Merge branch 'feat/w80-voice-failed-status-judgment' into android

后端 M57-M59 预告（devdocs/02 第 1255/1260 行我们的答复）：`voice` 键在不再等于
「这是一段能播的声音」。合成降级 / 入站转写失败的行 `status = "failed"`，正文是一句话，
`fallbackReason` 里给出降级原因——按老判据会被画成一个点下去必然播不了的语音气泡。

判据拆成两问，各自落在一处（domain/chat/VoiceMessage.kt）：
- `hasVoice` = `voice` 键存在 —— 「这条**来自**一段声音」；
- `isPlayableVoice` = `status != "failed"` —— 认不出的 status 一律当可播（fail-open：
  多画一枚语音形态最坏是点了播不出来，有既有失败文案兜着；反方向会把真有副本的语音
  静默吞成纯文字，用户再也点不到）；
- `isVoiceMessage` = 两者相与 —— 「画不画语音形态」。

failed 行改画「正文 + 一行灰色小标」：`voiceFallbackNote` 给固定前半句 + 服务端
`fallbackReason` **原样**（不猜闭集、不做映射——取值集合后端尚未定稿；缺席/空白时退化成
固定那一句，不白屏）。新组件 `VoiceFallbackNote` 用 footnote2 +
onSurfaceVariantSummary，与语音形态旁边那几句脚注同一档。

`isContentlessUserMessage` 挂 `hasVoice` 而**不**是 `isVoiceMessage`：failed 行虽没有语音
形态，但有正文和那行小标，同样不是「什么都没有」——判错了屏幕上会多一句假的
「内容没有被传过来」。`messageTimeCarrier` 同理按 `hasVoice` 挑落脚点。

DTO 上补第八个键 `fallbackReason`（只在 failed 时有，`explicitNulls = false` 时不写出），
所以转写成功的行键集仍是原来七个。

验证：`assembleDebug` + `testDebugUnitTest` 全绿，142 个测试文件 / 1766 个用例 / 0 失败
（基线 1755，新增 11 条；VoiceMessageTest 20、VoiceDtoTest 13、WsEventPersistedVoiceTest 7）。

