Peak Stress	15:08	TRANSITION	acked	Acknowledged: Peak-stress transition checked live climate/equipment/plan/setpoints. Conditions are hot/dry but tracking the active compliance-first plan: temp 85.0F is just above temp_high 84F, VPD 1.77 kPa is above vpd_high 1.22, dew margin is safe at 16.1F, and controller authority is already engaged with VENTILATE, vent + both fans + fog on.

Forecast deviation	16:16	FORECAST_DEVIATION	acked	Acknowledged: FORECAST_DEVIATION assessed: observed outdoor/live VPD is lower than the raw forecast in the same direction as the known positive VPD forecast bias, so this is forecast overcall/catch-up rather than a new hotter/drier regime. Live house is dew-safe (82.4F, VPD 1.42 kPa, RH 63%, dew margin 13.9F) with controller already in SEALED_MIST_FOG and fog on; no equipment fault or unserved wet-assist gap found, so no tunable change.

Decline	19:13	TRANSITION	acked	Acknowledged: TRANSITION decline no-op: current climate is tracking the active plan. House is 79.3F with VPD 1.27 kPa only slightly above the 1.22 high edge, dew margin is healthy at 13.8F, ESP32 mode is IDLE, and all climate/wet relays are off. The existing plan already tapers at 21:00 before the forecast overnight humidity rebound, so an immediate tunable change is not justified. Resolved 19:14 MDT.

Reflection

Validating previous cycle: iris-20260802-0601

Previous hypothesis: SUNRISE plan for Sunday 2026-08-02. Saturday closed at planner_score/compliance 69.2 versus 66.3 seven-day average, with legacy temp compliance 50.5% and VPD compliance 40.7%; VPD was the tighter axis and stress was dual hot/dry: VPD-high 11.06h, heat 10.21h, VPD-low 1.71h, cold 0. Dew safety held with dp_margin_min_f 8.5F and 0 dp-risk hours. Utility cost fields are unavailable; water was elevated at 376 gal versus 213 gal seven-day average, so water increased materially but did not buy enough VPD compliance. I evaluated iris-20260801-2015 at 4/10 versus deterministic anchor 1. The gap is deliberate: I credit correct stress-type anticipation and dew-safe biological outcome, while the anchor correctly penalizes 455 VPD-high guardrail events and 427 held events… Result: Short post-midnight/pre-dawn window remained safe but only moderately compliant. Window scorecard: 70.0 score, temp compliance 43.6%, VPD compliance 39.5%, heat stress 0.24h, VPD-high 0.24h, no cold, no VPD-low, and no dew-risk. The hypothesis correctly anticipated a dew-safe dry-edge night and Monday hot/dry risk; the bounded moisture posture preserved safety but did not create clean VPD recovery before sunrise, and guardrail holds continued on conservative moisture thresholds. Human score 5/10: safe and directionally correct, but short window and weak corridor improvement mean it should not be over-credited. Score: 5/10

Hypothesis

Testing: MIDNIGHT hot/dry reset: keep dew-safe VPD recovery open overnight, pre-stage Monday extreme heat/VPD, then taper only after observed and forecast VPD recovery. Expected outcome: Hold dew-risk hours at 0 and cold stress at 0; reduce controller-attributable VPD-high where wet/fog assist is effective, while accepting physics-limited heat during the 104F outdoor peak; avoid treating extra water alone as a compliance cure if VPD response stays modest.

vpd_highhigh · 2026-08-05T09:00:00-06:00 to 2026-08-05T21:00:00-06:00

re-open band-coupled wet/fog assist for Wednesday hot/dry ramp while preserving Tuesday-night taper until VPD rises

