floor plans as typed planar partitions — every line carries its evidence
Five handheld phone pans → per-frame vanishing-point geometry → metric wall map. Solid = video-witnessed (weight = frames of support); hollow & dotted = estimated. Scale from the standard door-height prior; unfilmed rooms are absent, not guessed.
Tape-measured survey + city footprint anchors, compiled as one manifold planar partition — break a wall and it refuses to compile. Live manifold check in-page.
