The test now properly verifies that when sourceCodePreview is disabled: - console.log() output still appears in stdout (program runs normally) - The source code line containing 'console.log' does NOT appear in stderr (source code preview is truly disabled) This confirms that the error formatting doesn't show the source code, while the actual program execution and console.log output still work. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
