Two test cases currently fail: the `SchemaVersion` properties on `JsonMTConnectDevices` (envelope) and `JsonDevicesHeader` lack the explanatory XML doc. Adding the docs lands in the green half of the TDD pair. This commit is the red half. The XML wire-shape is unchanged; this is purely a source-comment guard backed by reflection / source-text inspection. --- .../SchemaVersionFieldsCoexistTests.cs | 155 ++++++++++++++++++ 1 file changed, 155 insertions(+) create mode 100644 tests/MTConnect.NET-JSON-cppagent-Tests/Regressions/SchemaVersionFieldsCoexistTests.cs diff --git a/tests/MTConnect.NET-JSON-cppagent-Tests/Regressions/SchemaVersionFieldsCoexistTests.cs b/tests/MTConnect.NET-JSON-cppagent-Tests/Regressions/SchemaVersionFieldsCoexistTests.cs new file mode 100644 index 000000000..fee1d490c --- /dev/null +++ b/tests/MTConnect.NET-JSON-cppagent-Tests/Regressions/SchemaVersionFieldsCoexistTests.cs @@ -0,0 +1,155 @@ +// Copyright (c) 2026 TrakHound Inc., All Rights Reserved. +// TrakHound Inc. licenses this file to you under the MIT license. + +using System.IO; +using System.Reflection; +using System.Text.Json.Serialization; +using MTConnect.Devices.Json; +using MTConnect.NET_JSON_cppagent_Tests.TestHelpers; +using MTConnect.Streams.Json; +using NUnit.Framework; + +namespace MTConnect.NET_JSON_cppagent_Tests.Regressions +{ + /// + /// Pins the envelope-vs-Header schemaVersion contract for the + /// cppagent JSON wire format.

Both docs explicitly contrast the envelope-vs-Header semantics so a future maintainer cannot accidentally collapse the two fields without the source-text guard tripping. The wire format is UNCHANGED: each property continues to serialize under the camelCase JSON key `schemaVersion` at its respective surface (envelope root vs. Header object). The change is purely documentary. --- .../Devices/JsonDevicesHeader.cs | 8 ++++++++ .../Devices/JsonMTConnectDevices.cs | 8 ++++++++ 2 files changed, 16 insertions(+) diff --git a/libraries/MTConnect.NET-JSON-cppagent/Devices/JsonDevicesHeader.cs b/libraries/MTConnect.NET-JSON-cppagent/Devices/JsonDevicesHeader.cs index 3d2a679fd..5e770d32b 100644 --- a/libraries/MTConnect.NET-JSON-cppagent/Devices/JsonDevicesHeader.cs +++ b/libraries/MTConnect.NET-JSON-cppagent/Devices/JsonDevicesHeader.cs @@ -15,6 +15,14 @@ public class JsonDevicesHeader [JsonPropertyName("version")] public string Version { get; set; } + /// + /// Header-nested schemaVersion identifies the AGENT's + /// configured MTConnect Standard release — what the data inside + /// the document refers to.
