The $ci is evaluated only once for each received request/reply.
There's no need to re-evaluate for each route.
There are special cases when re-evaluation is necessary: when changing
the message and changes are forced to be applied inside the script or
when async operations are performed and variables inside the prefix
can change. None of these applies to your deployment.

I'm not sure I follow you here. The modules are loaded before the
script is evaluated.

I don't need to search, I know the answer :)
Here's the command: kamctl rpc core.modules


I'm not trying to push anything on you. If you don't feel comfortable
running logs in "verbose" mode and prefer to reproduce and
troubleshoot issues after business hours, that's totally fine.
