In many real‑world deployments—autonomous drones, collaborative robotics, smart‑city sensor grids—the inference workload is distributed across a decentralized swarm of heterogeneous agents. These agents must continuously share context, model updates, and sensor observations while operating under strict bandwidth, power, and latency constraints. ...
