Peak Stress15:07TRANSITIONackedAcknowledged: Peak-stress transition checked live climate, equipment, active plan, and setpoints. Conditions are severe but tracking the SUNRISE plan: VENTILATE with both fans, vent, fog, and center mister active; wet/fog paths are allowed; dew margin is safe at about 14F. Tactical wet-assist knobs are already at or near the aggressive/guardrail-compatible floor (fog_escalation_kpa 0.10, mister_pulse_gap_s 22.5s, mister_engage_kpa 1.25 near vpd_high+0.05, 300 gal budget)...

House is warm and slightly VPD-high (82.8F, VPD 1.29 kPa vs high edge ~1.22-1.27) with safe dew margin 12.3F; controller is already in SEALED_MIST_FOG with vent/fans off and fog active, matching the plan’s measured-recovery posture. Existing setpoints remain band-coupled and aggressive enough for current dry recovery (mister_engage 1.07, all 1.26, gap 24, fog_escalation 0.15, 300 gal budget)... Resolved 19:31 MDT.

Validating previous cycle: iris-20260713-0544

Previous hypothesis: SUNRISE plan for Monday 2026-07-13. Daily scorecard is degraded by db_statement_timeout, and mandatory semantic retrieval is degraded because knowledge_search and lessons_search require OPENAI_API_KEY. I evaluated yesterday’s sunrise plan iris-20260712-0543 at 5/10, but the deterministic anchor was 2 because 640 VPD-high guardrail events and 573 held-by-guardrail events show the requested wet posture was repeatedly reshaped. I accept the anchor as the stronger materialization/compliance warning: safety and dew margin held, but VPD-high remained the limiting axis and water use rose to 413 gal. Current house is safe and inside corridor at about 70.3F, VPD 0.86 kPa, RH 66%, dew margin 11.8F, IDLE, with all relays off. Today’s forecast repeats extreme hot-dry stress: 100F, RH down to 8-11%, solar near 900 W/m2, and raw VPD near 6 kPa; corrected VPD remains severe after the morning ramp… Result: MIDNIGHT reset governed the early overnight/pre-dawn window before sunrise replacement. Window scorecard showed compliance about 70.8 with temp axis 50.6 and VPD axis 38.3; stress was dominated by VPD-high at about 2.60h plus heat stress 2.00h, with no cold stress and no dew-point risk. It correctly restored full wet-assist budget and kept dew/safety safe, but VPD remained the limiting axis and repeated guardrail/missed audit rows show materialization was still being reshaped. Outcome: safe but only partially effective at recovering the dry edge before the severe hot-dry daytime ramp. Score: 4/10

New finding: After midnight resets on consecutive extreme hot-dry July days, preserving full wet-assist budget is necessary but not sufficient; if VPD is still near/above band, keep guardrail-compatible moisture active through measured recovery and treat dispatcher guardrail/missed rows as evidence to request directly compatible values rather than relying on correction. → Added to Lessons Learned

Hypothesis

Testing: Test whether avoiding midnight/sunset resource taper until measured VPD recovery reduces guardrail reshaping and VPD-high alerts on the second severe hot-dry day. Expected outcome: Dew risk remains 0h; no water-budget clipping; VPD-high alerts improve versus 16.8h prior day if physics allows, with fewer guardrail-held events because requested values are band-coupled.

Validating previous cycle: iris-20260713-2031

Previous hypothesis: SUNSET plan for Monday 2026-07-13. Daily scorecard is degraded by db_statement_timeout and semantic retrieval is degraded because OPENAI_API_KEY is missing, so this plan is grounded in assembled context, live MCP climate/forecast/alerts, active lessons, plan evaluations, and controller action proof. I evaluated iris-20260713-0200 at 5/10 versus anchor 3 and iris-20260713-0544 at 5/10 versus anchor 2; the daytime self-score/anchor gap is because safety and dew margin held while the deterministic anchor correctly penalized 322 VPD-high guardrail events and 254 held-by-guardrail events. Today’s bottleneck was VPD-high, not dew or heating: current house is warm and dry-edge at about 79.7F, VPD 1.32 kPa vs high edge about 1.22, RH 62%, dew margin 14.1F, with no cold risk overnight… Result: SUNRISE plan governed the main 2026-07-14 severe hot-dry daylight window. Structured conditions matched directionally: outdoor peak 95.9F vs 97F forecast, actual solar peak 1077 W/m2 exceeded the 923 W/m2 forecast, and the humidity/VPD ramp was severe. The predicted heat and VPD-high stress windows both occurred. Window score was 57.8, with temp compliance 40.0%, VPD compliance 30.3%, heat stress 5.61h, VPD-high stress 7.09h, negligible VPD-low stress, no cold stress, and dew safety preserved. Rationale grading: full 300 gal wet budget avoided clipping but total water was high at 366 gal; band-coupled S1/all-zone assist and fog escalation were materialized only partly because guardrails repeatedly reshaped requested thresholds and gap values; shorter pulse gap and evening recovery helped safety but did not deliver VPD compliance; direct wet latest-hour intent appears missed/unsupported. Hypothesis was safe and correctly identified the stress class, but measurable compliance goals were only partially met and the plan overestimated how much wet/fog assist could offset physics-limited heat plus very high solar. Score: 4/10

New finding: On clear July days with solar above 1000 W/m2 and outdoor peak near 96F, aggressive band-coupled wet assist can preserve dew safety but may still leave both temp and VPD compliance poor; treat the day as physics-limited plus moisture-capacity-limited, keep requests directly guardrail-compatible, and do not expect fog/mist changes alone to recover VPD under sustained VENTILATE. → Added to Lessons Learned

