Captures a /grill-with-docs session resolving how BillDerivation gets the
fuel each end use burns, and what Rebaselining actually is.
- ADR-0014 amendment: per-end-use fuel is a calculator OUTPUT (resolved
Table-32 codes on SapResult: main-1/main-2/secondary/HW + pv_exported_kwh);
the adapter is a pure SapResult->EnergyBreakdown map. Corrects stale §3
(is_gas_code... -> sap_fuel.sap_code_to_fuel). Adds COOLING section.
Interim, pending ADR-0015.
- ADR-0013 amendment: the calculator is the SCORING ENGINE within
Rebaselining (assemble the Effective EPC picture, then score), not the
whole of it; the Rebaseliner exposes its SapResult so the orchestrator
composes Effective Performance AND the Bill from one scoring.
- ADR-0015 (new): mappers own cert normalization; EpcPropertyData becomes a
strict type. Explains why fuel resolution sits in the calculator today.
- CONTEXT.md: Effective EPC = the assembled picture; Rebaselining = assemble
(overrides / neighbour-estimation / old-schema remap) then score.
- EpcPropertyData docstring points at ADR-0015.
