Forecast deviation	08:43	FORECAST_DEVIATION	acked	Acknowledged: Observed cloud cover 100% with 0 solar sustained 11:45–14:30Z versus 5% forecast; live indoor 73.6F, VPD 0.87, RH 70%, dew margin 10.6F, IDLE. All relays are off and no controller response is demanded. Classify as forecast/weather miss, not equipment fault; no tunable change justified. Resolved 08:44 MDT.
Forecast deviation	11:14	FORECAST_DEVIATION	acked	Acknowledged: Live solar miss is a weather/nowcast shift: solar is 0 W/m² with fresh telemetry, while indoor climate is 82.9°F, VPD 1.20 kPa, dew margin 11.3°F, and controller is correctly IDLE with all climate relays off. The 675 W/m² miss exceeds the usual +47 W/m² solar bias, so it is not merely calibration catch-up. No marginal tunable change is justified; monitor the warm trajectory. Semantic retrieval was attempted but unavailable because OPENAI_API_KEY is missing. Resolved 11:14 MDT.
Solar peak planning checkpoint	13:00	SOLAR_MAX	action_completed	Delivery recorded without a public plan write. Resolved 13:01 MDT.
Forecast deviation	13:14	FORECAST_DEVIATION	acked	Acknowledged: Observed solar was 0 W/m² versus 850 forecast, but live indoor climate is still hot/dry (85.1°F, VPD 1.71) with healthy 15.9°F dew margin and saturated VENTILATE response (vent + both fans + fog on). No marginal benefit from cosmetic tuning; retain sticky wet assist and monitor. Semantic retrieval failed because OPENAI_API_KEY is unavailable. Resolved 13:14 MDT.
Forecast deviation	13:44	FORECAST_DEVIATION	acked	Acknowledged: Observed VPD 0.94 in the deviation payload is below forecast 2.99 in the same direction as the persistent positive VPD forecast bias; live indoor climate is fresh and still in active VENTILATE cooling with fog/mister assist. No cosmetic override justified; retain sticky wet assist and monitor recovery. Resolved 13:44 MDT.
Forecast deviation	14:14	FORECAST_DEVIATION	acked	Acknowledged: Observed 67.4F is the outdoor/weather stream, while fresh indoor climate is 87.9F, VPD 1.81, dew margin 15.6F in VENTILATE. History confirms outdoor 67.4F with indoor warming 83.4→87.4F. Both fans, vent, fog, and center mister are already active; no marginal tactical write is justified. Classify as forecast/nowcast error or weather shift, not equipment failure. Semantic retrieval was attempted but unavailable due missing OPENAI_API_KEY; no tuning made. Resolved 14:15 MDT.
Forecast deviation	14:43	FORECAST_DEVIATION	acked	Acknowledged: Forecast deviation is same-direction forecast overshoot, not a controller fault or new regime. Fresh indoor climate is 83.1F, VPD 1.20, RH 69%, dew margin 11.2F; SEALED_MIST_FOG is active and relays are off only after recent fog/mister dwell. Keep sticky wet-assist posture; no tunable change. Resolved 14:44 MDT.
Peak Stress	15:01	TRANSITION	action_completed	Delivery recorded without a public plan write. Resolved 15:01 MDT.
Forecast deviation	15:14	FORECAST_DEVIATION	acked	Acknowledged: FORECAST_DEVIATION is a forecast/nowcast miss, not a controller miss: outdoor temp held at 67.4F versus 90.8F forecast across 19:00-21:00Z, while indoor response is active and saturated (VENTILATE, vent+fan1+fan2+fog, center mister). No cosmetic tunable change; retrieval also unavailable due missing embedding credential. Resolved 15:14 MDT.
Forecast deviation	15:44	FORECAST_DEVIATION	acked	Acknowledged: Live outdoor telemetry is fresh and sustained at RH 58.9% / VPD 0.94 versus forecast RH 22% / VPD 3.85, matching the established positive forecast-overshoot bias; this is a forecast error/late weather catch-up, not a controller fault. Indoor response is already saturated and appropriate: VENTILATE with vent, both fans, fog, and mister_center active; no marginal tactical write. Indoor remains hot/dry (86.5F, VPD 1.77) with healthy 15.3F dew margin, so retain active wet assist and monitor. Resolved 15:45 MDT.
Forecast deviation	16:13	FORECAST_DEVIATION	acked	Acknowledged: Acknowledged: fresh MCP climate/history confirm a sustained outdoor 67.4°F miss versus 91.9°F forecast, same direction as +4.7°F warm bias but far larger. Indoor is 82.2°F, VPD 1.13 kPa, dew margin 10.6°F; all relays are off after recovery and no equipment fault is indicated. No tunable change: do not unwind sticky wet assist while indoor VPD remains above the active high edge; current state has no marginal actuator benefit... Resolved 16:15 MDT.
Forecast deviation	16:44	FORECAST_DEVIATION	acked	Acknowledged: Forecast deviation is a forecast error, not a live controller miss: current VPD is 1.05 kPa, dew margin 10.2F, mode IDLE, and all relays are off. No tunable change is justified; avoid adding moisture while conditions are safe and near the served edge. Resolved 16:44 MDT.
Forecast deviation	17:44	FORECAST_DEVIATION	acked	Acknowledged: No climate write warranted. Live indoor VPD is 0.98 kPa (0.94 at trigger), just below the 0.99 high edge; temp 80.1F and dew margin 9.9F are safe. All climate relays are off and mode is IDLE, so no equipment fault or marginal actuator headroom is present. Forecast VPD 3.4 kPa overshot reality in the same direction as the established positive VPD forecast bias; classify as forecast calibration miss/catch-up, not regime change. Leave current moisture posture unchanged... Resolved 17:45 MDT.
Decline	18:24	TRANSITION	acked	Acknowledged: No tunable change: decline recovery is not complete. VPD is 1.31 kPa above the active 0.99 high edge, while dew margin is healthy at 13.5F; vent+fan2 are active. Current engage 1.6 kPa, pulse gap 45s, and fog escalation 0.4 are already conservative/default, so there is no aggressive midday posture to unwind yet. Resolved 18:25 MDT.
Forecast deviation	18:44	FORECAST_DEVIATION	acked	Acknowledged: Forecast VPD miss is lower than forecast in the known overshoot direction: observed 0.94 vs 2.97 kPa. Indoor VPD is 1.18 above active 0.99 high edge with healthy 12.4F dew margin; VENTILATE has vent, fan1, and fog active. No marginal tunable benefit; outdoor telemetry is stale/null. Semantic retrieval unavailable because OPENAI_API_KEY is missing; no climate change written. Resolved 18:44 MDT.
Forecast deviation	19:14	FORECAST_DEVIATION	acked	Acknowledged: Wind forecast miss only: observed 3.13 mph / gust 4.79 vs forecast 16.4 / 27.1. Fresh indoor climate is 79.0F, VPD 0.95, dew margin 9.8F, controller IDLE; no controller-attributable miss or marginal tuning benefit. Outdoor fields are null/stale, so no weather-policy change.

