* 我的缘分页 U22(重构:用 matchStore + ui-user-card + ui-nav-bar)
|
||
*
|
||
* 3 Tab:互相喜欢(Mutual)/ 我喜欢的 / 喜欢我的(脱敏)
|
||
* 游标分页:下拉刷新 + onReachBottom 加载更多
|
||
* like-back:喜欢我的人 → 表达喜欢 → 若 Mutual 自动跳聊天
|
||
*
|
||
* 不变量(AGENTS.md):
|
||
* - 第 3 条:Mutual Match 后才能聊天——Mutual Tab 点击进入会话;未 Mutual 不可发起会话。
|
||
* - 第 6 条:单向意向不泄露——"喜欢我的"仅展示后端返回的脱敏字段(昵称/年龄/地区/是否已 Mutual),
|
||
* Store 与页面均不做二次身份还原。
|
||
* - 第 5 条:红娘不可替用户 Like——like-back 仅当前用户本人操作。
|
||
* - 第 9 条:PostgreSQL 是 Source of Truth——列表状态以 matchStore 同步服务端返回为准。
