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

Hypothesis

Testing: Test a clean two-phase handoff: conservative humid pre-dawn suppression followed by explicit guardrail-clean band-coupled moisture before the high-solar dry ramp; success means dp-risk 0h, daytime VPD-high under 3h, fewer guardrail holds than iris-20260527-0537, and cost under USD 5 unless compliance needs water/fog. Expected outcome: By next midnight: dew-risk 0h, minimum dew margin above 5F, both-axis compliance at or above 70%, VPD-high under 3h despite 2+ kPa outdoor VPD, heat stress under 4h, no new VPD-high moisture guardrail holds from conservative moisture requests, and total cost near or below USD 5 unless fog/water are needed for compliance.

Humid safe midnight with 6.2F dew margin. Pre-dawn is saturated, then Thursday dries sharply with high solar and 2+ kPa outdoor VPD. Forecast has missed clouds/solar recently, so ramp is live-confirmed but not conservative once VPD nears band.

Expected stress windows

vpd_lowmedium · 2026-05-28T00:30:00-06:00 to 2026-05-28T09:30:00-06:00

Suppress wet/fog with high dew floor, long gaps, and resource-conservative humid posture while keeping ventilation/dehum available only when safe.

vpd_highhigh · 2026-05-28T11:00:00-06:00 to 2026-05-28T19:30:00-06:00

Open band-coupled wet assist before peak: mister engage near vpd_high+0.05, all-zone near +0.25, fog escalation 0.15-0.20, stronger cooling lead.

vpd_lowmedium · 2026-05-28T20:00:00-06:00 to 2026-05-29T08:30:00-06:00

After observed recovery, unwind wet/fog into humid night with conservative dew floor and high resource sensitivity.

vpd_highhigh · 2026-05-29T11:00:00-06:00 to 2026-05-29T19:00:00-06:00

Missed-SUNRISE fallback keeps Friday severe dry ramp fully band-coupled rather than using humid-night thresholds.

Parameter rationale

mister_engage_kpa1.17 → 0.85; Thursday VPD rises above band after 11:00 and lessons 131/134/125 say saturated-dawn dry ramps need band-coupled moisture once live VPD nears high edge.

Reduce daytime VPD-high without creating new guardrail holds.

mister_all_kpa1.42 → 1.05; Forecast reaches 2.0-2.43 kPa VPD from 14:00-18:00 with high solar, and east/center crops need distributed assist.

Enable all-zone rotation near vpd_high+0.25 during the dry ramp.

fog_escalation_kpa0.5 → 0.15; Dry ramp overlaps the fog window and dew margin should widen after warming; fog is 7x misters and should not wait far above band.

Allow vent-fog assist for stubborn VPD-high while firmware RH/temp/dew gates protect safety.

mister_pulse_gap_s60.0 → 20.0; Hot/dry VENTILATE pressure is forecast at peak and recent guardrails clamp long gaps during live VPD-high.

Hold VPD closer to band between pulses during peak stress.

direct_wet_stress_min_dew_margin_f14.0 → 8.0; Peak dry ramp should have healthy dew margin, but pre-dawn and night remain humid.

Permit daytime recovery while blocking wetting in marginal dawn/night dew conditions.

cool_stage2_over_high_f2.07 → 0.6; Solar near 870 W/m2 and lesson 104 call for earlier cooling readiness before temp crosses high edge.

Reduce heat/VPD coupling during high-solar ventilation.

mister_water_budget_gal110.0 → 250.0; Thursday dry ramp and Friday fallback need enough water headroom; cost remains secondary while VPD is out of band.

Avoid water budget becoming a hidden VPD recovery cap.
