 ## TraceMemo（迹忆）是什么
-TraceMemo（迹忆）是一款本地优先、可追溯的 AI 微信知识与分析工作台。
+TraceMemo（迹忆）是一款**本地优先、可追溯的 AI 微信知识与分析工作台**。
-TraceMemo（迹忆）原名 WechatExplorer，是一次从“微信聊天记录探索工具”向“可追溯的本地 AI 知识工作台”演进后的正式品牌升级。
+TraceMemo 原名 **WechatExplorer**，是一次从“微信聊天记录探索工具”向“可追溯的本地 AI 知识工作台”演进后的正式品牌升级。
 ## 为什么叫 TraceMemo（迹忆）
 `Trace` 代表聊天记录留下的痕迹、可以追溯的信息来源、AI 搜索过程，以及从结果回到原始聊天上下文并核对证据的能力。
 `Memo` 代表记忆、知识沉淀和长期保存：让聊天中产生的信息逐渐形成个人知识。
 “迹忆”可以理解为“留下痕迹的记忆”。TraceMemo 不是单纯查看微信聊天记录的工具，而是希望让聊天中产生的信息留下痕迹，并能够被再次找到、理解、验证和沉淀。
 > **品牌说明**
 >
 > TraceMemo（迹忆）原名 WechatExplorer。WechatExplorer 最初是一个用于查看和探索微信聊天记录的工具。随着本地搜索、AI 问答、来源追溯、知识库、日报、语音转写和 Agent 能力逐渐形成，项目已经从单纯的聊天记录查看器发展为本地 AI 知识与分析工作台，因此在 v2.2.0 正式更名为 TraceMemo（迹忆）。
 它可以帮你浏览、搜索和整理微信历史，也可以让 AI 帮你找回聊过的内容，并回到原始消息核对答案。
 你可以直接浏览聊天，也可以用自然语言提问：
 > “上个月我们讨论过哪些发布问题？”
 >
 > “张三之前发过的项目地址在哪里？”
 >
 > “技术交流群今天有哪些结论和待办？”
-它和普通聊天记录查看器最大的不同，是 AI 不只是告诉你答案，还会告诉你答案来自哪里。你可以看到答案参考了哪些内容、来自哪个会话和时间，再回到原始消息确认它有没有理解错。
+它和普通聊天记录查看器最大的不同，是 AI 不只是告诉你答案，还会告诉你答案来自哪里。
 你可以看到答案参考了哪些内容、来自哪个会话和时间，再回到原始消息确认它有没有理解错。
 TraceMemo 不提供任何微信聊天数据，也不鼓励收集、上传、出售、共享或未经授权处理他人的聊天记录。使用 TraceMemo 时，请确保你对所处理的数据具有合法的访问和使用权限，并自行承担相应的数据安全与合规责任。

 ## 项目缘起
 <details>
 TraceMemo 最早叫 **WechatExplorer**。
 **2025 年 12 月**，我做出了第一个版本。当时功能很简单：解析微信 3.0 的聊天记录，再用 AI 生成群聊日报。最初只是给自己用，想把散落在微信里的信息重新找出来，也方便看看群里每天聊了什么。
 第一个版本完成后，项目搁置了一段时间。后来重新捡起来，我还是想继续做群聊日报，但微信已经更新到 4.x，原来的微信 3.0 数据解析方案不再适用。
 为了支持微信 4.x，我开始重新研究数据访问。这部分工作得到了 **WeFlow** 很大的帮助。TraceMemo 目前的微信 4.x 数据连接能力，参考并使用了 **WeFlow 历史版本中的相关实现和思路**，包括数据库密钥获取、图片解密等底层能力。
 > **没有 WeFlow，就没有今天的 TraceMemo。**
 WeFlow 帮我跨过了微信 4.x 数据访问这道门槛，我才有机会继续做后面的事情：让聊天记录可以被搜索、理解和总结，也让 AI 给出的答案能够回到原始消息核对。
 在此基础上，项目陆续加入了：
 - 本地知识库
 - 消息来源追溯
 - 群聊日报
 - 语音消息也参与知识库等问答
 - 微信机器人
 - Local HTTP API
 - Reader Skill
 - Agent 接入
 - 多种聊天记录导出能力
 群聊日报后来被一些人看到，项目也开始有了 Star、Fork、使用反馈和功能建议。说实话，我一开始没想到，这个原本只给自己用的小工具，会得到这么多人的关注。
 这些关注和反馈让我决定认真把项目继续做下去。WechatExplorer 就这样一步一步变成了今天的 **TraceMemo（迹忆）**。
 感谢 WeFlow，也感谢每一位使用、关注和反馈过 TraceMemo 的人。

-</details>
+这个项目起初只是一个一时兴起的项目，所以它大概也不会有一份特别严肃的产品路线图。
 我可能会按照自己的兴趣继续折腾，也可能突然加入一些奇奇怪怪、但觉得有意思的功能—— 比如让AI给某个好友, 某个群发一个语音条(逗逗群友) 或者定时生成群聊日报并做成微信卡片。
 也因此，这个项目随时可能继续折腾，也可能因为其他事情暂时搁置。如果你有想要的功能，可以提Issue；如果觉得现有实现不符合你的需求，也欢迎直接 Fork 后自己改。

 # 实验性功能：自托管微信分享卡片
 ![微信卡片分享效果示例](../../public/微信卡片分享.png)
 > **实验性功能**  
 > 该能力需要用户自行准备 Cloudflare、域名和微信公众平台测试号，目前不属于开箱即用的稳定功能。Cloudflare、微信 JS-SDK、测试号权限或微信客户端行为变化，都可能导致分享卡片失效。
 ## 新手推荐：直接交给 Agent
 如果你不熟悉 Cloudflare、Wrangler 或命令行，不需要手动照着整篇文档操作。把下面这个 Skill 文件夹交给 Codex、Claude Code 或其他能够操作项目终端的编程 Agent：
 ```text
 docs/skill/setup-wechat-share-card/
 ```
 然后对 Agent 说：
 ```text
 请使用 setup-wechat-share-card Skill，帮我部署 TraceMemo 的实验性微信分享卡片服务。尽量自动完成，只在缺少必要信息时一次性问我。
 ```
 Agent 会自动：
 - 检查 Node.js、pnpm 和 Wrangler；
 - 必要时临时下载 Wrangler；
 - 打开 Cloudflare 登录并执行 `whoami`；
 - 自动生成 `UPLOAD_TOKEN`；
 - 创建或复用私有 R2 Bucket；
 - 写入 Worker Secret；
 - 根据你的域名生成本机 Worker 配置；
 - 部署 Worker并执行健康检查和微信签名检查；
 - 把上传密钥复制到剪贴板，供你粘贴到 TraceMemo。
 Agent 无法替你创建微信测试号或决定使用哪个域名，因此通常只需要你提供：
 1. 你准备使用的分享域名，例如 `share.example.com`；
 2. 微信测试号页面中的 AppID；
 3. 微信测试号页面中的 AppSecret；
 4. 浏览器弹出 Cloudflare OAuth 页面时完成一次登录授权。
 真实配置保存在被 Git 忽略的本机 `.env` 中，不会写入 `.env.example`。不要把 `.env` 发给别人或提交到仓库。
 TraceMemo 可以把已经生成的群聊日报长图发布为一个临时网页，并在微信中分享成带有标题、描述和缩略图的卡片。
 TraceMemo **不提供公共卡片服务器**。使用该功能前，需要按照本文部署一套属于你自己的卡片服务。日报图片将上传到你自己的 Cloudflare R2，而不是上传到 TraceMemo 作者的服务器。
