- ContinuousAggregates migration: consumption_daily/monthly/yearly in Europe/Berlin buckets via migrationBuilder.Sql(..., suppressTransaction: true), with refresh policies (end_offset >= 1 bucket; current bucket covered by real-time aggregation). - TariffResolver (Core): time-ranged price resolution, scope precedence meter > type > global. - CostService: Dapper-aggregated monthly consumption × resolved unit price (+base, -feed-in), month-dominant pricing; category rollups over member meters + meterless manual costs. - Tests: water cost reconciles to the sheet's Kosten column, Wasser category rollup (Dez=70€), monthly CAgg refresh matches base, TariffResolver unit tests. 91 tests green (56 Core + 35 integration).
