The context
A Gloster canary competition means several hundred birds entered by dozens of breeders across two days — the 2025 edition analysed beforehand counted 476 entries from 34 breeders. Until now everything lived in Excel files and paper forms: the entry list, cage allocation, the judge's ranking, then the results table copied out by hand on prize-giving night. Every re-copy is a chance to introduce an error, and an error in the results is paid for in disputes.
