Material changes to the website structure, survey framework, and literature data.
Added a complete English research interface and re-audited abstract provenance across all 239 records. The update fixes DOI content-negotiation misses, adds primary sources from NBER, arXiv, publishers, institutional working papers, and original PDFs, and strengthens provenance validation.
Consolidated fifteen overlapping tutorials into four sections aligned with the survey and simplified top-level navigation.
Established the homepage, literature database, paper records, topic and method indexes, knowledge maps, and editorial-methodology pages.
Expand evidence coding, import additional references from the survey, and prepare a versioned Zenodo release.
