Enum ExpertBacking 

pub enum ExpertBacking {
    Resident(Vec<ExpertWeights>),
    Stored {
        store: Arc<ExpertStore<GgufExpertSource>>,
        layouts: Vec<StoredExpertLayout>,
        layer: u32,
    },
}

How a layer’s routed experts are held. Resident is the original always-in-memory form (owned f32 or zero-copy mmap views). Stored holds only byte-range layouts; each use acquires the expert’s bytes from a bounded, lease-protected ferrox_core::expert_store::ExpertStore shared by every layer (one global byte budget), builds temporary WeightMatrix views over the leased buffer (WeightBytes::Shared, which pins the cache entry for the views’ lifetime), and drops them after the expert runs. Dequantized math over identical bytes is identical, so the two backings are bit-equivalent by construction – pinned by an integration test against the MoE fixture.
