+# Publishes a new version of the Oxide CLI to the Windows Package Manager
+# Community Repository (microsoft/winget-pkgs).

+# This is a dist "custom publish job": it is invoked from release.yml, which
+# dist generates from the `publish-jobs` list in dist-workspace.toml. Don't
+# wire it up by hand-editing release.yml -- `dist plan` fails CI when that file
+# differs from what dist would generate.
+#
+# Requires a WINGET_TOKEN secret: a classic PAT with the `public_repo` scope
+# (the action does not support fine-grained tokens) on an account with write
+# access to the oxidecomputer/winget-pkgs fork.
