Original collectionUnder development

Under development — library extension. This report is part of the expanded-library work, not the original collection. Source preparation, methods and results are subject to revision.

Provisional eligibility assessment — under development. Outside the main collection until the source identification and original treatment coding are verified; missing data or an unsupported adapter alone does not establish ineligibility. The selected appendix specification is a summer-by-NBP-region-by-post triple difference with county-season, county-year and season-year controls. It requires a triple-difference adapter, rather than relabeling that interaction as ordinary treatment adoption. This working assessment is not fully vetted and may change. See the report below for its recorded replication or assessment status. Provisional eligibility log
