Finders have tried I_16x16, I_4x4, I_8x8, 4:2:2, 4:4:4, P-slice, field, monochrome, and multi-mb approaches — all crashes converge to the same family. Recent submissions (#108-#120) are just random trailing-data variants of the same PoC, showing finders are stuck in a loop. The only unexplored path that could yield a different dedup token is the chroma residual path (decode_chroma_residual instead of decode_luma_residual), but prior chroma attempts all failed to crash.
