- Archive: \`$archive\`
- Restore target: \`$DATA_DIR\`
- Test container: \`restoretest-gitea\`
- Test endpoints:
  - Web: \`http://127.0.0.1:13000\`
  - SSH: \`127.0.0.1:12222\`
- Result: \`SUCCESS\`

## Checks

- Borg extract into isolated restore-lab: \`ok\`
- HTTP status: \`$status\`
- HTML content: \`Gitea\`
- SSH port: \`$ssh_state\`
- Repository sample: \`$repo_sample\`

## Notes

- Test ran without Traefik and without the productive domain.
- Test data was cleaned after success: \`$([ "$KEEP_DATA" -eq 1 ] && echo no || echo yes)\`
