P0 (verbatim-spatial-pipeline-port) Tasks 1+2. ConformanceDats loads the cottage-doorway cells from the real dats with their real ContainmentBsp; CottageDoorwayCharacterizationTests maps the Holtburg 0140..017F indoor neighborhood and pins the master-plan threshold building (origin 161.93,7.50,94.00): 0xA9B40170 vestibule (exit portal 0xFFFF + portal to 0171), 0xA9B40171 room. Grid math confirms the outdoor side is landcell 0xA9B40031 -> the 0031<->0170<->0171 ping-pong is verified real. Verified interior points recorded for the point_in_cell/find_cell_list goldens.
