--boot --capture= used to write no file: _finish_boot() was reachable only from
the overlay-quit branch, and the boot quit first because that branch fires when
_overlay_spec.is_empty(), which it is the instant the overlay is raised. Fixed
earlier this session by the _overlay_quit_at guard -- and I never went back to
check what the fix made possible. The P3/P7 artifact has been available for hours
and unused.
The boot running unattended and photographing its own end state: RMSE 12.80,
0.00% differing against live-title-press-a.png. The residual is the known capture
gamma floor.
More useful: verify-capture reaches this frame by a shortcut (--screen=title
--overlay=press_start --time=3.95) rather than by booting, and that shortcut has
been trusted since it was written and never tested against what it stands in for.
It is faithful -- 12.83 / 0.00% against the boot path's 12.80 / 0.00%, agreeing to
0.03 RMSE.
Does not show the intervening sequence is right: it is one frame, the last one.
