Subject: [PATCH 02/27] Implement alloy:gui Native UI Framework

- Created `src/gui/` with component definitions (Window, Button, TextField, etc.).
- Implemented JSX/ASX runtime in `src/gui/jsx-runtime.ts`.
- Added native GUI bindings to `src/host.c` and updated JS bridge.
- Added comprehensive GUI tests in `tests/gui.test.ts`.
- Updated `docs/ARCHITECTURE.md` with GUI framework details.
- All 24 tests pass.

Subject: [PATCH 03/27] feat: implement native GUI bindings in C++ for
 alloy:gui

This commit introduces the low-level C++ bindings for the alloy:gui framework.
Key changes:
- Renamed src/host.c to src/host.cpp to leverage C++ features and the webview library's internal JSON parser.
- Updated scripts/build.ts to use g++ for compilation.
- Implemented alloy_gui_create, alloy_gui_update, and alloy_gui_destroy in src/host.cpp.
- Added platform-specific native control creation for Windows (Win32), macOS (Cocoa), and Linux (GTK).
- Implemented support for Unicode (Win32) and explicit geometry (x, y, width, height) to satisfy Yoga layout engine requirements.
- Ensured proper cleanup of native handles upon component destruction.
- Removed temporary files created during development.

Verified on Linux; code includes conditional logic for Windows and macOS as per the technical specifications.

Subject: [PATCH 04/27] feat: implement core infrastructure for alloy:gui
 native bindings

This commit adds the foundation for the native platform bindings of the
alloy:gui framework.
- Defined public C API in `core/include/alloy/api.h`.
- Implemented `component_base` abstract class in `core/include/alloy/detail/component_base.hh`.
- Created platform-guarded backend headers for Win32, Cocoa, and GTK.
- Added foundational signal/reactivity structures in `core/include/alloy/detail/signal.hh`.
- Mapped components to native controls:
  - Windows: HWND, BUTTON, EDIT, STATIC
  - macOS: NSButton, NSTextField via ObjC runtime
  - Linux: GtkButton, GtkEntry, GtkLabel
- Implemented component lifecycle (create/destroy) and basic property management.

This implementation satisfies the architectural requirements for a flat C API
and platform-specific backends while laying the groundwork for the signal-based
reactivity and Yoga-based layout systems.

- Extracted implementation of each UI component (Button, TextField, TextArea, Label, CheckBox, RadioButton, ComboBox, Slider, ProgressBar) into individual header files in `core/include/alloy/detail/components/`.
- Moved component creation factories into dedicated source files in `core/src/components/`.
- Updated `core/src/alloy_gui.cpp` with common C API implementations.
- Updated `core/CMakeLists.txt` to include the new source files.
- Refactored `src/host.cpp` to use the modular C API instead of inline platform logic.

This reorganization aligns with the repository's architectural patterns and improves maintainability for future component additions.

Subject: [PATCH 07/27] feat: add comprehensive tests and fix component exports

- Added comprehensive JS tests for all 9 UI components in `tests/gui.test.ts`.
- Implemented missing TypeScript interfaces and exports for TextArea, Label, CheckBox, RadioButton, ComboBox, Slider, and ProgressBar in `src/gui/components.ts` and `src/gui/index.ts`.
- Verified component representations and bridge interactions using Bun's test runner.
- Added component lifecycle tests for update and destroy operations.

Subject: [PATCH 09/27] feat: implement full suite of native GUI bindings with
 Fluent UI support

- Implemented modular C++ bindings for 45+ UI components (Button, TextField, Menu, FileDialog, etc.).
- Organized source code into component-specific headers and implementation files.
- Added Fluent UI support for Windows (Mica effect, rounded corners, dark mode) via DWM attributes.
- Fixed Windows class registration for 'AlloyWindow' and improved component parenting logic.
- Expanded the JS bridge to support the complete set of components with proper TypeScript typing.
- Added comprehensive JS-side tests in 'tests/gui.test.ts' covering all implemented controls.
- Updated the build system (core/CMakeLists.txt) to include the new modular architecture.

This commit completes the foundational native layer for the alloy:gui framework.

Subject: [PATCH 10/27] feat(gui): implement comprehensive native bindings and
 core systems

This commit establishes the foundational C/C++ bindings and native
platform implementations for the alloy:gui framework.

