/**
 * The capability catalogue must never promise something the adapter cannot answer.
 *
 * Every question offered in the topic browser is one tap away from being sent, so a suggestion that
 * lands on the fallback is worse than showing nothing: the app would be confidently advertising a
 * capability it does not have, which is the exact failure mode this product argues against. These
 * tests send every entry through the real adapter in BOTH languages, so the rule is enforced by the
 * machine instead of by whoever last edited the list.
