Hi @CM13, appreciate your feedback!
The members in the credit evaluation process are categorised as group members (e.g. the Credit Group).
Most of these you mention would fall under the k/f team which is the entity working on the Centrifuge protocol - but definitely good feedback to make these roles more clear.
The purpose of part 3 is to define the types of engagement in the DAO - not encouraging any particular action - and their privileges. This will ensure that people with the relevant expertise and engagement will have access to the appropriate channels to discuss the development of the protocol and keep the conversations constructive. Anyone can increase their Level of Engagement, depending on their commitment and/or expertise.
