services.py - place_order: validates against live menu, prices line items authoritatively from DB (modifier ids resolved server-side, not trusted from input), creates LNbits invoice, persists order + items. Order id := payment_hash for zero-metadata listener lookups. - mark_order_paid: idempotent paid -> [accepted if auto-accept] + stock decrement + queues a print job. - transition_order: explicit state-machine guard for accept/ready/ complete/cancel/refund. - quote_balance_required: pre-flight total for the webapp's multi-restaurant balance check (per the user's requirement to verify funds before opening any per-restaurant invoice). tasks.py - Single invoice listener filtered on extra.tag == 'restaurant', looks up order by payment_hash, delegates to mark_order_paid. Wrapped in try/except so one bad payment doesn't kill the loop.

The invoice listener is the *only* place where money-moves trigger

business logic. We keep it small and idempotent: filter by

extra.tag == 'restaurant', look up the order by payment_hash, and

hand off to services.mark_order_paid().
