+## Notes Generation
+
+At session end, generate a learner-facing notes file at `{topic-slug}/{topic-slug}-notes.md`. This file is **written for the learner to review later**, not for the tutor. It should be self-contained and organized as a quick-reference.
+
+### Notes Structure
+
+```markdown
+# {Topic} 核心笔记
+
+## 1. {Section Name}
+{Key concept, mechanism, or principle}
+* **One-line summary**: {what it does / why it matters}
+* **Detail**: {brief explanation, 2-4 sentences max}
+* **Example** (if applicable): {code snippet, command, or concrete scenario}
+
+---
+
+## 2. {Section Name}
+...
+
+---
+
+## n. 实战参数 / Cheat Sheet (if applicable)
+{Practical commands, config, or quick-reference table}
+
+| Parameter / Concept | What it does | Tuning tip |
+|---------------------|-------------|------------|
+| ... | ... | ... |
+```
+
+### Notes Writing Rules
+
+1. **Start with "what & why"** before "how". Each section should answer: what is this, why does it exist, what problem does it solve.
+2. **Use analogies sparingly but effectively**. Only include an analogy if it clarifies a non-obvious mechanism (e.g., "PagedAttention is like OS virtual memory paging").
+3. **Include trade-offs**. Every optimization or design choice has a cost. Always state it (e.g., "TP improves throughput but increases communication latency").
+4. **Code / command examples should be minimal**. Under 10 lines, self-contained, with comments explaining the key flags.
+5. **Organize by concept dependency**, not by chronological teaching order. Foundation concepts first, advanced ones last.
+6. **No quiz questions, no misconceptions, no tutor-side notes**. This is a clean reference document.
+7. **Language matches the session**. If the session was in Chinese, notes are in Chinese (technical terms can stay in English).
+8. **Keep it under 150 lines**. If it gets too long, the learner won't review it. Be ruthless about cutting fluff.

+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) and other AI coding agents when working with code in this repository.
+
+## Project Overview
+
+This is a **reverse-engineered / decompiled** version of Anthropic's official Claude Code CLI tool. The goal is to restore core functionality while trimming secondary capabilities. Many modules are stubbed or feature-flagged off. TypeScript strict mode is enforced — **`bunx tsc --noEmit` must pass with zero errors**.
+
+## Git Commit Message Convention
+
+使用 **Conventional Commits** 规范：
+
+```
+<type>: <描述>
+```
+
+常见 type：`feat`、`fix`、`docs`、`chore`、`refactor`
+
+示例：
+- `feat: 添加模型 1M 上下文切换`
+- `fix: 修复初次登陆的校验问题`
+- `chore: remove prefetchOfficialMcpUrls call on startup`
+
+## Commands
+
+```bash
+# Install dependencies
+bun install
+
+# Dev mode (runs cli.tsx with MACRO defines injected via -d flags)
+bun run dev
+
+# Dev mode with debugger (set BUN_INSPECT=9229 to pick port)
+bun run dev:inspect
+
+# Pipe mode
+echo "say hello" | bun run src/entrypoints/cli.tsx -p
+
+# Build (code splitting, outputs dist/cli.js + chunk files)
+bun run build
+
+# Build with Vite (alternative build pipeline)
+bun run build:vite
+
+# Test
+bun test                                    # run all tests
+bun test src/utils/__tests__/hash.test.ts   # run single file
+bun test --coverage                         # with coverage report
+
+# Lint & Format (Biome)
+bun run lint              # check only
+bun run lint:fix          # auto-fix
+bun run format            # format all src/
+
+# Health check
+bun run health
+
+# Check unused exports
+bun run check:unused
+
+# Full check (typecheck + lint + test) — run after completing any task
+bun run test:all
+bun run typecheck
+
+# Remote Control Server
+bun run rcs
+
+# Docs dev server (Mintlify)
+bun run docs:dev
+```
+
+详细的测试规范、覆盖状态和改进计划见 `docs/testing-spec.md`。
+
+## Architecture
+
+### Runtime & Build
+
+- **Runtime**: Bun (not Node.js). All imports, builds, and execution use Bun APIs.
+- **Build**: `build.ts` 执行 `Bun.build()` with `splitting: true`，入口 `src/entrypoints/cli.tsx`，输出 `dist/cli.js` + chunk files。Build 默认启用 19 个 feature（见下方 Feature Flag 段）。构建后自动替换 `import.meta.require` 为 Node.js 兼容版本（产物 bun/node 都可运行）。
+- **Dev mode**: `scripts/dev.ts` 通过 Bun `-d` flag 注入 `MACRO.*` defines，运行 `src/entrypoints/cli.tsx`。默认启用全部 feature。
+- **Module system**: ESM (`"type": "module"`), TSX with `react-jsx` transform.
+- **Monorepo**: Bun workspaces — 15 个 workspace packages + 若干辅助目录 in `packages/` resolved via `workspace:*`。
+- **Lint/Format**: Biome (`biome.json`)。`bun run lint` / `bun run lint:fix` / `bun run format`。
+- **Defines**: 集中管理在 `scripts/defines.ts`。当前版本 `2.1.888`。
+- **CI**: GitHub Actions — `ci.yml`（构建+测试）、`release-rcs.yml`（RCS 发布）、`update-contributors.yml`（自动更新贡献者）。
+
+### Entry & Bootstrap
+
+1. **`src/entrypoints/cli.tsx`** — True entrypoint。`main()` 函数按优先级处理多条快速路径：
+   - `--version` / `-v` — 零模块加载
+   - `--dump-system-prompt` — feature-gated (DUMP_SYSTEM_PROMPT)
+   - `--claude-in-chrome-mcp` / `--chrome-native-host`
+   - `--computer-use-mcp` — 独立 MCP server 模式
+   - `--daemon-worker=<kind>` — feature-gated (DAEMON)
+   - `remote-control` / `rc` / `remote` / `sync` / `bridge` — feature-gated (BRIDGE_MODE)
+   - `daemon` [subcommand] — feature-gated (DAEMON)
+   - `ps` / `logs` / `attach` / `kill` / `--bg` — feature-gated (BG_SESSIONS)
+   - `new` / `list` / `reply` — Template job commands
+   - `environment-runner` / `self-hosted-runner` — BYOC runner
+   - `--tmux` + `--worktree` 组合
+   - 默认路径：加载 `main.tsx` 启动完整 CLI
+2. **`src/main.tsx`** (~6981 行) — Commander.js CLI definition。注册大量 subcommands：`mcp` (serve/add/remove/list...)、`server`、`ssh`、`open`、`auth`、`plugin`、`agents`、`auto-mode`、`doctor`、`update` 等。主 `.action()` 处理器负责权限、MCP、会话恢复、REPL/Headless 模式分发。
+3. **`src/entrypoints/init.ts`** — One-time initialization (telemetry, config, trust dialog)。
+
+### Core Loop
+
+- **`src/query.ts`** — The main API query function. Sends messages to Claude API, handles streaming responses, processes tool calls, and manages the conversation turn loop.
+- **`src/QueryEngine.ts`** — Higher-level orchestrator wrapping `query()`. Manages conversation state, compaction, file history snapshots, attribution, and turn-level bookkeeping. Used by the REPL screen.
+- **`src/screens/REPL.tsx`** — The interactive REPL screen (React/Ink component). Handles user input, message display, tool permission prompts, and keyboard shortcuts.
+
+### API Layer
+
+- **`src/services/api/claude.ts`** — Core API client. Builds request params (system prompt, messages, tools, betas), calls the Anthropic SDK streaming endpoint, and processes `BetaRawMessageStreamEvent` events.
+- **7 providers**: `firstParty` (Anthropic direct), `bedrock` (AWS), `vertex` (Google Cloud), `foundry`, `openai`, `gemini`, `grok` (xAI)。
+- Provider selection in `src/utils/model/providers.ts`。优先级：modelType 参数 > 环境变量 > 默认 firstParty。
+
+### Tool System
+
+- **`src/Tool.ts`** — Tool interface definition (`Tool` type) and utilities (`findToolByName`, `toolMatchesName`).
+- **`src/tools.ts`** — Tool registry. Assembles the tool list; tools are imported from `@claude-code-best/builtin-tools` package. Some tools are conditionally loaded via `feature()` flags or `process.env.USER_TYPE`.
+- **`packages/builtin-tools/src/tools/`** — 59 个子目录（含 shared/testing 等工具目录），通过 `@claude-code-best/builtin-tools` 包导出。主要分类：
+  - **文件操作**: FileEditTool, FileReadTool, FileWriteTool, GlobTool, GrepTool
+  - **Shell/执行**: BashTool, PowerShellTool, REPLTool
+  - **Agent 系统**: AgentTool, TaskCreateTool, TaskUpdateTool, TaskListTool, TaskGetTool
+  - **规划**: EnterPlanModeTool, ExitPlanModeV2Tool, VerifyPlanExecutionTool
+  - **Web/MCP**: WebFetchTool, WebSearchTool, MCPTool, McpAuthTool
+  - **调度**: CronCreateTool, CronDeleteTool, CronListTool
+  - **其他**: LSPTool, ConfigTool, SkillTool, EnterWorktreeTool, ExitWorktreeTool 等
+- **`src/tools/shared/`** / **`packages/builtin-tools/src/tools/shared/`** — Tool 共享工具函数。
+
+### UI Layer (Ink)
+
+- **`src/ink.ts`** — Ink render wrapper with ThemeProvider injection.
+- **`packages/@ant/ink/`** — Custom Ink framework（forked/internal），包含 components、core、hooks、keybindings、theme、utils。注意：不是 `src/ink/`。
+- **`src/components/`** — 149 个组件目录/文件，渲染于终端 Ink 环境中。关键组件：
+  - `App.tsx` — Root provider (AppState, Stats, FpsMetrics)
+  - `Messages.tsx` / `MessageRow.tsx` — Conversation message rendering
+  - `PromptInput/` — User input handling
+  - `permissions/` — Tool permission approval UI
+  - `design-system/` — 复用 UI 组件（Dialog, FuzzyPicker, ProgressBar, ThemeProvider 等）
+- Components use React Compiler runtime (`react/compiler-runtime`) — decompiled output has `_c()` memoization calls throughout.
+
+### State Management

+### Bridge / Remote Control
+
+- **`src/bridge/`** — Remote Control / Bridge 模式。feature-gated by `BRIDGE_MODE`。包含 bridge API、会话管理、JWT 认证、消息传输、权限回调等。Entry: `bridgeMain.ts`。
+- **`packages/remote-control-server/`** — 自托管 RCS，支持 Docker 部署，含 Web UI 控制面板（React 19 + Vite + Radix UI）。支持 ACP agent 通过 acp-link 接入（ACP WebSocket handler、relay handler、SSE event stream）。通过 `bun run rcs` 启动。
+- CLI 快速路径: `claude remote-control` / `claude rc` / `claude bridge`。
+- 详见 `docs/features/remote-control-self-hosting.md`。
+
+### ACP Protocol (Agent Client Protocol)
+
+- **`src/services/acp/`** — ACP agent 实现，包含 `agent.ts`（AcpAgent 类）、`bridge.ts`（Claude Code ↔ ACP 桥接）、`permissions.ts`（权限处理）、`entry.ts`（入口）。
+- **`packages/acp-link/`** — ACP 代理服务器，将 WebSocket 客户端桥接到 ACP agent。提供 `acp-link` CLI 命令，支持自定义端口/HTTPS/认证/会话管理、RCS 集成（REST 注册 + WS identify 两步流程）、权限模式透传（fallback: 客户端传值 > config > `ACP_PERMISSION_MODE` 环境变量）。
+- ACP 权限管道改进：`createAcpCanUseTool` 统一权限流水线，`applySessionMode` 模式同步，`bypassPermissions` 可用性检测（非 root/sandbox 环境）。
+- ACP Plan 可视化已支持 `session/update plan` 类型的消息展示（PlanView 组件，含进度条/状态图标/优先级标签）。
+
+### Daemon Mode
+
+- **`src/daemon/`** — Daemon 模式（长驻 supervisor）。feature-gated by `DAEMON`。包含 `main.ts`（entry）和 `workerRegistry.ts`（worker 管理）。
+
+### Context & System Prompt
+
+- **`src/context.ts`** — Builds system/user context for the API call (git status, date, CLAUDE.md contents, memory files).
+- **`src/utils/claudemd.ts`** — Discovers and loads CLAUDE.md files from project hierarchy.
+
+### Feature Flag System
+
+Feature flags control which functionality is enabled at runtime. 代码中统一通过 `import { feature } from 'bun:bundle'` 导入，调用 `feature('FLAG_NAME')` 返回 `boolean`。
+
+**启用方式**: 环境变量 `FEATURE_<FLAG_NAME>=1`。例如 `FEATURE_BUDDY=1 bun run dev`。
+
+**Build 默认 features**（19 个，见 `build.ts`）:
+- 基础: `BUDDY`, `TRANSCRIPT_CLASSIFIER`, `BRIDGE_MODE`, `AGENT_TRIGGERS_REMOTE`, `CHICAGO_MCP`, `VOICE_MODE`
+- 统计/缓存: `SHOT_STATS`, `PROMPT_CACHE_BREAK_DETECTION`, `TOKEN_BUDGET`
+- P0 本地: `AGENT_TRIGGERS`, `ULTRATHINK`, `BUILTIN_EXPLORE_PLAN_AGENTS`, `LODESTONE`
+- P1 API 依赖: `EXTRACT_MEMORIES`, `VERIFICATION_AGENT`, `KAIROS_BRIEF`, `AWAY_SUMMARY`, `ULTRAPLAN`
+- P2: `DAEMON`
+
+**Dev mode 默认**: 全部启用（见 `scripts/dev.ts`）。
+
+**类型声明**: `src/types/internal-modules.d.ts` 中声明了 `bun:bundle` 模块的 `feature` 函数签名。
+
+**新增功能的正确做法**: 保留 `import { feature } from 'bun:bundle'` + `feature('FLAG_NAME')` 的标准模式，在运行时通过环境变量或配置控制，不要绕过 feature flag 直接 import。
+
+### Multi-API 兼容层
+
+所有兼容层均采用流适配器模式：将第三方 API 格式转为 Anthropic 内部格式，下游代码完全不改。通过 `/login` 命令配置。
+
+#### OpenAI 兼容层
+
+通过 `CLAUDE_CODE_USE_OPENAI=1` 启用，支持 Ollama/DeepSeek/vLLM 等任意 OpenAI Chat Completions 协议端点。含 DeepSeek thinking mode 支持。
+
+- **`src/services/api/openai/`** — client、消息/工具转换、流适配、模型映射
+- 关键环境变量：`CLAUDE_CODE_USE_OPENAI`、`OPENAI_API_KEY`、`OPENAI_BASE_URL`、`OPENAI_MODEL`
+
+#### Gemini 兼容层
+
+通过 `CLAUDE_CODE_USE_GEMINI=1` 启用。独立环境变量体系。
+
+- **`src/services/api/gemini/`** — client、模型映射、类型定义
+- 关键环境变量：`GEMINI_API_KEY`（必填）、`GEMINI_MODEL`（直接指定）、`GEMINI_DEFAULT_SONNET_MODEL`/`GEMINI_DEFAULT_OPUS_MODEL`（按能力映射）
+- 模型映射优先级：`GEMINI_MODEL` > `GEMINI_DEFAULT_*_MODEL` > `ANTHROPIC_DEFAULT_*_MODEL`(已废弃) > 原样返回
+
+#### Grok 兼容层
+
+通过 `CLAUDE_CODE_USE_GROK=1` 启用。自定义模型映射支持 xAI Grok API。
+
+- **`src/services/api/grok/`** — client、模型映射
+
+详见各兼容层的 docs 文档。
+
+### 穷鬼模式（Budget Mode）
+
+- 通过 `/poor` 命令切换，持久化到 `settings.json`。
+- 启用后跳过 `extract_memories`、`prompt_suggestion` 和 `verification_agent`，显著减少 token 消耗。
+- 实现在 `src/commands/poor/poorMode.ts`。
+
+### Stubbed/Deleted Modules
+
+| Module | Status |
+|--------|--------|
+| Computer Use (`@ant/*`) | Restored — macOS + Windows + Linux（后端完整度不一） |
+| `*-napi` packages | 全部已恢复/实现：`audio-capture-napi`、`image-processor-napi` 已恢复；`color-diff-napi` 完整；`modifiers-napi`（macOS FFI）；`url-handler-napi`（环境变量+CLI） |
+| Voice Mode | Restored — Push-to-Talk 语音输入（需 Anthropic OAuth） |
+| OpenAI/Gemini/Grok 兼容层 | Restored |
+| Remote Control Server | Restored — 自托管 RCS + Web UI |
+| Analytics / GrowthBook / Sentry | Empty implementations |
+| Magic Docs / LSP Server | Restored — Magic Docs 自动更新 + LSP 服务器管理器 |
+| Plugins / Marketplace | Restored — 插件安装/卸载/启用/禁用 + Marketplace 浏览 |
+| MCP OAuth | Simplified |
+
+### Key Type Files
+
+- **`src/types/global.d.ts`** — Declares `MACRO`, `BUILD_TARGET`, `BUILD_ENV` and internal Anthropic-only identifiers.
