Reflection

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

Hypothesis

Testing: Test whether a midnight reset that is conservative only while VPD is actually below band, then switches to fully guardrail-clean band-coupled moisture before the 10:00 dry ramp, reduces VPD-high guardrail holds versus the 127 held events in the SUNSET plan while keeping dp-risk at 0h. Expected outcome: By the next SUNSET: no unresolved moisture-assist alerts after 10:00, VPD-high guardrail held events materially lower than 127, dp-risk remains 0h, VPD-low stays under 1.0h after 08:30, and cost remains under USD 5 unless peak heat/fog demand requires extra compliance spend.

Humid low-VPD midnight after guardrail-heavy sunset unwind; clear dry high-solar Saturday ramp reaches RH 11-16%, VPD near 3 kPa, solar near 900-1000 W/m2.

Expected stress windows

vpd_lowmedium · 2026-05-30T00:15:00-06:00 to 2026-05-30T08:30:00-06:00

Suppress wet/fog with high dew floor, high resource sensitivity, and stable dwell while VPD remains below band and dew margin is modest.

vpd_highhigh · 2026-05-30T10:00:00-06:00 to 2026-05-30T22:30:00-06:00

Use guardrail-clean band-coupled mist/fog: engage near vpd_high+0.05, all-zone near +0.20-0.25, fog escalation 0.15-0.20, short gaps, and no clock unwind until observed recovery.

heatmedium · 2026-05-30T11:00:00-06:00 to 2026-05-30T17:30:00-06:00

Use anticipatory cooling/all-fan readiness while accepting structural limits if solar outruns fan cooling.

Parameter rationale

mister_engage_kpa1.07 → 1.23; Dry ramp begins near 10:00 with RH 40% then falls to 11-16% by 11:00-15:00; lessons 131/134 require band-coupled moisture during VPD-high VENTILATE.

Avoid another guardrail-heavy handoff and make S1 mist eligible near the active VPD high edge.

mister_all_kpa1.27 → 1.43; Whole-house dry ramp reaches VPD near 3 kPa with high solar; all-zone rotation should be near vpd_high+0.25, not disabled by conservative absolute thresholds.

Use distributed mist support instead of leaving fog or one zone to carry VPD recovery.

fog_escalation_kpa0.35 → 0.15; Dry stress overlaps the 07:00-17:00 fog window with healthy daytime dew margin expected.

Allow PR-A vent-fog assist before VPD drifts far above band while firmware RH/temp/dew gates remain active.

mister_pulse_gap_s60.0 → 20.0; RH falls to 11-16% during hot VENTILATE pressure; long gaps were repeatedly held by the VPD-high guardrail.

Keep VPD closer to band between pulses without increasing pulse duration first.

direct_wet_stress_min_dew_margin_f8.0 → 8.0; Midnight dew margin is only 6.8F, but daytime dry heat should widen margin before wet recovery is needed.

Block marginal dawn wetting while allowing dry-ramp recovery once dew margin is safe.

cool_stage2_over_high_f1.0 → 0.6; Saturday solar approaches 900-1000 W/m2 and prior days paired heat and VPD stress in VENTILATE.

Bring fan2 and all-fan readiness closer to the high edge before peak solar.

mister_water_budget_gal300.0 → 300.0; Compliance is priority during a severe dry ramp; water was not the binding cost risk yesterday.

Prevent water budget from silently limiting VPD recovery during the dry window.
