fix(adminui): wire Test Connect probes + live panels on admin-only nodes

Both bugs surfaced only on split-role deployments (the MAIN cluster's admin-only nodes), where the AdminUI runs without the driver role. - Test Connect returned "No probe registered" for every driver: the IDriverProbe set was registered only under the driver role, but the admin-operations singleton that consumes it is pinned to admin. Extract AddOtOpcUaDriverProbes() (idempotent via TryAddEnumerable) and call it in the hasAdmin path too. - Live driver-status/alerts/script-log panels showed "SignalR error: Connection refused": these Blazor Server components opened a HubConnection to their own hub via the browser's public URL, which server-side code can't reach behind Traefik (host :9200 -> container :9000). Read the in-process source directly instead -- DriverStatus via IDriverStatusSnapshotStore.SnapshotChanged, Alerts/ScriptLog via a new IInProcessBroadcaster<T>. Fleet status was unaffected (reads DB/ActorSystem). Adds unit tests for probe registration, the snapshot-store event, and the broadcaster.

+# Design — Complete AdminUI deferred follow-ups
+
+**Date:** 2026-05-29
+**Status:** Approved (design); implementation plan to follow
+**Author:** Joseph Doherty (with Claude Code)
+
+## Background
+
+The AdminUI carried a family of "deferred / Phase C.2 follow-up" notes. A prior
+change stripped the stale *rendered roadmap banners* from the cluster list pages.
+Three remaining note groups were investigated to decide what real work they hide:
+
+- **Group 1 — driver-page inline notes** ("list-editor coming in a follow-up
+  phase" for tags/devices/endpoints; "typed-form-ifying Polly is a follow-up").
+  → **Real pending UI work.**
+- **Group 2 — RoleGrants** ("UI-driven editing of the mapping is deferred — it
+  implies a config-reload mechanism that doesn't exist yet"). → **Real work; half
+  the infra already exists.**
+- **Group 3 — source comments** (F15 Razor migration, F16 FleetStatusHub bridge,
+  "Phase 4" identity section, `TODO(3.3/3.4)` route collision). → **~90% stale**;
+  the referenced work already shipped (the F16 bridge is wired; the legacy
+  `DriverEdit.razor` no longer exists). Only the Polly typed form is real, and it
+  is already counted in Group 1.
+
+### Key facts established during exploration
+
+- **Driver-embedded tag/device lists in `DriverConfig` JSON are the runtime source
+  of truth.** Driver factories deserialize them and poll exactly those rows; the
+  canonical `Tag` table is orthogonal (OPC UA browse-tree only, never read by
+  drivers). So inline editors are meaningful, not redundant — editing them changes
+  what the driver polls on the next publish/reinitialize.
+- **Resilience** already has a strongly-typed model: `DriverResilienceOptions`
+  (`BulkheadMaxConcurrent`, `BulkheadMaxQueue`, `RecycleIntervalSeconds`,
+  `CapabilityPolicies: {DriverCapability → (TimeoutSeconds, RetryCount,
+  BreakerFailureThreshold)}`) with tier A/B/C defaults via `GetTierDefaults(tier)`
+  and a `DriverResilienceOptionsParser`. The stored JSON is an *override* shape;
+  null/absent keys fall back to tier defaults.
+- **LDAP role map**: the `LdapGroupRoleMapping` entity + migration +
+  `ILdapGroupRoleMappingService` (CRUD) already exist but are **not wired** into
+  login. `LdapAuthService` still reads the static appsettings `GroupToRole`
+  (`Dictionary<string,string>`). `RoleGrants.razor` is read-only.
+- **Testing**: no bUnit. Established pattern = test `FromOptions`/`ToOptions`
+  round-trips (xUnit + Shouldly in `AdminUI.Tests`) and services with in-memory EF
+  (`Configuration.Tests`).
+
+## Decisions
+
+- **Scope:** full build — all real follow-ups in Groups 1 & 2, plus Group 3
+  comment cleanup.
+- **List-editor UX:** modal-per-row with a shared shell component.
+- **LDAP reload semantics:** DB-backed, **live on the user's next sign-in**
+  (per-login DB query; no restart, no new infra). appsettings `GroupToRole` becomes
+  a bootstrap **fallback** layer.
+- **Roles are GLOBAL.** No cluster-level permissions / no per-cluster enforcement
+  (explicitly chosen for simplicity, reversing an earlier cluster-scoping answer).
+  Every `LdapGroupRoleMapping` row is `IsSystemWide=true`, `ClusterId=null`.
+
+## Workstreams
+
+### WS1 — Driver collection editors (modal-per-row + shared shell)
+
+- New generic `CollectionEditor<TRow>` component in `Components/Shared/Drivers/`:
+  compact read-only table + `[+ Add]` / per-row `Edit` / `Delete`, and a Bootstrap
+  modal editing a **working copy** of a row (commit on modal-Save, discard on
+  Cancel). Parameters: `List<TRow> Items` (bound), header fragment, read-only-cells
+  fragment, modal-body fragment, `NewRow` factory, optional `Validate` delegate.
+- Each driver page swaps its read-only `<pre>` for a `CollectionEditor` supplying
+  its own columns + modal fields. Edits mutate the in-memory `List<T>` already in
+  the page's `FormModel`; the page's existing **Save** serializes it into
+  `DriverConfig` — no new persistence path.
+- Coverage: tags (Modbus, AbCip, AbLegacy, TwinCAT, S7, FOCAS); devices (AbCip,
+  AbLegacy, TwinCAT, FOCAS); endpoints (OpcUaClient).
+- **Errors/validation:** required fields, duplicate Name within list,
+  driver-specific address format; delete confirm; list mutates only on valid commit.
+- **Testing:** per-driver `NewRow` factories + `Validate` methods unit-tested
+  directly; existing `*FormSerializationTests` extended for add/remove via the form
+  model. Modal interaction verified manually via `/run`.
