"""Regression: auxiliary-client keepalive httpx client must honor custom CA bundles.

The main OpenAI client resolves per-provider ``ssl_ca_cert`` / ``ssl_verify`` and
``HERMES_CA_BUNDLE`` via ``agent.ssl_verify.resolve_httpx_verify``. Auxiliary calls
(compression, vision, web_extract, title generation, session_search) build their own
keepalive client through ``agent.process_bootstrap.build_keepalive_http_client`` and must
apply the same TLS settings — otherwise an HTTPS custom_providers endpoint signed by a
private CA works for chat but fails ``APIConnectionError`` on every auxiliary task.
