Hypothesis

Testing: Midnight reset: keep wet/fog surface guardrail-compatible during a humid dawn and Thursday dry pockets, then stage aggressive but bounded wet/fog assist ahead of Friday/Saturday severe heat/VPD without chasing in-corridor target lines. Expected outcome: By Thursday sunrise: dp_margin_min_f stays >=7F and no dp-risk while VPD-low stress remains minimal. During Thursday dry pockets: reduce VPD-high severity without all-day water spend. Friday/Saturday: accept physics-limited heat but keep VPD assist available near the high edge with fewer guardrail-held wet-assist requests than iris-20260722-0551.

Thursday starts warm and humid with VPD-low/disease risk limited by a 10.3F dew margin, then has short dry pockets near midday/evening. Friday is severe hot-dry near 98F and 17% RH with VPD above 5 kPa; Saturday may reach 102F with solar near 900 W/m2, a physics-limited heat day.

Expected stress windows

vpd_lowmedium · 2026-07-23T00:15:00-06:00 to 2026-07-23T08:30:00-06:00

low mist duty and high dew-margin caution, while keeping band-coupled moisture available rather than requesting thresholds the guardrail must rewrite

vpd_highmedium · 2026-07-23T10:00:00-06:00 to 2026-07-23T14:00:00-06:00

moderate moisture near vpd_high+0.05 to +0.25 and fog escalation near 0.25 only when live dry stress confirms

vpd_highmedium · 2026-07-23T17:00:00-06:00 to 2026-07-23T20:30:00-06:00

aggressive guardrail-compatible wet/fog assist: engage near +0.05, all-zone near +0.20, fog escalation 0.15-0.18, full dry-stress budget

thermal lead, solar pre-cooling, all-fans cooling authority and evaporative assist; accept physics-limited peak heat

vpd_highhigh · 2026-07-25T08:00:00-06:00 to 2026-07-25T22:00:00-06:00

severe-day early wet/fog staging, full water budget, low resource sensitivity, and evening recovery while dew margin is safe

Parameter rationale

mister_engage_kpa0.82 → 1.27; active VPD high edge is about 1.22 kPa and recent high requested thresholds were repeatedly guardrailed down during near-edge dry stress

reduce guardrail-held wet-assist requests while keeping S1 mist available near vpd_high+0.05 whenever live dry stress appears

mister_all_kpa1.02 → 1.47; Thursday dry stress is brief but Friday/Saturday severe ramps exceed the VPD band by multiple kPa

allow all-zone rotation near vpd_high+0.25 during meaningful dry stress without forcing all-zone wetting during the humid pre-dawn

fog_escalation_kpa0.2 → 0.15; fog is 7x misters and Friday/Saturday daylight windows overlap VPD 5-6 kPa with healthy dew-margin gates expected

improve VPD-high severity during hot-dry VENTILATE while preserving firmware RH/dew/time gates

mister_water_budget_gal120.0 → 300.0; Wednesday conserved water at 148 gal total but scored only 59.6; Friday/Saturday are severe dry-stress days

avoid budget-limited VPD recovery during safe severe dry stress while using Thursday and overnight resource sensitivity for conservation

mister_pulse_gap_s30.0 → 30.0; recent guardrail materializes useful dry-stress gap near 30s and VENT_COOL_MIST_ASSIST improved VPD error in action priors

stay guardrail-compatible and avoid requesting long gaps that are then held during dry stress
