dtourolleandClaude Opus 5 3330f350a4 Move the timeline marker from the window the grid already read ...

The last of the per-scroll queries, and the strangest of them: this one got
slower the further down the library you had scrolled.

The marker has to follow every scroll event or it advances in jerks while the
photographs beside it move smoothly — that part is right and stays. What was
wrong is that each event asked the catalog `LIMIT 1 OFFSET n`, and that is not
a seek: SQLite reaches row `n` by producing and discarding the `n` rows before
it. 0.02 ms near the top of the library, 0.7 ms at twenty thousand, per row
crossed, on the thread drawing the frame. A flick therefore got choppier the
longer it went on.

The window the grid has already read holds the answer, and since the loaded
window now covers the whole view, the row is nearly always in it. So this is a
vector index at the position the ordinal has in the window, and the query
survives only as the fallback for a row outside it — briefly, after a scrub or
a keyboard jump, before the load lands.

The fallback is also the less correct of the two, which is worth recording
rather than quietly keeping: it counts in a dated-only ordering while the
argument is a grid row, so the two disagree wherever undated frames sit in
between. It is kept because a marker about to be corrected is not worth a
second index, and because being wrong there is what it always did. The window
path has no such disagreement — it reads the very cell the row belongs to.
