Peak Stress15:05TRANSITIONackedAcknowledged: Peak-stress conditions are being handled by the existing plan: VENTILATE has vent, both fans, and fog actively served; effective moisture settings are already aggressive and band-coupled (engage 0.956 kPa, all-zone 1.106 kPa, 22 s gap, fog escalation 0.15 kPa, 300 gal budget).

Forecast deviation18:16FORECAST_DEVIATIONackedAcknowledged: Live outdoor weather is materially hotter and drier than the fresh forecast (84.8F/40% RH versus 73F/58% near 19:00), opposite the recent forecast-bias direction, so this is a genuine near-term forecast miss rather than bias catch-up or stale-ingestor data.

At 18:49 MDT the controller is IDLE and all climate/wet equipment is off; solar is 12 W/m2, dew margin is safe at 10.3F, and the east occupied zone remains modestly dry at 1.22 kPa while west is 0.85 kPa. An immediate moisture unwind would be premature, and the existing plan already stages the appropriate taper at 19:30 (engage 1.0 kPa, 45 s gap, fog escalation 0.5) followed by a stronger 22:30 overnight posture (engage 1...

Previous hypothesis: SUNRISE plan for Friday 2026-08-21. Thursday closed at 58.9 versus a 61.4 seven-day average. VPD was the weaker legacy axis at 42.3% versus 49.0% temperature compliance, while stress was effectively co-dominated by 10.41 h heat and 10.37 h VPD-high; VPD-low was 1.61 h, cold 0 h, and dew-risk 0 h. Graded/attributable compliance and reliable total/electric/gas cost were unavailable. Total water was 370 gal versus a 183 gal seven-day average and mister water was 122 gal, while long vent/fan/fog runtimes indicate a cooling-and-misting resource pattern rather than heating. The completed MIDNIGHT plan iris-20260821-0017 is graded 4/10 versus deterministic anchor 2. It recovered the house to 68.78F and 0.801 kPa inside the active corridor with only 0.11 h VPD-low and no dew-risk, so I gave limited physiological credit. The anchor more strongly and appropriately penalizes weak 50… Result: Revised final evaluation after the deterministic anchor exposed material delivery evidence not visible in the assembled transition excerpt. The 5.5 h window scored 62.9, with 51.0% temperature compliance, 49.8% VPD compliance, 1.87 h heat, 1.71 h VPD-high, 0.18 h VPD-low, and 0 h cold. Physiological staging was directionally safe, but causal materialization was poor: 125 of 128 scoped guardrail events were held, all associated with VPD-high handling. That means the acceptable low-side outcome depended on dispatcher repair rather than the requested posture landing cleanly. The later morning handoff remained unobserved. Final grade 3/10, matching the anchor: safe outcome but dirty materialization, middling corridor time, and no credit for future goals. The replacement plan will avoid a live dry-bridge request because current VPD is already inside band and will use a clean humid-night zero-wet posture before a bounded morning handoff. Score: 3/10

Hypothesis

Testing: Test whether a guardrail-compatible 25% post-midnight live-edge bridge, followed by a gradual 15% to 5% pre-dawn taper and a demand-coupled morning restage, clears the current high edge without low-side overshoot while avoiding another no-moisture VENTILATE gap. Expected outcome: By 03:00 MDT, recover measured house VPD to the dispatcher-owned high edge or below if thermal pressure permits, while keeping VPD-low stress below 0.5 h and dew-risk at 0 h through 08:30. If recovery lags, sticky VPD-high guardrails should retain band-coupled wet authority rather than allowing a forecast-only shutdown. From 08:30 onward, restore live-demand moisture and thermal lead before the 10:00-12:00 hot-dry ramp; keep controller-attributable VPD-high misses below 2 h through the handoff, with residual heat above ambient treated as capacity-limited.

