    AffineKernelChoice: "tiled-causal" | "unfused"

    The read kernels of a composition's affine-quantized caches. tiled-causal is OptiQ's rule: a window through the N-tiled fused port while the cache's own mask is plain causal (where the port takes the configuration), every other read through the unfused port. unfused is mlx-lm's port for every read. --fused-sdpa on composes the first and off the second; unset, a per-layer scheme (--kv-quant config) composes tiled-causal and a uniform one unfused, which keeps each scheme's oracle parity.
