Issues

• scene: GbmSurfaceSource hands back a surface that segfaults on first use, on any display-only node

• present: ScanoutBackend negotiates a modifier set, then hands it to a producer that ignores it

• scene: ~LayerScene documents the armed-flip hazard but never checks it

• planes: PlaneCapabilities::cursor_max_w/h are never assigned, so the allocator's cursor-size guard is dead

• select_plane rejects a cursor plane over channel order, spending an overlay on Tegra

• input: test_cursor_source silently skips on vkms, whose minimum framebuffer is 10x10 and whose fixture is 4x4

• examples: no rank array contains VIRTUAL, so every example finds no display on vkms or in a VM

• planes: supports_scaling is true for every plane on every atomic driver, so the matcher's scaling edge is dead