Parameter rationale

mister_engage_kpa0.82 → 1.25; current vpd_high is about 1.22 kPa, live VPD is 1.26 kPa, and Monday corrected VPD remains well above band after sunrise

keep first-stage moisture available near the VPD high edge without relying on repeated guardrail repair

mister_all_kpa1.03 → 1.45; Monday broad dry stress reaches raw VPD 6.8 kPa and RH 7-8%, with east already the dry outlier

permit all-zone assist during confirmed broad dry stress while not suppressing escalation

mister_pulse_gap_s30.0 → 30.0; recent response priors show wet/fog assist improves VPD modestly; hot/dry lessons support short gaps during VENTILATE dry stress

preserve VPD recovery capacity without adding a more aggressive water-only bet

fog_escalation_kpa0.2 → 0.15; Monday and Wednesday VPD-high overlap the 07:00-17:00 fog-safe window with dew margin currently safe

make the 7x fog path available during hot-dry VENTILATE while firmware blocks unsafe fog

mister_water_budget_gal300.0 → 300.0; VPD-high remains the bottleneck but Sunday water use was already high at 501 gal total

avoid budget-limited recovery without raising the water cap beyond the practical daily limit

Result: Weekly strategy plan was superseded after a short pre-dawn/day-start window. Window scorecard showed score/compliance 66.7, temp compliance 51.6%, VPD compliance 44.2%, about 1.30h heat stress and 1.62h VPD-high stress over 0.167d, with no cold stress, essentially no VPD-low, and dew safety preserved. The broad weekly hypothesis correctly identified dual heat/VPD as physics-limited and avoided treating more water as a cure, but the short governed window did not materially improve corridor control and is not strong evidence for the full-week strategy. Human score 4/10: safe and directionally correct, but low representativeness and persistent VPD-high/heat stress limit credit. Score: 4/10

Hypothesis

Testing: Weekly response-prior reset: compliance-first wet/fog assist only in confirmed hot-dry windows; taper through cooler/humid recovery rather than increasing water beyond 300 gal. Expected outcome: Over the next 72h: hold dp_risk_hours at 0 and cold_stress_h at 0; keep Monday/Wednesday VPD-high from worsening despite extreme weather; Tuesday night should avoid VPD-low overshoot; total water should stay below Sunday’s 501 gal unless live VPD remains above band with safe dew margin.

guardrail-clean band-coupled moisture and fog 0.15-0.20 during fog-safe VENTILATE, taper after observed VPD recovery

Parameter rationale

mister_engage_kpa0.79 → 1.27; vpd_high is about 1.22 kPa and Monday/Wednesday corrected VPD remain far above band

keep first-stage moisture available near the high edge during confirmed dry stress without suppressing escalation

mister_all_kpa1.0 → 1.45; broad whole-house dry stress today and Wednesday, but weekly water response was only modest

permit all-zone assist during broad dry stress while avoiding an unlimited water-only bet

mister_pulse_gap_s30.0 → 30.0; hot/dry lessons support short gaps in VENTILATE and recent guardrails repeatedly clamp longer gaps during VPD-high

preserve VPD recovery capacity while relying on duty/resource taper, not longer gaps, to conserve after recovery

fog_escalation_kpa0.2 → 0.15; VPD-high overlaps the 07:00-17:00 fog-safe windows on Monday and Wednesday with dew margin currently >14F

use the 7x fog path where response priors show better VPD-error improvement, while firmware blocks unsafe fog

mister_water_budget_gal300.0 → 300.0; weekly water rose to 501 gal on Sunday without strong VPD compliance, but budget should not bind during safe extreme VPD-high recovery

avoid budget-limited recovery while not raising the cap above the practical maximum

direct_wet_stress_latest_hour21.0 → 21.0; evening recovery is useful, but direct_wet late-hour writes missed recently and Tuesday night turns humid

avoid depending on a missed late-hour extension; taper through ClimateIntent wet_cutoff/resource fields instead

