**Data Marketplace.** The customer's accumulated knowledge graph, audit ledger, and trained adapter weights are intended to be saleable assets. The planned marketplace gateway (`service-marketplace`) is intended to expose per-tenant inventory to external buyers. Planned inventory categories include anonymized aggregate queries against the per-tenant graph, trained adapter weights (saleable to other tenants in the same vertical with explicit permission), curated content-wiki material with consent and license terms, and verdict-signed corpus tuples with cryptographic provenance for AI training data buyers.

**Ad Exchange.** The customer is planned to operate as both seller and buyer in a standards-compliant real-time bidding exchange. As seller, the customer's first-party audience — with per-record consent and AI intent classification — is intended to be real-time-bid inventory. As buyer, the customer's adapter may classify their own audience intent to support targeted outbound campaigns. The customer's budget controls the bid.
