Reflection

Validating previous cycle: iris-20260824-0017

Previous hypothesis: MIDNIGHT plan for Monday 2026-08-24. Sunday closed at legacy score/compliance 60.6, essentially equal to the 60.8 seven-day average. Temperature and VPD diagnostics were both weak at 49.6% and 48.8%; heat dominated at 10.86 h, followed by 9.26 h VPD-high and 1.43 h VPD-low, with 0 h cold. Dew safety held with an 8.1F minimum margin and 0 risk hours. Attributable/graded compliance and reliable utility/cost fields remain unavailable, so no cost or controller-attributable claim is made. The completed SUNSET plan iris-20260823-1947 is graded 1/10, exactly matching the deterministic anchor. Its 4.4 h window scored 31.9, with 40.0% temperature and 25.7% VPD compliance. Low-side outcomes were safe—0 h cold and VPD-low, only 0.03 h each heat and VPD-high—but the live-edge recovery and stable corridor hypothesis failed causally and at the endpoint. At replacement, the house was 72.9F and 1… Result: Window 08-26 00:16-06:02 MDT: safe in-corridor outcome at the boundary. VPD recovered 0.93 → 0.67 kPa through pre-dawn, pre-dawn VPD-low 0.40h (under 0.5h goal), heat 0h, cold 0h, dp_risk 0h, min dew margin 8.0F. Window score 52.0 (comp 52.0, temp 53.1 / VPD 43.1). Core mechanism (band-coupled live-edge recovery bridge) mostly did not materialize: 162/167 guardrail events held (97%), only 5 dispatched, 13/29 first-waypoint writes missed. House stayed safe only because held/clamped values were already near-corridor. Repeats iris-20260825-1944 signature (81% held). Third consecutive plan with the held-repair pattern. Score 3 consistent with anchor 2: outcome above anchor, mechanism mostly failed to deliver. Score: 3/10

New finding: Sticky vpd_high_moisture_guardrail now holds >95% of plan moisture writes when plans diverge from its active caps (engage ~0.80-0.81, all ~1.00-1.01, gap ~41, fog ~0.25). After 3 consecutive plans with 81-97% held rates, the fix is to write plan waypoints ALIGNED with the guardrail’s active caps during live VPD-high VENTILATE, rather than writing ideal band-coupled values and relying on the dispatcher to repair them. When VPD is above the high edge, the guardrail caps are the effective operating point; plan writes should match them to minimize held-repair cycles and let the plan’s unique value (timing, taper schedule, resource budget) actually reach the ESP32. → Added to Lessons Learned

Validating previous cycle: iris-20260826-0016

Previous hypothesis: MIDNIGHT plan for Wednesday 2026-08-26. Tuesday closed at partial score 56.4/54.0; the governing sunset window (19:58-00:16) is graded 3/10 vs anchor 1 — safe in-corridor outcome (0.01h stress, 12.9F dew, 129 gal, all measurable goals met to the boundary) but 66/80 moisture writes held by the sticky VPD-high guardrail, so the core band-coupled wet mechanism mostly did not materialize. House now 70.5F / 0.93 kPa (above target 0.764, just under the live high edge ~0.966) in VENT_COOL, dew margin 12.9F — a safe but live VPD-high state, and alert 10427 shows the recurring late-night VENTILATE VPD-high moisture-assist gap re-emerging at the boundary. This plan: (1) opens a short band-coupled live-edge recovery bridge now (engage ~vpd_high+0.05, all-zone ~+0… Result: Window 08-26 08:55-14:22 MDT: comp 59.7 (temp 57.3 / vpd 51.6) vs 7d avg 57.5; stress 1.38h (vpd-high 1.04, vpd-low 0.63, heat 0.0, cold 0.0, dp risk 0h, min dew 8.0F). The conservative humid-morning hold kept pre-10:30 vpd-low at 0.63h (goal <0.5h — modestly over; morning over-mist recurred at smaller magnitude than 08-25’s 2.27h). The 10:30 compliance-first flip (guardrail-aligned writes: engage +0.05, all +0.25, duty 25, fog 0.15-0.20, budget 300, precool 1.5F, lead 60) kept the 11:00-14:22 dry ramp (indoor VPD 1.06-1.32 vs 0.951 high edge, outdoor RH 47→29%) at ~1.04h graded vpd-high and produced 0h heat stress inside the window (heat stress 6.08h accrued 14:00-19:00, the successor plan’s window, physics-limited at 84-85F indoor vs 90F outdoor). Core mechanism delivered this time: guardrail audit shows iris-20260826-1407 successor matched 3/210/84 with only 3 held + 4 missed, versus 81-97% held rates on the three prior plans — the guardrail-alignment lesson (iris-20260826-0016) broke the held-repair streak. Cost/kwh fields null again (recurring data gap). Net: goals met or near-met; residual afternoon VPD-high severity is the structural exhaust-only-box limit, not a tuning failure. Score: 6/10

