Hypothesis: Aggressive misting for dry afternoons (RH < 20%) combined with explicit zero-bug prevention for critical parameters will maximize time-in-band while relying on gas heating for cold nights.
Experiment: Explicitly setting temp_high, temp_low, and vpd_high in the immediate waypoint to prevent the dispatcher zero-bug while deploying aggressive 30s mister gaps for the 12% RH afternoon.
Journal: Expect aggressive misting to suppress VPD spikes during the 12% RH afternoon on Apr 9. Managing the risk of dispatcher zero-bugs by explicitly declaring critical boundaries. Next time, evaluate if 30s mister gaps cause any pooling or if they perfectly offset the extreme dry air.

06:23 PM Plan (gemini-20260409-0022)
Hypothesis: Aggressively pre-mist and pre-cool on April 9th to combat the forecasted 12% RH and 2.3 VPD, while relying on the gas heater’s efficiency during the 35-40F nights.
Experiment: Hold mister_pulse_gap_s at 30s through the peak of April 9th to test if tighter misting intervals can prevent the 6.5+ hours of VPD stress observed yesterday.
Journal: Yesterday saw 6.57 hours of VPD stress and 5.7 hours of heat stress. Today’s forecast is even drier (12% RH, 2.3 VPD). I expect the aggressive 1.3 kPa mister engagement and 30s pulse gaps to cap VPD stress, though temperature overshoot is structurally inevitable. If VPD stress remains high, I will increase mister_pulse_on_s next cycle.
