Solar peak planning checkpoint13:00SOLAR_MAXackedAcknowledged: No tunable change: live solar_w/solar_w_m2 are unavailable and lux is only 2105, so forecast peak is unconfirmed. VPD rose to 1.45 kPa but is now 1.06, temp 82.6F is below 83.2F high, dew margin 9.9F, and the active plan's live-gated afternoon posture remains appropriate. Retrieval was attempted but unavailable due missing OPENAI_API_KEY. Resolved 13:01 MDT.
Forecast deviation13:14FORECAST_DEVIATIONackedAcknowledged: No climate write: fresh indoor telemetry shows 83.8F, VPD 1.48, dew margin 14.0F, with SEALED_MIST_FOG/vent-mist response already active and relays just in pulse-off dwell. The 0.94 VPD/0 solar deviation is an outsized forecast/nowcast miss in the same high-direction bias, not evidence of equipment failure; outdoor fields are stale/null. Unified retrieval failed on missing OPENAI_API_KEY, so retain the current safe posture rather than make a cosmetic override. Resolved 13:15 MDT.
Forecast deviation14:15FORECAST_DEVIATIONackedAcknowledged: No tunable change: observed forecast-scope VPD 0.94 was far below forecast 3.87, consistent with the durable positive forecast VPD bias and stale outdoor telemetry, not a confirmed regime shift. Indoor climate is still hot/dry (85.5F, VPD 1.63, dew margin 15F) and the controller is already serving vent+fan1+fan2+fog; no marginal threshold benefit. Retrieval also failed because embedding credentials are unavailable. Resolved 14:15 MDT.
Peak Stress15:00TRANSITIONackedAcknowledged: Peak-stress action was indicated (86.5F and VPD 1.72 kPa above active edges with vent, both fans, fog, and healthy 14.9F dew margin), but mandatory semantic retrieval failed because OPENAI_API_KEY was unavailable. No tunable write was made; recorded explicit neutral fallback after one platform-request attempt and one canonical AI planning agent brief fallback. Resolved 15:01 MDT.
Forecast deviation15:14FORECAST_DEVIATIONackedAcknowledged: No climate-policy change: the deviation is outdoor/forecast-scope VPD (3.46 forecast vs 0.94 observed), in the same direction as the established +0.98 kPa forecast bias. Fresh indoor telemetry is still hot/dry (85.1F, 1.59 kPa) with healthy 14.0F dew margin, and the controller is already serving vent + fan2 + mister assist; fog is outside its 07:00-17:00 window. No marginal tunable benefit; monitor recovery. Resolved 15:15 MDT.
Forecast deviation17:15FORECAST_DEVIATIONackedAcknowledged: Observed outdoor VPD 0.94 versus forecast 3.01 is a large forecast/nowcast miss in the known positive-VPD-bias direction. Indoor telemetry is fresh and currently near the VPD high edge (1.04 kPa), dew margin is healthy (9.9F), controller is IDLE, and all relays are off after recovery. No marginal tunable change is justified; avoid cosmetic moisture writes. Resolved 17:15 MDT.
Forecast deviation17:45FORECAST_DEVIATIONackedAcknowledged: Wind deviation is a forecast miss/nowcast catch-up: observed 3.13 mph vs forecast 18.4 mph, with no established wind-bias calibration. Indoor telemetry is fresh and stable (81.9F, VPD 1.07 kPa, dew margin 10.3F, IDLE); all relays are off as appropriate. No controller-attributable miss or marginal benefit from tuning; acknowledge without climate-policy change. Resolved 17:45 MDT.
Decline18:23TRANSITIONackedAcknowledged: No change: live temp 80.5F is below the 83.2F high edge, VPD 1.01 kPa is near and falling toward the 0.99 high edge, controller is IDLE, and dew margin is healthy at 10.0F. Existing plan already tapers gap/fog by 21:00; no cosmetic override warranted. Semantic retrieval was unavailable due to missing OPENAI_API_KEY, so no tactical write was made. Resolved 18:24 MDT.

Safety and overnight recovery objective held, but many planned tactical values were missed or clamped, so effect attribution is weak. Score: 8/10

Hypothesis

Testing: Test live-VPD-gated overnight taper followed by bounded morning vent-mist assist under forecast uncertainty. Expected outcome: Keep overnight dew margin >=8F and VPD-low stress ⇐0.5h; reduce controller-attributable dry-edge time during the morning ramp without sealing above 85F.

