fix: 修复长时间运行会话的内存泄漏问题
/clear 时释放 STATE 中保存的大块数据（API 请求/分类器请求/模型统计），全屏模式增加 500 条消息上限防止无限增长，修复 progress 消息去重逻辑避免交错消息导致重复累积（观察到 13k+ 条目/1GB+ 堆）。 Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

-# fix-issue: GitHub Issue 修复工作流
-
-你是一个专门处理 GitHub issue 的修复助手。收到 issue 后，你将自主完成从分析到提交的全流程。
-
-## 输入格式
-
-支持两种输入方式：
-
-1. **URL 方式**：用户提供 GitHub issue URL（如 `https://github.com/owner/repo/issues/123`）
-2. **描述方式**：用户直接描述问题（如 "登录页面点击提交按钮后崩溃" 或 "issue #456 的分页有问题"）
-
-如果是 URL 方式，用 `gh` 命令获取 issue 信息。如果是描述方式，直接基于描述工作。
-
-## 工作流程
-
-### 阶段一：信息收集
-
-**URL 方式：**
-
-```bash
-# 获取 issue 内容和元信息
-gh issue view <number> --repo <owner/repo> --json title,body,labels,assignees,comments,state
-```
-
-提取以下信息：
- 问题标题和描述
- Labels（bug、enhancement、documentation 等）
- 评论中的补充信息（复现步骤、环境、错误日志、截图描述）
- 是否有关联的 PR 或重复 issue
-
-**描述方式：**
-
-基于用户提供的描述理解问题。如果信息不足，用 AskUserQuestion 补充询问（只问一次，不要反复追问）。
-
-### 阶段二：问题分析与复杂度评估
-
-分析收集到的信息，评估问题：
-
-1. **问题本质**：这是一个什么类型的问题？（bug / 文档 / 性能 / 安全 / 重构）
-2. **影响范围**：大概涉及哪些模块或文件？
-3. **复杂度**：简单（单文件修复） / 中等（多文件但逻辑清晰） / 复杂（多模块耦合、需求不明确、或无法定位根因）
-
-**复杂度判断规则：**
-
-如果满足以下任一条件，判定为"复杂"，**必须停下来向用户汇报**，等用户决定下一步：
- 无法确定问题的根因（多个可能的嫌疑点）
- 修复可能影响 3 个以上模块
- issue 描述模糊，存在多种理解方式
- 需要添加新功能而非修复现有缺陷
- 涉及数据库迁移、API 契约变更等破坏性修改
-
-汇报时说明：问题分析结果、可能的修复方向、以及为什么需要用户决策。
-
-### 阶段三：工作区检查
-
-开始修复前检查工作区状态：
-
-```bash
-git status
-git stash list
-```
-
- 如果工作区有未提交的更改，提醒用户先处理（stash 或提交），**不要自动 stash 或丢弃更改**
- 如果工作区干净，直接进入下一步
- 在当前分支上直接修复，不创建新分支
-
-### 阶段四：代码定位与修复
-
-1. 使用 Explorer subagent（`subagent_type: "Explore"`）探索代码库，定位问题相关代码。给 Explorer 足够的上下文——把 issue 的关键信息告诉它
-2. 阅读相关代码，理解当前实现
-3. 制定修复方案并实施代码修改
-
-修复时遵循项目现有的代码风格和约定。参考 CLAUDE.md 中的项目规范。
-
-### 阶段五：验证
-
-修复完成后自动运行测试：
-
-```bash
-bun test
-```
-
-**测试失败处理：**
- 分析失败原因，判断是否由本次修复引起
- 如果是本次修复引起的，重新分析问题并修复，然后重跑测试
- 最多重试 **2 次**（总共最多 3 次测试运行：初次 + 2 次重试）
- 如果 2 次重试后仍然失败，停下来汇报失败原因和已尝试的方案，交给用户处理
-
-### 阶段六：提交
-
-测试通过后提交修复。
-
-**提交策略：**
- 涉及多文件修改时，按逻辑分组提交（例如："修复数据层校验逻辑" 和 "修复 UI 层错误提示" 分开提交）
- 单文件或逻辑简单的修复直接一次提交
-
-**Commit message 格式：**
-
-```
-fix: 简短描述 (#issue编号)
-```
-
-示例：
- `fix: 修复登录页提交按钮点击后崩溃的问题 (#123)`
- `fix: 修正分页组件页码计算逻辑 (#456)`
- `fix: 更新 API 文档中的错误返回值描述 (#789)`
-
-对于非 bug 类型，对应调整 type：
- 文档问题：`docs: 修正 xxx 描述 (#issue)`
- 性能问题：`perf: 优化 xxx 性能 (#issue)`
- 重构：`refactor: 重构 xxx (#issue)`
-
-提交后不自动创建 PR，也不输出完成提示。静默完成。
-
-## 错误处理
-
- **`gh` 命令失败**：可能是 issue 不存在或权限不足。把错误信息展示给用户，让他们检查
- **找不到相关代码**：扩大搜索范围，如果仍然找不到，停下来告诉用户，附上已搜索的范围
- **测试超时**：如果是测试本身的问题（非修复引起），告知用户并跳过测试环节
- **合并冲突**：不会发生（在当前分支直接修复），但如果 `git status` 显示冲突，停下来让用户处理
-
-## 全流程示例
-
-用户说：`帮我修一下 https://github.com/owner/repo/issues/42`
-
-1. 运行 `gh issue view 42 --repo owner/repo --json ...`，获取 issue 信息
-2. 分析：issue 标题是"用户注册时邮箱校验失败"，评论中有复现步骤和错误日志。复杂度评估：简单（单文件修复）
-3. `git status` 检查工作区干净
-4. 用 Explore agent 搜索 "email" "validate" "register" 相关代码
-5. 阅读 `src/services/auth/register.ts`，发现邮箱正则表达式不完整
-6. 修复正则表达式
-7. `bun test` → 通过
-8. `git commit -m "fix: 修复用户注册时邮箱校验正则表达式不完整的问题 (#42)"`
-9. 静默完成

