> Radicle’s predefined COB types are stored under the refs/cobs hierarchy. These are associated with unique namespaces, such as xyz.radicle.issue and xyz.radicle.patch, to prevent naming collisions.

This looks like an interesting approach. I have question, to avoid copy a large .git project, we have partial cloning and cloning depth. If `cobs` grows too large, how can we partially clone it? Like select issues by time range?

The COB types are located in the Stored Copy, you would still be able to partial clone the working copy repo without the issues and patches, with your current git commands. There is a better explainer here: https://docs.radicle.xyz/guides/protocol#storage-layout
