Validating previous cycle: iris-20260815-0613

Previous hypothesis: SUNRISE plan for Saturday 2026-08-15. Friday closed at score/compliance 63.6 versus a 68.5 seven-day average. Legacy VPD compliance was the weaker axis at 45.9% versus 55.5% temperature compliance. Heat was narrowly dominant at 8.66 h, with VPD-low nearly equal at 8.30 h; VPD-high was 1.86 h and cold was 0. Water was 86 gal including 18 gal misting versus a 237 gal seven-day average, so water was down and not binding. Reliable gas, electric, and total-cost fields are null, so utility cost cannot be attributed to heating versus cooling. previous_plan_validation: iris-20260814-0613 scored 5/10 versus deterministic anchor 6, a non-material one-point difference. Its governed window scored 60.8, with VPD compliance 44.1% versus temperature 54.3%; stress was 4.46 h heat, 4.34 h VPD-low, 0.93 h VPD-high, and 0 cold. The forecast temperature peak was close at 89.0F predicted versus 87… Result: Elapsed evaluation through the 06:15 MDT SUNRISE replacement boundary. The plan correctly anticipated a cool, saturated pre-dawn regime and preserved safety: current climate is 69.8F, VPD 0.56 kPa, RH 78%, dew margin 7.2F, IDLE, with all wetting, fog, vent, fans, and heaters off; cold stress was 0 and dew-risk was 0 h. However, the governed-window score/compliance was only 49.9, with VPD the bottleneck at 32.6% versus 56.2% temperature compliance. Window stress was 0.84 h VPD-low, 0.22 h heat, 0.08 h VPD-high, and 0 h cold. Alert 10311 remains open for sustained low-side drift, so the experiment did not demonstrate that useful-exchange-only plus zero wetting prevented VPD-low compounding. Later dry-ramp waypoints were unobserved and receive no credit or penalty. Materialization was also dirty: the assembled transition audit shows 8 missed writes, including direct-wet safety/override fields and cooling staging. Overall 4/10: correct regime diagnosis and safe dew/cold outcome, but weak VPD corridor recovery, an active low-side warning, and missed materialization. Score: 4/10

Hypothesis

Testing: Test whether a simple useful-exchange-only, zero-wet humid-night posture followed by one delayed live-edge handoff preserves dew safety without repeating low-side compounding or guardrail-heavy materialization. Expected outcome: From midnight-09:30 MDT, keep fog and mister duty at zero, maintain 0 dew-risk hours with house dew margin at or above 5F, avoid cold stress and heater/vent whipsaw, and obtain monitor-proven recovery of alert 10311 if useful dehumidification opportunity develops. At 10:30, do not pre-wet; open moisture authority only after a live crop-band high-edge breach. Through the 13:30 handoff, target less than 0.5 h VPD-high stress and less than 1 h heat stress, with water nonbinding.

Validating previous cycle: iris-20260815-1959

Previous hypothesis: SUNSET plan for Saturday 2026-08-15. Today’s partial-day score is 54.5 versus a 66.9 seven-day average. Graded attributable compliance and reliable resource terms are unavailable. Legacy VPD compliance was the bottleneck at 49.9% versus 56.7% temperature compliance. Heat dominated at 6.58 h, followed by 5.54 h VPD-low, 2.17 h VPD-high, and 0 cold. Reliable electric, gas, water-cost, and total-cost fields are null, so cost cannot be attributed to heating versus cooling. The assembled meter context shows only 29 gal total water versus a 193 gal seven-day average, so water was below trend and not binding. Previous-plan validation: iris-20260815-0016 scored 5/10 and matched deterministic anchor 5. Its humid pre-dawn diagnosis preserved a 6.5F replacement-time dew margin and 0 cold, but window score was only 54.4 and VPD compliance 49… Result: Evaluated through the 19:57 MDT SUNSET replacement boundary. The governed-window score was 52.9, with VPD compliance the bottleneck at 35.0% versus 48.5% temperature compliance. Stress was 2.53 h VPD-high, 2.36 h heat, 2.18 h VPD-low, and 0 h cold. The experiment’s VPD-high-under-4h prediction succeeded and dew/cold safety held (daily minimum dew margin 6.5F, 0 dew-risk hours, 0 cold stress). However, overall corridor performance remained weak, the house ended in VENTILATE at 76.8F/1.23 kPa with alert 10318 open for a 15-minute vent/VPD moisture-assist gap, and the transition audit recorded 18 missed writes including cooling stage, moisture cadence, and direct-wet guard fields. Total water was 279 gal versus a 136 gal seven-day average, but misting-only water and reliable gas/electric/total-cost fields were unavailable, so the ⇐80 gal mister-water and cost hypotheses cannot be credited. Forecast direction was correct (humid dawn followed by hot/dry conditions), but low-side and high-side VPD stress both remained material. Overall 5/10: the live-edge strategy bounded VPD-high and preserved safety, but poor VPD compliance, unresolved moisture-path delivery, high total water context, and dirty materialization prevented a good outcome. Score: 5/10

