fix: avoid blocking on the task that just started

When an assistant turn emits both confirm and start_next, confirm may
already start the newly queued proposal. The later start_next then sees
the just-started task as an active blocker and appends a false running-task correction. Suppress that redundant start_next correction when confirm in the same turn already started the current user proposal. Also tighten the worker bootstrap wording to run confirmed low-risk work continuously until a real decision point.

+description: gori-agent Bot 的代码发布、实例配置、Assistant/Worker 模型与讲话人格配置流程
+whenToUse: 当用户要求部署、更新、重启、配置 gori-agent Bot（如 gori-ops、gori-developer），或要求配置 Assistant/Worker 模型、effort、persona/assistantPersona 时使用
+---
+
+# gori-agent Bot 部署与配置流程
+
+本 skill 用于把 `gori-agent` 代码发布到运行机，并配置实例的 Assistant/Worker Kimi Code 模型与讲话人格。核心边界：Assistant 只聊天和调度，Worker 只在已确认 Proposal 中执行；不要绕过 Proposal 状态机。
+
+## 固定路径
+
+- 仓库：`/home/ubuntu/gori-space/gori-agent`
+- 实例根：`${GORI_AGENT_ROOT:-$HOME/.gori-agent}/instances/<bot-id>/`
+- 实例配置：`<instance>/config.json`
+- 实例 state：`<instance>/state/`
+- Assistant Kimi home：`<instance>/state/kimi/assistant/`
+- Worker Kimi home：`<instance>/state/kimi/worker/`
+- 本机 Kimi 基础配置：`$HOME/.kimi-code/config.toml`
+- Kimi OAuth/credentials：`$HOME/.kimi-code/oauth/`、`$HOME/.kimi-code/credentials/`
+
+## 安全纪律
+
+- 不在回复、日志、diff 中输出 platform secret、API key、OAuth 内容、消息正文、完整 chat/user ID。
+- `git commit/push/pull --rebase/reset/clean` 等 git mutation 必须得到用户当次明确授权。
+- 远程机器写入、部署、重启真实 Bot 必须得到用户当次明确授权。
+- 改实例 `config.json` 前必须同目录备份，写入用临时文件 + fsync + atomic rename，最终 `0600`。
+- 旧 state 不删除；需要切换版本时改成时间戳 `.bak` 保留。
+
+## 发布流程
+
+1. **确认源仓库状态**
+   - `git status --short --branch`
+   - 如果本地有未提交改动且用户要求远端部署，先提示：远端 pull 拿不到未提交代码。
+   - 只有用户明确授权后才 commit/push。
+
+2. **本地验收**
+   ```bash
+   npm run typecheck
+   npm test
+   npm run build
+   git diff --check
+   bash -n install.sh gori-agent.sh bin/gori-agent
+   ```
+
+3. **目标机更新**
+   ```bash
+   ssh ubuntu@<host> 'cd /home/ubuntu/gori-space/gori-agent && git pull --ff-only origin master && npm run typecheck && npm test && npm run build'
+   ```
+   - `git pull --ff-only` 失败、工作区脏或分叉时停止并报告，不擅自 reset/rebase。
+
+4. **实例配置**
+   - 先备份 `<instance>/config.json`。
+   - Kimi ACP `bot.agent.args` 必须严格为 `["acp"]`。
+   - Worker 如需独立 Kimi home，设置：
+     ```json
+     "bot": {
+       "agent": {
+         "env": { "KIMI_CODE_HOME": "<instance>/state/kimi/worker" }
+       }
+     }
+     ```
+   - `runtime.acp.promptTimeoutMs` 当前基线为 `14400000`（4 小时）。
+   - `runtime.acp.maxAssistantSessions` 当前基线为 `4`。
+
+5. **旧 state 处理**
+   - state v3 会拒绝旧 v1/v2。
+   - 升级时如需 fresh start，把旧文件移动为：
+     ```text
+     acp-sessions.json.YYYYMMDD-HHMMSS.bak
+     ```
+   - 不覆盖、不删除旧 state。
+
+6. **doctor / restart / status**
+   ```bash
+   bin/gori-agent doctor <bot-id>
+   bin/gori-agent restart <bot-id>
+   bin/gori-agent status <bot-id>
+   ```
+   - Health 必须是 HTTP 200 且 bot/platform identity verified。
+   - restart 前检查是否有 `working` Proposal；working 时先告知用户，避免把 worker 打成 `worker_lost`（重启后该 Proposal 会变为 `pending` 且 `workspaceDirty: true`，需要用户 finish 或 follow_up，并会全局阻塞 start_next）。
+
+## Assistant / Worker 模型配置
+
+Assistant 和 Worker 可以有独立 `KIMI_CODE_HOME`：
