Legionary is a Muse Spark agent that shrinks quantum circuits and proves every rewrite is exact, so you get fewer gates, less noise and more reliable answers on real hardware. On a 3-qubit Grover search it cut 157 gates to 81 (48% fewer), 12 fewer than Qiskit's best setting, for about $0.08 per run on Muse Spark Open via Fireworks and Nebius due to failure upon meta api usage
