+# These tests check the integration between asimov and cbcflow.
+# They are allowed to fail (continue-on-error: true) because:
+#   - cbcflow is an optional external dependency
+#   - some failures reveal known issues to be fixed incrementally
+#
+# Run on the same branches as the main test suite so failures are visible.
