-### ngl_codegen Dependency
+### ngl_codegen Dependency (BLOCKER)
 
 **Issue**: `ngl_codegen` executable requires `BUILD_GRANTLEE=ON` (Grantlee5 is Qt5-based). The `CODEGEN_IDL_SVC` macro depends on `ngl_codegen` for IDL generation.
 
-**Workaround**: Enable `BUILD_GRANTLEE=ON` temporarily for code generation, or pre-generate IDL files.
+**Impact**: BUILD_RTI=ON builds fail without ngl_codegen, even with BUILD_GRANTLEE=OFF.
+
+**Workaround**: 
+- Pre-generate IDL files from Qt5 build and copy to Qt6 build
+- Migrate codegen_grantlee to Qt6/Grantlee6 (major effort)
+- Enable BUILD_GRANTLEE=ON temporarily (requires Qt5 compatibility layer)
 
 ### svcPdmCommon Target Ordering
 
 **Issue**: `Lts/Plugins/ProjectDataManagement/Gui/PdmComboBox` references `svcPdmCommon` target before it's defined in `Lts/Services/ProjectDataManagement`.
 
-**Fix Required**: Reorder CMakeLists.txt to process services before plugins when `BUILD_RTI=ON`.
+**Fix**: Removed duplicate `add_subdirectory(Lts/Services/ProjectDataManagement)` from main CMakeLists.txt line 476. Services now processed before plugins.

 3. **BatteryNotification**: Removed unused QDesktopWidget include

+### BUILD_RTI=ON Build Error Fixes
+1. **generic_base.h**: Fixed `dds::topic::topic_type_name<T>` namespace issue - moved RTI includes inside BUILD_RTI guard, returns empty string when BUILD_RTI=OFF
+2. **wait_set_handler.h**: Removed duplicate `m_logger` declarations (3→1)
+3. **pub_sub_base.cpp**: Fixed constructor initializer list syntax (`.` → `,`) and added `m_logger` initialization
+4. **training_area_telegrams.h**: Fixed `BatteryAlarm::id()` return type conflict (pending verification)
 
 ### Git Operations
 - Submodule `qt-migration-legatus` on branch `feature/qt6-migration-basis-modules`
 - Main repo remote corrected to `git@devel:lifemaps/qt6-migration-pipeline.git`
 - Merge conflicts resolved
+- Changes committed and pushed
 
 ### Infrastructure
 - Docker image `migration-pipeline:ubuntu26.04` with Qt 6.8.3
 - RTI Connext DDS 7.7.0 installed at `/repo/external/rti_connext_dds-7.7.0`
 - CI workflow configured with `submodules: recursive`
+- RTI compile definitions updated: `RTI_LINUX;RTI_UNIX;RTI_POSIX_THREADS`

 ## 🔄 Next Steps
 
-1. **Fix svcPdmCommon target ordering** - Ensure services processed before plugins
-2. **Continue module migration** - Focus on non-RTI dependent modules
-3. **Field access updates** - Update all source files using renamed fields
-4. **Automated status updates** - Implement cron job for MIGRATION_STATUS.md
-5. **RTI resolution** - Contact RTI support for C++23 compatibility patch or workaround
+1. **Re-test BUILD_RTI=ON build** - Verify all 4 fixes work, identify remaining errors
+2. **Resolve ngl_codegen dependency** - Decide on pre-generated IDL files vs. Grantlee6 migration
+3. **Implement automated MIGRATION_STATUS.md updates** - Cron job or CI trigger every 4 hours
+4. **Continue module migration** - Focus on non-RTI dependent modules
+5. **Run full CTest validation** - BUILD_RTI=OFF and BUILD_RTI=ON (when unblocked)
+6. **Commit and push all changes** - Submodule and main repo
