The first two pieces of the installer, and deliberately the two that change nothing: what this machine is, and what would happen to it. The survey is the floor under every later choice -- a component can only offer a container shape if Docker answers for this user, or a host shape on a systemd machine with what that shape needs. It reports what it could not establish as unknown rather than guessing: an unprivileged probe of port 25 means "I may not bind this", not "something is listening", and reporting the first as the second is a lie an operator would act on. The plan is one list, and it will have three readers: --dry-run prints it, the interface will show it before anything happens, and apply will walk it. What you are shown is what runs. Tested on a fresh Debian 13 in qemu, which has neither Docker nor Node and so exercises every unavailable shape: 23 checks, including that nothing was created by any of it. The lab that machine runs in is in e2e/vm.
