04's ruling makes the drag the pointer's delete gesture: the shown
trash column accepts live same-board card drags, the shadow pinned
topmost — honest, since the trash sorts by deleted newest-first — and
release tombstones through the same write path as Backspace, extracted
so the two gestures cannot drift. DropTarget grew a container case for
the quasi-lane (it has no lane id by construction); lane drags,
cross-board arrivals, option-copies (re-checked at release, the one
input that can flip without a callback), trashed-side payloads, hidden
trash, and the read-only lock all refuse — and a refusal falls through
to the strip retarget, never cancelling the drag. The settle draws the
tombstoned rows in the trash under the cards' own GUIDs, so the echo is
an invisible content swap and nothing winks out for a round trip.
Selection needs no surgery: the reload's resolve rule ejects tombstoned
members as the vanish it is, pinned by a test contrasting both gestures.
