A boundary-by-boundary diagnostic for a valid PointCloud2 that never produces Nav2 occupied cells, with a stationary target test and evidence worksheet.

A boundary-by-boundary diagnostic for a valid PointCloud2 that never produces Nav2 occupied cells, with a stationary target test and evidence worksheet.

A source-to-grid diagnostic and measured target-height matrix for overhanging obstacles visible in LiDAR but missing from a Nav2 costmap.

A layered diagnostic for stale LiDAR obstacles in Nav2, connecting fresh observations and clearing-ray geometry to a reproducible place-and-remove test.
