+# Session History - 2025-12-23: Document Numbering Form Refactoring
+
+## Objective
+Refactor and debug the "Test Number Generation" (Template Tester) form to support real API validation and master data integration.
+
+## Key Changes
+
+### 1. Frontend Refactoring (`template-tester.tsx`)
+- **Master Data Integration**: Replaced manual text inputs with `Select` components for Originator, Recipient, Document Type, and Discipline.
+- **Dynamic Data Hook**:
+    - Integrated `useOrganizations`, `useCorrespondenceTypes`, and `useDisciplines`.
+    - Fixed empty Discipline list by adding `useContracts` to fetch active contracts for the project and deriving `contractId` dynamically.
+- **API Integration**: Switched from mock `generateTestNumber` to backend `previewNumber` endpoint.
+- **UI Enhancements**:
+    - Added "Default (All Types)" and "None" options to dropdowns.
+    - Improved error feedback with a visible error card if generation fails.
+- **Type Safety**:
+    - Resolved multiple lint errors (`Unexpected any`, missing properties).
+    - Updated `SearchOrganizationDto` in `organization.dto.ts` to include `isActive`.
+
+### 2. Backend API Harmonization
+- **DTO Updates**:
+    - Refactored `PreviewNumberDto` to use `originatorId` and `typeId` (aligned with frontend naming).
+    - Added `@Type(() => Number)` and `@IsInt()` to ensure proper payload transformation.
+- **Service Logic**:
+    - Fixed `CounterService` mapping to correctly use the entity property `originatorId` instead of the DTO naming `originatorOrganizationId` in WHERE clauses and creation logic.
+    - Updated `DocumentNumberingController` to map the new DTO properties.
+
+### 3. Troubleshooting & Reversion
+- **Issue**: "Format Preview" was reported as missing.
+- **Action**: Attempted a property rename from `formatTemplate` to `formatString` across the frontend based on database column naming.
+- **Result**: This caused the entire Document Numbering page to fail (UI became empty) because the backend entity still uses the property name `formatTemplate`.
+- **Resolution**: Reverted all renaming changes back to `formatTemplate`. The initial "missing" issue was resolved by ensuring proper prop passing and data loading.
+
+## Status
+- **Test Generation Form**: Fully functional and integrated with real master data.
+- **Preview API**: Validated and working with correct database mapping.
+- **Next Steps**: Monitor for any further data-specific generation errors (e.g., Template format parsing).
