G-7 wired OpcUaClientTagDefinitionFactory.Inspect into the deploy-time TagConfig
gate, which gave ControlPlane a ProjectReference to
Driver.OpcUaClient.Contracts — and with it, transitively, the whole OPC UA client
stack (5 OPCFoundation packages) into every host that loads the control plane.
NamespaceMap was the only reason Contracts carried
OPCFoundation.NetStandard.Opc.Ua.Client: its entire public surface is
ISession/NamespaceTable/NodeId-typed. It moves to a new leaf project,
ZB.MOM.WW.OtOpcUa.Driver.OpcUaClient.Session, referenced by the runtime .Driver
and by .Browser. Contracts is left with Core.Abstractions and NOTHING else —
the same shape as Calculation.Contracts.
The namespace stays ZB.MOM.WW.OtOpcUa.Driver.OpcUaClient, so no consumer's
`using` changed. The .Session -> .Contracts direction is deliberate: the blob
read NamespaceMap needs is OpcUaClientTagDefinitionFactory.TryReadNodeId, the
one authority it shares with the deploy gate, and that must stay in the
dependency-light half.
Why a new project rather than folding NamespaceMap into the runtime .Driver and
having .Browser reference it (the Driver.Mqtt.Browser #512-style deliberate
exception): the AdminUI project-references .Browser and NOT .Driver, so that
shape would pull the OpcUaClient driver runtime — plus Core,
Opc.Ua.Configuration and Secrets.Abstractions — into the AdminUI's build/deploy
graph. That is exactly the violation #512 spent two extractions removing from
Mqtt.Browser; re-introducing it to save one csproj is a bad trade.
Guard: ContractsIsDependencyLightTests (Driver.OpcUaClient.Tests) asserts the
Contracts manifest names no Opc.Ua* assembly, plus a counterpart asserting
.Session does. An ABSENCE assertion is sound on the manifest where a presence
one is not — the compiler elides an unused reference, but it MUST emit one the
moment Opc.Ua-typed code is added. Falsified by temporarily re-adding the
package plus an Opc.Ua.NodeId-typed member: red on Opc.Ua.Types, green again on
removal.
Evidence — `dotnet list ControlPlane package --include-transitive | grep -i opc`:
before: OPCFoundation.NetStandard.Opc.Ua.{Client,Configuration,Core,
Security.Certificates,Types} 1.5.378.106
after: none (and 0 Opc.Ua*.dll in ControlPlane's output directory)
Cross-module fix from the review sweep. -003 (Medium): the browser's JsonOpts lacked
JsonStringEnumConverter (the factory+probe both carry it), so AdminUI string-enum configs
(AuthType/SecurityPolicy/SecurityMode/TargetNamespaceKind) threw on deserialize. Added the
converter (accepts string AND numeric) + TDD.
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.
