Live solar is high at 1068 W/m2 and above bias-corrected forecast, but the active SUNRISE plan already covers the dry afternoon with guardrail-aware band-coupled moisture: fog_escalation_kpa 0.20, mister_engage_kpa 1.20 now moving to 1.10 at 14:30, mister_all_kpa 1.45 now moving to 1.30, short delays/gaps, and healthy dew margin 14.4F.

Peak Stress14:58TRANSITIONackedAcknowledged: Peak-stress transition checked. Current house is in VENTILATE with vent and both fans active; avg VPD 1.25 is only slightly above active vpd_high 1.23, east 1.37 while south/west are below/near targets, dew margin is safe at 13.1F, and the active SUNRISE plan is already in guardrail-aware peak-dry posture (mister_engage_kpa 1.05, mister_all_kpa 1.25, gap 25s, fog_escalation_kpa 0.20).

East remains locally dry at 1.10 kPa and recent guardrail evidence shows VPD-high is not fully recovered, so an early unwind would risk cutting support before recovery. Existing plan already carries the dry-evening posture until 22:30, then unwinds to conservative overnight thresholds; no concrete signal warrants a one-shot tunable change. Resolved 19:17 MDT.

No heat, VPD, dew-risk, or equipment signal warrants a tunable change; treating this as a wind forecast error rather than a regime shift. Resolved 20:58 MDT.

Validating previous cycle: iris-20260521-0541

Previous hypothesis: SUNRISE plan for Thursday 2026-05-21. Yesterday scored 71.9 with 76.9% both-axis compliance; VPD-low was the largest stress at 2.53h, while temp compliance was only slightly better than VPD compliance. The just-evaluated sunset plan scored 8/10, matching anchor 8: the cold saturated overnight posture avoided VPD stress and dew risk, with remaining loss mostly structural temperature-band alignment. Today starts cold and saturated around 41F/96% RH, indoor VPD 0.46 and dew margin 7.4F, but the forecast turns into a high-solar dry afternoon: 64-72F, RH 24-34%, raw VPD 1.5-2.0 kPa, solar 800+ W/m2 around midday. The plan keeps dawn moisture suppressed, then moves earlier than yesterday into guardrail-aware band-coupled moisture so the dispatcher does not need to clamp conservative values during VPD-high VENTILATE. Evening unwinds before RH rebounds. Result: Window scorecard while this midnight reset governed: cost about USD 0.226, both-axis compliance 64.4%, temp compliance 74.6%, VPD compliance 77.4%, heat stress 0.90h, cold stress 0.23h, VPD-high 0.79h, VPD-low 0.22h, total stress 1.30h, planner score 63.9. The plan correctly protected the cold saturated pre-dawn period with low VPD-low and dew-risk at 0h, then handed off to daytime dry-ramp support; remaining misses were mostly heat/VPD pressure and crop-band narrowness rather than condensation or over-misting. Score: 6/10

New finding: Cold saturated midnight/pre-dawn resets can safely use high moisture thresholds, conservative fog, short sealed residence, dwell gate ON, bias_cool +4, and modest heat support; expect some structural temp-band loss, but VPD-low and dew risk should stay low. → Added to Lessons Learned

Hypothesis

Testing: Test a two-stage Friday handoff: guarded humid/cold morning, then guardrail-aligned peak moisture instead of values the dispatcher must clamp. Expected outcome: Friday target: dp_risk_hours 0, VPD-low under 1h, VPD-high under 1.5h, cold stress near or below 1h, and fewer VPD-high moisture guardrail events than the evaluated SUNRISE plan.

vpd_lowmedium · 2026-05-22T00:20:00-06:00 to 2026-05-22T10:30:00-06:00

vpd_highmedium · 2026-05-22T13:00:00-06:00 to 2026-05-22T19:30:00-06:00

Guardrail-aware moisture: engage 1.10-1.30, all 1.30-1.60, 45/90s peak delays, 25-35s gaps, fog_escalation 0.25-0.45, min_fog_off 60-90, bounded 150-180s sealed cap.

vpd_lowmedium · 2026-05-22T20:30:00-06:00 to 2026-05-23T07:00:00-06:00

Evening unwind to engage 2.35, all 2.5, 60s gaps, fog_escalation 1.0, long delays, short sealed residence before RH rebounds.

Parameter rationale

mister_engage_kpa2.35 → 2.45; 00:20-08:30 cold saturated air, current VPD 0.35 and dew margin 5.7F.

