- German-dialect scalar parsers in Core (GermanNumber/Money/Date, ValueCell): decimal comma, thousands dot, unit suffixes, € currency, both date shapes. - Declarative MappingProfile + RowClassifier (skip summary/blank/all-zero rows) + CsvImporter (CsvHelper) staging readings/events/manual-costs, with auto swap detection on register decreases and month-end anchoring for interleaved oil dates. - Four built-in ReferenceProfiles (Strom/Wasser/Heizöl/Kosten). - ImportService: commit as revertible import_batch + wholesale consumption recompute per affected meter (NormalizationService/MeterConfigFactory), revert by batch. - Reconciliation tests: all 4 CSVs match the sheet's own columns within tolerance (electricity 5 meters + Netz Einsparung, water swap→12, oil tank incl. deliveries + burner hours, cost category totals). Commit/revert round-trip verified on Timescale. 69 tests green (53 Core + 16 integration). Known follow-up (polish): historical imports can contend with the 30-day compression policy's background job; tests pause it. Consider retry-on-deadlock or deferred compression for large historical imports in production. Claude-Session: https://claude.ai/code/session_01WujdMtMJPbxDpDnMeK22rr
