The whole of Horizon is in beta, so the channel that installs every build as soon as it is built is called Alpha; Stable keeps its name. The launcher's Settings, the update-channel command, the MCP tool, the release notes footer and the docs say Alpha. update_channel is saved as "alpha"; "nightly" and the old beta_builds switch still read as Alpha.