Avoid pre-dawn mist/fog and keep dp-risk at 0h while VPD-low stays bounded.

bias_heat1.5 → 2.0; Outdoor 42-48F pre-dawn with heat1 and heat2 already active.

Limit cold score loss without raising crop bands or continuous overheating.

mister_engage_kpa2.2 → 1.1; 13:00-16:00 dry solar ramp, RH 23-38%, VPD 1.1-1.8 kPa, and prior plan anchor penalty from guardrail events.

Reduce VPD-high to under 1.5h and avoid repeated dispatcher moisture guardrail rewrites.

mister_all_kpa2.5 → 1.3; Recent guardrail clamps pushed all-zone escalation toward 1.3 during live VPD-high stress.

Allow all-zone assist during the dry peak instead of waiting far above the active band.

fog_escalation_kpa1.0 → 0.25; Fog is blocked/unneeded overnight but useful after 13:00 if VPD remains high with healthy dew margin.

Catch stubborn VPD-high during VENTILATE assist without overnight fog or condensation risk.

mister_pulse_gap_s60.0 → 25.0; Afternoon RH in the low 20s to low 30s needs faster evaporation support; saturated dawn needs 55-60s gaps.

Improve VPD recovery in the dry window while evening unwind prevents carryover.

bias_cool4.0 → 2.0; Midday solar and dry air create heat/VPD pressure; cooling should not be delayed as much as overnight.

Reduce heat-stress risk while retaining enough hysteresis to avoid chatter.

Previous hypothesis: SUNSET overnight plan for Thursday 2026-05-21. Today improved versus the 7-day trend but still missed target: score 71.9, both-axis compliance 74.8% versus 70.7% 7-day, temp 83.1%, VPD 85.4%, total stress 6.37h. Heat stress was the largest single stress at 2.55h, followed by VPD-high 2.10h; VPD-low and cold were contained at 0.85h and 0.87h. Cost was USD 5.92, better than the 7-day USD 7.39 average, driven mostly by electric/grow-light/fog modeled cost and gas heat; water and misting were far below the 7-day average. The evaluated midnight plan scored 7/10, matching anchor 7. Current house is IDLE at about 66.5F, VPD 0.66 kPa, RH 70%, with safe 9.9F dew margin. Tonight turns cold and saturated outside, 51F falling to 41F with outdoor VPD 0.07-0… Result: SUNRISE-to-sunset window scorecard: both-axis compliance 70.3%, temp compliance 78.2%, VPD compliance 83.5%, total stress 3.86h with heat 2.26h, cold 0.58h, VPD-high 1.89h, VPD-low 0.50h, cost about USD 0.61. The free-text goal partly worked: Friday moisture support kept VPD-high below the daily 3.7h total and dew safety held at dp-risk 0h. But the structured hypothesis expected guardrail-aware band-coupled support to avoid dispatcher rewrites; actual plan/audit evidence showed 55 VPD-high moisture-guardrail events including held and dispatched interventions. Actual weather was cooler and much more humid than the severe forecast proxy, but solar exceeded forecast. Grade aligned low because execution quality still fought the dispatcher/firmware moisture policy despite acceptable window scorecard. Score: 2/10

New finding: On cool saturated dawns followed by solar near or above 900 W/m2 and RH near or below 20%, guardrail-aware moisture must be fully band-coupled during live VPD-high VENTILATE: engage near vpd_high+0.05, all-zone near max(1.0,vpd_high+0.25), fog_escalation 0.15-0.20, short delays, and delay evening unwind until observed VPD recovery rather than clock time alone. → Added to Lessons Learned

Hypothesis

Testing: Live-confirmed dry-ramp handoff: keep dawn conservative, then use guardrail-aligned band-coupled moisture from the first observed/forecast dry ramp through the late dry evening instead of unwinding at sunset by clock alone. Expected outcome: Target Friday score >78 with both-axis compliance >82%, VPD-high stress <1.5h, VPD-low stress <0.5h, dp-risk 0h, and cost below the 7-day average; if Saturday fallback is reached, keep severe-ramp VPD-high materially lower than a conservative posture without extending sealed heat traps.

Friday starts cold/saturated near 41F/85% RH with indoor VPD 0.56 and 8.6F dew margin, then dries to RH 21-28%, VPD 1.5-1.8 kPa, and solar near 817 W/m2. Saturday fallback is more severe: RH near 9%, VPD near 3.0 kPa, solar around 900 W/m2. Forecast solar has recently overestimated reality, so the plan waits through dawn but uses band-coupled values once the dry ramp is plausible.

