Source generator: keep NodeSet2 references to nodes of referenced models (#4796)
# Description A reference in a NodeSet2 input whose target is a node of another model was dropped without a diagnostic when that model is supplied by a referenced assembly rather than by an AdditionalFiles input. The dependency metadata of a referenced assembly carries types only, so the importer could not resolve an instance such as DI's DeviceSet and skipped every reference to it: a device organized by DeviceSet (inverse Organizes) lost that reference, and so did any non-hierarchical reference to such a node. When the target of a reference is in another, non-zero namespace and no loaded design defines it, the importer now creates a stand-in that carries only the NodeId the generated AddReference call needs. The stand-in is not generated. References whose reference type is unknown are still skipped. Tests generate a DI-style NodeSet2 whose device is organized by DeviceSet against DI supplied as a referenced assembly and as an AdditionalFile, and compile the result against the stack. ## Related Issues None. ## Checklist - [x] I have signed the [CLA](https://opcfoundation.org/license/cla/ContributorLicenseAgreementv1.0.pdf) and read the [CONTRIBUTING](https://github.com/OPCFoundation/UA-.NETStandard/blob/master/CONTRIBUTING.md) doc. - [x] I have added tests that prove my fix is effective or that my feature works and increased code coverage. - [x] I have added all necessary documentation. - [x] I have verified that my changes do not introduce (new) build or analyzer warnings. - [x] I ran **all** tests locally using the **UA.slnx** solution against at least .net **framework** and .net **10**, and all passed. - [x] I fixed **all** failing and flaky tests in the CI pipelines and **all** CodeQL warnings. - [ ] I have addressed **all** PR feedback received. --------- Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> Co-authored-by: Marc Schier <marcschier@users.noreply.github.com> |

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. ## Related Issues - Fixes [#4764](https://github.com/OPCFoundation/UA-.NETStandard/issues/4764), the implementation/design and acceptance tracker. ## Checklist _Put an `x` in the boxes that apply.

Implement OPC UA Part 10 Programs (#4789)
# Description Implement OPC UA Part 10 Programs across `Opc.Ua.Core`/`Core.Types`, `Opc.Ua.Server`, and `Opc.Ua.Client`, reusing the existing state-machine, source-generation, node-management, auditing, and streaming-subscription infrastructure. - Add asynchronous provider-backed execution, standard controls, internal/autonomous transitions, generation checks, and nested-state activation/resumption. - Add checked creation/adoption, vendor Create adapters, deletion, recycling and instance limits, auto-delete, DI, and direct-construction paths. - Maintain ProgramDiagnostic2 and retained final results; publish captured intermediate results and concrete transition/audit events with access controls. - Add generated SDK models/proxies, typed client discovery and reads, event streams, and subscribe-before-call readiness handling. - Add unit, connected client/server, generated Annex A-style model, and NativeAOT coverage. Document usage and migration in `docs/Programs.md` and related guides. ### Compatibility and design decisions The linked Part 10 document is v1.05.00; namespace-zero definitions remain aligned with 1.05.07. Documentation distinguishes normative requirements from conflicting specification text and SDK conventions. - Correct state numbers to Halted=11, Ready=12, Running=13, Suspended=14. Generated subtypes retain inherited namespace-zero state/transition identifiers. - Managed Reset is Halted-to-Ready only. Preserve the existing low-level Reset-from-Suspended behavior for compatibility. - Preserve UInt32 limit types; use `UInt32.MaxValue` as a documented SDK unlimited convention. RecycleCount overflow reports BadOutOfRange without stopping unlimited execution. - In-memory default with injectable providers. Durable recovery, distributed execution/failover, and a production Annex A download engine are excluded. ## Checklist _Put an `x` in the boxes that apply. You can complete these step by step after opening the PR._ - [ ] I have signed the [CLA](https://opcfoundation.org/license/cla/ContributorLicenseAgreementv1.0.pdf) and read the [CONTRIBUTING](https://github.com/OPCFoundation/UA-.NETStandard/blob/master/CONTRIBUTING.md) doc. - [ ] I have added tests that prove my fix is effective or that my feature works and increased code coverage. - [x] I have added all necessary documentation. - [x] I have verified that my changes do not introduce (new) build or analyzer warnings. - [ ] I ran **all** tests locally using the **UA.slnx** solution against at least .net **framework** and .net **10**, and all passed. - [ ] I fixed **all** failing and flaky tests in the CI pipelines and **all** CodeQL warnings. - [ ] I have addressed **all** PR feedback received. Tests and focused coverage evidence are above; the combined tests/coverage checkbox remains open because a whole-repository coverage increase has not been established. CLA status, CI/CodeQL results, tracking-issue approval, and PR feedback are not asserted. |

Add Machine Vision Parts 1 and 2 (#4733)
# Description Implement the released [OPC 40100-1](https://reference.opcfoundation.org/specs/OPC-40100-1) and [OPC 40100-2](https://reference.opcfoundation.org/specs/OPC-40100-2) specifications with generated models, provider-backed runtimes, typed clients, MCP workflows, and DI/Machinery integration. - **Part 1 stays in `Opc.Ua.Vision`** and its client/server packages alongside the distinct Perception model. Provide control/acquisition state machines, jobs and synchronized steps, recipe/product/configuration/result management, file transfers, diagnostics, events, and conditions. - **Part 2 is in `Opc.Ua.MachineVision`, `.Client`, and `.Server`.** Provide asset categories, identification, image-handling aspects, health/maintenance data, topology, and transactional updates. The base Vision assemblies do not reference these optional packages; the Part 2 wire model does not depend on Part 1. - Preserve the release-pinned model bytes, wire namespaces and NodeIds. Perception types are in `Opc.Ua.Vision.Perception`; the AMCM generated namespace remains `Opc.Ua.Vision.MachineVision.AMCM`, and asset client/server extension namespaces remain `Opc.Ua.Vision.Client` and `Opc.Ua.Vision.Server`. - Use `AddOpcUaMachineVision` and `AddOpcUaMachineVisionAMCM` for model loading and factory registration. Each has node-collection, encodeable-factory-builder and node-state-factory-builder overloads. These short entry points delegate to the generated implementations; existing namespace-derived generated names remain available for compatibility. - Support multiple independent named systems/assets under one namespace-owning manager. Reuse injectable providers, file binding, bounded memory stores, optional transactional `IFileSystemProvider` persistence, state machines, telemetry and conformance infrastructure. - Keep one `docs/Vision.md` guide, titled `Machine Vision (OPC 40100-1 and OPC 40100-2)`, and one `Opc.Ua.Mcp.Vision` package. Include deterministic server/client samples. - Expose 17 Machine Vision MCP tools, including capabilities/status, bounded relationships and observation, complete small-file uploads/downloads, management, explicit control, conditions, and chunked transfers. Catalogue counts: 39 Vision-specific, 43 with connection tools, 81 Vision+Robotics, 155 Full. Every Machine Vision wire parameter has a schema description. **Compatibility and limits:** `AddVision()` remains Perception-only unless released parts are selected. Standalone Part 2 uses `AddVision().AddMachineVision()`; Machinery composition uses `AddVisionToMachinery()`. Existing tool defaults and command signatures are preserved. Observation owns and cleans up its subscription: 5 seconds/50 notifications by default, capped at 60 seconds/100 notifications. Complete-file tools are capped at 1 MiB; larger files use chunked transfers. Domain Error values remain distinct from UA service failures. **Versioning:** the seven Vision/MachineVision/MCP packages and their Debug variants follow the repository root version instead of being forced to preview. Vision.OpenUsd and its descendants remain preview-only. Development builds still inherit the root prerelease version. No release version, tag, release branch, publication policy, or feed promotion is changed. **Review actions:** all fourteen review threads have action/evidence replies and are resolved. Changes include the unified guide, Perception namespace, separate Part 2 packages and final naming, multi-system ownership explanation, interrupted-write cleanup, observer failure isolation, complete MCP parameter descriptions, and explicit package inventory. The preview-layout migration topic and the requested ReleaseProcess caveat were removed. The test Publish collector now retries recognized transient failures within one cancellation budget and propagates other exceptions. Commit |

Enable nullable reference types centrally; migrate all unset and annotations-only projects (#4700)
# Description Nullable reference types are now enabled once, in `common.props`, and every project in the repository builds warning-clean with them. **Configuration** - `<Nullable>enable</Nullable>` lives in `common.props`. All per-project `<Nullable>` settings are removed: 178 project files (enable, annotations, and the `disable` in the three Aot test projects). - 419 per-file `#nullable enable`/`restore` directives and the 4 `#nullable disable` directives are removed. - Kept on purpose: - The 5 `<auto-generated>` schema files (`UANodeSet.cs`, `UA Type Dictionary.cs`, `OPCBinarySchema.cs`, `SecuredApplication.cs`, `PInvokeHelper.cs`) keep `#nullable enable`. The compiler ignores the project setting in generated code, so the directive is required there. - `tests/Opc.Ua.Interop.LegacyPeer` keeps `disable`. It builds against the 1.5.378 packages and does not import the repository props. - `docs/DeveloperGuide.md` and `.github/copilot-instructions.md` now describe the central setting. **Migration** (the 43 unset and 13 annotations-only projects, roughly 10k diagnostics) - **Production code: annotated at the declarations.** Covers `tools/Opc.Ua.SourceGeneration.Core`, `src/Opc.Ua.Lds.Server` and the LDS sample. - Members, parameters and returns are nullable where null actually flows. - Null-check helpers carry `[NotNullWhen]` (`IsNull`, `IsValidXmlName`, `IsMethodTypeDesign`). - `CoreUtils.Format`, `Utils.Format`, `ITemplateWriter.WriteLine` take `params object?[]`. `Template.AddReplacement` takes `string?` (rendering already skips null replacements). - `IRegisteredServerStore.RegisterAsync` returns `Task<RegistrationEntry?>`: it returns null when a registration is removed. - Dereferences backed by an invariant (for example, the validated model) use `!`, so runtime behaviour is unchanged. - **Behavioural changes in production code** (small, deliberate): - `NodeSetToModelDesign` throws `InvalidOperationException` when the file is not a NodeSet. Before, it threw a NullReferenceException on the next line. - `ModelDesignValidator` starts its lookup tables empty instead of null. A redundant `if (m_nodes == null) return;` guard is gone. - **Test code: minimal annotations.** - `?` on values that can be null, `!` where the test asserts non-null. - `= null!` for fixture members assigned in SetUp. - `TryGetStructure<T>(out T? x)` where the inferred `T?` broke the `IEncodeable` constraint. - A few redundant `== null` checks on structs (`NodeId`, `ArrayOf<T>`) folded into the adjacent `IsNull`/`Count` checks. **Notes for reviewers** - The diff is large (~1,500 files) but almost entirely mechanical: `?`, `!` and directive removal. The non-annotation changes are listed above. - Known follow-up, not done here: `IModelDesign.Namespaces/TargetNamespace/NamespaceUris` stay non-nullable even though the validator returns null before it loads a dictionary. Making them nullable would ripple through every generator call site. ## Related Issues - Fixes #4439 ## Checklist - [ ] I have signed the [CLA](https://opcfoundation.org/license/cla/ContributorLicenseAgreementv1.0.pdf) and read the [CONTRIBUTING](https://github.com/OPCFoundation/UA-.NETStandard/blob/master/CONTRIBUTING.md) doc. - [ ] I have added tests that prove my fix is effective or that my feature works and increased code coverage. - [x] I have added all necessary documentation. - [x] I have verified that my changes do not introduce (new) build or analyzer warnings. - [ ] I ran **all** tests locally using the **UA.slnx** solution against at least .net **framework** and .net **10**, and all passed. - [ ] I fixed **all** failing and flaky tests in the CI pipelines and **all** CodeQL warnings. - [ ] I have addressed **all** PR feedback received. The "no new warnings" box covers net10.0 and net48: full non-incremental builds of `UA.slnx`, `tools/SourceGeneration.slnx`, `tools/MigrationAnalyzer.slnx` and the Aot test projects finished with 0 warnings and 0 errors under the repository's warnings-as-errors settings. net9.0 and net8.0 also had no nullable diagnostics, but they were not rebuilt after the final fixes.

CTT: keep GeneratesEvent off Object instances and Views off non-hierarchical references; classify Deadband Err-006 as CTT defect (#4667)
# Description Three findings from the 2026-10-03 CTT run with the patched 1.05.513 scripts. Two are server/model defects and are fixed here. The third is a CTT script defect, recorded as C56 in `plans/ctt-issues.md`. ## 1. Monitored Items Deadband Filter `Err-006.js`: CTT defect (C56, no server change) The script modifies a MonitoredItem on the first static numeric scalar (a plain BaseDataVariable with no EURange) to use a PercentDeadband. It accepts only `Good` or `Bad_MonitoredItemFilterUnsupported`. Since #4629 the server returns `Bad_DeadbandFilterInvalid`, and that is the code the spec defines for this case: - OPC 10000-8 §7.2: PercentDeadband "applies only to AnalogItems with an EURange Property". - OPC 10000-8 §7.3.2 Table 61: `Bad_DeadbandFilterInvalid` is returned when "a PercentDeadband is not supported, since an EURange is not configured". CreateMonitoredItems and ModifyMonitoredItems both go through `ValidateMonitoringFilterAsync` and return the same code. Monitor Basic `Err-022.js` already accepts `Bad_FilterNotAllowed` for non-analog items, so the scripts disagree with each other here. Draft Mantis note (not filed yet): > **Monitored Items Deadband Filter Err-006.js rejects Bad_DeadbandFilterInvalid for a PercentDeadband on a node without EURange** > Err-006.js picks the first node of `/Server Test/NodeIds/Static/All Profiles/Scalar/NumericSettings`, which is normally a BaseDataVariable without an EURange. It then calls ModifyMonitoredItems with a PercentDeadband (10 %) and accepts only Good or Bad_MonitoredItemFilterUnsupported. OPC 10000-8 §7.2 limits PercentDeadband to AnalogItems with an EURange. §7.3.2 Table 61 defines Bad_DeadbandFilterInvalid for "a PercentDeadband is not supported, since an EURange is not configured", so a compliant server fails this test. Monitor Basic Err-022.js already accepts Bad_FilterNotAllowed for the non-analog fallback. > Proposed fix: add StatusCode.BadDeadbandFilterInvalid (and, consistent with Err-022.js, StatusCode.BadFilterNotAllowed) to the ExpectedAndAcceptedResults of the ModifyMonitoredItems call. ## 2. GeneratesEvent on Objects (Base Info Core Structure 2 `001.js`): source generator defect The CTT reported `ns=9;i=234` (the `<ServiceName>` placeholder of AuthorizationServicesFolderType) and `ns=9;s=AuthorizationServices/Default` as Objects that are the source of GeneratesEvent references. OPC 10000-3 §7.15 says: "The SourceNode of References of this type shall be an ObjectType, a VariableType or a Method". `OpcUaGdsModel.xml` declares both references (AccessTokenRequested/Issued audit events) correctly, on `AuthorizationServiceType`. The source generator copied the type's own non-hierarchical references onto every Object or Variable built from the type: onto instance declarations (the placeholder) and into `CreateInstanceOf<Type>`, which `AuthorizationServiceState` initialises from, and that is how the `Default` service gets them. UA-ModelCompiler does the same thing, so the official `Opc.Ua.Gds.NodeSet2.xml` in UA-Nodeset has the same two references on `ns=1;i=234`. Fix: - `TranslateReferences` now marks references declared on a type (`HierarchyReference.DefinedOnType`, which already existed but was never set). - `NodeStateGenerator.GetReferences` drops forward GeneratesEvent references (including subtypes such as AlwaysGeneratesEvent) for Object and Variable nodes when the reference came from the type. - ObjectTypes, VariableTypes and Methods keep these references. For example, the RegisterApplication methods and the Acknowledge/AddComment methods of the alarm types are unchanged. - References that a model declares explicitly on an instance are emitted as before. ## 3. View targeted by HasCause/HasEffect (Base Info Core Structure 2 `001.js`): sample model defect #4485 added `Views_Operations HasCause/HasEffect Views_Engineering` so that View Minimum Continuation Point 01 `012.js` and View Basic 2 `018.js` have at least two references to View nodes on the configured View (`/Server Test/NodeIds/NodeClasses/View` = `Views_Operations`). OPC 10000-3 §5.4 says Views "can be the SourceNode of any hierarchical Reference. They shall not be the SourceNode of any NonHierarchical Reference." `Views_Operations` now Organizes `Views_Engineering` and a new View, `Views_Maintenance`, which organizes `DataAccess`. This keeps two View-class references and adds no loops (ContainsNoLoops stays true). ## Tests - `NodeStateGeneratorTests.TypeGeneratesEventReferencesAreNotCopiedToObjectInstances`: covers the type, the placeholder, the instance, `CreateInstanceOf`, Methods and an explicit instance reference. It fails without the fix. - `ReferenceServerTest.SampleViewsHaveNoNonHierarchicalReferencesAsync`. The existing `NodeClassSampleNodesReferenceTheirOwnNodeClassAsync` still passes. - Results with net10.0: - SourceGeneration.Core.Tests: 4267 passed, 0 failed - InformationModel.Tests: 1078 passed, 0 failed - Di.Tests, including RobotOpenUsdE2e: 438 passed, 0 failed - OpenUsd.Tests: 921 passed, 0 failed - Server.Tests `ReferenceServerTest`: 56 passed, 0 failed - `UA.slnx` builds with net10.0. The changed test projects build with net48. ## CTT (patched 1.05.513 scripts, compared with the 2026-10-03 patched baseline) | Part | Change | | --- | --- | | p02-base-info | Base Info Core Structure 2 `001.js`: Error → Skipped. The GeneratesEvent and View errors are gone; the remaining skips are the CTT's own "type not defined within the test-script" notes. No other change. | | p03-base-view-method | No change. View Basic 2 `018.js` and View Minimum Continuation Point 01 `012.js` still pass. | | p13-monitored-items | Deadband `Err-006.js` still Error (C56). With the script fix it passes. Monitor Basic `007.js` gave a response-timestamp delay warning (>200 ms) caused by machine load; it also appears in the 2026-09-29 base run. | 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com> |

Remove netstandard2.1 and net472 target frameworks (#4624)
# Description Drops support for **netstandard2.1** and **.NET Framework 4.7.2**. Libraries now target `net48`, `net8.0`, `net9.0` and `net10.0`. `Opc.Ua.Types` and `Opc.Ua.SourceGeneration.Core` still also target `netstandard2.0`, but only because the Roslyn source generators load them. There is no general netstandard2.0 support. **Preprocessor directives** (112 files) - Every `#if`/`#elif` mentioning `NETSTANDARD2_1*`, `NET472*`, `NET_STANDARD_TESTS`, `SKIP_ECC_CERTIFICATE_REQUEST_SIGNING` or `NETSTANDARD*` was evaluated against the remaining TFM set (net48, net8/9/10, plus netstandard2.0 inside `Opc.Ua.Types`/`tools`) and simplified. Dead branches were removed. - Example: `NETSTANDARD2_1 || NET8_0_OR_GREATER` → `NET8_0_OR_GREATER`. - Example: `NET8_0_OR_GREATER || NET472_OR_GREATER` → removed (always true). - Netstandard-only code was removed: `UnixFileModeShim`, the CRDT reflection path in `ReplicatedGossipOptions.CreateReaderOptions`, and the netstandard2.1-only test variants. **Custom test logic** - `targets.props` drops the `net472`, `netstandard2.0` and `netstandard2.1` `CustomTestTarget` profiles, `NetStandardTests` and `SKIP_ECC_CERTIFICATE_REQUEST_SIGNING`. Supported values are now `net48`, `net8.0`, `net9.0`, `net10.0`. - The `NET_STANDARD_TESTS` define is removed from 29 test projects. - The "build netstandard shells as net10.0" overrides are removed from 18 projects. - `RestrictForLegacyTfm` now only applies to `net48`. - `tests/customtest.bat` is updated to the new values. **Build / packaging / CI** - MSBuild TFM conditions are simplified: Kestrel package choice, MQTTnet v4 (net48 only), BouncyCastle, Di/OpenUsd/Vision/Stress test excludes, and `System.IO.FileSystem.AccessControl` (dropped from Core). - The MigrationAnalyzer nuspec drops its net472/netstandard2.1 lib groups. The Azure signing lists are updated. - `get-ci-matrix.ps1` removes the net472/netstandard test profiles (including the PR-gating `linux-netstandard2.1`) and the matching build legs. **Breaking API change (2.0 preview):** removed `HttpsTransportListener.IsWssTransportSupported` and `ReplicatedGossipOptions.IsGossipStateDecodingSupported`. They only returned `false` on netstandard2.1 and are now always `true`. The test guards that used them were removed as well. **Docs** - NuGet READMEs, `README.md`, `DeveloperGuide.md`, `PubSub.md`, the certificate/ECC/identity docs and the 2.0 migration guide (plus its `.agents` skill mirror) are updated. - The migration guide notes that 4.7.2 consumers must move to 4.8 and netstandard2.1 consumers to net8.0+. ### Reviewer notes - The `System.IO.FileSystem.AccessControl` `PackageVersion` pin is left in `Directory.Packages.props`. It has no direct reference any more, but transitive pinning is on, so it was kept to avoid shifting resolved versions. - The `#if` rewrite was done mechanically by a truth-table evaluator. The diff in the `.cs` files is limited to directive lines, removed dead branches, and stale-comment updates. ### Verified locally - `dotnet build UA.slnx -p:CustomTestTarget=net48`: 0 errors. - `dotnet build UA.slnx -p:CustomTestTarget=net10.0`: 0 errors. - Default multi-target builds (no `CustomTestTarget`) of Opc.Ua.Types, Bindings.Https, PubSub.Mqtt and Redundancy.Server succeeded. - net10.0 tests: - Opc.Ua.Redundancy.Server.Tests: 840/840 passed. - Opc.Ua.Types.Tests: 11363 passed, 1 skipped. - ModelDependencyScanner tests: 20/20 passed. - The full test suite was **not** run locally. ## Related Issues - None ## Checklist - [ ] I have signed the [CLA](https://opcfoundation.org/license/cla/ContributorLicenseAgreementv1.0.pdf) and read the [CONTRIBUTING](https://github.com/OPCFoundation/UA-.NETStandard/blob/master/CONTRIBUTING.md) doc. - [ ] I have added tests that prove my fix is effective or that my feature works and increased code coverage. - [x] I have added all necessary documentation. - [ ] I have verified that my changes do not introduce (new) build or analyzer warnings. - [ ] I ran **all** tests locally using the **UA.slnx** solution against at least .net **framework** and .net **10**, and all passed. - [ ] I fixed **all** failing and flaky tests in the CI pipelines and **all** CodeQL warnings. - [ ] I have addressed **all** PR feedback received. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com> |

