MainFuelType had no individual wood-logs member — only "biomass (community)" — so the LLM classifier funnelled "Solid Fuel: Wood Logs" into the community fuel, inventing a community heat network the dwelling isn't on (and mislabelling the connection). main_fuel had no deterministic guard at all, so nothing caught it. Verified against domain/sap10_calculator/docs/specs: RdSAP 10 Specification Table 32 lists "wood logs" as a solid fuel (code 20, 0.028 kgCO2e/kWh); the calculator's input scheme (the gov EPC API fuel enum) codes it 6 -> Table 32 20 (sap_efficiencies._API_TO_TABLE32), and water_heating_overlay already pins the same fuel to 6. So _FUEL_CODES["wood logs"] = 6 is confirmed, not guessed. Adds MainFuelType.WOOD_LOGS + the _FUEL_CODES entry, a main_fuel_guard mirroring water_heating_guard (claims the "wood log" token; dual fuel keeps its own member since it has no "wood log" substring), and wires main_fuel through a GuardedColumnClassifier so the live path is deterministic. Applied the scoped backfill to portfolio 796 (Hyde): 21 rows off "biomass (community)" -> "wood logs". property_overrides (TEXT) only; the classifier-cache pgEnum member is deferred to the FE Drizzle migration.
