2026-10-01: Carried-state FP32 conv verify (gdn_carry_conv_f32): the twin of causal_conv1d_update_l2norm_f32_strided for all num_tokens positions of n_seq sequences, with gdn_carry_conv’s pending-row fold and stash. Sequence b’s window is at conv_state + b * dim * d_conv floats; row b * num_tokens + t reads new_input at input_stride and writes the FP32 output at output_stride. lazy must match the verify kernel of the same run.
