What
Rewinding moves a conversation back to an earlier point and removes the messages after it. Some of those messages can be REPL tool calls, which are requests from Claude to run code in a live interpreter. Such a call can leave events waiting in a queue to be checked later. When a rewind removes the call, Claude Code now discards those waiting events and notes that a rewind removed the REPL call they came from.
Why
After a rewind, Claude no longer receives events from calls that are no longer part of the conversation.
