+- The first branch first marks the `worker_id` as idle, updates the watermark, and enforces ordered checkpoint execution. It then checks the cache for pending checkpoints and assigns any found to the idle `worker_id`.
 - The second branch handles incoming `CheckpointData` from the `CheckpointReader`. It discards checkpoints with sequence numbers less than the `current_checkpoint_number`, assuming they have already been processed. It then invokes the optional `preprocess_hook` method (defined in the `Worker` trait) to allow for validation, preparation, or caching of checkpoint data. If the hook executes successfully and an idle worker is available, the checkpoint is sent for processing otherwise, it is added to the cache for later processing.
