Reflection

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

Hypothesis

Testing: Guardrail-clean midnight reset: keep humid pre-dawn suppressed, then request band-coupled daytime moisture directly during the dry ramp; success is >70% Wednesday both-axis compliance, VPD-high under 3h, dp-risk 0h, VPD-low under 1h before sunset, and materially fewer VPD-high moisture guardrail holds than iris-20260526-2020. Expected outcome: By Wednesday sunset: no dew-risk hours, VPD-low under 1h before the humid night, VPD-high below 3h despite the overcast dry ramp, cost under USD 5 unless fog/cooling is required for compliance, and reduced guardrail holds versus the prior sunset plan.
