 - **`ui-activity` returns to its upstream name `ui-jobs`** and renders one roster: `jobsBySession` rows, expandable exactly when `outputTotal` is present. The two-roster join is deleted.
 - **Foreground workflow loses its live panel deliberately.** `tool-workflow`'s activity mirror is removed; a foreground run surfaces through its recorded run/member lifecycle events only, and the per-line `workflow/phase` / `workflow/log` narration has no observer until workflow gains `run_in_background` and registers a record job. Jobs stay a pure background registry — no `foreground` mode bit, no model-invisible rows, no run-less rows.
 
-## Rejected
+## Alternatives considered
 
 - **A `foreground: true` job mode** to keep the foreground workflow panel: it needs two coupled enforcement points (reported-at-birth and a `job_list` filter) whose divergence double-delivers or leaks rows to the model, for one edge feature replaceable by `run_in_background`.
 - **Serving model reads from the record** (deleting `readOutput`): model reads are producer-formatted (truncation and spill notices, sandbox markers) and consuming; the record is raw, channel-labeled, and non-consuming. Unifying them moves producer-specific formatting into the registry or noise into the observer stream.

 - **`ui-activity` 改回上游名字 `ui-jobs`**，渲染单一名册：`jobsBySession` 行，恰在 `outputTotal` 存在时可展开。双名册 join 被删除。
 - **前台 workflow 有意失去实时面板。** `tool-workflow` 的 activity 镜像被移除；前台 run 只通过已记录的 run/member 生命周期事件呈现，逐行的 `workflow/phase` / `workflow/log` 叙述在 workflow 获得 `run_in_background` 并登记 record job 之前没有观察者。jobs 保持纯后台注册表——没有 `foreground` 模式位、没有模型不可见行、没有无 run 行。
 
-## 已否决
+## 曾考虑的替代方案
 
 - **`foreground: true` job 模式**以保留前台 workflow 面板：它需要两个耦合的执行点（出生即 reported 与 `job_list` 过滤），两者一旦分叉就会双投递或向模型泄漏行，而它换来的只是一个可被 `run_in_background` 替代的边缘特性。
 - **用 record 服务模型读取**（删除 `readOutput`）：模型读取是生产者格式化的（截断与 spill 提示、sandbox 标记）且消耗型；record 是原始、带 channel 标签、非消耗的。统一二者要么把生产者特有格式化搬进注册表，要么把噪声混入观察者流。

 Client adapter 提供 `SessionEventStream`，即绑定到一个普通 Session 或 direct subagent address 的 Gateway `RemoteJournalStream`。它在读取首个 page 前打开 follow，只发布连续的 `replace`、`prepend` 和 `append` 变更，并通过 tail page 修复重连或 seq 缺口。普通 record 覆盖 `[event.seq, event.seq]`，packed row 覆盖 `[event.seq, event.seq + memberCount - 1]`。业务、persistence 或无法恢复的连续性错误会终止 stream，只有物理载体断开才触发自动恢复。`SessionControlStream` 是 Gateway `RemoteSnapshotStream`；每代都以完整的进程本地 baseline 开始，因此重连会替换 queue、jobs 和 projection 状态，而不会把瞬态值当作 durable event。
 
+`SessionJob` 行恰在该 job 声明了观测 record 时携带 `outputTotal`，`session.observeJob` 从绝对字节偏移流式发送该 record——一个 `opened` 锚帧、聚合的 `output` 帧、最后一个终态 `status` 帧——围栏读取者由请求的 session 解析。record 读取是非消耗的：模型侧游标与完成通知状态永远观察不到它们。Client adapter 提供 `ctx.jobOutput`：按 job 引用计数的观测服务，任务列表 UI 渲染其累积视图；同一 job 的观察者共享一条流，重连时从模型游标续读。
+
 Session 对象还承载本地提交回显：`session.beginSubmission` 在调用方序列化与 prompt 之前，同步把一条回显写入 `SessionSnapshot.pendingSubmissions`，会话 UI 因此能在点击提交的当帧显示消息。Session 根据当前运行状态与请求的投递模式推导每条回显的 `transcript`、`queued` 或 `steering` 位置，并在序列化期间保留该位置。prompt 的 `requestId` 是关联标识：Host 把它回显为 durable user source 的 `rpcId`，queue occurrence 也把它投影为 `SessionQueuedItem.rpcId`。回显在观察到其 durable event 或 queue occurrence 后延迟一个动画帧退休，该延迟保证替代内容就绪前回显仍可渲染；带标识的 prompt 失败或被放弃时立即退休，销毁时按 failed 退休；每次退休恰好触发一次注册的 `onRetire` 回调。回显只存在于 Client 内存；刷新与重连只从 durable event 重建会话。

