+## Container release retention
+
+After a tagged release passes candidate verification and is promoted to Dev, the
+container workflow keeps the current immutable `sha-<commit>` image and the most
+recent previous release by default. Set `release_retention_count` on the caller
+to retain a different positive number.
+
+Retention only matches versions in `sha-` followed by a 40-character commit
+hash. Registry versions named `sha256:*`, `ci-cache`, or anything else are never
+selected for deletion by this step.
