How Governance Enforces Review
Once ownership is configured, Hub applies it automatically when a proposal is created. The Reviews section in the proposal sidebar lists every required reviewer grouped by Subgraphs and Types, with their role shown in parentheses. A reviewer must approve before the proposal can be merged. Unresolved discussion threads also block approval and appear as a failing Hub check in the checks panel.Owners assigned to the graph admins, subgraphs, and types that need coverage. From this point, every proposal that touches an owned resource automatically routes to the right reviewer.
