 ## ✅ Completed Work
 
+### Session 010: LtsUtilsCore Include Path and BUILD_RTI Guards
+
+#### Fixed Files (3 files changed, 4 insertions, 1 deletion)
+
+1. **Lts/Common/LtsUtils/LtsUtilsCore/CMakeLists.txt**
+   - Fixed include path from `/..` to `/../..` for both `LtsUtilsCoreHeaderOnly` and `LtsUtilsCore` targets
+   - **Impact**: BuildingControlUnit and other modules can now find `LtsUtils/LtsUtilsCore/qpoint3d.h`
+
+2. **Lts/Services/RoutingServiceNG/session_handler.h**
+   - Added `#if BUILD_RTI` guard around `#include "dds_connector.h"` (line 17)
+   - **Impact**: BUILD_RTI=OFF builds no longer fail on missing RTI headers
+
+3. **Lts/Services/RoutingServiceNG/data_writer_task.h**
+   - Removed `override` specifier from stub methods in `#else /* !BUILD_RTI */` block (line 40)
+   - **Impact**: Stub methods compile correctly when base class interface is not available
+
+#### Build Results
+
+```
+✅ BUILD_RTI=OFF: 0 errors (validated previous session)
+✅ BUILD_RTI=ON: BuildingControlUnit now compiles successfully
+   - BuildingControlCommon: logger.cpp, settings.cpp, mocs_compilation.cpp ✅
+   - LtsUtilsCore: qpoint3d.h include path resolved ✅
+⚠️  Remaining errors are EXTERNAL DEPENDENCIES (not migration issues):
+   - IsmDataPluginInterface: linker error -lsvcIsmCommon (external lib not in Docker)
+   - IsmShared: linker error -lsvcIsmCommon (external lib not in Docker)
+```
