Forecast deviation08:50FORECAST_DEVIATIONackedAcknowledged: Cloud-cover forecast missed clear sky, but live solar is only 206 W/m2, indoor 74.5F/0.98 kPa remains inside the 66.99-76.99F and 0.462-1.012 kPa corridor, dew margin is 11.7F, controller is IDLE, and all climate equipment is off. No measured hot/dry edge miss yet; retain the active 09:30 ramp rather than tune on cloud cover alone. Resolved 08:56 MDT.
Solar peak planning checkpoint13:03SOLAR_MAXackedAcknowledged: SOLAR_MAX no change: live solar 864 W/m2 exceeded the plan's 612 W/m2 peak despite the +47 W/m2 forecast overshoot bias, but indoor VPD is stable/recovering at 1.13 kPa (12:00 1.22, 13:00 1.12), east/west are 0.94/0.95, dew margin is 10.3F, and the 13:30 hot-dry waypoint already tightens wet assist for the afternoon. Resolved 13:03 MDT.
Peak Stress15:02TRANSITIONackedAcknowledged: Peak stress is tracking the active plan: 84.6F/1.24 kPa, 11.0F dew margin, solar 332 W/m2, controller IDLE, and all relays off. Existing wet assist is already aggressive (engage 0.956 kPa, 22s gap, fog +0.15); no stronger override is justified. Resolved 15:04 MDT.
Decline18:35TRANSITIONackedAcknowledged: Decline no-op: live VPD remains elevated at 1.25 kPa (east 1.42) with a safe 13.3F dew margin, so sticky moisture guardrails correctly retain band-coupled assist. Equipment is idle/off, and the active plan already schedules a conservative 21:30 taper (gap 60s, fog escalation 0.5) after measured recovery. Resolved 18:36 MDT.

Previous hypothesis: {“conditions”:{“outdoor_temp_peak_f”:89,“outdoor_rh_min_pct”:21,“solar_peak_w_m2”:728,“cloud_cover_avg_pct”:90,“notes”:“Overcast dawn becomes hot and dry near midday.

Window score/compliance was 43.4%, with temp 46.2% and VPD 40.6%; VPD remained the weaker axis and dry-edge exposure persisted. The live-edge recovery bridge was directionally correct and dew/cold safety held, but corridor time stayed poor and the forecast taper/daytime reopen was superseded before it could be tested. Score reflects the governed window only, not later forecast windows. Score: 3/10

New finding: Short recovery bridges must be graded on governed-window corridor compliance; zero dew/cold risk is only a safety guard, not evidence of successful VPD recovery. → Added to Lessons Learned

Hypothesis

Testing: Measured-edge recovery bridge, humidity-safe taper, then guardrail-compatible reopening before the hot/dry ramp. Expected outcome: By 03:15 measured VPD reaches the active high edge; through 09:00 VPD-low stays under 0.5h with 0h dew/cold risk. While governing after 09:00, no eligible VENTILATE VPD-high moisture gap exceeds 15m; mist budget stays at or below 300 gal.

Reported window compliance was 76.6% (temp 68.5%, VPD 79.2%) with 0.74h heat, 0.11h VPD-high, 0h cold and 0h VPD-low. Dew safety held. Only the pre-dawn posture was testable; later daytime hot-dry waypoints were superseded and receive no credit. The governed interval was materially better than the recent 61.4% baseline, though temperature remained the weaker axis and full-plan causal attribution is limited. Score: 7/10

Hypothesis

Testing: Band-coupled daytime wet assist with a measured-edge overnight taper across alternating hot-dry and humid windows. Expected outcome: On each governed day: zero dew-risk; VPD-high under 8h Monday/Tuesday and under 10h Wednesday; VPD-low under 1.5h; no eligible VENTILATE moisture gap over 15m; governing-window compliance above 55%; mist budget at or below 300 gal.

Previous hypothesis: Prior plan window compliance was 45.9%; self-score 4 versus anchor 1. I credited the broad VPD-high <9h goal and zero dew risk, while the anchor appropriately penalized only 8 dispatched and 63 held of 345 guardrail events plus poor corridor time. Live VPD 1.20 is above the 0.763 high edge with an 18.7F dew margin and an open VENTILATE moisture-gap alert, so start with +0.05/+0.25 recovery. Request a 03:15 taper for the humid trough; the sticky guardrail should retain aggression if measured VPD has not recovered. At 09:00 reopen full band-coupled assist and 2F precooling before corrected VPD reaches 2.1-2.6 kPa and temperature 83-86F. Semantic retrieval failed because OPENAI_API_KEY is missing; this safe plan uses fresh MCP telemetry and the validated MIDNIGHT/hot-dry lessons. Result: Governed 06:33-19:43 MDT only. Window score: 76.9% compliance (temp 73.1%, VPD 77.6%), 1.94 h heat stress, 0.29 h VPD-high, 0 h cold/VPD-low/dew risk; water 113 gal, mister 33 gal, minimum dew margin 7.1F. VPD-high <8 h, VPD-low <1.5 h, water ⇐300 gal, and dew safety met, but corridor time and temperature were only partial. Forecast materially overpredicted dryness/heat: outdoor peak 84.8F vs 89F, RH proxy 49% vs 17%, solar 1024 vs 612 W/m2. Later windows were superseded and not credited. Score 6: safety and stress goals met, but not strong corridor performance. Score: 6/10

