Claude Code's configuration settings merge lists rather than overriding them, meaning that deleting an entry from one settings file does not remove it from another. To effectively stop a permission, users must use a 'deny' rule or edit the file that originally added the permission. The tool's settings precedence is complex, with environment variables and specific security-sensitive keys breaking the standard merge rules, making it difficult to diagnose issues without using the `/status` command to see which files were loaded.
