notes: Entity-relationship graph derived from the Business Documents API v3 schemas (176 entities). The published
  spec is fully dereferenced (no $ref), so relationships are detected from inline reference objects — properties
  shaped as {id} objects (belongs_to) or arrays of {id} objects (has_many). "to" is the matched schema name where
  one exists, otherwise the field name.
