Validating previous cycle: iris-20260717-0547

Previous hypothesis: SUNRISE plan for Friday 2026-07-17. Yesterday was safe but not recovered: score 63.6, VPD compliance 35.9% vs temp compliance 49.1%, 14.30h VPD-high stress and 10.64h heat stress, no cold/VPD-low stress, dp_margin_min 8.4F. I scored the governing sunrise plan 5/10 for correct hot-dry diagnosis and dew safety, but plan_evaluate returned anchor 2 because 952 guardrail events and 861 held-by-guardrail events mean the plan was materially reshaped. This plan accepts the anchor warning by using bounded ClimateIntent rather than raw threshold thinking, and grades success as dew-safe severity reduction plus lower guardrail dependence, not full corridor recovery during physics-limited July heat. Retrieval was attempted as required but degraded because knowledge_search and lessons_search require OPENAI_API_KEY; static site context and plan coverage validation are also missing. Result: Scoped window score was 66.4 with temp compliance 50.0% and VPD compliance 38.7%. The reset plan correctly kept dew safety and avoided cold/VPD-low stress, but it did not materially restore the dry edge: scoped heat stress was 1.95h and VPD-high stress was 2.58h during the short overnight/early-morning window. The plan should be treated as a safe hot-dry handoff rather than a clean recovery experiment; later daylight stress remained dominated by physics-limited heat and VPD-high conditions. Score: 5/10

New finding: On July hot-dry reset windows, reopening band-coupled wet assist before sunrise preserves dew safety but should not be scored as recovery unless the following dawn or morning window shows VPD-high severity materially below the recent baseline and fewer guardrail-held/missed wet-assist materializations. → Added to Lessons Learned

Hypothesis

Testing: Guardrail-compatible Saturday hot-dry posture: preserve dew safety and keep daylight wet/fog assist band-coupled; judge success by lower VPD/heat severity and fewer guardrail conflicts, not full corridor recovery. Expected outcome: By sunset/midnight: 0h dew-risk, cold, and VPD-low stress; VPD-high and heat stress likely persist but should stay near or below recent hot-dry baseline severity; wet/fog assist should remain available during daylight VENTILATE while dew margin is safe.

Validating previous cycle: iris-20260717-2028

Previous hypothesis: SUNSET overnight plan for Friday 2026-07-17. Today scored 68.6, above the 7-day average 64.2, but still strongly bottlenecked by VPD: temp compliance 51.3% versus VPD compliance 36.8%, with 11.68h VPD-high stress and 8.12h heat stress, no cold or VPD-low stress, and dew safety held at dp_margin_min 9.0F / 0.0 dp_risk_hours. Resource cost terms remain unavailable; water was about 325 gal today versus 343 gal 7-day average, so the main resource constraint is water/wear rather than trusted cost accounting. I evaluated iris-20260717-0016 at 6/10 for safe pre-dawn operation, but plan_evaluate returned deterministic anchor 3 due 765 VPD-high guardrail events and 727 held-by-guardrail events; I accept the warning and treat recent plans as safe severity-reduction attempts, not clean parameter experiments. Current house is safe and near band at 81.1F, VPD 1.18 kPa, RH 67%, dew margin 11… Result: Validated at MIDNIGHT using the scoped window scorecard for the period governed by iris-20260718-0547. The diagnosis matched the day: actual outdoor temp peaked about 95.5F vs 95F forecast and solar peaked 1037 W/m2 vs 894 forecast, with the predicted high heat and VPD-high windows both materializing. The plan preserved the important safety rails: 0.0h cold stress, 0.0h VPD-low stress, daily dew margin minimum 8.8F, and 0.0 dew-risk hours. However, it did not achieve material corridor recovery: scoped score was only 54.4, temp compliance 39.3%, VPD compliance 30.4%, with 5.63h heat stress and 7.17h VPD-high stress in the governed window; full-day totals stayed high at 11.09h heat and 14.13h VPD-high stress. Water rose to 359 gal total and 162 gal misting-only versus a 345 gal 7-day water average, so the extra wet assist bought safety/severity mitigation but not a clean compliance win. The rationale items for earlier mist/fog were directionally correct but guardrail-heavy materialization and physical cooling limits mean they should be treated as severity-reduction attempts, not successful recovery experiments. The structured stress-window severity matched reality, but the expected effects of band-coupled S1/all-zone mist and daylight fog did not reduce VPD-high below the recent July baseline. Score: 4/10

New finding: On July extreme hot-dry days with solar near or above 1000 W/m2 and outdoor highs around 95F+, band-coupled wet assist and fog escalation can preserve dew safety and avoid VPD-low overshoot, but should be scored as severity mitigation rather than recovery unless scoped VPD-high hours fall below the recent baseline; repeated guardrail materialization means future plans should request guardrail-compatible wet-assist values directly instead of relying on dispatcher correction. → Added to Lessons Learned

Hypothesis

Testing: Guardrail-compatible hot-dry severity-reduction test: request band-coupled wet/fog assist via bounded ClimateIntent and judge success by lower VPD-high severity, dew safety, and fewer guardrail-held materializations, not full corridor recovery during physics-limited peak heat. Expected outcome: Dew risk remains 0h with dp_margin_min above 8F; VPD-high stress should stay below yesterday’s 14.53h if guardrail-compatible materialization succeeds; heat stress may remain structural near 8-11h under 95F clear conditions; water may run near or slightly above the 343 gal 7-day average but should not be clipped by the daily wet budget.

Conditions

clear July hot-dry day; forecast VPD is positively biased but corrected priors and recent history still indicate severe VPD-high plus physics-limited heat stress from midmorning through evening

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 at Sunday SUNRISE using the governed overnight/evening window and daily scorecard. The plan preserved safety: no cold stress, no VPD-low stress, and daily dew safety held at dp_margin_min_f 8.8F with 0.0 dp-risk hours. However, it did not achieve dry-edge recovery: the scoped window scored 57.2 with temp compliance 41.1%, VPD compliance 28.8%, about 0.51h heat stress and 0.61h VPD-high stress during only 3.8h of governance, and the full Saturday stayed VPD-high dominated at 14.13h VPD-high and 11.09h heat stress. Water was 359 gal total and 162 gal misting-only versus a 345 gal 7-day water average, so water increased without a clean VPD compliance win. The forecast/stress framing was correct, but the taper was still mainly a safe handoff rather than recovery; direct_wet_stress_latest_hour also missed materialization at 21 instead of 22, so the evening recovery surface was less available than intended. Score: 4/10

New finding: On July extreme hot-dry evenings before another severe hot-dry day, a clock-based wet-assist taper preserves dew safety but should not be treated as VPD recovery unless the governed window shows VPD-high materially below baseline; verify direct_wet_stress_latest_hour materializes before relying on bounded evening dry-edge recovery. → Added to Lessons Learned

Hypothesis

Testing: Overnight dry-edge taper with dew-safe conservation, followed by pre-dawn reopening before Sunday’s extreme hot-dry ramp. Expected outcome: Maintain 0h dew-risk and 0h VPD-low overnight, avoid low-value water churn after 22:30, and enter Sunday morning with wet/fog assist reopened early enough to reduce VPD-high severity versus the last 7-day baseline even if peak heat remains physics-limited.

Conditions

warm dry evening after VPD-high and heat dominated Saturday; dew margin is safe, east is the dry outlier, and Sunday is forecast clear/extreme hot-dry with raw VPD positively biased but still severe after correction
