Side B adds a real, coherent feature (Reddit OAuth linking with UUID-as-canonical-identity), including conflict handling, trust-weight batching fixes, private linked-provider listing, and updated test harness/mocks—net positive functional and architectural value. Side A mostly deletes a large but working (if arguably over-engineered) parser graph and its tests, replacing it with a much simpler regex-like parser and a paste-and-go UI, which is a reasonable simplification but is largely destructive/refactor-y rather than adding new capability, and it removes test coverage (parser_race.clj) without clear compensating value.
