Subject: [PATCH 01/36] fix(ci): fix Docker GHCR tags, add GUI to macOS/Windows
 releases, bundle OpenSSL DLLs on Windows

- fix docker-bake.hcl: add REGISTRY variable (ghcr.io/airprofly/backer)
  so HCL generates correct GHCR tags; drop :latest tag per request
- fix docker-publish.yml: remove redundant --set override, let HCL
  resolve REGISTRY from env var directly
- fix publish-release.yml: install OpenSSL + Qt6 on macOS (brew) and
  Windows (choco), enable BUILD_GUI=ON, package backer-gui alongside
  backer-cli
- fix publish-release.yml: bundle libcrypto-3-x64.dll and
  libssl-3-x64.dll into Windows ZIP to fix "missing DLL" popup
- fix FetchQt6.cmake: add macOS/Windows platform detection (aqtinstall),
  fix Qt6_DIR path to use detected arch instead of hardcoded gcc_64

Subject: [PATCH 12/36] fix(ci): use correct Qt6 arch identifier for Windows

Qt 6.5.0 provides win64_msvc2019_64, not win64_msvc2022_64.
MSVC 2019 binaries are ABI-compatible with MSVC 2022.

Also pass -DQt6_DIR explicitly to cmake for reliable discovery.

Subject: [PATCH 25/36] fix(ci): reset PowerShell exit code after windeployqt
 warning

windeployqt returns non-zero on translation file issues but
successfully copies all DLLs. Reset LASTEXITCODE to 0 to prevent
PowerShell from propagating the error.

windeployqt only bundles Qt dependencies. Manually copy
libcrypto-3-x64.dll and libssl-3-x64.dll from choco's OpenSSL
installation to ensure the runtime has the correct SSL libraries.

-```
-
-**说明**
-
-默认模式。Backer 将源目录递归扫描，在目标位置重建完整的目录结构，每个文件逐一复制：
-
-```text
-源目录                          备份目录

-  Skipped: 0
-  Time:    123 ms
-```
+---
 
-**示例**
+## 目录镜像备份（基本要求 40分）
+支持目录树的完整备份与还原，包含普通文件和目录结构。
 
 ```bash
-# 备份项目目录
+rm -rf data/backup data/restore
 ./build/backer-cli backup data/source data/backup
-
-# 还原备份
+ls -l data/backup
 ./build/backer-cli restore data/backup data/restore
+ls -l data/restore
 ```
 
