Forecast deviation07:49FORECAST_DEVIATIONackedAcknowledged: FORECAST_DEVIATION assessed: outdoor temperature is ~8.4F hotter than prior forecast, but current greenhouse climate remains inside dispatcher bands (75.7F vs temp_high 77.3F; VPD 0.86 kPa vs vpd_high 1.0; dew margin 9.6F) and all equipment is correctly idle. This is a live near-term forecast warm bias/clear-solar ramp, not an equipment fault or data gap; active severe hot-dry plan already has compliance-first wet/fog posture, so no extra tunable change is justified before an actual band miss. Resolved 07:50 MDT.
Forecast deviation10:16FORECAST_DEVIATIONackedAcknowledged: FORECAST_DEVIATION assessed with live climate/equipment: deviation is mainly forecast dry/wind overstatement in the same direction as historical bias; current VPD remains modestly above band but existing plan is already compliance-first with aggressive band-coupled wet/fog assist, dew margin is safe, and no equipment fault is indicated. No tunable change needed. Resolved 10:17 MDT.

Solar peak planning checkpoint13:05SOLAR_MAXackedAcknowledged: SOLAR_MAX no-change: live solar is very high (1033 W/m2) and above the near-term forecast, but indoor average VPD is currently 1.17 kPa, just below the active 1.22 kPa high edge, dew margin is healthy at 9.8F, and the controller is already in SEALED_MIST_S1 with wet assist active. The existing sunrise plan has an imminent 13:30 aggressive hot-dry waypoint plus current aggressive pulse/fog support (16s gap, min_fog_off ~32s, direct wet and fog stress extensions enabled), so a one-shot tunable nudge now... Resolved 13:06 MDT.
Forecast deviation13:17FORECAST_DEVIATIONackedAcknowledged: FORECAST_DEVIATION assessed: deviation is isolated wind-gust forecast miss, not stale/missing forecast data and not a live greenhouse control miss. Current climate is 86.9F, VPD 1.34 kPa, RH 72%, dew margin 10.2F, outdoor 85F/28% RH, mode IDLE; all relays/fog/misters/vent off. Existing active severe hot-dry/VPD posture remains appropriate; no tunable change needed for lower-than-forecast wind gusts alone. Resolved 13:18 MDT.
Forecast deviation13:35FORECAST_DEVIATIONackedAcknowledged: FORECAST_DEVIATION assessed: observed VPD is lower/more humid than forecast, matching the known positive VPD forecast bias rather than a new hot-dry regime. Live climate is currently inside/near band (84.8F, VPD 1.16 kPa vs vpd_high 1.22, RH 73%, dew margin 9.7F) and equipment is safely IDLE/all relays off, so no tunable change is warranted. Resolved 13:36 MDT.
Forecast deviation13:53FORECAST_DEVIATIONackedAcknowledged: FORECAST_DEVIATION assessed: wind speed forecast was high by ~16 mph, but live climate shows expected hot/dry stress rather than a new controllable regime. House is 87.7F / 1.69 kPa VPD with healthy 13.2F dew margin, VENTILATE active, vent+fan2+fog+center mister running. Existing compliance-first wet/fog posture is already serving the live temp+VPD miss; no additional tunable change needed. Resolved 13:54 MDT.
Forecast deviation14:45FORECAST_DEVIATIONackedAcknowledged: FORECAST_DEVIATION no tuning: observed VPD is lower/more humid than the raw forecast in the same direction as the known positive VPD forecast bias; live climate is near band edge and existing hot-dry posture is active with vent+both fans+fog, dew margin safe. Resolved 14:45 MDT.

