+# PLONDS Comparator 改造设计
+
+> 日期：2026-05-30
+> 状态：待审批
+
+## 1. 背景与动机
+
+PLONDS（Penguin Logistics Online Network Distribution System）是 LanMountainDesktop 的文件驱动式分布式更新系统。当前 Comparator 工作流存在以下问题：
+
+1. **产出物过于复杂**：生成 `update-{platform}.zip`、`plonds-filemap-{platform}.json`、`plonds-filemap-{platform}.json.sig`、`platform-summary-{platform}.json`、`plonds-static.zip` 等多个文件，客户端消费困难
+2. **模型定义重复**：`Plonds.Shared`、`Plonds.Core`、宿主侧、Launcher 侧各自定义独立的 DTO，字段名不一致
+3. **签名机制过重**：RSA 签名增加了 CI 复杂度（需要管理密钥），且对文件驱动式更新系统而言 SHA256 哈希校验已足够
+4. **平台覆盖不当**：Linux 平台不需要 PLONDS 支持，macOS 尚未接入，但代码中硬编码了三个平台
+5. **工作流间 artifact 传递脆弱**：Comparator → Publisher 通过 artifact 传递 `plonds-static.zip`，容易断裂
+
+## 2. 设计目标
+
+- 产出物精简为两个文件：`changed.zip` + `PLONDS.json`
+- 去掉 RSA 签名，只用 SHA256/MD5 校验
+- 只关注 Windows 平台
+- 统一模型定义，消除 DTO 重复
+- 保持 Comparator 和 Publisher 两个工作流的职责分离
+
+## 3. 新产出物定义
+
+### 3.1 changed.zip
+
+只包含与上一版本有差异的文件（action 为 `add` 或 `replace` 的文件），目录结构与部署目录一致。
+
+### 3.2 PLONDS.json
+
+```json
+{
+  "formatVersion": "2.0",
+  "currentVersion": "1.2.0",
+  "previousVersion": "1.1.0",
+  "isFullUpdate": false,
+  "requiresCleanInstall": false,
+  "channel": "stable",
+  "platform": "windows-x64",
+  "updatedAt": "2026-05-30T12:00:00Z",
+
+  "filesMap": {
+    "LanMountainDesktop.exe": {
+      "action": "replace",
+      "sha256": "abc123...",
+      "size": 1024000
+    },
+    "LanMountainDesktop.dll": {
+      "action": "reuse",
+      "sha256": "def456...",
+      "size": 512000
+    },
+    "OldModule.dll": {
+      "action": "delete",
+      "sha256": "",
+      "size": 0
+    }
+  },
+
+  "changedFilesMap": {
+    "LanMountainDesktop.exe": {
+      "archivePath": "LanMountainDesktop.exe",
+      "sha256": "abc123...",
+      "size": 1024000
+    }
+  },
+
+  "checksums": {
+    "changed.zip": "md5:9a8b7c6d..."
