Real rsync runs over fake ssh and sshpass scripts that execute the remote side locally, covering --link-dest, removal, key file, password and --remote-sudo without a server.
Configure ruff in pyproject.toml and apply its fixes: modern annotations
(X | None, builtin generics, collections.abc), sorted imports, explicit
stacklevel in test warnings.
Test how command line and config values are combined, the exit codes for an incomplete SSH setup and a bad config, and the user detection under sudo/doas (simulated by patching geteuid and the environment).
Configure pytest in pyproject.toml to import the repo copy, add a conftest that keeps tests out of the journal and desktop notifications, and test reading the config file and expanding paths.
