Instance Method Details

#entity_bearing?(native, doc = nil) ⇒ Boolean

Marker presence is a document-level fact: parse records it, the ER builder path flips it, and the split/restore scans consult it. Customized natives only exist as split products of marker-bearing text, so they always report true. doc is the binding document when the wrapper could resolve it through its parent chain; the C climb is the fallback.

Returns:

  • (Boolean)
