Side B performs substantial, correct deduplication of duplicated HTTP/OAuth helpers and pass/fail harness code across four test files into test/common.bb and test/oauth.bb, reducing maintenance burden and bug-fix surface (e.g. consistent timeouts, unified mock-google logic). Side A is a small, useful config simplification (tests.edn glob) but is a single one-line-pattern change with lower overall impact and risk (e.g. auto-picking up unintended namespaces) compared to B's broader, well-executed refactor.
