The automation suite's DNS test compared the published zone with one
copied from upstream v0.16.22. Its _ua-auto-config record carries a
SHA-256 of the account-configuration (PACC) document, and that document
names the provider as the brand, which the rebrand changed. The digest
the server publishes is right; the expected zone still held upstream's.
With the new digest the whole automation suite passes: ACME (including
the not-due reschedule check), DKIM, DNS and RFC 2136. It had been
failing at this point on main since the rebrand.
