iOS 计划完成：流式发送 / 后台续传 / APNs / Share Extension / 控制中心控件 + 真机分发预备

- 发送端流式（R-iOS-4）：新增 FileSource 抽象（web/src/features/transfer/source.ts），iOS 经 HTTP Range 惰性拉取（原生 WKURLSchemeHandler 认 Range 头 seek 回 206），整文件不进 WebView 内存；web/桌面经 fileSource 包装字节不变。p2p/relay/transfer 改吃 FileSource
- 后台续传：iOS 26 BGContinuedProcessingTask（BackgroundTaskManager + AppDelegate 注册 + BGTaskSchedulerPermittedIdentifiers），引擎传输进度驱动系统进度 UI
- APNs：后端 internal/apns（ES256 .p8 JWT + HTTP/2，仿 internal/push）+ push_subscriptions.platform 列 + POST /api/push/apns/register + transfer/message 未投递分支分流；原生 PushRegistry 授权 + 设备令牌经引擎桥 registerPush 上报；aps-environment + remote-notification 后台模式
- Share Extension：CDropShare appex 抓文件 → App Group 收件箱 → cdrop://share 深链唤主程序选设备发送（只交接、不跑引擎）
- 控制中心剪贴板两控件：CDropWidgets widgetkit appex（ControlWidget + AppIntent + 纯原生 ClipboardClient REST）；用专用 broker 设备会话（主程序经引擎 provisionWidgetSession 代铸独立 device_id 会话存 App Group，控件自刷不与引擎抢 refresh 轮换）
- 真机分发预备：committed 签名改 ad-hoc 使模拟器 entitlement 生效；真机手动签名 scaffold（Signing.xcconfig 仅 device SDK 套 Manual + gitignore 的 Local.xcconfig 填 Team/profile）+ just ios-device / ios-devices 全 CLI 装机；包名改 net.commilitia.Commilitia-Drop（含 .share/.widgets，BG task 前缀同改）；REALDEVICE.md 重写为门户 + CLI 装机手册
- I18n.swift 移 Shared/ 供三 target 共用；i18n 加 ios.bg/share/control.* 键
- ultracode 多 agent 审查修复（0 HIGH，2 MED + 7 LOW）：分享 send 后留收件箱致重发→move 私有暂存；WidgetSession 锁屏文件保护→UntilFirstUserAuthentication；outgoing/安全作用域登出释放；控件 device_id 登出清理；并发控件 refresh CAS-before-clear；APNs 读 reason + prune bad token + bust 过期 JWT；APNSEnv 大小写归一；Share-ext completeRequest 挪进 open 回调

-# cdrop iOS 真机自测手册
+# cdrop iOS 真机分发手册
 
-账号到位即可照做。模拟器构建不需签名，已全程 compile + 跑通；**真机**要付费 ADP + 签名 + 实体 iPhone，下面是 turnkey 步骤 + 只能真机验的清单。
+把 cdrop 装到你自己的 iPhone（开发签名，1 年 profile）。代码侧全部就绪并经模拟器验证；真机只差**账号 + 门户 + 签名**这一层。本手册走**手动签名 + 全 CLI**路线——门户你手动建（一次），构建装机一条命令，**全程不碰 Xcode GUI**。
+
+## 包名与标识（门户里要用的）
+
+| 项 | 值 |
+|---|---|
+| 主 app Bundle ID | `net.commilitia.Commilitia-Drop` |
+| Share Extension | `net.commilitia.Commilitia-Drop.share` |
+| 控件扩展 | `net.commilitia.Commilitia-Drop.widgets` |
+| App Group | `group.net.commilitia.cdrop`（与包名相互独立，刻意不同名） |
+| APNs topic（服务端 `CDROP_APNS_TOPIC`） | `net.commilitia.Commilitia-Drop` |
 
 ## 前置
 - 付费 Apple Developer Program（$99/年）。
-- 一台 iPhone（iOS 26），Mac 装 Xcode 26。
+- 一台 iPhone（iOS 26）+ Mac（Xcode 26 命令行工具）。
-- 已登录的 cdrop（网页 / 桌面）一个——用来扫码批准本机登录。
+- 一个已登录的 cdrop（网页 / 桌面）——用来扫码批准本机登录。
 
