Estate Documentation Audit
Find every undocumented table and every ungoverned STRUCT/ARRAY/JSON payload.
The BigQuery connector reads the descriptions BigQuery already holds - COLUMN_FIELD_PATHS for columns, TABLE_OPTIONS for tables - into the governed model, and the recorded audit then names every gap on every run: undocumented tables and views (table-no-description) and columns whose STRUCT/ARRAY/JSON inner schemas are invisible to consumers and agents (semi-structured-column). The gaps stop being invisible, so they finally close - and the documentation you add in CoreModels can be generated back into the estate as OPTIONS(description=...) DDL.
