+   - `DeploymentLock` prevents concurrent deployments
+   - Apply lock ensures installation integrity
+
+3. **Enhanced Resume Capabilities**
+   - Both PLONDS and legacy update paths supported
+   - Graceful handling of interrupted updates
+
+4. **Improved Grid-Based Editing**
+   - Cell snapping provides consistent UX
+   - Proportional resize mode preserves aspect ratios
+
+5. **CI/CD Reliability**
+   - S3 asset validation prevents bad deployments
+   - Rollback workflow enables quick recovery
+
+### ⚠️ Potential Areas for Attention
+
+1. **Large Code Changes**
+   - 33 files with 3,161 additions / 4,129 deletions
+   - Consider if this should be split into smaller, focused commits
+
+2. **Checkpoint Cleanup Strategy**
+   - Ensure old/invalid checkpoints are periodically cleaned
+   - Consider checkpoint expiration policy
+
+3. **Race Condition Testing**
+   - Verify concurrent update prevention under stress
+   - Test network interruption during checkpoint save
+
+4. **Memory Management**
+   - `UpdateWorkflowService.cs` deletion (-1572 lines) suggests refactoring
+   - Confirm no functionality was lost in the consolidation
