ReadonlyfetchThe write happens in the graph (ring) or outside it after the step (concat).
ReadonlyinputsClosure inputs this cache feeds, and closure outputs it returns.
ReadonlykeyGraph-shape signature (cache kind, quantization); offsets and capacities are array values or shapeless dimensions and stay out of it.
ReadonlyoutputsThe traced stand-in over this slot's inputs; ropeOffset is the int32 RoPE position input.
One cache's slot in a compiled decode closure. Plain data: it captures no cache, so a closure built once serves every later step and generation.
