-# Agent 通讯修复 Jira Task
-
-- 版本：v1.0
-- 生成日期：2026-04-25
-- 来源：由按文件执行清单、Claude 交叉验证意见整理合并
-- 范围：ACP Agent / Bridge / Remote Control Server / REPL Hook 生命周期
-- 使用方式：这是唯一执行任务文档；每个 `JIRA-*` 小节可直接拆成一个 Jira issue，字段保持统一，便于复制或二次导入。
-
----
-
-## 方案性质
-
-本文档是目标状态式执行方案，不是临时补丁清单。每张 ticket 必须交付明确的代码终态、测试覆盖和回归边界；不得只用局部 workaround 掩盖问题。
-
----
-
-## 执行总则
-
-1. 先边界安全，后内部优化：先修 WS 入站大小与输入校验，避免线上风险扩大。
-2. 单文件可回滚：每个文件内修改保持内聚，便于回滚与 bisect。
-3. 不改协议语义，只修实现缺陷：除 `resource_link` 表达形式统一外，不改变主流程契约。
-4. 每个文件必须有验收输出：要么测试用例，要么日志/指标验证。
-5. 发布前必须确认协议层行为无回归：`stopReason` 决策与 `sessionUpdate` 发送顺序保持稳定。

-### JIRA-001：为 session ingress WebSocket 补齐消息大小限制
-
-- Issue Type：Bug
-- Priority：P0
-- Story Points：3
-- Owner：后端/网关
-- Files：
-  - `packages/remote-control-server/src/routes/v1/session-ingress.ts`
-- 后续票：JIRA-008（同文件 P1 类型与 decode path 收尾）
-
-#### 参考代码位置
-
-- `packages/remote-control-server/src/routes/v1/session-ingress.ts:100-106`
-
-#### 背景
-
-`session-ingress` 当前缺少 WebSocket message size limit。ACP 路由已有类似限制，两个入口边界不一致，可能导致大包占用内存或绕过入口保护。
-
-#### 实施要求
-
-- 新增 `MAX_WS_MESSAGE_SIZE = 10 * 1024 * 1024`，与 ACP 路由的 10MB 上限保持一致。
-- 在 `onMessage` decode 后优先检查 payload size。
-- 超限时执行 `ws.close(1009, "message too large")`。
-- 日志记录 `sessionId`、payload size、limit。
-- 对 `string`、`ArrayBuffer`、`Uint8Array` 进行统一 decode 分流。
-- 非支持类型直接拒绝并记录，不进入业务 handler。
-
-#### 验收标准
-
-- 11MB payload 被 1009 close。
-- 1KB 合法 payload 仍正常进入 handler。
-- 非支持类型 payload 不进入 handler。
-- 不改变 URL、auth、session 解析逻辑。
-
-#### 回归范围
-
-- Remote Control Server session ingress WebSocket。
-- 正常会话消息转发。
-- WebSocket close code 行为。
-
-#### 风险等级
-
-- 中。入口逻辑变更可能影响特殊客户端 payload 类型。
-
-#### 必须验证
-
-- 在 `packages/remote-control-server/src/__tests__/routes.test.ts` 增加 session-ingress WebSocket 大包、小包、坏类型 payload 用例。
-- 运行 `bun run typecheck`。

-### JIRA-002：修复 ACP bridge abort listener 生命周期泄漏
-
-- Issue Type：Bug
-- Priority：P0
-- Story Points：3
-- Owner：核心通讯
-- Files：
-  - `src/services/acp/bridge.ts`
-
-#### 参考代码位置
-
-- `src/services/acp/bridge.ts:576-585`
-
-#### 背景
-
-ACP bridge 的 `Promise.race` abort 分支注册 listener 后缺少完整 cleanup。长会话或高频 next 场景可能出现 listener 累积。
-
-#### 实施要求
-
-- 将 abort race 改为可清理监听器写法。
-- 注册 listener 后保留 handler 引用。
-- `sdkMessages.next()` 先返回时必须 `removeEventListener`。
-- abort、throw、return 等路径都在 `finally` 中清理。
-- 不改变 `stopReason` 决策逻辑。
-- 不改变 `sessionUpdate` 发送顺序。
-
-#### 验收标准
-
-- 模拟 10k 次 next 且不 abort，listener 不增长。
-- abort 场景仍返回 `cancelled`。
-- 原有 streaming/session update 行为无回归。
-
-#### 回归范围
-
-- ACP bridge streaming loop。
-- 用户取消请求。
-- SDK generator 异常路径。
-
-#### 风险等级
-
-- 中。异步控制流变更需要覆盖取消与异常路径。
-
-#### 必须验证
-
-- 新增 listener cleanup 单元测试。
-- 运行 `bun run typecheck`。

