Score: 7.3/10 (Innovation: 8, Technical: 8, Documentation: 7, Utility: 6)

Monolith generates live, typed SQL queries over Postgres from Java records using compile-time annotation processing, combining reactive subscriptions with real relational databases. It eliminates JDBC by directly calling libpq via Panama FFM, and provides a simple way to push UI updates from database changes without sacrificing SQL features. The project is experimental but offers a fresh approach to bridging Java and Postgres reactivity.
