- Luigi Circuit Grand Prix start on a Quest 3, same-session A/B through the debug properties:
one render pass per eye saves 12% of eye GPU time at render_scale 0.8 and 8% at 1.3.
- Foveation is neutral at 0.8 (eyes are geometry and full-resolution tile-store bound) and saves
8/14/22% at Low/Medium/High at 1.3, so it stays off by default.

- 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. Docs: OPENXR.md, quest-port.md.

- Added eye_pass_plan.hpp: an eye keeps drawing in the render pass it has open across the frame's
GX copies (only the mono render performs them), skips passes a later clear of the whole color and
depth erases, and splits only for a clear of color alone or depth alone.
- render_stereo_eye follows that plan; the cockpit fallback is drawn inside the last pass instead of
a render pass of its own that loaded the eye back.
- The stencil is now cleared where the eye actually starts, so a cockpit mask drawn in an erased pass
can no longer punch holes in the HUD.
- [vr] single_pass_eyes (default on, live from F10) and debug.wiicompiled.eye_passes 0/1 on the Quest
switch back to one render pass per recorded pass for A/B timing.
- Each new plan shape is logged once ("Eye replay plan: ...").
- Tests: EyePassPlan cases in gx_fifo_tests; stereo_multiplayer_smoke and stereo_frame_worker_smoke
pass on D3D12.

The rule and its cost are not obvious from the code: the substitution is per
draw, so the merge test is too, and getting that wrong is worth 6 ms of GPU time
a frame in a race.

The Quest launcher's Settings > VR gains a Seat choice (cockpit or
custom, first_person_seat) and a Hand steering switch (hand_steering, off
by default like the runtime), which is only enabled in the first-person
cockpit because the wheel belongs to that seat. About credits heurazy for
the turning steering wheel and hand steering. The runtime side was already
shared with the Quest build.
OPENXR.md records what one Quest 3 race showed: the kart's own wheel
animated (228 draws a frame) with the race camera's view matching the
scene's exactly, but the driver's eye was never calibrated and the
fallback put the wheel centre about 13 cm above eye level. The Quest
declares no hand-tracking permission, so hands are the procedural gloves.

The panel was drawn into the eye images, so below a 1.00x OpenXR
resolution its 1440x1080 canvas was minified into a small eye region and
the text became hard to read. It is now submitted as a quad layer of its
own over the scene's projection or menu quad, which the compositor samples
directly at any render scale.
Each backend (D3D12, Windows Vulkan, Quest) makes the panel's swapchain
pair (plus two shared buffers on the Quest) the first time the panel
opens. While it is open, the frame hands Aurora one more stereo target
after the eyes, which the bridge fills with the panel texture or a
transparent image. The panel image follows the eyes' displayed/retained
pairing, so a cancelled frame never shows an unwritten panel. The quad
hangs where the pointer's hits are tested. Aurora leaves the panel out of
the eyes in layer mode, and a backend that cannot make the layer falls
back to drawing it into the eyes.
On the Quest, debug.wiicompiled.panel_layer 0 selects the old path at
run time. Measured there at a race start (render_scale 0.8), the layer
costs nothing while the panel is closed; while it is open, app GPU time is
10.5 ms against 9.7 ms drawn into the eyes, with unchanged frame rates.
The replay tests cover lazy creation, cancelled frames, closed and
unplaced panels, and render-first pacing on D3D12 and Windows Vulkan.

The native-registration scan only knew PPC_NATIVE_OVERRIDE, so every
GX_DEFERRED_OVERRIDE_VOID was missing from the index; the deferred form
registers `symbol` and posts the hand-written `symbol_gx`.
A Retro Rewind kit built from a translation without the Retro-WFC payload now
refuses to package instead of crashing on entering WFC, and on Android ImGui
keeps off SDL's cursor, which ART aborts on from a guest fiber's stack.
