Solar peak planning checkpoint13:07SOLAR_MAXackedAcknowledged: SOLAR_MAX no change: live solar 288 W/m² is above the refreshed 14:00 forecast of 94 W/m² (and its bias-corrected prior), but remains far below the SUNRISE-plan peak assumption of 722 W/m². Indoor VPD is 1.16 kPa with a non-rising two-hour pattern after brief peaks to 1.28/1.24; occupied east and west zones are 0.97/1.02 kPa, dew margin is safe at 10.8°F, controller is IDLE, and all wet/cooling equipment is off... Resolved 13:07 MDT.
Peak Stress15:06TRANSITIONackedAcknowledged: Peak-stress checkpoint is tracking the active sunrise plan: live temperature is 84.6F and VPD 1.23 kPa with a healthy 11.1F dew margin; occupied east/west VPD readings are 1.12/0.99 kPa, the controller is IDLE, and vent, fans, fog, and all misters are off. Recent effective settings already provide band-coupled moisture support (engage 1.054 kPa, all-zone 1.204 kPa, 30 s pulse gap, fog escalation 0.30), while the next planned taper/rebound waypoints remain active... Resolved 15:07 MDT.
Forecast deviation18:00FORECAST_DEVIATIONackedAcknowledged: 0.51 in/h precipitation is a real transient convective/nowcast miss: outdoor temperature fell 72.1→67.2F and RH rose 61→81% in 20 minutes. Indoor climate remains safe and inside the served corridor at 79.8F, VPD 0.96 kPa, dew margin 9.7F; controller is IDLE and all climate/wet equipment is off. Fresh forecast already carries the humid overnight regime, so no tunable change is warranted for this brief shower. Resolved 18:00 MDT.
Decline18:58TRANSITIONackedAcknowledged: Decline is tracking the existing taper: 78.7F and 0.88 kPa are inside the active 71.8-81.8F / 0.39-0.94 kPa house corridor; east 1.09 and west 0.74 remain within their zone corridors, dew margin is safe at 9.0F, controller is IDLE, and all vent/fan/fog/mister/heater equipment is off. Effective settings are already conservative for the humid overnight rebound (mister_engage_kpa 1.254, pulse gap 60s, fog escalation 0.50), so no redundant tunable change is warranted.

Validating previous cycle: iris-20260814-0613

Previous hypothesis: SUNRISE plan for Friday 2026-08-14. Thursday closed at planner score 57.2 versus a 70.4 seven-day average. Graded attributable fields and reliable electric/gas/total-cost fields remain unavailable. Legacy temperature compliance was the narrower axis at 49.6% versus 53.3% VPD compliance. Heat dominated at 9.95 h, followed by 7.23 h VPD-high, 1.36 h VPD-low and 0 cold. Water was 140 gal, including 28 gal misting, versus a 274 gal seven-day average, so water use was down sharply and was not the constraint; a gas-versus-electric cost diagnosis cannot be made from null utility fields. previous_plan_validation: iris-20260813-2001 scored 6/10 versus deterministic anchor 3. I credited the successful evening VPD-high recovery, 7.4F minimum dew margin, 0 dew-risk hours, 0 cold stress, and only 0.06 h VPD-high in its short window… Result: Elapsed governed-window evaluation through replacement at 06:15 MDT. Window score/compliance was 54.4; legacy VPD compliance was the weaker axis at 49.9% versus 56.6% temperature compliance. Stress was 1.67 h heat, 1.41 h VPD-low, 0.55 h VPD-high, and 0 h cold. The predicted saturated pre-dawn VPD-low regime materialized, while the later dry/solar pulse and convective-reversal waypoints were unobserved and are unproven rather than failed. Dew safety was preserved: the replacement-time state was 69.6F, 0.51 kPa VPD, 80% RH with a 6.5F dew margin; daily dew-risk remained 0 h. Zero-wet humid-night posture avoided fog/mister compounding but did not restore strong VPD corridor performance, reinforcing that suppression alone is insufficient. The broader assembled transition audit reports dirty materialization/missed writes for neighboring plan periods, while this formal window grade uses the scoped scorecard. Overall 5/10: safe dew/cold outcome and correct regime diagnosis, but mediocre corridor compliance and persistent low-side VPD; later hypotheses were not observed. Score: 5/10

Hypothesis

Testing: Stage a no-wet saturated-night posture into a forecast-discounted, live-edge-only noon assist window, then taper before the convective humidity reversal; test whether this avoids both overnight VPD-low amplification and delayed daytime VPD-high. Expected outcome: Keep dew-risk hours at 0 and minimum dew margin at or above 5F; produce no fog or mister duty before 10:15 MDT; avoid pre-wetting while VPD is inside/below the crop corridor; if the noon dry ramp materializes, keep VPD-high stress below 1.5 h through 16:30 with no budget limitation; return to zero wet duty by the humid afternoon reversal.

