生产故障：pi 客户端报 `model "AUTO" returned a completed response with no content`， 重试延迟 8 秒。实测 AUTO 20 次有 2 次返回空 content，全部是 claude-opus-4-8。 根因（直连上游抓包确认）：思考型模型先吐 reasoning_content，max_tokens 小到 思考阶段就把预算用完时，上游返回 200 / finish_reason=length，28 个 chunk 全是 reasoning_content、content 一片空白。runTier 只看 err == nil 就当成功返回， 客户端拿到一个空响应。 修复： - resultIsEmpty：非流式路径把「无 content、无 tool_calls、无 image」的响应当作 slot 失败继续降级。注意 ReasoningContent 不算内容——客户端要的是文本，为 另一个模型的思考阶段扣住请求比降级更糟。 - peekStream：流式路径在出现首个真实内容前缓冲 reasoning 前导，流结束仍无内容 则回报空结果，让 chainDrive 换 slot。缓冲只覆盖思考前导，拿到内容后立即 转发。tool_calls delta 算内容，agent 回合不会被误判。 - 3 条判据 + 3 个变异（恒 false / 恒 true / reasoning 算内容）全部被捕获。 同时修三个 WebUI 布局缺陷（都靠截图而非 DOM 断言发现）： - 插件侧栏项只渲染图标没有标题：btn.innerHTML 只塞 pluginIconHTML(pg.icon)， 与原生页的「图标 + <span>标题</span>」不一致，侧栏是一排无名图标。 - 计费维度表 8 列挤在 465px 卡片里：table-layout:fixed 把每列压到 62px， 23/80 个单元格溢出、数字互相重叠。改为 6 列（token 细分合并为 「输入(新鲜+缓存)」，细分进 title）+ table-layout:auto，实测 0/60 溢出。 - 数字列 word-break:break-all 让每个字符独占一行（USD 0.56 竖排成 U/S/D）， 改 nowrap + 容器横向滚动。
