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

Hypothesis

Testing: Guardrail-compatible midnight reset: wet restraint through humid pre-dawn, full band-coupled wet/fog assist only during confirmed dry stress, and early Friday severe-day staging. Expected outcome: By sunrise, dp_risk_hours remains 0.0 and VPD-low stress remains under 1h. During Wednesday peak, VPD-high severity should improve versus Tuesday’s 12.86h baseline without increasing dew risk; guardrail-held materialization should fall because the plan uses bounded ClimateIntent instead of raw invalid taper values. Total water may rise toward the 300 gal mist-assist cap on live dry stress, but overnight/storm-window water should stay restrained.

Expected stress windows

vpd_lowmedium · 2026-07-22T00:15:00-06:00 to 2026-07-22T07:30:00-06:00

hold wet duty low, keep dew margin floor high, and let dehum/vent authority handle humid air; do not spend water before live dry ramp

vpd_highhigh · 2026-07-22T09:30:00-06:00 to 2026-07-22T21:00:00-06:00

reopen band-coupled moisture near vpd_high+0.05, all-zone near +0.20 to +0.25, and fog escalation near 0.15-0.20 while dew margin is safe

heathigh · 2026-07-22T12:00:00-06:00 to 2026-07-22T18:30:00-06:00

thermal lead, solar pre-cooling, all-fans cooling authority already on, and evaporative assist; accept physics-limited peak heat rather than target hugging

vpd_lowhigh · 2026-07-22T23:00:00-06:00 to 2026-07-23T09:30:00-06:00

sharp overnight taper for forecast RH 88-94% and VPD 0.13-0.36 kPa; protect dew margin and avoid fog/mist carryover

vpd_highmedium · 2026-07-23T11:00:00-06:00 to 2026-07-23T16:30:00-06:00

moderate wet/fog assist only during the dry pocket, tapering early for 90% precipitation/storm risk

vpd_highhigh · 2026-07-24T08:30:00-06:00 to 2026-07-24T21:00:00-06:00

early severe-day band-coupled wet/fog posture with full dry-stress water budget while dew margin remains healthy

Parameter rationale

mister_water_budget_gal120.0 → 300.0; Wednesday and Friday dry ramps exceed the served VPD band by late morning, while Tuesday conservation still left VPD compliance near 40% and dew safety held

avoid budget-limited recovery during live safe VPD-high stress while using overnight and storm-window taper for conservation

mister_engage_kpa0.82 → 1.27; current VPD is in band but Wednesday corrected VPD rises above band from about 09:00 onward; current vpd_high context is about 1.22 kPa

make S1 moisture available near vpd_high+0.05 during confirmed dry stress without requesting values the guardrail must rewrite

mister_all_kpa1.02 → 1.47; hot-dry VENTILATE utilization was high and VENT_COOL_MIST_ASSIST recently improved VPD error by about 0.15 kPa when served

allow all-zone rotation near vpd_high+0.25 during meaningful house-wide dry stress while avoiding overnight all-zone wetting

fog_escalation_kpa0.2 → 0.15; daylight fog window overlaps Wednesday and Friday hot-dry peaks, dew risk is currently 0, and fog is the 7x moisture path when misters are insufficient

reduce VPD-high severity during hot-dry VENTILATE without relying on sealed-mist heat trapping

mister_pulse_gap_s30.0 → 30.0; recent VPD-high guardrail already holds long gaps down near 30s; direct ClimateIntent will request duty rather than invalid raw gap values

stay guardrail-compatible and reduce held/missed tactical materialization while preserving useful wet duty during peak stress
