Struct TqHbOracleParams 

pub struct TqHbOracleParams {
    pub num_heads: u32,
    pub num_kv_heads: u32,
    pub head_dim: u32,
    pub kv_seq_len: u32,
    pub kv_capacity: u32,
    pub scale: f32,

}

Parameters for the HB TQ flash attention decode oracle.

Field-for-field mirror of crate::ops::flash_attn_vec_tq_hb::FlashAttnVecTqHbParams — kept independent so the oracle has zero dependency on Metal types.

Fields

num_heads: u32

num_kv_heads: u32

head_dim: u32

kv_seq_len: u32

kv_capacity: u32

scale: f32

mask_type: u32

sliding_window: u32

softcap: f32

Note: present in kernel params but never read in the kernel body. Oracle mirrors the kernel by NOT applying softcap. Tracked as F-0 finding: contractual drift vs flash_attn_vec.metal where softcap is also documented but unimplemented.

ring_start: u32

scale_factor_d512: f32

Only used when head_dim == 512. For D=256 set to any value.

codebook_bits: u32

Codebook bit-width: 5, 6, or 8.
