Evidence-gate codebook, 13-study benchmark coding, and Sears Point annualization audit

Supplementary workbook supporting the article “Evidence gates for coastal nature-based solutions: when monitoring outputs can support flood-benefit and investment claims.” The workbook contains the four-gate evidence codebook, coding for 13 published benchmark studies, source register, Sears Point scenario-loss matrix, formula-driven annualization audit, issue log, and figure register. Version 1.1.0 aligns the archived workbook with the final Journal of Environmental Management submission package. It updates manuscript figure and table cross-references, author and corresponding-author metadata, repository-version documentation, and removes obsolete prior-submission and internal revision artifacts. No scientific results, gate assignments, scenario-loss values, or annualization results were changed. The benchmark remains 39 Pass, 11 Partial, 2 Not applicable, and 0 Blocked across 50 applicable assessments. The workbook supports reproducibility of the reporting audit and arithmetic diagnostics. The original GIS geodatabases, raw rasters, scripts, and asset-level tables used in the audited 2026 source workflow were not retained and are therefore not represented as reproducible source data in this deposit.
