release(ios): 0.2.2 构建 10 修消息卡空洞、标签胶囊假宽与表单标题层级

- 消息卡片删除按钮移出正文行，改用 overlay 悬在右侧，44pt 点击区不再把行撑高
- 批量标签胶囊由等宽栅格改为流式布局，新增 AIFlowLayout 并让节点页复用同一实现
- 设置页应用信息补「构建」一行，版本号全程不带括号
- 添加实例与发送消息两张表单表统一行内标题，去掉大标题留下的空白带
- 节点空态文案改为「节点未返回设备信息」，与量表条实际返回的数据不矛盾
- 图标石墨底、面板阴影与插槽统一压暖 3~4 级，全图 0 蓝色像素

 一个用于聚合管理多个 [SimAdmin](https://github.com/3899/SimAdmin) 实例的轻量本地运维面板。
 
+## iOS Native 应用
+
+`apps/ios` 提供不依赖 8788 控制台的原生 iPhone 应用，当前版本 **0.2.2**，构建号 10，运行在 iOS 16 及以上，产物为未签名 IPA，供 TrollStore 或自有签名流程安装。iOS 开发在 `ios-native-ipa` 分支进行。
+
+底部为节点、消息、设置三个入口：
+
+- **节点**：运行概览、标签多选筛选、标签批量归类、搜索、批量选择、实例增删改，卡片直连实例详情。
+- **实例详情**：设备、SIM、蜂窝网络、系统资源、CPU、连接状态六个模块，敏感值默认脱敏，显示后离开页面即隐藏。
+- **消息**：跨实例短信读取、按实例与方向筛选、搜索、发送、删除。
+- **设置**：主题外观（跟随系统 / 浅色 / 深色）、应用信息、本地数据与日志中心、隐私与数据、数据清理。
+
+实例信息与密码保存在应用沙盒本地文件，会话 Cookie 只存在于进程内存，不使用 Keychain，不上传任何数据。应用只访问用户添加的节点地址，上游路径为固定白名单。
+
+按产品决策移除的能力：全局访问密码、定时与后台调度、iOS 远程推送、自动备份与自动清理、控制台自更新，以及依赖常驻进程的应用内通知中心（日志中心因此收进设置，不再单独占一个底部入口）。
+
+构建与自检：
+
+```bash
+./scripts/build-ios-ipa.sh        # 产出 build/ipa/MultiSimAdmin.ipa 与 .sha256
+cd apps/ios && swift test         # 48 个用例
+```
+
+文档：现行说明 [docs/ios-native.md](docs/ios-native.md)，发布记录 [0.2.2](docs/ios-native-0.2.2.md)、[0.2.1](docs/ios-native-0.2.1.md) 与 [0.2.0](docs/ios-native-0.2.0.md)。
+
 ## 功能
 
 - 只需要在 `config.json` 配置多个 SimAdmin 地址。

+// Renders the 1024x1024 MultiSimAdmin app icon with CoreGraphics only.
+// Usage: swift Design/generate_app_icon.swift <output.png>
+//
+// The mark is the web favicon grown up: a flat gold SIM plate with three
+// ascending slots cut out of it, on a neutral graphite field. Two colours, one
+// light source from the upper left, no metal texture, so it still reads at the
+// 29pt settings size. The plate keeps the classic single SIM cut, top-left.
+//
+// The field is warm-neutral, not mathematically neutral. A perfectly grey R=G=B
+// plate sitting next to saturated gold loses the comparison and reads cool on a
+// lit home screen — that is how "there is no blue in it" still looked "blue" to
+// the eye. Red runs 2..4 levels over blue instead, which is invisible as a cast
+// but impossible to misread. The gold stays warm and deep so it reads metal
+// rather than mustard.