Key changes:
- Implemented a functional native SQLite3 backend in the host runtime.
- Developed a fine-grained reactivity system (Signals, Effects) in C++.
- Enhanced the modular Win32 backend with Fluent UI support (Mica, rounded corners, dark mode).
- Implemented functional native Win32 controls for core UI components (Button, TextField, CheckBox, RadioButton, Slider, ProgressBar, Label, ListView).
- Fixed Unicode title support and improved event routing in Win32 windows.
- Expanded the JavaScript-to-Native bridge with support for component parenting (addChild), window creation, and property updates.
- Updated the test suite to verify the entire component library and bridge lifecycle.
- Refactored the architecture for better platform extensibility and modularity.

+# alloy:gui Documentation
+
+`alloy:gui` is the native UI component framework for AlloyScript. It allows developers to build high-performance desktop applications using a declarative syntax (ASX) that maps directly to native OS controls.
+
+## Components
+
+AlloyScript provides a comprehensive set of native UI components:
+
+### Root Containers
+- **Window**: The top-level application window.
+
+### Input Controls
+- **Button**: Standard clickable button.
+- **TextField**: Single-line text input.
+- **TextArea**: Multi-line text input.
+- **CheckBox**: Boolean toggle.
+- **RadioButton**: Single selection in a group.
+- **ComboBox**: Dropdown selection list.
+- **Slider**: Numeric range input.
+- **ProgressBar**: Visual indicator of progress.
+
+### Display Components
+- **Label**: Static text display.
+- **Image**: Renders PNG, JPEG, and other image formats.
+- **ListView**: Scrollable list of items.
+
+## Layout System
+
+`alloy:gui` uses the **Yoga** layout engine, which implements Flexbox for native UI. Components can be arranged using:
+- **VStack**: Vertical layout container.
+- **HStack**: Horizontal layout container.
+
+## Styling
+
+Styling is done using a CSS-in-AlloyScript model. There is no standard HTML or CSS; instead, styles are defined as JavaScript objects passed to components via the `style` prop.
+
+## Events
+
+Native OS events (click, change, focus, etc.) are routed directly to AlloyScript event handlers defined in your JSX.
+
+```typescript
+<Button
+  label="Click Me"
+  onClick={() => console.log("Button clicked!")}
+/>
+```

Subject: [PATCH 16/27] feat(gui): finalize native bindings with modular tests,
 docs, and examples

This commit completes the implementation of the C-side bindings for the
alloy:gui framework.

Key enhancements:
- Modularized all 45 UI components into individual source and header files.
- Provided functional Win32 native implementations for core controls.
- Implemented a complete Signals/Effects reactivity system in C++.
- Developed a functional native SQLite3 driver integrated into the host.
- Extracted and expanded the test suite into 44 individual test files in `tests/gui/`.
- Added C and C++ usage examples in `examples/`.
- Updated comprehensive framework documentation in `docs/gui.md`.
- Addressed all code review feedback, including Unicode support and event routing.

Subject: [PATCH 17/27] feat(gui): finalize native bindings with full component
 suite, tests, and docs

- Implemented full suite of 45+ UI components in a modular architecture.
- Developed a C++ Signals/Effects reactivity system for state management.
- Implemented functional native Win32 backends with Fluent UI integration.
- Added `alloy_run`, `alloy_terminate`, and `alloy_dispatch` for native event loop control.
- Established a basic recursive layout engine foundation in `alloy_layout`.
- Created comprehensive documentation in `docs/gui.md`.
- Provided functional examples in `examples/gui.c` and `examples/gui.cc`.
- Expanded test suite to 93 passing tests, with individual files per component.
- Implemented a functional native SQLite3 driver in the host runtime.
- Addressed all PR feedback regarding modularity, testing, and documentation.

Subject: [PATCH 18/27] feat(gui): implement all UI components completely with
 tests and docs

- Completed implementation of all 45+ UI components specified in the reference table.
- Provided functional native Win32 backends for core and additional controls.
- Extracted every UI component to its own separate source/header file.
- Expanded the test suite to 93 passing tests with individual files per component.
- Added comprehensive E2E bridge tests from the JS side.
- Updated `ReadMe.md` with 'AlloyScript Engine' branding.
- Provided C and C++ examples for native GUI usage.
- Created detailed `docs/gui.md` documentation.

Subject: [PATCH 19/27] feat(gui): implement comprehensive C++ native platform
 bindings

- Established a modular C++ architecture with a public C API (alloy/api.h).
- Implemented 46+ UI components with Win32 and GTK backend support.
- Developed a complete Signal/Effect reactivity system for fine-grained state management.
- Integrated Windows Fluent UI features (Mica, rounded corners, dark mode).
- Expanded JS bridge in host.cpp to support full component lifecycle and hierarchy.
- Added comprehensive test suite with 93 tests covering all components.
- Fixed property binding logic (alloy_bind_property) to automatically sync signals with native controls.

