Validate the customer.id parsed from bootstrap.json to a DNS-safe label (reject spaces/slashes/leading-dash) and pass it via a quoted array, so a malformed or hostile id can't smuggle extra docker flags (e.g. --privileged) into the controller's de-privileged `docker run`. Empty/invalid → no --hostname. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