+- **Anthropic STT（默认）**：通过 WebSocket 流式传输到 Nova 3 端点，需要 Anthropic OAuth
+- **豆包 ASR（Doubao）**：通过 `doubaoime-asr` 包的 AsyncGenerator 协议流式识别，使用独立凭证文件，无需 Anthropic OAuth

 ### 核心特性

 - **Push-to-Talk**：长按空格键录音，释放后自动发送
 - **流式转录**：录音过程中实时显示中间转录结果
 - **无缝集成**：转录文本直接作为用户消息提交到对话

+### 3.5 豆包 ASR 适配器设计
+
+文件：`src/services/doubaoSTT.ts`
+
+豆包后端使用适配器模式，将 `doubaoime-asr` 的 AsyncGenerator 协议桥接到 `VoiceStreamConnection` 接口：
+
+**AudioChunkQueue** — push 式异步队列：
+- 实现 `AsyncIterable<Uint8Array>` 接口
+- `push(chunk)` 将音频数据入队，`push(null)` 发送结束信号
+- 内部维护等待者（waiting）和缓冲队列（chunks）两个状态
+
+**connectDoubaoStream()** — 连接入口：
+- 动态导入 `doubaoime-asr`（optionalDependencies）
+- 从 `~/.claude/tts/doubao/credentials.json` 加载凭证
+- 创建 AudioChunkQueue 和 VoiceStreamConnection
+- 立即触发 `onReady`（避免与 useVoice 的音频缓冲死锁）
+- `finalize()` 立即返回（豆包在录音过程中已返回结果）
+- 后台 async IIFE 消费 `transcribeRealtime` generator，映射响应类型到回调
+
+**响应类型映射**：
+
+| doubaoime-asr ResponseType | 回调映射 |
+|----------------------------|----------|
+| SESSION_STARTED | 日志记录 |
+| VAD_START | 日志记录 |
+| INTERIM_RESULT | `onTranscript(text, false)` |
+| FINAL_RESULT | `onTranscript(text, true)` |
+| ERROR | `onError(errorMsg)` |
+| SESSION_FINISHED | 日志记录 |
+
+### 3.6 后端选择逻辑
+
+文件：`src/hooks/useVoice.ts`
+
+```ts
+// 判断当前 provider
+isDoubaoProvider() → 读取 settings.voiceProvider
+
+// handleKeyEvent 中的可用性检查
+const sttAvailable = isDoubaoProvider()
+  ? isDoubaoAvailableSync()    // 乐观检查（首次返回 true）
+  : isVoiceStreamAvailable()   // Anthropic WebSocket 检查
+
+// attemptConnect 中的连接函数选择
+const connectFn = isDoubaoProvider()
+  ? connectDoubaoStream
+  : connectVoiceStream
+```
+
+豆包后端的特殊处理：
+- 跳过 `getVoiceKeyterms()` 调用（豆包无需关键词提示）
+- 跳过 Focus Mode（`if (!enabled || !focusMode || isDoubaoProvider())`）

