WoT: move GeneratesEvent off Object instances (OPC 10000-3 §7.15) (#4706)
Fixes #4669. OPC 10000-3 §7.15 says the SourceNode of `GeneratesEvent` "shall be an ObjectType, a VariableType or a Method". CTT `Base Info Core Structure 2 001.js` flags every Object that is the source of one. #4667 fixed this in the source generator. This PR fixes the three remaining WoT places. ### 1. WotCon asset registry - `AssetRegistry.BuildEventNode` / `RemoveEventTypes` no longer add or remove `GeneratesEvent` from the asset Object. Event delivery already relies on `EventNotifier = SubscribeToEvents` and root-notifier registration. - Tests now assert the reference is **absent** and the notifier bit is set. The re-apply test asserts that the old EventType node is gone. ### 2. WoT NodeSet converter (`src/Opc.Ua.Types/Wot`) - **TD → NodeSet:** a last pass (`RelocateInstanceGeneratesEvent`) moves forward `GeneratesEvent` references off an Object/Variable root: - An event the bound type already declares needs nothing more. Matching is by qualified BrowseName against the local context's declarations, the same rule as the declaration merge. - Any other event is declared by a synthesized non-abstract `<rootLocal>Type`. It derives from the bound type (or from `BaseObjectType` / `BaseDataVariableType` when the TD binds none) and becomes the instance's `HasTypeDefinition`. A Variable root gets a `UAVariableType` with the instance's DataType and ValueRank. - Thing Models are unchanged: the projected type keeps its `GeneratesEvent`. - **NodeSet → TD:** - An instance's event affordances are now collected from its type definition and that type's supertypes. Instance-level `GeneratesEvent` is still read for third-party NodeSets. - In a single readable document, a type that only carries one instance's events (only `HasSubtype` + `GeneratesEvent`, typing exactly one instance) is not chosen as root. It is folded back: its supertype becomes the type binding, and no link is written when that supertype is the default base type. The TD → NodeSet → TD round trip stays readable, with no `uav:nodes` fallback. - A document set gives the carrier its own Thing Model, and the instance TD binds to it. - **Archive check:** an event affordance is accepted when the root's type definition, or one of its supertypes, generates it. - `docs/WoTNodeSetConversion.md` documents the behaviour in a new "Event source" row. ### 3. Aggregation sample - `SamplePump.NodeSet2.xml`: each pump is typed by its own `PumpType` subtype, `ns=1;s=Pump1.Type` (`Pump_1Type`) and `Pump2.Type`, which declares its alarm EventTypes. - It is per pump because each pump owns its alarm EventTypes. `Pump2.Type` is cloned with the rest of Pump2. - The pumps keep `EventNotifier="1"` and no longer carry `GeneratesEvent`. - The checked-in documents are regenerated, adding `sample-pump-pump-1type.json` / `-2type.json`. The pump TDs still list the alarm event affordances. - The sample binding lookup ignores Thing Models, because the type's TM declares the same EventType as the pump TD. A declaration missing from the instance still fails as before. - Docs: `WoTConnectivity.md` (asset event affordances, §12.4.2) and `WotBindings.md`. The `GeneratesEvent` clause in the sample-limitation note was already stale, so I removed it. ### Runtime check `WotNativeOwnershipIndex` only uses `GeneratesEvent` in its alias table. Projected event routing takes the owner from `uav:componentOf` / `uav:id` and the notifier from Parent/`HasNotifier`. Nothing in `Opc.Ua.WotCon.Server` reads an instance-level `GeneratesEvent`. ### Tests (net10.0) - `Opc.Ua.Types.Tests`: 11446 passed, 1 skipped. New `WotInstanceEventSourceTests` covers object and variable roots, TMs, the TD with no events, the folded round trip, the legacy instance reference and the document set. Two bound-type cases were added to `WotDeclarationMergeBoundaryTests`. - `Opc.Ua.WotCon.Bindings.Tests`: 714 passed. - `Opc.Ua.WotCon.Tests`: 1496 passed, including the byte-exact sample regeneration tests. - net48 build of both test projects is clean, and `dotnet format whitespace` is clean. Not run: CTT `Base Info Core Structure 2 001.js` (p02-base-info) against a WotCon server. 🤖 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> |

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> |

Fix Core/Types audit findings and conform them to the OPC UA spec (stacked on #4569) (#4573)
> **Stacked on #4569.** The base branch is `romanett/practical-murdock-fd9c56`, so this diff shows only the commits of this PR. Retarget to `master` after #4569 merges. ## Summary Bug audit of `Opc.Ua.Core`, `Opc.Ua.Core.Types`, `Opc.Ua.Types` and `Opc.Ua.Core.Schema`, with the findings fixed and the fixes grounded against the OPC UA specification (reference.opcfoundation.org). 133 commits in four groups: 1. **Audit fixes** (`Fix <ID>: ...`): 116 findings from a read-only audit, each with a regression test. IDs follow the audit scopes: T1-T6 `Opc.Ua.Types`, C1-C4 `Opc.Ua.Core`, S1 `Opc.Ua.Core.Types` + `Opc.Ua.Core.Schema`. 2. **Review fixes** (`Fix review <ID>: ...`): issues a code review of group 1 found, plus lower-severity leftovers. 3. **Spec fixes** (`Spec: #<n> ...`): the 18 places where an earlier fix only partly matched the spec text. 4. Test and analyzer follow-ups. Where `master` (#4516, #4522, #4540, #4564) or #4569 already fixed the same issue, their version was kept and this PR only adds what they didn't cover. ## Behaviour and user-facing changes ### Wire format and interoperability (breaking) - **PubSub AES-CTR (Aes128-CTR / Aes256-CTR)** now follows Part 14 Tables 156/157: - The counter block is `KeyNonce[4] | MessageNonce[8] | BlockCounter[4]`, and the block counter starts at 1. - The SecurityHeader nonce is 8 bytes: `Random[4] | UInt32 SequenceNumber`, with the sequence number starting at 1. - SKS key data is split with a 4-byte KeyNonce, giving 52 / 68 bytes. - **Not interoperable with earlier releases of this stack**, but matches the spec. There is a test against the independent RFC 3686 vector. - **User token signature** (Part 4 6.1.8): - The signed data is now built from the user token policy's SecurityPolicy on both client and server. - It also supports the SecurityMode None layout `ServerNonce | HASH(ServerCertificate) | ClientNonce`. - New overload `SecurityPolicyInfo.GetUserTokenSignatureData(..., MessageSecurityMode)`. - **Secure channel:** - The ECC AEAD `LastSequenceNumber` is correct across the 32-bit sequence wrap (Part 6 6.8.1). - The incoming chunk counts against MaxChunkCount/MaxMessageSize. - The sender no longer lets a message through that is 24 bytes over MaxMessageSize. - The OPN response signature is verified without overrunning the buffer (RSA_DH with differing key sizes). ### Sessions (server) - **CreateSession nonce:** - The client nonce is kept on None channels, because the None-mode user token signature covers it. - A nonce over 128 bytes returns `Bad_NonceInvalid` on every channel (Part 4 5.7.2.3). - The duplicate-nonce check runs only on secured channels. - A non-empty nonce under 32 bytes is still accepted on None, for compatibility. - **ActivateSession:** an embedded `EccEncryptedSecret` signing certificate is validated with the server's peer certificate validator (Part 6 6.8.3). Byte equality with the client certificate is only the fallback when no validator is available. New opt-in interface `ICertificateValidatorProvider`. - **FindServers / GetEndpoints:** `GatewayServerUri` and `DiscoveryProfileUri` are no longer swapped. ### Write, Read and Call (NodeState / node managers) - **UserWriteMask:** - Enforced for non-value attributes and for VariableType Value writes (`ValueForVariableType`), returning `Bad_UserAccessDenied`. - An unconfigured UserWriteMask (0, no handler) is not enforced, and reads back as the WriteMask so Read and Write agree (Part 3 8.60). - A throwing or Bad `OnReadUserWriteMask` handler fails only that item. - **Index-range writes:** - Slices are merged into the cached value under the attribute lock, also for `OnWriteValueAsync` handlers. - A data-change notification is still produced when the cache cannot absorb the slice. - The slice must match the unclipped range, otherwise `Bad_IndexRangeDataMismatch` (new status code in `Opc.Ua.Types`). - A range past the target returns `Bad_IndexRangeNoData`. - A handler without index-range support returns `Bad_WriteNotSupported` (Part 4 7.27, 5.11.4.4). - **Index-range reads on matrices** return partial results clipped to the source, instead of allocating the requested size (a Read with `"0:40000,0:40000"` no longer allocates about 1.6e9 elements). - **DataTypeDefinition writes:** - A value that isn't a decoded DataTypeDefinition, or whose kind doesn't match the DataType category, returns `Bad_TypeMismatch`. - Null is rejected for concrete Structure/Enumeration/OptionSet types. - WriteMask is checked first (Part 3 5.8.3). - **AnalogItem:** a null write skips the InstrumentRange check again. - **Method call:** the async fallback passes the ObjectId to the method handlers. - **Redundancy:** `DistributedValueParticipation` merges index-range writes and applies the index range on reads. - **Change masks:** `ClearChangeMasks` takes the bits atomically, so concurrent changes are no longer lost. - **`AccessLevelEx`:** preserved by Clone/Export. ### Alarms & Conditions (Part 9) - **Acknowledge / Confirm / AddComment:** - Accept any EventId the condition or its branches reported while that state is still pending (5.7.3). - An unknown id returns `Bad_EventIdUnknown`. - An already handled state returns `Bad_ConditionBranchAlreadyAcked` / `...AlreadyConfirmed`. - AddComment on a branch no longer changes the trunk, and the branch table is re-keyed when a branch's EventId changes. - **Shelving:** - OneShotShelve without MaxTimeShelved no longer overflows the timer. - A timed shelve is measured on the monotonic clock, so wall-clock steps don't delay the unshelve. - The state is named `OneShotShelved`. - **Audit events:** - They report failure for rejected method calls. - `SelectedResponse` is a UInt32. - A rejected negative Respond leaves SelectedResponse unset. - **`ContentFilterElement.Validate`:** an unknown FilterOperator is reported per element as `Bad_FilterOperatorInvalid`, instead of failing the whole service call. ### ContentFilter evaluation (Part 4 7.7.3, on top of #4564) - **Bitwise operators:** - The result takes the size of the larger operand. - Boolean, numeric String and one-element array operands are converted to integers implicitly. - Types without an implicit integer conversion give NULL. - **Strings:** ordering is ordinal, no longer culture dependent. - **Cast:** restricted to the Table 121 conversions, and QualifiedName to