Midnight Posture00:00TRANSITIONacked-00:01Acknowledged: Midnight check: current climate is stable (63.9F, VPD 0.51 kPa, RH 75%, dew-point margin 8.1F) with IDLE/heat1 posture appropriate for the 36F pre-dawn forecast. Active plan already has 05:00 overnight heat-stability and 08:30 dry-ramp preconditioning waypoints; no tunable change needed at this transition. Previous 2026-05-01 plan was evaluated separately. Resolved 00:01 MDT.
New forecast data00:51FORECASTacked-00:52Acknowledged: Forecast update checked against active plan iris-20260501-1956 and current setpoints. New 24h forecast still matches the existing Saturday dry-ramp posture: clear skies after dawn, peak ~72F, RH 9-13%, solar near 895 W/m2, with existing 05:00 heat-stability and 08:30 aggressive mist/fog preconditioning waypoints already scheduled. No tunable change needed. Resolved 00:52 MDT.
New forecast data01:52FORECASTacked-01:53Acknowledged: Forecast update matches the governing plan: Saturday still shows clear dry ramp after 09:00 with RH ~9-13%, solar peak ~895 W/m2, and temp peak ~72F. Existing 08:30 waypoint already preconditions with aggressive mist/fog posture for this VPD window, so no tunable changes needed. Resolved 01:53 MDT.
New forecast data02:52FORECASTacked-02:53Acknowledged: Forecast update checked against active plan iris-20260501-1956. The new 24h forecast matches the already-planned Saturday dry-ramp posture: clear skies, solar near 895 W/m2, RH falling to 8-14%, and peak temp around 72F. Existing 08:30 waypoint already preconditions with aggressive mist/fog settings for the 10:00-17:00 VPD ramp, so no tunable or plan change is needed. Resolved 02:53 MDT.
New forecast data03:52FORECASTacked-03:53Acknowledged: Forecast update matches the active Saturday dry-ramp plan: clear skies, RH ~8-13%, solar near 900 W/m², and a 10:00-19:00 high-VPD window were already anticipated. Future waypoints at 05:00 and 08:30 carry the planned pivot from overnight heat stability to aggressive mist/fog preconditioning, so no tunable change is needed. Resolved 03:53 MDT.
New forecast data04:53FORECASTacked-04:53Acknowledged: Forecast update matches the active Saturday dry-ramp plan: clear sky, peak ~72F, RH 8-13%, solar near 900 W/m2. Existing 08:30 waypoint already lowers mist thresholds, shortens pulse gap, increases VPD weighting, and brings fog escalation to 0.30 for the 10:00-17:00 VPD ramp; no tunable change needed. Resolved 04:53 MDT.
Pre Dawn05:00TRANSITIONacked-05:01Acknowledged: Pre-dawn check: current climate is safe and stable (63.5F, VPD 0.48 kPa, dew-point margin 7.7F), ESP32 is IDLE with heaters active as expected for the 39F outdoor pre-dawn low, and the active plan already pivots at 08:30 to aggressive dry-ramp mist/fog posture for today’s clear RH 8-13% / ~900 W/m2 solar window. No tunable change needed. Resolved 05:01 MDT.
New forecast data05:53FORECASTacked-05:54Acknowledged: Forecast update matches the governing plan: clear, very dry Saturday with solar near 900 W/m2 and RH falling to single digits was already anticipated by the 08:30 dry-ramp waypoint. No temperature/cloud/humidity shift large enough to justify replacing the plan. Resolved 05:54 MDT.

