Forecast deviation08:19FORECAST_DEVIATIONackedAcknowledged: FORECAST_DEVIATION reviewed: observed RH is much higher than forecast (about 65% vs 33%), but this is the same direction as recent RH/VPD forecast bias where Open-Meteo overstates dryness. Live greenhouse is not in a moisture stress miss: 67.6F, VPD 1.03 kPa inside the 0.72-1.27 band, RH 56%, dew margin 16.4F, mode VENTILATE. Equipment state is coherent for mild temperature cooling (vent open, fan2 on; heaters, fog, and misters off)... Resolved 08:19 MDT.
Solar peak planning checkpoint13:00SOLAR_MAXackedAcknowledged: SOLAR_MAX check: live solar 1032 W/m² is tracking the forecast peak after known solar-overshoot calibration; house is inside band at 82.7F and 1.32 kPa VPD with 12F dew margin, controller IDLE/resource, and the active SUNRISE plan already has aggressive peak-afternoon moisture/cooling posture in place. No tunable change warranted. Resolved 13:00 MDT.
Peak Stress14:59TRANSITIONackedAcknowledged: Peak-stress checkpoint is tracking the active SUNRISE plan. Live climate is near the upper band but controller is already in VENTILATE with wet/fog assist active: 85.1F vs 85F high, VPD 1.54 vs 1.38 high, dew margin 12.9F, vent+fan1+fog+center mister on. Existing setpoints are already at the aggressive hot-dry posture: fog_escalation_kpa 0.15, mister_engage_kpa 1.23, mister_all_kpa 1.38, gap 18s, pulse_on 90s, budget 300 gal, direct-wet override enabled...

Validating previous cycle: iris-20260604-0533

Previous hypothesis: SUNRISE plan for Thursday 2026-06-04. Yesterday scored 59.7: both-axis 53.0%, temp 76.6%, VPD 58.0%, with VPD the bottleneck and stress split across heat 5.47h, VPD-high 5.17h, and VPD-low 4.65h. Cost was low at USD 2.02 versus USD 3.17 7-day average, driven by runtime electric and water, with no gas. I evaluated the short SUNSET and MIDNIGHT handoff as safety-preserving but not clean: iris-20260603-2026 scored 3 vs anchor 1 and iris-20260604-0015 scored 4 vs anchor 1; the gap is because I credited clean dew safety and no temp stress, while the anchor correctly penalized guardrail/short-window compliance. Today I will plan anchor-first: humid dawn suppression only until live VPD recovers, then direct guardrail-aware band-coupled moisture before the 09:00-22:00 severe dry ramp… Result: Revised anchor-aligned grade. Although daily score improved and dew/cost/VPD-low outcomes were safe, the deterministic anchor is more appropriate because the plan window was guardrail-dirty: 318 guardrail events, 62 held VPD-high guardrail events, and unresolved sunset VPD-high/no-moisture-assist. Treat this as a partial safety-preserving reset, not a clean compliance win. Score: 2/10

Hypothesis

Testing: Test whether a MIDNIGHT reset that stays guardrail-clean while wetting is time-gated, then opens full band-coupled assist before 09:00, avoids another no-moisture-assist dry-ramp failure. Expected outcome: By sunrise: dp-risk remains 0h and no added VPD-low carryover. By Friday sunset if this fallback governs: VPD-high remains the bottleneck but no VENTILATE no-moisture-assist alert persists through the dry shoulder, mister/fog guardrail holds fall versus 310/125 in the SUNSET shoulder, and cost stays under about USD 5 unless severe VPD recovery requires the full 300 gal budget.

At midnight the house is still hot/dry: 70F, VPD 1.57 kPa, VENTILATE, 27F dew margin, vent+both fans, wet/fog blocked by time gates. Friday ramps to 90-91F, RH 13-17%, VPD 3.4-4.3 kPa, solar near 900 W/m2.

Expected stress windows

vpd_highmedium · 2026-06-05T00:16:00-06:00 to 2026-06-05T05:30:00-06:00

Keep moisture thresholds band-coupled and guardrail-clean even though direct wet/fog are time-gated; rely on ventilation for temperature until activity starts.

vpd_highhigh · 2026-06-05T08:30:00-06:00 to 2026-06-05T22:30:00-06:00

Before the dry ramp, restore full band-coupled wet assist: engage near high+0.05, all-zone near +0.25, fog 0.15 in the fog window, high duty, and 300 gal budget.

heathigh · 2026-06-05T10:30:00-06:00 to 2026-06-05T19:30:00-06:00

Use solar cooling lead and all-fan readiness while accepting physically limited hot misses near 90F.

Parameter rationale

mister_pulse_gap_s41.25 → 30.0; Current VPD is 0.39 kPa above high and Friday RH falls to 13-17% with VPD above 3 kPa.

Stop fighting the VPD-high moisture guardrail and keep mist duty available once the activity window opens.

fog_escalation_kpa0.2 → 0.15; Severe dry stress overlaps the 07:00-17:00 fog window with safe dew margin.

