Forecast deviation	18:05	FORECAST_DEVIATION	acked	Acknowledged: FORECAST_DEVIATION reviewed: observed VPD is lower than raw forecast in the same direction as the known positive VPD forecast bias, while live controller already has vent, both fans, and fog assist active with dew margin safe.

Decline	19:27	TRANSITION	acked	Acknowledged: TRANSITION decline no tunable change: current temp 82.7F is inside/near served sunset band, VPD 1.32 kPa remains above vpd_high 1.22 with east/west dry outliers, dew margin is safe at 12.6F and equipment is already sealed/off after recent fog. The active plan already contains an evening taper waypoint at 21:30; raising mist/fog thresholds now would prematurely close wet assist during live VPD-high recovery before observed VPD is below band.

Reflection

Validating previous cycle: iris-20260718-0547

Previous hypothesis: SUNRISE plan for Saturday 2026-07-18. Yesterday scored 67.2, above the 7-day average 64.2, but it remained strongly VPD/heat limited: temp compliance 48.4%, VPD compliance 35.1%, 10.69h heat stress and 14.53h VPD-high stress, no cold or VPD-low stress, and dew safety held at dp_margin_min 8.8F / dp_risk_hours 0.0. Water was 350 gal versus 343 gal 7-day average, with 143 gal misting-only; resource cost terms are incomplete, so today’s resource constraint is water/wear, not trusted energy cost. I evaluated the completed sunset plan iris-20260717-2028 at 4/10; plan_evaluate returned anchor 2 because 408 guardrail events and 360 held-guardrail events mean that plan was materially reshaped. I accept the anchor warning: recent plans are safe severity-reduction attempts, not clean recovery experiments. Current house is safe and in the low-side morning corridor at about 70.1F, VPD 0… Result: Validated during the SUNSET cycle using the scoped window scorecard. The midnight reset preserved safety but did not materially recover the crop corridor: scoped window score/compliance was 68.3 with temp compliance 48.9% and VPD compliance 36.5%; stress during governance was about 2.00h heat and 2.72h VPD-high with 0.0h cold and 0.0h VPD-low. Dew safety remained good with dp_margin_min_f about 9.1F and 0.0 dp-risk hours. The forecast/stress diagnosis for an extreme hot-dry sequence was right, but the wet/fog posture should be treated as guardrail-shaped severity mitigation rather than a clean recovery experiment; repeated missed/guardrailed values mean future plans should request bounded ClimateIntent values that materialize cleanly and avoid relying on dispatcher correction. Score: 4/10

Hypothesis

Testing: Guardrail-compatible extreme hot-dry severity mitigation: request band-coupled wet/fog assist values directly and judge success by VPD-high hours versus the recent July baseline, not by target-line hugging. Expected outcome: For the new day, keep dew-risk hours at 0 and VPD-low stress at 0 while accepting structural heat stress; reduce VPD-high severity versus the last 7-day pattern if live dew margin remains above 8F, and avoid another plan dominated by guardrail-held wet-assist materializations.

early thermal lead and solar precooling, all fans at high, preserve vent-mist/fog assist, and accept structural peak heat rather than target hugging

vpd_highhigh · 2026-07-20T08:00:00-06:00 to 2026-07-20T22:00:00-06:00

repeat compliance-first wet assist for the hotter Monday ramp; do not unwind until measured VPD is below the served high edge

vpd_lowmedium · 2026-07-21T22:00:00-06:00 to 2026-07-22T00:15:00-06:00

taper wet/fog intensity and raise dew margin caution as late Tuesday forecast RH rises toward the Wednesday cool/humid handoff

Parameter rationale

mister_engage_kpa0.82 → 1.27; live VPD is already near the 1.22 kPa high edge and Sunday raw VPD exceeds 2 kPa by 09:00 with corrected priors still severe

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

mister_all_kpa1.02 → 1.42; east is the planted dry outlier and recent VPD compliance was only 36.6% daily / 30.4% in the validated plan window

allow all-zone escalation near vpd_high+0.20 during hot-dry ventilation while preserving the wider deadband for zone spread

fog_escalation_kpa0.2 → 0.15; fog window overlaps the 09:00-17:00 hot-dry ramp and current dew margin is 15F with no dp-risk hours

