A live verifier test wedged for ~19h: a judge endpoint returning HTTP 401 (mapped by the openai SDK to AuthenticationError) hit the AuthenticationError branch, which neither blocklisted the endpoint nor consumed the `tries` budget — so next_client() kept handing back the same failing endpoint and the loop spun forever, opening connections the whole time. - AuthenticationError and the check-access-response-enc branch now decrement `tries` (and AuthenticationError backs off 1s) so a persistent auth/access failure on a small pool can't loop forever. - Add a hard `max_total_attempts` cap (default max_retries + 2*n_endpoints) as a backstop: create() always terminates regardless of which branch fires, including blocklisting paths that intentionally don't spend the budget. - Exhaustion error now reports total_attempts + both caps. - Tests: 3 regression cases (persistent-auth termination across 1 and 3 endpoints, all-endpoints-blocklisted termination), each guarded by a 30s asyncio.wait_for so any future regression fails loudly instead of hanging.
