DiffViewer refactor — 6-section plugin pattern + 1000-row cap. Closes task #156 (Phase 6.4 Stream C). Replaces the flat single-table rendering that mixed Namespace/DriverInstance/Equipment/Tag rows into one untyped list with a per-section-card layout that makes draft review actually scannable on non-trivial diffs. New DiffSection.razor reusable component encapsulates the per-section rendering — card header shows Title + Description + a three-badge summary (+added / −removed / ~modified plus a "no changes" grey badge when the section is empty) so operators can glance at a six-card page and see what areas of the draft actually shifted before drilling into any one table. Hard row-cap at DefaultRowCap=1000 per section lives inside the component so a pathological draft (e.g. 20k tags churned by a block rebuild) can't freeze the browser on render — excess rows are silently dropped with a yellow warning banner that surfaces "Showing the first 1000 of N rows" + a pointer to run sp_ComputeGenerationDiff directly for the full set. Body max-height: 400px + overflow-y: auto gives each section its own scroll region so one big section doesn't push the others off screen. DiffViewer.razor refactored to a static Sections table driving a single foreach that instantiates one DiffSection per known TableName. Sections listed in author-order (Namespace → DriverInstance → Equipment → Tag → UnsLine → NodeAcl) — six entries matching the task acceptance criterion. The first four correspond to what sp_ComputeGenerationDiff currently emits; the last two (UnsLine + NodeAcl) render as empty "no changes" cards today + will light up when the proc is extended (tracked in task #196 for NodeAcl; UnsLine proc extension is a natural follow-up since UnsImpactAnalyzer already tracks UNS moves). RowsFor(tableName) replaces the prior flat table — each section filters the overall DiffRow list by its TableName so the proc output format stays stable. Header-bar summary at the top of the page now reads "N rows across M of 6 sections" so operators see overall change weight at a glance before scanning. Two Razor-specific fixes landed along the way: loop variable renamed from section to sec because @section collides with the Razor section directive + trips RZ2005; helper method renamed from Group to RowsFor because the Razor generator gets confused by a parameter-flowing method whose name clashes with LINQ's Group extension (the source-gen output referenced TypeCheck<T> with no argument). Admin project builds 0 errors; Admin.Tests suite 76/76 (unchanged — the refactor is structural + no service-layer logic changed, so the existing DraftValidator + EquipmentService + AdminServicesIntegrationTests cover the consuming paths). No bUnit in this project so the cap behavior isn't unit-tested at the component level; DiffSection.OnParametersSet is small + deterministic (int counts + Take(RowCap)) + reviewed before ship.

Phase 3 PR 27 — Fleet status dashboard page. New /fleet route shows per-node apply state (ClusterNodeGenerationState joined with ClusterNode for the ClusterId) in a sortable table with summary cards for Total / Applied / Stale / Failed node counts. Stale detection: LastSeenAt older than 30s triggers a table-warning row class + yellow count card. Failed rows get table-danger + red card. Badge classes per LastAppliedStatus: Applied=bg-success, Failed=bg-danger, Applying=bg-info, unknown=bg-secondary. Timestamps rendered as relative-age strings ('42s ago', '15m ago', '3h ago', then absolute date for >24h). Error column is truncated to 320px with the full message in a tooltip so the table stays readable on wide fleets. Initial data load on OnInitializedAsync; auto-refresh every 5s via a Timer that calls InvokeAsync(RefreshAsync) — matches the FleetStatusPoller's 5s cadence so the dashboard sees the most recent state without polling ahead of the broadcaster. A Refresh button also kicks a manual reload; _refreshing gate prevents double-runs when the timer fires during an in-flight query. IServiceScopeFactory (matches FleetStatusPoller's pattern) creates a fresh DI scope per refresh so the per-page DbContext can't race the timer with the render thread; no new DI registrations needed. Live SignalR hub push is deliberately deferred to a follow-up PR — the existing FleetStatusHub + NodeStateChangedMessage already works for external JavaScript clients; wiring an in-process Blazor Server consumer adds HubConnectionBuilder plumbing that's worth its own focused change. Sidebar link added to MainLayout between Overview and Clusters. Full Admin.Tests Unit suite 14 pass / 0 fail — unchanged, no tests regressed. Full Admin build clean (0 errors, 0 warnings). Closes the 'no per-driver dashboard' gap from lmx-followups item #7 at the fleet level; per-host (platform/engine/Modbus PLC) granularity still needs a dedicated page that consumes IHostConnectivityProbe.GetHostStatuses from the Server process — that's the live-SignalR follow-up.
