420 Attention architecture

Canonical Attention state covers consent, campaign lifecycle/economics, proof/nullifier state, reward entitlement and per-campaign Treasury liability.

Raw behavioral telemetry, media, private audience profiles and device data remain off-chain. Sponsors and verifiers do not gain Wallet signing authority or access to arbitrary private data by participating in Attention.

AttentionTreasury protects campaign liabilities from generic treasury spending and only releases unused sponsor funds after campaign closure and cleared reservations.
