Struct CheckpointAckToken 

pub struct CheckpointAckToken(/* private fields */);

Handle the host returns to ack_checkpoint once the blob is durably installed (§12.3).

It is not a KernelInput (§12.3 rule 4): acking is runtime maintenance, it writes no record, and a crash between install and ack is recovered from the installed checkpoint anyway. Deriving it from the checkpoint’s own digest is what makes “ack a checkpoint that was never handed out” unrepresentable.
