# Compare Models Blindly Compare usable outputs without revealing model identity, teacher answers, latency, or prior scores to the judge. ## Freeze the comparison set Select cases by predefined metadata and stable input order before inspecting outcomes. Record the manifest. Reuse saved inference when available; do not rerun a model merely to prepare judging. Validate candidates independently before strategic or qualitative judging. A candidate that fails identifier, replay, terminal-boundary, or other safety gates cannot win. ## Build the blinded packet Input rows should contain shared case context and two candidate fields. Run: ```sh python scripts/blind_candidates.py disagreements.jsonl \ --id-field id --left-field modelOne --right-field modelTwo \ --seed experiment-v1 \ --cases-output blinded-cases.jsonl \ --mapping-output identity-mapping.json ``` Store the mapping separately. Do not consult it during judging. The script uses a SHA-256-derived assignment per case, so reruns with the same seed and IDs are stable. ## Judge twice 1. Judge Candidate A and Candidate B using only supplied context and a fixed controlled rubric. 2. Create a second pass with candidate order reversed. 3. Keep explanations compact and evidence-grounded; do not request chain-of-thought. 4. Translate both verdicts to underlying candidate identity. Award a preference only when both orders select the same underlying candidate. Otherwise classify the case as order-sensitive. Preserve t
