Why it missed

Answer extraction errorThe downloaded Galaxy table is byte-identical to the two passing replicates and its minimum coefficient is CDKN1A at -0.5234. The agent mis-sorted or misread that completed table and reported USP54.

Why it missed

Essentiality direction was not convertedThis run ranked expression against the negative-going raw CRISPR gene-effect score and selected CCND1. Converting gene effect to positive-going essentiality changes the requested strongest negative correlation to CDKN1A.