 ## 这个功能解决什么问题
 直接把日报 PNG 发到微信，只会显示为一张普通图片。微信卡片还需要：
 - 一个域名 (未能备案的话 在微信里点击多次 可能会被微信内置窗口提示需要备案)；
 - 卡片标题和描述；
 - 一张微信可以读取的缩略图；
 - 微信 JS-SDK 签名；
 - 一个临时保存日报图片的位置。
 本项目提供的 Cloudflare Worker 负责这些工作。桌面端上传日报后，会得到一个分享链接和二维码。用微信扫码打开链接，再点击右上角菜单分享，即可生成微信卡片。
 ## 数据会经过哪里
 ```mermaid

 ```
 与 TraceMemo 的本地浏览能力不同，启用分享卡片后，当前日报长图、缩略图、卡片标题和描述会离开本机，上传到你控制的 Cloudflare 账号。

 ## 理解三个重要配置
 ### `UPLOAD_TOKEN` 从哪里来
 `UPLOAD_TOKEN` **不是从 Cloudflare 或微信后台领取的**，它是卡片服务部署者自己生成的一段随机密码。
 它用于保护 Worker 的上传接口：TraceMemo 上传日报时，会发送：
 ```http
 Authorization: Bearer <UPLOAD_TOKEN>
 ```
 Worker 只有在密钥完全一致时才接受上传。没有它，任何知道接口地址的人都可能向你的 R2 上传文件并消耗资源。
 在 macOS 或 Linux 中生成一枚 64 位十六进制随机密钥：
 ```bash
 openssl rand -hex 32
 ```
 示例输出只用于说明格式，不要直接使用：
 ```text
 8a4d...一共 64 个十六进制字符...72ef
 ```
 生成后，同一个值需要配置到两个地方：
 1. Cloudflare Worker Secret `UPLOAD_TOKEN`；
 2. TraceMemo“生成微信卡片”弹窗中的“上传密钥”。
 如果两边不一致，卡片服务会返回 HTTP 401 或“未授权”。
 TraceMemo 会使用 Electron `safeStorage` 将服务地址和上传密钥加密保存在本机。不要把密钥提交到 Git，也不要写入 `wrangler.jsonc`。
 ### AppID 和 AppSecret 从哪里来
 打开[微信公众平台接口测试号](https://mp.weixin.qq.com/debug/cgi-bin/sandboxinfo?action=showinfo&t=sandbox/index)，使用微信扫码登录。
 页面上方会显示：
 - `appID`；
 - `appsecret`。
 将它们分别保存为 Worker Secret：
 ```text
 WECHAT_APP_ID
 WECHAT_APP_SECRET
 ```
 它们的作用不同：
 - AppID 用于标识这个微信测试应用；
 - AppSecret 是高敏感凭据，Worker 用它向微信服务器获取 `access_token`；
 - Worker 再使用 `access_token` 获取 `jsapi_ticket`；
 - 最后使用 `jsapi_ticket`、当前网页 URL、时间戳和随机串生成 JS-SDK 签名。
 AppSecret 只能保存在 Worker Secret 中。不要把它填写到 TraceMemo 的“上传密钥”输入框，不要发送给前端，也不要提交到仓库。怀疑泄露时，应立即在微信后台重置并更新 Worker Secret。
 ### JS 接口安全域名是干什么的
 JS 接口安全域名是微信对网页来源的白名单。
 假设你的分享服务地址是：
 ```text
 https://share.example.com
 ```
 那么测试号页面中的“JS 接口安全域名”应填写：
 ```text
 share.example.com
 ```
 填写时：
 - 不带 `https://`；
 - 不带 `/s/xxx` 等路径；
 - 不要填写 Cloudflare Worker 名称；
 - 必须与用户实际打开分享页时的域名一致。
 它不是用来解析 DNS 的。域名仍然需要先在 Cloudflare 中正确绑定到 Worker。安全域名的作用是告诉微信：允许这个域名下的网页使用当前 AppID 请求 JS-SDK 能力。
 如果没有配置、填错域名，或签名 URL 与实际页面 URL 不一致，通常会出现 `invalid signature`、`config:fail` 或分享信息没有生效。
 微信可能要求下载一个 TXT 验证文件，并确保它可以通过下面的地址访问：
 ```text
 https://share.example.com/微信提供的文件名.txt
 ```
 项目 Worker 已包含根路径验证文件的实现方式。你需要把自己的文件名和内容加入 `services/share-card-worker/src/index.js` 中的 `WECHAT_DOMAIN_VERIFICATION`，然后重新部署。
 ## 自托管部署步骤
 以下命令均在项目根目录执行。
 ### 1. 登录 Cloudflare
 项目建议使用本地 Wrangler：
 ```bash
 pnpm exec wrangler login
 pnpm exec wrangler whoami
 ```
 如果本地版本的 OAuth 登录出现 `invalid_scope` 等问题，可临时使用更新版本：
 ```bash
 pnpm dlx wrangler@latest login
 pnpm dlx wrangler@latest whoami
 ```
 登录注意事项：
 - 让 Wrangler 自动打开浏览器最稳妥；
 - 不要复用以前生成的 OAuth 链接；
 - 不要修改链接中的 `state`、`code_challenge` 或回调地址；
 - 不建议使用无痕窗口或跨浏览器复制链接；
 - 默认回调使用 `localhost:8976`，端口被占用时先结束旧的 Wrangler 登录进程；
 - 浏览器提示授权成功后，仍应通过 `whoami` 核对账号。
 ### 2. 修改 Worker 配置
 打开：
 ```text
 services/share-card-worker/wrangler.jsonc
 ```
 至少修改下面两个位置：
 ```jsonc
 {
  "routes": [
    {
      "pattern": "share.example.com",
      "custom_domain": true
    }
  ],
  "vars": {
    "PUBLIC_ORIGIN": "https://share.example.com",
    "DEFAULT_EXPIRY_DAYS": "7"
  }
 }
 ```
 `routes[].pattern` 是 Worker 自定义域名，`PUBLIC_ORIGIN` 是生成分享链接和校验签名来源时使用的完整 HTTPS 地址，两者必须一致。
 不要直接照抄仓库维护者的域名。请替换为你自己 Cloudflare 账号中的域名或子域名。
 ### 3. 创建私有 R2 Bucket
 默认配置使用 Bucket 名称：
 ```text
 wechatexplorer-share-reports
 ```
 创建：
 ```bash
