Over five months, contributed to the ftsrg/theta repository by engineering core enhancements to model checking, trace generation, and witness validation workflows. Focused on improving analysis fidelity and maintainability, the work included refining the witness data model, integrating YAML and GraphML witness export, and advancing control-flow and AST representations. Leveraged Java, Kotlin, and Gradle to implement robust CI/CD pipelines, automate testing, and streamline build management. Addressed both feature development and bug fixes, such as cycle detection, metadata handling, and termination flow, resulting in more reliable verification, faster debugging, and a scalable foundation for future formal methods and software analysis initiatives.
November 2025 highlights: Delivered targeted improvements across the Theta analysis pipeline, focusing on correctness, configurability, and stability. Key capabilities added include a dead ends removal flag to tune pruning, WP computation for nondeterministic calls, support for skip statements in the occurrence checker, and a switch of the bounded model checker to BOUNDED mode. Witnessing and diagnostics were broadened with return-only witnesses, trivial witnesses, overflow witnesses, and graphML witness work-in-progress, along with fixes to witness handling and metadata. Core reliability was increased via fixes to the best effort target column, function call location, and reachability validation, alongside extensive test maintenance, test relocation, and version bumps for release. These changes collectively improve reliability, traceability, and developer productivity, enabling faster iteration and more trustworthy analysis results for business-critical modeling tasks.
