Reflection

Validating previous cycle: iris-20260823-0621

Previous hypothesis: SUNRISE plan for Sunday 2026-08-23. Saturday closed at legacy score 59.3 versus a 60.6 seven-day average. Temperature was the slightly weaker diagnostic axis at 48.3% versus 50.0% VPD compliance. Heat dominated at 10.89 h, followed by 8.70 h VPD-high, 1.41 h VPD-low, and 0 h cold. Dew safety held at 0 risk hours. Reliable attributable compliance and electric/gas/total-cost fields are unavailable, so no dollar or gas/electric attribution is claimed. Total water was 295 gal versus a 265 gal seven-day average; the stress and runtime pattern is cooling-and-misting dominated rather than heating. The elapsed MIDNIGHT plan iris-20260823-0025 is finally graded 2/10, matching the deterministic anchor. Its measured endpoint was safe—current VPD is inside the latest dispatcher corridor, dew margin is 8.7F, the moisture-gap alert resolved, and its 6 h window had 0.43 h VPD-high and 0… Result: Window 08-24 00:19 → 08-25 11:39 MDT: comp 51.9 (temp 50.9 / VPD 48.8), 11.18h stress (9.03h VPD-high, 2.27h VPD-low, 0 cold, 0h dp risk, min dp margin 7.6F). Band-coupled moisture posture (engage ~vpd_high+0.10-0.22, all +0.25-0.42, fog 0.15, gap 22s) worked structurally: guardrail audit shows 36 matched vs 4 guardrailed vs 21 already_at_value vs 6 missed — much better than clock-based unwinds, and dew safety held at 0h risk. But two hypothesis goals missed: (1) morning over-mist — aggressive wet assist from 08:00 while RH was still 64-71% and live VPD <1.1 kPa produced 2.27h VPD-low vs the <0.5h goal before the dry ramp arrived at 10:00-12:00; (2) the afternoon 12:00-16:00 hot-dry window (outdoor 84-87F, RH 23-31%, solar ~1139 W/m2 measured) drove 9.0h VPD-high; per the feasibility classifier most of it was physically unachievable (exhaust-only box, outdoor >= served-high) so it is not a tuning failure, but it did cap the score. 185 gal water (36 mister) vs 7d avg 349 — no cost signal (kwh/cost null). Net: posture mechanics correct, timing of the morning ramp wrong, residual afternoon stress structural. Score: 5/10

New finding: Morning over-mist window: on clear days following a cool humid dawn (RH 65-75%, VPD < 1.1 kPa until ~10:00), aggressive band-coupled wet assist active from 08:00 produces avoidable VPD-low stress (1.2-2.3h) before the dry ramp arrives at 10:00-12:00. Hold near-default moisture intensity (all-zone excess ~0.10-0.15, duty ~10%, fog escalation >= 0.30) through ~10:30 and only ramp to the compliance-first hot-dry posture (0.05/0.25-0.30, duty 20-25%, fog 0.15) once live VPD is confirmed above the dispatcher high edge or solar > 800 W/m2 with RH < 45%. The scored miss on these days is afternoon VPD-high, and the avoidable cost is morning VPD-low. → Added to Lessons Learned

Hypothesis

Testing: Retain guardrail-aligned band-coupled thresholds through pre-dawn and vary only bounded duty/resource posture; test whether this reduces held guardrail dependence while preserving dew safety. Expected outcome: By 02:30, reduce house VPD by at least 0.15 kPa from the 1.20 kPa start while keeping dew margin above 8F. Through the 08:00 handoff, keep VPD-low stress below 0.5 h and dew-risk at 0 h. Before 09:00, have +0.05/+0.20 kPa moisture engagement, 40% mist duty, 0.15 fog escalation, 60-minute thermal lead, 1.5F precooling, and 300-gal authority available for the forecast hot-dry ramp; accept residual 90F+ heat as physics-limited.
