 ### Added
 
 - Workers with a sticky cache (`sticky_cache_capacity > 0`) advertise `sticky_history_suffix` (#300, server#1017). On Server 3.5.0 or later, a sticky hit receives only the history after the sequence the worker cached, instead of the full history on every workflow task. A suffix is used only when it continues the cached history exactly; otherwise the worker drops the entry and refetches full history.