 ---
 
-### 特殊文件处理
-
-Backer 使用 POSIX `lstat()` 检测文件类型，支持以下特殊文件的完整备份与还原：
-
-| 类型 | CLI 标识名 | 说明 |
-|------|-----------|------|
-| 符号链接 | `symlink`, `link`, `l` | 备份链接目标路径，还原时重建软链接 |
-| 命名管道 | `fifo`, `pipe`, `p` | 通过 `mkfifo()` 创建 |
-| 块设备 | `block`, `blockdev`, `b` | 通过 `mknod()` 创建，记录设备号（major/minor） |
-| 字符设备 | `char`, `chardev`, `c` | 通过 `mknod()` 创建，记录设备号 |
-| Socket | `socket`, `sock`, `s` | 备份条目存在，还原时创建空占位文件 |
-
-> **注意**：创建块/字符设备节点需要 root 权限。非 root 运行时相关设备会被跳过并记录警告。
-
----
-
-### 元数据保留
-
-Backer 自动保留并还原以下文件元数据：
-
-| 元数据 | 说明 | 还原条件 |
-|--------|------|----------|
-| 属主 (UID/GID) | 文件所有者和所属组 | 需要 `CAP_CHOWN` 能力（root） |
-| 权限 (mode bits) | rwx + setuid/setgid/sticky | 始终还原（symlink 在 Linux 上跳过） |
-| 访问时间 (atime) | 最后访问时间（纳秒精度） | 始终还原 |
-| 修改时间 (mtime) | 最后修改时间（纳秒精度） | 始终还原 |
-| 变更时间 (ctime) | 状态变更时间 | 记录但不还原 |
-
-元数据通过 JSON 文件（`backer_metadata.json`）存储在备份目录中。
-
----
-
-### 筛选器（6 维度）
-
-筛选选项仅适用于 `backup` 子命令，`restore` 时不做筛选。
-
-**命令形式**
-
-```text
-backer-cli backup <source> <destination> [--include-* ...] [--exclude-* ...]
-```
-
-**相关选项**
-
-| 维度 | 选项 | 说明 | 参数格式 |
-|------|------|------|----------|
-| 路径 | `--include-path <GLOB>` | 仅包含匹配路径 glob 的文件（可重复） | `"src/*.cpp"` |
-|      | `--exclude-path <GLOB>` | 排除匹配路径 glob 的文件（可重复） | `"build/*"` |
-| 类型 | `--include-type <TYPE>` | 仅包含指定类型的文件（可重复） | `file` / `dir` / `symlink` / `fifo` / `block` / `char` / `socket` |
-|      | `--exclude-type <TYPE>` | 排除指定类型的文件（可重复） | 同上 |
-| 名称 | `--include-name <GLOB>` | 仅包含匹配文件名 glob 的文件（可重复） | `"*.txt"` |
-|      | `--exclude-name <GLOB>` | 排除匹配文件名 glob 的文件（可重复） | `"*.tmp"` |
-| 时间 | `--mtime-before <UNIX_TIME>` | 排除修改时间在此时间戳**之后**的文件 | Unix 秒级时间戳 |
-|      | `--mtime-after <UNIX_TIME>` | 排除修改时间在此时间戳**之前**的文件 | Unix 秒级时间戳 |
-| 尺寸 | `--size-min <BYTES>` | 最小文件大小（字节） | 数字 |
-|      | `--size-max <BYTES>` | 最大文件大小（字节） | 数字 |
-| 属主 | `--owner <USER>` | 仅包含指定用户拥有的文件 | 系统用户名 |
-
-> **筛选逻辑**：相同维度的多个 `--include-*` 规则为**或**（OR）关系——满足任一即通过该维度；不同维度的规则为**与**（AND）关系——所有维度都必须通过。
-
-筛选器在目录遍历之后、写入存储之前应用，支持 6 种独立的筛选维度：
-
-#### 1. 路径匹配
-
-基于相对路径的 glob 匹配，使用 `fnmatch` 的 `FNM_PATHNAME` 语义——`*` 不匹配路径分隔符 `/`：
+## 文件类型支持（10分）
+支持符号链接、管道（FIFO）、字符设备、块设备等特殊文件的备份与还原。
 
 ```bash
-# 仅备份 subdir 目录下的文件
-./build/backer-cli backup data/source data/backup --include-path "subdir/*"
-
-# 排除 subdir 目录
-./build/backer-cli backup data/source data/backup --exclude-path "subdir/*"
+rm -rf data/backup data/restore
+./build/backer-cli backup data/source data/backup
+ls -l data/backup
+./build/backer-cli restore data/backup data/restore
+ls -l data/restore
 ```
 
-#### 2. 文件类型
-
-```bash
-# 排除 FIFO 管道
-./build/backer-cli backup data/source data/backup --exclude-type fifo
-
-# 排除符号链接
-./build/backer-cli backup data/source data/backup --exclude-type symlink
-
-# 仅备份目录和普通文件
-./build/backer-cli backup data/source data/backup --include-type dir --include-type file
-```
+---
 
-#### 3. 文件名
+## 元数据保留（10分）
 
-基于文件名（不含路径部分）的 glob 匹配：
+| 元数据 | 还原条件 |
+|--------|----------|
+| 属主 (UID/GID) | 需要 root |
+| 权限 (mode bits) | 始终还原 |
+| 访问/修改时间 | 始终还原（纳秒精度） |
 
 ```bash
-# 仅备份 .txt 文件
-./build/backer-cli backup data/source data/backup --include-name "*.txt"
-
-# 排除 .fifo 文件
-./build/backer-cli backup data/source data/backup --exclude-name "*.fifo"
+rm -rf data/backup data/restore
+./build/backer-cli backup data/source data/backup
+ls -l data/backup
+./build/backer-cli restore data/backup data/restore
+ls -l data/restore
 ```
 
-#### 4. 修改时间
+---
 
-基于 Unix 时间戳筛选：
+## 筛选器（6维度各3分，共18分）
 
 ```bash
-# 仅备份 2026 年 7 月 1 日之后修改过的文件
-./build/backer-cli backup data/source data/backup --mtime-after 1818000000
-
-# 排除最近 7 天内修改过的文件
-./build/backer-cli backup data/source data/backup --mtime-before $(($(date +%s) - 7*86400))
+./build/backer-cli backup <source> <dest> [--include-* ...] [--exclude-* ...]
 ```
 
