Dew-risk was 0 h; live overnight recovery later reached VPD 0.85 kPa with 9.3 F dew margin. The plan’s hot-dry daytime forecast was not evaluated inside this overnight window; execution fidelity and forecast-to-window alignment limited confidence. Score: 6/10

Hypothesis

Testing: Require live VPD confirmation at the sunrise ramp before escalating hot-dry wet assist. Expected outcome: Keep overnight dew-risk and VPD-low exposure at 0 h, stabilize pre-dawn staging, and have bounded wet assist available before the 94F/15%RH peak.

Cool humid pre-dawn followed by an extreme hot-dry afternoon; prior forecast materially overpredicted dryness, so live VPD gates the ramp.

Expected stress windows

vpd_highhigh · 2026-09-13T10:30:00-06:00 to 2026-09-13T17:30:00-06:00

Band-coupled mist assist, fog excess 0.15-0.25, preserve 8F dew floor.

heathigh · 2026-09-13T11:00:00-06:00 to 2026-09-13T18:30:00-06:00

Precondition before peak, ventilate, and accept capacity-limited heat above the served envelope.

Parameter rationale

mister_engage_kpa1.6 → 1.05; Live VPD gates the 07:30 ramp; corrected afternoon VPD reaches 3.8-4.5 kPa.

Start wet assist near the active high edge without repeating the prior forecast-only overreaction.

fog_escalation_kpa0.4 → 0.15; 94F and 15% RH are forecast during the 07:00-17:00 fog-safe window.

Offer heavy assist earlier while firmware dew, RH, temperature, and time gates remain authoritative.

mister_pulse_gap_s45.0 → 20.0; Dryness accelerates from 10:00 through 17:00 after a humid dawn.

Sustain bounded daytime wet assist, with overnight gaps long enough to avoid another wet-band alert.

Hypothesis

Testing: Live-gate the 09:00 wet-assist ramp: require measured VPD recovery from dawn wet drift before peak escalation. Expected outcome: Maintain 0 h dew-risk and VPD-low stress; improve controller-attributable VPD compliance during the 11:00-20:00 hot/dry window while accepting capacity-limited heat.

RH minimum

14.0%

Solar peak

Cloud average

Cool humid dawn, then hot dry peak; prior overnight wet drift requires a live-gated ramp.

Expected stress windows

vpd_highhigh · 2026-09-13T10:00:00-06:00 to 2026-09-13T20:00:00-06:00

Band-coupled vent-mist assist; fog excess 0.15-0.20 while safety gates permit.

heathigh · 2026-09-13T12:00:00-06:00 to 2026-09-13T19:00:00-06:00

Pre-cool and ventilate; accept capacity-limited heat above the served envelope.

Parameter rationale

mister_engage_kpa1.6 → 1.3; VPD 2.62 at 11:00 to 4.72 at 15:00; live ramp gating follows wet dawn.

Start vent-mist assist near the daytime band edge without extending dawn wet drift.

fog_escalation_kpa0.4 → 0.2; RH 14% and 94F occur inside the 07:00-17:00 fog-safe window.

Offer heavy assist earlier while firmware dew, RH, temperature, and time gates remain authoritative.

mister_pulse_gap_s45.0 → 22.0; Dry peak persists through 17:00; preserve an 8F dew floor after zero dew-risk yesterday.

Sustain bounded peak assist, then taper only after measured VPD recovery.

vpd_highmedium · 2026-09-13T20:00:00-06:00 to 2026-09-13T21:30:00-06:00

Allow short band-coupled wet assist; taper only after measured VPD clears high edge.

vpd_lowmedium · 2026-09-13T23:00:00-06:00 to 2026-09-14T07:00:00-06:00

Widen wet gap, suppress fog, keep dew-margin floor and stable heater/vent dwell.

Parameter rationale

mister_pulse_gap_s45.0 → 60.0; Forecast VPD 0.42 at 23:00 to 0.24 at 05:00.

Avoid wet-band drift and preserve zero dew-risk hours after evening recovery.

mister_engage_kpa1.6 → 1.04; Measured VPD 0.85 with 9.3F margin; evening forecast briefly reaches 2.0.

Permit a bounded recovery bridge, then let the high-edge gate taper wetting.

fog_escalation_kpa0.4 → 0.35; Fog is unnecessary after 22:00 as forecast VPD drops below 0.65.

Prevent overnight fog over-humidification while retaining bounded evening recovery.

Interior Light Evidence

  • Crop DLI: unavailable
  • Reason: source_day_incomplete
  • Provenance: legacy_invalid_exterior_proxy_plus_fixture_estimate
  • Validity: dli-validity-v1; 2024-01-01T00:00:00+00:00 → open
  • Qualified-light minutes and photoperiod remain independent of unavailable DLI.

Stress Hours

  • Heat stress (>85°F): 3.9h
  • VPD stress (>2.0 kPa): 9.1h
  • Cold stress (<55°F): 9.4h
