🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
Transient 4xx token-endpoint statuses are classified as permanent rejections, and no test pins the boundary. The status >= http.StatusInternalServerError split sends 429 Too Many Requests and 408 Request Timeout into the rejection branch, which writeExchangeError turns into session deletion plus 401. An IDP throttle therefore logs out every active user. The error-classification table does not cover either status, so the boundary is unverified.

🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win
Delete the effective subject token on exchange rejection.
After doRefresh stores the rotated session under refreshed.AccessToken and deletes the old key, handleProxy keeps the old value in the request cookie. If upstreamToken returns auth.ErrExchangeRejected, writeExchangeError deletes that stale key and leaves the rotated session, including its refresh token, in the store. Pass the effective jwt from both callers.
