// **The store after release 6's migrations is still one today's controller (C5) can read** (issue 1945, review round 1): the
// revert path puts C5 back, either by the witness or by the operator's want, and it reads the columns of the node row that
// recorded a send (sent, sent_at, sent_bus_users, sent_builds, sent_epoch, sent_summary, sent_generation, sent_provisioning)
// and the tables of the plans' machinery (build_gate, declaration_send, assignment_generation, duration). Release 6 reads
// none of them any more and drops none: they go in a later milestone, once C5 has left the controller's five newest
// fingerprints. Each query below is one C5 ran.
