Merge of `gh/main` at 0947fd0. No conflicts: improvise-5jm5's `Aggregation`
enum reaches `ui/project.rs` at three lines (one import, two call sites) and
none of them is one this branch touches. Re-checked here rather than trusted,
since `project.rs` was being reworked for improvise-mcq4 after that check was
made; the mcq4 code is in `ui/app.rs` and does not overlap.
Two things beyond the merge.
**The benchmark fixture now says not to simplify it.** `prune_empty` is the
only thing that makes the frame fingerprint walk cells, so a geometry case with
it off measures the cheap half — 17–176µs against the real 5.75ms — and reports
that as the cost. It is the reason improvise-mcq4 was nearly missed, and it is
the first thing a later reader would "tidy". The comment names the file that
carries the argument.
**`context/code/command.md` carries the fixed numbers and, more usefully, the
fact that the obvious fix bought nothing.** Narrowing the fingerprint from every
view to the active one was the ticket's first option and my own suggestion, and
it moved 12.41ms to 12.56ms, because a second view is typically fresh with
everything on `Axis::None` and costs nothing to build. That is written down,
because the next person to look at this will have the same idea.
Gate note: `--check-evidence` does not run the comment-run cap — they are two
modes of one script. Both are run separately here.