-> `--mtime-after` 是包含下限，`--mtime-before` 是排他上限（修改时间在此之前的文件保留）。可用 `$(date +%s)` 获取当前 Unix 时间戳。
-
-#### 5. 文件大小
+| 维度 | 选项 | 示例 |
+|------|------|------|
+| 路径 | `--include-path <GLOB>` | `"src/*.cpp"` |
+|      | `--exclude-path <GLOB>` | `"build/*"` |
+| 类型 | `--include-type <TYPE>` | `file`, `dir`, `symlink`, `fifo` |
+|      | `--exclude-type <TYPE>` | 同上 |
+| 名称 | `--include-name <GLOB>` | `"*.txt"` |
+|      | `--exclude-name <GLOB>` | `"*.tmp"` |
+| 时间 | `--mtime-after <TIME>` | 排除此时间前的文件（Unix 时间戳或 YYYY-MM-DD） |
+|      | `--mtime-before <TIME>` | 排除此时间后的文件（同上） |
+| 尺寸 | `--size-min <BYTES>` | 最小字节数 |
+|      | `--size-max <BYTES>` | 最大字节数 |
+| 属主 | `--owner <USER>` | 仅指定用户的文件 |
 
-按字节数筛选：
+**示例**
 
 ```bash
-# 仅备份 10 字节以上的文件（排除空小文件）
-./build/backer-cli backup data/source data/backup --size-min 10
-
-# 排除 100 字节以上的大文件
-./build/backer-cli backup data/source data/backup --size-max 100
+# 仅备份 .txt 文件                                         ← 名字筛选（3分）
+rm -rf data/backup
+./build/backer-cli backup data/source data/backup --include-name "*.txt"
+ls -l data/backup
 
-# 备份大小在 10 到 100 字节之间的文件
-./build/backer-cli backup data/source data/backup --size-min 10 --size-max 100
-```
+# 排除符号链接和设备文件                                     ← 类型筛选（3分）
+rm -rf data/backup
+./build/backer-cli backup data/source data/backup --exclude-type symlink --exclude-type block
+ls -l data/source
+ls -l data/backup
 
-> `--size-min 0` 为默认值，表示不设下限。如要筛选空文件，可指定 `--size-min 1`。
+# 仅备份 10 字节以上的文件（doc.txt 13B 保留，sub/file.txt 7B 排除）← 尺寸筛选（3分）

-### Tar 打包
-
-**相关选项**
-
-| 选项 | 说明 | 可选值 |
-|------|------|--------|
-| `--pack tar` | 启用归档模式，生成 `.tar` 文件 | 还原时同理：`--pack tar` |
-
-**说明**
-
-`--pack tar` 启用归档模式，将备份内容打包为 POSIX ustar 格式的 `.tar` 文件。
-
-支持的 tar 条目类型：普通文件、目录、符号链接、FIFO、块设备、字符设备。
-
-**格式细节**：
-
-| 特性 | 支持情况 |
-|------|----------|
-| 格式标准 | POSIX ustar（`magic = "ustar\0"`） |
-| 最大路径长度 | 255 字符（name=100 + prefix=155） |
-| 数据块大小 | 512 字节，末尾零填充对齐 |
-| 文件大小 | 支持超大型文件（12 位八进制，最大 8 GB） |
-| 校验和 | 每个头部包含校验和验证 |
-| 归档尾标记 | 两个全零的 512 字节块 |
-| 属主名/组名 | 记录在头部（各 32 字符） |
-
-> 元数据直接编码在 tar 头部各字段中。
-
-**示例**
+## 打包（Tar/Zip）（每种10分，共20分）
 
 ```bash
-# 打包备份与还原
-./build/backer-cli backup data/source data/backup.tar --pack tar
+# Tar 打包
+rm -rf data/backup data/restore
+./build/backer-cli backup data/source data/backup --pack tar
+ls -lh data/backup.tar
 ./build/backer-cli restore data/backup.tar data/restore --pack tar
+ls -l data/restore
 
