8. Keeping the graph accurate

Every change is checked against all four layers of the graph before it can merge. An agent called the PR Validation Agent runs this check on every pull request before it merges into the main branch. The check fails when a change misses a required outcome, duplicates an existing design component, crosses a service boundary, or breaks something that depends on it. When the code changes, the KG Sync Agent updates the graph before the pull request merges, so the graph matches the main branch. The health of the graph itself is measured too, with twenty-nine metrics and fourteen verification checks. A merge that fails one of the most critical checks is blocked until the problem is fixed. The four custodians stay human. Each custodian works with information that exists only in conversations and decisions between people, such as customer calls, compliance decisions, vendor contracts and user research. No system an agent can read contains that information. Agents draft updates to the graph for the custodians to approve, and enforce the graph when code merges.
