Solar peak planning checkpoint	13:08	SOLAR_MAX	acked	Acknowledged: SOLAR_MAX no tactical change. Live solar is overshooting the 14:00 forecast (1014 W/m2 observed vs 888 W/m2 raw forecast, even after applying the small recent solar bias), but the active SUNRISE plan already has the hot-dry compliance-first posture materialized: fog_escalation_kpa 0.15, mister_engage_kpa 1.27 near vpd_high+0.05, mister_all_kpa 1.44, pulse gap 24s, pulse on 90s, direct wet stress override enabled, all-fans-at-high enabled, and dwell gate enabled... Resolved 13:09 MDT.
Peak Stress	15:08	TRANSITION	acked	Acknowledged: Peak-stress transition checked live climate, equipment, active plan, and setpoints. Conditions are severe but tracking the active hot-dry plan: temp 89.4F and VPD 1.89 kPa are above band with safe 13.8F dew margin; vent, both fans, and fog are already on in VENTILATE. Tactical posture is already near the hot-dry ladder floor (fog_escalation_kpa 0.15, mister_engage_kpa 1.25 near vpd_high+0.03, mister_all_kpa 1.44 near +0.22, pulse gap 22s, all-fans enabled, dwell enabled)... Resolved 15:08 MDT.
Forecast deviation	15:51	FORECAST_DEVIATION	acked	Acknowledged: FORECAST_DEVIATION assessed live. Observed VPD and solar are both lower than the raw forecast, matching the known positive VPD forecast bias and an early cloud/solar forecast error rather than a new hotter/drier regime or equipment failure. Live greenhouse still has temp and VPD above band, but the controller is already in VENTILATE with vent, both fans, and fog active under the existing aggressive hot-dry plan; dew margin is safe at about 13F. No additional tunable change needed. Resolved 15:51 MDT.
Forecast deviation	16:51	FORECAST_DEVIATION	acked	Acknowledged: FORECAST_DEVIATION no-op: observed VPD is lower than raw forecast by about 1.49 kPa, matching the documented positive VPD forecast bias (~+1.5 kPa) rather than indicating a new live weather regime. Current climate is still hot/dry-edge (85.2F, VPD 1.80 kPa, dew margin 16.6F) but equipment is already in the appropriate cooling/fog-assist posture with vent, fan1, fan2, and fog on; wet/fog safety rails are healthy.

Forecast deviation	17:36	FORECAST_DEVIATION	acked	Acknowledged: FORECAST_DEVIATION assessed: outdoor temperature is 91.4F versus forecast about 100F, but this is a cooler-than-forecast shift in the same direction as the known positive temperature forecast bias. Current house is in a safe/resource state at 83.5F, VPD 1.11 kPa, RH 71%, dew margin 10.1F, mode IDLE, and all climate relays/wet assist are off. No live controller-attributable heat or VPD miss requires a tactical tunable change. Resolved 17:37 MDT.
Forecast deviation	17:51	FORECAST_DEVIATION	acked	Acknowledged: FORECAST_DEVIATION no-op: live climate shows VPD 1.00 kPa, RH 74%, 82.1F, dew margin 9.2F, mode IDLE; all climate equipment is off. The reported VPD forecast overshoot is in the same direction as the known positive VPD forecast bias, so this is forecast calibration catching up rather than a live weather/equipment miss. No tunable change made. Resolved 17:51 MDT.
Forecast deviation	18:51	FORECAST_DEVIATION	acked	Acknowledged: FORECAST_DEVIATION assessed as forecast VPD positive-bias catching up, not a live weather or equipment regime change. Current climate is near the evening band: 82.8F, VPD 1.27 kPa, RH 67%, dew margin 12.0F, IDLE; all climate relays/fog/misters are off. Existing wet-assist posture remains appropriate, so no tunable change was made. Resolved 18:52 MDT.
Decline	19:26	TRANSITION	acked	Acknowledged: Decline transition checked live climate, equipment, active plan, and setpoints. Current house is still in safe hot/dry VPD-high recovery: 83.0F, VPD 1.51 kPa above 1.22 high edge, dew margin 14.7F, VENTILATE with both fans and fog assist active. Wet/fog assist is allowed and useful, while the existing plan already has a later 22:30 taper to higher thresholds, wider mist gap, and conservative fog escalation before the overnight handoff...

