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

Our approach achieved a micro-F1 score of 0.866, demonstrating competitive performance compared to the leading models.

C2weakest assumption

That the combination of guideline-integrated prompts, curated few-shot examples, self-consistency, and post-processing will produce reliable structured outputs on unseen clinical notes without extensive per-site tuning or validation.

C3one line summary

Reasoning LLMs using concise prompts, few-shot examples, self-consistency, and post-processing extract SDOH events at micro-F1 0.866, matching leading BERT models.