Forecast deviation15:03FORECAST_DEVIATIONackedAcknowledged: FORECAST_DEVIATION assessed: observed wind is much lower than forecast, but climate telemetry is fresh and the greenhouse is already in VENTILATE with wet/fog assist active. Current miss is the known severe hot-dry VPD pressure, not a new equipment fault or stale forecast-data gap; no additional tuning beyond the active compliance-first posture is justified. Resolved 15:04 MDT.
Forecast deviation15:55FORECAST_DEVIATIONackedAcknowledged: FORECAST_DEVIATION assessed as known forecast dry/VPD positive-bias catch-up rather than a new regime or equipment fault. Live climate is hot/dry but already being served by active hot-dry posture: 85.7F, VPD 1.56 kPa vs vpd_high 1.18, RH 67%, dew margin 13.3F, VENTILATE with vent/fan2/fog and west mister. Current tunables are already band-coupled/aggressive (fog_escalation 0.15, mister_engage 1.24 near vpd_high+0.06, mister_all 1.44 near +0.26, pulse gap 16s, direct-wet/fog stress extension enabled)... Resolved 15:55 MDT.
Forecast deviation16:30FORECAST_DEVIATIONackedAcknowledged: FORECAST_DEVIATION reviewed: observed wind/gust are far lower than forecast, but live climate is already in controller-managed VPD recovery with temperature below high band, dew margin safe, wet assist active, and no equipment fault. No tactical tunable change needed. Resolved 16:30 MDT.
Forecast deviation18:32FORECAST_DEVIATIONackedAcknowledged: FORECAST_DEVIATION reviewed: observed VPD is below the raw forecast in the same direction as the known positive VPD forecast bias, and live climate is now in/near band with safe dew margin and no equipment fault. No tuning needed. Resolved 18:42 MDT.
Decline19:35TRANSITIONackedAcknowledged: Decline transition checked with MCP climate, equipment, active plan, and setpoints. Current house is still VPD-high (78.3F, VPD 1.28 kPa vs vpd_high 1.0) with healthy dew margin 12.4F and no VPD-low/dp-risk signal. Equipment is vent+fan1+fan2 active, fog/misters/heaters off. Existing plan already carries evening recovery posture and has a 21:30 taper waypoint, so no immediate tunable change is warranted; avoid unwinding wet assist while observed VPD remains above band. Resolved 19:35 MDT.
Forecast deviation19:42FORECAST_DEVIATIONackedAcknowledged: FORECAST_DEVIATION reviewed: current VPD is much lower than raw forecast and in the same direction as the known positive VPD forecast bias; no live regime-change tuning needed. Existing compliance-first moisture posture remains appropriate; no setpoint changes made. Resolved 19:42 MDT.

Reflection

Validating previous cycle: iris-20260616-0532

Previous hypothesis: SUNRISE plan for Tuesday 2026-06-16. I evaluated the overnight portion of iris-20260616-0020 at 8/10; the deterministic anchor was 6, with no deviation warning. The completed pre-sunrise segment scored 84.3 with 100% temp compliance, 86% VPD compliance, 0.73h VPD-high stress, no heat/cold/VPD-low stress, and about USD 0.216 window cost. That supports the guarded pre-dawn posture, but guardrail/readback events mean I should keep the new plan inside bounded ClimateIntent instead of pushing individual rows. Yesterday 2026-06-15 scored 71.4: VPD was the bottleneck at 76.3% vs 93.7% temp compliance, and VPD-high dominated stress at 5.52h vs 1.47h heat. Cost was USD 6.53, above the 7d average USD 4.05, driven by water (USD 4.75, 981 gal total) plus electric cooling/fog (USD 1.78), not gas; mister-only water was 143 gal, so total downstream water remains a separate watch item… Result: Early completed segment before replacement: current daily partial score 56.4 with 45.8% compliance, 97.2% temp compliance, 45.8% VPD compliance, 0.65h VPD-high stress so far, no heat/cold/VPD-low stress, dp margin minimum 7.7F and no dp-risk hours. The immediate window score row was similar: 56.4, 45.8% compliance, 0.02h VPD-high in the scoped first segment and negligible cost. The severe-day hypothesis remains largely untested because the main 07:00-22:00 hot-dry window has not occurred yet. The plan did preserve dew safety and temperature, and current controller proof shows VENT_COOL_MIST_ASSIST with wet allowed and south mister active. However VPD is already above band at 1.26 kPa with large zone spread, the house is in VENTILATE at 01:00, and an open vent_vpd_moisture_gap alert plus multiple recent setpoint confirmation/missed transition alerts mean realization risk remains high. Score reflects safe but incomplete early execution, not a validation of the severe-day strategy. Score: 5/10

