main_heating_category=9 (warm-air systems, NOT heat pump) had no entry in _SECONDARY_HEATING_FRACTION_BY_CATEGORY, so a warm-air main with a lodged secondary raised UnmappedSapCode in _secondary_heating_fraction_for_category — the last calc_raise in the API sample (cert 0380-2197-2590-2996-2715: warm air mains gas code 506 + electric room-heater secondary). SAP 10.2 Table 11 (p.188): a gas/oil warm-air unit falls under "All gas, liquid and solid fuel systems" (0.10), and electric warm air under "Other electric systems" (also 0.10) — so 0.10 regardless of fuel. The warm-air efficiency (Table 4a code→eff: 506→0.70) and Table 4f fan energy were already wired; this was the only missing dispatch entry. 0380 now computes: SAP 78.1 vs lodged 77 (+1.1; the residual is per-cert fabric/PV, not the warm-air dispatch — a faithful 0380 worksheet isn't available, sim case 28 diverges at SAP 57 / code 502 / condensing unit). Eval: zero raises remain, computed 908→909; mean|err| 1.703→1.702. Regression green (2448 pass incl. golden 6035 + cohort); pyright net-zero (44=44).
