%description
Identifies candidate item sets through threshold-driven iterative removal
searches in exploratory factor analysis. Provides a no-removal baseline,
numerical diagnostics, factor reliability, holdout evaluation, and
bootstrap search stability to support transparent screening and documented
content review rather than automatic measurement decisions. The loading
criteria are based on best practices and established heuristics (e.g.,
Costello & Osborne (2005) <doi:10.7275/jyj1-4868>, Howard (2016)
<doi:10.1080/10447318.2015.1087664>). Includes flexible thresholds for
factor loadings (min_loading) and cross-loading differences
(loading_diff).