Hypothesis

Testing: Test whether live-edge-only wet assist with a 0.15 kPa fog escalation during the 14:00-17:00 hot/dry window can hold VPD-high stress below 4 hours without pre-wetting the humid dawn or exceeding 80 gallons of mister water. Expected outcome: Preserve 0 dew-risk hours and 0 cold-stress hours; keep VPD-high stress below 4 hours and heat stress below 6 hours despite physics-limited afternoon conditions; keep mister water at or below 80 gallons; avoid wet actuation before a live high-edge breach and retain band-coupled recovery authority through 21:00 if VPD remains high.

vpd_lowhigh · 2026-08-16T06:00:00-06:00 to 2026-08-16T09:30:00-06:00

Zero wet duty, 11-12F requested dew floor, useful-exchange-only economizer posture, and stable relay dwell.

heathigh · 2026-08-16T11:30:00-06:00 to 2026-08-16T20:00:00-06:00

Use 45-minute thermal lead and 1.2F solar precooling while accepting physics-limited residual heat above the served edge.

vpd_highhigh · 2026-08-16T11:30:00-06:00 to 2026-08-16T21:00:00-06:00

Use live-edge-only +0.05/+0.25 kPa wet assist, 28-35% duty, 0.15-0.18 kPa fog escalation, and retain evening authority until measured recovery.

Parameter rationale

mister_engage_kpa1.214 → 1.34; Midday band_vpd_high is about 1.29 kPa while raw VPD rises above 2 kPa from noon.

Open physical mist authority near vpd_high plus 0.05 only after a live high-edge breach, with no humid-dawn pre-wetting.

mister_all_kpa1.264 → 1.54; Corrected afternoon VPD remains roughly 2.4-2.8 kPa despite positive forecast bias.

Escalate broad mist rotation near vpd_high plus 0.25 only when measured multi-zone stress persists.

mister_pulse_gap_s60.0 → 22.0; The 11:30-18:00 hot/dry window overlaps solar up to 835 W/m2 and outdoor RH of 20-43%.

Provide effective evaporative recovery during confirmed stress while the evening segment reduces duty before humid overnight conditions.

fog_escalation_kpa0.5 → 0.15; The strongest dry stress overlaps the 07:00-17:00 firmware fog window and the plan preserves an 8F dew floor.

Use the efficient fog path during hot/dry VENTILATE and keep VPD-high stress below 4 hours.

mister_water_budget_gal100.0 → 200.0; Saturday used only 12 gal misting and 29 gal total water versus a 193 gal seven-day total-water average.

Prevent the afternoon response from becoming budget-limited while keeping expected mister water at or below 80 gal.

direct_wet_stress_latest_hour21.0 → 21.0; Raw outdoor VPD remains above 1.6 kPa through 20:00 before gradual recovery.

Retain bounded evening recovery authority until measured VPD recovers, without extending routine wetting into the late night.

