PartitioningSpec	local
	Distribution within a rank (corresponds to local/single communicator).

Detailed Description

Hierarchical partitioning metadata for a data stream.

Describes how data flowing through a channel is partitioned at multiple levels of the system hierarchy. Each level corresponds to a communicator used to shuffle data at that level:

• inter_rank: Distribution across ranks, corresponding to the primary communicator (e.g., Context::comm()). Shuffle operations at this level move data between ranks.
• local: Distribution within a rank, corresponding to a single-rank communicator. Operations at this level repartition data locally without network communication.
