Claims use Slick as a typesafe embedded DSL and a new library called Sloppy to build query transformers that compose into a single SQL query so you avoid N+1 round trips. Techniques power a generic RDF-ish layer and an entitlements system that reduced ~300k lines of PHP to ~10k lines of Scala in production. Sloppy itself is not yet production-deployed, compilation and implicit shapes are tricky, and common-table-expression support is missing.
