Peak Stress15:08TRANSITIONackedAcknowledged: Peak-stress transition checked. Live conditions are tracking the active SUNRISE plan: temp 83.4F is just below temp_high 84F, VPD 1.27 kPa is only slightly above vpd_high 1.22 with dew margin 11.8F, and the controller is in SEALED_MIST_FOG/recovery cycling. Current tactical posture is already band-coupled and near the aggressive edge (fog_escalation_kpa 0.15, mister_engage_kpa 1.26, mister_all_kpa 1.44, mister_pulse_gap_s 30), so there is no higher-confidence single tunable change to make now.

Reflection

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 Tuesday MIDNIGHT plan using the window scorecard. It governed 0.241 d with score/compliance 52.9, temp compliance 58.4%, VPD compliance 43.3%, heat stress 1.52 h, VPD-high 2.41 h, VPD-low 0.02 h, cold 0 h, and dew risk 0 h. The plan correctly preserved safety and avoided VPD-low/cold overshoot, but the moderate dry-edge posture did not deliver strong VPD recovery. The extreme Wednesday/Thursday forecast rationale remains pending and should be judged in later windows. Human score 4/10: safe and directionally correct, but weak corridor outcome. Score: 4/10

Hypothesis

Testing: Two-phase midnight reset: conserve through Tuesday pre-dawn and humid Tuesday night, but keep Wednesday/Thursday hot-dry wet/fog posture guardrail-clean instead of relying on dispatcher repairs. Expected outcome: For the next day: 0 dew-risk hours and 0 cold stress; Tuesday VPD-low under 0.5h overnight; Tuesday total water lower than Monday unless live VPD remains above band. For Wednesday/Thursday handoff: fewer VPD-high guardrail holds than the 350 held in iris-20260803-0602 while keeping fog/wet assist available during hot-dry VENTILATE.

Tuesday is cooler with a dry afternoon and a humid Tuesday-night recovery; Wednesday ramps hot/dry; Thursday becomes extreme near 100F, RH 5%, high solar. Forecast VPD has a known positive bias, so Tuesday is only moderate dry risk, while Wednesday/Thursday remain above the crop corridor even after discounting.

vpd_highhigh · 2026-08-06T07:00:00-06:00 to 2026-08-07T00:00:00-06:00

full hot-dry moisture posture with fog escalation 0.15, short effective duty, 300 gal practical cap, and delayed evening unwind while dew margin is safe

Parameter rationale

mister_engage_kpa0.82 → 1.27; current vpd_high is about 1.22 kPa; Tuesday corrected VPD is only moderately high, but Wednesday/Thursday dry windows remain above band

avoid the overnight over-wet posture while keeping first-stage moisture available near the high edge in dry windows without repeated guardrail repair

mister_all_kpa1.02 → 1.45; zone spread is small at midnight, Tuesday is moderate, and later hot/dry stress is broad whole-house

permit all-zone assist during confirmed broad dry stress while not forcing all-zone pulses pre-dawn

mister_pulse_gap_s30.0 → 35.0; Tuesday cooler afternoon needs moderate assist; Tuesday night VPD falls low while Thursday needs stronger duty

use duty taper by phase instead of carrying Monday peak misting through the humid night

fog_escalation_kpa0.2 → 0.15; Wednesday/Thursday VPD-high overlaps 07:00-17:00 fog-safe windows with dew margin currently 17F

make the 7x fog path available for hot-dry VENTILATE while holding it back during Tuesday pre-dawn and humid overnight recovery

mister_water_budget_gal200.0 → 300.0; Monday used 346 gal total with weak compliance, but Thursday extreme VPD should not be budget-limited when dew/occupancy rails are safe

avoid budget-limited extreme dry recovery while not spending extra water during Tuesday night taper

