- MQTT import_cost_total / export_revenue_total now anchor fixed-fee / tax-credit accrual at max(contract start, first recorded period), so standing charges for untracked pre-recording days are no longer folded into the running total. - Add energy.import_cost_today / energy.export_revenue_today (monetary, total_increasing) that reset at server-local midnight, for per-day cost aggregation in Home Assistant alongside the running totals. - ContractForm add-version mode prefills the contract's open version values, so only the fields that actually change need editing.
