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

Hypothesis

Testing: Test whether a MIDNIGHT reset that is guardrail-clean immediately, conservative only during the cool pre-dawn window, and explicitly band-coupled before the dry ramp can reduce VPD-high guardrail holds while avoiding new VPD-low/dew carryover despite degraded telemetry. Expected outcome: By the next review: climate telemetry freshness restored or platform issue flagged; dp-risk remains 0h; Sunday VPD-high guardrail held events are materially lower than the 83 held events from iris-20260530-2023; VPD-high stress is under 3h if telemetry recovers; cost stays near or below USD 5.50 unless fog is needed for confirmed VPD-high recovery; no new VPD-high no-moisture-assist alerts after 08:00.

Midnight context is degraded/stale but last reported indoor state was VPD-high with healthy dew margin. Sunday forecast is clear, dry, high-solar, RH 11-17%, VPD 2.6-3.3 kPa. Prior plan anchor 1/score 2 due 177 VPD-high guardrail events.

Expected stress windows

vpd_highmedium · 2026-05-31T00:15:00-06:00 to 2026-05-31T01:30:00-06:00

Keep immediate moisture thresholds guardrail-clean and band-coupled because stale last climate was still dry-side and guardrail holds persisted.

vpd_lowmedium · 2026-05-31T02:00:00-06:00 to 2026-05-31T06:30:00-06:00

High dew-margin floor and resource-sensitive low duty while outdoor VPD is 0.5-0.7 kPa; dispatcher guardrail may still hold if observed VPD remains high.

vpd_highhigh · 2026-05-31T08:00:00-06:00 to 2026-05-31T21:30:00-06:00

Band-coupled moisture: engage near vpd_high+0.05, all-zone near +0.25, fog escalation 0.15-0.20, short gaps, 300 gal budget, dew floor 8F.

heatmedium · 2026-05-31T11:00:00-06:00 to 2026-05-31T18:00:00-06:00

Earlier fan2/all-fan cooling readiness with solar lead while accepting structural cooling limits if exhaust cooling saturates.

Parameter rationale

mister_engage_kpa1.23 → 1.23; Last reported VPD 1.40 above vpd_high 1.18 and retrieved lessons 131/134/137 require band-coupled moisture while VPD-high is unrecovered.

Stop adding conservative moisture rows that the VPD-high guardrail must hold or clamp.

mister_all_kpa1.43 → 1.43; Sunday dry ramp reaches RH 11-17% and VPD above 3 kPa; all-zone rotation should stay near vpd_high+0.25.

Keep distributed mist available during whole-house dry stress instead of forcing fog alone to carry recovery.

fog_escalation_kpa0.25 → 0.15; Dry stress overlaps 07:00-17:00 fog window with healthy daytime dew margin expected.

Allow PR-A vent-fog assist during peak VPD-high before VPD drifts far above band.

mister_pulse_gap_s30.0 → 20.0; Peak RH near 11-17% and VPD 2.6-3.3 kPa require short recovery gaps when wetting is safe.

Reduce VPD-high stress without increasing pulse length first.

direct_wet_stress_min_dew_margin_f12.0 → 8.0; Pre-dawn remains conservative, then dry daytime heat should widen dew margin before wet recovery demand peaks.

Keep dawn condensation protected while not blocking dry-ramp recovery unnecessarily.

cool_stage2_over_high_f1.9 → 0.6; Solar near 900 W/m2 and peak 82F will create heat pressure after late morning.

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

mister_water_budget_gal120.0 → 300.0; Compliance is priority during a severe dry ramp and Saturday water was not the binding cost risk.

Prevent water budget from limiting VPD recovery during peak and evening dry windows.
