"""Phase 9 tests: Config settings for accuracy testing & evaluation (Sub-Phase 9.0).

Covers:
- test_results_dir and test_evaluations_dir default values
- eval_chunk_batch_size = 10 (fixed)
- eval_max_concurrent_batches = 10 (rate limiting)
- eval_batch_retry_count = 2
- eval_batch_retry_delay_ms = 2000
- Env var overrides work correctly
