Struct HcSiteWeights 

pub struct HcSiteWeights {
    pub hc_fn: DevicePtr,
    pub hc_base: DevicePtr,
    pub hc_scale: DevicePtr,
    pub lowrank: Option<HcLowRank>,
}

Per-block Manifold-Constrained Hyper-Connection (mHC) parameters for one site (attention or FFN). All buffers are float32 device pointers, matching the checkpoint dtype. See ops::hc_pre / ops::hc_post.

Fields

hc_fn: DevicePtr

Mix projection fn: [mix_hc, hc_mult*hidden] f32, where mix_hc = (2 + hc_mult) * hc_mult.

hc_base: DevicePtr

Mix bias base: [mix_hc] f32.

hc_scale: DevicePtr

Mix scale: [3] f32 (pre / post / comb scalars).

lowrank: Option<HcLowRank>

Qwen low-rank variant. Some => dispatch the low-rank kernels and IGNORE hc_fn/hc_base/hc_scale (which are NULL in that case).
