BunATV: reconstructing Apple TV control protocols in TypeScript

BunATV reconstructs Apple TV control protocols as a Bun and TypeScript library with a companion CLI. It implements Companion pairing and remote input, MRP playback and state messages, and AirPlay transport layers, exposing messages close to their wire format. The author credits PyATV research and reports finding additional MRP messages through Ghidra analysis of Apple frameworks.
