## 背景
2026-09-13 UI 重设计方案的 13 个契约门禁中 3 个为红，逐一查明性质后分类处理。
## 1. activity 页迁移 TypeScript（11/11 页现已全 TS）
- activity.js → activity.ts（139 行），业务逻辑零改动，仅补类型
- 此前 STATUS.md 记「9/11 TS-only、3 页待迁」，但 messages/matchmaker
已在 4f91be0 迁完，实际只剩 activity 一页，本提交后清零
## 2. miniapp-reference-contracts 契约自身过期（非代码问题）
- 契约引用 messages.js / matchmaker.js / activity.js，但页面已 TS 化，
readFileSync 抛裸 ENOENT 栈，看不出「契约引用了陈旧文件名」这一真实原因
- 改为统一走 readPageLogic(page)：断言 .ts 存在 + .js 不存在（锁单一运行源），
找不到文件时给出可读断言而非崩溃
- 核心 11 页循环内统一加 TS-only 校验，防止 JS 回流
## 3. phase07-home-contracts 契约断言架构写反（非代码问题）
- 契约要求 HomeApplicationService 字面出现 userIdentityMapper.findByUserId，
但实际是 capabilityService.isIdentityVerified(userId)（HomeApplicationService:116）
- 这符合 AGENTS.md #26「前端入口可见性由服务端 CapabilityService 返回决定」，
让首页穿透 Capability 直接持有 mapper 反而是架构重复
- 且契约自身另一条已断言 CapabilityService 必须有 isIdentityVerified，
两条要求互相矛盾
- 改为：查库断言落在 caps 侧；首页断言必须委托 capabilityService.isIdentityVerified；
新增 doesNotMatch(home, /userIdentityMapper/) 禁止首页绕过 Capability
- 保留原有 doesNotMatch(home, /setVerified\(true\)/) 防硬编码断言
## 4. 新增 11 页静态预览器（本机无微信开发者工具）
- scripts/preview-miniapp.mjs：把 WXML + WXSS 转成可浏览器打开的静态 HTML
- 能力：wx:if/wx:elif/wx:else 链、wx:for 列表、嵌套三元、比较/取反运算、
自定义组件按属性展开、slot 替换、rpx→px 换算、组件样式收集
- mock 数据严格对齐 types/index.d.ts 与各页 WXML 实际读取字段
（如 regionName/heightCm/educationCode、status: registration_open），
不用想象字段，避免误导验收判断
- 产出 artifacts/ui-redesign/miniapp/preview.html（11 页可切换，284K）
- 明确边界：非真机渲染、不执行页面 JS、不连后端，
只用于视觉走查，不得作为功能验收证据
## 验证
- 契约门禁 12/13 通过（唯一红的 ui-document-baseline-contracts 涉及
STATUS.md 验收口径，待用户看真机效果后裁决，本轮不动）
- 11 页渲染体量：116/70/47/56/94/68/39/39/41/37/38 个类名元素，
零残留 {{}} 插值、零残留原始组件标签
- 小程序 tsc --noEmit 通过

/**
|
||
* 小程序页面静态预览生成器
|
||
*
|
||
* 用途：本机无微信开发者工具时，把 WXML + WXSS 转成可浏览器打开的静态 HTML，
|
||
* 用于核对布局、配色、区块顺序是否符合参考图语言。
|
||
*
|
||
* 明确边界（不得混淆）：
|
||
* - 这不是真机渲染，不执行页面 JS 逻辑，不连后端 API
|
||
* - wx:if / wx:for 按注入的 mock 数据求值；数据由 MOCK 按页面提供
|
||
* - 组件（ui-*）以等效 HTML 结构近似呈现，样式取自组件自身 wxss
|
||
* - 结论只能用于视觉走查，不能作为「功能验收通过」的证据
|
||
*
|
||
* 用法：node scripts/preview-miniapp.mjs [页面名...]
|
||
* node scripts/preview-miniapp.mjs # 全部 11 页
|
||
* 产出：artifacts/ui-redesign/miniapp/preview.html（含页面切换）
