Marc Schier 9bfc780e14 Update NuGet dependencies and migrate tests to NUnit 5 (#4840)
# Description

Update 55 NuGet dependencies to the latest stable releases available on
2026-10-19, preserving documented compatibility pins and
framework-specific version bands. Existing OpenUSD prereleases remain
unchanged because no newer releases are available.

Migrate existing tests to NUnit 5: await asynchronous assertions,
propagate async through helpers, handle nullable predicates, and replace
obsolete `Order` attributes with sequencing dependencies. Sequencing
dependencies use `AllowFailure = true`; filtering a dependent test also
runs prerequisites. Adjust fixture-level parallelism where NUnit
dependency scheduling requires it.

Keep Roslyn API/runtime pins intact; select newer Immutable/Metadata
runtime packages only for test and profiling hosts requiring them.
Update the approved SDK pin to 10.0.402 across local, CI, and container
builds. Document NUnit 5 conventions.

fc0687a2dc Source generator: a NodeSet2 Variable without a Value has a null Value (#4798)
# Description

A Variable or VariableType in a NodeSet2 that has no Value element has a
null Value (OPC 10000-6 F.5); the runtime NodeSet2 importer loads it
that
way. The source generator initialized such a node with the default value
of its DataType instead ((int)0, (double)0, ...), so a server built from
the generated code reported values the model never declared.

The NodeSet2 importer now records that the node declares no Value
(NodeSetValueIsNull), the flag follows the node into the merged instance
hierarchy, and the node state generator emits Variant.Null for it when
no
value was merged in from elsewhere. ModelDesign inputs, where a missing
DefaultValue implies the DataType default, are unchanged.

The tests generate a DI-style NodeSet2 together with the DI NodeSet2 and
check the generated values of a type's InstanceDeclaration, of an
instance's children with and without a Value, and of a VariableType.

Marc Schier 0374e19121 Add MachineTool, WMTP, GMS and CranesHoists companions (#4765)
# Description

_Describe the changes here to communicate to the maintainers why they
should accept this pull request. By default - this will become the
Commit message after merging and thus define history._

Add provider-backed MachineTool, bundled WMTP, GMS and CranesHoists
companions using the existing Machinery/MachineVision fluent, DI and
typed-client approach. **The PR is open/non-draft by user choice.
Current head `ecc4a7d6ca3e8004cf28ab54da605da302d026bf` is mergeable and
has 108 successful checks, six intentionally skipped checks, zero
failures and zero pending checks. All five primary workflows completed
successfully at that exact head.**

| Family | Released specification/model | Packaging |
| --- | --- | --- |
| MachineTool | OPC 40501-1, 1.02.0 | Model, Server, Client and MCP;
normal root versions |
| WMTP | OPC 40505, 1.0.0 | Bundled in MachineTool; distinct CLR/wire
namespace and independent WMTP-only hosting |
| GMS | OPC 40210 reference 1.0.1, normative model 1.0.0 | Model,
Server, Client and MCP; normal root versions |
| CranesHoists | OPC 40020-1, 1.00 | Model, Server, Client and MCP; all
four plus Debug variants forced preview |

There are **12 new packable projects**. No separate WMTP
package/profile/guide, root version bump, tag, release or package
publication is included. Mandatory instance structure is the default;
selected optional features require explicit providers. The
implementation reuses Machinery results/jobs/files/ProcessValues and
Robotics topology, including retained MachineTool Production, defined
GMS jobs/parts, modern ISA95/Machinery jobs, shared-owner hosting and
isolated instances alongside MachineVision.

Runtime and integration fixes preserve raw quality/timestamps, coherent
acquisition, namespace ownership, accepted-configuration state,
borrowed-resource lifetime, session/node/file cleanup, terminal-value
publication, event propagation and endpoint-aware capability
publication. Firmware/licence transfer means provider acceptance, not
installation/activation. Cancellation does not silently abort another
caller's operation. The later upstream MCP expansion is integrated
without losing either family set or its default-off privileged/live
execution policy.

### Conformance and scope

Canonical model inputs are pinned to UA-Nodeset revision
`96a08945425d0295edb3607d2a38f6841ef44046`.