LocalizedText is added. The general `Variant.ConvertTo` keeps its wider set. - **Null and empty operands:** - `Like` with a NULL operand is NULL. - Empty arrays of the same DataType compare equal. - Null-string operands are NULL everywhere. ### Encoders and built-in types - **XML:** - Strings keep leading, trailing and whitespace-only content (Part 6 5.3.1.5). NodeSet import opts back into treating whitespace-only strings as empty with the new `XmlDecoder.TreatWhitespaceOnlyStringsAsEmpty`. - Layout whitespace around `<Identifier>` values is ignored, and trailing control characters are stripped from `s=` ids. - `XmlElement` ignores DTDs without expanding entities. - **JSON:** - A DateTime without an offset is read as UTC. - An unmappable `nsu=` NodeId and an unknown `svu=` ExpandedNodeId decode to a namespace-0 String NodeId (5.4.2.10 / 5.4.2.11). - `svr=` is rejected in a NodeId field. - Bad matrix dimensions return `BadDecodingError`. - The non-strict body stack stays balanced after an error. - The nesting limits match between encoder and decoder. - **Binary:** - `MaxByteStringLength` no longer applies to strings. - ExtensionObject bodies count toward the nesting limit on seekable streams (and in the XML encoder). - **Parsing:** - The NodeId parser requires `i=`/`s=`/`g=`/`b=`. - `ExpandedNodeId.Parse` rejects an empty `nsu=`/`svu=`. - NumericRange rejects a trailing `,` with `Bad_IndexRangeInvalid`. - RelativePath escapes `#`. - **Status codes:** `StatusCode.WithSubCode`/`WithCodeBits` keep the severity bits and look up the symbolic id for the new code. - **Variant / VariantHelper:** - `TryCastTo` returns false on a type mismatch. So `DataValue.GetValue<T>(default)` returns the default, and `GetValueOrDefault` / `CastTo` throw `BadTypeMismatch` as documented. - `System.DateTime` casts are supported. - Concrete encodeable arrays (e.g. `Argument[]`) no longer throw. - `ConvertTo` keeps one-element and empty arrays as arrays and checks the conversion is legal for empty arrays. - `CastFrom(object[])`, `CastFrom(Enum[])` and the obsolete `Variant(object)` constructors keep the array shape (previously a one-element array collapsed to a scalar and an empty one to Null). - `TypeInfo.Unknown` / `Variant.Null.TypeInfo` report `ValueRanks.Any`. - **Equality and hashing contracts fixed:** - Types: Matrix/MatrixOf, typed-null Variants, NodeId (the namespace index is now hashed), ExpandedNodeId, LocalizedText, DiagnosticInfo, StructureDefinition/EnumDefinition, CertificateIdentifier, UserIdentity and DateTimeUtc. - `MatrixOf.Dimensions` returns a copy. - Decimal equality and hashing now run in bounded time. - **Localized text:** a LocalizedText with locale `"mul"` and no usable translations, or null client locale ids, no longer throw. ### NodeSet, address space and utilities - **NodeSet export/import:** - Server index 0 is the local server on import and export, so local ids are no longer written as `svr=65535`. - `StructureDefinition.BaseDataType` is filled from the supertype on import. - **`NodeTable.Import`:** replaces duplicates, keeping the references neighbouring nodes hold. `TypeTable.Add` detaches a re-parented type from its old supertype, and `Node.Clone` gets its own ReferenceTable. - **`StringTable` / `NamespaceTable`:** capped at UInt16 indexes (`BadEncodingLimitsExceeded`) for Append and Update, instead of silently wrapping. - **Small fixes:** - `UnsecureRandom.Shared` is seeded randomly. - The peer's RetryAfterMs is clamped to one day. - The `CancelAsync` and `string.GetHashCode(StringComparison)` polyfills match BCL behaviour. - `CoreUtils.IsEqual` compares strings ordinally. ### Schema generation and ComplexTypeSystem - **JSON schema:** describes the 1.05 layout with the compact/verbose null rules, and now validates real `JsonEncoder` output. - **XSD:** - `EncodingMask` (`xs:unsignedLong`) only for StructureWithOptionalFields. - Guid and StatusCode are complex types. - Standard types are in the `Types.xsd` namespace. - **Structure-backed OptionSets** are described as `{Value, ValidBits}`. New `UaTypeDescription.IsStructureOptionSet` property and constructor overload. - **ComplexTypeSystem:** - A malformed type in a server dictionary is skipped per type instead of discarding the whole dictionary. - Cyclic supertype walks are bounded. - Declared definitions are no longer changed. - A dictionary validator is kept only if the dictionary parsed. ### Certificates and trust lists (Part 4 6.1.3, Part 12) - **Revocation:** - Checked for issuers supplied in the peer's chain and for inline-trusted issuers, against the CRLs in the trusted and issuer stores. - A store without CRL support no longer hides "revocation unknown". - `RejectUnknownRevocationStatus` is honoured for inline-trusted issuers unless the entry sets `SuppressRevocationStatusUnknown`. This changes the strict case of `ExplicitIssuerChainIsHonoredWithoutStorePathAsync`. - **Basic constraints / path length** violations fail with `Bad_CertificateInvalid`. - **`TreatAsInvalid`:** - Now yields `Bad_CertificateUntrusted`, which can't be suppressed or auto-accepted. - It is honoured on individual trust-list entries even when the certificate is also in a store. - **`EccEncryptedSecret`:** enforces the result of validating the sender certificate. - **`TrustListTransaction`:** - Routes each CRL to the store holding its issuer (TrustedCrls/IssuerCrls). - Validates staged CRLs, including the store's CRL support, before changing anything. - Applies certificates before CRLs. - **Other:** - One failing `CertificateChanges` observer no longer stops the others. - `InMemory:` stores share their contents per path, and `InMemoryStoreProvider` is `IDisposable`. ### WoT (`Opc.Ua.Types/Wot`) - **Projection security:** projection security schemes whose qualified names collide are refused. New diagnostic `WotDiagnosticCode.ProjectionSecurityConflict = 6063`. - **Input handling:** - Invalid Unicode (lone surrogates, bad UTF-8) is rejected as `JsonException`. - External-schema results are keyed per affordance. - A duplicate security-floor member is rejected. - `nsu=` ids are percent-encoded (Part 6 5.1.12). - The configured JSON depth is honoured on re-parse. - An oversized document is reported before it is parsed back. - **Performance and limits:** - Subtype-graph validation, `componentOf` linking and the namespace table are now linear. - Namespaces are capped at UInt16. ### New or changed public API - `ICertificateValidatorProvider` (server) - `SecurityPolicyInfo.GetUserTokenSignatureData(..., MessageSecurityMode)` overload - `XmlDecoder.TreatWhitespaceOnlyStringsAsEmpty` - `UaTypeDescription.IsStructureOptionSet` plus a constructor overload - `WotDiagnosticCode.ProjectionSecurityConflict` - `StatusCodes.BadIndexRangeDataMismatch` in the `Opc.Ua.Types` list - `InMemoryStoreProvider : IDisposable` ## Not changed / open - **Deferred:** - S1-14 (BSD OptionSet size needs the base type in `UaTypeDescription`, and BSD is deprecated). - C2-7 (restoring the own-certificate trust exemption would accept certificates the spec says to reject; removing the dead code is a separate decision). - A1-4 (config values keep surrounding whitespace, as the pre-April-2026 loader did). - H-2 (JsonDecoder has no real nesting counter). - A2-3 (the StringTable cap also applies to diagnostics tables; default `MaxArrayLength` already bounds them). - **Needs a product decision:** - The general `ConvertToString` writes a QualifiedName as `ns:Name`, while Table 121 drops the namespace. - Short (< 32 byte) client nonces are accepted on None channels. ## Verification - Every commit added a regression test that fails without its fix, where practical. - Before the rebases, with all audit and review fixes (before the `Spec: #…` commits): 0 build warnings and 16 test suites green on net10.0. The suites: Types, Core, Core.Encoders, Core.Security, Core.Schema, Client, Client.ComplexTypes, Server, Sessions, Gds, History, Features, Redundancy.Server, PubSub, WotCon and WotCon.Bindings. Core hit its known intermittent end-of-run hang once, and reruns were clean. - The `Spec: #…` fixes were verified per group on their own suites. Those include PubSub.Udp, Redundancy.PubSub, PubSub.Server, Configuration and SourceGeneration.Core. - **Not yet built or tested on this base.** It was rebased onto master (resolving overlaps with #4522, #4540 and #4564) and then onto #4569. This PR stays a draft until the full run on this base is green. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Opus 5.5 <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> Co-authored-by: Marc Schier <marcschier@users.noreply.github.com> |

Fix audit findings and review regressions across the OPC UA stack (#4503)
## Scope Audit fixes and review follow-ups across the OPC UA Core, Client, Server, transport, and redundancy components. This includes implemented Tier 1, Tier 2, and Tier 3 work; it does not claim that every item in the 244-finding audit backlog is complete. The review batch fixes mandatory full-key record protection and owned plaintext buffers; transactional pending-certificate claims; shared-channel nonce and certificate ownership; discovery and token-policy validation; reconnect/callback ordering without changing unbounded buffering defaults; server permissions, filters, monitored-item lifetime, and alarm topology; historian paging, retention, and annotations; atomic user/password metadata; and canonical file identities with bounded alias and role refresh workers. ## Review-batch verification at `ab686ccae` The following results come from fresh test builds using `dotnet test`, `--no-restore`, `-m:1`, and an explicit `CustomTestTarget`. They replace the earlier description's library-build/`--no-build` totals, which did not establish the state of the merged test sources. | Scope | Target | Passed | Skipped | |---|---|---:|---:| | Core review regressions | net10.0 | 827 | 0 | | Client and lifecycle regressions | net10.0 | 630 | 0 | | Server review regressions | net10.0 | 1970 | 0 | | Redundancy Server / Client / PubSub | net10.0 | 276 / 10 / 11 | 0 | | Sessions / file-and-alias / streaming / HTTPS-WSS integration | net10.0 | 8 / 21 / 30 / 20 | 0 | | Core review regressions | net48 | 786 | 39 | | Client recovery and policy regressions | net48 | 54 | 0 | | Server ownership, aliases, queues, and user-state regressions | net48 | 137 | 0 | Every listed run exited successfully. The 39 net48 skips are existing platform/capability cases. New key-agreement tests assert unavailable-policy behavior on unsupported targets rather than adding skips or pretending those targets performed an unsupported handshake. Additional exact node/permission/filter/alarm checks passed 13 Core and 46 Server cases. The PR-scoped