Validating previous cycle: iris-20260802-2015

Previous hypothesis: SUNSET plan for Sunday 2026-08-02. Today closed near the seven-day baseline but remained weak for corridor control: planner_score/compliance 67.3 versus 67.1 seven-day average, with temp compliance 49.4% and VPD compliance 40.5%. VPD was the tighter axis and the dominant stress was VPD-high at 9.71h, followed closely by heat at 8.54h; VPD-low was small at 0.95h and cold was 0. Dew safety held strongly with dp_margin_min_f 8.7F and 0 dp-risk hours. Resource score/cost fields are unavailable, so I am not using kWh or cost for decisions; water context is elevated at roughly 398 gal today versus a 254 gal seven-day average, and recent response priors show fog assist improved VPD error modestly but not enough to overcome structural hot/dry pressure. I evaluated iris-20260802-0016 at 5/10 versus deterministic anchor 3… Result: Validated the primary 2026-08-03 SUNRISE governing window using the provided window scorecard, not the daily rollup. The plan governed 0.591 d (~14.2 h) through the main hot/dry solar window and scored 53.3. It correctly forecast extreme heat (103F predicted vs 102.7F actual) and high VPD/dry stress risk, and it preserved safety: cold stress 0h, VPD-low 0.03h, dew-risk 0h in the assembled context. However the measurable corridor outcome was weak: temp compliance 41.8%, VPD compliance 35.2%, heat stress 5.04h, and VPD-high stress 6.20h during the governed window. Solar was materially undercalled (747 W/m2 predicted vs 1043 W/m2 actual), increasing physics-limited heat and VPD pressure. Rationale grading: band-coupled moisture and fog posture made the right pathways available but did not deliver strong VPD recovery; the 300 gal cap avoided unlimited water escalation but total daily water still reached 346 gal; direct-wet evening recovery did not prove material in this main daytime window. Human score 3/10: correct diagnosis and safe crop/dew outcome, but poor corridor compliance and guardrail/clamp dependence mean the hypothesis was only partially met. Score: 3/10

Hypothesis

Testing: Response-prior discipline: keep peak hot/dry moisture guardrail-clean and compliance-first, but taper Tuesday cool/humid recovery instead of increasing water beyond the 300 gal practical cap. Expected outcome: Maintain 0 dew-risk hours and 0 cold stress; reduce avoidable fog-safe-window VPD-high relative to Sunday while accepting physics-limited heat; keep total water no higher than Sunday unless live VPD remains above band with safe dew margin.

re-open band-coupled wet/fog assist for the Wednesday hot/dry ramp while delaying evening unwind until observed VPD recovery

Parameter rationale

mister_engage_kpa0.95 → 1.27; current vpd_high is about 1.22 kPa and corrected Monday/Wed VPD remains far above band during the dry windows

keep first-stage moisture available near the VPD high edge without suppressing escalation or relying on repeated guardrail repair

mister_all_kpa1.15 → 1.45; broad hot/dry stress today with RH 8-14% through peak/evening and Wednesday dry ramp returning

permit all-zone assist during confirmed broad dry stress while avoiding an unlimited water-only bet

mister_pulse_gap_s30.0 → 30.0; hot/dry lessons support short gaps during VENTILATE dry stress and recent guardrails repeatedly clamp longer gaps

preserve VPD recovery capacity while using evening/tuesday taper rather than a longer peak gap to conserve water

fog_escalation_kpa0.3 → 0.15; VPD-high overlaps the 07:00-17:00 fog-safe window today and Wednesday, with current dew margin 11.8F

make the 7x fog path available during hot-dry VENTILATE while firmware blocks unsafe fog

mister_water_budget_gal300.0 → 300.0; Sunday water use was high at 501 gal with only modest VPD benefit, but budget should not bind during safe extreme VPD-high recovery

avoid budget-limited recovery without raising the cap above the practical daily limit

direct_wet_stress_latest_hour21.0 → 23.0; Monday evening remains very dry above the VPD corridor with healthy dew margin expected

permit bounded evening dry-stress recovery today, then taper back for Tuesday humid-night risk through ClimateIntent wet cutoff/resource fields

