This exact package was already imported by a completed trans

Error message

This exact package was already imported by a completed transfer. Re-export the package to import it again.

What it means

Idempotency guard in the import transfer flow: the server reports that a completed transfer with this exact content hash already exists, so the client refuses to re-upload/re-import the identical package. Re-exporting the package produces a new hash and is required to import again.