 pnpm exec wrangler r2 bucket create wechatexplorer-share-reports \
  --config services/share-card-worker/wrangler.jsonc
 ```
 Worker 中的绑定名称是 `REPORTS`。R2 会保存：
 ```text
 cards/<card-id>/card.json
 cards/<card-id>/report.png
 cards/<card-id>/thumbnail.jpg
 ```
 - `card.json`：标题、描述、创建时间和过期时间；
 - `report.png`：完整日报长图；
 - `thumbnail.jpg`：微信卡片缩略图。
 请保持 R2 Bucket 私有，不要启用公开 `r2.dev` 开发 URL。图片应统一通过 Worker 的随机卡片 URL 读取。
 ### 4. 生成并配置 `UPLOAD_TOKEN`
 ```bash
 openssl rand -hex 32
 ```
 复制生成结果，然后执行：
 ```bash
 pnpm exec wrangler secret put UPLOAD_TOKEN \
  --config services/share-card-worker/wrangler.jsonc
 ```
 Wrangler 提示输入时粘贴密钥。终端不会正常显示 Secret 内容。
 ### 5. 配置微信 AppID 和 AppSecret
 从[微信公众平台接口测试号](https://mp.weixin.qq.com/debug/cgi-bin/sandboxinfo?action=showinfo&t=sandbox/index)复制 AppID：
 ```bash
 pnpm exec wrangler secret put WECHAT_APP_ID \
  --config services/share-card-worker/wrangler.jsonc
 ```
 再复制 AppSecret：
 ```bash
 pnpm exec wrangler secret put WECHAT_APP_SECRET \
  --config services/share-card-worker/wrangler.jsonc
 ```
 Secret 不会出现在 `wrangler.jsonc` 中。如果你更换 Cloudflare 账号或重新创建 Worker，需要重新配置全部三个 Secret。
 ### 6. 配置微信测试号
 在测试号页面完成：
 1. 使用测试微信关注该测试号；
 2. 将 `share.example.com` 填入“JS 接口安全域名”；
 3. 按页面提示完成 TXT 文件域名验证；
 4. 确认 AppID/AppSecret 与刚才写入 Worker 的值来自同一个测试号。
 测试号只适合开发和验证。正式公众号的接口权限、认证要求和后台菜单可能不同，请以微信公众平台实际规则为准。
 ### 7. 部署 Worker
 ```bash
 pnpm exec wrangler deploy \
  --config services/share-card-worker/wrangler.jsonc
 ```
 Cloudflare Custom Domain 要求域名已经位于同一 Cloudflare 账号中。如果该子域名已经存在 A、AAAA 或 CNAME 记录，绑定可能失败。删除冲突记录，或者换一个未使用的子域名，例如 `share2.example.com`。
 更新 Secret 后，如果线上仍提示旧配置，可再执行一次完整部署。
 ## 在 TraceMemo 中配置
 生成一份日报后，点击“生成微信卡片（实验性）”。首次使用需要填写：
 ```text
 服务地址：https://share.example.com
 上传密钥：你自己通过 openssl rand -hex 32 生成的 UPLOAD_TOKEN
 ```
 这里的“上传密钥”绝对不是微信 AppSecret。
 配置保存后，TraceMemo 会上传当前日报和缩略图，返回二维码。使用已经关注测试号的微信扫码，打开页面后再通过右上角菜单分享。
 ## 验证部署
 ### 健康检查
 ```bash
 curl -fsS https://share.example.com/health
 ```
 正常结果类似：
 ```json
 { "ok": true, "service": "wechatexplorer-share-card", "storage": "ready" }
 ```
 ### JS-SDK 签名检查
 ```bash
 curl -fsS \
  'https://share.example.com/api/wx-signature?url=https%3A%2F%2Fshare.example.com%2Fhealth'
 ```
 正常结果应包含：
 ```text
 appId
 timestamp
 nonceStr
 signature
 ```
 响应中不应包含 AppSecret、`access_token` 或 `jsapi_ticket`。
 ## 常见问题
 ### HTTP 401 / 未授权
 TraceMemo 中保存的上传密钥与 Worker 的 `UPLOAD_TOKEN` 不一致。重新生成或重新配置时，必须同步更新两边。
 ### “微信 JS-SDK 尚未配置”
 Worker 缺少 `WECHAT_APP_ID` 或 `WECHAT_APP_SECRET`。执行两个 `secret put`，再重新部署。
 ### `invalid signature` 或分享信息不生效
 依次检查：
 - `PUBLIC_ORIGIN` 是否与浏览器实际访问的 origin 完全一致；
 - JS 接口安全域名是否只填写了域名；
 - AppID/AppSecret 是否属于同一个测试号；
 - AppSecret 是否已被重置但 Worker 仍保存旧值；
 - 分享页面是否经过了改变 URL 的代理或重定向；
 - 测试微信是否已关注测试号。
 ### 自定义域名绑定失败
 检查同名 A、AAAA、CNAME 记录是否已经存在，域名是否位于当前 Wrangler 登录的 Cloudflare 账号中。
 ### R2 未配置
 确认 Bucket 存在，并且 `wrangler.jsonc` 中的绑定名称为 `REPORTS`、`bucket_name` 与实际 Bucket 一致。
 ### 卡片过期或图片消失
 默认有效期为 7 天。Worker 的定时任务会删除过期卡片的元数据、日报和缩略图，这是设计行为。
 ## 安全和隐私注意事项
 - 日报可能包含敏感群聊内容。只分享你有权分享的内容。
 - 获得分享 URL 的人，在过期前可能查看对应日报；当前实现不是按访问者身份授权。
 - `UPLOAD_TOKEN` 是整个 Worker 的服务级密钥，不是每个用户独立的账号凭据。
 - 不要把 `UPLOAD_TOKEN`、AppSecret 或 Wrangler 凭据提交到 Git。
 - R2 保持私有，不要把 Bucket 直接公开。
 - 建议定期轮换 `UPLOAD_TOKEN`，怀疑泄露时立即轮换。
 - 微信 AppSecret 泄露时，应在微信后台重置，并立即更新 Worker Secret。
