- The roof is rescanned only in area columns that changed since the last scan: a quiet Huge world goes from 4.60 to 1.88 ms per scan (every 20 ticks). - The heat pass skips react() for solids and powders below their first reaction threshold: Huge world digging 2.54 -> 2.34 ms/tick, quiet 1.39 -> 1.18. - Every suite's output is identical apart from timing lines; seeds make the same worlds. - test/t_sim_optimizations.js checks the dirty roof against a full scan and the heat loop against the reference loop byte for byte.
