Previous hypothesis: SUNRISE plan for Wednesday 2026-07-22. Yesterday scored 66.9 versus the 68.1 seven-day average. VPD was the bottleneck at 40.1% compliance versus temp 45.6%; stress was dual-axis but VPD-high led at 12.86h, with 11.52h heat stress, 0.20h VPD-low, no cold stress, dp_margin_min 7.7F and zero dp-risk hours. Water was 342 gal total / 136 gal mister, below the 363 gal seven-day average, so resource use improved but corridor recovery did not. I evaluated iris-20260721-0550 at 5/10 versus deterministic anchor 2; the gap is because I credit correct safety diagnosis, lower water, and avoided dew/VPD-low overshoot, while the anchor correctly penalizes 776 VPD-high guardrail events and 660 held events showing the wet-assist surface still did not materialize cleanly… Result: Evaluated before the 2026-07-23 SUNSET plan using the plan-scoped window row. The plan governed the post-midnight/pre-dawn period and achieved a window score near 59.7, temp compliance 50.0%, VPD compliance 47.2%, and about 1.95h total stress during the scoped 5.6h window. Stress was mostly heat/temperature-band pressure at about 1.46h with about 0.58h VPD-high and no cold or VPD-low in the scoped row. Dew safety remained good: the daily scorecard shows dp_margin_min_f 6.9F and 0 dp-risk hours. The plan correctly avoided overnight dew risk and did not create a VPD-low excursion, but the action audit still showed guardrail holds/misses and the posture did not materially lift compliance over baseline. Conditions later proved cooler/more humid than severe dry-ramp forecasts, so the dry-assist hypothesis should be judged by materialized assist and live VPD confirmation rather than requested water budget alone. Score: 5/10

New finding: For humid overnight periods before a severe hot-dry forecast, score the overnight plan on dew safety, VPD-low avoidance, and materialized morning assist separately; aggressive next-day wet-assist requests should remain live-confirmed because forecast dry ramps can overstate VPD while solar still exceeds forecast. → Added to Lessons Learned

Hypothesis

Testing: Midnight reset: keep wet/fog surface guardrail-compatible during a humid dawn and Thursday dry pockets, then stage aggressive but bounded wet/fog assist ahead of Friday/Saturday severe heat/VPD without chasing in-corridor target lines. Expected outcome: By Thursday sunrise: dp_margin_min_f stays >=7F and no dp-risk while VPD-low stress remains minimal. During Thursday dry pockets: reduce VPD-high severity without all-day water spend. Friday/Saturday: accept physics-limited heat but keep VPD assist available near the high edge with fewer guardrail-held wet-assist requests than iris-20260722-0551.

Conditions

Thursday starts warm and humid with VPD-low/disease risk limited by a 10.3F dew margin, then has short dry pockets near midday/evening. Friday is severe hot-dry near 98F and 17% RH with VPD above 5 kPa; Saturday may reach 102F with solar near 900 W/m2, a physics-limited heat day.

Validating previous cycle: iris-20260722-2024

Previous hypothesis: SUNSET overnight plan for Wednesday 2026-07-22. Today scored 63.9 versus a 67.7 seven-day average, so performance was worse than baseline. VPD was only slightly worse than temperature as the compliance bottleneck (VPD 48.7% vs temp 50.9%), but the stress mix was dual-axis: heat led at 8.16h, VPD-high was 5.23h, and VPD-low rose to 2.97h after the humid handoff. Cost fields are unavailable/resource weight is 0, so I used water and runtime context instead: current context shows 147 gal total water today versus a 360 gal seven-day average, with high vent/fan/fog cycling; this saved water but did not lift the score. Dew safety held with dp_margin_min_f 7.0F and 0.0 dp-risk hours; current dew margin is 7.9F… Result: Evaluated during the 2026-07-24 MIDNIGHT cycle using the plan-scoped window row for the period it governed on 2026-07-23. The scoped window score was 62.1 versus the day’s 58.8 and 7-day baseline near 66.7; temp compliance was 47.4% and VPD compliance 46.4%. Scoped stress totaled 5.39h: heat 3.53h, VPD-high 1.78h, no cold stress, and no VPD-low stress. Dew safety held with daily dp_margin_min_f 6.9F and 0 dp-risk hours. The structured forecast was badly high/dry-biased for Thursday: predicted outdoor peak 102F and RH 13%, while actual peak was about 84.7F with indoor-proxy RH near 59%; solar exceeded prediction. Stress-window grading: the dawn VPD-low mitigation succeeded; the late-morning VPD-high window partly matched at medium severity; the afternoon/evening VPD-low/storm-handoff concern did not materialize as VPD-low; the 07-24/07-25 severe windows were future-facing and not scored in this completed window. Rationale grading: guardrail-compatible wet assist did not create VPD-low and dew risk, but it also did not materially lift temp/VPD compliance; full water-budget rationale was not proven because the dry ramp was far weaker than forecast; fog/short-gap rationale remains unproven for the later severe window. Overall: safe and directionally correct on VPD-low avoidance, weak on compliance lift, and materially affected by forecast overstatement and guardrail materialization uncertainty. Score: 5/10

