  "scenario": "A pull request introduces the new Payments service and its Stripe SDK integration. The Orders service gains an outbound edge to Payments. The reviewer sees the diff, the rendered before-and-after diagrams, and a single comment summarising the architectural impact - far easier than re-reading the source diff to figure out which services are now talking to which."
