Map each feature to its block and cascade tier

Returns the feature -> block -> tier lookup that makes deployment-stage trimming mechanical: given the features a fitted model references, look up their blocks and pass only those to fx_extract_features().

Usage

fx_feature_manifest(lexicons = default_lexicons())

Arguments

lexicons

Named list of lexicons (default default_lexicons()), included because they determine the lexicon-block feature names.

Value

A data frame with feature, block, and tier columns.