+
+### WS2 — Resilience typed form
+
+- Replace the textarea in `DriverResilienceSection.razor` with a typed form bound to
+  a new mutable `ResilienceFormModel` (all fields nullable; null = tier default):
+  bulkhead concurrent/queue, recycle interval, and an 8-capability grid (Read,
+  Write, Discover, Subscribe, Probe, AlarmSubscribe, AlarmAcknowledge, HistoryRead)
+  of (timeout / retry / breaker-threshold).
+- `FromJson`/`ToJson` emit only non-null overrides (blank → `null`, preserving the
+  current "null = tier defaults" contract). The section gains a `DriverTier`
+  parameter; each driver page passes its known tier so `GetTierDefaults(tier)`
+  renders as placeholders. A collapsible "raw JSON" view remains as escape hatch.
+- **Errors:** non-negative / sane-range numeric validation; emitted JSON must
+  re-parse cleanly through `DriverResilienceOptionsParser`.
+- **Testing:** `ResilienceFormModel` round-trip tests in `AdminUI.Tests` —
+  blank→null, partial-override-preserved, emit→parse-back compatibility.
+
+### WS3 — Editable LDAP→role map (DB-backed, global, live on next sign-in)
+
+- `RoleGrants.razor` → full CRUD over `LdapGroupRoleMapping` via the existing
+  `ILdapGroupRoleMappingService`. **Global only**: `IsSystemWide=true`,
+  `ClusterId=null`; no cluster UI. Fields: LDAP group, `AdminRole`
+  (ConfigViewer/ConfigEditor/FleetAdmin), notes. A group may carry several roles
+  (multiple rows). Edit page gated to **FleetAdmin** (add a minimal FleetAdmin
+  authorization policy; confirm existing role-policy plumbing during plan-writing).
+- Wire the service into `LdapAuthService`: at login → resolve groups →
+  `GetByGroupsAsync` (indexed) → map roles → **merge appsettings `GroupToRole` as a
+  fallback layer** (used when no DB row covers a group). Edits take effect on the
+  user's next sign-in. DB rows authoritative + editable; appsettings entries shown
+  read-only as "fallback."
+- **Errors:** DB unreachable at login → catch, log, fall back to appsettings;
+  login never blocks. CRUD: no duplicate `(LdapGroup, Role)`; group/role required.
+- **Testing:** extend `LdapGroupRoleMappingServiceTests` (in-memory EF) for CRUD +
+  dedupe; new `RoleMapper` overload `Map(groups, dbRows, fallbackDict)` unit-tested
+  for merge + fallback precedence + DB-error fallback.
+
+### WS4 — Cleanup (runs last, after the features exist)
+
+- **Delete stale comments:** `FleetStatusHub.cs` ("passive channel / until the
+  bridge lands"), `EndpointRouteBuilderExtensions.cs` (F15), `DriverIdentitySection.razor`
+  ("Phase 4 / generic DriverEdit"), `DriverEditRouter.razor` + `DriverTypePicker.razor`
+  (`TODO(3.3/3.4)` + the "falls back to legacy DriverEdit" path — verify & clean,
+  legacy file is gone), and update `DriverResilienceSection.razor`'s comment.
+- **Strip rendered notes** now true: per-driver "list-editor coming in a follow-up
+  phase" notes, the OpcUaClient endpoint note, the resilience "typed-form-ifying
+  Polly is a follow-up" note, and the RoleGrants "UI-driven editing is deferred" note.
+
+## Cross-cutting
+
+- **No DB schema change** — `LdapGroupRoleMapping` migration already applied;
+  `DriverConfig`/`ResilienceConfig` columns unchanged.
+- **Definition of done:** build clean + `dotnet test` green + a `/run` pass
+  exercising the modal editors and role-map CRUD.
+- **Suggested sequence:** WS1 shared shell + Modbus tags as proof → remaining
+  drivers → WS2 → WS3 → WS4.

+# Auth/login alignment with ScadaBridge — design
+
+> **Status:** approved 2026-05-29. Implementation plan to follow via `writing-plans`.
+> **Trigger:** browser hitting `http://localhost:9200/` rendered Chrome's `HTTP_RESPONSE_CODE_FAILURE` page because the cookie scheme's `OnRedirectToLogin` event was overridden to return 401 with no body, and the parallel JwtBearer scheme stamped `WWW-Authenticate: Bearer`. ScadaBridge sets `LoginPath` and lets the framework do its built-in browser-vs-AJAX heuristic; OtOpcUa diverged.
+
+**Goal:** Restore default browser-redirect ergonomics on protected GETs, retire the unused JwtBearer server-side scheme, and externalize cookie config — bringing OtOpcUa's auth structure into parity with ScadaBridge.
+
+**Architecture:** Single Cookie auth scheme. The JWT keeps minting (via `JwtTokenService`) and validating (in `CookieAuthenticationStateProvider`) as the **cookie payload only**; no `AddJwtBearer`, no parallel `Authorization: Bearer` validation. Cookie config (`Name`, `ExpiryMinutes`, `RequireHttpsCookie`) flows through the existing-but-unused `OtOpcUaCookieOptions` via a `Configure<IOptions<OtOpcUaCookieOptions>, ILoggerFactory>` PostConfigure step — same pattern ScadaBridge uses.
+
+**Tech stack:** .NET 10 / ASP.NET Core / `Microsoft.AspNetCore.Authentication.Cookies` only (drop `Microsoft.AspNetCore.Authentication.JwtBearer` from the wiring if its only remaining transitive use disappears with this change).
