Result: ESP32 firmware crashed Saturday afternoon (1:30-5:30 PM). State machine failure: fog+fans at 48F, no misters at VPD 3.61. Plan hypothesis (earlier aggressive deploy) never tested. Firmware was fixed and ESP32 rebooted Sunday morning. 6.93h VPD stress, 0h heat stress.
Reflection
Validating previous cycle: iris-20260403-1100
Previous hypothesis: New lesson: cold-dry days dont produce VPD stress because temp drives VPD more than RH. Fri proved this (0h stress at 22% RH but 49F). Sat will test the boundary: outdoor crosses 60F by noon with 12% RH — that is when VPD stress starts. Deploy aggressive misting only once outdoor >60F. Result: ESP32 firmware crashed Saturday afternoon (1:30-5:30 PM). State machine failure: fog+fans at 48F, no misters at VPD 3.61. Plan hypothesis (earlier aggressive deploy) never tested. Firmware was fixed and ESP32 rebooted Sunday morning. 6.93h VPD stress, 0h heat stress. Score: 1/10
New finding: ESP32 firmware crash invalidated plan entirely. State machine bugs can override all planning. Firmware stability is prerequisite to plan effectiveness. → Added to Lessons Learned
Hypothesis
Conditions: Noon Sat: south 87F/VPD 2.32, avg 78.8F/47% RH. Outdoor 54F/16% RH rising to 64F peak. Sunday extreme: 35F dawn, 67F/12% RH peak (outdoor VPD 1.94 — highest of window). Monday overcast 100% clouds with rain, 65F/23% RH, moderate. Testing: Sunday 11AM aggressive deployment (engage=1.3, gap=30s) vs previous noon deployment. Measure: Sunday VPD stress hours and compare to Sat (similar dry but delayed deploy). If 11AM catches the ramp, stress should be 1-2h less than equivalent noon deployment. Expected outcome: Sat VPD stress <4h (noon plan deployed late). Sun VPD stress <3h (early deploy). Mon VPD stress <1h (overcast). Total 3-day water <400 gal.
