- Add app/tasks/upload_to_user_integration.py: new Celery task that
uploads a processed document to a specific UserIntegration using its
own per-user config and Fernet-decrypted credentials. Supports all
DESTINATION types: Dropbox, S3, Google Drive, OneDrive, WebDAV,
Nextcloud, FTP, SFTP, Paperless-ngx, Email (SMTP), and Rclone.
- Extend app/tasks/send_to_all.py: add send_to_user_destinations task
(queries active DESTINATION UserIntegrations for an owner and
dispatches one upload_to_user_integration task per integration) and
get_user_destination_count helper used by finalize_document_storage.
- Refactor app/tasks/finalize_document_storage.py: after processing,
look up the document owner; if the owner has active DESTINATION
integrations route exclusively to those (user-specific routing),
otherwise fall back to the global send_to_all_destinations.
- Update tests/test_finalize_storage.py: add autouse fixture to prevent
Redis hangs, update all existing tests with new mock parameters, add
TestFinalizeDocumentStorageUserRouting class with four new tests that
validate user-specific vs global routing decisions.
- Add tests/test_user_integration_upload.py: 14 new unit tests covering
upload_to_user_integration (handler dispatch, error persistence,
last_used_at update, credential decryption, skip for unknown types)
and send_to_user_destinations / get_user_destination_count.
- Update docs/StorageArchitecture.md: document the user-specific
destination routing feature, supported types, multiple-destination
behaviour, and global fallback semantics.
