From 0cc0236384f2640cedc6ea44e707a9c8108f0cf6 Mon Sep 17 00:00:00 2001 From: Malcolm Nixon Date: Mon, 20 Jul 2026 14:38:31 -0400 Subject: [PATCH 1/2] Add read-only source text viewer with SysML v2 syntax highlighting - Double-clicking a .sysml file in the Workspace panel opens a new read-only tab showing the file's raw text, syntax highlighted via AvaloniaEdit (new Avalonia.AvaloniaEdit 12.0.0 dependency). - MainWindowShell: new WorkbenchTabKind.SourceText, WorkbenchTab.FilePath, OpenSourceTextTab (dedupes/refocuses an already-open tab for the same file) and GetTabFilePath. - New SourceTextDocumentViewModel/SourceTextDocumentView; self-authored Assets/SysML.xshd highlighting definition (keywords reflected from SysMLv2Lexer with a static fallback), plus comment/string/number rules. - WorkbenchDockFactory: additive SourceTextTabClosed event; existing DiagramTabClosed/Dock OTS artifacts left untouched. - MainWindowView: tab-tracking widened to the common Document base type to host both diagram and source-text tabs in the same tabbed area. - WorkspacePanelToolView: double-tap handling to open .sysml files. - Tests: MainWindowShellTests extended; new SourceTextDocumentViewModelTests and OtsSoftwareTests/AvaloniaEditTests. - Companion docs: design/verification/reqstream/sysml2-model updates for MainWindowShell and WorkspacePanel, new AvaloniaEdit OTS design/ verification/reqstream docs registered in requirements.yaml, ots.sysml, and .reviewmark.yaml (including the new AvaloniaEditTests.cs review coverage);

The tab's Text property was still set correctly, so the existing view-model-level tests never caught it - only the actual visual tree was empty. Added a headless regression test that hosts a real TextEditor in a real shown Window and asserts it gets a template/visual children, which fails without the style include and passes with it.
