  "Description": "Implements 'SelectBoost'-style variable selection\nworkflows for functional data analysis. The package provides\nFDA-native design and preprocessing objects for raw curves,\nspline-basis expansions, Functional principal component\nanalysis scores, and scalar covariates; grouped\nstability-selection routines based on repeated subject-level\nsubsampling; multiple selector backends including lasso, group\nlasso, and sparse-group lasso; FDA-aware grouping functions and\ncalibration helpers for 'SelectBoost'; method-comparison\nutilities; a formula interface; simulation, benchmarking, and\nvalidation helpers with mapped ground truth; targeted\nsensitivity-study utilities and shipped benchmark summaries for\nmean 'F1' comparisons between FDA-aware and plain 'SelectBoost'\nworkflows; small example datasets; and an optional adapter to\nthe native stability-selection interface from the 'FDboost'\npackage.",
