When standard lineages merge or branch: Organizational continuity and structural reorganization — analytical data, models, and verification materials

De-identified edge-level analytical data, organization-continuity model data, model outputs, representative-family verification materials, figures, and executable Python code supporting the article “When standard lineages merge or branch: Organizational continuity and structural reorganization”. The deposit analyzes 20,900 directed replacement relations among 113,393 industry-standard records and distinguishes linear succession, many-to-one merging, one-to-many branching, and complex reorganization. The integrated raw metadata corpus and individual drafter names are not redistributed. The edge-level analytical data contain only the minimum fields required for reproduction, while the organization-continuity data contain aggregate organization counts and similarity measures rather than organization-name strings. The package includes executable analysis code, dependency information, reference and independently reproduced model outputs, representative-family verification materials, manuscript figures, file inventories, and SHA-256 integrity checksums.Data, documentation, and figures are licensed under CC BY 4.0; source code is licensed under the MIT License.
