…t ids Walks store/instantiate/mint/verify/transfer for ticket collections, including the seat-hash token_id pattern (from the knowledge-moults deterministic-id approach) that makes double-selling structurally impossible. All four security properties verified end-to-end on junod v27 with cw-nfts v0.19.0. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

What this adds
references/nft-tickets.md— a working pattern for event tickets as cw721 NFTs: one token per seat, counterfeit-proof by construction, resellable by transfer, issuer-gated minting.The core idea (borrowed from the
knowledge-moultsdeterministic-id approach, prop A18c-5): derive thetoken_idfromsha256(artist‖venue‖date‖seat)with no timestamp, so a seat's token id is a mathematical constant — double-selling becomes structurally impossible rather than policy-forbidden. Stockcw721-basethen already enforces all three ticket guarantees; no custom contract needed for a first collection.Verified on juno-1

data_hash(verified ids listed), and an honest "when cw721-base stops being enough" section (redeem-once, royalties, anti-scalping) scoped as deliberate future builds.Rehearsed first on a local single-node devnet; written in the house style of the existing references.
