Read-only Wave collections exception briefing. It reads a chosen invoice status bucket and asks the AI summarizer for exception-handling priorities: missing customer email, additional-recipient needs, unusual customer context, and largest or oldest receivables. Assume Wave native invoice reminders cover routine reminders. This recipe does not send invoice emails, mark invoices sent, record payments, update customers, or call arbitrary GraphQL.

Exception handler for Wave invoice reminders. Use this only when Wave's native invoice reminder automation is insufficient: the invoice customer has no primary email and the owner supplies an exception recipient, the reminder needs an additional recipient, or the owner provides a specific exception note. The recipe re-reads the business and invoice live from Wave, confirms the invoice still has an amount due, sends exactly one attended Wave invoice email, links the invoice to the customer, and seeds data.shared exception-watch state so wave-invoice-reminder-exception-watcher can close the loop when Wave shows the invoice paid or resolved. It never creates invoices, edits invoices, records payments, changes customers, deletes records, or calls arbitrary GraphQL.
