Lake Catalog Governance

Give your S3 lake a second, independent account of what it is supposed to look like.

The Glue connector governs what makes a lake a lake: every table carries its S3 Location as the physical name, columns and partition keys arrive as Elements with Hive types preserved verbatim (partition keys flagged glue.partitionKey), and the recorded audit names the catalog-hygiene gaps Glue itself never complains about - tables with no description (table-no-description), tables with no classification parameter so crawlers and Athena treat the format as unknown (classification-missing), and struct/map/array columns whose inner schemas enter the lake ungoverned (semi-structured-column). The governed model becomes the place to attach the definitions and allowed values Glue gave you no place for.
