Can cell 4970001547 see its neighbour?

A curvature-corrected line-of-sight from this Thane cell to its nearest neighbour, traced over the 30 m DEM and building-height surface. The physics is field-determined; outside the raster footprint, or across DEM nodata, the engine refuses rather than ever assuming "visible".

The sight-line from cell 4970001547 to neighbour cell 4970001546 is obstructed over the 30 m elevation + above-ground building-height surface, with Earth-curvature and atmospheric refraction applied. This is a field-determined geometric fact, not a model estimate.

Scope: the live MH-36 cube. Line-of-sight is computed over the served 30 m DEM + AGBH surface with curvature + refraction; it is never interpolated past the raster footprint.
