Eric clicked accept-overhang on two boxes in a Kallax cube and got an
"overhang ✓" pill with no lane behind it. The cube's flat pile claims
11.7 of 13.25 inches of width, leaving 1.55 inches of standing lane —
acknowledging waives depth and height, never width, so nothing changed.
That opening is overfull, not overhung, and the button was a placebo.
The sheet now probes before offering: a laneless resident gets the
accept button only when acknowledging would actually land it a lane;
otherwise it's marked "no room" with the honest tooltip. Acknowledged
boxes that DID land show "▮ standing, proud" (their lane isn't
flippable — proud of the shelf is the whole point), plus the
retractable "overhang ✓". Verified against the live wall: the three
Etherfields monoliths on the tower's big row read standing-proud, the
squeezed cube residents read no-room, zero page errors.
