- accepted building transform
- Three independent W-6 interior/structural spans now diagnostically agree with the frozen transform within source-pick allowances; independent repicking, face classification and local distortion checks remain outstanding.
- The control intersections carry source-picking uncertainty and the photograph may retain local paper or lens distortion.
- A source-space boundary is not automatically an outside face, clear face, shaft wall, slab edge or opening.
- Only explicitly classified analytical locators below may use this transform; wholesale plan extrusion is prohibited.
- Extruding any transformed locator into physical walls, shafts, stairs or rooms.
- Treating control-fit zero as proof of accuracy.
- Using the coarse Elevator 3 or stair locator boundaries as clear or outside faces.
- Replacing unresolved wall, slab, opening or construction thicknesses with defaults.
