+# Component-specific companion to the canonical release-tag.yaml. On a release tag, after the
+# multi-platform image is published, open a PR into the consuming chart (core-provider-chart)
+# bumping cdc.image.tag to the released tag — so the chart deploys the just-released CDC
+# instead of the previously pinned version.
+#
+# This lives in its own file ON PURPOSE: release-tag.yaml is byte-for-byte identical across
+# all component repos, so a CDC-specific bump must NOT be inlined there (it would be clobbered
+# on the next canonical sync). Triggered by the same tag push, so it is "wired into" the
+# release in effect, without mutating the shared workflow.
