- [x] Inspected test suites in `tests/unit/` (`test_challenger_chat_m2.py`, `test_challenger_m2_chat_adversarial.py`) and `tests/e2e/` (`test_ui_typography_i18n_wiki_streamlining_e2e.py`, `test_chat_distributed_system_e2e.py`).
- [x] Tested python, pytest (9.1.1), node (v24.14.0), npm (11.9.0), and playwright (`channel='msedge'`).
