docs: handover post S0380.153..155
Session landed three spec-clean slices closing four major residuals:
- S0380.153 (Table 3 middle row for solid-fuel boilers): SF3 EXACT all
4 metrics (+0.30 → -0.0000). Found the rule that solid-fuel boilers
don't ship with dual programmers per §9.2.4.
- S0380.154 (§12.4.4 back-boiler summer-immersion): SF2 SAP+cost
EXACT (+1.86 → -0.0000 SAP; -£42.84 → -£0.00 cost). Implemented HW
fuel kWh split + monthly blend across cost / CO2 / PE / standing.
- S0380.155 (Table 4a HP water-column dispatch): gshp closed ±0.02
SAP (+0.94 → -0.0178). HW kWh 841 → 1138 matches worksheet exactly.
Σ |ΔSAP_c| 14.5 (session start of S0380.150) → 2.7 = 81% reduction
across 6 slices, two sessions.
Handover doc captures:
- Per-line discipline (walk worksheet before forming hypothesis)
- Elmhurst-vs-spec divergences to defer (lighting-PE +48.66 cluster
uses Table 12 annual factor; spec Table 12d mandates monthly)
- Ranked open fronts (electric 5 R=0.20 storage MIT, electric 2
warm-air HP HW, deferred lighting-PE cluster)