The planned hot-dry posture reduced risk but forecast/telemetry overcalled the heat and dry ramp; this was partial success rather than full target attainment. Score: 7/10

New finding: When a hot-dry forecast is uncertain, live-VPD gating and bounded moisture assist are safer than fully pre-staging aggressive cooling; evaluate controller-attributable VPD-high time after the ramp before tapering. → Added to Lessons Learned

Hypothesis

Testing: Weekly test: live-VPD gating plus two hot-dry assist windows; compare VPD-high hours, dew risk, water, and wet-served action share. Expected outcome: Keep dew margin >=8F, VPD-low stress ⇐0.5h in troughs, and reduce controller-attributable VPD-high time by >=20% during live-confirmed dry windows; accept capacity-limited heat.

Previous hypothesis: Live-VPD-gated midnight recovery: preserve an 8F dew margin, taper wet assist only after measured recovery, then pre-cool and provide bounded vent-mist/fog assist for the forecast dry ramp. Outdoor telemetry is unavailable and forecast skill has been poor; live conditions override. Prior plan self-score 6 vs deterministic anchor 8 because forecast-mismatch and missed materialization limited the test. Result: Window score 69.9; temp compliance 60.7%, VPD compliance 68.6%; 2.11h total stress with 0.66h VPD-high and no cold/VPD-low/dew-risk hours. Dew margin stayed safe. Forecast overstated heat/dryness (predicted 90F/24% RH/721 W/m2; observed peak 67.4F proxy, indoor RH min 51%); 68 guardrail writes were missed, including fog, mist gap, hysteresis, and stage-2 cooling changes, so the experiment was only partially materialized. Score: 5/10

Hypothesis

Testing: Live-VPD gating: compare 09:00-19:00 wet-served share and VPD-high hours against yesterday; preserve >=8F dew margin. Expected outcome: VPD-high stress below yesterday’s 2.94h when forecast conditions materialize, zero dew-risk hours, and no relay-churn increase; heat overshoot may remain physics-limited.

Pre-cool and ventilate; accept capacity-limited heat while preserving VPD assist.

Parameter rationale

fog_escalation_kpa0.4 → 0.15; Corrected VPD 2.2-2.56 kPa, 09:00-18:00; fog safety gates remain active.

Earlier bounded fog during safe hot-dry VENTILATE without closing dew-margin protection.

mister_pulse_gap_s45.0 → 20.0; Forecast VPD exceeds 3.0 kPa from 12:00-18:00; current dew margin is 8.7F.

Increase bounded evaporative duty and reduce controller-attributable VPD-high time.

mister_engage_kpa1.6 → 1.25; Live VPD is 0.71 kPa at dawn; engage remains live-edge gated before the dry ramp.

Make wet assist available at the band edge without repeating dawn over-wetting.

The cool/humid overnight posture met its no-stress objective; utility cost fields unavailable, so resource efficiency could not be graded. Score: 9/10

Hypothesis

Testing: Overnight humid-trough guard: compare VPD-low hours and dew-risk with the prior sunset window while retaining live-edge recovery. Expected outcome: Zero dew-risk, no VPD-low overshoot attributable to wet assist, fewer mister/relay transitions, and live-edge recovery only if measured VPD exceeds the high edge.

Cool humid overnight; forecast VPD 0.18-0.76, live VPD 0.94, dew margin 9.7F. Prior hot-dry plan scored 5 vs anchor 6 after forecast miss and missed writes.

Expected stress windows

vpd_lowhigh · 2026-09-07T21:00:00-06:00 to 2026-09-08T07:00:00-06:00

Suppress routine wetting; retain live-edge recovery and hold an 8F dew floor.

Parameter rationale

mister_pulse_gap_s45.0 → 60.0; VPD falls 0.76 to 0.18 by 06:00 with RH 69-90%.

Prevent VPD-low overshoot and reduce overnight mister re-firing.

vpd_watch_dwell_s60.0 → 90.0; VPD stays below the high edge after 21:00; current mode is IDLE.

Avoid short sealed-mist cycles during the humid trough.
