Add a numbered design doc to docs/design and keep the index and older docs' Status headers truthful. Use when a change alters an accepted decision — a new interface, a new Google Cloud dependency, a change to the auth model or a surface.

Cut an ochakai release — the version-bump PR, the annotated tag, the release body, and the post-tag verification. Use when asked to release, cut a version, tag, or prepare a release PR.
