# Legacy notes

This package was renamed from OfficeDoc to UnifiedWriter during development.

Legacy storage-specific menu items such as `Open from This Device`, `Save to App Storage`, and built-in Google Drive open/save were removed from the active runtime UI. UnifiedWriter now follows the single-file Control policy:

- the Control owns document parsing, editing, rendering, packaging, import, and export;
- the Host owns file-provider routing through `OpenFile` / `SaveFile` callbacks or Host-side adapters;
- demo pages may implement a local callback only as an integration example.

Old OfficeDoc compatibility is not required during this development phase. Correct UnifiedWriter architecture takes priority over preserving temporary legacy UI hooks.
