BACKEND BENCHMARK RUNNER
The backend instruments itself: the same four workload tasks run through competing systems and every run emits a BenchmarkRecord — the common measurement language. GRAVITY-Static pins the kernel OFF, so the delta between the two GRAVITY rows IS the architecture's contribution.
Why spend frontier-level intelligence when lower-cost computation is sufficient? Same task · same input · same criterion — measured evidence only.

Worked example — L0 python $0.000 · stats $0.001 · small LLM $0.008 · verify $0.002 · orchestration $0.001 = $0.012 vs one frontier call $0.06–0.10.
