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

Hypothesis

Testing: Test whether explicitly guardrail-compatible ClimateIntent values after a 598-event guardrail day reduce held-by-guardrail wet-assist rows while preserving dew safety on another severe hot-dry ramp. Expected outcome: By next midnight, dew-risk hours remain 0, VPD-low stress remains 0, VPD-high stress remains the dominant unavoidable miss but daytime VPD severity improves versus the 2026-07-15 SUNRISE window, and held-by-guardrail wet-assist rows decline from the prior 513-event evaluation.

severe repeated July hot-dry sequence; Thursday near 93-96F with RH below 20% and solar near 900 W/m2, followed by hotter Friday/Saturday; forecast VPD is positively biased but corrected VPD remains far above the crop corridor

Expected stress windows

vpd_highhigh · 2026-07-16T08:00:00-06:00 to 2026-07-16T22:00:00-06:00

band-coupled wet assist: engage near vpd_high+0.05, all-zone near +0.20 to +0.25, daylight fog escalation near 0.15, and keep evening recovery available while dew margin stays above 8F

heathigh · 2026-07-16T11:00:00-06:00 to 2026-07-16T21:00:00-06:00

45-60 min thermal lead, solar pre-cool, all-fans VENTILATE with wet/fog assist; accept physical cooling limits rather than target-hugging

vpd_highhigh · 2026-07-17T08:00:00-06:00 to 2026-07-17T22:00:00-06:00

repeat compliance-first wet/fog assist for Friday, with no resource taper until observed VPD recovers

heathigh · 2026-07-18T11:00:00-06:00 to 2026-07-18T22:00:00-06:00

strongest wet-assist posture for forecast 100F+ Saturday while treating peak heat as structural and maintaining dew safety

Parameter rationale

mister_engage_kpa0.82 → 1.27; current vpd_high is about 1.22 and east is already dry-edge at 1.36 kPa before a 900 W/m2 / RH <20% dry ramp

keep S1 wet assist available near vpd_high+0.05 without relying on dispatcher correction

mister_all_kpa1.02 → 1.44; zone VPD spread remains >0.5 kPa and yesterday had 14.21h VPD-high stress

make all-zone rotation available near vpd_high+0.20 to +0.25 during hot-dry ventilation

fog_escalation_kpa0.2 → 0.15; daylight VENTILATE overlaps the 07:00-17:00 fog window and fog has the best recent VPD-error response

reduce VPD-high severity during safe daylight windows while dew margin stays above 8F

mister_pulse_gap_s30.0 → 22.0; forecast solar reaches ~900 W/m2 and corrected VPD remains above band from midmorning into evening

increase effective wet duty during peak dry ventilation without changing crop bands

mister_water_budget_gal260.0 → 300.0; water was high yesterday but VPD compliance was still only 35.6%, so budget clipping would worsen safe out-of-band stress

avoid budget-limited VPD recovery during the severe ramp while still tapering only after measured recovery