+
+## 界面约定
+
+界面不含任何蓝色：主操作、选中态、进度填充一律用石墨墨色（`AITheme.primary` / `AITheme.ink`），
+颜色只留给状态语义——危险红、告警琥珀、成功绿，且只在真的表示状态时出现，健康读数保持墨色。
+选中态用实心主色加 `onPrimary` 文字，不用低透明度色雾，浅色深色两套主题下都必须一眼可读；
+同屏并排控件等高；选中态不得改变控件尺寸；标签统一 28pt 胶囊；卡片内部不再嵌套卡片，
+并列读数改用发丝线分隔的栅格；不得出现因配色而在深色背景上消失的按钮或文字。

+# iOS Native 0.2.0
+
+MultiSimAdmin 0.2.0 是面向 iPhone 的原生 IPA 版本。应用直接连接用户添加的 SimAdmin 节点，不需要先启动 8788 控制台。本文是历史发布说明，现行说明见 [docs/ios-native.md](ios-native.md)。
+
+## 本次变更
+
+- 底部导航精简为节点、消息、设置。
+- 日志中心完整移入“设置 → 本地数据”，保留运行日志、连接日志、设备诊断、筛选和清理能力。
+- 移除应用本地通知中心。通知依赖应用进程持续转发，不适合关闭后仍要求可用的场景。
+- 设置页提供全局主题切换：跟随系统、浅色、深色，切换状态立即作用于全部页面。
+- 隐私说明改为“隐私与数据”，明确节点信息、实例密码和登录会话的实际保存方式。
+- 节点详情重排为更清晰的状态、连接、SIM、设备和会话分区。
+- 应用图标重做为黑金风格。
+- 节点总览展示硬件、控制、SIM、蜂窝链路状态。
+- 分组头和节点详情头部使用固定尺寸指标卡，加载完成后不会跳变。
+- 节点总览工具栏统一为 44pt 圆角图标按钮，补齐无障碍标签。
+
+## 数据与安全
+
+- 实例信息保存在应用沙盒内的本地数据文件。
+- 实例密码保存在同一应用沙盒内的私有凭据文件，不使用 iOS Keychain。
+- 登录会话只保存在进程内存中，应用关闭后清除。
+- 应用仅连接用户添加的节点地址，允许 HTTP 是为了兼容局域网 SimAdmin；公网地址建议通过 HTTPS 反代暴露。
+
+## 构建与安装
+
+从仓库根目录构建：
+
+```bash
+./scripts/build-ios-ipa.sh
+```
+
+产物：
+
+- `build/ipa/MultiSimAdmin.ipa`
+- `build/ipa/MultiSimAdmin.ipa.sha256`
+
+0.2.0 构建 3 校验值：
+
+```text
+1ddba7399d74705a7d31835dc6dff30c3b2fc3b3cada23c68eaa84a8fb2c832f  MultiSimAdmin.ipa
+```
+
+IPA 目标为 iOS 16.0 及以上，`arm64`，Bundle ID 为 `fun.chick.multi-simadmin`。构建脚本不要求开发者证书，TrollStore 或自有签名流程可以后续处理。

+# iOS Native 0.2.1
+
+0.2.1 构建 6 在 0.2.0 的基础上做界面与图标重构，功能集合不变。应用的整体结构、页面能力、上游白名单和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
+
+- 应用图标重做：改用与 Web 端 favicon 同一套几何的扁平标记——金色 SIM 卡体加三格递增信号，左上保留 SIM 切角。放弃原先的照片级立体卡，29pt 设置图标下也能读清轮廓。
+- 标签形状统一：详情页与日志页的状态标签改为与节点卡片一致的胶囊，不再一处圆角矩形、一处胶囊。
+- 深色主题下标签可见性提高，色雾与描边权重上调，避免浅底可读、深底消失。
+- 消息卡片去掉分隔线并压缩内边距，单屏可见消息数由 2.5 条提升到 3.5 条。
+- 节点详情的分区卡片收紧行距，"设备"分区同一屏位由 3 行增加到 5 行。
+- 节点详情头部指标收敛为 4 枚仪表（信号、延迟、CPU、内存）与一行身份摘要（号码、运营商、网络、IP），设备型号、固件、存储、运行时间下沉到分区列表；数据模块由 6 枚胶囊改为一条可用度读数，只在真有模块读不到时展开并点名。
