cto-review

The code is intended as a test runner, but it executes locally sourced CONTEXT.md content as shell and Python code. That creates a significant trust-boundary risk if CONTEXT.md can be modified by an attacker or package tampering. Input values are appropriately shell-quoted, and no explicit network access, secret harvesting, persistence, destructive file operations, or reverse shell is present. The supplied fragment also contains a syntax error in fixture t13, preventing normal execution.
