Unclear What noting a draining host or the denial handling changes for a session is not clear.

What

Some tools can run in a remote container, an isolated machine somewhere else. When that container's host reports it is draining, meaning it is shutting down and taking no new work, Claude Code now notes it. A host reports this through a response header set to 1. Two kinds of denial are now handled with this in mind: results the server is no longer holding, and calls that are unavailable because they were cut short.

Why

Remote tool sessions can now take into account that their host is going away.