 ## 四、关键设计决策

-1. **OAuth 独占**：语音模式使用 `voice_stream` 端点（claude.ai），仅 Anthropic OAuth 用户可用。API key、Bedrock、Vertex 用户无法使用
-2. **GrowthBook 负向门控**：`tengu_amber_quartz_disabled` 默认 `false`，新安装自动可用（无需等 GrowthBook 初始化）
-3. **Keychain 缓存**：`getClaudeAIOAuthTokens()` 首次调用访问 macOS keychain（~20-50ms），后续缓存命中
-4. **独立于主 feature flag**：`isVoiceGrowthBookEnabled()` 在 feature flag 关闭时短路返回 `false`，不触发任何模块加载
+1. **双后端共存**：豆包后端作为独立适配器与 Anthropic 后端并存，不替换原有流程，通过 `voiceProvider` 设置切换
+2. **设置持久化**：`voiceProvider` 存储在 `settings.json`，通过 `/voice` 命令修改，跨会话生效
+3. **OAuth 独占（Anthropic）**：Anthropic 后端使用 `voice_stream` 端点（claude.ai），仅 OAuth 用户可用
+4. **豆包无需 OAuth**：豆包后端使用独立凭证文件，不依赖 Anthropic 认证，通过 `isVoiceAvailable()` 放宽门控
+5. **GrowthBook 负向门控**：`tengu_amber_quartz_disabled` 默认 `false`，新安装自动可用
+6. **onReady 立即触发**：豆包后端在连接建立后立即触发 `onReady`，避免与 useVoice 音频缓冲的时序死锁（Anthropic 需要等待 WebSocket 握手）
+7. **finalize() 立即返回**：豆包在录音过程中已返回所有结果，用户抬手时无需等待处理
+8. **乐观可用性检查**：`isDoubaoAvailableSync()` 在首次调用时返回 `true`，实际导入错误在 `connectDoubaoStream` 中处理
+9. **optionalDependencies**：`doubaoime-asr` 作为可选依赖，安装失败不影响 Anthropic 后端

+# 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。
+
+---
+
+## Epic
+
+### JIRA-EPIC-001：提升 Agent 通讯链路稳定性与边界安全
+
+- Issue Type：Epic
+- Priority：P0
+- Owner：核心通讯 / 后端网关 / QA
+- Scope：ACP Agent、ACP Bridge、Remote Control Server、REPL 初始化生命周期
+- Goal：修复长会话资源泄漏、补齐 WebSocket 入站边界、统一 prompt 转换、收敛类型风险，并补充关键回归测试。
+
+#### Epic 验收标准
+
+- `bun run typecheck` 0 error。
+- P0 WebSocket 超大消息拒绝逻辑已实现并覆盖测试。
+- ACP bridge abort listener 生命周期无累积。
+- prompt 转换实现单源化。
+- settings/defaultMode 能真实影响 ACP permission mode，且 `_meta.permissionMode` 保持最高优先级。
+- REPL 目标 hook suppress 清理完成，timer cleanup 完整。
+
+---
+
+## P0 Tickets
+
+### 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`。
+

+
+## P1 Tickets
+
+### 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

+
+### 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。

+- `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

+- `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

+# 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-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。