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

mister_pulse_gap_s30.0 → 22.0; solar near 890 W/m2 and RH near 14-16% through peak stress

maintain useful wet duty during peak ventilation, then taper after sunset to avoid water and relay churn

mister_water_budget_gal300.0 → 300.0; Saturday used 359 gal total and 162 gal misting-only but VPD remained the limiting axis with dew safety intact

avoid budget-limited VPD recovery during safe extreme dry stress while conserving with tapering rather than a lower cap

direct_wet_stress_latest_hour21.0 → 22.0; VPD-high is forecast to persist into the evening while dew margin is presently healthy

permit bounded evening dry-edge recovery through 22:00 when dew margin remains above 8F

Validating previous cycle: iris-20260718-2029

Previous hypothesis: SUNSET overnight plan for Saturday 2026-07-18. Today scored 66.4, slightly above the 7-day average 65.7, but VPD remained the bottleneck: temp compliance 50.0% vs VPD compliance 38.7%, with 11.23h VPD-high stress and 8.51h heat stress, no cold or VPD-low stress, and dew safety intact at dp_margin_min 8.8F / dp_risk_hours 0.0. Resource cost terms are unavailable, so I am reading water/wear instead: total water was 329 gal vs 345 gal 7-day average, while fog ran 6.34h and water-flow cycling was high. The completed midnight reset iris-20260718-0017 was evaluated at 5/10; plan_evaluate anchored it at 3 because 763 guardrail events and 735 held-by-guardrail events show it was a safe guardrail-shaped handoff rather than a clean recovery experiment. Current house is safe at 81.1F, VPD 1.10 kPa, RH 71%, dew margin 10.5F, IDLE, but east remains the dry outlier near 1… Result: Validated at MIDNIGHT using the scoped window scorecard for 2026-07-19. The forecast diagnosis was directionally right: outdoor temp peaked 98.7F versus 98F predicted, solar was even harsher at 1024 W/m2 versus 886 predicted, and the dominant stress types matched the hypothesis. Safety goals were met: 0.0h cold stress, 0.0h VPD-low stress, dp_margin_min_f 9.1F, and 0.0 dp-risk hours. The plan missed the recovery goal: the governed window scored 58.0 with temp compliance 38.4% and VPD compliance 28.9%, with 5.71h heat stress and 7.43h VPD-high stress. Daily score was 69.8, slightly above 7-day average, but water was high at 403 gal total and 196 gal misting-only, while VPD remained the bottleneck. Rationale grading: band-coupled mist/fog values preserved safety but did not overcome extreme solar/heat capacity limits; fog/mist assist acted as severity mitigation, not clean corridor recovery. The Monday-forward stress windows remain valid, but the previous values were repeatedly guardrail-shaped and should be requested through bounded ClimateIntent values that materialize cleanly instead of relying on correction. Score: 4/10

New finding: On extreme July hot-dry days with solar near or above 1000 W/m2 and outdoor highs near 100F, band-coupled mist/fog assist with fog escalation near 0.15 and short pulse gaps should be treated as severity mitigation unless the scoped window shows VPD compliance improvement; safety may hold while corridor recovery still fails, especially when guardrails materially reshape requested wet-assist values. → Added to Lessons Learned

Hypothesis

Testing: Guardrail-compatible extreme hot-dry severity mitigation: request wet/fog assist values directly inside bounded ClimateIntent and judge success by VPD-high hours below the recent 14h July baseline with dew-risk remaining zero. Expected outcome: Today should preserve dew safety at 0 dp-risk hours, avoid cold and VPD-low stress, and reduce VPD-high severity versus recent hot-dry baseline if fog/mist assist materializes; heat stress will likely remain structural around peak outdoor 98F.

vpd_highhigh · 2026-07-19T08:00:00-06:00 to 2026-07-19T22:00:00-06:00

keep wet assist band-coupled near the VPD high edge, use all-zone escalation near +0.20 to +0.25 kPa, daylight fog escalation near 0.15 kPa, and keep resource sensitivity low while dew margin stays healthy

heathigh · 2026-07-19T10:30:00-06:00 to 2026-07-19T20:00:00-06:00

early thermal lead and solar precooling with vent/fan cooling plus vent-mist/fog assist; accept structural peak heat instead of chasing target-line errors

vpd_highhigh · 2026-07-20T08:00:00-06:00 to 2026-07-20T22:00:00-06:00

repeat compliance-first wet assist for Monday extreme heat, low resource sensitivity, no clock-only unwind before observed VPD recovery

vpd_lowmedium · 2026-07-21T22:00:00-06:00 to 2026-07-22T05:30:00-06:00

taper wet/fog intensity and raise dew margin caution as forecast shifts toward cloudy/humid overnight conditions