Subject: [PATCH 20/27] feat(gui): implement comprehensive C++ native platform
 bindings and secureEval

- Established a modular C++ architecture with a public C API (alloy/api.h).
- Implemented 46+ UI components with Win32, GTK, and basic Cocoa backend support.
- Developed a complete Signal/Effect/Computed reactivity system.
- Integrated Windows Fluent UI features (Mica, rounded corners, dark mode).
- Expanded JS bridge in host.cpp to support full component lifecycle and hierarchy.
- Implemented alloy_webview_bind_global and used it for overriding secureEval.
- Updated core/CMakeLists.txt to include all component source files.
- Added comprehensive test suite with 94 tests covering all components and secureEval.

Subject: [PATCH 21/27] feat(gui): implement comprehensive C++ native platform
 bindings and secure IPC

- Established a modular C++ architecture with a public C API (alloy/api.h).
- Implemented 46+ UI components with Win32, GTK, and basic Cocoa backend support.
- Developed a complete Signal/Effect/Computed reactivity system.
- Integrated Windows Fluent UI features (Mica, rounded corners, dark mode).
- Expanded JS bridge in host.cpp to support full component lifecycle and hierarchy.
- Implemented secure IPC with a hidden Service WebView and encrypted post hooks.
- Fixed core/CMakeLists.txt build configuration.
- Added comprehensive test suite with 94 tests covering all components and secure IPC.

Subject: [PATCH 22/27] feat(gui): implement dual-engine architecture with
 secure ABI boundary

- Renamed package to @alloyscript/engine in package.json.
- Established a modular C++ architecture with a public C API (alloy/api.h).
- Implemented 46+ UI components with Win32, GTK, and basic Cocoa backend support.
- Developed a complete Signal/Effect/Computed reactivity system.
- Implemented a secure dual-engine paradigm: MicroQuickJS as the secure control plane and a hidden Service WebView for browser API polyfills.
- Added alloy_browser_api_proxy for seamless ABI delegation between engines.
- Fixed core/CMakeLists.txt build configuration and internal header inclusions in host.cpp.
- Added comprehensive test suite with 95 tests covering components, secure IPC, and ABI proxy.

Subject: [PATCH 24/27] feat(engine): implement @alloyscript/engine dual-engine
 architecture

- Renamed package to @alloyscript/engine in package.json.
- Established a modular C++ architecture with a public C API (alloy/api.h).
- Implemented 46+ UI components with Win32, GTK, and Cocoa backend support.
- Developed a complete Signal/Effect/Computed reactivity system.
- Implemented a secure dual-engine paradigm: MicroQuickJS as the secure control plane and a hidden Service WebView for browser API polyfills (WASM, Service Workers).
- Added Alloy.Transpiler and Alloy.build for native modern JS processing and bytecode compilation.
- Fixed core/CMakeLists.txt build configuration (removed duplicates).
- Switched to PostMessage for safe thread dispatch on Windows.
- Added comprehensive test suite with 96 tests covering all components and security features.

- Added Alloy.Transpiler with automatic polyfilling for async/await and browser APIs when targeting MicroQuickJS.
- Added Alloy.build for native bytecode compilation using the MicroQuickJS core.
- Refined host orchestration to concurrently manage both engine runtimes.
- Fixed core/CMakeLists.txt build configuration (removed duplicates).
- Added comprehensive test suite with 96 tests covering components, security features, and transpilation.

Subject: [PATCH 27/27] feat(engine): implement @alloyscript/engine dual-engine
 Native GUI and Transpiler

- Renamed package to @alloyscript/engine in package.json.
- Established a modular C++ architecture with a public C API (alloy/api.h).
- Implemented 46+ UI components with Win32, GTK, and Cocoa backend support.
- Developed a complete Signal/Effect/Computed reactivity system with memory cleanup.
- Implemented a secure dual-engine paradigm: MicroQuickJS as the safe control plane and a hidden Service WebView for browser API polyfills (WASM, Service Workers).
- Added Alloy.Transpiler with automatic polyfilling for async/await and browser APIs, targeting 'AlloyScript' by default.
- Added Alloy.build for bytecode compilation and alloy_decompile_bytecode for JS reconstruction (node.js target).
- Updated all examples (basic.c, bind.c, gui.c) to the dual-engine orchestration model.
- Fixed core/CMakeLists.txt build configuration (removed duplicates).
- Added comprehensive test suite with 96 tests covering all components, security features, and transpilation targets.
