   post-launch. Pending migrations: PaymentTermFields + DepartmentOpinions
   + CodeSequences.
 - architecture.md — Section 9 PurchaseEvaluation module (ERD + workflow
   A/B + kế thừa HĐ flow).
 - CLAUDE.md (root) — 5 file đọc đầu (thêm HANDOFF), Modules table, 12
   migration 46 bảng, +PurchaseEvaluation commit scope.

   * contract-workflow: note PE workflow tách table riêng
   * permission-matrix: +Pe_*/PeWf_* menu keys + TODO grant non-admin
