Sorry, not sure how the docs work. I've amended the referenced line number for encode but it's still red.

Seems valid indeed:

Thanks for adding.

I found these snippets:

https://psalm.dev/r/2106809556

<?php
$res = json_encode(null);

/** @psalm-trace $res */

Psalm output (using commit 275dfd8):

INFO: Trace - 4:25 - $res: false|non-empty-string

INFO: UnusedVariable - 2:1 - $res is never referenced or the value is not used
