Solar peak planning checkpoint13:07SOLAR_MAXackedAcknowledged: SOLAR_MAX no-action: live solar is below/near the bias-corrected forecast peak, indoor temp and VPD are inside the dispatcher band (81.2F, VPD 1.09 vs vpd_high 1.22), dew margin is safe at 10.8F, and the active SUNRISE plan already has band-coupled wet/fog posture staged for the afternoon dry ramp.

Forecast deviation14:39FORECAST_DEVIATIONackedAcknowledged: FORECAST_DEVIATION assessed: observed solar is far below prior forecast due to cloud/thunderstorm nowcast shift, in the same broad direction as the known positive solar/VPD forecast bias but much larger. Live greenhouse is not in a control miss: 83.3F, VPD 1.13 kPa below vpd_high 1.21, RH 72%, dew margin 10.2F, ESP32 IDLE, all climate relays/wet assist off by demand.

Reflection

Validating previous cycle: iris-20260623-0537

Previous hypothesis: SUNRISE plan 2026-06-23. Previous plan iris-20260623-0136 evaluated 4/10 vs anchor 3: safe but too wet at dawn, and daytime dry-ramp response was not yet validated. Yesterday scored 72.5: temp 91.9%, VPD 70.9%, stress 8.7h dominated by 6.8h VPD-high plus 1.9h heat, cost USD 3.13 vs 7d USD 3.84. Retrieval degraded: knowledge_search and lessons_search failed for missing OPENAI_API_KEY; validate-plan-coverage and static site context are missing. Plan: dry out the orchid zone first, then use validated hot-dry mist/fog lessons during the 85F / VPD 2.8 / 868 W/m2 dry ramp. Result: SUNRISE partial-window evaluation before replacement. From 00:22-05:37 MDT the humid pre-dawn safety portion mostly succeeded: live climate is safe at about 68.3F, VPD 0.55 kPa, RH 77%, dew margin 7.6F, IDLE, no equipment running, and dp-risk remains 0h. However the window scorecard still shows low score/compliance so far (planner score 55.9, temp compliance 70.2%, VPD compliance 61.1%, 0.47h VPD-high and 0.36h heat in the scoped window), and several resolved setpoint confirmation plus vent_vpd_moisture_gap alerts indicate the moisture path was not consistently realized overnight. The main afternoon hot-dry hypothesis has not run yet, so this score is intentionally a partial pre-dawn grade. Yesterday’s complete-day score was 66.5 with temp compliance 99.9%, VPD compliance 66.2%, 7.93h VPD-high, 0.03h heat, 0h VPD-low/cold, dp-risk 0h, and cost USD 4.88 driven by water and electric; VPD-high remained the bottleneck despite safe dew margin. Score: 5/10

New finding: When a pre-dawn taper is safe but setpoint confirmations and vent-mist realization alerts appear before a hot-dry ramp, the next sunrise plan should keep the same dry-out-then-ramp strategy but make realization proof a primary success criterion; do not score biological success from intended thresholds alone. → Added to Lessons Learned

Hypothesis

Testing: Midnight dry-out then live-confirmed VPD recovery: protect the Vanda/orchid zone through humid pre-dawn, then restore wet/fog assist for the afternoon hot-dry ramp while watching realization alerts. Expected outcome: Today: dp-risk remains 0h, no cold/heat stress before sunrise, afternoon VPD-high stress under 5h if wet-assist realization succeeds, and total cost below USD 5.50 despite compliance-first water use.

vpd_highhigh · 2026-06-26T08:00:00-06:00 to 2026-06-26T20:00:00-06:00

Return to aggressive band-coupled wet/fog posture for the stronger Friday dry ramp.

Parameter rationale

mister_engage_kpa0.82 → 1.1; Humid pre-dawn RH near 90%.

Avoid needless orchid-zone wetting before sunrise.

mister_engage_kpa1.1 → 0.82; Noon live/forecast VPD rises above band.

Restore first-stage wet assist near the VPD high edge.

mister_all_kpa1.3 → 1.02; East/north dry outliers and afternoon VPD ramp.

