## FAQ

### Does PayPilot automatically send emails?

No, it does not send emails unless sending is explicitly switched on, a person has approved the message, and the recipient is on the allowlist.

### How does the system decide on a retry strategy?

The strategy is determined by a deterministic rules table that maps failure codes to specific actions and retry cadences, rather than using an LLM for policy decisions.

### Can it handle Stripe webhooks?

Yes, it can accept real Stripe invoice.payment_failed events and verify them using the Stripe-Signature header.

### What happens if a failure code is not recognized?

If a code is not in the table, it fires a row named 'default' and the decision receipt indicates it fell through rather than matched.