+- 批量选择勾选框移出实例名称区域，选中与未选中都不再压住文字。
+- 批量选择工具栏统一为 34pt 图标按钮，全选、删除、退出三个控件等高。
+- 分组编辑器改为点选即生效，去掉常驻禁用的"移出分组"按钮和说明文字。
+
+## 文档同步
+
+本次发布同时补齐了与实现脱节的说明文档：
+
+- 新增 [docs/ios-native.md](ios-native.md)，作为 iOS 应用的现行说明：导航、页面能力、上游接口白名单、本地数据与安全、构建与验证、已确认的移除边界。
+- [docs/superpowers/specs/2026-09-08-ios-native-ipa-design.md](superpowers/specs/2026-09-08-ios-native-ipa-design.md) 加上实现修订段，逐条标出被推翻的决策（五 Tab、通知中心、Keychain、GRDB/SQLite、操作与审计、设备模块范围、配色）。

+# iOS Native 0.2.2
+
+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。构建 10 继续收细节：消息卡片右侧的空洞、批量标签胶囊的
+假宽度、设置页读不出构建号、两张表单表的标题层级，以及图标石墨底的冷调。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
+  「未贴 / N/M / 全部」三态覆盖度，点击即在整批上加减，也可以在同一张表里新建标签。卡片与
+  标签条上的标签仍然可点，点一下即加入筛选。
+- 配色重构，全应用零蓝色：主操作、选中态、进度填充一律用石墨墨色，黄铜只作图标点缀；颜色
+  只保留给状态语义（危险红、告警琥珀、成功绿），健康读数回到墨色，深色主题不再整屏泛绿。
+  浅色主题重做为中性冷灰画布加纯白卡片，深色主题为低明度石墨三层。
+- 选中态可见性：主题切换块与状态图例胶囊原先用 10%~12% 色雾表示选中，浅色下几乎看不出来，
+  改为实心主色加 `onPrimary` 文字，两套主题都一眼可读，且选中不改变控件尺寸。
+- 应用图标重做：放弃立体卡与投影，改扁平石墨底加黄铜 SIM 面板，三根底部对齐的递增信号条，
+  29pt 下轮廓仍可读；面板边长、圆角、切角与信号条间距可用环境变量调参后重新光栅化。
+  底色与插槽改为严格等值的 R=G=B 中性石墨（原先偏青绿，在亮色壁纸上会被读成蓝），金色
+  下压饱和度、提高明度跨度，从浅金到深古铜，去掉「芥末黄」的塑料感。
+- 运行概览收紧：检测进度从读数格移进卡片副标题（`刚刚更新 · 已检测 6/6 台`）；读数栅格固定
+  八格两行，温度与电量即使整群节点都没上报也保留「不可用」占位，栅格不再在七格与九格之间跳；
+  概览量表健康时用墨色，只在告警与危险时上色。
+- 实例详情头部重排：四项仪表从四枚嵌套小卡改为两列发丝线栅格，读数在上、进度在下，缺数据时
+  保留空轨道，数据到位后卡片高度不变，修掉 0.2.1「加载完成后头部比下方窄一圈」的问题；身份摘要
+  去掉内嵌底色，改用顶部发丝线分隔。
+- 字段名补全：详情页里 `name`、`disk_total_bytes`、`disk_available_bytes`、`percent` 四个键
+  此前直接把原始键名渲染到界面上，现补为「设备名称」「存储总量」「可用存储」「使用率」并排进
+  固定顺序。
+- 标签与方向胶囊中性化：`AITag` 拆成两类——不传状态色时是中性归类胶囊（浅底、发丝描边、墨色
+  文字，可带图标），传状态色时才用色雾。详情页标签因此不再显示成近乎禁用的黑雾块，并与节点
+  卡片同一形状同一图标；消息中心的「收件 / 发件」由绿色改回中性胶囊配上下箭头，绿色重新只
+  表示健康状态。
+- 批量标签表在没有任何勾选时给出「先在节点列表勾选要归类的节点」提示，不再留一行空白。
+  同时这段状态下标签胶囊不再渲染成 `Button`：系统禁用态会把整枚胶囊压成灰块，看起来像加载
+  失败，现按中性标签原样显示，只把「新建标签并贴上」的输入与按钮置灰并说明原因。
