Enum PlanValidity 

pub enum PlanValidity {
    Valid,
    AllocationChanged,
    Stale,
}

Whether a held plan may serve a step, and if not, why not — one set of comparisons, so the “is it valid” and “is only the allocation different” questions cannot drift apart. DecodeSession::is_valid_for is a thin view over this.

Variants

Valid

Reuse the plan as-is.

AllocationChanged

Everything the plan bakes still matches except which KV allocation it is welded to. A guarded DecodeSession::rebind_kv may rescue it; without one, the plan MUST NOT be reused — that is GAP-014.

Stale

Something structural differs (shape, layer count, dtype, or the model itself). Rebuild.
