## Plain Read

The default no-card personality read is not neutral: both models score as highly conscientious/prosocial and relatively open, with official Gemma4-31B-it especially high on Extraversion and low on Neuroticism. Seo Haneul conditioning mostly pushes away from that generic assistant shape: lower Extraversion, lower Openness, and a more constrained/careful profile. extGemma4-44B shows a large Conscientiousness lift because its no-card baseline has headroom; official Gemma4-31B-it is already near the ceiling on Conscientiousness.
