DriverHostState enum lives in Configuration.Enums/ rather than reusing Core.Abstractions.HostState so the Configuration project stays free of driver-runtime dependencies (it's referenced by both the Admin process and the Server process, so pulling in the driver-abstractions assembly to every Admin build would be unnecessary weight). The server-side publisher hosted service (follow-up PR 34) will translate HostStatusChangedEventArgs.NewState to this enum on every transition. No foreign key to ClusterNode — a Server may start reporting host status before its ClusterNode row exists (first-boot bootstrap), and we'd rather keep the status row than drop it. The Admin-side service that renders the dashboard will left-join on NodeId when presenting. Two indexes declared: IX_DriverHostStatus_Node drives the per-cluster drill-down (Admin UI joins ClusterNode on ClusterId to pick which NodeIds to fetch), IX_DriverHostStatus_LastSeen drives the stale-row query (now - LastSeen > threshold). EF migration AddDriverHostStatus creates the table + PK + both indexes. Model snapshot updated. SchemaComplianceTests expected-tables list extended. DriverHostStatusTests (3 new cases, category SchemaCompliance, uses the shared fixture DB): composite key allows same (host, driver) across different nodes AND same (node, host) across different drivers — both real-world cases the publisher needs to support; upsert-in-place pattern (fetch-by-composite-PK, mutate, save) produces one row not two — the pattern the publisher will use; State enum persists as string not int — reading the DB via ADO.NET returns 'Faulted' not '3'. Configuration.Tests SchemaCompliance suite: 10 pass / 0 fail (7 prior + 3 new). Configuration build clean. No Server or Admin code changes yet — publisher + /hosts page are PR 34.
