### 复审修复 K-02
|
||||
|
||||
- 日期：2026-09-30
|
||||
- 原条款：issue #59 及第二轮补充；DEVELOPMENT 第 9 节附录。
|
||||
- 实际做法：ReconnectBackoff 只维护计数 n，mqtt 不再 attempt++ 与 markOffline 双重翻倍；断线后在途发送新 rid 重交；回调成功即置 acked 再发 ack；publishUp 不用 Buffer；keepalive 30；顶号 `taken_over`；0x8B 可重试；connect 超时不永久关闭 Client；logout 把请求失败返回应用；假传输不从 index 导出；示例只打印令牌前缀。未加 Playwright 浏览器冒烟（sdk/js 无该依赖，单测覆盖无 Buffer 的字符串上行）。
|
||||
- 原因：与 K-00 对齐并修 Node 未处理拒绝、浏览器 Buffer、断线永不重交。
|
||||
- 备选方案：沿用 attempt+base 双重翻倍；否决。
|
||||
- 影响：仅 sdk/js。
