 **Resolution**
 
-_Unresolved._
+Resolved 2026-11-09 in the commit tagged `(scadaproj#48)` (Health `0.3.1`, unpublished) — added `AkkaActiveNodeGate.ForOptions(sp, ActiveNodeHealthCheckOptions)` and a shared `ClusterActiveNode.SelfIsActiveForPreference(cluster, rolePreference)` (resolve the first preferred role the node carries, then `SelfIsActive`; a node with none of the roles is never active), so the gate and `/health/active` share one scope definition. Chose a static factory over a second public constructor so an existing `new AkkaActiveNodeGate(sp, null)` call is not made ambiguous. Class remarks qualified. Tests `Gate_ForOptions_AgreesWithTheProbeOnEveryNode_ForAMultiRolePreference` and `..._NodeCarryingNoPreferredRole_IsNeverActive_AndEmptyPreferenceIsUnscoped` (new API, so they cannot compile without the fix).
