Solar peak planning checkpoint13:06SOLAR_MAXackedAcknowledged: SOLAR_MAX no-change: live solar is high (~1031 W/m2, above the 14:00 forecast 914 W/m2), but indoor climate is still inside controller bands (81.1F vs temp_high 83.8F; VPD 1.07 kPa vs vpd_high 1.22 kPa; dew margin 10.4F; IDLE). Existing SUNRISE plan already has compliance-first hot-dry posture active/queued: fog_escalation_kpa 0.15, mister_pulse_gap_s 16s, engage 0.95, all-zone 1.10, water budget 300 gal, direct wet stress override enabled, all fans at high enabled... Resolved 13:07 MDT.
Peak Stress15:02TRANSITIONackedAcknowledged: Peak-stress transition checked live climate/equipment/active plan/setpoints. Conditions are tracking the existing hot-dry posture: temp 82.1F is below temp_high 85.1F, VPD 1.21 kPa is only 0.01 above vpd_high with dew margin 10.6F, and the controller is in SEALED_MIST_FOG recovery. Current wet/fog tunables are already compliance-first and near/at the aggressive hot-dry floor (mister_engage 0.95, mister_all 1.10, pulse gap 16s, fog_escalation 0... Resolved 15:03 MDT.
Decline19:34TRANSITIONackedAcknowledged: Decline transition checked: current greenhouse is IDLE and safe at 78.6F, house VPD 0.90 kPa within the active band, RH 74%, dew margin 9.1F, with vent/fans/fog/heaters off. Existing plan already schedules the evening unwind at 21:30 (wider mist gap and fog escalation back to 0.4), while current east-zone dry outlier means an immediate aggressive unwind could prematurely suppress recovery. No tunable change needed. Resolved 19:35 MDT.
Forecast deviation19:57FORECAST_DEVIATIONackedAcknowledged: FORECAST_DEVIATION assessed as cloud-cover forecast error/weather nowcasting variance after sunset, not a live control miss. Current climate is safe: 80.0F, VPD 0.99 kPa near vpd_high 0.98, RH 72%, dew margin 9.7F, mode IDLE. Equipment state shows no cooling/heating/fog running; only west mister reported on briefly while wet-assist posture is already enabled. Higher clouds reduce solar/heat load rather than requiring added cooling or moisture tuning. No setpoint change needed. Resolved 19:57 MDT.

Reflection

Validating previous cycle: iris-20260617-0533

Previous hypothesis: SUNRISE plan for Wednesday 2026-06-17. I evaluated the active early replacement plan iris-20260617-0105 at 5/10; the deterministic anchor was 1, and the gap is intentional but important: I gave limited credit for good temperature/dew safety and no heat/cold/VPD-low stress in the short pre-sunrise segment, while the anchor correctly penalized 261 guardrail events, 9 held guardrail events, and realization risk. Yesterday 2026-06-16 scored 64.1 with 60.4% compliance; VPD was the bottleneck at 61.1% vs 91.7% temp compliance, and stress was dominated by 9.15h VPD-high plus 1.95h heat. Cost was USD 3.18, below the 7d average USD 4.60, driven mostly by electric cooling/fog USD 2.22 and water USD 0.89 rather than gas USD 0.07; water use 183 gal was below the 7d average 497 gal, so under-spending was not climate success while VPD remained high. Current state is safe but about to ramp: 70… Result: Evaluated at SUNRISE replacement after the completed midnight-to-dawn segment. Partial/day score is 40.1 with 30.7% compliance, 100.0% temp compliance, 30.7% VPD compliance, 3.8h VPD-high stress so far, no heat/cold/VPD-low stress, dp margin min 10.0F and no dp-risk hours. Yesterday’s full day (2026-06-17) scored 48.9 with 41.3% compliance, temp 92.6%, VPD 42.1%, 15.33h stress dominated by 13.6h VPD-high plus 1.73h heat, cost USD 3.14 below 7d USD 4.68, water 343 gal below 7d 506 gal. The midnight plan preserved temperature/dew safety but did not resolve the main dry-axis bottleneck; the hot-dry window has not yet occurred, and realization alerts remain open for several moisture/fog setpoints. Score is 4/10 because safety and temperature were good, but VPD compliance is already poor and setpoint confirmation is still the realization risk. Score: 4/10

Hypothesis

Testing: Hot-dry realization recovery: keep bounded wet/fog intent open through Thu/Fri peaks and judge by VPD compliance, hot-dry vent-mist utilization, setpoint confirmation, and dp safety, not by low cost alone. Expected outcome: For Thu 2026-06-18 target >50% VPD compliance, >85% temp compliance, VPD-high stress below Wednesday’s 13.6h full-day value, dp-risk 0h, no VPD-low carryover, and fewer vent_vpd_moisture_gap/setpoint_unconfirmed repeats.

