Data and materials for: Selected-holdout feasibility and failure-mode testing of a source-verification workflow for reporting-guidance item sets

This dataset contains protocols, coding forms, adjudication files, derived datasets, analysis outputs, tables, manuscript materials, and scripts for a methods and meta-research study developing a modular source-verification workflow for reporting-guidance item-set sources in clinical epidemiology. This version is the full source-reopening dual-reviewer Protocol-v4 package. It includes package-relative Protocol-v4 scripts, a run-all reproducibility QA runner, a fresh-unzip reproducibility report, completed two-reviewer manual source-reopening audit files for all final strict-L5 yes rows, object-specific Protocol-v4 eligibility rationales, and auxiliary packets for Protocol-v5 source-frame rebuilding. The manuscript treats the 16/22 endpoint as selected-holdout full source-reopening dual-reviewer verified strict-L5 feasibility, reports corrected 103/119 dual-reviewer reopening-route agreement, and retains 0/22 strict independent exact-location concordance as a distinct reproducibility finding.
