**Not acceptable.** In revision B, the pallet spans world Y = 1.40 ± 0.50, or **0.90 to 1.90**, overlapping the aisle (0 to 1.20) by **0.30**.

This conclusion uses the current revision B geometry. Revision A’s `aisle_clear = true` applies to the earlier placement and does not establish clearance for revision B, which has not yet been checked.
