Enforces GrantForge policies in Trino 470 to 478 coordinators: a system access control that checks catalogs, schemas, tables, columns, routines, session properties, impersonation and the queries of other users against the service's signed policy snapshot, lists only what a user may use, applies row filters and column masks fitted to each column's type and folds repeated accesses into one audit event. One Java 23 jar for Trino's plugin directory.
