+# listener (DNS-mocked, network-isolated sandbox, pre-flight check) can
+# call this helper to surface the attempted call.  Format matches the
+# Python / Node / PHP / Go siblings so the host-side HttpStub log-line
+# merger parses all five streams identically.  No-op when NYX_HTTP_LOG is
+# unset so the same harness still runs cleanly under modes that did not
+# spawn a stub.  Single-quoted Ruby string literals keep this helper free
+# of the literal hash-after-double-quote sequence that would terminate
