Notice: This repository contains the Preview Edition of the SPNED framework artifact. It includes the unified end-to-end toolchain automation scripts and pure C/C++ execution baselines. The core C++ Interval Abstract Interpretation Engine and unconstrained ORC JIT pipeline are strictly maintained in the SPNED-Core-Pro private repository.
Our multi-core scaling experiments and physical measurements systematically expose the architectural limitations of WebAssembly sandboxes in memory-intensive ingestion pipelines.
- Mathematical Bound Safety: The pure C++ abstract interpretation verification guarantees 100% structural safety and O(N) termination with a negligible 0.683 microseconds planning latency for fundamental operators.
- Zero-Copy JIT Bypass: Eliminates the batch size overhead tax (Sandbox Tax). SPNED achieves latency as low as 0.38 ns/tuple at large batch sizes, showcasing near-perfect L1/L2 cache affinity.
- Selective Throughput Dominance: In predicate-injected selective scanning, the unconstrained JIT engine decisively outperforms the Wasmtime sandbox context-switching limitations (e.g., 739 MT/s vs 604 MT/s).

Designed for distributed systems researchers targeting top-tier conferences and infrastructure engineers building production-grade ingestion layers.