-## 出工程 + 签名
+---
-1. `cd ios/CDrop && xcodegen generate`（从 `project.yml` 生成 `CDrop.xcodeproj`）。
-2. Xcode 打开 `CDrop.xcodeproj` → 选 `CDrop` target → Signing & Capabilities：
-   - **Team** 选你的 ADP 团队；**Bundle Identifier** 用你账号下可注册的（默认 `net.commilitia.cdrop`，前缀按你的改）。
-   - 让 Xcode 自动管理签名（Automatically manage signing）。
-3. 连 iPhone、信任、选作运行目标 → Run。
-   - `project.yml` 里 `CODE_SIGNING_ALLOWED: NO` 是给模拟器的；Xcode 真机自动签名会覆盖它，无需手改。
 
-## 引擎可达性（让传输真能连）
+## A. 门户操作（developer.apple.com/account，一次性）
-- 真机上引擎 WebView 默认加载 `https://drop.commilitia.net/engine.html`——**该文件要先随 web 部署到 prod**（`vite build` 已产出 `dist/engine.html`，随正常 web 发布上线）。
-- 或本机联调：设环境变量 `CDROP_ENGINE_URL` 指向可达引擎、`CDROP_API_BASE` 指向后端。
 
-## 后续功能要补的 capability（按需，各自要在 Developer Portal 配 App ID）
+> 入口：登录后左侧 **Certificates, Identifiers & Profiles**（证书 / 标识符 / 描述文件总枢纽）——A1–A5 都在这里面；A6 在 **Keys**；Team ID 在 **Membership details**（10 位，记下）。
-- **App Groups**（`group.net.commilitia.cdrop`）：Share Extension / 控制中心控件与主 app 共享数据。
-- **Push Notifications** + APNs `.p8`：传输事件推送。
-- **Keychain Sharing**：跨 app / 扩展共享登录态。
-- **Associated Domains**：若改用 OIDC Universal Link 回调（扫码登录则不需要）。
 
-## 只能真机验的清单
+1. **证书**（Apple Development）：本机「钥匙串访问」可能已有（「我的证书」分类里看）。没有就：钥匙串访问菜单 → 证书助理 → 从证书颁发机构请求证书 → 存到磁盘 → 门户 **Certificates** → ＋ → Apple Development → 传 CSR → 下载 `.cer` 双击安装。
-- [ ] 液态玻璃在真机渲染（含陀螺仪高光 / 动效）。
+2. **App IDs ×3**（**Identifiers** → ＋ → App IDs → App，Bundle ID 选 **Explicit**）：
-- [ ] 扫码登录：本机显码 → 用已登录 cdrop 扫码批准 → app 进入主界面。
+   - `net.commilitia.Commilitia-Drop` — 勾 **App Groups** + **Push Notifications**
-- [ ] **本地网络权限**：首次同内网传输弹 `NSLocalNetworkUsageDescription` 提示；授予后 ICE 收到 host 候选（R-iOS-6）；拒绝则回退中继仍可传。
+   - `net.commilitia.Commilitia-Drop.share` — 勾 **App Groups**
-- [ ] 发送：选文件 → 选设备 → 对端收到。
+   - `net.commilitia.Commilitia-Drop.widgets` — 勾 **App Groups**
-- [ ] 接收：对端发来 → 落到 Files（沙盒 Documents）。
+3. **App Group**：**Identifiers** 页类型筛选切到 **App Groups** → ＋ → `group.net.commilitia.cdrop`。再回上面 3 个 App ID 各自的 App Groups 能力里 **Edit/Configure** 关联它（三个都要）。
-- [ ] 后台：传输中切后台 → `BGContinuedProcessingTask` 续传行为（R-iOS-1 / R-iOS-3）。
+4. **设备**：**Devices** → ＋ → 填 UDID（插上手机后 `just ios-devices` 读）。
-- [ ] 大文件：发送侧内存（当前整文件入内存，大文件需转分块流式 = R-iOS-4）。
+5. **描述文件 ×3**（**Profiles** → ＋ → **iOS App Development**，非 Distribution）：每个选对应 App ID + 证书 + 设备，命名清楚（建议 `CDrop Dev` / `CDrop Share Dev` / `CDrop Widgets Dev`）→ 下载 → 双击安装。
+6. **APNs Auth Key**（**Keys** → ＋ → 勾 Apple Push Notifications service）：下载 `AuthKey_XXXXX.p8`（仅一次），记 **Key ID** + **Issuer ID**（服务端发推送用，见 D）。这把 `.p8` 与 A1 的证书是两码事。
 
