How buying works (when live)

We mint a SpecimenCertificate NFT for a piece — photo, weight, UV coverage, all locked onchain.
Converted pieces get a live BUY button in the vault — pay 70% USDG / 30% GMTS (or the equivalent in RIG + APE discount).
Once bought, the cert is a standard ERC-721 — anyone can list/trade it on OpenSea or any marketplace.
Physical redemption ships US-only (off-chain KYC). Hold the cert forever or redeem for the rock.
Data points (grams, radiation CPM, grade) are updateable onchain with a visible correction history.