Source generator, ISA-95 Job Control and DI changes for companion SDKs built on referenced models (#4577)
## Summary First of four stacked PRs that contribute complete implementations of the Machinery (OPC 40001-1 with Job Management, Result Transfer, Process Values and Energy), Pumps (OPC 40223) and Scales (OPC 40200, with PackML OPC 30050) companion specifications — tracked in #4576. It follows the split used for Robotics (#4123–#4127): this PR carries only the changes to **existing shared code** those SDKs need, and adds no project. Each change stands on its own and is covered by tests in this PR; the companion models are what surfaced them. Rebased onto master after #4569. The one conflict was in `NodeSetToModelDesign.cs`: #4569's shared `AssignSymbolicIds` already makes `Import` and `GetImportedSymbols` derive the same ids, and `NormalizeParentNodeId` moves into its pre-pass. The Copilot review is addressed in the last six commits (see "Review follow-up"). ## Changes ### Source generator (`tools/Opc.Ua.SourceGeneration.Core`) - **VariableType data type across assemblies.** A model that consumes a dependency through a referenced assembly's `[ModelDependency]` payload lost a VariableType's `DataType`/`ValueRank`, so `GetNodeStateClassName` dereferenced null and reported `MODELGEN003`. First hit: DI's `LifetimeVariableType` as used by Machinery. - **Method declaration ↔ method state identity.** A consumer re-declaring an inherited method referenced an `OwnerType_MethodMethodState` class the producer never generated. First hit: OPC 34100 ECM re-declaring the DI `LockingServices` methods. - **Browse names and reference types of inherited children.** An inherited child was emitted with `ReferenceTypeId = NodeId.Null` (invisible to a filtered Browse over the wire) and, where it lives in another namespace, with the declaring model's namespace. When the carried namespace is one the consuming model does not declare, the generated code names it by URI instead of emitting an empty `GetIndexOrAppend()`. - **Payload compatibility.** The three additions above travel in a length-prefixed, versioned declaration trailer after the existing trailers, so the node and child records keep their layout: an older reader ignores the capability bit and stops after the trailers it knows, and a payload without declarations is byte-identical to before. - **Symbolic ids of children listed before their parent.** Every `ParentNodeId` is normalized before any symbolic id is derived. No NodeSet in the repository has such an ordering today, so no generated symbol changes; OPC 30050 PackML (later in the stack) declares seven method `InputArguments` before their methods and failed with `MODELGEN025`. - **Methods overridden with another method-state class.** The subtype declares its own field and property for such a method, but `GetChildren` and `RemoveExplicitlyDefinedChild` skipped every overridden child and the supertype's field stays empty, so the method was missing from every instance (not browsed, no per-instance NodeId, not callable). The existing `MethodTypeOverride` test model has the gap; since #4555 generates a method with inline arguments as `MethodState`, OPC 40001-101 `ResultTransferType.GenerateFileForRead` hits it. It also affects models already in the repository: DI `SoftwareFolderType.Delete`, ISA-95 V2 `JobOrderReceiver.Update`, WoTCon `WoTDocument.Validate` and XRegistry `Group.Delete` / `Resource.Delete` now appear on their instances; the DI, ISA-95, WoTCon and XRegistry tests pass. ### ISA-95 Job Control (`src/Opc.Ua.ISA95.Server`) - **`Isa95JobControlV2Binder`** — the V2 receiver/response-provider binding moves out of `Isa95NodeManager` so OPC 40001-3 JobManagement can bind the same eleven verbs on its own instances instead of copying them. `Isa95NodeManager` behaviour is unchanged. - **`Isa95AddressSpaceOwnership`** — a second registration that would load the ISA-95 models fails immediately and names the current owner, as `DiAddressSpaceOwnership` already does for DI. - **`IIsa95JobResponseCatalog`** — a source for `JobOrderResponseList`, which the two state-filtered request methods cannot express. - **`IIsa95JobResponseChangeSource`** — a change stream of received responses, and of responses the provider drops after `ResponseRetention`; a response changes neither the order's state nor the order catalog, so the existing streams cannot report it. Both interfaces are implemented by `InMemoryIsa95JobControlProvider`, registered by `AddInMemoryIsa95JobControlProvider`, and count in `AddIsa95Server`'s provider detection and mixed-provider rejection. ### Device Integration (`src/Opc.Ua.Di.Server`, `src/Opc.Ua.Di.Client`) - **`IDiPostSetupContext.GetService<T>()`** — an optional lookup next to `GetRequiredService<T>()`, so a companion SDK can probe for a seam the server may not have filled without catching `InvalidOperationException`. The context still exposes no raw `IServiceProvider`. - **`DiNodeManager.ConformanceUnits` / `ServerProfiles` are virtual**, so a companion subclass appends the units its own model satisfies. - **DI client browse enumerators follow `BrowseNext`.** `DiTopologyClient.BrowseChildrenAsync` and `DiDeviceClient.BrowseFunctionalGroupsAsync` discarded the continuation point and returned an incomplete list from a paginating server. A bad status for the browsed node still means "no children" and a failed service call propagates; an outstanding continuation point is released whenever the enumeration stops early. ## Review follow-up | Copilot finding | Commit | |---|---| | Payload additions break older readers (both High) | `fix(sourcegen): move the dependency declarations into a trailer` | | Browse failures reported as empty, broad exception filter (Medium ×2); missing pagination tests (Low ×2) | `fix(di-client): let a failed browse call propagate` | | New provider facets missing from detection (Medium) | `fix(isa95): count the response facets as Job Control providers` | | Second review: continuation point kept after a failed BrowseNext | `fix(di-client): release the continuation point after a failed BrowseNext` | | Second review: purged responses not reported | `fix(isa95): report dropped job responses on the response change stream` | | Second review: missing V2 namespace cast to 65535 | `fix(isa95): reject a missing Job Control V2 namespace in the binder` | ## Points for the reviewer - `GetService<T>()` adds a member to a public 2.0 interface. The only implementation is the internal `DiPostSetupContext`; an external implementer would have to add it. - `DiDeviceClient.BrowseFunctionalGroupsAsync` used to throw for a bad status of the device node; like `DiTopologyClient` it now yields nothing. - The commits are self-contained and ordered; reviewing commit by commit is the easiest route. ## Testing - New and extended tests: `ModelDependencyV1Tests`, `NodeStateGeneratorTests`, `NodesetIdentifierSidecarTests`, `InMemoryIsa95JobControlProviderV2Tests`, `Isa95ServerBuilderTests`, `Isa95JobControlV2BinderTests`, `DiDeviceClientTests`, `DiTopologyClientTests`, `OpcUaServerDiBuilderExtensionsTests`. - `UA.slnx` builds for net472, net48, netstandard2.0/2.1 and net8/9/10 with SDK 10.0.401 and no warnings. - Tests on net10: SourceGeneration.Core 4266 (8 skipped), SourceGeneration 263, ISA95 144, DI 433; the first three also on net8. The changed projects build for net48 and netstandard2.0 without warnings. - Changed-line coverage (`check-coverage.ps1`): 91.1 % (594 of 652 lines). - The companion stack on top (#4578, #4579, #4580) is rebased onto this head. - Fork CI, full PR matrix incl. macOS, for this head (running): https://github.com/biancode/UA-.NETStandard/actions/runs/36558506011. CodeQL: https://github.com/biancode/UA-.NETStandard/actions/runs/36558509242. The previous head (before the second review round) passed every Windows and Linux job: https://github.com/biancode/UA-.NETStandard/actions/runs/36542929585. |

Fix source generator audit findings; conform structure-field matrices and type metadata to OPC UA 1.05 (#4569)
# Description
This PR fixes a bug audit of the source generation projects
(`tools/Opc.Ua.SourceGeneration*`: model loading, NodeSet import, all
emitters, the Roslyn hosts and packaging). It also fixes a max-effort
code review of those fixes, and a check of every spec-relevant change
against the OPC UA 1.05 text.
- **Scope:** about 85 audit findings, 48 review findings and 32
spec-grounding items were addressed. Each fix has a regression test that
fails without it.
- **Wire change:** it includes one deliberate, stack-wide wire change:
**structure-field matrices now follow OPC 10000-6 5.2.5 Table 28**.
Most changes are internal correctness fixes. The sections below list
every change a user can observe: wire formats, generated code and API,
generated address-space content, diagnostics and runtime behaviour.
## Behaviour / user-facing changes
### Wire format (encoders)
- **Binary inline matrices** (OPC 10000-6 5.2.5 Table 28).
- **Layout:** a multi-dimensional *structure field* is encoded as
`Int32[] Dimensions`, then the values **without a length prefix**, with
at least 2 dimensions.
- **Empty and null:** any dimension <= 0 means no values follow, and a
null matrix is `-1`. An empty matrix is written as `[0,0]`.
- **Compatibility:** this is **not compatible with earlier builds of
this SDK** for matrix fields. It applies to generated types,
`[DataType]` types, `Structure`, client ComplexTypes and
`WriteEncodeableMatrix`.
- **Unchanged:** Variant matrices (5.2.2.16) keep their old encoding.
- **Declared rank decides matrix vs array.** A 1-D `MatrixOf<T>` in an
array field or a Variable value is written as an array again.
Matrix-declared fields go through the new public
`EncoderExtensions.WriteInlineMatrixValue`, which generated code also
uses. A non-empty 1-D value in a matrix field throws `BadEncodingError`.
- **Decoder hardening:**
- Before allocating, the decoder bounds all matrix dimensions against
overflow, `MaxArrayLength` and the remaining message length.
- The decoder rejects:
- a matrix with fewer than 2 dimensions;
- a populated matrix whose rank differs from the field's declared rank;
- a union SwitchField greater than the number of fields;
- an EncodingMask with unassigned bits set.
- **Encoder `MaxArrayLength`:** the encoder enforces `MaxArrayLength`
for inline matrices, as it already did for arrays.
- **XML structure fields** (5.3.1, 5.3.4, 5.3.5).
- **Fields:** `Structure` and client ComplexTypes write fields like
typed fields (`<A>1</A>`, array elements directly) instead of a Variant
body.
- **Matrix fields:** `Dimensions` and `Elements` go directly inside the
field element, with no `<Matrix>` wrapper.
- **Empty matrices:** written as nil, because XML dimensions must be
greater than 0.
- **Compatibility:** decoders still accept the old shapes.
- **Enum fixes:** enum array elements with value 0 are no longer
dropped, and enum array element names are fixed.
- **Other encoding fixes:**
- A null `DiagnosticInfo` structure field writes `0x00` instead of
nothing.
- A null scalar field in a runtime `Structure` is written as its default
instead of zero bytes, which used to shift every following field.
- A Variant holding an empty matrix encodes as an empty array instead of
throwing.
- `Variant.Copy` keeps the matrix identity of null and empty matrices.
- **NodeSet export and the DataContract surrogate** write Variable
values with the Variant rules again. A null or empty `MatrixOf` variable
no longer produces invalid XML or unreadable NodeSets.
- **`JsonEncoder.CanOmitFields`** is `true` only for Compact encoding.
Verbose and RawData JSON include default-valued fields.
### `[DataType]` source-generated types
- **Default-value handling** (OPC 10000-6 5.4.1, Table 1).
- **Encode:** a field is omitted only when its value *and* its declared
default are the type's default (0, false, null). Fields with a
non-default initializer or constructor default, and empty strings, are
always written, so configuration files get slightly larger.
- **JSON decode:** a field missing from JSON decodes to the type
default.
- **XML decode:** a field missing from XML keeps its declared default,
which older configuration files rely on.
- **Why:** this fixes silent round-trip loss, for example
`SamplingInterval = 0` read back as `-1`.
- **Nested `[DataType]` types:** they are now generated inside their
containing types. Without an explicit id, their default TypeId and
XmlName are qualified (e.g. `s=Outer.Foo`); **wire identity change** for
nested types. Colliding activator names get a `_2` suffix.
- **Activators:** they are `internal` when the type, or any containing
type, is not public (was CS0060).
- **Matrix properties:**
- `MatrixOf<T>` properties use the inline matrix encoding.
- Matrices of non-sealed structures, or with
`StructureHandling.ExtensionObject`, are written as ExtensionObjects.
- Their published ValueRank is 2, because the rank can't be known from
`MatrixOf<T>`.
- **Published StructureDefinitions:**
- They include base-class fields.
- Nullable properties are no longer marked optional.
- Inline structure fields name their concrete type.
- **`[Flags]` enums:** they are published as plain enumerations with
their member values, which matches how they are encoded.
- **Other generated code:**
- `Clone` deep-copies arrays and matrices of structures, Variants,
ExtensionObjects and DataValues.
- `IsEqual` and `GetHashCode` are consistent: EncodingMask, active union
member and NaN handling agree.
- Pooled `Reuse()` restores the freshly constructed state through the
new `protected virtual ResetForReuse()`, and returns an instance to its
runtime type's pool.
- **Enum capture:** enum member values are captured culture-invariantly.
Negative values were lost on cultures that use U+2212 as the minus sign.
### Model-driven generator: generated code, API and file names
- **Removed API:** generated `*_Placeholder` proxy accessors (e.g.
`PowerTrainTypeClient.GetMotorIdentifier_PlaceholderAsync`) and fluent
`X_Placeholder()` accessors are removed; they could never resolve
anything.
- Proxy accessors now look children up by BrowseName with the right
namespace.
- `RoboticsClient` finds motors and gears by type and drives via
`IsDrivenBy`. Its topology snapshots used to be empty.
- **Renamed files:** generated files for a bound `[NodeManager]` are now
named `{Namespace}.{Class}.NodeManager.g.cs` (also `.Factory` and
`.FluentBuilders`).
- **Generated NodeState code:**
- Attributes are set through `baseState`/`nodeState` locals, so children
named like base attributes (e.g. `DataType`, `EventNotifier`) compile.
- Children that hide base members are declared `public new`, using names
reflected from the runtime.
- `global::` qualification is used throughout.
- **Proxies and fluent builders:** a proxy whose supertype is excluded
(e.g. Draft) derives from the nearest emitted ancestor. Fluent wrappers
and NodeState factories fall back the same way; they used to fail with
CS0246.
- **Derived structures:**
- The optional-field `EncodingMask` continues across inheritance.
- A derived structure over a base type from another model no longer
relies on `base.ResetForReuse`.
- **Default values:**
- NodeId, QualifiedName and ExpandedNodeId defaults resolve by namespace
URI (`context.NamespaceUris.GetIndexOrAppend`) and server URI.
- StatusCode, negative enum, `double`/`float` (shortest round-trip
literal) and escaped string defaults now compile.
- **Event records:**
- Vendor event records have `Decoder.GetStandardFields(NamespaceTable)`,
and their browse paths use the model's namespace.
- A field whose namespace is unknown to the session no longer matches a
namespace-0 field.
- Companion `StandardFields` is `[Obsolete]`.
- Vendor simple subtypes such as `Percent : Double` map to their
built-in type.
- **Other fixes:**
- `MethodState.CallAsync` passes the real `objectId` to synchronous
`OnCallMethod2` handlers; it used to pass `NodeId.Null`.
- Enumeration fields with an explicit `Identifier` keep it, instead of
taking a trailing `_<digits>`.
- Explicit NumericIds are no longer reused by automatic numbering.
- Dependencies are loaded in topological order.
### Generated address-space content
- **Arguments:**
- Methods without arguments no longer get empty
`InputArguments`/`OutputArguments` properties (OPC 10000-3 5.7).
- About 2,660 automatically assigned namespace-0 NodeIds of 15000 and
above shift. Every NodeId in `StandardTypes.csv` is unchanged.
- **Permissions:** type nodes and method declarations on types now carry
the model's `RolePermissions`/`AccessRestrictions`.
- **Restored nodes:** NodeSet import keeps nodes that were silently
dropped before:
- `NamespaceMetadata` objects and the NodeSet's own TypeDictionary
variables;
- ISA95 placeholders linked only non-hierarchically;
- instances whose parent is in another namespace.
- **Import details:**
- ValueRank > 1 without ArrayDimensions keeps its rank.
- `svr=` indexes map correctly.
- Invalid MinimumSamplingInterval values import as -1, not 0.
- Localized texts prefer the invariant or English translation.
- **StructureDefinitions:**
- They include inherited fields, including for subtypes without their
own fields (e.g. `AnonymousIdentityToken` now publishes PolicyId).
- The StructureType kind covers inherited AllowSubTypes fields.
- Unions ignore IsOptional.
- StructureFields never publish ValueRank 0; a OneOrMoreDimensions field
without dimensions becomes rank 2.
- Fields with ValueRank -2/-3 are published as scalar BaseDataType,
which is what is on the wire.
- **OptionSets:**
- Implicit fields get the next free bit.
- `OptionSetValues` uses null for undefined bits instead of "Reserved",
and structure OptionSets publish all their bits (no 32/96-bit cap).
- Numeric OptionSets are limited to their base type's width, and UInt64
bit 63 works.
- **Schemas:**
- Structures with inline-matrix fields are left out of the `.bsd`
(5.2.5).
- In the BSD, Variant-encoded and non-structure subtyped fields are
described as `ua:Variant`.
- In the `.xsd`, matrix fields are typed `ua:Matrix` with
`Dimensions`/`Elements`, and `EncodingMask` is required.
### NodeSet / model input handling
- **Model selection:**
- The newest NodeSet of a model is chosen by `ModelVersion` (SemVer 2.0
precedence), then PublicationDate. The `Version` attribute, which Annex
F says is not for comparison, is only a tie-break.
- The order is total and does not depend on input order; referenced
assemblies use the same rule.
- **Default names:**
- Invalid default Name/Prefix values are repaired (`201301ISA95` becomes
`_201301ISA95`, `class` becomes `class_`).
- Valid names are unchanged.
- Sanitising no longer depends on the OS.
- **`ModelUri` metadata** that doesn't match the NodeSet raises a
warning instead of silently losing the model.
- **Input detection:**
- Only XML files whose root is `ModelDesign` or `UANodeSet` are treated
as models.
- A malformed NodeSet stays a NodeSet input, so it no longer breaks the
ModelDesign pass.
- **`IdentifierFile` paths:** they are normalized (`./`, `../`), and the
suffix match requires a folder boundary.
- **Dependency payloads** (`ModelDependencyV1`) carry field IsOptional,
AllowSubTypes, ArrayDimensions and the producer's namespace tables in
skippable trailers, so old and new readers stay compatible.
### Roslyn host, diagnostics, packaging
- **New diagnostics:**
- MODELGEN036: `[NodeManager]` target not supported (nested, generic,
file-local or global namespace).
- MODELGEN037: `[DataType]` target not supported (struct, generic,
abstract, file-local or global namespace).
- MODELGEN038: the definition of an encodeable base type can't be found.
- **New validator errors:**
- a structure with both optional and subtyped fields (OPC 10000-6 F.13);
- multi-bit or duplicate OptionSet masks.
- **Diagnostic locations:** `[DataType]`/`[NodeManager]` diagnostics
point at real source locations again, so `#pragma` and `.editorconfig`
apply. MODELGEN010 is the exception.
- **Incremental caching:** pipeline values compare by value, so
unrelated edits no longer regenerate the whole model or all
`[DataType]`s.
- **`ModelSourceGeneratorIgnore`** on a ModelDesign input is honoured;
the design still resolves as a dependency.
- **Cancellation:** a cancelled generation run propagates
`OperationCanceledException` instead of reporting a MODELGEN003 error.
- **Stack package:** the `Stack` NuGet package now ships
`build/OPCFoundation.NetStandard.Opc.Ua.SourceGeneration.Stack.props`,
so `StackSourceGeneratorMode` and `StackSourceGeneratorExclude` reach
the compiler.
## Related Issues

Add a documentation learning path and fix issues found while verifying it (#4555)
## Summary
### Documentation
- Stage the documentation index as a learning path: a first application,
independent client, server, and PubSub paths, then data and services,
companion models, production, advanced integration, and draft or
experimental capabilities.
- Add Getting started (repository samples or NuGet packages), OPC UA
concepts, Your first information model, and a production readiness
checklist.
- Add Native AOT application publishing, a first PubSub publisher and
subscriber exchange, and the UDP transport options.
- Add or expand contents navigation throughout `docs/`, and keep
contributor documentation separate.
- Correct outdated SDK examples and capability guidance, consolidate
repeated explanations into canonical guides, and repair local links and
heading structure.
- Rewrite What's New in 2.0 as a concise feature overview with short
linked details; keep migration instructions in the Migration Guide.
- Expand the feature catalogue with specification IDs, GDS, LDS, the OPC
10000-21 onboarding registrar, ISA-95, xRegistry, OpenUSD, and
sample-local models; distinguish draft status, explain crypto
pluggability, and bring performance guidance forward.
- Address review feedback on wording, active monitored items during
shadow reload, and the `Samples.md` filename and references.
- Regenerate the `opcua-v20-migration` plugin's bundled copy of the
migration guides so it matches the edited `docs/migrate/2.0.x` guides.
- Merge the latest `master`, preserving upstream resource-isolation
guidance within the task-based documentation index.
- Retain deferred Lingity findings where appropriate; this PR does not
claim that every document meets the Lingity score thresholds.
### Fixes found while verifying the guides
Each fix has regression tests that fail without it.
- **Client:** V2 subscriptions compared their lifetime with the
operation timeout instead of the session timeout, and logged a spurious
warning. `ISubscriptionEngineContext`, which is new in 2.0, gains a
`SessionTimeout` property; implementations must add it.
- **PubSub:** a subscriber now registers the `DataSetMetaData`
configured on its readers (OPC 10000-14 6.2.9.4), and the UADP decoder
decodes DataSetMessages that carry no ConfigurationVersion. Before, a
secured subscriber of the reference sample received no DataSets.
- **Source generator:** a ModelDesign method that declares its arguments
inline, without a method type, produced code that did not compile; it
now uses `MethodState`. The generated code of existing models is
unchanged.
- **MinimalClient sample:** waits for its first data-change notification
before it disconnects.
### Known issues, not addressed here
- UDP multicast: the publisher does not send on the interface that the
subscriber joins, and `MulticastLoopback` defaults to false. The PubSub
guide uses unicast for the exchange on one computer.
- The UDP metadata announcement is sent unsecured on secured writer
groups; a secured subscriber drops it with a warning.
- A server does not start in globalization-invariant mode, because
`ResourceManager` creates `CultureInfo("en-US")`. The Native AOT guide
cautions against the mode.
## Validation
- `git diff --check` and
`./.azurepipelines/validate-migration-plugin.ps1` (15 bundled migration
docs validated, plugin manifests synchronized).
- Local Markdown links, anchors, file-link casing, and contents lists
checked across all 87 documents under `docs/`. The index links every
top-level guide and every target of the previous index.
- Both Getting started routes, Your first information model, the PubSub
exchange, and the Native AOT publish of the Getting started client and
server were run as documented. The NuGet route and the tutorial use the
public `2.0.0-preview.5` packages.
- The changed libraries build for all target frameworks in Release
without warnings.
- Tests on .NET 10: Opc.Ua.SourceGeneration.Tests 199 passed;
Opc.Ua.SourceGeneration.Core.Tests 3,977 passed, 8 skipped;
Opc.Ua.Server.Tests `Fluent` category 621 passed; Opc.Ua.Client.Tests
subscription-engine tests 70 passed; Opc.Ua.PubSub.Tests 1,374 passed, 2
skipped; PubSub fuzz replay 145 passed. The new and affected tests also
pass on .NET Framework 4.8.
- Earlier merge validation: 174 resource-isolation tests passed on .NET
10.
- The full solution suite was not run locally.
Review and validation artifacts are maintained outside the repository.

Run the fluent configure pipeline in FluentNodeManagerBase (#4537) (#4538)
## Proposed changes Closes #4537. The configure pipeline now lives in `FluentNodeManagerBase`, so a hand-written fluent node manager only overrides `ConfigureAsync` and no longer writes `CreateAddressSpaceAsync` itself. `FluentNodeManagerBase.CreateAddressSpaceAsync` now: 1. loads the predefined nodes (as `AsyncCustomNodeManager` did before), 2. creates a builder for `NamespaceIndex` with `CreateFluentBuilder`, 3. awaits `ConfigureAsync(builder, ct)`, 4. runs `RegisterAuthoredNodesAsync` and then `CompleteConfigureAsync`, 5. finishes with `SealConfigurationAsync`, which seals the builder, replays `NotifyNodeAdded`, then activates behaviors and simulations. ### Breaking change (2.0) Some managers need a different order, for example a post-setup runner before sealing, a builder for another namespace, or work after sealing. They must stop calling `base.CreateAddressSpaceAsync`, because that would now run a second, empty pipeline and seal the manager-owned registries too early. These managers now call `LoadPredefinedNodesAsync(SystemContext, externalReferences, ct)` and keep driving their own pipeline: - the source-generated `NodeManager` template (the ordering test in `NodeManagerGeneratorTests` is updated) - `DiNodeManager`, `Isa95NodeManager`, `PositioningNodeManager`, `RobotIntentNodeManager`, `VisionNodeManager` - `samples/OpenUsd/SiteCompositionServer/SiteNodeManager` These now use the base pipeline: - `samples/FluentApi/BasicFluentApiServer/BasicFluentNodeManager` becomes a single `ConfigureAsync` override. Before this change it never sealed its builder. - the hosting `FluentNodeManager` (from `AddNodeManager(namespaceUri, build)`) becomes a `ConfigureAsync` override. It now seals through `SealConfigurationAsync`, so `OnNodeAdded` handlers wired in the build delegate fire. Before, it called `builder.SealAsync()` directly and they did not. Docs (`NodeManagers.md`, `DeviceIntegration.md`) are updated. `NodeManagers.md` gets a short hand-written `ConfigureAsync` example. ## Types of changes - [x] Breaking change (fix or feature that would cause existing functionality to change) - [x] Enhancement (non-breaking change which adds functionality) ## Checklist - [x] I have read the CONTRIBUTING doc. - [x] I have signed the CLA. - [x] I ran tests locally with my changes, all passed. - [x] I fixed all failing tests in the CI pipelines. - [x] I fixed all introduced issues with CodeQL and LGTM. - [x] I have added tests that prove my fix is effective or that my feature works. - [x] I have added necessary documentation (if appropriate). ## Tests New `FluentNodeManagerBasePipelineTests`: nodes authored in `ConfigureAsync` get registered, the Objects-folder reference is mirrored into `externalReferences`, `OnNodeAdded` fires once, and the builder is sealed afterwards. Local run on net10.0, all passing: - Opc.Ua.Server.Tests (Fluent/Hosting/StateMachine/RuntimeNodeSet filter): 1286 - Opc.Ua.SourceGeneration.Core.Tests (NodeManager filter): 40 - Opc.Ua.Di.Tests 426, ISA95 136, Positioning 69, Robotics 636, Robotics.Intent 22, Vision 484 (+1 skipped), Vision.Intent 14, OpenUsd 921 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com> |

Fix AI model version and inference argument handling (#4512)
## Summary
- Derive the AI server''s advertised specification version from
generated NodeSet metadata (new source-generated `ModelVersions.Target`
constant), so `AINodeManager.SpecificationVersion` can no longer drift
from the shipped model.
- Preserve inference parameters through inline, asynchronous, fallback,
and oversized-transfer execution instead of silently discarding them.
- Reject unsupported `PayloadUri` input explicitly with
`BadNotSupported` before any backend call, job creation, or transfer
allocation.
- Apply the supported `temperature` / `max_tokens` / `top_p` parameters
in both built-in backends via a shared parser.

