+# Agent Note: User-owned goal pause exposes live activation
+
+Status: implemented

+
+## Problem
+
+The host-pause fix in [Host-initiated goal pause aborts the live turn](2026-09-01-host-goal-pause-aborts-turn.md) stopped the current model turn, but a later human turn could still use `update_goal resume` to lift a durable `paused` goal. The Web strip also read only the durable `goal` projection, so an active-but-disarmed goal and an armed goal rendered identically and offered the same pause action.
+
+## Decision
+
+`ctx.goals.get` is a read-only Remote method. `GoalService` emits `goal/activation-changed` whenever its process-local activation changes, with `{ sessionId, goal: { id, revision, activation } }` or no goal after a clear. The API Remote allowlist forwards that JSON payload to Web clients.
+
+The GoalBar seeds process-local activation from `ctx.remote.goals.get`, applies `goal/activation-changed`, and refreshes on durable revision or session running-state changes. Active goals render `Ongoing Goal` only when armed; active-but-disarmed goals render `Inactive Goal`, expose resume instead of pause, and durable paused goals keep exposing resume. Pause authority remains in the goal domain and human `/goal resume` command, which can still resume every resumable phase.
+
+The `update_goal resume` action rejects a durable paused goal with `GOAL_TOOL_RESUME_PAUSED` before calling the goal service. It still resumes an active-but-disarmed goal after session restore or fork and a blocked goal after human continuation. The model prompt and tool description state that the user owns durable paused resume.
+
+## Alternatives considered
+
+**Store activation in the durable `GoalSnapshot`.** Rejected: activation is process-local by the goal domain contract and must not survive restore or fork.
+
+**Add activation to the persisted session projection.** Rejected: projection state is checkpointed; a cached `armed` value would incorrectly outlive the process that armed it.
+
+**Forward the full scoped `goal/changed` event to clients.** Rejected: its `Agent` payload is not JSON wire data. The dedicated activation event carries only the session id, goal ref, and activation clients need.
+
+**Let the model resume durable paused goals from natural-language turns.** Rejected: a manual pause is a user control, and prompt-only restraint leaves the same turn-level undo available to the model.
+
+## Consequences
+
+The Web can distinguish running, disarmed, and paused goals without persisting activation. A durable paused goal is resumable only through the Web control, `/goal resume`, or another direct goal-service caller; model `update_goal resume` is limited to disarmed-active and blocked goals. The API surface gains one read and one forwarded live event; durable goal change payloads and projection state versions are unchanged. Human cancellation now requires the user-facing resume path as well.
+
+## Testing
+
+Goal unit tests pin the activation event across create, session start, and resume. Tool tests pin rejection of a durable paused goal in a later human turn while restored disarmed-active goals still resume. API Remote tests pin JSON forwarding. Web unit tests pin armed pause versus disarmed resume rendering and event application; the assembled goal-bar browser scenario still pins the armed golden.

+
+## 问题
+
+[宿主发起的 goal 暂停中止当前轮次](2026-09-01-host-goal-pause-aborts-turn.zh.md) 修复了当前模型轮次不停止的问题，但之后的人类轮次仍可通过 `update_goal resume` 解除持久的 `paused` goal。Web 条带也只读取持久的 `goal` 投影，因此 active-but-disarmed 的 goal 与 armed 的 goal 渲染相同，并提供相同的暂停动作。
+
+## 决策
+
+`ctx.goals.get` 现在是一个只读 Remote 方法。`GoalService` 在进程本地 activation 变化时发出 `goal/activation-changed`，载荷为 `{ sessionId, goal: { id, revision, activation } }`，clear 后则不携带 goal。API Remote 允许列表把这份 JSON 载荷转发给 Web 客户端。
+
+GoalBar 通过 `ctx.remote.goals.get` 播种进程本地 activation，应用 `goal/activation-changed`，并在持久 revision 或会话 running 状态变化时重新读取。Active goal 仅在 armed 时渲染 `Ongoing Goal`；active-but-disarmed goal 渲染 `Inactive Goal`，暴露 resume 而不是 pause；持久 paused goal 继续暴露 resume。暂停权威仍属于 goal 领域和人类 `/goal resume` 命令，它们仍可恢复每个可恢复 phase。
+
+`update_goal resume` 会在调用 goal 服务前用 `GOAL_TOOL_RESUME_PAUSED` 拒绝持久 paused goal。它仍会在会话恢复或 fork 后恢复 active-but-disarmed goal，并在人类要求继续时恢复 blocked goal。模型提示词和工具描述说明持久 paused 的恢复由用户独占。
+
+## 考虑过的替代方案
+
+**把 activation 存入持久 `GoalSnapshot`。** 否决：按 goal 领域约定，activation 是进程本地的，绝不能跨恢复或 fork 存活。
+
+**把 activation 加入持久 session projection。** 否决：投影状态会写入检查点；缓存的 `armed` 会在武装它的进程消失后继续错误存在。
+
+**把完整的 scoped `goal/changed` 事件转发给客户端。** 否决：其 `Agent` 载荷不是 JSON wire 数据。专用 activation 事件只携带客户端需要的 session id、goal ref 与 activation。
+
+**允许模型从自然语言轮次恢复持久 paused goal。** 否决：人工暂停是用户控制，仅靠提示词约束仍会把同轮撤销能力留给模型。
+
+## 后果
+
+Web 无需持久化 activation 就能区分运行中、disarmed 与 paused goal。持久 paused goal 只能通过 Web 控件、`/goal resume` 或其他直接调用 goal 服务的调用方恢复；模型 `update_goal resume` 仅限 disarmed-active 与 blocked goal。API 表面新增一个读取和一个转发 live 事件；持久 goal change 载荷与投影 stateVersion 不变。人类取消现在也需要面向用户的恢复路径。
+
+## 测试
+
+Goal 单元测试固定 create、session start 与 resume 过程中的 activation 事件。工具测试固定后续人类轮次中持久 paused goal 的拒绝，同时保留已恢复 disarmed-active goal 的恢复。API Remote 测试固定 JSON 转发。Web 单元测试固定 armed 显示 pause、disarmed 显示 resume 与事件应用；组装的 goal-bar 浏览器场景仍固定 armed golden。完整构建的 Host typecheck 与 client typecheck 通过。