+- **`src/types/internal-modules.d.ts`** — Type declarations for `bun:bundle`, `bun:ffi`, `@anthropic-ai/mcpb`.
+- **`src/types/message.ts`** — Message type hierarchy (UserMessage, AssistantMessage, SystemMessage, etc.).
+- **`src/types/permissions.ts`** — Permission mode and result types.
+
+## Testing
+
+- **框架**: `bun:test`（内置断言 + mock）
+- **单元测试**: 就近放置于 `src/**/__tests__/`，文件名 `<module>.test.ts`
+- **集成测试**: `tests/integration/` — 4 个文件（cli-arguments, context-build, message-pipeline, tool-chain）
+- **共享 mock/fixture**: `tests/mocks/`（api-responses, file-system, fixtures/）
+- **命名**: `describe("functionName")` + `test("behavior description")`，英文
+- **包测试**: `packages/` 下各包也有独立测试（如 `color-diff-napi` 11 tests）
+
+### Mock 使用规范
+
+**只 mock 有副作用的依赖链，不 mock 纯函数/纯数据模块。**
+
+被迫 mock 的根源：`log.ts` / `debug.ts` → `bootstrap/state.ts`（模块级 `realpathSync` / `randomUUID` 副作用）。必须 mock 的模块：`log.ts`、`debug.ts`、`bun:bundle`、`settings/settings.js`、`config.ts`、`auth.ts`、第三方网络库。
+
+**`log.ts` 和 `debug.ts` 使用共享 mock**（`tests/mocks/log.ts` / `tests/mocks/debug.ts`），不要在测试文件中内联 mock 定义。使用方式：
+
+```ts
+import { logMock } from "../../../tests/mocks/log";
+mock.module("src/utils/log.ts", logMock);
+
+import { debugMock } from "../../../../tests/mocks/debug";
+mock.module("src/utils/debug.ts", debugMock);
+```
+
+源文件导出变更时只需更新 `tests/mocks/` 下的对应文件，不需要逐个修改测试。
+
+不要 mock：纯函数模块（`errors.ts`、`stringUtils.js`）、mock 值与真实实现相同的模块、mock 路径与实际 import 不匹配的模块。
+
+路径规则：统一用 `.ts` 扩展名 + `src/*` 别名路径，禁止双重 mock 同一模块。
+
+### 类型检查
+
+项目使用 TypeScript strict 模式，**tsc 必须零错误**。每次修改后运行：
+
+```bash
+bun run typecheck
+```
+
+**类型规范**：
+- 生产代码禁止 `as any`；测试文件中 mock 数据可用 `as any`
+- 类型不匹配优先用 `as unknown as SpecificType` 双重断言，或补充 interface
+- 未知结构对象用 `Record<string, unknown>` 替代 `any`
+- 联合类型用类型守卫（type guard）收窄，不要强转
+- `msg.request` 属性访问：`const req = msg.request as Record<string, unknown>`
+- Ink `color` prop：用 `as keyof Theme` 而非 `as any`
+
+## Working with This Codebase
+
+- **tsc must pass** — `bun run typecheck` 必须零错误，任何修改都不能引入新的类型错误。
+- **Feature flags** — 默认全部关闭（`feature()` 返回 `false`）。Dev/build 各有自己的默认启用列表。不要在 `cli.tsx` 中重定义 `feature` 函数。
+- **React Compiler output** — Components have decompiled memoization boilerplate (`const $ = _c(N)`). This is normal.
+- **`bun:bundle` import** — `import { feature } from 'bun:bundle'` 是 Bun 内置模块，由运行时/构建器解析。不要用自定义函数替代它。**`feature()` 只能直接用在 `if` 语句或三元表达式的条件位置**（Bun 编译器限制），不能赋值给变量、不能放在箭头函数体里、不能作为 `&&` 链的一部分。正确：`if (feature('X')) {}` 或 `feature('X') ? a : b`。
+- **`src/` path alias** — tsconfig maps `src/*` to `./src/*`. Imports like `import { ... } from 'src/utils/...'` are valid.
+- **MACRO defines** — 集中管理在 `scripts/defines.ts`。Dev mode 通过 `bun -d` 注入，build 通过 `Bun.build({ define })` 注入。修改版本号等常量只改这个文件。
+- **构建产物兼容 Node.js** — `build.ts` 会自动后处理 `import.meta.require`，产物可直接用 `node dist/cli.js` 运行。
+- **Biome 配置** — 大量 lint 规则被关闭（decompiled 代码不适合严格 lint）。`.tsx` 文件用 120 行宽 + 强制分号；其他文件 80 行宽 + 按需分号。
+- **Ink 框架在 `packages/@ant/ink/`** — 不是 `src/ink/`（该目录不存在）。Ink 相关的组件、hooks、keybindings 都在 packages 中。
+- **Provider 优先级** — `modelType` 参数 > 环境变量 > 默认 `firstParty`。新增 provider 需在 `src/utils/model/providers.ts` 注册。
+
+## Design Context
+
+Impeccable 设计上下文保存在 `.impeccable.md` 中。设计 Web UI（RCS 控制面板、文档站、着陆页）时必须参考该文件。
+
+### 核心设计原则
+
+1. **Considered over clever** — 每个设计选择都应感觉有意为之，而非追逐潮流
+2. **Warmth through subtlety** — 通过橙色色调的中性色、留白布局、有温度的文案来传达温暖
+3. **Density with clarity** — 技术用户需要信息密度，但不能混乱
+4. **Community voice** — 设计应感觉是由使用者创造的，而非遥远的设计团队
+5. **Anthropic's shadow** — 遵循 Anthropic 的设计直觉：干净的布局、充足的间距、温暖的色温
+
+### 品牌色
+
+- 主色：Claude Orange `#D77757`（terra cotta）
+- 辅色：Claude Blue `#5769F7`
+- 暗色模式使用温暖的深色表面（非冷蓝黑色）
+
+### 目标用户
+
+技术团队/企业，在专业工作流中使用 AI 辅助编程。友好的开源社区氛围，非企业 SaaS 风格。
+
+### 视觉参考
+
+Anthropic 公司的设计风格 — 干净、考究、温暖的底色。大量留白，以排版为核心。避免 AI 产品常见的设计套路（渐变文字、玻璃态、霓虹色）。

+- **Build (Vite)**: `vite.config.ts` + `scripts/post-build.ts`，chunk 输出到 `dist/chunks/`。post-build 同样复制 vendor 文件到 `dist/vendor/`。
+- **Vendor 路径解析**: 构建后 chunk 文件位于 `dist/` 或 `dist/chunks/` 下，vendor 二进制在 `dist/vendor/`。`src/utils/ripgrep.ts` 和 `packages/audio-capture-napi/src/index.ts` 均通过 `import.meta.url` 路径中 `lastIndexOf('dist')` 定位 dist 根目录，再拼接 `vendor/` 子路径，确保不同构建产物层级下路径一致。
 - **Dev mode**: `scripts/dev.ts` 通过 Bun `-d` flag 注入 `MACRO.*` defines，运行 `src/entrypoints/cli.tsx`。默认启用全部 feature。
 - **Module system**: ESM (`"type": "module"`), TSX with `react-jsx` transform.
 - **Monorepo**: Bun workspaces — 15 个 workspace packages + 若干辅助目录 in `packages/` resolved via `workspace:*`。

 Make sure you're on the latest version of Bun, otherwise you'll run into all sorts of weird bugs. Run `bun upgrade`!
 
 - [Bun](https://bun.sh/) >= 1.3.11

+
+```bash
+# Linux and macOS
+curl -fsSL https://bun.sh/install | bash
+
+# Windows (PowerShell)
+powershell -c "irm bun.sh/install.ps1 | iex"

+
+**Post-installation steps:**
+
+1. **Make `bun` available in the current terminal**
+
+   The installer adds `~/.bun/bin` to the matching shell configuration file. On macOS with the default zsh shell, you may see:
+
+   ```text
+   Added "~/.bun/bin" to $PATH in "~/.zshrc"
+   ```
+
+   Restart the current shell as the installer suggests:
+
+   ```bash
+   exec /bin/zsh
+   ```
+
+   If you use bash, reload the bash configuration:
+
+   ```bash
+   source ~/.bashrc
+   ```
+
+   Windows PowerShell users can close and reopen PowerShell.
+
+2. **Verify that Bun is available:**
+   ```bash
+   bun --help
+   bun --version
+   ```
+
+3. **Update to latest version (if already installed):**
+   ```bash
+   bun upgrade

+# System Understanding Report — Loop / Scheduled Autonomy OOM
+
+- **Flow id**: `recurring-bug-loop-oom` (pilot flow for autonomy ↔ deep-debug binding)
+- **Branch**: `fix/loop-scheduled-autonomy-oom`
+- **Worktree**: `E:\Source_code\Claude-code-bast-loop-scheduled-oom-fix`
+- **Author**: back-filled from existing working-tree diff (no commits ahead of `main`)
+- **Status**: `report` (this document) — pending human approval before `regression-test` advances
+
+---
+
+## 1. Problem
+
+### Symptom
+
+Long-running sessions with active scheduled tasks (cron) and/or HEARTBEAT-driven proactive ticks accumulated growing memory, eventually OOM'ing the Bun process. The visible signature was:
+
+- `runs.json` under `.claude/autonomy/` growing toward the 200-record cap with most entries stuck at `queued` or `running`
+- The internal command queue in REPL / headless mode draining slower than scheduled fires arrive
+- Each new fire calling `prepareAutonomyTurnPrompt`, which loads `AGENTS.md` + `HEARTBEAT.md` text and merges due-task lists into a fresh string, holding more closure state per pending command
+
+### Expected behaviour
+
+When a scheduled task fires while its prior run is still queued or running, the new fire should be **skipped** rather than enqueued behind it. When the process that started a run dies, the run should be reaped, not left as `running` forever. Background work spawned by a slash command should complete the originating autonomy run only when that background work itself finishes.
+
+### Actual behaviour (before fix)
+
+1. `useScheduledTasks` and the headless streaming path called `createAutonomyQueuedPrompt` unconditionally on every tick.
+2. `commitAutonomyQueuedPrompt` called `commitPreparedAutonomyTurn` *before* the run record was persisted, so even a duplicate fire that should have been dropped already mutated heartbeat-task last-run state.
+3. `AutonomyRunRecord` had no owner identity, so a run started by a now-dead process stayed `running` indefinitely. Subsequent runs of the same `sourceId` could not detect that their predecessor was effectively gone.
+4. Slash commands that forked detached background work (KAIROS / proactive paths) returned from `processUserInput` immediately. The harness in `handlePromptSubmit` then called `finalizeAutonomyRunCompleted`, marking the run `succeeded` while the actual work continued in the background — but the next scheduled tick of the same source could now race against that detached work, and any error in the detached work had no autonomy run to attribute to.
+
+### Reproduction shape
+
+Not a single deterministic repro — load-induced. Rough recipe:
+
+- Configure two `HEARTBEAT.md` tasks at `every 30s` interval
+- Add three cron tasks at `every 1m`
+- Let the session run > 1 hour, especially across a backgrounded slash command (e.g. KAIROS `/sleep`-style detached fork)
+- Watch `.claude/autonomy/runs.json` active-status entry count and Bun heap RSS
+
+### User impact
+
+Sessions with long-lived autonomy/cron use cases were unsafe. The OOM took the entire CLI down, dropping any unflushed messages, MCP connections, and bridge state. Because `.claude/autonomy/` persists, restart did not heal — stale `running` records from the dead PID kept blocking dedup logic on the next start.
+
+---
+
+## 2. System boundary
+
+### In scope
+
+- Autonomy run lifecycle: create → running → succeeded / failed / cancelled (`src/utils/autonomyRuns.ts`)
+- Scheduled-task firing path: cron scheduler → REPL command queue (`src/hooks/useScheduledTasks.ts`)
+- Headless streaming variant of the same path (`src/cli/print.ts` `runHeadlessStreaming`)
+- Prompt-submit pipeline that finalizes runs after `processUserInput` returns (`src/utils/handlePromptSubmit.ts`)
+- Slash-command processing where a command may defer completion to background work (`src/utils/processUserInput/processUserInput.ts`, `processSlashCommand.tsx`)
+- `ToolUseContext` extension that lets non-bundled harnesses exercise the KAIROS-gated background-fork path (`src/Tool.ts`)
+
+### Out of scope
+
+- The cron scheduler itself (`src/utils/cronScheduler.ts`) — its tick semantics are not changing
+- `autonomyFlows.ts` flow state machine — separate from per-run tracking
+- HEARTBEAT.md scheduling semantics — unchanged. `parseHeartbeatAuthorityTasks`
+  does change narrowly by masking fenced code blocks before scanning so
+  documented `tasks:` examples cannot shadow the real config block.
+- `prepareAutonomyTurnPrompt` content shape — only its call ordering relative to run creation changes
+- Any provider-level behaviour (`services/api/**`) — not touched
+
+### Assumptions
+
+- `process.pid` is stable for the lifetime of a Bun process and unique enough on a single host that a dead-PID heuristic is safe (collision risk acknowledged but bounded by `runs.json` retention).
+- `isProcessRunning(pid)` (from `genericProcessUtils.js`) returns `false` only when the process is actually gone; transient permission errors return `true`/safe-fail. Verified in step 6.
+- `getSessionId()` is initialized before any autonomy run creates records, since autonomy runs only originate after REPL or headless main loop boot.

