Result: Plan-window score was 40.5 with only 35.7% both-axis compliance. Temperature compliance was 40.1% and VPD compliance 45.7%, so both axes failed but heat stress dominated slightly at 5.30h with 4.64h VPD-high and no cold/VPD-low. Daily scorecard at sunset is 47.6 with 42.0% both-axis compliance, temp 47.2% vs VPD 53.8%, 10.43h heat stress, 9.13h VPD-high, no VPD-low, dew margin safe at 7.6F min, but water hit the 600 gal mister budget and total cost rose to USD 4.51 vs USD 3.27 7d average. The severe hot-dry posture avoided dew/VPD-low carryover but did not achieve the expected VPD-high under 3h or score 55-60; repeated guardrail clamps show the evening/midday plan was still requesting values too conservative for active VENTILATE dry stress at times.

Reflection

Validating previous cycle: iris-20260513-2007

Previous hypothesis: SUNSET overnight recovery plan for 2026-05-13. Today’s score improved versus the 7-day average but remained weak: score 59.5, both-axis compliance 55.0% versus 47.7% 7-day average, with temperature now the bottleneck at 57.1% versus 72.1% VPD compliance. Heat stress dominated at 7.77h, with VPD-high also material at 5.45h. Cost was acceptable at USD 3.37 versus USD 3.94 7-day average, driven mainly by water (USD 2.06) and gas (USD 0.80); water use rose to 425 gal total / 365 gal mister-only because severe dry support was needed. I evaluated iris-20260513-0547 at 5/10 versus anchor 4: band-coupled moisture support preserved VPD-low and cost, but physics-limited cooling dominated. Tonight has healthy dew margin (~11F) but very dry outdoor air, so the plan does not fully suppress moisture; it uses bounded, guardrail-safe recovery with short sealed windows, wider gaps than daytime, bias_cool +3 to avoid heater/vent chatter, and an early Thursday dry-ramp handoff before the forecast 86F / 8% RH / ~822 W/m2 day.

Result: Plan-window score was 40.5 with only 35.7% both-axis compliance. Temperature compliance was 40.1% and VPD compliance 45.7%, so both axes failed but heat stress dominated slightly at 5.30h with 4.64h VPD-high and no cold/VPD-low. Daily scorecard at sunset is 47.6 with 42.0% both-axis compliance, temp 47.2% vs VPD 53.8%, 10.43h heat stress, 9.13h VPD-high, no VPD-low, dew margin safe at 7.6F min, but water hit the 600 gal mister budget and total cost rose to USD 4.51 vs USD 3.27 7d average. The severe hot-dry posture avoided dew/VPD-low carryover but did not achieve the expected VPD-high under 3h or score 55-60; repeated guardrail clamps show the evening/midday plan was still requesting values too conservative for active VENTILATE dry stress at times. Score: 4/10

New finding: On repeated 85-87F, RH <15%, solar >850 W/m2 days, daytime conservative moisture unwind can happen too early: if VPD-high and VENTILATE remain active near sunset with healthy dew margin, keep band-coupled moisture support until observed VPD recovery, then unwind gradually overnight. → Added to Lessons Learned

Hypothesis

Testing: Time-gated severe dry-day posture: use guardrail-safe band-coupled moisture and fog only during confirmed dry solar stress, then unwind by 17:30-20:00 to prevent VPD-low/dew carryover. Expected outcome: Target score 55-60 despite structural heat limits; VPD-high under 3h, VPD-low under 3h, heat stress likely 4-6h, dew-point risk 0h, cost below USD 4.50 and mister water below the 500 gal budget.

Conditions (structured)

Outdoor peak

87.0°F

RH minimum

7.0%

Solar peak

823.0 W/m²

Cloud average

35.0%

Another severe hot-dry spring day. Forecast RH falls below 20% by 10:00, reaches 7-9% from 14:00-19:00, VPD peaks near 4.1 kPa, and solar has a late 15:00 peak near 823 W/m2. Forecast VPD has a +0.7 kPa high bias and solar a small positive bias, but current dew margin is safe at 8.5F and recent dispatcher clamps show conservative moisture settings are being overridden during near-edge stress.

