02 rules the trashed side has exactly one definition: the set with
trash rows — a card carrying its own deleted: under a tombstoned lane
is in neither universe, so an anchor or selection can never survive on
an item that renders nowhere. The membership rule now lives once, in
Liveness.walk, and ItemReferenceSet.idUniverse, TrashModel.entries,
paths, and emptyTrashTargets all derive from it — the old
lane-OR-card logic that admitted subsumed cards to the trashed side is
gone, and the two universes deliberately no longer partition the
board. Put Back, Delete Immediately, and Empty Trash outcomes are
unchanged: a tombstoned lane still moves and purges whole, its nested
tombstones with it.