-## 已知 TODO（真机阶段一并收）
+> 常见坑：Bundle ID 选 **Explicit** 不是 Wildcard；App Group 务必 3 个 App ID 都关联；Profile 选 **Development** 不要 Distribution。
-- 会话 Keychain 持久化 + 自动续期（当前会话在内存、重启需重扫；续期端点 `/api/auth/refresh` 已可用，靠 cookie）。
+
-- 发送侧大文件分块流式（R-iOS-4）。
+---
-- 剪贴板 App Intent + 控制中心控件（决策 C）、Share Extension——需上面的 capability + 账号才能跑。
+
+## B. 本地签名配置（gitignore，填一次）
+
+在 `ios/CDrop/Local.xcconfig` 写入（此文件已 gitignore，公开仓库不留你的账号标识）：
+
+```
+CDROP_TEAM_ID = ABCDE12345
+CDROP_PROFILE_APP = CDrop Dev
+CDROP_PROFILE_SHARE = CDrop Share Dev
+CDROP_PROFILE_WIDGETS = CDrop Widgets Dev
+```
+
+- `CDROP_TEAM_ID`＝A0 的 Team ID；三个 `CDROP_PROFILE_*`＝A5 你起的 profile 名（**名字**，不是文件路径）。
+- 机制：`Signing.xcconfig`（已提交）仅对 **device SDK（iphoneos）** 套用手动签名 + 这些值；**模拟器**仍走 `project.yml` 的 ad-hoc（`CODE_SIGN_IDENTITY = "-"`），故缺 `Local.xcconfig` 也不影响模拟器构建。
+
+---
+
+## C. 构建装机（全 CLI）
+
+```sh
+just ios-devices                 # 手机插 USB，读 UDID（填进门户 A4 + 下行）
+just ios-device <你的设备UDID>   # 真机构建（手动签名）+ devicectl 装机
+```
+
+- `just ios-device` ＝ `xcodegen generate` → `xcodebuild`（device，手动签名走 `Local.xcconfig`）→ `xcrun devicectl device install app`。无 Xcode GUI。
+- 首次装机后，iPhone 上首启该开发者 app 即可直接跑（付费 ADP 开发证书，无需手动「信任开发者」）。
+
+---
+
+## D. 服务端前置
+
+1. **引擎可达**：真机上引擎 WebView 加载 `https://drop.commilitia.net/engine.html`——**该文件随 cdrop 二进制部署到 prod**（`//go:embed` 进 binary，`just docker-image` 含最新 `dist`）。手机要用，prod 须是含本轮改动的最新部署。
+2. **APNs 真发**：把 A6 的 `.p8` 放到服务器，给后端容器配 `CDROP_APNS_KEY_PATH` / `CDROP_APNS_KEY_ID` / `CDROP_APNS_TEAM_ID` / `CDROP_APNS_TOPIC=net.commilitia.Commilitia-Drop` / `CDROP_APNS_ENV`（Xcode 开发构建的 device token 属 **sandbox**，故联调填 `sandbox`）。缺配置则推送惰性关闭，其余功能照常。
+3. 本机联调可选：环境变量 `CDROP_ENGINE_URL` 指向可达引擎。
+
+---
+
+## E. 只能真机验的清单
+
+代码已实现，下列是真机才能验的点：
+
+- [ ] 液态玻璃真机渲染（陀螺仪高光 / 动效）。
+- [ ] 扫码登录：本机显码 → 已登录 cdrop 扫码批准 → 进主界面（强制 full/persist）。
+- [ ] **本地网络权限 + 同内网直连**（R-iOS-6）：首次同内网传输弹 `NSLocalNetworkUsageDescription`；授予后 ICE 收 host 候选、走真直连；拒绝则回退中继仍可传。
+- [ ] 发送 / 接收：选文件 → 选设备 → 对端收到；对端发来落 Files（Documents）。
+- [ ] **大文件流式发送**（R-iOS-4 已实现）：发大文件，WebView 内存应有界（按 Range 块拉取，不整文件入内存）。
+- [ ] **后台续传**（R-iOS-1 / R-iOS-3）：传输中切后台 → `BGContinuedProcessingTask` 系统进度 UI；验 WKWebView JS 是否随之保活（不保活则退化为回前台续传，可接受）。
+- [ ] **APNs 推送**：离线设备收「收到文件」通知（需 D2 的 `.p8`）。
+- [ ] **Share Extension**：别的 app 分享 → 选 Commilitia Drop → 唤起主 app 选设备发送。
+- [ ] **控制中心剪贴板两控件**：控制中心加「上传 / 拉取剪贴板」控件 → 锁屏 / 解锁态点按 → 云剪贴板读写。