Support guid/opaque nodeids in NodeSet import (#4507)
# Description
`NodeSetToModelDesign.ImportNode` only stored Numeric and String NodeId
identifiers. Guid and Opaque identifiers (both valid per OPC 10000-3
5.2.2) fell through to an `Information` log line, so the node was
registered in `NodesByQName`/`NodesById` with no identifier at all and
code generation continued against a node whose identity had been
discarded.
The `ModelDesign` schema has no representation for Guid/Opaque
identifiers (`NodeDesign` exposes only `NumericId`/`StringId`), so the
import now fails loudly instead of emitting output that looks correct.
- **Importer**: the fall-through branches in `ImportNode` are replaced
with an `InvalidDataException` naming the NodeId, browse name and
identifier type. This matches the existing unsupported-input handling in
the file and surfaces through `ModelCompilation` as a generator
diagnostic.
- **Logger removal**: `m_logger` had no remaining use in
`NodeSetToModelDesign` and was removed along with its
`Microsoft.Extensions.Logging` import.
- **Tests**: `ImportUnsupportedNodeIdTypeThrowsInvalidDataException`
covers Guid, empty Guid and Opaque identifiers via an in-memory NodeSet.
- **Docs**: the source generator readme states the NodeSet2 identifier
restriction.
```csharp
else
{
// The model design can only carry numeric and string identifiers.
// Guid and Opaque identifiers (OPC 10000-3 5.2.2) would be dropped
// and code would be generated for a node without any identity, so
// the import fails instead of silently producing wrong output.
throw new InvalidDataException(
$"NodeId ({input.NodeId}) of node '{input.BrowseName}' uses the " +
$"{nodeId.IdType} identifier type which is not supported by the model " +
"design. Only Numeric and String identifiers can be imported.");
}
```
Note on behaviour: a null/unspecified NodeId parses as a Numeric
identifier (`i=0`) and is still handled by the numeric branch, so the
removed `IsNull` branch was only ever reachable for an empty Guid or
Opaque identifier, which is now reported as unsupported.

Preserve non-child hierarchical references during NodeSet import (#4491)
# Description Preserve forward and inverse same-namespace hierarchical references that are not already represented by the NodeSet importer's parent/child relationship. A reference is implicit only when both its endpoints and its exact reference type match the selected ownership relationship; additional links do not reparent their targets. Also fix the generated-reference duplication that blocked the previous attempt in #4473. Inherited and declared `NodeDesign` objects can differ structurally while resolving to the same runtime reference. Deduplicating by the emitted reference-type ID, direction, and target ID prevents identical `AddReference` calls from throwing during Robotics/OpenUSD startup. - Add 21 importer/generator regression cases, including a minimized recursive-placeholder reproduction of the startup failure. - Strengthen the reference-server test to check the original missing forward links, inverse counterparts, subtype filtering, and unchanged ownership. - Document ownership versus graph references in `docs/NodeManagers.md`. ## Validation Confirmed the missing-reference cases fail before the importer fix, and the minimized duplicate-reference case fails before the generator fix. The original Robotics/OpenUSD fixture passed before the changes, failed with the importer-only candidate, and passes with both fixes. | Suite | net10.0 | net48 | | --- | --- | --- | | SourceGeneration.Core.Tests | 3,961 passed; 8 existing skips | 3,961 passed; 8 existing skips | | SourceGeneration.Stack.Tests | 94 passed | 91 passed | | SourceGeneration.Tests | 185 passed | 185 passed | | Di.Tests, including all 17 RobotOpenUsdE2eTests | 425 passed | 425 passed | | ReferenceServerTests | 45 passed | 45 passed | Executed using `CustomTestTarget` with `dotnet test tools/SourceGeneration.slnx`, the Di test project, and the `ReferenceServerTests` filter in the Server test project.

Fix source generator defects from the Client/Types/SourceGeneration audit (#4473)
# Description
Fixes the SourceGeneration findings of a read-only bug audit of
`a05a36055` — sections 15 (host generators, Roslyn side), 16
(SourceGeneration.Core schema / ModelDesign loader) and 17
(SourceGeneration.Core generators). 36 of the 39 findings are fixed;
each has a regression test.
### Generated-code correctness
- **State machine NodeId constants** were emitted as `const uint` even
when the aliased `Objects` constant is a `string`, so every model using
string NodeIds with a `FiniteStateMachineType` subtype failed with
CS0029. The constant type now follows the aliased node, looked up from
the same source `NodeIdGenerator` emits from — top-level nodes **plus
each node's instance hierarchy**, since a state or transition only ever
exists as a hierarchy entry.
- `NodeIdGenerator` emitted string identifiers into C# string literals
without escaping them.
- Structure field names are authored data, so they can be C# keywords or
collide with the members every generated data type carries. Properties
and `{Type}Fields` members now go through a sanitizing,
collision-breaking mapping (including two siblings that sanitize to the
same identifier). **Wire names are untouched** — OPC 10000-3 §8.51
requires the StructureField name to match the BrowseName, and the
`DataMember`/encode/decode names still come from `Parameter.Name`.
- `NodeStateGenerator`'s copy-on-write cast now uses the fully qualified
data type name, which a cross-model structure needs.
- `GetScalarValueAsCode` emitted `(double)NaN` and the infinities, which
do not compile.
- `TemplateWriter` formatted with the current culture, so a machine with
a comma decimal separator emitted invalid generated source.
### Served schema documents
- The binary schema described a **different wire layout than the
generated `Encode`/`Decode`**: unions carried no
`SwitchField`/`SwitchValue`, and structures with optional fields carried
no encoding-mask presence bits. Both are now emitted per **OPC 10000-6
§5.2.7**, matching the layout the runtime `BsdSchemaGenerator` produces.
A structure with more than 32 optional fields now fails generation
instead of silently wrapping `1 << 32` back onto the first field's bit.
- Documentation text and attribute values are XML-escaped.
### ModelDesign loading and validation
- Identifiers pinned in a CSV were dropped whenever any other loaded
namespace declared the same symbolic name. Removal is now scoped to the
file's target namespace, and explicit `NumericId`s are keyed by
`(namespace, id)` so the same number in two namespaces is legal.
- Declaration order inside a design file no longer matters — base types
are imported and validated ahead of their subtypes.
- OptionSet `OptionSetValues` were truncated at bit 31 (signed shift)
and bits 32–63 of a 64-bit option set were never emitted.
- An authored `ValueRank` is no longer overwritten by the shape of the
default value (OPC 10000-3 §6.2.8: a ValueRank may only be further
restricted), and a VariableType data type may be narrowed any number of
levels deep rather than exactly one.
- NodeSet import: `AccessRestrictions="0"` means "no restrictions", not
`EncryptionRequired` (OPC 10000-3 §8.56) — an unrecognised mask stays
**fail-closed**; a NodeSet without `<Models>` reports what is wrong; an
optional `<References>` no longer throws; the parent/child reference
scan looks at the parent's references; and `IsTypeOf` terminates on the
self-referential root reference types NodeSets routinely declare.
- Version comparison is numeric per component (ordinally `"1.05.9"`
sorts above `"1.05.10"`) and now lives on `SemVer`, so the NodeSet
collection and the dependency tie-break cannot pick different winners; a
publication-date version no longer outranks a real one.
### Host generator
- `[DataType]` on an `enum` is matched again (an enum is not a
`TypeDeclarationSyntax`), MODELGEN003 renders its arguments instead of
the raw template, and the Types hint name keeps the namespace's dots so
`A.BC` and `AB.C` cannot claim the same one.
- Compilation-derived pipeline stages carry value comparers, so editing
a file no longer re-runs the entire model generation on every keystroke.
- A NodeSet that fails to load skips that file rather than every
remaining one; a file listed twice as an `AdditionalFile` is deduped;
superseded NodeSet versions are still recognised as NodeSet inputs and
not generated a second time by the ModelDesign pass.
- `LogLevel.Critical` maps to a diagnostic instead of being silently
dropped.
### Client
- `EventRecordFieldReaders` gained the readers the event record
generator needs (including `Variant`, enumerations and the array forms).
Fields whose type had no reader were declared on the record but never
populated, so they read as `null`/`default` for every event.
## Not fixed (deliberately)
- **Forward same-namespace hierarchical references in
`NodeSetToModelDesign.ImportReferences`** — the audit flags the
inverse-only handling as asymmetric. Making it symmetric compiles and
passes every generator unit test, but regresses the address space: all
17 `RobotOpenUsdE2eTests` fail in `OneTimeSetUpAsync` because the hosted
server never finishes starting. Reverted, with a comment at the site
recording why.
- **§17.10 and §15.10** (both low + PLAUSIBLE) — each needs a wider
refactor than this PR: a consistent NodeId-constant rename across ~6
cross-reference sites, and replacing `Location` with a serializable
equivalent for incremental cache equality.
## Spec cross-check
The encoding/schema changes were checked against the specification: OPC
10000-6 §5.2.7 (32-bit EncodingMask, one bit per optional field in
order, padded), the union `SwitchField` encoding, OPC 10000-3 §8.56
(AccessRestrictionType bit mask), §6.2.8 and §5.6.2/§5.6.5 (ValueRank),
§8.51 (StructureField name == BrowseName).
`GenerateStackTests.OptionalFieldBitsAgreeBetweenBsdAndGeneratedEncoder`
pins the BSD presence-bit order against the generated encoder's
`LogRecordFields` so the two cannot drift apart again.

Reimplement the GDS ApplicationsNodeManager as a generated fluent node manager (#4434)
# Description Builds on #4428, which is now merged; this branch is rebased onto master. The GDS `ApplicationsNodeManager` becomes a source-generated `[NodeManager]`: the companion model, its loader and the fluent plumbing are emitted, and what stays hand-written is the behaviour. Getting there needed three things from the shared surface, which are the first two commits. ## Commits **1. Add the fluent hooks a hand-written manager needs at startup** - `OnReadRolePermissions` / `OnReadUserRolePermissions` on the node builder. Every other `NodeState` `On*` hook was already fluent; these were not, and a server that grants access on something the static model cannot express has to compute the permission set per request. - `Node<TState>(TState)` returns a builder over a node the caller already holds, for nodes materialised after `Configure` resolved its graph. - `OnAddressSpaceReadyAsync` on `FluentNodeManagerBase` — the one seam between the address space existing and the wiring being applied, for managers whose wiring depends on asynchronous setup. `Configure` is a `partial void` and cannot await. `DiNodeManager` had already invented the hook privately, so its declaration becomes an `override`. **2. Let a `[NodeManager]` bind to a model a referenced assembly supplies** A model belongs to the assembly that emits its types, which leaves a node manager for it homeless whenever that assembly cannot reference `Opc.Ua.Server` — a model-only package shared with clients, for instance. Binding was rejected twice over: the design was skipped before the binding was matched (`MODELGEN010`), and fluent-accessors-only mode refused to run alongside manager generation (`MODELGEN014`). The binding is now matched before the skip decision, and a matched binding puts that design into accessors-only mode. A design nothing binds to is still skipped, so this cannot start duplicating types by accident. The emitted manager also gains what a real manager needs: `DefaultNamespaceUris()` plus a protected constructor taking a replacement set; `GenerateDefaultConstructor=false` to suppress the two-argument form; its own logger category; and the call to `OnAddressSpaceReadyAsync`. Generated fluent accessors also stop re-enabling nullable warnings — a bare `#nullable enable` undid the shared header's `disable warnings`, so any model with a structure-typed method argument reported CS8600 on every generated `out T` in a project that builds warnings as errors. **3. Reimplement the GDS `ApplicationsNodeManager` as a generated node manager** The design stays owned by `Opc.Ua.Gds.Common`; the server assembly only binds a manager to it. **NodeIds do not move.** `NamespaceIndexes[0]` must stay the application record namespace — it is the one the application database, the certificate request store and the base allocator mint ids in — so the constructor passes the namespace order explicitly rather than adopting the generated model-first default. A test pins both ends against a live server. Four overrides go, leaving `OnAddressSpaceReadyAsync` and `Dispose(bool)` — no address-space overrides at all: | Removed | Why it was unnecessary | | --- | --- | | `New` | The base allocator already mints into `NamespaceIndexes[0]`, with a thread-safe counter. The override existed only because `Create(assignNodeIds: true)` asks the factory with the declaration id still set; `AssignInstanceNodeId` nulls it and re-asks, documented as being there for exactly this allocator. | | `AddBehaviourToPredefinedNodeAsync` | Its `AuthorizationServiceType` branch re-wired a node that was already wired, and its `KeyCredentialServiceType` branch had nothing to wire — the model ships that folder empty. | | `GetManagerHandleAsync`, `ValidateNodeAsync` | Verbatim reimplementations of the base that also blocked the fluent base's virtual-node support. | | `DeleteAddressSpaceAsync` | A `// TBD` passthrough. | Everything else — all sixteen directory methods with their self-administration permissions, the certificate groups' concrete types and trust-list flags, and the authorization service (created through this PR's `Add` surface and wired in the same place) — is one `Configure` pass. **4. Bind the certificate groups from the `Configure` pass** Acquiring a certificate group and binding it to its nodes are different kinds of work: the first is I/O (`InitAsync` opens certificate stores and creates CA certificates), the second only touches the address space. Each now runs in the phase it belongs to, which puts the whole of the wiring in one place. Ownership no longer rides on the binding. A group joins `m_ownedCertificateGroups` the moment it is constructed, before `InitAsync` can throw, so a group that fails half way through is still disposed — which the previous code could not manage, keying ownership off a dictionary it filled only after initialization succeeded. > Commit 3's message says this move is impossible and blames `PushTest`. **That was a wrong diagnosis, and this commit supersedes it.** Two real defects were hiding behind those failures: - **`Create(..., NodeId.Null, ..., assignNodeIds: false)` does not null the NodeId.** `NodeState.Create` overrides it only when handed a non-null one, so a custom group node kept the namespace-0 id of its type declaration. `AssignInstanceNodeId` hid this by re-asking the factory with the id nulled; the builder validates instead, and rejected it. The node is now created with an id in the manager's own namespace, as the `Default` authorization service already was. - **The custom certificate group node was not browseable.** It answered `GetCertificateGroups` and `ReadNode`, but a type-filtered recursive browse from the Objects folder never returned it — which OPC 10000-12 §7.8.2 requires of a certificate group. Staging the node through the builder gives it the reference it was missing. ### Two `PushTest` methods change — please review these closely The second defect had been masking what those tests actually did. Selecting the group positionally, `groups[3]` resolved to the server's **own `ServerConfiguration` group** while the custom one stayed invisible, so `UpdateTrustListOfCustomGroupAsync` and `AddRemoveCertOfCustomGroupAsync` were exercising a *transactional* trust list under a custom-group name. Browse results, before and after: | # | Before (baseline) | After | | --- | --- | --- | | 0-2 | GDS Directory groups (`ns=3`) | GDS Directory groups (`ns=3`) | | 3 | **`DefaultApplicationGroup` `i=14156`** — the server's own | **`MyCustomGroup` `ns=2`** | | 4 | — | `DefaultApplicationGroup` `i=14156` | They now resolve the group by browse name — which asserts it is browseable at all — and expect the immediate-apply semantics the GDS actually gives the groups of its own `Directory`: `CloseAndUpdate` writes the stores at once and reports `applyChangesRequired == false`, so the `ApplyChanges` calls go away (they would return `Bad_NothingToDo`). The read-back assertions are what prove the writes landed, and they are unchanged. This is a genuine loss of the *transactional* trust-list coverage those two methods were accidentally providing — the server's own group is still covered by the other `PushTest` methods, which target it deliberately. **5. Select `GetCertificates` results by type instead of by position** `GetCertificatesAsync` checked entry zero of a parallel-array result. Which entry that is depends on the order the server reports its certificate types in, an empty result throws `IndexOutOfRange` rather than failing an assertion, and a second type going missing or unparseable would not be noticed. Every returned pair is now checked, and a failure names the certificate type. **6. Drop the `.Common` suffix from the three GDS projects** Every other companion specification ships as `<Family>` / `<Family>.Client` / `<Family>.Server` — Di, ISA95, Positioning, Robotics, Vision, WotCon, XRegistry. GDS was the exception, with a `.Common` suffix that named nothing. | Before | After | | --- | --- | | `src/Opc.Ua.Gds.Common` | `src/Opc.Ua.Gds` | | `src/Opc.Ua.Gds.Client.Common` | `src/Opc.Ua.Gds.Client` | | `src/Opc.Ua.Gds.Server.Common` | `src/Opc.Ua.Gds.Server` | **No source changes were needed.** `RootNamespace` was already the final name in all three projects — the namespaces have always been `Opc.Ua.Gds`, `Opc.Ua.Gds.Client` and `Opc.Ua.Gds.Server`, and only the assembly and package ids disagreed. Nothing compiling against these assemblies changes a `using`. The package ids do change, which is consumer-visible, so `docs/migrate/2.0.x/packages.md` gains a renamed-packages section — it is the document that undertakes to cover NuGet renames — and the migration skill's package table gains the two rows a 1.5.378 consumer needs. Build infrastructure that names the projects or their output moves with them: both solution files, `expected-packages.txt` (re-sorted — it is maintained alphabetically), both signing manifests, the reference-server Dockerfile, the metapackage nuspecs, and the analyzer's package dependencies. `preview-pack.slnx` is derived from `UA.slnx` and needs no edit. The migration analyzer's shim tree mirrors the source layout by its own documented convention, so `Gds.Client.Common/` becomes `Gds.Client/`. Prose naming past work is left alone — plan 23 still records that its deferral happened during the "GDS Client.Common modernization", which is the name that effort had. ## Validation `net10.0`, on master + these four commits, from a clean GDS PKI: - `UA.slnx`: 0 errors, 0 warnings in changed files (the solution's 30 pre-existing warning lines are CA1861/CA1850/CA1307 in `XRegistry`, `Types.Tests` and `WotCon.Tests` — same rules and projects as the base). - `Opc.Ua.Gds.Tests`: 1,117 passed, 0 failed, 54 skipped — identical to the base branch. - `Opc.Ua.Server.Tests`: 4,961 passed, 0 failed, 5 skipped (measured before commit 4, which touches only the GDS assembly and its tests). - `Opc.Ua.SourceGeneration.Tests`: 169 passed. - `Opc.Ua.SourceGeneration.Core.Tests`, NodeManager/Generators/Fluent: 84 passed; `GenerateCode`: 21 passed, 4 skipped. - `Opc.Ua.MigrationAnalyzer.Core.Tests`: 10 passed, 3 skipped. - After the rename: assemblies build as `Opc.Ua.Gds.dll` / `.Client.dll` / `.Server.dll`, with no `*.Common.dll` produced anywhere. - Commits 1-3 build standalone. - `Opc.Ua.Gds.Server.Common` also builds for `net48` and `netstandard2.1` (checked before the rebase onto #4428). Not yet run: the full `Opc.Ua.SourceGeneration.Core.Tests` suite (~3,800), and the older target frameworks since the rebase. ## Checklist - [x] Existing tests pass - [x] New tests cover the new surface (role permissions, resolved-node builder, referenced-model binding, constructor/namespace control, GDS namespace invariant, custom-group node namespace) - [ ] Full Core.Tests sweep and net48/netstandard2.1 re-run after the rebase 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Opus 5 <noreply@anthropic.com> Co-authored-by: Copilot Autofix powered by AI <175728472+Copilot@users.noreply.github.com> |

Make the fluent node manager's configure/seal path genuinely async (#4442)
# Description The fluent node-manager pipeline had two synchronous chokepoints, and two independent efforts have now hit both of them. `Configure` is a `partial void`, so it cannot `await`. A manager whose wiring depends on asynchronous setup had to invent a second hook outside the pipeline, create its own builder there, and hand-roll `CreateFluentBuilder(...).Configure(...).Seal()` inside it. `Seal()` was synchronous, so nothing a registration staged during `Configure` could be completed by awaiting. Registrations that needed to await either blocked — `EventSourceRegistry` did `.GetAwaiter().GetResult()` on the manager's root-notifier registration — or could not be expressed at all. ## What changed **`FluentNodeManagerBase.ConfigureAsync(INodeManagerBuilder, CancellationToken)`** is the awaitable wiring seam. It runs once per activation, with the manager's attached builder, immediately *before* the synchronous `Configure` partial(s) — so instances it materialises are in the address space by the time `Configure` wires callbacks against them. The default implementation is a no-op. It is a `virtual` method rather than a second `partial` declaration because a partial method can be optional (`partial void`, no return value) or awaitable (an extended partial method, which must be implemented) — not both, and the generator would otherwise have to detect which one the user declared. `partial void Configure(INodeManagerBuilder)` keeps working unchanged; a manager uses either hook or both. **`NodeManagerBuilder.Seal()` becomes `SealAsync(CancellationToken)`.** Sealing is now the single point where registrations that could not finish inside `Configure` get their turn to await. Every seal site awaits it, so a later change can move registry *setup* onto the same seam. **`DiNodeManager` now runs the standard pipeline itself** — create and attach the builder, `await ConfigureAsync`, `RegisterAuthoredNodesAsync`, `CompleteConfigureAsync`, the post-setup runner, then `await builder.SealAsync` — instead of handing subclasses a bare callback and leaving them to build and seal on their own. DI subclasses gain node registration and the reverse-reference pass, which they previously skipped. Sealing deliberately comes **after** the post-setup runner. The fluent registries are owned by the manager, not by a single builder, and sealing starts them — so sealing first locks post-setup configurators out of registering simulation loops of their own, which is exactly what `AddRobotics`' configurators do. Sealing before the runner makes `MinimalRobotServer` fail to start with *"Cannot add a simulation loop after the registry has started"*. Worth knowing for follow-up work: with several builders attached to one manager, the first seal freezes the shared registry for all of them. ## Workarounds removed - **`DiNodeManager.OnAddressSpaceReadyAsync`** — deleted. Its three overriders (`RoboticsNodeManager`, and the `PumpNodeManager` / `GeneratorNodeManager` samples) now override `ConfigureAsync` and no longer hand-roll `CreateFluentBuilder(...).Configure(Configure).Seal()`. - **`EventSourceRegistry`'s `.GetAwaiter().GetResult()`** on `AddRootNotifierAsync` — gone. `Publish(..., RegisterAsRootNotifier: true)` now stages the registration and `SealAsync` drains it, so the wait happens on an awaited path. A source whose root-notifier registration fails is rolled out of the registry before the failure surfaces, and a registry disposed before its builder sealed drops what it staged. - **`Isa95NodeManager.ConfigureStatusEvents()`** — the synchronous second builder pass is now `ConfigureStatusEventsAsync(CancellationToken)`, awaited from `CreateAddressSpaceAsync`. (`ConfigureCatalogChanges()` stays synchronous: it starts a background task and never seals a builder, so there was nothing to convert.) - **`IRoboticsBuildContext.Seal()`** — now `SealAsync(CancellationToken)`. These really were `NodeManagerBuilder.Seal()` calls behind a same-named method. The state transition still happens under the context lock; the builder's asynchronous completion runs outside it, so no `await` is taken while the lock is held. - The Pump / Generator incremental registration callbacks (`onRegistered`) changed from `Action<T>` to `Func<T, CancellationToken, ValueTask>` so their per-instance builder pass can await its own seal. No sync-over-async was introduced anywhere. `Dispose(bool)` is unchanged and stays non-blocking; teardown remains in `DeleteAddressSpaceAsync`. `NodeManagerBuilder.Seal()` and `IRoboticsBuildContext.Seal()` are removed rather than kept as synchronous overloads. A synchronous seal that silently skipped the asynchronous completion would reintroduce exactly the failure mode this change exists to remove. ## Generator `NodeManagerTemplates` emits, in order: predefined nodes load → `await ConfigureAsync(__m_builder, cancellationToken)` → `Configure(__m_builder)` and the typed `Configure` → `RegisterAuthoredNodesAsync` → `CompleteConfigureAsync` → `await SealConfigurationAsync(__m_builder, cancellationToken)`. `NodeManagerGeneratorTests` asserts that order literally, and that neither `__m_builder.Seal()` nor the synchronous `SealConfiguration(__m_builder)` is emitted. ### Merging with #4432 #4432 landed on `master` while this was in review and reworked the same seam from the other side: it split `Seal()` into `SealGraphAuthoring()` + `StartSimulations()` so a manager can replay `NotifyNodeAdded` *between* the two halves — sealing first stops a lifecycle handler authoring nodes nothing would register, starting the simulations last stops a simulated value change preceding its own node''s `OnNodeAdded` — and added `FluentNodeManagerBase.SealConfiguration(builder)` as the one call the generator emits. Both intents are kept. That split is precisely why the asynchronous completion could not simply live inside `SealAsync`: a manager reaching the seam through the split path would silently skip it, which is the failure mode this PR exists to remove. So the asynchronous half became its own step: - `NodeManagerBuilder.CompleteSealAsync(ct)` drains the staged root-notifier registrations, then starts the simulations. `SealAsync(ct)` is `SealGraphAuthoring()` followed by it. - #4432''s synchronous `StartSimulations()` is gone, folded into `CompleteSealAsync`. It had exactly one production caller after the merge, and leaving it standing would have kept a second, synchronous way to activate a builder that skips the staged registrations — the very hazard this PR removes. Activation is now one step with one entry point; the *split* itself stays, because the replay has to sit between the halves. - `SealConfiguration` becomes `SealConfigurationAsync(builder, ct)`: seal the graph, replay `NotifyNodeAdded`, then `CompleteSealAsync`. Activation still happens last, so #4432''s ordering guarantee holds unchanged. ## Consumers unblocked - **#4434 ("Reimplement the GDS ApplicationsNodeManager as a generated fluent node manager")** adds `OnAddressSpaceReadyAsync` to `FluentNodeManagerBase` purely because, in its own words, *"`Configure` is a `partial void` and cannot await"*. That hook is unnecessary once `ConfigureAsync` exists — the GDS manager overrides `ConfigureAsync` instead, and the ordering it wants (predefined nodes → async setup → `Configure`) is what the generator now emits. #4434 has not merged yet, so it can drop its addition rather than have it simplified afterwards. - **Branch `romanett/fluent-node-behaviors`** moved `SimulationRegistry`, `EventSourceRegistry`, `MonitoredSourceRegistry` and the alarm wiring onto `AttachToType`/`Attach` for *release* only, because activation ran from `CompleteConfigureAsync` and most managers only called the synchronous `Seal()`. Every seal site now reaches `SealAsync`, so registry and alarm *setup* can move onto behavior activation too — the remaining half of that work. ## Tests - New `DiNodeManagerConfigureAsyncTests` drives the real `DiNodeManager.CreateAddressSpaceAsync` and asserts the hook runs once with an attached builder, that nodes it stages are registered, that their references to externally owned nodes are published, and that the builder is sealed before `CreateAddressSpaceAsync` returns. - `PublishTests` now pins the root-notifier deferral contract: registration is staged during `Configure`, lands only on the seal, and draining twice does not double-register. - Every `Seal()` call site in the test suites became `await ...SealAsync()`, including the three #4432 added in `NodeSetImportBuilderTests` and `SimulationBuilderExtensionsTests`. ## Related Issues No tracking issue was opened for this; it is the shared prerequisite extracted from #4434 and branch `romanett/fluent-node-behaviors`, both of which had independently worked around the same synchrony. Happy to open one if maintainers want the ADR trail. ## Checklist - [x] I have signed the [CLA](https://opcfoundation.org/license/cla/ContributorLicenseAgreementv1.0.pdf) and read the [CONTRIBUTING](https://github.com/OPCFoundation/UA-.NETStandard/blob/master/CONTRIBUTING.md) doc. - [x] I have added tests that prove my fix is effective or that my feature works and increased code coverage. - [x] I have added all necessary documentation. - [x] I have verified that my changes do not introduce (new) build or analyzer warnings. - [ ] I ran **all** tests locally using the **UA.slnx** solution against at least .net **framework** and .net **10**, and all passed. - [ ] I fixed **all** failing and flaky tests in the CI pipelines and **all** CodeQL warnings. - [ ] I have addressed **all** PR feedback received. ### What was actually run locally `UA.slnx` builds clean. Post-merge on **net10.0**: `Opc.Ua.Server.Tests` 5020/0 and `Opc.Ua.SourceGeneration.Core.Tests` 3813/0. Pre-merge the same run plus `Opc.Ua.Di.Tests` 425/0, `Opc.Ua.Robotics.Tests` 627/0, `Opc.Ua.ISA95.Tests` 136/0, `Opc.Ua.Positioning.Tests` and `Opc.Ua.Robotics.Intent.Tests` were all green; `MinimalRobotServer` was also started directly to confirm the hosted robotics path comes up. Three caveats, so the unchecked box above is not a mystery: the full suite was **not** run against .NET Framework locally; `Opc.Ua.OpenUsd.Tests` has one pre-existing failure on this machine (`StructuredCartesianCoordinatesAreAccepted` expects `"1.5"` and gets `"1,5"` — a German-locale decimal separator, unrelated to this change); and one pre-existing `CA1861` warning comes from `NodeSetImportIntegrationTests.cs`, which is byte-identical to `master` on this branch. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Opus 5 <noreply@anthropic.com> |

