vocapableworkspace_knowledge_version_moved
A newer knowledge version was published after this was raised; nothing changed. current_version says which is current - check again against it.
Problem shape
Every non-2xx response is an RFC 9457 application/problem+json body. The type URI below is stable and machine-matchable, so branch on the final path segment (the code) and treat the status as redundant confirmation. See the error-handling guide.
