Supplementary Materials for When an AI Relationship Does Not Travel

Supplementary materials for the manuscript "When an AI Relationship Does Not Travel: User Judgments and a Cross-Endpoint Audit of Relational Portability." The package contains the deidentified Study 1 search log and Study 2 verification materials, including the study protocol and prompts, representative synthetic materials, profile-level derived results, and reproduction code. Raw Xiaohongshu posts and comments are not included because they contain sensitive relational narratives and potentially identifiable third-party information. The materials are provided to support transparency and verification of the reported analyses.
