Unclear The finding doesn't say what the Coe() transform does to the messages, so its exact effect on stored data is unclear.
What
When Claude Code replaces the entire set of messages in a conversation, it now marks the conversation as remote-originated (via markConversationRemote) and runs the messages through an additional transform step before saving them, rather than storing the raw list as before.
Why
This helps Claude Code correctly track which conversations came from a remote source (such as a synced or delegated session), which matters for features that behave differently depending on where a conversation originated.
