Validating previous cycle: iris-20260727-0555

Previous hypothesis: SUNRISE plan for Monday 2026-07-27. Yesterday closed strong at score 81.4 vs 65.5 7-day average, with dew safety intact (dp_min 8.1F, dp-risk 0h) and no cold or VPD-low stress. VPD remained the bottleneck: temp compliance 54.0%, VPD compliance 48.9%, with 22.66h total stress dominated by VPD-high 12.0h and heat 10.66h. I scored iris-20260726-0555 at 7/10 because it improved the daily score and protected dew safety, but the deterministic anchor was 2 due to 208 VPD-high guardrail events and 165 held events. I accept the gap: the outcome was good partly because the dispatcher repaired the requested moisture surface. Today’s plan therefore asks closer to the band-coupled guardrail surface through ClimateIntent: low moisture excess, earlier all-zone assist, short daytime wet duty, fog available during the 07:00-17:00 window, and a rapid taper when the 22:00 humid/storm recovery arrives… Result: Evaluated the completed early Tuesday plan from the window scorecard. The short governed window ended at planner score/compliance 60.4, below the 66.9 seven-day average, with temp compliance 54.1% and VPD compliance 53.9%. Stress remained dual-axis but heat was the larger component in the window (about 1.84h heat, 1.08h VPD-high, 0.73h VPD-low, no cold). Dew safety held with daily dp_min 6.3F and 0h dew-risk, so the humid-night safety hypothesis was only partially validated. Materialization remained dirty: recent clamps/guardrails show many VPD-high moisture guardrail holds, so the next plan should avoid both overly conservative wet thresholds while VPD is still high and overly aggressive overnight wetting when forecast RH rises. Score: 5/10

New finding: After a hot/VPD-high day, the sunset-to-midnight taper should be two-phase: keep a short guardrail-clean wet-assist recovery while live VPD remains at/above the high edge and dew margin is safe, then taper sharply only after observed VPD recovery or the humid forecast arrives. → Added to Lessons Learned

Hypothesis

Testing: Guardrail-clean midnight restart: keep humid-night wet assist conservative only after live VPD has recovered, then reopen band-coupled wet/fog assist for the hot-dry morning ramp and repeat storm-night tapers. Expected outcome: By the next SUNRISE: 0h dew-risk, 0h cold stress, VPD-low under 1h, and fewer VPD-high moisture guardrail holds than iris-20260727-2020; during Tue daytime, accept structural heat but keep VPD assist available near the band edge when dew margin is safe.

storm-humid taper with high dew margin and low wet duty

Parameter rationale

mister_engage_kpa0.82 → 1.27; active vpd_high near 1.22 kPa; daytime corrected VPD remains above band but overnight live VPD has recovered below high edge

request S1 wet assist near the high edge during dry stress without triggering repeated conservative-threshold guardrail holds

mister_all_kpa1.03 → 1.44; broad dry stress is likely from late morning through afternoon, but humid nights need taper

allow all-zone assist during broad daytime dry stress while reducing overnight VPD-low risk

mister_pulse_gap_s30.0 → 22.0; hot/dry lessons call for 15-25s effective gaps during VENTILATE dry stress; long overnight gaps were held by guardrail while VPD-high was active

improve VPD recovery during hot/dry windows and reduce held guardrail repairs

fog_escalation_kpa0.2 → 0.18; midday VPD-high overlaps the 07:00-17:00 fog window with dew margin currently safe

make 7x fog assist available earlier during hot-dry VENTILATE while keeping fog held back in humid overnight windows

mister_water_budget_gal160.0 → 280.0; water is not binding and VPD-high remains the repeated daily bottleneck; resource cost fields are unavailable

avoid budget-limited daytime VPD recovery while still using low effective duty during humid night segments