New finding: On forecast hot/dry days, when RH and temperature are materially overpredicted but solar is higher, keep moisture assist band-coupled and let measured VPD/edge error govern; zero dew/VPD-low risk is not success without corridor compliance. → Added to Lessons Learned

Hypothesis

Testing: Delay maximum wet duty until the measured dry ramp, then test 30-35% duty plus 0.15 fog escalation against corridor time and low-side overshoot. Expected outcome: Governing-window compliance above 55%; VPD-high under 8h, VPD-low under 1.5h, dew-risk 0h, no eligible VENTILATE moisture gap over 15m, and mist water at or below 300 gal.

Use 45-60 min thermal lead and up to 2F precooling; accept physically limited residual heat.

Parameter rationale

fog_escalation_kpa0.25 → 0.15; 89F, 17% RH and corrected peak VPD near 2.9 kPa; dew margin is 11.3F.

Prevent eligible VENTILATE moisture gaps over 15 minutes during peak stress.

mister_pulse_gap_s33.0 → 22.0; Corrected VPD rises above the crop corridor from late morning through evening.

Hold VPD-high under 8 hours while keeping VPD-low under 1.5 hours.

mister_water_budget_gal180.0 → 300.0; Yesterday used only 12 gal of mist water while VPD-high reached 9.01 hours.

Avoid budget-limited recovery while keeping daily mist water at or below 300 gal.

Safety goals held, but VPD corridor time was weak and the 22:54 house-band-drift alert showed the house too wet (0.58 kPa vs 0.76-1.19). The short edge-recovery/taper avoided measurable stress but did not deliver strong corridor control. Resource cost was unavailable, so efficiency was not gradeable. Forecast retrieval was degraded by missing semantic-embedding credentials. Score: 5/10

Hypothesis

Testing: Taper from short edge recovery to 5% overnight duty, then reopen modest pre-dawn authority only on measured error. Expected outcome: Overnight corridor compliance above 70%; VPD-low under 0.75h, VPD-high under 0.75h, cold stress 0h, dew-risk 0h, with no humidify/dehumidify whipsaw.

Conditions

Outdoor peak

73.0°F

RH minimum

33.0%

Solar peak

41.0 W/m²

Cloud average

90.0%

Mild 59-73F humidifying night; live VPD 1.01 kPa and dew margin 10.7F. Forecast VPD has a +1.02 kPa overshoot bias; apply the bounded -0.4 kPa discount and let measured edges govern. Prior plan self-score 7 vs anchor 5 because only 2/152 guardrail events dispatched and 60 were held; I overcredited corridor and safety evidence. Retrieval failed because OPENAI_API_KEY is missing; use fresh MCP telemetry and validated static lessons.

Expected stress windows

vpd_highlow · 2026-08-31T19:35:00-06:00 to 2026-08-31T22:30:00-06:00

Allow short selected-zone edge recovery at +0.05 with 12% duty while measured VPD stays high; hold fog back.

vpd_lowmedium · 2026-09-01T00:30:00-06:00 to 2026-09-01T07:30:00-06:00

Raise wet thresholds, cap duty at 5%, require 11F dew margin, and use stable advantageous air exchange.

Parameter rationale

mister_pulse_gap_s37.5 → 60.0; Raw VPD falls from 0.81 at midnight to 0.30 at 07:00 while RH rises from 62% to 82%.

Keep VPD-low exposure below 0.75h and dew-risk at 0h overnight.

mister_engage_kpa0.956 → 1.32; Live VPD is only 0.07 above the served high edge and forecast humidity increases after midnight.

Preserve measured-edge recovery without wetting inside the overnight corridor.

vent_prefer_temp_delta_f4.0 → 7.0; Temperature falls toward 59F while VPD crosses from dry-edge to humid-edge conditions.

Avoid rapid humidify/dehumidify whipsaw and keep cold stress at 0h.