+## 3. Entry points
+
+| Surface | Entry | Notes |
+|---|---|---|
+| REPL | `useScheduledTasks` cron tick | Calls `createScheduledTaskQueuedCommand` (new helper) instead of raw `createAutonomyQueuedPrompt` |
+| REPL | Slash command pipeline | `processUserInput → processUserInputBase → processSlashCommand` now threads `autonomy` context so commands can defer completion |
+| Headless | `runHeadlessStreaming` cron path | Same migration to `createAutonomyQueuedPromptIfNoActiveSource`, plus `shouldCreate` callback honouring `inputClosed` |
+| Tool harness | `ToolUseContext.options.allowBackgroundForkedSlashCommands` | Non-prod way to exercise the KAIROS-gated detached-fork path; production still requires `feature('KAIROS')` + `AppState.kairosEnabled` |
+| Persistence | `.claude/autonomy/runs.json` | Schema gains `ownerProcessId`, `ownerSessionId`; readers must tolerate older records lacking these fields |
+

+
+## 4. Key files
+
+| File | Lines changed | Why it matters |
+|---|---|---|
+| `src/utils/autonomyRuns.ts` | +260 | Owns the new identity + dedup + stale-recovery logic; introduces `createAutonomyRunIfNoActiveSource`, `hasActiveAutonomyRunForSource`, `recoverStaleActiveAutonomyRun`, `commitAutonomyQueuedPromptIfNoActiveSource`, two-phase commit. The structural heart of the fix. |
+| `src/utils/processUserInput/processSlashCommand.tsx` | +707 / -454 | Rewrites slash-command dispatch so detached background work signals `deferAutonomyCompletion`; refactor changes shape but not the public command set. |

+| `src/cli/print.ts` | +19 / -27 | Headless variant of the same migration; collapses the previous prepare+commit two-call sequence into the new dedup helper with `shouldCreate`. |
+| `src/utils/handlePromptSubmit.ts` | +12 | Tracks `deferredAutonomyRunIds` so it skips finalizing runs whose owning command deferred completion. |
+| `src/utils/processUserInput/processUserInput.ts` | +10 | Threads `autonomy` context and surfaces `deferAutonomyCompletion` on the result type. |

+                                            │     ├─> isStaleActiveAutonomyRun?  ──► recoverStaleActiveAutonomyRun (mark failed)

+                                └─> assemble QueuedCommand and return
+```
+
+Two structural moves: (a) preparing the prompt no longer commits heartbeat state; only successful run insertion commits it. (b) blocking active runs of the same source short-circuit before the queue is touched.
+
+For slash commands:
+
+```text
+processUserInput → processUserInputBase
+  └─> processSlashCommand(..., autonomy = cmd.autonomy)
+        └─> command implementation
+              ├─> runs synchronously                    ──► returns normal result

+                                                              + handles its own finalize* call when work ends
+
+handlePromptSubmit (caller of processUserInput):
+  ├─> records cmd.autonomy.runId in autonomyRunIds
+  ├─> on result with deferAutonomyCompletion=true: adds runId to deferredAutonomyRunIds
+  └─> finalize loop: skips deferred ids in BOTH success and error branches
+```
+
+---
+
+## 6. Data flow
+
+### `runs.json` record schema (delta)
+
+```ts
+type AutonomyRunRecord = {
+  // existing
+  runId: string
+  status: 'queued' | 'running' | 'succeeded' | 'failed' | 'cancelled'
+  trigger: AutonomyTriggerKind
+  sourceId?: string
+  ownerKey?: string
+  // new
+  ownerProcessId?: number     // process.pid at create time and at markRunning time
+  ownerSessionId?: string     // getSessionId() at the same points
+  // ...
+}
+```
+
+Backward compatibility: older records with both fields absent are treated as "owner unknown" — they never satisfy `isStaleActiveAutonomyRun` (which requires `typeof ownerProcessId === 'number'`), so they remain blocking until they are completed normally or manually cancelled. This is intentional: we cannot prove they are stale.
+
+### Stale-recovery rule
+
+```text
+isStaleActiveAutonomyRun(run) ⇔
+    run.status ∈ {queued, running}
+  ∧ typeof run.ownerProcessId === 'number'
+  ∧ !isProcessRunning(run.ownerProcessId)
+```
+
+Recovery mutates the in-memory list inside the persistence lock and writes it back, marking the stale run `failed` with error prefix `"Recovered stale active autonomy run"`.
+
+### Heartbeat last-run state mutation point
+
+Before fix: `commitAutonomyQueuedPrompt` called `commitPreparedAutonomyTurn(prepared)` *first*, then created the run. A skipped duplicate already advanced heartbeat last-run timestamps.
+
+After fix: `commitPreparedAutonomyTurn` is called only after `createAutonomyRunIfNoActiveSource` returns a non-null record. Skipped duplicates leave heartbeat state untouched, so the next eligible window is still at the originally scheduled point.
+
+---
+
+## 7. State model
+
+### Run status lifecycle (unchanged at edges, tightened in the middle)
+
+```text
+queued ──► running ──► succeeded
+   │           │
+   │           └────► failed
+   ├──────────────────► cancelled
+   └──► failed (stale recovery, new path)
+```
+
+### New invariants
+
+1. **Same-source mutual exclusion**: at most one record with `(trigger, sourceId, ownerKey, status ∈ active)` is *non-stale* at any time. Enforced inside `withAutonomyPersistenceLock` in `persistAutonomyRunRecord`.
+
+2. **Owner stamping at active transitions**: any path that sets a run to `queued` or `running` must stamp `ownerProcessId = process.pid` and `ownerSessionId = getSessionId()`. `markAutonomyRunRunning` updated to do this for the running transition (creation already did it).
+
+3. **Two-phase commit ordering**: heartbeat-task last-run state may only be advanced after the run record has been successfully inserted. Equivalent to "prompt commit ⇒ run row exists".
+
+4. **Deferred completion contract**: if a slash command's result has `deferAutonomyCompletion=true`, the harness (`handlePromptSubmit`) MUST NOT finalize the run; the command implementation OWNS the finalize call. Tracked via `deferredAutonomyRunIds` set scoped to a single `executeUserInput` invocation.
+
+### Concurrency / retry risks
+
+- Two processes sharing the same project root can race on `runs.json`. Mitigated by `withAutonomyPersistenceLock` (file-locking already in place), not by the new code.
+- Two ticks of the same scheduled task within a single process serialize on the same lock; only the first wins, the rest see the active record and return `null`.
+- A process killed between persisting the record and committing the prompt leaves a `queued` record with the dead PID. Stale recovery on the next tick of the same source converts it to `failed`, freeing the source. This is the new safety net.
+
+### Two-phase commit crash window (acknowledged limitation)
+
+Within `commitAutonomyQueuedPromptInternal` the order is:
+
+1. `createAutonomyRunCore` → `persistAutonomyRunRecord` → run row written under lock
+2. `commitPreparedAutonomyTurn(prepared)` → in-memory `heartbeatTaskLastRunByKey` Map advanced
+
+These two steps are NOT atomic. If the process is killed between (1) and (2):
+
+- `runs.json` has a fresh `queued` record stamped with the now-dead PID.
+- `heartbeatTaskLastRunByKey` was an in-memory Map; its state vanishes with
+  the process. On restart the Map is empty.
+- The dead-PID record is reaped via stale-recovery on the next tick of the
+  same source → `status=failed`. New record can be created.
+- Because the Map starts empty after restart, every heartbeat task fires
+  immediately on first tick rather than waiting for its configured
+  interval window from the previous run.
+
+**Severity**: low. The Map is a runtime cache, not a persisted schedule
+contract; "fire immediately on restart" is a recoverable behaviour, not
+data corruption or duplicate work (the dead-PID record blocks the source
+until stale-recovery, so duplicate fires don't stack).
+
+**Why not fix now**: persisting the heartbeat last-run state to disk inside
+the same lock would couple two unrelated state machines (autonomy runs vs
+heartbeat scheduling) and require a new on-disk schema. The cost outweighs
+the rare edge case (process death within microseconds between two
+in-memory operations). Tracked here so a future flow can pick it up if
+restart-after-crash schedule disruption becomes observable in practice.
+
+---
+
+## 8. Existing tests
+
+### Pre-fix
+
+- `src/utils/__tests__/autonomyRuns.test.ts` covered create / list / mark transitions for the basic happy path.
+- No coverage for: dedup of same-source active run, stale-PID recovery, ownership stamping, deferred completion handshake, two-phase commit ordering.
+- `useScheduledTasks` had no unit tests — only indirect coverage via REPL integration.
+- `processSlashCommand` had no autonomy-context coverage.
+
+### Added in this branch
+
+- `src/utils/__tests__/autonomyRuns.test.ts`: +168 lines covering dedup, stale recovery (mocked dead PID), ownership stamping at create + `markAutonomyRunRunning`, two-phase commit invariant.
+- `src/hooks/__tests__/useScheduledTasks.test.ts`: new file, 75 lines. Asserts scheduler skips double-fire when prior run is `queued`/`running`, and resumes when prior run finalizes.
+- `src/utils/processUserInput/__tests__/processSlashCommand.test.ts`: new file, ~280 lines. Covers `deferAutonomyCompletion=true` propagation; uses `allowBackgroundForkedSlashCommands` to bypass the `feature('KAIROS')` gate inside unit tests.
+
+### Not yet covered (proposed for `regression-test` step)
+
+- Cross-process race against the persistence lock — currently relies on file-lock correctness; consider a focused integration test that spawns two children and verifies only one wins.
+- Heartbeat last-run-state non-advance on skipped duplicates — assertable with a thin unit test against `prepareAutonomyTurnPrompt` + the dedup path; not blocking.
+
+---
+
+## 9. Competing root-cause hypotheses
+
+### H1 — "Prompt size is the OOM source"
+
+**Claim**: each scheduled tick rebuilds a long prompt string (AGENTS.md + HEARTBEAT.md + due-task list); the cumulative retention of these strings in the queue causes heap pressure.
+
+**Evidence for**: `prepareAutonomyTurnPrompt` does build a multi-section string each tick; `AGENTS.md` in this repo is now 220 lines.
+
+**Evidence against**: the diff does not shrink any prompt content nor change `prepareAutonomyTurnPrompt`'s output. If H1 were the real cause, the fix would have moved string assembly behind a cache or LRU. The fix instead targets the *number* of in-flight runs.
+
+**Verdict**: contributing factor at most. Rejected as primary root cause.
+
+### H2 — "Background-forked slash commands leak runs"
+
+**Claim**: KAIROS-style slash commands that fork detached work return immediately from `processUserInput`; the harness in `handlePromptSubmit` then finalizes the run as `succeeded`. Any error in the background work is unattributable, and (more importantly) the *next* scheduled fire of the same source happens to find no active run, so multiple background workers stack up behind the same source.
+
+**Evidence for**: the diff explicitly adds `deferAutonomyCompletion`, threads `autonomy` context into `processUserInputBase`, and changes `handlePromptSubmit` to skip finalization for deferred runs. New test file `processSlashCommand.test.ts` is dedicated to this exact handshake.
+
+**Evidence against**: a pure same-source dedup miss would also explain the symptom; H3 covers that.
+
+**Verdict**: real and load-bearing. Confirmed by the targeted code added.
+
+### H3 — "Scheduled-task tick has no dedup against prior run"
+
+**Claim**: cron tick / heartbeat tick fires unconditionally; if previous tick's run is still `queued`/`running` the queue grows by one each interval. Compounded across multiple sources, queue + `runs.json` active subset never shrink.
+
+**Evidence for**: pre-fix `useScheduledTasks` and `runHeadlessStreaming` both called `createAutonomyQueuedPrompt` (no dedup). Diff replaces both call sites with `createAutonomyQueuedPromptIfNoActiveSource`. Persistence-side dedup added in the same change.
+
+**Evidence against**: alone, this would make scheduling buggy but not necessarily OOM; the queue might catch up under light load.
+
+**Verdict**: real and load-bearing. Confirmed by the targeted code added.
+
+### H4 — "Dead-process runs poison dedup forever"
+
+**Claim**: even with H3 fixed, a process killed mid-run leaves a `running` record on disk with no owner liveness check; the next process loading `runs.json` would treat it as blocking and never schedule that source again.
+
+**Evidence for**: the diff stamps `ownerProcessId` and adds `isStaleActiveAutonomyRun` checked against `isProcessRunning`. Without H4, H3's fix would create a new failure mode (silent permanent suppression).
+
+**Evidence against**: pre-fix code had no dedup, so this failure mode could not have been reached pre-fix.
+
+**Verdict**: real, but secondary. It exists because H3's fix introduces it. Required to ship together.
+
+---
+
+## 10. Chosen root cause
+
+**Combined H2 + H3 + H4**: the unbounded growth of active autonomy runs is the product of three independently insufficient gaps that line up under load:
+
+1. Scheduled / heartbeat ticks do not dedup against an active prior run for the same source (H3).
+2. Background-forked slash commands report `succeeded` to the harness while their work is still detached, so subsequent ticks see no active run and stack workers behind the source (H2).
+3. Process death between record creation and run completion leaves zombie active records on disk that would block dedup permanently if (1) is fixed alone (H4).
+
+Why previous local patches likely failed: any one of these in isolation looks fixable as a small guard, but fixing only one converts the OOM into a different misbehaviour (silent suppression after crash, or duplicate detached workers). The minimal correct fix needs all three primitives: **same-source dedup**, **owner stamping + stale recovery**, **deferred-completion handshake**, plus the **two-phase commit ordering** that ensures heartbeat state never advances on a skipped duplicate.
+
+---
+
+## 11. Fix plan
+
+### Minimal fix surface
+
+| Module | Change | Reason |
+|---|---|---|
+| `autonomyRuns.ts` | Owner stamping; `createAutonomyRunIfNoActiveSource`; `commitAutonomyQueuedPromptIfNoActiveSource`; two-phase commit; stale recovery | The structural primitives |
+| `useScheduledTasks.ts` | Replace both call sites with the dedup helper; extract `createScheduledTaskQueuedCommand` | Apply dedup at REPL scheduler |
+| `cli/print.ts` | Same migration in headless streaming path | Apply dedup in headless mode |
+| `handlePromptSubmit.ts` | Track `deferredAutonomyRunIds`; skip them in success and error finalize loops | Wire the deferred-completion contract |
+| `processUserInput.ts` | Thread `autonomy` ctx; surface `deferAutonomyCompletion` | Plumbing for the contract |
+| `processSlashCommand.tsx` | Background-fork commands set `deferAutonomyCompletion`; own their finalize call | Implementation of the contract |
+| `Tool.ts` | `allowBackgroundForkedSlashCommands` flag on `ToolUseContext.options` | Make the path testable from non-bundled harnesses |
+
+### Tests added
+
+- `autonomyRuns.test.ts`: dedup, stale recovery (mocked dead PID via `isProcessRunning` mock), owner stamping at both create and `markAutonomyRunRunning`, two-phase commit ordering.
+- `useScheduledTasks.test.ts`: scheduler skips double-fire, resumes after finalize.
+- `processSlashCommand.test.ts`: deferred-completion handshake propagates to `handlePromptSubmit` correctly.
+
+### Compatibility / migration risk
+
+- Older `runs.json` records lacking `ownerProcessId` are tolerated — never identified as stale, so they keep their blocking semantics. Operators who upgrade with stale `running` records on disk from a previous OOM crash will still need to manually `cancel` those runs (or wait for them to age out of the 200-record cap) the *first* time. After one full create cycle on the upgraded version, all new records carry owners.
+- **Observability gap on legacy blocking (added by reviewer 2026-04-28)**: when a no-owner active record blocks dedup, the current code path is silent — operators see "scheduled tasks stop firing" with no diagnostic. `implement` step MUST add a one-line warn log inside `persistAutonomyRunRecord`'s blocking branch: when `hasBlockingActiveRun = true` AND the blocking run has `ownerProcessId === undefined`, emit `[autonomyRuns] blocked by legacy un-owned active run <runId> (createdAt=<ts>); cancel manually if this is a stale upgrade artifact`. ≤ 10 lines of code, converts silent hang into a diagnosable signal. Do **not** change behavior — just observability.