-# 快速快照：仅备份目录和符号链接（不备份文件内容）
-./build/backer-cli backup data/source snapshot.tar --pack tar \
-    --include-type dir --include-type symlink
-```
-
----
-
-### Zip 打包
-
-**相关选项**
-
-| 选项 | 说明 | 可选值 |
-|------|------|--------|
-| `--pack zip` | 启用归档模式，生成 `.zip` 文件 | 还原时同理：`--pack zip` |
-
-**说明**
-
-`--pack zip` 启用归档模式，将备份内容打包为标准 Zip 格式的 `.zip` 文件。
-
-基于 miniz 库实现，支持 DEFLATE 压缩。
-
-支持的条目类型：普通文件、目录、符号链接、FIFO、块设备、字符设备。
-
-**特殊文件处理**：
-
-Zip 格式不原生支持特殊文件类型，Backer 通过在归档中嵌入元数据条目来实现完整还原：
-
-| 条目类型 | Zip 中的表示 |
-|----------|-------------|
-| 普通文件 | 标准 Zip 条目（DEFLATE 压缩） |
-| 目录 | Zip 目录条目（名称以 `/` 结尾） |
-| 符号链接 | 文件内容为目标路径，由元数据标记为符号链接 |
-| FIFO/设备/Socket | 零字节占位条目，由元数据标记实际类型 |
-
-所有元数据（属主、权限、纳秒精度时间戳、设备号等）存储在归档根目录的 `.backer_zip_meta` 条目中。
-
-**格式细节**：
-
-| 特性 | 支持情况 |
-|------|----------|
-| 格式标准 | 标准 Zip（PKZIP 2.0+） |
-| 压缩算法 | DEFLATE（默认级别） |
-| 最大路径长度 | 不限（Zip 本身不限制路径长度） |
-| 文件大小 | 不限（Zip64 支持 4 GiB+） |
-| 数据完整性 | CRC-32 校验（Zip 条目级） |

+# Zip 打包
+rm -rf data/backup data/restore
+./build/backer-cli backup data/source data/backup --pack zip
+ls -lh data/backup.zip
 ./build/backer-cli restore data/backup.zip data/restore --pack zip
-
-# 仅备份特定类型的文件
-./build/backer-cli backup data/source data/backup.zip --pack zip \
-    --include-type file --include-type dir
-
-# 与筛选器组合
-./build/backer-cli backup data/source data/backup.zip --pack zip \
-    --include-name "*.txt" --include-name "*.md"
-```
-
----
-
-### 图形界面（GUI）
-
-Backer 提供基于 Qt 6 的图形用户界面，macOS 简约风格，功能等价于 CLI 的所有备份/还原操作。
-
-#### 构建
-
-```bash
-# 自动下载 Qt6 预编译二进制（首次需联网，数分钟）
-cmake -B build -DBUILD_GUI=ON
-cmake --build build -j$(nproc)
-./build/backer-gui
+ls -l data/restore
 ```
 
-启动后先显示启动画面（盾牌+箭头插图），随后进入主界面。
-
-#### 功能说明
-
-| 页面 | 功能 |
-|------|------|
-| 备份 | 选择源/目标目录，配置打包/压缩/加密选项，可视化筛选条件编辑，实时进度条和日志 |
-| 还原 | 选择备份源（文件或目录），配置解压/解包选项，保留元数据/特殊文件选项 |
-| 定时任务 | 添加/编辑/删除定时备份任务（Cron 表达式），空状态插图引导，任务列表管理 |
-| 设置 | 默认路径、默认压缩/加密偏好、日志级别、并发线程数，通过 QSettings 持久化 |
-
 ---
 
-### 压缩解压
-
-备份归档（`.tar` / `.zip`）后可叠加压缩以节省存储空间，还原时先解压再解包。支持三种算法：
-
-| 算法 | 选项值 | 文件后缀 | 级别范围 | 默认级别 | 特点 |
-|------|--------|----------|----------|----------|------|
-| gzip | `gzip` | `.gz` | 0–9 | 6 | 通用、解压快 |
-| zstd | `zstd` | `.zst` | 1–22 | 3 | 日常备份首选，速度快 |
-| LZMA | `lzma` | `.xz` | 0–9 | 6 | 压缩比最高，速度较慢 |
-
-> 压缩作用于**打包后的归档文件**（而非单个文件），因此需配合 `--pack` 使用。
-
-#### 命令
+## 压缩解压（每种10分，共30分）
 
 ```bash
-# 备份 → 打包 (tar) → 压缩 (gzip) 产出 data/backup.tar.gz
+# gzip
+rm -rf data/backup data/restore
 ./build/backer-cli backup data/source data/backup --pack tar --compress gzip
-
-# 指定压缩级别（1=最快, 9=最高压缩比）
-./build/backer-cli backup data/source data/backup --pack tar --compress lzma --compress-level 9
-
-# 还原：先解压 (gzip) 再解包 (tar)
+ls -lh data/backup.tar.gz
 ./build/backer-cli restore data/backup.tar.gz data/restore --pack tar --decompress gzip
- 
-# 三种算法均可
-./build/backer-cli backup data/source data/backup --pack tar --compress zstd
-./build/backer-cli backup data/source data/backup --pack tar --compress lzma
-```
-
-#### 文件命名
+ls -l data/restore
 