formatter verification covers 26 projects and 389 non-generated C# files. A Roslyn syntax audit covers 53 changed interfaces and 263 members, with no missing parameter/type-parameter/return contracts and a 120-column limit for their declarations and documentation. No full-solution, all-target-framework, or NativeAOT matrix is claimed from these local runs; the new CI run must establish its own result. ## CI follow-up at `e1bc3ac3b` The follow-up fixes the failures reported by Azure build 18400. TLS certificates retain configured DNS names, including mixed-case URI schemes, without relaxing hostname validation. Reverse-WSS fixtures use the DNS identity in the client certificate. Reconnect completion is published only after cycle cleanup, so a subsequent reconnect cannot join an old completed cycle and retain old certificates. Certificate-alarm roots now support event subscriptions. The pump sample has one continuous notifier path, with no duplicate shortcut. Historian and aggregate fixtures share the provider's retention clock. Alarm collection lets the server expire idle Publish requests rather than canceling only the client wait. The corrected server, WoT, and managed-session fixtures exercise valid requests and initialized lifecycle contracts. Downlevel crypto tests preserve real credential and key-ownership assertions without enabling unsupported raw-ECDH policies or adding skips. Fresh local evidence after integration includes: | Scope | Target | Passed | Skipped | |---|---|---:|---:| | Client lifecycle / channel ownership / builder fixtures | net10.0 and net48, each | 96 / 103 / 123 | 0 | | Combined server lifecycle, events, aggregates, crypto, and contracts | net48 | 358 | 0 | | Full lifecycle plus certificate-alarm and aggregate fixtures | net10.0 | 116 | 0 | | Final server-contract and history-routing delta | net10.0 and net48, each | 84 | 0 | | Subscription / XRegistry / WoT event regressions | net10.0 | 7 / 2 / 3 | 0 | | Full Sessions project | net10.0 | 780 | 379 | | Full ComplexTypes project / downlevel resolver fixtures | net10.0 / net48 | 2854 / 15 | 0 | | Full WoT project / downlevel structured-write fixtures | net10.0 / net48 | 1496 / 27 | 0 | | TLS domain-name regressions | net10.0 and net48, each | 21 | 0 | All listed runs exited 0. The Sessions skips come from existing endpoint and policy capability guards; they are not counted as passes. No skip was added. Worker validation also covered full DI (426 passes), full History (540 passes, 21 existing skips), 38 exact downlevel event/history failures, and 60 repeated certificate-rotation race cases. The final crypto fixtures passed 73 cases on each target with the unchanged leak detector; a temporary premature-disposal mutation made all three borrower tests fail and was then removed. All 29 C# files in this follow-up pass included-file formatting at info severity across 12 projects. The complete PR interface audit now covers 54 interfaces and 271 members with zero missing contracts or line-width findings. No full-solution or NativeAOT matrix is claimed. New-head CI has started and remains authoritative for the remote result. ## Test-result gate follow-up at `4b6e1203a` Azure build 18401 reported the net48 Client job as successful despite a test-host crash after only 264 passing tests. Its old evaluator counted per-test failures but ignored the failed run verdict. This was a partial run, not a benign exit after the suite had completed. The shared result evaluator now rejects aborted, errored, incomplete, malformed, or inconsistent TRX reports. Each file must describe a completed run, so a passing file cannot mask another file's failure. It retains support for completed runs followed by a benign nonzero host exit, existing skipped-result conventions, and no-TRX MTP jobs. All 78 regression cases pass after integration using Windows PowerShell 5.1. Real completed Sessions and Client reports also pass. The process-test fixture follows the existing NET10_0-only tools-test pattern; its net48 build is not counted as a test run. Formatting passes for the added test file. The Client host crash itself has not reproduced locally. The isolated fixture passed 59 tests, and two fresh full fast-CI selections each completed with 2,392 passes and three existing skips, including a run with crash collection enabled. The CI merge tree is identical to the tested source tree. No speculative runtime change was made, and the original partial CI run is not claimed as a full-suite pass. Azure build 18402 has now completed the full net48 Client run: 2,392 passed, three existing console skips, and a successful test-host exit. The corrected evaluator independently validated outcome=Completed. Across the matrix, 119 test-project jobs succeeded; Sessions net10.0 was canceled when the remote provider deprovisioned its runner, so the overall Azure pipeline was canceled. That cancellation is not claimed as a code failure or a successful run. CodeQL and three Docker image jobs were still running at the latest check. The migration discovery failure remains separate. ## Documentation follow-up at `57ed02bea` The environment blocker has been removed by the maintainer. The three bundled migration references now exactly match the canonical documents after deterministic link rewriting; all 15 bundled documents pass `validate-migration-plugin.ps1`. The canonical migration prose was not rewritten. `FileSystemClient.md` now documents that extended Windows roots preserve literal trailing-dot names, completing the filesystem review follow-up. The filesystem thread has been replied to and resolved after publication. The review pass now has 108 of 110 threads resolved. The two explanation-only threads remain open as requested; no unfinished change request is being represented as resolved. ## Cross-platform follow-up at `0d9d936a8` With migration discovery restored, the Linux and macOS test matrix exposed two stale durable-subscription expectations. The expected value 83,442 encoded the old 32-bit overflow when converting 3,600 hours to milliseconds. The existing overflow-safe server correctly returns 14,400,000 lifetime intervals at a 900 ms publishing interval. Only those two expected constants changed; production behavior, negotiated-hour checks, and all other assertions remain unchanged. The exact local lifetime selection reproduced both failures before the correction. The full durable suite now passes 36 cases with 11 existing skips on each of net10.0 and net48. All four lifetime cases executed and passed on both targets, and included-file info-severity formatting passes. ## Session shutdown follow-up at `8daf7f091` A late net48 Sessions failure exposed a shutdown race. Canceling an in-flight keepalive read can produce a transport `ServiceResultException`. The retiring worker treated its own cancellation as proof that the peer was unavailable, so `CloseAsync` or `DisposeAsync` could skip the server-side `CloseSession` request. The worker now ignores that service error only when its own token is canceled; genuine peer errors still update liveness. The full integration fixture reproduced the original error-code mismatch. Four deterministic mock-transport cases then produced three failures and one passing genuine-error control before the fix. They verify successful close, returned server error, asynchronous disposal, and unchanged behavior for a real keepalive failure. Fresh related runs pass 75 client and 101 integration cases on each of net48 and net10.0, with no skips. Ten repetitions of the formerly flaky full net48 fixture pass all 1,010 cases. All three changed files pass info-severity formatting, and temporary diagnostic instrumentation was removed. ## Atomic listener snapshot follow-up at `82dc22b5d` Ubuntu Core CI exposed an unsafe formatter rewrite in TCP listener disposal: `ConcurrentDictionary.ToArray()` had become a collection spread. A concurrent channel removal between the spread's count and copy operations could leave a default entry, causing a null dereference during disposal. The listener now uses the dictionary's atomic `Values` snapshot and disposes those channels outside the listener lock. Deterministic regressions close zero, one, or all channels at the copy boundary. Before the fix, the one/all-removal cases reproduced the exact null dereference; the unchanged-count control passed. All 23 admission/listener cases now pass on net10.0 and net48, and the full fast Core net10.0 suite passes 5,267 cases with 88 existing platform skips. Both changed files pass info-severity formatting. A bounded audit of the formatter's other snapshot rewrites found no further verified unsafe concurrent-registry copies. ## Shutdown-test observation follow-up at `58403ee8b` The net48 shutdown-order test raced its own observation: it read `m_publishWorkerTask` after starting shutdown, which can legitimately drain the worker and clear that field immediately. The test now captures the worker before shutdown starts and confirms it is initially running. It still requires the worker to finish while shutdown remains blocked by the held manager semaphore. Production behavior is unchanged. A temporary scheduling perturbation reproduced the exact null-field failure. The corrected capture passed 100 perturbed iterations; both the temporary repeat and yield were then removed. The final 126 subscription/lifecycle cases pass on each of net48 and net10.0, and formatting passes. A complete local Sessions net10.0 run also passed 780 cases with 379 existing capability skips in 7m20s after the earlier keepalive correction. ## Retirement and alias-startup follow-up at `1a048ff39` The shadow-generation test now observes its documented asynchronous cleanup through the existing bounded helper. Removing the replacement does not join a background drain that already claimed the retired generation. The test still checks live-registration removal immediately and requires the old node to disappear; no timeout or production lifecycle behavior changed. All 81 lifecycle cases pass on each of net10.0 and net48. Initial alias-node materialization now retries one timed-out, read-only snapshot query before creating nodes for that root. The retry is logged through source-generated logging. Each query retains the original shared 100 ms deadline; repeated timeouts, other errors, and cancellation still abort startup. Client searches and live refresh do not gain this immediate retry. Fault-injection tests cover success after one timeout, a persistent timeout, a different store failure, and cancellation. All 187 related alias/hosting cases and the original certificate-rotation integration case pass on each target; the positive test records exactly one retry warning. The alias documentation now