-# Cyrene for Android
-
-昔涟在安卓设备上的载体 —— 随时随地与昔涟对话、操控 IoT 设备、接收实时通知。
-
-## 概述
-
-Cyrene for Android 是 [Cyrene（昔涟）](https://github.com/Cyrene/Cyrene) 项目的官方 Android 客户端。Cyrene 是一个开源的基于 LLM 平台的智能体，提供多人格对话、IoT 设备操控、记忆管理、自动化规则、知识库、语音交互等功能。
-
-Android 客户端的目标是成为用户的**默认语音助手**，完全替代系统自带的助手（Google Assistant / Bixby 等），同时提供：
-
-- **系统级语音助手** — 注册为 `VoiceInteractionService`，可通过长按 Home / 侧滑呼出
-- **语音唤醒** — 息屏热词唤醒、免提交互（类似 "Hey Google"，使用 "昔涟" 等唤醒词）
-- **随时对话** — 通过文字或语音与昔涟交流
-- **IoT 控制** — 远程操控家中的智能设备
-- **实时通知** — 接收昔涟的主动消息、提醒、IoT 状态变更
-- **后台连接** — 即使 APP 在后台，仍保持通知推送与语音服务就绪
-
-## 开发状态
-
-> **当前阶段**：项目初始化，尚未开始正式开发。
-
-根据主项目的[开发路线图](../docs/dev-plan/00-development-roadmap.md)，Android 客户端计划在 **Phase 5（v1.5 → v2.0）** 开始开发，预计时间窗口为 **2027 Q2-Q3**。
-
-## 技术栈 (规划)
-
-| 层 | 技术 |
-|----|------|
-| 语言 | Kotlin |
-| UI 框架 | Jetpack Compose + Material Design 3 |
-| 架构 | MVVM + Repository |
-| 网络 | OkHttp / Retrofit + WebSocket |
-| 本地存储 | Room (SQLite) + DataStore |
-| 推送 | FCM (Firebase Cloud Messaging) |
-| 语音 | VoiceInteractionService + 热词唤醒 + STT + TTS |
-| 构建 | Gradle (Kotlin DSL) |
-
-## 功能路线图
-
-- [ ] 用户认证与登录
-- [ ] 实时文字对话 (WebSocket)
-- [ ] VoiceInteractionService 注册（替换系统语音助手）
-- [ ] 间接启动悬浮窗（VoiceInteractionSession 全屏覆盖层）
-- [ ] 热词唤醒（息屏 / 亮屏）+ 唤醒词自定义
-- [ ] 语音识别 (STT)
-- [ ] 语音合成 (TTS)
-- [ ] IoT 设备控制面板
-- [ ] 推送通知 (FCM)
-- [ ] 后台连接与通知
-- [ ] 锁屏 / 息屏语音交互
-- [ ] PWA 保底方案 (短期替代)
-
-## 交互模式
-
-APP 有两种界面呈现方式，根据启动来源自动切换：
-
-| 启动方式 | 界面模式 | 说明 |
-|---------|---------|------|
-| 桌面图标 / 最近任务 | **全屏 Activity** | 常规 APP 模式，完整功能入口 |
-| 语音唤醒 / 长按 Home / 侧滑 / 长按电源键 / 耳机按键 | **悬浮窗 (VoiceInteractionSession)** | 全屏覆盖层，半透明背景透出底层 APP，不影响当前任务栈 |
-
-悬浮窗模式的要点：
-- 借助 `VoiceInteractionSession` 系统窗口，不压入 Activity 返回栈
-- 对话结束后窗口收起，用户回到触发前的界面
-- 底层 APP 内容半透明可见（模糊遮罩），让用户保持上下文感知
-- 窗口高度自适应对话内容，类似 Google Assistant 的卡片式覆盖
-
-## 设计规范
-
-- **设计语言**：Material Design 3 (Material You)
-- **主题**：动态配色（Dynamic Color），跟随系统壁纸或手动选择主题色
-- **暗黑模式**：支持 Light / Dark 双主题，跟随系统或手动切换
-- **组件**：全面使用 `androidx.compose.material3` 组件库
-- **图标**：Material Icons + 自定义图标
-- **动效**：遵循 MD3 动效规范（过渡动画、涟漪效果、Shared Elements）
-- **字体**：系统默认字体（Roboto / Google Sans），支持动态字体缩放

-
-## 环境要求
-
-- Android Studio Hedgehog (2023.1.1) 或更高版本
-- Kotlin 2.0+
-- JDK 17+
-- Android SDK (target: 34+, min: 26+)
-
-## 网络配置（中国大陆用户）
-
-Gradle、Google Maven、Maven Central 等服务器在国内访问缓慢或不可达，首次同步前需配置镜像。
-
-### Gradle Wrapper
-
-`gradle/wrapper/gradle-wrapper.properties`：
-
-```properties
-# 将 services.gradle.org 替换为腾讯/阿里镜像
-distributionUrl=https\://mirrors.cloud.tencent.com/gradle/gradle-8.7-bin.zip
-# 或阿里: https\://mirrors.aliyun.com/macports/distfiles/gradle/gradle-8.7-bin.zip
-```
-
-### 仓库镜像
-
-`settings.gradle.kts` 顶部添加：
-
-```kotlin
-pluginManagement {
-    repositories {
-        maven { url = uri("https://mirrors.cloud.tencent.com/gradle/plugins") }
-        maven { url = uri("https://mirrors.tencent.com/nexus/repository/maven-public") }
-        google()
-        mavenCentral()
-        gradlePluginPortal()
-    }
-}
-dependencyResolutionManagement {
-    repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
-    repositories {
-        maven { url = uri("https://mirrors.tencent.com/nexus/repository/maven-public") }
-        google()
-        mavenCentral()
-    }
-}
-```
-
-### Gradle 属性
-
-`gradle.properties`：
-
-```properties
-# HTTP 代理（如使用 Clash/V2Ray，通常不需要）
-# systemProp.http.proxyHost=127.0.0.1
-# systemProp.http.proxyPort=7890
-# systemProp.https.proxyHost=127.0.0.1
-# systemProp.https.proxyPort=7890
-```
-
-### Android SDK Proxy
-
-若 Android SDK Manager 也下载缓慢，可在 Android Studio 中设置：
-**Settings → Appearance & Behavior → System Settings → HTTP Proxy**
-
-配置为 `mirrors.cloud.tencent.com` 或 `mirrors.neusoft.edu.cn`，端口 `80`。
-
-## 快速开始
-
-> 项目尚未包含可构建的源码，以下为后续开发的参考步骤。
-
-1. 用 Android Studio 打开 `android/` 目录
-2. 按上述"网络配置"替换国内镜像
-3. 等待 Gradle 同步完成
-4. 启动主项目后端服务（参考[主项目 README](../README.md)）
-5. 在 `local.properties` 中配置 `baseUrl` 指向 Gateway 地址
-6. 选择模拟器或设备，点击 Run