-备份时自动追加后缀（避免与用户已有的扩展名重复）：
+# zstd
+rm -rf data/backup data/restore
+./build/backer-cli backup data/source data/backup --pack tar --compress zstd
+ls -lh data/backup.tar.zst
+./build/backer-cli restore data/backup.tar.zst data/restore --pack tar --decompress zstd
+ls -l data/restore
 
+# lzma
+rm -rf data/backup data/restore
+./build/backer-cli backup data/source data/backup --pack tar --compress lzma
+ls -lh data/backup.tar.xz
+./build/backer-cli restore data/backup.tar.xz data/restore --pack tar --decompress lzma
+ls -l data/restore
 ```
---pack tar --compress gzip  → data/backup.tar.gz
---pack tar --compress zstd  → data/backup.tar.zst
---pack tar --compress lzma  → data/backup.tar.xz
-```
-
-还原时 `--decompress` 读取压缩归档，解压到临时文件后交给解包器，完成后自动清理临时文件。
 
-#### 算法选型建议
-
-| 场景 | 推荐 | 理由 |
+| 算法 | 后缀 | 特点 |
 |------|------|------|
-| 日常备份，追求速度 | `zstd` | 压缩/解压都极快，压缩比优秀 |
-| 通用兼容、跨工具交换 | `gzip` | 最广泛支持，与 `gunzip` 互通 |
-| 归档存储，最大化压缩 | `lzma` | 压缩比最高，但耗时与内存占用大 |
-
----
-
-### 加密解密
-
-备份归档（`.tar` / `.zip`）在可选的压缩步骤之后，可叠加加密以保护数据机密性。还原时先解密再解压（如有）最后解包。
-
-**命令形式**
-
-```text
-backup:   --encrypt <ALGO> [--password <PWD>]
-restore:  --decrypt <ALGO> [--password <PWD>]
-```
-
-**支持的算法**
-
-| 算法 | 选项值 | 密钥 | 模式 | 认证 | 密钥派生 |
-|------|--------|------|------|------|----------|
-| AES-256-GCM | `aes256` / `aes-256-gcm` | 256 位 | GCM（认证加密） | GCM 认证标签 (16B) | PBKDF2-SHA256 (100000 轮) |
-| SM4-CBC | `sm4` / `sm4-cbc` | 128 位 | CBC（密文分组链接） | — | PBKDF2-SM3 (100000 轮) |
-
-> OpenSSL 3.0 起支持 SM4。SM4-GCM 需要 OpenSSL ≥ 3.2，当前版本暂不提供。
-
-#### 密码提供方式
-
-密码可通过两种方式提供：
-
-**1. 命令行参数**（非交互式，适合脚本）：
-
-```bash
-./build/backer-cli backup data/source data/backup \
-    --pack tar --encrypt aes256 --password "your-passphrase"
-```
-
-**2. 交互式提示**（省略 `--password`，适合手动使用）：
-
-```bash
-./build/backer-cli backup data/source data/backup --pack tar --encrypt aes256
-Enter encryption password:        # 不回显输入
-Confirm encryption password:      # 确认（仅加密时）
-```
-
-> 交互模式下终端回显被关闭（`tcsetattr()`），密码不会显示在屏幕上。还原时只需输入一次密码。
-
-#### 示例
-
-```bash
-# 备份 → 打包 (tar) → 压缩 (gzip) → 加密 (AES-256-GCM)
-# 产出：data/backup.tar.gz.enc
-./build/backer-cli backup data/source data/backup --pack tar --compress gzip \
-    --encrypt aes256 --password "secret"
-
-# 仅加密（不压缩）
-# 产出：data/backup.tar.enc
-./build/backer-cli backup data/source data/backup --pack tar \
-    --encrypt aes256 --password "secret"
-
-# 使用 SM4-CBC 加密
-./build/backer-cli backup data/source data/backup --pack tar \
-    --encrypt sm4 --password "sm4-passphrase"
-
-# 还原：解密 → 解压 (gzip) → 解包 (tar)
-./build/backer-cli restore data/backup.tar.gz.enc data/restore \
-    --pack tar --decompress gzip --decrypt aes256 --password "secret"
-```
-
-#### 文件命名
-
-加密自动追加 `.enc` 后缀，与压缩后缀叠加：
-
-| 流水线 | 产出文件名 |
-|--------|-----------|
-| 仅加密 | `backup.tar.enc` |
-| 压缩 + 加密 | `backup.tar.gz.enc` |
-| 加密 + 压缩（暂不支持） | — |
-
-#### 安全特性
-
-| 特性 | 说明 |
-|------|------|
-| 随机 salt | 每次加密生成新的 16 字节 salt |
-| 随机 IV | 每次加密生成新的 12/16 字节 IV |
-| PBKDF2 迭代 | 100000 轮（可承受的抗暴力破解） |
-| GCM 认证标签 | AES 模式解密前验证，防止篡改 |
-| 内存清理 | 密钥使用后通过 `OPENSSL_cleanse` 清零 |
-| 日志安全 | 密码/密钥永不被日志记录 |
-| 错误密码检测 | 认证标签不通过不输出任何解密数据 |
+| gzip | `.gz` | 通用、解压快 |
+| zstd | `.zst` | 速度快、压缩比好 |
+| lzma | `.xz` | 压缩比最高 |

-### 定时备份（计划任务）
-
-用户通过 cron 表达式配置周期性备份任务，支持数据淘汰策略管理历史快照。
-
-**命令形式**
-
-```text
-backer schedule list                              # 列出所有任务
-backer schedule add <name> <cron> <source> <dest> [OPTIONS]   # 添加任务
-backer schedule remove <id>                       # 删除任务
-backer schedule enable <id>                       # 启用任务
-backer schedule disable <id>                      # 禁用任务
-```
-
-**相关选项（`schedule add`）**
-
-| 选项 | 说明 | 示例值 |
-|------|------|--------|
-| `--compress <ALGO>` | 压缩算法 | `gzip`, `zstd`, `lzma` |
-| `--compress-level <N>` | 压缩级别 | `1`–`9` |
-| `--encrypt <ALGO>` | 加密算法 | `aes256`, `sm4` |
-| `--password <PWD>` | 加密密码 | — |
-| `--pack <FMT>` | 打包格式 | `tar` |
-| `--retain-count <N>` | 保留最近 N 个快照 | `30` |
-| `--retain-days <N>` | 保留 N 天内的快照 | `7` |
-| `--no-metadata` | 不保留元数据 | — |
-| `--skip-special` | 跳过特殊文件 | — |
-
-**Cron 表达式支持格式**
-
-| 格式 | 类型 | 示例 |
-|------|------|------|
-| 标准 5 字段 | `分 时 日 月 周` | `0 2 * * *`（每天凌晨 2 点） |
-| 带秒 6 字段 | `秒 分 时 日 月 周` | `0 30 9 * * 1-5`（工作日 9:30） |
-| 步进 | `*/15 * * * *` | 每 15 分钟 |
-| 范围 | `0 9-18 * * *` | 每小时 0 分，9–18 点 |
-
-> 调度器自动检测表达式字段数（5 或 6），开发者无需关注格式差异。
-
-**示例**
+## 加密解密（每种10分，共20分）
 