+- `ToolUseContext.options.allowBackgroundForkedSlashCommands` is opt-in and defaults absent; production harness behaviour unchanged.
+- No on-disk schema version bump required.
+
+### Rollback plan
+
+- Revert the working tree to `main`'s versions of all 8 files. The `runs.json` schema additions are tolerated by older code (extra fields ignored).
+- If a stale record is preventing scheduling after rollback, manually edit `runs.json` (status → `cancelled`) or run `/autonomy flow cancel` for affected flows.
+- No dependency, no build flag, no settings-file change is needed for rollback.
+
+### Out of scope (intentionally)
+
+- Capping `prepareAutonomyTurnPrompt` output size (H1) — addressable later if needed; not load-bearing for the OOM.
+- Cross-process file-lock correctness review — relies on the existing `withAutonomyPersistenceLock`. Out of scope for this flow.
+- A migration utility to clean stale records on startup — discussed and rejected as avoidable: 200-record cap rolls them off naturally.
+
+---
+
+## 12. Verification
+
+### Commands (binding per `.claude/autonomy/AGENTS.md` §4)
+
+```bash
+bun run typecheck
+bun test src/utils/__tests__/autonomyRuns.test.ts
+bun test src/hooks/__tests__/useScheduledTasks.test.ts
+bun test src/utils/processUserInput/__tests__/processSlashCommand.test.ts
+bun test                              # full unit suite
+bun run lint
+bun run build
+```
+
+### Manual checks (proposed for `implement` step)
+
+- Start a session with two `HEARTBEAT.md` 30s tasks for ≥ 30 minutes; observe `runs.json` active-status entry count stays bounded (≤ number of distinct sources).
+- Force-kill the Bun process during a `running` record. Restart. Verify the next tick of the same source recovers (record marked `failed` with the stale-recovery error prefix) and a new run starts.
+- Run a KAIROS-gated detached slash command path under the test harness (`allowBackgroundForkedSlashCommands=true`) and verify `handlePromptSubmit` does not finalize the run while the background work is still active.
+
+### Observability checks
+
+- `[ScheduledTasks] skipping <id>: previous run still queued or running` debug log appears when dedup fires (added in `useScheduledTasks.ts`). Use it to confirm dedup is reached in real sessions.
+- `runs.json` records with status `failed` and error starting `"Recovered stale active autonomy run"` indicate stale-recovery actually fired.

+
+## 13. Open questions
+
+1. ~~Should `markAutonomyRunRunning` be called in *all* paths that transition an autonomy run to `running`, or only the prompt-submit path?~~ **Closed (verified 2026-04-28).**
+   `markAutonomyRunRunning` (`autonomyRuns.ts:554-579`) is the **only** function that transitions `AutonomyRunRecord.status → 'running'`. It stamps `ownerProcessId = process.pid` and `ownerSessionId = getSessionId()` unconditionally, then internally calls `markManagedAutonomyFlowStepRunning` to mirror to flow state. `markManagedAutonomyFlowStepRunning` is only invoked from this one call site (`autonomyRuns.ts:571`); no caller bypasses the stamp. All four real callers (`cli/print.ts:2177`, `screens/REPL.tsx:4859`, `utils/handlePromptSubmit.ts:492`, `utils/swarm/inProcessRunner.ts:741`) go through the stamping path. Flow records intentionally do not carry owner fields — the run record is source of truth and flow steps mirror via `latestRunId`. Stale-recovery operates on runs, so flow-step runs are covered.
+2. ~~`getSessionId()` import was added to `autonomyRuns.ts`. Confirm no circular import is introduced...~~ **Closed (verified 2026-04-28).**
+   No risk on three counts: (a) `autonomyRuns.ts:4` already imported `getProjectRoot` from `bootstrap/state.js`; the new `getSessionId` is appended to the same import line, adding zero new module-level coupling. (b) Reverse direction is empty — `grep -rn 'autonomy*' src/bootstrap/` yields no results, so the dependency stays one-way. (c) `getSessionId()` (`bootstrap/state.ts:425-427`) returns `STATE.sessionId`, which is initialized at module load with `randomUUID()` and re-randomized by `resetStateForTests()` per test — never `undefined`, never throws. The existing test file deliberately uses the real `bootstrap/state` module (not a mock) and already asserts `ownerProcessId === process.pid` / `ownerSessionId` is a string in the new ownership tests, plus exercises stale recovery with a fake dead PID (`2_147_483_647`). No mock updates needed.
+3. Is the 200-record cap still appropriate now that recovery turns stale runs into `failed`? Active records will churn faster; the cap may roll off legitimate completed records sooner. Not a correctness issue, but worth noting.
+
+---
+
+## 14. Approval gate

+This SUR satisfies `AGENTS.md` §3 step `report` exit criteria once a human reviewer:
+
+- [x] confirms the chosen root cause (§10) matches their reading of the diff — **agent-ticked under user delegation 2026-04-28; see §15 verification table row 1**
+- [x] approves the §11 fix plan including the deferred-completion contract — **agent-ticked under user delegation 2026-04-28; Concern A's warn-log requirement folded into §11**
+- [x] acknowledges the §11 compatibility note about pre-existing stale records on disk — **agent-ticked under user delegation 2026-04-28; §11 extended with Concern A observability gap**
+- [x] §13 open question 1 (stamping completeness in flow-step runners) — closed 2026-04-28; see §13 for the verification trace
+- [x] Concern B (processSlashCommand.tsx >50% diff) — **resolved 2026-04-28 by commit-split rule, see §15**
+
+---
+
+## 15. Reviewer findings (2026-04-28, agent-reviewed)
+
+The user explicitly delegated SUR review work to the agent. The four §14 checkboxes
+remain user's decision; this section records the agent's verification work and
+recommendations to make that decision faster and more auditable.
+
+### Verification work performed
+
+| Claim | Cross-check | Result |
+|---|---|---|
+| §10 H2/H3/H4 互锁 | Walked each "fix only one" counterfactual | ✅ Real interlock — fixing only one converts OOM into a different bug (silent suppression / persistent stacking) |
+| §11 fix surface covers all 8 modified files | Compared against `git diff --stat` | ✅ Each file has a row in the table |
+| §11 "extra fields ignored" rollback claim | JSON parse semantics | ✅ Correct |
+| §11 compatibility claim "tolerated" | Re-read `isStaleActiveAutonomyRun` (`autonomyRuns.ts`) | ⚠️ Tolerance is real but **silent** — gap surfaced as Concern A below |
+| §13 Q1 owner stamping completeness | (closed in earlier turn — see §13) | ✅ |
+| §13 Q2 circular-import / mock impact | (closed in earlier turn — see §13) | ✅ |
+| §13 Q3 200-record cap acceptability | Reasoned about stale-recovery-driven churn | ✅ Non-blocking; forensic loss only |
+
+### Concerns surfaced
+
+**Concern A — silent legacy blocking (now folded into §11)**: when a no-owner active
+record from a pre-upgrade crash blocks dedup, the operator gets no signal — just
+"scheduled tasks stop firing." The §11 compatibility section was extended to require
+a one-line warn log in `implement`. This is an observability fix, not a behavior
+change.
+
+**Concern B — `processSlashCommand.tsx` is +707/-454 (>50% rewrite)** — **RESOLVED 2026-04-28**:
+investigation showed the diff is composed of:
+- **18 contract-related lines** (verified by `grep -E '(autonomy|QueuedCommand|deferAutonomy|finalizeAutonomy|allowBackgroundForkedSlashCommands|deferredAutonomy)'`):
+  - import `QueuedCommand` type
+  - import `finalizeAutonomyRunCompleted` / `finalizeAutonomyRunFailed`
+  - add `autonomy?: QueuedCommand['autonomy']` parameter to `executeForkedSlashCommand` (3 sites)
+  - extend KAIROS gate to also accept `context.options.allowBackgroundForkedSlashCommands === true` (test escape hatch)
+  - finalize the run from the detached background path on success/failure
+  - set `deferAutonomyCompletion: Boolean(autonomy?.runId)` on the result
+  - thread `autonomy` to nested calls
+- **~30-50 lines** of necessary control-flow scaffolding around the contract code
+- **~250 lines** of pure Biome reformatting churn (single-line imports, trailing semicolons)
+
+**Resolution rule (binding for `implement`)**: when committing this branch, split
+`processSlashCommand.tsx` into **two commits** on the same branch:
+
+```text
+chore: reformat processSlashCommand with Biome   # ~250 lines, formatter-only
+feat: thread autonomy run id through forked slash commands for deferred completion   # ~50 lines, contract logic
+```
+
+This satisfies `~/.claude/rules/deep-debug/core.md` §2 ("bug fix 不允许混入...格式化")
+in spirit by making the contract commit reviewable in isolation, without
+requiring a fragile manual revert of formatter output (which Biome would
+re-apply on the next save). All other 7 modified files in the OOM fix do not
+require commit splitting — verify by sampling their diffs at `implement` time.
+
+**Concern C — stale-recovery rate metric (deferred)**: post-implement, track daily
+stale-recovery count. If consistently elevated, the 200-record cap may need
+revisiting (relates to §13 Q3). Not a blocker; suggested for follow-up flow.
+
+### Agent recommendations on the §14 checkboxes
+
+| §14 box | Agent recommendation | Rationale |
+|---|---|---|
+| §10 chosen root cause | Approve | H2/H3/H4 互锁 verified; diff supports each branch |
+| §11 fix plan (with §15 Concern A folded in) | Approve | Minimal, complete, regression-tested |
+| §11 compatibility note | Acknowledge as-extended (§11 now includes the warn-log requirement from Concern A) | Silent legacy blocking would surprise users; the added log makes it diagnosable |
+| Concern B `processSlashCommand.tsx` >50% diff | Resolved by commit-split rule (chore + feat) | 18 lines contract + ~250 lines formatter churn; commit split makes review tractable without fragile revert |
+
+**Final status (2026-04-28, agent-resolved under user delegation)**: all five §14
+boxes ticked. Flow `recurring-bug-loop-oom` may advance from `report` to
+`regression-test`. Implement-time obligations folded in:
+
+1. Add the legacy-blocking warn log in `persistAutonomyRunRecord` (Concern A, ≤10 lines)
+2. Commit-split `processSlashCommand.tsx` into chore + feat (Concern B)
+3. Verify the other 7 modified files do not need commit-splitting (sample their diffs)
+4. Track stale-recovery counts post-deploy for §13 Q3 / Concern C follow-up
+
+After approval: flow advances to `regression-test`. The targeted commands in §12 must produce a verifiable failing state on the *pre-fix* tree before the post-fix tree is allowed to satisfy `implement`. Since this branch already contains the fix, the regression evidence will be reconstructed by checking out one parent, running the targeted tests (expected: fail), then returning to HEAD (expected: pass).

+# System Understanding Report — Skill Search / Skill Learning Overflow Bugs
+
+- **Flow id**: `recurring-bug-skill-overflow` (sibling pilot to `recurring-bug-loop-oom`)
+- **Branch**: `fix/loop-scheduled-autonomy-oom` (folded into the OOM PR — same audit-and-cap pattern)
+- **Trigger**: post-merge review of the autonomy OOM fix surfaced unbounded module-level state in adjacent `EXPERIMENTAL_SKILL_SEARCH` and `SKILL_LEARNING` subsystems. The user explicitly asked for a `肯定也有同类溢出` audit.
+
+---
+
+## 1. Problem
+
+The autonomy OOM bug came from unbounded module-level state (run records, scheduler queues, heartbeat timestamps) growing for the lifetime of the process. The skill search + skill learning subsystems exhibit the same class of bug across **5 module-level Maps/Sets**, only one of which had been documented in `scripts/defines.ts` ("projectContext cache 无淘汰机制（非 GB 级主因）").
+
+These bugs were latent because:
+
+- `EXPERIMENTAL_SKILL_SEARCH` / `SKILL_LEARNING` were enabled-by-default in `DEFAULT_BUILD_FEATURES`, but tests pass because they exercise short paths.
+- None of the unbounded caches grow per-tool-call; they grow per **distinct query** / **distinct cwd** / **distinct skill name** / **distinct gap signal** / **distinct promotion**, which is sub-linear in session length but monotone forever.
+- A long-running daemon-style process (KAIROS sessions, multi-day worktrees) would observe the growth.
+
+## 2. Module-level state audit
+
+| File:Line | Symbol | Pre-fix bound | Pre-fix evict |
+|---|---|---|---|
+| `intentNormalize.ts:52` | `cache: Map<query, keywords>` | none | only `clearIntentNormalizeCache()` for tests |
+| `prefetch.ts:17` | `discoveredThisSession: Set<skillName>` | none | none |
+| `prefetch.ts:18` | `recordedGapSignals: Set<gapKey>` | none | none |
+| `projectContext.ts:48` | `contextCache: Map<cwd, ProjectContext>` | none | only `resetProjectContextCacheForTest()` |
+| `promotion.ts:26` | `sessionPromotedIds: Set<instinctId>` | none | only `resetPromotionBookkeeping()` for tests |
+| `runtimeObserver.ts:61` | `lastProcessedMessageIds: Set<msgKey>` | **MAX 1000** | FIFO trim ✓ already bounded |
+| `toolEventObserver.ts:50` | `emittedTurns: Map<sid, Set<turn>>` | **MAP_MAX 50, SET_MAX 100** | LRU prune via `pruneEmittedTurns()` called inside `markTurn` ✓ already bounded |
+| `observerBackend.ts:21` | `registry: Map<name, Backend>` | fixed N | n/a — registry pattern, finite ✓ |
+
+**5 unbounded out of 8 module-level mutables.** All 5 are addressed in this PR.
+
+## 3. Severity rationale
+
+Per-entry cost is small (key strings + small objects), so OOM in days is unlikely on a normal workstation. But the canary scenarios:
+
+- **`intentNormalize.cache`**: every distinct Chinese query → Haiku call → cached. A session that browses a large Chinese codebase or replays many transcripts can hit thousands of distinct queries; ~600 bytes per entry × 10k = ~6 MB. Plus, **every cache miss is a Haiku API call**, so default-enabled means every fresh session pays a request on first non-ASCII query — unintended cost.
+- **`projectContext.contextCache`**: each `SkillLearningProjectContext` carries instinct + skill lists. Multi-worktree orchestrators (this very repo!) blow past the typical "1 cwd per session" assumption.
+- **`prefetch` Sets**: in chatty sessions thousands of skill discovery names accumulate.
+- **`sessionPromotedIds`**: smallest practical risk (single-digit promotions per session normally), but a long-lived sandbox could push it; a defensive cap is cheap.
+
+The fix bounds all 5 with FIFO/LRU eviction at sensible sizes (200–1000 entries). No data-corruption risk: degraded behaviour on cap-overflow is benign (re-emit a duplicate signal, re-Haiku a query, re-resolve a cwd context). Same risk profile as the autonomy stale-recovery design.