accurately describes the shared request budget. All changed C# files pass formatter checks, and the complete 54-interface/271-member documentation audit passes. Fresh CI is running on `1a048ff39`; the previous completed matrix exposed only the two failures corrected in this batch and their dependent summaries. ## Sample endpoint allocation follow-up at `d08a94925` The strong-cluster test harness allocated OPC UA and Raft endpoints in separate released-port batches. Uniqueness was enforced only inside each batch, so the same OS-assigned port could appear in both protocol groups. The harness now requests one distinct batch for both groups and splits it before launching any replicas. Deterministic one- and three-replica allocation cases reproduced overlapping groups with the old plan and pass with the corrected plan. The complete 17-case short-haul sample suite passes without skips; all failover, historian-continuation, and service assertions remain unchanged. Both changed files pass info-severity formatting. This prevents intra-cluster self-collisions but does not claim to reserve released ports against unrelated external processes. ## Code-review follow-up at `085fd9636` A review of the complete branch diff found five defects this PR introduced. All are now fixed, each in its own commit. `RelatedTo`'s recursive-to-iterative rewrite defaulted the optional `includeTypeDefinitionSubtypes` and `includeReferenceTypeSubtypes` operands to `false`. Part 4 §7.7.4 specifies both default to `true`, so a filter that omitted them silently stopped matching subtypes. Dynamically created key-credential nodes derived their namespace from the containing folder, which is the standard `i=18155` node in namespace 0 — the namespace reserved for the OPC UA standard address space; they now resolve the server-owned namespace and fail with `BadInternalError` rather than guessing index 1. The retained audience-less `CreateTokenData` overload produced tokens that verification always rejects, so it is now `[Obsolete]` and throws instead. A failed reference to a remote parent left the new node registered with a one-sided inverse reference, and is now rolled back. An existing `.pfx` is restricted before it is rewritten, rather than after its new key bytes are on disk. One further reported finding was rejected after investigation. `JwksIssuerKeyResolver` deliberately does not dispose retired key snapshots: `RetiredKeysAreCollectibleWhileResolverRemainsAliveAsync` proves the resolver retains no retired snapshot, and `ReturnedKeysSurviveRepeatedRefreshAndResolverDisposalAsync` requires already-returned keys to keep verifying across refreshes and resolver disposal. Adding disposal would have broken that tested contract, so the exploratory change was reverted. Validated on net10.0 and net48: 256 Core and 633 Server cases pass, with one pre-existing net48 skip. The build reports zero compiler and analyzer diagnostics, all eight included-file info-format checks pass, the contract audit covers 58 interfaces and 310 members with no findings, and the 15 bundled migration documents validate. All 122 review threads are resolved; the key-credential namespace thread was reopened to retract an earlier incorrect answer and then resolved against the real fix. ## Review-body follow-up at `da0d59cfb` The re-review at `8daf7f091 + 82dc22b5d` listed four items in its summary that had no inline thread of their own, so they had not been picked up. All four are now fixed. Both event-dispatch permission gates had been tightened from not-Bad to `IsGood`, which silently dropped events whose permission verdict is Uncertain; the data-change path in the same file still treated Uncertain as deliverable, so the two had diverged. `EventSourceRegistry` only cleared `ConsecutiveFailures` when a source was deactivated, so a source that had backed off to the 30-second cap kept that delay for the rest of the process even after starting successfully. `UserNameIdentityTokenHandler` built a temporary issuer chain whose `Add` calls take independent certificate references, and never released them. The fourth was the receiver-side sequence rollover, which the reviewer had correctly re-flagged as still open despite its thread being resolved. `m_sequenceRollover` was set permanently, so the second legal wrap on a long-lived channel was rejected and faulted the channel along with the transport-reconnect OPN. OPC 10000-6 does not cap a SecureChannel at one wrap. The flag is now cleared once an accepted number has traversed the normal range, which keeps rejecting a replayed low number that never left the rollover window. Validated on net10.0 and net48: 636 / 593 Core cases and 135 / 134 Server cases pass, including the new `UaSCBinaryChannelSequenceRolloverTests` and the Uncertain-permission delivery cases. The build reports zero compiler and analyzer diagnostics and the changed files pass included-file info-format checks on both targets. The previous head `085fd9636` was fully green: 279 checks passed and Azure build 18414 succeeded with 137 of 137 jobs, after the platform automatically retried a job whose NuGet tool download had hit a transient TLS error. ## Reported issues #4508 and #4509 at `6ad1ecf16` **#4508 (V2 subscription recreate deadlocks against a faulted transport) was not yet fixed and is now closed by `bac260a06`.** Both drain sites the report identifies were still unbounded. A publish worker that started its request before the quiesce parks inside the service call on the channel ready gate while holding an active publish request; the recreate that would make the channel ready is the very operation awaiting the drain, so the wait never ends. The drain now cancels in-flight attempts through a per-attempt token linked to the worker token. An aborted worker rolls its acknowledgements back, releases the request and returns to the paused park instead of terminating, so it resumes when the caller leaves the quiesce. Publish ingress stays quiesced for the caller's operation, so `DropPendingForSubscription` keeps the guarantee the report asks to preserve and no blind timeout is added. The new regression parks a worker on a cancellable gate that never completes on its own: it reproduces the hang for the full 30-second budget before the change and passes after it. **#4509 (identity provider fails the initial connect) was already fixed for its primary symptom.** `HandleConnectAsync` materializes the provider's identity through `CreateIdentitySelectionContext` before the first `CreateAsync`, so Anonymous is no longer substituted against a UserName-only endpoint. `6ad1ecf16` adds the two remaining details from the report: the enabled-policy set now includes the negotiated channel policy, so a client cannot reject the policy it already accepted as `NotEnabledByClient`; and when discovery has not populated the endpoint's token policies the connect keeps the configured identity so the attempt fails at the transport layer for the reconnect policy to retry, instead of failing at the identity layer. Validated on net10.0 and net48: 477 / 473 client session and subscription cases pass, the build is free of compiler and analyzer diagnostics, and the changed files pass included-file info-format checks on both targets. The full `Opc.Ua.Sessions.Tests` suite also passes locally on net10.0 with 782 passed and 379 pre-existing capability skips. GitHub checks are green on this head: Build and Test .NET 10.0, Docker Sample Images CI, and NuGet Publish all succeeded. Azure build 18417 completed 134 of its 135 jobs successfully; its net10.0 Sessions job was cancelled by the hosted-agent provider ("Received request to deprovision"), the same infrastructure flake that hit build 18409 earlier on a head predating these changes. That job is not claimed as passing, and the local full-suite run above covers the same project. The previous head `da0d59cfb` completed Azure build 18415 with every job succeeded. ## Review follow-up at `a08f0c12b` Eleven new review threads arrived, nearly all documentation. Before acting on each "this is new in 2.0" remark I checked the API against `master378` rather than assuming, because a genuine 1.5 API still needs its migration entry. `ManagedSession`'s server-redundancy refresh had two hard-coded two-second bounds. The new `ServerRedundancyOptions` exposes `RefreshTimeout` for the metadata read and `PeerDiscoveryTimeout` for each peer lookup, defaults both to the previous two seconds, validates that a bound is positive or `Timeout.InfiniteTimeSpan`, and flows through `ManagedSessionOptions`, `ManagedSession.CreateAsync`, the fluent builder, and `DefaultServerRedundancyHandler`. `AsyncCustomNodeManager` and `KeyCredentialBridgeAuthenticator` are both absent from `master378`, so their obsolete members had no compatibility constraint and are removed rather than carried: `AsyncCustomNodeManager.ReadInitialValue`, the audience-less `CreateTokenData` that only threw, and the audience-less `CreateProof` that produced a proof no server accepts. `CustomNodeManager2.ReadInitialValue` and the `MonitoredNode2` migration section are genuine 1.5 APIs and are untouched. The documentation now states master's behaviour instead of the delta from 1.5.378, with each moved item already covered under `docs/migrate/2.0.x/`. `IHistorianAnnotationProvider` is described by its annotation-time key rather than as "legacy" — it is new in 2.0, so the label implied a compatibility constraint that does not exist. The KeyCredential bridge payload's `"version"` field is explained as a vendor-extension format version with no OPC UA counterpart, and its version-1 upgrade narrative is gone. `CertificateManager.md`'s migration walkthrough is replaced by the resolver API it targets. `NodeManagers.md`, `Sessions.md`, `AsyncServerSupport.md`, `Certificates.md`, and `Profiles.md` no longer announce features relative to 1.5. `Benchmarks.md`, `WhatsNewIn2.0.md`, `DeveloperGuide.md`, and `docs/migrate/` keep their 1.5.378 references, which are their subject. CI then exposed a defect this batch introduced: five fixtures resolve `ManagedSession`'s private constructor by its exact positional parameter types, so the added parameter compiled cleanly but made `GetConstructor` return `null` at run time. `7df1d5c40` updates every site; `Redundancy.Client` passes 126 of 126 and the affected client fixtures 112 of 112. The BouncyCastle question is answered and tracked in #4510: `Opc.Ua.Core` already project-references `Opc.Ua.Security.Certificates`, which already carries the conditional BouncyCastle reference, so the raw-ECDH polyfill belongs there rather than as a new Core dependency. The `IUserDatabase` metadata question is addressed to another maintainer and is deliberately left open. ## Reported issue #4509 follow-up at `5d4d13d63` The reporter verified `6ad1ecf16` and found one case still failing, correctly. The empty-token-policies branch kept the configured identity so a server that is down surfaces a transport failure rather than an identity error. A provider-only configuration has no configured identity, so it kept `null`: `OpenCoreAsync` turned that into Anonymous and `OpenValidateIdentity` rejected it with `BadIdentityTokenInvalid`, silently ignoring the configured provider. The branch now requires a configured identity to defer to. Without one the provider is consulted, so its own `BadIdentityTokenRejected` names the offered and rejected policy set instead. Two regression tests cover both configurations; the first fails against the previous behaviour by reaching the session factory with a `null` identity, which is the exact step that produced the reported error. That branch had shipped without a test, which is why the case was missed. ## Review and CI status at `5d4d13d63` **All actionable review threads are resolved: 132 of 133.