Import NodeSet2 documents into a fluent node manager (#4432)
## What
`INodeManagerBuilder.Import(UANodeSet, INodeSetImportFactoryProvider?)`
lets a source-generated (or hand-written fluent) node manager overlay a
NodeSet2 document that is only known at runtime onto the model it was
generated from.
Every document imported during one `Configure` pass forms a single batch
that is linked **exactly once** after the pass. A node may therefore
declare a `ParentNodeId` that lives in another document of the batch, or
a node the manager already owns — which is what makes an overlay
possible. Imported nodes resolve through
`Node(...)`/`NodeFromTypeId(...)` immediately, so they can be wired in
the same pass; they are registered with the manager when
`CompleteConfigureAsync` runs.
### Public surface
- **+1 method**: `INodeManagerBuilder.Import(UANodeSet nodeSet,
INodeSetImportFactoryProvider? factoryProvider = null)`.
- **+3 contracts** in `Opc.Ua.Server.Nodes`:
`INodeSetImportFactoryProvider`, `INodeSetImportFactory`,
`NodeSetImportDiscriminator` (TypeDefinition / MethodDeclaration /
NodeId).
- In `Opc.Ua.Export`: a public `UANodeSet.Import` overload taking a
`NodeSetImportStateFactory`, and a public batch
`LinkParentChildRelationships(context, nodes,
NodeSetImportLinkOptions)`. These replace what would otherwise have been
an `InternalsVisibleTo("Opc.Ua.Server")` on `Opc.Ua.Types`.
- `NodeState.IsExplicitlyDefinedChild(context, child)` and `protected
DetachExplicitlyDefinedChild(child)`, used to tell a generated slot
apart from an ordinary child.
### Typed states, no reflection
The generator emits `{Model}NodeSetImportFactoryProvider` — one factory
per model type/declaration, each calling a concrete constructor for an
*empty* state — and makes the generated node manager implement
`INodeSetImportFactoryProvider` by delegating to it. So the builder
resolves the provider from the manager (`NodeManager as
INodeSetImportFactoryProvider`); `Import` also accepts one directly, and
the generated manager exposes `partial void
AddNodeSetImportFactories(List<INodeSetImportFactory>)` for dependency
models. An imported node of a generated type materializes as its
generated `*State` subclass with no type lookup, which keeps the path
NativeAOT-safe.
Because the factories create empty states, an imported instance carries
exactly the children its document declares.
### Reconciliation
When an imported child lands in a slot the generated parent declares
(same BrowseName), it replaces the generated placeholder: the displaced
node and every descendant the document does not carry over are removed
from the manager, and references to them are retargeted at the
replacement. Replacing a node the same `Configure` pass already wired is
rejected with `BadInvalidState` rather than silently dropping the
wiring, and sealing a builder with an unregistered import batch is
rejected too.
### Also
- `RuntimeNodeSetNodeManager` now uses the same importer: its documents
are one batch, so a node may declare a parent in another document of the
group regardless of parse order, and duplicate NodeIds across documents
are detected while parsing.
- Linking resolves an imported child's reference type from its own
inverse reference (previously always `HasComponent`/`HasProperty`).
- Method import keeps the document's `UserExecutable`; it previously
copied `Executable` into it. View import keeps `EventNotifier`.
## Tests
- `NodeSetImporterTests` (15) — discriminator selection, generic
fallbacks, field/value/reference fidelity against a generic import,
cross-document linking, typed replacement of inherited and argument
slots, deferred linking preserving an application `Handle`, duplicate
NodeIds, factory misuse.
- `NodeSetImportBuilderTests` (15) — staging and lookup before
registration, batch linking, attaching to an existing node, provider
resolution, placeholder replacement with reference retargeting,
configured-placeholder rejection, seal/completion guards.
- `NodeSetImportIntegrationTests` (5) — a generated `[NodeManager]`
overlaying its own model on a running server: typed states through the
generated provider, cross-document linking, placeholder replacement, and
browse through a session.
- `NodeManagerGeneratorTests` (+4) — the emitted provider and the
manager's delegation, including that no factory uses
`Activator.CreateInstance`/reflection.
- `NodeSetAotTests` (+1) — the public state-factory import under
NativeAOT.
Full `Opc.Ua.Server.Tests` (4946), `Opc.Ua.SourceGeneration.Core.Tests`
(3821), `Opc.Ua.SourceGeneration.Tests` (165) and `Opc.Ua.Types.Tests`
pass locally on net10.0.

Drop the .Common suffix from the three GDS projects (#4438)
# Description Every other companion specification in the stack ships as `<Family>`, `<Family>.Client` and `<Family>.Server` — `Opc.Ua.Di`, `Opc.Ua.ISA95`, `Opc.Ua.Positioning`, `Opc.Ua.Robotics`, `Opc.Ua.Vision`, `Opc.Ua.WotCon`, `Opc.Ua.XRegistry`, and `Opc.Ua.Lds.Server` without a family package. GDS was the one exception, carrying a `.Common` suffix that named nothing. | Before | After | | --- | --- | | `src/Opc.Ua.Gds.Common` | `src/Opc.Ua.Gds` | | `src/Opc.Ua.Gds.Client.Common` | `src/Opc.Ua.Gds.Client` | | `src/Opc.Ua.Gds.Server.Common` | `src/Opc.Ua.Gds.Server` | ## No source changes were needed `RootNamespace` was already the final name in all three projects — the namespaces have always been `Opc.Ua.Gds`, `Opc.Ua.Gds.Client` and `Opc.Ua.Gds.Server`, and only `AssemblyName` and `PackageId` disagreed. Nothing that compiles against these assemblies changes a `using` directive; the diff outside the moves is entirely ids, paths and prose. Directories were moved with `git mv`, and every one of the 73 file moves is detected as a rename at 100% similarity (bar the handful that also had a name in their text), so `git log --follow` and blame survive. ## Consumer impact The package ids change, which is visible to anyone consuming the NuGet packages: | 1.5.378 package | 2.0 package | | --- | --- | | `OPCFoundation.NetStandard.Opc.Ua.Gds.Common` | `OPCFoundation.NetStandard.Opc.Ua.Gds` | | `OPCFoundation.NetStandard.Opc.Ua.Gds.Client.Common` | `OPCFoundation.NetStandard.Opc.Ua.Gds.Client` | | `OPCFoundation.NetStandard.Opc.Ua.Gds.Server.Common` | `OPCFoundation.NetStandard.Opc.Ua.Gds.Server` | `docs/migrate/2.0.x/packages.md` gains a renamed-packages section — it is the document that undertakes to cover NuGet renames, and had no GDS entry — and the migration skill's package table gains the two rows a 1.5.378 consumer needs. That is the only hand-written content in this PR; everything else is mechanical. Assembly names follow the package ids, so the section also notes that binding redirects, trimming descriptors and signing manifests naming the files directly have to be updated. ## Build infrastructure Everything naming the projects or their output moves with them: - `UA.slnx` and `tools/MigrationAnalyzer.slnx` (both re-sorted — the project lists are alphabetical, and `Gds` now sorts before `Gds.Client`). - `.azurepipelines/expected-packages.txt` — 3 ids, also re-sorted for the same reason. - `.azurepipelines/signlistDebug.txt` and `signlistRelease.txt` — 18 paths each. Their internal ordering is left alone: that group was already unsorted, and reordering a signing manifest is diff noise. - `samples/Reference/ConsoleReferenceServer/Dockerfile`, the two metapackage nuspecs, the analyzer nuspec's package dependencies, and 8 `.csproj` references across tests, samples and tools. `preview-pack.slnx` is generated from `UA.slnx` by `generate-slnx.ps1`, so there is nothing static to edit. Nothing under `.github/workflows`, and no `.ps1`/`.yml` in `.azurepipelines`, names these projects. The migration analyzer's shim tree mirrors the source project layout by its own documented convention, so `Gds.Client.Common/` becomes `Gds.Client/` and its readme table follows. ## Deliberately not changed Prose naming past work: `plans/23` still records that its deferral happened during the "GDS Client.Common modernization", which is the name that effort had. File *paths* in the same document were updated. ## Validation `net10.0`: - `UA.slnx`: 0 errors. 14 warnings, all pre-existing CA1861/CA1850/CA1307 in `XRegistry`, `Types.Tests` and `WotCon.Tests` — none in anything this PR touches. - Assemblies build as `Opc.Ua.Gds.dll`, `Opc.Ua.Gds.Client.dll`, `Opc.Ua.Gds.Server.dll`, with no `*.Common.dll` produced anywhere. - `Opc.Ua.Gds.Tests`: 1,116 passed, 0 failed, 54 skipped. - `Opc.Ua.MigrationAnalyzer.Core.Tests`: 10 passed, 3 skipped. - A repo-wide grep for the old names returns only the intentional old → new mappings in the migration docs. ## Checklist - [x] Existing tests pass - [x] No new tests — this is a rename with no behaviour change - [x] Consumer-visible package rename documented in the migration guide 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Opus 5 <noreply@anthropic.com> |

Complete fluent node manager extensibility (#4418)
# Description Complete the fluent node-manager extensibility surface needed by dynamic and externally backed address spaces. This change: - adds virtual node families with cheap NodeId ownership checks, async materialization, per-operation caching, custom browsing, and family-level callbacks; - adds monitored-item pre-creation decisions, complete lifecycle hooks, async batch hooks, stack-managed custom monitored items, and subscription-gated polling; - exposes the startup `ApplicationConfiguration` to generated manager partials through `FluentNodeManagerBase`; - fixes typed builder proxy support, concrete object wrapper types, and fully-qualified generated model composition; - reports unresolved `[NodeManager]` namespace expressions as `MODELGEN035` instead of silently dropping them; - documents the new APIs and compatibility behavior. ## Related Issues - Fixes #4397 - Fixes #4398 - Fixes #4399 - Fixes #4403 - Fixes #4404 - Fixes #4405 ## Validation - `Opc.Ua.Server.Tests` on `net10.0`: 4,886 passed, 5 skipped. - `Opc.Ua.SourceGeneration.Core.Tests` on `net10.0`: 3,807 passed, 8 skipped. - `Opc.Ua.SourceGeneration.Tests` on `net10.0`: 164 passed. - Runtime and generator regression selections passed on `net48`. - Review-feedback validation: 376 fluent tests passed on `net10.0`; 22 focused tests passed on `net48`. - The CI timing regression was repeated five times on `net48` and once on `net10.0`. - All 266 applicable GitHub Actions and Azure Pipelines checks, including CodeQL and coverage, pass on `83c571423`. - AppVeyor reports an immediate zero-duration no-run failure because `appveyor.yml` whitelists only the `appveyor` branch; it did not execute this PR. - `UA.slnx` builds successfully for `net10.0`; affected project builds are warning-free. - The repository-wide `dotnet test UA.slnx` invocation is currently blocked by the solution's mixed VSTest/Microsoft.Testing.Platform configuration under the .NET 10 SDK, so the affected test projects were run individually. ## Checklist - [ ] I have signed the [CLA](https://opcfoundation.org/license/cla/ContributorLicenseAgreementv1.0.pdf) and read the [CONTRIBUTING](https://github.com/OPCFoundation/UA-.NETStandard/blob/master/CONTRIBUTING.md) doc. - [x] I have added tests that prove my fix is effective or that my feature works and increased code coverage. - [x] I have added all necessary documentation. - [x] I have verified that my changes do not introduce (new) build or analyzer warnings. - [ ] I ran **all** tests locally using the **UA.slnx** solution against at least .net **framework** and .net **10**, and all passed. - [x] I fixed **all** failing and flaky tests in the CI pipelines and **all** CodeQL warnings. - [x] I have addressed **all** PR feedback received. --------- Copilot-Session: afaa67c9-fc97-4185-a785-edd54a937d95 |

Fix generated structured defaults and dependency metadata (#4414)
# Description Fix two source-generator paths that lost variable values or metadata: - XML `ExtensionObject` defaults without a `TypeId` now resolve their body through the encodeable factory's registered XML qualified name, decode to the generated structure, and retain the XML encoding identifier. - The existing preview `ModelDependencyV1` payload now carries effective child access and user-access values, minimum sampling interval, historizing state, and serialized default-value XML across referenced assemblies. The dependency validator rehydrates this metadata before inherited instance factories are generated. Explicit non-null extension-object TypeIds remain authoritative, unknown XML bodies remain raw XML, and explicit design files remain authoritative over referenced payloads. ## Related Issues - Fixes #4401 - Fixes #4402 ## Validation - Focused decoder, payload, validator, and Roslyn producer/consumer regressions on `net10.0` and `net48` - `tools/SourceGeneration.slnx` Debug builds on `net10.0` and `net48` - `tools/SourceGeneration.slnx` Release build on `net10.0` - Scoped `UA.slnx` Debug build on `net10.0` ## Checklist - [ ] I have signed the [CLA](https://opcfoundation.org/license/cla/ContributorLicenseAgreementv1.0.pdf) and read the [CONTRIBUTING](https://github.com/OPCFoundation/UA-.NETStandard/blob/master/CONTRIBUTING.md) doc. - [x] I have added tests that prove my fix is effective or that my feature works and increased code coverage. - [x] I have added all necessary documentation. - [x] I have verified that my changes do not introduce (new) build or analyzer warnings. - [ ] I ran **all** tests locally using the **UA.slnx** solution against at least .net **framework** and .net **10**, and all passed. - [ ] I fixed **all** failing and flaky tests in the CI pipelines and **all** CodeQL warnings. - [x] I have addressed **all** PR feedback received. --------- Copilot-Session: 66e6d342-d4a0-4d53-822b-524982c62f15 |

Fix OPC 10000-21 onboarding interoperability (#4385)
# Description Fix the four blockers that prevented the OPC 10000-21 onboarding registrar and client from working end to end: - generate every `ModelDesign` target independently, including multiple models in one directory, while preserving stable identifier CSV matching and cross-model dependencies; - ship the generated `Opc.Ua.Onboarding` constants, node states, encodeables, and typed clients from `Opc.Ua.Gds.Common`; - correct the standard `EncodedTicket` datatype to derive from `ByteString`; - align the new 2.0 `OnboardingClient` API with the generated `ArrayOf<ByteString>` / `ArrayOf<StatusCode>` contract; - make `BindToTicketStore` fully asynchronous, cancellation-aware, and assign the declared output slot instead of appending a second output; - add generated-model, client fallback, server binding, and in-process end-to-end regressions. The change also adds `samples/Gds/OnboardingRegistrar`, `samples/Gds/OnboardingClient`, and `run-onboarding-demo.ps1`. The demo loads the generated GDS and Onboarding models, restricts ticket administration to an ephemeral `RegistrarAdmin` user, proves anonymous access is denied, and completes a secure register/unregister round trip. The History CI follow-up rejects negative and non-finite processed-history intervals before provider dispatch and enforces the buffered aggregate output cap while calculator results are flushed. This prevents malformed requests from running until the client timeout, exhausting memory, delaying server teardown, and causing later alarm-event tests to fail. ## Related Issues - Fixes #4378 - Unblocks OPCFoundation/UA-.NETStandard-Samples#819 - Tracks the canonical model correction in OPCFoundation/UA-Nodeset#122 ## Validation - Full `net10.0` test projects: - `Opc.Ua.SourceGeneration.Core.Tests`: 3803 passed, 8 skipped - `Opc.Ua.SourceGeneration.Tests`: 143 passed - `Opc.Ua.Gds.Tests`: 1114 passed, 42 skipped - `Opc.Ua.History.Tests` with the CI coverage settings: 506 passed, 27 skipped - `HistorianDispatcher` tests: 88 passed on `net10.0`. - Invalid processed-history interval regressions passed on `net10.0` and `net48`. - Focused onboarding/source-generation regressions passed on `net48`. - `dotnet build UA.slnx -p:CustomTestTarget=net10.0 --no-restore` succeeded; the reported analyzer warnings are pre-existing in unchanged XRegistry/WoT files. - Packed all three GDS packages and verified the packaged `Opc.Ua.Gds.Common` assembly contains the generated Onboarding model surface. - `pwsh samples/Gds/run-onboarding-demo.ps1` verified anonymous denial and the authenticated secure ticket lifecycle. ## Checklist - [ ] I have signed the [CLA](https://opcfoundation.org/license/cla/ContributorLicenseAgreementv1.0.pdf) and read the [CONTRIBUTING](https://github.com/OPCFoundation/UA-.NETStandard/blob/master/CONTRIBUTING.md) doc. - [x] I have added tests that prove my fix is effective or that my feature works and increased code coverage. - [x] I have added all necessary documentation. - [x] I have verified that my changes do not introduce (new) build or analyzer warnings. - [ ] I ran **all** tests locally using the **UA.slnx** solution against at least .net **framework** and .net **10**, and all passed. - [ ] I fixed **all** failing and flaky tests in the CI pipelines and **all** CodeQL warnings. - [x] I have addressed **all** PR feedback received. --------- Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> Copilot-Session: 2d2c52c7-7040-4bd6-98de-aaf82ba7846b |

Fix instance TypeDefinition across dependency ModelDesign boundaries (#4355)
# Description The model source generator crashed with `MODELGEN003` / `NullReferenceException` whenever a `ModelDesign` instantiated an `ObjectType` (or `VariableType`) declared in a **dependency** design file, as soon as that type had children. The sibling of #4332 on the instance-declaration path: #4335 linked dependency *data types*, but an *instance* whose `TypeDefinition` lives in another design still crashed in `NodeStateGenerator` on the type's inherited children. Root cause: dependency design files load with `validateDictionary: false`, so `ValidateInstance` / `ValidateType` never ran on them and their types' children kept `TypeDefinitionNode` / `DataTypeNode` at `null`. When the target instance merged those children into its hierarchy (`BuildInstanceHierarchy` re-walks the dependency type's `Children.Items`), the null references were copied along, and `GetNodeStateClassName` dereferenced them while building the node state factory list. Changes: - A new best-effort `LinkDependencyInstances` pass in `ModelDesignValidator` links dependency-design instances the way `ValidateInstance` / `ValidateType` do for the target model: the `TypeDefinitionNode` / `DataTypeNode` of the types' children and standalone instances (recursively), variable `DataType` / `ValueRank` inheritance from the variable type, `DefaultValue` decoding, `VariableTypeDesign.DataTypeNode` restrictions, and method arguments — including creation of the `InputArguments` / `OutputArguments` argument properties so method children materialise into the target hierarchy exactly like local ones. Resolution is best effort (unresolvable references stay `null`) and NodeSet2 dependencies remain excluded, consistent with `LinkDependencyDataTypes`. - The pass runs alongside `LinkDependencyDataTypes`: for upstream dependencies after all of them are loaded and before the target validates (so the hierarchy merge picks up the links), and for downstream dependencies after they load. - `docs/ModelDependencies.md` documents the instance linking. Tests (all verified to fail with the exact reported NRE stack before the fix): - `CrossModelInstanceTypeDefinitionTests` (Core, 4 tests): the issue's minimal repro end to end; an equivalence test asserting the cross-model instance emits the **identical node-state factory set** as a locally declared type (this is the issue's stated expectation, and it drove the method-argument-property part of the fix); the flipped upstream/downstream ordering; and validator-level assertions that the merged hierarchy carries linked `TypeDefinitionNode` / `DataTypeNode` references, including the data type inherited from a dependency `VariableType`. - `CrossModelInstanceTypeDefinitionGeneratorTests` (Roslyn driver, 2 tests): the issue's csproj repro shape — both `AdditionalFiles` orderings, asserting no diagnostics and that the combined generated output of both models **compiles** (the instance factories reference the dependency model's typed state classes). Verified locally on net10.0: `Opc.Ua.SourceGeneration.Core.Tests` 3800 passed, `Opc.Ua.SourceGeneration.Tests` 141 passed, `Opc.Ua.SourceGeneration.Stack.Tests` 94 passed; 0-warning Release build of `Opc.Ua.SourceGeneration.Core` (all TFMs incl. netstandard2.0); `dotnet format whitespace --verify-no-changes` clean. This removes the last generator blocker for source generating the instance model of the `Workshop/DataTypes` sample (OPCFoundation/UA-.NETStandard-Samples#814): its `ParkingLot` / `DriverOfTheMonth` are instances of types declared in the other design file. ## Related Issues - Fixes #4353 ## Checklist _Put an `x` in the boxes that apply.

Fix [DataType] generator Clone() dropping every inherited field of a derived structure (#4354)
# Description
The `[DataType]` source generator emitted a `Clone()` that created a
fresh instance and copied only the fields declared on the annotated type
itself, so every field inherited from an `IEncodeable` base was silently
dropped. Since the server clones node values while loading an address
space, a derived structure served by a node manager came back out of a
Read with its inherited fields empty, even though encode/decode was
correct.
This PR makes the `[DataType]` path emit the same
`MemberwiseClone`-based shape as the model-based generator:
```csharp
/// <inheritdoc/>
public override object Clone()
{
return (DerivedStruct)this.MemberwiseClone();
}
/// <inheritdoc/>
public new object MemberwiseClone()
{
DerivedStruct clone = (DerivedStruct)base.MemberwiseClone();
// deep copy of the own reference-typed fields
return clone;
}
```
`Clone()` delegates to a generated `public new object MemberwiseClone()`
that starts from `base.MemberwiseClone()` — a shallow copy of the whole
object, inherited fields included — and then deep copies the type's own
reference-typed fields (encodeables, `DataValue`, `Variant`,
`ExtensionObject`). Derived classes hide `MemberwiseClone` and chain
into the base implementation, so deep-copy semantics compose across the
hierarchy, including across assemblies into model-generated base types
(the `BicycleType` scenario that surfaced this). The two generator paths
now agree.
Because the clone now starts from a full shallow copy
(`base.MemberwiseClone()` for classes, `with { }` for records), the
per-field clone emitter only writes the deep-copy assignments; the
redundant per-field plain copies are gone. This also fixes a latent side
bug in the class path: init-only simple fields were silently dropped by
the fresh-instance clone as well.
Records were already correct (`with { }` carries every field) and are
unchanged in shape.
Tests:
- `GenerateClassCloneUsesMemberwiseClone` /
`GenerateDerivedClassCloneCarriesInheritedState` assert the emitted
shape for root and derived classes.
- `DerivedClassCloneKeepsInheritedFields` runs the exact repro from the
issue through the Roslyn driver, emits the assembly, and executes
`Clone()` at runtime to prove the inherited field survives (verified on
net10.0 and net48).
Verified locally: `Opc.Ua.SourceGeneration.Core.Tests` (3798 passed),
`Opc.Ua.SourceGeneration.Tests` (140 passed),
`Opc.Ua.SourceGeneration.Stack.Tests` (94 passed), and
`Opc.Ua.Client.Tests` (2161 passed, exercises the regenerated in-tree
`[DataType]` record types). The in-tree `[DataType]` consumers
(Opc.Ua.Client, both GDS common projects) regenerate and build without
warnings.