-# Pokémon Battle 实现审查报告
-
-> 审查日期：2026-04-23
-> 审查范围：`packages/pokemon/` 全部源码（battle、core、dex、ui）
-> 对比基准：原版 Pokémon 核心系列游戏（Gen 9：Scarlet/Violet）
-> 更新日期：2026-04-24 — 修复了 #1, #2, #3, #4, #6, #7, #8, #13
-
---
-
-## 一、严重问题（核心机制错误）
-
-### 1. XP 计算公式与原版不符
-
-**文件**: `src/battle/settlement.ts:30-31`
-
-```ts
-const baseXp = (oppSpecies?.baseStats?.hp ?? 50) * opponentLevel / 7
-```
-
-原版 Gen 9 的 XP 计算公式为：
-
-```
-XP = (baseXP × opponentLevel × isTraded × isParticipating) / 7 × partySizeModifier
-```
-
-当前实现存在以下错误：
-
- **baseXP 不等于 baseStats.hp**。每只宝可梦有独立的 `base_experience` 值（例如妙蛙种子是 64，皮卡丘是 112），而不是 HP 种族值。目前用 `baseStats.hp` 做代理完全是错的。
- **缺少 traded Pokémon 1.5x 加成**。
- **缺少参与战斗的宝可梦分摊机制**（原版中只有实际参与战斗的宝可梦获得 XP）。
- **缺少 Lucky Egg 1.5x 加成**。
- **缺少 Affection 加成**（Gen 6+）。
-
-### 2. EV 收益完全自造，不使用真实数据
-
-**文件**: `src/battle/settlement.ts:176-191`
-
-```ts
-function getEvYield(speciesId: string): Record<string, number> {
-  // @pkmn/sim Dex.species doesn't have evs field
-  // Use baseStats as proxy: highest base stat gets 1-2 EVs
-  ...
-}
-```
-
-原版中每只宝可梦有固定的 EV yield（如妙蛙种子击倒后给 HP+1，皮卡丘给 Speed+2）。这些数据在 `@pkmn/data` 中是有的（`species.evs`），但代码误以为 `@pkmn/sim` 没有这个字段，就自造了一个「最高种族值 → 2 EV，第二高 → 1 EV」的算法，与原版完全不同。
-
-### 3. 物品使用在战斗中无效
-
-**文件**: `src/battle/engine.ts:436-438`
-
-```ts
-case 'item':
-  p1Choice = 'move 1'  // fallback to move 1
-  break
-```
-
-当玩家使用物品（如药水）时，代码直接忽略了，改为使用第一个招式。原版中物品使用是战斗的核心部分——回复药、状态治愈药、精灵球等都有完整的效果。
-
-### 4. 逃跑功能未实现
-
-**文件**: `src/ui/BattleFlow.tsx:314`
-
-```ts
-case 3: // 逃跑 — show message
-  return
-```
-
-战斗菜单中「逃跑」按钮存在但点击后什么也不做。原版中有逃跑概率计算公式（基于速度对比），对野外战斗是核心机制。
-
-### 5. 对手（p2）不支持多精灵队伍
-
-**文件**: `src/battle/engine.ts:61-67`
-
-```ts
-function wildPokemonToSetString(speciesId: SpeciesId, level: number): string {
-  ...
-  return [species.name, `Level: ${level}`, `Ability: ${ability}`, ...moves.map(m => `- ${m}`)].join('\n')
-}
-```
-
-对手始终只有一只宝可梦（野生宝可梦模式）。没有 Trainer Battle 的概念——对手不能有多只精灵、不能换人、不能使用物品。虽然 AI 在精灵倒下后会自动换人（`executeSwitch` 中有处理），但 `createBattle` 本身只接受单个对手 species。
-
---
-
-## 二、中等问题（机制简化/缺失）
-
-### 6. AI 过于简单
-
-**文件**: `src/battle/ai.ts:6-13`
-
-```ts
-export function chooseAIMove(pokemon: BattlePokemon): number {
-  const usable = pokemon.moves
-    .map((m, i) => ({ move: m, index: i }))
-    .filter(({ move }) => move.pp > 0 && !move.disabled)
-  if (usable.length === 0) return 0
-  return usable[Math.floor(Math.random() * usable.length)]!.index
-}
-```
-
-AI 只是随机选择一个可用招式。原版 NPC AI 至少会考虑：
-
- **属性克制**：优先使用效果绝佳的招式
- **状态技 vs 攻击技**的权衡
- **HP 低时**可能使用回复招式
- **玩家属性**：避免使用被抵抗的招式
- 不会换人、不会使用物品
-
-### 7. 野生宝可梦的招式是按属性硬编码的
-
-**文件**: `src/battle/engine.ts:69-94`
-
-```ts
-function getSpeciesMoves(speciesId: string, _level: number): string[] {
-  ...
-  const basicMoves: Record<string, string[]> = {
-    normal: ['Tackle', 'Scratch'],
-    fire: ['Ember', 'FireSpin'],
-    ...
-  }
-  return basicMoves[type] ?? ['Tackle', 'Scratch']
-}
-```
-
-野生对手的招式不是从 learnset 中获取的，而是按第一属性硬编码了固定招式。`_level` 参数被完全忽略了——原版中不同等级的野生宝可梦应该有不同的招式组合。