** The single open thread is a question the reviewer addressed to another maintainer about moving user metadata into `IUserDatabase`; it is left open for them rather than resolved silently. Every resolved thread carries a reply naming its fix commit. **Latest-head CI is green on `5d4d13d63`: 279 checks passed, zero failed, zero pending**, with one conditional signed-package publishing job skipped. Local validation for this batch: the full `Opc.Ua.Client.Tests` suite passes 2,430 of 2,430 on net10.0, `Opc.Ua.Redundancy.Client.Tests` 126 of 126, and `Opc.Ua.Server.Tests` 590 of 590 for the affected selections. Both net10.0 and net48 build clean for `Opc.Ua.Client`, `Opc.Ua.Server`, and the changed test projects, and all changed files pass included-file info-severity formatting on both targets. The PR remains open; no merge was performed. As stated at the top, this does not claim that every item in the 244-finding audit backlog is complete. ## Latest CI follow-up at `b6f2dfa43` Azure build 18442 exposed a net48 compile regression in the Kafka adapter: `RuntimeHelpers.GetUninitializedObject` is unavailable on .NET Framework. Commit `2cf1e0eed` now uses normal `ProducerMessage` construction on `NETFRAMEWORK` while retaining reflection-based construction for modern targets that can load a different Dekaf runtime asset. The exact net48 CI selection passes 92 of 92 tests, and the netstandard2.1 adapter guard selection passes 11 of 11. After merging the latest `master`, GitHub Actions run 35643592139 is green. The initial Ubuntu Core.Schema job built successfully and passed 160 of 160 tests, then hit an external 403 while finalizing its test-result artifact; its failed-job rerun completed successfully. Azure build 18451 was canceled when its remote provider deprovisioned the net10.0 Sessions runner (`Received request to deprovision: The request was cancelled by the remote provider`). Azure attached no test task log or source error, and the canceled parent left that child check stale as in-progress. No source workaround, test skip, or check relaxation was made for either infrastructure failure. --------- Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> Copilot-Session: 68f26810-22b8-476f-abcd-0a8c82d6e208 |

Fix hosted-server DI composition gaps (#4456)
# Description Complete the remaining hosted-server DI hooks so applications can compose the regular server without subclassing `StandardServer` solely for these extension points. - Add `ConfigureServerProperties` and ordered, per-server `ConfigureResources` callbacks. BuildInfo defaults come from the effective application configuration; explicit property registrations take precedence without mutating shared options. - Add authenticator instance/validator-aware factory overloads and generic/async-delegate startup tasks. Startup tasks are awaited in registration order, and failures or cancellation clean up the server. Host shutdown waits for execution cleanup before disposing injected dependencies, including when its shutdown deadline expires. - Add asynchronous and legacy node-manager factory instances plus deferred, configuration-aware `ArrayOf<IAsyncNodeManagerFactory>` registrations. Resolve factories after configuration and certificate setup while preserving ownership and feature isolation. - Register alias stores before address-space creation and add opt-in standard `TagVariables`/`Topics` materialization. Existing custom-category behavior is retained; browse nodes are startup snapshots while queries and supported LastChange values remain live. - Derive the default DI server from `ReverseConnectServer`, retaining DI roles/session hooks and authoritative XML/stream configuration. Ignore queued callbacks from stopped or superseded timers to prevent reconnection or rearming after shutdown. - Fix resource translation lookup/formatting exposed by the new callbacks, retain existing constructor signatures and direct/custom-server paths, and document the optional hosting APIs. Adopting these hooks is optional; existing construction and subclass-based customization remain supported. The migration guide is unchanged. No changes to UA-.NETStandard-Samples and no new dependencies. ## Related Issues - Fixes #4410 ## Validation - Focused server hosting, aliases, reverse-connect, configuration, and resource suites: **571 passed on net10.0 and 571 passed on net48**. - Existing affected real-session alias integration fixtures: **11 passed on each framework**. - Real reverse-connect discovery, session creation, and BuildInfo reads verified for options, XML-file, and stream configuration. - Published and executed the Windows NativeAOT test binary: **7 HostingAotTests passed**. - Final server-library build passed across all configured target frameworks with **0 warnings and 0 errors**; no new diagnostics in changed test files. - Focused changed-line coverage: **336/338 executable production lines (99.41%)**. - Deterministic timer regressions failed before the shutdown fix and pass afterward. - CI shutdown follow-up: the unchanged `UnavailableUpstreamEndpointFailsMappedReadAsync` scenario passes locally, and **245 hosting tests pass on each of net10.0 and net48**, including regressions for an expired host shutdown deadline and already-canceled startup. The local net48 run uses a short NUnit work directory to avoid Windows path-length limits. ## Azure build 18136 follow-up - Await WoT browse reconciliation before upload, default-version, and enable/disable handlers return. Three barrier-controlled regressions reproduce the exact missing version metadata before the fix. - Make the reconciliation test observe the actual corrective state frame rather than require a new acknowledgement after a no-op reseed. The corrected tests also verify value, status, timestamp, and quiescence; production gossip behavior is unchanged. - Drain redirected stdout/stderr when sample processes exit, replacing a fixed grace delay that could lose the final success line. A controlled real-process regression fails before the fix. - Fix CA1508, CA1823, CA1850, CA2012, and CA1861 at their sources, and correct unsupported legacy AOT declarations and the existing stress-placeholder target. Modern test targets and AOT analysis remain enabled. Follow-up validation: - Full **Release `UA.slnx` builds pass on net10.0 and net48 with 0 warnings and 0 errors**. - Complete previously failing WoT net48 job: **1496 passed**. The identical binary was run from a short local assembly path to avoid the nested repair worktree exceeding Windows path-length limits. - Complete previously failing Redundancy.Server net10.0 job: **783 passed**. - All short-haul HA/process cases: **12 passed**, including both original identity-failover topologies. - Affected WoT lifecycle selection: **113 passed on Release net10.0**; controlled replication selection: **15 passed on each framework**. - No test assertions, timeouts, coverage thresholds, collector settings, or CI failure gates were weakened. Existing legacy empty-project result notices and auto-property coverage exclusions remain unchanged. These are full solution builds plus the reported test scopes, not a full local `UA.slnx` test run. Remote validation at `77c1055f1adb1557c5bf99b70e76f4a0cd95ee94`: **all 265 PR checks passed**, including Azure build **18172**, GitHub Build and Test, CodeQL, and Docker image checks. ## 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. --------- Co-authored-by: romanett <romanett98@gmail.com> Co-authored-by: Copilot Autofix powered by AI <175728472+Copilot@users.noreply.github.com> |

Harden HA address-space hydration and replica-consistent NodeIds (#4445)
# Description Follow-up to #4390 for distributed address-space ownership, authoritative hydration, and replica-consistent wire NodeIds. Tracks #4444. Identity implementation: `a78d59067` (Server policy/lifecycle/adapter seam) and `07faf5cfd` (replica identity module, runtime wiring, examples and proofs). ## Replica identity - `UseReplicaNodeIdentity` / `ReplicaNodeIdFactory` reserve fixed shared namespace indexes before node-manager construction and reuse `DefaultNodeIdFactory`. ApplicationUri and built-in diagnostics/configuration remain local. - Replicated startup requires an explicit identity contract. Namespace layout, deterministic mode, replica-set identity and writer policy must agree. Standard factory views, replacement and registration preserve the policy. - Active/passive writer-assigned identities are replicated unchanged. Independent creation requires stable keys or explicit IDs. Live IDs and retained tombstones are reserved before writer allocation; no network/storage call runs in `New`. - Protected store descriptors use strong routing, including customized hybrid prefixes. Unknown legacy state and empty eventual scans cannot authorize automatic adoption. Verified-new hybrid provisioning is explicit. - Active/active frames compare the descriptor before CRDT merge. Rejected frames are not reported as applied; incompatible admission remains at ServiceLevel 0 through the standard service-level wiring. - Shared metadata validation covers type definitions, data types, references, permissions, NodeId/ExpandedNodeId/QualifiedName values, arrays/matrices, DataValues and encodeable structures/arguments, without reflection. - Runtime preparation hydrates retained IDs before replacement routes publish. Rebinding keeps the existing store/election or gossip transport/map and attaches to the new node-manager sources. Normal node-manager mutations, including AddNodes, reach the cached local-address-space adapter. - WoT materialization retains the stable configured factory. Samples expose genuinely factory-created