Runs the same requests your tools make when you click a server save — and reports what actually comes back instead of quietly falling back to local. Writes only to a scratch drawer called diag-check; your real drawers are never touched.
You've opened this as a local file. Browser security will fail most of these checks no matter what the server does. Upload this file to a shecreates.dev address first, then run it from there — that's the environment your tools live in.
