 - 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。
