chore: 记录改造前基线
改造开始前的完整状态，作为可回退的基点。此提交之后：Pester 175 项、零依赖套件 101 项全绿；PowerShell 5.1 尚不可用（源文件无 BOM）。 包含此前未提交的在制品：安全描述符套件、Hyper-V 实验环境（tools/lab）、agent 约定（AGENTS.md 与 docs/agents）。 .gitignore 增加 *.key / *.pfx：BackupConfig.psd1 的 PasswordFile 此前默认指向仓库内的 baknret.key，一次 git add -A 就会把口令提交进版本库。默认值在后续提交中改为空。

* 本脚本证明的是"**这一批真实归档**解得开，而且解出来的东西和源一致"。
|
||||
|
||||
关键设计：**绝不碰真实目录**。做法是给一份临时名录（SoftwareCatalog），
|
||||
把软件名映射到临时目标目录，于是 Restore.ps1 会把归档解到临时目录，
|
||||
把归档里的顶层条目名映射到临时目标目录，于是 Restore.ps1 会把归档解到临时目录，
|
||||
而不是 ~\.ssh、C:\Programs\... 这些真地方。真实归档本身只被读取。
|
||||
|
||||
归档内的一层名字怎么定，取决于**这个归档是哪种布局**（Backups\ 里两种都有）：
|
||||
* 重构后的新布局：包内顶层是 Slot 名（`<Slot>\<内容>`，文件 Slot 就是名为
|
||||
`<Slot>` 的文件）——manifest 记录的 layouts 里有这个名字；
|
||||
* 重构前的旧布局：包内顶层是源路径的末级名（`<末级名>\...`）——manifest 没有 layouts。
|
||||
本脚本按 manifest 判断，把临时名录的 Slot 名设成归档里**真实存在的那一层名字**，
|
||||
因此新旧布局都能被 Restore.ps1 正常解出来，而不是依赖"解不出来再回退"。
|
||||
|
||||
对拍规则（关键：先把"源变了"和"归档坏了"分开）：
|
||||
* 恢复树里每个文件都必须在活源里存在 —— 否则失败（说明归档里混进了别的东西）；
|
||||
* 内容不一致时看活源文件的修改时间：晚于归档时间 ⇒ 源在备份之后被改过，
|
||||
只提示、不算失败；不晚于归档时间却内容不同 ⇒ 归档或解压有问题，算失败；
|
||||
* 活源里在备份之后新增 / 删掉的文件只提示；
|
||||
* 归档里有、活源里没有的文件：如果它所在的活源目录（或最近的还在的祖辈）
|
||||
的修改时间晚于归档时间 ⇒ 是备份之后从源里删掉的，只提示、不算失败；
|
||||
否则 ⇒ 归档里混进了源里没有的东西，算失败；
|
||||
* 活源里在备份之后新增的文件只提示；
|
||||
* 一个条目一个文件都对不上 —— 失败（多半是空归档，必须点名）。
|
||||
|
||||
真实机器上的归档常常是几周前的，所以"必须和今天逐字节一致"不是合理判据；
