Struct Glm5NextTextSkeleton 

pub struct Glm5NextTextSkeleton {
    pub hidden_size: usize,
    pub hc_mult: usize,
    pub layers: Vec<SkeletonLayer>,
    pub mtp: Option<SkeletonLayer>,
}

Fields

hidden_size: usize

hc_mult: usize

layers: Vec<SkeletonLayer>

Text stack, indices 0..=44. Length is num_hidden_layers and never includes MTP.

mtp: Option<SkeletonLayer>

Layer 45. Held separately so every “iterate the text stack” loop keeps meaning what it says — the same discipline ModelConfig::mtp_layer_types established in Slice 8.

Implementations

impl Glm5NextTextSkeleton

pub fn from_config(cfg: &ModelConfig) -> Result<Self>

Derive the topology from a parsed config. Every kind is read, never defaulted: an unexpected LayerType is a hard error, because a sparse layer silently bound as dense attends the whole cache and produces plausible output.

pub fn all_layers(&self) -> Vec<SkeletonLayer>

Text stack plus the MTP layer, in checkpoint index order.

pub fn structural_tensors(&self, l: &SkeletonLayer) -> Vec<String>

The structural (non-MLP, non-MoE) tensors this layer needs, fully qualified.

pub fn structural_tensor_set(&self) -> BTreeSet<String>

Every structural tensor the whole skeleton needs, including the three non-layer ones.

pub fn residual_plan(&self, l: &SkeletonLayer) -> Vec<ResidualStep>

The residual/norm/mHC wiring for one layer, in execution order.

The MTP layer has no hyper-connection, so its residual path is the ordinary x = x + sublayer(norm(x)) shape and the mHC steps drop out entirely.

pub fn final_plan(&self) -> [FinalStep; 3]

What runs after the last text layer.

pub fn state_plan(&self) -> BTreeMap<usize, StateKind>

Per-layer cache requirement. Admission needs every kind satisfied at once.

pub fn kda_state_layers(&self) -> Vec<usize>

Layers whose recurrent state must be carried between steps.

pub fn kv_cache_layers(&self) -> Vec<usize>

Layers that consume paged KV blocks.

pub fn state_budget(&self, cfg: &ModelConfig, num_spec: usize) -> StateBudget

The per-sequence state contract, from the config’s real geometry.

🪤 kda_recurrent is fp32 and not negotiable: HF casts the recurrent state to float32 and vLLM hardcodes kda_state_dtype, so --ssm-h-dtype f16 is unavailable. Sizing it as bf16 halves the number and is wrong.

pub fn account(&self, available: &BTreeSet<String>) -> StructuralAccounting

Account the skeleton’s structural contract against a checkpoint’s tensor names.

available is the FULL name list; MLP/MoE and vision names are expected to be present and are reported as deferred, not as errors — this slice does not bind them. Anything structural that is missing, and any non-MLP text tensor the skeleton did not ask for, is a hard failure. Zero unknown, zero silent skips.