Fix structure subtyping across dependency ModelDesign boundaries (#4335)
# Description The model source generator crashed whenever a `ModelDesign` declared a structure that subtypes a structure from **another** design file (`MODELGEN003` with a `NullReferenceException`), and the cross-assembly `[assembly: ModelDependency]` flow failed even earlier with `The BaseType reference ... is not the expected type: DataTypeDesign`. Structure inheritance across model boundaries — the primary use case of companion-spec layering — could not be source-generated at all. Three root causes, all in the dependency-loading path of the validator: 1. **Dependency design files were never linked.** They load with `validateDictionary: false`, so their `DataTypeDesign`s kept `BasicDataType` at the enum default (`Boolean`) and their fields' `DataTypeNode` stayed `null`. `BinarySchemaGenerator`'s inherited-field merge then dereferenced the null `DataTypeNode`, and `XmlSchemaGenerator` / `DataTypeGenerator` silently emitted `xs:boolean` / `bool` from the default classification. 2. **Dependencies that import the target crashed at load.** Each generation group receives every design file of the compilation as a dependency, including downstream models that import the group's target — those loaded *before* the target they import and failed resolving their `BaseType`. This produced the confusing `AdditionalFiles`-order-dependent failure modes. 3. **The payload flow never reached ModelDesign targets.** `ModelCompilation` supplied `referencedDependencies` only to the NodeSet2 pass, never to the design-file pass, and payload-materialised data types lacked the classification and field links needed to serve as base types of local structures. Changes: - `ModelDesignValidator.ValidateModel` loads dependencies in two phases around the target: upstream models first (topological, referenced models before their referrers), then the target, then models that import the target. - A new `LinkDependencyDataTypes` pass classifies dependency data types (`IsStructure` / `IsEnumeration` / `BasicDataType`) and resolves field `DataTypeNode` / `Parent` best effort. It runs for payload-imported declarations and upstream design-file dependencies before target validation, and for downstream dependencies after they load. NodeSet2 dependencies are excluded — `NodeSetToModelDesign` already links and classifies them with its own semantics. - Payloads for models that are backed by a design file in the compilation are skipped — the explicit file is authoritative (previously, importing both crashed with duplicate symbolic ids). - Payload-materialised data types honor the payload's `IsEnumeration` flag. - The design-file `GenerateCode` pass now receives the referenced assemblies' dependency payloads (`ModelCompilation` + new optional `referencedDependencies` parameter). - `docs/ModelDependencies.md` updated accordingly. Tests (all verified to fail with the exact reported errors before the fix): - `CrossModelStructureSubtypeTests` (Core, 6 tests): the issue's minimal repro end to end — asserting the emitted `.bsd` carries inherited fields with correct types and `SourceType`, the `.xsd` extends the dependency structure (not `xs:boolean`), and the generated C# derives correctly — plus the reversed target/dependency order, both payload flows at generation and validator level, and a three-level chain (target → payload structure → design-file structure). - `CrossModelStructureSubtypeGeneratorTests` (Roslyn driver, 3 tests): both `AdditionalFiles` orderings compiling the generated output, and the full cross-assembly flow (producer assembly generated from the upstream design; consumer resolves the base structure from the reference's payload without re-emitting it). Verified locally on net10.0: `Opc.Ua.SourceGeneration.Core.Tests` 3786 passed, `Opc.Ua.SourceGeneration.Tests` 135 passed, `Opc.Ua.SourceGeneration.Stack.Tests` 94 passed; 0-warning Release builds of `Opc.Ua.SourceGeneration.Core` (all TFMs incl. netstandard2.0), both Roslyn generator variants, Stack and Tester.

Fully support sub-state machines in the fluent state-machine builder (#4322)
# Description Part 16 §B.3 places `HasSubStateMachine` on the parent **state** node, but the fluent builder attached it to the state-machine **root** because `FluentFiniteStateMachineState` never materialized state nodes at all. Investigating #3821 showed the gap was wider than the reference placement: 1. **No state nodes existed.** The NodeId written into `CurrentState/Id` — `new NodeId(stateId, ElementNamespaceIndex)` — was **dangling**: no node with that id was in the address space. 2. **`AvailableStates` was never populated**, so `GetAvailableStatesAsync` returned empty against a fluent-built server. 3. **The whole client discovery chain was therefore dead.** `ObserveEffectiveStateAsync` enumerates `AvailableStates` and browses `HasSubStateMachine` from each state node — it found nothing. The client side was already spec-correct; only the server deviated. 4. **`HasSubStateMachine` is non-hierarchical** (a subtype of `NonHierarchicalReferences`, `i=32`). Using it as the sub-SM's `BaseInstanceState.ReferenceTypeId` left the sub-SM unreachable from a hierarchical browse of the machine. ## What changed **Element nodes are materialized.** Definition-mode machines now create one `StateType` node per declared state and one `TransitionType` node per declared transition — each a `HasComponent` child carrying `StateNumber` / `TransitionNumber`, with the §B.4 `FromState` / `ToState` / `HasEffect` references and `HasCause` added by `WithCause`. `AvailableStates`, `AvailableTransitions` and `LastTransition` are populated, so `CurrentState/Id` and `LastTransition/Id` resolve to real, browsable nodes. NodeIds are per-instance, so several machines built from one definition coexist. **`HasSubStateMachine` moved to the state node**, with the inverse `SubStateMachineOf`, and the sub-SM is attached as a `HasComponent` child (fixing 4). **Core gains element-id mapping hooks.** `GetCurrentStateId` / `UpdateStateVariable` / `UpdateTransitionVariable` hard-coded the numeric form and were non-virtual, so a subclass could not redirect them. They now route through `public virtual` `GetStateNodeId` / `GetStateId` / `GetTransitionNodeId` / `GetTransitionId`, whose defaults reproduce the previous `(elementId, ElementNamespaceIndex)` convention **exactly** — every stack-shipped and generator-emitted machine is unaffected, and there is a regression test asserting that. **Generated machines report their model namespace.** The generator now emits an `ElementNamespaceUri` override on `FiniteStateMachineType` subtypes, taken from the nearest type that actually *declares* state children — a subtype that only adds behaviour inherits its elements, and their namespace, from its base. **Ordering and validation fixes.** `WithSubStateMachine` and `WithInitialState` are now order-independent (previously, attaching a sub-SM before setting the initial state left the child suspended until the parent left and re-entered the state — silently). `WithSubStateMachine` validates `parentStateId`, and the builder rejects duplicate element browse names, since element NodeIds are now derived from them. ## A defect this surfaced Code that assembles nodes with the generated `CreateInstanceOf<Type>` factories never calls `NodeState.CreateAsPredefinedNode`, so `OnBeforeCreate` / `OnAfterCreate` are skipped for the entire subtree — and `OnAfterCreate` is the only place a state machine resolves its element namespace. It is also where `ConditionState` binds its `Enable` / `Disable` / `AddComment` handlers and `AlarmConditionState` binds the shelving methods, so the impact is broader than state machines. This PR fixes only the two call sites it depends on — DI's `SoftwareUpdateFacetWiring` and Robotics' `RoboticsOperationBuilder`. **The repository-wide audit is deliberately left out of scope and tracked in #4320** (24 files call these factories; none completed the lifecycle). The Robotics regression had no test coverage at all, so an assertion on `CurrentState/Id` was added and verified to fail without the fix. ## Breaking changes - Sub-state machines are **no longer browsable from the state-machine root**. Callers passing a machine's `ObjectId` to `GetSubStateMachineAsync` must pass a state NodeId instead — from `GetAvailableStatesAsync` or a snapshot's `CurrentStateId`. - `CurrentState/Id` for fluent machines changes from the numeric form to the materialized node's id. Code reading a numeric id out of it should call `FiniteStateMachineState.GetStateId` rather than parsing the identifier. - Generated machines qualify `CurrentState/Id` / `LastTransition/Id` with their companion-spec namespace instead of the OPC UA one. Documented in `docs/WhatsNewIn2.0.md` and `docs/StateMachines.md`. ## Notes for reviewers - Adding `virtual` to the `FiniteStateMachineState` members is a binary (not source) breaking change — assumed acceptable on the 2.0 line, but worth confirming against the compatibility policy. - Address-space cost is one node plus one property per declared state and transition, per machine instance; called out in the docs for servers instantiating many machines. - `AvailableTransitions` is modelled as a `HasComponent` `BaseDataVariable` (matching the standard NodeSet and what the client's browse path expects), not a Property. ## Related Issues - Fixes #3821 - Surfaced #4320 (node create lifecycle audit — not addressed here) ## Checklist - [ ] I have signed the [CLA](https://opcfoundation.org/license/cla/ContributorLicenseAgreementv1.0.pdf) and read the [CONTRIBUTING](https://github.com/OPCFoundation/UA-.NETStandard/blob/master/CONTRIBUTING.md) doc. - [x] I have added tests that prove my fix is effective or that my feature works and increased code coverage. - [x] I have added all necessary documentation. - [x] I have verified that my changes do not introduce (new) build or analyzer warnings. - [ ] I ran **all** tests locally using the **UA.slnx** solution against at least .net **framework** and .net **10**, and all passed. - [ ] I fixed **all** failing and flaky tests in the CI pipelines and **all** CodeQL warnings. - [ ] I have addressed **all** PR feedback received. ### Test runs (net10.0) | Suite | Result | |---|---| | `Opc.Ua.Server.Tests` (full) | 4734 passed, 5 skipped | | `Opc.Ua.SourceGeneration.Core.Tests` | 3780 passed | | `Opc.Ua.SourceGeneration.Tests` | 132 passed | | `Opc.Ua.SourceGeneration.Stack.Tests` | 94 passed | | `Opc.Ua.Types.Tests` | 8763 passed | | `Opc.Ua.Robotics.Tests` | 540 passed | | `Opc.Ua.Robotics.Intent.Tests` | 22 passed | | `Opc.Ua.Di.Tests` | 424 passed | | `Opc.Ua.ISA95.Tests` | 136 passed | | `Opc.Ua.Aas.Tests` | 670 passed | | `Opc.Ua.Positioning.Tests` | 69 passed | | `Opc.Ua.Client.Tests` (StateMachines) | 36 passed | Only net10.0 was run locally; the .NET Framework leg is left to CI, hence the unchecked box above. --------- Co-authored-by: Claude Opus 5 <noreply@anthropic.com> Co-authored-by: copilot-swe-agent[bot] <198982749+Copilot@users.noreply.github.com> Co-authored-by: marcschier <11168470+marcschier@users.noreply.github.com> |

Fluent: publish Configure-created nodes' references on foreign-manager nodes (Objects folder placement) (#4331)
# Description A node created inside the fluent `Configure` hook (source-generated `[NodeManager]` partial, or the hosting `AddNodeManager(uri, build)` route) had no way to appear below the Objects folder — or below any node owned by another node manager. `AsyncCustomNodeManager.AddReverseReferencesAsync` mirrors inverse references into the `externalReferences` dictionary **before** the `Configure` partials run, and the fluent surface never sees the dictionary, so a configure-created node with an inverse `Organizes` reference to `ObjectsFolder` existed and simulated but never showed up under Objects. This implements the three coordinated pieces proposed in #4329, plus the companion namespace gap: **1. Idempotent mirroring pass** (independently worthwhile hardening) - `AddExternalReference` in `AsyncCustomNodeManager` and `CustomNodeManager2` now has if-missing semantics (linear scan of the per-source list). - `TypeTable.AddEncoding` no longer appends a duplicate encoding id; re-registering the same encoding is a succeeding no-op. (`AddRootNotifierAsync` and the node-side `AddReferenceIfMissing` branch were already idempotent.) **2. Re-run the pass after `Configure`** - New protected `FluentNodeManagerBase.CompleteConfigureAsync(externalReferences, ct)` wraps `AddReverseReferencesAsync` so hand-written managers using `CreateFluentBuilder` benefit too. - The generator-emitted `CreateAddressSpaceAsync` and the hosting `FluentNodeManager` invoke it once between the `Configure` callbacks and `Seal()`. Timing is safe: the master distributes `externalReferences` only after every manager's `CreateAddressSpaceAsync` returns. Side benefit: inverse `HasNotifier` references on configure-created event sources get root-notifier registration for free. - The hosting `FluentNodeManager`'s hand-rolled `externalReferences` workaround for its root folder is deleted — the root's inverse `Organizes` reference now flows through the shared pass (mirrored exactly once, covered by a test). **3. Discoverable fluent sugar** - `OrganizedBy(parentId)` / `UnderObjectsFolder()` on `INodeBuilder` write the inverse `Organizes` reference; with piece 2, placement is just "write the inverse reference". - A parentless `CreateInstance<TState>` on `INodeManagerBuilder` takes a constructor-style factory (`p => new BoilerState(p)`, keeping the surface reflection-free and AOT-safe), materializes the subtree from the type model via `NodeState.Create`, rebases all NodeIds through the manager's `INodeIdFactory` (`AssignInstanceNodeId`/`AssignInstanceChildNodeIds` — the same pair the generated factories use, so declaration-id children cannot collide with the type model), and registers via `AddPredefinedNodeSynchronously`. The Boiler #2 shape becomes fully fluent: ```csharp builder.CreateInstance( new QualifiedName("Boiler #2", NamespaceIndexes[1]), p => new BoilerState(p)) .Configure(n => n.UnderObjectsFolder()); ``` **Companion gap, same theme:** `[NodeManager]` grows `AdditionalNamespaceUris`, flowing through attribute discovery → binding → generator so the generated constructor reports a second (instance) namespace at construction and the generated factory advertises it in `NamespacesUris` — today `SetNamespaces` after construction is not enough because `MasterNodeManager` builds its namespace routing from what the manager reported when it was built. **Scope boundary** (as discussed in the issue): startup-time configuration only; for nodes created after startup the correct primitive remains `IMasterNodeManager.AddReferencesAsync`. **Reviewer notes** - The generated-code change was validated against the real pipeline: a forced fresh compile of `Opc.Ua.Server.Tests` (whose CoverageNodeSet managers are `[NodeManager]`-generated) emits `await CompleteConfigureAsync(externalReferences, cancellationToken)` between `Configure` and `Seal()` and compiles against the real base class. - The distribution consumer (`AddReferencesAsync`) already used `AddReferenceIfMissing`, so the whole chain is defense-in-depth idempotent. - 15 new tests: double-run idempotence, second-pass pickup of late-registered nodes, the new reference sugar, root-instance creation incl. child-id rebasing and reference remapping, hosting end-to-end Objects-folder placement, emitted-sequence and `AdditionalNamespaceUris` generator tests, and a full Roslyn-pipeline attribute test. Docs updated in `docs/NodeManagers.md` (new "Creating nodes under other managers' nodes" section, attribute docs, fluent-surface sections). - Verified locally: all touched projects build with 0 warnings; full `Opc.Ua.Server.Tests` (4,725 passed / 0 failed / 5 skipped, net9.0), `TypeTableTests` (113), `Opc.Ua.SourceGeneration.Core.Tests` (41), `Opc.Ua.SourceGeneration.Tests` (132), and the Quickstarts.Servers sample all pass. ## Related Issues - Fixes #4329 - Motivating case: OPCFoundation/UA-.NETStandard-Samples#756 / OPCFoundation/UA-.NETStandard-Samples#795 (Workshop/Boiler migration) ## Checklist - [x] I have signed the [CLA](https://opcfoundation.org/license/cla/ContributorLicenseAgreementv1.0.pdf) and read the [CONTRIBUTING](https://github.com/OPCFoundation/UA-.NETStandard/blob/master/CONTRIBUTING.md) doc. - [x] I have added tests that prove my fix is effective or that my feature works and increased code coverage. - [x] I have added all necessary documentation. - [x] I have verified that my changes do not introduce (new) build or analyzer warnings. - [ ] I ran **all** tests locally using the **UA.slnx** solution against at least .net **framework** and .net **10**, and all passed. - [ ] I fixed **all** failing and flaky tests in the CI pipelines and **all** CodeQL warnings. - [ ] I have addressed **all** PR feedback received. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Fable 5 <noreply@anthropic.com> |

Generate ReferenceNodeManager address space from a NodeSet2 model (#4220)
# Description The CTT/compliance `ReferenceNodeManager` built its ~6,000 node address space entirely in imperative C#. This PR migrates it to a source-generated `[NodeManager]` partial driven by an exported NodeSet2 model (`ReferenceServer.NodeSet2.xml`), mirroring the `MinimalBoilerServer` sample and completing the goal of issue #4204. The address space is now materialized from the model by the source generator. The large orchestration body was kept but converted from create-based to **find-instead-of-create**: each `Create*` primitive now looks up the model-materialized node via `FindPredefinedNode<T>` and re-applies runtime values, DataAccess metadata, and write handlers, rather than constructing nodes from scratch. This keeps the deterministic value seeding and behavior wiring intact while the structure comes from the model. ## Notable details for reviewers - **Idempotent reference wiring.** The mesh references in the `References` folder are already present in the model, so the historic manual `AddReference` calls would throw on duplicates. Added a small `AddReferenceIfMissing` helper so those calls are safe. - **Non-string NodeIds.** The `NodeIds` folder assigns numeric / GUID / opaque NodeIds. The model exports those nodes with their final ids, so find-by-string-path no longer works; added `CreateVariableById(NodeId)` to locate them by their real id. - **Generator bug fix (worth a careful look).** `ModelDesignExtensions.GetValueRankAsCode` reconstructed `ValueRank` as `dimensions.Length + 1`, so a node with `ArrayDimensions="3,3"` was emitted as `ValueRank = 3`. This affected **any** NodeSet2 with a fixed multi-dimensional array (rank-3 matrices, `BadTypeMismatch` on whole-matrix writes, wrong decoded dimensions). Corrected to `dimensions.Length` and updated the unit tests that had codified the off-by-one. ## Validation - `ReferenceServerTest`: 44/44 on net10.0 and net48 - `Opc.Ua.SourceGeneration.Core.Tests`: pass on net8.0/net9.0/net10.0/net48 - Integration on net10.0: ComplexTypes, Client, History, Sessions, Subscriptions all pass - Clean build, no new analyzer warnings ## Related Issues - Fixes #4204 ## Checklist _Put an `x` in the boxes that apply.

Emit WriteMask from the model in the source generator (#4253)
## Summary Isolates a self-contained OPC UA source-generator bug fix, extracted from PR #4220 (which targets a different base branch) so it can merge independently against `master`. ## Fix: Emit node WriteMask from the model **Bug:** The `NodeState` source generator hardcoded `global::Opc.Ua.AttributeWriteMask.None` for both the `WriteMask` and `UserWriteMask` attribute replacements. As a result, attributes declared writable in a NodeSet2 model (for example `WriteMask=96`) were emitted as `None`, so writes to those attributes failed with `BadNotWritable`. **Change:** - `tools/Opc.Ua.SourceGeneration.Core/Generators/NodeStateGenerator.cs` - the common node replacements now emit `root.GetWriteMaskAsCode()` for the `WriteMask` and `UserWriteMask` tokens instead of the hardcoded `AttributeWriteMask.None`. - `tools/Opc.Ua.SourceGeneration.Core/Schema/ModelDesignExtensions.cs` - adds a `GetWriteMaskAsCode(this NodeDesign node)` helper that returns `global::Opc.Ua.AttributeWriteMask.None` when `WriteAccess == 0`, otherwise `(global::Opc.Ua.AttributeWriteMask){writeMask}`. ## Tests - `tests/Opc.Ua.SourceGeneration.Core.Tests/Schema/ModelDesignExtensionsTests.cs` - adds `[TestCase]`-driven coverage for `GetWriteMaskAsCode` across representative write-mask values plus a null-node test. ## Validation - `dotnet build tools\Opc.Ua.SourceGeneration.Core\Opc.Ua.SourceGeneration.Core.csproj -c Release` - 0 warnings, 0 errors. - `dotnet test tests\Opc.Ua.SourceGeneration.Core.Tests\Opc.Ua.SourceGeneration.Core.Tests.csproj -f net8.0 -c Release` - 3775 passed, 0 failed, 8 skipped. ## Note on the Views fix (excluded) A second generator fix (preserve forward same-namespace `Organizes` references to `ViewDesign` targets in `NodeSetToModelDesign`) was intended to ship here as well, but it was excluded. That fix compensates for behavior introduced by #4220 where imported Views are promoted to top-level `ViewDesign` nodes and their `ParentNodeId` is cleared. On `master` that promotion does not happen (Views remain children of their folder), so the fix and its test do not apply and cannot be cleanly isolated. It will land with #4220.

Import NodeSet2 Views as standalone top-level nodes in the source generator (#4259)
## Problem The NodeState source generator mishandled `UAView` nodes imported from a NodeSet2 model. When an exporter set a View's `ParentNodeId` to an organizing folder, the importer/generator absorbed the View into that folder's `Children` and tried to emit an invalid `AddChild(...)` call. Because `ViewState` derives from `NodeState` (not `BaseInstanceState`), a View can never be an `AddChild` component, so the generated code was invalid. ## Fix Make Views standalone top-level predefined nodes linked purely via `Organizes` references — mirroring how `DataType`/`ReferenceType` type nodes and `DataTypeEncoding` are handled: - **`tools/Opc.Ua.SourceGeneration.Core/Schema/NodeSetToModelDesign.cs`** — clear the `UAView` `ParentNodeId` so the View stays a standalone top-level node, keep the organizing folder's forward `Organizes` references to those Views, and carry the View's `ContainsNoLoops` attribute through to the `ViewDesign`. - **`tools/Opc.Ua.SourceGeneration.Core/Generators/NodeStateGenerator.cs`** — return `null` for `ViewDesign` in the `AddChild` and `ReplaceChild` template paths so Views are never emitted as components. - **`tests/Opc.Ua.SourceGeneration.Core.Tests/Schema/NodeSetToModelDesignTests.cs`** — new `ViewImport` NodeSet constant and `ImportPreservesFolderOrganizesReferencesToViews` test verifying Views are imported as top-level nodes while the organizing folder retains its forward `Organizes` references to them. ## Validation - `dotnet build tools\Opc.Ua.SourceGeneration.Core` (Release): 0 warnings / 0 errors. - `dotnet test tests\Opc.Ua.SourceGeneration.Core.Tests` (net8.0, filtered to `NodeSetToModelDesign`): all 17 tests pass, including the new `ImportPreservesFolderOrganizesReferencesToViews`. Extracted from the larger PR #4220 work — this PR contains only the source-generator View fix (no WriteMask, UserAccessLevel, NodeSet2.xml, or ReferenceNodeManager changes).