Validating previous cycle: iris-20260617-0533

Result: SUNSET evaluation for Thu 2026-06-18: window score 46.7 with 39.1% compliance, temp compliance 81.8%, VPD compliance 39.1%, stress dominated by 5.45h VPD-high plus 0.11h heat, no cold or VPD-low stress. Full-day score 52.3, temp compliance 98.9%, VPD compliance 47.3%, total stress 10.79h almost entirely VPD-high. Cost USD 4.12 vs 7d USD 3.79, driven mostly by electric cooling/fog USD 2.57 and water USD 1.22, with gas USD 0.33. Dew safety held: dp margin min 8.1F, dp-risk 0h. The plan preserved safety and temperature overall and VENT_COOL_FOG_ASSIST/VENT_COOL_MIST_ASSIST improved VPD error in response priors, but the primary VPD-compliance goal failed; setpoint realization and band-device divergence remained key risks, and zone spread remained large. Score: 4/10

New finding: On 85-90F clear dry days, vent-mist/fog assist can improve immediate VPD error while still failing daily VPD compliance if realization drift and zone spread persist; keep evening recovery wet-assist available only while VPD is still above band and dew margin is safe, but carry forward realization proof and zone-spread diagnostics as first-class success criteria. → Added to Lessons Learned

Hypothesis

Testing: Hot-dry realization proof: keep bounded wet/fog ClimateIntent open through the Thu/Fri/Sat dry peaks and judge success by VPD compliance, vent-mist/fog utilization, setpoint confirmation, and dew safety, not by low cost/water. Expected outcome: For 2026-06-18, keep temp compliance above 90%, improve VPD compliance above yesterday’s 42.1% if setpoints confirm, keep dp-risk at 0h and cost below about USD 5 despite higher mist/fog use.

Clear hot-dry Thursday after safe but dry-biased midnight segment. Forecast VPD has known positive bias (~1.2 kPa), but corrected afternoon VPD remains well above band. Current state: 65.2F, VPD 0.66 kPa, RH 69%, dew margin 10.4F, IDLE/heat1.

Keep wet assist band-coupled: mister_engage near vpd_high+0.05, mister_all near vpd_high+0.20, mist duty 55-60%, fog escalation 0.15 during firmware-safe fog window, wet cutoff through 21:00, low resource sensitivity until actual VPD recovery.

Repeat compliance-first moisture/fog posture on another 89F, low-RH, high-solar day and delay taper until observed VPD recovery.

vpd_highhigh · 2026-06-20T09:00:00-06:00 to 2026-06-20T21:00:00-06:00

Saturday may reach upper 90s with very low RH; hold maximum safe wet/fog availability and treat heat as physically constrained by ventilation capacity.

Parameter rationale

mister_engage_kpa0.82 → 0.95; Clear dry ramp from 09:00 with raw VPD 1.58 rising to 3.8 kPa and corrected VPD still above band; dew margin is currently 10.4F.

Keep first-stage wet assist eligible near the dispatcher VPD-high edge whenever safety gates are healthy.

mister_all_kpa1.01 → 1.1; Yesterday VPD-high dominated and the current 3h max VPD spread reached 0.69 kPa; whole-house dry pressure is forecast by midday.

Escalate all-zone mist early enough during the dry ramp and reduce localized dry outliers versus the prior day.

fog_escalation_kpa0.22 → 0.15; Heat/VPD overlap the 07:00-17:00 fog window and high-confidence lessons say fog is the 7x path for hot-dry VENTILATE when dew margin is safe.

Improve VPD recovery during hot-dry VENTILATE if setpoint confirmation and fog gating realize correctly.

mister_pulse_gap_s22.0 → 20.0; Yesterday cost and water were below 7d averages while VPD compliance remained only 42.1%, so resource clipping is the wrong daytime lever.

Prevent water/electric optimization from spacing pulses too far apart during safe VPD-high recovery.

mister_water_budget_gal280.0 → 300.0; VPD-high persisted 13.6h yesterday while water remained below 7d average; budget should not bind during safe dry stress.

Keep water budget from limiting stress recovery during the peak window.

dwell_gate_ms210000.0 → 210000.0; Dwell gate is enabled and THERMAL_RELIEF preempts it; keep churn discipline while monitoring missed/unconfirmed setpoints.

Avoid adding vent/heat whipsaw while preserving safety preemption and active VPD response.

