Original GitHub issue: https://github.com/deepseek-ai/DeepEP/issues/694

CE is only used for engram communication, and in the all_gather

Any plans on sharing it in the future?

@YidaWeng commented on GitHub (Oct 1, 2026):

V2.5 publishes CP/DP collectives through BucketBuffer (see README "Bucket collectives" and the BucketBuffer API section: batched all_gather / reduce_scatter / all_reduce).

So the earlier gap where CP was mentioned but not shipped is largely addressed for the bucket path. Engram/PP remain experimental; if "CP" here meant something beyond bucket collectives, it would help to say which API was expected.