+     * **每个会话那个 VM 常驻的那一半**（S4）由 [chatSessionSlots] 收：本端最多留
+     * [top.yeij.cyrene.core.session.CHAT_SESSION_SLOT_KEEP] 格，多出来的整格交出去。这一条与

+     * 每次重连现读 ⇒ 登出重登、换账号**不需要**重建本实例。**任何 ViewModel 都不许关它**——

+ * 「她主动说的话 ⇒ 弹系统通知」那条通路的**帧消费点**（W57，**进程级**）。
+ *
+ * ## 为什么必须提到这一层（改前那一档是坏的）
+ * 这条通路的判据与去重一直是对的，错的是**订阅挂在哪**。改前它是 `SessionsViewModel` 里那句
+ * `viewModelScope.launch { socket.events.collect(::onEvent) }`。连接倒是进程级的——划掉 Activity
+ * 之后它照样连着、照样在收帧——但 `viewModelScope` 随 Activity 一起结束，而 `ChatSocket.events`
+ * 是 `replay = 0` 的 `SharedFlow`：**没有订阅者的 `tryEmit` 就是当场丢掉**（它不替将来的订阅者
+ * 留任何东西）。于是「从最近任务把 App 划掉、进程还被前台服务撑着」那一档，她的话进了连接、
+ * 然后没了。
+ *
+ * 本类因此只做一件事：**在进程级订那份帧流**，把 [proactiveFrameOf] 认出的帧交给 [ProactiveNotifier]。
+ * 它不建连接、不关连接、不认识登录态——连接的所有权一个字节都没动，仍然只在登录态那一处表达
+ * （`SessionsViewModel` 的 `LoggedIn → connect()` / `LoggedOut → close()`）。
+ *
+ * ## 为什么没有 start() / stop()
+ * 它的生命周期**就是进程**：`AppContainer` 在 `Application.onCreate` 里构造它，此后一直活着。
+ * 刻意不提供 `stop()` 正是这次要修的那个 bug——**唯一会想到去调 stop 的调用方（某个 ViewModel）
+ * 会随 Activity 一起死**，那等于把这条通路又绑回 Activity 上；留一个可以被忘掉调用的 `start()`
+ * 也只是多一种坏法（忘调 = 通知整个哑掉，且没有任何报错）。
+ *
+ * 它不需要停：帧只有连接活着才可能到，而连接在登出（含令牌失效那条经 `onAuthFailed` 的路径）时
+ * 由登录态关掉。「登出期间收不到帧」这件事由**连接**保证，不靠这里取消订阅。去重账本也**刻意不**
+ * 在这里清：它是 `ProactiveNotifier` 里的进程级账本，而换了账号之后同一条消息再推一次，仍是
+ * 同一个人的同一句话，不该弹第二遍。
+ *
+ * ## 它现在是这条通路上唯一的帧消费点
+ * 改前 `SessionsViewModel` 里那两处转交已经删掉（留两处就等于靠去重去替一次重复消费擦屁股，
+ * 而且「谁在喂通知」会有两个答案）。所以这条订阅一旦死掉，通知就**整个**哑掉——兜底见 [deliver]。
+ *
+ * @param events 进程内唯一那条连接的帧流（`ChatSocket.events`）。
+ * @param notifier 判据 + 去重 + 落地那一处。本类只喂帧，不替它判断任何事（那两个入参是它自己的

