Troupe is a distributed protocol construction library built on Zig's type system. Its core philosophy is using type determinism to counter communication uncertainty: protocols are modeled as fully deterministic state machines, correctness is guaranteed through compile-time verification, and all communication unreliability (latency, loss, reordering) is isolated behind replaceable channel layers. Ultimately, developers can construct complex multi-role protocols as if writing single-threaded programs, confident that they will execute as intended in any environment.
