Azure Digital Twins / AWS IoT TwinMaker / NVIDIA Omniverseを semantic graph / visualization / process/physics/sensor simulation / agent integration の能力matrixで再採集する。\n5. ISO 23247 seriesのPart 1〜6と2025/2026 use-case TRを再確認し、manufacturing以外へ一般化する際は適用範囲を明記する。\n6. 後続live testは実設備を使わず、synthetic twinまたは公開sample sceneでscenario→simulation→policy gate→no-op promotionまでを再現する。"
