Phase 3 PR 34 — Host-status publisher (Server) + /hosts drill-down page (Admin). Closes LMX follow-up #7 by wiring together the data layer from PR 33. Server.HostStatusPublisher is a BackgroundService that walks every driver registered in DriverHost every 10 seconds, skips drivers that don't implement IHostConnectivityProbe, calls GetHostStatuses() on each probe-capable driver, and upserts one DriverHostStatus row per (NodeId, DriverInstanceId, HostName) into the central config DB. Upsert path: SingleOrDefaultAsync on the composite PK; if no row exists, Add a new one; if a row exists, LastSeenUtc advances unconditionally (heartbeat) and State + StateChangedUtc update only on transitions so Admin UI can distinguish 'still reporting, still Running' from 'freshly transitioned to Running'. MapState translates Core.Abstractions.HostState to Configuration.Enums.DriverHostState (intentional duplicate enum — Configuration project stays free of driver-runtime deps per PR 33's choice). If a driver's GetHostStatuses throws, log warning and skip that driver this tick — never take down the Server on a publisher failure. If the DB is unreachable, log warning + retry next heartbeat (no buffering — next tick's current-state snapshot is more useful than replaying stale transitions after a long outage). 2-second startup delay so NodeBootstrap's RegisterAsync calls land before the first publish tick, then tick runs immediately so a freshly-started Server surfaces its host topology in the Admin UI without waiting a full interval.

Hubs

Phase 1 LDAP auth + SignalR real-time — closes the last two open Admin UI TODOs. LDAP: Admin/Security/ gets SecurityOptions (bound from appsettings.json Authentication:Ldap), LdapAuthResult record, ILdapAuthService + LdapAuthService ported from scadalink-design's LdapAuthService (TLS guard, search-then-bind when a service account is configured, direct-bind fallback, service-account re-bind after user bind so attribute lookup uses the service principal's read rights, LdapException-to-friendly-message translation, OperationCanceledException pass-through), RoleMapper (pure function: case-insensitive group-name match against LdapOptions.GroupToRole, returns the distinct set of mapped Admin roles). EscapeLdapFilter escapes the five LDAP filter control chars (\, *, (, ), \0); ExtractFirstRdnValue pulls the value portion of a DN's leading RDN for memberOf parsing; ExtractOuSegment added as a GLAuth-specific fallback when the directory doesn't populate memberOf but does embed ou=PrimaryGroup into user DNs (actual GLAuth config in C:\publish\glauth\glauth.cfg uses nameformat=cn, groupformat=ou — direct bind is enough). Login page rewritten: EditForm → ILdapAuthService.AuthenticateAsync → cookie sign-in with claims (Name = displayName, NameIdentifier = username, Role for each mapped role, ldap_group for each raw group); failed bind shows the service's error; empty-role-map returns an explicit "no Admin role mapped" message rather than silently succeeding. appsettings.json gains an Authentication:Ldap section with dev-GLAuth defaults (localhost:3893, UseTls=false, AllowInsecureLdap=true for dev, GroupToRole maps GLAuth's ReadOnly/WriteOperate/AlarmAck → ConfigViewer/ConfigEditor/FleetAdmin). SignalR: two hubs + a BackgroundService poller. FleetStatusHub routes per-cluster NodeStateChanged pushes (SubscribeCluster/UnsubscribeCluster on connection; FleetGroup for dashboard-wide) with a typed NodeStateChangedMessage payload. AlertHub auto-subscribes every connection to the AllAlertsGroup and exposes AcknowledgeAsync (ack persistence deferred to v2.1). FleetStatusPoller (IHostedService, 5s default cadence) scans ClusterNodeGenerationState joined with ClusterNode, caches the prior snapshot per NodeId, pushes NodeStateChanged on any delta, raises AlertMessage("apply-failed") on transition INTO Failed (sticky — the hub client acks later). Program.cs registers HttpContextAccessor (sign-in needs it), SignalR, LdapOptions + ILdapAuthService, the poller as hosted service, and maps /hubs/fleet + /hubs/alerts endpoints. ClusterDetail adds @rendermode RenderMode.InteractiveServer, @implements IAsyncDisposable, and a HubConnectionBuilder subscription that calls LoadAsync() on each NodeStateChanged for its cluster so the "current published" card refreshes without a page reload; a dismissable "Live update" info banner surfaces the most recent event. Microsoft.AspNetCore.SignalR.Client 10.0.0 + Novell.Directory.Ldap.NETStandard 3.6.0 added. Tests: 13 new — RoleMapperTests (single group, case-insensitive match, multi-group distinct-roles, unknown-group ignored, empty-map); LdapAuthServiceTests (EscapeLdapFilter with 4 inputs, ExtractFirstRdnValue with 4 inputs — all via reflection against internals); LdapLiveBindTests (skip when localhost:3893 unreachable; valid-credentials-bind-succeeds; wrong-password-fails-with-recognizable-error; empty-username-rejected-before-hitting-directory); FleetStatusPollerTests (throwaway DB, seeds cluster+node+generation+apply-state, runs PollOnceAsync, asserts NodeStateChanged hit the recorder; second test seeds a Failed state and asserts AlertRaised fired) — backed by RecordingHubContext/RecordingHubClients/RecordingClientProxy that capture SendCoreAsync invocations while throwing NotImplementedException for the IHubClients methods the poller doesn't call (fail-fast if evolution adds new dependencies). InternalsVisibleTo added so the test project can call FleetStatusPoller.PollOnceAsync directly. Full solution 946 pass / 1 pre-existing Phase 0 baseline failure.

Phase 1 Streams B–E scaffold + Phase 2 Streams A–C scaffold — 8 new projects with ~70 new tests, all green alongside the 494 v1 IntegrationTests baseline (parity preserved: no v1 tests broken; legacy OtOpcUa.Host untouched). Phase 1 finish: Configuration project (16 entities + 10 enums + DbContext + DesignTimeDbContextFactory + InitialSchema/StoredProcedures/AuthorizationGrants migrations — 8 procs including sp_PublishGeneration with MERGE on ExternalIdReservation per decision #124 , sp_RollbackToGeneration cloning rows into a new published generation, sp_ValidateDraft with cross-cluster-namespace + EquipmentUuid-immutability + ZTag/SAPID reservation pre-flight, sp_ComputeGenerationDiff with CHECKSUM-based row signature — plus OtOpcUaNode/OtOpcUaAdmin SQL roles with EXECUTE grants scoped to per-principal-class proc sets and DENY UPDATE/DELETE/INSERT/SELECT on dbo schema); managed DraftValidator covering UNS segment regex, path length, EquipmentUuid immutability across generations, same-cluster namespace binding (decision #122 ), reservation pre-flight, EquipmentId derivation (decision #125 ), driver↔namespace compatibility — returning every failing rule in one pass; LiteDB local cache with round-trip + ring pruning + corruption-fast-fail; GenerationApplier with per-entity Added/Removed/Modified diff and dependency-ordered callbacks (namespace → driver → device → equipment → poll-group → tag, Removed before Added); Core project with GenericDriverNodeManager (scaffold for the Phase 2 Galaxy port) and DriverHost lifecycle registry; Server project using Microsoft.Extensions.Hosting BackgroundService replacing TopShelf, with NodeBootstrap that falls back to LiteDB cache when the central DB is unreachable (decision #79 ); Admin project scaffolded as Blazor Server with Bootstrap 5 sidebar layout, cookie auth, three admin roles (ConfigViewer/ConfigEditor/FleetAdmin), Cluster + Generation services fronting the stored procs.
