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

structured clinical semantic supervision can improve low-resource adult-to-pediatric ECG transfer

C2weakest assumption

The Gemini-generated label-conditioned semantic descriptors accurately capture clinically relevant ECG semantics and provide effective auxiliary supervision without introducing bias or noise, despite the absence of paired clinical reports.

C3one line summary

PEACE framework aligns adult and pediatric ECGs via tri-axial semantic decomposition and LLM-generated auxiliary supervision, achieving 59.39% zero-shot to 90.89% full fine-tuning AUC on ZZU-pECG.