+  }
+}
+```
+
+### 3.3 字段语义
+
+| 字段 | 类型 | 说明 |
+|------|------|------|
+| `formatVersion` | string | 协议版本，固定 `"2.0"` |
+| `currentVersion` | string | 当前发布版本 |
+| `previousVersion` | string | 基线版本（全量更新时为 `"0.0.0"`） |
+| `isFullUpdate` | bool | 是否为全量更新（找不到基线版本时为 true） |
+| `requiresCleanInstall` | bool | 启动器是否也更新了——如果是，客户端不走增量流程，让用户重新运行安装器 |
+| `channel` | string | 更新通道：`stable` 或 `preview` |
+| `platform` | string | 平台标识：`windows-x64` |
+| `updatedAt` | string | ISO 8601 时间戳 |
+| `filesMap` | object | 全量文件图：每个文件的 action + sha256 + size |
+| `changedFilesMap` | object | 变更文件图：只包含需要从 changed.zip 解压的文件 |
+| `checksums` | object | 产出物的 MD5 值 |
+
+### 3.4 filesMap 中 action 的值
+
+| Action | 含义 | changed.zip 中是否包含 |
+|--------|------|----------------------|
+| `add` | 新增文件 | ✅ |
+| `replace` | 替换文件 | ✅ |
+| `reuse` | 复用上一版本文件 | ❌ |
+| `delete` | 删除文件 | ❌ |
+
+### 3.5 requiresCleanInstall 判断逻辑
+
+比较 `LanMountainDesktop.Launcher.exe` 在当前版本和基线版本中的 SHA256：
+- 如果 SHA256 不同 → `requiresCleanInstall = true`
+- 如果 SHA256 相同或没有基线版本 → `requiresCleanInstall = false`
+
+## 4. Plonds.Tool build-delta 命令改造
+
+### 4.1 新命令签名
+
+```
+build-delta --platform <platform>
+            --current-version <version>
+            --current-zip <file>
+            --output-dir <dir>
+            --channel <channel>
+            [--baseline-version <version>]
+            [--baseline-zip <file>]
+            [--launcher-path <relative-path>]
+```
+
+### 4.2 参数说明
+
+| 参数 | 必需 | 说明 |
+|------|------|------|
+| `--platform` | 是 | 平台标识，如 `windows-x64` |
+| `--current-version` | 是 | 当前发布版本号 |
+| `--current-zip` | 是 | 当前版本的 payload zip 路径 |
+| `--output-dir` | 是 | 输出目录 |
+| `--channel` | 是 | 更新通道 |
+| `--baseline-version` | 否 | 基线版本号（省略则视为全量更新） |
+| `--baseline-zip` | 否 | 基线版本的 payload zip 路径（省略则视为全量更新） |
+| `--launcher-path` | 否 | Launcher 可执行文件的相对路径，默认 `LanMountainDesktop.Launcher.exe` |
+
+### 4.3 删除的参数
+
+| 参数 | 原因 |
+|------|------|
+| `--current-tag` | 不再需要，version 就够了 |
+| `--private-key` | 去掉签名 |
+| `--is-full-payload` | 自动判断：没有 baseline-zip 就是全量 |
+| `--static-output-dir` | 不再生成 S3 静态布局 |
+| `--update-base-url` | 不再生成 S3 URL |
+| `--baseline-tag` | 不再需要 |
+
+### 4.4 内部逻辑
+
+```
+1. 解压 current-zip → currentDir
+2. 如果有 baseline-zip → 解压 → baselineDir
+   否则 → baselineDir = 空（全量更新）
+
+3. 扫描 currentDir → 计算 SHA256
+4. 扫描 baselineDir → 计算 SHA256（如果有）
+
+5. 对比生成 filesMap:
+   - 两个版本都有且 SHA256 相同 → reuse
+   - 两个版本都有但 SHA256 不同 → replace
+   - 只在新版本中存在 → add
+   - 只在旧版本中存在 → delete
+
+6. 从 filesMap 提取 changedFilesMap:
+   - 只包含 action=add/replace 的条目
+   - 添加 archivePath（在 changed.zip 中的路径）
+
+7. 打包 changed.zip:
+   - 只包含 add/replace 的文件
+   - 保持原始目录结构
+
+8. 判断 requiresCleanInstall:
+   - 比较 Launcher 可执行文件在两个版本中的 SHA256