 ```bash
-# 添加每日凌晨 2 点的备份任务，保留最近 30 个快照
-./build/backer-cli schedule add "每日备份" "0 2 * * *" /home/user/data /backup/daily \
-    --compress zstd --retain-count 30
-
-# 添加工作日 9 点的备份任务
-./build/backer-cli schedule add "工作日报备" "0 9 * * 1-5" /home/user/project /backup/project
-
-# 列出所有任务
-./build/backer-cli schedule list
-
-# 删除任务
-./build/backer-cli schedule remove job_每日备份
+# 备份 → 打包 → 压缩 → 加密
+rm -rf data/backup data/restore
+./build/backer-cli backup data/source data/backup --pack tar --compress gzip --encrypt aes256 --password "pwd"
+ls -lh data/backup.tar.gz.enc
+head -c 128 data/backup.tar.gz.enc | xxd  # 加密后文件无法直接读取
 
-# 禁用任务（暂不执行但不删除）
-./build/backer-cli schedule disable job_每日备份
+# 还原：解密 → 解压 → 解包
+./build/backer-cli restore data/backup.tar.gz.enc data/restore --pack tar --decompress gzip --decrypt aes256 --password "pwd"
+ls -l data/restore
 ```
 
-**数据淘汰策略**
-
-| 策略 | 选项 | 说明 |
+| 算法 | 选项 | 说明 |
 |------|------|------|
-| 按数量 | `--retain-count <N>` | 仅保留最近 N 个快照，超出则删除最旧的 |
-| 按时长 | `--retain-days <N>` | 删除 N 天之前的快照 |
-| 混合 | 两者同时使用 | 同时满足两个条件的快照才会被删除 |
-
-淘汰由 `backer daemon` 在执行备份后自动触发，扫描任务目标目录下命名格式为 `YYYYMMDD_HHMMSS` 的子目录进行清理。
+| AES-256-GCM | `aes256` | 认证加密，推荐 |
+| SM4-CBC | `sm4` | 国密算法 |
 
 ---
 
-### 守护进程模式
+## 定时备份（10分）
 
-`backer daemon` 启动后台调度循环，加载所有已配置的定时任务并按计划执行备份。
+支持 crontab 表达式设置周期性备份任务，可指定保留快照数量自动淘汰旧备份。
 
