Not a page we edit when something changes. This asks the running system which modules are live, which are in shadow, and which are on standby — every time you load it. If the answer can't be read, it says so rather than showing you a green tick.
Running, and allowed to act — including messaging real customers where that's the module's job.
Running and computing, but not allowed to send. It logs exactly what it would have done and a human reads it. Every agent starts here.
Built and deployed, switch off. Nothing runs, nothing sends. A missing switch reads as standby — never as live.
