User report at the Facility Hub double door (Setup 0x02000C9D): embed
into the visual panel from one side, phantom wall on the other. Dat
inspection (Issue175HubDoorPoseInspectionTests, kept as the evidence
fixture) confirms the mechanism: the Setup's Default PLACEMENT frames
pose the two panels AJAR (yaw -150/-30, origin (+-0.88, -0.44, 1.37))
while the rendered door poses them CLOSED from the wire-supplied
motion table via the sequencer. ShadowShapeBuilder reads placement
frames, so the 1.66x0.29x2.95 m physics slabs register at the ajar
pose — displaced behind the visual door. Retail tests each part's
LIVE pose (closed == motion-table default; the open swing is ETHEREAL,
#150). Fix shape filed: BSP shadow shapes for sequencer-bearing
entities must use the sequencer's part transforms, placement frames
only as the no-animation fallback. Holtburg's single door never
surfaced this because its placement pose ~= closed pose.
