Defined in: types/TableFeatures.ts:161

Validates that every row model and fn registry slot in a features object is accompanied by its prerequisite feature.

Slots whose prerequisite is missing have their type replaced with a literal error message, so the offending property fails to type-check with a message naming the feature that needs to be added.