Allow PR-A vent-fog assist during hot-dry VENTILATE instead of waiting for extreme VPD.

mister_water_budget_gal220.0 → 300.0; Friday forecast is severe hot-dry and yesterday's VPD compliance was only 33.9% despite acceptable cost.

Prevent budget clipping during the highest-value dry-recovery window.

cool_stage2_over_high_f1.875 → 0.5; Solar rises near 900 W/m2 and outdoor temp reaches 90-91F by afternoon.

Bring fan2/all-fan cooling nearer the high edge before heat and VPD-high pair.

direct_wet_stress_min_dew_margin_f13.0 → 8.0; Midday dry heat widens dew margin while VPD-high threatens Vandas and east seedlings.

Permit safe dry-stress direct wetting during the daytime window while keeping stricter overnight floors.

Validating previous cycle: iris-20260604-2027

Previous hypothesis: SUNSET plan for 2026-06-04. Today underperformed: score 46.2 vs 54.8 7d average, both-axis compliance 37.9%, temp 80.5%, VPD 39.8%; VPD was the bottleneck with both VPD-low overcarry and live VPD-high at sunset. I evaluated iris-20260604-0533 at 3/10 vs anchor 1 because dew safety and low cost deserve limited credit, but the anchor is correct that 747 guardrail events, 30 held events, and a current VENTILATE VPD-high/no-moisture-assist alert make it guardrail-dirty. Retrieved lessons 135/105/131/114 say not to unwind by clock while live VPD remains above band with healthy dew margin. Tonight therefore keeps a short band-coupled recovery shoulder, then gradually raises dew safety/resource sensitivity overnight, and restores a dry-ramp fallback after sunrise if the next plan is delayed. Result: SUNRISE evaluation for Friday 2026-06-05 using yesterday scorecard and plan-window context. Daily score was 51.7, both-axis compliance 43.7%, temp compliance 54.1%, VPD compliance 46.1%; VPD was the bottleneck. Stress was dominated by VPD-high at 12.53h, with heat also high at 10.70h and almost no VPD-low at 0.03h. Dew safety held (min margin 8.4F, dp-risk 0h) and cost was acceptable at USD 2.46, below the USD 2.92 7d average, but the plan’s main severe dry-ramp hypothesis failed: despite band-coupled posture, VPD-high and VENTILATE/no-moisture-assist recurred into the evening and guardrail events remained material. Treat as safety-preserving but not compliance-successful; score kept near the deterministic anchor. Score: 1/10

New finding: On severe hot-dry days, low cost and dew safety are not enough if VPD-high and VENTILATE/no-moisture-assist persist into sunset; keep moisture band-coupled through observed VPD recovery and score guardrail-dirty plans near anchor. → Added to Lessons Learned

Hypothesis

Testing: Earlier guardrail-clean band-coupled wet assist plus an observed-recovery evening shoulder should reduce VPD-high/no-moisture-assist without repeating VPD-low overcarry. Expected outcome: Target Friday score 45-55 despite structural heat; VPD-high under 6h, VPD-low under 2h, dp-risk 0h, cost near or below USD 4.50, water use allowed to rise toward 200-300 gal if it buys VPD compliance.

vpd_highhigh · 2026-06-05T09:00:00-06:00 to 2026-06-05T23:00:00-06:00

Guardrail-clean band-coupled wet assist: engage near high+0.05, all-zone +0.20-0.25, fog 0.15-0.20 during safe fog window, high mist duty, and 300 gal budget.

heathigh · 2026-06-05T10:30:00-06:00 to 2026-06-05T20:00:00-06:00

Strong solar cooling lead and all-fan readiness; accept structural hot misses when outdoor approaches/exceeds served high edge.

vpd_lowlow · 2026-06-06T02:00:00-06:00 to 2026-06-06T07:00:00-06:00

After evening dry recovery, raise dew floor/resource sensitivity and widen duty to avoid wet carryover into the cool predawn.

Parameter rationale

mister_water_budget_gal180.0 → 300.0; Friday forecast has RH 11-15% and VPD 3.5-4.4 kPa from noon through evening; yesterday VPD compliance was only 33.7% despite safe dew.

Prevent water budget from clipping the highest-value VPD recovery windows while dew margin remains safe.

mister_pulse_gap_s41.25 → 18.0; Dry-ramp VPD rises above band by 09:00 and remains severe into the evening.

Increase evaporative recovery during peak VPD-high without lengthening pulse-on further.

fog_escalation_kpa0.2 → 0.15; Severe VPD-high overlaps the 07:00-17:00 fog window and dawn dew margin is 14.7F.

Allow PR-A vent-fog assist during hot-dry VENTILATE while firmware gates block unsafe fog.

direct_wet_stress_min_dew_margin_f14.0 → 8.0; Midday and evening dry heat should keep dew margin wide while VPD-high threatens center Vandas and east seedlings.

Permit dry-stress direct wetting during safe daytime/evening recovery instead of producing no-moisture-assist alerts.

mister_engage_kpa1.23 → 1.23; Current vpd_high is 1.18 kPa, so band-coupled S1 eligibility is high+0.05.

Keep S1 mist/vent-mist assist eligible and avoid conservative-threshold guardrail holds.

