Side A performs a substantial structural refactor introducing a typed ItemId enum to replace stringy CanonicalItemUrl across the reducer, ranking, RPC, and HTML layers, plus splitting wire-normalization logic into item_wire.rs, touching many core files and tests consistently. Side B is a smaller but genuinely useful bugfix to test-only mock OAuth/reddit servers and Clojure test helpers (fixing regex splits, request body vs input stream, redirect codes, error handling), which is real but narrower in scope and confined to test infrastructure rather than production code.
