    "gotchas": [
      "Version: v0.19.6",
      "routing-mode (required): The release note names `hybrid` as the routing-mode value. The current Helm values docs list only empty, `native`, and `tunnel`; they do not document `hybrid`.",
      "routingMode (required): Helm value documented to enable native-routing or tunneling mode; allowed values are empty, `native`, and `tunnel`.",
      "Docs conflict: Current Cilium 1.20.3 Helm values docs do not list `hybrid` as an allowed `routingMode` value; current routing docs describe native routing and encapsulation, without hybrid. The v1.20.0-rc.1 release discussion says hybrid routing support was reverted.",
      "Docs conflict: No complete runnable `cilium` CLI invocation using `routing-mode: hybrid` found in official documentation at or after v0.19.6."
