- Remove DatabaseService abstraction layer from API routes
- Implement FastAPI dependency injection for repositories
- Create leggen/api/dependencies.py with factory functions
- Update routes to use AccountRepo, BalanceRepo, TransactionRepo directly
- Refactor SyncService to use repositories instead of DatabaseService
- Deprecate DatabaseService with warnings for backward compatibility
- Update all tests to use FastAPI dependency overrides pattern
- Fix mypy type errors in routes
Benefits:
- Simpler architecture with one less abstraction layer
- More explicit dependencies via function signatures
- Better testability with FastAPI's app.dependency_overrides
- Clearer separation of concerns
All 114 tests passing, mypy clean.
Split the monolithic DatabaseService (1,492 lines) into focused repository
modules using the repository pattern for better maintainability and
separation of concerns.
Changes:
- Create new repositories/ directory with 5 focused repositories:
- TransactionRepository: transaction data operations (264 lines)
- AccountRepository: account data operations (128 lines)
- BalanceRepository: balance data operations (107 lines)
- MigrationRepository: all database migrations (629 lines)
- SyncRepository: sync operation tracking (132 lines)
- BaseRepository: shared database connection logic (28 lines)
- Refactor DatabaseService into a clean facade (287 lines):
- Delegates data access to repositories
- Maintains public API (no breaking changes)
- Keeps data processors in service layer
- Preserves require_sqlite decorator
- Update tests to mock repository methods instead of private methods
- Fix test references to internal methods (_persist_*, _get_*)
Benefits:
- Clear separation of concerns (one repository per domain)
- Easier maintenance (changes isolated to specific repositories)
- Better testability (repositories can be mocked individually)
- Improved code organization (from 1 file to 7 focused files)
All 114 tests passing.
Introduces a DataProcessor layer to separate transformation logic from orchestration and persistence concerns:
- Created data_processors/ directory with AccountEnricher, BalanceTransformer, AnalyticsProcessor, and moved TransactionProcessor
- Refactored SyncService to pure orchestrator, removing account/balance enrichment logic
- Refactored DatabaseService to pure CRUD, removing analytics and transformation logic
- Extracted 90+ lines of analytics SQL from DatabaseService to AnalyticsProcessor
- Extracted 80+ lines of balance transformation logic to BalanceTransformer
- Maintained backward compatibility - all 109 tests pass
- No API contract changes
This improves code clarity, testability, and maintainability while maintaining the existing API surface.

Frontend:
- Memoize pagination object in TransactionsTable to prevent unnecessary re-renders and fix exhaustive-deps warning
- Add optional success and message fields to backup API response types for proper error handling
Backend:
- Add TypedDict for transaction type configuration to improve type safety in generate_sample_db
- Fix unpacking of amount_range with explicit float type hints
- Add explicit type hints for descriptions dictionary and specific_descriptions variable
- Fix sync endpoint return types: get_sync_status returns SyncStatus and sync_now returns SyncResult
- Fix transactions endpoint data type declaration to properly support Union types in PaginatedResponse
All checks now pass:
- Frontend: npm lint and npm build ✓
- Backend: mypy type checking ✓
- Backend: ruff lint on modified files ✓

Fixed scheduled syncs being incorrectly saved as "manual" in database.
Now properly identifies scheduled syncs as "scheduled" and retry
attempts as "retry". Updated frontend to capitalize trigger type
badges for better display.