Phase 1 Stream E Admin UI — finish Blazor pages so operators can run the draft → publish → rollback workflow end-to-end without hand-executing SQL. Adds eight new scoped services that wrap the Configuration stored procs + managed validators: EquipmentService (CRUD with auto-derived EquipmentId per decision #125), UnsService (areas + lines), NamespaceService, DriverInstanceService (generic JSON DriverConfig editor per decision #94 — per-driver schema validation lands in each driver's phase), NodeAclService (grant + revoke with bundled-preset permission sets; full per-flag editor + bulk-grant + permission simulator deferred to v2.1), ReservationService (fleet-wide active + released reservation inspector + FleetAdmin-only sp_ReleaseExternalIdReservation wrapper with required-reason invariant), DraftValidationService (hydrates a DraftSnapshot from the draft's rows plus prior-cluster Equipment + active reservations, runs the managed DraftValidator to surface every rule in one pass for inline validation panel), AuditLogService (recent ConfigAuditLog reader). Pages: /clusters list with create-new shortcut; /clusters/new wizard that creates the cluster row + initial empty draft in one go; /clusters/{id} detail with 8 tabs (Overview / Generations / Equipment / UNS Structure / Namespaces / Drivers / ACLs / Audit) — tabs that write always target the active draft, published generations stay read-only; /clusters/{id}/draft/{gen} editor with live validation panel (errors list with stable code + message + context; publish button disabled while any error exists) and tab-embedded sub-components; /clusters/{id}/draft/{gen}/diff three-column view backed by sp_ComputeGenerationDiff with Added/Removed/Modified badges; Generations tab with per-row rollback action wired to sp_RollbackToGeneration; /reservations FleetAdmin-only page (CanPublish policy) with active + released lists and a modal release dialog that enforces non-empty reason and round-trips through sp_ReleaseExternalIdReservation; /login scaffold with stub credential accept + FleetAdmin-role cookie issuance (real LDAP bind via the ScadaLink-parity LdapAuthService is deferred until live GLAuth integration — marked in the login view and in the Phase 1 partial-exit TODO). Layout: sidebar gets Overview / Clusters / Reservations + AuthorizeView with signed-in username + roles + sign-out POST to /auth/logout; cascading authentication state registered for <AuthorizeView> to work in RenderMode.InteractiveServer. Integration testing: AdminServicesIntegrationTests creates a throwaway per-run database (same pattern as the Configuration test fixture), applies all three migrations, and exercises (1) create-cluster → add-namespace+UNS+driver+equipment → validate (expects zero errors) → publish (expects Published status) → rollback (expects one new Published + at least one Superseded); (2) cross-cluster namespace binding draft → validates to BadCrossClusterNamespaceBinding per decision #122. Old flat Components/Pages/Clusters.razor moved to Components/Pages/Clusters/ClustersList.razor so the Clusters folder can host tab sub-components without the razor generator creating a type-and-namespace collision. Dev appsettings.json connection string switched from Integrated Security to sa auth to match the otopcua-mssql container on port 14330 (remapped from 1433 to coexist with the native MSSQL14 Galaxy ZB instance). Browser smoke test completed: home page, clusters list, new-cluster form, cluster detail with a seeded row, reservations (redirected to login for anon user) all return 200 / 302-to-login as expected; full solution 928 pass / 1 pre-existing Phase 0 baseline failure. Phase 1 Stream E items explicitly deferred with TODOs: CSV import for Equipment, SignalR FleetStatusHub + AlertHub real-time push, bulk-grant workflow, permission-simulator trie, merge-equipment draft, AppServer-via-OI-Gateway end-to-end smoke test (decision #142), and the real LDAP bind replacing the Login page stub.
Admin /hosts red-badge + resilience columns + Polly telemetry observer. Closes task #164 (the remaining slice of Phase 6.1 Stream E.3 after the earlier publisher + hub PR). Three cooperating pieces wired together so the operator-facing /hosts table actually reflects the live Polly counters that the pipeline builder is producing. DriverResiliencePipelineBuilder gains an optional DriverResilienceStatusTracker ctor param — when non-null, every built pipeline wires Polly's OnRetry/OnOpened/OnClosed strategy-options callbacks into the tracker. OnRetry → tracker.RecordFailure (so ConsecutiveFailures climbs per retry), OnOpened → tracker.RecordBreakerOpen (stamps LastCircuitBreakerOpenUtc), OnClosed → tracker.RecordSuccess (resets the failure counter once the target recovers). Absent tracker = silent, preserving the unit-test constructor path + any deployment that doesn't care about resilience observability. Cancellation stays excluded from the failure count via the existing ShouldHandle predicate. HostStatusService.HostStatusRow extends with four new fields — ConsecutiveFailures, LastCircuitBreakerOpenUtc, CurrentBulkheadDepth, LastRecycleUtc — populated via a second LEFT JOIN onto DriverInstanceResilienceStatuses keyed on (DriverInstanceId, HostName). LEFT JOIN because brand-new hosts haven't been sampled yet; a missing row means zero failures + never-opened breaker, which is the correct default. New FailureFlagThreshold constant (=3, matches plan decision #143's conservative half-of-breaker convention) + IsFlagged predicate so the UI can pre-warn before the breaker actually trips. Hosts.razor paints three new columns between State and Last-transition — Fail# (bold red when flagged), In-flight (bulkhead-depth proxy), Breaker-opened (relative age). Per-row "Flagged" red badge alongside State when IsFlagged is true. Above the first cluster table, a red alert banner summarises the flagged-host count when ≥1 host is flagged, so operators see the problem before scanning rows. Three new tests in DriverResiliencePipelineBuilderTests — Tracker_RecordsFailure_OnEveryRetry verifies ConsecutiveFailures reaches RetryCount after a transient-forever operation, Tracker_StampsBreakerOpen_WhenBreakerTrips verifies LastBreakerOpenUtc is set after threshold failures on a Write pipeline, Tracker_IsolatesCounters_PerHost verifies one dead host does not leak failure counts into a healthy sibling. Full suite — Core.Tests 14/14 resilience-builder tests passing (11 existing + 3 new), Admin.Tests 72/72 passing, Admin project builds 0 errors. SignalR live push of status changes + browser visual review are deliberately left to a follow-up — this PR keeps the structural change minimal (polling refresh already exists in the page's 10s timer; SignalR would be a structural add that touches hub registration + client subscription).