+/**
+ * 「分享到 App」的接收入口（`ACTION_SEND` / `ACTION_SEND_MULTIPLE`）。
+ *
+ * ## 它为什么是一个进程级单例
+ * 分享进来时可能还没登录、ChatScreen 甚至还没被组合出来，而登录之后消费它的又是**另一个**
+ * Compose 实例。内容因此必须待在一个不属于任何 UI / ViewModel 的地方——见
+ * [PendingShareHolder]。不塞进 `AppContainer` 是因为那个文件同时被别的并行改动占用，
+ * 这里没有任何依赖需要它：本对象只需要一个 `Context`（读 URI、写 cache）。
+ *
+ * ## 图片为什么在收到的那一刻就落盘
+ * `content://` 的读授权只给到**接收它的那个 Activity / 任务**，登录（可能十几秒、还可能切页）
+ * 之后再去读，拿到的多半是 `SecurityException` / 打不开。所以字节在这里立刻拷进 `cacheDir`，
+ * 之后一律用本端自己的 `file://` 路径——**外部 Uri 只在这个方法里出现一次**。文件（非图片）同理。
+ *
+ * ## 分流：图片还是文件
+ * 逐条 URI 看 `ContentResolver.getType`（判定见 [top.yeij.cyrene.domain.share.classifySharedStream]）：
+ * MIME 以 `image/` 开头走既有图片路，**其余一律走文档路**。此前一律当图片拷、当图片解码，
+ * 一份 `.md` 因此只有两种结局——「图片处理失败」或者被当成一张读不出来的图。
+ *
+ * ⚠️ **Manifest 刻意不声明全通配或文本通配 MIME**：后端**明令拒绝** `text/html` / SVG / XML /
+ * 压缩包 / 脚本，放宽声明会造出一堆「点进去必然失败」的入口。所以这里能接到的**文件**只有
+ * 系统按 `text/plain` 投过来那些（`.txt` / `.md` / `.log` 这类文件管理器确实会报 `text/plain`）；
+ * 报成 `text/markdown` 之类的分享**根本不会**出现在 Cyrene 的分享菜单里。
+ *
+ * ⚠️ **provider 不报 MIME（`getType` 回 null）时按文档路走**，这是刻意的：本端不猜类型，
+ * 猜错等于替用户把一个合规文件变成一次失败；代价是「图片但 provider 没报 MIME」会落到文档路、
+ * 被服务端按 `415` 拒（有如实文案）。画廊 / 相机 / MediaStore 都会报图片那一类，风险面很小。
+ *
+ * ## 四个 extra 为什么都读「原始值」
+ * `EXTRA_TEXT` / `EXTRA_SUBJECT` / `EXTRA_TITLE` / `EXTRA_STREAM` 一律用 [Intent.rawExtra] 取原始值，
+ * 再由本文件按**形态**分派（[shareStreamExtrasOf] / [shareTextExtrasOf]）。两个理由：逐类型的
+ * `getXxxExtra` 遇到别的形态只会往 logcat 打一句 `ClassCastException` 再把值扔掉（那正是「分享点下去
+ * 什么都没发生」的来处），而本端还要知道「这个 extra 里**到底有没有躺着值**」——那件事纯函数看不到，
+ * 只能由这里如实报进去（两个 `present` 参数）。
+ *
+ * ⚠️ **正文的回落链起点也在这里**：`EXTRA_TEXT` 读不出东西时，`EXTRA_SUBJECT` → `EXTRA_TITLE` 依次
+ * 顶上（[ShareRules.extract]），来源记进 `SharedContent.textSource`。三个都空 / 都读不出来时，这一次
+ * 分享照样要往下走（走「读不进来」那条如实告知），**绝不静默**。
+ *
+ * ## 清理
+ * 缓存副本只对**产生它的那个进程**有意义（持有者在内存里，进程没了就没人认领），所以
+ * 进程启动时整目录删一次（[reset]）。运行期间不做细粒度回收：那些文件在发送失败被回滚到
+ * 输入框之后**仍然要用**（用户可能过一会儿才点发送），提前删掉就会让预览变空图。
+ * 目录因此以「一次进程生命周期内的分享份数」为界（图片 4 + 文件 5，另加 [stageTextAsDocument]
+ * 为超长正文落下的那一份 `.txt`），另有系统的 cache 回收兜底。

