+
+## Integration Points
+
+### Publications Tab
+- Validation section with component filter dropdown
+- ValidationButton trigger
+- ValidationSummary compact display
+- ValidationReport detailed modal
+
+### Services
+- GitHub service integration (file fetching)
+- Staging ground service integration (local files)
+- DAK compliance service bridge (existing validators)
+- XSD validation service (schema validation)
+
+### React Hooks
+- `useValidation()` - Main validation hook with repository context
