+"""Tests for gateway.platforms.telegram_network – fallback transport layer.
+
+Background
+----------
+api.telegram.org resolves to an IP (e.g. 149.154.166.110) that is unreachable
+from some networks.  The workaround: route TCP through a different IP in the
+same Telegram-owned 149.154.160.0/20 block (e.g. 149.154.167.220) while
+keeping TLS SNI and the Host header as api.telegram.org so Telegram's edge
+servers still accept the request.  This is the programmatic equivalent of:
+
+    curl --resolve api.telegram.org:443:149.154.167.220 https://api.telegram.org/bot<token>/getMe
+
+The TelegramFallbackTransport implements this: try the primary (DNS-resolved)
+path first, and on ConnectTimeout / ConnectError fall through to configured
+fallback IPs in order, then "stick" to whichever IP works.

+The OpenAI SDK's ``AsyncHttpxClientWrapper.__del__`` schedules

+fires during CLI idle time, prompt_toolkit's event loop picks up the task

+1. ``neuter_async_httpx_del()`` replaces ``__del__`` with a no-op.