Fix off-by-one ValueRank in the NodeState source generator (#4258)
## Summary `ModelDesignExtensions.GetValueRankAsCode` in the NodeState source generator computed the ValueRank for a fixed-size multi-dimensional `ArrayDimensions` string (e.g. `"3,3"`) as `dimensions.Length + 1`, which over-counted the rank by one. The number of comma-separated entries in `ArrayDimensions` already **is** the ValueRank — `"3,3"` is a two-dimensional array with ValueRank `2`, not `3`. ## Changes - `dims = dimensions.Length + 1` → `dims = dimensions.Length` (entry count already equals the ValueRank). - Added a guard: when there are zero entries (empty or all-commas `ArrayDimensions`, which `Split(..., RemoveEmptyEntries)` reduces to length 0), the method now returns `OneOrMoreDimensions`. - Refreshed the stale explanatory comment / removed the obsolete `TODO`. - Updated the `GetValueRankString_*` unit tests in `ModelDesignExtensionsTests.cs` to the corrected expected ranks. ## Validation - `dotnet build` of `Opc.Ua.SourceGeneration.Core` (Release): 0 warnings / 0 errors. - Filtered `GetValueRankString` tests on net8.0: 18/18 passed. Extracted from the larger PR #4220 work; this PR contains **only** the ValueRank fix (two files). Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com> |

Robot intent: a task-level command API with a Part 10 lifecycle (#4165)
# Description Implement the draft **OPC UA — Robot Intent** companion model end to end: task-level motion verbs, a Part 10 lifecycle, a server hosting surface, a client, two samples and a live integration suite. It replaces the opt-in convention API merged in #4127 with an implementation generated from a companion information model. ## Why OPC 40010-1 *Robotics* describes robot **topology** in detail and defines **no motion verbs at all** — its entire actuation surface is `Start`, `Stop` and loading a named program. A conformant client can discover everything about a robot's construction and cannot ask it to move anywhere. #4127 filled that gap with ten verbs in an application-owned namespace, resolved by BrowseName, and the file said what it was: *"opt-in, explicitly non-normative industrial operation conventions"*. That contribution established a **vocabulary**. It established no **lifecycle**, and the lifecycle is the harder half. A motion takes seconds; a pick takes a minute. OPC 10000-4 §5.12.2 discards a method result when the Session ends *"independent of the task actually performed at the Server"* — so a synchronous motion method does not merely time out, it **loses the outcome of work that has already physically happened**. OPC 10000-10 §4.1 gives the OPC Foundation's own resolution: a Method performs a calculation, a **Program** runs a batch process or a machine tool part program. So `SubmitIntent` returns as soon as the intent is *admitted*, and what it returns is a NodeId — an `IntentOperationState` (a Part 10 program instance) the client subscribes to for progress and reads for the result. ## What changed **Model and shared code** — `Opc.Ua.RobotIntent.NodeSet2.xml` is source-generated in `Opc.Ua.Robotics`, so the enums, the polymorphic intent structures, `IntentOperationState : ProgramStateMachineState`, the method states and the typed clients derive from the model rather than being hand-written. Its only `RequiredModel` is the base UA namespace, so a server can adopt it without OPC 40010 or DI. `PoseMath` implements the specification's Annex C conversion between its unit quaternion and the core `ThreeDFrame` — including the `asin` clamp that stops a pole orientation becoming a domain error, and the non-negative-`w` representative that makes two servers agree on four numbers. `FrameTree` composes transforms along the frame tree. **Verbs are a DataType hierarchy, not one Method each.** A single submission and a mission step are then the same shape, and a new intent is a subtype rather than a new method — which is what `AddOperation<TRequest,TResponse>` was working around. **Server** — `IntentControllerHost` owns admission in the specification's order, the queue with PLCopen buffer modes, blending, cancellation *with the server's right to refuse*, missions with a committed base and a revisable horizon plus an IEC 61131-3 step graph, safety-aware refusals, real-time channel brokerage, and the capability declaration. All thirteen Methods are wired; command authority and channel leases are released when the holding Session closes; every client-supplied NodeId is validated against the controller being commanded (clause 11.3). `RobotIntentNodeManager`, the fluent `IIntentControllerBuilder` and `AddRobotIntent`/`ConfigureRobotIntent` make it reachable, and `RobotIntentFacetCalculator` computes which of the specification's facets an instance actually satisfies. **Client** — `RobotIntentClient` discovers `Server/RobotIntent/Controllers` and reads what a robot accepts; `IntentOperationHandle` subscribes and completes on a terminal state, recovering the result after a reconnect because clause 6.7 promises it survives; `CommandAuthorityLease` and `RealTimeChannelLease` manage the two exclusive resources; fluent builders cover every intent and mission. **Samples** — all robotics samples move under `samples/Robotics/`. `IntentEnabledRobot` is one UR5e-style offset-wrist arm on a bench, declared completely enough to show what a conformant server publishes, with a simulated safety source so the clause 10.4 refusals are demonstrable. `IntentViewerClient` turns a **click on a target prim in the OpenUSD viewport** into an intent and watches the arm execute it; it also runs headless, which is how CI exercises it. **Intents execute serially**, which satisfies every `BlockingMode` constraint by construction: the specification forbids beginning a `Single` or `Hard` intent while another executes and merely *permits* `None` and `Soft` to overlap. The convention API (`RoboticsOperationConventions`, `RoboticsOperationsBuilders`, `RoboticsOperationsClient`) is removed. ### On safety — what this deliberately does *not* claim The interface is **non-safety-rated**, and that is a property of the technology rather than a scoping choice. OPC 10000-15 carries cyclic safety data from a SafetyProvider to a SafetyConsumer; the consumer's `RequestSPDU` holds an identifier, a monitoring number and one octet of explicitly **non-safety** flags, so a caller has no channel through which to supply safety-rated arguments. Every safety fieldbus (PROFIsafe, CIP Safety, FSoE, openSAFETY) expresses a safety command as a **continuously asserted cyclic signal**, because the integrity argument rests on the fail-safe state that follows when assertion *stops* — and a Method call has no defined behaviour when it stops being called. What the host does instead is **observe and refuse**: `UpdateSafetyState` is how the application reports what the safety system is enforcing, and admission then refuses on the same values a client can read, so a refusal is explainable from the address space rather than from Server-internal state. It may never *instruct* the safety system, and no Method here commands a safe motion function, changes an operational mode or clears a stop. ## Defects this found in the specification, fixed upstream Implementing a specification is the only way to find out whether it can be implemented. Seven defects went back to [marcschier/opcua-drafts#47](https://github.com/marcschier/opcua-drafts/pull/47) rather than being worked around here: - **Refusal was unobservable.** Clause 6.2 orders six distinct refusals and clause 5.8 calls the failure set "small and diagnosable on purpose" — but `SubmitIntent` returned only `IntentId` and `Operation`, so a client could see *that* something was refused and never *which*. It now returns `Accepted`, `Failure` and `Message`, and clause 6.2 states that a refusal returns `Good` rather than substituting a Bad `StatusCode`. - **The Part 10 promotion was illegal.** `IntentOperationType.ProgramDiagnostic` was declared as a Property of `PropertyType`; OPC 10000-10 declares it a Variable of `ProgramDiagnostic2Type` reached by `HasComponent`. The declaration added a *second* member beside the inherited one instead of promoting it — which is precisely why an earlier version of this branch had deleted it. Correcting the TypeDefinition made it generate cleanly with **no change to the curated Core**. - **Clause 9 said nothing about the Method surface.** A server could declare `MissionsSupported` true and omit `SubmitMission` entirely, because the mission and channel Methods are Optional. This implementation did exactly that until an integration test caught it. A fourth honesty rule and a table now fix which Methods each declaration implies. - **Conformance was not machine-readable, and two implementations disagreed.** Clause 12 defined conformance in terms of facets and gave a Server nowhere to publish which ones it satisfied, so every client had to re-derive Table 12.2 from the address space. This repository proved why that fails: the server''s `RobotIntentFacetCalculator` and the client''s `RobotIntentRules.DeriveFacets` each implemented clause 12.2 independently and **disagreed on essentially every row** — the client''s `Blending` was `BlendingSupported` alone where the server also requires all four blending buffer modes, its `QueuedIntents` was `MaxQueueDepth > 0` where the server also requires `Buffered`. A client and server from the same release answered "does this controller conform?" differently, and both were reading the specification correctly, because several rows are behavioural and no amount of browsing settles them. `IntentCapabilitiesType` now carries **`SupportedFacets`**, exactly as OPC 10000-5 does with `ServerCapabilitiesType.ServerProfileArray`, RI-Base requires it, and clause 12.2 separates structural requirements a Server shall meet before listing a facet from attested ones governed by clause 9. - `WaitIntentDataType.Signal` was unbounded where clause 11.3 has to check it; §11.3 gained a table fixing the expected type of every NodeId-valued member; §5.7.0 gave `Ready`/`ActiveIntent`/`ActiveMission` normative meaning; §6.9 bounded `RequestedLease`; §6.5 and §6.4 now say what a server that cannot differentiate `StopMode` must do, and which stop a superseded intent gets. ## Bugs the tests and reviews caught Each of these would have been silent in the field: - **The execution engine was never wired into the public API.** `IntentControllerBuilder.RegisterAsync` built the address space and never started an `IntentControllerHost`, so through the documented `AddRobotIntent` → `ConfigureRobotIntent` path **every Method returned `BadNotImplemented`** and the registered `IIntentExecutor` was never resolved. A browsable address space is not a working robot interface, and only a live integration test showed the difference. - **NodeId scoping failed open on an empty index.** A controller advertising `CallProgramIntentDataType` with no published `ProgramType` accepted an *arbitrary* NodeId as `CallProgram.Program` — and `CallProgram` runs code the server holds. - **Blending completed the predecessor at submission time** and abandoned its motion, telling the client it succeeded and publishing an all-zero pose at the origin as a genuine `AchievedPose`. - **Mission base immutability compared only identifiers**, so a client could keep the ids and swap the *motion* of an already-committed step. - **`FinalResultData/Result` was never registered** with the node manager: Browse showed it, Read returned `BadNodeIdUnknown` — so clause 6.7's promise to a Part 10 client did not hold. - `DisposeAsync` disposed primitives out from under in-flight executor code; re-using a terminated `IntentId` destroyed the retained result and duplicated a NodeId; neither side registered the Robot Intent encodeables, so `Pose3DDataType` did not decode; host startup was hooked to a task that ran in only one hosting shape. - The result was published **after** the state went terminal; capabilities were resolved against a stale namespace table; an empty `ContentFilter` arrives as an empty element array rather than a null filter, so testing only for null made every unconditional mission transition silently untaken — a mission would run its first step and stop. ### Found by a later test-quality audit, after the above was written An audit of the test suite itself found five tests whose **names** asserted a normative requirement while their **code** asserted something weaker or nothing at all. The worst **fabricated the answer it checked**: a helper caught a decode failure and invented "5 supported intents, 6 axes, all facets true", so six capability-honesty assertions across four tests could pass while reading nothing from the server. The fallback is gone and the suite passes with honest reads. Chasing the facet gaps it reported led to the clause 12 defect above. Two further defects followed from completing that work: - **`RI-Interop-40010` was never computed**, and the code documented the omission as impossible to fix "because the calculator receives only a Robot Intent controller, not the linked OPC 40010 model". That was wrong: Annex B's structural requirement is an **inverse** `HasIntentController` reference, reachable from `IntentControllerState` — and the integration suite was already browsing exactly that. A server implementing Annex B could not claim Annex B. - **The published claim could go stale.** `SupportedFacets` was a snapshot taken during `RegisterAsync`, so a reference attached afterwards left it wrong. It is now bound through `BindRead` and recomputed on read, so the claim tracks the address space by construction rather than by discipline — which matters for anyone bolting Robot Intent onto an existing OPC 40010 node manager, where the attach ordering is often not theirs to choose. Two tests that **could not fail** were also replaced: one asserted `AccessLevel` equals `CurrentRead` to pin a read-only marking, but `BaseVariableState` initialises every variable to exactly that, so deleting the marking left it green; it is now a write expecting `BadNotWritable`, including a real OPC UA `Write` service call over a live session. Finally, a build break that a plain build hides: `RoboticsAotTests` used `out string?` in a project declaring `<Nullable>disable</Nullable>`. Building the project **without** `-f` suppresses `CS8632` through `NoWarn=nullable` and succeeds; building it **with** `-f net10.0` resolves `NoWarn` differently, `CS8632` fires, and `TreatWarningsAsErrors` makes it an error. CI builds per-TFM, so this would have failed there while passing every local build to that point. ## Testing and coverage | | | |---|---| | `dotnet build UA.slnx -t:Rebuild` | **0 errors, 2 warnings** — both pre-existing `CA1861` in `tests/Opc.Ua.Tools.Tests`, a file this PR does not touch | | **Whole `UA.slnx` test suite, net10.0** | **50 of 52 assemblies fully green** (measured at `40d9cf213`, before the `master` merge; the other two are explained below) | | `Opc.Ua.Robotics.Tests` | **467** net10.0, **447** net48 | | `Opc.Ua.Robotics.Intent.Tests` (live client <-> server) | **20** on net10.0 and net48, run repeatedly | | `Opc.Ua.OpenUsd.Tests` | **904** after merging `master` (664 before; the rest arrive with #4160 / #4162 / #4180) | | `Opc.Ua.Aot.Tests` | **121/121** | | `Opc.Ua.Di.Tests` (regression from the sample move) | **364/365**, one pre-existing skip | | **Changed-line coverage** | **90.7 %**, no file below 80 % — comfortably above the enforced band, which after #4158 applies only to patches larger than 100 changed lines | The two non-green assemblies are **not** caused by this branch. Rather than assert that, I ran the same selections at the merge-base `ae241b662` on the same machine: - `ServiceCallReassemblerTests.PrivateRequestSummaryFormatsKnownRequestKinds` expects `12.5` and gets `12,5` — a culture-sensitive assertion failing on a European locale. Fails 4/4 on **both** commits. - `CertRotationLiveTests.L2Cert2RotateCertificateDuringServerRestartRecoversSharedChannelAsync` fails on a teardown count. Fails 4/4 on **both** commits. - A third failure seen once, AOT `FindServersAsync` with `BadSecureChannelClosed`, did not reproduce: 4/4 on retest and 121/121 in the final run. Environmental. Two things are worth calling out because they would otherwise be invisible: - `tools/**` is **not** in the `coverage-thresholds.json` ignore list, and no test project referenced the OpenUSD tools assemblies — so their changed lines counted as uncovered and the real patch figure was 75 %, exactly the blocking threshold. Rather than widening the ignore list, the pure decisions in the viewport host (pointer-to-physical-pixel conversion, `RenderPickRequest` construction, stale-retry, backend discovery, pick-mode selection) were separated from the Avalonia/native shell and tested headless against a fake picking backend. - `dotnet build UA.slnx` **hides warnings on unchanged projects**; only `-t:Rebuild` surfaces them. That is how a `CA2263` introduced by a net48 portability fix survived several "zero warning" builds. The multi-target requirement earned its keep repeatedly: it caught a default interface implementation, `ArgumentNullException.ThrowIfNull`, `string.Create` with an interpolated handler, `ValueTask.FromResult`/`CompletedTask`, `Task.WaitAsync`, generic `Enum.GetValues` and generic `Enum.IsDefined`, and a non-generic `TaskCompletionSource` — none of which the net10.0 build complained about. A net10.0-**only** hang in the simulated executor and two load-sensitive flaky tests were also found and fixed at the cause. ### Merged with `master` `master` (through `e73e71184`) is merged in as `08205d81d`. Four conflicts, all where the two branches touched the same robot and OpenUSD surfaces, and none resolved by dropping a side: - #4162 added six files to `samples/MinimalRobotServer/` while this branch moved that directory to `samples/Robotics/MinimalRobotServer/`. They are kept at the moved path, and `UA.slnx` takes the union of both sides' new projects. - #4160 replaced `object` with a `UsdValue` union and rewrote `Flatten`; this branch had reformatted the same method and fixed a path in its doc comment. Git produced a hybrid that did not compile. The resolution keeps `master`'s `UsdValue` arm and `Flatten(UsdValue)` overload in this branch's block-bodied form, with the path fix retained. - `master` inserted `FindStageCamera` directly before two methods this branch had relocated, so the merge duplicated `WriteStageUsda` and `GetPrivateStateRoot`. Only `FindStageCamera` is genuinely new — `master`'s diff shows the other two as unmodified context — so the duplicates are dropped and this branch's `internal` versions kept, including the `GetPrivateStateRoot(string?)` overload the connector tests use to stay out of the real user profile. - `master` moved the OpenUSD stack to `0.4.0-alpha`; this branch pins `OpenUsd.Rendering` in the test project so the renderer-pick tests can reach the picking backend. Left at `0.1.0-alpha` that pin is below what the viewer now resolves transitively, which is `CS1705`. The pin follows `master`. CI was green on `baaf35e9` with **190 checks passing and none failing**, across every build leg (net472 / net48 / netstandard2.0 / netstandard2.1 / net8.0 / net9.0 / net10.0, Debug and Release) and the full test matrix on Windows and Linux. Since then `master` has been merged twice more and two CI-stability fixes landed (see below), so the current head is re-running. Locally, `dotnet build UA.slnx -t:Rebuild` gives **0 errors** and the 2 pre-existing `CA1861` warnings; Robotics **467** net10.0 / **447** net48, Robot Intent **20** on both, OpenUSD **904**, AOT **121/121**, source generation **3771**. ### Review round Five reviewers over disjoint areas found defects worth calling out, all fixed in `3ffec2c1`: - **A refused mission step was reported `Succeeded`.** The advance path returned the same `false` for "steps exhausted" and "step refused", so a protective stop between steps told a supervisory system the mission had completed while the robot stood halted with work unexecuted. - **Three attacker-controlled NodeIds reached the executor unvalidated** — `Pick.Tool`, `Place.Tool`, `ToolChange.DockStation`. `DockStation` drives a physical tool-exchange motion to a location the server never authorised. The replacement test enumerates NodeId members by reflection so the next one added cannot be missed. - **A lock-order inversion that loses a stop.** `CanCancel` and the mission condition evaluator ran under the host lock while the executor's own thread re-entered it via `ReportBlendBegin`. - **A non-terminal executor outcome killed the pump** from outside the `try/catch` that exists because the executor is untrusted — `Ready` stayed true and submissions kept being accepted while nothing moved. - **`Pause` published `Suspended` while the robot kept moving.** Now queue-only and honest about it; the specification gained the matching rule ([opcua-drafts `357a558`](https://github.com/marcschier/opcua-drafts/pull/47)). - **`RI-RealTimeChannel` and `RI-Safety` were false claims** — granted on an empty folder with no methods, and on the mere presence of a Mandatory node. - **The Part 10 promotions never promoted.** Namespace-1 BrowseNames declared second members beside the inherited ones; the conformance test could not see it because its lookup stripped the prefix. Fixed upstream and regenerated. - **Renderer picking never worked.** The reflective probe bound a renderer that is not a picking backend and throws off its owner thread. It now binds only `IRenderPickingBackend`, falls back immediately and loudly, and the docs say plainly that renderer picking is unavailable with this package version. - **The client lost command authority the instant it gained it** — monitored items report the current value first, and the lease treated every notification as a loss. ### CI stability fixes for master-side failures The CI split in #4158 turned on legs that had never run, and two of the failures they exposed were real bugs on `master` rather than anything this branch introduced. Both are fixed here because they were blocking every branch: - **ECC key generation was broken on macOS.** `ExportExplicitParameters` throws `PlatformNotSupportedException` there — Apple's SecurityTransforms supports named curves only — and it was called for exactly one value, the curve order `n`. The four curves OPC 10000-12 admits have published orders, so those are carried directly, with `CurveOrderTableMatchesThePlatform` checking each against the platform's own exported order wherever export works, so the constants cannot silently drift. This accounts for the two ECC failures in `test-macOS-latest-Server`. - **The certificate-leak detector raced asynchronous disposal.** It polled a fixed budget and reported whatever it saw, which cannot distinguish a genuine leak (count steady) from a suite still draining fire-and-forget disposals (count falling) — on a loaded agent that produced `Certificate leak detected: 2 instance(s)` with every test passing. It now waits for the count to **settle**, so a real leak is reported sooner than before while a slow drain gets as long as it keeps progressing. Shared by every suite that asserts no certificate leaks. The remaining macOS failures on `master` (`Gds`, `Tools`, `Redundancy.Samples`, `aot-macos`) have different root causes, are not reproducible without a macOS host, and are **not** addressed here. ### Merged with `master` again `master` through `416d619c4` (#4158, the CI matrix split and graduated coverage bands) is merged in as `08ae4528`. One conflict, in `docs/DeveloperGuide.md`, where both sides had deliberately rewritten the coverage-gate section: - `master`'s rewrite is kept in full — graduated `patch.bands`, Codecov being informational-only, and where the numbers surface per CI system. - This branch's paragraph about the `ignore` globs is kept too, re-sited ahead of those subsections. I re-checked it against the merged `coverage-thresholds.json` rather than assuming it still held: the list is still `tests/**`, `samples/**`, `obj`, `bin`, `*.g.cs`, with **`tools/**` absent** — so the warning that anything under `tools/` is measured like product code, and that an assembly no test project references contributes changed lines counted as *uncovered*, is still accurate and worth keeping. - `master`'s "reproduce a coverage failure locally" line supersedes this branch's near-identical one, so only `master`'s survives. Post-merge: `dotnet build UA.slnx -t:Rebuild` **0 errors**, 2 pre-existing `CA1861`; Robotics **467** net10.0 / **447** net48; Robot Intent **20** on both. ### Getting CI green The pipeline had never actually run on this branch until now (it was waiting on the fork-PR approval gate), so the first run surfaced four real problems, each fixed at source: - **Seven build legs failed** because `IntentEnabledRobot` pins `net10.0` for the OpenUSD payload but never opted into `RestrictForLegacyTfm`. On the legacy legs the libraries build as net472/net48, where `Opc.Ua.Types` exposes the `System.Threading.Lock` polyfill publicly, and that collides with the sample's own net10.0 BCL (`CS0433`). `Opc.Ua.OpenUsd.Connector.Viewer` was already using the opt-out for the same reason. - **A Linux-only test failure** turned out to be a real defect, not a platform quirk: `SetPose` published the *commanded* interpolated pose beside joint frames derived from the *solved* joints, so the two disagreed by the inverse-kinematics residual — about 8 mm, constant after any real motion. That is the lying-digital-twin defect one level deeper than the per-step IK fix reached. `SetPose` now derives both from the joint angles. - **Three source-generator tests** asserted the old emitted shape. The clause 6.2 Null-Variant fix was implemented in `ObjectTypeProxyGenerator` so every generated proxy benefits, which changed that shape; the tests are updated and strengthened to pin the `IsNull` branch as well. - **A CI-only timeout** in the simulated arm drain: the executor runs on a manual clock so the tests do not depend on machine speed, but the drain guarded itself with a wall-clock deadline, which put that dependence back. CI runs with coverage instrumentation, which is enough to take a per-step IK probe from ~0.6 s to over 5 s. The guard is now a simulated step budget. One failure was **not** from this PR and did not recur: a Roslyn `AccessViolationException` compiling `Opc.Ua.ISA95` on one leg, while the Debug leg of the same target passed on identical code and the Release build succeeds locally. ## Related Issues - Relates to #3827 — the request that prompted the robotics intent work. - Builds on #4127. The companion specification is drafted in the open at [marcschier/opcua-drafts#47](https://github.com/marcschier/opcua-drafts/pull/47) (`metaverse-specs/robot-intent/`), with the prior art and the reasoning behind each decision in the research document beside it. **Nothing in it is normative or endorsed by the OPC Foundation, and its NodeIds and namespace URI are provisional** — which is the main reason this is a draft. ## Checklist - [x] I have signed the [CLA](https://opcfoundation.org/license/cla/ContributorLicenseAgreementv1.0.pdf) and read the [CONTRIBUTING](https://github.com/OPCFoundation/UA-.NETStandard/blob/master/CONTRIBUTING.md) doc. - [x] I have added tests that prove my fix is effective or that my feature works and increased code coverage. - [x] I have added all necessary documentation. - [x] I have verified that my changes do not introduce (new) build or analyzer warnings. - [x] I ran **all** tests locally using the **UA.slnx** solution against at least .net **framework** and .net **10**, and all passed. - [ ] I fixed **all** failing and flaky tests in the CI pipelines and **all** CodeQL warnings. - [ ] I have addressed **all** PR feedback received. On the test checkbox, precisely: the whole `UA.slnx` suite now runs on net10.0 with **50 of 52 assemblies fully green**, and `Opc.Ua.Robotics.Tests` passes on **all five** target frameworks including net472, net8.0 and net9.0 which had never previously been exercised. The two remaining failures are reproduced identically at the merge-base and are detailed above, so I have ticked the box; if you would rather it stayed unticked until those two are green, say so and I will revert it. ## Points I would most like feedback on 1. **The namespace and NodeIds are provisional.** They come from a draft specification, not from the OPC Foundation. If this lands before the model is registered, the identifiers will move. 2. **The model lives in `Opc.Ua.Robotics`.** It is standalone on the base UA namespace and takes no dependency on OPC 40010, so a separate `Opc.Ua.RobotIntent` package would arguably be cleaner. Keeping it here was a deliberate call — this is where the robot-facing API already is — but it is the easiest thing to change now and the hardest later. 3. **Removing the convention API from #4127 is a breaking change** for anyone who adopted it. It was explicitly marked non-normative, so I have assumed that is acceptable — please say if a deprecation period is wanted instead. 4. **Serial execution** is a deliberate simplification. Concurrent `None`/`Soft` intents would be an optimisation, not a correction, but it is worth agreeing that reading. 5. **`samples/Robotics/` reorganisation** moves `MinimalRobotServer`. Happy to split that into its own commit if it makes review easier. --------- Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> Copilot-Session: 1dab1302-19c5-4a9b-a50c-d97d389713aa Copilot-Session: a248a589-9a20-4372-868e-5d347e57001b |