nodes and a client `--identity` failover workflow. ## Preserved HA repairs The published `d99995003` and `79da74f14` fixes remain in place: - Shared linearizable sequence/lease coordination; no pretend CAS on CRDT and no private counter substituted for shared coordination. - Strict authoritative record decoding, protected pending reservations, safe snapshot publication and required delta retention. - Accepted topology state controls authoritative membership; stale deletion cannot remove a newer incarnation. - Independent subtree attachment tracking and correct disposal of the final snapshot task. - Values wait for their topology, and parent tombstone horizons prevent older descendant values crossing incarnations. A new deterministic regression also covers writer hydration preparation: temporary reconciliation removals must remain inbound application, not be recaptured as new shared deletion records. ## Validation ### Review feedback fixes `3a682155b` addresses the active-node notification, WoT namespace-index bounds, and retired-manager XML documentation feedback. The address-space adapter now notifies listeners with the registered active node, and both WoT managers reject missing/out-of-range namespace indexes before ownership is established. Targeted feedback validation passes on net10.0 and net48: 8 address-space adapter cases and 74 WoT cases per framework, plus 17 hydration/gossip/live-client integration cases on net10.0. The wrong-instance notification and missing namespace regressions were reproduced before the fixes. ### Identity implementation evidence | Selected scope | net10.0 | net48 | | --- | --- | --- | | HA repair, identity, metadata, peer admission and real-client identity/reload fixtures | 215 passed | 215 passed | | Factory, fluent authoring/import, NodeManagement and address-space adapter fixtures | 213 passed | 213 passed | | WoT node-manager fixtures | 68 passed | 68 passed | - Real UA-TCP clients compare full NodeIds/reference targets across independent servers in all four deterministic modes, with different manager/creation order and local allocations. Saved IDs work after endpoint failover and restart. - Real AddNodes-created IDs remain readable through successive live manager replacements in both replication modes, including nodes created after a reload. - Two process-level cases start three sample replicas, kill the serving process, verify a different serving ServerArray URI, and reuse cached factory-generated IDs for Read and CreateMonitoredItems without remapping or rebrowsing. - The identity/hydration scenario runs from the actual published win-x64 NativeAOT executable in the existing historian companion host. - The focused writer-recapture regression was observed failing without its fix, then passing. The real reload scenario was additionally repeated while diagnosing that race. - Changed-file formatting/style/analyzers were applied. Existing CA1508, CA1823, CA1861 and CA1850 warnings in untouched upstream files were not suppressed. The selected checks above do not replace full-solution CI, coverage gates or maintainer review, and do not claim that the entire solution or every native platform was run. #4444 remains the tracking issue. ## Contract and consistency limits Fixed identity does not make eventual payload reads linearizable. Hybrid views remain non-destructive, use explicit tombstones, and do not infer empty-store bootstrap or partition completion from absence. Compacted snapshots require authoritative storage. Failed/uncertain reservations require reconciliation. There is no automatic namespace-slot allocation, persistent logical-key mapping database, live renumbering, legacy-store wipe/adoption, or new hash algorithm. Opaque shared structures require a registered codec so their namespace-bearing fields can be validated. Application callbacks are still application-owned. ## Related issues - Tracks #4444. - Follow-up to #4390. - Builds on the merged NodeId factory (#4433), configure/seal (#4442) and lifecycle/import (#4427) integration at `aedd3f738`. ## Checklist - [ ] I have signed the CLA and read CONTRIBUTING. - [x] Added targeted regression and integration tests. - [x] Updated directly related API, HA, migration and sample documentation. - [x] Ran scoped formatting and the targeted framework checks listed above. - [ ] Full UA.slnx matrix and coverage gates completed. - [ ] All CI and maintainer review completed. --------- Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> Copilot-Session: 9dbd9527-d818-47a0-984c-fbb1472d3d6b |

Add native xRegistry events and distinct Resource versions (#4396)
## Summary - support the xRegistry 0.6.0 distinct Resource/Version hierarchy: `Registry -> Group -> Resource -> Versions -> Version` - instantiate stable logical Resource nodes separately from exact Version nodes while preserving existing Version NodeIds - delegate logical Resource FileType operations and Version-view metadata to the selected default Version with handle pinning and shared writer reservations - make Resource and Version delete behavior role-stable and use `MetaEpoch` / `Epoch` respectively - use stable Resource SourceNodes, exact Version SourceNodes and the `Server -> Registry -> Group -> Resource -> Version` notifier chain - keep a model-metadata-gated client fallback for 0.5 flat Servers; 0.6 Servers expose no legacy aliases - target `HasWoTProjection` at the real stable logical Resource node - use `AsyncCustomNodeManager` for the registration, fast-path, and federation managers, with awaited lifecycle, node mutations, event delivery, and cleanup - handle startup rollback, reentrant deletion callbacks, undisclosed file handles, and retryable cleanup without blocking unrelated file operations ## Authoritative dependencies - companion specification: OPCF-Members/spec-drafts#32 at `d3399fca025025a73e5a6b599f850a81d985c060` - OPC UA binding: xregistry/spec#568 - xRegistry event semantics: xregistry/spec#563, merged as `66ee31e47fbadff6ab982ae1516f7d9065e46b64` - companion NodeSet SHA-256: `369f5f3f1814b333e4eeb52bfb4b6a730cdff372505a5f91a54c94f0016ac4cf` ## Review feedback - keep the WoT Connectivity information-model designation at `1.1`; draft revisions update the publication date without changing the model version - eliminate all 198 unique CA1861 diagnostics across 54 files and remove seven obsolete project suppressions - fix the analyzer-clean touched-path CA1307 and the hierarchy follow-up CA1846/CA1851 diagnostics without dropping legacy-TFM compatibility - recover the reconcile queue after callback faults/cancellation and continue accepted pending changes - remove migration guidance for the xRegistry managers, which are new in 2.0 ## Compatibility - public WoT Connectivity model designation remains `1.1` - generated event-record ABI, constructors, options, NodeIds, and stored documents remain compatible - the generic xRegistry managers are new in 2.0 and implement `IAsyncNodeManager`; use `IAsyncNodeManagerFactory` and the async lifecycle hooks (see `docs\XRegistry.md`) - persistence schema and document blobs remain compatible unless noted below ## Validation - merge validation at `980422f76` with upstream `e8bec27d5`: 454 targeted WoT/materialization/model/registry cases and all 327 XRegistry cases passed on both net10.0 and net48; all 29 net10 aggregation sample cases passed - feedback regressions at `308e8ba74`: 55 targeted queue and live registry event/projection/lifecycle cases passed on each of net10.0 and net48 - prior CI: all 266 checks passed at `6489a0908`; the unchanged Ubuntu Core certificate-counter test and dependent jobs passed on the one-time retry ([run 34117304035, attempt 2](https://github.com/OPCFoundation/UA-.NETStandard/actions/runs/34117304035/attempts/2)) - `Opc.Ua.XRegistry.Tests` — 327 passed on net10.0 and net48 for migration commit `32c914aaf` - `Opc.Ua.WotCon.Tests` net10.0 — 1348 passed - `Opc.Ua.WotCon.Bindings.Tests` net10.0 — 683 passed - `Opc.Ua.SourceGeneration.Core.Tests` net10.0 — 3807 passed, 8 skipped - `Opc.Ua.SourceGeneration.Tests` net10.0 — 145 passed - `Opc.Ua.SourceGeneration.Stack.Tests` net10.0 — 94 passed - affected XRegistry and WoT client/server projects build successfully - xRegistry NodeSet is byte-identical to the companion artifact - repository-wide CA1861 inventory — 198 unique diagnostics across 54 files reduced to zero - targeted changed-fixture validation — 1,098 passed, 3 skipped, 0 failed - constrained full `UA.slnx` net10.0 Release build — CA1861 = 0 - `Opc.Ua.XRegistry.Client` net472 and netstandard2.1 builds — 0 warnings, 0 errors - independent shared-array safety review — no significant issues - `git diff --check` The final review regressions cover concurrent reconcile/open, synthetic logical handle collisions across default switches, cross-session Close isolation, shared writer reservations, logical FileType property/change propagation, logical Labels delegation, role-fixed deletion, event sources, model-version gating, and stable `HasWoTProjection` targets. The companion specification and protocol binding are reviewed in the linked PRs above. --------- Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> Copilot-Session: 5c79a1ed-6dab-4522-a9fc-6548caa78ad5 Copilot-Session: b605797f-a97a-4cd0-8f12-016d33c2fd88 Copilot-Session: 7ef369a5-2307-4f71-8a11-15af0e72f240 Copilot-Session: e716d455-8397-4d22-9c5a-398847ab7317 |

Complete WoT binding preservation and two-pump aggregation (#4431)
# Description
Complete WoT Binding preservation and the two-pump aggregation workflow
without implicit overlays or multi-source action fan-out.
- Add verified linked-document export and bounded partition merging.
Preserve complete source facts, reject contradictory archival content,
and retain usable readable content when a future native grammar is
unsupported.
- Wire local Methods and Condition events through the existing
injectable binding/runtime infrastructure. Keep local and upstream
identities distinct, translate namespace-bearing values, and bound
occurrence routes by source and generation.
- Wait for asynchronous event-producer readiness before completing
subscription creation, so the first alarm is not lost. Preserve
cancellation, teardown, and startup-failure reporting.
- Import runtime types in inheritance order and attach typed Method
argument Properties. Keep generated Double spelling deterministic across
supported frameworks and remove an AOT-unsafe registry validation
conversion.
- Generate both pumps and their asset/group projections. Expose fifteen
typed readings per pump, separate source-owned controls, and
acknowledge/confirm/reset workflows. Extend the demo script for managed
and NativeAOT execution, bounded failures, and exact-process cleanup.
