Khalim Conn-Kowlessar 75ba5dd744 docs(modelling): ADR-0014 amendment — cross-stage billing + Modelling post-package bills ... Records the /grill-with-docs design for the Modelling Bill-Derivation slice: Bill Derivation is cross-stage (relocate Bill/EnergyBreakdown/BillDerivation/ sap_fuel to a neutral domain/billing/); Modelling bills the fully-overlaid post-package SapResult (so fuel-switch measures price at the new fuel for free), diffing against the baseline at the same FuelRates snapshot; the post-package and baseline SapResults are captured from scores the optimiser/orchestrator already compute (Score.sap_result), so no second calculate; FuelRatesRepository is constructor-injected into ModellingOrchestrator mirroring Baseline; plan-level columns this slice, per-measure telescoping bill cascade next (energy_savings is vestigial, left NULL).
