Research direction
Start by reviewing Paimon's catalog support and the Spark 4.1 check-constraint requirement described in SPARK-51207. Identify the catalog entry points and existing constraint handling before defining the required behavior. Done means Paimon catalogs support check constraints needed by Spark 4.1, with coverage for the relevant integration behavior.
