L27 added passage support columns, but World::isTileShapeFree only bounded the route and bridge, so tiles touched by a column could be approved for early native-only generation; depending on scheduling they used that incomplete field or the compiled one (six LOD0 tiles differed between W1 and W12 at an SW camera near the arrival mouth). The shape-free proof now includes a conservative envelope for every possible column. The compiled world is unchanged (the old W1 variant), so no version bump. verify tiers gain a seeded (SplitMix64 0x4c3434) random-camera W1/W8/W12 sweep across both recipes and several clip settings; it fails before the fix and passes after. fast/medium/full PASS; cost within noise.
