/**
 * 验证「更多」→「政策列表」侧边栏的纯逻辑：去重、排序、关键词过滤。
 *
 * 注：侧边栏列的是**本条回答里的政策**（用户 2026-09-18 调整；此前一度做成
 *     「整个会话跨消息聚合」，那个采集函数已随之删除）。
 *
 * 为什么要单独测：列表要经过「去重 → 排序 → 关键词过滤」三步，
 * 边界容易出错（精简格式的占位符 declaration_item、同分排序抖动、空关键词、
 * 空/脏输入）。这些都是纯逻辑，用断言守住比在浏览器里点便宜得多。
 *
 * 怎么跑（在项目根目录）：
 *   npx esbuild harness/tools/_entry-policy-cards.ts --bundle --format=esm \
 *     --outfile=harness/tools/_policy-cards.mjs
 *   node harness/tools/verify-policy-card-list.mjs