+ *
+ * ## 它抛不抛异常（核对过 AOSP 源码，`sources/android-36.1/android/os/BaseBundle.java`）
+ * - **类型不符不抛**：`Bundle.getCharSequence` 自己 `catch` 了 `ClassCastException`（`unparcel()` 之后

+ *   `intent.getCharSequenceExtra(...)` 不会因为「值不是 CharSequence」把 App 打崩，它只是**读不到**。
+ *   那一档在这里落成 [present] 为真、[text] 为 `null`：既不崩、也不再静默。
+ * - **畸形 bundle 会抛**：它内部的 `unparcel()` 在别的进程给的 bundle 解析不出来时抛

+ * ——本函数被调用就意味着「这一次确实该弹，且这条消息的号已经定好了」，它只负责把号用在通知上。

+ * ## 为什么 id 是入参而不是这里恒定一个
+ * 同 id 的 `notify` 是**替换**：恒用一个号就等于「后来的覆盖先来的」——她连说几句，用户只看到
+ * 最后一句。入参那个号由 [proactiveNotificationId] 按消息派生（输入就是去重键），于是同一句
+ * 无论到几次都落在同一条通知上，而不同的句子各占一条。
+ *
+ * ## 免打扰只换渠道，别的一个字节都不动
+ * [quiet] 为真时整条通知除了「发去哪条渠道 / 7.x 的优先级」以外**逐字节不变**：同一个标题、同一
+ * 段正文、同一个通知号、同一次点击行为。用户要的是「别在我正做事的时候盖住屏幕」，不是「别让我
+ * 知道」——所以什么都不该少，只是她的话安静地躺在通知栏里。
+ *
+ * ## 没授通知权限时什么都不做
+ * `minSdk 33` ⇒ `POST_NOTIFICATIONS` 恒是运行时权限，而系统在未授权时**静默丢弃**通知。与其发一条
+ * 必然无声无息的东西，不如在这里就收手（判据复用保活那处 [notificationsAllowed]，全 App 只有
+ * 一份「授没授」的口径）。用户之后在设置页授权、或直接开通了保活那个开关，下一句话就能弹出来
+ * ——本函数每次都**现读**权限，不缓存。
+ *
+ * ## 小图标用的是平台资源
+ * 工程里没有为通知准备单色小图标（`@mipmap/ic_launcher` 是彩色的，拿它当通知小图标在通知栏上
+ * 会显示成一块白斑）。所以用平台自带的 `stat_notify_chat`——与保活那条用 `stat_notify_sync` 是
+ * 同一个做法。要换成本应用的图标时，只需换下面这一行。
+ *
+ * @param notificationId 这条消息的通知 id，同时也是它点击用的 request code（两者必须一起动：
+ *   只换 id 不换 request code，点后到的那条通知会串到先到那条的 `PendingIntent` 上）。
+ * @param quiet 「免打扰」开关**当下的值**：`true` ⇒ 发到 [QUIET_PROACTIVE_CHANNEL_ID]（有提示音、
+ *   不弹横幅）；`false` ⇒ 发到 [PROACTIVE_CHANNEL_ID]（弹横幅）。**刻意不给默认值**：调用方忘写
+ *   这一位时症状是「开关按了没反应」，那种坏法没有任何报错——让编译器拦住它。

