Reflection

Daily Summary So Far — this cycle will be validated at the next planning cycle.

Hypothesis

Testing: Use measured VPD to switch from drying to band-coupled assist at the high edge during the 09:00-10:00 ramp. Expected outcome: Keep overnight VPD-low and dew-risk at 0h; reduce controller-attributable VPD-high exposure during 10:00-15:00 without chasing in-band target deviation.
