About Check Pvs
Check PVS (Potentially Visible Set) visibility between two world positions in a BSP map. Returns whether the BSP considers the two points mutually visible — i.e. whether the engine would have sent entity updates between them. Also returns the PVS cluster indices for both points. PVS is a conservative over-approximation: visible=true means updates were sent, not guaranteed line-of-sight. Accepts a bare map name, 'maps/.bsp', or a direct path — see get_bsp_info for lookup rules.