+ * 一条 proactive 消息对应的**通知 id（同时也是它点击用的 request code）**——纯函数，由去重键
+ * [proactiveNotifyKey] 的输出派生。这就是「一事一条」的全部落地形状（W54A）。
+ *
+ * ## 为什么必须与去重键同源
+ * 改前所有她的话共用一个固定 id，而 `notify` 遇同 id 是**替换**：她连说几句，用户只看到最后
+ * 一句，前面那几句在他拿起手机之前就已经没了。按消息派生要回答的第一个问题是「凭什么是同一条」
+ * ——那正是 [proactiveNotifyKey] 已经回答过的（实时帧与落库帧共用它）。**两处口径必须永远同源**：
+ * 去重说「这是同一条」、派生说「这是同一条 ⇒ 同一个号」；分成两套，就会出现「认得出是同一条、
+ * 却排出两条 id」的形状漂移。
+ *
+ * ## 它会撞号，后果如实说
+ * `String.hashCode()` 只有 32 位，再折进 [PROACTIVE_NOTIFICATION_ID_SPAN] 这一段 ⇒ **不同消息
+ * 派生出同一个 id 是会发生的**（约 2×10⁹ 的空间，按生日问题算，通知栏里装几十条时概率可忽略）。
+ * 撞上的后果与改前**一模一样**：后来那条替换先来那条，用户少看见一条提醒。这是刻意接受的那一侧
+ * ——通知只是「她找你了」这一下，她的话本身在主会话里一条不少；反过来要绝对不撞，就得在服务端
+ * 唯一号之外再维护一套映射并持久化它，代价比「极少数情况下少一条提醒」大得多。
+ *
+ * ## 两个坑都在这里堵上
+ * 1. **号必须为正**：通知 id 是一个有符号 `int`，而这个命名空间里正数是纪律（本仓保活那条常驻通知
+ *    是 1；平台对前台服务的 id 更直接写明「must not be 0」）。而 `hashCode()` 可以是负的、甚至
+ *    正好是 `Int.MIN_VALUE`——后者连 `abs` 都兜不住（在 int 域里 `abs(Int.MIN_VALUE)` 仍是它自己）。
+ *    所以这里**先展宽到 `Long` 再取绝对值**：`Int.MIN_VALUE.toLong()` = 2147483648，取绝对值是安全
+ *    的，再折进 [PROACTIVE_NOTIFICATION_ID_SPAN] 后落在正区间。
+ * 2. **不撞既有 id**：见 [PROACTIVE_NOTIFICATION_ID_FLOOR]。

+ * 只回结论，账本与时钟都由调用方喂）——所以它在 JVM 上可以穷举。
+ *
+ * @param key 槽位的稳定标识（`账号指纹|会话 id`）。它就是**结论的载体**：判据只把它原样列出来，
+ *   「拿这个 key 去哪里找槽位」是调用方的事。
+ * @param sessionId 会话 id。**它和 [key] 不是同一件事**：key 里还带着账号指纹（换账号之后同一个
+ *   会话 id 是另一格），而这一位只回答一个问题——**它是不是主会话**（主会话永不回收，见
+ *   [chatSessionEvictions] 第 1 条）。两样都留着是刻意的：把「主会话」这件事换个说法搬出判据，
+ *   它就再也钉不住了（那是本任务的红线之一）。
+ * @param lastUsedAt **最后一次成为当前会话**的时刻（毫秒）。「最近」的口径就是它，理由见
+ *   [chatSessionEvictions]。`0` = 建出来还没打开过（组合被丢弃时留下的空槽位）。
+ * @param holdsUnsentWork 这一格里还有**本端唯一一份**的内容（没发出去的草稿 / 没上路的发送）。
+ *   它必须一路传到这里，是因为「回收」是一条**回不来**的动作：判据要在动手之前就能拦下

