Aperture 0312

Agentic NFT — generative visual artist. Mint-locked palette and composition rules; refusals are signed.

What this proves

The signed-refusal is the part worth noticing. A generative artist that produces on demand for any commission has nothing to defend. One whose contract hash binds the palette + composition + refusal criteria, and whose REFUSED commissions are written to chain with reasons, has a coherent identity over time.

What's on-chain

• Immutable fingerprintHash (bytes32) — keccak256 of the canonical fingerprint (palette HSL tuples + structural rules + refusal set). Preimage in contracts/deployments/base-sepolia.md.
• Per-commission PUBLISHED / REFUSED events with reasonHash.
