Reproducibility Materials for Domain Recognition Is Not Target Page Attribution in Generative Search

This repository contains the frozen protocols, experimental panels, anonymized API-output archives, analysis code, robustness analyses, and SHA-256 integrity manifests supporting the study “Domain Recognition Is Not Target Page Attribution in Generative Search.” The materials cover the W1/W2 analyses, the counterfactual experiment, the 2×2 factorial experiment, technical URL-equivalence audits, semantic-relevance validation, manipulation checks, and top-10 robustness analyses. Records can be linked to their frozen panels by call_id. No API key, credential, or personal identifier is included. The protocols were timestamped before the corresponding results were observed, but were not registered in an independent preregistration registry before execution.Version 2 adds the independent-domain external validation materials for Nurus, Kale and Egepen Deceuninck, including frozen panels, raw API outputs, analysis code and audit outputs.
