Tikz hierarchical diagram with multiple parents

You could also draw different trees and connect them like so, but maybe this is not a very precise solution:

\documentclass[tikz]{standalone}

EDIT Bit less incomplete now, but still not completely complete.

Here's a (currently incomplete) Forest version. Adding the labels at the left of the tree is straightforward - there are a number of questions with answers demonstrating ways to do this. It isn't really clear if the messiness of the original is essential to the diagram, but that can be added if required.

<code>block tree</code> non-tree


Well, I try to make a code with brute force a little more summarized, but I was blocked, I know there is a lot of code that could be improved, but I managed to control the widths and separations, colors, and I do not know why I'm going to those extremes, but if it's helpful...

Here is the code.