+
+```text
+Assistant: <instance>/state/kimi/assistant/config.toml
+Worker:    <instance>/state/kimi/worker/config.toml
+```
+
+流程：
+
+1. 从本机基础配置复制：
+   ```bash
+   cp "$HOME/.kimi-code/config.toml" "<instance>/state/kimi/assistant/config.toml"
+   cp "$HOME/.kimi-code/config.toml" "<instance>/state/kimi/worker/config.toml"
+   ```
+2. 如果使用 managed Kimi 模型，复制 OAuth/credentials：
+   ```bash
+   cp -a "$HOME/.kimi-code/oauth/." "<instance>/state/kimi/<role>/oauth/"
+   cp -a "$HOME/.kimi-code/credentials/." "<instance>/state/kimi/<role>/credentials/"
+   ```
+   目录 `0700`，文件 `0600`，不回显内容。
+3. 设置：
+   ```toml
+   default_model = "<model-alias>"
+   [thinking]
+   enabled = true
+   effort = "<effort>"
+   ```
+4. 校验：
+   ```bash
+   "$HOME/.kimi-code/bin/kimi" doctor config "<instance>/state/kimi/<role>/config.toml"
+   ```
+
+当前生产基线（2026-08-18）：
+
+| Bot | Assistant | Worker |
+|---|---|---|
+| `gori-ops` | `kimi-code/k3-256k`, `high` | `kimi-code/k3-256k`, `high` |
+| `gori-developer` | `kimi-code/k3-256k`, `high` | `kimi-code/k3`, `high` |
+
+注意：`k3-256k` 支持 `low/high/max`，不支持 `medium`；写 `medium` 会按模型默认回落。模型 availability 和 effort 通道异常时，先用只读/小请求验证，再调整。
+
+## Assistant / Worker 人格配置
+
+Config v3 支持：
+
+```json
+{
+  "bot": {
+    "persona": "Worker 的执行边界和安全规则。",
+    "assistantPersona": "Assistant 的讲话人格。"
+  }
+}
+```
+
+- Worker 永远使用 `bot.persona`。
+- Assistant 使用 `bot.assistantPersona`；为空时回退 `bot.persona`。
+- `assistantPersona` 参与 Bot fingerprint；修改后旧 Assistant binding 会因 fingerprint 不匹配自动重建。
+- Assistant 的人话风格由 bootstrap 统一约束；实例 persona 决定角色气质。
+
+当前实例人格：
+
+### gori-ops
+
+```text
+你是 Gori 运维 Assistant。说话像一个靠谱、轻松的运维同事：先给结论，再给原因和下一步；用短句，少术语，不机械复读状态字段。遇到故障先稳住用户，再给可操作选择；不确定就直说。涉及部署、删除、Git mutation、远程写入或共享状态时，用平实的话说明影响并请用户确认；绝不回显 secrets。
+```
+
+### gori-developer
+
+```text
+你是 Gori 开发 Assistant。说话像一位资深开发搭档：直接、清楚、有判断力；先说结论，再给关键改动或验证方式；不堆内部字段和协议词，不机械复读 ID。能确定就明确说，不能确定就直说；遇到风险改动、Git mutation、部署或共享状态变化时，用平实的话说明影响并请用户确认；绝不回显 secrets。
+```
+
+## QQ 发送边界
+
+当前 QQ Bot 没有主动群消息权限，错误码：
+
+```text
+40034105 主动消息失败, 无权限
+```
+
+因此事件通知按方案 B：
+
+- 群聊 worker event 优先使用最近入站消息的 5 分钟被动回复窗口；实现按 4.5 分钟保守判定。
+- 私聊按 60 分钟窗口；实现按 55 分钟保守判定。
+- 超过窗口不主动发；事件进入 pending，下次该 chat 有入站时补发。
+- 无 `msg_id` 时不要发送裸 `msg_seq`。
+- 同一 `msg_id` 的 `msg_seq` 必须由 Gateway 共享递增，正常回复、事件、补发不能各自从 1 开始。
+- `/status` 应能看到 `schedulerState`、`blockedReason`、`lastEventDelivery`、`lastEventError`、`lastEventAt`。
+
+出站图片同样没有主动权限，走同一被动窗口与共享 `msg_seq`：Worker 把给用户看的 png/jpg 存到 workspace 内（建议 `.gori-outbox/`）并在 result envelope 的 `attachments` 上报，runtime 校验 workspace  containment、magic bytes、单张 ≤10MB、最多 3 张；发送时先 `POST /v2/{groups|users}/{id}/files` 上传（`file_type: 1` + base64 `file_data` + `srv_send_msg: false`）再 `msg_type: 7` + `media.file_info` 发送，群/私聊上传的 file_info 不通用。落定事件先发文案再发图；窗口过期补发时按路径重读文件，文件没了降级为文本说明；上传/发送失败不阻断文本。用户后来说「把图发给我」时 Assistant 用 `send_image` action 发同一张图。
+
+## 验收清单
+
+部署完成后至少检查：
+
+```bash
+git status --short --branch
+bin/gori-agent status <bot-id>
+```
+
+并确认：
+
+- runner PID 正常
+- Health HTTP 200 且 identity verified
+- QQ websocket connected/ready（若使用 websocket）
+- 没有 working Proposal 被误重启
+- Assistant/Worker Kimi config 均通过 `kimi doctor config`
+- 日志中无新的 send failed、worker crash、assistant isolation violation

