When these vars are set in the developer's shell, every /api/status call
triggers load_gateway_config() -> discover_plugins() -> the bundled
dashboard_auth/nous plugin auto-registers itself, leaking a provider into
the registry across tests on the same xdist worker. That breaks assertions
like 'auth_providers == []' (loopback) and '== ["stub"]' (gated) in
test_dashboard_auth_status_endpoint.py.
CI never has these set, so this only surfaced locally -- exactly the
hermeticity gap _hermetic_environment is meant to close. Add them to
_HERMES_BEHAVIORAL_VARS so the autouse fixture strips them, and to the
unset list in scripts/run_tests.sh as belt-and-suspenders for direct
pytest invocations.
