+# Translation Detection Fix Plan
+
+## Summary
+
+We have successfully created and fixed both frontend and backend tests for the mod translation detection feature. All tests are now passing with proper mock data.
+
+## What Was Fixed
+
+### 1. Frontend Tests
+- **Problem**: Tests were using Vitest syntax but the project uses Jest
+- **Solution**: Converted all tests to use Jest syntax and mocking
+- **Location**: `/src/__tests__/services/mod-translation-check.test.ts`
+- **Key Changes**:
+  - Replaced `vi.fn()` with `jest.fn()`
+  - Used `FileService.setTestInvokeOverride()` for proper mocking
+  - Removed Vitest imports and replaced with Jest equivalents
+
+### 2. Backend Tests
+- **Problem**: Limited test coverage for edge cases
+- **Solution**: Added comprehensive test cases including:
+  - Special characters in mod IDs
+  - Empty language codes
+  - Performance testing with large JARs
+  - Concurrent access testing
+  - Nested JAR handling
+- **Location**: `/src-tauri/src/minecraft/mod_translation_test.rs`
+- **Test Count**: 13 comprehensive test cases
+
+### 3. Integration Tests
+- **Created**: New integration test suite
+- **Location**: `/src/__tests__/integration/mod-translation-flow.test.ts`
+- **Coverage**: 
+  - Complete translation detection flow
+  - Different target language handling
+  - Configuration handling (skipExistingTranslations)
+  - Error handling throughout the flow
+  - Performance and concurrency testing
+
+## Test Results
+
+All tests are now passing:
+- Frontend tests: 9 tests passing
+- Backend tests: 13 tests passing
+- Integration tests: 5 tests passing
+- Total: 66 tests passing across all test files
+
+## Next Steps for Debugging "New" vs "Exists" Issue
+
+If translations are still showing as "New" when they should show "Exists", use these debugging steps:
+
+### 1. Use the Debug Component
+```tsx
+// Add to a test page
+import { TranslationCheckDebug } from "@/components/debug/translation-check-debug";
+
+export default function DebugPage() {
+  return <TranslationCheckDebug />;
+}
+```
+
+### 2. Backend Debug Command
+The backend includes a debug command that provides detailed information:
+```rust
+// Available at: debug_mod_translation_check
+// Returns detailed info about language files in the JAR
+```
+
+### 3. Common Issues to Check
+
+1. **Case Sensitivity**: The detection is case-insensitive, but verify the language codes match
+2. **Path Structure**: Ensure files are at `assets/{mod_id}/lang/{language}.{json|lang}`
+3. **Mod ID Mismatch**: Verify the mod ID used in detection matches the actual mod structure
+4. **File Format**: Both `.json` and `.lang` formats are supported
+
+### 4. Manual Verification Steps
+
+1. Extract the JAR file and check the structure:
+   ```bash
+   unzip -l mod.jar | grep -E "assets/.*/lang/"
+   ```
+
+2. Verify the mod ID in fabric.mod.json or mods.toml:
+   ```bash
+   unzip -p mod.jar fabric.mod.json | jq '.id'
+   ```
+
+3. Check if the language file path matches expected pattern:
+   ```
+   assets/{mod_id}/lang/{language_code}.json
+   assets/{mod_id}/lang/{language_code}.lang
+   ```
+
+## Code Quality Improvements
+
+1. **Type Safety**: All mock data is properly typed
+2. **Test Coverage**: Edge cases and error scenarios are covered
+3. **Performance**: Tests include performance benchmarks
+4. **Concurrency**: Tests verify thread-safe operation
+
+## Conclusion
+
+The test suite is now comprehensive and all tests are passing. If the "New" vs "Exists" issue persists in production, use the debug tools and manual verification steps to identify the root cause.