New finding: When a humid dawn is followed by a forecast severe dry ramp with recent VPD forecast overstatement, separate safety scoring from dry-assist scoring: keep wet assist guardrail-compatible, but require live dry-ramp confirmation before crediting large water budget/fog hypotheses as successful. → Added to Lessons Learned

Hypothesis

Testing: Guardrail-compatible live-confirmed wet assist: restrain during Thu too-wet dawn/storm periods, then use moderate Thu and aggressive Fri/Sat band-coupled moisture/fog only when VPD is actually above band and dew gates are safe. Expected outcome: Thu should avoid dew-risk and reduce the current too-wet alert by the morning ramp, while keeping Thu VPD-high stress under ~2h. Fri/Sat will remain heat-limited, but aggressive wet/fog assist should reduce VPD-high severity versus recent 7-15h VPD-high days without increasing dp-risk above 0h.

Conditions

Thu begins humid/too-wet with Vanda drying alert, then a short dry pocket near 10:00-13:00 before storm/humid handoff. Fri and Sat become severe hot-dry physics-limited days, peaking near 99-102F with RH 13-17% and VPD 5-6 kPa.

Validating previous cycle: iris-20260723-0552

Previous hypothesis: SUNRISE plan for Thursday 2026-07-23. Yesterday closed below baseline at planner score 59.6 versus a 67.7 seven-day average. Temperature and VPD were essentially tied as bottlenecks (48.1% temp, 48.0% VPD), with stress dominated by heat at 10.72h, then VPD-high at 7.09h and VPD-low at 2.99h. Water use was sharply below average (148 gal total / 19 gal mister vs 360 gal 7-day average), so conservation happened but corridor recovery did not. Dew safety held at dp_margin_min_f 7.0F and 0 dp-risk hours. I evaluated iris-20260722-2024 at 6/10, but the deterministic anchor was 3 because 399 VPD-high guardrail events and 367 held guardrail events show materialization still diverged from requested posture; I credit the scoped evening window’s safety and modest stress, while the anchor correctly penalizes guardrail-heavy action proof… Result: Evaluated at 2026-07-24 SUNRISE before replacement. In its scoped overnight window the plan produced a 76.3 window score, with temp compliance 46.7% and VPD compliance 38.4%. Stress was low in absolute hours (about 0.45h total in the plan-scoped rollup), and dew safety held: daily dp_margin_min_f was 6.9F with 0 dp-risk hours. However the house drifted too wet versus the commanded VPD band overnight, triggering orchid-drying alerts around 00:56 and 01:56; current dawn air was 68.4F, VPD 0.44 kPa, RH 81%, dp margin 5.9F, all equipment off. The severe dry-ramp part of the hypothesis was future-facing and not gradeable in this completed window. Overall: safe and low-stress, but incomplete Vanda drying/VPD-low correction and no proof yet for the hot-dry wet-assist hypothesis. Score: 6/10

New finding: For humid nights before a severe hot-dry day, wet/fog restraint alone may not raise VPD enough for Vanda drying even when dew safety holds; pair the restraint with active dehumidification/economizer posture and track house_band_drift alerts as a first-class outcome before giving full credit. → Added to Lessons Learned

Hypothesis

Testing: Can separating humid-night wet restraint from live-confirmed severe-day band-coupled assist reduce VPD-low overnight while preserving tomorrow’s VPD-high recovery despite forecast bias and guardrail materialization limits? Expected outcome: By sunrise, zero dp-risk hours and less VPD-low accumulation than today’s 2.47h pace; by tomorrow evening, VPD-high severity should improve relative to recent 6-15h hot-dry days without increasing dew-risk hours. Heat stress will likely persist because the forecast peak is physics-limited.

Conditions

humid VPD-low overnight with VPD forecast 0.20-0.47 kPa and dew margin currently 8.2F, followed by severe hot-dry Friday near 98F / RH 17-27% / solar around 900 W/m2; retrieval degraded by missing OPENAI_API_KEY and missing static/coverage context
