The host can now inject coop_hook.dll into a running game and forward controller state to it over shared memory, so the game reads the host's (eventually the guest's) input and nothing else. - hook/: coop_hook.dll. DllMain spawns a worker that opens the shared-memory channel (named by the game's pid) and installs SafetyHook inline hooks on XInputGetState/GetStateEx/GetCapabilities/SetState. Detours synthesize state from shared memory; unmanaged slots report disconnected, hiding physical pads. - host/: process picker (Toolhelp32), CreateRemoteThread(LoadLibraryW) injector with an IsWow64Process2 bitness guard, IPC server publishing pads each frame, and an ImGui Injection panel wiring it together. - tests/: hook_selftest exercises the IPC seqlock + hook detours in-process (no game/controller needed); passes. Build: SafetyHook wired in (COOP_BUILD_HOOK=ON), Zydis via FetchContent. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