Reflection

Validating previous cycle: iris-20260816-0615

Previous hypothesis: SUNRISE plan for Sunday 2026-08-16. Saturday closed at score/compliance 58.0 versus a 66.9 seven-day average. VPD was the bottleneck at 47.8% versus 56.2% temperature compliance. Heat narrowly dominated at 7.66 h, with VPD-low nearly equal at 7.60 h; VPD-high was 2.53 h and cold was 0. Reliable electric, gas, and total-cost fields are null, so utility cost cannot be attributed to heating versus cooling. Water was only 29 gal, including 12 gal misting, versus a 193 gal seven-day average, so water was sharply below trend and not binding. Previous-plan validation: iris-20260816-0025 scored 4/10 and matched deterministic anchor 4. Through the 06:15 replacement boundary it correctly anticipated saturated pre-dawn conditions and preserved a 7.2F current dew margin, 0 dew-risk hours, and 0 cold stress, but its governed-window score was only 49.9 and VPD compliance was 32.6% versus 56… Result: Evaluated only the elapsed prior-local-day window from the 19:57/20:00 MDT activation through midnight; later pre-dawn and Monday hot/dry handoff waypoints were unobserved and receive no credit or penalty. Sunday closed at planner score/compliance 56.9, below the 7-day average 62.3; legacy VPD compliance was the bottleneck at 39.0% versus 53.6% temperature compliance, with 7.51 h VPD-high, 5.18 h VPD-low, 7.45 h heat, and 0 cold. During this plan’s elapsed evening window, VPD declined from roughly 1.21 kPa at 20:00 to 0.87 kPa at midnight, but current action proof at 00:16 still showed VPD about 0.069 kPa above the dispatcher-owned high edge, so the experiment’s goal of clearing the live VPD-high gap before the zero-wet night was not fully met. Dew safety remained strong (current margin about 11.37F; no disease-risk signal), and current crop observations remained generally healthy. The scoped WINDOW SCORECARD is all zeros despite fresh telemetry and the persistent edge miss, so it is treated as a rollup/data gap rather than zero stress. Materialization was mixed: 29 already-at-value, 13 matched, 4 guardrailed, 1 held by guardrail, and 4 missed; missed writes included direct-wet stress latest-hour/dew-margin requests, while sticky moisture guardrails held conservative moisture requests until observed recovery. Overall 4/10: correct regime sequencing and safe dew/cold outcome, with a meaningful downward VPD trend, but the live high-side gap was not cleared, corridor performance for the completed day was weak, and materialization remained dirty. The pre-dawn VPD-low and Monday heat/VPD-high predictions are still unobserved. Score: 4/10

Hypothesis

Testing: Test whether a short band-coupled evening recovery followed by zero-wet, useful-exchange-only overnight posture clears the live VPD-high gap without compounding pre-dawn VPD-low. Expected outcome: Clear the live sunset vent/VPD moisture gap before the cool-night reversal; preserve 0 dew-risk hours and 0 cold-stress hours; hold overnight VPD-low stress below 2.5 hours with no wet duty after 21:30 and stable useful-exchange-only drying. If SUNRISE replacement is delayed, restore live-edge moisture and precooling authority by 08:30 for Monday’s extreme hot/dry ramp.

Clear cooling night to 58F with rising RH and low-VPD risk, then a rapid extreme hot/dry Monday ramp. Forecast VPD is positively biased, so wet assist remains live-edge-only.

Expected stress windows

vpd_highmedium · 2026-08-16T19:57:00-06:00 to 2026-08-16T21:30:00-06:00

Use +0.05/+0.25 kPa band-coupled mister authority with 25% duty while the 14.5F dew margin is safe; fog is unavailable after 17:00.

vpd_lowhigh · 2026-08-17T00:00:00-06:00 to 2026-08-17T08:30:00-06:00

Use zero wet duty, 10-11F requested dew floors, useful-exchange-only economizer posture, and high churn penalty.

heathigh · 2026-08-17T10:30:00-06:00 to 2026-08-17T20:00:00-06:00

If sunrise replacement is delayed, use 45-minute thermal lead, 1.2F solar precooling, and early live-edge evaporative authority while accepting physics-limited residual heat.

vpd_highhigh · 2026-08-17T09:30:00-06:00 to 2026-08-17T22:00:00-06:00

Use live-edge +0.05/+0.25 kPa moisture engagement, 30% duty, 0.15 kPa fog escalation, and a 240 gal budget fallback without forecast-only pre-wetting.

Parameter rationale

mister_engage_kpa0.954 → 1.42; Pre-dawn raw VPD falls to 0.20-0.53 kPa while the midnight band high is about 1.17 kPa.

Keep physical wet assist closed overnight, then restore near-edge engagement in the 08:30 fallback.

mister_all_kpa1.154 → 1.62; The overnight forecast is broadly humid and does not justify all-zone escalation.

Prevent unnecessary all-zone moisture overnight, then restore band-coupled daytime escalation.

mister_pulse_gap_s26.25 → 60.0; Forecast RH rises to 82-88% and humidity holds better when the house is sealed overnight.

Widen overnight evaporation dwell and avoid moisture/relay cycling while wet duty is zero.

fog_escalation_kpa0.15 → 0.5; Fog is firmware-blocked after 17:00 and overnight VPD-low risk dominates.

Produce no overnight fog and restore 0.15 kPa efficient daytime escalation at the 08:30 handoff.

direct_wet_stress_min_dew_margin_f8.0 → 11.0; Clear-night cooling reaches 58-61F while RH rises above 80% near dawn.

Preserve 0 dew-risk hours and block wet recovery from compressing the pre-dawn dew margin.

mister_water_budget_gal250.0 → 140.0; Overnight wet duty is zero and total water today was 279 gal versus a 136 gal seven-day average.

Avoid irrelevant overnight water authority without constraining the 240 gal hot/dry fallback after 08:30.