Today closed slightly above the seven-day score baseline but remained weak on corridor control: planner_score/compliance 66.7 versus 65.9 seven-day average, with legacy temp compliance 51.6% and VPD compliance 44.2%. VPD was the bottleneck and dominant stress was VPD-high at 9.75h, followed by heat at 7.79h; cold stress was 0 and VPD-low was only 0.06h. Dew safety held with dp_margin_min_f 8.9F and 0 dp-risk hours. Reliable cost fields are unavailable, so I am not using kWh/cost for decisions; water context is about 321 gal today versus 303 gal seven-day average, and 24h runtime was driven by cooling/wet-assist equipment: fan1/fan2 about 9.5h each, fog 6.3h, water flowing 6.1h, vent 3.5h. I evaluated iris-20260803-0201 at 4/10 versus deterministic anchor 3… Result: Evaluated the Tuesday SUNRISE plan using the window scorecard through sunset. It governed 0.588 d with score/compliance 44.7, temp compliance 49.3%, VPD compliance 36.6%, heat stress 3.13 h, VPD-high 4.97 h, VPD-low 0.03 h, cold 0 h, and dew risk 0 h. The hypothesis was right on safety and on VPD-high being the dominant risk, but corridor delivery was poor and guardrail audit still showed many clamped/held moisture settings. The plan’s moderate Tuesday assist and taper avoided wet overshoot but failed to materially improve VPD compliance. Human score 3/10: safe, but weak VPD/heat compliance and dirty materialization. Score: 3/10

Hypothesis

Testing: Guardrail-clean phased moisture: use moderate Tuesday assist, taper Tuesday night, then reopen stronger band-coupled fog/mist for Wednesday and Thursday dry heat without asking the dispatcher for values it will clamp. Expected outcome: Today: keep dew-risk at 0h, avoid VPD-low overshoot overnight, and keep Tuesday water below Monday while preserving dry-edge recovery. By Thursday: keep wet/fog assist available for the extreme dry event without repeating hundreds of VPD-high guardrail holds.

vpd_highhigh · 2026-08-06T07:00:00-06:00 to 2026-08-07T00:00:00-06:00

full hot-dry moisture surface with engage near +0.05, all-zone +0.20, fog 0.15, daily budget 300 gal, and late dry recovery while dew margin is safe

Parameter rationale

mister_engage_kpa0.95 → 1.27; active vpd_high is about 1.22 kPa and Wednesday/Thursday dry windows remain above band after bias discount

keep first-stage moisture available near the high edge without causing another guardrail-held conservative threshold pattern

mister_all_kpa1.14 → 1.44; dry stress broadens Wednesday and becomes extreme Thursday; Tuesday is only moderate

permit all-zone assist during broad dry stress while not forcing aggressive all-zone pulses during Tuesday dawn/taper

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

avoid sacrificing recovery capacity during real dry stress; conserve instead through mist duty limit and phase timing

fog_escalation_kpa0.3 → 0.18; Wednesday and Thursday VPD-high overlap fog-safe hours with dew margin currently 15.5F

make the 7x fog path available for confirmed hot-dry VENTILATE while holding it back Tuesday night

mister_water_budget_gal180.0 → 300.0; Monday used 346 gal and Thursday forecast is extreme; a 180 gal cap risks budget-limited VPD recovery

avoid budget-limited extreme dry recovery while using Tuesday's lower duty/resource settings to limit unnecessary water

direct_wet_stress_latest_hour21.0 → 22.0; Thursday evening stays very dry, while Tuesday night humidifies

allow bounded late dry recovery only in the dry windows while the Tuesday humid-night waypoint cuts wet posture earlier

