- Eyes render under a VK_EXT_fragment_density_map: full rate around each eye's forward direction, 2x2 then 4x4 pixel blocks towards the edges ([vr] foveation = off|low|medium|high, default off). XR_FB_foveation cannot help here: the runtime's maps only shape passes drawing into its swapchain, and the eyes reach it through a copy. - aurora-main/patches/dawn/aurora_fdm.inc: Dawn enables the extension only on request and for dynamic rendering, flags every render pipeline, and chains an immutable RG8 map into any pass whose first color attachment is a view bound to one (ABI: include/aurora/dawn_fdm_abi.h). - android/Build-QuestDawn.ps1 builds the pinned Dawn revision with those patches for arm64 (dawn-build CI flags, protobuf off) into a cached package; Build-Quest.ps1 links it (-StockDawn opts out) and AuroraDawnProvider.cmake enables the ABI from its manifest. - lib/gfx/foveation.hpp generates the maps (32 px per texel, densities 255/127/63); an eye is foveated only when single_pass_eyes draws it in one render pass. Menus never are. - Live level from the headset panel's VR tab and the launcher; the launch decides whether the device has maps. debug.wiicompiled.foveation and debug.wiicompiled.fdm for A/B. - Tests: Foveation cases in gx_fifo_tests, mkw_vr_config_tests.