Validating previous cycle: iris-20260727-2020

Previous hypothesis: SUNSET overnight plan for Monday 2026-07-27. Today scored 77.4 versus a 67.2 seven-day baseline, so the guardrail-clean wet-assist strategy was directionally helpful, but the axis split stayed weak and even: temp compliance 49.5%, VPD compliance 49.4%. Stress was dominated by heat 8.43h and VPD-high 8.50h, with 0h cold, 0h VPD-low, dp_min 7.9F, and 0h dew-risk. Cost fields are unavailable, so I am using water/wear runtime context only; total water context remains below the 298 gal 7-day average, and resource terms are not score-eligible. I evaluated iris-20260727-0201 at 6/10 versus anchor 5 and iris-20260727-0555 at 6/10 versus anchor 3. I accept the anchor warning on the SUNRISE plan: dew-safe outcome and above-baseline score justify a moderate human score, but 200 VPD-high guardrail events and 166 held events mean the plan still depended too much on dispatcher repair… Result: Validated the completed SUNRISE governing window for 2026-07-28 using the window scorecard, not the daily summary. The plan governed about 0.599 of the day and scored 49.7, below the surrounding 59.4 day/window reference, with temp compliance 43.1% and VPD compliance 44.0%. Stress totaled 5.13h in the window: heat 3.19h was the largest miss, VPD-high 1.62h was secondary, VPD-low 0.00h, cold 0.00h. The forecast/hypothesis overcalled dry heat in one way and undercalled solar in another: predicted outdoor peak 95F vs actual 91.6F, indoor RH proxy 61% vs predicted 24% outdoor RH, but solar peak was 1152 W/m2 vs predicted 847. Stress-window grades: dawn low VPD-low risk was met with no VPD-low; daytime heat/VPD-high risk was real but heat dominated more than VPD-high and compliance remained poor; evening humid taper avoided VPD-low during this evaluated window. Rationale grades: lower mister_engage_kpa and mister_all_kpa plus short pulse gap/fog access likely kept VPD-high below the worst recent days, but did not deliver clean high compliance; higher water budget was not binding because total water was only 80 gal; direct_wet cutoff did not produce an observable evaluated-window failure. Overall: safe dew and no overshoot, but weak corridor compliance and still substantial hot/solar capacity stress, so 5/10. Score: 5/10

New finding: When actual RH stays much higher than a hot/dry forecast but solar is extreme (>1100 W/m2), heat can dominate over VPD-high even with guardrail-clean wet assist; keep band-coupled moisture available, but do not expect wet/fog posture alone to recover compliance under extreme solar without shade/cooling capacity. → Added to Lessons Learned

Hypothesis

Testing: Guardrail-clean hot-dry ramp: request ClimateIntent close to the VPD-high guardrail surface during live dry stress, then taper only after forecast/observed evening recovery, to reduce held guardrail repairs while preserving dew safety. Expected outcome: Today should keep dew-risk at 0h, avoid VPD-low overshoot, improve or hold score above the 67.2 seven-day baseline, and reduce VPD-high guardrail holds versus Monday’s 166 held events even though 90F+ heat remains partly structural.

Thursday hotter/drier ramp gets early band-coupled wet assist and high daily mist budget

Parameter rationale

mister_engage_kpa1.34 → 1.27; active vpd_high near 1.22 kPa and corrected VPD above band from late morning through evening; yesterday had 200 VPD-high guardrail events

make S1 wet assist available close to the high edge with fewer conservative-threshold guardrail holds

mister_all_kpa1.54 → 1.44; broad hot dry stress expected under solar 847 W/m2 and RH down to 24%

bring all-zone rotation in for broad dry stress without suppressing wet assist

mister_pulse_gap_s60.0 → 20.0; hot/dry lessons call for 15-25s effective gaps and recent guardrails held long gaps to 30s during live VPD-high stress

increase useful wet duty during confirmed VPD-high windows while reducing held guardrail repairs

fog_escalation_kpa0.45 → 0.16; VPD-high overlaps the 07:00-17:00 fog window and fog is 7x misters; dew margin starts at 8F and firmware gates RH/temp/time

make fog assist available earlier during hot-dry VENTILATE without extending heavy fog into humid night

mister_water_budget_gal150.0 → 280.0; VPD-high was yesterday’s dominant stress and water was 241 gal vs 298 gal seven-day average; cost fields remain unavailable

avoid budget-limited VPD recovery while dew and occupancy rails are safe

direct_wet_stress_latest_hour21.0 → 21.0; forecast remains dry through about 21:00 then turns humid by 23:00

