"""Unit tests for Step 1 file classification (_classify_file).

These tests call the real LLM so they require OPENAI_API_KEY / LLM env vars.
Run with: pytest tests/test_classify_file.py -v

To run a quick manual check against a real file without the full UI:
    python -m tests.test_classify_file <path/to/file.txt> [project_name...]
