Leaning-stratum gaps — 0.51 to 0.72

Preregistered trait-rule strata differ by 0.510–0.719 across conditions; bundle contrasts, not trait causality.

Leaning label assigned from generated traits before any behavior existed · 8 vs 8 prompts

The preregistered leaning rule (cooperative-leaning iff at least two of agreeable, patient, risk-averse) divides the panel 8/8 by construction. Descriptive gaps:

These are fixed-panel prompt-bundle contrasts. The confirmatory unit is the complete persona sentence; names, ages, and occupations are uncontrolled semantic components, so no causal trait effect is claimed.
