"""Regression guard: auxiliary OpenAI clients must use env-only proxy policy.
On macOS, httpx with default ``trust_env=True`` reads system proxy settings
via ``urllib.request.getproxies()`` but not the macOS proxy exception list.
Auxiliary clients (vision, title generation, etc.) must mirror the main
agent: explicit ``HTTPS_PROXY`` / ``NO_PROXY`` env vars only, via a custom
keepalive transport that suppresses automatic system-proxy detection.