 ```bash
-# 启动守护进程（阻塞，按 Ctrl+C 停止）
-./build/backer-cli daemon
-```
-
-守护进程启动后：
-
-1. 加载 `~/.config/backer/schedule.json` 中的任务配置
-2. 计算每个启用的任务的下次触发时间
-3. 等待最近的任务触发
-4. 任务触发时：
-   - 在目标目录下创建带时间戳的快照子目录（`YYYYMMDD_HHMMSS`）
-   - 执行完整备份流程（含打包、压缩、加密等配置）
-   - 根据 `--retain-count` / `--retain-days` 淘汰过期快照
-5. 重新计算下次触发时间，进入等待循环
-6. 按 `Ctrl+C` 安全停止
-
-**持久化配置**
-
-任务配置存储在 `~/.config/backer/schedule.json`，手动编辑时注意保持 JSON 格式正确：
-
-```json
-{
-  "jobs": [
-    {
-      "id": "job_每日备份",
-      "name": "每日备份",
-      "cron": "0 2 * * *",
-      "source": "/home/user/data",
-      "destination": "/backup/daily",
-      "options": {
-        "compress": "zstd",
-        "retainCount": 30
-      },
-      "enabled": true,
-      "createdAt": "2026-07-12T10:00:00Z"
-    }
-  ]
-}
+./build/backer-cli schedule list                                    # 列出所有任务
+./build/backer-cli schedule add <name> <cron> <src> <dest> [OPTS]  # 添加任务
+./build/backer-cli schedule remove <id>                             # 删除任务
+./build/backer-cli schedule enable <id>                             # 启用任务
+./build/backer-cli schedule disable <id>                            # 禁用任务
 ```
 
-> 建议通过 `backer schedule` 命令管理任务而非直接编辑 JSON 文件。

Subject: [PATCH 33/36] fix(cli): replace POSIX strptime with standard
 std::get_time for cross-platform

strptime is a POSIX function unavailable on MSVC (Windows). Replace with
std::get_time (C++11, all platforms) + istringstream for identical parsing
behavior of YYYY-MM-DD[ HH:MM:SS] format.

 ## 📖 项目简介
 
-Backer 是计算机组成与体系结构/软件工程课程项目，基于 **C++17** 在 **Linux** 平台开发，使用 **CLI11** 提供命令行接口，**spdlog** 处理日志，**Google Test** 驱动测试。
+Backer 是一款 **Linux 平台的数据备份还原工具**，采用 **C++17** 开发，支持目录树备份与还原、特殊文件处理、元数据保留、灵活筛选、多格式打包、多算法压缩加密、图形界面与定时备份等完整功能。
 
-依赖通过 **CMake FetchContent** 自动拉取（CLI11 v2.4.2、spdlog v1.14.1、GTest v1.15.2），无需手动安装。加密功能依赖系统 OpenSSL（`libssl-dev`，通过 `find_package` 接入）。
+## 📁 项目结构
 
-**当前状态**：已完成核心备份/还原、特殊文件、元数据保留、自定义筛选（6 维度）、Tar/Zip 打包、gzip/zstd/lzma 压缩、AES-256-GCM/SM4-CBC 加密、Qt 6 图形界面及**定时备份（Cron 调度 + 数据淘汰）**。后续将通过管道架构扩展实时监控及网络备份等功能。

+要点：
+- 电子科技大学计算机专业最后一门实践必修课，综合运用本科所学知识
+- 围绕一个模拟实战软件项目，以 3 人团队完成从需求分析→系统设计→编码实现→集成测试的完整软件生命周期
+- 项目目标：开发一款**数据备份软件**，支持目录树的备份与还原，并可选实现多项扩展功能
+- 重点考察：正确性、易用性、健壮性
+---
+
+---
+标题：需求概述
+要点：
+- **基本要求**：目录树文件数据的备份与还原
+- **扩展要求**：
+  - 特殊文件支持（管道/链接/设备文件）
+  - 元数据支持（属主/时间/权限）
+  - 自定义筛选（路径/类型/名称/时间/尺寸/属主 6 维度）
+  - Tar / Zip 两种打包格式
