// [zh] 日历附件解压容器逃逸
// 27.2 将 _UnzipArchive（288 B，无任何限制）替换为 _UnzipArchiveWithLimits（2040 B），并新增 _CalUnzipEntryDestinationPath
// / _CalUnzipParentIsContained / _CalUnzipTrackTopLevelPath 与 isSymbolicLinkAtURL。ICS 解析器本身未作改动 ——
// 修复全部位于附件归档的解压遏制层。
//
// [en] Calendar attachment extraction containment
// iOS 27.2 replaces _UnzipArchive (288 B, no limits at all) with _UnzipArchiveWithLimits (2040 B)
// and adds _CalUnzipEntryDestinationPath / _CalUnzipParentIsContained / _CalUnzipTrackTopLevelPath
// plus isSymbolicLinkAtURL. The ICS parser itself is untouched — the whole fix sits in the attachment
// archive extraction containment layer.
// ── 判别 / oracle ──
// 应用侧可以验证 CalendarFoundation 的类与方法是否可见，以及本进程里 libarchive 的路径穿越是否被拦住（用 ../ 名字的归档试）。
