The versioning feature shipped 2026-08-17 (drafts, version history, rollback, tool version pinning) is dashboard-only. The AssistantVersion / AssistantDraft schemas already exist in your OpenAPI, but no endpoints reference them — /assistant is CRUD only.

Requesting API access to:

List / get assistant versions

Rollback to a prior version

Draft create / publish / discard

Pin a specific tool version

Expose configHash on the assistant (for drift detection)
