Side A performs a genuine architectural cleanup: separating identity parsing/validation into a dedicated module, removing ad-hoc identity rewriting from the reducer, making delegate optional, and consistently updating wire/HTML boundaries with matching test and CLI updates across the whole codebase. Side B is a solid, scoped bugfix (forcing OAuth and retry-on-401/403 for Reddit fetches) with good error truncation and a test, but it's narrower in scope and impact compared to A's broader identity-model correctness fix that touches API contracts, storage, and display logic throughout the system.
