claude-code - 💡(How to fix) Fix [BUG] Rewind broken in Claude Desktop 1.11187.4 — "rewind target not on CLI's active chain"

Preflight Checklist

• I have searched existing issues and this hasn't been reported yet
• This is a single bug report (please file separate reports for different bugs)
• I am using the latest version of Claude Code

What's Wrong?

When I try to rewind (double-press Esc or click a checkpoint in the timeline), Claude Desktop shows "Couldn't rewind — That point in the conversation couldn't be found." The rewind fails silently and the checkpoint is discarded. This happens on every session, every checkpoint attempt.

The error chain:

1. Desktop UI sends a checkpoint message UUID to the CLI
2. CLI responds: "No message found with message.uuid of: <uuid>"
3. Desktop logs: "Clearing stale pendingRewindTo ... — rewind target not on CLI's active chain"
4. Desktop shows the "Couldn't rewind" error to the user

What Should Happen?

Rewind should fork the session at the selected checkpoint and resume the conversation from that point.

Additional Information

This is a Desktop bug, not a CLI bug. The Desktop-to-CLI coordination protocol for rewind appears broken in 1.11187.4. The same bug reproduces with CLI 2.1.165 and 2.1.169 — the issue follows the Desktop version.
