 ## Unreleased
 
+- `InvocationList.detachedEnabled`: whether the operator enabled
+  detached invocations — monitor UIs can distinguish "feature off"
+  from "on, but no runs yet". Regenerated stubs.
+
 - `planSetup()`: guided-setup plan preview over the hub connection
   (the new `PlanSetup` HubAdmin RPC) — returns the assembled plan
   (scenario, steps, config keys) without spawning the `chain` CLI.
