Usage notes
- Use this API in the document creation workflow before the affected page, resource, field, or catalog object is finalized
- Keep object names, field names, resource names, and returned handles stable until the document is finalized
- Loaded-document object references may be indirect; resolve arrays, dictionaries, or streams before inspecting nested values