+
+---
+
+## 1. Architecture
+
+### Schemes
+
+| Before | After |
+|---|---|
+| Cookie (primary) + JwtBearer (parallel) | Cookie only |
+| `FallbackPolicy` lists both schemes | `FallbackPolicy` lists Cookie only |
+| `OnRedirectToLogin` overridden to 401 | default behavior: 302 for browsers, 401 for AJAX |
+| `OnRedirectToAccessDenied` overridden to 403 | default behavior: 302 to `/Account/AccessDenied` (404s today; matches ScadaBridge) |
+
+### Cookie config — externalized via `OtOpcUaCookieOptions`
+
+```csharp
+public sealed class OtOpcUaCookieOptions
+{
+    public const string SectionName = "Security:Cookie";
+
+    public string Name { get; set; } = "ZB.MOM.WW.OtOpcUa.Auth";
+    public int ExpiryMinutes { get; set; } = 30;
+    public bool RequireHttpsCookie { get; set; } = true;
+}
+```
+
+Wired into `CookieAuthenticationOptions` via:
+```csharp
+services.AddOptions<CookieAuthenticationOptions>(CookieAuthenticationDefaults.AuthenticationScheme)
+    .Configure<IOptions<OtOpcUaCookieOptions>, ILoggerFactory>((cookieOpts, ourOpts, lf) =>
+    {
+        cookieOpts.Cookie.Name        = ourOpts.Value.Name;
+        cookieOpts.ExpireTimeSpan     = TimeSpan.FromMinutes(ourOpts.Value.ExpiryMinutes);
+        cookieOpts.SlidingExpiration  = true;
+        cookieOpts.Cookie.SecurePolicy = ourOpts.Value.RequireHttpsCookie
+            ? CookieSecurePolicy.Always
+            : CookieSecurePolicy.SameAsRequest;
+        if (!ourOpts.Value.RequireHttpsCookie)
+        {
+            lf.CreateLogger("ZB.MOM.WW.OtOpcUa.Security").LogWarning(
+                "Security:Cookie:RequireHttpsCookie is DISABLED — auth cookie SecurePolicy is SameAsRequest. " +
+                "Cookie travels in cleartext over plain HTTP. Dev-only.");
+        }
+    });
+```
+
+### Endpoint surface — unchanged
+
+| Path | Auth | Behavior |
+|---|---|---|
+| `POST /auth/login` | AllowAnonymous | LDAP auth → SignInAsync(Cookie); JSON callers get 204 / 401 / 503, form posters get 302 + cookie |
+| `POST /auth/logout` | RequireAuthorization | SignOutAsync(Cookie) |
+| `GET /auth/ping` | AllowAnonymous (handler-returns 200/401) | Polled by Blazor every 60s |
+| `POST /auth/token` | RequireAuthorization | Mints JWT for hypothetical external callers (matches ScadaBridge — they keep this even without JwtBearer wired) |
+
+### Cookie rename
+
+Old: `OtOpcUa.Auth`. New: `ZB.MOM.WW.OtOpcUa.Auth`. Effect: all sessions in flight at deploy time are invisible to the new handler → users re-prompt for login on next protected GET. No security impact (the old cookie expires per its own sliding window; nothing reads it).
+
+---
+
+## 2. Components
+
+### Files modified
+
+| File | Change |
+|---|---|
+| `src/Server/.../Security/CookieOptions.cs` | Add `RequireHttpsCookie`; change `Name` default to `ZB.MOM.WW.OtOpcUa.Auth` |
+| `src/Server/.../Security/ServiceCollectionExtensions.cs` | Drop `using JwtBearer`; delete `ConfigureJwtBearerFromTokenService` class; drop `.AddJwtBearer` + its IPostConfigureOptions registration; drop `OnRedirectToLogin` / `OnRedirectToAccessDenied` overrides; add `LoginPath` + `LogoutPath`; add PostConfigure block consuming `OtOpcUaCookieOptions`; remove `JwtBearerDefaults.AuthenticationScheme` from `FallbackPolicy` builder |
+| `tests/Server/.../Security.Tests/AuthEndpointsIntegrationTests.cs` | Update the `Set-Cookie` assertion on the login-success test from `OtOpcUa.Auth=` → `ZB.MOM.WW.OtOpcUa.Auth=` |
+
+### Files NOT modified
+
+| File | Why |
+|---|---|
+| `Endpoints/AuthEndpoints.cs` | Endpoint contracts unchanged |
+| `Jwt/JwtTokenService.cs` | Still mints JWT into cookie payload |
+| `Blazor/CookieAuthenticationStateProvider.cs` | Still polls `/auth/ping` |
+| `Ldap/*` | Untouched |
+| Razor login page | POST target unchanged |
+| `appsettings*.json` | Defaults are production-safe; no required config edit |
+
+### Tests added
+
+Single new file or appended class in `tests/Server/.../Security.Tests/`:
+
+```csharp
+public class AuthChallengeTests : AuthEndpointsTestBase
+{
+    [Fact]
+    public async Task Root_anonymous_browser_GET_redirects_to_login()
+    {
+        var client = NewClient(allowAutoRedirect: false);
+        client.DefaultRequestHeaders.Accept.ParseAdd("text/html");
+        var resp = await client.GetAsync("/", Ct);
+        resp.StatusCode.ShouldBe(HttpStatusCode.Found);                       // 302
+        resp.Headers.Location!.ToString().ShouldContain("/login");
+        resp.Headers.Location.ToString().ShouldContain("ReturnUrl");
+    }
+
+    [Fact]
+    public async Task Root_anonymous_xhr_GET_returns_401()
+    {
+        var client = NewClient(allowAutoRedirect: false);
+        client.DefaultRequestHeaders.Add("X-Requested-With", "XMLHttpRequest");
+        var resp = await client.GetAsync("/", Ct);
+        resp.StatusCode.ShouldBe(HttpStatusCode.Unauthorized);
+        // Framework still writes a Location header alongside the 401 — AJAX clients ignore it.
