Update NuGet dependencies and migrate tests to NUnit 5 (#4840)
# Description Update 55 NuGet dependencies to the latest stable releases available on 2026-10-19, preserving documented compatibility pins and framework-specific version bands. Existing OpenUSD prereleases remain unchanged because no newer releases are available. Migrate existing tests to NUnit 5: await asynchronous assertions, propagate async through helpers, handle nullable predicates, and replace obsolete `Order` attributes with sequencing dependencies. Sequencing dependencies use `AllowFailure = true`; filtering a dependent test also runs prerequisites. Adjust fixture-level parallelism where NUnit dependency scheduling requires it. Keep Roslyn API/runtime pins intact; select newer Immutable/Metadata runtime packages only for test and profiling hosts requiring them. Update the approved SDK pin to 10.0.402 across local, CI, and container builds. Document NUnit 5 conventions. |

Add recycling operator console and sample container images (#4810)
# Description Add a local browser-based operator console for the synthetic recycling line, using direct, encrypted OPC UA connections and the existing typed coordination interface. - Extract a sample-local, non-packable `Recycling.Client` library shared by the server and console. Preserve the model XML bytes, namespace/type identifiers, resource identity, wire format and journal schema; the server retains its .NET 8/9/10 targets. - Add a .NET 10 ASP.NET Core workstation host with bounded SSE state/trend delivery, native companion inspection, paged material/genealogy reads, and role-limited coordinator commands. Exact command envelopes are retained for explicit retries; uncertain outcomes are not automatically reissued. - Add the operator interface using local HTML/SVG, CSS and JavaScript modules: ten process groups, substep inspection, faults/constraints, persistent quality holds, trends, material tracing and simulator administration. Show raw quality/provenance and handle stale data, run changes, browser expiry and large identifiers explicitly. No browser-generated plant telemetry or frontend framework/npm build is introduced. - Keep application/user credentials in external certificate stores. Use strict X.509 trust, signed/encrypted UA sessions, local browser bootstrap sessions, same-origin/CSRF checks, and a conservative configured control ceiling. This is a local synthetic sample, not a physical emergency-stop or shared remote-user system. - Register `recyclingserver` and `recyclingclient` in the existing Images CI matrix, using source/prebuilt Dockerfile stages and the existing portable-IL/multiarchitecture packaging flow. Add an optional loopback-published Compose console service. No new schedules or NuGet publication entries are added. - Add managed, real-UA, Chromium, NativeAOT and image-contract qualification, with Microsoft.Playwright as a test-only centrally managed dependency, and update usage/deployment documentation. ## Checklist _Put an `x` in the boxes that apply.

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. Tests have not been run locally yet. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com> |

