Jun-te Kim 782c686969 Map fuel code 39 (electricity, any tariff) to standard electricity ... modelling_e2e properties with main fuel 39 failed at the price boundary (UnpricedFuelCode since #44fff767; previously mis-rated as non-electric → the ~14-SAP over-rating flagged in earlier review). Code 39 is SAP Table 12 "electricity, any tariff" (epc_codes.csv main_fuel 39 = "electricity, unspecified tariff"; spec footnote (j): defines an electric system, cost/CO2/PE = standard electricity). It was absent from API_FUEL_TO_TABLE_32, so to_table_32_code(39) was None → is_electric_fuel_code(39) False and pricing raised. Fix: map API_FUEL_TO_TABLE_32[39] = 30 (standard electricity) — the canonical place Khalim's fuel work added codes. One line makes classification, pricing, CO2/PE and the billing carrier all agree (39 → 30 → ELECTRICITY). Tests: to_table_32_code(39)==30, is_electric_fuel_code(39) True, price == standard electricity, and the billing carrier resolves to ELECTRICITY. 0 corpus impact (no lodged corpus cert uses 39); accuracy + mapper-corpus gates green.
