ShallGuard
Code got cheap. Trust did not.
ShallGuard is a tool for Rust projects. It keeps a written list of what the software must do. It connects each requirement to the code that makes it true and to the test that proves it. If a link breaks, the build fails.
The check needs no network and no language model. It gives the same result each time. A coding agent can write the code, but a person owns the requirements.
