Transformers Beyond Reality: Redux ended its first frames with Unreal's "Shader compilation failures are Fatal." With Lepton's Fossilize layer loaded every graphics pipeline failed with VK_ERROR_OUT_OF_HOST_MEMORY, even a constant-colour one; the pipeline cache, the app's CPU allocator and Valve's FDM/RPO layers were ruled out on the device. Without Fossilize a few multiview vertex shaders still fail in Turnip. - adapter.vk_no_fossilize: the shim removes VK_LAYER_fossilize from GraphicsEnv's debug layer list when the engine loads it (library constructor, same GraphicsEnv calls as zinkfix) - adapter.vk_pipeline_fallback: a refused graphics pipeline is created again with a blank fragment shader, then blank vertex + fragment shaders - catalog entry (status unknown, headless only), triage vulkan-pipeline-refused, PLAYBOOK, DEVICE_NOTES Headless on the dev Frame: RUNNING after 78 s at 72 fps (was: exit within 21 s). Headset check pending.
