Infrastructure-free normalization engine in Core dispatching on MeterMode: - Cumulative/Generation counters: register deltas, first-reading baseline (Haus 411, Auto 3755), meter swaps (water …861→2 reconciles to 12 via boundary registers OR an explicit amount override), counter resets, anomaly-guarded decreases. - RuntimeCounter: Δhours × rate (fixed/empirical). - ConsumableBalance: tank level-Δ + deliveries → consumption, cm→litre calibration; delivery-only rows before the first dipstick emit nothing. - DirectDelta, and Virtual meters via a small safe arithmetic evaluator (Netz Einsparung = Haus − Netz, Eigenverbrauch = Erzeugung − Einsparung) — data-driven, not hardcoded. - DatabaseSeeder: default energy types, cost categories, base settings (idempotent). 24 Core unit tests + 4 integration tests green.
