Usage notes
- Use this API in the digital signature and PAdES workflow before the affected page, resource, field or catalogue object is finalised
- Keep object names, field names, resource names and returned handles stable until the document is finalised
- Reserve signature space before inserting external CMS or timestamp bytes, and keep byte ranges stable after preparation
- Loaded-document object references may be indirect; resolve arrays, dictionaries, or streams before inspecting nested values