+   - 如果不同 → requiresCleanInstall=true
+
+9. 计算 changed.zip 的 MD5
+
+10. 生成 PLONDS.json
+
+11. 输出到 output-dir:
+    - changed.zip
+    - PLONDS.json
+```
+
+### 4.5 不再生成的产物
+
+| 旧产物 | 处置 |
+|--------|------|
+| `update-{platform}.zip` | 被 `changed.zip` 替代 |
+| `plonds-filemap-{platform}.json` | 被 `PLONDS.json` 替代 |
+| `plonds-filemap-{platform}.json.sig` | 去掉签名 |
+| `platform-summary-{platform}.json` | 不再需要 |
+| `plonds-static.zip` | 不再生成 S3 静态布局 |
+| `meta/channels/...` | 不再由 Tool 生成，由 Publisher 负责 |
+
+## 5. Plonds.Shared 模型改造
+
+### 5.1 删除的模型
+
+| 模型 | 原因 |
+|------|------|
+| `PlondsFileMap` | 被新的 `PlondsManifest` 替代 |
+| `PlondsFileEntry` | 被新的 `PlondsFileEntry` 替代 |
+| `PlondsComponent` | 不再有组件概念 |
+| `PlondsDistributionInfo` | 不再生成分发文档 |
+| `PlondsChannelPointer` | 由 Publisher 用脚本生成 |
+| `PlondsReleaseManifest` | 不再需要 |
+| `PlondsReleasePlatformEntry` | 不再需要 |
+| `PlondsSignatureDescriptor` | 去掉签名 |
+| `PlondsMirrorAsset` | 由 Publisher 处理 |
+| `PlondsMirrorEntry` | 由 Publisher 处理 |
+| `PlondsMetadataCatalog` | 不再需要 |
+| `PlondsAssetEntry` | 不再需要 |
+
+### 5.2 新模型定义
+
+```csharp
+// PlondsManifest — 对应 PLONDS.json
+public sealed record PlondsManifest(
+    string FormatVersion,
+    string CurrentVersion,
+    string PreviousVersion,
+    bool IsFullUpdate,
+    bool RequiresCleanInstall,
+    string Channel,
+    string Platform,
+    DateTimeOffset UpdatedAt,
+    IReadOnlyDictionary<string, PlondsFileEntry> FilesMap,
+    IReadOnlyDictionary<string, PlondsChangedFileEntry> ChangedFilesMap,
+    IReadOnlyDictionary<string, string> Checksums);
+
+// PlondsFileEntry — filesMap 中的条目
+public sealed record PlondsFileEntry(
+    string Action,       // add | replace | reuse | delete
+    string Sha256,
+    long Size);
+
+// PlondsChangedFileEntry — changedFilesMap 中的条目
+public sealed record PlondsChangedFileEntry(
+    string ArchivePath,  // 在 changed.zip 中的路径
+    string Sha256,
+    long Size);
+```
+
+### 5.3 设计决策
+
+- `FilesMap` 和 `ChangedFilesMap` 用 `IReadOnlyDictionary<string, T>` 而非 `IReadOnlyList<T>`，key 就是文件相对路径，查找 O(1)
+- 去掉 `Component` 概念——当前只有一个 `app` 组件，分层没有实际意义
+- `FormatVersion` 固定为 `"2.0"`，与旧格式区分
+
+## 6. Comparator 工作流改造
+
+### 6.1 保留两个工作流
+
+- **Comparator**（`plonds-comparator.yml`）：比较文件生成器，只负责生成 `changed.zip` + `PLONDS.json`
+- **Publisher**（`plonds-publisher.yml`，原 `plonds-uploader.yml`）：发布器，负责上传到 S3 和生成 channel pointer
+
+### 6.2 Comparator 改造后步骤
+
+```yaml
+# plonds-comparator.yml
+触发: release.published / release.prereleased / workflow_dispatch
+
+jobs:
+  compare:
+    runs-on: ubuntu-latest
+    steps:
+      - Checkout
+
+      - 解析发布上下文
+        → RELEASE_TAG, RELEASE_VERSION, RELEASE_CHANNEL
+
+      - Setup .NET
+
+      - 构建 PLONDS Tool
+
+      - 解析基线版本
+        → 查找上一个同频道 Release
