- extract preprocessing config factories into tests/data/factories.py - keep conftest.py fixtures-only; stop importing builders from it - promote temp_dir fixture to root conftest for cross-directory reuse - unify duplicate BPE tokenizer builders into build_test_tokenizer - merge grpo/dpo online e2e tests into one parametrized integration test - extract engine mock factory and shared model batch builders - drop local tempfile usage in favor of shared fixtures No behavior change: 519 tests pass.
