Window scorecard: 65.7 scored compliance; legacy temp 46.5%, VPD 47.6%; 3.82h heat stress, 3.67h VPD-high, 0.01h VPD-low, 0h cold. Dew safety held. The recovery-bridge intent was directionally right, but VPD-high persisted for most of the window, so recovery effectiveness was weak despite avoiding humid overshoot and cold stress. Score: 4/10

Hypothesis

Testing: Keep assist edge-coupled through pre-dawn, then pre-stage fog at 07:00; test live-edge recovery without VPD-low overshoot. Expected outcome: Clear the live VPD-high error by 02:00; keep VPD-low, cold, and dew-risk at 0h through 08:30; after 07:00 allow no eligible VENTILATE moisture-gap over 15m and enter the 09:00 ramp with a 300-gal cap.

Validating previous cycle: iris-20260829-0017

Previous hypothesis: Prior plan self-score 5 versus anchor 7: the anchor credited safe/scored window outcomes, while I penalized 74/206 held guardrails, open push failures, and live VPD still above the high edge at rollover. Keep a band-coupled recovery bridge now rather than tapering by clock. Raw VPD forecasts overshoot reality by about 0.9 kPa; the bounded intent applies the maximum -0.4 kPa correction, so live readings govern. From 06:30 use 60-minute lead, 1.5-2F precooling, +0.05/+0.25 moisture thresholds, 30-35% duty, fog +0.15, and 300 gal capacity for the 09:00 hot-dry ramp. Result: Window score 60.4. Temperature and VPD legacy compliance were similarly weak at 46.0% and 46.3%. Heat stress 8.61h and VPD-high 8.08h dominated; cold was 0h and VPD-low 0.26h. The predicted high heat/VPD windows were directionally correct, but VPD-high exceeded the under-7h target. Outdoor peak was close (92.2F actual vs 95F), while solar was badly underforecast (1202 vs 595 W/m2). Dew safety held. Execution fidelity was poor: many guardrail holds plus missed/mismatched rows, including the requested 300-gal capacity, so nominal threshold changes did not reliably deliver the intended moisture posture. Resource cost fields were unavailable, preventing cost attribution. Score: 2/10

Hypothesis

Testing: Test whether 35% duty plus fog at +0.15 during the 08:30-17:00 window prevents long VPD-high moisture gaps without dew risk. Expected outcome: By 22:00: VPD-high stress under 7h, heat stress under 8h, zero dew-risk hours, no eligible VENTILATE moisture gap over 15m, and no daily mist-budget block.

Conditions

Mixed-cloud hot/dry day. Raw VPD peaks at 4.65 kPa near 15:00; apply the bounded -0.4 kPa correction but let live edge error govern. Yesterday’s peak temperature forecast was accurate.

Prior-day score was 62.7, but the cross-midnight window card for this plan returned zeros, so I graded from 15-minute climate/equipment history and alerts. VPD fell from 1.05 to 0.65 kPa around 19:45-21:15, producing more than the predicted <0.25h low-side exposure, then rebounded to 1.07-1.20 from about 22:00 through rollover. Alert 10544 confirmed VENTILATE VPD-high with no moisture assist for 15m at 22:15, and rollover VPD was 1.11 versus the 0.763 live high edge. Thus the selected-zone recovery/churn experiment did not avoid dry-low-dry oscillation or dry persistence. Dew safety held (current margin 16.7F; no disease-risk hours), cold stress remained zero, and no all-zone wetting was observed after 21:00. Two planned rows were missed and two were held by the sticky VPD-high guardrail, further weakening mechanism fidelity. The pre-dawn 04:30-06:30 prediction was not testable because the plan was replaced at midnight. Score: 4/10

New finding: When an evening plan crosses from VPD-high into a brief VPD-low dip and then back high, do not use a single clock-based conservative taper. Stage a measured-edge bridge: modest duty during the dip, then restore +0.05/+0.25 band-coupled assist if VPD re-crosses high with safe dew margin; verify the VENTILATE moisture path rather than assuming threshold changes delivered water. → Added to Lessons Learned

Hypothesis

Testing: Test whether selected-zone edge recovery to 21:00 plus high overnight churn penalty avoids both dry persistence and pre-dawn over-wetting. Expected outcome: By 06:30: evening VPD-high under 1.5h after plan start, overnight VPD-low under 0.25h, zero dew-risk and cold-stress hours, and no unnecessary all-zone wetting after 21:00.

Conditions

Mild cloudy night, outdoor low 61F. Live indoor VPD 1.07 with east 1.23 and safe 11.5F dew margin; 0-6h forecast VPD historically overshoots by 1.09 kPa. Prior day plan grade revised 5 to anchor 2 because 26/41 guardrail events were held and scored compliance was 57.5%.