 - Semantic classification of a substantial goal, a request to continue, objective completion, and the same blocking condition remains model judgment. An independent evaluator or completion certificate is deferred.
+- The model cannot resume a durable paused goal; that user-owned path is enforced by the separate [user-owned goal pause decision](../bug-fix/2026-09-03-user-owned-goal-pause-activation.md).
 - These tools mutate goal state but do not schedule goal rounds, classify abnormal driver stops, or cancel an active turn; the same-session driver owns those behaviors.
 - Goal-round authority is dormant unless a separately mounted continuation driver admits goal-sourced user turns; this tool package never manufactures that authority itself.
 - Human slash-command discovery and rendering are owned by the separate [`dsh-command-goal`](../../../../packages/goal/command-goal/README.md) plugin.

 ## Summary
 
-`dsh-tool-goal` gives the model three tools over the persisted goal service: `get_goal` reads the current goal, `create_goal` starts a new one, and `update_goal` edits, pauses, resumes, completes, or blocks it. The model may infer a long-running objective from a direct human request and create a goal; updates must carry the exact id and revision read beforehand. Authority is enforced at execution: create, edit, pause, and resume require a direct human turn on a top-level agent, while complete and blocked also accept the current goal round during automatic continuation. A configured threshold (default 3) bounds how soon an autonomous round may self-report `blocked`. Mount it with `dsh-goal` whenever the model should manage goals itself.

 An autonomous round that successfully reports `complete` or `blocked` also ends the physical turn after that step, and the model receives a closing instruction to write the final message to the user. Direct-human mutations never trigger that stop: the assistant may acknowledge the change and the loop keeps concurrent human steering available.

A durable paused goal fails the `resume` action with `GOAL_TOOL_RESUME_PAUSED`; the user-facing command or Web control owns that transition. Durable fork lineage does not demote a resumed root; live subagent ownership does.
 - **Host attestation of human input.** `{ kind: 'user' }` is assigned by `Agent.followup()` and `steer()` when their caller omits a source, so plugins, schedulers, and other non-human producers must pass their own source rather than inheriting human authority.
 - **System-prompt guidance with the configured threshold.** The package registers one `tool:goal` system-prompt section whose fixed text interpolates `blockedAfterConsecutiveRounds`; the same value is the hard lower bound enforced at execution.
 - **Wrap-up context for terminal rounds.** A successful autonomous `complete` or `blocked` defers a closing `<goal_complete>` or `<goal_blocked>` instruction so the model addresses the user once before the turn ends; direct-human mutations never defer this context.

 ## 概述
 
-`dsh-tool-goal` 为模型提供基于持久 goal 服务的三个工具：`get_goal` 读取当前 goal，`create_goal` 创建新 goal，`update_goal` 编辑、暂停、恢复、完成或阻塞它。模型可以从人类直接请求中推断长期目标并创建 goal；更新必须携带先前读取到的精确 id 与 revision。权限在执行时强制：create、edit、pause 和 resume 要求顶层 agent 的当前轮次中存在人类直接消息；complete 和 blocked 在自动续行期间还接受当前 Goal Round。可配置的阈值（默认 3）约束自主 Round 多快可以自行报告 `blocked`。当模型需要自行管理 goal 时，与 `dsh-goal` 一起挂载它。

After session resume or fork, an active goal is disarmed: when a human asks to continue or resume in any wording or language, use update_goal action resume to rearm it. Do not call update_goal resume for a durable paused goal; the user resumes that state from a user-facing goal control. Mark complete only when the objective is actually achieved. Mark blocked only after the same blocking condition persists for at least 3 consecutive goal rounds, and report that concrete condition in blocked_reason; difficulty, uncertainty, or useful remaining work is not blocked.
 
 Use the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.

After session resume or fork, an active goal is disarmed: when a human asks to continue or resume in any wording or language, use update_goal action resume to rearm it.

 Use the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.

After session resume or fork, an active goal is disarmed: when a human asks to continue or resume in any wording or language, use update_goal action resume to rearm it. Do not call update_goal resume for a durable paused goal; the user resumes that state from a user-facing goal control. Mark complete only when the objective is actually achieved. Mark blocked only after the same blocking condition persists for at least 3 consecutive goal rounds, and report that concrete condition in blocked_reason; difficulty, uncertainty, or useful remaining work is not blocked.
 
 Use the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.

After session resume or fork, an active goal is disarmed: when a human asks to continue or resume in any wording or language, use update_goal action resume to rearm it.

 Use the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.