Reflection

Validating previous cycle: iris-20260719-0548

Previous hypothesis: SUNRISE plan for Sunday 2026-07-19. Yesterday scored 65.6, essentially flat against the 7-day average 65.7, but remained dual-axis limited: VPD was the bottleneck at 36.6% compliance versus 47.4% temp compliance, with 14.13h VPD-high stress and 11.09h heat stress. Dew safety held at dp_margin_min_f 8.8F and 0.0 dp-risk hours, so the correct response is not moisture suppression. I evaluated the completed sunset plan iris-20260718-2029 at 4/10; plan_evaluate anchored it at 2 because 602 VPD-high guardrail events and 568 held-by-guardrail events show the plan was materially guardrail-shaped. The self-score is higher than the anchor only because the plan preserved safety, not because it recovered the corridor. Current state is safe and low-side: 70.5F, VPD 0.88 kPa, RH 66%, dew margin 12F, IDLE, all relays off. Today is forecast extreme hot/dry: 98F raw high, RH 15-16%, raw VPD up to 5… Result: Evaluated at Monday SUNRISE using the available scoped window before the weekly plan superseded it. The plan governed a short overnight/pre-dawn window (~0.073 day). Scoped score/compliance was 83.5 with temp compliance 39.5%, VPD compliance 28.3%, about 0.24h heat stress and 0.29h VPD-high stress, 0.0h cold stress, 0.0h VPD-low stress, and dew safety preserved. Daily/yesterday context remains much weaker: Sunday scored 69.8 with VPD the bottleneck at 34.8% versus temp 46.2%, 14.66h VPD-high and 11.27h heat, water 403 gal total / 196 gal misting-only versus 347 gal 7d average. The short window validates dew-safe overnight continuity, not daytime corridor recovery. Retrieval was attempted for this sunrise but knowledge_search and lessons_search are blocked by missing OPENAI_API_KEY, so evidence comes from MCP scorecards/context and static lessons. Score: 7/10

Hypothesis

Testing: Guardrail-compatible MIDNIGHT reset for an extreme hot-dry Monday: preserve a modest dew-safe overnight surface, reopen band-coupled wet/fog assist before sunrise, then taper only after live dry-edge recovery or the Tuesday-night humid handoff. Expected outcome: Keep dew-risk and VPD-low stress at 0h while reducing Monday VPD-high severity versus Sunday; accept physics-limited heat near 101F outdoors, and watch whether bounded ClimateIntent reduces guardrail-held wet-assist rows compared with iris-20260719-0548.

vpd_highmedium · 2026-07-20T00:15:00-06:00 to 2026-07-20T05:30:00-06:00

preserve a modest dew-safe overnight wet-assist surface without peak daytime water duty; reopen more aggressively before sunrise

vpd_highhigh · 2026-07-20T07:30:00-06:00 to 2026-07-20T22:00:00-06:00

band-coupled wet assist: engage near vpd_high+0.05, all-zone near +0.20 to +0.25, daylight fog escalation near 0.15, low resource sensitivity while dew margin stays healthy

early thermal lead and solar precooling with all-fans cooling plus vent-mist/fog assist; accept structural peak heat rather than chasing target-line errors

vpd_lowhigh · 2026-07-22T20:00:00-06:00 to 2026-07-23T00:30:00-06:00

suppress low-value wet assist and preserve dew safety during the forecast storm/humid evening

