# Prefers an interpreter that ALREADY has pytest + python-dotenv (the repo's
# backend venv, then the ambient python3) so the check needs no uv cache,
# network, or ~/.cache write — keeping `make preflight` green in restricted
# local/agent environments. Only a truly bare environment falls back to uv,
# and even then the cache is redirected to a writable temp dir. Real pytest
# failures still fail the lane in every path.