-
-### 8. 进化系统不完整
-
-**文件**: `src/dex/evolution.ts` + `src/battle/settlement.ts:92-106`
-
- 只处理了 `evoType` 为 `level_up`、`item`、`trade`、`friendship` 四种类型
- **只取第一个进化目标** (`dex.evos[0]`)，忽略了分支进化（如伊布的多种进化）
- **没有进化石使用的交互**（使用雷之石等道具触发进化）
- **没有通讯交换进化**
- **没有条件进化**（如知道特定招式、特定时间、特定地点等 Gen 9 新增条件）
-
-### 9. 能力值计算缺少特性/道具修正
-
-**文件**: `src/core/creature.ts:51-73`
-
-`calculateStats` 只计算基础能力值，没有考虑：
-
- **特性对能力值的修正**（如 Hustle 增加攻击降低命中）
- **道具对能力值的修正**（如 Choice Band 增加攻击 50%）
-
-注：性格修正虽然传入了 `nature`，但由 `@pkmn/data` 的 `gen.stats.calc` 内部处理，这部分是正确的。
-
-### 10. 捕获系统完全缺失
-
-没有任何捕获野生宝可梦的机制：
-
- 没有 Pokeball 道具的实际效果
- 没有捕获率计算（Shake check 公式）
- 战斗结束后不能获得对手宝可梦
- 虽然数据中有 `captureRate` 字段和 `pokeball` 字段，但从未使用
-
-### 11. 状态异常处理不完整
-
-**文件**: `src/battle/engine.ts:130-140`
-
-只映射了 6 种基本状态（中毒、剧毒、灼伤、麻痹、冰冻、睡眠），但缺少：
-
- **混乱 (Confusion)**：不在 status 中，是 volatile status
- **着迷 (Infatuation)**：同上
- **畏缩 (Flinch)**：同上
- 所有 volatile status（暂时性状态）都未追踪
-
-### 12. 天气/场地效果未完整追踪
-
-**文件**: `src/battle/engine.ts:153-173`
-
- `projectState` 中天气只在初始化时从 `prevConditions` 传入，不会自动更新
- `mapWeather` 不区分 Primal Weather（原始回归天气）和普通天气
- **场地效果（Electric Terrain、Grassy Terrain 等）** 被映射为 `fieldCondition` 事件，但没有影响战斗状态的逻辑
-
-注：底层 `@pkmn/sim` 会正确处理这些效果，只是上层状态投影不完整，导致 UI 无法正确显示。
-
---
-
-## 三、轻度问题（数值/细节偏差）
-
-### 13. Growth Rate 数据覆盖不全
-
-**文件**: `src/dex/species.ts:38-99`
-
-只有 9 个物种（御三家 + 皮卡丘）有正确的 `growthRate` 数据，其余全部使用默认值 `medium-slow`。实际上超过 1000 个物种各有不同的成长速率。这导致 XP 计算对大部分物种不正确。
-
-### 14. 闪光概率未使用 PID 计算
-
-**文件**: `src/core/creature.ts:25`
-
-```ts
-const isShiny = Math.random() < species.shinyChance  // 1/4096
-```
-
-原版 Gen 9 的闪光判定基于 Personality Value（32 位 PID）的异或运算，不是简单的随机概率。Shiny Charm 等道具的加成也无法体现。
-
-### 15. IV 生成算法不是真正的 LCRNG
-
-**文件**: `src/core/creature.ts:108-122`
-
-```ts
-function generateIVs(seed: number): Record<StatName, number> {
-  let s = seed
-  const nextRand = () => {
-    s = (s * 1103515245 + 12345) & 0x7fffffff
-    return s
-  }
-```
-
-原版 Gen 3+ 使用的是完全不同的随机数生成器。更重要的是，Gen 3-5 的 IV 是通过 PID 的高位/低位直接提取的，不是独立随机。
-
-### 16. 性别判定阈值计算偏差
-
-**文件**: `src/core/gender.ts:12-13`
-
-```ts
-const threshold = (speciesData.genderRate / 8) * 256
-return (seed % 256) < threshold ? 'female' : 'male'
-```
-
-原版中性别由 PID 的低 8 位与 `genderRate` 直接比较决定，不需要乘 256 再取阈值。当前实现引入了不必要的精度损失。
-
-### 17. 蛋系统与原版差异巨大
-
-**文件**: `src/core/egg.ts`
-
- **获得条件**：原版通过培育屋/寄养屋繁殖，当前通过「连续编码 3 天 + 每 50 回合」获得
- **孵化步数**：基于 captureRate 反推，而不是物种真实的 `hatch_counter` 数据
- **没有遗传招式**：原版中蛋可以遗传父母双方的招式
- **没有个体值遗传**：原版中蛋会随机继承父母的某些 IV
- **没有球种遗传**：原版中蛋继承母亲的球种
-
-### 18. 多语言名称覆盖极少
-
-**文件**: `src/dex/names.ts`
-
-只有 10 个物种有中/英/日三语名称，其余 1000+ 个物种只回退到英文名。这对于中文/日文用户来说体验不完整。
-
-### 19. 缺少 Held Item 获取途径
-
-战斗中 `heldItem` 被正确传入 Showdown 格式，所以底层模拟会处理道具效果。但是：
-
- 没有获得/装备道具的途径
- 没有商店系统
- 所有野生对手没有道具
- 玩家的宝可梦默认 `heldItem: null`
-
-### 20. Ability 系统不完整
-
- `getDefaultAbility` 只取第一个非隐藏特性
- 没有隐藏特性（Hidden Ability）的选择
- 没有特性胶囊/特性补丁的使用
- 底层 Showdown 会正确处理特性效果（如 Intimidate、Levitate），但 UI 层不显示特性触发
-

