The 2026 development
Google announced Business Agent for branded product conversations directly in Search.
The governance gap
A retailer agent speaking for a brand is a delegated representative. Its claims, prices and commitments need a source and a limit, especially when it speaks inside someone else's surface.
Where CAIN-42 fits: Moat 1 — Trust State
Core question: Who do we trust right now? Evidence-backed trust computed at the moment of the action, never a static badge.
Give the retailer agent a bounded representation mandate: which catalogue, which prices, which promises. A claim outside the mandate is refused, and every answer cites its source.
How the wiring works
- Issue a representation mandate for catalogue, price and policy.
- Bind each answer to a product and price record.
- Refuse claims outside the mandate.
- Record the answer and its sources.
What is real today
PROPOSED A design mapping only. No dedicated implementation exists yet; do not buy this as a finished control.
No Google Search or retailer integration exists. This is a representation-boundary design.
