+prompt_toolkit treats c-j (LF) as Enter on POSIX so thin PTYs (docker exec,

+# When a single test forgets to mock either ``os.kill`` or the global

+# correlated with a ``tests/hermes_cli/`` pytest run starting up.
+#
+# This fixture makes the leak impossible by intercepting the two

+#  • ``os.kill`` rejects any PID outside the test process subtree with
+#    a hard ``RuntimeError`` so the offending test gets a stack trace
+#    instead of silently murdering the real gateway.
+#  • ``subprocess.run`` / ``subprocess.Popen`` / ``call`` / ``check_call`` /
+#    ``check_output`` reject any ``systemctl ... <verb> hermes-gateway``

+``cron/scheduler.py:run_job()`` constructs ``AIAgent(...)`` directly without

+paths do at startup. Cron jobs therefore never saw any MCP tools from
+``mcp_servers`` in config.yaml. See #4219.
+
+The fix inserts ``discover_mcp_tools()`` before the ``AIAgent(...)`` call,
+wrapped in try/except so a broken MCP server can't kill an otherwise
+working cron job. ``discover_mcp_tools`` is idempotent — subsequent ticks
