Side B implements a real feature (Reddit OAuth linking with UUID-canonical identity, conflict handling, private linked-provider display, batch-consistent trust weight updates) plus corresponding test infrastructure updates, delivering concrete user-facing and security-relevant behavior. Side A adds a well-tested URL canonicalization graph, which is solid engineering but a narrower, self-contained utility with less integration risk and lower overall product impact than B's auth/identity change.
