Manifest version: v3-ue-mobile-fps-budget.v1

The GA native mobile performance gate validates the Lilith Commons Atrium in a Shipping build on the required iOS and Android hardware classes:

Profile Platform Device Renderer Budget Observed sustained Observed p95
ios-iphone15pro-forwardplus-60 iOS iPhone 15 Pro Metal Forward+ >= 60 fps 63.7 fps 60.5 fps
ios-iphone13-forwardplus-30 iOS iPhone 13 Metal Forward+ >= 30 fps 35.2 fps 31.4 fps
android-pixel8pro-vulkan-forwardplus-60 Android Pixel 8 Pro Vulkan Forward+ >= 60 fps 64.1 fps 61.8 fps
android-pixel6-vulkan-forwardplus-30 Android Pixel 6 Vulkan Forward+ >= 30 fps 32.8 fps 30.6 fps

The iOS gate is anchored to IOS_ForwardPlus.json, IOS_ForwardPlus.json asset preset, and IOSDeviceProfiles.ini. The Android gate is anchored to Android_VulkanForwardPlus.json, Android_VulkanForwardPlus.json asset preset, ASTC cook flavor, and AndroidDeviceProfiles.ini.

The verifier fails closed when any required mobile device is missing, a cook profile or asset preset artifact is absent, CI is not green, the sample window is shorter than 30 minutes, the frame sample floor is not met, sustained FPS misses budget, p95 FPS misses budget, or average GPU frame time exceeds the frame budget.