 - 自托管者自行承担 Cloudflare 用量、域名、数据合规和微信平台规则相关责任。
 ## 当前实验性限制
 - 需要用户自己部署，普通用户无法直接开箱使用；
 - 使用一个共享的 `UPLOAD_TOKEN`，没有多用户账号系统；
 - 分享链接在有效期内属于“知道链接即可访问”；
 - 依赖微信 JS-SDK 和测试号能力，微信侧规则变化可能造成失效；
 - 当前仅上传 PNG 日报和 JPEG 缩略图；
 - 没有管理后台用于列出、提前删除或审计所有卡片；
 - 过期清理由定时任务完成，不保证到期瞬间立即删除。

 # 部署微信分享卡片
 尽量自行发现项目状态并完成部署。只在自动检查后仍缺少必要信息时，一次性询问用户；不要逐项反复确认。
 ## 安全边界
 - 不把真实 AppSecret、`UPLOAD_TOKEN`、Cloudflare Token 或微信验证内容写入 Git。
 - `.env.example` 只保存占位符；真实值写入项目根目录 `.env`，该文件必须被 Git 忽略。
 - 不在最终回答中回显 Secret。日志中只报告“已配置/缺失”。
 - `UPLOAD_TOKEN` 默认自动生成，不要求用户提供。
 - AppID/AppSecret 必须来自用户自己的微信测试号或公众号。无法自动获取时才询问。
 - 部署、创建 R2 和写 Secret 属于用户明确请求本 Skill 后的正常动作；不要提交、推送或创建 PR，除非用户另外明确要求。
 ## 自动工作流
 1. 定位 TraceMemo 仓库根目录。确认存在 `services/share-card-worker/wrangler.jsonc`。
 2. 运行：
   ```bash
   bash docs/skill/setup-wechat-share-card/scripts/setup.sh doctor
   ```
 3. 检查根目录 `.env`。脚本会自动复用已有配置并生成缺失的 `WECHAT_SHARE_UPLOAD_TOKEN`。
 4. 如果以下值缺失，只向用户发起一次集中询问：
   - 分享域名，例如 `share.example.com`；
   - 微信测试号 AppID；
   - 微信测试号 AppSecret。
 5. 用户不知道从哪里获取时，告诉他打开：
   ```text
   https://mp.weixin.qq.com/debug/cgi-bin/sandboxinfo?action=showinfo&t=sandbox/index
   ```
   使用微信扫码登录后，复制页面上的 `appID` 和 `appsecret`。提醒用户把分享域名填入“JS 接口安全域名”，不带 `https://` 和路径。
 6. 将缺失值交给交互脚本，不要把 Secret 放进命令行参数：
   ```bash
   bash docs/skill/setup-wechat-share-card/scripts/setup.sh configure
   ```
   该命令通过终端交互收集缺项，AppSecret 使用隐藏输入。
 7. 执行完整部署：
   ```bash
   bash docs/skill/setup-wechat-share-card/scripts/setup.sh deploy
   ```
   脚本会依次：
   - 检查或临时下载 Wrangler；
   - 启动 Cloudflare OAuth 登录；
   - 执行 `whoami`；
   - 生成本地 `wrangler.local.jsonc`；
   - 创建或复用 R2 Bucket；
   - 写入三个 Worker Secret；
   - 部署 Worker；
   - 检查 `/health` 和微信签名接口。
 8. OAuth 页面出现时，让用户只完成浏览器登录/授权；不要改用 API Token，除非用户主动要求。
 9. 部署后把服务地址告诉用户，并提醒他在 TraceMemo 卡片弹窗粘贴 `.env` 中的 `WECHAT_SHARE_UPLOAD_TOKEN`。优先把 Token 复制到剪贴板，不在聊天中展示：
   ```bash
   bash docs/skill/setup-wechat-share-card/scripts/setup.sh copy-token
   ```
 10. 如果微信要求 TXT 验证文件，读取 [references/wechat-domain-verification.md](references/wechat-domain-verification.md)，取得用户提供的文件后再修改 Worker。
 ## 决策规则
 - Wrangler 未安装：优先使用项目依赖；否则通过 `pnpm dlx wrangler@latest` 临时下载，不强制全局安装。
 - `whoami` 已登录正确账号：不要重复登录。
 - R2 已存在：继续，不把“已存在”视为失败。
 - 自定义域名有 A/AAAA/CNAME 冲突：报告准确域名并要求用户选择删除冲突记录或换子域名；不要擅自删除 DNS。
 - HTTP 401：重新同步 `.env` 中的 `WECHAT_SHARE_UPLOAD_TOKEN` 到 Worker，再让用户更新 TraceMemo。
 - “微信 JS-SDK 尚未配置”：重新写入 AppID/AppSecret 并部署。
 - 微信返回 AppID/AppSecret 错误：让用户检查是否来自同一个测试号、AppSecret 是否已重置。
 - 缺少 JS 接口安全域名或测试号关注：这是微信后台操作，明确告诉用户要填写什么，不要假装已完成。
 ## 验证结果
 完成前必须确认：
 - `wrangler whoami` 成功；

 # 微信域名验证文件
 当微信测试号页面要求下载 TXT 文件时：
 1. 向用户索取 TXT 文件本身，或文件名与完整内容。
 2. 不把真实验证内容写进公开仓库历史。
 3. 优先在本地私有配置中注入；若当前 Worker 只能通过源码 Map 返回，则先提醒用户该值会进入工作区，确认仓库发布前必须移除或改造成 Secret/变量。
 4. 验证目标必须是：
   ```text
   https://<分享域名>/<微信提供的文件名>.txt
   ```
 5. 返回内容必须是纯文本且与微信提供内容完全一致，不加空格、HTML 或额外换行。
 6. 完成验证后再配置 JS 接口安全域名。安全域名只填主机名，不带协议或路径。

 当 `/chatlog` 返回图片消息时：
 1. 如果用户只是询问图片消息是否存在，不需要获取图片。
 2. 如果用户要求查看、识别、理解或分析图片，使用该消息 `media.url`（`/media/{messageId}`）获取真实图片。

                    GNU GENERAL PUBLIC LICENSE
                       Version 3, 29 June 2007
 Copyright (C) 2026 yincongcyincong
 Everyone is permitted to copy and distribute verbatim copies
 of this license document, but changing it is not allowed.
