 ## Files
 
 All files of a release live under `<version>/` (this card: `v1.0/`); the git tag `v1.0` freezes the data. The
 **evidence supplement** (every run with per-query metrics and meta, all LLM-audit records including the extended
 audit and pools, and the fine-tuned bi-encoder weights) is under `v1.0/experiments/` and frozen by the tag

 **Baseline protocol caveat.** Fine-tuning on the training split with BM25 hard negatives mined across the whole
