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.
