2.0.9
Fix completion payload uploads while Server is draining storage. On supporting Servers, uploads retry with the exact worker lease and immutable payload slot, using the existing admission-wait policy without re-executing handlers. Namespace quotas, hard storage fences and stale-lease errors remain authoritative.
Requires a Server advertising the optional completion-context capability (Server 2.3.5); behavior with older Servers is unchanged.
