NOW: 读取 ../field-journal/precedent-reverse.mdNOW: 确认目标是浏览器扩展（crx/xpi/解压目录），不是普通网页 JS（普通 → js-reverse/）NEXT: 解压扩展；读 manifestACT: 权限面 → 后台脚本 → 网络/存储钩子□ crx 解压 / 从 profile 取扩展目录
□ manifest.json：permissions、host_permissions、background、content_scripts
□ 评估过度权限（<all_urls>、webRequest、debugger）
□ service_worker / background 入口
□ content_script 注入点与世界（isolated）
□ chrome.storage / IndexedDB 密钥
□ 与 `js-reverse` 相同：Observe 网络与消息传递（runtime.sendMessage）
□ 开发者模式加载解压目录
□ chrome://extensions 检查错误
□ DevTools 附加 service worker
□ 必要时 Frida/浏览器 CDP（jshookmcp）