- Synchronize current-state documentation and specification fixtures.
Compose fixture paths from platform-independent components and emit/pin
LF pump XML so byte-exact regeneration holds on Windows, Linux, and
macOS.
- Keep sample JSON readable with sorted members, two-space indentation,
and LF line endings. Normalize generated filenames to single hyphens
without changing registry resource IDs, document values, logical links,
or dependency ordering; the manifest maps resource IDs to their physical
filenames.
Most changed files are deterministic regenerations of checked-in sample
documents. The demo manifest contains 533 linked resources; the
aggregation server remains generic and has no Pump-specific compiled
model dependency.
No new alarm vocabulary, shelving/suppression/dialog/ConditionRefresh
transport mapping, Azure SDK changes, or complete Pump/OpenUSD parity is
introduced.
## Related Issues
Fixes #4430, which records the approved implementation scope, design
decisions, and acceptance criteria.
Follow-up to #4411. Specification fixtures are pinned to

- .NET 10 and .NET 8: complete affected converter/schema, WoT
Connectivity, and binding suites passed.
- .NET Framework 4.8: affected libraries, converter/generator, projected
runtime, readiness, and NodeSet-import compatibility runs passed. The
existing filesystem test exceeding the host's legacy path limit passed
through a temporary short-path alias, without changing its assertions.
- All 29 aggregation sample tests passed, including the independent
companion-model oracle.
- Managed/default-port and NativeAOT/alternate-port demo runs completed
with 533 documents, two pumps, thirty Good readings, and all four
pump/source control and alarm workflows.
- Timeout and duplicate-port failure paths were exercised; owned
processes and ports were released.
- Specification artifact/rule checks, byte-identical example mirroring,

Complete WoT Binding 1.1 alignment and conformance coverage (#4411)
# Description Completes the UA-.NETStandard implementation of the final OPC UA WoT Binding 1.1 semantics and aligns the WoT Connectivity 1.1 model with xRegistry 0.4.0. The change: - retires `uav:isEvent` and `uav:severity` from current Binding output while preserving unknown members through the generic converter's ordinary residue mechanism; - removes `uav:severity` from the asset Thing Description parser and materializer, so document metadata cannot set occurrence severity; - implements logical EventType definitions, ordered resolution providers, explicit/default selection precedence, materialized member paths, and the built-in `BaseEventType` fallback; - adds deterministic portable identity and browse-path anchoring; - populates bound type declarations instead of creating duplicate siblings, including inherited and closed-content validation; - resolves and validates `uav:externalSchema` without overriding authoritative DataType definitions; - hardens DataType dimensions, native projections, preservation envelopes, URI transmission, projection limits, and delete-policy handling; - synchronizes the xRegistry and WoT Connectivity source-generation inputs; - pins all 27 specification examples, all 97 implementation-owned normative requirements, and all 12 cross-language vector groups to the final specification revision; - adds `samples/WotCon/run-aggregation-demo.ps1` for a verified one-command aggregation client/server round trip and replaces the README topology sketch with Mermaid; - normalizes redirected PowerShell diagnostic presentation in the statement-digest test harness so its semantic assertions are stable on Windows, Linux, and macOS. WoT Connectivity remains model version `1.1`; draft iterations are identified by release labels such as `1.1-draft5`. **Specification dependency:** the evidence assets pin `OPCF-Members/spec-drafts` `main` commit `25db507121b503fd31c8816fbfae67a6822e813b`. The corresponding specification follow-up is `OPCF-Members/spec-drafts#35`. ## Validation - Latest GitHub/Azure CI: 266/266 checks passed. - .NET 10 feedback-focused tests: - WoT Connectivity event/model/traceability: 72 passed - binding capability/traceability: 8 passed - coverage-gate tests: 25 passed - Complete .NET 10 Tools project: 752 passed, 1 intentionally skipped. - .NET Framework 4.8: - WoT Connectivity event/model/traceability: 72 passed - WotCon bindings build: 0 warnings, 0 errors - NativeAOT build: 0 warnings, 0 errors. - WoT aggregation demo: 16 documents uploaded and all 10 mapped values read with Good status; exact processes and isolated PKI stores cleaned up. - Specification traceability: 402 normative statements mapped; all 97 implementation-owned statements have passing test evidence with zero gaps. - Shared conformance vectors: 12/12 groups execute. - Final CI coverage: - project line coverage: 86.83% (floor 70%) - project branch coverage: 76.71% (floor 60%) - patch coverage: 100.00% (2,591/2,591 changed lines) - coverage gate passed ## Related Issues Follow-up to #4375 and alignment with `OPCF-Members/spec-drafts#31` and `OPCF-Members/spec-drafts#35`.

Align WoT conversion and runtime with Binding 1.1 (#4375)
## Summary Align the generic WoT/NodeSet converter, WoT Connectivity registry, and runtime binding implementation with the OPC UA WoT Binding 1.1 draft. ### Conversion and preservation - fix the standard placeholder ModellingRule NodeIds; - make every produced/restored NodeSet importable by completing required aliases; - support `ua:ComponentOf`, arbitrary companion ReferenceTypes, BrowseNames, InverseNames, symmetric references, and exact direction; - enforce the projection annotation allowlist and deterministic total order; - emit and consume Method argument schemas, EventType data, Alarms & Conditions, event severity, engineering units/ranges, localization, ValueRank, and ArrayDimensions; - preserve unsupported content through JSON residue/native projection rather than silently dropping it; - compare residue conflicts with RFC 8785 canonical equality while retaining byte-exact residue digests; - stamp generated documents with `uav:bindingVersion: "1.1"`. ### Runtime bindings - resolve an EventType Thing Model referenced with `tm:ref`, recursively derive its `data` fields as the baseline selection, and overlay explicit `uav:eventSelectClauses` that also reference EventType TMs; - pre-resolve EventType links asynchronously through the bounded sibling-document resolver before synchronous protocol planning; - retain read compatibility with legacy implementation-specific `uav:eventFields`; - expose nested event `data` matching the TD while retaining the flat transport field index for compatibility; - apply minimum-security constraints through deterministic endpoint selection and fail-closed session verification; - use one Unicode code-point comparer for projection membership and endpoint ties. ### Validation and fixtures - add strict, profile-aware validation while keeping default parsing permissive and residue-preserving; - pin 27 normative examples byte-for-byte to the specification repository, with an offline SHA-256 manifest and regeneration test; - regenerate checked-in WoT documents with the final canonical writer and binding version; - document the generic converter separately from the legacy OPC 10100-1 asset path. ## Notable compatibility changes - converted NodeSets may gain a completed `<Aliases>` table so standard ReferenceType names can be imported; - previously inverted/dangling placeholder ModellingRules are corrected; - generated documents gain binding-version, localization, rank/dimension, and exact ReferenceType metadata; - event data now has the nested shape described by the binding; - the former NodeId-based `uav:typeDefinitionId` clause is removed; event selections now use EventType-TM `tm:ref` links; - `uav:eventFields` remains readable but new documents use `uav:eventSelectClauses`; - unknown well-formed future revision/profile claims produce unsupported warnings rather than strict rejection. ## Generated files Most of the 621-file diff is deterministic regeneration: 517 checked-in WoT documents gain the binding version and final canonical spelling. Regeneration was run twice and is byte-idempotent. ## Validation - `dotnet restore UA.slnx`; - `dotnet build UA.slnx -c Release` across all configured TFMs; - `Opc.Ua.Types.Tests`: 9,215 net10.0; 9,208 net48; 9,208 net472; - `Opc.Ua.WotCon.Bindings.Tests`: 611 each on net10.0, net9.0, and net8.0; - `Opc.Ua.WotCon.Tests`: 1,136 net10.0; - `Opc.Ua.WotCon.Samples.Tests`: 14 net10.0; - NativeAOT test executable: 136/136; - all 27 strict fixture conversion/import checks; - formatting, analyzers, `git diff --check`, and regeneration idempotence. The full net48 run retains one unrelated existing MAX_PATH failure in `FileWotRegistryStoreTests.MultiLevelDirectoryCreationSyncsEveryModifiedParentInOrder`. Solution-wide stress runs also include an intentional 60-minute soak and unrelated locale-sensitive/flaky tests; all affected WoT projects and tests pass. ## Specification Depends on OPCF-Members/spec-drafts#31. --------- Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> Copilot-Session: 6a9f41b1-72f0-4c74-bd7f-26fa531e5738 |

Bound reconnect cleanup and organize samples by domain (#4276)
# Description This PR fixes bounded ManagedSession reconnect cleanup and reorganizes the sample applications into domain-focused folders. ## Reconnect cleanup - Bounds reconnect integration cleanup with independent 30-second close and dispose limits. - Sends `CloseSession` through the awaited transport request path during `Session.DisposeAsync`. - Preserves explicit `Session.CloseAsync` behavior that waits for or cancels outstanding publish requests. - Covers the disposal request path with a regression test. ## Sample organization - `samples/OpenUsd`: `GeneratorServer`, `SiteCompositionServer` - `samples/Redundancy`: `RedundantClient`, `RedundantServer`, `RedundantPubSub` - `samples/Isa95`: `MinimalIsa95Server` - `samples/MinimalApi`: `MinimalBoilerServer`, `MinimalCalcServer`, `MinimalClient` - `samples/DI`: `PumpDeviceIntegrationServer` - `samples/Lds`: `ConsoleLdsServer` - `samples/Reference`: `ConsoleReferenceClient`, `ConsoleReferenceServer` - `samples/PubSub`: `ConsoleReferencePubSubClient` `UA.slnx` now exposes the same requested domain groups. Project references, tests, runtime sample probes, CI workflows, Dockerfiles, Compose files, helper scripts, and documentation were updated to the new paths. `samples/Robotics/MinimalRobotServer` remains under `Robotics`. ## Validation - `dotnet build UA.slnx` - 3 Redundancy short-haul sample tests - 70 DI sample tests - 914 OpenUSD tests - 1 WotCon model-materialization test - 137 AOT tests - `docker compose config` for all 6 moved Redundancy Compose files ## Related Issues - Fixes #4273 ## 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. - [x] I built the complete `UA.slnx` solution locally. - [ ] I ran all tests locally against at least .NET Framework and .NET 10. - [ ] 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-swe-agent[bot] <198982749+Copilot@users.noreply.github.com> Co-authored-by: marcschier <11168470+marcschier@users.noreply.github.com> Co-authored-by: Marc Schier <mschier@microsoft.com> Co-authored-by: Marc Schier <marcschier@users.noreply.github.com> Copilot-Session: a2c2838f-74ae-4997-a1d4-50574d9e0636 |

Align the WoT implementation with spec: type binding, removed vocabulary, Alarms and Conditions (#4225)
