discontinued Copilot X never became a separate product line. GitHub announced it as a 2023 vision for chat, pull-request help, docs context, voice/CLI assistance, and broader AI workflows, but the surviving capabilities were folded into the current GitHub Copilot product and plans rather than a distinct Copilot X SKU.
