I don’t believe so, for Graphics Contrast it would need to be: “A graphic or section of a graphic that represents a distinct object or sub-component with semantic meaning.”
It not a “distinct object”, it is a border around text (in the general rather than CSS sense of border), rather than something conveying its own meaning.
Side-note for Glenda: Presumably blocks of text do not constitute a “user interface component”?
Without the “interactive” term in the title, that’s less clear now, but not necessarily a problem.
> - Is the box is "essential"?

I would say no, because:
> There is a non graphical alternative, the word "Proposed".
And then where you say:
> There does not appear to be a provision for a text alternative under this SC.
That’s part of the core SC, a graphic is not “essential for understanding” if there is a visible text alternative.
NB: There used to be an explicit exception for conforming alternates, but we had comments to take it out as it duplicates the core text.
Another sidenote: The CSS for the border is “width: medium”, which is >3px so if it were covered then 3:1 would be ok, which is: #CC8800 (murky brown?!).
