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

a strong retriever baseline drops from 66.4% PerfRecall@10 on 4-hop General-Wiki to 5.0-27.9% PerfRecall@10 at 4-hop depth, revealing robustness gaps that current benchmarks fail to capture.

C2weakest assumption

That decomposing documents into atomic facts plus CRRF rank-fusion produces benchmark data that faithfully reflects real-world redundancy and quality without introducing new artifacts or biases.

C3one line summary

RARE builds redundancy-aware benchmarks via atomic fact decomposition and CRRF-enhanced LLM generation, showing retriever PerfRecall@10 dropping from 66.4% on general data to 5.0-27.9% on high-similarity finance/legal/patent corpora.
