Hypothesis

Testing: Test a split midnight reset: hard pre-dawn wet suppression followed by direct guardrail-clean band-coupled moisture before the 09:00 dry ramp, with evening recovery retained until observed VPD is below band. Expected outcome: Pre-dawn adds <1h VPD-low and 0h dew-risk; 09:00-22:00 dry ramp keeps VPD-high lower than Wednesday despite 90F/10% RH pressure, with fewer moisture-guardrail holds than the evaluated SUNRISE plan; cost may rise but should remain justified by stress reduction.

Safe midnight, VPD in band and dew margin 14.9F. Forecast dips humid pre-dawn, then severe hot-dry ramp: 89-91F, RH 10-12%, VPD 4+ kPa, solar near 800 W/m2.

Expected stress windows

vpd_lowmedium · 2026-06-04T03:00:00-06:00 to 2026-06-04T07:30:00-06:00

Suppress climate wetting with high dew floor, high resource sensitivity, and low mist duty while forecast VPD falls toward 0.29 kPa.

vpd_highhigh · 2026-06-04T09:00:00-06:00 to 2026-06-04T22:00:00-06:00

Guardrail-clean band-coupled moisture: engage near vpd_high+0.05, all-zone +0.20-0.25, fog 0.15-0.20, short gaps, and 300 gal budget when dew margin is safe.

heathigh · 2026-06-04T10:30:00-06:00 to 2026-06-04T19:30:00-06:00

Strong solar cooling lead and all-fan readiness; accept physically limited hot misses near 90F instead of extending sealed mist.

Parameter rationale

mister_engage_kpa1.25 → 1.23; Corrected VPD exceeds band by 09:00 and raw VPD reaches 4+ kPa midday with dew margin currently 14.9F.

Avoid conservative threshold guardrail traffic and keep S1 mist eligible during VPD-high VENTILATE.

mister_all_kpa1.44 → 1.43; Whole-house severe dry stress is forecast from late morning through evening.

Escalate all-zone rotation before VPD drifts far above the dispatcher band.

fog_escalation_kpa0.2 → 0.15; Dry stress overlaps the firmware 07:00-17:00 fog window while dew margin is safe.

Allow PR-A vent-fog assist during peak hot-dry VENTILATE without using fog during humid pre-dawn.

mister_pulse_gap_s41.25 → 20.0; Afternoon RH 10-12% and VPD 4+ kPa need higher evaporation duty after dawn suppression.

Increase VPD recovery duty without lengthening pulse-on first.

mister_water_budget_gal120.0 → 300.0; Today is a severe hot-dry ramp; water should not be the binding constraint during safe VPD-high recovery.

Prevent budget clipping in the highest-value moisture windows.

cool_stage2_over_high_f1.905 → 0.5; Forecast reaches 89-91F with solar near 800 W/m2 and recent heat/VPD stress paired in VENTILATE.

Restore near-edge fan2/all-fan readiness before the heat ramp.
