    "incantation": "When sharing a temporary tunnel to a local development server with access limited to specified email recipients, run `cf tunnels quick-start` with `--allowed-mail` and the origin URL. The option accepts email addresses or wildcard domains and may be repeated or comma-separated; use `cloudflared` 2026.9.2 or later for protected tunnels.",

      "Prerequisite: Protected Quick Tunnels require `cloudflared` 2026.9.2 or later.",
      "Prerequisite: The `cloudflared` command documents `--allowed-mail` as repeatable or comma-separated.",
      "Protected tunnels require `cloudflared` 2026.9.2 or later.",
      "For older or unrecognised `cloudflared` versions, cf reports an upgrade error."
