Under the hood

Cloud sessions now reconcile server-sent messages and wait for pending tool calls to settle before proceeding.

What

The part of Claude Code that talks to cloud-hosted sessions (sessions running remotely rather than on your machine) now reconciles messages attached by the server against what it already has, matching them by id, version and text instead of trusting a simple policy label as before. When acting as the coordinator for a cloud session, it also waits up to a fixed timeout for tool calls that are still in flight or pending to settle before moving on, rather than proceeding immediately.

Why

This should reduce cases where a cloud session's view of the conversation gets out of sync with the server, or where the coordinator moves ahead while a tool call is still resolving.
