`CLAUDE.md` is context, not an enforced policy. Place it where Claude Code loads it, for yourself across projects or for one project, and check which files loaded with `/memory`. See [Claude Code memory](https://code.claude.com/docs/en/memory). Anything that must be enforced belongs in [permissions](https://code.claude.com/docs/en/permissions) or [hooks](https://code.claude.com/docs/en/hooks-guide).
