Khalim Conn-Kowlessar	8ee877e44c	docs: handover update — +2.5 SAP cluster is heterogeneous, not a shared cascade gap ... Probed all three variants (electric 3, oil 1, solid fuel 2) in this thread. Each has a different driver despite the matching magnitude: - electric 3: §9 useful-demand calc for ctrl=3 storage heaters - oil 1: HW efficiency for Table 4b oil boiler (cascade 86% vs ws ~65%) - solid fuel 2: HW kWh lodged in different line ref (re-probe needed) Tested combined-R hypothesis (effective_R = (1-frac)·R_main + frac·R_sec per SAP 10.2 §9b) — the cascade currently DOES NOT pass secondary_fraction to mean_internal_temperature_monthly, so effective_R = R_main. Monkey- patching to inject combined R REGRESSES electric 3 (+2.55 → +3.17) because raising R lowers cascade demand — opposite of needed direction. Recommends taking the three variants as separate per-variant slices. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>	2026-05-31 19:20:43 +00:00
Khalim Conn-Kowlessar	c389645bfa	docs: handover post S0380.138..140 (off-peak tariff cascade + §4 cylinder storage loss) ... Three-slice handover covering: - S0380.138: per-tariff Table 32 low-rate dispatch - S0380.139: _is_off_peak_meter canonical normalization - S0380.140: §4 (56)m cylinder storage loss (extractor + cascade) Ranks next-slice candidates (top: +2.5 SAP cluster across electric 3, oil 1, solid fuel 2 — likely shared Table 9 MIT bug).
