改造前：全仓 6/6 个源文件在 5.1 上解析失败（README 却承诺支持 5.1）。原因是文件是无 BOM 的 UTF-8，而 5.1 没有 BOM 就按 ANSI 代码页解码源码，中文变乱码、全角问号吃掉引号，整块语法塌掉。 现在 28/28 个文件在 5.1 与 7 上都解析零错误，E2E 36 项在 5.1 上全绿。 顺带修掉一个被 5.1 掩盖的缺陷：带 [CmdletBinding()] 的脚本在 5.1 上，param() 默认值里 拿不到 $PSScriptRoot（实测为空串，7 上正常）。于是 Backup.ps1 / Restore.ps1 在 5.1 上不传 路径参数就报错退出 —— 而计划任务恰恰不传。E2E 之所以看不见，是因为它总是显式传路径。 8 处默认值全部移到 param() 之后的解析段，沿用本仓库对 -BackupDir 一直在用的写法。 新增三条可重放的约定，让编码不再是一次性动作： .gitattributes 接管行尾（本机 core.autocrlf=true，会把工作区改成 CRLF 制造伪 diff） .editorconfig 用 charset = utf-8-bom 锁住 BOM tools\Set-SourceEncoding.ps1 是规范化脚本，tools\Invoke-* 之外的任何改动之后都能重放 test.ps1 是唯一验收入口：Encode + Parse + Unit + Smoke + E2E，在 7 与 5.1 上各跑一遍 test.ps1 的 Encode 层直接检查"必须有 BOM"这条规则。加它的原因很实际：实测本仓库用的 编辑工具在保存时会悄悄去掉 BOM，而丢了 BOM 的文件只在 5.1 上出错、在 7 上完全正常， 没有这条检查就会一直漏过去。 已知未修（下一步处理）：5.1 上 Unit 有 6 项、Smoke 有 1 项失败，全部源于测试夹具写 临时文件时没指定编码（5.1 的 Set-Content 默认 ANSI），与产品代码无关。

.SYNOPSIS
|
||
安全描述符（NTFS 属主 / ACL）的测试套件。
|
||
|
||
.DESCRIPTION
|
||
为什么单独一套：这一块的核心契约不是"文件内容对不对"，而是**安全描述符的形状**——
|
||
|
||
* `C:\ProgramData` 下的目录 ACL 里有 `(A;OICIIO;GA;;;CO)`：CREATOR OWNER 是访问
|
||
检查时才替换的占位符，替换成"被检查对象的属主"。只回放 ACE 文本、不恢复属主，
|
||
等于把"谁创建的东西谁有全权"里的"谁"换成跑脚本的账户；
|
||
* 归档格式（.7z）根本不承载安全描述符（7-Zip 的 -sni 只能写进 WIM），
|
||
所以这一块全部靠 <归档名>.acl.json 旁挂文件 + 显式的回放步骤。
|
||
|
||
断言用的"安全指纹"刻意**不含** ACE 的继承标志位与 ID（inherited）标志：
|
||
继承到文件子对象时容器继承位会被系统去掉，而 ID 标志写不回去（不是可写的输入）。
|
||
这两处差异都不改变有效权限，进等式只会制造假失败。
|
||
|
||
跑法：
|
||
.\tests\Run-Pester.ps1 # 会连这一套一起跑
|
||
Invoke-Pester -Path .\tests\BakNRet.Security.Tests.ps1
|
||
#>
|
||
|
||
# 发现阶段（discovery）也会执行文件顶层代码，-Skip: 用到的判据必须在这里算好
