What would owning a Void Card actually mean?

Void Cards is a digital collectible concept I am exploring. Before deciding how its Telegram interface might work, I need to make the word "ownership" less vague. A card appearing in someone's collection is a useful starting point, but it does not explain what that person can keep, change or take elsewhere.

I would separate the artwork, the edition and the individual copy. An artwork could have one catalogue ID; each issued copy would need its own ID and owner record. For example, an imaginary catalogue entry called VOID-042 could have a copy numbered 17. Saving its image would not change who the system records as the holder of copy 17. Those are different actions, and the interface should explain the difference.

A central register would also make the project responsible for that record. I would need clear answers about account recovery, corrections, backups and what happens if the service closes. An exported image or collection list could help somebody keep a record, but neither would make the service independent of its operator. That boundary belongs in the explanation of ownership.

My practical check would be to write a small permissions table before building: view, download, display publicly, transfer and use the artwork elsewhere. Each action needs an explicit answer, including any permissions that remain undecided. A memorable name for ownership cannot substitute for telling a collector what the product actually allows.