+- 版本号显示去掉括号：设置页「应用信息」只显示 `0.2.2`。
+
+## 构建 10
+
+- 消息卡片右侧的空洞修掉：删除按钮此前和摘要挤在同一行 `HStack` 里，它自带 44pt 点击区，等于把
+  这一行撑高约 22pt，卡片下半截全是空白，一屏只能放三张。现在摘要行按正文列宽排版，删除按钮用
+  `overlay` 悬在右侧并溢出到卡片留白里，点击区仍是 44pt，一屏回到四张。
+- 批量标签的胶囊改成贴合文字宽度：原先用 `LazyVGrid` 等宽栅格，短标签被拉到 112pt 一格，看起来
+  像整片禁用的灰块。现在换成流式布局（`AIFlowLayout`），胶囊只占文字加内边距，节点页的标签条
+  复用同一份实现，删掉了原来那份重复的布局代码。
+- 设置页显示构建号：同一营销版本会连续出多个包，只写 `0.2.2` 分不清设备上装的是哪个。应用信息
+  现在是「版本 0.2.2 / 构建 10 / 系统 iOS 26.3.1」三行，全程不带括号。
+- 两张表单表统一行内标题：「添加实例」和「发送消息」用大标题，标题下方留出一整条空白，而同类的
+  「批量标签」已经是行内样式。现在三张表一致。
+- 节点卡片的空态文案不再自相矛盾：卡片下方的量表条确实会返回运行时数据，空态却写「节点未返回
+  运行信息」。改为「节点未返回设备信息」，与实际缺少的字段一致。
+- 图标底色压暖：石墨底原先是数学意义上的中性灰（R=G=B），在 iOS 浅色壁纸旁仍会被对比成冷调，
+  这是用户反馈「图标是蓝色」的直接来源（旧包 0.2.1 的图标确实有 72% 像素落在蓝色波段）。现在
+  底色、面板阴影与插槽统一带 3~4 级暖偏移，取色为 `rgb(47,45,42)`，全图 0 蓝色像素。
+
+## 文档同步
+
+- 新增本文，[docs/ios-native.md](ios-native.md) 同步到 0.2.2：导航表去掉分组视图，节点总览与
+  实例详情两节按实况重写，本地数据表删掉 `instance-groups.json`，设计语言一节改为石墨与墨色
+  中性、颜色只留给状态、不含蓝色，偏离表新增分组一行。
+- 仓库根 README 与 `apps/ios/README.md` 同步版本号、节点入口描述、目录说明与界面约定；界面
+  约定里「主操作只用一种蓝色」按本次结论改写。
+
+## 数据与安全
+
+与 0.2.1 一致：实例信息保存在应用沙盒本地数据文件，实例密码保存在同一沙盒的私有凭据文件，
+不使用 iOS Keychain，登录会话只存在于进程内存。应用仅连接用户添加的节点地址，不上传任何数据。
+本次新增的唯一数据动作是删除遗留的分组文件，不改动实例、标签与凭据内容。

+# iOS 原生应用说明（当前实现）
+
+本文是 iPhone 应用的唯一现行说明，内容与仓库代码一致。历史设计稿和执行计划保留在
+`docs/superpowers/` 下，其中已被实现推翻的决策在本文第 9 节逐条列出。
+
+- 当前版本：`0.2.2`，构建号 10
+- 承载分支：`ios-native-ipa`
+- 运行要求：iOS 16.0 及以上，`arm64`，Bundle ID `fun.chick.multi-simadmin`
+- 产物：未签名 `MultiSimAdmin.ipa`，由 TrollStore 或用户自有签名流程安装
+
+## 1. 形态
+
+独立 iPhone 应用。应用直接以 HTTP/HTTPS 访问用户添加的每个 SimAdmin 节点，不经过
+8788 控制台，不含 WebView，不内嵌 Node.js，也不与 Web 端共享数据库或进程。Web 前端和
+Node 控制面仍然独立存在，两者只共享上游接口契约。
+
+## 2. 导航
+
+底部固定三个入口，高度 62pt（`AITabBar`）：
+
+| 入口 | 页面 | 内容 |
+| --- | --- | --- |
+| 节点 | `FleetView` | 节点总览、运行概览、标签筛选与批量归类、批量选择、添加与编辑实例 |
+| 消息 | `MessagesView` | 跨实例短信读取、按实例与方向筛选、搜索、发送、删除 |
