Unclear The finding does not say which messages the new test excludes or what a reader would notice.
What
Claude Code saves each conversation as a chain of messages, where each message points back to the one before it. When a group of messages is added to that chain, Claude Code picks an earlier message to attach it to. A new internal test now rules some messages out as that attachment point.
Why
This changes where added messages are hooked into a saved conversation.
