Signal
Loyalty benefits visible to the agent
Whether member pricing and loyalty perks are submitted as structured data rather than shown only after sign-in, so an agent comparing offers can see the price a member would actually pay.
Per-platform status
Where a platform documents relevant behavior, its status and source are shown. Undocumented platforms show "unknown" - honest unknowns, never invented.

How to act on this
If you run a loyalty program with member pricing, submit it as structured loyalty data rather than leaving it behind a login. An agent comparing your offer against a competitor sees the public price unless you give it the member one.

Notes
Only Google documents this today, which is worth stating plainly rather than implying the others read loyalty data quietly. The interesting part for selection is the asymmetry it creates: a member price that only appears after sign-in is invisible at exactly the moment an agent is comparing, so a store can lose a comparison on a price it would never have charged.
