Passage visits -78..-89% near-ready; composer worker time back to baseline on Tunnel Network; v239 is 2-4% faster than v236 in 7/8 cells but still +4.3..+13.3% near-ready vs assembler/world. Surface World composer time equals baseline yet near-ready is +4-6%: unexplained. 16/16 seeds, fast tier, Clang/GCC green.
