PIDT Eligibility and Screening Protocol — Version 1

This protocol documents the scientific eligibility criteria and staged evidence-screening workflow used in a review of physics-informed digital twins. It covers bibliographic consolidation, two separately executed AI-assisted title-and-abstract assessments, author-performed RQ-specific evidence prioritization, independent full-text-acquisition prioritization by two human screeners neither of whom was the article's author, full-text retrieval, and author-led page-grounded analysis and synthesis across four research questions.