                            Preamble
  The GNU General Public License is a free, copyleft license for
 software and other kinds of works.
  The licenses for most software and other practical works are designed
 to take away your freedom to share and change the works.  By contrast,
 the GNU General Public License is intended to guarantee your freedom to
 share and change all versions of a program--to make sure it remains free
 software for all its users.  We, the Free Software Foundation, use the
 GNU General Public License for most of our software; it applies also to
 any other work released this way by its authors.  You can apply it to
 your programs, too.
  When we speak of free software, we are referring to freedom, not
 price.  Our General Public Licenses are designed to make sure that you
 have the freedom to distribute copies of free software (and charge for
 them if you wish), that you receive source code or can get it if you
 want it, that you can change the software or use pieces of it in new
 free programs, and that you know you can do these things.
  To protect your rights, we need to prevent others from denying you
 these rights or asking you to surrender the rights.  Therefore, you have
 certain responsibilities if you distribute copies of the software, or if
 you modify it: responsibilities to respect the freedom of others.
  For example, if you distribute copies of such a program, whether
 gratis or for a fee, you must pass on to the recipients the same
 freedoms that you received.  You must make sure that they, too, receive
 or can get the source code.  And you must show them these terms so they
 know their rights.
  Developers that use the GNU GPL protect your rights with two steps:
 (1) assert copyright on the software, and (2) offer you this License
 giving you legal permission to copy, distribute and/or modify it.
  For the developers' and authors' protection, the GPL clearly explains
 that there is no warranty for this free software.  For both users' and
 authors' sake, the GPL requires that modified versions be marked as
 changed, so that their problems will not be attributed erroneously to
 authors of previous versions.
  Some devices are designed to deny users access to install or run
 modified versions of the software inside them, although the manufacturer
 can do so.  This is fundamentally incompatible with the aim of
 protecting users' freedom to change the software.  The systematic
 pattern of such abuse occurs in the area of products for individuals to
 use, which is precisely where it is most unacceptable.  Therefore, we
 have designed this version of the GPL to prohibit the practice for those
 products.  If such problems arise substantially in other domains, we
 stand ready to extend this provision to those domains in future versions
 of the GPL, as needed to protect the freedom of users.
  Finally, every program is threatened constantly by software patents.
 States should not allow patents to restrict development and use of
 software on general-purpose computers, but in those that do, we wish to
 avoid the special danger that patents applied to a free program could
 make it effectively proprietary.  To prevent this, the GPL assures that
 patents cannot be used to render the program non-free.
  The precise terms and conditions for copying, distribution and
 modification follow.
                       TERMS AND CONDITIONS
  0. Definitions.
  "This License" refers to version 3 of the GNU General Public License.
  "Copyright" also means copyright-like laws that apply to other kinds of
 works, such as semiconductor masks.
  "The Program" refers to any copyrightable work licensed under this
 License.  Each licensee is addressed as "you".  "Licensees" and
 "recipients" may be individuals or organizations.
  To "modify" a work means to copy from or adapt all or part of the work
 in a fashion requiring copyright permission, other than the making of an
 exact copy.  The resulting work is called a "modified version" of the
 earlier work or a work "based on" the earlier work.
  A "covered work" means either the unmodified Program or a work based
 on the Program.
  To "propagate" a work means to do anything with it that, without
 permission, would make you directly or secondarily liable for
 infringement under applicable copyright law, except executing it on a
 computer or modifying a private copy.  Propagation includes copying,
 distribution (with or without modification), making available to the
 public, and in some countries other activities as well.
  To "convey" a work means any kind of propagation that enables other
 parties to make or receive copies.  Mere interaction with a user through
 a computer network, with no transfer of a copy, is not conveying.
  An interactive user interface displays "Appropriate Legal Notices"
 to the extent that it includes a convenient and prominently visible
 feature that (1) displays an appropriate copyright notice, and (2)
 tells the user that there is no warranty for the work (except to the
 extent that warranties are provided), that licensees may convey the
 work under this License, and how to view a copy of this License.  If
 the interface presents a list of user commands or options, such as a
 menu, a prominent item in the list meets this criterion.
  1. Source Code.
  The "source code" for a work means the preferred form of the work
 for making modifications to it.  "Object code" means any non-source
 form of a work.
  A "Standard Interface" means an interface that either is an official
 standard defined by a recognized standards body, or, in the case of
 interfaces specified for a particular programming language, one that
 is widely used among developers working in that language.
  The "System Libraries" of an executable work include anything, other
 than the work as a whole, that (a) is included in the normal form of
 packaging a Major Component, but which is not part of that Major
 Component, and (b) serves only to enable use of the work with that
 Major Component, or to implement a Standard Interface for which an
 implementation is available to the public in source code form.  A
 "Major Component", in this context, means a major essential component
 (kernel, window system, and so on) of the specific operating system
 (if any) on which the executable work runs, or a compiler used to
 produce the work, or an object code interpreter used to run it.
  The "Corresponding Source" for a work in object code form means all
 the source code needed to generate, install, and (for an executable
 work) run the object code and to modify the work, including scripts to
 control those activities.  However, it does not include the work's
 System Libraries, or general-purpose tools or generally available free
 programs which are used unmodified in performing those activities but
 which are not part of the work.  For example, Corresponding Source
 includes interface definition files associated with source files for
 the work, and the source code for shared libraries and dynamically
 linked subprograms that the work is specifically designed to require,
 such as by intimate data communication or control flow between those
 subprograms and other parts of the work.
  The Corresponding Source need not include anything that users
 can regenerate automatically from other parts of the Corresponding
 Source.
  The Corresponding Source for a work in source code form is that
 same work.
  2. Basic Permissions.
  All rights granted under this License are granted for the term of
 copyright on the Program, and are irrevocable provided the stated
 conditions are met.  This License explicitly affirms your unlimited
 permission to run the unmodified Program.  The output from running a
 covered work is covered by this License only if the output, given its
 content, constitutes a covered work.  This License acknowledges your
 rights of fair use or other equivalent, as provided by copyright law.
  You may make, run and propagate covered works that you do not
 convey, without conditions so long as your license otherwise remains
 in force.  You may convey covered works to others for the sole purpose
 of having them make modifications exclusively for you, or provide you
 with facilities for running those works, provided that you comply with
 the terms of this License in conveying all material for which you do
 not control copyright.  Those thus making or running the covered works
 for you must do so exclusively on your behalf, under your direction
 and control, on terms that prohibit them from making any copies of
 your copyrighted material outside their relationship with you.
  Conveying under any other circumstances is permitted solely under
 the conditions stated below.  Sublicensing is not allowed; section 10
 makes it unnecessary.
