Hypothesis

Testing: Test whether earlier, explicitly band-coupled dry-ramp support after a guarded midnight/pre-dawn posture reduces VPD-high guardrail holds versus the failed SUNSET unwind while keeping dp-risk at 0h. Expected outcome: For the 00:20-08:30 window: dp_risk_hours 0, no added VPD-low beyond a small pre-dawn carryover, and cold stress under 1h. For Sunday daylight: fewer VPD-high moisture guardrail holds than iris-20260523-2017, VPD-high materially below Saturday’s alert burden, and no conservative evening unwind until observed VPD recovery.

Safe humid midnight snapshot after a poor Saturday: greenhouse 64.0F, VPD 0.52, RH 74%, dew margin 8.3F, IDLE, heat1 active. Pre-dawn outdoor VPD stays moderate around 0.5-0.8 kPa, then Sunday ramps hard by 09:00-13:00 to RH 13-19%, VPD 2.6-3.4 kPa, and solar around 750-900 W/m2 before cloudy but still dry late afternoon/evening.

Expected stress windows

vpd_lowlow · 2026-05-24T00:20:00-06:00 to 2026-05-24T08:30:00-06:00

Moderate overnight suppression: engage 1.6 then 1.45, all 1.9 then 1.75, 45-50s gaps, longer delays, fog_escalation 0.35-0.45, vpd_hysteresis 0.5, and 120s sealed cap while dew margin stays safe.

vpd_highhigh · 2026-05-24T09:00:00-06:00 to 2026-05-24T21:30:00-06:00

Before live dry stress can force guardrail holds, transition to band-coupled moisture: engage 0.85-0.9, all 1.05-1.1, 30/60s delays, 20s gaps, fog_escalation 0.15 in the fog window, min_fog_off 45, capped sealed residence 150-180s, and no conservative unwind until evening VPD actually recovers.

heatmedium · 2026-05-24T11:00:00-06:00 to 2026-05-24T18:30:00-06:00

Accept some physics-limited heat pressure but keep d_cool_stage_2 2.0 and temp_hysteresis 1.3 while short sealed caps let VENTILATE preempt and moisture assist protects VPD.

vpd_highhigh · 2026-05-25T08:00:00-06:00 to 2026-05-25T18:30:00-06:00

Missed-SUNRISE fallback returns to band-coupled moisture for Monday’s even hotter/drier ramp rather than carrying overnight conservative thresholds.

Parameter rationale

mister_engage_kpa1.05 → 0.85; Sunday forecast reaches RH 13-18% and VPD 2.7-3.4 kPa after 10:00; previous SUNSET plan had 64 guardrail events when unwind values rose too early.

Avoid VPD-high guardrail holds during the dry ramp and reduce VPD-high stress relative to Saturday.

mister_all_kpa1.25 → 1.05; Active vpd_high is 0.8 kPa and retrieved lessons say all-zone escalation should stay near max(1.0,vpd_high+0.25) in live hot-dry VENTILATE.

Permit all-zone assist during severe dry ventilation instead of waiting above the crop band.

fog_escalation_kpa0.3 → 0.15; Dry peak overlaps 07:00-17:00 fog window; fog is 7x more effective and guardrail-aware lessons call for 0.15-0.20 in hot/dry venting.

Catch stubborn VPD-high without extended sealed heat traps.

min_fog_off_s60.0 → 45.0; Hot/dry venting can clamp fog-off dwell to 45s and today’s forecast has VPD above 3 kPa with healthy dew margin expected by peak.

Permit effective fog cadence and avoid dispatcher rewrites.

mister_pulse_gap_s30.0 → 20.0; RH falls to low teens through the afternoon; dry-day lessons call for 15-25s gaps under severe dry pressure.

Reduce humidity collapse between pulses during VENTILATE assist.

mister_engage_delay_s45.0 → 30.0; Recent VPD-high guardrail events show long delays and conservative thresholds are wrong during live VENTILATE dry stress.

Start physical pulses promptly once humidity demand exists.

mister_all_delay_s90.0 → 60.0; VPD climbs steeply between 09:00 and 12:00, so all-zone escalation should not wait 90-300s during the dry ramp.

Reduce time above the VPD band during the morning ramp.

temp_hysteresis1.5 → 1.3; Midday heat pressure is likely but not above the 85F structural extreme; tighter hysteresis helps reject heat while mist/fog protects VPD.

Improve temperature compliance during the dry ramp without changing crop bands.
