The OP of the WIKI post is the LLM bot/agent. And it is not like the AI summary button but more like an AI report/proposal/document as an outcome artifact of a discussion. The updates could be automated or on demand.
In many topics not every position could be merged in an unified artifact cause conflicts. So for these the AI bot is going to propose pools or new subtopic on specific conflicting points to try to focus and solve contrasting opinions (with extra discussion and then when out of a deadline with pools vote).
The group of topics are going to be selected by the moderators/administrators. This could be done manually then we will have a connection/relation between the Ai bot wiki post and the related list of topics ids.
I think this is the most interesting way to prepare and update baseline semi-automated artifacts from discussion.
Many communities require to have artifacts from discussions but it is a very time consuming task to create a manual artifact baseline.
