What's inside?

The main challenge

I'm focusing on secure failure handling: daemon crashes, camera failures, liveness timeouts, and ensuring errors never result in successful authentication.

🚧 Status: Pre-alpha, experimental, and not production-ready.

I'd appreciate feedback from the Linux community, especially on PAM architecture, security weaknesses, and testing priorities.

What failure cases would you test first?