+        → 如果有 → 记录 baseline_tag, baseline_version
+        → 如果没有 → is_full_update=true
+
+      - 下载 payload zips
+        → 下载当前版本 files-windows-x64.zip
+        → 下载基线版本 files-windows-x64.zip (如果有)
+
+      - 运行 build-delta
+        → dotnet run Plonds.Tool -- build-delta \
+            --platform windows-x64 \
+            --current-version $VERSION \
+            --current-zip files-windows-x64.zip \
+            --output-dir plonds-output \
+            --channel $CHANNEL \
+            [--baseline-version $BASELINE_VERSION] \
+            [--baseline-zip baseline-files-windows-x64.zip]
+
+      - 上传到 GitHub Release
+        → gh release upload changed.zip PLONDS.json
+
+      - 传递元数据给 Publisher
+        → 上传 artifact: plonds-run-metadata (tag.txt)
+```
+
+### 6.3 与当前步骤的差异
+
+| 当前步骤 | 改造后 |
+|---------|--------|
+| 准备签名密钥 | ❌ 删除 |
+| 解析基线计划 (pwsh，三平台) | ✅ 简化：只找 Windows，逻辑简化 |
+| 下载 payload zips (pwsh，三平台) | ✅ 简化：只下载 Windows |
+| 构建增量资产 (pwsh，含 build-index + 静态布局验证 + plonds-static.zip 打包) | ✅ 简化：只调用 build-delta |
+| 上传 PLONDS assets 到 release | ✅ 简化：只上传 changed.zip + PLONDS.json |
+| 传递元数据 | ✅ 保留，但 artifact 内容简化 |
+
+## 7. 双模式差分生成
+
+### 7.1 概述
+
+Comparator 支持两种差分生成方法，通过 `workflow_dispatch` 的 `compare_method` 输入项选择：
+
+| 方法 | 标识 | 核心思路 |
+|------|------|---------|
+| 方法一 | `file-compare` | 下载两个版本的 files zip，全量文件哈希对比 |
+| 方法二 | `commit-analyze` | 分析两个版本之间的 git commit，映射源码变更到产物文件 |
+
+### 7.2 GitHub Actions 触发器新增输入项
+
+```yaml
+workflow_dispatch:
+  inputs:
+    tag: ...
+    baseline_tag: ...
+    channel: ...
+    compare_method:          # 新增
+      description: '比较方法'
+      type: choice
+      default: file-compare
+      options:
+        - file-compare
+        - commit-analyze
+    hash_algorithm:          # 新增（仅方法一）
+      description: '哈希算法'
+      type: choice
+      default: sha256
+      options:
+        - sha256
+        - md5
+```
+
+当由 `release` 事件触发时，默认使用 `file-compare` + `sha256`。
+
+### 7.3 方法一：文件对比模式（file-compare）
+
+**流程：**
+
+```
+1. 下载当前版本 files-windows-x64.zip
+2. 下载基线版本 files-windows-x64.zip（如果有）
+3. 解压两个 zip 到临时目录
+4. 用指定哈希算法（sha256/md5）扫描两个目录的所有文件
+5. 对比哈希值，生成 filesMap（add/replace/reuse/delete）
+6. 从当前版本目录中提取 add/replace 的文件 → changed.zip
+7. 生成 PLONDS.json
+```
+
+**PlondsDeltaBuildOptions 新增参数：**
+
+```csharp
+string HashAlgorithm = "sha256"  // "sha256" | "md5"
+```
+
+**哈希算法对 PLONDS.json 的影响：**
+
+- `sha256`：`filesMap` 和 `changedFilesMap` 中使用 `sha256` 字段
+- `md5`：`filesMap` 和 `changedFilesMap` 中使用 `md5` 字段
+
+### 7.4 方法二：Commit 分析模式（commit-analyze）
+
+**流程：**
+
+```
+1. 下载当前版本 files-windows-x64.zip
+2. 解压到临时目录
+3. git log --name-only baseline_tag..current_tag
+   → 得到两个版本之间的 commit 列表和涉及的源码文件
+4. 过滤：只保留源码目录下的文件
+5. 用简单规则映射源码文件到产物文件
