CIPHER Cross-Record Inference - FIR (Zero-Shot): leaderboard

Cross-record inference over privacy-hardened police First Information Reports whose narratives were masked with typed placeholders, from CIPHER (Roy Chowdhury et al., 2026): expert-validated questions combine structured fields with free-text narratives across 39 to 42 supplied records, answered with zero-shot prompting. Harmonic answer score in percent, the per-question harmonic mean of token overlap and Gemini 2.5 Flash acceptance; higher is better.

Metric: Harmonic answer score (%; per question the harmonic mean of token overlap with the reference and Gemini 2.5 Flash semantic acceptance, zero when rejected, averaged; First Information Reports (Indian police records) with typed placeholders from post-hoc masking; the full support-controlled context of 39-42 records including distractors; zero-shot prompting; greedy decoding).
