1. Run local predeploy gate:
   cd ${PLATFORM_REPO}
   infra/scripts/check-ai-workspace-release-gates.sh

2. Create file backup from mounted NAS share:
   cd ${PLATFORM_REPO}
   NAS_ROOT=${NAS_ROOT} infra/synology/backup-current.sh

3. On Synology, run DB dumps from the backup folder:
   bash /volume1/docker/nodedc-platform/backups/<backup-id>/run-authentik-db-dump-on-synology.sh
   bash /volume1/docker/nodedc-platform/backups/<backup-id>/run-notification-db-dump-on-synology.sh
   bash /volume1/docker/nodedc-platform/backups/<backup-id>/run-ops-agents-db-dump-on-synology.sh
   # Tasker DB dump only if Tasker backend/schema changes are included:
   bash /volume1/docker/nodedc-platform/backups/<backup-id>/run-tasker-db-dump-on-synology.sh

4. Sync source to NAS mount:
   cd ${PLATFORM_REPO}
   NAS_ROOT=${NAS_ROOT} GATEWAY_REPO=${GATEWAY_REPO} infra/synology/deploy-current.sh

5. Apply Ops Gateway first on Synology:
   cd /volume1/docker/nodedc-platform/ops-agents
   sudo /usr/local/bin/docker compose --env-file .env -f docker-compose.synology.yml up -d --build --force-recreate
   curl -fsS http://172.22.0.222:18190/readyz

6. Apply Platform AI Workspace services on Synology:
   cd /volume1/docker/nodedc-platform/platform
   sudo bash apply-current-runtime.sh

7. Verify runtime:
   cd /volume1/docker/nodedc-platform/platform
   sudo bash verify-current-runtime.sh
