`#` held the high quotient on the return stack across its second UM/MOD, which was the deepest point of pictured output once C! was made call-free. It now rotates it under the division on the data stack (-ROT in line: SWAP push SWAP pop). Headroom, return entries: <# #S #> 2 -> 3, the signed picture 1 -> 2. Data room is unchanged. Same 4716 checks per width at 32- and 64-bit cells, optimised and ASan+UBSan (`make test`, `make sanitize`); the headroom checks now require the new figures. Test results on the amd64 host only. This is a development check, not acceptance (JUSTIFICATION.md section 16). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
