    Normative contract

    contract · L1 · accepted

    Every Matrix ACC form MUST read explicit C and publish distinct D. C's encoded relative selector MUST differ from zero-extended DstTile before allocation, and direct Tile calls MUST use different C/D TileIndex values. C MUST persist while D, reductions, and numeric status publish atomically.
