ARK-490 — Authority Engine · Sustained Throughput

ARK-490 — ExecutionProof P02 Latency/Throughput/Scale series by Remnant Fieldworks Inc. Measures sustained throughput of the reference Authority Engine over a 60-second window and degradation versus burst (ARK-489). Verdict: PASS. 2,491,235 dec/s sustained over 60s at 100% accuracy (~81% of burst); threshold ≥100K. Correctness gate PASS. Covenant: outcomes preserved as measured; claims bounded to the tested in-memory reference under single-threaded load. Component performance measurements — not legal, patent, security, or production-readiness proofs. Soli Deo Gloria.