-Binding 保存 agent ID、workspace、native session ID、Bot fingerprint 和时间戳。fingerprint 包含：
+Proposal 状态流：`proposed → queued → working → pending → finished`。`proposed` 必须用户确认才进入 `queued`；proposal 一旦进入 `working`，worker 默认连续执行普通低风险步骤，不为工作区内读写、搜索、本地构建或测试逐步回问，只有遇到高风险动作、关键业务选择、外部阻塞或 dirty/异常目标时才返回 `pending question`；`pending` 就是「等用户决定」，不区分 success/failure；只有 `finish` 把 pending 落定为 `finished(done)`，`cancel`（proposed/queued/pending）落定为 `finished(cancelled)`；没有 working、owner 自己没有 pending、全局没有 workspaceDirty pending 时，最早确认的 queued Proposal 才可通过 confirm 或 start_next 开始。

-每个绑定由当前实例固定的 `platform + chatId` 唯一确定。state v2 header 保存 `botId` 与 platform type；打开 state 时身份不匹配会拒绝启动，避免错误复用另一个实例目录。
+运行链路是三层：
 
-Binding 保存：
+- **Assistant**：每个 conversation（chat + user）一个无工具 ACP 会话，只与用户对话；同群不同用户的会话互相隔离。它把用户意图整理成 Proposal（title、goal、steps），并解释 Worker 的反馈。Assistant 每条回复必须以隐藏 `GORI_ASSISTANT_ACTION_V2` envelope 结尾（`reply` + `actions`），action 只有 `create_proposal`、`confirm`、`adjust_proposal`、`follow_up`、`finish`、`send_image`、`start_next`、`cancel`、`stop`；格式错误只修复一次（envelope 缺闭合标签时先按花括号配平 salvage，失败才修复）。`send_image { path }` 把 Worker 报告过的 workspace 内图片发给用户，与 Worker 附件同样的路径/类型/大小校验。
+- **Proposal**：一份工作单，owner 是 chat + 发起用户；`confirm` / `adjust` / `follow_up` / `start_next` 仍只有发起人本人可操作（runtime 强校验），但为了避免单人把单 worker 队列卡死，`finish` / `stop` / `cancel` 是全板共享动作：任何用户都可对可见 proposal 执行它们。Proposal 板全局共享可见：Assistant prompt 的全板列表包含所有 chat/user 的未完成条目（自己的标 `scope=own`，他人的标 `scope=other` 并附 chat 类型，不暴露 openid 明文），Assistant 可如实向任何用户描述全板状态。状态流为 `proposed → queued → working → pending → finished`。`proposed` 只有用户确认后才进入 `queued`；proposal 一旦进入 `working`，worker 默认连续执行普通低风险步骤，不再逐步回问，只有碰到高风险动作、关键业务选择、外部阻塞或 dirty/异常目标时才返回 `pending question`；`pending` 就是「等用户决定」，不再区分 success/failure；只有 `finish` 把 pending 落定为 `finished(done)`，`cancel` 落定为 `finished(cancelled)`。
+- **Worker**：同一时刻全实例只有一个，在 `bot.workspace` 用 `bot.permissions` policy 执行一个已确认 Proposal。每轮必须以隐藏 `GORI_WORKER_RESULT_V2` envelope 收尾：`PENDING`（`summary` 必填，可带 `question`、`workspaceDirty`），不区分成功/失败，只把结果交给用户。Worker 给用户看的图片（png/jpg）必须保存在 workspace 内（建议 `.gori-outbox/`），并通过 `attachments: [{ path, mimeType? }]`（最多 3 个）上报；runtime 校验路径必须在 workspace 内、magic bytes 为 png/jpg、单张 ≤10MB，违规的丢弃并在事件文本里说明。
 
