Does Casbin support distributed PDP, central PAP, and ABAC attribute sync?

Hi All, I am looking at using Casbin/Casdoor for authorization. Can someone help me answer below questions

1. Does it support Distributed PDP option or offline support, Can you share some supporting document on this?
2. Does it have Central PAP? Any documents for this too?
3. How does Sync between central PAP and distributed PDP happens?
4. How to get attribute values in ABAC, any flow for this or document to understand?

why not read docs first?

Thats what I am trying to find 🙂 I could not get these answers from the doc thats present, if you can guide me to the document will be good

Do you have any architecture document?
