+///     raw-blob-fallback semantics across the golden TagConfig corpus BEFORE the parser is delegated to
+///     <c>TagConfigIntent.Parse</c>. The walker's FullName copy falls back to the raw blob whenever the
+///     input is not a JSON object carrying a string <c>FullName</c> (blank / non-object / malformed /
+///     absent / non-string). Whitespace + non-string-property values are returned verbatim (not trimmed).
+///     Must be green on the unmodified tree and stay green through the swap.
