Return a grant not written and retry the take-in under a condition; drop the plans' events; grant bucket-deleted, restic's backup word and the operator's hand path (issue 1945; the review's D1, F1, H1 and its notes)

With no send left nothing else writes a missed grant, so the take-in of a done key returns it and tries again every
half minute under an urgent condition until it is written. plan-moved and sent go with the plans. The controller's
first-start deletions are said on a granted subject, a node hears only its backup holder, and the operator's account
writes the hand path, an object replaced included (ADR 0539 clauses 2, 7, 10 and 13).
