Overview

Registry of entity types (host ActiveRecord models) that have opted into typed fields via ‘has_typed_eav`. Tracks optional field-type restrictions per entity.

Populated automatically when a host model calls ‘has_typed_eav`; read by Field::Base#validate_type_allowed_for_entity to enforce restrictions on field creation.