Parameter rationale

mister_engage_kpa0.82 → 1.27; current VPD is below the 1.22 kPa high edge but raw VPD exceeds 2 kPa by 08:00 and reaches 5+ kPa during peak heat

make S1 wet assist available near the dry edge when live VPD rises, without relying on dispatcher guardrail correction

mister_all_kpa1.02 → 1.47; zone VPD spread remains >0.5 kPa and Sunday VPD compliance was only 34.8% daily / 28.9% in the validated plan window

allow all-zone escalation during meaningful hot-dry stress while keeping a wider deadband for localized spread

fog_escalation_kpa0.2 → 0.15; the 07:00-17:00 fog window overlaps Monday's extreme hot-dry ramp and dew margin is 12.4F with 0h dp-risk

enable daylight vent-fog assist before severe VPD-high error accumulates

mister_pulse_gap_s30.0 → 22.0; forecast RH falls to 14-20% with solar near 879 W/m2 and recent VENT_COOL_MIST_ASSIST improved VPD error slightly

increase useful wet duty during VENTILATE while avoiding a clock-only evening unwind before measured recovery

mister_water_budget_gal300.0 → 300.0; water was high at 403 gal, but VPD remains the limiting axis and dew risk is zero

avoid budget-limited recovery during safe extreme dry stress; conserve by tapering after recovery rather than lowering the cap

direct_wet_stress_latest_hour21.0 → 22.0; VPD-high is forecast to persist into Monday evening and the prior 22:00 request missed materialization

permit bounded evening dry-edge recovery through 22:00 if dew margin remains above 8F, while explicitly watching for another missed materialization

Validating previous cycle: iris-20260719-0548

Result: Evaluated at Monday SUNSET before writing the overnight plan. The weekly plan governed only a short 0.158 day window before the sunrise plan superseded it. Scoped window score was 73.2, with temp compliance 46.8% and VPD compliance 33.7%; stress remained dual-axis with about 1.49h heat stress and 1.97h VPD-high stress in the short window, while cold stress, VPD-low stress, and dew risk stayed at 0. The plan direction matched the hot-dry diagnosis and preserved safety, but the short window is not proof of daytime corridor recovery and VPD remained the limiting axis. Score: 5/10

Hypothesis

Testing: Weekly posture test: compare guardrail-compatible ClimateIntent against the last week of hot-dry plans; success is fewer guardrail-held wet-assist rows while preserving dew safety and reducing VPD-high severity during the next two dry ramps. Expected outcome: Over the next 72h: keep dp_risk_hours at 0, VPD-low stress near 0 except the forecast storm period, avoid worsening water beyond the Sunday 403 gal total, and improve or hold VPD-high severity versus the 7-day baseline while accepting physics-limited peak heat.

band-coupled moisture near vpd_high+0.05, all-zone near +0.20 to +0.25, fog escalation near 0.15-0.18 during the daylight fog window, low resource sensitivity while dew margin is healthy

vpd_lowhigh · 2026-07-22T20:00:00-06:00 to 2026-07-23T01:59:00-06:00

suppress low-value wet assist, raise dew margin floor, and prioritize disease/dew safety during storm humidity

Parameter rationale

mister_engage_kpa0.79 → 1.27; VPD-high dominated all seven days at about 14h/day and Monday corrected priors still exceed the high edge from morning through evening

keep S1 wet assist available at the band edge during safe dry stress without relying on dispatcher correction

mister_all_kpa1.0 → 1.47; zone VPD spread is >0.5 kPa and dry stress persists despite high water use

allow all-zone mist only when dry stress is meaningful, while preserving a wider deadband for localized spread

fog_escalation_kpa0.2 → 0.15; daylight fog window overlaps Monday and Tuesday severe dry ramps with dew margin currently >15F and 0h dp-risk last week

use fog as severity mitigation during peak VENTILATE rather than increasing mister duty alone

mister_pulse_gap_s30.0 → 22.0; Monday RH falls to 12-14% with solar near 882 W/m2 and previous hot-dry days stayed VPD-limited

increase useful wet duty during peak hot-dry ventilation, then taper before humid storm periods

mister_water_budget_gal300.0 → 300.0; Sunday used 403 gal total and 196 gal misting-only, but dew safety held and VPD remained the limiting axis

avoid budget-limited recovery during safe peak dry stress while saving water via time-of-day taper instead of lowering the cap

direct_wet_stress_latest_hour21.0 → 22.0; Monday evening remains hot and dry, but Tuesday and Wednesday evenings turn humid/stormy

permit bounded Monday dry-edge recovery while cutting wet assist earlier on humid handoff nights

