修复（P0） - 退出码：改用 .NET Process 继承控制台启动外部命令。Start-Process -PassThru 的 ExitCode 在 PowerShell 7.7.0-preview.4 上恒为 $null，会把成功的压缩判成失败， 并让 "exit 2 -> 删档重试" 的自愈分支永远不可达。 - BackupList.txt 解析：先按第一个 :: 切开再处理引号，修正整行被引号包住时 排除表被吞进路径的问题（该条目此前被静默跳过，其 2.8 GB 归档成了孤儿）。 - 排除分隔符同时接受 , 与 ;：此前解析器只认 ; 而清单里写的是 ,， 等于所有排除规则都没生效。 - 7z 排除参数不再嵌引号，含空格的模式自动转成 ?：旧写法 -x!"路径" 会让引号 成为模式的一部分，导致排除对所有条目都失效。 加固（P1） - 先写临时归档 -> 7z t 校验 -> 原子替换，中断不再污染正式归档。 - 放弃 7z 的更新模式 u：固实压缩下收益极小，却让排除规则改动与已删文件 永远进不了归档。 - 新增 Backups/manifest.json 与 logs/*.log，跳过/失败有据可查。 - 结尾按失败数 exit；恢复支持 -WhatIf / -DryRun / -VerifyOnly / -Only。 - 恢复优先用 manifest 定位归档，并精确比较 BaseName（不再用 -Filter 通配）。 - 修正 tar 分支用 $LASTEXITCODE 判断成功与否的缺陷。 - 有警告（文件被占用）时拒绝用不完整的归档覆盖完整归档，需显式 -AcceptWarnings。 策略与安全（P2） - Edge 条目加排除规则：解压后 4.22 GB 中 3.79 GB 是可再生的缓存/遥测/扩展本体， 保留书签、密码、偏好、历史与站点数据。 - 可选 7z 加密（@encrypt 标记或全局开关），取不到口令时明确失败，绝不写明文。 - 磁盘空间守卫：放不下就跳过该条目，低于阈值告警。 工程化（P3） - 新增 BackupConfig.psd1、README.md、.gitignore。 - tests/Run-Tests.ps1（32 项）与 tests/Run-E2E.ps1（16 项端到端验收）。 - tools/Register-BackupTask.ps1 注册每日计划任务。 - 归档命名算法保持不变，已有归档不会失联。

.SYNOPSIS
|
||
按 BackupList.txt 执行备份。
|
||
|
||
.DESCRIPTION
|
||
与旧版相比的核心变化：
|
||
|
||
1. 退出码可靠 —— 不再用 Start-Process -PassThru（在 PowerShell 7.7.0-preview.4 上
|
||
ExitCode 恒为 $null，会把成功的压缩判成失败），改用 Invoke-ExternalCommand。
|
||
2. 先写临时归档 → 校验 → 原子替换。中断或断电只会留下 .tmp 文件，
|
||
不会污染正式归档；也不会再出现"半个归档被下次增量续写"的情况。
|
||
3. 不再使用 7z 的 u（更新）模式。7z 默认是固实压缩，u 本来就要重压大部分数据，
|
||
收益极小，却让排除规则和删除操作永远无法生效（旧归档里会一直留着已删文件）。
|
||
现在每次都从零打包，于是"排除规则改动"和"源里删掉的文件"都能真正反映到归档。
|
||
4. 每个条目写进 manifest.json：源、归档、时间、退出码、校验结果、失败原因。
|
||
跳过和失败从此有据可查，而不是只剩一行滚过去的控制台告警。
|
||
5. 结尾按失败数 exit，并写日志文件，计划任务能正确判断成败。
|
||
6. 磁盘空间守卫：放不下就拒绝该条目，低于阈值则告警。
