- **Core**:
- Added `check-database.js` to verify database status and validate search functionality.
- Created `fix-dimension-mismatch.js` to handle re-embedding of existing data to resolve dimension mismatch from 3 to 512.
- Improved test cases by updating vector operations to support 512 dimensions, replacing previously hardcoded dimensions.
- **Migration**:
- Developed `DIMENSION_MISMATCH_SUMMARY.md`, detailing the root cause, solution, and preventive strategies for dimension mismatch issues.
- Added `production-migration-guide.md` for structured production migration with detailed steps on re-embedding strategies, batching, and error handling.
- **Tests**:
- Enhanced test coverage with 512-dimensional vector validation.
- Introduced helper functions for consistent vector testing behavior and streamlined search test cases.
- **Documentation**:
- Updated project documentation to highlight the resolution process for dimension mismatches, emphasizing preventive mechanisms such as auto-migration and version tracking.
**Purpose**: Address critical dimension mismatch issues caused by embedding changes, restore functionality, and provide a roadmap for robust prevention strategies and migration processes.