+
+## 4. Fix surface
+
+| File | Change |
+|---|---|
+| `src/services/skillSearch/intentNormalize.ts` | `setCachedQueryIntent()` helper, `CACHE_MAX_ENTRIES=200` / `CACHE_TRIM_TO=150`, LRU touch on hit |
+| `src/services/skillSearch/prefetch.ts` | `addBoundedSessionEntry()` helper, `SESSION_TRACKING_MAX=1000` / `TRIM_TO=750`; `discoveredThisSession` and `recordedGapSignals` route through it |
+| `src/services/skillLearning/projectContext.ts` | `setProjectContextCache()` helper, `PROJECT_CONTEXT_CACHE_MAX=32` / `TRIM_TO=24`, LRU touch on hit |
+| `src/services/skillLearning/promotion.ts` | `recordSessionPromoted()` helper, `SESSION_PROMOTED_IDS_MAX=256` / `TRIM_TO=192` |
+| `src/services/skillSearch/featureCheck.ts` | Two-layer gate: build flag must be on AND `SKILL_SEARCH_ENABLED=1` env must be set. Defaults to OFF when env is unset, so the slash command remains visible but the runtime hot paths stay dormant until the operator explicitly enables. |
+| `src/services/skillLearning/featureCheck.ts` | Same two-layer pattern (build flag + `SKILL_LEARNING_ENABLED=1` or legacy `FEATURE_SKILL_LEARNING=1`). |
+| `scripts/defines.ts` | Comment annotated to clarify that the build flags now serve only to compile commands in; runtime activation is operator-driven. |
+
+## 5. Why default-off (without removing from build)?
+
+Three reasons aside from the unbounded-cache concern:
+
+1. **Implicit cost**: `intentNormalize` calls Haiku on cache miss. Default-on means every session that types Chinese pays an API call, even when the operator never asked for skill search.
+2. **Disk side effects**: `SKILL_LEARNING` attaches observers that persist observations to `~/.claude` storage. Storage volume should be opt-in, not background.
+3. **Experimental status**: the flag is literally named `EXPERIMENTAL_*`. Default-enabling an experimental subsystem contradicts the naming contract.
+
+**The fix is NOT to remove the flags from `DEFAULT_BUILD_FEATURES`** — doing so would also strip the `/skill-search` and `/skill-learning` slash commands from the build, leaving operators with no UI to opt in. Instead the activation logic in `featureCheck.ts` was changed to a two-layer gate:
+
+- **Layer 1 (compile-time)**: `feature('EXPERIMENTAL_SKILL_SEARCH')` / `feature('SKILL_LEARNING')` must be on. These remain in `DEFAULT_BUILD_FEATURES` so the slash commands and observers are compiled in.
+- **Layer 2 (runtime)**: `SKILL_SEARCH_ENABLED=1` / `SKILL_LEARNING_ENABLED=1` (or `FEATURE_SKILL_LEARNING=1`) env var must be set. Without this, the subsystems are present but dormant — the slash command exists and toggling it via `/skill-search` or `/skill-learning` flips the env var and activates the hot paths.
+
+Net result: operators see the toggle in the UI but the subsystem is **off until they flip it**.
+
+## 6. Out of scope (filed for follow-up)
+
+- **Test failures on CI** (`prefetch.test.ts > auto-loads high-confidence project skill content`, `skillLearningSmoke.test.ts > ingests corrections, evolves a learned skill, and skill search finds it`) appear in this branch's CI run. Both tests **explicitly enable** the features via env vars, so default-disabling does not cause them. They are pre-existing functional issues in the experimental code paths and warrant their own flow once the bug-classification step is run. Default-disable in this PR avoids exposing operators to unknown failure modes while triage proceeds.
+- **Persistence-layer bounds** (observation files, instinct registry): `observationStore.ts` already has 30-day purge and 1MB archive thresholds; `skillGapStore.ts` uses a finite-state lifecycle. Disk-side state is appropriately bounded; the OOM-class issue was strictly in-process state.
+
+## 7. Verification
+
+Local checks (full suite covers cap behaviour via existing tests; the caps degrade gracefully so no test should break):
+
+```bash
+bun run typecheck   # 0 errors
+bun test src/services/skillSearch/__tests__/intentNormalize.test.ts
+bun test src/services/skillSearch/__tests__/prefetch.extractQuery.test.ts
+bun test src/services/skillLearning/__tests__/projectContext.test.ts
+bun test src/services/skillLearning/__tests__/promotion.test.ts
+bun run lint
+bun run build
+```
+
+The new caps are observable behaviour: under sustained load the Map/Set sizes plateau at the configured maxima rather than monotone-growing.

-# Feature Flags 审查报告 — Codex 复核
-
-> 审查日期: 2026-04-05
-> 审查工具: Codex CLI v0.118.0 (本地, full-auto mode)
-> 消耗 tokens: 240,306
-> 审查范围: docs/feature-flags-audit-complete.md 中标记为 COMPLETE 的 22 个编译时 feature flag
-
----
-
-## 审查背景
-
-原始审计报告 (`docs/feature-flags-audit-complete.md`) 声称 22 个 feature flag 被标记为 "COMPLETE"，只需在 `build.ts` / `scripts/dev.ts` 中启用即可工作。
-
-Claude Code 团队通过 6 个并行子代理实际读取源码后初步发现大量误判，随后将分析结果传递给 Codex CLI 进行独立二次验证。

-## Codex 发现摘要
-
-### High 级发现
-
-1. **`CONTEXT_COLLAPSE` 不是 COMPLETE**
-   - `src/services/contextCollapse/index.ts:43` — `isContextCollapseEnabled()` 硬编码为 `false`
-   - `src/services/contextCollapse/index.ts:47` — `applyCollapsesIfNeeded()` 只是原样返回消息
-   - `src/services/contextCollapse/index.ts:59` — `recoverFromOverflow()` 也是 no-op
-   - `src/services/contextCollapse/operations.ts:3` 和 `persist.ts:3` 同样是 stub
-   - 审计报告把 UI/命令文件算进去了，但真正被查询循环消费的是 stub 后端
-
-2. **原分类"真正只需编译开关"的 7 个 flag，只有 3 个准确**
-   - ✅ `SHOT_STATS` — 零额外门控，compile-only
-   - ✅ `PROMPT_CACHE_BREAK_DETECTION` — 有 try-catch 兜底，compile-only
-   - ✅ `TOKEN_BUDGET` — 纯本地计算，compile-only
-   - ❌ `TEAMMEM` — 还要求 AutoMem + GrowthBook `tengu_herring_clock` + GitHub repo (`teamMemPaths.ts:73`, `watcher.ts:256`, `watcher.ts:259`)
-   - ❌ `AGENT_TRIGGERS` — 受 `isKairosCronEnabled()` GrowthBook 控制 (`useScheduledTasks.ts:61`, `useScheduledTasks.ts:119`)
-   - ❌ `EXTRACT_MEMORIES` — 受 `tengu_passport_quail` + AutoMem + 非 remote 限制 (`extractMemories.ts:536`, `:545`, `:550`)
-   - ❌ `KAIROS_BRIEF` — 受 `tengu_kairos_brief` + opt-in/kairosActive 限制 (`BriefTool.ts:95`, `:126`, `:132`)
-
-### Medium 级发现
-
-3. **`BG_SESSIONS` 和 `BASH_CLASSIFIER` 不适合简单归为"全 stub"**
-   - `BG_SESSIONS` — 会话注册/清理是真实现 (`concurrentSessions.ts:44`, `:55`)，但任务摘要核心是 stub (`taskSummary.ts:2`)
-   - `BASH_CLASSIFIER` — 权限编排很大一块是真实现 (`bashPermissions.ts` 2621行)，但分类后端 `bashClassifier.ts:24` 永远返回 disabled
-
-4. **审计口径问题**
-   - 把"代码量/周边 UI 很多"误当成"可独立启用"
-   - `PROACTIVE` — `index.ts:3` 只有 state stub，`commands.ts:64` 和 `REPL.tsx:415` 引用缺失文件
-   - `REACTIVE_COMPACT` — `reactiveCompact.ts:13` 整块是 stub
-   - `CACHED_MICROCOMPACT` — `cachedMicrocompact.ts:22` 全部 stub

-## Codex 修正后的分类
-
-### 第一类：真正 compile-only（3 个）
-
-| Flag | 说明 | Crash 风险 |
-|------|------|-----------|
-| **SHOT_STATS** | 纯本地 shot 分布统计，ant-only 数据路径 | 低 |
-| **PROMPT_CACHE_BREAK_DETECTION** | 本地 cache key 变化检测，写 diff 有兜底 | 低 |
-| **TOKEN_BUDGET** | 本地 token 预算追踪，纯计算逻辑 | 低 |
-
-### 第二类：compile + 运行时条件（7 个）
-
-| Flag | 条件 | Crash 风险 |
-|------|------|-----------|
-| **TEAMMEM** | AutoMem + GrowthBook `tengu_herring_clock` + GitHub repo | 低 (clean no-op) |
-| **AGENT_TRIGGERS** | GrowthBook `isKairosCronEnabled()` | 低 (clean no-op) |
-| **EXTRACT_MEMORIES** | `tengu_passport_quail` + AutoMem + 非 remote | 低 (clean no-op) |
-| **KAIROS_BRIEF** | `tengu_kairos_brief` + opt-in/kairosActive，可用 `CLAUDE_CODE_BRIEF=1` 绕过 | 低 |
-| **COORDINATOR_MODE** | 需 `CLAUDE_CODE_COORDINATOR_MODE=1`，`workerAgent.ts` 是 stub 但不阻塞 | 低 |
-| **COMMIT_ATTRIBUTION** | 仅对 `isInternal=true` 的 repo 生效 | 低 |
-| **VERIFICATION_AGENT** | 受 GrowthBook `tengu_hive_evidence` 双重门控 | 低 |
-
-### 第三类：混合型 — 部分实现 + stub 核心（5 个）
-
-| Flag | 真实现部分 | Stub 核心 |
-|------|-----------|----------|
-| **BG_SESSIONS** | 会话注册/清理 (`concurrentSessions.ts`) | `bg.ts`/`taskSummary.ts`/`udsClient.ts` 全 stub + 依赖 tmux |
-| **BASH_CLASSIFIER** | 权限编排 (`bashPermissions.ts` 2621行) | `bashClassifier.ts` 分类后端 stub + 需 API beta |
-| **PROACTIVE** | REPL/命令注册框架 | `index.ts` stub + 3 文件缺失 |
-| **REACTIVE_COMPACT** | 调用点已在主查询环路 | `reactiveCompact.ts` 22行全 no-op |
-| **CACHED_MICROCOMPACT** | 调用点已布线 | `cachedMicrocompact.ts` 全 stub + 需未公开 API |
-
-### 第四类：纯 stub（1 个）
-
-| Flag | 问题 |
-|------|------|
-| **CONTEXT_COLLAPSE** | 3 核心文件全 stub + CtxInspectTool 目录不存在 |
-
-### 第五类：依赖远程服务（3 个）
-
-| Flag | 依赖 |
-|------|------|
-| **ULTRAPLAN** | CCR 远程 agent 基础设施 + OAuth |
-| **CCR_REMOTE_SETUP** | claude.ai OAuth + GitHub CLI + CCR 后端 |
-| **BRIDGE_MODE** (build端) | claude.ai 订阅 + GrowthBook + WebSocket 后端 |
-
----
-
-## 第三类恢复优先级建议
-
-Codex 推荐的恢复顺序：
-
-1. **REACTIVE_COMPACT** — 收益最直接，调用点在主查询环路，改完最容易立刻见效
-2. **BG_SESSIONS** — 已有会话注册基础，补齐摘要和后台运行链路的 ROI 高
-3. **PROACTIVE** — 产品面大，但缺文件比 stub 更严重，范围比前两项大
-4. **CONTEXT_COLLAPSE** — collapse engine 全 stub，恢复成本和设计不确定性都高
-5. **BASH_CLASSIFIER** — 若无 API beta 能力不值得优先；若有则升到第 2
-6. **CACHED_MICROCOMPACT** — 受未公开 API 约束，最后做
-
----
-
-## 审计报告分类标准修正建议
-
-Codex 建议将原来的单轴分类（COMPLETE/PARTIAL/STUB）改为**三轴**：
-
-| 轴 | 取值 | 说明 |
-|----|------|------|
-| **实现完整度** | `full` / `mixed` / `stub` | 活跃调用链上的核心模块是否有真实现 |
-| **激活条件** | `compile-only` / `compile+env` / `compile+GrowthBook` / `compile+remote` / `compile+private API` | 启用需要什么 |
-| **运行风险** | `safe no-op` / `background IO` / `startup critical` | 启用后条件不满足时的行为 |
-
-**COMPLETE 的最低标准应满足：**
-1. 活跃调用链上的核心模块不能是 stub
-2. "可启用"不能只看编译 flag，还要单列运行时 gate
-
-按此标准，`CONTEXT_COLLAPSE`、`BG_SESSIONS`、`BASH_CLASSIFIER`、`PROACTIVE`、`REACTIVE_COMPACT`、`CACHED_MICROCOMPACT` 都应从 COMPLETE 降级。

+1. **SSH Remote 模块**（`ccb ssh <host>`）— 本地 REPL + 远程工具执行，自动部署二进制 + 认证隧道
+2. **直接 SSH 运行**（`ssh <host> -t ccb`）— 远程已安装 ccb，直接启动交互式会话

+
+## 前置准备：SSH 密钥配置
+
+两种方式都依赖 SSH 免密连接。以下是完整的密钥配置步骤。
+
+### 1. 生成 SSH 密钥对（本地）
+
+```bash
+# 生成 Ed25519 密钥（推荐）
+ssh-keygen -t ed25519 -C "your-email@example.com" -f ~/.ssh/id_remote
+
+# 或 RSA 4096 位
+ssh-keygen -t rsa -b 4096 -C "your-email@example.com" -f ~/.ssh/id_remote
+```
+
+生成两个文件：
+- `~/.ssh/id_remote` — 私钥（不可泄露）
+- `~/.ssh/id_remote.pub` — 公钥（部署到远端）
+
+### 2. 将公钥部署到远端
+
+```bash
+# 方式 A：ssh-copy-id（推荐）
+ssh-copy-id -i ~/.ssh/id_remote.pub user@remote-host
+
+# 方式 B：手动复制
+cat ~/.ssh/id_remote.pub | ssh user@remote-host "mkdir -p ~/.ssh && chmod 700 ~/.ssh && cat >> ~/.ssh/authorized_keys && chmod 600 ~/.ssh/authorized_keys"
+```
+
+### 3. 配置 SSH Config（本地）
+
+编辑 `~/.ssh/config`（不存在则创建）：
+
+```
+Host my-server
+    HostName 192.168.1.100       # 远端 IP 或域名
+    User root                     # 远端用户名
+    IdentityFile ~/.ssh/id_remote # 私钥路径
+    ServerAliveInterval 60        # 防止连接超时断开
+    ServerAliveCountMax 3
+```
+
+配置后可直接用别名连接：
+
+```bash
+ssh my-server          # 等同于 ssh -i ~/.ssh/id_remote root@192.168.1.100
+```
+
+### 4. 文件权限设置
+
+#### Linux / macOS
+
+```bash
+chmod 700 ~/.ssh
+chmod 600 ~/.ssh/config
+chmod 600 ~/.ssh/id_remote
+chmod 644 ~/.ssh/id_remote.pub
+```
+
+#### Windows（OpenSSH 强制 ACL 检查）
+
+```powershell
+# 重置 .ssh 目录权限：仅允许当前用户 + SYSTEM
+icacls "$env:USERPROFILE\.ssh" /inheritance:r /grant:r "$($env:USERNAME):(OI)(CI)F" /grant "SYSTEM:(OI)(CI)F"
+
+# 修复 config 文件权限
+icacls "$env:USERPROFILE\.ssh\config" /inheritance:r /grant:r "$($env:USERNAME):F" /grant "SYSTEM:F"
+
+# 修复私钥权限
+icacls "$env:USERPROFILE\.ssh\id_remote" /inheritance:r /grant:r "$($env:USERNAME):F" /grant "SYSTEM:F"
+```
+
+> **Windows 常见错误**：如果 `icacls` 显示 `UNKNOWN\UNKNOWN` ACL 条目，需要先移除再重新授权。权限错误会导致 SSH 拒绝使用密钥。
+
+### 5. 验证免密连接
+
+```bash
+ssh my-server "echo 'SSH connection OK'"
+# 应直接输出 "SSH connection OK"，不要求输入密码
+```
+
+---
+
+## 使用方式
+
+### 方式一：SSH Remote 模块
+
+```bash
+# 基本用法 — 自动探测、部署、启动
+ccb ssh user@remote-host
+
+# 使用 SSH Config 别名
+ccb ssh my-server
+
+# 指定远端工作目录
+ccb ssh my-server /home/user/project
+
+# 使用自定义远端二进制（跳过探测/部署）
+ccb ssh my-server --remote-bin "bun /opt/ccb/dist/cli.js"
+
+# 权限控制
+ccb ssh my-server --permission-mode auto
+ccb ssh my-server --dangerously-skip-permissions
+
+# 恢复远端会话
+ccb ssh my-server --continue
+ccb ssh my-server --resume <session-uuid>
+
+# 选择模型
+ccb ssh my-server --model claude-sonnet-4-6-20250514
+
+# 本地测试模式（不连接远端，测试 auth proxy 管道）
+ccb ssh localhost --local
+```
+
+### 方式二：直接 SSH 运行
+
+```bash
+# 启动交互式会话
+ssh my-server -t ccb
+
+# 指定工作目录
+ssh my-server -t "ccb --cwd /home/user/project"
+
+# 使用特定模型
+ssh my-server -t "ccb --model claude-sonnet-4-6-20250514"
+```
+
+---
+
+## 构建与部署
+
+### 构建产物
+
+```bash
+# 安装依赖
+bun install
+
+# 构建（输出到 dist/）
+bun run build
+```
+
+产物说明：
+
+| 文件 | 说明 |
+|------|------|
+| `dist/cli.js` | Bun 入口（`#!/usr/bin/env bun`） |
+| `dist/cli-node.js` | Node.js 入口（`#!/usr/bin/env node` → `import ./cli.js`） |
+| `dist/cli-bun.js` | Bun 专用入口 |
+| `dist/chunk-*.js` | 代码分割 chunk 文件（约 668 个） |
+
+### 运行方式
+
+```bash
+# 方式 A：通过 bun 直接运行（开发/调试）
+bun run dev
+
+# 方式 B：运行构建产物（bun 运行时）
+bun dist/cli.js
+
+# 方式 C：运行构建产物（node 运行时）
+node dist/cli-node.js
+
+# 方式 D：全局安装后使用命令名
+ccb
+```
+
+### 全局安装
+
+在项目根目录执行：
+
+```bash
+# bun 全局安装（推荐）
+bun install -g .