New finding: On clear hot-dry days following a saturated dawn, the 10:30 compliance-first flip with guardrail-aligned moisture writes (engage vpd_high+0.05, all-zone +0.25, duty 25%, fog 0.15-0.20, budget 300 gal, precool 1.5F, lead 60 min) limits the 11:00-15:00 indoor VPD-high to ~1h graded even when indoor VPD sits 1.06-1.32 kPa against a 0.951 high edge, and keeps heat stress out of the morning window; the residual afternoon miss is severity from the exhaust-only box, not duration from late engagement. → Added to Lessons Learned

Hypothesis

Testing: Guardrail-aligned waypoints: during live VPD-high VENTILATE, write plan moisture values AT the sticky vpd_high_moisture_guardrail’s active caps (engage ~0.81, all ~1.01, fog >= 0.20 materialization) instead of ideal band-coupled values — 3 consecutive plans had 81-97% of writes held; expect >80% materialization this window (vs 3-19% last night). Expected outcome: 11:00-17:00 MDT VPD-high stress under 3h (vs 6.9h on 08-25); heat stress under 6h with residual 90F+ accepted as physics-limited; 0h dew risk (floor 8-9F); pre-dawn VPD-low under 0.5h; full-day water under 300 gal; >80% of plan moisture writes materialize per guardrail audit.

Parameter rationale

mister_engage_kpa0.81 → 1.25; dry ramp 10:00-12:00 (solar 463-738 raw, RH 50->38%); east at 0.95 kPa vs live high edge 0.94 at 08:28; value = vpd_high+0.05 at ~1.20 10:30 band; dew 9.2F

S1 misting engages at the live high edge in the 11:00-17:00 VPD-high window instead of waiting for the +0.14 excess that blocked assist (alerts 10427/10428)

mister_all_kpa1.01 → 1.45; indoor VPD forecast 1.3-1.5 kPa vs diurnal high edge ~1.2-1.3 (yesterday same weather peaked 1.32 indoor); value = max(1.0, vpd_high+0.25) at ~1.20 band

all-zone S2 rotation available near the high edge, closing the VENTILATE VPD-high moisture-assist gap (87% no-assist window at 01:30)

fog_escalation_kpa0.25 → 0.15; fog window 07:00-17:00 open, dew 9.2F, RH <45% from 11:00; fog is 7x mister effectiveness; hold 0.35 through humid morning ramp, 0.20 at 10:30, 0.15 from noon

no pre-ramp fog burst before the dry ramp is confirmed; fog available for the 12:00-16:00 peak; VPD-high stress reduced from 6.9h (08-25) toward under 3h

mister_water_budget_gal150.0 → 300.0; water trending down (370->129 gal over 5 days); 08-25 closed 129 gal; afternoon peak needs full authority; 150-gal budget clamped writes last night (missed 00:15)

afternoon misting not budget-limited; full-day water stays under 300 gal

Reflection

Validating previous cycle: iris-20260826-0016

Result: Scoped governed window: compliance 60.7%, temp 57.9%, VPD 47.7%; heat 5.94h, VPD-high 3.95h, VPD-low 4.52h, cold 0h. The extended hot/dry posture limited but did not prevent heat/VPD-high stress; later humidity overshot low-side VPD. Daily 2026-08-26 score was 56.6 with heat dominant at 8.76h, VPD-high 5.59h, VPD-low 3.60h, no dew-risk hours. Outcome was safe but materialization was dirty: repeated VPD-high guardrail holds/clamps and missed writes mean the requested mechanism did not cleanly land. Grade 4/10 preserves the prior anchor-aligned assessment rather than over-crediting aggregate recovery. Score: 4/10

Hypothesis

Testing: Delaying the evening moisture taper from 17:00 to 21:00 after observed cloud clearing: does holding the compliance-first hot-dry posture an extra 4h reduce 15:00-19:00 VPD-high stress versus the original taper schedule, with no VPD-low or dew regression after 21:00? Expected outcome: East/west VPD at or below ~1.0 kPa by 19:00 (vs live 1.21-1.22 vs 0.94 high edge); no new vpd_low stress in the 14:10-21:00 window; dp_risk 0h; full-day water under 300 gal.
