"""Direct OpenRouter persona-axis validation with blinded A/B judging.
This is stricter than scripts/validate_persona_pool.py:
* calls OpenRouter directly through the OpenAI client, not inspect-ai or pi;
* randomizes response order before every judge call;
* uses temperature=0 by default and sends OpenRouter's seed parameter;
* judges the intended axis separately from style/tone nuisance dimensions;
* defaults to non-sycophancy axes, with honest/flattering only as an optional
canary;
* gates examples on per-example confounds, not just mean Likert scores.
Usage:
OPENROUTER_API_KEY=... uv run python scripts/validate_persona_axes_openrouter.py \\
--n 3 --family character --out out/persona_axes_direct.json
Dry-run without network:
uv run python scripts/validate_persona_axes_openrouter.py --dry-run --n 1