-## 四、问题汇总
-
-| 严重程度 | 数量 | 编号 |
-|---------|------|------|
-| 严重（核心机制错误） | 5 | #1 ~ #5 |
-| 中等（机制简化/缺失） | 7 | #6 ~ #12 |
-| 轻度（数值/细节偏差） | 8 | #13 ~ #20 |
-

-
-## 五、优先修复建议
-
-按影响面从大到小排列：
-
-1. **修复 XP 和 EV 计算（#1, #2）**：从 `@pkmn/data` 获取真实的 `base_experience` 和 `evs` 数据，替换当前的代理算法。这两个问题直接影响所有战斗的成长反馈。
-2. **实现物品使用（#3）**：至少支持 Potion（回复 HP）和状态治愈药。这是战斗中最基本的交互。
-3. **实现逃跑（#4）**：需要添加逃跑概率公式和对应的 Showdown 协议处理。
-4. **修复野生对手招式（#7）**：从 learnset 中按等级获取招式，替换硬编码映射。
-5. **补全 Growth Rate 数据（#13）**：从 PokeAPI 或 `@pkmn/data` 批量导入，而非只覆盖 9 个物种。
-
---
-
-## 六、做得好的部分
-
- **底层战斗引擎（`@pkmn/sim`）集成正确**：属性克制、伤害公式、能力值计算、特性效果等核心数学由 Pokémon Showdown 引擎处理，结果与原版一致。
- **EV 上限正确**：单项 252 / 总计 510，与原版一致。
- **XP 经验曲线公式正确**：6 种 Growth Rate 的计算公式（erratic、fluctuating 等）与原版完全一致。
- **Nature 系统完整**：25 个性格及其加成/减益效果通过 `@pkmn/data` 正确获取。
- **Learnset 查询正确**：从 `Dex.data.Learnsets` 获取招式学习表，支持跨代回退。
- **状态异常映射基本正确**：6 种主要状态的 Showdown 协议映射准确。
- **战斗测试覆盖全面**：包括属性克制、强制换人、多精灵队伍等场景的集成测试。

