Side A fixes concrete failures in the OAuth end-to-end test infrastructure by correcting query parsing (`str/split` with regex), reading POST bodies from `getRequestBody`, handling null tokens/states safely, adjusting redirects, wrapping mock handlers with error handling, and improving Playwright DOM polling so authentication flows work again. Side B is primarily a UI enhancement that refactors `cli_panel` to support grouped clickable commands with styling and adds assertions for JS-safe command strings, which is useful but less foundational than restoring broken authentication tests.
