Side A introduces substantial new project functionality, including a reducer and ranking engine with tests, a parser framework, browser UI plumbing, vote handling, form-template processing, and supporting scripts. Although it contains some low-quality artifacts (such as pasted terminal prompts and planning notes), it establishes major reusable infrastructure, whereas Side B only makes a small maintenance change by updating the GitHub Actions Node version and removing a few obsolete tests.
