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

Across prompted LLM classifiers and supervised Chinese encoder baselines, we find a consistent mismatch between generation fluency and reliable detection ability: the signal is textually learnable in-domain, but not robustly accessible to prompt-based classification.

C2weakest assumption

That the XHS-SCoRE benchmark, built from first-person reader labels on Xiaohongshu posts, accurately and stably captures the psychologically real construct of social comparison rather than artifacts of the platform or labeling process.

C3one line summary

LLMs generate social media posts that shift readers' perceived standing and comparison-related feelings but fail to reliably detect the same social-comparison triggers via prompt-based classification.