[WotCon] Track WoT Connectivity/Binding 1.1 and add projections (Section 12) (#4182)
Follow-up to #4128, which merged the WoT Connectivity 1.1 work against **draft2** of the companion specifications. Both drafts have moved since, and this branch tracks them through to **draft3**, adds the projection feature they introduced, and closes the gaps a bidirectional re-audit found. The specifications are the private [`OPCF-Members/spec-drafts`](https://github.com/OPCF-Members/spec-drafts) drafts of *OPC UA — WoT Connectivity 1.1* and *OPC UA — WoT Binding 1.1*. They are still drafts, which is why this is opened as a draft PR — see [Status](#status) at the bottom. ## What changed in the specifications Two revisions landed upstream while #4128 was in flight. **draft2** replaced the `eventGroup` / `actionGroup` grouping constructs with a single **projection / view** concept, added fifteen Section 6 vocabulary terms, and made two identifier rules normative. **draft3** ([spec PR #8](https://github.com/OPCF-Members/spec-drafts/pull/8)) un-deprecated the incorporated OPC 10100-1 v1.02 surface, restructured the conformance clause into three profiles, and tightened two security obligations. The draft3 NodeSet is **structurally identical** to draft2 — I diffed all 286 nodes node-by-node. Every change is metadata: 96 `ReleaseStatus="Deprecated"` attributes removed, `PublicationDate` advanced, and `WOTC-ProjectionMaterialization` claimed by three Type Nodes that previously implemented it in name only. ## Projections (WoT Binding Section 12) The substantial addition. A projection document selects affordances from other Thing Descriptions or Thing Models and resolves to a document of its own; materialized, it becomes an OPC UA `View` that **creates no affordance Node** and only `Organizes` what its sources already materialized. | Piece | Where | |---|---| | Document model and validation | `Opc.Ua.Types/Wot/WotProjection.cs`, `WotProjectionModel.cs` | | Four-stage resolution engine | `Opc.Ua.Types/Wot/WotProjectionResolver.cs` | | Materialization plan | `Opc.Ua.WotCon.Server/Materialization/WotViewProjectionPlan.cs`, `WotProjectionViewBuilder.cs` | | Live address-space host | `WotProjectionViewNodeManager.cs`, `LifecycleWotViewProjectionHost.cs`, `IWotViewProjectionHost.cs` | | Node lookup seam | `IWotMaterializedNodeIndex.cs` | Groups reached by `ua:Organizes` become organizational Objects rather than nested Views, only the outermost materialization is a `View`, and a member whose source is served by another server is omitted and reported rather than recreated — the federation case the clause calls out. ### How this is validated The specification publishes twenty worked examples, two of which are a **golden pair**: a projection document and the resolved view it is defined to produce. `WotSpecExampleTests` embeds all twenty and runs the pair through the resolver, asserting against *the specification's own expected output* rather than against my reading of the prose. That single document exercises all three selection forms, the bulk naming rule, the security closure naming and the provenance term. This is the strongest evidence in the PR, and it is worth more than the unit tests around it: it is the same check the upstream `validate_local.py` performs. ## Other spec work - **Section 6 vocabulary** — fifteen missing model and platform terms with their validation rules (`WotNodeSetConverter.ModelVocabulary.cs`). - **Portable identifiers** — the two rules release 1.1 made normative, with `WotNodeSetConverterOptions.AllowNonPortableIdentifiers` as a documented downgrade-to-warning switch for documents authored against v1.00. Defaults to `false`. - **xRegistry §6.9 identifier construction** (`XRegistryIdentifier.cs`) — reverse-authority symbolic identifiers; all seven published worked examples are test cases. ## Gaps found by re-auditing against draft3 I audited in both directions — every normative requirement to code, and every `uav:` term in code back to a spec that defines it. Three findings, all fixed: 1. **`Wot-Con 1.02` accepted anything well-formed.** draft3 makes format validation part of the unit, because *WoT-Con Minimal* is one unit wide and materialization projects a *valid* document. The 1.02 upload path only deserialized into the `ThingDescription` POCO, which happily accepts JSON that is not a WoT document at all — every member of that type is optional, so `{}` deserialized and was materialized. It now parses via `WotDocument.Parse` and requires the document to identify itself by a non-empty `name` or `title`, returning `Bad_DecodingError` and materializing nothing otherwise. The rule lives in `ThingDescriptionFormatValidator` and is shared with `CreateAssetForEndpoint`, whose auto-generated Thing Descriptions §11 also treats as untrusted input. 2. **Two `WoTFile` operations were ungated.** draft3 §11 names `Write` and `CloseAndUpdate` alongside the five management methods; both reached the materializer without an access check. `EnforceManagementAccess` is now wired into `WotAssetFileManager`. 3. **Two invented `uav:` terms.** `uav:NodeSet2Preservation` was declared and never used — removed. `uav:eventFields` is read by `OpcUaBindingPlanner` and defined in *neither* spec, while a comment claimed it came from OPC 10101. It still works for compatibility but is now documented as a non-standard extension at both sites rather than misattributed. The SSRF prohibition is satisfied by construction: there is no HTTP client anywhere in these assemblies, and all resolution goes through the injected `IWotThingResolver`. ## Two ambiguities fixed in the specifications themselves The audit turned up two places where a conforming implementer had to invent an answer. Rather than pick silently, I took both upstream — they are pushed to [spec-drafts PR #8](https://github.com/OPCF-Members/spec-drafts/pull/8) (all checks green) and are now normative in *Binding* §12.6 and *Connectivity* §7.13: - **`ViewVersion`** had one sentence saying only *that* it changes. It now changes iff the resolved membership changes, is updated at commit time alongside the `NodeVersion` stamping, and is a deterministic function of the membership alone in a canonical order — so two servers that resolved the same membership agree, which a per-server counter would not across a redundant pair. Explicitly **not monotonic**: compare for inequality only. - **"Type-level view"** was used once in §12.2 and defined nowhere, while every other statement of materialization was universal. §12.6 now *defines* it rather than contradicting §12.2: the NodeClass is `View` in both cases. Both were already what this code did, so neither changed behaviour — but the order-insensitivity the clause added was **not** covered by any test, and `ViewVersionIsUnchangedWhenOnlyTheOrderOfTheMembershipChanges` now holds it. It is mutation-verified: removing the ordinal sort turns it red. `docs/WotBindings.md` no longer lists these as points "the specification leaves open". ## Validation | Suite | Result | |---|---| | `Opc.Ua.Types.Tests` | 8525 ✅ (8518 on net48) | | `Opc.Ua.WotCon.Tests` | 1057 ✅ (net10.0 and net48) | | `Opc.Ua.WotCon.Bindings.Tests` | 559 ✅ | | `Opc.Ua.XRegistry.Tests` | 196 ✅ | | `Opc.Ua.Server.Tests` | 4027 ✅ | | `Opc.Ua.SourceGeneration.Core.Tests` | 3771 ✅ | | `Opc.Ua.WotCon.Samples.Tests` | 9 ✅ | The full `UA.slnx` builds with **0 errors and 0 warnings attributable to this PR** on all 6 TFMs (`TreatWarningsAsErrors` is on). `Opc.Ua.Server.Tests` and the source-generation suites are listed because this PR now also touches `MasterNodeManager` and the WoT-Con NodeSet. ## Compatibility No public API is removed or broken. Everything added is new surface using `ArrayOf<T>` / `ByteString` per the repo conventions, wired for DI with a direct-construction fallback, and the one behavioural tightening (`Wot-Con 1.02` format validation) rejects input that was never valid to begin with. One pre-existing issue is **not** addressed here because it came in with #4128 and is out of scope: `WotAssetFileManager.OnCloseAndUpdate` uses `.GetAwaiter().GetResult()`, which the repo rules ban. Worth a follow-up. ## Landed since this PR was opened - **DI upgraded to 1.05.0.** `ConnectsTo` was declared a subtype of `HierarchicalReferences`, contradicting OPC 10000-100 §5.5 Table 48. That is an upstream error in every official DI NodeSet up to 1.04, corrected by the OPC Foundation in 1.05.0, so the fixture is replaced with the verbatim 1.05.0 file rather than hand-patched. A guard test pins the corrected form. This also closed a second gap: six DI types the WoT model was missing are 1.05 additions. - **The sample Pump has the type definition OPC 40223 declares for it.** `Pump1.Identification` carried DI's `FunctionalGroupType` instead of `PumpIdentificationType`. Every test, the sample documents and the README agreed with each other about it, which is why it survived. - **`WotPumpAddressSpaceComparisonTests`** compares this server against `PumpDeviceIntegrationServer`, which builds the same OPC 40223 Pump from generated NodeSets and hand-written wiring. An independent oracle rather than a restatement of the same assumptions - it is what found the defect above. - **Error containment in `MaterializeProjectionViewsAsync`.** An exception mid-loop discarded the applied View handles before they were published, leaving View Nodes in the address space that nothing could remove. - **`HasWoTProjection`** is now created; it was documented and plumbed but never wired. - **The default in-memory View host** no longer deletes the View it has just applied. - **An undeclared NodeSet alias now says so.** It previously surfaced as `IdentifierMissing`, naming neither the value nor the fact that an alias was expected. - **`ViewVersion` follows the algorithm the specification now states.** My earlier spec text was rejected on review, correctly: it named neither the function nor the canonical order it demanded, ignored that OPC 10000-3 §5.4 requires a value greater than zero, and its "when, and only when" is unsatisfiable for a 32-bit value. §12.6 now specifies the algorithm outright and this implementation follows it exactly, pinned by an independently computed test vector. Implementing it surfaced a further defect in the clause - joining members on U+000A is not injective, because a NodeId string identifier may itself contain U+000A - which is fixed in the specification by length-prefixing each member. - **An auto-generated Thing Description is treated as untrusted input.** §11 requires it; `CreateAssetForEndpoint` validated the endpoint but handed whatever the discovery provider returned straight to the materializer. The `Wot-Con 1.02` format rule now gates both paths from one place. - **Document bytes moved out of the registry snapshot** into a content-addressed store, so a commit no longer rewrites the whole corpus to edit one document. Writes stage and are promoted during the commit, which preserves both durability-first ordering and the fail-closed rule that a blob directory without a manifest means operator recovery. Restoring streaming digest verification along the way closed a real gap: content integrity had degenerated to a length comparison. - **External references now reach a NodeManager registered later.** A reference to a Node that does not exist yet is dropped rather than queued, and the dynamic-registration path had no second phase to apply them in, so registering a NodeSet before the one it points into lost the forward edge permanently. Review of that change then found a state leak in its rollback path, fixed with a red-to-green regression test. - **`WOTC-Legacy` is renamed `Wot-Con 1.02`** in the specification and here. Editorial: the NodeSet diff is `<Category>` values only. ## Status Open for review. Two things may still move: 1. **The specifications are unpublished drafts.** Anything here can change if the working group decides differently. The `ViewVersion` definition has since been settled - §12.6 specifies the algorithm and this follows it - but the same could happen to any other clause tracked here. 2. **`uav:eventFields`** is kept as a documented non-standard extension. That is a judgement call the WG may want to reverse, either by adopting the term or removing it. Two known items are recorded rather than fixed: - `Pump1` has no hierarchical parent, so it is reachable by NodeId but not by browsing down from `Objects`. The cross-NodeSet ordering defect this was originally attributed to is fixed above, and cross-manager references are now symmetric in both registration orders. The Pump itself is still blocked on a different cause found while verifying that fix: with the reference added, `DeviceSet` exists but the Pump has **zero** inverse references, so the edge is dropped at *import* - before any external-reference machinery runs. That is a separate defect in the materialization path, not the one that was fixed, and it is left recorded rather than guessed at. - `WotAssetFileManager.OnCloseAndUpdate` uses `.GetAwaiter().GetResult()`, which the repo rules ban. Pre-existing from #4128 and out of scope here. Review of the projection resolver and the materialization host is the most valuable thing to look at; the vocabulary and identifier commits are mechanical by comparison. --------- Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> Copilot-Session: 9e6a5abf-3299-4cd1-9855-010fedbf0ad8 |

[WotCon] Add OPC UA WoT Connectivity 1.1 with the Types, source generation, Server and xRegistry work it builds on (#4128)
## Summary Adds OPC UA WoT Connectivity 1.1 to the stack, together with the Types, source generation, Server and xRegistry work it is built on. This branch is the merge point for the fourteen-PR stack that replaced integration PR #4093; every constituent PR was reviewed and approved separately and is listed below. 414 files changed, +108,936 / -3,199. Roughly 46k added lines of product code, 57k of tests, plus samples, tools and documentation. ## Types - Complete `ExtensionObject` raw-body decoding for binary, XML and JSON bodies by resolving the concrete type through the message context's encodeable factory, and simplify the `Variant` structure helpers by delegating to it (#4128). - Add `IAtomicFileReplace` as an optional `IFileSystem` capability so existing external implementations keep working, with atomic publish for `LocalFileSystem` via `File.Replace`/`File.Move` and for `VirtualFileSystem` by re-keying the in-memory entry (#4128). - Add lossless conversion between WoT documents and NodeSet2 (`Opc.Ua.Wot.WotNodeSetConverter`). A byte-exact `uav:nodeSet` envelope is preserved when requested, the structured `uav:nodes` projection is used when the readable vocabulary is incomplete, and NodeSet2 is otherwise synthesized from readable WoT terms. Unmapped JSON members survive a round trip as pointer-addressed residue (#4131). ## Source generation - Improve the NodeSet to ModelDesign conversion and the generated node state (#4132). - Generate OPC UA models directly from WoT Thing Description files (#4134). ## Server - Add live NodeManager shadow and immediate reload. A reload materializes a new generation beside the active one and switches atomically; the superseded generation is retired gracefully so existing MonitoredItems keep being served until they drain, or immediately when the caller asks for it. Includes the request admission and drain machinery that lets an orderly shutdown wait for admitted requests instead of tearing down underneath them (#4147). - Make subscription transfer between sessions transactional, so a failed transfer leaves neither session holding a partially moved subscription (#4150). ## xRegistry - Allow clients to use explicit registry roots rather than assuming a well-known location (#4130). ## WoT Connectivity - Add the WoT Connectivity 1.1 information model: a registry-first revision layered on the abstract xRegistry base model, incorporating the complete published OPC 10100-1 v1.02 surface as deprecated nodes in the same namespace so existing 1.02 clients keep working (#4139). - Add the protocol binding abstractions and planners that compile WoT forms into executable plans (#4140). - Add the HTTP, Modbus, OPC UA and MQTT binding executors (#4144). - Add the registry and its stores, including document versioning, validation, dependency resolution and refresh (#4146). - Add the registry client (#4142). - Materialize WoT Thing Descriptions into the server address space, deriving types from Thing Models and instances from Thing Descriptions (#4154). - Restore the WoT asset registry bridge so the deprecated 1.02 asset surface is backed by the registry (#4171). - Add the WoT Connectivity samples and complete the documentation (#4156), and restore the remaining coverage and docs (#4172). ## New projects `src/Opc.Ua.WotCon.Bindings`, `src/Opc.Ua.WotCon.Bindings.Mqtt`, `tests/Opc.Ua.WotCon.Bindings.Tests`, `tests/Opc.Ua.WotCon.Samples.Tests`, and the `samples/WotCon` AggregationServer, AggregationClient and FlatTagServer samples. ## Constituent pull requests Merged into this branch top-down, each independently approved: | PR | Title | | --- | --- | | #4128 | [Types] Complete ExtensionObject decoding and add an atomic file replace capability | | #4131 | [Types] Add lossless conversion between WoT documents and NodeSet2 | | #4132 | [SourceGeneration] Improve NodeSet to ModelDesign conversion and generated node state | | #4134 | [SourceGeneration] Generate OPC UA models from WoT Thing Description files | | #4147 | [Server] Add live NodeManager shadow and immediate reload | | #4150 | [Server] Make subscription transfer between sessions transactional | | #4130 | [XRegistry] Allow clients to use explicit registry roots | | #4139 | [WotCon] Add the WoT Connectivity 1.1 information model | | #4140 | [WotCon] Add the WoT protocol binding abstractions and planners | | #4144 | [WotCon] Add the HTTP, Modbus, OPC UA and MQTT binding executors | | #4146 | [WotCon] Add the WoT Connectivity registry and its stores | | #4142 | [WotCon] Add the WoT Connectivity registry client | | #4154 | [WotCon] Materialize WoT Thing Descriptions into the server address space | | #4156 | [WotCon] Add the WoT Connectivity samples and complete the documentation | | #4171 | Restore WoT asset registry bridge | | #4172 | Restore WoT coverage and docs | Supersedes #4093. ## Follow-up The WoT Connectivity and WoT Binding drafts have moved to 1.1-draft2 since this work was authored. Aligning with that revision - the removed group vocabulary, the new projection/View construct, the remaining model vocabulary terms and the two new portable-identity validation rules - is tracked separately and will follow in its own pull request. ## Validation Built for every target framework with zero warnings and zero errors, and validated at the tip of the stack with `Opc.Ua.WotCon.Tests` at 999 passed / 0 failed and `Opc.Ua.Server.Tests` at 4024 passed / 0 failed. --------- Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> Copilot-Session: 9e6a5abf-3299-4cd1-9855-010fedbf0ad8 |

Make NodeId assignment during a node copy explicit (#4157)
Fixes #4137. ## The problem `NodeState.Initialize(ISystemContext, NodeState)` copies a node. Every child it materialises through `CreateChild` gets a per-instance NodeId from `ISystemContext.NodeIdFactory`, and is then initialised from its source on the very next statement - which overwrites that NodeId. The assignment is therefore *always* discarded: it only burns identifiers, and permanently leaks them for factories that track outstanding allocations. Booting the Robotics node manager left ten reservations behind that every later allocation skipped. #4123 fixed the symptom by hiding the factory for the duration of the copy, wrapping the context in one that reports `NodeIdFactory` as `null`. The review objection was fair: a context that lies about one property is hard to reason about, and it only works because that property is allowed to be null. ## What this does States the intent instead of faking the environment. NodeId assignment is now an argument of the two members that materialise children: ```csharp public virtual BaseInstanceState? CreateChild( ISystemContext context, QualifiedName browseName, bool assignInstanceNodeIds = true); protected virtual BaseInstanceState? FindChild( ISystemContext context, QualifiedName browseName, bool createOrReplace, BaseInstanceState? replacement, bool assignInstanceNodeIds = true); ``` A copy passes `assignInstanceNodeIds: false` and every node type - generated or hand-written - sees the real context. There is no capability property, no wrapper, and no second overload to keep in sync. `MethodState`, `BaseDataVariableState` and the source generator template each collapse to a single `FindChild` override that threads the argument into its `CreateOrReplace<Child>` helpers. ## Breaking change The four argument `FindChild` and the two argument `CreateChild` virtuals are gone. - **Call sites are unaffected.** The new parameter defaults to `true`, so `CreateChild(context, browseName)` and `FindChild(context, browseName, true, null)` keep compiling and keep the 1.5.378 behaviour. - **Overrides must add the parameter.** A node manager that overrides either member gets `CS0115` until it does. The compiler points at every site; `docs/migrate/2.0.x/node-states.md` shows the before/after. This is deliberate, per review: the stack ships all base types, and types generated from a model are regenerated for 2.0 anyway. ## Also fixed `MethodState.FindChild` returned `OutputArguments` when asked for `InputArguments` with `createOrReplace: false` - a pre-existing bug in the method being restructured. Covered by `FindChildReturnsTheRequestedArgumentsProperty`. ## Validation - Full `dotnet build UA.slnx`: **0 errors, 0 warnings**. - `Opc.Ua.Types.Tests`, `Opc.Ua.SourceGeneration.Core.Tests`, `Opc.Ua.SourceGeneration.Tests`, `Opc.Ua.Di.Tests`, `Opc.Ua.Robotics.Tests` - all passing. - Each new regression test was checked to fail without its corresponding fix. --------- Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> Co-authored-by: Copilot Autofix powered by AI <175728472+Copilot@users.noreply.github.com> Copilot-Session: 8cbb8cd0-f0cb-4ab0-bea2-6202fbf69485 Copilot-Session: f45109d9-59cb-4ffd-a4f7-16e1ea449ae4 |

Source generator: typed NodeSet method signatures and referenced model accessors (#4124)
**Stack 2/5** — base #4123. Part of the #4096 split; see #4096 for the overall picture. > Review after #4123. The diff shown against `master` will include #4123 until that merges. ## What this is Source generator only; no runtime library changes. ## Contents - **Typed NodeSet method signatures.** A method imported from a NodeSet now gets a typed signature. Methods that share a declared signature are grouped onto one generated `MethodType`, named after its owner when the plain name would collide, so two unrelated `Execute` methods no longer share a class. - **An override that keeps the signature it inherits keeps the declaration it overrides.** Pointing `MethodDeclarationNode` at the override itself made `MethodDeclarationId` self-referential. OPC 10000-4 lets a caller invoke a method with the NodeId of its declaration in the ObjectType *or any supertype*, and `MethodState.MethodDeclarationId` is what the server matches on, so `Call` stopped resolving and returned `Bad_MethodInvalid` for every alarm subtype. An override that genuinely changes its signature still becomes its own declaration. - **`StateNumbers` / `TransitionNumbers` were emitted empty for every NodeSet-sourced model**, because such children arrive as `VariableDesign` rather than `PropertyDesign` and were filtered out. Any companion model built from a NodeSet was writing `StateNumber = 0` on the wire — a Part 16 defect well beyond the models in this stack. The ModelDesign path is unchanged. - **Referenced models can contribute fluent accessors**, carried by a model dependency payload so a downstream model can extend an upstream one. ## Notes for the reviewer - `tests/Opc.Ua.SourceGeneration.Tests` is left at its `master` content here. Its new vendor-subtype test uses the Robotics NodeSet as its fixture, so it can only land with the Robotics change at the top of the stack (5/5). - `PumpInstanceNodeIdRegressionTests` gains six `InputArguments`/`OutputArguments` entries for argument-less standard condition methods. Typed method signatures materialise those properties from the `ConditionType` declaration even where the method takes none. That is a real deviation, pinned rather than hidden so it stays visible; it is worth a follow-up. ## Validation `dotnet build UA.slnx` — 0 errors. | Suite | Result | | --- | --- | | Opc.Ua.SourceGeneration.Core.Tests | 3739 / 0 | | Opc.Ua.SourceGeneration.Tests | 81 / 0 | | Opc.Ua.Di.Tests | 304 / 0 | | Opc.Ua.History.Tests | 506 / 0 | | Opc.Ua.Gds.Tests | 1095 / 0 | History and GDS are listed because they are what the method-declaration fix above is load-bearing for: without it they fail with 10 and 370 errors respectively. --------- Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> Copilot-Session: 8cbb8cd0-f0cb-4ab0-bea2-6202fbf69485 |

Assign instance NodeIds in generated CreateOrReplace<Child> helpers (#4104)
# Description
The model source generator emits two families of instance helpers with
inconsistent NodeId behaviour:
* `ISystemContext.CreateInstanceOf<Type>(parent, browseName)` rebases
the whole materialised subtree onto per-instance NodeIds.
* `<Owner>.CreateOrReplace<Child>(context, replacement)` — the plumbing
behind `NodeState.CreateChild` / `ReplaceChild` — did not. The child it
produced was either bare (null NodeId, no browse name) or kept the
type-level NodeId of the replacement.
Any node manager mixing the two had to hand-roll a recursive re-stamp
before registration, or sibling instances collided on NodeIds — a
failure that only surfaces at registration time.
`samples/PumpDeviceIntegrationServer` did exactly this.
## What changed
**Generator** (`tools/Opc.Ua.SourceGeneration.Core`)
* `CreateOrReplace<Child>` gains `bool assignInstanceNodeIds = true`.
When enabled and the context supplies an `ISystemContext.NodeIdFactory`,
a child whose NodeId is null or still equal to its declaration NodeId —
and its descendants — are rebased through
`NodeInstanceExtensions.AssignInstanceNodeId` /
`AssignInstanceChildNodeIds`, with the owner as reference root. **A
NodeId the caller already assigned is never overwritten.**
* The helper also stamps the new child's `SymbolicName` / `BrowseName` /
`DisplayName`. Without an identity, a path-based `INodeIdFactory`
derives `{parent}_` for *every* child of a parent, so the assignment
would have introduced collisions rather than removed them. `BrowseName`
stamping is guarded on `context.NamespaceUris != null` — event-reporting
paths pass a context without a namespace table.
* All generated `Create*` factory call sites pass
`assignInstanceNodeIds: false`: they build declaration subtrees whose
NodeIds must stay at their type-level values, and the enclosing
`CreateInstanceOf<Type>` factory rebases the finished subtree in a
single pass.
* The `CreateInstanceOf<Type>` rebase guard drops the `parent != null`
requirement — supplying a `browseName` is what marks a dynamically
materialised instance. Calling it without one (as the generated
`NodeStateActivator`s do, and when replacing a well-known singleton)
still keeps the declaration NodeIds.
* `replacement` is now emitted as `BaseInstanceState?` on
`CreateOrReplace<Child>` and on the generated `FindChild` override,
matching the documented contract and the base `NodeState.FindChild`
signature.
**Hand-written twins** —
`MethodState.CreateOrReplace{Input,Output}Arguments` and
`BaseDataVariableState.CreateOrReplaceEnumStrings` gain the same
parameter and behaviour, sharing a new internal
`NodeInstanceExtensions.AssignNewChildInstanceNodeIds`. This is also
required so the generated `public new` overrides keep hiding a matching
base signature (otherwise `CS0109` with `TreatWarningsAsErrors`).
**Sample** — `PumpDeviceIntegrationServer` now passes the real
`DeviceSet` parent to the factory and drops `AssignChildNodeIds` plus
the manual root stamp.
**Docs** — new *"Materialising instances at runtime — NodeId
assignment"* section in `SourceGeneratedNodeManagers.md` and a refreshed
`DeviceIntegration.md`.
## Design note: why not the guard proposed in the issue
Gating on *"the owner already has an instance NodeId"* cannot be
implemented as `owner.NodeId != <ownerTypeNodeId>`. The generated child
factories call `<Owner>.CreateOrReplace<Child>` on **declaration**
instances — `CreatePumpType_Operational` runs on a
`FunctionalGroupState` whose NodeId is `ObjectIds.PumpType_Operational`,
not `ObjectTypeIds.FunctionalGroupType` — so the comparison would be
true while the *type template* is being materialised (`forInstance:
false`) and would rewrite the address space's declaration NodeIds. The
explicit opt-out separates the two callers unambiguously.
## Compatibility
Adding an optional parameter is source-compatible. Behaviour changes for
callers of `NodeState.CreateChild` / `ReplaceChild` when the context
carries a `NodeIdFactory`: the new child now carries a browse name and a
per-instance NodeId instead of nothing.

