Reproduce the issue on win32 with Windows Terminal and Claude Code 2.1.114, using /clear and then a previously accepted query. Start from the reported B:/~BUN/root/src/entrypoints/cli.js entry point and investigate the ENOENT cleanup and policy-related errors; done means /clear no longer leaves usage-policy errors affecting later queries.