-### JIRA-003：优化 ACP agent pending prompt 队列为 O(1) 出队
-
-- Issue Type：Task
-- Priority：P1
-- Story Points：5
-- Owner：核心通讯
-- Files：
-  - `src/services/acp/agent.ts`
-
-#### 参考代码位置
-
-- `src/services/acp/agent.ts:332-339`
-
-#### 背景
-
-当前 pending prompt 队列使用 `Map + sort` 获取下一项，排队量上升时会带来不必要的排序成本。
-
-#### 实施要求
-
-- 改为 `queue: string[]` + `pendingMap: Map<string, PendingPrompt>` 组合。
-- 入队执行 `queue.push(id)` 与 `pendingMap.set(id, prompt)`。
-- 出队从队首惰性跳过已取消项。
-- 取消只从 `pendingMap` 删除，不做数组中间删除。
-- 保持现有取消语义和出队顺序。
-
-#### 验收标准
-
-- 1000 pending prompt 场景下出队顺序正确。
-- 已取消 prompt 不会被 resolve。
-- 出队不再依赖全量 sort。
-- 1000 排队场景下出队耗时低于旧实现；测试记录旧实现复杂度风险和新实现 O(1) 出队路径。
-- 行为与旧实现兼容。
-
-#### 回归范围
-
-- ACP prompt queue。
-- 并发 prompt 请求。
-- prompt cancel / resolve 边界。
-
-#### 风险等级
-
-- 中。队列结构变更可能引入取消边界问题。
-
-#### 必须验证
-
-- 新增 queue 顺序与取消测试。
-- 对 1000 prompt 场景做性能断言或日志记录。

-### JIRA-004：接入真实 settings 读取并校验 ACP permission mode
-
-- Issue Type：Bug
-- Priority：P1
-- Story Points：3
-- Owner：核心通讯
-- Files：
-  - `src/services/acp/agent.ts`
-
-#### 参考代码位置
-
-- `src/services/acp/agent.ts:465-467`
-
-#### 背景
-
-`getSetting()` 当前未真正接入项目配置，导致默认 permission mode 配置无法按预期生效。
-
-#### 实施要求
-
-- 接入项目现有 settings/config 读取逻辑。
-- 仅接受合法 permission mode 枚举值。
-- 非法值 fallback 到 `default`。
-- `_meta.permissionMode` 继续保持最高优先级。
-- 不改变外部协议字段。
-
-#### 验收标准
-
-- settings/defaultMode 能影响默认 permission mode。
-- `_meta.permissionMode` 能覆盖 settings。
-- 非法 settings 值不会传播到运行时。
-- 类型检查通过。
-
-#### 回归范围
-
-- ACP agent session 初始化。
-- 权限模式同步。
-- 客户端 `_meta` 覆盖逻辑。
-
-#### 风险等级
-
-- 中。配置优先级错误会影响权限行为。
-
-#### 必须验证
-
-- 新增 defaultMode / `_meta.permissionMode` 优先级测试。
-- 运行 `bun run typecheck`。

-- Story Points：5
-- Owner：核心通讯
-- Files：
-  - `src/services/acp/agent.ts`
-  - `src/services/acp/bridge.ts`
-  - `src/services/acp/promptConversion.ts`（新增）
-
-#### 参考代码位置
-
-- `src/services/acp/agent.ts:754-758`
-- `src/services/acp/agent.ts:764-785`
-- `src/services/acp/bridge.ts:522-537`
-
-#### 背景
-
-ACP agent 与 bridge 存在重复 prompt 转换逻辑，`resource_link` 等 block 的输出策略容易分叉。
-
-#### 实施要求
-
-- 新增共享转换模块 `src/services/acp/promptConversion.ts`。
-- `agent.ts` 与 `bridge.ts` 改为调用共享转换函数。
-- 删除 `bridge.ts` 中 `promptToQueryContent` 的真实实现；如导出仍需保留，则只允许保留调用共享函数的 wrapper。
-- `resource_link` 输出改为稳定纯文本元信息，禁止 markdown link。
-- 保持其他 block 转换语义不变。
-
-#### 验收标准
-
-- 全仓库仅保留一个真实 prompt 转换实现。
-- 相同 input block 在 agent/bridge 输出一致。
-- `resource_link` 不再输出 `[name](uri)` 形式。
-- 相关测试覆盖转换一致性。
-
-#### 回归范围
-
-- ACP prompt input。
-- bridge query content。
-- resource link prompt 表达。
-
-#### 风险等级
-
-- 中。文本格式变化可能影响下游 prompt 快照或断言。
-
-#### 必须验证
-
-- 新增 shared conversion 单元测试。
-- 全仓库搜索重复转换函数。
-- 运行 `bun run typecheck`。

