Triage note: I couldn't reproduce this as a specific bug because the report doesn't say which kind of .jsc file is involved or what REA did with it, so I'm skipping a fix for now.

.jsc is used by several unrelated formats, and each would need different handling:

V8 code cache / bytenode output (Electron/Node apps): compiled V8 bytecode, tied to the exact V8 version
Cocos2d-x / Cocos Creator script files: usually XXTEA-encrypted JavaScript (sometimes gzip-compressed after decryption)
JavaScriptCore bytecode caches

Could you add:

Where the file comes from (app/engine, and its version if known) and the first ~16 bytes in hex (xxd -l 16 file.jsc, or Format-Hex on Windows);
The exact rea command or MCP tool you ran;
The full output or error REA returned.

分类说明：报告中没有说明是哪一种 .jsc 文件，也没有给出 REA 的具体命令和输出，所以我暂时无法把它复现为具体的缺陷，先不做修复。

.jsc 被多种互不相关的格式使用，需要不同的处理方式：

V8 代码缓存 / bytenode 生成的文件（Electron/Node 应用）：与具体 V8 版本绑定的字节码
Cocos2d-x / Cocos Creator 脚本：通常是 XXTEA 加密的 JavaScript（解密后有时还经过 gzip 压缩）
JavaScriptCore 字节码缓存

请补充：

文件来源（应用/引擎及其版本），以及文件开头约 16 个字节的十六进制（xxd -l 16 file.jsc，Windows 上可用 Format-Hex）；
你运行的 rea 命令或 MCP 工具；
REA 返回的完整输出或错误信息。