Hypothesis

Testing: Severe-day realization test: keep bounded ClimateIntent compliance-first, then judge success by realized wet-assist availability and VPD compliance, not by low water/cost alone. Expected outcome: For the Wednesday local day, target VPD compliance above 60% if physics and dispatcher realization allow, temp compliance above 75%, VPD-high below 6h, heat stress below 4h, no VPD-low carryover, dp-risk under 0.5h, and explicit follow-up on any vent/moisture gap or setpoint divergence alerts.

Result: Evaluated at SUNRISE before replacement, covering the completed early segment only. Current-day partial/window score is 55.3 with 45.1% compliance, 94.8% temp compliance, 45.4% VPD compliance, about 0.55h VPD-high stress in the scoped segment, no heat/cold/VPD-low stress, dp margin minimum 7.7-8.2F, no dp-risk hours, and low early cost (~USD 0.19 scoped / USD 0.57 partial). The plan preserved temperature and dew safety but did not prove the severe-day hypothesis yet because the 07:00-22:00 hot-dry window has not occurred. Realization risk remains the primary concern: recent resolved vent_vpd_moisture_gap and setpoint_unconfirmed alerts plus missed/held transitions show wet/fog intent may not always reach firmware. Score is mid-low because VPD compliance is already the bottleneck even before peak stress, while safety and temperature were good. Score: 5/10

New finding: On severe hot-dry sunrise cycles, a safe early segment should not be treated as validation of the full wet/fog strategy; keep the plan compliance-first, but score early replacements mainly on realization evidence (vent-mist/fog availability and setpoint confirmation), not resource savings or absence of heat stress before solar peak. → Added to Lessons Learned

Hypothesis

Testing: Severe hot-dry realization check: hold wet/fog assist open through Wednesday and judge success by VPD compliance plus vent-mist/fog availability, not by low water/cost alone. Expected outcome: For the remainder of Wednesday, target temp compliance >75%, VPD compliance >60%, VPD-high stress below 8h despite severe forecast, heat stress below 4h if physically possible, no VPD-low carryover, dp-risk under 0.5h, and resolution or operator visibility on vent_vpd_moisture_gap/setpoint confirmation issues.

Result: Completed Wednesday governed window scored 39.2 overall with 27.4% compliance, 95.1% temp compliance, only 27.9% VPD compliance, about 0.89h heat stress and 7.05h VPD-high stress in-window; full-day score was 48.9 with 41.3% compliance, 92.6% temp compliance, 42.1% VPD compliance, 13.6h VPD-high, 1.73h heat, cost USD 3.14, water 343 gal, mister water 222 gal, dp margin min 7.1F and no dp-risk hours. The forecast/hypothesis correctly identified hot-dry high-solar VPD stress and preserved dew/temperature safety, but the primary compliance goal failed badly: VPD compliance missed the >60% target, VPD-high was not reduced enough, and recent vent_vpd_moisture_gap plus setpoint confirmation/mismatch alerts show wet/fog intent realization remained the main failure mode. Low cost/water and safe dew are not adequate success criteria while VPD stays high. Score: 3/10

New finding: On 85-95F high-solar days with RH below about 20%, even band-coupled moisture/fog intent can fail if setpoint realization and vent-mist assist availability are unstable; score these plans primarily on VPD compliance and realization proof, and keep resource sensitivity low until VPD recovery is observed rather than treating low water/cost or dew safety as success. → Added to Lessons Learned

Hypothesis

Testing: Severe hot-dry realization check v2: keep wet/fog assist band-coupled through Wednesday peak and judge by VPD compliance plus vent-mist/fog availability/setpoint confirmations, not by low water/cost. Expected outcome: For Wednesday, target temp compliance >75%, VPD compliance >60%, VPD-high stress below yesterday’s 9.15h, heat stress below 4h if physically possible, zero VPD-low carryover, dp-risk ⇐0.5h, and fewer vent_vpd_moisture_gap/setpoint_unconfirmed repeats than the midnight plan.