+  - gzip / zstd / lzma 三种压缩算法
+  - AES-256-GCM / SM4-CBC 两种加密算法
+  - Qt 6 图形界面
+  - cron 定时备份与自动淘汰
+---
+
+---
+标题：总体架构设计
+要点：
+- 自底向上五层分层架构：(1)存储层（本地文件系统）→ (2)基础设施层（FSAbstraction/元数据管理/特殊文件支持）→ (3)管道层（Filter→Packer→Compressor→Encryptor）→ (4)业务层（BackupEngine/RestoreEngine/Scheduler）→ (5)表现层（CLI + GUI），各层间箭头标注数据流向。右侧标注关键技术：CLI11、spdlog、Qt6、OpenSSL、miniz、ccronexpr
+- 采用**五层分层架构** + **管道模式**设计
+  - 表现层：CLI (CLI11) + GUI (Qt 6)
+  - 业务层：BackupEngine / RestoreEngine / BackupScheduler
+  - 管道层：Filter → Packer → Compressor → Encryptor 可插拔组合
+  - 基础设施层：FSAbstraction / Metadata / 特殊文件处理
+  - 存储层：LocalStorage
+- 各层通过抽象接口通信，上层依赖下层，下层对上层无感知
+- ![五层分层架构](diagrams/dist/backer-layers.svg)
+---
+
+---
+标题：核心模块 — 备份/还原引擎
+要点：
+- **BackupEngine**: 备份流程编排器
+  - `walk(source)` → 遍历目录树获取 FileEntry 列表
+  - `filter(entries)` → 按 6 维度筛选
+  - `pack(entries)` → Tar/Zip 打包
+  - `compress(buffer)` → gzip/zstd/lzma 压缩
+  - `encrypt(buffer)` → AES/SM4 加密
+  - `storage.write()` → 持久化到本地
+- **RestoreEngine**: 还原流程编排器（逆操作）
+  - 支持目录镜像模式（逐个文件复制）和归档模式（打包文件）
+- 备份流程完整步骤：用户输入 backup 命令 → CLI 解析参数 → BackupEngine 调起 → FSAbstraction 遍历目录 → Filter 筛选 → Packer 打包 → Compressor 压缩 → Encryptor 加密 → Storage 写入磁盘，各步骤可选（虚线框标注）
+---
+
+---
+标题：核心模块 — 管道策略接口
+要点：
+- 采用**策略模式**设计管道阶段，新增算法无需修改现有代码
+- **Filter**：`apply(entries)` → 返回筛选后子集

+- ![UML 类图](diagrams/dist/backer-class.svg)
+---
+
+---
+标题：UML 建模 — 顺序图 / 构件图
+要点：
+- 一次完整备份请求的交互流程：用户→CLI→BackupEngine→FSAbstraction(walk)→Filter(apply)→Packer(pack)→Compressor(compress)→Encryptor(encrypt, PBKDF2+AES)→Storage(writeFile)→返回结果
+- 可执行构件（backer-cli/backer-gui/backer_test）与各编译单元（commands.cpp, backup_engine.cpp, tar_packer.cpp 等）及外部依赖（CLI11/spdlog/Qt6/OpenSSL/miniz/ccronexpr/Google Test）之间的链接和依赖关系

Subject: [PATCH 36/36] fix(ci): bundle VC++ runtime DLLs in Windows release
 package
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The Windows CLI binary (backer-cli.exe) dynamically links against the
MSVC runtime (/MD), but the release zip only contained OpenSSL DLLs
and Qt DLLs — the VC++ runtime DLLs (vcruntime140.dll, msvcp140.dll,
concrt140.dll, etc.) were missing. On machines without the Visual C++
Redistributable pre-installed, the executable fails to launch with a
"VCRUNTIME140.dll not found" error.

Add a packaging step that locates the VC++ CRT DLLs via vswhere from
Visual Studio redist directory and copies them into the release zip.
