM-RG-001
4. Dashboard báo cáo HĐ theo NCC, dự án, trạng thái, giá trị
5. **Module Duyệt NCC (Phase 6-8)** — phiếu trình duyệt so sánh giá tiền-HĐ, 2 quy trình A/B versioned admin-config, kế thừa HĐ 1-click khi DaDuyet, Ý kiến 4 phòng ban sign-off
6. ~~**Module Ngân sách (Phase 7-8)** — 4 bảng quản lý ngân sách dự án, workflow simple 3-step, integration link với Contract & PE + cột "So với ngân sách" PE matrix~~ ⚠️ **REMOVED Mig 50 (S61)** — module Budget cũ (4 bảng Budgets/BudgetDetails/BudgetApprovals/BudgetChangelogs) XÓA, thay bằng **ngân sách per-gói-thầu `PeWorkItemBudgets`** (1 record/cặp Dự án × Hạng mục, nhập theo role PRO/CCM); FE pages/types/menu `Bg_*` gỡ hết.
7. **Test gate (Phase 8)** — xUnit Domain policy + Infra code generator, CI fail-fast no deploy

## 7. Quy ước code
- **Ngôn ngữ UI:** 100% tiếng Việt. Code + comment + tên DB table: **English**.
- **Tên file:** PascalCase cho `.cs`, kebab-case cho TS/TSX (trừ React component = PascalCase).
- **Null safety:** `.NET` bật nullable reference types. TS `strict: true`.
- **Async/await** cho mọi I/O.
- **Error handling BE:** `GlobalExceptionMiddleware` → map exception → ProblemDetails. KHÔNG try-catch ở controller.
- **Error handling FE:** error boundary + toast. Dùng `useErrorHandler` hook.
- **Logging:** Serilog structured. Không `Console.WriteLine`.
## 8. Security baseline
- HTTPS everywhere (IIS redirect HTTP → HTTPS)
- JWT expiry 1h, refresh token 7d
- Password hash: Identity default (PBKDF2)
- CORS: whitelist chỉ 2 FE origin
- Rate limit: 100 req/min/IP cho endpoint auth
- SQL injection: EF Core parameterized (không raw SQL trừ khi cần)
- Audit log: mọi write → `AuditLog` table