-### JIRA-006：治理 REPL onInit effect 依赖并补齐 timer cleanup
-
-- Issue Type：Task
-- Priority：P1

-
-#### 参考代码位置
-
-- `src/screens/REPL.tsx:654-662`
-- `src/screens/REPL.tsx:4996-5005`
-
-#### 背景
-
-REPL 中目标初始化 effect 存在 hook dependency suppress，warm-up timer 也需要显式 cleanup，避免频繁挂载/卸载时留下悬挂任务。
-
-#### 实施要求
-
-- 整理 `onInit` 生命周期，使用稳定引用或 effect 内联。
-- 移除目标段 `exhaustive-deps` suppress。
-- 保持 unmount cleanup 行为不变。
-- warm-up effect 中记录 timeout id。
-- cleanup 中执行 `clearTimeout(timeoutId)`。
-- 保留 `alive` 判定作为并发保护。
-
-#### 验收标准
-
-- 目标段不再需要 hooks lint suppress。
-- 高频打开/关闭搜索栏无悬挂 timer 增长。
-- REPL 初始化行为无回归。
-
-#### 回归范围
-
-- REPL 初始化。
-- 搜索栏 warm-up。
-- 组件卸载 cleanup。
-
-#### 风险等级
-
-- 中。React effect 依赖治理可能改变初始化时机。
-
-#### 必须验证
-
-- 运行 lint/typecheck。
-- 手动或测试覆盖 REPL mount/unmount。

-
-#### 参考代码位置
-
-- `packages/remote-control-server/src/routes/acp/index.ts:108-146`
-
-#### 背景
-
-ACP route 中 WebSocket 事件和 socket 参数存在 `any`，降低编译期保护。
-
-#### 实施要求
-
-- 定义最小 WebSocket 事件类型：open/message/close/error。
-- 将 `_evt: any`、`evt: any`、`ws: any` 替换为窄类型。
-- 不改变 payload decode 与大小检查策略。
-- 不改变现有 handler 行为。
-
-#### 验收标准
-
-- 编译期能捕获错误事件字段访问。
-- 现有 WebSocket 行为不变。
-- `bun run typecheck` 通过。
-
-#### 回归范围
-
-- ACP WebSocket route。
-- message decode。

-### JIRA-010：补充 Remote Control Server WebSocket 入站回归测试
-
-- Issue Type：Test
-- Priority：P1
-- Story Points：3
-- Owner：QA/后端
-- Files：
-  - `packages/remote-control-server/src/__tests__/routes.test.ts`
-  - `packages/remote-control-server/src/routes/v1/session-ingress.ts`
-
-#### 覆盖场景
-
-- 11MB session ingress payload 被 1009 close（与 10MB 上限对齐）。
-- 合法小 payload 正常进入 handler。
-- 非支持 payload 类型被拒绝。
-- 日志或可观测输出包含 sessionId、payload size、limit。
-
-#### 验收标准
-
-- 11MB payload 被 1009 close（与 10MB 上限对齐）。
-- 新增测试稳定通过。
-- 不启动真实外部服务。
-- 不改变现有 route public contract。
-
-#### 回归范围
-
-- RCS session ingress route。
-- WebSocket message handling。
-- close code 行为。
-
-#### 风险等级
-
-- 中。测试需要适配现有 WebSocket/mock 基础设施。
-
-#### 必须验证
-
-- 运行 RCS package 相关测试。
-- 运行 `bun run typecheck`。

