vk.flip_capture_failed: display buffer not registered for Vulkan flip (Dead Cells, Arkanoid)

[jackby03]

Symptoms

• Dead Cells (PPSA15552): vk.flip_capture_failed version=1 queue=dcb.graphics addr=0x102440000 found=False
• Arkanoid Eternal Battle (PPSA06328): Debug.Assert in ExecuteOrderedGuestFlipWait
• Both crash with Access Violation (0xC0000005)

Log evidence

[LOADER][WARN] vk.flip_capture_failed version=1 queue=dcb.graphics addr=0x0000000102440000 found=False initialized=False

Arkanoid stack trace:

at System.Diagnostics.Debug.Fail(...)
at VulkanVideoPresenter+Presenter.ExecuteOrderedGuestFlipWait(...)
at VulkanVideoPresenter+Presenter.Render(Double)

Assertion: An ordered wait-safe marker must execute after its flip capture.

Analysis

1. Game calls sceVideoOutRegisterBuffers with a pixel format
2. MapPixelFormatToGuestTextureFormat only supports RGB8 (fmt 56) and RGB10 (fmt 9)
3. If the game uses a different format, RegisterKnownDisplayBuffer skips registration
4. When SubmitFlip arrives, the image address isn't in _availableGuestImages or _guestImages
5. ExecuteOrderedGuestFlip fails silently (vk.flip_capture_failed)
6. ExecuteOrderedGuestFlipWait triggers Debug.Assert because capture was expected