New forecast data08:52FORECASTacked-08:54Acknowledged: Forecast matches the just-written 08:39 dry-solar plan: clear skies, RH falling to 6-13%, solar peak near 900 W/m2, and current setpoints already use aggressive VPD posture (mister_engage_kpa 1.2, mister_all_kpa confirmed at 1.55 floor, 15s gap, vpd_weight 3.0, fog_escalation_kpa 0.2). No material forecast shift or additional safe tunable change needed. Resolved 08:54 MDT.
New forecast data09:53FORECASTacked-09:54Acknowledged: Forecast update aligns with active dry-solar plan iris-20260502-0839: next 24h remains clear, very dry, and within expected temperature range; current waypoints already hold aggressive mist/fog posture (engage 1.2, all 1.55 executable floor, 15-20s mist gap, fog_escalation_kpa 0.2). No significant forecast shift requiring tunable changes. Resolved 09:54 MDT.
New forecast data11:48FORECASTacked-11:48Acknowledged: Forecast update reviewed: next-24h remains clear, hot-dry, and within the dry-solar posture already covered by plan iris-20260502-0839. Current tunables are confirmed on ESP32, VPD is in band, dew-point margin is safe, and no >5F/cloud/humidity shift requires a plan change. Resolved 11:48 MDT.
New forecast data12:47FORECASTacked-12:49Acknowledged: Forecast checked against active plan and current setpoints. The update matches the governing dry-clear Saturday posture: RH remains 8-11% with solar tapering from ~900 to ~120 W/m2, and the plan already has aggressive midday mist/fog settings plus a late-day relaxation to reduce VPD-low overshoot. Current greenhouse VPD is controlled near 1.06 kPa with no dew-point risk, so no tunable change is warranted. Resolved 12:49 MDT.

Peak Stress14:58TRANSITIONtimed_out-unknownDelivery recorded without a public plan write.
New forecast data15:48FORECASTacked-15:49Acknowledged: No forecast-driven setpoint change needed. The 13:49 plan already extended aggressive dry-solar VPD posture through the 16:30-19:30 shoulder, matching the refreshed 24h forecast: RH remains ~8-9%, solar declines 692→120 W/m2, and current tunables already hold short mist gaps plus low fog escalation. No significant temperature/cloud/humidity shift relative to the active plan. Resolved 15:49 MDT.
New forecast data16:48FORECASTacked-16:49Acknowledged: Forecast update reviewed against active plan iris-20260502-1349 and current setpoints. The new 24h forecast still matches the dry late-afternoon shoulder and aggressive Sunday VPD posture already covered by the 19:30 and Sun 07:00 waypoints; no significant temperature, cloud, or humidity shift requires a new plan. Resolved 16:49 MDT.
Tree Shade16:58TRANSITIONtimed_out-unknownDelivery recorded without a public plan write.
New forecast data18:41FORECASTacked-18:42Acknowledged: Forecast update reviewed against active plan. No change needed: the Sunday 07:00 waypoint already preconditions for the dry VPD ramp with engage 1.2 kPa, all-zone 1.6 kPa, 20s gap, high VPD weighting, short sealed-vent cap, and fog_escalation 0.3. New forecast is still dry but not materially beyond the current dry-day posture; tonight's remaining dry air has low/no solar and fog is outside its time window. Resolved 18:42 MDT.
Decline18:57TRANSITIONacked-18:58Acknowledged: Decline transition checked: greenhouse is IDLE at 68.7°F / 0.67 kPa VPD with vent/fog/misters off and heat1 maintaining the evening band. Active setpoints already reflect the intended evening relaxation (mister_engage_kpa 1.6, mister_all_kpa 2.1, pulse_gap 45s, fog_escalation_kpa 0.6), and south VPD is already low (0.32), so further humidity aggression would risk overshoot. No tunable change needed. Resolved 18:58 MDT.
New forecast data19:40FORECASTacked-19:41Acknowledged: Forecast checked against active plan and setpoints. The new 24h outlook is very dry tomorrow (RH 6-10%, outdoor VPD near 3 kPa) but the existing 07:00 waypoint already preconditions for that dry-solar ramp with aggressive mist/fog posture (mister_engage_kpa 1.2, mister_all_kpa 1.6, 20s gap, fog_escalation_kpa 0.3, short sealed-vent cap). Afternoon cloud cover lowers heat/solar risk, so no additional tunable change is justified for this routine forecast update. Resolved 19:41 MDT.

