 # iOS Native 0.2.2
 
-0.2.2 构建 8 把「分组」这个实体从应用里彻底删掉，归类只靠标签；同时完成第二轮配色与图标重构，

+0.2.2 把「分组」这个实体从应用里彻底删掉，归类只靠标签；同时完成第二轮配色与图标重构，界面上
+不再出现蓝色。构建 9 是一轮收尾打磨：修掉消息中心发不出去信的按钮遮挡，补齐按钮层级，统一缺数据
+读数的写法，并把中性灰阶压成严格等色。页面能力、上游白名单与本地数据布局见现行说明
+[docs/ios-native.md](ios-native.md)，
 本文只记录本次发布的变化。
 
 ## 本次变更
 
+- 中性灰阶改为严格 R=G=B：此前所有灰底的蓝通道比红通道高 3~10 级，浅色主题下大面积文字与描边
+  会蒙一层冷调，截图取色仍落在蓝色波段。现在画布、卡片、控件、描边、文字全部等色，画面里
+  只剩红（危险）、橙（告警）、绿（正常）三类状态色。
+- 延迟量表改为可读量：详情页延迟进度条此前恒为满格，38ms 和 900ms 画出来一模一样。现在与节点
+  卡片同一算法（越短越满，1s 归零），一根条真的在说延迟好坏。
+- 单位与占位写法统一：卡片里的延迟从 `218ms` 改成 `218 ms`，与概览、详情同一写法；设置页日志
+  计数与日志中心的 HTTP 状态占位也从 `--` 收敛到 `—`。
+- 表单里成对的控件同尺寸：标签输入框高 52，右侧加号按钮只有 44，两个控件并排时明显一高一矮。
+  现在加号与输入框同高同圆角。
+- 详情页身份信息对齐方式统一：头部摘要的值此前左对齐成一列，下方分区卡片的值右对齐，同一屏两种
+  排法读起来像两张不同的表。现在两处都靠右。
+- 修复消息中心无法发信：发送入口原先挂在页面底部的操作条上，而底部标签栏是用 `safeAreaInset`
+  贴在根视图上的，两者叠在同一位置，操作条整条被标签栏盖住，「发送消息」在真机上根本点不到。
+  现在发送与刷新一起放进导航栏右侧，节点总览、设置页同一区域同一套做法。
+- 主按钮禁用态重新分级：禁用前的主要按钮与普通按钮像素一致，表单里「取消」和「保存实例」分不出
+  主次。现在禁用的主要按钮改用主色低透明度底加同色描边，并去掉投影，看得见但明显弱于可用状态。
+- 消息行的删除按钮降噪：原先每条消息都带一枚红色实心方块按钮，一屏十几个红块。现在改成一个
+  红色线性图标，保留 44pt 点击区域，只在需要时提示危险语义。
+- 缺数据读数统一为一根短横：概览与卡片读数此前混用「不可用」和 `--`，四列窄格里既容易被读成
+  故障结论，字号还会被压缩。现在一律用 `—`，并按占位弱色渲染。
+- 应用图标金色再收一档：底部由深古铜提亮到香槟金，整块金属在高亮壁纸上不再往下沉成棕黄。
+  石墨底同步去掉 1 级的蓝通道偏差，1024 与 120 两档取色都不再落在蓝色波段。
+
 - 分组概念移除：删除分组视图、分组编辑器与分组仓储，实例模型不再有 `groupId`。升级后首次启动
   一次性删除 `Documents/instance-groups.json` 与偏好键 `fleet.groupMode`，本机不留死数据。
 - 标签接管归类：新增「批量标签」表，批量选择后一次给多台节点贴同一个标签；每个标签显示
