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 completed 00:20-02:05 MDT governed window before the WEEKLY replacement; later pre-dawn and hot/dry waypoints were unobserved. The scoped window showed 0.18 h heat stress, 0.18 h VPD-low stress, 0.05 h VPD-high stress, and 0 h cold stress. Legacy daily context closed at score/compliance 56.9, with VPD the weaker axis at 39.1% versus 53.6% temperature compliance. The short live-edge bridge reduced high-side exposure but did not establish stable corridor recovery before replacement, while low-side stress was already emerging. Dew safety held for the completed day (6.5F minimum margin, 0 dew-risk hours), and no cold stress occurred. Four plan writes were missed and two moisture thresholds mismatched in the transition audit, so materialization remained dirty. Reliable electric, gas, and total-cost fields were unavailable; total water was 280 gal and mister water 56 gal. Overall 4/10: safe dew/cold behavior and limited high-side duration, but bidirectional VPD stress, weak VPD compliance, and incomplete materialization prevented a successful result. Score: 4/10

Hypothesis

Testing: Test whether a live-edge post-midnight bridge followed by zero-wet humid-dawn protection and a staged 07:30-10:00 band-coupled handoff reduces guardrail holds while preserving dew safety and avoiding a delayed hot/dry moisture gap. Expected outcome: Through the SUNRISE replacement boundary, preserve 0 dew-risk hours and 0 cold-stress hours, keep fog and routine misting off once measured VPD recovers from the current slight high-edge miss, and avoid new low-side moisture compounding. If the sunrise plan is delayed, have band-coupled wet assist, 0.15 kPa fog escalation intent, 35% maximum mist duty, and 240 gal daily authority active by 10:00 before raw VPD exceeds 3 kPa. Reduce dirty materialization from the prior plan’s 379 VPD-high guardrail events by aligning the first segment with live-edge moisture authority and only moving to zero duty after the forecast recovery window.

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

Hypothesis

Testing: Test whether guardrail-aligned live-edge authority across three hot/dry days reduces bidirectional VPD stress and moisture-gap alerts without increasing dew risk or wasting water in recovered air. Expected outcome: For each of the next three local days: 0 dew-risk hours, 0 cold-stress hours, VPD-high stress below 6 h, VPD-low stress below 2 h, no more than one sustained vent/VPD moisture-gap warning, heat stress held near the physics-limited 5-8 h range, and actual mister water at or below 140 gal/day. Improve the next complete-day legacy corridor score above 60 while avoiding target hugging.

Humid Monday dawn followed by three physics-limited hot/dry afternoons. Forecast VPD is positively biased; all moisture remains live-edge and corridor-coupled.

Expected stress windows

vpd_lowmedium · 2026-08-17T02:00:00-06:00 to 2026-08-17T08:30:00-06:00

Zero wet duty, 10F dew floor, useful-exchange-only posture, and high relay-churn penalty.

heathigh · 2026-08-17T11:00:00-06:00 to 2026-08-17T21:00:00-06:00

45-60 minute thermal lead, solar precooling, full live-edge wet-assist authority, and acceptance of physics-limited residual heat.

vpd_highhigh · 2026-08-17T09:30:00-06:00 to 2026-08-17T23:30:00-06:00

Band-coupled +0.05/+0.25 kPa engagement, 30-40% mist-duty ceiling, 0.15-0.20 kPa fog escalation, and evening authority until recovery.

heathigh · 2026-08-18T10:30:00-06:00 to 2026-08-18T19:30:00-06:00

Repeat the live-edge hot/dry posture without widening crop bands or extending sealed-mist time.

vpd_highhigh · 2026-08-18T08:00:00-06:00 to 2026-08-18T22:00:00-06:00

Use the efficient fog path during its safe window and retain bounded mister authority after fog closes.

heathigh · 2026-08-19T11:00:00-06:00 to 2026-08-19T20:00:00-06:00

Use maximum planned thermal lead and live-edge evaporative authority; treat remaining heat as capacity-limited.

vpd_highhigh · 2026-08-19T09:00:00-06:00 to 2026-08-19T21:00:00-06:00

Maintain +0.05/+0.25 kPa wet-assist authority and avoid clock-only unwind before measured recovery.

Parameter rationale

mister_engage_kpa1.164 → 1.34; The midday served high edge is about 1.29 kPa while corrected outdoor VPD remains well above 3 kPa on all three afternoons.