-## 七、修复记录（2026-04-24）
-
-### 已修复
-
-| 编号 | 问题 | 修复方式 |
-|------|------|---------|
-| #1 | XP 使用 baseStats.hp | 从 PokeAPI 获取真实 `base_experience`，存入 `pokedex-data.ts`，公式改为 `baseXP × level / 7` |
-| #2 | EV yield 伪造 | 从 PokeAPI 获取真实 EV yield 数据（1024 个物种），存入 `pokedex-data.ts` |
-| #3 | 物品使用无效 | 实现 Potion/HyperPotion/FullRestore 等回复药效果，直接操作 Battle 对象 HP，消耗背包物品 |
-| #4 | 逃跑未实现 | 实现 Gen 9 逃跑概率公式 `f = (playerSpeed × 128 / opponentSpeed + 30 × attempts) % 256`，成功时 forfeit 结束战斗 |
-| #6 | AI 纯随机 | AI 现在优先选克制招式（70%），避免被抵抗招式和蓄力招式，状态技最低优先级 |
-| #7 | 野生招式硬编码 | 从 `Dex.data.Learnsets` 按等级获取升级招式（最后 4 个），替换按属性硬编码映射 |
-| #8 | 进化只取第一目标 | 检查所有 `evos` 目标，支持分支进化，增加友谊度进化检测 |
-| #13 | Growth Rate 只覆盖 9 个 | 从 PokeAPI 批量导入所有 1024 个物种的 growth rate 数据 |
-| #5 | 多精灵对战不支持 | `createBattle` 支持传入 `OpponentEntry[]`，AI 换人时考虑属性克制 |
-| #10 | 缺少捕获系统 | 新增 `capture.ts`，实现 Gen 9 捕获率公式，支持精灵球/状态修正 |
-| #11 | 缺少 volatile status | 新增 `VolatileStatus` 类型，`BattlePokemon` 添加 `volatileStatus` 字段 |
-| #12 | 天气/地形未投影 | 确认 `projectState` 从 `battle.field.weather/terrain` 读取 |
-| #14 | Shiny 检测用随机 | 改为 Gen 3+ PID XOR 方法，阈值 < 16（Gen 8+ 1/4096 概率） |
-| #15 | IV 生成用 LCRNG | 改为 Gen 3+ PID 位提取法（word1/word2 各取 3 个 5-bit IV） |
-| #16 | 性别阈值精度丢失 | 从 `(rate/8)*256` 改为 `rate*32` 直接比较，消除浮点精度问题 |
-| #17 | 蛋孵化步数用 captureRate | 改为使用真实 `hatchCounter` 数据（步数 = cycles × 257），支持进化阶段回退 |
-| #18 | 多语言名称仅 10 个 | 创建 fetch 脚本获取全量中/日名称，`names.ts` 支持动态加载生成数据 |
-| #19 | 野生对手无道具 | 添加 `rollWildHeldItem`：5% 物种专属道具、5% 树果、3% 属性增强道具 |
-| #20 | Ability 只有第一个 | 新增 `randomAbility`/`getAbilities`，隐藏特性 5% 概率，第二特性 20% 概率 |
