+"""Regression guard for #62151 — gateway cron must not wedge on 2nd+ API call.
+
+Gateway-fired cron jobs hung forever on the 2nd+ non-streaming API call when
+``interruptible_api_call`` spawned a daemon worker inside nested cron thread
+pools. The worker logged client creation but never opened a TCP connection.
+The same job succeeded via ``hermes cron tick``. Cron has no interactive
+interrupt surface, so the fix routes cron through a synchronous direct call on
+the conversation thread instead of the interrupt worker.
