+## 2026-05-12 微信小程序待绑定手机号优先走原生手机号授权
+
+- 背景：微信小程序 `web-view` 壳登录后若返回 `pending_bind_phone`，H5 仍会展示手输手机号和短信验证码绑定页，体验上多了一步。
+- 决策：小程序壳在 `pending_bind_phone` 时暂不打开 H5，先展示原生 `button open-type="getPhoneNumber"`；用户同意后把 `bindgetphonenumber` 返回的 `code` 作为 `wechatPhoneCode` 调用 `/api/auth/wechat/bind-phone`。后端通过微信 `stable_token` 与 `getuserphonenumber` 换取平台验证后的手机号，再复用现有微信待绑定账号合并逻辑并重新签发 active 系统 token。H5 旧短信验证码绑定流程继续作为非小程序环境兜底。
+- 影响范围：`miniprogram/pages/web-view/index.*`、`server-rs/crates/platform-auth`、`server-rs/crates/api-server/src/wechat_auth.rs`、认证共享契约、微信小程序 web-view 壳技术文档。
+- 验证方式：执行 `npm run check:encoding`、`node scripts/check-wechat-miniprogram-auth-smoke.mjs`、`cargo test -p shared-contracts wechat_bind_phone_request_accepts_mini_program_phone_code --manifest-path server-rs/Cargo.toml`、`cargo test -p api-server wechat_miniprogram_bind_phone_code_activates_pending_user --manifest-path server-rs/Cargo.toml -- --nocapture`。
