Axiom Assume Isolated
This is a Swift concurrency utility that lets you synchronously access actor-isolated state when you're certain you're already on the right isolation domain. It's designed for situations where you know you're on MainActor but Swift's type system can't prove it, like legacy delegate callbacks documented to run on main thread or performance-critical paths where you want to avoid the overhead of an async hop. The 948 GitHub stars and passing security audits suggest it's a trusted tool in the Swift community. Just be honest with yourself about whether you actually know the isolation context, because if you're wrong, you'll get runtime crashes instead of compile-time safety.
