 ## Completed ✅
 
+- ✅ **Systemd Service Name Consistency**: Renamed and updated all references from `apt-ostree.service` to `apt-ostreed.service` for correct systemd and D-Bus integration
+- ✅ **D-Bus Signal Emission**: Fixed all dbus-next signal emission calls to use direct function calls instead of `.emit()`, resolving 'function object has no attribute emit' errors
+- ✅ **apt-layer.sh Integration**: Updated apt-layer.sh and related scriptlets to use the correct service name and ensure proper daemon status detection and management
+- ✅ **End-to-End D-Bus Testing**: Successfully tested D-Bus method/property calls and signal emission via busctl and apt-layer.sh, confirming full integration and correct daemon operation after VM reboot and service migration

 ### Daemon Integration (COMPLETED)
 - ✅ **D-Bus Interface**: Complete D-Bus interface implementation with sysroot and transaction interfaces
 - ✅ **Import Resolution**: Fixed all Python import conflicts and package structure issues

 ## [Unreleased]
 
 ### Added
-- **Project Relocation Planning**: Added TODO for moving project from $HOME to /opt
-  - Planned relocation from /home/joe/particle-os-tools to /opt/particle-os-tools
-  - Will eliminate need for ProtectHome=false in systemd service for better security
-  - Low priority task to improve security posture while maintaining functionality
-  - Includes updating path references, configuration files, and documentation
-
 - **Enhanced Logging System**: Comprehensive logging enhancement with advanced features
   - **Advanced Log Rotation**: Implemented size-based, time-based, and hybrid rotation strategies
     - Size-based rotation with configurable file size limits
@@ -115,11 +109,10 @@
   - Daemon now properly handles concurrent async operations without blocking
   - All package management methods (InstallPackages, RemovePackages, etc.) now work correctly
 
-- Fixed duplicate D-Bus handler/daemon instance bug that caused 'already a handler' errors and multiple daemon processes
-- Enforced single-instance logic via systemd and D-Bus name ownership
-- Confirmed only one daemon process runs at a time, even when triggered by apt-layer.sh
-- Integration with apt-layer.sh no longer spawns extra daemons
-- Successfully broke the loop and ready for full D-Bus integration testing
+- **Systemd Service Name Consistency**: Renamed and updated all references from `apt-ostree.service` to `apt-ostreed.service` for correct systemd and D-Bus integration.
+- **D-Bus Signal Emission**: Fixed all dbus-next signal emission calls to use direct function calls instead of `.emit()`, resolving 'function object has no attribute emit' errors.
+- **apt-layer.sh Integration**: Updated apt-layer.sh and related scriptlets to use the correct service name and ensure proper daemon status detection and management.
+- **End-to-End D-Bus Testing**: Successfully tested D-Bus method/property calls and signal emission via busctl and apt-layer.sh, confirming full integration and correct daemon operation after VM reboot and service migration.
 
 ### Added
 - **Systemd Service Integration**: Complete systemd service setup for apt-ostree daemon
