"""Transient-transport retry count + per-model client-cache isolation.

Two related hardening behaviors for auxiliary calls (which include MoA
reference advisors, a pinned-model path where provider fallback is not a
meaningful recovery):

1. A transient transport blip (connection reset / timeout / 5xx) is retried
   on the SAME provider several times with backoff before giving up — a single
   upstream blip should not silently lose a pinned auxiliary call (root of the
   run2 double-advisor "Connection error" collapse).
2. Two auxiliary calls to the same provider/base_url/key but DIFFERENT models
   get DISTINCT client-cache keys, so a concurrent fan-out (e.g. opus + gpt-5.5
   advisors) never shares one client entry.