Expected stress windows

vpd_lowlow · 2026-05-22T05:45:00-06:00 to 2026-05-22T10:30:00-06:00

Keep mist/fog suppressed while indoor VPD is 0.56 and outside remains cold/high-RH: engage 2.35 then 1.75, long-ish delays, 45-60s gaps, fog_escalation 0.8-1.0, short sealed cap.

vpd_highmedium · 2026-05-22T12:30:00-06:00 to 2026-05-22T21:30:00-06:00

Use guardrail-aware band-coupled moisture: engage 1.05-1.20, all 1.25-1.45, 30-45s engage delays, 60-90s all delays, 25-30s gaps, fog_escalation 0.20-0.35 while the fog window allows it, and 150-180s sealed cap.

vpd_lowmedium · 2026-05-22T22:30:00-06:00 to 2026-05-23T08:30:00-06:00

After RH rebounds, unwind to engage 2.35, all 2.5, 60s gaps, fog_escalation 1.0, long delays, bias_cool +4, modest bias_heat, and 120s sealed cap.

vpd_highhigh · 2026-05-23T11:30:00-06:00 to 2026-05-23T20:00:00-06:00

Missed-cycle fallback for severe Saturday: engage 1.00, all 1.20-1.25, 30/60s delays, 20s gaps, fog_escalation 0.15, min_fog_off 45, 180s sealed cap, and 600s backoff so VENTILATE/THERMAL_RELIEF are not fought.

Parameter rationale

mister_engage_kpa2.45 → 1.05; Friday 14:00-20:00 RH 21-33%, VPD 1.32-1.76 kPa, solar up to 817 W/m2; recent clamps pushed conservative requests down near 1.06.

Avoid dispatcher rewrites and keep Friday VPD-high under about 1.5h while not misting the cold saturated dawn.

mister_all_kpa2.5 → 1.25; Recent vpd_high_moisture_guardrail clamped all-zone threshold toward about 1.32 during live dry ventilation.

Permit all-zone support during dry VENTILATE assist instead of waiting far above the active VPD band.

fog_escalation_kpa1.0 → 0.2; Friday dry window overlaps the 07:00-17:00 fog window through the peak, and fog is 7x more effective than misters when VPD remains stubborn.

Catch stubborn VPD-high without using fog during dawn or after the firmware fog window.

mister_pulse_gap_s60.0 → 25.0; Afternoon RH falls below 30% with VPD above 1.5 kPa; lesson 104 and guardrail audit favor faster evaporation support once the ramp appears.

Improve VPD recovery during dry ventilation while later unwind prevents VPD-low carryover.

mister_engage_delay_s300.0 → 30.0; Long delays were repeatedly shortened by the moisture guardrail during VPD-high stress.

Start physical pulses promptly once humidity demand exists in dry ventilation.

mister_all_delay_s600.0 → 60.0; Dry afternoon VPD can climb quickly after 13:00; all-zone escalation should not wait 5-10 minutes once above band.

Reduce time above the VPD band and avoid held guardrail events.

min_fog_off_s180.0 → 60.0; Guardrail audit shortened fog-off dwell during live VPD-high; Friday has healthy dew margin and low outdoor RH at peak.

Allow effective fog cadence while firmware RH/temp/time gates protect condensation.

bias_heat2.0 → 0.0; Outdoor warms into the 60s by afternoon; heat support should taper with solar and avoid heat/vent churn.

Limit morning cold-band loss without adding gas/electric heat through the dry peak.

bias_cool4.0 → 2.0; Dawn heaters justify +4 anti-whipsaw, but dry solar pressure needs earlier ventilation after midday.

Reduce heat-stress accumulation while keeping overnight heater-to-vent oscillation suppressed.

mist_max_closed_vent_s120.0 → 180.0; Dry peak needs bounded sealed recovery, but temperatures are not extreme Friday and THERMAL_RELIEF preempts after the cap.

Improve VPD-high recovery without creating a thermal trap.

