Overview

Factory for dialect-specific SQL query builders used by the analysis classes. Each builder is a stateless module exposing class methods that return raw SQL strings; the analysis class is responsible for executing them and mapping result rows into output hashes.

Builders intentionally output a stable column-name contract so that downstream transformation logic doesn’t need to know which dialect produced the rows. See QueryBuilders::Mysql and ::Postgresql.
