Deduplicating Correlated Evidence Breaks Calibration: A Shrinkage Correction for Quorum-Validated Multi-Agent Alerts

Removing correlated evidence creates the small-sample regime that breaks the naive confidence estimator; a shrinkage estimator makes calibration nearly invariant to the contamination rate. Expected calibration error: ECE 0.334 → 0.128. Files are under restricted access. Metadata, authorship and date are public; access to the full text is granted on request.

Abstract

Removing correlated evidence creates the small-sample regime that breaks the naive confidence estimator; a shrinkage estimator makes calibration nearly invariant to the contamination rate. Expected calibration error: ECE 0.334 → 0.128. Files are under restricted access. Metadata, authorship and date are public; access to the full text is granted on request.
