Hypothesis

Testing: Guardrail-compatible severe-day continuation: keep wet/fog assist band-coupled through observed recovery instead of clock taper; success means fewer guardrail-held events than iris-20260724-0553 while maintaining 0 dp-risk hours. Expected outcome: For 2026-07-25, preserve dp_risk_hours at 0, keep VPD-low stress near 0, reduce VPD-high severity versus recent 6-15h hot-dry days if wet assist materializes, and treat peak heat as partly physics-limited rather than spending resources on target hugging.

severe hot-dry Saturday with dew-safe warm midnight, VPD near the high edge, current VENTILATE, and another severe Sunday; semantic retrieval blocked by missing OPENAI_API_KEY, plan coverage and static context missing

dew-safe band-coupled mist permissive overnight; no fog until firmware window but do not resource-close wet assist while VPD is near high edge

vpd_highhigh · 2026-07-26T08:00:00-06:00 to 2026-07-26T22:00:00-06:00

repeat guardrail-compatible severe-day wet/fog posture and avoid clock-only evening taper until observed VPD is below the high edge

same capacity-aware cooling posture; do not spend effort target-hugging inside the corridor

vpd_highmedium · 2026-07-27T08:00:00-06:00 to 2026-07-27T20:00:00-06:00

moderate wet assist for a cloudier but still dry Monday, with resource sensitivity rising only after recovery

Parameter rationale

mister_engage_kpa0.82 → 1.27; current VPD is about 1.20 kPa near the active high edge and corrected daytime VPD remains several kPa above band

keep S1 mist available near the high edge without relying on guardrail rewrites while dew margin remains safe

mister_all_kpa1.02 → 1.47; forecast severe whole-house dry stress Saturday/Sunday and zone VPD spread recently exceeded 0.5 kPa

allow all-zone rotation during broad dry stress while preserving wider deadband for zone outliers

fog_escalation_kpa0.2 → 0.15; hot-dry stress overlaps the 07:00-17:00 fog window and dew margin is currently 15F

use the 7x fog path during hot-dry VENTILATE when firmware gates allow, reducing VPD-high severity

mister_water_budget_gal180.0 → 300.0; two consecutive severe hot-dry days are forecast and recent resource conservation did not produce strong VPD compliance

avoid budget-limited VPD recovery during safe dry stress

mister_pulse_gap_s30.0 → 22.0; active dry-RH lessons call for 15-25s gap during dry heat and guardrails clamp long gaps during VPD-high stress

increase useful wet duty during confirmed VPD-high windows and reduce reliance on dispatcher clamps
