Maintainer request: a 'Why' overview across projects as a tab under 'All projects', next to Agents and Jour fixe. First check what the hub offers: if no cross-project read exists, list per project from the existing endpoints or name the contract gap to the lead before building. Each project's visibility rules stay as they are.
