"""Regression tests for #60955: gateway must not freeze fallback_providers.
|
|
|
|
Cron reloads ``fallback_providers`` from disk on every job. The gateway used to
|
|
freeze ``self._fallback_model`` at process start, so a chain configured (or
|
|
edited) after ``hermes gateway`` was already running never reached messaging
|
|
sessions — even though cron in the same process fell back correctly.
|
|
|
|
These tests pin the reload + cached-agent apply helpers without driving the
|
|
full Feishu session path.