Escalate beyond south-only pulses during dry stress.

mister_pulse_gap_s60.0 → 24.0; Hot dry peak with dew margin above 8F.

Reduce VPD-high hours without adding dew risk.

fog_escalation_kpa0.35 → 0.15; Dry peak overlaps 07-17 fog window.

Use the 7x fog path when misters cannot hold VPD.

mister_water_budget_gal180.0 → 260.0; VPD compliance is the bottleneck, not temperature.

Prevent budget clipping during afternoon recovery.

Validating previous cycle: iris-20260623-2042

Previous hypothesis: SUNSET overnight plan for Tuesday 2026-06-23. I evaluated iris-20260623-0537 at 5/10 while the deterministic anchor was 2; the +3 gap is intentional because biological safety and some compliance value were real (no dew-risk, no VPD-low/cold stress, safe handoff), while the anchor correctly penalized 872 guardrail events, 30 held events, 17 dispatched guardrail events, and 47 VPD-high guardrail events. Today’s bottleneck was VPD-high, not temperature: score 68.1, temp compliance 99.8%, VPD compliance 68.7%, 6.25h VPD-high, cost USD 5.13 vs 7d USD 3.36 driven mostly by total water. Tonight’s forecast flips to humid/cool: raw outdoor VPD 0.16-0.28 kPa from midnight to dawn, RH 85-92%, and current dew margin 8.9F… Result: SUNSET evaluation for the 2026-06-24 sunrise plan. The realization-gated dry-out-then-ramp hypothesis was partly successful but not clean. Today’s scorecard improved to 74.1 vs 7d 64.6, with temp compliance 91.5%, VPD compliance 76.4%, total stress 6.30h, and VPD-high still the main bottleneck at 4.63h plus 1.67h heat. Cost was controlled at USD 2.56 vs 7d USD 3.60, driven by electric USD 2.20 and water USD 0.36, with no gas; mister water was only 30 gal. Dew safety succeeded: dp_margin_min 6.9F and dp_risk 0h. The plan’s measurable target of VPD-high below 6h and dp-risk 0h was met on the daily view, but the scoped window scorecard remained weaker (planner 64.7, temp 75.6%, VPD 63.2%, heat 0.86h, VPD-high 2.38h), and many setpoint_unconfirmed/readback/missed transition alerts show the wet/fog realization proof criterion was not consistently met. Forecast conditions also differed from prediction: actual temperature was cooler and indoor humidity higher than predicted while solar was higher, so some success likely came from weather, not just tuning. Score: 5/10

New finding: On humid/cloudy recovery days after repeated hot-dry VPD-high stress, a plan can meet daily VPD-high and dew-safety targets while still failing the realization criterion because setpoint readbacks and guardrail/missed transition events prevent requested wet/fog posture from being reliably delivered. Score these plans as partial success and make readback/action-proof cleanup part of the next posture before increasing biological confidence. → Added to Lessons Learned

Hypothesis

Testing: Realization-gated dry-out-then-ramp: today’s test is whether reopening band-coupled wet/fog assist after live VPD rises reduces VPD-high hours below 6 while keeping dp-risk at 0h; success requires setpoint confirmations and no recurring vent_vpd_moisture_gap alerts, not just plan intent. Expected outcome: By sunset: dp-risk remains 0h, VPD-low stays near 0h, VPD-high stress improves from yesterday’s 7.93h toward under 6h despite the hot/dry ramp, heat stress stays below 2h unless physics-limited by 85-86F outdoor air, and total cost stays near or below USD 5.50 unless wet-assist realization requires more water.

Aggressive band-coupled wet/fog for stronger Friday dry ramp.

Parameter rationale

mister_engage_kpa0.96 → 0.95; Live VPD rising late morning after humid dawn.

Open S1 wet assist near the high edge without dawn wetting.

mister_all_kpa1.21 → 1.12; Afternoon VPD 2.2-2.8 kPa with east dry outlier.

Escalate beyond south-only pulses during dry stress.

mister_pulse_gap_s60.0 → 22.0; Yesterday had 7.93h VPD-high and dp-risk 0h.