Reflection

Validating previous cycle: iris-20260605-0533

Previous hypothesis: SUNRISE plan for Friday 2026-06-05. Yesterday was safe but compliance-poor: daily score 41.9, both-axis 32.0%, temp 68.0%, VPD 33.7%, with VPD the bottleneck and stress split across heat 7.47h, VPD-high 7.67h, and VPD-low 7.80h. I evaluated iris-20260604-0533 at 3/10 versus anchor 1: I gave limited credit for 0h dew risk and acceptable cost, while the anchor correctly penalized 747 guardrail events and 30 held guardrail events. Today is a more severe hot-dry ramp: VPD exceeds band by 09:00, raw VPD 3.5-4.4 kPa from noon through evening, RH 11-15%, peak temp 91F, and solar near 900 W/m2. Retrieved lessons 131/134/128/105 say to keep dawn guarded only while VPD is in band, then run guardrail-clean band-coupled moisture with fog 0.15-0.20, high mist duty, 300 gal budget, and no clock-only evening unwind until observed VPD recovery… Result: MIDNIGHT evaluation of the SUNSET recovery plan. Safety goals held: dew-point margin stayed wide (current ~18F, day dp-risk 0h), VPD-low did not appear in the midnight window, and cost remained acceptable. The compliance/recovery hypothesis did not meet its main objective by the midnight boundary: current house is still in VENTILATE at ~71F vs 67F high and VPD ~1.23 kPa vs 1.18 high; the window scorecard for iris-20260605-2027 shows 0.0% both-axis/temp/VPD compliance and score 19.6, and the prior VENTILATE VPD-high/no-moisture-assist alert remains active. The observed-recovery shoulder improved VPD from the sunset ~1.97 kPa state but did not clear the band before the planned taper. Score is deliberately near anchor because safe dew/low VPD-low are necessary but not sufficient when the plan remained guardrail-dirty and did not recover compliance. Score: 2/10

Hypothesis

Testing: Test whether an observed-recovery SUNSET shoulder followed by a guarded overnight taper can reduce live VPD-high without recreating VPD-low, while preserving a severe dry-ramp fallback for Saturday. Expected outcome: By sunrise: dp_risk_hours remains 0, VPD-low stays under 0.5h, and VPD-high is materially lower than the live sunset state. If SUNRISE is delayed, Saturday fallback should keep VPD-low near zero while making wet/fog assist available before the 09:00 dry ramp.

Sunset starts hot/dry: 80F, VPD ~1.97 kPa, VENTILATE, dew margin 23F, wet/fog blocked by dusk gates. Overnight cools into the upper 50s with VPD falling near band, then Saturday ramps severe hot-dry near 95F/8% RH and high solar.

Expected stress windows

vpd_highmedium · 2026-06-05T20:27:00-06:00 to 2026-06-06T00:30:00-06:00

Keep short observed-recovery shoulder: band-coupled mister thresholds, moderate duty, healthy dew floors, and no clock-only unwind while VPD remains high.

vpd_highhigh · 2026-06-06T08:30:00-06:00 to 2026-06-06T21:00:00-06:00

Missed-SUNRISE fallback restores severe dry-ramp posture: engage near high+0.05, all-zone +0.20-0.25, fog 0.15 in the safe fog window, high duty, and 300 gal budget.

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

Use strong solar cooling lead and all-fan readiness; accept structural hot misses once outdoor approaches or exceeds the served high edge.

Parameter rationale

mister_engage_kpa1.23 → 1.26; Live VPD is ~0.75 kPa above the high band with 23F dew margin; retrieved lessons 135/105/131 say recovery must stay band-coupled until observed VPD recovery.

Keep S1 mist/vent-mist assist eligible during the evening shoulder instead of creating no-moisture-assist alerts.

mister_all_kpa1.43 → 1.46; Whole-house and east-zone VPD remain above band at sunset; Saturday repeats severe dry pressure.

Keep all-zone rotation available before VPD drifts farther above band, while tapering duty after midnight.

mister_pulse_gap_s28.0 → 35.0; Evening recovery needs moisture but overnight cooling raises wet carryover risk.

Provide moderate recovery without recreating VPD-low or dew risk overnight.

fog_escalation_kpa0.2 → 0.15; Saturday severe dry ramp overlaps the 07:00-17:00 fog window; dew safety is currently strong.

Allow PR-A vent-fog assist during hot-dry VENTILATE if the SUNRISE cycle is delayed.

direct_wet_stress_min_dew_margin_f10.0 → 12.0; Night cooling follows a wet recovery shoulder; dew margin is safe now but should be guarded before pre-dawn.

Avoid condensation/leaf-wetness risk while still allowing current high-VPD recovery.

mister_water_budget_gal260.0 → 300.0; Saturday forecast reaches 95F, RH 8%, VPD >5 kPa; today’s 79 gal mister water did not clear VPD-high.

Prevent water-budget clipping during Saturday’s highest-value VPD recovery window.

cool_stage2_over_high_f0.0 → 0.5; Saturday heat warning peaks near 95F with high solar and today had 6.83h heat stress.

Keep fan2/all-fan readiness near the high edge during the dry-ramp fallback.
