Struct KdaSeqState 

pub struct KdaSeqState {
    pub conv: DevicePtr,
    pub recurrent: DevicePtr,
}

2026-09-25: The per-sequence state a KDA layer carries. The kernels update both buffers in place.

The conv buffer holds conv_kernel slots per channel. The conv kernels shift the window left and write the new input into the last slot before convolving, so slot 0 is shifted out unread. A state kept as conv_kernel - 1 slots (the golden generators’ layout) maps to slots 1..conv_kernel here, before the shift.

Fields

conv: DevicePtr

2026-09-25: [conv_dim, conv_kernel] FP32.

recurrent: DevicePtr

2026-09-25: [heads, head_dim, head_dim] FP32, K-major (S[k * head_dim + v]).
