The controller's other writer of the 16 KiB bucket of merges, the keeper of mesh-delivery's merge words,
called every put failure "not now". A word too large would be retried as the forge's merges were. It now
puts through kvlimit.Put: a value that does not fit is refused before it is put and returned as an answer
(the events consumer takes it, max-deliver 5 then a dead letter), and only another failure is retried.
It is the one write of the controller whose failure was retried as "not now" (searched: every Put,
Create and Update wrapped in ErrTryAgain).
Needs the group's mesh-sdk head (go/kvlimit, 7b02f63 or later).
Quick fix: none smaller. Thorough fix: every bucket write through kvlimit; this is the only one whose
refusal was retried, the others fail once and say so. No new test: kvlimit is tested in mesh-sdk, and an
integration test here would push the repository further over its budget (rules-are-weighed).
Research 072 piece: 03-domains (Control shrinks): the merge words stay the controller's only until the
registration of a moved module leaves it.
