-- The per-node resolver's seat is gone (novox/hq ADR 0220, retiring what ADR 0194 decided).
--
-- ADR 0194 retired `node-dns-resolver` when the mesh moved to one resolver, and kept its row while a
-- machine still held it: removing a seat that is claimed makes the claiming machine unresolvable. On
-- the mesh this was written for, nothing has held it since every node's resolver moved to the mesh's
-- one, and no module in the catalogue claims it, so the row goes.
--
-- **The compiled defaults no longer carry it, and that alone would not remove it.** Seeding adds a
-- seat a release ships and never takes one away (ADR 0122: the table is the live set, and an
-- operator's row is left as it is), so a seat the mesh stops defining stays in the table until
-- something deletes it — this.
--
-- A holding on record goes with it by cascade; there is none. No alias is kept: nothing was renamed,
-- and a manifest still claiming the old name should be refused at registration, naming it, rather
-- than resolve to anything.