# Description Aligns the WoT implementation with the normative changes in the OPC UA WoT specification drafts that the stack had not picked up, and fixes the defects that alignment surfaced. The driving artifact is [OPCF-Members/spec-drafts#19](https://github.com/OPCF-Members/spec-drafts/pull/19), *"bind a projected node to an already-loaded type, by name or by NodeId"*, which landed on the spec `main` after this repository last tracked it. ## 1. Bind a projected node to an existing type (Binding §5.2.1) §5.2.1 lets a document state that the node it projects is an instance of a type that **already exists** — one a companion model defines and the Server has loaded, or one a sibling document of the same conversion defines — so a converter binds to that type instead of defining a second type of the same shape. The converter hardcoded `HasTypeDefinition` to `BaseObjectType`, so a document that named its type projected an **untyped** node: a client browsing for the companion type would not find it, and nothing said why. Both forms are now implemented, resolved against the §5.1.5 **local context** — the other documents being converted together first, a loaded AddressSpace as the fallback. `IWotNodeResolver` supplies that context (is a namespace held; what does a qualified BrowseName match; what does an ExpandedNodeId identify), `WotCompositeNodeResolver` composes implementations in the specified order, and `NullWotNodeResolver` is the default that holds nothing. The converter needed no new async surface: the binding is resolved in a pre-resolve pass, exactly as Thing references already are, and the synchronous core consumes the result. The §5.2.1 table is honoured: a unique name binds; the link settles an ambiguous name; a name that resolves to nothing while the link resolves is **invalid** (that is a mistake in the name, not a shorthand for the identifier); two forms resolving to different Nodes are invalid; a resolved type of the wrong NodeClass is invalid. A binding naming a type the local context does not hold **fails** rather than falling back to `BaseObjectType` — a silently mistyped node is worse than a reported failure. A compact name is told from ordinary `@type` annotation **by namespace**, not by whether the lookup succeeds, so `saref:TemperatureSensor` on a Server that has never heard of SAREF stays the annotation it always was. The definitive form — a `ua:HasTypeDefinition` link whose `href` is the ExpandedNodeId of the type. An ExpandedNodeId matches exactly one Node or none, so it needs no lookup. A Node has exactly one `HasTypeDefinition`, so: - two such links → `AmbiguousTypeBinding` (6019), and the root keeps the default rather than being bound to a guess; - a link with no usable identifier → `InvalidTypeBinding` (6020); - no binding at all → the `BaseObjectType` default is unchanged. ## 2. Drop the six vocabulary terms `#19` removed `#19` deleted `uav:capability`, `uav:componentModel`, `uav:reference`, `uav:congruentType`, `uav:congruentTypeName` and `uav:nameNamespace` from the context, the JSON Schema and the ontology. A link now names its ReferenceType directly in `rel`, so the three link relations become `ua:HasInterface`, `ua:HasComponent` and `ua:NonHierarchicalReferences`, and the congruent-type pair is superseded by the §5.2.1 type binding. Their validation and mapping are removed; they are now ordinary residue like any other unrecognised term. ### A real gap this uncovered The converter knew **eight** ReferenceTypes by name and had neither `NonHierarchicalReferences` (`i=32`) nor `HasInterface` (`i=17603`) — so the two relations that *replace* `uav:reference` and `uav:capability` could not resolve at all. That includes example 02, which this repository vendors as a golden asset and which `#19` rewrote to use them. Both are now in the map. `uav:congruentType` was also the only term that redirected one reference to another while resolving a link target, so `ResolveTargetNodeIdAsync` no longer needs a loop. It resolves once and reports an unresolved target; the resolution context is still entered and the bytes still counted, so the per-conversion document, depth and byte bounds are unchanged. ## 3. Reject an out-of-range event severity instead of clamping it `uav:severity` had grown in this implementation without being a specification term. Rather than drop it, it is proposed upstream in [OPCF-Members/spec-drafts#21](https://github.com/OPCF-Members/spec-drafts/pull/21), which defines it with an explicit rule: the value **shall** be in the OPC 10000-5 range 1..1000, and a consumer **shall not** silently clamp it. The implementation clamped, so a document asking for severity 5000 was accepted and published as 1000 — the mistake was hidden while what the author asked for was changed. An affordance carrying an out-of-range severity is now skipped, with the reason logged, and its half-built event type and `GeneratesEvent` reference are removed. ### Defect found while making that change The occurrence-time path read `ValidateSeverity(severity) ?? tag.Severity`. Because `ValidateSeverity(null)` returns the 500 default, it **never** fell back to the affordance's authored severity: an occurrence reported without a severity published 500 rather than the authored 900. Build-time validation and the occurrence-time choice are now separate methods. ## 4. Vendored examples and honest coverage claims Examples 21 and 22 were missing from the vendored golden assets. Converting example 22 is now the end-to-end check for §5.2.1 — the specification's own example rather than a fixture written to match the implementation. `docs/WotBindings.md` claimed ten of the eleven conformance units and silently omitted **WoT-ConditionMapping**, and said "twenty worked examples". The count is corrected, and WoT-ConditionMapping is now **covered** — see §5 below. ## 5. Alarms and Conditions (Binding §13) The last unclaimed conformance unit. A projected Condition event now derives from the ConditionType it names rather than from `BaseEventType`; falling back would lose the Condition state model entirely, leaving a Client unable to tell an alarm from an ordinary event. The two forms follow the hint-plus-pin pattern of §5.3: `uav:conditionTypeId` is definitive and wins, `uav:conditionType` is a readable hint resolved for the four ConditionTypes §13.1 scopes. An unpinned name outside that set is reported rather than guessed. Four conformance rules are enforced, each because breaking it yields a document a consumer can read but cannot act on: | Rule | Section | Diagnostic | | --- | --- | --- | | A Condition event declares `EventId` in its `data` | 13.3 | `ConditionEventIdMissing` | | `uav:conditionAction` is inside its closed set | 13.2 | `InvalidConditionAction` | | `uav:actsOn` names a Condition event in the same document | 13.4 | `InvalidConditionTarget` | | `Acknowledge`/`Confirm`/`AddComment` declare an `EventId` input | 13.4 | `ConditionActionInputMissing` | `Enable` and `Disable` act on the Condition instance rather than one occurrence and are deliberately exempt from the last rule, pinned by a negative test. Shelving, suppression, dialog conditions and `ConditionRefresh` stay out of scope, as §13.1 scopes the mapping. ## 6. The sibling half of the §5.1.5 local context `SnapshotWotNodeResolver` indexes the registry snapshot a conversion runs over and is wired into `WotNodeSetDocumentConverter`, so a document naming a type another document in the same registry projects resolves with no AddressSpace at all. Only Thing Models are indexed: a Thing Model projects a `UAObjectType` and is a valid target, a Thing Description projects an instance and never is. Identity comes from the new public `WotNodeSetConverter.TryDescribeProjectedType`, which applies exactly the rules the conversion uses, so an index entry and the projected node cannot drift apart. Ambiguity is preserved rather than resolved: two siblings sharing a qualified name yield both matches so the caller can report it. ## Deliberately not in this PR - **The AddressSpace-backed `IWotNodeResolver`.** The abstraction, the composite, the null default and the sibling-document implementation ship here; the AddressSpace-backed half needs a cached type-hierarchy walk behind a server `OperationContext` and follows separately. Until it exists a host gets the sibling context plus the null fallback, which reports a binding as unresolved rather than mistyping it. - **Two §5.2.1 obligations that need the address space**: not duplicating a mandatory instance declaration of the resolved type, and rejecting disagreement with an instantiated Thing Model. - **Connectivity §7.3 parent resolution.** Each is tracked; none is faked here. ## Related Issues There is no tracking issue: this came out of a spec-versus-implementation audit rather than a reported defect, and the driving artifacts are the two upstream spec PRs linked above. Happy to open one if maintainers prefer — the §5.2.1 follow-up in particular is worth an ADR, since the local-context resolver is a new injectable provider spanning two assemblies. ## 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. ### Verification detail | | net10.0 | net48 | |---|---|---| | `Opc.Ua.Types.Tests` | 8573 / 8573 | 8555 / 8555 | | `Opc.Ua.WotCon.Tests` | 1075 / 1075 | 1075 / 1075 | Full `UA.slnx` build: **0 errors, 0 warnings** across all target frameworks, re-verified after `master` was merged into the branch. Every new test was mutation-verified: the type-binding tests against three mutations (revert to the hardcoded default, drop the ambiguity check, accept an empty `href`), the severity tests against reinstating the clamp, and the ReferenceType additions against removing them from the map. Each mutation failed the suite before the change was kept. --------- Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> Copilot-Session: 9e6a5abf-3299-4cd1-9855-010fedbf0ad8 |

[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 |
