…fecycle events, validation errors Surface lifecycle: OnSurfaceCreated/OnSurfaceDeleted events on SurfaceManager with EventCallback parameters on A2UISurface for declarative binding. Local actions: LocalActionRegistry service for client-side functionCall execution without server round-trip, registered via AddA2UIBlazor(configureLocalActions:). Optimistic updates: Input components update the local data model immediately on user interaction via ApplyOptimisticUpdate(), before the server responds. SurfaceManager changed from [CascadingParameter] to [Inject] on A2UIComponentBase. Validation errors: Server error messages stored per data-model path on A2UISurfaceState; input components render inline validation with component-error-takes-precedence semantics. Also adds NuGet package icon and design doc for traceability. 273 unit tests, 46 E2E tests, 0 warnings. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
ServerFixture: Use port 5050 for the test Python server (matching the default appsettings.json) because .NET 10 Blazor WASM does not load environment-specific appsettings files at runtime. The previous appsettings.Testing.json approach silently broke when migrating to .NET 10 — the WASM client always connected to port 5050 regardless. Added KillListenerOnPort() using lsof -sTCP:LISTEN to safely clear the port before binding. Also drain stdout/stderr with BeginOutputReadLine() to prevent child process deadlock from pipe buffer filling. CLAUDE.md: Updated kill port guidance to use -sTCP:LISTEN flag, which targets only the listening process and avoids killing remote sessions. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
CHANGELOG: Full release history from v0.1.0 through v0.5.0. README: Fix .NET 8 → .NET 10, update test counts (273 unit, 46 E2E), add project status summary, link to Changelog and Specification. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
