+### 🔄 ADR-019 Hybrid UUID Migration (Mar 2026)
+
+- ✅ **Phase 1-4**: Schema, entities, API layer — all 14 tables migrated
+- ✅ **Phase 5 (Partial)**: Frontend routes, services, hooks migrated to UUID
+- ✅ Drawing search: `projectUuid` sent to backend, resolved in controller
+- ✅ Drawing detail page: mock API replaced with real UUID-based services
+- 🔄 **Phase 5.4 (Pending)**: FK reference UUID migration — `correspondences/form.tsx`, `user-dialog.tsx`, `numbering/template-tester.tsx`, `rfas/page.tsx` still use `parseInt()` on UUID values (see `specs/05-Engineering-Guidelines/05-07-hybrid-uuid-implementation-plan.md`)
+- 📋 **Phase 6**: Unit + integration tests for UUID-based routes
+
 ### 🔄 Next: Go-Live Preparation
 
 - 🔄 **UAT**: ทำ User Acceptance Testing ตาม `01-05-acceptance-criteria.md`