Reduce VPD-high hours while dew margin stays above 5F.

fog_escalation_kpa0.45 → 0.15; Dry peak overlaps the 07-17 fog window.

Use the 7x fog path when misters lag in VENTILATE.

mister_water_budget_gal120.0 → 260.0; VPD is the bottleneck and water is below the practical cap.

Avoid clipping afternoon VPD recovery.

Reflection

Validating previous cycle: iris-20260624-0537

Previous hypothesis: SUNRISE plan 2026-06-24. I evaluated the active midnight plan iris-20260624-0020 at 5/10 while the deterministic anchor was 1. The +4 gap is deliberate but cautionary: biological safety was real in the pre-dawn window (68.3F, VPD 0.55 kPa, RH 77%, dew margin 7.6F, IDLE, no equipment running, dp-risk 0h), but the anchor correctly penalized 542 guardrail events, 231 held guardrail events, 16 dispatched guardrail events, and 247 VPD-high guardrail events. I am therefore treating realization proof, not just requested posture, as today’s success criterion. Yesterday’s full-day score was 66.5: temperature was excellent at 99.9% compliance, but VPD was the bottleneck at 66.2% with 7.93h VPD-high and only 0.03h heat; cost was USD 4.88 vs 7d USD 3.36, driven by water and electric, not gas… Result: Midnight evaluation of the 2026-06-24 SUNSET humid-night taper. Daily 2026-06-24 score finished at 77.6 with temp compliance 92.8%, VPD compliance 79.5%, VPD-high 4.77h, heat 1.67h, VPD-low/cold 0h, dp_margin_min 6.9F, dp-risk 0h, cost USD 2.29, water 75 gal and mister water 30 gal. The specific sunset-to-midnight window was safe and cheap (window cost about USD 0.156, no heat/cold/VPD-high/VPD-low stress), current live state is IDLE at 69.8F, VPD 0.49 kPa, RH 80%, dew margin 6.3F, with all climate relays off. The dew-safety and wet-suppression parts of the hypothesis were directionally met: no fog/mister overshoot and no condensation-risk hours. However the scoped scorecard reports 0% compliance / planner score 20 for the short window, the house_band_drift alert is open for too-wet/orchid-drying risk, and there are open setpoint_unconfirmed alerts plus multiple missed transition proofs. The Friday hot-dry fail-safe has not run. Score 4/10: biological safety succeeded, but target tracking and realization proof remain weak. Score: 4/10

Hypothesis

Testing: Humid-night taper after a VPD-high day: suppress wet assist overnight while dew margin is safe, then keep an offline Friday dry-ramp fail-safe. Expected outcome: Overnight dp-risk remains 0h, no VPD-low stress accrues from added moisture, water stays below the 7d trend, and tomorrow’s sunrise cycle can reopen moisture if live VPD rises.

vpd_lowmedium · 2026-06-24T23:00:00-06:00 to 2026-06-25T09:00:00-06:00

Suppress wet assist, keep dew margin floor high, and allow only safety/controller dehumidification rather than adding moisture.

vpd_highhigh · 2026-06-26T10:00:00-06:00 to 2026-06-26T19:00:00-06:00

Offline fail-safe reopens band-coupled mist/fog before Friday dry heat if sunrise cycles miss.

Parameter rationale

mister_engage_kpa1.1 → 1.25; Overnight RH 87-95%, VPD 0.09-0.23.

Avoid needless orchid wetting and hold dp-risk at 0h.

mister_all_kpa1.3 → 1.45; Humid night with west zone already wet.

Prevent all-zone wetting while VPD is below target.

mister_pulse_gap_s56.0 → 60.0; Humidity holds overnight and cost can be optimized.

Cut water/churn without worsening VPD-high.

fog_escalation_kpa0.4 → 0.5; Fog blocked overnight and dew safety is priority.

Avoid fog overshoot during humid recovery.

mister_water_budget_gal260.0 → 120.0; Thursday forecast is cool humid with low VPD.

Avoid water waste overnight, then future plan can reopen for Friday.