+    }
+}
+```
+
+**Framework reality vs. earlier hypothesis:** The ASP.NET Core cookie handler's `IsAjaxRequest` heuristic checks ONLY the `X-Requested-With: XMLHttpRequest` header, NOT the `Accept` content type. A request with `Accept: application/json` but no XHR header is classified as a browser → 302. The third test originally proposed (`Root_anonymous_json_GET_returns_401`) was dropped because it tests behavior the framework doesn't have. ScadaBridge accepts the same framework reality (it doesn't override the heuristic either).
+
+### Package references
+
+`src/Server/ZB.MOM.WW.OtOpcUa.Security/ZB.MOM.WW.OtOpcUa.Security.csproj`: remove `<PackageReference Include="Microsoft.AspNetCore.Authentication.JwtBearer" />` if grep confirms `JwtTokenService` doesn't itself need it (it uses `Microsoft.IdentityModel.Tokens` for validation parameters, separate package).
+

+
+## 3. Data flow
+
+### Anonymous browser hits `/`
+
+```
+Browser → GET /
+          Accept: text/html
+                              ┌──> AuthN: no cookie → unauthenticated
+                              ├──> AuthZ FallbackPolicy fails
+                              └──> Cookie HandleChallengeAsync:
+                                     - Accept: text/html → browser
+                                     - 302 Location: /login?ReturnUrl=%2F
+Browser → GET /login          ← redirect followed; login page renders (AllowAnonymous)
+[user submits form]
+Browser → POST /auth/login    Content-Type: application/x-www-form-urlencoded
+                              ─── LoginAsync:
+                                    - LDAP authenticate
+                                    - SignInAsync(Cookie)
+                                    - Set-Cookie: ZB.MOM.WW.OtOpcUa.Auth=...
+                                    - 302 Location: / (or ReturnUrl)
+Browser → GET /               cookie present → AuthZ passes → 200 + Razor render
+```
+
+### XHR / fetch hits a protected endpoint without cookie
+
+```
+fetch('/api/something')       Accept: application/json
+                              X-Requested-With: XMLHttpRequest
+                              ┌──> AuthN: no cookie → unauthenticated
+                              ├──> AuthZ FallbackPolicy fails
+                              └──> Cookie HandleChallengeAsync:
+                                     - not text/html → API client
+                                     - 401 (no body, no Location)
+```
+
+The cookie handler's built-in `IsAjaxRequest` heuristic is what makes this work — it looks for `X-Requested-With: XMLHttpRequest`. No custom event handler needed. Note: requests with only `Accept: application/json` (no XHR header) are classified as browsers → 302; AJAX callers should set the XHR header to get 401.
+
+### Logout
+
+```
+fetch('/auth/logout', POST)   cookie present
+                              ─── LogoutAsync (RequireAuthorization passes):
+                                    - SignOutAsync(Cookie)
+                                    - Set-Cookie: ZB.MOM.WW.OtOpcUa.Auth=; expires=...
+                                    - 204 (or browser-form: 302 /login)
+```
+
+### Old cookie ignored
+
+Browser holds stale `OtOpcUa.Auth` from a session that predates the deploy. Cookie scheme is now configured for `ZB.MOM.WW.OtOpcUa.Auth` — old cookie is invisible. User treated as anonymous → 302 to `/login`. Old cookie sits in jar until its own sliding window expires (max 30 min); no security risk because nothing reads it.
+
+### Blazor `/auth/ping` polling
+
+```
+CookieAuthenticationStateProvider → GET /auth/ping every 60s
+                              cookie present → 200
+                              cookie expired/missing → 401
+Blazor → invalidates auth state → re-render → root [Authorize] fails
+       → Cookie HandleChallengeAsync → 302 /login
+```
+
+Unchanged.
+
+---
+
+## 4. Error handling
+
+| Surface | Behavior |
+|---|---|
+| Unknown `Accept` (`*/*`, missing, JSON) | Framework default: treated as non-AJAX → 302 to `/login`. The cookie handler's `IsAjaxRequest` only looks at `X-Requested-With`, NOT `Accept`. CLI tools that want a 401 should set `X-Requested-With: XMLHttpRequest`. |
+| `LoginAsync` bad creds | JSON: `401`. Form: `302 /login?error=…&returnUrl=…`. Handler-returned, unaffected by middleware changes. |
+| `LoginAsync` LDAP throws | `503 ServiceUnavailable`. Handler-returned. |
+| `LoginAsync` success | JSON: `204`. Form: `302 /` (or `ReturnUrl`). |
+| Cookie expires mid-request | Treated as anonymous → 302 to `/login` (browser) or 401 (AJAX). Active users kept alive by `SlidingExpiration = true`. |
+| `RequireHttpsCookie = false` over HTTPS | Cookie marked `SecurePolicy = SameAsRequest`. Misconfiguration risk; startup logs Warning every boot so it's audible. No validator-refused boot — default is `true`; dev compose explicitly opts out. |
+| Missing `Security:Cookie` section in config | `.Bind()` no-ops; defaults take over (`Name = ZB.MOM.WW.OtOpcUa.Auth`, `ExpiryMinutes = 30`, `RequireHttpsCookie = true`). Production-safe. |
+| `[Authorize(Policy="DriverOperator")]` denied for authenticated non-operator | Cookie handler redirects to default `AccessDeniedPath = "/Account/AccessDenied"` which 404s in OtOpcUa. Matches ScadaBridge; rare enough not to be a P0. Follow-up: add a minimal `/access-denied` Razor page. |
+
+---
+
+## 5. Testing
+
+### Existing tests pass unchanged
+
+- `Login_with_invalid_credentials_returns_401` — handler-returned, unaffected
+- `Login_when_ldap_throws_returns_503` — handler-returned, unaffected
+- `Ping_anonymous_returns_401` — handler-returned, unaffected
+- `Ping_after_cookie_login_returns_200` — uses HttpClient cookie container, picks up renamed cookie automatically
+- `Login_with_cookie_credentials_returns_204_and_sets_cookie` — needs one assertion update (cookie name)
+
+### Tests added (3 new)
+
+- `Root_anonymous_browser_GET_redirects_to_login` — asserts 302 + `Location` contains `/login` + `ReturnUrl`
+- `Root_anonymous_ajax_GET_returns_401` — `X-Requested-With: XMLHttpRequest` → 401, no `Location`
+  (the originally planned `Root_anonymous_json_GET_returns_401` was dropped — see Section 3 framework-reality note above)
+
+### Removed/orphaned tests
+
+None expected. The explore phase found no test depending on `ConfigureJwtBearerFromTokenService` or the `WWW-Authenticate: Bearer` response. Grep at plan-write time to confirm.
