etcd linearizable reads + monotonically increasing resourceVersion ensure ordered updates.
Quick Answer
The API server processes updates to the same object sequentially because etcd is the serialization point — only one write can succeed per resourceVersion. All updates go through etcd's Raft leader, which applies them in order. Watch events are delivered in revision order to all watchers, ensuring controllers always see a consistent, ordered history of changes.