Expected stress windows

vpd_highhigh · 2026-05-14T09:00:00-06:00 to 2026-05-14T19:30:00-06:00

band-coupled physical mist thresholds 0.88-0.95 engage and 1.05-1.10 all, 30-60s delays, 15-22s peak gaps, fog_escalation_kpa 0.20-0.25 in the 07:00-17:00 fog window, mister_vpd_weight 2.7-3.0

pre-cool with bias_cool -1 to -2 and d_cool_stage_2 2.0-2.5; keep mist_max_closed_vent_s at 180s and rely on THERMAL_RELIEF/VENTILATE rather than extending sealed heat traps

vpd_lowmedium · 2026-05-14T20:00:00-06:00 to 2026-05-15T07:00:00-06:00

evening unwind to engage 1.30-1.45, all 1.70-2.00, 50-55s gaps, fog escalation 0.85-0.90 while fog is time-window blocked, vpd_hysteresis 0.50, and bias_cool +3 to prevent heater-vent chatter

Parameter rationale

mister_engage_kpa1.05 → 0.88; Thu 10:00-17:00 RH 7-18%, VPD 2.9-4.1 kPa, and recent vpd_high_moisture_guardrail clamps pushed conservative values down near 0.87

keep physical S1 support available near the active VPD band and reduce VPD-high hours versus yesterday without waiting for dispatcher clamps

mister_all_kpa1.2 → 1.05; active vpd_high is about 0.83 kPa; guardrail recommends all-zone near max(1.0, vpd_high + 0.25) during near-edge VENTILATE stress

allow all-zone escalation during the confirmed severe dry peak while not overusing it at dawn/night

mister_engage_delay_s90.0 → 30.0; dry ramp starts quickly after 09:00 and RH drops below 20% by 10:00

avoid missed early VPD-high excursions during the morning ramp

mister_all_delay_s180.0 → 60.0; recent guardrail clamps capped long all-zone delays to 90s during active stress

bring all-zone assist within one minute during severe VPD stress while evening waypoints restore slower delivery

mister_pulse_gap_s55.0 → 15.0; lessons for RH <20% and solar >800 W/m2 recommend 15-25s gaps; today peaks at 823 W/m2 and 7% RH

speed evaporative VPD recovery during peak, then unwind to 50-55s to prevent overnight VPD-low

fog_escalation_kpa0.9 → 0.2; PR-A permits vent-fog assist at vpd_high_eff plus escalation; forecast 87F/7% RH makes fog the high-leverage VPD support before 17:00

use fog for stubborn VPD while ventilation handles heat, without extending sealed mist

bias_cool3.0 → -2.0; forecast high 87F with heat window 11:00-18:30 and late solar peak

vent/fan earlier for pre-cooling and reduce avoidable heat stress while restoring +3 overnight to prevent heater-to-vent chatter

d_cool_stage_23.0 → 2.0; cooling is physics-limited and fan2 should not wait far above the shifted cooling threshold at peak

bring full ventilation support earlier during the hot dry peak

vpd_watch_dwell_s75.0 → 30.0; VPD forecast rises from 2.53 at 09:00 to above 3.5 by noon; conservative dwell is already being guardrail-clamped in live stress

enter recovery sooner during the fast ramp without disabling dwell gate

mist_backoff_s900.0 → 600.0; short 180s sealed attempts may time out under 85-87F heat; recovery should recur but stay bounded

allow repeated bounded recovery cycles without extending any individual heat trap

mister_vpd_weight1.8 → 3.0; south/west mister paths are most productive under high solar; crop observations show south/center stress, but zone VPD spread is currently modest

spend water on productive dry-zone recovery during the peak while returning to 2.0 overnight

vpd_hysteresis0.5 → 0.35; fast dry ramp needs fewer missed high-VPD entries; evening restores 0.50 to avoid VPD-low carryover

improve peak VPD responsiveness without narrowing the overnight band

Daily Summary So Far — this cycle will be validated at the next planning cycle.

