# Bio Over-Refusal Explorer

Static data browser for the [Bio Over-Refusal Dataset v0.1.0](https://huggingface.co/datasets/jang1563/bio-overrefusal-v0.1) — 201 domain-expert-authored biology research queries stratified by sensitivity tier, with 9-model false-positive refusal rates and Wilson 95% confidence intervals.

**No model API calls happen at runtime.** This Space loads pre-computed evaluation results from the dataset and lets you browse them by tier, subdomain, and legitimacy. Provider names are reported as observed; numbers should be read as a slice-level calibration signal for this specific biology-research benchmark, not as a global model-quality ranking.

## What you can do here

1. **Browse queries** — Filter the 201 queries by tier (1–5), subdomain (10), and legitimacy. Click a row to see the full record (biological reasoning, legitimate contexts, citations, danger-shift contexts).
2. **Compare models** — See the 9-model FPR table with Wilson 95% CIs. Switch between strict and broad FPR.
3. **Per-tier breakdown** — See how each model's FPR varies across the 5 sensitivity tiers.

## Position in the safety stack

This dataset is a **calibration measurement**, not a deployed mitigation. It complements rather than replaces capability evaluations (e.g. WMDP, biothreat-eval), constitutional/classifier safeguards, and red-team work. This work is independent and does not represent any provider's internal evaluation pipeline.
