Struct K3CpuFallbackState 

pub struct K3CpuFallbackState {
    pub cache: LayerCache,
    pub device_kda: Option<KdaDeviceState>,
    pub device_mla: Option<MlaDeviceKv>,
}

2026-09-25: Mixer state owned by one sequence; K3BoundLayer::release_state frees its device copies.

Fields

cache: LayerCache

device_kda: Option<KdaDeviceState>

2026-09-25: Once present, this is the current KDA state and cache holds only what it was seeded from.

device_mla: Option<MlaDeviceKv>

2026-09-25: Once present, this is the current MLA KV and cache holds only what it was seeded from.
