Error message

Source and target Paperclip configs are the same. Choose different --from/--to values.

What it means

Self-reseed guard in worktree reseed: the resolved source and target endpoints share one config path, so the reseed would read from and overwrite the same instance; distinct --from/--to values are required.

Solutions

1. Choose different --from/--to values pointing at distinct Paperclip instances.
