review::submit counted only the writes still waiting, so a write staged
after an accepted one got that one's id and was lost: never listed, never
acceptable. It now counts every Waiting line of the day. On a scratch tree
with task 16's line applied, both new tests fail and then pass, the old code
and a count of every line are both caught, and the gate passes (938 there;
941 after task 18).
