"""
Live-integration tests for the XecGuard guardrail.
These tests issue real HTTP requests against the XecGuard production
endpoint. They are skipped by default. To run them, set both:
XECGUARD_RUN_LIVE=1
XECGUARD_API_KEY=<your xgs_* service token>
Optional: XECGUARD_API_BASE (defaults to https://api-xecguard.cycraft.ai).
Example:
XECGUARD_RUN_LIVE=1 \
XECGUARD_API_KEY=xgs_xxx \
/home/clyang/ll999/bin/pytest \
tests/test_litellm/proxy/guardrails/guardrail_hooks/test_xecguard_live.py -v
