wall-framing-takeoff counted drywall sheets from wall areas, but a butt joint that lands between studs has nothing to screw to. The engine learned to snap wall end joints to studs on 2026-10-26 (CLI only). The page now has a "Wall end joints" control with three choices: not placed (sheet count only), snapped to studs, or placed without snapping, which reports how many joints land off framing.
A 20 ft wall with 10 ft sheets puts its joint between studs unless snapped; the hand-count test pins that case. What is still unchecked: a real hang, and ceiling joints on joists. Estimates only, not engineering or building-code advice.
