An echo tool grew a callback_url and lint had nothing to say about it — which is why the cassette gate has a second step that only asks whether the server's surface moved.
A cassette is a verbatim transcript of what a third-party server said, committed to your repository and fed to a model — so lint reads it for injection smells, and its rule packs are TOML on purpose.
