 - 涉及定时器、重试、缓存、前后台切换时，优先保证时间语义闭合，再考虑 UI 表现。
 - 不要把“缓存命中”“回退成功”“页面没报错”误判成“拿到了最新数据”。
 - Codex Chrome 的 Playwright `evaluate` sandbox 和 raw CDP 是不同执行面。需要验证页面内 `fetch`、`XMLHttpRequest`、`DOMParser`、DOM mutation、事件或 `postMessage` 时，有 raw CDP 就优先直接用 `Runtime.evaluate` 和 Network events；只有 raw CDP 不可用或目标浏览器没有所需登录态时，才改用 live DOM/截图/console/page assets、真实 DevTools、Tampermonkey、临时 helper extension 或带 referer 的命令行请求。某个受限 evaluation surface 缺少 API，不代表目标页面不能运行该代码。
+- Codex Chrome 的 `openTabs()`、`claimTab()` 和 page-level CDP 是不同故障层。`openTabs()` 正常而单个 `claimTab()` / `tabs.get()` 挂起时，先按 stale browser-session ownership 处理，不要归因于目标网站或代理节点：同一 `node_repl` kernel 只初始化一次 browser runtime 并复用 binding；claim 超时的结果视为 unknown，禁止重复 claim、重复建 client/session 或继续使用旧 handle。能在同一登录态副本页完成的只读诊断优先用一个 agent-created 临时 tab；只有所有新 tab 也失败时才转入 helper/proxy/CDP 排查。browser 验证未完成时不要重置 kernel，任务结束时不要为普通诊断 tab 设置 handoff/deliverable，让 turn cleanup 释放控制权。详细本机 SOP 见 `~/.dotfiles/knowledge/machines/lizhenhai-macbook-pro-14/LOCAL_PROXY_REFERENCE.md` 的“Codex Chrome `claimTab` 结果丢失与 stale session 占用”。
 - Chrome/CDP 诊断资源必须限制在当前测量范围内：只启用本轮需要的 CDP domain，事件读取必须带过滤条件和数量上限，证据收集完成后销毁页面探针，并关闭本轮启用的所有 domain。不要在持久 `node_repl` 绑定中长期保留大批事件或完整脚本源码。
 - Codex `cua_node` 进程长时间占用超过一个 CPU 核心，并不能证明 userscript 或目标页面仍在忙。应先根据父进程和工作目录确认 PID 归属，检查 JavaScript 事件循环是否真的繁忙，再做短时只读堆栈采样。2026-08-25 的故障中，REPL 事件循环占用只有约 `0.1%`，原生堆栈热点却集中在管道/文件读取、Buffer/UTF-8 转换、typed array 复制和垃圾回收；关闭 CDP domain 后没有恢复，而重置该任务的 `node_repl` 内核会终止高负载 helper，同时保留 Chrome 和 Binance 页面。内核重置会清空所有 REPL 绑定并要求重新连接 Chrome，所以只能在浏览器验证节点完成后使用；清理后必须确认热点 PID 已消失，不要把直接结束 Node 进程作为第一步。
