/**
 * anchorFor() validates --ref, but so does main() before it: main() skips a
 * selected agent that already carries an attestation in data/attestations.json
 * before it ever calls anchorFor(), so a shape check that lived only inside
 * anchorFor() would let a malformed --ref sail through for any agent already
 * attested. These tests spawn the real CLI (not just the exported function)
 * so that regression stays caught regardless of which validation path it was
 * fixed in. Every run here is --dry-run: nothing is signed, no wallet is
 * loaded, and data/attestations.json is only ever read, never written.
