## Summary - detect when `getVercelToken()` replaces the stored access token - treat the replacement token as fresh so transient 401/403 responses are retried - extend the retry budget to cover delayed authorization propagation - recognize supported auth error shapes across package/bundle boundaries - add a regression test reproducing refresh followed by a transient 403 This was extracted from vercel#246 after local traces showed a successful OAuth refresh followed by a transient Sandbox 403; the same stored token succeeded seconds later.
