+# The release gate. src/config/jpa/release-registry.json is the source: every gate it declares has a
+# job or an assertion here, JpaReleaseRenderingTest holds this file's matrix and promotion lists to
+# the registry's Stable majors, and verifyJpaReleaseGateTasks resolves each gate's task against the
+# real Gradle graph. So a gate removed from the registry, or a major demoted in it, fails the build
 # rather than quietly ceasing to be checked.
+#
+# The matrix below is therefore not free to drift: editing it without editing the registry fails the
+# unit lane.
