Reflection

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

Hypothesis

Expected outcome: Maintain >=8F dew margin and 0h overnight VPD-low/cold/dew-risk; unlock live-edge assist before noon and contain controller-attributable VPD-high stress despite physics-limited peak heat.
