 - 2026-06-21 微信 WebView env 诊断日志收口：微信 `web-view` 壳读取小程序 envVersion 失败时只记录 `[web-view] read mini program env failed` 固定标签，不输出 `wx.getAccountInfoSync()` 原生异常对象；根级原生壳门禁拒绝恢复 `console.warn(..., error)`。
 - 2026-06-21 微信九宫切图诊断日志收口：微信 `share-grid` 壳下载封面、读取图片、导出切图、保存相册或最终保存流程失败时，只记录 `[share-grid] <stage>` 固定标签，不输出 `wx.downloadFile`、`wx.getImageInfo`、`wx.canvasToTempFilePath`、`wx.saveImageToPhotosAlbum` 或其它原生错误对象；页面仍只展示 `九宫切图保存失败。` 稳定文案。
 - 2026-06-21 微信支付与订阅诊断日志收口：微信支付参数解析、虚拟支付失败和订阅消息请求失败只记录 `[wechat-pay] <stage>` / `[subscribe-message] <stage>` 固定标签，不输出微信原生错误对象；H5 回灌继续只使用稳定 `wechat payment unavailable` / `wechat subscribe unavailable` 语义。
+- 2026-06-21 微信 WebView 认证诊断日志收口：微信 `web-view` 壳解析认证结果、`wx.login`、小程序登录请求、手机号绑定请求、认证流程和手机号授权拒绝失败时，只记录 `[web-view] <stage>` 固定标签，不输出微信原生错误对象、HTTP response 或授权 detail；页面仍只展示稳定登录 / 绑手机号错误文案。
 - 2026-06-19 微信壳路由一致性门禁：`npm run check:native-shells` 必须反查 `miniprogram/app.json.pages`、`miniprogram/host-bridge/protocol.js`、H5 `src/services/host-bridge/hostBridge.ts` 小程序页面常量、H5 `src/services/wechatMiniProgramSubscribe.ts` 订阅授权页面常量、`miniprogram/host-bridge/webView.js` 分享入口 / 分享消息类型、`miniprogram/config.js` source query / 域名格式、`miniprogram/shell/webView.js` 请求头来源标记、H5 runtime parser 和 H5 路由保留字段。新增或调整小程序页面、登录派生 URL、支付页、九宫切图页、订阅页、WebView 来源标记、H5 入口域名、API base URL 或宿主上下文 query 字段时，必须同步这几处常量并保持生产 / 开发域名都显式配置为纯 HTTPS domain；运行时开发域名回退生产域名只作为异常兜底。
 - 2026-06-18 登录 / 支付能力禁伪声明：`auth.requestLogin` 和 `payment.request` 保留在共享 HostBridge 契约中供未来真实接入，但 Expo / Tauri 壳在真实 SDK、渠道流程和后端契约落地前不得声明这些 capability，也不得把它们写入入口 URL `hostCapabilities`；两端检查脚本会拒绝伪声明，请求实际到达壳层时必须返回明确 `unsupported_method` 并让 H5 fallback，两端壳测试直接覆盖这两个 method。
 - 2026-06-20 桌面壳未声明 method 禁伪成功：Tauri 桌面壳只声明真实可用 capability；共享 HostBridge method 白名单中未进入桌面 capability profile 的 method，例如 `auth.requestLogin`、`payment.request`、`file.captureImage`、`scanner.scanQrCode` 和 `haptics.impact`，请求实际到达桌面壳时必须统一返回明确 `unsupported_method`，不得伪造成功或半接入。桌面 Rust 测试必须从 `HOST_BRIDGE_METHODS` 与 `capabilities()` 差集派生 unsupported 覆盖清单，桌面单端配置检查会反查该派生路径，后续共享契约新增 method 时必须同步声明真实桌面能力或补进 unsupported 语义。

 2026-06-19 追加：微信小程序壳路由一致性进入原生壳统一验收。`npm run check:native-shells` 会反查 `miniprogram/app.json.pages` 与 `miniprogram/host-bridge/protocol.js` 页面 URL 常量一致，H5 `src/services/host-bridge/hostBridge.ts` 的小程序登录、支付、九宫切图页面常量、H5 `src/services/wechatMiniProgramSubscribe.ts` 的订阅授权页面常量与微信协议常量一致，`miniprogram/host-bridge/webView.js` 的 WebView 分享入口和分享目标消息类型不漂移；同时会校验 `miniprogram/config.js` 的生产 / 开发 H5 入口与 API base URL 都是显式配置的纯 HTTPS 域名，`WEB_VIEW_SOURCE_QUERY` 与共享 `HOST_BRIDGE_WECHAT_MINI_PROGRAM_SOURCE_QUERY` 一致，`miniprogram/shell/webView.js` 请求头从 `WEB_VIEW_SOURCE_QUERY` 读取 `clientType` / `clientRuntime`，H5 runtime parser 读取共享 `HOST_BRIDGE_RUNTIME_CONTEXT_QUERY_KEY`，H5 路由保留字段读取共享 `HOST_BRIDGE_PRESERVED_RUNTIME_CONTEXT_QUERY_KEYS`。运行时对开发域名的生产域名回退只作为异常兜底，不作为配置口径；新增小程序页面、改页面路径、调整来源 query 或切换域名格式时，必须同步协议常量、H5 HostBridge / 订阅服务常量、`app.json`、共享 HostBridge query 契约和这条门禁。
 
 2026-06-18 追加：原生壳本地生成物不作为生产源码门禁输入。Expo `.expo/`、Expo export smoke 临时目录、Tauri `target/`、Tauri schema `gen/` 和 Tauri 自动生成权限目录都必须保持 gitignored；根级生产壳敏感词扫描只检查可提交的壳源码和配置，避免本机工具输出影响生产门禁。手写 capability / 权限配置仍需保留在扫描范围内。
