+
+# Manual Aminet upload. Triggered by hand from the Actions tab (or
+# `gh workflow run`) when you need to push an existing GitHub Release's
+# artefacts to Aminet -- typically because the automated upload in
+# release.yml failed (FTP hiccup, Aminet maintenance, anything else
+# transient) and you want to retry without re-tagging.
+#
+# The workflow downloads the versioned lha + readme from the named
+# GitHub Release, renames them to the unversioned form Aminet expects,
+# and runs the same aminet-release-action that release.yml uses.
+#
+# Notes on the action's "attach to matching GitHub Release" step here:
+# workflow_dispatch sets GITHUB_REF to the dispatched branch, not the
+# tag, so the action's tag-detection short-circuits and skips the
+# attachment. That's the right behaviour here -- we're recovering from
+# an Aminet-side problem, the GitHub Release page already has its
+# assets, no need to re-upload them.