+- **record 保留量有界。** 追加超出运行期上限时丢弃最老的保留块（单个超限块保留其 UTF-8 安全尾部）；低于保留窗口的读取得到 lossy 结果而非错误，结算时裁剪到结算上限。
 - **按所有者分层，一个进程级注册表。** 控制器、完成监听器与变更观察者归档到注册方所在的 scope（`ScopedLayers`），读取把全局层与所有者的 scope 链求并集——因此某个 preset 的任务控制绝不会为自身组合未加载任何控制器的 agent 保持 `start()` 可用，一次结算也只会抵达其所有者所属组合注册的监听器。
 - **启动前先预检。** `start()` 在调用生产方之前检查控制器服务、spec 有效性、仍存活的所有权与容量，因此拒绝不会留下 job id 或执行资源；注册一旦提交，后续不再有可失败步骤。
 - **结算首次优先，完成最后。** 最早的终止结果只记录一次，释放等待方，并只通知监听器一次，各监听器故障单独隔离；完成在记录提交且可见集变更发布之后才宣布，因为报告方可能同步开启一个模型轮次。

 ## 概述
 
-`dsh-tool-pwsh` 为 agent 提供 `pwsh` 工具，通过已挂载的 shell 执行器运行 PowerShell 命令——它是 `dsh-tool-bash` 的 Windows 对应物，逐调用镜像。每次调用都运行在全新 pwsh 进程中，因此状态不会保留；`run_in_background` 把长时间运行的命令变成后台任务。命令是 PowerShell 方言：原生 `C:\...` 路径与 `$env:NAME` 变量，不做方言翻译。每次调用都运行在受管 `DSH_*` 环境中；在沙箱执行器下，工具会教授并执行 Windows 特有的语言模式与命名管道约定。请与 `dsh-pwsh-local` 等 PowerShell 执行器以及 `dsh-shell-env` 插件一起挂载。加载了可选的 `ctx.activities` 注册表时，已提交的后台运行还会被尽力镜像为按 `activityPollMs`（默认 150）泵送的 `pwsh` activity，与 `dsh-tool-bash` 完全一致。

 对于根 transport 执行（`exec.parent` 缺省），工具会用四个 log-only 事件把运行投影到调用 Agent 的 Session：`start()` 返回后写 run-start，只记录 `run.id` 匹配的成员开始与结束，并且只在结果可用且 dispose 完全停稳后写 run-end。嵌套 transport 调用照常执行，但不写任何记录。任一次 Session append 首次失败后，本运行会停止后续记录并只告警一次，留下空记录或合法连续前缀，同时不改变工具结果和清理。包 invariant 会在冷加载与实时追加时拒绝重复 start、未配对成员、仍有开放成员的终点与 run-end 后更新，同时允许缺失终态后缀的连续前缀。
 
-在持久记录之外，每个被记录的顶层运行还会被尽力镜像进可选的 `ctx.activities` 注册表，作为一个 `workflow` activity：原本无人消费的 `workflow/phase` 与 `workflow/log` 事件加上成员生命周期行流入其中，使 Web 客户端看到会话日志刻意不逐行携带的实时叙述。没有注册表、或镜像出现任何失败时，运行本身不受影响。
+引擎的 `workflow/phase` 与 `workflow/log` 事件在本工具没有逐行的持久或观察面：会话日志刻意只记录 run 与成员生命周期，Web transcript 由这些记录派生。
