You might be wrong while saying:
I see the code dump in all the other default post types
Because your dump won’t show code dump on the default post type page, and here is where the clue lies – page is hierarchical.
If you see the documentation of post_row_actions, you can see the description saying:
The filter is evaluated only for non-hierarchical post types.
Meet with the page_row_actions
As your post type is hierarchical you have to use page_row_actions the counterpart for the hierarchical post types.