Previous hypothesis: SUNSET overnight plan for Sunday 2026-07-19. Today scored 68.3 versus 66.5 7-day average, so slightly better than the recent baseline, but it remains a dual-axis hot-dry limitation: VPD is still the bottleneck at 36.5% compliance versus 48.9% temp compliance, with 11.76h VPD-high stress and 8.64h heat stress. Dew safety held at dp_margin_min_f 9.1F and 0.0 dp-risk hours; current air is safe at about 81.3F, VPD 1.21 kPa, RH 67%, dew margin 11.9F, IDLE, but east remains a dry planted outlier near 1.50 kPa and zone spread is large. Cost terms are unavailable/resource weight 0, so I am using water/wear context instead: total water is trending high at 364 gal today versus 347 gal 7-day average, with heavy fog/water-flow cycling… Result: Sunrise plan daily outcome for 2026-07-20: daily score 74.1 versus 66.8 7-day average, but corridor recovery remained structurally limited. VPD was the bottleneck at 32.4% compliance versus temp 44.6%; dominant stress was VPD-high 15.39h, with heat also severe at 12.02h. Cold stress and VPD-low were 0.0h, and dew safety held with dp_margin_min_f 9.0F and dp_risk_hours 0.0. Forecast diagnosis was broadly correct for an extreme hot-dry day: actual outdoor peak was about 101.6F and solar exceeded the forecast at about 1018 W/m2. Wet/fog assist preserved dew safety and likely reduced severity, but did not achieve the hoped-for VPD corridor recovery under physics-limited heat/solar; recent guardrail/held events show materialization was still guardrail-shaped. Total water was 405 gal and misting-only 194 gal versus 355 gal 7-day total-water average; resource cost fields were unavailable, so water/wear are context rather than scored cost. Score: 4/10

Hypothesis

Testing: Guardrail-clean hot-dry severity-mitigation test: use bounded ClimateIntent values that should materialize cleanly, then compare guardrail-held wet-assist rows and VPD-high severity against Sunday/Monday baselines. Expected outcome: Dew safety remains at 0 dp-risk hours; Monday VPD-high remains the bottleneck but severity is reduced versus Sunday if wet assist materializes, with fewer held-by-guardrail events than the previous midnight/weekly plans.

short renewed dry-stress posture before storm humidity; early cutoff to avoid Wed evening VPD-low/dew risk

Parameter rationale

mister_engage_kpa0.95 → 1.27; live VPD is below high edge at dawn but forecast dry ramp exceeds corrected high-edge priors by 08:00-09:00

keep S1 wet assist available near vpd_high+0.05 during live VPD-high without relying on dispatcher guardrail correction

mister_all_kpa1.14 → 1.47; yesterday had 14.66h VPD-high stress and zone VPD spread recently reached about 0.66 kPa

allow all-zone rotation only during meaningful dry stress while preserving a wider deadband for localized spread

fog_escalation_kpa0.2 → 0.15; fog window overlaps the 10:00-17:00 extreme dry ramp and dew margin is 13.8F with no dp-risk yesterday

enable daylight vent-fog assist before severe VPD-high error accumulates

mister_pulse_gap_s30.0 → 22.0; RH falls to 14-18% with solar near 881 W/m2 and recent VPD compliance stayed near 35% despite high water

increase useful wet duty during peak VENTILATE, then taper with evening and next-day humid cutoffs

mister_water_budget_gal300.0 → 300.0; water was high at 403 gal, but VPD remained the limiting axis and dew safety held

avoid budget-limited dry-stress recovery during safe peak stress while conserving by time-of-day posture

direct_wet_stress_latest_hour21.0 → 22.0; Monday evening remains hot and dry with forecast VPD above 3 kPa after sunset

permit bounded Monday evening dry-edge recovery while cutting earlier ahead of Tuesday/Wednesday humid handoffs

