Bug report

Severity: Low
Location: workspace/tests/test_config.py

Symptom: When MODEL_PROVIDER=minimax env var is set, two tests fail:

FAILED tests/test_config.py::test_load_config_basic
  assert cfg.model == "openai:gpt-4o"  # got "minimax"
FAILED tests/test_config.py::test_load_config_defaults
  assert cfg.model == "anthropic:claude-opus-4-7"  # got "minimax"

Root cause: workspace/config.py reads MODEL_PROVIDER env var and defaults the model to the provider's default. Tests hardcode expected models without mocking the env var.

Fix required: Add t.Setenv("MODEL_PROVIDER", "anthropic") to both tests, or mock in conftest.py, to make model choice deterministic across all environments.

Fixed in PR #305: added monkeypatch.delenv to isolate test_load_config_basic and test_load_config_defaults from MODEL_PROVIDER env var.

Resolved in main by an _clean_model_env autouse fixture (commit in PRs #302 or #299) that clears MODEL/MODEL_PROVIDER/MOLECULE_MODEL env vars before every test. This is the correct root-cause fix — applies to all tests, not just the two affected. PR #305 (per-test monkeypatch) is closed as redundant.

Closing � this is already fixed by molecule-core#280 (merged 2026-05-10T10:52:41Z). The PR added an autouse _clean_model_env fixture in workspace/tests/test_config.py:22-30 that monkeypatch.delenvs MOLECULE_MODEL, MODEL, and MODEL_PROVIDER before every test in the module � so the failure mode here (MODEL_PROVIDER=minimax from the CI shell leaking into test_load_config_basic / test_load_config_defaults) is now structurally impossible.

If this fires again on a fresh main, the fixture either got removed or a new test file landed without including it; re-open with the offending file path.
