What
When Claude Code binds a session to a device, it checks whether the environment is eligible. There's now a new refusal reason, environment, that is returned when the session's environment is byoc (bring-your-own-cloud) or bridge instead of Anthropic's own cloud. This joins the existing refusal reasons endpoint, pool, and correlation. The check is applied both when device-binder enrollment is prepared (which also now forwards a confirmReenroll flag) and when a cloud session is bound to a device, and it feeds into the same reason table used to show the failure message to the user, with a matching telemetry event.
Why
This makes it clear to users and to Claude Code's own logic why a device-binding attempt failed when the session isn't running on Anthropic's own cloud infrastructure, rather than lumping it in with unrelated binding failures.
