Merge Risk: 🔵 Low · up to 21aa1

The documentation should identify that a human PlatformAdmin must create service-bound keys; otherwise users may follow the runbook and encounter authorization errors. The PR is otherwise mergeable with explicit owner follow-up on this bounded documentation risk.

Use “principal” in the model overview.

Lines 17-18 still limit roles and role bindings to users. Line 131 now includes groups, wildcard bindings, and service accounts. Replace “users” with “principals” in this overview.

Use the unprefixed ID only when creating the key with
`nemo auth access-keys create --service-account intake-reader`. NeMo stamps the
token subject as `service-account:intake-reader`.

State the required creator role.

A human PlatformAdmin must create a service-bound key. The implementation rejects service-account callers and non-admin service-bound key creation. Without this prerequisite, users can follow this command and receive an authorization error.
