- World > Add > Invisible Wall: a 2 x 2.5 m box (Object role) standing on the floor across the view. Frame Home never draws it; it stops you and is never stood on. - Meta's invisible walls (a solid collider with nothing drawn, 2 m or taller: Cascadia's, Space Station's, Desert Terrace's, Haven's) load as invisible walls instead of surfaces, so the play space they bound holds. - Walk grid: a drawn floor's edge exemption no longer applies within a body's radius of a wall, so a wall through a drawn floor takes that floor away. tools/walktest/wallcheck: walls at every angle never have walkable area inside. - New items land on the home's own surfaces when the spot is beyond the walkable area. - The Planet (World > Add > Planet, Planet Pull) is gone; older files' planet zones still load. - ImGui menus: a safe triangle from where the pointer was on the item to the whole submenu; crossing other items on the way neither opens them nor closes it (resting 0.3 s still does). - Self-test: invisible wall placed, walked into (with and without the area), through a drawn floor, undone (98/98).