Open physical mist authority near vpd_high plus 0.05 only on live demand and keep daily VPD-high stress below 6 hours.

mister_all_kpa1.264 → 1.54; Multi-zone dry pressure persists through each hot afternoon.

Escalate all-zone rotation near vpd_high plus 0.25 without pre-wetting humid or recovered air.

fog_escalation_kpa0.5 → 0.15; Peak dry stress overlaps the 07:00-17:00 fog-safe window and planned dew floors remain at least 8F.

Use the efficient fog path during confirmed hot/dry VENTILATE and reduce moisture-gap alert recurrence.

mister_water_budget_gal100.0 → 280.0; Three consecutive hot/dry afternoons create sustained live demand, while prior water totals show that authority should be available but demand-coupled.

Prevent budget exhaustion during real stress while keeping actual mister water at or below 140 gal/day.

direct_wet_stress_latest_hour21.0 → 22.0; Monday and Tuesday outdoor VPD remains elevated after 21:00.

Retain bounded evening recovery authority while keeping zero dew-risk hours and VPD-low below 2 hours/day.

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

Hypothesis

Testing: Test whether a guardrail-aligned, live-edge handoff from zero-wet humid-dawn control to +0.05/+0.25 kPa hot-dry moisture authority, 0.15 kPa daytime fog escalation, and delayed evening taper reduces bidirectional VPD stress without dew risk or unnecessary wetting. Expected outcome: Zero dew-risk hours and zero cold stress; no additional sustained VPD-low drift after the 09:00 ramp; daily VPD-low stress at or below 3 hours despite the already accrued humid-dawn interval; VPD-high stress below 6 hours; heat stress held near the physics-limited 5-8 hour range; no more than one sustained VENTILATE moisture-gap warning; mister water at or below 140 gal; next complete-day legacy corridor score above 60 without target hugging.

Conditions

Outdoor peak

93.0°F

RH minimum

13.0%

Solar peak

850.0 W/m²

Cloud average

50.0%

Active VPD-low alert at a cool humid dawn, followed by an abrupt clear-sky ramp to extreme hot-dry conditions; cloud cover becomes highly variable after peak solar. Forecast VPD is positively biased, so all wetting remains live-edge and band-coupled.

Expected stress windows

vpd_lowhigh · 2026-08-17T05:15:00-06:00 to 2026-08-17T09:00:00-06:00

Zero wet duty, 10F requested dew floor, useful-exchange-only posture, and high churn penalty while alert 10320 remains active.

heathigh · 2026-08-17T10:30:00-06:00 to 2026-08-17T21:00:00-06:00

35-60 minute thermal lead, 1.2F solar precooling, live-edge evaporative assist, and acceptance of physics-limited residual heat.

vpd_highhigh · 2026-08-17T09:30:00-06:00 to 2026-08-17T23:00:00-06:00

Use +0.05/+0.25 kPa band-coupled moisture engagement, 30-40% duty, 0.15-0.18 kPa fog escalation during the safe window, and bounded evening mister authority until recovery.

Parameter rationale

mister_engage_kpa1.089 → 1.34; The midday served VPD high edge is about 1.29 kPa while corrected outdoor VPD approaches 4 kPa.

Materialize the +0.05 kPa live-edge intent without humid-dawn pre-wetting and keep VPD-high stress below 6 hours.

mister_all_kpa1.239 → 1.54; Persistent multi-zone dry pressure is expected through the full hot window.

Materialize all-zone escalation near the midday high edge plus 0.25 kPa without inventing a south priority from null VPD.

fog_escalation_kpa0.5 → 0.15; Peak dry stress overlaps the 07:00-17:00 fog-safe window and the planned dew floor remains 8F.

Use the efficient fog path during confirmed hot-dry VENTILATE and limit sustained moisture-gap warnings to at most one.

mister_water_budget_gal100.0 → 280.0; Yesterday used 56 gal of mister water and today brings a longer 93F/13% RH stress window.

Avoid budget-limited high-side recovery while keeping actual mister water at or below 140 gal.

direct_wet_stress_latest_hour21.0 → 23.0; Raw outdoor VPD remains 2.9 kPa at 21:00 and 2.0 kPa at 23:00 before overnight recovery.

Retain bounded evening high-side recovery authority while the sticky guardrail prevents clock-only unwind before observed recovery.
