~anthropic/claude-sonnet-latest → B (6:4)

B performs a genuine type-safety refactor, replacing loosely-typed String item paths with CanonicalItemUrl throughout the RPC/validation layer and adding Deref impls to reduce boilerplate, which reduces bug surface and clarifies invariants across the codebase. A adds a real user-facing feature (reddit post rendering with images/links) with decent test coverage, but it's more localized and additive rather than improving the correctness/maintainability of existing core logic; B's changes, while less flashy, touch more fundamental plumbing that lowers future defect risk.
