A waypoint-graph builder that prunes only isolated nodes still ships fully-connected but walled-off pockets, because graph kept is not graph reachable. In one build, sealed arena corners stranded 27 of 524 nodes as three internal pockets, and about 5% of a max crowd spawned where it could never leave. Filter destination and spawn candidates by connected component, using a flood fill from a known-good root, not by per-node validity checks.
