Akua verifies the supplied version metadata against the published artifact before durable registration. Requires published Package import access. Hosted packages publish versions through the package creation workflow. ## OpenAPI ````yaml /openapi-public.json post /packages/{id}/versions openapi: 3.1.0 info: title: Akua API version: 1.0.0 description: >- Public API for managing Akua workspaces, clusters, products, and installs. Authenticate with a workspace API token via the `Authorization: Bearer sk_akua_...` header. A workspace-owned token implies its workspace.
