Validating previous cycle: iris-20260723-0552

Previous hypothesis: SUNRISE plan for Thursday 2026-07-23. Yesterday closed below baseline at planner score 59.6 versus a 67.7 seven-day average. Temperature and VPD were essentially tied as bottlenecks (48.1% temp, 48.0% VPD), with stress dominated by heat at 10.72h, then VPD-high at 7.09h and VPD-low at 2.99h. Water use was sharply below average (148 gal total / 19 gal mister vs 360 gal 7-day average), so conservation happened but corridor recovery did not. Dew safety held at dp_margin_min_f 7.0F and 0 dp-risk hours. I evaluated iris-20260722-2024 at 6/10, but the deterministic anchor was 3 because 399 VPD-high guardrail events and 367 held guardrail events show materialization still diverged from requested posture; I credit the scoped evening window’s safety and modest stress, while the anchor correctly penalizes guardrail-heavy action proof… Result: Evaluated at 2026-07-24 SUNRISE for the partial pre-dawn window before supersession. Window score was 76.3 with temp compliance 46.7% and VPD compliance 38.4%; scoped stress was low at about 0.66h, with no heat or cold stress in the early window and the main severe hot-dry stress windows still future-facing. Dew safety held but margin was narrowing: current dp margin about 5.9F and dp-risk remained 0h. The plan correctly avoided mist/fog while the house was too wet, but it did not clear low-side VPD/orchid-drying risk by sunrise, and several direct-wet-stress override fields showed missed materialization in the transition audit. The forecast still calls for a severe hot-dry ramp later today, so the wet-assist part of the hypothesis remains unproven and should be re-staged from live ramp confirmation rather than credited now. Score: 6/10

Hypothesis

Testing: Guardrail-compatible severe-day wet assist with live-ramp confirmation: suppress only the humid pre-dawn wetting, then open band-coupled mister/fog posture once VPD confirms the dry ramp, without chasing target lines inside the crop corridor. Expected outcome: By sunrise, 0 dp-risk hours and no material VPD-low accumulation; by Friday evening, VPD-high stress should be below recent 7-15h severe-day runs if wet assist materializes, while heat stress may remain high because 98-103F afternoons are physics-limited.

third severe dry day gets the same live-confirmed band-coupled wet/fog assist and evening recovery

Parameter rationale

mister_engage_kpa1.62 → 1.27; Friday 10:00-18:00 raw VPD rises from 1.75 to 4.96 kPa, with current vpd_high about 1.22 kPa and validated lessons recommending vpd_high+0.05 in hot-dry VENTILATE

make S1 moisture available near the high edge once live dry stress appears, reducing VPD-high severity without waiting for extreme excursions

mister_all_kpa1.77 → 1.47; whole-house severe dry stress is forecast for Friday through Sunday with modest zone spread, so all-zone escalation should be close to vpd_high+0.20 to +0.25

allow all-zone rotation during broad dry stress while avoiding unnecessary pre-dawn wetting

fog_escalation_kpa0.5 → 0.15; fog is the 7x moisture path and the severe dry/heat windows overlap the 07:00-17:00 fog allowance with dew margin currently safe

lower VPD-high severity during hot-dry VENTILATE when firmware dew/RH/time gates permit fog

mister_water_budget_gal100.0 → 300.0; recent low-water days did not recover corridor compliance and the next three afternoons are severe hot-dry events

avoid budget-limited VPD recovery during safe severe dry stress while still using the pre-dawn wet restraint window

mister_pulse_gap_s60.0 → 22.0; validated lessons for dry RH below 20% call for 15-25s gap, and recent guardrails repeatedly held long gaps down during VPD-high stress

keep wet duty effective and guardrail-compatible during confirmed dry stress, then let evening/dew posture taper after recovery

