Query Products are the commercial boundary. MERXAT is the market layer.
A Query Product is a bounded answer or execution contract over the global MERXAT Economic Data Map. Geography, market relation, source and freshness belong to the product capability evaluated at request time; none of them define MERXAT itself.

Inspect canonical availabilityScope is capability-owned
Vertical, geography, market relation, source coverage and availability are product facts. They are not global branding claims and may change only through canonical evidence.
Shared discovery, pricing, payment and delivery
New verticals reuse the same Query Runtime, Pricing, Payment, Delivery, Ledger, rights and provenance authorities. A new product never creates a parallel MERXAT stack.
Discover the catalogue, inspect capability, then decide whether to buy the execution.
The deployed Agent Card and canonical catalogue are the authority for machine-visible products and their current availability.