+/**
+ * 这一刻该交出去哪几格（**纯函数**，[ChatSessionSlots] 与测试共用）。返回**要回收的槽位 key**，
+ * 最该走的在最前（最旧的最先）；没有要回收的就返回空表。
+ *
+ * ## 「最近」的口径：最后一次**成为当前会话**的时刻
+ * 三选一里选的它，理由是另外两个都答不对这个问题：
+ * - 「最后一次收到这个会话的帧」**不是用户的活动**：共享连接上别的会话的帧一直在来（服务端不按
+ *   会话订阅），一条后台广播就能把一个用户根本没再打开过的会话顶成「最近」。
+ * - 「最后一次有新消息」同理，而且是**别人**的活动（她在次级会话里说一句，本端就要为它留一格）。
+ * - 「最后一次成为当前会话」才是「用户切回去时希望看到什么」这件事本身：槽位存在的意义就是
+ *   那一屏不用重新加载，而**用户看得见哪个会话**只有这一个时刻能表达。
+ *
+ * 它由 `ChatScreen` 在**组合到某个会话时**写入（那正是「它成了当前会话」这一刻），所以判据这边
+ * 只需要比大小，不需要任何时钟：谁的时刻新，谁就留下。同一毫秒并列时按**账本里的先后**退回
+ * （[usages] 的顺序 = 槽位被建出来的顺序，见 [ChatSessionSlots]），也就是「谁先建谁先走」。
+ *
+ * ## 判据与优先级（自上而下，先命中先返回）
+ * 1. **主会话永不回收**：它是抽屉与主流程的锚——用户随时会退回它，而它那一格正是「一进 App
+ *    就有东西看」的来处。这一条**不看** `keep`，也不占「最近」的名额：主会话就是主会话，
+ *    不看它多久没被打开过。
+ * 2. **屏幕上那一格永不回收**（`key == [currentKey]`）：它的 VM 一死，屏幕上那一段就再也不会更新
+ *    （帧收不到、`viewModelScope` 已经取消 ⇒ 连发送都会静默不发），要等下一次重组才会自己修回来
+ *    —— 那是「回收」绝不能带来的一种状态。这一条与主会话同属「按身份豁免」，与时刻无关
+ *    （[currentKey] 那一格通常本来就是最新的，但不靠这件事成立）。
+ * 3. **还有没交代完的事的槽位不回收**（[ChatSessionUsage.holdsUnsentWork]）：那些内容只在本端
+ *    这一份（草稿、排队等连接的发送），回收掉就**回不来**了。这一条压过 `keep` 的语义——
+ *    它宁可让本端多留一格，也不做一件不可逆的事。
+ * 4. 其余按 [ChatSessionUsage.lastUsedAt] 从新到旧留 `keep` 格，**连上面三条占住的一起算**：
+ *    `keep` 是「本端同时保留几格」这个内存目标，所以被豁免的那些**占名额**——不然「最多 3 格」
+ *    在豁免生效时会变成 3 + 豁免数，那个数就没有上限了。（真实使用里豁免的那些几乎总是
+ *    「刚刚还在用的」，本来就在最近 3 个里，这条只在极端情况下才真的挤掉谁。）
+ *
+ * 判据里除了这些入参什么都不看，才能穷举、才能在 JVM 上单测（先例：`ui.chat.reconnectPull`、
+ * `ui.sessions.silentRefreshStep`）。
+ *
+ * ## ⚠️ 它**只**回答「交出去哪几格」
+ * 「交出去」具体是什么动作（清掉那份 `ViewModelStore`、于是这一格的 VM 随 `onCleared` 一起走）
+ * 是调用方的事，而且**必须**是那份 store 自己的 `clear()`：连接是全 App 共享的那一条，它的生死
+ * 只由登录态表达（主人是 `SessionsViewModel`），回收一格**绝不能**碰它——回收一格的状态与
+ * 「别人的流、别人的未读」是两件事，这条判据里连一个字节的连接概念都没有。
+ *
+ * @param usages 账本里的全部槽位（顺序有意义，见「同一毫秒并列」那一句）。
+ * @param mainSessionId 主会话的 id（由装配处注入，判据不认识那个常量本身）。
+ * @param currentKey **此刻屏幕上**那一格的 key（[ChatSessionSlots] 刚记完账的那一格）。
+ * @param keep 本端**同时**保留几格（含主会话、屏幕上那一格与「还有没交代完的事」的那些），