-## 推荐执行顺序
-
-执行节奏与原计划保持一致：先完成 P0 全部改动和冒烟验证，再启动 P1 改造；测试票可穿插执行，但不得绕过 P0 gate。
-
-1. JIRA-001：先封入口大包风险。
-2. JIRA-002：修长会话 listener 生命周期。
-3. JIRA-010：补 RCS 入站测试，锁住 P0 行为。
-4. JIRA-003：优化 pending prompt queue。
-5. JIRA-004：接入 settings/defaultMode。
-6. JIRA-005：单源化 prompt 转换。
-7. JIRA-009：补 ACP 回归测试。
-8. JIRA-006：治理 REPL effect/timer。
-9. JIRA-007：收敛 ACP route 类型。
-10. JIRA-008：收敛 session ingress 类型与 decode path。

-# Agent 通讯修复问题文档
-
-- 版本：v1.0
-- 生成日期：2026-04-25
-- 范围：ACP Agent / Bridge / Remote Control Server / REPL Hook 生命周期
-- 配套执行文档：`docs/internals/agent-comm-fix-jira-tasks.md`
-- 目的：保留决策前要问的问题、交叉验证提示词和已确认结论；不要在这里写 Jira 执行步骤。
-
----
-
-## 1. 当前已确认结论
-
-- 只保留两份交付文档：本问题文档 + Jira Task 文档。
-- Jira Task 文档是唯一执行入口，包含 Owner、优先级、文件范围、验收标准、风险和验证建议。
-- Claude 交叉验证结论：整体通过，无 blocking findings；建议补充协议回归 gate、JIRA-001/008 依赖、代码参考位置和阈值一致性，这些建议已合并到 Jira Task 文档。
-- 本次已进入业务代码修复阶段，必须运行 `bun run typecheck` 和相关回归测试。
-
----
-
-## 2. 执行前必须问清的问题
-
-1. `session-ingress` 的 WebSocket 上限是否固定为 10MB，并与 ACP route 保持一致？
-2. 超限 close code 是否统一使用 `1009`，close reason 是否固定为 `message too large`？
-3. `resource_link` 的纯文本格式是否已有下游依赖，能否替代当前 markdown link 表达？
-4. ACP permission mode 的真实 settings key 是哪个，非法值 fallback 是否统一为 `default`？
-5. `_meta.permissionMode` 是否必须始终覆盖 settings/defaultMode？
-6. abort listener 测试中，是否能通过 mock signal 或计数器稳定证明 10k next 后无 listener 累积？
-7. pending prompt queue 的取消语义是否允许惰性清理，而不是立刻从数组中删除？
-8. REPL hook suppress 的清理范围是否只限目标段，不顺手改其他 decompiled React Compiler 结构？
-9. RCS WebSocket 测试应放在现有哪个 `__tests__` 布局下，是否已有 route/mock 基础设施可复用？
-10. 发布 gate 是否必须包含 `stopReason` 决策与 `sessionUpdate` 发送顺序不回归？
-
----
-
-## 3. 给 Claude 或 Reviewer 的复核问题
-
-```text
-请作为外部审查者，复核 docs/internals/agent-comm-fix-jira-tasks.md。
-
-请检查：
-1. 是否仍满足“按文件分工的执行清单”和“Jira task 文档”要求。
-2. 是否存在遗漏的文件、验收标准、风险或前置依赖。
-3. 是否有重复、误导执行者、优先级不合理或测试不可落地的问题。
-4. 是否还有必须阻断实施的 finding。
-
-请用中文输出：
-- Verdict
-- Blocking Findings
-- Non-blocking Findings
-- Suggested Edits
-- Final Recommendation
-
-不要修改文件，只输出审查意见。
-```
-
----
-
-## 4. 已处理的复核建议
-
-- Release Checklist 已补充协议层行为无回归 gate。
-- JIRA-001 与 JIRA-008 已明确同文件前后置关系。
-- JIRA-001 到 JIRA-008 已补充参考代码位置。
-- JIRA-003 已补回 1000 排队场景下的出队耗时验收。
-- JIRA-008 story points 已从 2 调整为 3。
-- JIRA-010 已明确 11MB payload 对齐 10MB 上限并触发 1009 close。
-- 推荐执行顺序已明确 P0 gate：P0 全部改动和冒烟验证完成后，再启动 P1 改造。
-
----
-
-## 5. 不在本文档维护的内容
-
-- 不维护 Jira ticket 正文；统一在 `docs/internals/agent-comm-fix-jira-tasks.md` 修改。
-- 不维护业务代码实现方案；实现时按具体 ticket 读取对应文件。
-- 不维护历史中间稿；旧执行清单已合并进 Jira Task 文档。
