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

Crystal outperforms a prior state-of-the-art impact classifier by +9.5% accuracy and +8.3% F1 on a dataset of human-annotated citations.

C2weakest assumption

That prompting an LLM to jointly rank all cited papers and aggregating via majority vote produces labels that reliably match human judgments of relative scholarly impact.

C3one line summary

Crystal jointly ranks cited papers' impact within each citing paper via LLMs with randomized ordering and majority voting, improving accuracy by 9.5% over prior classifiers on human-annotated data.