+| 设置 | `SettingsView` | 主题外观、应用信息、本地数据（进入日志中心）、隐私与数据、数据清理 |
+
+实例详情 `InstanceDetailView` 由节点卡片进入；日志中心 `LogsView` 只出现在
+「设置 → 本地数据」里，不占用底部入口。启动参数 `--tab-messages`、`--tab-settings`
+可直达对应 Tab，`--tab-detail`、`--tab-logs` 只在 Debug 构建生效，供逐页截图验证使用。
+
+## 3. 页面能力
+
+### 节点总览
+
+- 运行概览：在线率与异常节点两枚大字结论、状态分布条与图例、八格两行的群集读数（信号、延迟、
+  存储、流量、CPU、内存、温度、电量），可折叠，折叠时保留前四格。检测进度与更新时间写在卡片
+  副标题里（`刚刚更新 · 已检测 6/6 台`），不占读数格；整群节点没有上报的读数保留占位，统一写成
+  一根短横 `—`，避免在四列窄格里被读成故障结论；栅格不会在七格与九格之间跳动。
+- 标签归类：标签是唯一归类手段，分组概念已在 0.2.2 移除。标签条支持多选叠加，胶囊上直接显示
+  命中台数，可单个取消或全部清除；卡片内的标签同样可点，点一下即加入筛选。
+- 批量标签：批量选择后一次给多台节点贴同一个标签，每个标签显示「未贴 / N/M / 全部」三态覆盖度，
+  点击即在整批上加减；可在同一张表里新建标签。
+- 搜索：匹配名称、地址、运营商与标签。
+- 节点卡片：顶部四条量表（信号、延迟、CPU、内存）配发丝进度，下面是号码、运营商、设备、存储、
+  温度、电量、运行时间等指标，超出一屏时折叠为「另有 N 项指标」。健康读数不着色，只有越过阈值
+  才出现告警或危险色。
+- 批量选择：工具栏为 34pt 图标按钮（全选、删除、退出等高），勾选列独立于名称区域，
+  选中态不遮挡文字。
+- 实例增删改：地址、名称、标签、访问凭据；删除前确认，并一并清除本地登录信息。
+
+### 实例详情
+
+- 头部卡片：地址与连接状态、四项仪表（信号、延迟、CPU、内存）、身份摘要（号码、运营商、网络、
+  IP）、模块可用度读数、标签。四项仪表排成两列发丝线栅格，读数在上、进度在下，缺数据时保留
+  空轨道，数据到位后卡片高度不变。
+- 数据模块：设备、SIM、蜂窝网络、系统资源、CPU、连接状态共 6 个分区，逐模块独立加载，
+  单模块失败只标记该模块，不影响其余分区。
+- 敏感值（IMEI、ICCID 等）默认隐藏，需要显式开启显示，离开页面后自动恢复隐藏。
+- 本机保存的配置：地址、凭据状态、标签，以及登录、登出、重新检测。
+
+### 消息中心
+
+逐实例读取 `/api/sms/list` 后在本地合并，不做跨设备中转：
+
+- 列表按时间排序，显示来源实例、方向、号码、正文与相对时间。
+- 支持按实例筛选、按上行/下行筛选、按号码或内容搜索。
+- 发送与刷新一起放在导航栏右侧，页脚不再另挂操作条；发送写入目标实例，失败可重试；
+  单条删除走该实例的上游接口，行内只留一枚红色线性图标。
+
+### 日志中心与设置
+
+- 日志中心：运行日志统一时间线、连接探测记录（结果、错误码、耗时）、设备诊断快照；
+  支持按级别、来源、实例、结果筛选与关键字搜索，支持清理过期连接日志。
+- 设置：主题外观（跟随系统、浅色、深色，即时作用于全部页面）、应用信息与系统版本、
+  本地数据统计、隐私与数据说明、清除运行日志（不可恢复确认）。
+
+## 4. 上游访问
+
+只允许固定白名单，不存在任意 URL 代理：
+
+| 方法 | 路径 | 用途 |
+| --- | --- | --- |
+| GET | `/api/health` | 可达性与版本 |
+| GET | `/api/device` | 设备信息 |
+| GET | `/api/sim` | SIM 与号码 |
+| GET | `/api/network` | 蜂窝网络与信号 |
+| GET | `/api/network/signal-strength` | 信号强度明细 |