  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
  No covered work shall be deemed part of an effective technological
 measure under any applicable law fulfilling obligations under article
 11 of the WIPO copyright treaty adopted on 20 December 1996, or
 similar laws prohibiting or restricting circumvention of such
 measures.
  When you convey a covered work, you waive any legal power to forbid
 circumvention of technological measures to the extent such circumvention
 is effected by exercising rights under this License with respect to
 the covered work, and you disclaim any intention to limit operation or
 modification of the work as a means of enforcing, against the work's
 users, your or third parties' legal rights to forbid circumvention of
 technological measures.
  4. Conveying Verbatim Copies.
  You may convey verbatim copies of the Program's source code as you
 receive it, in any medium, provided that you conspicuously and
 appropriately publish on each copy an appropriate copyright notice;
 keep intact all notices stating that this License and any
 non-permissive terms added in accord with section 7 apply to the code;
 keep intact all notices of the absence of any warranty; and give all
 recipients a copy of this License along with the Program.
  You may charge any price or no price for each copy that you convey,
 and you may offer support or warranty protection for a fee.
  5. Conveying Modified Source Versions.
  You may convey a work based on the Program, or the modifications to
 produce it from the Program, in the form of source code under the
 terms of section 4, provided that you also meet all of these conditions:
    a) The work must carry prominent notices stating that you modified
    it, and giving a relevant date.
    b) The work must carry prominent notices stating that it is
    released under this License and any conditions added under section
    7.  This requirement modifies the requirement in section 4 to
    "keep intact all notices".
    c) You must license the entire work, as a whole, under this
    License to anyone who comes into possession of a copy.  This
    License will therefore apply, along with any applicable section 7
    additional terms, to the whole of the work, and all its parts,
    regardless of how they are packaged.  This License gives no
    permission to license the work in any other way, but it does not
    invalidate such permission if you have separately received it.
    d) If the work has interactive user interfaces, each must display
    Appropriate Legal Notices; however, if the Program has interactive
    interfaces that do not display Appropriate Legal Notices, your
    work need not make them do so.
  A compilation of a covered work with other separate and independent
 works, which are not by their nature extensions of the covered work,
 and which are not combined with it such as to form a larger program,
 in or on a volume of a storage or distribution medium, is called an
 "aggregate" if the compilation and its resulting copyright are not
 used to limit the access or legal rights of the compilation's users
 beyond what the individual works permit.  Inclusion of a covered work
 in an aggregate does not cause this License to apply to the other
 parts of the aggregate.
  6. Conveying Non-Source Forms.
  You may convey a covered work in object code form under the terms
 of sections 4 and 5, provided that you also convey the
 machine-readable Corresponding Source under the terms of this License,
 in one of these ways:
    a) Convey the object code in, or embodied in, a physical product
    (including a physical distribution medium), accompanied by the
    Corresponding Source fixed on a durable physical medium
    customarily used for software interchange.
    b) Convey the object code in, or embodied in, a physical product
    (including a physical distribution medium), accompanied by a
    written offer, valid for at least three years and valid for as
    long as you offer spare parts or customer support for that product
    model, to give anyone who possesses the object code either (1) a
    copy of the Corresponding Source for all the software in the
    product that is covered by this License, on a durable physical
    medium customarily used for software interchange, for a price no
    more than your reasonable cost of physically performing this
    conveying of source, or (2) access to copy the
    Corresponding Source from a network server at no charge.
    c) Convey individual copies of the object code with a copy of the
    written offer to provide the Corresponding Source.  This
    alternative is allowed only occasionally and noncommercially, and
    only if you received the object code with such an offer, in accord
    with subsection 6b.
    d) Convey the object code by offering access from a designated
    place (gratis or for a charge), and offer equivalent access to the
    Corresponding Source in the same way through the same place at no
    further charge.  You need not require recipients to copy the
    Corresponding Source along with the object code.  If the place to
    copy the object code is a network server, the Corresponding Source
    may be on a different server (operated by you or a third party)
    that supports equivalent copying facilities, provided you maintain
    clear directions next to the object code saying where to find the
    Corresponding Source.  Regardless of what server hosts the
    Corresponding Source, you remain obligated to ensure that it is
    available for as long as needed to satisfy these requirements.
    e) Convey the object code using peer-to-peer transmission, provided
    you inform other peers where the object code and Corresponding
    Source of the work are being offered to the general public at no
    charge under subsection 6d.
  A separable portion of the object code, whose source code is excluded
 from the Corresponding Source as a System Library, need not be
 included in conveying the object code work.
  A "User Product" is either (1) a "consumer product", which means any
 tangible personal property which is normally used for personal, family,
 or household purposes, or (2) anything designed or sold for incorporation
 into a dwelling.  In determining whether a product is a consumer product,
 doubtful cases shall be resolved in favor of coverage.  For a particular
 product received by a particular user, "normally used" refers to a
 typical or common use of that class of product, regardless of the status
 of the particular user or of the way in which the particular user
 actually uses, or expects or is expected to use, the product.  A product
 is a consumer product regardless of whether the product has substantial
 commercial, industrial or non-consumer uses, unless such uses represent
 the only significant mode of use of the product.
  "Installation Information" for a User Product means any methods,
 procedures, authorization keys, or other information required to install
 and execute modified versions of a covered work in that User Product from
 a modified version of its Corresponding Source.  The information must
 suffice to ensure that the continued functioning of the modified object
 code is in no case prevented or interfered with solely because
 modification has been made.
  If you convey an object code work under this section in, or with, or
 specifically for use in, a User Product, and the conveying occurs as
 part of a transaction in which the right of possession and use of the
 User Product is transferred to the recipient in perpetuity or for a
 fixed term (regardless of how the transaction is characterized), the
 Corresponding Source conveyed under this section must be accompanied
 by the Installation Information.  But this requirement does not apply
 if neither you nor any third party retains the ability to install
 modified object code on the User Product (for example, the work has
 been installed in ROM).
  The requirement to provide Installation Information does not include a
 requirement to continue to provide support service, warranty, or updates
 for a work that has been modified or installed by the recipient, or for
 the User Product in which it has been modified or installed.  Access to a
 network may be denied when the modification itself materially and
 adversely affects the operation of the network or violates the rules and
 protocols for communication across the network.
  Corresponding Source conveyed, and Installation Information provided,
 in accord with this section must be in a format that is publicly
 documented (and with an implementation available to the public in
 source code form), and must require no special password or key for
 unpacking, reading or copying.
  7. Additional Terms.
  "Additional permissions" are terms that supplement the terms of this
 License by making exceptions from one or more of its conditions.
