// Tests for the authoritative-validator step's CLI resolution (#2163, Copilot).
//
// The point of the step is that it does NOT skip: `verify:skills` treats a
// missing CLI as a skip, and "skips when absent" plus "usually absent" adds up
// to "never runs", which is what made the acceptance criterion aspirational.
// So the branch that matters is the one that falls back to a pinned `npx`
// rather than giving up — and on a machine with a current CLI installed, that
// branch is never taken by an actual run.
