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

Hypothesis

Testing: Replace incomplete/guardrailed carryover with complete Tier-1 waypoints and a severe-day posture that is fully band-coupled before the dry ramp, then delay the unwind until observed/forecast VPD pressure weakens. Expected outcome: For Saturday: dp_risk_hours 0, pre-dawn VPD-low under 1h, daytime VPD-high lower than Friday despite worse dry air, fewer or no VPD-high moisture-guardrail events, and both-axis compliance at least 65% unless structural heat/temperature-band limits dominate. Cost/water may rise, intentionally, to prevent water budget from bottlenecking severe VPD recovery.

Conditions

Outdoor peak

77.0°F

RH minimum

10.0%

Solar peak

932.0 W/m²

Cloud average

35.0%

Cold saturated pre-dawn around 42-50F and 84-92% RH with indoor VPD 0.37 and dew margin 5.6F, followed by a severe clear dry ramp from late morning through evening: RH 10-24%, outdoor VPD about 1.8-2.9 kPa, solar corrected peak near 890-930 W/m2. Sunday fallback remains dry and warmer by late morning.

Expected stress windows

vpd_lowmedium · 2026-05-23T00:25:00-06:00 to 2026-05-23T09:30:00-06:00

High thresholds 2.45/2.5 overnight, long delays, 55-60s gaps, fog_escalation 0.9-1.0, short 120s sealed residence, bias_cool +4 and modest heat support.

vpd_highhigh · 2026-05-23T10:30:00-06:00 to 2026-05-23T21:30:00-06:00

Fully band-coupled moisture before the VPD ramp: engage 1.0-1.1, all 1.2-1.3, 30/60s delays, 20-25s gaps, fog_escalation 0.15-0.20, min_fog_off 45-60, 180s sealed cap, and 600s backoff.

heatmedium · 2026-05-23T12:00:00-06:00 to 2026-05-23T18:30:00-06:00

Earlier ventilation support with bias_cool 0-1, d_cool_stage_2 2, temp_hysteresis 1.4-1.5, while VENTILATE mist/fog assist protects VPD.

vpd_lowlow · 2026-05-23T23:30:00-06:00 to 2026-05-24T07:30:00-06:00

After outdoor VPD falls below about 1 kPa, unwind toward engage 2.2, all 2.5, 55-60s gaps, fog_escalation 0.9, and short sealed residence.

Parameter rationale

mister_engage_kpa2.45 → 1.0; Saturday 12:00-19:00 RH 10-24%, VPD 1.85-2.87 kPa, solar mostly 576-845 W/m2 raw / up to ~932 corrected; prior plan anchor 1 exposed 14 VPD-high guardrail dispatches.

Avoid repeated moisture-guardrail rewrites and keep VPD-high stress lower than Friday despite worse dry-air pressure.

mister_all_kpa2.5 → 1.2; Active vpd_high is near 0.8 kPa and guardrail guidance wants all-zone near max(1.0, vpd_high+0.25) in live VENTILATE stress.

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

fog_escalation_kpa0.5 → 0.15; Dry peak overlaps 10:30-17:00 fog window and fog is 7x mister effectiveness; PR-A makes vent+fog assist intentional.

Catch stubborn VPD-high while firmware RH/temp/time gates and short sealed caps protect condensation and heat.

mister_pulse_gap_s60.0 → 20.0; RH falls to 10-12% from 15:00-18:00; dry-day lessons call for 15-25s gaps under severe dry pressure.

Prevent humidity collapse between pulses during VENTILATE assist.

mister_engage_delay_s300.0 → 30.0; Recent guardrail clamps shortened long delays during live VPD-high stress.

Start physical pulses promptly once humidity demand exists.

min_fog_off_s180.0 → 45.0; Hot/dry venting can clamp fog-off dwell to 45s; current forecast has severe VPD pressure and healthy dew margin by peak.

Permit an effective fog cadence during the fog window without relying on longer sealed cycles.

bias_cool4.0 → 0.0; Dawn heating needs anti-whipsaw, but noon-to-evening solar/dry pressure needs earlier ventilation rather than delayed cooling.

Reduce heat stress while moisture assist prevents VPD from being abandoned during venting.

mister_water_budget_gal300.0 → 600.0; Severe RH 10-12% dry window plus prior missed water-budget dispatch evidence; validated lesson says the water budget must not bottleneck VPD recovery.

Prevent planner-imposed budget exhaustion during the severe dry ramp.
