 * Renaming a code, and why it stops being allowed.
 *
 * The code was immutable, which made a typo permanent. It cannot be freely
 * mutable either: hosts.datacenter references it, every past order stores it as
 * plain text, and — the part no cascade reaches — each host's DNS name was
 * minted from it and registered at the provider, while the machine's own
 * hostname was set from it as it was built. Rename a code with hosts in it and
 * you get a datacenter called hel full of machines called fsn-01.
 *
 * Free while nothing references it, which is the case that matters: a typo
 * noticed shortly after creating one.
