The command refused every real invocation. Go's flag package stops parsing at the first non-flag argument, so with the positionals first — the order that reads correctly — `--from -` stayed among them and the count check rejected it. The host's own parser carries a note about this exact fault, and the version it describes is worse: there a flag somebody passed was silently ignored and the command succeeded anyway. This one at least refused. The tests did not catch it because every case in them was a rejection. The command was broken in the only way that matters — it refused what it is for — and the suite was green. The lab found it at the first call. Two tests now: the helper, and the command itself with a --from naming a file that is not there, so the complaint must be about the file rather than about usage. The second exists because injecting against the first stayed silent: testing the helper alone left the command free to ignore it entirely.