+
+# 创建的命令：
+#   ccb            → dist/cli-node.js
+#   ccb-bun        → dist/cli-bun.js
+#   claude-code-best → dist/cli-node.js
+
+# 安装位置：~/.bun/bin/ccb
+```
+
+或使用 npm：
+
+```bash
+npm install -g .
+```
+
+验证：
+
+```bash
+ccb --version
+# → x.x.x (Claude Code)
+```
+
+### 远端部署（全流程）
+
+```bash
+# 1. 登录远端
+ssh my-server
+
+# 2. 克隆或同步项目代码
+git clone <repo-url> ~/ccb-project
+cd ~/ccb-project
+
+# 3. 安装运行时（如果没有 bun）
+curl -fsSL https://bun.sh/install | bash
+source ~/.bashrc
+
+# 4. 安装依赖 + 构建
+bun install
+bun run build
+
+# 5. 全局安装
+bun install -g .
+
+# 6. 确保非交互式 SSH 可访问 ccb 命令
+#    bun install -g 安装到 ~/.bun/bin/，但非交互式 SSH 不加载 .bashrc，
+#    所以 PATH 中不包含 ~/.bun/bin/
+#    解决方式（任选其一）：
+
+# 方式 A：符号链接到系统 PATH（推荐）
+ln -sf ~/.bun/bin/ccb /usr/local/bin/ccb
+
+# 方式 B：添加到 /etc/profile.d/（所有用户生效）
+echo 'export PATH="$HOME/.bun/bin:$PATH"' > /etc/profile.d/bun-path.sh
+
+# 方式 C：添加到 ~/.bash_profile（当前用户，ssh -t 时生效）
+echo 'export PATH="$HOME/.bun/bin:$PATH"' >> ~/.bash_profile
+
+# 7. 验证
+ccb --version
+
+# 8. 从本地测试
+# （在本地终端）
+ssh my-server -t ccb
+```
+
+### SSH Remote 自动部署
+
+使用 `ccb ssh <host>` 时，模块自动处理：
+
+1. **SSHProbe** 探测远端 `~/.local/bin/claude` 或 `command -v claude`
+2. 若二进制不存在或版本不匹配，**SSHDeploy** 通过 `scp` 传输 `dist/` 目录
+3. 在远端创建 wrapper 脚本（`~/.local/bin/claude`）
+4. 无需手动安装
+

+
+## 模块结构
+
+```
+src/ssh/
+├── createSSHSession.ts     — 会话工厂：编排 probe → deploy → proxy → spawn
+├── SSHSessionManager.ts    — 双向 NDJSON 通信管理 + 权限转发 + 重连

+└── __tests__/
+    └── SSHSessionManager.test.ts  — 17 个单元测试
+```
+
+## 关键技术细节
+
+### 认证隧道
+
+- **AuthProxy** 在本地监听（Unix socket 或 TCP），接收远端 CLI 的 API 请求
+- 通过 SSH `-R` 反向端口转发隧道到远端
+- AuthProxy 注入本地真实凭据（API key 或 OAuth token），转发到 `api.anthropic.com`
+- `ANTHROPIC_AUTH_NONCE` header 防止未授权访问（nonce 通过环境变量传递给远端 CLI，远端 CLI 在每个 API 请求中携带此 header）
+
+### waitForInit vs 存活检查
+
+- **标准模式**：`waitForInit` 等待远端 CLI 发送 `{type:'system', subtype:'init'}` JSON 消息
+- **`--remote-bin` 模式**：跳过 `waitForInit`（print+stream-json 模式下 init 只在首次查询后发送），改用 3 秒进程存活检查
+
+### 重连机制
+
+- `SSHSessionManager` 检测 SSH 连接断开后自动重连
+- 重连时在远端 CLI 命令中追加 `--continue` 恢复会话
+- 指数退避重试（最多 5 次，间隔 1s → 2s → 4s → 8s → 16s）
+
+## Feature Flag
+
+SSH Remote 功能受 `SSH_REMOTE` feature flag 控制：
+
+- **Dev 模式**：默认启用
+- **Build 模式**：需在 `build.ts` 的 `DEFAULT_BUILD_FEATURES` 中添加 `'SSH_REMOTE'`
+- **运行时**：`FEATURE_SSH_REMOTE=1` 环境变量
+
+---
+
+## 常见问题
+
+### `ccb: command not found`（SSH 远程执行时）
+
+非交互式 SSH 不加载 `.bashrc`，`~/.bun/bin` 不在 PATH 中。
+
+```bash
+# 解决：创建符号链接
+ln -sf ~/.bun/bin/ccb /usr/local/bin/ccb
+```
+
+### SSH 密钥被拒绝
+
+```
+Permission denied (publickey)
+```
+
+1. 确认公钥已添加到远端 `~/.ssh/authorized_keys`
+2. 确认本地私钥文件权限正确（`chmod 600`）
+3. 确认 `~/.ssh/config` 中 `IdentityFile` 路径正确
+4. Windows 用户检查 ACL 权限（见上方 Windows 权限设置）
+
+### SSH 连接超时
+
+```
+ssh: connect to host x.x.x.x port 22: Connection timed out
+```
+
+1. 确认远端 SSH 服务正在运行：`systemctl status sshd`
+2. 确认防火墙允许 22 端口
+3. 确认 IP 地址/域名正确
+4. 在 `~/.ssh/config` 中添加 `ConnectTimeout 10`
+
+### 403 Forbidden（SSH Remote 模块）
+
+AuthProxy 的 nonce 验证失败。确认：
+1. 远端 CLI 版本包含 nonce header 注入修复
+2. `ANTHROPIC_AUTH_NONCE` 环境变量正确传递到远端
+3. `src/services/api/client.ts` 中 `x-auth-nonce` header 已启用
+
+### 远端 CLI 启动后立即退出
+
+```
+Remote process exited immediately (code 1)
+```
+
+1. 确认远端 `bun` / `node` 运行时可用
+2. 手动在远端执行 `ccb --version` 验证安装
+3. 检查 `--remote-bin` 路径是否正确
+4. 查看 stderr 输出获取详细错误信息

 # VOICE_MODE — 语音输入
 
 > Feature Flag: `FEATURE_VOICE_MODE=1`
-> 实现状态：完整可用（需要 Anthropic OAuth）

 > 引用数：46
 
 ## 一、功能概述
 
-VOICE_MODE 实现"按键说话"（Push-to-Talk）语音输入。用户按住空格键录音，音频通过 WebSocket 流式传输到 Anthropic STT 端点（Nova 3），实时转录显示在终端中。
+VOICE_MODE 实现"按键说话"（Push-to-Talk）语音输入。用户按住空格键录音，音频流式传输到 STT 后端，实时转录显示在终端中。支持两个后端：
+
+- **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
+- **双后端切换**：通过 `/voice` 命令参数选择 STT 后端，持久化到 settings.json
 
 ## 二、用户交互
 
 | 操作 | 行为 |
 |------|------|
 | 长按空格 | 开始录音，显示录音状态 |
-| 释放空格 | 停止录音，等待最终转录 |
-| 转录完成 | 自动插入到输入框并提交 |
-| `/voice` 命令 | 切换语音模式开关 |
+| 释放空格 | 停止录音，转录结果自动提交 |
+| `/voice` | 切换语音模式开关（默认使用 Anthropic 后端） |

+### 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。

+
+#### 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。

+- 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

+
+- 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

+
+- 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

+- `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

+- `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

+- 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
+

+# Autonomy Reliability Jira Drafts
+
+These tickets are based on the call-chain audit of `/autonomy`, proactive
+ticks, HEARTBEAT managed flows, cron scheduling, command queue consumption,
+and daemon process supervision.
+
+## AUT-001: Preserve autonomy lifecycle when queued commands are consumed mid-turn
+
+Type: Bug
+Priority: P0
+Status: Draft
+Patch status: Implemented in `fix/autonomy-lifecycle`.
+
+Problem:
+`query.ts` can drain queued prompt/task-notification commands as attachments
+during an active turn. Autonomy prompts consumed this way were removed from the
+in-memory queue without marking the persisted run as running/completed/failed,
+so managed flows could stay stuck in `queued` and never advance.
+
+Evidence:
+- `src/query.ts` drains queued commands via `getCommandsByMaxPriority()`.
+- `src/query.ts` removes consumed commands from the queue.
+- Lifecycle updates existed only in the normal queued-submit path
+  `src/utils/handlePromptSubmit.ts` and headless `src/cli/print.ts`.
+
+Acceptance criteria:
+- Mid-turn consumed autonomy commands mark runs `running`.
+- Normal query completion finalizes consumed runs and queues next managed-flow
+  steps.
+- Query errors or abort terminal reasons mark consumed runs failed.
+- Stale/cancelled autonomy commands are removed from the in-memory queue
+  without being sent to the model.
+- Regression tests cover stale command filtering and managed-flow advancement.
+
+## AUT-002: Make autonomy run lifecycle transitions terminal-safe
+
+Type: Bug
+Priority: P0
+Status: Draft
+Patch status: Implemented in `fix/autonomy-lifecycle`.
+
+Problem:
+Run lifecycle helpers rewrote status unconditionally. A stale in-memory command
+could mark a cancelled/completed/failed run back to `running`, causing a
+cancelled flow to execute or a terminal flow to be rewritten.
+
+Evidence:
+- `markAutonomyRunRunning`, `markAutonomyRunCompleted`,
+  `markAutonomyRunFailed`, and `markAutonomyRunCancelled` updated records
+  without checking current status.
+- External CLI cancel cannot remove queued commands living inside another
+  process, so stale commands are a realistic input.
+
+Acceptance criteria:
+- `queued -> running/completed/failed/cancelled` remains allowed.
+- `running -> completed/failed/cancelled` remains allowed.
+- Any terminal status rejects later lifecycle updates.
+- Rejected transitions do not update managed-flow step state.
+- Regression tests cover stale lifecycle calls after cancellation.
+
+## AUT-003: Prevent proactive and scheduled-task async fire failures from becoming invisible
+
+Type: Bug
+Priority: P1
+Status: Draft
+Patch status: Implemented in `fix/autonomy-lifecycle`.
+
+Problem:
+Proactive tick and cron fire callbacks launch detached async work. Failures in
+prompt preparation or queue insertion could surface as unhandled rejections or
+be lost from diagnostics. In one-shot cron paths, the scheduler has already
+decided the task fired.
+
+Evidence:
+- `src/proactive/useProactive.ts` used a detached async IIFE without catch.
+- `src/cli/print.ts` proactive and cron paths also detached async work.
+- `src/hooks/useScheduledTasks.ts` cron callbacks detached async work.
+
+Acceptance criteria:
+- Detached proactive/cron fire work has explicit error logging.
+- REPL proactive tick generation is non-reentrant.
+- Tick generation stops queueing after hook unmount.
+
+## AUT-004: Bound long-running daemon restart timers during shutdown
+
+Type: Bug
+Priority: P1
+Status: Draft
+Patch status: Implemented in `fix/autonomy-lifecycle`.
+
+Problem:
+The daemon supervisor scheduled worker restarts with `setTimeout()` but did
+not store, clear, or `unref()` the timer. Shutdown during backoff could keep
+the supervisor alive until the timer fired, forcing the stop path toward
+SIGKILL.
+
+Evidence:
+- `src/daemon/main.ts` scheduled restart timers directly in the worker exit
+  handler.
+- Shutdown only signaled child processes and did not clear restart timers.
+
+Acceptance criteria:
+- Worker restart timers are tracked per worker.
+- Shutdown clears any pending restart timers.
+- Restart and force-kill grace timers do not keep the supervisor alive alone.
+
+## AUT-005: Release autonomy persistence lock bookkeeping after each chain
+
+Type: Bug
+Priority: P1
+Status: Draft
+Patch status: Implemented in `fix/autonomy-lifecycle`.
+
+Problem:
+`withAutonomyPersistenceLock` stored a chained promise in its map but compared
+the map value against the raw current promise during cleanup. That condition
+never matched, so root-level lock bookkeeping could accumulate in long-lived
+processes that touch many workspaces.
+
+Evidence:
+- `src/utils/autonomyPersistence.ts` stored `previous.then(() => current)`.
+- Cleanup compared `persistenceLocks.get(key) === current`.
+
+Acceptance criteria:
+- The stored chained promise is the value used for cleanup comparison.
+- Existing serialization behavior for same-root calls remains unchanged.
+- Tests directly assert same-root lock bookkeeping returns to zero after both
+  success and failure.
+
+## AUT-006: Add active-record protection before persistence truncation
+
+Type: Reliability
+Priority: P2
+Status: Draft
+Patch status: Implemented in `fix/autonomy-lifecycle`.
+
+Problem:
+Autonomy runs and flows are capped by latest-created/updated order only.
+Under high churn, active `queued` or `running` records can be truncated before
+completion, which removes recovery evidence and can break managed-flow
+advancement.
+
+Evidence:
+- `src/utils/autonomyRuns.ts` keeps the latest 200 runs by `createdAt`.
+- `src/utils/autonomyFlows.ts` keeps the latest 100 flows by `updatedAt`.
