The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

On citation prediction benchmarks with 169K arXiv papers, GSS achieves 23% relative improvement in Recall@20 over SPECTER+FAISS baselines.

C2weakest assumption

That the learned local Riemannian metrics meaningfully capture semantic relationships in the citation graph rather than merely fitting training patterns.

C3one line summary

GSS learns per-node low-rank Riemannian metrics on citation graphs and retrieves via geodesic distances, yielding 23% higher Recall@20 than SPECTER+FAISS on 169K arXiv papers.
