I really don’t agree with having anti-cheat (ac1). I deliberately chose to use Gleam Wisp and I know it’s a web framework, and I wanted to get familiar with its API. I wasn’t trying to rely on low-level HTTP libraries for the Codecrafters challenge. This restriction feels unnecessary - we’re not kids, and I know exactly what I’m doing.

Noted! Not something we intend to change at the moment - we might offer more application-layer challenges in the future that are better suited for testing out web frameworks.