+## 计划主体（I1–I7）：已实现（2026-06-27）
 
-1. **登录会话显示修复**（未做）：iOS 客户端在（web）“登录会话”列表中误显示为“本地账号”，应按 device_type 显示“iOS 客户端”（`deviceType.ios`）。疑似列表按会话 kind（self / 扫码自签）而非设备类型贴标签——需让扫码自签会话也带 device_type 标签呈现。
+传输（含发送端流式 R-iOS-4）/ 设备 + 会话管理 / 强制 full 登录 / 登出 / 传输详情 / 后台续传（BGContinuedProcessingTask）/ APNs（后端 + 原生注册）/ Share Extension / 控制中心剪贴板两控件——全部落地、模拟器验、经 ultracode 审查修讫。详见 `ios/PLAN.md` 里程碑 + `ios/PARITY.md` 漂移日志。
-2. **设备 / session 管理非空壳**（数据侧已做，管理操作未做）：列表数据已由“A”接真实 presence（`DeviceListView` 读 `engine.devices`）。剩余：会话管理操作（查看 / 吊销其他会话等）。
-3. **禁止临时登录**（未做）：iOS app 不应允许 guest / 临时（once）登录；扫码登录应强制 full / persist（“信任此设备”）scope。当前后端 qr 默认 guest、`AuthManager` 也写死 `scope: "guest"`——需 iOS 侧走 full。
-4. **退出登录**（已做）：设置页“账户”区已加登出（destructive），清 Keychain 会话 + 复位引擎 + 回登录页（`SettingsView.logout` → `auth.logout()` + `engine.reset()`）。
-5. **传输详情**（已做）：`TransferDetailView` 按 sessionId 实时查引擎态，展示方向 / 对端 / 状态 / 阶段 / 通道 / 大小 / 进度 / 速度；卡片可点入。剩余可选：ICE 候选明细（`transfer.debug.*` catalog 已有，未接）。
 
-> **A 已完成**：引擎 presence / 传输 → 原生 UI 数据绑定（三屏全替 demo）+ `TransferDetailView` + Keychain 会话持久化 + 登出 + i18n 插值。闭合 #4 / #5 与 #2 数据侧；prod 已部署 `engine.html`（presence 生效）。**剩余择期**：#1（device_type 标签）、#3（强制 full 登录）、#2 会话管理操作、#5 ICE 明细（可选）。全部仍未提交（按用户序：真机测完再 commit）。
+## 早期 5 项（2026-06-24 列）状态
+
+1. **登录会话列表显示**：iOS 设备在（web）「登录会话」列表的标签——broker 迁移后 sessions 已按设备 cache 叠加 type（device-session 铸入 `device_type:"ios"`），**疑已解决，待真会话核**。
+2. 设备 / 会话管理：✅（设备页吊销 + 后端 list/revoke/rename）。
+3. 强制 full 登录：✅（iOS 拒非 full + 后端对非 browser 兜底 full/persist）。
+4. 登出：✅。
+5. 传输详情：✅（`TransferDetailView`；可选 ICE 明细已接）。
+
+## 真机阶段（账号门控，见 REALDEVICE.md）
+
+真机签名跑通 + 同内网直连 / 本地网络权限（R-iOS-6）+ 后台挂起行为（R-iOS-3）+ APNs 真发 + Share Extension / 控件真机交互验证。代码就绪，等付费 ADP + 门户 + 设备。
+
+## 余项（择期）
+
+- 控件「添加控件」库名 + Shortcuts 标题随设备语言（需为 `CDropWidgets` 加 `.xcstrings`；当前简体静态，审查 L7，平台专属可接受）。
+- 发送端 `outgoing` 暂存 + 安全作用域访问按传输完成逐项释放（当前登出统一清，审查 L1 余量）。
