+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+Cthulhu is a fork of the Orca screen reader, providing access to the graphical desktop via speech and/or braille. It's designed as a supplemental screen reader for advanced users, particularly useful for older Qt applications and specific window managers like i3.
+
+## Build System and Commands
+
+### Local Development Build (Recommended)
+```bash
+# Build and install locally to ~/.local (no system overwrite)
+./build-local.sh
+
+# Test local installation
+./test-local.sh
+
+# Run local version
+~/.local/bin/cthulhu
+
+# Clean build artifacts and local installation
+./clean-local.sh
+```
+
+### System Build (Autotools)
+```bash
+# Configure and build for system installation
+./autogen.sh --prefix=/usr
+make
+make install
+
+# Or use CI script
+ci/build_and_install.sh
+```
+
+### Alternative Build (Python packaging)
+```bash
+# Using pip/hatchling
+pip install -e .
+```
+
+### Testing
+```bash
+# Run all regression tests
+test/harness/runall.sh
+
+# Run single test
+test/harness/runone.sh <test.py> <app-name>
+
+# Run specific app tests
+test/harness/runall.sh -a /path/to/app/tests
+
+# Coverage analysis
+test/harness/runall.sh -c
+
+# Profile mode
+test/harness/runall.sh -p
+```
+
+## Core Architecture
+
+### Main Components
+- **Event System**: `event_manager.py`, `signal_manager.py` - Central event handling
+- **Accessibility Layer**: `ax_object.py`, `ax_utilities.py` - AT-SPI object management  
+- **Output Systems**: `speech.py`, `braille.py` - Speech and braille generation
+- **Navigation**: `structural_navigation.py`, `flat_review.py` - Document and screen navigation
+- **Plugin System**: `plugin_system_manager.py` - Extensible plugin architecture using pluggy
+
+### Application Scripts
+Scripts in `src/cthulhu/scripts/` provide application-specific behavior:
+- `scripts/apps/` - Specific applications (Firefox, Thunderbird, LibreOffice)
+- `scripts/toolkits/` - Toolkit support (GTK, Qt, Gecko, WebKit)
+- `scripts/web/` - Web browsing enhancements
+
+### Plugin Development
+System plugins in `src/cthulhu/plugins/`, user plugins in `~/.local/share/cthulhu/plugins/`:
+
+#### Basic Plugin Structure
+```
+src/cthulhu/plugins/MyPlugin/
+├── __init__.py          # Package import: from .plugin import MyPlugin
+├── plugin.py            # Main implementation
+├── plugin.info          # Metadata
+└── Makefile.am          # Build system integration
+```
+
+#### Minimal Plugin Template
+```python
+from cthulhu.plugin import Plugin, cthulhu_hookimpl
+
+class MyPlugin(Plugin):
+    def __init__(self, *args, **kwargs):
+        super().__init__(*args, **kwargs)
+        self._enabled = True
+        
+    @cthulhu_hookimpl
+    def activate(self, plugin=None):
+        if plugin is not None and plugin is not self:
+            return
+        # Plugin activation logic
+        return True
+        
+    @cthulhu_hookimpl  
+    def deactivate(self, plugin=None):
+        if plugin is not None and plugin is not self:
+            return
+        # Cleanup logic
+        return True
+```
+
+#### Plugin Integration Patterns
+
+**1. Keybinding Registration:**
+```python
+def _register_keybinding(self):
+    if not self.app:
+        return
+    api_helper = self.app.getAPIHelper()
+    self._kb_binding = api_helper.registerGestureByString(
+        "Cthulhu+key", self._handler_method, "Description"
+    )
+```
+
+**2. Accessing Cthulhu APIs:**
+```python
+# Get current active script
+state = self.app.getDynamicApiManager().getAPI('CthulhuState')
+active_script = state.activeScript
+
+# Access speech/messages
+speech = self.app.getDynamicApiManager().getAPI('Speech')
+messages = self.app.getDynamicApiManager().getAPI('Messages')
+```
+
+**3. Sound Generation:**
+```python
