Struct SpecTail 

pub struct SpecTail<'a> {
    pub lm: GraphW<'a>,
    pub lm_rows: usize,
    pub final_norm: &'a [f32],
    pub logits_out: &'a mut Vec<f32>,
}

Speculative-verify tail for the batched graph: fold final-norm + lm_head over every batch position and read all k logit rows back; the batch also snapshots the GDN state per position for gdn_spec_restore.

Fields

lm: GraphW<'a>

lm_rows: usize

final_norm: &'a [f32]

logits_out: &'a mut Vec<f32>