Hypothesis

Testing: Observe whether delaying the full overnight unwind until VPD actually recovers reduces sunset VPD-high without causing VPD-low/dew risk, then hand off early enough for Friday’s severe dry ramp. Expected outcome: Overnight: dp_risk_hours 0, VPD-low under 1h, no cold stress, and cost flat because no gas is expected. Friday before sunset: VPD-high lower than today despite severe forecast, heat remains partly physics-limited, mister water may again approach budget but should translate into better VPD compliance.

Conditions (structured)

Outdoor peak

86.0°F

RH minimum

7.0%

Solar peak

915.0 W/m²

Cloud average

42.0%

Sunset follows a severe dry day with active VPD-high alert acknowledged. Current indoor VPD is still above the night high band but dew margin is safe near 15F. Overnight outdoor air is dry but cooling from the 70s to low 50s; Friday repeats severe hot-dry stress with RH 7-10% and solar near 900 W/m2. Forecast VPD has a known positive bias, so the aggressive posture is delayed until the live morning dry ramp.

Expected stress windows

vpd_highmedium · 2026-05-14T20:15:00-06:00 to 2026-05-14T23:00:00-06:00

keep moisture band-coupled while VPD is still above band: engage 0.95, all 1.10, 45/90s delays, 30s gap, fog_escalation 0.25 although fog is time-window blocked

vpd_lowlow · 2026-05-14T23:00:00-06:00 to 2026-05-15T06:30:00-06:00

after expected recovery, widen to engage 1.35-1.40, all 1.75-1.85, 50-55s gaps, fog_escalation 0.85-0.90, vpd_hysteresis 0.50, and short 180s sealed cap

vpd_highhigh · 2026-05-15T08:30:00-06:00 to 2026-05-15T19:30:00-06:00

morning handoff before severe dry ramp: engage 0.90, all 1.08, 30/60s delays, 20s gap, fog_escalation 0.20 in fog window, vpd_watch 30s, mister_vpd_weight 3.0

heathigh · 2026-05-15T12:00:00-06:00 to 2026-05-15T18:30:00-06:00

bias_cool -1.5 and d_cool_stage_2 2.0 for pre-cooling/full fan support, but keep mist_max_closed_vent_s 180s per lessons 95/89 rather than extending sealed heat traps

Parameter rationale

mister_engage_kpa1.3 → 0.95; live VPD 0.96 remains above active vpd_high 0.82 with 14.8F dew margin and recent guardrail clamps at 20:03

recover current VPD-high before unwinding; avoid another conservative setting that dispatcher must clamp

mister_all_kpa1.7 → 1.1; active VPD remains above band during VENTILATE and guardrail recommends all near vpd_high+0.25

allow all-zone assist during evening recovery, then widen after observed cooling

mister_pulse_gap_s15.0 → 30.0; night air holds humidity better than peak solar, but current VPD is still high

reduce water intensity versus daytime while not abandoning recovery

fog_escalation_kpa0.85 → 0.25; current VPD-high is unrecovered; fog is blocked after 17:00 but this prevents stale conservative posture if guardrail/firmware window interactions occur

keep evening posture aligned with stress until recovery, then raise to 0.85-0.90 overnight

bias_cool3.0 → 2.5; current mode is VENTILATE at 68F, with overnight cooling but not a <45F cold night

reduce avoidable venting gradually without locking in heat; late-night +3.5/+4 prevents heater-to-vent chatter

vpd_watch_dwell_s75.0 → 45.0; live VPD-high remains active at sunset and outdoor air remains very dry through 23:00

enter bounded recovery sooner during evening, then lengthen overnight to avoid short-cycling

mister_vpd_weight2.0 → 2.3; north/east remain driest and Vanda roots show dryness, but overnight should not use full peak-day water intensity

moderate targeted recovery without the full 3.0 daytime water spend

mist_max_closed_vent_s180.0 → 180.0; validated lessons 95/89 and today's heat stress show sealed heat traps should not be extended

protect dew/heat safety while accepting structural heat limits

d_cool_stage_23.0 → 2.0; Friday forecast reaches 86F with RH 7% and solar near 915 W/m2

bring fan2 earlier during tomorrow's physics-limited heat window
