Arms: Anthropic baseline, GLM on Together, Kimi on OpenRouter (DeepSeek
and Qwen staged, disabled). Six briefs incl. metric-temptation,
component-scope, and vision-probe probes. Floor-only vs full skill packs
to measure prompt bloat. run-matrix orchestrates gen, shots, score,
judge, report; the repair loop feeds sloplint FAILs back to the model.
