The tests probe a free port (bind 0, release) and start the SDK server later; under a
highly parallel run another test can take the port in between and the SDK fails with
'Failed to establish tcp listener sockets for Ipv4 and IPv6.'. OpcUaHostStart.StartAsync
builds a fresh host + server on a fresh port per attempt (up to 5) when the failure is a
bind failure; all 45 start sites in OpcUaServer.Tests, OpcUaServer.IntegrationTests and
Runtime.Tests use it. Per-attempt GUID ApplicationUris are hoisted out of the host factory
because a changed URI against a reused PKI store fails with 'Cannot access private key'.

All five suppressed advisories are now resolved at baseline/resolved versions,
so every NuGetAuditSuppress is removed repo-wide:
- System.Security.Cryptography.Xml (GHSA-37gx-xxp4-5rgx / GHSA-w3x6-4m5h-cxqf)
-> fixed by the .NET 10 baseline (10.0.6)
- OPCFoundation Opc.Ua.Core (GHSA-h958-fxgg-g7w3) -> fixed at resolved 1.5.378.106
Two were still live and are now patched via direct security pins:
- OpenTelemetry.Api 1.9.0 -> 1.15.3 (GHSA-g94r-2vxg-569j) pinned in Cluster;
Runtime/ControlPlane/AdminUI + tests inherit via project reference
- Tmds.DBus.Protocol 0.20.0 -> 0.21.3 (GHSA-xrw6-gwf8-vvr9) pinned in Client.UI
Also correct the Historian sidecar runtime comments (x86 -> x64, matching the
csproj PlatformTarget). Solution audit: 0 vulnerable packages; full build clean.
Opc.Ua.Server was pinned 1.5.374.126 while Client/Configuration were 1.5.378.106, so the
published Host unified Opc.Ua.Core to 1.5.378 (which dropped Opc.Ua.INodeIdFactory that Server
1.5.374 referenced). Every driver-role node (and the fused site nodes) failed to start the OPC
UA server with TypeLoadException, leaving the OPC data plane dead and the site UIs at 503.
Align all OPC UA packages to 1.5.378.106 (bump Server; drop the Opc.Ua.Configuration/Client
VersionOverrides in OpcUaServer + its integration tests) and port the server host to the
1.5.378 async API:
- ApplicationInstance requires an ITelemetryContext ctor (DefaultTelemetry.Create)
- Start/Stop/LoadApplicationConfiguration/Validate -> async; CheckApplicationInstanceCertificate
-> CheckApplicationInstanceCertificatesAsync
- ImpersonateEventHandler is now (ISession, ImpersonateEventArgs)
- UserNameIdentityToken.DecryptedPassword is now byte[] (UTF-8 decode)
- tests ported (byte[] passwords; async discovery/session/read client API)
Verified: full solution builds, OpcUaServer unit tests 52/52, and in docker-dev all six OPC
endpoints (4840-4845) listen and the site UIs return 302 (were 503). End-to-end OPC behaviour
(read/write/subscribe/security under 1.5.378) still needs a functional client test.