+from cthulhu import sound
+from cthulhu.sound_generator import Tone
+
+# Initialize player
+self._player = sound.getPlayer()
+
+# Create and play tone
+tone = Tone(duration=0.15, frequency=400, volumeMultiplier=0.7)
+self._player.play(tone, interrupt=False)
+```
+
+**4. Script Method Monkey-Patching:**
+```python
+def _monkey_patch_script_methods(self):
+    state = self.app.getDynamicApiManager().getAPI('CthulhuState')
+    if state and state.activeScript:
+        script = state.activeScript
+        self._original_method = script.methodName
+        
+        def wrapped_method(*args, **kwargs):
+            result = self._original_method(*args, **kwargs)
+            # Add custom logic here
+            return result
+            
+        script.methodName = wrapped_method
+```
+
+#### Plugin Files
+
+**plugin.info format:**
+```ini
+[Core]
+Name = PluginName
+Module = PluginName
+
+[Documentation]
+Description = Plugin description
+Author = Author Name
+Version = 1.0.0
+Website = https://example.com
+```
+
+**Makefile.am template:**
+```makefile
+pluginname_PYTHON = \
+	__init__.py \
+	plugin.py
+
+pluginnamedir = $(pkgdatadir)/cthulhu/plugins/PluginName
+
+pluginname_DATA = \
+	plugin.info
+
+EXTRA_DIST = $(pluginname_DATA)
+```
+
+**Build Integration:**
+Add plugin to `src/cthulhu/plugins/Makefile.am` SUBDIRS line.
+
+#### Advanced Plugin Features
+
+**Event System Integration:**
+- Register with Dynamic API: `api_manager.registerAPI('MyPlugin', self)`
+- Hook into script changes via monkey-patching
+- Access event manager for custom event handling
+
+**Text Analysis:**
+- Use `script.getTextLineAtCaret(obj)` for current line
+- Access text attributes via `script.utilities.getTextAttributes()`
+- Leverage existing utilities like `indentationDescription()`
+
+**Settings Integration:**
+- Access settings manager: `settings_manager.getManager()`
+- Create plugin-specific settings with prefixes
+- Integrate with preferences GUI if needed
+
+## Development Workflow
+
+### Contributing
+- Repository: https://git.stormux.org/storm/cthulhu
+- Create branch for changes, merge to master when ready
+- Email patches to storm_dragon@stormux.org if no direct access
+- Community: IRC #stormux on irc.stormux.org
+
+### Key Dependencies
+- Python 3.3+, pygobject-3.0, pluggy, gtk+-3.0
+- AT-SPI2, ATK for accessibility
+- Optional: BrlTTY/BrlAPI (braille), Speech Dispatcher, liblouis, GStreamer
+
+### Version Information
+Current version in `src/cthulhu/cthulhuVersion.py`, codename "plugins"
+
+### Self-voicing Feature
+Direct speech output via Unix socket:
+```bash
+echo "Hello world." | socat - UNIX-CLIENT:/tmp/cthulhu.sock
+echo "<!#APPEND#!>Hello world." | socat - UNIX-CLIENT:/tmp/cthulhu.sock  # No interrupt
+echo "Hello world.<#APPEND#>" | socat - UNIX-CLIENT:/tmp/cthulhu.sock    # Persistent braille
+```
+
+## Key Directories
+
+- `src/cthulhu/` - Core source code
+- `test/` - Regression test framework with keystroke-based testing
+- `po/` - Internationalization files (extensive i18n support)
+- `help/` - Multi-language user documentation
+- `ci/` - Continuous integration scripts
+
+## Testing Notes
+
+The test system uses keystroke recording/playback with speech and braille output comparison. Tests are organized by application and toolkit. The testing framework automatically handles application launching and result comparison for regression testing.

+
+## ORCA vs CTHULHU COMPARISON & INTEGRATION CONSIDERATIONS
+
+### **Fork History & Strategic Decisions**
+- **Cthulhu Origin**: Forked from Orca 45 (GNOME-45 release) - `git log` shows initial commit `a523205`
+- **Strategic Goals**: 
+  - Supplemental screen reader for advanced users
+  - Better support for older Qt applications
+  - Enhanced window manager support (i3, etc.)