+
+### Manual smoke (docker-dev stack)
+
+1. `http://localhost:9200/` anonymously → expect 302 to `/login?ReturnUrl=%2F` (was: Chrome error page)
+2. Sign in via the form
+3. `http://localhost:9200/` authenticated → expect Razor dashboard
+4. DevTools → Application → Cookies → confirm `ZB.MOM.WW.OtOpcUa.Auth`
+5. `curl -i http://localhost:9200/` → `302 Found`, Location: `/login?ReturnUrl=%2F`
+6. `curl -i -H "Accept: application/json" http://localhost:9200/` → `401 Unauthorized`
+
+### Verification gates at PR time
+
+- `dotnet build ZB.MOM.WW.OtOpcUa.slnx` — zero new errors (pre-existing 12 unchanged)
+- `dotnet test tests/Server/ZB.MOM.WW.OtOpcUa.Security.Tests/` — all green
+- `dotnet test tests/Server/ZB.MOM.WW.OtOpcUa.AdminUI.Tests/` — all green
+- Manual Chrome smoke above passes
+
+---
+
+## 6. Sequencing (for plan-writing)
+
+Single-PR feature, but split into reviewable phases:
+
+1. **Phase 1 — Options class.** Extend `OtOpcUaCookieOptions` with `RequireHttpsCookie` and new `Name` default. Tests unaffected.
+2. **Phase 2 — Wiring rewrite.** Edit `ServiceCollectionExtensions.cs`: drop JwtBearer, drop event overrides, add `LoginPath`/`LogoutPath`, add PostConfigure consumption of `OtOpcUaCookieOptions`. Update the one existing test assertion. Build + existing Security.Tests green.
+3. **Phase 3 — New challenge tests.** Add the 3 new redirect/401 tests.
+4. **Phase 4 — Package cleanup.** Remove `Microsoft.AspNetCore.Authentication.JwtBearer` from csproj if grep confirms no remaining consumer.
+5. **Phase 5 — Manual smoke + commit.** Restart admin-a/admin-b in docker-dev; verify in Chrome.
+
+---
+
+## Decisions table
+
+| # | Decision | Rationale |
+|---|---|---|
+| 1 | Drop JwtBearer server-side scheme | No in-repo consumer; brought non-redirect 401 + `WWW-Authenticate: Bearer` to browser GETs |
+| 2 | Keep `JwtTokenService` + `/auth/token` | Token-as-cookie-payload is load-bearing for Blazor; `/auth/token` matches ScadaBridge surface |
+| 3 | Rename cookie `OtOpcUa.Auth` → `ZB.MOM.WW.OtOpcUa.Auth` | Naming parity with ScadaBridge; one-time forced sign-out acceptable |
+| 4 | Externalize via existing `OtOpcUaCookieOptions` + PostConfigure | Mirrors ScadaBridge pattern; fixes pre-existing bug where options class was bound but ignored |
+| 5 | Drop both `OnRedirectToLogin` and `OnRedirectToAccessDenied` overrides | Restores framework's browser-vs-AJAX heuristic; ScadaBridge does the same |
+| 6 | Set `LoginPath = "/login"`, `LogoutPath = "/auth/logout"` | Required for the framework's default redirect to work |
+| 7 | Accept 404 on `/Account/AccessDenied` for v1 | Matches ScadaBridge; rare path; follow-up to add minimal page |
+| 8 | Warning-log when `RequireHttpsCookie = false` | Audible misconfig signal; same as ScadaBridge |

+# Auth/login alignment with ScadaBridge — implementation plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use `superpowers-extended-cc:executing-plans` or `superpowers-extended-cc:subagent-driven-development` to implement this plan task-by-task.
+
+**Goal:** Match ScadaBridge's single-Cookie auth pattern: drop the unused JwtBearer parallel scheme, restore the framework's default browser-vs-AJAX challenge heuristic, and externalize cookie config through the existing-but-unused `OtOpcUaCookieOptions`.
+
+**Architecture:** Cookie-only auth. `JwtTokenService` keeps minting JWTs as the cookie payload (Blazor circuit hydration depends on it). Cookie name + idle timeout + HTTPS policy flow through `OtOpcUaCookieOptions` via a `Configure<IOptions<OtOpcUaCookieOptions>, ILoggerFactory>` PostConfigure step. Endpoint surface (`/auth/login`, `/auth/logout`, `/auth/ping`, `/auth/token`) unchanged.
+
+**Tech stack:** .NET 10 / ASP.NET Core / `Microsoft.AspNetCore.Authentication.Cookies` / xUnit v3 + Shouldly / `Microsoft.AspNetCore.TestHost.TestServer`.
+
+**Design doc:** `docs/plans/2026-05-29-auth-alignment-design.md` (commit `bc4fce5`). Each task below cites the design section it implements.

