// [zh] Mach-O 解析器自检
|
|
// 对系统卷上的几个真实二进制跑一遍头解析：架构、类型、平台、最低系统、SDK、加密状态、链接库、rpath。加密状态是这一整套里最有信息量的字段 —— 系统框架 cryptid 为 0，第三方
|
|
// App 的二进制不是。

|
// [en] Mach-O parser self-test
|
|
// Runs header parsing over several real binaries on the system volume: architecture, type, platform,
|
|
// minimum OS, SDK, encryption state, linked libraries, rpaths. Encryption state is the most informative
|
|
// field in the whole set — system frameworks have cryptid 0, third-party app binaries do not.
|
|
// ── 判别 / oracle ──
|
|
// 同时跑我自己写的解析器和 MachOInspector，两个结果应该一致。