-- chat key
+确认语义是刻意的：
-- agent ID
-- native ACP session ID
-- workspace
-- Bot fingerprint
-- 创建与更新时间
 
-Bot fingerprint 包含 Bot ID、workspace、persona、agent、permissions、skill 路径/内容 hash 和 bootstrap schema version。任一语义变化后，下一条消息创建新 native session，不恢复旧身份上下文。
+- Worker 落定后 Proposal 进入 `pending`，记录 `summary`、可选 `question` 和 `workspaceDirty`；用户说 `finish`（可带 note）落定为 `finished(done)`，或直接继续说要求：Assistant 发 `follow_up`，runtime 优先 resume 原 worker native session 继续（resume 失败则带 Proposal 上下文新起 session），用户输入的图片附件也随 prompt 给 Worker。
+- 系统**不会**在一个 Proposal 落定后自动开始下一个；只有用户确认新 Proposal 或 Assistant 发出 `start_next` 才会推进队列。
+- 阻塞规则：任何 `working` 全局拒绝 `start_next`/`follow_up`；owner 自己有 `pending` 时拒绝该 owner 的 `start_next`（提示先 finish 或 follow_up）；任何 `workspaceDirty` 的 `pending` 全局拒绝 `start_next`（提示先处理 dirty 工作区）。非 dirty 的 pending 不挡其他用户。
+- `stop` 只对 `working` 生效：停掉 Worker（含进程组清理）并把 Proposal 标记为 `pending`（summary 为「被用户中止」、`workspaceDirty: true`）。
+- Assistant 有 pending 时每轮 prompt 注入 pending card（id/title/summary/question）；Assistant 回复没提到 pending 时，runtime 在回复末尾追加一条人话兜底提醒。
+- Worker working 期间，runtime 把 `session/update` 的工具活动按类别（read/search/write/execute/delegate/other）聚合成实时快照（不含工具参数、输出或正文）；下一轮 Assistant prompt 注入紧凑状态卡（title、运行时长、最后活动类别、各类别计数），Assistant 据此用人话描述进度。调试期状态卡对所有人可见（他人任务会标注 `another user's proposal`）。
+- Gateway 不再有 15/60/180/480 秒的固定时间提醒；Worker 落定结果时通过 Assistant 生成一条事件说明，由平台 adapter 作为**新消息**发给 owner chat（QQ 同样是新消息，不引用原消息）。
 
-首次 prompt 会创建 native session，发送隐藏 bootstrap，bootstrap 成功后才保存 binding。worker 空闲回收后优先 `session/resume`，否则回退 `session/load`。失败 prompt 不会自动重放，因为工具操作可能已有副作用。
+Assistant 隔离与旧 side Session 一致且更严格：
 