+/**
+ * 本端留着的**会话槽位**（`账号指纹|会话 id` → 那一格的聊天状态）。S4 的解药。
+ *
+ * ## 它回答的是哪一个问题
+ * `ChatViewModel` 是**按会话**建的（`sessionId` 是构造参数），于是「切走 / 删会话都不回收」意味着
+ * 访问过 N 个会话就常驻 N 份消息列表（含内联 base64 图片）、N 份对共享连接的订阅、以及**每次重连
+ * 各自一轮** `after` 补拉。这里就是那个「N」的闸门：**一格一个 `ViewModelStore`**，超出的按
+ * [chatSessionEvictions] 的结论交出整格。
+ *
+ * ## 为什么一格一个 `ViewModelStore`（而不是给 key 加一代号）
+ * 回收的本体动作是「让那一格的 VM 真正死掉」：`ViewModelStore.clear()` 会走 `ViewModel.onCleared()`
+ * 并取消 `viewModelScope`——于是**订阅、补拉、正在飞的那些请求一起停下**。此前每一格都塞在
+ * Activity 级那个 store 里，而它**只有整体 `clear()`**，没有「按 key 交出一格」的入口：那种情况下
+ * 只能让 key 换一代、把旧实例**留在 store 里**（它照样活着、照样收帧——那正是 S4 的另一半没修掉
+ * 的样子）。一格一份 store 之后，`clear()` 的粒度就正好是「这一格」。
+ *
+ * ## 回收**不碰**共享连接
+ * 连接是全 App 唯一的那一条（`AppContainer.chatSocket`），它的生死只由登录态表达
+ * （主人是 `SessionsViewModel`）。本类碰的只有「自己那一格的 store」：掐掉的是这一格的订阅，
+ * 别的会话的流、别的会话的未读、以及那条连接本身一个字节都不动。
+ *
+ * ## 谁碰它、什么时候（全部在主线程上）
+ * - **`ChatScreen`**：组合到某个会话时 [slotFor] 取（或建）槽位——VM 必须有地方建，而槽位就是
+ *   那一格的存放处，所以这一步没法挪到组合之后；组合完成之后 [onOpened] 记账 + 回收。
+ * - **`SessionsViewModel`**：本端**唯一**的删除入口，删成功后 [reclaim]（那一格跟着会话一起走）；
+ *   登出 / 换账号时 [clear]（与快照 / 已读游标 / [GoneSessions] 同一档：换代之后本端什么都不知道）。
+ * - 三者都在主线程上（组合、`viewModelScope` 的默认派发器），所以账本本身不加锁——它的每一个
+ *   读写点都在同一个线程上。
+ *
+ * ## 为什么不持久化
+ * 槽位里装的是**进程内存里的状态**（消息列表、草稿、流式缓冲），它没有可以落盘的形式，而它的
+ * 内容全部另有来源（服务端的 `GET /messages` 那一页 + 服务端的幂等键）。重启之后本端重新拉，
+ * 与 [GoneSessions] 「不持久化」是同一个理由。
