"""Venice host-allowlist behavior (follow-up to provider support).

Venice (https://api.venice.ai/api/v1) is a paid, OpenAI-compatible cloud API
with native tool-calling. These tests pin the three host-list integrations:
  - agent loop sends native tool schemas to Venice (not fenced-block parsing),
  - teacher escalation treats Venice as SOTA (loop OFF, no added latency).
