 name: ARM64 Build
 
-# Triggers on push to main and on tags. Skipped on PRs to keep PR feedback fast;
-# manual via Gitea UI ("Run workflow") if needed.
+# Smoke-test workflow for main-branch ARM64 builds. Triggers on push to main
+# (so we catch breakages early) and on manual dispatch.
+#
+# Tag pushes are intentionally NOT a trigger — release.yaml handles tags and
+# also produces the disk image. Triggering both on the same tag wastes an
+# hour of Odroid time on a duplicate kernel build.
