What
The sandbox is a restricted area where Claude Code runs commands. After a command finishes, the sandbox cleans up at a file path and records what it did. If recording that result fails, Claude Code now writes its own diagnostic message about it.
Why
The change is for troubleshooting. Claude Code otherwise behaves the same.
