Subject: [PATCH 1/2] scalar: add comments when setting config

From: Matthew Hughes <[email-masked]>
Date: Sat, 29 Nov 2025 17:22:18 +0000

This is to help users understand that a change in the config was made by
`scalar` (and not e.g. manually by themselves at some point in the
past).

As discussed on a thread[1].