Validating previous cycle: iris-20260803-0602

Previous hypothesis: SUNRISE plan for Monday 2026-08-03. Sunday closed at score/compliance 72.9 versus 67.1 seven-day average, but axis control remained weak: temp compliance 47.6% and VPD compliance 38.1%. VPD was the bottleneck, with VPD-high 12.65h slightly above heat stress 10.98h; VPD-low was only 0.95h and cold was 0h. Dew safety held with dp_margin_min_f 8.7F and 0 dp-risk hours. Resource cost fields remain unavailable, so I am not using kWh/cost for decisions; water was very high at 501 gal total and 244 gal misting versus 254 gal seven-day total-water average. I evaluated iris-20260803-0016 at 5/10 versus deterministic anchor 4. The short pre-dawn window was safe and directionally correct but only moderately compliant, with 160 VPD-high guardrail events and 155 held. The anchor gap is small: I credit safe dew outcome, while the anchor correctly penalizes dirty materialization and weak VPD recovery… Result: Evaluated the Monday sunset plan over its governed 0.169 d window using the window scorecard. The plan correctly avoided cold stress, VPD-low overshoot, and dew risk, but corridor control remained poor during the expected evening recovery: window score/compliance 40.0, temp compliance 46.0%, VPD compliance 35.0%, heat stress 0.53 h, VPD-high stress 0.64 h, cold/VPD-low 0 h. Daily Monday context was also weak: score 63.3 vs 65.9 7d average, VPD was the bottleneck at 41.8% compliance, and VPD-high dominated at 12.54 h versus heat 10.18 h. The hypothesis correctly shifted away from daytime peak aggression, but the actual near-midnight recovery did not bring VPD into corridor strongly enough and recent guardrail history shows overly conservative moisture requests continue to be clamped/held during dry-edge conditions. Human score 3/10: safe dew/cold outcome, but weak VPD recovery and low compliance mean the taper was only partially successful. Score: 3/10

Hypothesis

Testing: Overnight taper after hot/dry day: reduce mist/fog duty once live VPD is near band and dew margin is safe, then reopen only moderate moisture for Tuesday’s cooler dry ramp. Expected outcome: Maintain 0 dew-risk hours and 0 cold stress overnight; keep VPD-low under 0.5h; reduce overnight wet runtime/churn relative to the prior hot-dry daytime posture while allowing bounded recovery if VPD rises above band before midnight.

Conditions

RH minimum

32.0%

Solar peak

Cloud average

Sunset after hot/dry day: live house is safe, near-band, and dew margin is 12F. Next 12h cools from 78F to low 60s with raw VPD dropping from dry evening values to near/under band by midnight; forecast VPD has a positive bias so over-wet/churn risk is the main overnight concern after the first dry evening hours.

Expected stress windows

vpd_highmedium · 2026-08-03T20:13:00-06:00 to 2026-08-03T23:30:00-06:00

keep bounded evening edge recovery available while dew margin is healthy, but do not keep the full daytime fog/mist posture after observed VPD is near band

vpd_lowlow · 2026-08-04T00:00:00-06:00 to 2026-08-04T07:30:00-06:00

high dew-margin floor, low mist duty, wider fog escalation, higher resource sensitivity, and stronger relay-churn penalty

Parameter rationale

mister_engage_kpa1.0 → 1.34; live VPD is 1.07 kPa against vpd_high about 1.22, and raw forecast VPD drops near band by midnight with known positive VPD bias

avoid unnecessary overnight pulses while preserving edge recovery if VPD rises above band

mister_all_kpa1.2 → 1.62; zone spread is currently small and the night cools/humidifies, so whole-house all-zone mist escalation should not be easy to trigger

reduce water/churn and VPD-low risk overnight without closing first-stage recovery entirely

mister_pulse_gap_s30.0 → 55.0; humidity holds better after sunset and today already used heavy fog/wet runtime

cut overnight mist cycling while keeping dew safety above the 5F risk floor

fog_escalation_kpa0.25 → 0.45; fog is outside its normal time window overnight and the main risk shifts from hot-dry recovery to over-wet/churn

keep the heavy 7x fog path effectively held back until Tuesday daytime dry evidence returns

mister_water_budget_gal300.0 → 200.0; cost fields are unavailable but water context is above the 7d average and overnight VPD should recover naturally

avoid continuing daytime water posture into a cooling night while retaining enough budget for bounded edge recovery