+6. 从当前版本的解压目录中提取映射到的产物文件 → changed.zip
+7. 生成 PLONDS.json
+8. 如果没有源码变更 → 自动回退到方法一
+```
+
+**源码目录过滤规则：**
+
+只分析以下目录下的文件变更：
+
+| 目录 | 说明 |
+|------|------|
+| `LanMountainDesktop/` | 主宿主应用 |
+| `LanMountainDesktop.Launcher/` | 启动器 |
+| `LanMountainDesktop.Shared.Contracts/` | 共享契约 |
+| `LanMountainDesktop.PluginSdk/` | 插件 SDK |
+| `LanMountainDesktop.Appearance/` | 外观系统 |
+| `LanMountainDesktop.Settings.Core/` | 设置核心 |
+| `LanMountainDesktop.ComponentSystem/` | 组件系统 |
+
+忽略的目录：`docs/`、`scripts/`、`.github/`、`.trae/`、`PenguinLogisticsOnlineNetworkDistributionSystem/`
+
+**源码到产物的映射规则：**
+
+| 源码路径模式 | 映射到产物文件 |
+|-------------|--------------|
+| `LanMountainDesktop/**/*.{cs,axaml,xaml}` | `LanMountainDesktop.dll`, `LanMountainDesktop.exe` |
+| `LanMountainDesktop.Launcher/**/*.{cs,axaml,xaml}` | `LanMountainDesktop.Launcher.exe` |
+| `LanMountainDesktop.Shared.Contracts/**/*.cs` | `LanMountainDesktop.Shared.Contracts.dll` |
+| `LanMountainDesktop.PluginSdk/**/*.cs` | `LanMountainDesktop.PluginSdk.dll` |
+| `LanMountainDesktop.Appearance/**/*.cs` | `LanMountainDesktop.Appearance.dll` |
+| `LanMountainDesktop.Settings.Core/**/*.cs` | `LanMountainDesktop.Settings.Core.dll` |
+| `LanMountainDesktop.ComponentSystem/**/*.cs` | `LanMountainDesktop.ComponentSystem.dll` |
+| `**/*.json`（配置文件） | 同路径的 .json |
+| 其他无法映射的变更 | 保守标记 → 所有核心 .dll/.exe |
+
+**方法二在 Plonds.Tool 中的新命令：**
+
+```
+build-delta-from-commits --platform <platform>
+                         --current-version <version>
+                         --current-zip <file>
+                         --output-dir <dir>
+                         --channel <channel>
+                         --baseline-tag <tag>
+                         --current-tag <tag>
+                         [--source-dirs <dir1,dir2,...>]
+                         [--fallback-zip <file>]
+```
+
+| 参数 | 必需 | 说明 |
+|------|------|------|
+| `--platform` | 是 | 平台标识 |
+| `--current-version` | 是 | 当前发布版本号 |
+| `--current-zip` | 是 | 当前版本的 payload zip |
+| `--output-dir` | 是 | 输出目录 |
+| `--channel` | 是 | 更新通道 |
+| `--baseline-tag` | 是 | 基线版本的 git tag |
+| `--current-tag` | 是 | 当前版本的 git tag |
+| `--source-dirs` | 否 | 要分析的源码目录列表（逗号分隔） |
+| `--fallback-zip` | 否 | 回退到方法一时使用的基线 zip |
+
+**回退逻辑：**
+
+如果 `git log` 分析后发现没有源码目录下的文件变更（比如只有 docs/ 变更），则自动回退到方法一：
+1. 如果提供了 `--fallback-zip` → 用方法一对比两个 zip
+2. 如果没有提供 → 生成全量更新（`isFullUpdate=true`）
+
+### 7.5 方法二的 PLONDS.json 特殊处理
+
+方法二无法像方法一那样生成完整的 `filesMap`（因为不知道哪些文件是 reuse 的），因此：
+
+- `filesMap` 只包含映射到的变更文件（标记为 `add` 或 `replace`）
+- 不包含 `reuse` 和 `delete` 条目
+- `isFullUpdate` 始终为 `false`（除非回退到方法一且无基线）
+- `requiresCleanInstall` 根据 Launcher.exe 是否在映射到的变更文件列表中判断
+
+### 7.6 工作流中的条件分支
+
+```yaml
+- name: Run build-delta
+  shell: bash
+  run: |
