Remote-bridge REPL sessions gain hooks for forking a conversation and checking for pending prompts
The session builder used for remote and headless REPL sessions (the Remote Control v2 transport handler) now passes two new items into each connection's configuration: an onForkConversation callback, and a hasPendingPrompts() function that reports whether there are prompts still waiting to be handled. These sit alongside the existing onMcpSetServers, outboundOnly, and writeFrame fields.
The finding doesn't say what calls these new hooks or what user-facing feature they support, only that the plumbing for forking a conversation and checking pending-prompt state is now in place for remote sessions.
What feature uses these hooks, and what effect they have for someone using Remote Control, isn't established by the evidence.