preserve evening dry recovery but stop before humid overnight VPD-low risk

Validating previous cycle: iris-20260728-0556

Previous hypothesis: SUNRISE plan for Tuesday 2026-07-28. Yesterday scored 72.1 versus a 67.2 seven-day baseline, with dew safety intact (dp_min 7.9F, dp-risk 0h), no cold stress, and no VPD-low stress. The bottleneck was hot/dry dual-axis stress, slightly worse on VPD: temp compliance 47.3%, VPD compliance 46.9%, heat stress 10.93h, VPD-high stress 11.08h. I scored iris-20260727-0555 at 6/10 because it improved the daily score and protected dew safety, but plan_evaluate returned anchor 2 due to 200 VPD-high guardrail events and 166 held events. I accept the gap: the outcome was operationally safe, but materialization was dirty. Today’s plan asks closer to the dispatcher VPD-high guardrail surface during dry stress instead of relying on repair. Mandatory semantic retrieval was attempted, but knowledge_search and lessons_search are degraded because OPENAI_API_KEY is missing for query embeddings… Result: SUNSET window scorecard covered 16.5% of the day and scored 56.1, below the 66.9 7-day baseline. Temp compliance was 44.9% and VPD compliance 40.4%, so VPD was the tighter axis in this governed window. Stress was modest in absolute hours because the window was short, but dominated by VPD-high (0.41h) over heat (0.05h), with no cold or VPD-low. The two-phase sunset taper was directionally right for avoiding VPD-low/dew risk, but the evening recovery surface did not fully clear VPD-high before the humid taper. Daily dew safety held (dp_min 6.3F, 0h dp risk). Utility cost fields were unavailable; total day water context was 80 gal versus 245 gal 7-day average, so water was not binding. Overall safe dew/no cold, but weak corridor compliance and partial VPD-high recovery only. Score: 5/10

New finding: On humid-storm sunset transitions after a hot day, tapering wet assist protects dew safety, but if the governed window still shows VPD-high dominance, keep the first recovery segment guardrail-clean and long enough to verify observed VPD recovery before the sharp humid-night taper. → Added to Lessons Learned

Hypothesis

Testing: Two-phase sunset taper: short dew-safe VPD-edge recovery, then humid-night wet suppression, with guardrail-clean morning handoff if SUNRISE is delayed. Expected outcome: Overnight dp_risk_hours remains 0, VPD-low stress stays under 4h despite raw VPD 0.09-0.51 forecast, no cold stress, and Wednesday morning starts dew-safe with wet assist ready before the hot/dry ramp.

heathigh · 2026-07-29T12:00:00-06:00 to 2026-07-29T16:00:00-06:00

morning handoff keeps thermal lead and evaporative assist available while accepting physics-limited cooling above 90F

Parameter rationale

mister_engage_kpa1.0 → 1.27; live VPD 1.21 kPa is at the current 1.22 kPa high edge with dew margin 13.6F, but forecast turns humid after 22:00

address the current vent/VPD moisture-gap alert briefly without carrying aggressive wetting into the humid night

mister_all_kpa1.2 → 1.47; zone VPD spread was elevated earlier but the overnight forecast is broad humid recovery; Wednesday midday returns to dry stress

avoid broad overnight all-zone wetting while preserving a guardrail-clean dry-ramp handoff

mister_pulse_gap_s30.0 → 55.0; overnight RH forecast rises to 80-96% and raw VPD falls to 0.51-0.09 kPa

reduce VPD-low overshoot, water use, and mister cycling overnight

fog_escalation_kpa0.15 → 0.5; fog window is closed overnight and humid air raises VPD-low/dew risk despite safe current dew margin

hold the 7x wet assist back through humid hours, then allow a lower morning threshold only if dry ramp confirms

mister_water_budget_gal250.0 → 140.0; today's water context is below the 7-day average and water is not binding, but overnight stress shifts from dry to humid

bound overnight water/wear without limiting tomorrow’s required VPD-high recovery after the morning handoff

direct_wet_stress_latest_hour21.0 → 21.0; forecast VPD collapses after 22:00 and wet recovery is only useful during the current 20:19-21:00 dew-safe edge window

preserve a short evening recovery cutoff and prevent wet assist from extending into the humid-night risk window
