What are you trying to protect yourself against?

1. Microservices imply distributed computing. So work with the grain on that - which is basically message passing with shared nothing resources. Most microservices try to do that so we are pretty good from a technical pov

2. Semantic loops - which is kind of what we are doing here with poly trees. This is really trying to model the business in software

Now here comes the hard part - this is not merely hard it’s sometimes bad politics to find out how a business really works. Is think far more software projects fail because the business they are in is unwilling to admit it is not the shape they are telling the software developers it is. Politics, fraud or anything in steer.