Validating previous cycle: iris-20260814-2000

Previous hypothesis: SUNSET plan for Friday 2026-08-14. Today closed at planner score/compliance 62.7 versus the 68.5 seven-day average. Graded attributable fields are unavailable. VPD was the weaker legacy axis at 47.6% versus 57.0% temperature compliance. Heat was the largest stress at 6.80 h, narrowly ahead of VPD-low at 6.04 h; VPD-high was 1.85 h and cold was 0. Reliable electric, gas, water-cost, and total-cost fields are null, so gas-versus-electric cost attribution is unavailable. The assembled meter context shows 86 gal total water versus a 237 gal seven-day average, so water was below trend and not binding. previous_plan_validation: iris-20260814-0016 scored 6/10, matching deterministic anchor 6. Its humid pre-dawn posture preserved 0 dew-risk hours and 0 cold stress but still allowed 1.50 h VPD-low in its governed window; later daytime goals were unobserved… Result: Elapsed replacement-boundary evaluation through sunset. The governed-window score/compliance was 46.6, with legacy VPD compliance weaker at 42.7% versus 48.4% temperature compliance. Stress was 3.30 h heat, 2.78 h VPD-low, 1.08 h VPD-high, and 0 h cold. The predicted saturated dawn, daytime heat/dry ramp, and humid-evening reversal all materialized directionally. The measurable goals of keeping VPD-high below 2 h and heat below 5 h succeeded, and dew/cold safety was preserved: today’s minimum dew margin was 5.6F, dew-risk 0 h, cold stress 0 h; the sunset state recovered to 73.2F and 0.78 kPa VPD with a 9.5F dew margin. However, VPD-low remained material at 2.78 h, overall corridor performance was poor, and the daily score was only 54.5 versus the 66.9 seven-day average. Assembled water evidence was only 29 gal versus a 193 gal seven-day average, so the budget was not binding. The broader transition audit shows 102 matched, 2 guardrailed, 5 mismatches, and 25 missed writes, including repeated direct-wet guard and cooling-stage materialization misses; this formal evaluation may report a narrower guardrail scope. Overall 5/10: correct live-edge strategy limited high-side VPD and preserved dew safety with low water, but low-side VPD, heat exposure, weak compliance, and dirty materialization prevented a good outcome. Score: 5/10

Hypothesis

Testing: Use a forecast-discounted, live-edge-only moisture window between a saturated dawn and convective afternoon reversal; test whether it limits both daytime VPD-high and post-storm VPD-low without target hugging or unnecessary water. Expected outcome: Keep dew-risk hours at 0 with minimum dew margin at or above 5F; avoid all fog/mister duty before 10:15 while VPD is low; keep daytime VPD-high stress below 2 h and heat stress below 5 h if the forecast peak stays near 84F; taper wet assist by the 14:00-15:00 humidity reversal; keep mister water below 60 gal and avoid budget limitation.

vpd_lowhigh · 2026-08-15T06:00:00-06:00 to 2026-08-15T10:15:00-06:00

Zero wet duty, 11-12F requested dew floor, stable dehumidification opportunity, and no saturated-air exchange without a useful advantage.

vpd_highmedium · 2026-08-15T11:00:00-06:00 to 2026-08-15T14:30:00-06:00

Use forecast-discounted, live-edge-only +0.05/+0.25 kPa wet assist, 25% duty, and 0.20 kPa fog escalation while dew margin is safe.

heathigh · 2026-08-15T11:30:00-06:00 to 2026-08-15T15:30:00-06:00

Use 45-minute thermal lead and 1.2F solar precooling, retaining authority through cloud uncertainty while accepting physics-limited residual heat.

vpd_lowhigh · 2026-08-15T18:00:00-06:00 to 2026-08-16T04:00:00-06:00

Return to zero wet duty, 12F requested dew floor, 0.50 kPa fog escalation, and high resource/churn sensitivity for 76-92% outdoor RH.

Parameter rationale

mister_engage_kpa1.115 → 1.34; Midday crop-owned VPD high is about 1.29 kPa and the plan requests +0.05 kPa engagement only after the live edge is crossed.

Avoid pre-wetting the saturated dawn while opening physical mister authority promptly during a confirmed dry breach.

mister_all_kpa1.215 → 1.54; The noon-14:00 raw VPD reaches 2.27-2.60 kPa but carries about +1 kPa positive bias.

Escalate all-zone rotation near vpd_high plus 0.25 only if broad measured stress persists.

mister_pulse_gap_s60.0 → 30.0; The useful dry window is short and overlaps the 663-722 W/m2 solar ramp.

Provide bounded midday recovery without carrying hot/dry cadence into the convective humid reversal.

fog_escalation_kpa0.5 → 0.2; The dry ramp occurs inside the 07:00-17:00 fog window, while the peak segment preserves an 8F dew floor.

Use efficient fog only after a confirmed high-edge breach and return to suppression before humid evening.

mister_water_budget_gal160.0 → 200.0; Friday used only 18 gal misting and 86 gal total water versus 237 gal seven-day average.

Prevent safe midday recovery from becoming budget-limited while keeping expected mister water below 60 gal.

direct_wet_stress_latest_hour21.0 → 19.0; Outdoor RH rises to 83-92% from 19:00 through midnight after the convective reversal.

