Builds TwoNodeClusterHarness: two in-process Host-equivalent nodes sharing
an in-memory ConfigDb. Forms a 2-member Akka cluster. ClusterFormationTests
proves both nodes see each other as admin+driver role members.
Fixes a real production bug uncovered while wiring the harness — Program.cs
ran two separate ActorSystems (one from AddOtOpcUaCluster.AkkaHostedService
with cluster HOCON, one from Akka.Hosting.AddAkka with bare HOCON). Cluster
singletons landed on the bare ActorSystem and could not actually form a
cluster ("Configuration does not contain `akka.cluster` node").
Consolidation:
- AddOtOpcUaCluster now only binds AkkaClusterOptions + registers IClusterRoleInfo
- New WithOtOpcUaClusterBootstrap pushes embedded HOCON + Remote/Cluster options
into Akka.Hosting's AkkaConfigurationBuilder
- AkkaHostedService.cs deleted — Akka.Hosting now owns the lifecycle
- Program.cs + harness call WithOtOpcUaClusterBootstrap inside AddAkka
Why not WebApplicationFactory<Program>? Program.cs reads OTOPCUA_ROLES from
process env (shared across in-process WAFs); the harness replays Program.cs's
DI graph from a clean WebApplicationBuilder per node with per-node config
overrides. Same production extensions, isolated config + Kestrel + Akka ports.
Tests: 93 v2 tests pass (was 91 + 2 new cluster formation), 0 skipped.
Eliminates the services.BuildServiceProvider() captive-provider antipattern
(ASP0000) inside AddJwtBearer. The new ConfigureJwtBearerFromTokenService
resolves JwtTokenService from the real DI container at runtime and stays
in lock-step with JwtTokenService.BuildValidationParameters.
All 27 Security.Tests stay green, including the F1 integration tests that
exercise /auth/token through the real bearer pipeline.
Injects AuthenticationStateProvider and reads the current user's identity
name on Deploy click, replacing the "(current user)" placeholder.
Anonymous case falls back to "(anonymous)" — should never hit in practice
since the page requires FleetAdmin/ConfigEditor.
Mirrors the publisher-injection pattern from FleetStatusBroadcaster and
PeerOpcUaProbeActor: Props accepts an optional Action<object> override so
tests can use a TestProbe sink instead of bootstrapping DistributedPubSub
(unreliable single-node in TestKit).
Un-skips the two RedundancyStateActor tests deferred under F6.
7 tests exercise AddOtOpcUaAuth + MapOtOpcUaAuth end-to-end against an
in-memory ConfigDb + stub ILdapAuthService. Covers /auth/login (204/401/503),
/auth/ping (401/200), /auth/token (200+JWT shape), /auth/logout (204+clear-cookie).
Scope is the auth contract — not the fused Host bootstrap (cluster + role
gating belongs in the Task 58 multi-node harness). HostBuilder + TestServer
is used directly instead of WebApplicationFactory<Program> because the
test project has no Program entry point and Host needs Akka cluster up.
Mirrors WithOtOpcUaControlPlaneSingletons for the driver role. Spawns
DriverHostActor + DbHealthProbeActor on the host's ActorSystem and
registers both under marker keys. Host's Program.cs now calls it when
the node carries the driver role, so driver-only and admin+driver
deployments both auto-bootstrap the per-node actors.
Integration test covers the registration round-trip via Microsoft.Extensions.Hosting
+ Akka.Hosting AddAkka.
Task 56: removes the legacy in-process Server + Admin Web project + their test
projects (Server.Tests, Admin.Tests, Admin.E2ETests). The fused OtOpcUa.Host
binary built across Phases 1-9 is now the sole production entry point.
What happened to the 47 legacy Admin Blazor pages: per follow-up F15, the
v1 architecture's draft/publish UX is replaced by v2's live-edit + snapshot-
deploy model, so a 1:1 migration is not meaningful. The mechanical move via
git mv preserves the history; service classes + page bodies that referenced
removed v1 types (ConfigGeneration, RedundancyRole, GenerationId) were
deleted. AdminUI now ships a minimal Home page + the v2 Deployments page.
Per-page rebuild against the v2 surface is tracked as F15. The v2 Deployments
page (Task 52) is the only first-party UI shipping in this PR.
Task 57: solution build green; 84+ tests green across active v2 + legacy
driver test projects.
