【需要登录】【何时用】get_chain_anchor 某一类只给了一屏预览，用户想再看几个时。按 groupId 单独翻那一组。
【组合链】get_chain_anchor 拿 groupId + direction → 本工具翻页 → items[].id 再喂回 get_chain_anchor 就是下一跳；items[].id（type=user）→ get_creator → start_conversation。
【口径/坑】
· **游标是 HMAC 签名的、且绑定 profileVersion**：nextCursor 必须**原样透传**，改一个字符就 400 invalid_cursor。
· 撞 409 chain_cursor_stale = 锚点画像在你翻页期间变了（他改了资料/产品）。**别拿同一个游标重试**，重新调 get_chain_anchor 从第一页来。
· 同样**真花钱**（每翻一页都是一批 LLM 成对审核），同样别循环翻到底。
· warming=true / supply=warming 时空批只代表「还没判完」；supply=gated 是「判过了，没有一个能证明存在真实价值流」；supply=none 才是「站内确实没有这类主体」。
· pageInfo.total 经常是 null（不穷举 LLM 判定就得不到精确总数）——**null 就说不知道，绝不拿当前页长度冒充总量**。