Hypothesis

Testing: Test whether using guardrail-compatible wet assist all day and delaying evening taper until measured VPD recovery reduces VPD-high alerts versus the prior clock-based taper pattern. Expected outcome: Dew-risk hours remain 0; VPD-high alerts reduce versus yesterday’s 16.8h even if heat misses remain physics-limited; guardrail held events fall because requested intent matches the active moisture guardrail.

continue compliance-first wet assist for hotter 98F/RH 12-13% outlook

Parameter rationale

mister_water_budget_gal300.0 → 300.0; 97F/RH 12%/solar 923 W/m2 today after yesterday reached 16.8h VPD stress

avoid peak VPD recovery clipping; water should be spent only while readings are outside the corridor

mister_engage_kpa1.27 → 1.27; current VPD is in band but forecast crosses above band by 08:00-09:00 with dew margin 10.6F

keep S1 wet assist materialized near vpd_high+0.05 instead of relying on guardrail correction

mister_all_kpa1.44 → 1.44; prior vent_moisture_capacity_limit alerts and broad hot-dry ventilation pattern

keep all-zone recovery available near vpd_high+0.22 to +0.25 during persistent VPD-high

fog_escalation_kpa0.18 → 0.15; hot-dry VENTILATE overlaps the 07:00-17:00 firmware fog window and fog is the 7x wet path

reduce VPD-high band error during peak dry ventilation while dew margin remains above 8F

mister_pulse_gap_s30.0 → 24.0; solar >750 W/m2 from 11:00-16:00 and RH below 15% from 14:00-18:00

increase effective wet duty during peak stress without changing crop bands

direct_wet_stress_latest_hour21.0 → 22.0; forecast VPD remains above 2.5 kPa through 22:00 and yesterday evening VPD did not recover by clock taper

permit bounded evening recovery while dew margin is healthy, then taper only after measured recovery

Reflection

Validating previous cycle: iris-20260714-0545

Previous hypothesis: SUNRISE plan for Tuesday 2026-07-14. Yesterday’s daily scorecard endpoint is degraded by db_statement_timeout, and mandatory semantic retrieval is degraded because knowledge_search/lessons_search require OPENAI_API_KEY. I evaluated iris-20260713-0544 at 5/10, but plan_evaluate returned deterministic anchor 2 due 324 VPD-high guardrail events and 256 held-by-guardrail events; I accept the anchor as the stronger materialization warning. The forecast repeats an extreme clear hot-dry sequence: today 97F, RH 12-13%, solar 923 W/m2, raw VPD near 5.15 kPa, with corrected VPD still far above the Vanda/food corridor from late morning through evening. Current house is safe and in-band at about 69.3F, VPD 0.76 kPa, RH 69%, dew margin 10.6F, IDLE, all relays off… Result: SUNSET plan governed the late 2026-07-14 recovery / early 2026-07-15 pre-dawn window. It correctly diagnosed VPD-high as the remaining bottleneck after the severe hot-dry day and preserved dew safety: dp_margin_min stayed 8.8F for the day, with 0.0 dew-risk hours and no cold stress. However, the short governed window still scored only 58.9 with temp compliance 44.1% and VPD compliance 33.8%; stress in the window remained split between heat (~0.47h) and VPD-high (~0.55h). Daily 2026-07-14 score was 69.9, but VPD compliance was only 36.6% and VPD-high stress dominated at 13.96h versus 11.05h heat stress. Water use was high at 366 gal total and 171 gal mister water, well above the 167 gal 7-day average, while cost/energy fields were unavailable. Overall: safe and directionally correct, but only partially effective at dry-edge recovery and still guardrail/materialization-limited. Score: 4/10

Hypothesis

Testing: Test whether measured-recovery evening taper plus pre-dawn restoration preserves dew safety and reduces overnight water/churn without reopening VPD-high stress before the Wednesday dry ramp. Expected outcome: By 06:00, dew margin remains above 8F with 0 dp-risk hours, no cold stress, and VPD-high does not grow by more than 1 additional hour overnight; daytime handoff preserves wet-assist coverage if the 07:30 SUNRISE cycle is delayed.

45 min thermal lead, solar precool gain 1.4, VENTILATE wet/fog assist; accept structural cooling capacity limits near 96F

Parameter rationale

mister_engage_kpa1.27 → 1.27; live average VPD is served at 1.05 kPa but east is dry-edge at 1.34 kPa and today's VPD-high stress reached 11.14h

avoid suppressing S1 wet assist during the measured recovery window while dew margin remains safe

mister_all_kpa1.44 → 1.47; zone VPD spread exceeds 0.5 kPa and broad-house VPD alerts fired during peak heat

keep all-zone recovery available near vpd_high+0.25 through evening dry-edge recovery

mister_pulse_gap_s24.0 → 35.0; solar is zero overnight and humidity holds better sealed after recovery

reduce low-value overnight water and relay churn without clock-tapering before measured recovery

fog_escalation_kpa0.15 → 0.3; fog is firmware-blocked overnight and dew margin is safe; next morning handoff returns to 0.15 for the dry ramp

avoid unnecessary nighttime fog intent while preserving aggressive fog for Wednesday daylight VPD stress

mister_water_budget_gal300.0 → 300.0; current average VPD is served but east remains dry-edge and tomorrow repeats severe VPD-high risk

avoid clipping evening/morning recovery; only midnight posture modestly conserves after live recovery
