+# build-vibedata-image.yml (auto on push to main, multi-arch, signed, version-
+# resolved). This workflow is retained for reference only: it builds the image
+# to validate the Dockerfile but does NOT push, sign, tag, or scan a registry
+# image. A past manual dispatch of this workflow is what left the stale
+# obot-vibedata:main tag in the registry.
