- Removed temp from Cell (13→9 bytes), added temps/pressure/gas_type/gas_density/light arrays to Chunk - Layer access via grid.get_temp()/set_temp()/get_gas()/set_gas()/get_pressure()/set_pressure()/get_light()/set_light() - cells_swap swaps all layers, set_material sets default_temp - heat_transfer refactored to direct array access on temps[] (no Cell copy) - CA rules refactored: cell.temp → grid.get_temp()/set_temp() - gas_step: gas flow (rise, spread), fire produces CO2+smoke, steam condenses to water, acid+organic→poison gas - pressure_step: pressure equalization for connected non-solid cells - light_step: world-space persistent lighting, updated every 10 ticks, ray-cast line-of-sight - Gas damage: poison gas damages entities, CO2 suffocates, applied before ca.step() - Multi-section chunk serialization (VWM1 magic + cells + temps + gas + pressure + light) - Old 12-byte chunk format auto-detected for backward compat - AI spectrum: new gas + pressure spectrums, light spectrum uses world-space fallback - Protocol: gas/pressure spectrum commands - pre_dirty mechanism: layer steps process pre-clear dirty rects for cross-cell diffusion - 14 new multilayer tests, all 185 tests + 14 scenarios pass - Benchmark: 85.9 FPS (graphics surface, was 128 pre-layers — 33% regression from 4 new layer steps)