+
+## Task 3 — Add browser-vs-AJAX challenge tests
+
+**Classification:** small
+**Estimated implement time:** ~4 min
+**Parallelizable with:** Task 4
+
+**Files:**
+- Modify: `tests/Server/ZB.MOM.WW.OtOpcUa.Security.Tests/AuthEndpointsIntegrationTests.cs` (append 3 new test methods + 1 helper)
+
+**Implements design:** Section 5 "Tests added" + Section 4 "Auth challenge for unknown content type".
+
+### Context for the implementer
+
+`AuthEndpointsIntegrationTests` is `IAsyncLifetime`-backed and stands up a `TestServer` with `MapOtOpcUaAuth()` mounted (line 66). The `web.UseEndpoints(e => e.MapOtOpcUaAuth())` wires ONLY the four `/auth/*` endpoints — there is NO root `MapGet("/", ...)` registered. So an anonymous GET to `/` hits the routing pipeline, falls through to a 404 BEFORE auth middleware even challenges.
+
+**The test harness needs a protected root endpoint.** Add one in `InitializeAsync` inside the `web.UseEndpoints(...)` callback. Then the 3 new tests will exercise the cookie scheme's challenge for that protected route.
+
+### Step 1: Modify the test host setup
+
+In `AuthEndpointsIntegrationTests.cs`, change `web.UseEndpoints(...)` (around line 66) from:
+```csharp
+app.UseEndpoints(e => e.MapOtOpcUaAuth());
+```
+to:
+```csharp
+app.UseEndpoints(e =>
+{
+    e.MapOtOpcUaAuth();
+    // Protected root used by AuthChallengeTests below — exercises the cookie
+    // scheme's challenge heuristic without depending on the full Razor host.
+    e.MapGet("/", () => Results.Ok("authenticated")).RequireAuthorization();
+});
+```
+
+### Step 2: Add the three new test methods
+
+Append at the bottom of the class (before the closing brace), keeping the file's existing summary style and using `TestContext.Current.CancellationToken` via the existing `Ct` property:
+
+```csharp
+/// <summary>Anonymous browser GET of a protected route redirects to /login with a ReturnUrl.</summary>
+[Fact]
+public async Task Root_anonymous_browser_GET_redirects_to_login()
+{
+    var client = NewClientNoRedirect();
+    var req = new HttpRequestMessage(HttpMethod.Get, "/");
+    req.Headers.Accept.ParseAdd("text/html");
+    var resp = await client.SendAsync(req, Ct);
+
+    resp.StatusCode.ShouldBe(HttpStatusCode.Found);
+    resp.Headers.Location.ShouldNotBeNull();
+    resp.Headers.Location!.OriginalString.ShouldContain("/login");
+    resp.Headers.Location.OriginalString.ShouldContain("ReturnUrl");
+}
+
+/// <summary>Anonymous AJAX GET of a protected route returns 401 with no Location.</summary>
+[Fact]
+public async Task Root_anonymous_ajax_GET_returns_401()
+{
+    var client = NewClientNoRedirect();
+    var req = new HttpRequestMessage(HttpMethod.Get, "/");
+    req.Headers.Add("X-Requested-With", "XMLHttpRequest");
+    var resp = await client.SendAsync(req, Ct);
+
+    resp.StatusCode.ShouldBe(HttpStatusCode.Unauthorized);
+    resp.Headers.Location.ShouldBeNull();
+}
+
+/// <summary>Anonymous JSON GET of a protected route returns 401.</summary>
+[Fact]
+public async Task Root_anonymous_json_GET_returns_401()
+{
+    var client = NewClientNoRedirect();
+    var req = new HttpRequestMessage(HttpMethod.Get, "/");
+    req.Headers.Accept.ParseAdd("application/json");
+    var resp = await client.SendAsync(req, Ct);
+
+    resp.StatusCode.ShouldBe(HttpStatusCode.Unauthorized);
+}
+```
+
+### Step 3: Add the no-redirect client helper
+
+Right next to the existing `NewClient()` method (line 82):
+
+```csharp
+/// <summary>Creates a TestServer-backed HttpClient that does NOT auto-follow redirects.
+/// Used by challenge tests so we can assert on the 302 / Location directly.</summary>
+private HttpClient NewClientNoRedirect() => new(_server.CreateHandler())
+{
+    BaseAddress = _server.BaseAddress,
+};
+```
+
+### Step 4: Run the tests
+
+```bash
+cd /Users/dohertj2/Desktop/OtOpcUa
+dotnet test tests/Server/ZB.MOM.WW.OtOpcUa.Security.Tests/
+```
+
+Expected: existing 5 tests still pass + 3 new tests pass = 8+ total green.
+
+**If `Root_anonymous_browser_GET_redirects_to_login` returns 200 instead of 302**: HttpClient is still auto-following redirects. Two fixes to try in order:
+1. Confirm `NewClientNoRedirect` uses `_server.CreateHandler()` (not `CreateClient()`).
+2. If still wrong, swap to: `var handler = new HttpClientHandler { AllowAutoRedirect = false };` — but TestServer doesn't expose HttpClientHandler directly. The `CreateHandler()` path SHOULD return a non-redirecting handler; if it doesn't, the implementation may need a `DelegatingHandler` wrapper.
+
+**If `Root_anonymous_browser_GET_redirects_to_login` returns 401 instead of 302**: the cookie scheme isn't classifying `Accept: text/html` as a browser. Inspect Task 2's changes — `OnRedirectToLogin` may not have been fully removed, OR `LoginPath` was not set, OR an `Accept` parsing issue. Look at the response body — if it's empty + 401, the JwtBearer scheme or the override is still in play.
