Long-lived session state can now be watched, likely plumbing for a status indicator.
A session-state subscription emits armed and off states but nothing user-visible consumes it.
What's wrong with this entry?
The registry that tracks long-lived sessions gained a way to subscribe to a session's state, polling and emitting normalized values such as an armed state naming the engine and direction, or an off state naming the reason. It also counts when a session's full listing grows past its allowed size. Nothing user-visible consumes it yet; it looks like plumbing for a status indicator.
- The polling interval is set by an internal constant whose value is not visible in the build.
