Reflection

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

Hypothesis

Testing: Test a live-edge bridge followed by a measured pre-dawn taper and early dry-ramp re-opening without changing crop-owned bands. Expected outcome: Across the covered window, keep dew-risk at 0h and VPD-low at 0h, hold VPD-high stress below 1.5h, and improve moisture availability without overnight over-wetting.