+
+### Step 5: Commit
+
+```bash
+git -C /Users/dohertj2/Desktop/OtOpcUa add tests/Server/ZB.MOM.WW.OtOpcUa.Security.Tests/AuthEndpointsIntegrationTests.cs
+git -C /Users/dohertj2/Desktop/OtOpcUa commit -m "test(security): add browser-vs-AJAX challenge tests for root path"
+```
+
+### Output report
+
+- 3 new tests + 1 helper + modified InitializeAsync
+- Build clean
+- Test count: existing N + 3 new = N+3 green
+- Commit SHA
+- Anything unexpected (e.g. redirect-following behavior of `_server.CreateHandler()`)
+
+### Self-review checklist
+
+- [ ] `MapGet("/", ...).RequireAuthorization()` added inside `web.UseEndpoints(...)`
+- [ ] `NewClientNoRedirect()` helper added
+- [ ] 3 new `[Fact]` methods added with `TestContext.Current.CancellationToken` via the `Ct` property

+
+## Task 4 — Remove `Microsoft.AspNetCore.Authentication.JwtBearer` package reference
+
+**Classification:** trivial
+**Estimated implement time:** ~2 min
+**Parallelizable with:** Task 3
+
+**Files:**
+- Modify: `src/Server/ZB.MOM.WW.OtOpcUa.Security/ZB.MOM.WW.OtOpcUa.Security.csproj` (delete one line)
+- Verify: `Directory.Packages.props` — leave the `<PackageVersion Include="Microsoft.AspNetCore.Authentication.JwtBearer" ... />` entry in place (other projects may consume it).
+
+**Implements design:** Section 2 "Package references" + Section 6 phase 4.
+
+### Step 1: Confirm no remaining consumer in the Security project
+
+```bash
+grep -rn "Microsoft\.AspNetCore\.Authentication\.JwtBearer\|JwtBearer" \
+  /Users/dohertj2/Desktop/OtOpcUa/src/Server/ZB.MOM.WW.OtOpcUa.Security/ \
+  --include="*.cs"
+```
+
+Expected: zero matches. (Task 2 removed all uses.) If there are matches, STOP and report — Task 2 was incomplete.
+
+### Step 2: Remove the PackageReference
+
+In `src/Server/ZB.MOM.WW.OtOpcUa.Security/ZB.MOM.WW.OtOpcUa.Security.csproj`, find this line (currently around line 13):
+```xml
+<PackageReference Include="Microsoft.AspNetCore.Authentication.JwtBearer"/>
+```
+Delete it. **Keep** these:
+```xml
+<PackageReference Include="Microsoft.IdentityModel.Tokens"/>
+<PackageReference Include="System.IdentityModel.Tokens.Jwt"/>
+```
+(`JwtTokenService` consumes those for `TokenValidationParameters` + JWT creation respectively — they're not from the JwtBearer authentication package.)
+
+### Step 3: Check whether ANY other project still references the package
+
+```bash
+grep -rn "Microsoft\.AspNetCore\.Authentication\.JwtBearer" \
+  /Users/dohertj2/Desktop/OtOpcUa/src/ /Users/dohertj2/Desktop/OtOpcUa/tests/ \
+  --include="*.csproj"
+```
+
+If zero results: also remove the `<PackageVersion Include="Microsoft.AspNetCore.Authentication.JwtBearer" ...>` line from `Directory.Packages.props` (search for it). If one or more other projects still reference it, leave `Directory.Packages.props` alone.
+
+### Step 4: Restore + build
+
+```bash
+cd /Users/dohertj2/Desktop/OtOpcUa
+dotnet restore src/Server/ZB.MOM.WW.OtOpcUa.Security/
+dotnet build src/Server/ZB.MOM.WW.OtOpcUa.Security/
+dotnet build ZB.MOM.WW.OtOpcUa.slnx
+```
+
+Expected: 0 NEW errors. The known pre-existing 12 errors (OpcUaServer.Tests + Runtime.Tests + AbLegacy.Cli + S7.Cli) remain unchanged.
+
+### Step 5: Commit
+
+```bash
+git -C /Users/dohertj2/Desktop/OtOpcUa add \
+  src/Server/ZB.MOM.WW.OtOpcUa.Security/ZB.MOM.WW.OtOpcUa.Security.csproj \
+  Directory.Packages.props  # only if you also removed it from Directory.Packages.props
+git -C /Users/dohertj2/Desktop/OtOpcUa commit -m "chore(security): drop Microsoft.AspNetCore.Authentication.JwtBearer (unused)"
+```
+
+If only the csproj changed: omit `Directory.Packages.props` from the add.
+
+### Output report
+
+- Was Directory.Packages.props also touched? Justify based on whether other projects still reference the package.
+- Build clean (0 new errors)
+- Commit SHA
+
+### Self-review checklist
+
+- [ ] Confirmed zero `Microsoft.AspNetCore.Authentication.JwtBearer` or `JwtBearer` matches in `src/Server/ZB.MOM.WW.OtOpcUa.Security/**/*.cs` before deletion
+- [ ] PackageReference removed from Security.csproj
+- [ ] `Microsoft.IdentityModel.Tokens` and `System.IdentityModel.Tokens.Jwt` kept
+- [ ] Directory.Packages.props touched ONLY if no other project consumes the package
+- [ ] Full solution build adds zero new errors

+
+## Task 5 — Manual smoke + final commit
+
+**Classification:** trivial
+**Estimated implement time:** ~3 min
+**Parallelizable with:** none
+
+**Files:** none (verification + optional cleanup commit)
+
+**Implements design:** Section 5 "Manual smoke" + Section 6 phase 5.
+
+### Step 1: Restart the docker-dev cluster
+
+The admin nodes need to pick up the new `Microsoft.AspNetCore.TestHost`-side code path AND the new cookie name. Since the in-cluster admin processes run a prior build, force a rebuild + recreate:
+
+```bash
+cd /Users/dohertj2/Desktop/OtOpcUa
+docker compose -f docker-dev/docker-compose.yml up -d --build admin-a admin-b
+```
+
+Wait ~15 s for warm-up. Then:
+
+```bash
+docker compose -f docker-dev/docker-compose.yml ps admin-a admin-b
+```
+
+Both should show `Up` and `(healthy)` (or `Up` if no healthcheck).
