Safety/no-dew held, but cold/VPD exposure and 26 missed versus 24 already-at-value transition rows weaken causal attribution. Resource cost, physical crop-band evidence, and DLI were unavailable; no durable new lesson beyond existing low-wet/dwell guidance. Score: 5/10

Hypothesis

Testing: Compare low-wet pre-dawn stability with a gradual cloudy-day moisture ramp; judge by stress hours and execution/readback evidence, not target distance. Expected outcome: Keep dew-risk and VPD-low at 0h overnight, keep pre-dawn wet duty off, begin assist before forecast VPD reaches the high edge, and avoid ordinary relay churn. Physical, cost, and DLI attribution remain unavailable.

Validating previous cycle: iris-20260929-0016

Previous hypothesis: Evaluated iris-20260928-0202 at 4/10 versus deterministic anchor 1. The gap reflects safety/no-dew success despite unproven guardrail attribution; cold stress 2.60h and VPD-high stress 1.98h show the objective was incomplete. Fresh telemetry is 68.2F/0.75 kPa VPD with 10.8F dew margin and IDLE. Forecast is cool/overcast, with VPD rising gradually to 1.20 kPa. Maintain low-wet overnight and stable dwell, then enable bounded band-coupled assist at the cloudy daytime edge. Retrieval degraded: both semantic searches require OPENAI_API_KEY; use live telemetry and validated lessons only. Result: Scoped sunset/overnight window had 100% binary VPD compliance, zero nominal stress, 1.52h cold exposure, and no dew-risk; low-wet posture protected moisture safety but thermal exposure remained and physical crop-band, cost, and DLI evidence were unavailable. Score: 6/10

Hypothesis

Conditions

Outdoor peak

RH minimum

Solar peak

0.0 W/m²

Cloud average

96.0%

Cool cloudy overnight: outdoor VPD falls 1.37 to 0.25 kPa and indoor dew margin is 9.1F. Temperature was today’s bottleneck (34.4% binary compliance; 9.87h cold stress), while today’s self-score 5 versus deterministic anchor 1 reflects safety/no-dew success but 26 missed transitions and 76 guardrail holds; causal benefit remains unproven.

Expected stress windows

coldhigh · 2026-09-29T19:00:00-06:00 to 2026-09-30T06:00:00-06:00

Stable heat/vent posture, wider thermal hysteresis, and high relay-churn penalty; avoid wet cycling.

vpd_lowmedium · 2026-09-30T02:00:00-06:00 to 2026-09-30T06:00:00-06:00

60s mister gap, high fog threshold, and 8F dew floor through the humid trough.

Parameter rationale

temp_hysteresis1.87 → 2.0; 56-65F outdoor and 9.87h cold stress today

Reduce heater-to-vent oscillation and cold excursions without changing crop bands.

mister_pulse_gap_s41.25 → 60.0; Forecast VPD declines below 0.44 kPa after 03:00

Reduce overnight wet cycling and protect the 8F dew-margin floor.

fog_escalation_kpa0.2 → 0.5; Fog is unavailable overnight and outdoor RH rises to 84% by 06:00

Keep heavy wet assist deferred during the cold humid trough.
