Verification status

JavaScript suite

The repository currently contains 77 contract and unit tests. They cover:

• Reconciler creation, movement, removal, and commit batching
• Prop validation and all-or-nothing serialization
• Host handshake, process exit, and request timeouts
• Controlled-value sequence acknowledgements and enforcement
• Menu, toolbar, presentation, selection, and sorting semantics
• Screenshot success, failure, and timeout behavior

Linux CI runs the JavaScript tests, package build, and typecheck.

macOS

The macOS CI job compiles the Swift host and runs the JavaScript suite and package build. GUI verification is local because hosted CI has no normal window session.

Local real-window suites cover:

• Base demo in Node mode
• Kitchen-sink app-shell and multi-component workflows
• Embedded JavaScriptCore demo

They assert native tree dumps, interaction events, optimistic edits, sequence acknowledgements, and host-rendered PNG files.

Windows

The blocking Windows CI job compiles the Release x64 WinUI host with .NET 8.

The base Node-mode suite has also passed locally against a real WinUI 3 window, including screenshots and controlled-input stress behavior.

The newer app-shell kinds are currently compile-checked on Windows. They have not yet received the same real-window end-to-end suite as macOS.

Evidence limits

• Tree dumps prove host node state, not every visual detail.
• PNG validation proves captured window content, not popup layers outside the captured surface.
• Debug events prove protocol handling, not physical pointer or keyboard routing.
• Current checks do not constitute a complete accessibility audit.
• The real-window suites do not visit every public component. The component catalog is validated separately against all 37 public exports.
