What issue are you seeing?

I'm setting up a new application as the solo developer. I instructed Codex to hard code my email address as the super admin with access to the admin portal—essentially a God view of all users. Later, it spelled out my email address as "matt@gist.si" instead of "matt@gist.is" When I asked where it got that, it claimed it was just a typo, but it worries me!

Maybe I entered it wrong? Maybe i introduced the typo? Totally possible!

I've never seen Codex make a typo before. Given the high stakes involved in getting this right, I'm very worried that the wrong email is in fact hard-coded in the system as the only admin and that this is going to fuck me later.

What steps can reproduce the bug?

What is the expected behavior?

Codex either spells my email correctly or identifies that the misspelled email was saved in the system
