reactor uses mg/L for concentrations, m³/d internally, °C, and 1/h for KLa — diverging from EVOLV's canonical Pa/m³/s/W/K. This was a real drift surfaced by the wiki audit; consensus is to keep it because the ASM kinetics literature universally uses these units and fighting that convention would obscure the math without improving correctness. Now documented as an explicit, approved exception with the conversion boundary spelled out. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