Previous hypothesis: SUNRISE plan for Monday 2026-07-20. Yesterday scored 69.8 versus 66.5 7-day average, but was still structurally hot/dry limited: VPD compliance was the bottleneck at 34.8% versus temp compliance 46.2%, with 14.66h VPD-high stress and 11.27h heat stress. Water was high at 403 gal total / 196 gal misting-only versus 347 gal 7-day average, while dew safety held at dp_margin_min_f 9.1F and 0.0 dp-risk hours. I evaluated the completed midnight plan iris-20260720-0016 at 7/10; deterministic anchor was 5 because 160 VPD-high guardrail events, mostly held-by-guardrail, mean that short overnight window preserved safety but was still materially guardrail-shaped. Current house is safe: about 72.5F, VPD 1.04 kPa, RH 62%, dew margin 13.8F, VENTILATE with vent and both fans on, wet/fog currently below threshold… Result: Evaluated at the Tuesday MIDNIGHT reset using the scoped window the sunset plan governed before replacement. The window score was 100.0 with 0.00h heat stress, 0.00h VPD-high stress, 0.00h cold stress, 0.00h VPD-low stress, and dew safety intact; live air at review is safe at about 76.4F, VPD 1.08 kPa, RH 65%, and dew margin 12.3F. The prior full Monday day was still structurally limited at score 74.1, temp compliance 44.6%, VPD compliance 32.4%, 12.02h heat stress, 15.39h VPD-high stress, 405 gal total water, and dp_risk_hours 0.0. The sunset hypothesis was correct for the overnight segment: tapering after solar load preserved safety and avoided VPD-low/dew risk. It is not yet evidence for the Tuesday daytime reopening and humid-handoff predictions, and recent audit rows still show guardrail-held and missed tactical values, so the score is below perfect despite the zero-stress scoped window. Score: 8/10

New finding: On warm post-extreme hot-dry evenings, a guardrail-compatible overnight taper can keep the house inside the served corridor with zero dew/VPD-low stress when dew margin starts above 10F; however, daytime hot-dry recovery and humid-handoff suppression must be evaluated separately, and plans should avoid requesting values the VPD-high guardrail will immediately hold or rewrite. → Added to Lessons Learned

Hypothesis

Testing: Guardrail-compatible sunset taper: preserve evening VPD recovery while reducing overnight water/churn, then reopen before Tuesday dry ramp and cut before humid/rain handoff. Expected outcome: Overnight: 0h cold and VPD-low stress, dp_risk_hours 0, dew margin >8F, and lower overnight water/churn than daytime. Tuesday morning handoff should enter the dry ramp with VPD near band and wet/fog assist available without repeating large guardrail-held corrections.

cut wet duty earlier and raise dew-margin caution as forecast rain/RH arrives

Parameter rationale

mister_engage_kpa1.0 → 1.27; current VPD is near the high edge with east dry at 1.37 kPa and raw overnight VPD remains high, but dew margin is safe

allow evening dry-edge recovery near vpd_high+0.05 without closing the wet surface while VPD stress is active

mister_all_kpa1.2 → 1.47; zone VPD spread is large and VPD-high dominated today, but water/churn was high

permit all-zone escalation only when dry stress is meaningful, then taper overnight rather than all-night high duty

mister_pulse_gap_s30.0 → 45.0; solar is absent overnight and humidity holds better when sealed; no VPD-low or dew risk occurred today

reduce low-value overnight water/relay churn while preserving a controlled evening and pre-dawn recovery path

fog_escalation_kpa0.2 → 0.18; Tuesday daylight fog window overlaps another 95-97F dry ramp; Monday fog/wet assist improved severity but not full compliance

make fog available as Tuesday severity mitigation without relying on night fog, which firmware blocks

mister_water_budget_gal300.0 → 300.0; water was above recent average but VPD remained the limiting axis and dew safety held

avoid budget-limited recovery during safe dry stress while conserving by overnight duty taper and humid-handoff cutoff
