Merchant Layer: Encode GMV/Repurchase/Rebates into Contracts

• On-chain activity templates: Configure “check-in + share + spend” missions; system emits ActivityAnnounce on chain.

• Automated issuance: Upon verification (GPS/POI, spend receipt, anti-sybil thresholds), issue NFT/points/discounts → RewardIssued.

• Measurable ROI: Merchant dashboards show GMV, AOV, repurchase, task completion; closing CampaignSettlement aligns with on-chain anchors for one-click reconciliation.
