DRFE-R v0.1.0 — First Public Release Hybrid compact routing combining Poincaré Isometric Embedding (PIE) with Thorup-Zwick distance oracles, with the first empirical study of TZ routing degradation under adversarial churn. Highlights Adversarial churn resilience: Targeted removal of 20% of high-degree nodes collapses standard TZ reachability to 0.7%. Our rebuild mechanism restores 100% reachability in ~50ms. Hybrid routing: Gravity → Pressure → TZ → Tree fallback chain achieves 100% delivery with stretch 1.6–1.7× across all tested configurations. Multi-seed reproducibility: All scalability results verified across 5 independent seeds (42–46) with 95% confidence intervals. Rayon-parallelized TZ build: Landmark BFS and per-node bunch computation run in parallel for faster preprocessing.
