No pure-O2 aeration. Splash aeration only: wort ran in through the open top of the fermenter (lid off) so it splashed down off the CFC hose (Chris's standard method, judged plenty). Planned 12h second aeration dropped given the healthy fast start. |

Hold ~2 days at 20C; gate the crash on a FORCED diacetyl test Sat 6/27 (heat sealed sample ~150F 15-20min, smell/taste vs unheated control) -> slow cold crash if clean, else hold + retest.
