Optimistic Updates Rollback (frontend) - Added rollback logic to useFolderOperations mutations - enableAITaggingMutation now saves previousFolders and restores on error - disableAITaggingMutation now saves previousFolders and restores on error - Ensures UI state consistency when mutations fail 2. Remove Double Metadata Parsing (backend) - Removed redundant image_util_parse_metadata call in routes/images.py - Metadata now parsed only once in db_get_all_images() - Eliminates unnecessary overhead and potential errors - Metadata correctly returned as dict from database layer 3. Fix Table Creation Order (backend) - Reordered table creation to respect foreign key dependencies - images table now created before faces, album_images, and metadata - Prevents FK constraint violations when PRAGMA foreign_keys = ON - Applied fix to main.py and test fixtures (conftest.py, test_images.py) 4. Fix Query Refetch Logic (frontend) - Changed autoInvalidateTags to iterate and refetch each tag separately - Prevents passing entire array as single composite queryKey - Ensures proper cache invalidation for each query Testing: - Frontend: TypeScript compiles with 0 errors, all Jest tests pass (6/6) - Backend: 19/20 pagination tests pass, 2/2 metadata tests pass - Added test_metadata_fix.py to verify metadata structure - Fixed test_images.py fixture to properly create test database Files modified: - backend/app/routes/images.py (remove double parsing) - backend/main.py (fix table order) - backend/tests/conftest.py (fix table order) - backend/tests/test_images.py (fix test fixtures) - backend/tests/test_metadata_fix.py (new verification tests) -

Before: if limit is not None and offset is not None and offset > MAX_OFFSET_VALUE After: if offset is not None and offset > MAX_OFFSET_VALUE This ensures that requests with a large offset but no limit are correctly rejected, preventing potential performance issues.

Issues fixed: 1. AvatarSelectionStep - useEffect missing deps, re-dispatching on every render 2. FolderSetupStep - useEffect missing deps, re-dispatching on every render 3. ThemeSelectionStep - useEffect missing deps, re-dispatching on every render 4. ServerCheck - missing dispatch/stepIndex dependencies 5. InitialSteps - missing navigate dependency Solution: - Added hasMarkedCompleted flag to prevent re-dispatching markCompleted - Added proper useEffect dependencies (dispatch, stepIndex, navigate) - Prevents infinite loop: useEffect -> dispatch -> state change -> re-render -> useEffect This fixes issue #645 where the bundled app fails to launch on macOS Apple Silicon due to infinite recursion in the login/onboarding page.