+| GET | `/api/stats` | 系统资源 |
+| GET | `/api/stats/cpu` | CPU 明细 |
+| GET | `/api/connectivity` | 连接状态 |
+| GET | `/api/sms/list` | 短信列表（limit、offset、direction） |
+| POST | `/api/sms/send` | 发送短信 |
+| POST | `/api/sms/batch-delete` | 批量删除短信 |
+| POST | `/api/auth/login` | 使用实例密码换取会话 |
+| POST | `/api/auth/logout` | 注销会话 |
+
+请求超时 30 秒，单响应体上限 262144 字节，错误统一映射为请求非法、需要登录、权限受限、不支持、
+超时、传输失败、响应非法七类可读文案。会话 Cookie 按实例隔离保存在内存中，并绑定创建时
+的节点地址，地址改变后旧 Cookie 立即失效。应用不请求定位、相机、麦克风、通讯录或后台
+刷新权限，不声明任何后台模式。
+
+## 5. 本地数据与安全
+
+全部数据落在应用沙盒 `Documents` 目录，无 Keychain、无 SQLite、无服务端上传：
+
+| 文件 | 内容 |
+| --- | --- |
+| `instances.json` | 实例名称、地址、标签、修订号 |
+| `credentials.json` | 实例访问密码 |
+| `log-center.json` | 运行日志、连接探测记录、诊断快照缓存 |
+
+0.2.1 及更早版本写过的 `instance-groups.json` 与偏好键 `fleet.groupMode` 在升级后的首次启动
+一次性删除。主题偏好存在 `UserDefaults`（键 `aiThemeMode`）。登录会话只存在于进程内存，应用退出即消失。
+密码与 Cookie 不写日志、不进导出内容。删除应用即彻底清除本机数据。允许 HTTP 明文访问是
+为了兼容局域网 SimAdmin，公网节点应由用户自行通过 HTTPS 反代暴露。
+
+## 6. 设计语言
+
+界面不含蓝色。品牌色是石墨与黄铜：浅色画布中性冷灰 `#F4F5F5`、纯白卡片、墨黑主操作
+`#151819`；深色画布 `#080909`、低明度石墨分层 `#131515` / `#1B1D1E`、近白主操作 `#EEF1F1`。
+颜色只保留给状态语义——危险 `#C12E28` / `#F77169`、告警 `#AA5C0F` / `#E9A63C`、成功
+`#107A56` / `#42C784`，健康读数一律用墨色，避免整屏泛绿或整屏泛红。选中态用实心主色加
+`onPrimary` 文字，不使用低透明度色雾，浅色深色两套主题下都必须一眼可读。
+
+控件令牌集中在 `AITheme`：主按钮高 48pt（紧凑 44pt、大号 56pt）、工具栏按钮高 44pt（宽 104pt）、
+导航栏图标按钮 34pt 方形（圆角 11pt）、输入框高 52pt、卡片圆角 22pt、按钮圆角 16pt、标签为
+28pt 胶囊。同屏并排控件必须等高，选中态不得改变控件尺寸，卡片内部不再嵌套卡片——并列读数改用
+发丝线分隔的栅格，正文与标题不使用负字距，字距为 0。
+
+## 7. 构建与产物
+
+```bash
+./scripts/build-ios-ipa.sh
+```
+
+流程：`xcodebuild -scheme MultiSimAdmin -configuration Release`（`generic/platform=iOS`）编译
+可执行文件 → 手工组装 `Payload/MultiSimAdmin.app` → 用 `xcrun actool` 编译 `Assets.xcassets`
+得到 `Assets.car` 并合并图标元数据到 `Info.plist` → `zip` 打包 → 生成 `.sha256`。产物：
+
+- `build/ipa/MultiSimAdmin.ipa`
+- `build/ipa/MultiSimAdmin.ipa.sha256`
+
