+# Session History: 2025-12-24 - Document Numbering Fixes
+
+## Overview
+- **Date:** 2025-12-24
+- **Duration:** ~2 hours
+- **Focus:** Document Numbering System - Bug Fixes & Improvements
+
+---
+
+## Changes Made
+
+### 1. Year Token Format (4-digit)
+**Files:**
+- `backend/src/modules/document-numbering/services/format.service.ts`
+
+**Changes:**
+```typescript
+// Before
+'{YEAR}': year.toString().substring(2),      // "25"
+'{YEAR:BE}': (year + 543).toString().substring(2),  // "68"
+
+// After
+'{YEAR}': year.toString(),          // "2025"
+'{YEAR:BE}': (year + 543).toString(),  // "2568"
+```
+
+---
+
+### 2. TypeScript Field Name Fixes
+**Files:**
+- `backend/src/modules/document-numbering/dto/preview-number.dto.ts`
+- `backend/src/modules/document-numbering/controllers/document-numbering.controller.ts`
+- `frontend/lib/api/numbering.ts`
+- `frontend/components/numbering/template-tester.tsx`
+
+**Changes:**
+- `originatorId` → `originatorOrganizationId`
+- `typeId` → `correspondenceTypeId`
+
+---
+
+### 3. Generate Test Number Bug Fix
+**Root Cause:**
+1. API client ใช้ NextAuth `getSession()` แต่ token อยู่ใน Zustand localStorage (`auth-storage`)
+2. Response wrapper mismatch: backend ส่ง `{ data: {...} }` แต่ frontend อ่าน `res.data` โดยตรง
+
+**Files:**
+- `frontend/lib/api/client.ts` - ดึง token จาก `localStorage['auth-storage']`
+- `frontend/lib/api/numbering.ts` - แก้ response unwrapping: `res.data.data || res.data`
+
+---
+
+### 4. Documentation
+**Files Created/Updated:**
+- `docs/document-numbering-summary.md` - Comprehensive system summary
+
+---
+
+## Verification Results
+
+| Test                 | Result    |
+| -------------------- | --------- |
+| Backend Build        | ✅ Pass    |
+| Frontend Build       | ✅ Pass    |
+| Generate Test Number | ✅ Working |
+

+## Notes
+- Template ต้องใช้ `{YEAR:BE}` เพื่อแสดงปี พ.ศ. (ไม่ใช่ `{YEAR}`)
+- สามารถแก้ไข Template ผ่าน Admin > Numbering > Edit Template
