- WeightRecordsPage：cursor 分页（加载更多/末页收起/翻页失败保留重试）、 loading/empty/error/retry 四态、下拉刷新；viewer 隐藏录入入口 - WeightFormPage：weightKg 契约区间 (0,500] 与两位小数前端校验 + 40000 兜底；称重时间转 UTC 上送；错误三层分层沿用登录纵切 - health_record 域埋点强类型封装（06 §1.4：create_started/succeeded/ failed + viewed，httpStatus 由业务码推导；viewed 按工单口径取列表曝光） - health_record_display 纯函数（体重解析/展示、疫苗状态映射、42201 规则前端拦截函数）；PetsController 暴露 repository（22 号 §7 交接） - 测试 177 → 205（+28）全绿 Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
