"""Run and score generation prompts (the quality side of the evaluation).
Perplexity says nothing about refusals, persona drift, or instruction following.
This harness is deliberately model-agnostic: it drives whatever CLI generates
text, then scores the outputs with explicit, auditable rules.
# 1. generate: any command template, {prompt} is substituted
python scripts/eval_generation.py generate \
--prompts research/eval_prompts_ja.jsonl \
--out out/gen_ja.jsonl \
--command 'uzu cli --model models/x -m {prompt}'
# 2. score
python scripts/eval_generation.py score \
--prompts research/eval_prompts_ja.jsonl \
--responses out/gen_ja.jsonl \
--json out/score_ja.json
Rules live in ``REFUSAL_PATTERNS`` and ``score_item``; change them there and the
numbers stay reproducible.