+脚本不需要证书与描述文件，不做任何签名改动；`Assets.car` 缺失时直接失败退出，避免发布没有
+图标的包。
+
+应用图标由脚本光栅化生成，不使用手工位图：
+
+```bash
+cd apps/ios && swift Design/generate_app_icon.swift \
+  Sources/MultiSimAdmin/Resources/Assets.xcassets/AppIcon.appiconset/AppIcon1024.png
+```
+
+图标为扁平构图，不用立体卡与投影：石墨底、黄铜 SIM 面板（切角在左上）、三根底部对齐的递增
+信号条，29pt 尺寸下轮廓仍然可读。`apps/ios/Design/AppIcon.svg` 是同构图参考稿，实际构建使用
+由 `Design/generate_app_icon.swift` 光栅化出的 PNG，面板边长、圆角、切角与信号条间距都可用
+环境变量调整。
+
+## 8. 验证方式
+
+```bash
+cd apps/ios
+swift build
+swift test          # 48 个用例
+xcodebuild -scheme MultiSimAdmin \
+  -destination 'platform=iOS Simulator,id=<UDID>' \
+  -configuration Debug build
+```
+
+单元测试覆盖实例仓储与修订冲突、地址规范化与去重、标签归一化、上游路由白名单、会话隔离、
+连接探测分类、短信解析与分页、设备快照解析、日志仓储与清理、主题模式持久化、时间相对显示、
+版本号契约。界面改动在 iPhone 17 Pro 模拟器上以截图逐页核对浅色与深色两套主题，重点检查控件
+等高、文字不溢出、按钮在深色下不消失。
+
+## 9. 与设计稿的偏离
+
+`docs/superpowers/specs/2026-09-08-ios-native-ipa-design.md` 的以下决策已被实现推翻，该文档
+只作为历史背景保留：
+
+| 原设计 | 当前实现 | 原因 |
+| --- | --- | --- |
+| 底部五 Tab：节点/消息/通知/日志/设置 | 三 Tab：节点/消息/设置 | 应用内通知中心依赖进程常驻，关闭后不可用；日志属于低频排查，收进设置 |
+| 通知通道、规则、投递队列、立即投递 | 未实现 | 同上，移除后不再保留只读残壳 |
+| 实例密码存 iOS Keychain | 沙盒内 `credentials.json` | Keychain 在 TrollStore 环境下读写不稳定 |
+| GRDB + SQLite 控制面库 | 沙盒内 JSON 文件 | 去掉第三方依赖，数据结构与备份语义更直观 |
+| 操作目录、任务、审计、维护、备份 | 未实现 | 高风险写操作与常驻调度不在 iPhone 前台场景内 |
+| 设备模块 13 项（含通话、eSIM、OTA、WiFi Calling、自动化） | 6 个只读模块 + 短信读写 | 上游只保留有稳定读取价值的接口，其余按需在后续版本评估 |
+| 浅灰画布、青绿主按钮 | 深浅双主题、石墨墨色主操作、黄铜点缀 | 0.2.x 视觉重构结论，用户明确排除蓝色 |
+| 实例分组（分组视图、分组编辑器、分组仓储） | 标签归类 + 批量标签 | 分组与标签职责重复，分组作为实体在 0.2.2 移除 |
+
+## 10. 已确认的移除边界
+
+不实现：应用启动后的周期轮询、后台任务与静默推送、Cron 与自动投递、自动备份与自动日志修剪、
+控制台自更新、多用户与远程访问、全局访问密码。
+
+保留：进入前台与下拉刷新触发的一次同步、页面可见时的按需刷新、用户主动发起的登录、检测、
+发送、删除与日志清理。

 ## 目标
 
 把 multi-simadmin 的管理能力改写为独立 iPhone 应用，而不是为现有 Web 服务做一个远程客户端或 WebView 壳。应用面向 iOS 16+ 和 TrollStore 安装环境，构建流程产出未签名 IPA；Apple 证书、开发者账号、TestFlight 和上架签名不在本项目范围内。
