Host helper register_vk_layer/unregister_vk_layer registers coop_vk_layer's manifest as a per-user (HKCU, no admin) implicit Vulkan layer and writes the scoping file (%TEMP%\coop_vk_target.txt) naming the target game's exe, so the layer captures only that game and stays inert for every other Vulkan app. The Injection panel gains an opt-in "Set up Vulkan layer" checkbox (next to Auto re-attach, which the too-late banner points at); it registers on tick, unregisters on untick, and the panel destructor unregisters on host exit so no stale registration is left behind. Verified live: a registry-registered layer is loaded by the loader for a fresh vk launch (no env vars) and the scoping matches (active=1), then cleans up.

// Host-side setup for the opt-in Vulkan capture layer (coop_vk_layer). Registering it as a

// per-user implicit Vulkan layer makes the Vulkan loader insert it at vkCreateInstance -- so it's

// in the chain before a game (that caches its present pointer at init) can resolve

// vkQueuePresentKHR, the reliable early-presence path the inject-after-launch hook can't get.
