## FAQ

### What happens if I retry a request with the same key?

A retry using the same key will return the original receipt instead of dispatching the action again.

### Can the gateway prove that a remote effect actually happened?

No, the receipt signs request and response hashes rather than raw tool content, so it cannot prove a remote effect occurred.

### What is a 'delivery_uncertain' receipt?

This status means no trustworthy answer was returned; the debit is kept and the operator must manually reconcile with the downstream tool.