Reflection

Validating previous cycle: iris-20260618-0536

Previous hypothesis: SUNRISE plan for Thursday 2026-06-18. I evaluated iris-20260618-0017 at 4/10; deterministic anchor was 1, and the gap is intentional but significant: I gave limited credit for preserved temperature/dew safety in the short midnight-to-dawn segment, while the anchor correctly penalized heavy guardrail activity (731 guardrail events, 94 held, 104 VPD-high guardrail events) and continuing setpoint realization risk. Yesterday 2026-06-17 scored 48.9 with 41.3% compliance, temp 92.6%, VPD 42.1%, 15.33h stress dominated by 13.6h VPD-high plus 1.73h heat. Cost was acceptable at USD 3.14 vs 7d USD 4.68, water 343 gal vs 7d 506 gal, and dew margin stayed safe at 7.1F min with 0 dp-risk hours; low cost/water was not success because VPD remained the bottleneck. Current greenhouse is safe at 65.2F, VPD 0.66 kPa, RH 69%, dew margin 10… Result: Midnight evaluation of the completed sunset-to-midnight segment: window score 34.9, compliance 20.0%, temp compliance 100.0%, VPD compliance 20.0%, vpd_high stress only 0.04h, no heat/cold/VPD-low stress, low cost around USD 0.13 and dew safety preserved with no dp-risk. The hypothesis partly held: the overnight taper avoided VPD-low and condensation and did not add material VPD-high stress after 22:00, but it left the house dry-edged at 69.0F, VPD 0.96 kPa with east 1.12 kPa and current VPD above the band, so the posture is not sufficient as a handoff into Friday’s hot-dry ramp. Full 09:00 ramp readiness cannot be graded yet because the plan ended at midnight. Score: 5/10

New finding: A short overnight taper after a hot-dry day can preserve dew safety and avoid VPD-low, but if VPD remains above the band by midnight the next plan should reopen band-coupled wet assist before dawn rather than conserving water into a hot-dry ramp. → Added to Lessons Learned

Hypothesis

Testing: Overnight taper test: keep bounded evening recovery until VPD is safely below high band, then trade peak daytime moisture aggression for stable low-duty overnight posture; judge by no VPD-low/dp-risk and readiness for Friday ramp. Expected outcome: By Friday 08:30, dew-point risk remains 0h, VPD-low remains 0h, overnight VPD-high does not grow materially after 22:00, and relay churn falls versus today’s high transition counts while wet/fog assist is re-opened for the 09:00 dry ramp.

Sunset state safe but dry-edged: indoor 79.7F, VPD 0.93 kPa near high band, RH 74%, dew margin 9.2F, IDLE. Overnight is mild/dry with forecast VPD biased high; Friday ramps hot/dry again after 09:00. Context degraded: knowledge/lesson semantic retrieval missing OPENAI_API_KEY, static site context missing, validate-plan-coverage unavailable.

Expected stress windows

vpd_highmedium · 2026-06-18T20:45:00-06:00 to 2026-06-18T22:00:00-06:00

Keep bounded evening recovery wet assist available while dew margin is >8F and VPD remains near high band; taper after recovery rather than by clock alone.

vpd_lowlow · 2026-06-19T00:00:00-06:00 to 2026-06-19T06:30:00-06:00

Reduce overnight wet duty and increase resource/churn discipline so cooling air and slab retention do not over-humidify the orchid zone.

vpd_highhigh · 2026-06-19T09:00:00-06:00 to 2026-06-19T21:00:00-06:00

Friday ramp returns to band-coupled moisture/fog posture with low resource sensitivity, mist duty 35-45%, fog escalation near 0.20 during the safe fog window, and wet cutoff through 21:00 recovery.

Parameter rationale

mister_engage_kpa0.96 → 1.03; After sunset, current VPD is just under high band with safe 9.2F dew margin and forecast VPD is biased high while temperatures cool.

Keep only guarded evening recovery eligibility overnight, then return near band edge for Friday morning dry ramp.

mister_all_kpa1.15 → 1.25; Large zone spread persists, but overnight evaporative demand falls and west is already humid.

Avoid unnecessary all-zone wetting overnight while not disabling all-zone escalation if the east dry outlier remains above band.

mister_pulse_gap_s24.0 → 45.0; No solar overnight and dp-risk has been 0h; high water/fog transitions today justify stable low-duty overnight moisture.

Hold VPD near band with fewer water-flow transitions and no VPD-low overshoot.

fog_escalation_kpa0.25 → 0.4; Fog is blocked outside the 07:00-17:00 firmware window and not needed overnight; VPD is near-band, not severe live stress.

Prevent peak hot-dry fog posture from carrying into the cool sealed night while allowing re-escalation to 0.20 for Friday morning.

mister_water_budget_gal280.0 → 200.0; Overnight is not the active hot-dry stress window and today’s water spend did not resolve VPD compliance.

Conserve overnight water while preserving tomorrow daytime budget for true VPD-high stress.
