 ## ✅ Completed Work
 
+### Session 013: VideoOverlayManagement Logger Fixes
+
+#### Fixed Files (6 files changed, ~40 insertions, ~20 deletions)
+
+1. **Lts/Services/VideoOverlayManagement/logger.cpp**
+   - Added `#if BUILD_RTI` guards around logger initialization
+   - Replaced `NGLLoggerBootstrap` with `NGL::getMemoryLogger()` for BUILD_RTI=OFF
+   - **Impact**: Clean compilation without RTI dependencies
+
+2. **Lts/Services/VideoOverlayManagement/avs_interface.cpp**
+   - Fixed logger initialization to use `NGL::getMemoryLogger()`
+   - Fixed Qt6 signal syntax: `error` → `errorOccurred` (line 57)
+   - **Impact**: Qt6 compatibility for TCP socket error handling
+
+3. **Lts/Services/VideoOverlayManagement/main_handler.cpp**
+   - Fixed logger initialization pattern
+   - **Impact**: Consistent logger usage across module
+
+4. **Lts/Services/VideoOverlayManagement/handler_overlays.cpp**
+   - Fixed logger initialization
+   - **Impact**: BUILD_RTI=OFF compatibility
+
+5. **Lts/Services/VideoOverlayManagement/handler_infrastructure_data.cpp**
+   - Fixed logger initialization
+   - **Impact**: BUILD_RTI=OFF compatibility
+
+6. **Lts/Services/VideoOverlayManagement/handler_participant_data.cpp**
+   - Fixed logger initialization
+   - **Impact**: BUILD_RTI=OFF compatibility
+
+#### Build Results
+
+```
+✅ BUILD_RTI=OFF: VideoOverlayManagement compiles successfully
+   - All logger initialization patterns fixed
+   - Qt6 signal syntax corrected (error → errorOccurred)
+✅ BUILD_RTI=ON: Pending validation
+```
+
+#### Key Technical Details
+
+**INGLLogger Interface Pattern**:
+- `INGLLogger` is an abstract interface with no static `instance()` method
+- Created externally via `NGLLoggerBootstrap` or `NGL::getMemoryLogger()`
+- For BUILD_RTI=OFF stubs: Use `NGL::getMemoryLogger()` which returns `INGLLogger&`
+- Pattern: `auto& logger = NGL::getMemoryLogger();` instead of `NGLLoggerBootstrap::getNGLRootLogger()`
+
+**Qt6 Signal Syntax**:
+- `QTcpSocket::error` signal renamed to `errorOccurred` in Qt6
+- Connection syntax: `connect(socket, &QTcpSocket::errorOccurred, ...)`
+- May require `QOverload` for const member function pointer
