The stream wrapper takes a keepalive interval and enqueues a pre-encoded ping frame.\n\n**Details**\n\n- The bundled Bedrock proxy guidance document was updated to state the same requirement for third-party proxies.\n\n**Evidence**\n\n`emit your own \\`event: ping\\` during silent gaps`\n\n- Area: Proxy\n- Tier: You'll notice\n- Useful: 3\/5\n- Signal: 2\/5"}