Severe hot-dry Wednesday with forecast VPD positively biased but corrected VPD still severe. Current house is safe at 70.2F, VPD 0.63 kPa, RH 75%, dew margin 8.2F and IDLE; VPD is inside band now but will ramp quickly with clear solar. Context degraded: greenhouse planner playbook mirror missing, knowledge/lesson semantic retrieval requires OPENAI_API_KEY, validate-plan-coverage missing, and static site context missing.

Expected stress windows

vpd_highhigh · 2026-06-17T08:00:00-06:00 to 2026-06-17T22:00:00-06:00

Band-coupled wet assist: engage near vpd_high+0.05, all-zone near vpd_high+0.20, mist duty 50-60%, fog escalation 0.15 during safe fog/vent-mist windows, daily budget 300 gal, and wet cutoff through evening recovery.

heathigh · 2026-06-17T10:30:00-06:00 to 2026-06-17T20:00:00-06:00

Solar precooling with 60 min lead, low resource sensitivity and low-to-moderate relay churn penalty during ramp/peak; accept physically limited hot misses when outdoor approaches or exceeds served target while preserving vent-mist assist.

vpd_highhigh · 2026-06-18T09:00:00-06:00 to 2026-06-18T21:00:00-06:00

Thursday remains warm/dry; keep moisture band-coupled but slightly less aggressive than Wednesday, tapering only after observed VPD recovery.

vpd_highmedium · 2026-06-19T10:00:00-06:00 to 2026-06-19T21:00:00-06:00

Friday is cooler but dry/high-solar; use moderate band-coupled moisture and restore resource sensitivity after the peak.

Parameter rationale

mister_engage_kpa0.8 → 0.94; VPD rises above band by morning with RH 8-14% and solar near 930 W/m2; current dew margin is 8.2F and occupancy is empty.

Keep first-stage mist eligibility near the dispatcher VPD-high edge whenever wet/dew gates are safe, improving VPD compliance versus yesterday's 61.1% if realization holds.

mister_all_kpa1.9 → 1.09; Zone VPD spread exceeded 0.5 kPa in the last 3h and dry pressure will become whole-house; active lesson says all-zone assist must not lag on 900 W/m2 dry days.

Reduce localized dry outliers and avoid south-only under-response during peak VPD stress.

fog_escalation_kpa0.4 → 0.15; Heat/VPD overlap the 07:00-17:00 fog window and fog is the 7x moisture path; prior plans failed when vent-mist/fog realization was poor, not because water cost was high.

Reduce VPD-high stress below yesterday's 9.15h if fog and vent-mist assist are confirmed available.

mister_pulse_gap_s45.0 → 20.0; Yesterday cost and water were below 7d averages while VPD-high dominated stress, so resource clipping is the wrong lever during active dry misses.

Prevent resource optimization from spacing pulses too far apart during safe hot-dry VENTILATE.

mister_water_budget_gal300.0 → 300.0; Water use was not excessive yesterday relative to the 300 gal mister cap and 7d total water average; compliance remains primary.

Keep budget from becoming the limiting factor during VPD-high stress while monitoring total downstream water separately.

temp_hysteresis1.6 → 1.6; Dwell gate remains enabled and no cold stress occurred; heat misses today will be mostly physical under 94F outdoor temperature.

Avoid introducing temperature whipsaw while focusing changes on moisture availability.
