QStream: Deterministic Querying of Data Streams

Summary: QStream replaces best-effort stream processing with deterministic real-time query evaluation, guaranteeing negotiated precision and latency under varying loads. Its operator model, resource descriptions, and QoS negotiation target time-critical sensor-driven control. (summarized by gpt-5.6-luna on Jul 24 2026)
