Remote sessions can send their events over a continuous stream when the server offers one

Cloud session workers can now accept a server offer to send events over a streaming connection, alongside the usual one-request-per-batch route

What

A remote session's worker reports what is happening (its events) to the server. Until now it only did so by sending each batch of events as a separate request. It can now also send them over a continuous streaming connection, when the server offers one. The offer can come in the reply the worker receives at startup, or in its regular check-ins with the server.

Along with this:

  • the worker sends a count of how many times the stream has broken
  • its requests use their own set of network connections, kept apart from the rest of Claude Code

This applies when the process manages itself and is either not hosted, or is hosted in Anthropic's cloud.

Why

This changes how events from a remote session reach the server, and what happens when the stream drops partway through. Nothing changes until the server starts sending offers.