Server subscriptions: fix spec defects in Subscription/MonitoredItem handling found by audit (#4629)
# Description Fixes defects found in a spec-grounded audit of the server **Subscription / MonitoredItem** implementation (`src/Opc.Ua.Server/Subscription/**`, `NodeManager/MonitoredItem/**`, `EventManager`, monitored-item service dispatch and filter validation). Each behaviour change was checked against OPC 10000-4 (§5.13, §5.14, §7.21, §7.22), Part 5 (subscription diagnostics) and Part 9 (ConditionRefresh). Every fix has a regression test. The audit found 56 defects (1 Critical, 3 High, 20 Medium, 32 Low). A follow-up max-effort code review of the fix branch found 27 more issues, mostly introduced by the first round of fixes. All but one are fixed here. ### Most important fixes - **Critical — remote hang:** an `AggregateFilter` with `processingInterval = NaN` was not revised, and `AggregateCalculator` looped forever while holding the node-manager lock, so one CreateMonitoredItems request blocked the node manager. Non-finite, ≤0 and sub-tick intervals are now revised (Part 4 §5.13.2.1), and the calculator rejects them as a backstop. - **Monitored-item limits:** new `ServerConfiguration.MaxMonitoredItemCount` / `MaxMonitoredItemsPerSubscription`; Bad_TooManyMonitoredItems is returned when a limit is hit, and ServerCapabilities now report the limits. Both default to `0` (no limit), so existing behaviour is unchanged. - **Sampling groups:** a client could get one dedicated thread per distinct sampling interval above 1 h; intervals above the last rate group are now rounded, and the loop is async. An item could also end up in two sampling groups and keep being sampled after it was deleted. - **Subscription state machine** (Part 4 §5.14.1.2): - the lifetime counter resets while a Publish is queued and counts otherwise; - the lifetime and keep-alive stay within `MaxSubscriptionLifetime`; - LatePublishRequestCount is counted once per entry into LATE; - messages held while publishing is disabled are no longer sent, and are not offered by Transfer/Republish either; - ConditionRefresh returns Bad_RefreshInProgress for any refresh already queued or running on the subscription. - **Triggering** (Part 4 §5.13.1.6): - linked items are triggered by an item still draining a backlog, by the first value after re-enable, and by an item created Disabled; - links are persisted for durable subscriptions; - Disabled/Sampling items follow the publish rules in the shared pipeline, so custom `IMonitoredItem` implementations follow them too. - **Queues** (Part 4 §5.13.1.5, §7.21): - no duplicate value after a queue-size increase; - EventQueueOverflow events are placed where the events were lost, including on queue shrink; - the duplicate-event check scans the newest entries; - EventQueueOverflowCount and MonitoringQueueOverflowCount are maintained correctly; - changing select clauses rebuilds queued events in the new layout, and is safe on durable queues and on failure. - **Filters:** - per-clause EventFilterResult instead of rejecting the whole item (Part 4 §7.22.3); - corrected status codes: Bad_DeadbandFilterInvalid, Bad_MonitoredItemFilterInvalid, Bad_EventFilterInvalid, Bad_MonitoringModeInvalid, Bad_TimestampsToReturnInvalid; - aggregate filter in subscriptions: processing interval at least 2× the revised sampling interval, revised StartTime on the requested grid, ServerTimestamp = end of interval (Part 4 §7.22.4). - **Lifecycle and races:** - expired subscriptions are always cleaned up, even when the session closes during cleanup; - Create/Transfer racing CloseSession returns Bad_SessionClosed; - session diagnostics counts no longer drift; - a large but valid Publish TimeoutHint no longer fails the request; - a ready subscription is served by queued Publish requests instead of going Late; - restored persisted state is validated. - **Access:** a value change notification is checked against each subscriber's UserAccessLevel, not the writer's. - **Redundancy / durable store:** - the first-unsent sequence number is mirrored; - sequence numbers are no longer reused after a second failover; - triggering links are stored (definition format 6, written only when links exist, so older replicas can still read link-less subscriptions). ### Behaviour changes reviewers should know - With the default config, publishing intervals above `MaxSubscriptionLifetime / 3` (1,200,000 ms) are revised down, so lifetime ≥ 3×keep-alive fits the configured maximum. - The revised keep-alive is capped at a third of the max lifetime. - Idle subscriptions expire after exactly MaxLifetimeCount cycles without a queued Publish. - A partly invalid EventFilter select list is accepted with per-clause errors. The public `EventFilter.Validate` keeps Status Good if at least one clause is valid; callers that cannot return per-clause results must also check the new `EventFilter.Result.HasSelectClauseErrors`. There is a migration note in `docs/migrate/2.0.x/sessions-subscriptions.md`. - Aggregate processing intervals may be revised higher (≥ 2× sampling interval); aggregate ServerTimestamp is now the interval end. - Sampling intervals above 3,600,000 ms are rounded to multiples of 900,000 ms (default rate groups). ### Public API Additive only: - `ServerConfiguration.MaxMonitoredItemCount` and `MaxMonitoredItemsPerSubscription`; - `EventFilter.Result.HasSelectClauseErrors`; - `IStoredSubscriptionTriggering`, `ISubscriptionRetransmissionSendStateStore`, `SubscriptionRetransmissionState.FirstUnsentSequenceNumber` (optional store capabilities, detected with `as`); - new `EventQueueHandler` constructor overloads. ### Known open items (not in this PR) - **Part 4 §5.13.2.1:** CreateMonitoredItems should create an item even when the user lacks Read permission and report the error in Publish. This is not done: the create-time RolePermissions check is the only role check on the initial value, so following the spec would leak values until every node manager re-checks per sample. - **Sampling loop:** it runs on thread-pool threads; node managers with blocking synchronous reads should not use sampling groups heavily. The alternative, a dedicated thread per group, was the thread-exhaustion issue fixed here. - **Restarts:** a pending QueueSize-1 value and a pending overflow flag are not kept across a restart; that needs persistence interface extensions. - **Limit defaults:** decide whether the new limits should get finite defaults (currently 0 = unlimited). ## Related Issues - No tracking issue; the findings come from an internal audit of the server subscription code. ## 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. - [ ] 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. ### Local verification (net10.0, all green) | Suite | Passed | Failed | |---|---|---| | Opc.Ua.Server.Tests | 7963 | 0 | | Opc.Ua.Subscriptions.Tests | 643 | 0 | | Opc.Ua.Subscriptions.Classic.Tests | 57 | 0 | | Opc.Ua.Subscriptions.Durable.Tests | 36 | 0 | | Opc.Ua.Redundancy.Server.Tests | 847 | 0 | | Opc.Ua.Core.Tests (filter tests) | 283 | 0 | net48 build of `Opc.Ua.Server.Tests`: 0 errors. net48 tests and the full UA.slnx were not run locally. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com> Co-authored-by: Marc Schier <marcschier@users.noreply.github.com> |
