 - Service abstraction with provider pattern (audio, TTS, LLM)
 - Configuration-driven behavior with fallback defaults
 
-## Testing Approach
-
-**Current State**: Test directory removed, but `.pytest_cache` indicates pytest was used.
-
-**If adding tests**:
-- Place tests in `tests/` directory at project root
-- Follow pytest conventions
-- Use `pytest.fixture` for shared test resources
-- Mock external dependencies (audio, TTS, LLM providers)
-- Test configuration overrides via `ConfigContext`
-
-**Testable Components**:
-- Algorithm implementations (FSRS, SM2)
-- Puzzle logic validation
-- Configuration loading and saving
-- Atom persistence and evaluation
