The recorded verdict described the PREVIOUS configuration, so it is cleared and the
provider must be tested again before it can be activated. If the provider was
ACTIVE, it stops being so — the database refuses an ACTIVE row whose verdict was
measured against different configuration.

A chainPosition in the body is applied with insertion + renumber

semantics: the provider moves to that index of this scope's chain for its channel
and the others keep their relative order, renumbered contiguously from 0 in one
transaction. An ABSENT chainPosition leaves the position unchanged —
it is never defaulted to 0, which would silently promote an edited provider to
primary.
