A unit found running and enabled that a declaration held stopped and disabled stayed stopped and
disabled when the declaration went: ADR 0118 never starts a unit on the way out. Unassigning the zfs
module would so have left the home server's pool with no scrub schedule at all, said nowhere.

The host now records what it declared for a service (Declared, beside Found). On removal, a unit found
running and declared stopped is started again, and one found enabled and declared disabled is enabled
again, each read back; the report says restored, and the plan says it first. A record from before the
field starts nothing.