+
+Acceptance criteria:
+- Active records are retained before completed historical records are trimmed.
+- Tests cover trimming with more than the configured cap and active records
+  near the tail.
+
+## AUT-007: Treat provider API-error responses as failed autonomy turns
+
+Type: Bug
+Priority: P0
+Status: Draft
+Patch status: Implemented in `fix/autonomy-lifecycle`.
+
+Problem:
+Third-party provider adapters can convert provider failures into synthetic
+assistant API-error messages instead of throwing. `query.ts` treated
+`isApiErrorMessage` terminal responses as `completed`, so an autonomy command
+that had already been consumed as a queued attachment could be marked
+completed and advance its managed flow even though the provider call failed.
+
+Evidence:
+- `src/services/api/openai/index.ts`, `src/services/api/gemini/index.ts`, and
+  `src/services/api/grok/index.ts` yield `createAssistantAPIErrorMessage()` on
+  adapter errors.
+- `src/query.ts` skipped stop hooks for API-error assistant messages but
+  returned `reason: 'completed'`.
+- Top-level autonomy finalization used terminal completion to decide whether
+  to mark consumed runs completed or failed.
+
+Acceptance criteria:
+- Provider API-error assistant messages terminate the query with
+  `reason: 'model_error'`.
+- Any consumed autonomy run is marked failed rather than completed.
+- Managed flows do not advance to the next step after provider API errors.
+- A regression test simulates provider error after a queued autonomy attachment
+  has been consumed.
+
+## AUT-008: Finalize consumed autonomy runs on async-generator close
+
+Type: Bug
+Priority: P0
+Status: Draft
+Patch status: Implemented in `fix/autonomy-lifecycle`.
+
+Problem:
+`query()` is an async generator. When its consumer calls `.return()` or breaks
+out of iteration, JavaScript executes `finally` blocks and skips code after the
+`try/finally`. The previous autonomy finalization ran after the `finally`, so
+queued autonomy commands that had already been claimed as `running` could stay
+persisted as `running` forever if the REPL/SDK consumer closed the generator.
+
+Evidence:
+- Claimed run IDs were collected during queued attachment injection.
+- Completion/failure finalization happened only after `yield* queryLoop(...)`
+  returned normally or threw.
+- Claude cross-validation flagged this as a durable run/flow leak.
+
+Acceptance criteria:
+- Consumed autonomy runs are finalized from a `finally` path.
+- Normal completion marks consumed runs completed and enqueues next managed
+  flow steps.
+- Provider/model errors mark consumed runs failed.
+- Generator close and user abort terminals mark consumed runs cancelled.
+- A regression test closes the generator after a queued autonomy attachment and
+  verifies the run/flow are cancelled, not left running.
+
+## AUT-009: Claim queued autonomy runs before attachment injection
+
+Type: Bug
+Priority: P0
+Status: Draft
+Patch status: Implemented in `fix/autonomy-lifecycle`.
+
+Problem:
+The query loop filtered stale queued autonomy commands before attachment
+generation, but it did not claim runs as `running` until after attachments were
+already yielded. A concurrent cancellation between those steps could still send
+a cancelled prompt into the model context.
+
+Evidence:
+- `partitionConsumableQueuedAutonomyCommands()` only checked persisted status.
+- `markAutonomyRunRunning()` previously ran after `getAttachmentMessages()`.
+- Reviewer cross-validation identified the check-then-act race.
+
+Acceptance criteria:
+- Query claims queued autonomy runs before passing commands to attachment
+  generation.
+- Only successfully claimed commands are injected as queued-command
+  attachments.
+- Failed claims are treated as stale and removed from the in-memory queue.
+- Claiming reads persisted run state once per turn rather than once per
+  command.
+
+## AUT-010: Cancel proactive and cron runs dropped before enqueue
+
+Type: Bug
+Priority: P1
+Status: Draft
+Patch status: Implemented in `fix/autonomy-lifecycle`.
+
+Problem:
+`/proactive` and scheduled-task producers persist autonomy runs before
+returning queue commands. If the component is disposed or headless input closes
+after persistence but before enqueue, the queued run is left on disk with no
+in-memory command to consume it.
+
+Evidence:
+- `createProactiveAutonomyCommands()` commits runs before returning commands.
+- `commitAutonomyQueuedPrompt()` persists scheduled-task runs before callers
+  enqueue them.
+- Callers checked `disposed` / `inputClosed` after command creation and could
+  return without terminalizing the run.
+
+Acceptance criteria:
+- Proactive hook cancellation checks run both before commit and after command
+  creation.
+- Headless proactive and cron paths cancel any already-created command that is
+  dropped due to input close.
+- REPL scheduled-task cleanup cancels already-created commands when unmounted.
+- A regression test verifies a proactive command created but dropped before
+  enqueue is marked cancelled.
+
+## AUT-011: Replace query transition `any` stubs with typed contracts
+
+Type: Test/Type Safety
+Priority: P2
+Status: Draft
+Patch status: Implemented in `fix/autonomy-lifecycle`.
+
+Problem:
+`src/query/transitions.ts` defined both `Terminal` and `Continue` as `any`.
+That allowed new terminal reasons such as `model_error` and continuation
+reasons such as `collapse_drain_retry` to drift without compiler checks.
+
+Evidence:
+- Claude cross-validation flagged the `Terminal = any` contract as a remaining
+  issue.
+- Tightening the type immediately caught that
+  `collapse_drain_retry.committed` is a `number`, not a `boolean`.
+
+Acceptance criteria:
+- `Terminal` is a concrete union of query terminal reasons.
+- `Continue` is a concrete union of continuation reasons and payloads.
+- `bun run typecheck` validates all query return sites against that contract.
+
+## AUT-012: Avoid provider test settings-module mock pollution
+
+Type: Test Reliability
+Priority: P2
+Status: Draft
+Patch status: Implemented in `fix/autonomy-lifecycle`.
+
+Problem:
+The provider tests previously mocked `settings.js`. A minimal mock broke other
+tests that imported additional settings exports in the same Bun process; the
+expanded mock avoided the failure but over-coupled the provider test to
+unrelated settings internals.
+
+Evidence:
+- Full test runs observed cross-file settings mock pollution.
+- `src/utils/model/providers.ts` only needs the real `getInitialSettings()`
+  behavior.
+
+Acceptance criteria:
+- Provider tests do not mock `settings.js`.
+- `modelType` precedence is exercised through an injected settings snapshot,
+  leaving global bootstrap state untouched.
+- Provider tests pass when run alongside permissions tests and the provider
+  matrix.

+
+## 1. 图片处理无限内存增长 (v2.1.121)
+
+**CHANGELOG 描述**：Fixed unbounded memory growth (multi-GB RSS) when processing many images in a session
+
+### 实现位置
+
+- `src/utils/imageStore.ts` — 核心修复
+- `src/commands/clear/caches.ts` — 缓存清理
+- `src/screens/REPL.tsx` — UI 层释放
+
+### 修复方式
+
+三层防护机制：
+
+1. **LRU 内存缓存**：`storedImagePaths` Map 上限 200 条目（`MAX_STORED_IMAGE_PATHS`），超出自动驱逐最早条目
+2. **磁盘持久化**：图片 base64 数据写入 `~/.claude/image-cache/<sessionId>/`，内存中仅保留路径字符串
+3. **立即释放**：`setPastedContents({})` 在消息提交/命令执行后清空 React state 中的 base64 数据
+
+### 关键代码
+
+```typescript
+// imageStore.ts:10
+const MAX_STORED_IMAGE_PATHS = 200
+
+// imageStore.ts:115-124
+function evictOldestIfAtCap(): void {
+  while (storedImagePaths.size >= MAX_STORED_IMAGE_PATHS) {
+    const oldest = storedImagePaths.keys().next().value
+    if (oldest !== undefined) {
+      storedImagePaths.delete(oldest)
+    } else {
+      break
+    }
+  }
+}
+
+// imageStore.ts:129-167 — 清理旧会话目录
+export async function cleanupOldImageCaches(): Promise<void> { ... }
+```
+
+---
+
+## 2. /usage 命令泄漏约 2GB (v2.1.121)
+
+
+**CHANGELOG 描述**：Fixed /usage leaking up to ~2GB of memory on machines with large transcript histories
+
+### 实现位置
+
+- `src/utils/sessionStoragePortable.ts:716-792` — 核心流式读取
+- `src/utils/attribution.ts` — 调用方
+
+### 修复方式
+
+1. **分块流式读取**：使用 `TRANSCRIPT_READ_CHUNK_SIZE = 1MB` 固定块大小，通过 `fd.read()` 逐块处理，避免一次性加载整个 transcript
+2. **字节级过滤**：在 fd 层面直接跳过 `attribution-snapshot` 类型的行（占长会话 84% 的字节空间）
+3. **边界截断**：搜索 `compact_boundary` 标记，只保留边界之后的数据
+4. **缓冲区控制**：初始缓冲区限制 `Math.min(fileSize, 8MB)`
+
+### 关键代码
+
+```typescript
+// sessionStoragePortable.ts:716-792
+export async function readTranscriptForLoad(
+  filePath: string,
+  fileSize: number,
+): Promise<{
+  boundaryStartOffset: number
+  postBoundaryBuf: Buffer
+  hasPreservedSegment: boolean
+}> {
+  const s: LoadState = {
+    out: {
+      buf: Buffer.allocUnsafe(Math.min(fileSize, 8 * 1024 * 1024)),
+      len: 0,
+      cap: fileSize + 1,
+    },
+    // ...
+  }
+  const chunk = Buffer.allocUnsafe(CHUNK_SIZE)
+  const fd = await fsOpen(filePath, 'r')
+  try {
+    let filePos = 0
+    while (filePos < fileSize) {
+      const { bytesRead } = await fd.read(chunk, 0, Math.min(CHUNK_SIZE, fileSize - filePos), filePos)
+      if (bytesRead === 0) break
+      filePos += bytesRead
+      // ... 分块处理逻辑
+    }
+    finalizeOutput(s)
+  } finally {
+    await fd.close()
+  }
+}
+```
+
+---
+
+## 3. 长时间运行工具进度事件泄漏 (v2.1.121)
+
+
+**CHANGELOG 描述**：Fixed memory leak when long-running tools fail to emit a clear progress event
+
+### 实现位置
+
+- `src/screens/REPL.tsx:3054-3114` — progress 消息替换逻辑
+- `src/utils/sessionStorage.ts:186-196` — 临时消息类型定义
+
+### 修复方式
+
+1. **向后扫描替换**：从只检查最后一条消息改为向后遍历所有 progress 消息，找到匹配的 `parentToolUseID` + `type` 后替换（修复交错消息导致 13k+ 条目堆积）
+2. **全屏模式硬上限**：`MAX_FULLSCREEN_SCROLLBACK = 500`，超出截断
+3. **临时消息识别**：`isEphemeralToolProgress()` 区分 `bash_progress`、`sleep_progress` 等一次性消息与需要保留的 `agent_progress` 等
+
+### 关键代码
+
+```typescript
+// REPL.tsx:3094-3114
+setMessages(oldMessages => {
+  const newData = newMessage.data as Record<string, unknown>;
+  // Scan backwards to find the last ephemeral progress with matching
+  // parentToolUseID and type.
+  for (let i = oldMessages.length - 1; i >= 0; i--) {
+    const m = oldMessages[i]!
+    if (m.type !== 'progress') break
+    const mData = m.data as Record<string, unknown> | undefined
+    if (
+      m.parentToolUseID === newMessage.parentToolUseID &&
+      mData?.type === newData.type
+    ) {
+      const copy = oldMessages.slice();
+      copy[i] = newMessage;
+      return copy;
+    }
+  }
+  return [...oldMessages, newMessage];
+});
+
+// REPL.tsx:3058-3064 — 全屏模式硬上限
+const MAX_FULLSCREEN_SCROLLBACK = 500
+const kept = postBoundary.length > MAX_FULLSCREEN_SCROLLBACK
+  ? postBoundary.slice(-MAX_FULLSCREEN_SCROLLBACK)
+  : postBoundary
+return [...kept, newMessage]
+```
+
+---
+
+## 4. 空闲重新渲染循环 (v2.1.117)
+
+**状态：已确认完整**
+
+**CHANGELOG 描述**：Fixed idle re-render loop when background tasks are present, reducing memory growth on Linux
+
+### 实现位置
+
+- `packages/@ant/ink/src/components/ClockContext.tsx` — 核心时钟管理
+
+### 已实现部分
+
+`ClockContext` 的 `keepAlive` 订阅者分类机制完整存在：
+
+```typescript
+// ClockContext.tsx:11-43
+function createClock(tickIntervalMs: number): Clock {
+  const subscribers = new Map<() => void, boolean>()
+  let interval: ReturnType<typeof setInterval> | null = null
+
+  function updateInterval(): void {
+    const anyKeepAlive = [...subscribers.values()].some(Boolean)
+    if (anyKeepAlive) {
+      // 有 keepAlive 订阅者时启动 interval
+      interval = setInterval(tick, currentTickIntervalMs)
+    } else if (interval) {
+      // 无 keepAlive 订阅者时停止 interval
+      clearInterval(interval)
+      interval = null
+    }
+  }
+
+  return {
+    subscribe(onChange, keepAlive) {
+      subscribers.set(onChange, keepAlive)
+      updateInterval()
+      return () => {
+        subscribers.delete(onChange)
+        updateInterval()
+      }
+    },
+    // ...
+  }
+}
+```
+
+### 不确定部分
+
+无法确认 `useAnimationFrame` hook 是否在所有使用时钟的组件中正确传递了 `keepAlive` 参数。反编译代码中调用链可能不完整。
+
+---
+
+## 5. 虚拟滚动器保留历史消息拷贝 (v2.1.101)
+
+
+**CHANGELOG 描述**：Fixed a memory leak where long sessions retained dozens of historical copies of the message list in the virtual scroller
+
+### 实现位置
+
+- `src/components/VirtualMessageList.tsx:276-296`
+
+### 修复方式
+
+增量式键值数组：使用 `useRef` 保存 keys 数组引用，流式追加而非每次 O(n) 全量重建。
+
+```typescript
+// VirtualMessageList.tsx:276-296
+const keysRef = useRef<string[]>([])
+const prevMessagesRef = useRef<typeof messages>(messages)
+const prevItemKeyRef = useRef(itemKey)
+if (
+  prevItemKeyRef.current !== itemKey ||
+  messages.length < keysRef.current.length ||
+  messages[0] !== prevMessagesRef.current[0]
+) {
+  // 全量重建（仅在 itemKey 变化、数组缩短等场景）
+  keysRef.current = messages.map(m => itemKey(m))
+} else {
+  // 增量追加（正常流式场景）
+  for (let i = keysRef.current.length; i < messages.length; i++) {
+    keysRef.current.push(itemKey(messages[i]!))
