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. PDF audit reopened this assessment; no new comparison is admitted. Paper defines theater integration as binary. Library R preparation averages vi to theater-year (R/112_gil_replicate.R), creating fractional annual exposure; headline vit is a post-divestiture trend interaction. Reconstruct appropriate timing/target before fitting; do not threshold annual means or call the policy intrinsically continuous. This working assessment is not fully vetted and may change. See the report below for its recorded replication or assessment status. Provisional eligibility log

Template assessment

The source vertical-integration regressor is fractional, not a binary adoption indicator. The comparison is withheld rather than thresholding it.

No comparison point or homogeneity-test decision is assigned to this paper.

The source regression was re-estimated on 2,683 observations before this assessment.