New forecast data20:40FORECASTacked-20:41Acknowledged: 20:40 forecast update checked: next-24h forecast remains aligned with active plan iris-20260502-1958. Sunday peak temp is ~79F vs planned 78F, RH minimum ~8% vs planned 6%, cloud cover remains predominantly overcast/uncertain, and the active plan already pivots to aggressive dry-ramp mist/fog at 06:30-09:00. No tunable change needed. Resolved 20:41 MDT.
Evening Settle20:57TRANSITIONacked-20:57Acknowledged: Evening settle check: current climate is in band (64.5°F, VPD 0.43 kPa, dew-point margin 6.5°F), equipment is stable in IDLE with vent/fog/misters off, and active plan already shifts to overnight humidity conservation before Sunday dry-ramp preconditioning. No tunable change needed. Resolved 20:57 MDT.
New forecast data21:40FORECASTacked-21:41Acknowledged: Forecast update does not materially differ from active plan iris-20260502-1958: Sunday peak temp remains ~78-79F, RH min 8% vs planned 6%, and solar/cloud pattern remains within the existing dry-ramp preconditioning posture. No tunable changes needed. Resolved 21:41 MDT.
New forecast data22:41FORECASTacked-22:42Acknowledged: Forecast update reviewed: temperature peak (78F) and severe dry-air pattern (RH 7-10%, outdoor VPD near 3 kPa) still match the active plan’s Sunday dry-ramp posture. Cloud cover/solar shifted lower than planned (solar peak now ~619 W/m2 vs ~811), which reduces heat-trap risk rather than requiring a more aggressive change. Existing 09:00 waypoint already pivots to engage/all 1.1/1.5, 20s gap, high VPD weighting, short sealed-vent duration, and fog_escalation near 0.2. No tunable change needed. Resolved 22:42 MDT.
New forecast data23:40FORECASTacked-23:41Acknowledged: Forecast update reviewed: Sunday remains close to the active plan's intent — same ~78F peak and very dry RH 7-10% midday, with lower/overcast solar than the plan's conservative dry-ramp assumption. Existing 06:30/09:00 waypoints already pivot to aggressive dry-day mist/fog preconditioning, so no tunable change is warranted. Resolved 23:41 MDT.

Validating previous cycle: iris-20260501-1956

Previous hypothesis: Overnight challenge is controlled heating through a 36F pre-dawn low without re-creating heater→vent oscillation or pushing dew-point margin below 5F. I am using gas-friendly heat staging, +4F cooling bias, conservative humidity/fog thresholds, and valid mister delay values to clear today’s repeated delay clamps. Saturday turns sharply clear and dry after 09:00, so the final waypoint preconditions for the 10:00-17:00 VPD ramp with aggressive mist/fog posture while keeping sealed-vent duration short. Result: [backfill] compliance unavailable over plan window 2026-05-02 12:02 → 2026-05-02 14:02 Score: 4/10

Hypothesis

Testing: Early VPD preconditioning plus VENTILATE-fog escalation: test whether fog_escalation_kpa 0.20-0.25 and 15s mist gaps before 09:00 reduce VPD-high stress below 3h without exceeding 0.5h dew-point risk or repeating late-day VPD-low overshoot. Expected outcome: Planner score >70, both-axis compliance >70%, VPD-high stress <3.0h, heat stress <4.0h, VPD-low stress <2.0h, dp_risk_hours ⇐0.5, cost near or below USD 6.

relax mist thresholds, widen hysteresis, and return to 45s gaps after solar decline

Parameter rationale

mister_engage_kpa1.8 → 1.05; VPD ramp begins by 09:00 and outdoor RH is below 20% by 10:00

start humidity correction before the steep ramp and keep VPD-high stress below 3.0h

mister_all_kpa2.4 → 1.4; solar 844-897 W/m2 and outdoor VPD 1.9-2.4 kPa during peak

bring all mister zones in before south/west desiccate; peak indoor VPD below 2.6 kPa

mister_pulse_gap_s60.0 → 15.0; clear dry peak from 10:00-17:00 with low condensation risk

increase evaporative cadence during the VPD ramp without extending sealed duration

fog_escalation_kpa0.3 → 0.2; post-PR-A VENTILATE fog is the correct tool for hot-dry stress; yesterday 0.30 underperformed

use fog earlier in VENTILATE and reduce VPD-high stress by at least 1h versus yesterday

mist_max_closed_vent_s180.0 → 150.0; yesterday heat stress reached 4.93h and solar overshot forecast

avoid heat trapping while still allowing short humidity pulses

vpd_hysteresis0.5 → 0.3; dry clear day with dp_risk_hours near zero

tighten recovery during solar peak while keeping dew-point risk under 0.5h

Hypothesis

Testing: Operational repair: floor mister_all_kpa to confirmed firmware executable values after alert 2711 without weakening engage threshold, mist gap, weighting, or fog escalation. Expected outcome: setpoint_unconfirmed for mister_all_kpa clears after the next dispatcher/confirmation pass; Saturday VPD-high stress remains under 3h if fog and mist cadence keep pace with the dry solar ramp.