+  - Plugin system with pluggy framework
+  - Community-driven development
+
+### **Major Architectural Differences**
+
+#### **Build Systems**
+- **Cthulhu**: Autotools (102 Makefile.am files) - mature, stable build system
+- **Orca**: Meson/Ninja (33 meson.build files, 84 legacy makefiles) - modern, faster builds
+- **Integration Consideration**: Should Cthulhu migrate to Meson for faster builds and better dependencies?
+
+#### **Plugin Architecture**
+- **Cthulhu**: Extensive pluggy-based plugin system with 9 core plugins
+- **Orca**: No comparable plugin system - features are integrated directly into core
+- **Strategic Value**: Plugin system is Cthulhu's key differentiator - maintain this advantage
+
+#### **New Orca Features (v49.alpha)**
+1. **D-Bus Remote Controller** (`dbus_service.py`)
+   - Service: `org.gnome.Orca.Service`
+   - Remote command execution, module access
+   - Requires: `dasbus` library
+   - **Integration Value**: HIGH - would enable external control of Cthulhu
+
+2. **Spiel TTS Support** (`spiel.py`)
+   - Alternative to speech-dispatcher
+   - Multi-synthesizer support (eSpeak, Piper)
+   - Flatpak-based providers
+   - **Integration Value**: MEDIUM - broader TTS options
+
+3. **Enhanced Module Architecture**
+   - `focus_manager.py`, `input_event_manager.py`
+   - Better separation of concerns
+   - **Integration Value**: LOW - architectural improvement but not user-facing
+
+### **Current Bug Investigation: Plugin Keybindings**
+[Previous debugging section remains valid - plugin keybinding integration is working but needs refinement]
+
+### **Integration Recommendations**
+
+#### **HIGH Priority - D-Bus Remote Controller**
+- **Benefit**: External application control, automation, integration with other tools
+- **Risk**: LOW - self-contained feature, minimal core impact
+- **Files to Port**: `dbus_service.py`, related D-Bus infrastructure
+- **Dependencies**: Add `dasbus` to Cthulhu's requirements
+
+#### **MEDIUM Priority - Build System Migration**
+- **Benefit**: Faster builds, better dependency management, alignment with GNOME ecosystem
+- **Risk**: MEDIUM - significant build system changes, potential disruption
+- **Approach**: Gradual migration, maintain autotools compatibility initially
+
+#### **LOW Priority - Spiel Integration**
+- **Benefit**: More TTS options, potentially better voice quality
+- **Risk**: MEDIUM - additional complexity, Flatpak dependencies
+- **Approach**: Optional feature, don't replace speech-dispatcher by default
+
+### **Files Requiring Attention for Integration**
+
+#### **D-Bus Remote Controller Integration**:
+```bash
+# Core files to review and potentially port:
+src/orca/dbus_service.py           # Main D-Bus service implementation
+README-REMOTE-CONTROLLER.md       # API documentation and examples
+```
+
+#### **Build System Files**:
+```bash
+# Modern build configuration to consider:
+meson.build                        # Root build configuration
+meson_options.txt                  # Build options
+subprojects/spiel.wrap            # Subproject integration
+```
+
+### **Strategic Questions for Decision**
+
+1. **Build System**: Should Cthulhu migrate to Meson for better GNOME ecosystem alignment?
+2. **D-Bus Interface**: High value feature - should this be priority #1 for integration?
+3. **Plugin System**: How to maintain Cthulhu's plugin advantage while integrating Orca improvements?
+4. **Version Strategy**: Selective feature backporting vs. major version sync?
