some more after reading the source:

- JWT needs to be validated, as it is, your implementation[1] happily accepts anything, you can impersonate anyone you want. I'd argue that it's a bad default choice too [2]

- baking-in resend.com as email provider is unlikely to be useful for most people

- x-forwarded-for [3] is only added by proxy servers, and will often not be present. This means you'll be applying a shared rate limit to most of your users

- the 'ai' helper is missing from the code. If this is vibe-coded, having tests for the examples will help keep it cohesive

Sorry if this is a lot, I hope it can help.
