resolve_minimax_oauth_runtime_credentials called _refresh_minimax_oauth_state
without a try/except, so a terminal failure (invalid_grant,
refresh_token_reused, invalid_refresh_token) raised AuthError but left
the dead refresh_token in auth.json. Every subsequent API call retried
the same token via a network round-trip, failing identically each time.
Fix: wrap the refresh call and, when exc.relogin_required is True and a
refresh_token is present, clear the dead OAuth fields (access_token,
refresh_token, expires_*) and write a last_auth_error quarantine marker
to auth.json before re-raising. The next call sees no access_token and
fails fast with 'not_logged_in' — no network retry — and the user is
prompted to re-authenticate.
Mirrors the existing quarantine pattern for Nous (_quarantine_nous_oauth_state),
xAI-OAuth (#28116), and Codex-OAuth (#28118). Persist failure is
best-effort (logged at DEBUG, error still re-raised).
Salvaged from #28003 by @EloquentBrush0x — contributor's branch was
severely stale (would have reverted ~5000 LOC across azure/kanban/i18n
subsystems); fix re-applied surgically with their pattern preserved and
added two regression tests (terminal-quarantines + transient-does-not-quarantine).
