/**
 * a2a/exposure.ts — which sessions the operator has chosen to publish as
 * A2A skills.
 *
 * Mirrors inbound.ts's rule: "a route names its session; the payload never
 * does." The AgentCard is a directory a stranger reads before ever
 * proving anything — the first thing a stranger does with a directory is
 * enumerate it — so the card must never list more than the operator
 * explicitly chose. Every persistent session name would be the wrong
 * default: it turns a card fetch into a roster of every project this
 * machine works on. Default is empty; nothing is exposed until the
 * operator runs `aibroker a2a expose <session>`.
