Struct ZNegArgs 

pub struct ZNegArgs<'a> {
    pub cap: &'a [f32],
    pub n_cap_p: usize,
    pub rope_img: (&'a [f32], &'a [f32]),
    pub rope_joint: (&'a [f32], &'a [f32]),
}

The negative (unconditional) item of a CFG pair: its own refined caption, padded caption length and joint RoPE table (the image ids sit at axis-0 position L_p+1, so both tables depend on the item’s L_p).

Fields

cap: &'a [f32]

[n_cap_p, hidden], context-refined.

n_cap_p: usize

rope_img: (&'a [f32], &'a [f32])

[n_img_p · hd/2] cos, sin (noise refiner) of this item.

rope_joint: (&'a [f32], &'a [f32])

[(n_img_p + n_cap_p) · hd/2] cos, sin, rows [img, cap].
