-# VK CTS validation: fury's a0 interpolation fix
-
-convoy: hq-cv-wr4iu (llvmpipe-rasterizer-validation)
-
-## summary
-
-fury's fix changes interpolation origin from framebuffer (0,0) to vertex 0
-position for numerical stability with triangles far from origin.
-
-**result: no regressions, no fixes detected. fix is safe from a CTS perspective.**
-
-## test results
-
-tested dEQP-VK categories focused on rasterization/interpolation.

-## notes
-
-- the fix is designed for numerical stability with triangles far from origin,
-  which the CTS may not explicitly stress.
-- identical results baseline vs fix suggests no functional regression.
-- the "not supported" counts are expected - lavapipe doesn't expose all
-  features (shader_tile_image, android external formats, high sample counts, etc).
