+# ModelHub cloud build probe
+
+Minimal standard-library HTTP server to distinguish source retrieval, base-image
+and dependency-installation failures. Contains no account, password, token or
+adaptation code. It logs credential-related environment variable names only;
+values are never read into the log or HTTP response. It does not submit tasks.
