Repository/deferred lanes use the real BaseRepository. The separately labeled drizzle-relational strategy executes native findMany with one lateral JSON aggregation statement and its own result mapper through the same pool. Same selected columns and bound predicates; unordered graph equality is checked outside timing. All statements use the unprepared unnamed extended protocol. Trace timings are instrumented and excluded from clean ranking; roundtrip includes driver/network/server. Other time includes JS attachment, uninstrumented native relational compilation and async scheduling, not pure CPU.
