Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it Hand the buyer to the right agent over Agent-to-Agent (A2A): with an allow decision the order intent goes to the counterparty's agent (envelope + card URL); with a deny, the market agent of the ship-to (the regulator's home page beside it) — a referral, never a sale to a consumer.
