Forecast deviation14:02FORECAST_DEVIATIONackedAcknowledged: No tactical change. The 1.51 kPa lower-than-forecast VPD deviation is in the same direction as the established +0.91 kPa near-term forecast overshoot, so this is forecast calibration catching up rather than a new weather regime. Live greenhouse air is 82.9F, 1.30 kPa VPD, 66% RH with a safe 12.5F dew margin; the controller is already in SEALED_MIST_FOG recovery and recent moisture-gap alerts are resolved.

Forecast deviation15:02FORECAST_DEVIATIONackedAcknowledged: No tactical change. The event payload's VPD miss is in the same direction as the known positive VPD forecast bias: forecast over-called dryness (4.70 versus observed outdoor/weather VPD 2.98). The 1.72 kPa gap exceeds the typical 0.94-1.09 kPa bias and fresh history shows outdoor temperature fell from 90.1F to 86.2F while RH rose from 27% to 31%, with live solar only 139 W/m2 versus a 636 W/m2 baseline, indicating earlier cloud/outflow/nowcast catch-up amplified by the bias, not an equipment fault... Resolved 15:02 MDT.
Peak Stress15:05TRANSITIONackedAcknowledged: Peak-stress checkpoint is tracking the active plan: current 82.7F and 1.15 kPa remain inside the latest dispatcher corridor (high edges about 85.2F and 1.19 kPa), dew margin is healthy at 10.9F, controller is IDLE, and all climate/wet relays are off. Existing hot-dry posture is already aggressive and band-coupled (mister engage 0.954 kPa, 22.5 s pulse gap, fog escalation 0.15 kPa), so no further tunable change is justified. Resolved 15:05 MDT.

Reflection

Validating previous cycle: iris-20260822-0620

Previous hypothesis: SUNRISE plan for Saturday 2026-08-22. Friday closed at 56.2 versus a 61.6 seven-day average. VPD was the weaker legacy axis at 40.1% versus 49.3% temperature compliance, and VPD-high dominated at 12.25 h versus 10.45 h heat; VPD-low was 0.53 h, cold 0 h, and dew-risk 0 h. Reliable attributable compliance and utility-cost fields were unavailable. Total water evidence in the assembled context was 337 gal versus a 229 gal seven-day average, and long vent/fan/fog/wet runtimes indicate a cooling-and-misting pattern rather than heating, but meter provenance prevents a dollar-efficiency claim. The completed 2026-08-21 SUNRISE plan iris-20260821-0620 was graded 5/10, matching the deterministic anchor of 5. Its scoped window scored 54.9 with 48.5% temperature compliance and 40.1% VPD compliance; stress was 5.33 h heat, 6.16 h VPD-high, 0.30 h VPD-low, and 0 h cold… Result: Revised final evaluation after the deterministic anchor exposed material delivery evidence not visible in the assembled summary. The 6.0 h window still had a physiologically safe endpoint: score 56.5, temperature compliance 44.9%, VPD compliance 51.0%, 0.84 h heat, 0.43 h VPD-high, 0.24 h VPD-low, 0 h cold, current VPD inside the latest corridor, dew margin 8.7F, and the live moisture-gap alert resolved. But the evaluator found 345 guardrail events, including 222 held, only 6 dispatched, 228 VPD-high-related events, and a 3-point guardrail penalty. The apparent recovery therefore depended heavily on dispatcher repair rather than clean materialization of the requested humid-trough reserve and bridge. Final grade 2/10, matching the anchor: safe measured endpoint but dirty causal delivery and weak temperature corridor time. Today’s replacement plan will align its first hot/dry segments directly with the validated sticky band-coupled posture, avoid a conservative clock-based unwind while dry pressure persists, and keep the intent simpler so guardrails need less repair. Score: 2/10

Hypothesis

Testing: Test whether a short live-edge bridge followed by a nonzero 5-10% humid-trough reserve avoids both the midnight VPD-high moisture gap and the prior zero-wet plan’s heavy guardrail dependence, while a demand-gated 09:00 handoff prepares for the 95F/16% RH day. Expected outcome: By 02:00 MDT, clear the live VPD-high moisture-gap condition without dropping below the VPD corridor or reducing dew margin below 8F. From 02:00-07:30, keep dew-risk at 0 h and VPD-low stress below 0.5 h while retaining a small measured-demand reserve. If the SUNRISE plan is delayed, have band-coupled moisture and precooling authority staged by 07:30 and peak fallback authority by 09:00 before corrected VPD exceeds the morning corridor; keep relay churn bounded and avoid spending water while readings are in corridor.

Hypothesis

Testing: Test whether a simple, guardrail-aligned ramp from in-corridor dawn to +0.05/+0.20 kPa peak wet engagement, 0.15 fog escalation, and a measured-recovery evening reserve lowers held VPD-high guardrail dependence while preserving dew safety on a 96F/14% RH day. Expected outcome: Keep dew-risk at 0 h and VPD-low stress below 1 h while preserving band-coupled wet authority through the dry evening. Hold VPD-high stress below 7 h despite the corrected 3-4 kPa outdoor VPD peak; accept 5-8 h of residual heat stress as physics-limited above 90F. Keep mister use within the 300-gal cap, and reduce held VPD-high guardrail dependence materially below the prior plan’s 222 held events by aligning the requested intent with the validated live-edge posture.

Solar peak

Cloud average

Humid in-corridor dawn followed by a rapid extreme hot/dry ramp. Cloud cover is highly variable from 0-100%; raw VPD peaks at 4.91 kPa and the bounded corrected planning prior remains near 4.0 kPa.

Expected stress windows

vpd_highhigh · 2026-08-23T10:00:00-06:00 to 2026-08-23T23:00:00-06:00

Use +0.05/+0.20-0.25 kPa band-coupled wet engagement, 25-45% peak duty, 0.15 kPa fog escalation while firmware-eligible, and retain a post-fog-window mister reserve until measured recovery.

heathigh · 2026-08-23T11:00:00-06:00 to 2026-08-23T21:00:00-06:00

Use 45-60 minute thermal lead and up to 1.5F solar precooling; preserve VENTILATE wet assist and accept residual physics-limited heat above 90F.

vpd_lowlow · 2026-08-23T06:15:00-06:00 to 2026-08-23T08:30:00-06:00

Float inside corridor with 5-15% demand-gated duty, 9F dew floor, and no target-line chasing after the resolved too-wet alert.

Parameter rationale

mister_engage_kpa0.81 → 1.34; The midday dispatcher VPD high is about 1.29 kPa and corrected outdoor dry pressure exceeds 3 kPa.

Materialize first-stage wet assist near vpd_high plus 0.05 during live peak demand and keep VPD-high stress below 7 h.

mister_all_kpa1.013 → 1.49; Whole-house dry pressure is forecast from late morning through late evening.

Escalate all-zone rotation near the midday high edge plus 0.20 without inventing a priority from the null south sensor.

fog_escalation_kpa0.2 → 0.15; Corrected hot/dry stress overlaps the 07:00-17:00 fog window with an 8.7F live dew margin.

Use the efficient fog path promptly during eligible VENTILATE stress while keeping dew-risk at 0 h.

mister_water_budget_gal120.0 → 300.0; The severe corrected dry window persists through the afternoon and the previous 120-gal cap risks exhausting recovery authority.

Preserve wet-assist authority through the 13:00-20:00 stress window while demand and duty gates prevent in-corridor use.

direct_wet_stress_latest_hour21.0 → 23.0; Raw VPD remains 2.10-2.50 kPa through 22:00 after fog is unavailable.

Avoid a clock-driven evening moisture gap and taper only after measured high-edge recovery.
