Bun.serve defaults to a 10-second idle timeout. Claude Agent SDK turns routinely take longer than that — a cold start alone can spend more, between spawning the CLI and the model's first token — so the connection is dropped mid-turn. The failure is quiet from the host's side: the request ends without an error the caller can attribute to a timeout, which makes it look like the turn simply died. 255s is Bun's maximum for this option.

That made it hard to spot; I only found it after patching the installed
dist/by hand and watching long turns stop failing.255s is Bun's maximum for this option.
Three lines, no behaviour change other than the timeout.