Phase 1 Stream E Admin UI — finish Blazor pages so operators can run the draft → publish → rollback workflow end-to-end without hand-executing SQL. Adds eight new scoped services that wrap the Configuration stored procs + managed validators: EquipmentService (CRUD with auto-derived EquipmentId per decision #125), UnsService (areas + lines), NamespaceService, DriverInstanceService (generic JSON DriverConfig editor per decision #94 — per-driver schema validation lands in each driver's phase), NodeAclService (grant + revoke with bundled-preset permission sets; full per-flag editor + bulk-grant + permission simulator deferred to v2.1), ReservationService (fleet-wide active + released reservation inspector + FleetAdmin-only sp_ReleaseExternalIdReservation wrapper with required-reason invariant), DraftValidationService (hydrates a DraftSnapshot from the draft's rows plus prior-cluster Equipment + active reservations, runs the managed DraftValidator to surface every rule in one pass for inline validation panel), AuditLogService (recent ConfigAuditLog reader).

Layout: sidebar gets Overview / Clusters / Reservations + AuthorizeView with signed-in username + roles + sign-out POST to /auth/logout; cascading authentication state registered for <AuthorizeView> to work in RenderMode.InteractiveServer. Integration testing: AdminServicesIntegrationTests creates a throwaway per-run database (same pattern as the Configuration test fixture), applies all three migrations, and exercises (1) create-cluster → add-namespace+UNS+driver+equipment → validate (expects zero errors) → publish (expects Published status) → rollback (expects one new Published + at least one Superseded); (2) cross-cluster namespace binding draft → validates to BadCrossClusterNamespaceBinding per decision #122. Old flat Components/Pages/Clusters.razor moved to Components/Pages/Clusters/ClustersList.razor so the Clusters folder can host tab sub-components without the razor generator creating a type-and-namespace collision. Dev appsettings.json connection string switched from Integrated Security to sa auth to match the otopcua-mssql container on port 14330 (remapped from 1433 to coexist with the native MSSQL14 Galaxy ZB instance).

Admin RoleGrants page — LDAP-group → Admin-role mapping CRUD. Closes the RoleGrantsTab slice of task #144 (Phase 6.2 Stream D follow-up); the remaining three sub-items (Probe-this-permission on AclsTab, SignalR invalidation on role/ACL changes, draft-diff ACL section) are split into new follow-up task #196 so each can ship independently. The permission-trie evaluator + ILdapGroupRoleMappingService already exist from Phase 6.2 Streams A + B — this PR adds the consuming UI + the DI registration that was missing. New /role-grants page at Components/Pages/RoleGrants.razor registered in MainLayout's sidebar next to Certificates. Lists every LdapGroupRoleMapping row with columns LDAP group / Role / Scope (Fleet-wide or Cluster:X) / Created / Notes / Revoke. Add-grant form takes LDAP group DN + AdminRole dropdown (ConfigViewer, ConfigEditor, FleetAdmin) + Fleet-wide checkbox + Cluster dropdown (disabled when Fleet-wide checked) + optional Notes. Service-layer invariants — IsSystemWide=true + ClusterId=null, or IsSystemWide=false + ClusterId populated — enforced in ValidateInvariants; UI catches InvalidLdapGroupRoleMappingException and displays the message in a red alert. ILdapGroupRoleMappingService was present in the Configuration project from Stream A but never registered in the Admin DI container — this PR adds the AddScoped registration so the injection can resolve. Control-plane/data-plane separation note rendered in an info banner at the top of the page per decision #150 (these grants do NOT govern OPC UA data-path authorization; NodeAcl rows are read directly by the permission-trie evaluator without consulting role mappings). Admin project builds 0 errors; Admin.Tests 72/72 passing. Task #196 created to track: (1) AclsTab Probe-this-permission form that takes (ldap group, node path, permission flag) and runs it through the permission trie, showing which row granted it + the actual resolved grant; (2) SignalR invalidation — push a RoleGrantsChanged event when rows are created/deleted so connected Admin sessions reload without polling, ditto NodeAclChanged on ACL writes; (3) DiffViewer ACL section — show NodeAcl + LdapGroupRoleMapping deltas between draft + published alongside equipment/uns diffs.
