Draw your own three-concern split

The prompt

Draw your own version of the platform split: which part of your system does reasoning (the model), which part does engineering execution (repository-centered work), and which part holds enterprise authority (identity, policy, logging, deployment)? Name the actual service or team behind each box.

Why it's built that way

The handbook's platform is intentionally split into three concerns — reasoning, engineering execution, and enterprise authority — precisely so that AWS identity, policy, network, logging, security, and deployment services determine what actions are permitted, not the model itself.

What to do with the answer

If any box is empty (nothing currently holds "enterprise authority"), that's this week's highest-priority gap.
