- Move SystemLogger implementation to utils/logger_manager.py (pure utility, no deps) - services/logger_manager.py becomes a backward-compat re-export shim - database/manager.py and database/vendor_manager.py now import from utils layer - Extract get_dashboard_stats() to services/dashboard_service.py - services/task_runner.py no longer imports from routes layer - routes/dashboard_routes.py get_dashboard_stats() delegates to service layer Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
