Side A fixes several real bugs (regex split instead of string split, correct getRequestBody, nil-safe state/token handling, proper error handling to prevent silent hangs) that were causing legitimate test crashes in the OAuth mock infrastructure, restoring E2E test reliability. Side B is a reasonable simplification/refactor of a UI action into inline SSR, but it's a smaller-scope cleanup with less clear bug-fixing value and removes test coverage without adding new safety guarantees.