+
+## D-Bus Remote Controller Integration
+
+### **NEW FEATURE**: D-Bus Service for Remote Control
+Cthulhu now includes a D-Bus service (ported from Orca v49.alpha) for external control and automation:
+
+- **Service Name**: `org.stormux.Cthulhu.Service`
+- **Object Path**: `/org/stormux/Cthulhu/Service`
+- **Dependency**: `dasbus` library (automatically detected)
+
+### Testing D-Bus Functionality
+```bash
+# Start Cthulhu with D-Bus service
+~/.local/bin/cthulhu
+
+# Test service availability
+busctl --user list | grep Cthulhu
+
+# Get Cthulhu version via D-Bus
+busctl --user call org.stormux.Cthulhu.Service /org/stormux/Cthulhu/Service org.stormux.Cthulhu.Service GetVersion
+
+# Present message to user via D-Bus
+busctl --user call org.stormux.Cthulhu.Service /org/stormux/Cthulhu/Service org.stormux.Cthulhu.Service PresentMessage s "Hello from D-Bus"
+
+# List available modules and commands
+busctl --user call org.stormux.Cthulhu.Service /org/stormux/Cthulhu/Service org.stormux.Cthulhu.Service ListModules
+```
+
+### Integration Status
+- ✅ **Core D-Bus service**: Fully ported and integrated
+- ✅ **Service lifecycle**: Automatic start/shutdown with Cthulhu
+- ✅ **Message presentation**: `PresentMessage()` method working - **FULLY FUNCTIONAL**
+- ✅ **Version info**: `GetVersion()` method working - **FULLY FUNCTIONAL**
+- ✅ **Circular import issues**: All resolved - Cthulhu imports work correctly
+- ✅ **GDK version conflicts**: Fixed with proper gi.require_version calls
+- ✅ **Presenter singleton patterns**: Fixed with lazy initialization
+- ✅ **Settings manager backend**: Fixed with proper activation sequence
+- ✅ **ATSPI registry startup**: Fixed with deferred D-Bus service initialization
+- ✅ **API naming conventions**: All Orca→Cthulhu API differences resolved
+- 🔄 **Module registration**: Ready for individual managers to register D-Bus commands
+- 🔄 **Plugin integration**: Plugins can expose D-Bus commands using decorators
+
+### **✅ COMPLETED - D-Bus Remote Controller Integration**
+The D-Bus Remote Controller from Orca v49.alpha has been successfully integrated into Cthulhu and is fully functional.
+
+**Root Cause of Issues**: D-Bus service startup timing conflicts with ATSPI registry initialization.
+
+**Solution Implemented**: 
+- Deferred D-Bus service startup using `GObject.idle_add()` after ATSPI event loop is running
+- Fixed all API naming convention differences between Orca and Cthulhu
+
+**Files Modified for D-Bus Integration**:
+- `src/cthulhu/dbus_service.py` (NEW FILE) - Complete D-Bus service port with Cthulhu API fixes
+- `src/cthulhu/input_event.py` - Added RemoteControllerEvent + GDK version fix
+- `src/cthulhu/cthulhu.py` - D-Bus integration + lazy BrailleEvent import + settings manager activation + deferred startup
+- `src/cthulhu/Makefile.am` - Added dbus_service.py to build
+- Multiple presenter files - Converted to lazy initialization pattern
+- `src/cthulhu/keybindings.py` - Fixed GDK version requirement
+- `README-REMOTE-CONTROLLER.md` (NEW FILE) - Complete documentation with examples
+
+**API Fixes Applied**:
+- `debug.print_message` → `debug.printMessage`
+- `script_manager.get_manager()` → `script_manager.getManager()`
+- `get_active_script()` → `cthulhu_state.activeScript`
+- `get_default_script()` → `getDefaultScript()`
+
+### Bug Fixes Applied
+- Fixed circular imports in presenter modules (learn_mode_presenter, notification_presenter, etc.)
+- Added lazy imports for BrailleEvent to break cthulhu.py ↔ input_event.py cycle
+- Fixed GDK version conflicts by adding gi.require_version("Gdk", "3.0") to input_event.py
+- Changed all presenter singleton patterns to lazy initialization to prevent import-time issues
+- Added settings manager activation before loadUserSettings() to fix backend initialization
+
+### **Commands for Analysis**
+```bash
+# Compare specific features between projects
+diff -r /home/storm/devel/cthulhu/src/cthulhu /home/storm/devel/orca/src/orca
+
+# Test Orca's new features
+cd /home/storm/devel/orca && meson setup _build && meson compile -C _build
+
+# Test D-Bus interface
+# (requires running Orca instance with D-Bus support)