Reflection

Validating previous cycle: iris-20260804-0603

Previous hypothesis: SUNRISE plan for Tuesday 2026-08-04. Monday was safe but not well-controlled: daily score 63.3 versus 65.9 7d average, temp compliance 49.7%, VPD compliance 41.8%, and VPD-high dominated at 12.54h versus heat at 10.18h. Cost fields remain unavailable; water was 346 gal total and 152 gal misting versus 303 gal 7d total-water average, so resource pressure is real but not allowed to close wet assist during safe VPD-high. I evaluated iris-20260803-2013 at 3/10 versus anchor 1: it preserved dew/cold safety but was a dirty materialization with 480 VPD-high guardrail events and 444 held, so today’s plan must reduce guardrail dependence rather than merely ask for conservative thresholds that get repaired. Current state is safe, cool-side, and dry-edge but not stressed: 68.7F, VPD 1.02 kPa, RH 58%, dew margin 15.5F, IDLE with heat1 on and wet/cooling off… Result: Evaluated the Tuesday SUNSET plan over its completed pre-midnight governed window and midnight state. Daily Tuesday closed weak at score/compliance 51.6 versus 64.6 seven-day average, with temp compliance 56.1%, VPD compliance 43.9%, 8.49 h heat stress, 11.09 h VPD-high stress, 0.83 h VPD-low, 0 cold, water 100 gal total / 33 gal misting, and dew safety preserved at dp_margin_min_f 8.7F with 0 dp-risk hours. The sunset plan’s overnight taper portion matched the immediate outcome: current 00:16 state is safe and quiet at 68.4F, VPD 0.61 kPa, RH 74%, dew margin 8.4F, IDLE, all climate/wet relays off, and no new safety alerts. The planned VPD-low risk was real: VPD is now just below the current low edge, so suppressing wet assist and holding fog back was appropriate. However the window scorecard section for iris-20260804-2012 reported zero compliance/stress values for the 0.167 d window, likely a scoring-data limitation rather than proof of perfect control, and guardrail audit still shows many clamps/held values from overly conservative moisture thresholds during live VPD-high context. Human score 5/10: good dew/cold safety and correct overnight wet taper, but incomplete/possibly invalid window score data and continued guardrail dependence limit confidence; the daylight hot/dry reopen hypothesis remains pending for today. Score: 5/10

New finding: On humidifying post-sunset nights after a hot/dry day, tapering wet assist can preserve dew safety and avoid cold/wet relay activity when live VPD is below the high edge, but if VPD is already near or below the low edge at midnight the next plan must reopen moisture based on forecast/live ramp timing rather than leaving conservative thresholds active into the first dry-edge window. → Added to Lessons Learned

Hypothesis

Testing: Overnight wet-taper then daylight reopen: avoid carrying daytime moisture aggression into a humid dawn, then reopen band-coupled wet/fog assist before the Wednesday hot/dry ramp. Expected outcome: By sunrise: dew-risk 0h, cold 0h, VPD-low under 1h, and no unnecessary wet relay cycling. By Wednesday evening: better VPD recovery than Tuesday with fewer guardrail-held conservative moisture requests.

Tuesday sunset is safe and near band with dew margin 12.7F. Overnight cools and humidifies strongly, creating VPD-low/dew/churn risk rather than dry-stress risk. Wednesday turns hot/dry by late morning with raw VPD above 3 kPa and corrected VPD still above corridor.

vpd_highhigh · 2026-08-05T11:00:00-06:00 to 2026-08-05T20:30:00-06:00

reopen guardrail-clean band-coupled moisture: engage near +0.05, all-zone near +0.22, fog escalation near 0.18 during fog-safe VENTILATE, and do not unwind until observed VPD recovers

heatmedium · 2026-08-05T13:00:00-06:00 to 2026-08-05T19:00:00-06:00

thermal lead, solar pre-cool, all-fan authority already enabled, and wet/fog assist while accepting physics-limited peak heat

Parameter rationale

mister_engage_kpa1.0 → 1.47; raw overnight VPD falls from 1.08 to 0.06 kPa and RH rises to 95% by dawn while live VPD is already below high band

avoid unnecessary overnight misting and VPD-low overshoot while maintaining dew safety

mister_all_kpa1.21 → 1.67; overnight zone spread is small and humidity will hold better while sealed

prevent all-zone pulses overnight unless a real dry-edge miss appears

fog_escalation_kpa0.24 → 0.45; fog is outside its normal time window overnight and the main risk is over-wet/churn

hold back the 7x fog path until the daytime dry ramp returns

mister_water_budget_gal250.0 → 120.0; resource optimization is allowed now because temp and VPD are in band and dew margin is healthy

reduce water/wear overnight without closing assist during actual band misses

mister_engage_kpa1.47 → 1.27; Wednesday corrected VPD rises above corridor after 11:00 with solar near 875 W/m2

restore first-stage moisture near the high edge before VPD-high dominates

fog_escalation_kpa0.45 → 0.18; Wednesday VPD-high overlaps fog-safe hours with live dew margin 12.7F

make fog available for hot-dry VENTILATE while firmware still enforces RH/temp/time safety gates