Stop bounded daytime recovery authority before the humid-night low-side risk.

Reflection

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 prior-local-day portion only, approximately 19:59-00:00 MDT; the 02:30, 06:30, and 10:30 Sunday waypoints were unobserved and receive no credit or penalty. Saturday closed at planner score/compliance 57.9 versus a 66.9 seven-day average; legacy VPD compliance was the weaker axis at 47.8% versus 56.2% temperature compliance. Daily stress was 7.66 h heat, 7.55 h VPD-low, 2.53 h VPD-high, and 0 h cold; water was 29 gal including 12 gal misting, so water was not binding. The sunset plan correctly predicted a humid, VPD-low overnight regime: house VPD fell from about 0.71 kPa at 20:00 to 0.50 kPa after midnight, and alert 10311 opened for 45+ minutes below the commanded band. Its zero-wet posture was mostly achieved after 20:21 and current fog/misters are off, preserving dew safety: current dew margin is 7.2F, the daily minimum was 5.6F, dew-risk remained 0 h, and cold stress remained 0. However, the core experiment did not avoid low-side VPD compounding; DEHUM_VENT and vent activity did not restore the corridor, and the active drift alert remains open. The proposed hot/dry 10:30 handoff was not observed. Materialization was dirty: the transition audit reports 14 missed writes, including dew-guard, wet-cutoff, cooling-stage, and moisture-threshold requests. The per-plan window scorecard reports all-zero compliance and stress despite fresh telemetry and the active warning; this is treated as a rollup/data gap, not as a successful zero-stress result. Overall 4/10: correct regime diagnosis and safe dew/cold/fog outcome, but weak corridor recovery, active VPD-low drift, and missed materialization. Score: 4/10

Hypothesis

Testing: Use a strict zero-wet, high-dew-floor humid-night posture followed by one simple live-edge morning handoff; test whether this avoids both overnight VPD-low compounding and guardrail-heavy daytime materialization. Expected outcome: Through the overnight window, keep fog and mister duty at zero while outdoor RH rises to 96-100%, hold dew-risk at 0 h with minimum house dew margin at or above 5F, avoid cold stress and heater/vent whipsaw, and improve low-side VPD handling through stable useful exchange rather than target hugging. If the sunrise cycle is delayed, the 10:30 fallback should keep moisture closed until a live high-edge breach, then provide band-coupled assist for the forecast hot/dry ramp; target Sunday daytime VPD-high below 3 h and heat below 6 h, with water remaining nonbinding.

Conditions

Outdoor peak

86.0°F

RH minimum

23.0%

Solar peak

832.0 W/m²

Cloud average

52.0%

Saturated 61-62F overnight with 96-100% RH and near-zero raw VPD, followed by a rapid variable-cloud hot/dry ramp toward 86F. Forecast VPD is positively biased, so live crop-band edges govern wet assist.

Expected stress windows

vpd_lowhigh · 2026-08-15T21:00:00-06:00 to 2026-08-16T09:30:00-06:00

Zero wet duty, 10-13F requested dew floor, stable dehumidification opportunity, and no saturated-air exchange without useful dew-point advantage.

heathigh · 2026-08-16T13:30:00-06:00 to 2026-08-16T19:30:00-06:00

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

vpd_highhigh · 2026-08-16T14:00:00-06:00 to 2026-08-16T21:00:00-06:00

Use forecast-discounted, live-edge-only +0.05/+0.25 kPa wet assist, 25% duty, and 0.20 kPa fog escalation while dew margin is safe.

Parameter rationale

mister_engage_kpa1.254 → 1.34; Sunday midday crop-owned VPD high is about 1.29 kPa and raw VPD climbs above 2 kPa after 14:00.

Keep wetting closed through the saturated morning, then open physical mister authority near vpd_high plus 0.05 only after a live breach.

mister_all_kpa1.304 → 1.54; Sunday raw VPD reaches 2.14-3.26 kPa from 14:00-18:00, but carries about +0.96 kPa positive bias.

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

mister_pulse_gap_s60.0 → 30.0; The useful dry window begins after the 10:30 handoff and overlaps solar rising toward 832 W/m2.

Provide bounded hot/dry recovery after a live breach without carrying short cadence into the saturated night or morning.

fog_escalation_kpa0.5 → 0.2; The dry ramp enters the 07:00-17:00 fog window while the fallback maintains an 8F dew floor.

Use the efficient fog path only during confirmed daytime VPD-high stress and produce zero fog overnight.

mister_water_budget_gal120.0 → 180.0; Saturday total water was only 29 gal versus a 193 gal seven-day average, while Sunday may reach 86F and 23% RH.

Prevent a safe live-edge daytime response from becoming budget-limited while keeping overnight wet duty at zero.

direct_wet_stress_latest_hour21.0 → 20.0; Sunday dry stress may persist after the 17:00 fog cutoff, but tonight is saturated and requires no late wetting.

Keep a bounded evening recovery path for Sunday without carrying routine wetting deep into the following night.
