The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Results show that the commit-aware TCP significantly outperform non-commit-aware-baselines in both classification and prioritization effectiveness.

C2weakest assumption

That structural properties extracted from version-control diffs add predictive value beyond test coverage and historical execution data, and that the learned model generalizes under leave-one-project-out cross-project validation without project-specific tuning.

C3one line summary

A commit-aware learning-based test case prioritization technique using diffs, coverage relations, and history outperforms non-commit-aware baselines on five Defects4J projects under cross-project validation.
