A customer with open ISSUED invoices changed fiscal status at ANAF or the trade registry: became inactive (art. 92 CPF) or was reactivated, was struck off or dissolved, entered insolvency, registered or deregistered for VAT, or entered or left TVA la încasare. Checked daily; the first observation of a contact is a baseline and emits nothing. Idempotent: id = evt_fsc_<contactId>_<kind>_<date>, where kind and date are those of the first entry in changes.
