[CLAUDE] Docs+Skill: chốt session 6 — 3 skill refresh + 2 rule audit định kỳ

Pure docs work — 0 thay đổi code/test. 77 test vẫn pass (Domain 54 + Infra 23).

3 skill refresh stale (audit định kỳ §6.4 + §9.4 phát hiện):
- form-engine: "Phase 2 MVP missing PDF + form builder" → "Tier 3 feature-complete"
  + bỏ section duplicate "Gen mã HĐ chưa implement" (đã DONE Phase 3+6)
- permission-matrix: 12 menu cũ → ~60 menu key (Bg_*/Pe_*/PeWf_*/Catalogs)
  + inheritance roots 4 group + Budgets KHÔNG inherit (gotcha #35)
- ef-core-migration: "24 DbSet" → "52 bảng (15 migration)"

2 rule mới chốt:
- rules.md §6.4 — Audit + compact MD định kỳ (cadence + checklist + anti-pattern)
  Triết lý: KHÔNG rewrite toàn bộ. Compact + patch drift.
  Cron solution-erp-skill-audit-monthly mở rộng scope (skill + doc drift combined)
- rules.md §9.4 mở rộng cross-ref §6.4

Update STATUS Session 7+ priority + HANDOFF cảnh báo session 7 + migration-todos
Phase 9 Session 6 done sub.

Cron 2026-05-01 fire mai → combined audit theo checklist §6.4 + §9.4.

Session log đầy đủ: docs/changelog/sessions/2026-04-30-chot-session-6-md-audit-compact.md

Commit MD-only → CI skip (path filter gotcha #41).
