+**Decision:** ใช้ Application-Level Locking แทน Database Stored Procedure
+
+**Rationale:**
+
+- ยืดหยุ่นกว่า (Template-Based Generator)
+- ง่ายต่อการ Debug และ Monitoring
+- รองรับ Complex Numbering Rules
+- Support ทุกประเภทเอกสาร (LETTER, RFA, TRANSMITTAL, etc.)
+
+**Implementation:**
+
+- **Layer 1:** Redis Redlock (Distributed Lock)
+- **Layer 2:** Optimistic Database Lock (`@VersionColumn()`)
+- **Retry:** Exponential Backoff with Jitter
+- **Counter Key:** Composite PK (8 columns)