Parameter rationale

mister_engage_kpa1.27 → 1.27; live VPD is safe at dawn but forecast VPD exceeds 2 kPa by 09:00 and recent VPD compliance was only 36.6%

keep S1 wet assist available near vpd_high+0.05 without relying on dispatcher guardrail correction

mister_all_kpa1.47 → 1.42; VPD-high dominated yesterday and planted east remains the dry-side zone while solar approaches 900 W/m2

make all-zone rotation available near vpd_high+0.20 during hot-dry ventilation

fog_escalation_kpa0.25 → 0.15; the 07:00-17:00 fog window overlaps the dry ramp and dew margin is currently 12F

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

mister_pulse_gap_s41.25 → 22.0; forecast RH falls to 15-16% with solar near 886 W/m2 during peak heat

increase useful wet duty during VENTILATE without changing crop bands, then taper at night

mister_water_budget_gal300.0 → 300.0; Saturday water was 359 gal versus 345 gal average but VPD remained the limiting axis and dew risk was zero

avoid budget-limited recovery on a safe extreme dry day while conserving by evening taper rather than lowering the cap

direct_wet_stress_latest_hour21.0 → 22.0; VPD-high is forecast to persist after sunset and the prior 22:00 request did not materialize

permit bounded evening dry-edge recovery through 22:00 if dew margin remains above 8F and verify materialization

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: Weekly review evaluation using the available scoped window row before superseding with the weekly plan. The plan governed about 0.160 day overnight and currently shows a strong scoped score/compliance of 95.9, with only about 0.15h heat stress and 0.17h VPD-high stress, 0.0h cold stress, 0.0h VPD-low stress, and dew safety preserved. This is a short overnight window, so it is not proof that the daytime wet/fog posture recovers the corridor; it does validate that tapering overnight did not create condensation or low-VPD overshoot before Monday’s severe ramp. Current partial Monday data remains dominated by upcoming forecast risk, so keep the lesson narrow. Score: 7/10

New finding: On warm dry overnight handoffs before an extreme hot-dry day, a tapered moisture posture can preserve dew safety and avoid VPD-low overshoot, but a short high-scoring overnight window should not be extrapolated to daytime corridor recovery. → Added to Lessons Learned

Hypothesis

Testing: Dew-safe sunset taper before extreme Monday: reduce overnight water/churn without losing east dry-edge recovery, then reopen band-coupled wet/fog assist before sunrise. Expected outcome: Overnight dew-risk remains 0h, VPD-low remains 0h, and Monday pre-ramp wet assist materializes without the large VPD-high guardrail held pattern seen in iris-20260719-0015.

vpd_highmedium · 2026-07-19T20:25:00-06:00 to 2026-07-19T22:30:00-06:00

keep band-coupled wet assist available through the evening dry-edge recovery window while dew margin remains above 8F

vpd_highmedium · 2026-07-19T22:30:00-06:00 to 2026-07-20T05:30:00-06:00

taper duty and raise resource/churn caution overnight; humidity should hold better without solar, but raw outdoor VPD remains dry

vpd_highhigh · 2026-07-20T07:30:00-06:00 to 2026-07-20T20:30:00-06:00

reopen compliance-first wet assist before the ramp: 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 is safe

heathigh · 2026-07-20T10:00:00-06:00 to 2026-07-20T20:00:00-06:00

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

Parameter rationale

mister_engage_kpa1.0 → 1.27; current VPD is right at the 1.22 kPa high edge, east is near 1.50 kPa, and Monday raw VPD exceeds 2 kPa by 08:00

preserve dry-edge recovery tonight and keep S1 wet assist available near vpd_high+0.05 before Monday's ramp

mister_all_kpa1.21 → 1.47; zone VPD spread is about 0.7 kPa now and VPD-high was the dominant stress today at 11.76h

allow all-zone recovery when the dry edge is meaningful while tapering duty after solar is gone

mister_pulse_gap_s26.25 → 45.0; solar is absent overnight and water/relay cycling were high today

reduce low-value overnight churn while preserving a lower effective gap again at pre-dawn/morning ramp

fog_escalation_kpa0.2 → 0.15; Monday fog window overlaps 08:00-17:00 hot-dry ramp with dew margin currently 11.9F and dp-risk 0h

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

mister_water_budget_gal300.0 → 300.0; water is above the 7-day average but VPD remains the limiting axis and dew safety is intact

avoid budget-limited recovery during safe extreme dry stress while conserving overnight by duty posture rather than lowering the cap
