Answer my WP file loading architecture question

I've created a video about one of the major problem that I have. I need to understand the file loading architecture, how it's done when writing a class in WP plugin development (how one class knows about the existence of another class), and how this compares with WP MVC file loading architecture. It's one big question, and I went through the various smaller questions that helped me arrived at the question summary in the video here: [login to view URL] I'm putting the plugin code in the Google Drive folder also: [login to view URL] I need you to start a screen-recording session (use Screenpresso or the like), and record an MP4 video, or we can have a live session, where you explain to me the architecture of file-loading in WP, and how it works in WP MVC. I need a flat rate, and what type of session you will give me (MP4 or live session)
