## Notes

- **Session flow**: MRW keeps the number in an ASP session, so each lookup is a short sequence (about two seconds, run one at a time in a batch).
- **Purged history**: when MRW has dropped the scans but kept the final state, the result has that one event.
- **Local time only**: Spain and Portugal are an hour apart and the page prints no zone, so `timestamp` is `null`. Descriptions are in Spanish.