 Additional permissions that are applicable to the entire Program shall
 be treated as though they were included in this License, to the extent
 that they are valid under applicable law.  If additional permissions
 apply only to part of the Program, that part may be used separately
 under those permissions, but the entire Program remains governed by
 this License without regard to the additional permissions.
  When you convey a copy of a covered work, you may at your option
 remove any additional permissions from that copy, or from any part of
 it.  (Additional permissions may be written to require their own
 removal in certain cases when you modify the work.)  You may place
 additional permissions on material, added by you to a covered work,
 for which you have or can give appropriate copyright permission.
  Notwithstanding any other provision of this License, for material you
 add to a covered work, you may (if authorized by the copyright holders of
 that material) supplement the terms of this License with terms:
    a) Disclaiming warranty or limiting liability differently from the
    terms of sections 15 and 16 of this License; or
    b) Requiring preservation of specified reasonable legal notices or
    author attributions in that material or in the Appropriate Legal
    Notices displayed by works containing it; or
    c) Prohibiting misrepresentation of the origin of that material, or
    requiring that modified versions of such material be marked in
    reasonable ways as different from the original version; or
    d) Limiting the use for publicity purposes of names of licensors or
    authors of the material; or
    e) Declining to grant rights under trademark law for use of some
    trade names, trademarks, or service marks; or
    f) Requiring indemnification of licensors and authors of that
    material by anyone who conveys the material (or modified versions of
    it) with contractual assumptions of liability to the recipient, for
    any liability that these contractual assumptions directly impose on
    those licensors and authors.
  All other non-permissive additional terms are considered "further
 restrictions" within the meaning of section 10.  If the Program as you
 received it, or any part of it, contains a notice stating that it is
 governed by this License along with a term that is a further
 restriction, you may remove that term.  If a license document contains
 a further restriction but permits relicensing or conveying under this
 License, you may add to a covered work material governed by the terms
 of that license document, provided that the further restriction does
 not survive such relicensing or conveying.
  If you add terms to a covered work in accord with this section, you
 must place, in the relevant source files, a statement of the
 additional terms that apply to those files, or a notice indicating
 where to find the applicable terms.
  Additional terms, permissive or non-permissive, may be stated in the
 form of a separately written license, or stated as exceptions;
 the above requirements apply either way.
  8. Termination.
  You may not propagate or modify a covered work except as expressly
 provided under this License.  Any attempt otherwise to propagate or
 modify it is void, and will automatically terminate your rights under
 this License (including any patent licenses granted under the third
 paragraph of section 11).
  However, if you cease all violation of this License, then your
 license from a particular copyright holder is reinstated (a)
 provisionally, unless and until the copyright holder explicitly and
 finally terminates your license, and (b) permanently, if the copyright
 holder fails to notify you of the violation by some reasonable means
 prior to 60 days after the cessation.
  Moreover, your license from a particular copyright holder is
 reinstated permanently if the copyright holder notifies you of the
 violation by some reasonable means, this is the first time you have
 received notice of violation of this License (for any work) from that
 copyright holder, and you cure the violation prior to 30 days after
 your receipt of the notice.
  Termination of your rights under this section does not terminate the
 licenses of parties who have received copies or rights from you under
 this License.  If your rights have been terminated and not permanently
 reinstated, you do not qualify to receive new licenses for the same
 material under section 10.
  9. Acceptance Not Required for Having Copies.
  You are not required to accept this License in order to receive or
 run a copy of the Program.  Ancillary propagation of a covered work
 occurring solely as a consequence of using peer-to-peer transmission
 to receive a copy likewise does not require acceptance.  However,
 nothing other than this License grants you permission to propagate or
 modify any covered work.  These actions infringe copyright if you do
 not accept this License.  Therefore, by modifying or propagating a
 covered work, you indicate your acceptance of this License to do so.
  10. Automatic Licensing of Downstream Recipients.
  Each time you convey a covered work, the recipient automatically
 receives a license from the original licensors, to run, modify and
 propagate that work, subject to this License.  You are not responsible
 for enforcing compliance by third parties with this License.
  An "entity transaction" is a transaction transferring control of an
 organization, or substantially all assets of one, or subdividing an
 organization, or merging organizations.  If propagation of a covered
 work results from an entity transaction, each party to that
 transaction who receives a copy of the work also receives whatever
 licenses to the work the party's predecessor in interest had or could
 give under the previous paragraph, plus a right to possession of the
 Corresponding Source of the work from the predecessor in interest, if
 the predecessor has it or can get it with reasonable efforts.
  You may not impose any further restrictions on the exercise of the
 rights granted or affirmed under this License.  For example, you may
 not impose a license fee, royalty, or other charge for exercise of
 rights granted under this License, and you may not initiate litigation
 (including a cross-claim or counterclaim in a lawsuit) alleging that
 any patent claim is infringed by making, using, selling, offering for
 sale, or importing the Program or any portion of it.
  11. Patents.
  A "contributor" is a copyright holder who authorizes use under this
 License of the Program or a work on which the Program is based.  The
 work thus licensed is called the contributor's "contributor version".
  A contributor's "essential patent claims" are all patent claims
 owned or controlled by the contributor, whether already acquired or
 hereafter acquired, that would be infringed by some manner, permitted
 by this License, of making, using, or selling its contributor version,
 but do not include claims that would be infringed only as a
 consequence of further modification of the contributor version.  For
 purposes of this definition, "control" includes the right to grant
 patent sublicenses in a manner consistent with the requirements of
 this License.
  Each contributor grants you a non-exclusive, worldwide, royalty-free
 patent license under the contributor's essential patent claims, to
 make, use, sell, offer for sale, import and otherwise run, modify and
 propagate the contents of its contributor version.
  In the following three paragraphs, a "patent license" is any express
 agreement or commitment, however denominated, not to enforce a patent
 (such as an express permission to practice a patent or covenant not to
 sue for patent infringement).  To "grant" such a patent license to a
 party means to make such an agreement or commitment not to enforce a
 patent against the party.
  If you convey a covered work, knowingly relying on a patent license,
 and the Corresponding Source of the work is not available for anyone
 to copy, free of charge and under the terms of this License, through a
 publicly available network server or other readily accessible means,
 then you must either (1) cause the Corresponding Source to be so
 available, or (2) arrange to deprive yourself of the benefit of the
 patent license for this particular work, or (3) arrange, in a manner
 consistent with the requirements of this License, to extend the patent
 license to downstream recipients.  "Knowingly relying" means you have
 actual knowledge that, but for the patent license, your conveying the
 covered work in a country, or your recipient's use of the covered work
 in a country, would infringe one or more identifiable patents in that
 country that you have reason to believe are valid.
