Path Oracles for Spatial Networks

Summary: Introduces linear-size path oracles compressing all n² spatial-network shortest paths into relational tuples via spatial coherence and WSPs. B-tree lookups retrieve path links in O(log n), with an ε-approximate distance/vertex variant for scalable SQL routing. (summarized by gpt-5.6-luna on Jul 24 2026)
