About the Bounties category

Is this thread for bounties that are already listed in separate GitHub repository?
Is it intended for CCS-style bounties?
Or is this thread meant for both types of bounties?

If there are CCS-style bounties that require changes in a Tari repository (e.g., for Tari Universe), how can we get approval from Core Contributors to work on them? Since the community may propose a bounty for desired functionality, but we won’t be able to merge it into the target repository without Core Contributor approval, it would be preferable to get approval before starting the work and funding, so that the effort is not wasted.
Should we request approval from Core Contributors in this topic, or is there another place for that?
