# Focused L4RA lane-overlap review · r476

The full-stream triangle diagnostic flagged `XB_CUSTOMGEMINI_1A_JM_00` against
a marked `RDP_LANEB_WD_AA_KT` triangle. A packaged host Chrome load placed
the player on recovered Route 475 near the candidate and framed the area from
above. The reported crossing is between an object triangle spanning roughly
`x=-412.4..-409.7, y=25.8..34.4, z=13.6..16.1` and a road triangle around
`x=-413.5..-400.2, y=30.3..38.7, z=13.8`. The view shows the marked curved
carriageway open beside the storefront/overhang; the detected crossing appears
at the structure edge rather than across the drivable lane.

This is a focused visual check of one flagged pair. It does not prove every
part of this placement, the remaining flagged groups, or all of L4RA are
correct. No source placement was changed. Chrome reported no page or console
errors.
