+### Added
+- **Portainer Backup Executor** (`portainer_backup_executor.py`) — archives Portainer's
+  own state through its `/api/backup` endpoint. Portainer's BoltDB lives in a Docker
+  volume that the daily config backup does not cover, so losing that volume would take
+  every stack definition with it. Uses the API rather than tarring the live volume, and
+  rejects a 200 whose body is not a readable archive.