**GMS upstream exception:** [Annex
A.1](https://reference.opcfoundation.org/specs/OPC-40210/annex-a) makes
the released NodeSet normative, but §12.3.2.7 requires undefined
`GMS_ProductionStatisticsType`. Inherited statistics and defined
jobs/parts are implemented without inventing a standard type/NodeId; the
complete GMS Production facet is withheld.

The requirement ledger records **102 positively evidenced CU rows, 96
directly negative-tested rows and six explicit negative-evidence
limitations**. All 648 test-class/name/TRX links were independently
resolved to passing cases. The six limitations concern Stacklight,
retained legacy PowerOnDuration, Machinery PowerOnDuration, WorkingUnit,
Obligation and MaintenanceMode. They are not claims that every
invalid-input or hardware-control behavior was tested. The undefined GMS
requirement is outside the 102 defined CUs. No external certification
claim is made.

Retained baseline complete-assembly line coverage, with generated code
retained and no source exclusions:

| Family | Model | Server | Client |
| --- | ---: | ---: | ---: |
| MachineTool/WMTP | 83.80% | 91.98% | 84.74% |
| GMS | 95.51% | 90.63% | 88.38% |
| CranesHoists | 92.76% | 94.45% | 92.24% |

These nine measurements predate the later focused review fixes and
merges; they are not relabelled as new `ecc4a7d6c` percentages. The
current head's separate CI code-coverage check succeeded. No new
exclusions or threshold relaxations were introduced.

Marc Schier 724757122b Add recycling simulator and plastics/rubber companion packages (#4772)
# Description

Add a generic, company-neutral recycling simulation sample and reusable
plastics/rubber companion-model packages. One durable causal coordinator
and ten separately launched OPC UA process views provide deterministic
material balances, finite buffers, genealogy, utilities, quality
holds/disposition, authenticated controls and crash recovery. Process
views consume committed state instead of running independent
simulations.

Real companion-model equipment instances use DI/Machinery/AMB discovery,
Machine Vision, Pumps/Scales, granulate drying, extrusion, filtration
and pelletizing. Vendor/process extensions remain sample-local.
Connectors and WoT conversion are out of scope. **External
source-contract parity and complete deployment qualification are not
claimed complete.**

The sample and managed tests target **.NET 8, 9 and 10**. The
consolidated [recycling guide](samples/Recycling/README.md) explains the
actual composition, simulation, observation paths and exposed data; the
application-directory README points to that guide.

Typed client member extensions are emitted at build time through the
default-false `ModelSourceGeneratorClientAccessorsOnly` opt-in.
Extrusion uses it for all twelve parts instead of checked-in generated
C# and a Python generator. The shared client runtime retains typed
values, quality, timestamps and streaming behavior.

### Package layout

Six packages contain fourteen models in two model-producing assemblies:

| Specifications | Model | Typed client | Server runtime |
| --- | --- | --- | --- |
| OPC 40083 and OPC 40082-6 | `Opc.Ua.PlasticsRubber` |
`Opc.Ua.PlasticsRubber.Client` | `Opc.Ua.PlasticsRubber.Server` |
| OPC 40084 parts 1–12 | `Opc.Ua.Extrusion` | `Opc.Ua.Extrusion.Client`
| `Opc.Ua.Extrusion.Server` |

NuGet IDs use the `OPCFoundation.NetStandard.` prefix. All six packages
are registered in `.azurepipelines/expected-packages.txt` and the
generated preview-pack solution. Granulate-drying code lives in
`GranulateDrying` folders in the PlasticsRubber projects; extrusion uses
per-part folders. There are no standalone granulate-drying or per-part
extrusion packages. Published model identities and CLR namespaces remain
distinct and unchanged.

The common 1.03 interface is independently authored on the explicitly
MIT-licensed 1.02 implementation basis; the official 1.03 XML is not
redistributed. The other imported models retain their individual MIT
notices. All 42 pinned model, identifier and basis files retain their
manifest-backed bytes, including their staged Git blobs. No formal
companion certification is claimed; the disputed Filter profile is not
advertised.
