Did you read the readme of the framework? I included a short explanation on how to set up a content pack there. Feel free to ask for clarifications if something is unclear!
There were two issues: you did not name your folders correctly, and one of your files was not valid JSON, as you had an additional closing curly bracket in an objective definition. The next version of the framework will display the filename on syntax errors, which makes these errors easier to fix.
Download the updated content pack to see my changes. Other than that, I ran everything through a formatting tool to make the files more readable, but kept your file names. File names are used for sorting in the UI and the "campaign" created for escalations: it might look better if you use the actual names instead of codenames there in the future.