Validating previous cycle: iris-20260723-2024

Previous hypothesis: SUNSET overnight plan for Thursday 2026-07-23. Today closed below baseline at score 59.7 versus 66.7 seven-day average. VPD was the slight bottleneck at 47.2% versus temperature 50.0%, but heat dominated stress at 8.36h, followed by VPD-high at 6.23h and VPD-low at 2.47h. Cost fields are unavailable/resource weight is 0, so I used runtime and water context: vent/fans ran ~11-14h, fog 1.38h, water is trending very low versus a 331 gal seven-day average, and resource conservation did not recover corridor compliance. Dew safety held with dp_margin_min_f 6.9F and 0 dp-risk hours; current margin is 8.2F. I evaluated iris-20260723-0016 at 5/10; deterministic anchor was 2 because 525 VPD-high guardrail events and 496 held guardrail events show delivery/materialization still diverged from requested posture… Result: Evaluated at the 2026-07-25 MIDNIGHT review using the plan-scoped window scorecard plus structured predicted-vs-actual. The plan governed about 76.4% of the prior day and produced a scoped score of 77.3, better than the prior full-day 65.5 and the 66.0 seven-day baseline, with dew safety preserved (daily dp_margin_min_f 5.8F, 0 dp-risk hours). However axis compliance remained weak: temp compliance 46.3% and VPD compliance 36.6%, with scoped stress about 5.02h including 3.22h heat and 2.53h VPD-high; no VPD-low stress in the scoped window. The hot/dry forecast was directionally right but overstated dryness: predicted 100F peak vs actual 96F, predicted 14% RH vs indoor proxy 56%, and predicted 855 W/m2 solar vs actual 1003 W/m2. Stress-window grading: the pre-ramp VPD-low window did not show VPD-low stress in the scoped scorecard, so wet restraint succeeded without low-side stress; the daytime VPD-high and heat windows matched the predicted kind but severity was moderate, not as severe as forecast. Rationale grading: band-coupled mist/fog plus high water budget improved the scoped score and prevented VPD-low/dew risk, but did not achieve strong VPD compliance, and transition audit shows some missed or guardrailed materialization around fog_escalation_kpa, mister_all_kpa, mister_engage_kpa, and pulse timing. Overall credit for safety, improved score, and correct stress direction; penalty for weak VPD compliance and materialization gaps. Score: 6/10

New finding: On severe hot-dry July days where forecast VPD is high-biased but solar can exceed forecast, live-ramp band-coupled wet assist can improve scoped score and prevent VPD-low/dew risk, but requested evening/unwind values are likely to be guardrailed while VPD remains above band; keep evening recovery guardrail-compatible until observed VPD is below the high edge rather than relying on clock-time taper. → Added to Lessons Learned

Hypothesis

Testing: Live-ramp severe-day wet assist: protect Vanda drying until VPD rises, then open band-coupled misters/fog aggressively and hold through evening recovery; success means lower VPD-high severity without new dew-risk hours. Expected outcome: Keep dp_risk_hours at 0, reduce VPD-high severity versus recent 7-15h days despite 100F/14% RH forecast, and keep controller-attributable misses focused on unavoidable heat capacity rather than blocked wet assist.

third severe dry day keeps live-confirmed band-coupled wet/fog assist and evening recovery while dew margin remains safe

Parameter rationale

mister_engage_kpa1.47 → 1.27; current vpd_high about 1.22 kPa; forecast crosses VPD band by 10:00 and reaches 5+ kPa by mid-afternoon

make S1 mist available near the high edge during confirmed dry stress while avoiding pre-ramp wetting

mister_all_kpa1.62 → 1.47; whole-house severe dry stress with modest zone spread; active lesson recommends all-zone near max(1.0,vpd_high+0.25)

allow all-zone rotation during broad dry stress without relying on guardrail rewrites

fog_escalation_kpa0.4 → 0.15; forecast heat/dry window overlaps 07:00-17:00 fog allowance and fog is the 7x moisture path

reduce VPD-high severity during hot-dry VENTILATE when firmware RH/dew/time gates permit fog

mister_water_budget_gal120.0 → 300.0; yesterday used only about 93 gal versus 331 gal 7-day average while scoring 58.8; today is far drier and hotter

avoid budget-limited VPD recovery during safe severe dry stress

mister_pulse_gap_s60.0 → 22.0; dry-RH lessons call for 15-25s gap and recent guardrails clamp long gaps during VPD-high stress

increase useful wet duty during confirmed VPD-high windows, then taper after observed recovery