+
+### Step 2: curl smoke
+
+```bash
+# Anonymous browser-shaped GET → 302 to /login with ReturnUrl
+curl -i -H "Accept: text/html" http://localhost:9200/ 2>&1 | head -12
+# Expected: HTTP/1.1 302 Found, Location: /login?ReturnUrl=%2F
+
+# Anonymous AJAX GET → 401
+curl -i -H "X-Requested-With: XMLHttpRequest" http://localhost:9200/ 2>&1 | head -8
+# Expected: HTTP/1.1 401 Unauthorized
+
+# Anonymous JSON GET → 401
+curl -i -H "Accept: application/json" http://localhost:9200/ 2>&1 | head -8
+# Expected: HTTP/1.1 401 Unauthorized
+
+# Login form → 302 with Set-Cookie ZB.MOM.WW.OtOpcUa.Auth
+curl -i -X POST -d "username=alice&password=alice" \
+  -H "Content-Type: application/x-www-form-urlencoded" \
+  http://localhost:9200/auth/login 2>&1 | head -15
+# Expected: HTTP/1.1 302 Found, Set-Cookie: ZB.MOM.WW.OtOpcUa.Auth=... (the test stub user may differ — check docker-compose's GLAuth seed for a valid LDAP creds pair)
+```
+
+### Step 3: Chrome smoke (via the macbook browser instance from earlier in the session)
+
+1. Open `http://localhost:9200/` — should redirect to `/login?ReturnUrl=%2F` (not Chrome's error page)
+2. Sign in via the form
+3. DevTools → Application → Cookies → confirm cookie name is `ZB.MOM.WW.OtOpcUa.Auth`
+4. Navigate to `http://localhost:9200/` again — should render the AdminUI dashboard
+5. Click logout → confirm redirect back to `/login`
+
+### Step 4: Optional CLAUDE.md update
+
+If `CLAUDE.md` mentions the old `OtOpcUa.Auth` cookie name anywhere, update to the new `ZB.MOM.WW.OtOpcUa.Auth`. Run:
+
+```bash
+grep -n "OtOpcUa\.Auth" /Users/dohertj2/Desktop/OtOpcUa/CLAUDE.md
+```
+
+If matches: update them, otherwise skip.
+
+### Step 5: Final commit (only if Step 4 changed CLAUDE.md)
+
+```bash
+git -C /Users/dohertj2/Desktop/OtOpcUa add CLAUDE.md
+git -C /Users/dohertj2/Desktop/OtOpcUa commit -m "docs: update cookie name reference in CLAUDE.md"
+```
+
+### Output report
+
+- All 4 curl smoke checks passed?
+- Chrome smoke passed?
+- CLAUDE.md changed?
+- Final SHA on master (if any docs commit)
+- Commit count since this plan started (vs `bc4fce5`)
+
+### Self-review checklist
+
+- [ ] `docker compose up -d --build admin-a admin-b` succeeded
+- [ ] All 4 curl smoke checks return expected status codes
+- [ ] Chrome smoke shows redirect to `/login`, then dashboard after auth
+- [ ] Cookie name in DevTools matches `ZB.MOM.WW.OtOpcUa.Auth`
+- [ ] No new commits left uncommitted in the working tree
+
+---
+
+## Verification gates (apply at end of every task)
+
+- `dotnet build src/Server/ZB.MOM.WW.OtOpcUa.Security/` — 0 errors
+- `dotnet test tests/Server/ZB.MOM.WW.OtOpcUa.Security.Tests/` — all green (existing + new)
+- `dotnet build ZB.MOM.WW.OtOpcUa.slnx` — no NEW errors beyond the 12 pre-existing
+- No untracked files staged accidentally (especially `sql_login.txt`, `pki/`, doc-fix artifacts)
+
+---
+
+## Risk hot-spots for reviewers
+
+1. **TestServer's no-redirect HttpClient.** The plan assumes `new HttpClient(_server.CreateHandler()) { BaseAddress = _server.BaseAddress }` does NOT auto-follow redirects. If it does, the `Root_anonymous_browser_GET_redirects_to_login` test fails with 200 instead of 302. Fix path documented in Task 3 Step 4.
+2. **Framework default of `Accept: */*` → 302.** Curl's default Accept header is `*/*`, which the framework classifies as browser → 302. Documented behavior, mirrors ScadaBridge; reviewers should not flag the smoke step that uses `Accept: text/html` as redundant — it's the explicit "browser" assertion.
+3. **Cookie rename invalidates sessions.** The deploy effectively logs every currently-signed-in user out. Document in commit body; the cluster was just restarted on the new API key anyway, so the timing is opportune.
+4. **`Directory.Packages.props` change is conditional.** Don't touch it if other projects still consume the JwtBearer package. Task 4 has explicit grep guard.
+5. **`/Account/AccessDenied` 404.** Authenticated users hitting a `DriverOperator`-only route now get a generic 404 page instead of a clean access-denied message. Documented design choice; follow-up to add a Razor page if UX feedback demands it.

Extract AddOtOpcUaDriverProbes() (idempotent via TryAddEnumerable) and call it in the hasAdmin path too. - Live driver-status/alerts/script-log panels showed "SignalR error: Connection refused": these Blazor Server components opened a HubConnection to their own hub via the browser's public URL, which server-side code can't reach behind Traefik (host :9200 -> container :9000).

So all four nested option records read as null -> FromRecord NRE (HTTP 500) on edit, and the form would have shown defaults instead of the real config (risking a clobber on save). Fix: add PropertyNameCaseInsensitive=true (matches the runtime) so real values load, plus null-coalesce the nested records in FromRecord as defense-in-depth. Regression test asserts the seeded PascalCase config loads its real values.	2026-05-29 12:45:44 -04:00
