Commit A combines a user-facing correctness fix with a substantially stronger end-to-end test. It changes vote URLs to use display paths instead of internal storage URLs, aligning generated links with the UI and DSL, and rewrites the browser test to exercise all 45 pairwise comparisons in a 10-item pool before validating the resulting ranking through the ranking API. That significantly increases coverage and verifies an important algorithmic property rather than just basic flow. Commit B is also valuable, restoring broken OAuth-based E2E authentication by fixing the mock servers and improving test helpers, but its changes are primarily test infrastructure and bug fixes for the mock environment rather than application behavior. Overall, A contributes more functionality and long-term regression protection.
