A full save() of a Document instance loaded before another process moved its file wrote the old filename back. The DB then pointed at a path that no longer existed, and recovery only worked when the recomputed path happened to match the file's real location.
Document.save() now leaves filename and archive_filename out of full saves on existing rows. Writers that own those columns opt in with write_file_paths=True or an explicit update_fields. A full save of a row deleted elsewhere now raises instead of re-inserting it.
The model factories lived in the documents test package, but three other
apps needed them. The AI, mail and testing suites all reached across an app
boundary to import from documents.tests.factories, which made a private test
package into a shared dependency.
The factories now live in the shared testing package, where cross-app use is
the intended use.
