This blog post series picks up where I left off in how AI agents revived my old PHP framework project.

In my previous post, I wrote about how a swarm of AI agents helped me revive a PHP framework I had abandoned years ago. That post was the origin story. This little series is the first real proof that the revival was worth it.

Because a framework on its own is just plumbing. What I really wanted to know was simpler and scarier: could I build a serious, production-grade feature on top of it without hating my life? Not another to-do list demo. The thing every app needs, nobody enjoys writing, and that ruins your week when you get it wrong.

Authentication.

So I built Polaris. It is the official identity module for Univeros, and this post is the tour. The four how-tos that follow get hands-on with each piece. Here I just want to show you the shape of the thing and why it is built the way it is.
