Generate a minimal, correct client in the language/executor the user names: it must (1) compute a stable hardware id, (2) POST /api/v1/key/check with header X-Project-Key and JSON body { key, hwid, nonce } where nonce is fresh per call, (3) verify the returned base64 Ed25519 signature over sha256(nonce + '|' + hwid + '|' + expiresAtUnix + '|' + project_id) using the project's public signing key (expiresAtUnix is seconds since epoch, 0 when expires_at is null; nonce_echo must match), and (4) only then run the script body. On any failure, exit without running the script. Output just the code and a 3-line prerequisite list (endpoint, project key, public key).";