+    if [[ "$COMPARE_METHOD" == "commit-analyze" ]]; then
+      # 方法二
+      dotnet run --project ... -- build-delta-from-commits \
+        --platform windows-x64 \
+        --current-version $RELEASE_VERSION \
+        --current-zip $PWD/plonds-input/current-files-windows-x64.zip \
+        --output-dir $PWD/plonds-output \
+        --channel $RELEASE_CHANNEL \
+        --baseline-tag $BASELINE_TAG \
+        --current-tag $RELEASE_TAG \
+        --fallback-zip $PWD/plonds-input/baseline-files-windows-x64.zip
+    else
+      # 方法一
+      dotnet run --project ... -- build-delta \
+        --platform windows-x64 \
+        --current-version $RELEASE_VERSION \
+        --current-zip $PWD/plonds-input/current-files-windows-x64.zip \
+        --output-dir $PWD/plonds-output \
+        --channel $RELEASE_CHANNEL \
+        --hash-algorithm $HASH_ALGORITHM \
+        --baseline-version $BASELINE_VERSION \
+        --baseline-zip $PWD/plonds-input/baseline-files-windows-x64.zip
+    fi
+```
+
+方法二时，基线 zip 仍然需要下载（用于回退），但不需要解压（除非回退）。
+
+### 7.7 两种方法的步骤差异
+
+| 步骤 | 方法一 (file-compare) | 方法二 (commit-analyze) |
+|------|----------------------|------------------------|
+| 下载基线 zip | ✅ 需要 | ✅ 需要（用于回退） |
+| 下载当前 zip | ✅ | ✅ |
+| 解压两个 zip | ✅ | ✅ 只解压当前（回退时解压基线） |
+| git diff/log | ❌ | ✅ 需要 fetch-depth:0 |
+| 哈希对比 | ✅ 两个目录全量扫描 | ❌ 不做（除非回退） |
+| 源码→产物映射 | ❌ | ✅ |
+| 回退逻辑 | ❌ | ✅ 无源码变更时回退方法一 |
+

+- **删除字体说明文档**：移除了 MiSans-NOTICE.md
+- **潜在目的**：减小应用体积，可能改用系统字体或其他字体方案
+
+#### 2. PLONDS 系统改进
+- **工作流更新**：`.github/workflows/plonds-comparator.yml` 有 138 行新增，157 行删除
+  - 移除了 `edited` 事件类型触发
+  - 工作流名称保持不变
+- **新增规格文档**：`.trae/specs/plonds-comparator-redesign/spec.md` 有 512 行新内容，描述了 PLONDS 比较器的重设计
+
+#### 3. 桌面组件系统调整
+- **FusedDesktopManagerService.cs**：106 行新增，41 行删除
+- **DesktopWidgetWindow.axaml.cs**：135 行新增，1 行删除
+- **FusedDesktopComponentLibraryWindow.axaml.cs**：23 行变更
+- **App.axaml.cs**：19 行新增，117 行删除（大幅精简）
+
+#### 4. 新增 CheckIpcAot 项目
+- 新增独立的项目 `CheckIpcAot`，包含项目文件和简单的 Program.cs
+- 可能用于测试 IPC 的 AOT 兼容性
+
+#### 5. Launcher 相关调整
+- `AppJsonContext.cs` 新增 5 行
+- AOT 配置文件有小幅变更
+
+#### 6. 测试清理
+- 删除了 `WindowLayerIsolationTests.cs` 中的 5 行测试代码
+
+## 代码审查要点
+
+### 优势
+1. **体积优化**：删除大量字体文件可显著减小应用体积
+2. **PLONDS 改进**：工作流优化和重设计规格表明对发布流程有改进
+3. **代码精简**：App.axaml.cs 的大幅精简符合代码整洁原则
+4. **文档完善**：新增 PLONDS 重设计规格文档，便于理解和维护
+
+### 潜在风险
+1. **字体缺失**：删除所有 MiSans 字体文件可能导致应用显示问题，需确保已提供替代方案
+2. **测试覆盖减少**：删除了窗口层隔离测试代码，需确认是否有替代测试
+3. **工作流变更**：PLONDS 工作流的修改需要验证发布流程是否仍然正常工作
+4. **兼容性**：CheckIpcAot 项目的添加可能引入新的依赖或 AOT 相关问题
+
+### 建议
+1. **验证字体替代方案**：确认应用是否已配置使用系统字体或其他字体
+2. **测试 PLONDS 工作流**：手动触发一次工作流验证其正常运行
+3. **补充测试**：如果删除的测试是重要的，考虑补充替代测试
+4. **验证桌面组件功能**：重点测试桌面组件窗口和管理器的变更是否正常工作
+5. **检查 AOT 配置**：确保新增的 CheckIpcAot 项目和 Launcher AOT 变更不会影响现有 AOT 构建
