VoxelForge/Standalone/Research/WorldAssemblerM3/Linux140/l140-fi-around-tunnels.patch
T
Fr0zkaandClaude Opus 5.5 4f93f3fffb research: Floating Islands planned around fixed tunnels (L140, 0/16; kept as patch) 
Native FI binds and its own route/clearance/mouth-support checks pass on seeds 0 and 10, but 14/16 seeds have no
island arrangement that clears the fixed passage tubes and reaches both mouth heights; seed 10 has one composed
collision; ripple 6-7 cm vs the 3.5 cm limit on both upper passages. Third failure of the 'islands adapt to fixed
tunnels' premise (L133 x2, L140).