Validating previous cycle: iris-20260821-1956

Previous hypothesis: SUNSET plan for Friday 2026-08-21. Today closed at legacy planner score/compliance 63.7, above the 61.6 seven-day average. VPD was the weaker axis at 45.2% versus 52.9% temperature compliance. VPD-high dominated at 8.70 h, narrowly ahead of 7.59 h heat; VPD-low was 0.53 h, cold was 0 h, and dew safety held at an 8.5F minimum with 0 risk hours. Graded/attributable compliance and reliable electric, gas, water-cost, and total-cost fields are unavailable, so no dollar-cost or gas/electric attribution is claimed. Assembled total water was 337 gal versus a 229 gal seven-day average, while long vent, fan, fog, and water runtimes indicate a cooling-and-wet-assist resource pattern. The completed SUNRISE plan iris-20260821-0620 is graded 5/10, exactly matching its deterministic anchor. Its scoped window scored 54.6, with 45.4% temperature compliance, 38.8% VPD compliance, 3.67 h heat, 4… Result: Evaluated the elapsed 2026-08-22 SUNRISE plan through the SUNSET replacement boundary. Its 13.4 h scoped window scored 54.4, with temperature compliance 44.1% and VPD compliance 43.1%. Stress was 3.95 h heat, 3.63 h VPD-high, 0.37 h VPD-low, and 0 h cold; the daily dew margin minimum was 8.2F with 0 risk hours. The predicted heat and VPD-high regimes occurred, VPD-high stayed below the planned 8 h bound, VPD-low stayed below 1 h, and dew safety held. Recent action priors show VENT_COOL_MIST_ASSIST and VENT_COOL_FOG_ASSIST improved both temperature and VPD error, so the band-coupled wet-assist strategy was directionally useful. However, only about 44% axis compliance means corridor recovery remained weak, solar pressure materially exceeded the plan prior, 39 transition expectations were missed, and total water evidence was 295 gal versus a 265 gal seven-day average with no reliable dollar-cost fields. Grade 4/10: correct stress classification and bounded low-side/dew outcomes, but weak corridor time and dirty/incomplete materialization. The replacement plan will separate humid-night suppression from the next dry morning handoff and avoid target chasing while current air is in corridor. Score: 4/10

Hypothesis

Testing: Test whether live-demand staging—15% mist authority at the morning ramp, 30-45% through peak stress with 0.15 kPa fog escalation, then a measured-recovery evening bridge—improves VPD corridor time without adding more than 1 h VPD-low stress or any dew-risk. Expected outcome: Keep dew-risk at 0 h and VPD-low stress below 1 h. On the severe hot/dry ramp, keep VPD-high stress below 8 h and heat stress within the expected 5-8 h physics-limited range, while preserving band-coupled vent-mist/fog authority whenever live VPD exceeds the dispatcher-owned edge. Target a daily legacy score/compliance above Friday’s 56.2, no clock-driven evening moisture gap before measured recovery, and no mist-budget exhaustion before the 14:00-17:00 stress peak.

vpd_lowlow · 2026-08-22T06:20:00-06:00 to 2026-08-22T08:30:00-06:00

Float inside the crop corridor with 5-15% demand-coupled duty, a 9-10F dew floor, and no target-line chasing.

vpd_highhigh · 2026-08-22T10:00:00-06:00 to 2026-08-22T22:30:00-06:00

Use +0.05/+0.20-0.25 kPa band-coupled engagement, 30-45% peak duty, 0.15 kPa fog escalation during the firmware-safe window, and retain evening mister authority until measured recovery.

heathigh · 2026-08-22T11:00:00-06:00 to 2026-08-22T20:00:00-06:00

Use 45-60 minute thermal lead and up to 1.5F solar precooling; preserve vent moisture assist and accept residual physics-limited heat once outdoor air exceeds the served edge.

Parameter rationale

mister_engage_kpa0.8 → 1.34; The midday VPD high is about 1.29 kPa and corrected dry pressure remains severe.

Materialize first-stage wet assist near vpd_high plus 0.05 and keep VPD-high stress below 8 h.

mister_all_kpa1.01 → 1.49; Whole-house dry pressure is forecast from late morning through evening.

Materialize broad escalation near the midday high edge plus 0.20 without inventing a priority from the null south sensor.

mister_engage_delay_s37.5 → 30.0; The live VPD ramp historically accelerates after 09:00 and can outpace long engagement dwell.

Start physical wet assist promptly after confirmed band-edge demand without pre-wetting dawn air.

mister_all_delay_s75.0 → 60.0; Corrected VPD remains above the crop corridor through the midday peak.

Escalate all-zone rotation promptly when first-stage pulses do not recover the edge.

mister_pulse_gap_s41.25 → 20.0; Outdoor temperature reaches 94-95F with 20-21% RH and 813 W/m2 solar.

Provide useful peak mist duty while keeping VPD-low stress below 1 h through live-demand and dew gates.

fog_escalation_kpa0.2 → 0.15; Hot/dry stress overlaps the 07:00-17:00 fog window and dawn dew margin is 10.2F.

