Thank you for taking a look. Yes. it is a custom compiled single .exe that contains the entire app shell and the 20 different apps all come s preloaded in the entire 6mb file. The file itself is an example of the output of my proprietary compiler and also the security measures taken to secure the app itself.
On the question of "How is it an operating system?" Excellent question. I don't think any adult would ever take this seriously. This is really a windows app. A parent my use it for an amusement before letting their kid play with it. It's meant to be kind of a "My First OS" for kids. The "App store" mimics what an appstore interaction is like (explains ratings, why trusted apps are better than sideloading (in general) and offers different apps to "download." Download triggers an animation for installing just like an app store (but it's all fake). All of the apps are all ready there. The theme store has 220 real css resleeves for the the entire app.
But, I made a mistake in the original file I uploaded and the terminal works, but it's not a true cli. The version I'm uploading as soon as I figure out how to make an edit is going to have a real nerfed cli. the student can have an api key configured. There are explanations of how to do this in both the kid's and the parent's manuals that come with the file.
The reason was just really simple. I just wanted to make something that was fun and useful and didn't collect any data from students and was private. And something that had cryptographically produced comprehensive audit trails so that parents could know ever single thing that cli did. It cannot do something and hide what it did. it cannot run or execute anything other than what it makes in its sandbox (it's only allowed to make spas and never something harmful) and, parents can set it up so that it sends a notification to them any time it wants to run anything.
