Reproduction Package and Data for Article 'Why the Proof Fails in Different Versions of Theorem Provers: An Empirical Study of Compatibility Issues in Isabelle'

<br>This is the artifact accompanying the study of compatibility issues in theorem provers, accepted for presentation at the ACM International Conference on the Foundations of Software Engineering (FSE) 2025. This artifact includes both the collected data and the reproduction package for data preparation and analysis.The source code was developed by the authors of the paper. The data were collected through regression testing of different versions of the Isabelle theorem prover on the Archive of Formal Proofs (AFP), a large repository of formal proof developments. Compatibility issues were identified during this process, and relevant data were extracted and analyzed using the source code.