Use the 7x-effective fog path sooner during eligible VENTILATE stress while maintaining zero dew-risk hours.

mister_water_budget_gal120.0 → 300.0; The corrected hot/dry window persists through late afternoon and yesterday's total-water reading is not a clean mister-only signal.

Prevent budget exhaustion before the 14:00-17:00 peak while demand and duty gates limit waste.

direct_wet_stress_latest_hour21.0 → 23.0; Raw VPD remains 1.25-1.95 kPa through 22:00 after fog is unavailable.

Avoid another clock-driven evening moisture gap and taper only after measured recovery.

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 materially worse delivery than the assembled transition summary. The 4.4-hour window scored 44.4, with 41.1% temperature compliance and 48.0% VPD compliance; scoped stress was only 0.03 h heat, 0.02 h VPD-high, 0 h cold, and 0 h VPD-low, and dew safety held. Those safe elapsed outcomes earn limited physiological credit, but the evaluator found 293 guardrail events, including 137 held, 52 dispatched, 189 VPD-high events, and a 3-point guardrail penalty. Clean regime separation therefore failed: the requested humid-night posture depended heavily on dispatcher repair, multiple requested dew-floor and tactical writes did not land, and the future 08:30 handoff is unobserved. At replacement, 72.3F and 0.90 kPa were above the live 72.0F/0.764 kPa high edges, VENTILATE had no moisture assist, and alert 10402 remained open. Final grade 1/10, matching the anchor. The next plan will use a simple live-edge moisture bridge immediately, taper only after measured recovery into the humid trough, and stage a bounded hot/dry handoff without unsupported or repeatedly missed raw tunable expectations. Score: 1/10

Hypothesis

Testing: Test whether a clean zero-wet humid-night posture with an explicit 08:30 live-demand hot/dry handoff preserves zero dew-risk and reduces VPD-low exposure without repeating the prior plan’s VPD-high guardrail dependence. Expected outcome: Keep dew-point risk at 0 h and VPD-low stress below 2 h through the saturated overnight trough, with no unnecessary wet-assist runtime while the house remains inside or below the VPD corridor. Avoid heater/vent whipsaw through high relay-churn penalties and useful-exchange-only economizer thresholds. If SUNRISE replacement is delayed, restore band-coupled +0.05/+0.25 kPa moisture authority, 30% demand-limited duty, 0.20 fog escalation, and a 300-gal daily cap by 08:30 before the rapid 97F/14% RH ramp.

Expected stress windows

vpd_lowmedium · 2026-08-22T21:00:00-06:00 to 2026-08-23T08:30:00-06:00

Use zero wet duty, a 10-12F dew floor, stable dwell, and outdoor exchange only when temperature and dew-point advantages are useful.

vpd_highhigh · 2026-08-23T10:30:00-06:00 to 2026-08-23T22:00:00-06:00

If SUNRISE replacement is delayed, restore +0.05/+0.25 kPa band-coupled moisture, 30% duty, 0.20 fog escalation, and a 300-gal cap from 08:30.

heathigh · 2026-08-23T11:30:00-06:00 to 2026-08-23T20:00:00-06:00

Use a 60-minute lead and 1.5F solar precooling; preserve vent wet-assist authority and accept residual physics-limited heat above 90F.

Parameter rationale

mister_water_budget_gal300.0 → 100.0; Outdoor RH rises to 90-97% and raw VPD falls to 0.06-0.23 kPa overnight.

Prevent unnecessary overnight wet-assist demand and keep VPD-low stress below 2 h.

direct_wet_stress_min_dew_margin_f8.0 → 12.0; The current dew margin is 8.3F and saturated outdoor air is forecast through dawn.

Preserve zero hours below the 5F condensation-risk margin.

direct_wet_stress_latest_hour21.0 → 19.0; The house is already in corridor at sunset and humidity rises sharply after 21:00.

Close the evening wet surface before the saturated trough instead of spending water to target-hug.

fog_escalation_kpa0.5 → 0.2; Sunday raw VPD rises above 1.7 kPa by 11:00 and reaches 5.14 kPa at 15:00.

Restore the efficient fog path for live hot/dry demand if the SUNRISE replacement is delayed.

mister_water_budget_gal100.0 → 300.0; The corrected Sunday hot/dry prior remains severe from late morning through evening.

Avoid moisture-budget exhaustion during the following heat/VPD-high window.
