Behaviour-neutral hop: pin the SDK AggregateManager default to our
TreatUncertainAsBad=false (SDK .182 flipped it to true), parity guard now an
explicit deliberate-divergence assertion plus a booted-server check; adapt to
obsolete FindPredefinedNode(Type)/TraceConfiguration; Microsoft.Extensions.
Logging.Abstractions 10.0.7 -> 10.0.8 (SDK floor); stall wire test's late-flush
positive control is best-effort (.176 preserves publish queue ordering).

AbLegacyDriver stamped LastSuccessfulRead (init, read, write), the read's sample
timestamps and host-state change times from raw DateTime.UtcNow; only the backoff
path read the injectable Clock. All of them now read Clock(), so
NativePcccBridgeStatusHealthTests drives a manual clock (init at T0, read at T1)
and asserts LastSuccessfulRead == T1 exactly instead of spin-waiting for the wall
clock to pass the init stamp (#767). Without the driver change the 6 tests fail
(init stamp is wall-clock, not T0).
Directory.Build.props sets TreatWarningsAsErrors for every project since #766, so
the 75 per-csproj copies (64 src + 11 tests) are removed and the props comment
says it is now the only place. tools/mem-probe keeps its explicit opt-out.
Release build: 0 warnings, 0 errors; a planted CS0168 still fails the build in a
src project and in a test project that used to carry its own copy.

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.