Compliance was moderate with VPD weaker than temperature; execution fidelity was poor because intended tactical changes were frequently missed or held at existing values. Utilities were unavailable, so cost impact could not be graded. Score: 6/10

Hypothesis

Testing: Validate live-VPD-gated dawn taper before the hot-dry ramp; compare VPD compliance with prior forecast-first escalation. Expected outcome: Keep dew-risk at 0h, clear the current VPD edge after the short bridge, and reduce controller-attributable VPD-high time before the 12:00-17:00 peak.

Safety held; VPD remained the weaker axis. Utilities unavailable. Score: 6/10

Hypothesis

Testing: Live-VPD gate: restrain dawn wetting, then compare peak VPD compliance and water duty with forecast-first escalation. Expected outcome: Keep dew margin at least 8F and VPD-low stress at 0h; improve VPD compliance versus yesterday’s 68.7% despite structural heat limits.

vpd_highhigh · 2026-09-06T12:00:00-06:00 to 2026-09-06T19:00:00-06:00

Live-VPD-gated vent-mist assist; fog 0.15 in safe hours; taper after measured recovery.

heathigh · 2026-09-06T13:00:00-06:00 to 2026-09-06T18:00:00-06:00

Pre-cool and use thermal venting; avoid sealed high-temperature humidity trapping.

Parameter rationale

mister_engage_kpa1.6 → 1.25; Dawn VPD is 0.72; corrected afternoon VPD peaks about 3.18 kPa.

Start wet assist only after live VPD crosses the edge, limiting dawn overshoot.

fog_escalation_kpa0.4 → 0.15; Forecast 92F, 20% RH and 773 W/m2; firmware fog and dew gates still apply.

Bring bounded fog earlier during the dry peak while retaining safety.

mister_pulse_gap_s45.0 → 22.0; Dry peak spans 13:00-16:00 with corrected VPD above 3 kPa and dew margin 9.4F.

Increase bounded evaporative duty, then taper after measured VPD recovery.

Testing: Test recovery-gated sunset taper after a hot/dry day, comparing edge recovery against overnight VPD-low overshoot. Expected outcome: Keep dew margin at least 8F, hold VPD-low stress to 0.5h or less, and avoid unnecessary overnight fog or relay churn.

Hot dry day ended with live VPD 1.04 and 11F dew margin; forecast drops into a cool humid trough overnight.

vpd_highmedium · 2026-09-06T19:25:00-06:00 to 2026-09-06T21:00:00-06:00

Keep wet assist available near the edge; taper only after measured VPD clears 0.99.

vpd_lowmedium · 2026-09-07T02:00:00-06:00 to 2026-09-07T07:00:00-06:00

Suppress mist and fog duty, preserve an 8F dew floor, and avoid rapid vent cycling.

Parameter rationale

mister_pulse_gap_s45.0 → 60.0; VPD falls from 1.63 at 20:00 to 0.32-0.52 from 02:00-07:00.

Allow a brief edge bridge, then reduce mist re-firing and VPD-low overshoot.

vpd_watch_dwell_s60.0 → 90.0; Forecast VPD drops quickly from 1.63 at 20:00 to 0.54 at 22:00.

Avoid short sealed-mist cycles during the falling-VPD handoff.
