-- Partial unique index: only ONE verified binding per hostname. The
-- hostname-unique constraint above prevents duplicates across all
-- statuses; this partial is redundant as written (unique already
-- covers it), kept here as an invariant-docs comment. If we ever drop
-- the global unique (e.g. to allow one user to re-add a domain another
-- user abandoned), this becomes the load-bearing constraint.
