STEP_034E4C_CLASSIFY_ENDPOINT_LEFTOVERS BLOCK_ACTIVE_OLD_REMAINS
timestamp: 20260708-115441

Final WG Paid endpoint:
- wg-studio.secret-studio.ru:51830

Validation:
- updated_deferred_tasks: 1
- active_final_endpoint_lines: 2
- active_old_endpoint_remaining_lines: 1
- historical_old_endpoint_lines: 13
- running_backend_old_endpoint_lines: 1
- running_backend_final_endpoint_lines: 0
- backend_health_ok_lines: 2
- no_docker_restart_lines: 1
- no_wg_reload_lines: 1
- no_peer_create_lines: 1

Interpretation:
- active source should now be clean
- historical STATUS/backups may retain old smoke endpoints
- running backend still needs controlled restart to load new .env if running_backend_old_endpoint_lines=1

Changes:
- docs cleanup only: DEFERRED_TASKS.md if needed
- no backend restart
- no WG reload
- no peer creation
