fix(story-mode): "Done, with a note" not for how things were before, nor "still open" as a verb

A sample of the 308 real pages titled "Done, with a note" read as open
work in about nine of ten. The rest were history ("Before, that early
idle could end a wait…", "used to") or "still open" as a verb ("JSON
files still open the live log viewer, as intended"). Neither counts as
something not done any more, and a history sentence is no open problem
either.
