+# Manifest of base images mirrored into Harbor's base-images project.
+# One line each: <source image on Docker Hub> <target name:tag under base-images>
+#
+# All chosen as the leanest official variant that still keeps a shell +
+# package manager (not distroless — deliberate choice: homelab
+# debuggability via kubectl exec matters more here than the last bit of
+# attack-surface reduction). go/alpine were already minimal and are
+# mirrored unchanged; node/python/java/php all moved from their
+# Debian-slim (or, for php, full Apache+Debian) default to an Alpine
+# equivalent.
+#
+# Re-run mirror.sh after editing this file to add a language/version or
+# pick up a base image update — nothing here happens automatically.
