Certificate of Ownership
Every copy of the library can be registered to a name and a number. The certificate seal is sha256(library seal | owner | copy | date) — the same derivation certify.py uses inside the zip, so anyone holding the download can re-derive yours and confirm it. It is a receipt of provenance. It unlocks nothing, and nothing here is copy-protected.
One certificate per name, per edition. Names appear in the public register below — use a pen name if you'd rather not.
Dry run · staging mint
Derives the exact certificate a real mint would produce — same seal derivation, same copy number — and writes nothing to the ledger. Leave the fields blank to preview the next copy in sequence.