-旧 state v1 会被原样保留并明确拒绝；使用新的实例目录开始 state v2，不要手工改写运行中的 state。
+- cwd 位于实例私有 `state/assistant-workspaces/`，目录名由进程随机 salt 和 conversation key（chat + user）计算 HMAC，不直接编码 chat 标识，并且不能与项目 workspace 重叠；重启后按 binding 恢复同一目录。
+- 项目级 `agent.md` override 显式设置 `tools: []` 与 `subagents: []`；ACP 传入空 `mcpServers`；Assistant 只接受 Kimi Code ACP，并强制 permission deny 作为附加层。
+- 除非 `bot.agent.env` 已显式设置，Assistant 进程的 `KIMI_CODE_HOME` 指向实例私有 `state/kimi/assistant/`（`0700`），与真实用户配置隔离。
+- 一旦出现 tool update 或 permission request，即视为隔离违约：当前 turn fail closed、终止整个 ACP 进程组并删除 binding。Worker 的 cancel、timeout、crash 同样按进程组清理工具后代；bootstrap 禁止 `setsid`、`nohup`、detached/daemon/background 遗留进程，主动脱离进程组仍属于无 Bubblewrap/cgroup 方案的信任边界。
+- 每个 ACP worker 以独立进程组运行并携带随机 `GORI_AGENT_WORKER_TOKEN`；runner 重启时会把仍处于 `working` 的 Proposal 校验 token 后清理旧进程组，并标记为 `pending`（`worker_lost`、`workspaceDirty: true`），交给用户 finish 或 follow_up。
+
+state v3（`acp-sessions.json`）只保存 header（version 3、`botId`、platform）和 Assistant binding：conversation key（chat + user）、agent ID、native session ID、assistant workspace、Bot fingerprint 与时间戳。`proposals.json`（version 2）保存 Proposal 记录：title/goal/steps、owner chat、发起用户、状态（`proposed | queued | working | pending | finished`）、pending（`summary`/`question?`/`workspaceDirty?`/`receivedAt`）、finished 的 `finishKind`（`done | cancelled`）/`finishNote?`、worker native session ID 与进程组 PGID/token、时间戳；不保存消息正文。两个 store 都做单 writer lock、串行持久化、临时文件 + fsync + 原子 rename；version 或 identity 不匹配（含旧 state v1/v2）一律拒绝启动并保留原文件，不清空。唯一例外是 proposals v1：打开时先在同目录写 `proposals.json.v1-<timestamp>.bak`（0600）备份，再按固定映射迁移为 v2（SUCCESS/FAILED/NEEDS_CONFIRMATION → pending，completed/failed → finished(done)，cancelled → finished(cancelled)）。
+
+Bot fingerprint 包含 bootstrap schema version、Bot ID、workspace、persona、assistantPersona、agent 定义、permission policy 和 skill 路径/内容 hash；fingerprint 或 agent 不匹配的 binding 会被丢弃并重建 Assistant 会话。失败 prompt 不会自动重放，因为工具操作可能已有副作用。
+
+## Workspace 独占
+
+同一 `GORI_AGENT_ROOT` 下，旧的 `/usr/bin/flock` workspace lease 与 `owner.json` 已退役。`doctor`、外层 `start` 与内部 runner 都对其他实例目录和完整 Config v3 扫描 fail closed，canonical workspace 相同或互为父子都拒绝；不再做配置级 workspace 共享。`setup/start` 还通过实例 lifecycle flock 互斥，父 CLI 把已验证配置摘要传给 runner，配置发生换挡时 runner 拒绝启动。

+- `/confirm`：确认当前用户最近待确认的 `proposed` Proposal（进入队列）。
+- `/finish`：把当前用户最近的 `pending` Proposal 落定为 `finished(done)`。
+- `/stop`：停止当前用户正在执行的 Worker，Proposal 转为 `pending`（被用户中止、dirty）；只有 Proposal 发起人可用。
+- `/cancel`：取消当前用户最近的 `proposed` / `queued` / `pending` Proposal，落定为 `finished(cancelled)`。
 
-同一 chat 串行执行，不同 chat 可并发。
+日常操作以自然语言为主，Assistant 会自己生成 confirm/follow_up/finish/cancel/stop 等 action；这些命令是旁路 Assistant 的兜底入口。未识别的 `/` 命令按普通消息交给 Assistant。
+
+Gateway 不维护普通消息队列或 per-chat task lock，也不再有固定时间（15/60/180/480 秒）的处理中提醒；每条 allowlist 普通消息按 conversation（chat + user）串行交给 AssistantManager。Worker 落定结果（成功、失败或提问）时，AssistantManager 生成事件文案并经 `Gateway.sendEvent` 发出。QQ 无主动消息权限（HTTP 400 / code 40034105）时事件走被动回复窗口：`sendEvent` 引用该 chat 最近一次入站消息（`msg_id` + 递增 `msg_seq`），群聊窗口 5 分钟（按 4.5 分钟保守判定）、C2C 窗口 60 分钟（按 55 分钟保守判定）；超过窗口或没有 messageId 时不发主动消息，记录为 skipped 并在该 chat 下次入站时补发。发送失败只记录不含消息正文或 provider 错误详情的安全日志（仅 HTTP status / QQ code），不影响任务或后续发送。
+
+每条异步入站使用独立、串行的回复流，`replySequence` 从 1 动态递增；同步 webhook 直接返回 JSON 结果。
