The perceptual check found seven items; item 1 passes. Chaos d8=8 fired
the FIRST override at the new rate, on the second roll, and drew S --
which is what the structural derivation said, so it changed nothing.
That is one half of window 2's retirement condition (retire if an
override changes nothing twice running).
The maintainer's design instruction is adopted directly: a legal drop
target should change its EXISTING border to dashed rather than draw a
new outline. That explains the hidden top/left edges (an outline on an
SVG <g> is clipped by the viewport) and the oversized seat highlight.
The ghost is a textContent copy, which is why the linebreak collapses and
it reads as a second card, and why showing the explanation destroys the
label -- one cause, two reports.
T03 carries an explicit instruction not to fix a message that already
works: the 'nothing droppable' path may simply be unreachable because
almost every part of the page is a card. Reproduce before changing.
T05 records that 0 scores and no winner is very likely the stand-in
dataset rather than a scoring bug, now that GROUND-WP-0002 T01 has ruled
the edition data authoritative. The import is its own pass.
