A covenant-held name's certificate is at the covenant's address, so the
gateway's holdings - which looked for certificates among a wallet's coins -
never listed it under anyone. It is now listed under the key its verified
state names, with its expiry and where it is in its life.
covenant-registrar.js is one function per thing an owner does with the
built-in wallet: move a name into the covenant, renew, publish records,
transfer, release. Each announces the new state, and refuses a stale view
of the name rather than guess where the certificate went. Tested against a
simulated chain: every transaction is run through the VM, applied, and
read back through the resolver.
The name index fetched its transactions one at a time, which had grown to
most of half a minute before a registration could be quoted; it now
fetches eight at a time.
