Thank you for the thoughtful explanation, I agree that longitudinal participant tracking would be incompatible with the privacy principles the program is meant to teach.
The aggregate, in-the-moment reporting approach you outlined makes sense: attendance, hands-on wallet installations, in-workshop transactions, apprentices trained, and publicly declared merchant acceptance can make the work legible without linking private individuals to later activity.
I appreciate the clarification and the distinction between accountable reporting and turning participants into a dataset.