### Tests added
**Generator emission** (`NodeManagerGeneratorTests`) —
`CreateOrReplaceChildAssignsInstanceNodeIdsByDefault`,
`TypeFactoriesOptOutOfCreateOrReplaceNodeIdAssignment`,
`CreateInstanceOfFactoriesRebaseWithoutAnExplicitParent`.
**Helper behaviour** (`NodeInstanceExtensionsTests`) —
`CreateOrReplaceArgumentsAssignsInstanceNodeIds`,
`CreateOrReplaceArgumentsKeepsCallerAssignedNodeId`,
`CreateOrReplaceArgumentsHonoursTheAssignmentOptOut`,
`CreateOrReplaceEnumStringsAssignsInstanceNodeIds`.
**Pump DI server regression** (`PumpInstanceNodeIdRegressionTests`,
added on review feedback):
| Test | Asserts |
| --- | --- |
| `ConfiguredPumpExposesTheFullModelSurface` | The exact set of **77
model identifiers** a configured pump materialises. |
| `EveryPumpInstanceExposesTheSameGeneratedModelSurface` | A second pump
exposes the identical generated surface, minus what the fluent
`Configure` pass adds. |
| `MaterialisedPumpNodeIdsComeFromTheNodeIdFactory` | Every NodeId is
`{parentIdentifier}_{symbolicName}` in the parent's namespace — minted
by `PumpNodeManager.New`. |
| `MaterialisedPumpNodeIdsAreUniqueAcrossInstances` | No NodeId is null
or shared between two instances of the type. |
| `GeneratedFactoryAssignsInstanceNodeIdsBeforeRegistration` | The
factory output already carries per-instance NodeIds before
`AddPredefinedNodeAsync` applies its defensive rebase. |
| `AlarmSubtreeKeepsStandardDeclarationNodeIds` | Pins the alarm
subtree's standard-namespace ids — a pre-existing gap outside the
generated helpers. |
The 77-identifier baseline was captured by running the same subtree walk
against the pre-change commit and diffing it against the post-change
run: **identical** — same node set, same NodeIds.
### Local test runs
| Suite | net10.0 | net48 | net472 |
| --- | --- | --- | --- |
| `Opc.Ua.SourceGeneration.Core.Tests` | 3722 passed | 3721 passed | — |
| `Opc.Ua.SourceGeneration.Tests` | 81 passed | 81 passed | — |
| `Opc.Ua.SourceGeneration.Stack.Tests` | 90 passed | — | — |
| `Opc.Ua.Types.Tests` | 8083 passed | 8076 passed | — |
| `Opc.Ua.Di.Tests` | 303 passed | 303 passed | 277 passed |
| `Opc.Ua.Core.Tests` | 4134 passed | — | — |
| `Opc.Ua.Gds.Tests` | 1095 passed | — | — |
| `Opc.Ua.History.Tests` | 506 passed | — | — |
| `Opc.Ua.Server.Tests` | 3626 passed, 1 failed | 3574 passed, 1 failed
| — |
The single `Opc.Ua.Server.Tests` failure —
`ServerFluentApiHostingTests.ConfigureApplicationBuildsSharedClientAndServerConfigurationAsync`
— is pre-existing and unrelated; it reproduces on a stashed clean
`master` tree.
> [!NOTE]
> The source-generation test harness compiles generated model code
against a hand-written `Opc.Ua` API stub
(`tests/Opc.Ua.SourceGeneration.Core.Tests/CompilerUtils.cs`, shared by
three test projects). Its 73 `CreateOrReplace<Child>` declarations were
updated to the new signature — without that, every generated call site
passing `assignInstanceNodeIds: false` failed to bind.
`NodesetMethodArgumentTests` pinned the exact emitted call and was
updated to the new one for the same reason as the
`NodeStateGeneratorTests` expectations.
> [!NOTE]
> `master` has been merged into this branch. The only conflict was in
`NodeStateGeneratorTests.cs`, where master rewrapped the expected
call-site strings while this branch appended `assignInstanceNodeIds:
false` to them — kept master's wrapping and re-applied the argument.
Master's two new templates (`Create_MethodArguments`,
`Assign_MethodArgumentValues`) call
`CreateOrReplace{Input,Output}Arguments` while building a declaration
subtree, so they now pass `assignInstanceNodeIds: false` to preserve
their stated intent of leaving the property node's identity untouched.
> [!TIP]
> Changing a source generator leaves dependent projects' cached
generated output stale. If a local build reports `CS1739: ... does not
have a parameter named 'assignInstanceNodeIds'` or `CS0109` on a
generated `CreateOrReplace*`, run `dotnet build <project> -t:Rebuild`.
Clean CI builds are unaffected.

Add OPC UA ISA-95 Common Model and Job Control support (#4089)
# Description Adds first-class support for the OPC UA ISA-95 companion specifications: - OPC-10030 Common Model. - OPC-10031-4 Job Control V1. - OPC-10031-4 Job Control V2. The change introduces `Opc.Ua.ISA95`, `Opc.Ua.ISA95.Client`, and `Opc.Ua.ISA95.Server`, together with a NativeAOT-compatible minimal server sample and comprehensive tests. ## Highlights - Compiles the three canonical NodeSets and identifier mapping CSV files through the source generator. - Adds NodeSet identifier mapping validation, typed method arguments/results, companion event records, and generated method argument nodes. - Provides typed Common Model builders with normative relationships and an injectable `GeoSpatialLocationType` provider. - Implements lossless V1/V2 Job Control providers over a shared version-neutral store, including state paths, status events, comments, response queries, catalog changes, and cohesive DI registration. - Adds subtype-aware typed clients, standalone encodeable registration, `IIsa95ClientFactory`, and V2 status-event streaming. - Adds the `MinimalIsa95Server` sample, package documentation, and an ISA-95 guide with conformance and HA guidance. - Tracks typed RSL/GPOS integration as follow-up issue #4095. ## Validation - `Opc.Ua.ISA95.Tests`: 137/137 passed on `net10.0` and `net48`. - Source-generator suites: 81/81 model, 90/90 stack, 3718 passed / 8 skipped core. - `EventRecordFieldReaders` feedback tests: 6/6 on `net10.0` and `net48`. - `EventRecordFieldReaders` changed-method patch coverage: 100% line coverage (36/36) and 100% branch coverage (22/22). - `Opc.Ua.ISA95`, `.Client`, and `.Server` build across all configured target frameworks without new diagnostics. - Cobertura line coverage: 88.08% model, 90.04% client, 91.19% server. - NativeAOT sample publishes and passes a live typed V2 Store/status-event validation. - The ISA-95 NativeAOT smoke test passes in the source-generated native test executable. - OPC UA KB NodeSet validation reports zero errors for Common, V1, and V2. The broader NativeAOT executable still reports unrelated existing GDS and complex-type test failures; the ISA-95-specific native test passes. ## Node state generator fixes Generating method arguments inline for imported nodesets regressed every model that already emits `InputArguments` / `OutputArguments` child node factories: - The inline block ran before the child factories. `MethodState.CreateOrReplaceInputArguments` keeps the property that was assigned first, so the child carrying the well-known NodeId was dropped and a NodeId-less placeholder remained in the address space. This broke browsing (reference descriptions without a target) and made method arguments unreachable at their well-known NodeIds. - The `MethodDeclarationId` fallback keyed on an autogenerated display name redirected every declared method of the standard address space to its own NodeId, which made method calls fail. The inline block is now emitted after the child factories and reduced to a value assignment when a child factory exists. The value is only re-emitted when an argument references a namespace other than OPC UA, because the value of an imported property is the verbatim XML of the source nodeset whose namespace indices do not survive the import. The `MethodDeclarationId` fallback is restricted to declarations without a resolvable NodeId. The generated OPC UA address space is byte-identical to `master` again. ## Related Issues - Fixes #4088 - Follow-up: #4095 |

Add generic xRegistry libraries (abstract registry base model) (#4097)
# Description xRegistry is the *abstract registry base model*: a registry-agnostic, content-addressed resource registry. It knows nothing about what a resource contains — a concrete registry supplies its own companion namespace and a fingerprinting strategy and reuses everything else. The PubSub Schema Registry in #4007 is the first specialization (its resources are schema documents), and #4093 (WoT Binding) carries a byte-identical copy of the same base NodeSet, so a shared canonical home is worth having. ## Packages | Package | Depends on | Contains | | --- | --- | --- | | `OPCFoundation.NetStandard.Opc.Ua.XRegistry` | `Opc.Ua.Core` | Abstract base companion model (compiled by the model source generator), `XRegistryWellKnown`, `IResourceContentIdProvider` | | `OPCFoundation.NetStandard.Opc.Ua.XRegistry.Client` | + `Opc.Ua.Client` | `XRegistryClient` (abstract) / `GenericXRegistryClient` (sealed), built on the generated ObjectType proxies | | `OPCFoundation.NetStandard.Opc.Ua.XRegistry.Server` | + `Opc.Ua.Server` | Fast-path / registration / federation node managers, `XRegistryServerOptions`, `IXRegistryResourceStore` | `Opc.Ua.XRegistry` deliberately depends on neither SDK, so a codec or a shared contracts assembly can reference the identity abstraction without pulling in the client or the server. ## The model is compiled, not loaded The companion model is compiled into the assemblies by the OPC UA model source generator. `Opc.Ua.XRegistry.NodeSet2.xml` is an `AdditionalFiles` generator input only — there is no `EmbeddedResource`, no runtime NodeSet parsing and no hand-written NodeId tables for anything the model declares. All three node managers load it the same way: ```csharp protected override NodeStateCollection LoadPredefinedNodes(ISystemContext context) { return new NodeStateCollection().AddOpcUaXRegistry(context); } ``` `XRegistryWellKnown` is reduced to the namespace URI plus the identifiers of the *instances* a registry materializes at runtime, which live above the model's own 63000-63999 range so they can never collide with it. ## What it does - **Content-derived identity** — `IResourceContentIdProvider` maps a document + format to a fingerprint and names the (canonicalization, hash) algorithm. Identity is derived from the bytes, not assigned by the server, so it is stable across registries — which is what makes de-duplication and federation work. - **Opaque-NodeId fast path** — a registered resource is reachable at an Opaque `NodeId` whose Identifier is the raw content-id bytes, so a consumer that received the id on the wire resolves the document in a single `Read`: no Browse, no fingerprint recomputation. The client reads it through the `ReadBytesAsync` session extension, so a document larger than `MaxByteStringLength` is fetched with range-based reads rather than failing. Optionally pre-publishes a seed resource so a fresh server can resolve one resource before any registration. - **The model's own lifecycle** — the registry root is a `RegistryType` instance serving `CreateGroup` / `GetOrCreateGroup`; each group serves `CreateResource` / `GetOrCreateResource`; and because `ResourceType : FileType`, the document *is* the file — content is streamed through the inherited `Open` / `Read` / `Write` / `Close`. `Close` fingerprints the accumulated bytes and publishes the Opaque fast-path node at runtime. Identical bytes reuse the existing node, whose lifetime is reference counted so it survives until the last resource resolving to those bytes is gone and is retired when a resource is re-written with different content. - **Optimistic concurrency** — `Delete(ExpectedEpoch)` on both resources and groups, and the same epoch check on label mutations, so a caller working from a stale read is rejected rather than clobbering a concurrent change. - **Labels** — `RegistryType`, `GroupType` and `ResourceType` each expose an `AttributesType` Object with `AddAttribute` / `RemoveAttribute`; labels are published as addressable `String` Properties. - **Federation** — a resource hosted by another registry is published as a real `ResourceType` instance whose `ExternalReference` (`ExpandedNodeId` + `ServerIndex` into the local `ServerArray`) and `ResourceUrl` carry the link and whose `Xid` carries the content-id. Because it is an ordinary `ResourceType`, a generic client drives a federated resource through exactly the same proxy as a local one. ## Extensibility A domain registry subtypes the base model — the PubSub Schema Registry declares `SchemaFileType : ResourceType` — and the generator mirrors that hierarchy across assemblies, so the proxy chain follows automatically (`SchemaFileTypeClient : ResourceTypeClient : FileTypeClient`). ```text abstract XRegistryClient ├── sealed GenericXRegistryClient // any registry namespace ├── SchemaRegistryClient (domain) └── WotRegistryClient (domain) ``` * A **domain client** derives from `XRegistryClient` and inherits the whole lifecycle. Helpers written as extension methods over a base proxy (such as `WriteDocumentAsync` on `ResourceTypeClient`) are callable on the domain proxy with no inheritance in the client layer. * A **generic client** still drives a domain registry, because a domain instance *is* an instance of the base type. This is covered by a test that defines a domain subclass over the base. ## State Document bytes live behind an injectable `IXRegistryResourceStore`. Because a resource is a `ResourceType`, which *is* a `FileType`, the store mirrors the file access model: reads and writes are **offset and length based**, so a document never has to be materialized as a whole and a ranged read touches only the bytes it needs. The document is transferred with the inherited `FileType` Methods, whose mode bits are honoured: a write that does not set `EraseExisting` starts from the stored bytes and replaces only the range it writes rather than truncating the rest. A handle is valid only on the resource and the session that opened it, and a session's handles are released when it closes. Two implementations ship: `InMemoryResourceStore` (the default, in-process) and `FileSystemResourceStore`, built on the `IFileSystem` abstraction so documents outlive the process and a shared volume can back a cluster. `XRegistryResourceStoreContractTests` is a reusable fixture that validates any implementation against the contract. ## Transport security Registry **writes always require a `SignAndEncrypt` secure channel** — a document and its content-derived identity are integrity-critical, so every mutation is rejected with `BadSecurityModeInsufficient` on a channel that is only signed or unprotected. This is not configurable. Reads are allowed on any secure channel by default; `RequireEncryptionForReads` extends the requirement to them when the documents themselves are confidential. An in-process call carries no channel and is always allowed. ## Hardening The lifecycle Methods are remotely callable, so every unbounded dimension is bounded via `XRegistryServerOptions`; exceeding a bound fails the call rather than the server: | Option | Default | Enforced on | Status code | | --- | --- | --- | --- | | `MaxConcurrentUploads` | 64 | `CreateResource`, `Open` | `BadTooManyOperations` | | `MaxResourceBytes` | 16 MiB | `Write` | `BadRequestTooLarge` | | `MaxRegisteredResources` | 4096 | `CreateResource` | `BadTooManyOperations` | ## A source generator bug fixed along the way Building on the compiled model surfaced a defect in shared generator infrastructure. `NodeSetToModelDesign.CreateDecoder` decoded values with an empty `EncodeableFactory`, so a NodeSet2's method `InputArguments` / `OutputArguments` — encoded as a list of `Argument` ExtensionObjects — never decoded, while `HasArguments` was still set. **Every** NodeSet2-sourced model in the stack was silently generating argument-less `MethodState`s and ObjectType proxies. ModelDesign-sourced models (the core stack) were unaffected, which is why this went unnoticed. Fixed in `b87726af` with a regression test that fails without it. Two defects in the xRegistry NodeSet itself were fixed at the same time: `BrowseName="1:InputArguments"` → ns-0 `InputArguments` (published NodeSets never namespace-qualify these), and the `CreateResource` / `GetOrCreateResource` **output** `VersionId` renamed to `AssignedVersionId`, which collided with the input of the same name and produced a duplicate C# parameter. ## Other fixes applied while extracting - `XRegistryRegistrationNodeManager` uses `System.Threading.Lock` instead of an `object`-typed sync root, per the repository locking rules. - Dropped the `InternalsVisibleTo` entries granting internals to `Opc.Ua.PubSub.Server.Tests`. That project only consumes public `XRegistryWellKnown` API. - The `UA.slnx` edit in #4007 accidentally **replaced** the `tests/Opc.Ua.Redundancy.Kubernetes.Tests` entry instead of adding a line, silently dropping that project from the solution. The entry is preserved here and the change is purely additive. ## Tests `tests/Opc.Ua.XRegistry.Tests` (168) covers the group and resource lifecycles, the `FileType` transfer, delete and epoch conflicts, labels, federation, both resource stores, the fast path, transport security and the extensibility contract — positive and negative paths. Passing on `net10.0` and `net48`. Patch line coverage is **98.5%**. Also adds `tests/Directory.Build.props` / `.targets`: the .NET 10 SDK prunes `Microsoft.Extensions.Logging.Abstractions` out of the test output, and coverlet's Mono.Cecil resolver only searches the output directory, so it silently fails to instrument every module that references `ILogger` and reports 0% coverage for them. These force the package back into the restore graph and copy its implementation next to the test binary. ## Documentation New [`docs/XRegistry.md`](docs/XRegistry.md), linked from the documentation index. |

Source generator: support compiled companion models and safe NodeState writes (#4063)
## Summary Combines the compiled companion-model support from #4062 with the NodeState emission fixes already in this PR. The model source generator can now consume compiled companion `NodeSet2` models more reliably, while generated factories consistently target base `NodeState` members even when a generated subclass shadows them. ## Changes ### Compiled companion NodeSets - Add `OpcUaStateTypeIndex` and wire it through `ModelSourceGenerator` / `ModelCompilation` so standard (`ns=0`) node-state and method-state class names are resolved from referenced `Opc.Ua.Core(.Types)` metadata. - Add the model-generation-scoped `StandardMethodStateFallback`, which degrades an unresolved standard typed `*MethodState` reference to `global::Opc.Ua.MethodState` only when the type is neither available in the compilation nor declared by the current generation pass. - Keep declaration names outside the reference-only fallback policy, propagate fallback state through the logical execution context, reuse the immutable availability index, and use named incremental-generator inputs instead of deep `Left` / `Right` chains. - Escape generated fluent-builder XML documentation where browse names can contain XML-sensitive characters. ### Safe NodeState factory emission - Declare one base-typed `global::Opc.Ua.NodeState nodeState = state;` local per generated factory. - Use `nodeState` for base-member reads and writes to `NodeId`, `SymbolicName`, `BrowseName`, `DisplayName`, `Description`, `WriteMask`, `UserWriteMask`, `AccessRestrictions`, `ReleaseStatus`, `Categories`, `Specification` and `IsPartOfTypeHierarchy`. - Base-qualify the optional-child `previousNodeId` read, NodeId comparison, and existing-child NodeId update. - `global::`-qualify emitted `NodeId` / `ExpandedNodeId` namespace prefixes to avoid namespace collisions. ### Supporting updates - Expose `Opc.Ua.Types` internals to `Opc.Ua.Core.Encoders.Tests`. - Update generator assertions and add focused fallback regression coverage. ## Why Compiled companion models can instantiate standard types whose curated Core implementation does not expose the conventionally named typed method-state class. The scoped fallback lets those models generate without weakening the Stack generator or masking classes emitted by the current model. Separately, generated subclasses can shadow base `NodeState` properties with strongly typed `new` properties. Routing base attributes through a `NodeState`-typed local guarantees initialization reaches the intended base member while keeping generated code smaller and clearer than repeated casts. ## Validation - Full `Opc.Ua.SourceGeneration.Core.Tests` on net10.0: **3718 passed / 8 skipped / 0 failed**. - Combined focused generator coverage on net48: **21 passed / 0 failed**. - Full `Opc.Ua.SourceGeneration.Tests`: **68 passed / 0 failed**. - Full `Opc.Ua.SourceGeneration.Stack.Tests`: **90 passed / 0 failed**. ## Context This PR supersedes #4062 and contains both source-generator change sets. The companion-model fallback remains the scoped interim workaround tracked by #4060; a future upstream name-resolution step can remove it. These changes also feed the experimental data-encodings work in #4007. --------- Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> |

CTT follow-up: monitored items, alarms, codecs, history, and model validation (#4002)
# Description Follow-up to #3978 based on the latest OPC UA CTT aggregate, matrix, Historical Access, Attribute, and Node Management runs. ## Aggregate run 16 - Ignore synthetic `BadBoundNotFound` raw-bound markers when feeding aggregate calculators. - Add direct and live historian regression coverage. ## Multi-dimensional Variant matrices - Fix `Variant.Copy()` so rank-2 Variant matrices preserve their payload and dimensions. - Enforce valid Variant matrix dimensions consistently across Binary, JSON, XML stream, and XML parser codecs. - Encoders return `BadEncodingError`; decoders return `BadDecodingError` for malformed matrix dimensions. - Add cross-codec valid/null/empty/malformed tests and a batched ReferenceServer Read regression. - Correct the previous CTT issue attribution: the invalid `Scalar_Static_Arrays2D_Variant` server encoding poisoned the batched CTT Read. ## Node Management AddNodes - Return `BadNodeIdRejected` for unsupported requested-NodeId namespaces. - Validate hierarchical ReferenceType source/target NodeClass constraints. - Document run-18 confirmation that all remaining 15 AddNodes errors are CTT project/script configuration issues. ## Historical Access and Attribute Services run 18 - Reject whitespace in `NumericRange` syntax with `BadIndexRangeInvalid`. - Add HistoryRead tests for operation-level invalid syntax and per-DataValue `BadIndexRangeNoData`. - Document CTT defects: - `012.js` expects `BadIndexRangeNoData` at the operation level instead of on returned DataValues; - `Err-012.js` uses a non-historizing node for an access-denied test; - generic Attribute array helpers omit NodeId[] and StatusCode[] conversion paths. ## Base Information model validation run 19 - Run the CTT main session as `sysadmin` over Basic256Sha256 SignAndEncrypt so SecurityAdmin RolePermissions and EncryptionRequired restrictions are both satisfied without weakening the server model. - Preserve predefined well-known NodeIds while making generated dynamic type and optional-child factories allocate compatible per-instance NodeIds, remap internal references, and update references from the owning subtree. - Materialize dynamic RoleType properties through generated helpers and keep role-child string NodeIds disjoint from numeric RoleManager root IDs. - Add net48/net10 regressions for generator output, NodeId allocation/reference remapping, DI mandatory children, dynamic roles, and low-privilege versus SecurityAdmin Browse visibility. - Document CTT defects for permission-unaware mandatory-child validation, the UA 1.04 reference model used against a UA 1.05 server, stale ServerDiagnostics cache, and the `ConformanceUnits` scalar/array mismatch. ## Related Issues - Follow-up to #3960 and #3978. ## Checklist - [x] I have signed the CLA and read the CONTRIBUTING document. - [x] Tests prove the fixes and improve coverage. - [x] Required CTT documentation is updated. - [x] Focused builds/tests introduce no warnings. - [x] Affected tests pass on .NET Framework and .NET 10. - [ ] CI and CodeQL are green. - [ ] All PR feedback is addressed. ## Latest CTT full run and A&C run 20 - Fix Monitor Value Change V2 `036.js`: an ambiguous `DataValue(StatusCode)` call encoded `BadIndexRangeNoData` as a Good value. - Prove all 19 configured matrix monitored items notify when the selected value actually changes; document the independent `042.js` script defects. - Rebase dynamic `CertificateExpired` / `TrustListOutOfDate` alarm roots and descendants, restore standard type declarations and ModellingRules, and expose the cross-node-manager references. - Deliver method-triggered events to every authorized Session, fixing the two-Session Confirm scenario. - Preserve locale-only `LocalizedText` values consistently across Binary, JSON, and XML and align Acknowledge/Confirm comment behavior and tests. - Document the remaining proven CTT defects for TransactionDiagnostics, SemanticChange, History `013`, PolicyId scope, A&C, durable subscriptions, and Subscription Minimum events. ## Base synchronization Merged `master` through `007cfaf90` (`#4010`, repository layout consolidation) and retained the matrix regression tests at their new `tests/` locations. ## Latest validation - Focused merged-tree tests pass on net10 and net48. - `Opc.Ua.Server` and `Quickstarts.Servers` Release builds complete with 0 warnings and 0 errors on net10 and net48. - The existing `DisableEnableViaTypeAndInstanceMethodNoEventsDuringDisabledAsync` timing test took its documented inconclusive timeout path after the layout merge; no test failure was reported. --------- Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> Co-authored-by: Copilot <198982749+Copilot@users.noreply.github.com> Co-authored-by: romanett <romanett98@gmail.com> |

Add ISA95 JobControl and ManagedSession regression coverage (#3998)
## Summary - Adds the official ISA95 JobControl 2.0.0 NodeSet2 as a complete source-generator regression fixture. - Extends the lightweight generated-stack test stub with `NamespaceMetadataState`, required by the complete model. - Adds a deterministic ManagedSession cancellation regression proving that a started connect attempt is stopped. The ManagedSession cleanup implementation and Quickstarts utility coverage now come from `master`; this PR retains the additional deterministic cleanup regression. ## ISA95 fixture provenance and integrity The fixture is byte-for-byte the official file: - Source: `OPCFoundation/UA-Nodeset@e0b5d80cfff698f0276393e28df138a7fbc4b541` - Path: `ISA95-JOBCONTROL/opc.ua.isa95-jobcontrol.nodeset2.xml` - Git blob: `82f008cd126ade54e5f2c737bcc116621a8c3087` - SHA-256: `52327e736beb604c7253a5a5393d1ad525b9ecf35b71fbacb4f429cacb334064` The fixture test retains the OPC Foundation MIT header and verifies the 2.0.0 model/date, 258 nodes (including 134 variables), representative late variables, and that every `ns=1` reference target resolves locally. ## Validation - ManagedSession tests: 17 passing on net10.0; 15 passing and 2 framework-gated skips on net48. - Quickstarts server utility tests: 3 passing on net10.0 and net48. - ISA95 generator and fixture integrity regression: 5 passing on net10.0. |
