Its upload mirrors the working folder with --delete-after, and a folder on another laptop held none of the APKs released from the first: its run would have published an index without them and deleted them from halkyon.app. Each APK the published indexes (repo and archive) name now comes from the repository first unless the folder has it, its SHA-256 checked against the index's either way.