Previous hypothesis: Saturday is a clear dry-solar stress day. Yesterday proved 0.30 fog escalation and 20s mist gaps were not enough when solar overshot; today I am preconditioning earlier, using VENTILATE fog more aggressively, and keeping sealed-vent windows short so humidity control does not become a heat trap. Result: 2026-05-02 closed at planner_score 59.5 with 56.3% both-band compliance. Temp compliance was 76.8% and VPD compliance 65.1%, so VPD remained the weaker axis, but the stress mix shifted entirely to over-humidification: heat/cold/VPD-high stress were 0.0h and VPD-low stress was 4.0h. The late-afternoon dry-shoulder extension achieved its core safety hypothesis (peak temp 81.2F, peak VPD 1.75 kPa, dp_risk_hours 0), but it overshot humidity and used very high mister water (489 gal) for only moderate compliance gain. Cost was USD 4.16, below the 7d avg USD 4.63, driven mostly by gas (USD 2.76) plus electric (USD 1.40); water metering for total gallons reported 0 despite mister_water_gal, so total water cost is unreliable for this day. Score: 6/10

New finding: Late-afternoon dry-shoulder extensions can cap VPD-high stress and avoid heat risk, but if VPD-high is already controlled they should relax earlier or widen hysteresis/gaps to avoid VPD-low stress and high mister-water use. → Added to Lessons Learned

Hypothesis

Testing: Late-afternoon dry-shoulder extension: keep executable aggressive mist/fog thresholds through 19:30 instead of relaxing at 16:30. Expected outcome: Reduce additional VPD-high stress after 16:30 by at least 0.5h versus the prior relaxation while keeping dp_risk_hours at 0 and avoiding heat trapping through 150s sealed-vent caps.

Previous hypothesis: Forecast update: the new 24h forecast keeps this afternoon clearer and drier than the active 16:30 relaxation assumed — outdoor RH stays 8-10% through 19:00 with solar still 690→323 W/m2 from 16:00-18:00. I am extending the aggressive VPD posture through the late solar shoulder while preserving the evening and Sunday waypoints. This follows the validated dry-solar lesson: fog_escalation near 0.20-0.25, executable all-zone threshold at 1.55, short mist gaps, and short sealed-vent duration. Result: [backfill] compliance unavailable over plan window 2026-05-03 01:59 → 2026-05-03 17:26 Score: 4/10

Hypothesis

Testing: Overnight humidity-conservation plus early Sunday dry-ramp preconditioning: widen mist thresholds overnight, then switch to aggressive fog/mist before VPD rises. Expected outcome: Overnight dp_risk_hours remains 0, cold stress stays near or below 1h, and Sunday VPD-high stress improves versus today’s 6.43h despite very dry outdoor air.

lower engage/all to 1.1/1.5, 20s gap, fog_escalation_kpa 0.22 once dry ramp begins

Parameter rationale

bias_cool2.0 → 3.5; overnight outdoor 48-63F with heaters likely against a 63F band

reduce heater overshoot venting and keep cold stress near or below 1h overnight

mister_pulse_gap_s45.0 → 60.0; current VPD 0.48 kPa and dew-point margin 7.0F; fog blocked overnight

avoid VPD-low overshoot and conserve water while humidity holds naturally

mister_engage_kpa1.6 → 1.1; Sunday RH falls to 6-10% with VPD 2.6-3.1 kPa after noon

start humidity correction before the 09:00-13:00 VPD ramp and reduce VPD-high stress vs today's 6.43h

fog_escalation_kpa0.6 → 0.22; post-PR-A fog is the high-leverage tool during VENTILATE and tomorrow remains very dry

use fog earlier in hot-dry ventilation windows while keeping dp_risk_hours at 0

mist_max_closed_vent_s240.0 → 180.0; dry/high-solar lesson says not to extend sealed heat-trap cycles

prevent heat trapping while allowing short humidity recovery cycles