Reflection

Validating previous cycle: iris-20260522-0540

Previous hypothesis: SUNRISE plan for Friday 2026-05-22. Yesterday improved to 73.8 but still missed target: both-axis compliance 77.6%, temp 84.6%, VPD 87.6%, with heat stress 2.72h and VPD-high 2.10h as the main misses. The evaluated sunset plan scored 8/10 versus anchor 6: it protected VPD and dew safety overnight, but the anchor penalized 14 guardrail events, so today’s plan must stop fighting the moisture guardrail during dry ventilation. Current house is IDLE with heat1 on, 65.4F, VPD 0.56, RH 74%, dew margin 8.6F, and outdoor air is cold/saturated. Forecast shifts to a dry afternoon: Friday outdoor RH falls to 21-28%, VPD 1.5-1.8 kPa, solar peaks near 817 W/m2; Saturday fallback is severe with RH near 9%, VPD near 3.0 kPa, and solar near 900 W/m2… Result: Revised after anchor comparison. Although the live climate at 00:20 looked safe (IDLE, 64.9F, VPD 0.37 kPa, dew margin 5.6F) and stress counters were still near zero, the deterministic evaluation exposed a major execution-quality failure: anchor_score 1 with 14 VPD-high moisture-guardrail dispatches during the plan window plus incomplete Tier-1 coverage in future waypoints. The plan also carried partially conservative moisture values that the dispatcher had to rewrite, repeating the same guardrail-fighting pattern identified in the evaluated SUNRISE plan. The midnight boundary scorecard row was sparse, but anchor/guardrail evidence is stronger than my initial live-state impression. Final grade aligned to anchor: 1/10. The actionable miss is not plant safety at midnight; it is that the written plan still failed the policy contract and should be replaced with complete Tier-1 waypoints and fully band-coupled peak dry-day moisture support. Score: 1/10

New finding: When a SUNSET or MIDNIGHT plan includes a severe next-day dry fallback, incomplete Tier-1 coverage or partially conservative moisture values can trigger VPD-high guardrail dispatches even before the main dry window; anchor/guardrail evidence should override a superficially safe live midnight snapshot. → Added to Lessons Learned

Hypothesis

Testing: Overnight saturated-air suppression with a guardrail-aligned severe-dry missed-SUNRISE fallback: do not repeat today’s partially conservative moisture values that triggered 55 guardrail events. Expected outcome: Overnight through 08:30: dp_risk_hours 0, VPD-low under 0.5h, cold stress near or below 1h, and cost dominated by efficient gas/electric heat rather than water/fog. If SUNRISE is missed, late-morning fallback should avoid VPD-high guardrail holds by using fully band-coupled moisture.

Missed-SUNRISE fallback uses fully guardrail-aligned band-coupled support: engage 1.00, all 1.20, 30/60s delays, 20s gaps, fog_escalation 0.15, min_fog_off 45, 180s sealed cap, and 600s backoff.

Parameter rationale

bias_cool3.0 → 4.0; Heaters are already active and outdoor falls to 43F with saturated air by dawn; validated overnight lessons favor +3 to +4 to prevent heater-to-vent dumps.

Keep overnight cold stress near or below 1h without vent-chatter-driven temperature loss.

bias_heat0.0 → 2.0; Pre-dawn forecast reaches 43F with RH about 90%; gas heat is efficient and slab alone may sit near the lower crop band.

Limit pre-dawn cold-band scoring while avoiding continuous overheating or crop-band changes.

mister_engage_kpa1.2 → 2.45; 22:00-08:30 outdoor VPD collapses to 0.08-0.21 kPa and current indoor RH is already 71% with safe dew margin.

Avoid added overnight moisture, keep dp-risk at 0h, and prevent VPD-low accumulation.

mister_all_kpa1.45 → 2.5; All-zone escalation is unnecessary during saturated overnight air and would risk VPD-low carryover.

Keep overnight mister water near zero unless live VPD breaks well above band.

mister_pulse_gap_s30.0 → 60.0; Nighttime sealed air holds moisture; lesson 105 says unwind after dry-day support with wider gaps and higher thresholds.

Reduce VPD-low and condensation risk while maintaining dew margin above 5F.

fog_escalation_kpa0.35 → 1.0; Fog is time-window blocked overnight and unnecessary in saturated air.

Avoid fog-driven VPD-low; keep dp-risk at 0h.

mist_max_closed_vent_s150.0 → 120.0; Dew margin is safe now, but outdoor RH reaches about 90%; any accidental sealed-mist state should stay short.

Preserve condensation safety if the controller briefly enters humidification.

mister_engage_kpa2.45 → 1.0; Saturday missed-SUNRISE fallback: 11:00-20:00 RH 9-21%, VPD 1.99-2.89 kPa, solar near 900-1000 W/m2; the just-evaluated plan was penalized for 55 guardrail events.

Avoid fighting the VPD-high moisture guardrail and keep severe-day support band-coupled if the morning plan is missed.

fog_escalation_kpa1.0 → 0.15; Saturday dry window overlaps fog window and severe VPD-high ventilation; fog is 7x more effective than misters and guardrail wants 0.15-0.20 in hot/dry venting.

Catch stubborn VPD-high during VENTILATE assist without extending sealed heat traps.
