Previous hypothesis: Tuesday Apr 21 is the second consecutive extreme dry-hot day in the away-plan window. Clear skies until 5 PM, outdoor 83°F peak (bias-corrected ~86°F), 7-9% RH all day. Outdoor VPD peaks 3.58 kPa at 4 PM. This is a physics-limited day — indoor will exceed 90°F regardless of control strategy (lesson #5). Strategy: maximum misting aggression from 09:30, fog escalation at 0.25 kPa during solar peak (12-3 PM), shortened sealed windows (420s at peak) per lesson #9 (thermal trap risk). Accept 5-8h heat stress as structural. Wednesday is worse: 85°F/4% RH, 14-23 mph wind. Cloudier morning delays VPD ramp by ~1h but clearing PM with extreme dryness and wind. Wider misting gap (20s vs 15s) during morning due to wind-accelerated evaporation, tightening to 15s at PM peak. Wind improves fan cooling but reduces sealed-vent misting effectiveness. Thursday: cold front. 68°F overcast, 10% RH… Result: [backfill] compliance unavailable over plan window 2026-04-26 21:08 → 2026-04-26 21:11 Score: 4/10

Hypothesis

Testing: Recovery from stale planner defaults; verify conservative humid/cool posture. Expected outcome: No new VPD-low runaway; active plan present; dispatcher no longer flying stale Apr21 plan.

Result: 2026-04-26 finished at planner_score 31.1 with 28.9% both-axis compliance. VPD compliance (44.6%) was the bottleneck vs temp compliance 56.9%, but the actual stress was entirely VPD-low (11.27h) with no heat, cold, or VPD-high stress in the frozen daily summary. Cost was high at USD 9.00, above the 7d avg USD 6.30, driven mostly by gas (USD 5.04 / 6.076 therms) plus elevated electric (24.78 kWh) and water 249 gal. Dew point safety degraded: dp_margin_min 3.1F and 4.5 dp-risk hours. The recovery plan restored coverage but remained too humid/cold-saturated for the actual overcast high-RH day. Score: 3/10

New finding: On cool, overcast, high-RH recovery days, conservative mist/fog inhibition alone is not enough: avoid holding VPD below band for hours. Use wider/no-mist thresholds, shorter sealed windows, and deliberate ventilation/dehumid posture while preserving dew point margin >5F. → Added to Lessons Learned

Hypothesis

Testing: Restore complete dispatcher waypoint coverage after planner recovery. Expected outcome: No planner_stale critical alert; active waypoints through Monday afternoon; lower mist/fog duty during high-RH periods.
