Just checking out your fork, and very new to this. I wanted to report a potential issue that looks like it is coming from the initial rename of _s.
After install I see the following:
Call to undefined function _s_posted_on() in \wp-content\themes\scentric\bytefair-scentric-6238160\content.php on line 14
Change line 14 to:
<?php scentric_posted_on(); ?>
Change line 35 to:
if ( $categories_list && scentric_categorized_blog() ) :
thanks, I did forget to change these functions when porting new code.