  If, pursuant to or in connection with a single transaction or
 arrangement, you convey, or propagate by procuring conveyance of, a
 covered work, and grant a patent license to some of the parties
 receiving the covered work authorizing them to use, propagate, modify
 or convey a specific copy of the covered work, then the patent license
 you grant is automatically extended to all recipients of the covered
 work and works based on it.
  A patent license is "discriminatory" if it does not include within
 the scope of its coverage, prohibits the exercise of, or is
 conditioned on the non-exercise of one or more of the rights that are
 specifically granted under this License.  You may not convey a covered
 work if you are a party to an arrangement with a third party that is
 in the business of distributing software, under which you make payment
 to the third party based on the extent of your activity of conveying
 the work, and under which the third party grants, to any of the
 parties who would receive the covered work from you, a discriminatory
 patent license (a) in connection with copies of the covered work
 conveyed by you (or copies made from those copies), or (b) primarily
 for and in connection with specific products or compilations that
 contain the covered work, unless you entered into that arrangement,
 or that patent license was granted, prior to 28 March 2007.
  Nothing in this License shall be construed as excluding or limiting
 any implied license or other defenses to infringement that may
 otherwise be available to you under applicable patent law.
  12. No Surrender of Others' Freedom.
  If conditions are imposed on you (whether by court order, agreement or
 otherwise) that contradict the conditions of this License, they do not
 excuse you from the conditions of this License.  If you cannot convey a
 covered work so as to satisfy simultaneously your obligations under this
 License and any other pertinent obligations, then as a consequence you may
 not convey it at all.  For example, if you agree to terms that obligate you
 to collect a royalty for further conveying from those to whom you convey
 the Program, the only way you could satisfy both those terms and this
 License would be to refrain entirely from conveying the Program.
  13. Use with the GNU Affero General Public License.
  Notwithstanding any other provision of this License, you have
 permission to link or combine any covered work with a work licensed
 under version 3 of the GNU Affero General Public License into a single
 combined work, and to convey the resulting work.  The terms of this
 License will continue to apply to the part which is the covered work,
 but the special requirements of the GNU Affero General Public License,
 section 13, concerning interaction through a network will apply to the
 combination as such.
  14. Revised Versions of this License.
  The Free Software Foundation may publish revised and/or new versions of
 the GNU General Public License from time to time.  Such new versions will
 be similar in spirit to the present version, but may differ in detail to
 address new problems or concerns.
  Each version is given a distinguishing version number.  If the
 Program specifies that a certain numbered version of the GNU General
 Public License "or any later version" applies to it, you have the
 option of following the terms and conditions either of that numbered
 version or of any later version published by the Free Software
 Foundation.  If the Program does not specify a version number of the
 GNU General Public License, you may choose any version ever published
 by the Free Software Foundation.
  If the Program specifies that a proxy can decide which future
 versions of the GNU General Public License can be used, that proxy's
 public statement of acceptance of a version permanently authorizes you
 to choose that version for the Program.
  Later license versions may give you additional or different
 permissions.  However, no additional obligations are imposed on any
 author or copyright holder as a result of your choosing to follow a
 later version.
  15. Disclaimer of Warranty.
  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
 APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
 HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
 OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
 THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
 PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
 IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
 ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
  16. Limitation of Liability.
  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
 THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
 GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
 USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
 DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
 PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
 EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
 SUCH DAMAGES.
  17. Interpretation of Sections 15 and 16.
  If the disclaimer of warranty and limitation of liability provided
 above cannot be given local legal effect according to their terms,
 reviewing courts shall apply local law that most closely approximates
 an absolute waiver of all civil liability in connection with the
 Program, unless a warranty or assumption of liability accompanies a
 copy of the Program in return for a fee.
                     END OF TERMS AND CONDITIONS
            How to Apply These Terms to Your New Programs
  If you develop a new program, and you want it to be of the greatest
 possible use to the public, the best way to achieve this is to make it
 free software which everyone can redistribute and change under these terms.
  To do so, attach the following notices to the program.  It is safest
 to attach them to the start of each source file to most effectively
 state the exclusion of warranty; and each file should have at least
 the "copyright" line and a pointer to where the full notice is found.
    <one line to give the program's name and a brief idea of what it does.>
    Copyright (C) <year>  <name of author>
    This program is free software: you can redistribute it and/or modify
    it under the terms of the GNU General Public License as published by
    the Free Software Foundation, either version 3 of the License, or
    (at your option) any later version.
    This program is distributed in the hope that it will be useful,
    but WITHOUT ANY WARRANTY; without even the implied warranty of
    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
    GNU General Public License for more details.
    You should have received a copy of the GNU General Public License
    along with this program.  If not, see <https://www.gnu.org/licenses/>.
 Also add information on how to contact you by electronic and paper mail.
  If the program does terminal interaction, make it output a short
 notice like this when it starts in an interactive mode:
    <program>  Copyright (C) <year>  <name of author>
    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
    This is free software, and you are welcome to redistribute it
    under certain conditions; type `show c' for details.
 The hypothetical commands `show w' and `show c' should show the appropriate
 parts of the General Public License.  Of course, your program's commands
 might be different; for a GUI interface, you would use an "about box".
  You should also get your employer (if you work as a programmer) or school,
 if any, to sign a "copyright disclaimer" for the program, if necessary.
 For more information on this, and how to apply and follow the GNU GPL, see
 <https://www.gnu.org/licenses/>.
  The GNU General Public License does not permit incorporating your program
 into proprietary programs.  If your program is a subroutine library, you
 may consider it more useful to permit linking proprietary applications with
 the library.  If this is what you want to do, use the GNU Lesser General
 Public License instead of this License.  But first, please read
 <https://www.gnu.org/licenses/why-not-lgpl.html>.

 # WechatExplorer share-card worker
 Cloudflare Worker + private R2 service for temporary WeChat report cards.
 This is an experimental, self-hosted feature. See the complete Chinese deployment guide:
 - `../../docs/deployment/experimental-wechat-share-card.md`
 Required encrypted secrets:
 - `WECHAT_APP_ID`
 - `WECHAT_APP_SECRET`
 - `UPLOAD_TOKEN` (random 32+ character token also saved in WechatExplorer's secure settings)
 Create the private bucket, set secrets, and deploy:
 ```bash
 npx wrangler r2 bucket create wechatexplorer-share-reports
 npx wrangler secret put WECHAT_APP_ID
 npx wrangler secret put WECHAT_APP_SECRET
 npx wrangler secret put UPLOAD_TOKEN
 npx wrangler deploy
 ```
 Keep the R2 public development URL disabled. All reads go through the Worker and expire with
 the card.
