Overview

The base URL, the version, and what this reference covers.

This page is a placeholder. The writing lands in slice 7, against the source rather than from memory.

123operations documented here, of 258 the runtime serves, across 17 groups.

Platform administration, which is operator surface and not a customer capability.