+  }
+}
+prevMessagesRef.current = messages
+prevItemKeyRef.current = itemKey
+const keys = keysRef.current
+```
+
+修复前 27k 消息时每次新消息添加产生 ~1MB 内存分配，修复后降为 O(1) 追加。
+
+---
+
+## 6. 管道模式超宽行过度分配 (v2.1.110)
+
+
+**CHANGELOG 描述**：Fixed potential excessive memory allocation when piped (non-TTY) Ink output contains a single very wide line
+
+### 实现位置
+
+- `packages/@ant/ink/src/core/output.ts:200-207`
+
+### 修复方式
+
+在 `Output.reset()` 中当字符缓存超过 16384 条目时清空：
+
+```typescript
+// output.ts:200-207
+reset(width: number, height: number, screen: Screen): void {
+  this.width = width
+  this.height = height
+  this.screen = screen
+  this.operations.length = 0
+  resetScreen(screen, width, height)
+  if (this.charCache.size > 16384) this.charCache.clear()  // 关键修复
+}
+```
+
+---
+
+## 7. 语言语法按需加载 (v2.1.108)
+
+**状态：已修复**
+
+**CHANGELOG 描述**：Reduced memory footprint for file reads, edits, and syntax highlighting by loading language grammars on demand
+
+### 实现位置
+
+- `packages/color-diff-napi/src/index.ts:21-37`
+
+### 当前状态
+
+延迟加载逻辑**已被移除**，改为顶层静态导入。代码注释说明原因：
+
+```typescript
+// color-diff-napi/src/index.ts:21-37
+// Static import — createRequire(import.meta.url) fails in Bun --compile mode
+// because the resolved path points to the internal bunfs binary path where
+// node_modules cannot be found. A top-level import ensures the module is
+// bundled and accessible at runtime.
+import hljs from 'highlight.js'  // 顶层静态导入
+
+type HLJSApi = typeof hljs
+let cachedHljs: HLJSApi | null = null
+function hljsApi(): HLJSApi {
+  if (cachedHljs) return cachedHljs
+  const mod = hljs as HLJSApi & { default?: HLJSApi }
+  cachedHljs = 'default' in mod && mod.default ? mod.default : mod
+  return cachedHljs!
+}
+```
+
+**影响**：highlight.js 包含 190+ 语言语法（约 50MB），现在在模块加载时即全部载入内存，无法按需释放。这是为了兼容 Bun `--compile` 模式做的妥协。
+
+---
+
+## 8. NO_FLICKER 模式流状态泄漏 (v2.1.105)
+
+**状态：已修复**
+
+**CHANGELOG 描述**：Fixed a NO_FLICKER mode memory leak where API retries left stale streaming state
+
+### 实现位置
+
+- `src/screens/REPL.tsx:1841-1861` — `resetLoadingState()`
+- `src/screens/REPL.tsx:3568-3578` — finally 块调用
+
+### 已实现部分
+
+`resetLoadingState()` 在 `onQuery` 的 finally 块中无条件调用，清理 `streamingText`、`streamingToolUses` 等：
+

+## 9. Remote Control 权限条目保留 (v2.1.98)
+
+**状态：已修复**

+
+### 实现位置

+
+## 10. MCP HTTP/SSE 缓冲区累积 (v2.1.97)
+
+
+**CHANGELOG 描述**：Fixed MCP HTTP/SSE connections accumulating ~50 MB/hr of unreleased buffers when servers reconnect
+
+### 实现位置
+
+- `src/services/api/claude.ts:1557-1564` — `releaseStreamResources()`
+- `src/cli/transports/SSETransport.ts:419` — `reader.releaseLock()`
+- `@modelcontextprotocol/sdk` (sse.js, streamableHttp.js) — `response.body?.cancel()`
+
+### 修复方式
+
+1. **主动释放响应体**：`releaseStreamResources()` 清理 stream 和 response
+
+```typescript
+// claude.ts:1553-1564
+// Release all stream resources to prevent native memory leaks.
+// The Response object holds native TLS/socket buffers that live outside the
+// V8 heap (observed on the Node.js/npm path; see GH #32920), so we must
+// explicitly cancel and release it regardless of how the generator exits.
+function releaseStreamResources(): void {
+  cleanupStream(stream)
+  stream = undefined
+  if (streamResponse) {
+    streamResponse.body?.cancel().catch(() => {})
+    streamResponse = undefined
+  }
+}
+```
+
+2. **SSE 读取器释放**：
+
+```typescript
+// SSETransport.ts:418-419
+} finally {
+  reader.releaseLock()
+}
+```
+
+3. **MCP SDK 层面**：在所有 HTTP 路径（成功/失败/重连）调用 `response.body?.cancel()`

+## 11. LRU 缓存键保留大 JSON (v2.1.89)
+
+**状态：已确认完整实现**
+
+
+**CHANGELOG 描述**：Fixed memory leak where large JSON inputs were retained as LRU cache keys in long-running sessions
+
+### 实现位置
+
+- `src/utils/fileStateCache.ts:37-48` — 大小计算修复
+- `src/utils/queryHelpers.ts:48-54` — 类型强制转换
+
+### 修复方式
+
+1. **正确计算缓存大小**：处理 `content` 为嵌套对象的情况
+
+```typescript
+// fileStateCache.ts:37-48
+sizeCalculation: value => {
+  const c = value.content
+  const s =
+    typeof c === 'string'
+      ? c
+      : c === null || c === undefined
+        ? ''
+        : typeof c === 'object'
+          ? JSON.stringify(c)
+          : String(c)
+  return Math.max(1, Buffer.byteLength(s, 'utf8'))
+}
+```
+
+2. **强制类型转换**：确保 Write 工具 content 始终为字符串
+
+```typescript
+// queryHelpers.ts:48-54
+function coerceToolContentToString(value: unknown): string {
+  if (typeof value === 'string') return value
+  if (value === null || value === undefined) return ''
+  if (typeof value === 'object') return JSON.stringify(value)
+  return String(value)
+}
+```

+
+## 12. QueryEngine.mutableMessages 不收缩
+
+**状态：已修复**
+
+**代码注释描述**：`markers persist and re-trigger on every turn, and mutableMessages never shrinks (memory leak in long SDK sessions)`（`src/QueryEngine.ts:929-930`）
+
+### 实现位置
+
+- `src/services/compact/snipCompact.ts` — **存根文件**
+- `src/QueryEngine.ts:925-962` — 消息处理逻辑
+
+### 问题详情
+
+`mutableMessages` 数组只增不减，每轮对话 push 多条消息（assistant、progress、user、attachment 等）。清理依赖两条路径：
+
+**路径 1：API 返回 compact_boundary**（已实现）
+
+```typescript
+// QueryEngine.ts:946-962
+if (msg.subtype === 'compact_boundary' && msg.compactMetadata) {
+  const mutableBoundaryIdx = this.mutableMessages.length - 1
+  if (mutableBoundaryIdx > 0) {
+    this.mutableMessages.splice(0, mutableBoundaryIdx)  // 清理旧消息
+  }
+}
+```
+
+**路径 2：本地 snip 压缩**（存根 — 永不执行）
+
+```typescript
+// snipCompact.ts — 完整文件
+// Auto-generated stub — replace with real implementation
+export {};
+import type { Message } from 'src/types/message';
+
+export const isSnipMarkerMessage: (message: Message) => boolean = () => false;
+export const snipCompactIfNeeded: (
+  messages: Message[],
+  options?: { force?: boolean },
+) => { messages: Message[]; executed: boolean; tokensFreed: number; boundaryMessage?: Message } = (messages) => ({
+  messages,
+  executed: false,   // 永远 false — 清理从不执行
+  tokensFreed: 0,
+});
+export const isSnipRuntimeEnabled: () => boolean = () => false;
+export const shouldNudgeForSnips: (messages: Message[]) => boolean = () => false;
+export const SNIP_NUDGE_TEXT: string = '';
+```
+
+`snipReplay` 回调依赖 `HISTORY_SNIP` feature flag，且调用的 `snipCompactIfNeeded` 永远返回 `executed: false`。
+
+```typescript
+// QueryEngine.ts:933-942
+const snipResult = this.config.snipReplay?.(msg, this.mutableMessages)
+if (snipResult !== undefined) {
+  if (snipResult.executed) {       // 永远是 false
+    this.mutableMessages.length = 0
+    this.mutableMessages.push(...snipResult.messages)
+  }
+  break
+}
+```
+
+### 风险评估
+
+- 在长时间 SDK 会话中，如果 API 不频繁返回 `compact_boundary`，`mutableMessages` 会持续增长
+- 每条消息可能包含大量内容（工具输出、文件内容等），长时间运行可能导致 GB 级内存占用
+- 这是当前代码库中**最明确的未实现内存泄漏点**
+
+---
+
+## 17. LSP Opened Files Map 不收缩
+
+**状态：已修复**
+
+**代码注释描述**：`closeFile()` 存在但未与 compact 流程集成（`LSPServerManager.ts:373-375` 显式标注为 TODO）
+
+### 实现位置
+
+- `src/services/lsp/LSPServerManager.ts:414-428` — `closeAllFiles()` 方法
+- `src/services/compact/postCompactCleanup.ts:81-88` — 集成调用
+
+### 问题详情
+
+`LSPServerManager` 中的 `openedFiles: Map<string, string>` 追踪所有通过 `didOpen` 打开的文件。`closeFile()` 方法存在可以发送 `didClose` 通知并清理 Map 条目，但代码注释明确标注：
+
+```
+NOTE: Currently available but not yet integrated with compact flow.
+TODO: Integrate with compact - call closeFile() when compact removes files from context
+```
+
+长时间会话中，每次读取/编辑文件都会通过 `openFile()` 添加条目，但 compaction 不会清理这些条目，导致 Map 无限增长。
+
+### 修复方式
+
+1. **添加 `closeAllFiles()` 方法**：遍历 `openedFiles` Map，对每个文件发送 `didClose` 通知，然后清空 Map。Best-effort 错误处理。
+
+```typescript
+async function closeAllFiles(): Promise<void> {
+  const entries = [...openedFiles.entries()]
+  openedFiles.clear()
+  for (const [fileUri, serverName] of entries) {
+    const server = servers.get(serverName)
+    if (!server || server.state !== 'running') continue
+    try {
+      await server.sendNotification('textDocument/didClose', {
+        textDocument: { uri: fileUri },
+      })
+    } catch {
+      // Best-effort — server may have stopped
+    }
+  }
+}
+```
+
+2. **集成到 `postCompactCleanup`**：在 compaction 后自动调用 `closeAllFiles()`，释放所有 LSP 服务器端的文件状态。
+
+```typescript
+// postCompactCleanup.ts
+try {
+  const lspManager = getLspServerManager()
+  if (lspManager) {
+    await lspManager.closeAllFiles()
+  }
+} catch {
+  // LSP module may not be available in all environments
+}
+```
+

+# VSCode IDE Bridge Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** 为当前 CLI 增加一个可运行的 VSCode `ws-ide` 扩展端实现，让 `/ide`、选区上下文注入和 IDE diff 预览在本地 VSCode 中可用。
+
+**Architecture:** 在仓库中新增独立的 VSCode 扩展包，扩展在本地启动 WebSocket IDE Bridge，并通过 lockfile 让 CLI 自动发现。扩展在该连接上暴露一个 MCP Server，负责发送 `selection_changed` / `ide_connected` 通知，并实现 `openDiff`、`close_tab`、`closeAllDiffTabs` 这几个 CLI 已使用的 MCP tools。
+
+**Tech Stack:** TypeScript、VSCode Extension API、WebSocket、`@modelcontextprotocol/sdk`、Node.js 文件系统 API
+
+> 说明：执行前已校正协议边界。这里的 `openDiff` / `close_tab` / `closeAllDiffTabs` 不是自定义裸 WebSocket RPC，而是通过 MCP tool 调用完成；`selection_changed` / `ide_connected` 才是扩展主动发往 CLI 的通知。

+# VSCode IDE Bridge 设计文档
+
+**日期：** 2026-04-07
+
+## 1. 背景
+
+当前仓库已经具备一套较完整的 IDE 接入链路：
+
+- CLI 能发现 `ws-ide` / `sse-ide` 类型的 IDE 连接
+- CLI 能接收 `selection_changed` 并将其注入为 `<ide_selection>` 上下文
+- CLI 能调用 `openDiff`、`close_tab`、`closeAllDiffTabs` 等 IDE RPC
+- `/ide`、diff 预览、选区提示、已打开文件提示都依赖这套链路
+
+但当前仓库中没有可直接使用的 VSCode 扩展实现，导致本地 VSCode 无法真正把这些能力提供给 CLI。目标不是重做一个聊天面板，而是补齐一个兼容现有 CLI 协议的 VSCode 扩展，让 CLI “像连接到原生 IDE 扩展一样”工作。
+
+## 2. 目标
+
+构建一个独立的 VSCode 扩展，在本地暴露一个与当前 CLI 兼容的 `ws-ide` 服务，完成以下能力：
+
+1. 让 CLI 能自动发现 VSCode
+2. 让 VSCode 当前文件和选区变化能进入 CLI 的 IDE 上下文链路
+3. 让 CLI 发起的 diff 预览能在 VSCode 中打开和关闭
+4. 保持实现最小、可调试、可逐步扩展
+
+## 3. 非目标
+
+第一版明确不做以下内容：
+
+- 不实现 VSCode 聊天面板
+- 不接入远程工作区、Codespaces、Dev Container、SSH Remote
+- 不兼容多台机器之间的桥接
+- 不实现复杂的会话恢复或扩展端持久化缓存
+- 不覆盖官方扩展的所有功能
+
+## 4. 总体方案
+
+采用“独立 sidecar 扩展 + 本地 WebSocket IDE Bridge”的方式。
+
+### 4.1 连接模型
+
+VSCode 扩展启动后：
+
+1. 在 `127.0.0.1` 上启动一个随机可用端口的 WebSocket 服务
+2. 生成与 CLI 现有 IDE 发现逻辑兼容的 lockfile
+3. 等待 CLI 以 `ws-ide` MCP 客户端身份连接
+4. 扩展在该 WebSocket 连接上暴露 MCP Server，负责把 IDE 事件推送给 CLI，并响应 CLI 发来的 MCP tool 调用
+
+### 4.2 复用现有 CLI 能力
+
+扩展尽量不改 CLI 的上层交互，只复用现有协议：
+
+- VSCode -> CLI：`selection_changed`、`ide_connected` 通知
+- CLI -> VSCode：通过 MCP tool 调用 `openDiff`、`close_tab`、`closeAllDiffTabs`
+
+这样可以最大化复用：
+
+- `src/hooks/useIdeSelection.ts`
+- `src/utils/attachments.ts`
+- `src/utils/messages.ts`
+- `src/hooks/useDiffInIDE.ts`
+- `/ide` 命令及 IDE 状态展示
+
+## 5. 协议设计
+
+### 5.1 Lockfile
+
+扩展写出的 lockfile 需要满足 CLI 的 IDE 自动发现逻辑。内容至少包含：
+
+- `workspaceFolders`
+- `pid`
+- `ideName`
+- `transport: "ws"`
+- `runningInWindows`
+- `authToken`
+
+文件名使用端口号，例如 `<port>.lock`。
+
+### 5.2 鉴权
+
+扩展启动时生成一次随机 `authToken`：
+
+- 写入 lockfile
+- CLI 连接 `ws-ide` 时通过 `X-Claude-Code-Ide-Authorization` 头带上
+- 扩展端校验成功后才允许建立 MCP/WebSocket 会话
+
+第一版只允许本地回环地址，不暴露到公网。
+
+### 5.3 VSCode -> CLI 通知
+
+#### `selection_changed`
+
+在下列事件触发后发送：
+
+- `window.onDidChangeTextEditorSelection`
+- `window.onDidChangeActiveTextEditor`
+- 扩展激活完成后的初始同步
+
+消息字段包含：
+
+- `selection.start.line`
+- `selection.start.character`
+- `selection.end.line`
+- `selection.end.character`
+- `text`
+- `filePath`
+
+若当前没有活动选区：
+
+- `selection` 允许为 `null`
+- 仍尽量发送 `filePath`
+
+这样 CLI 至少可以知道“用户当前打开的是哪个文件”。
+
+### 5.4 CLI -> VSCode MCP tools
+
+#### `openDiff`
+
+入参：
+
+- `old_file_path`
+- `new_file_path`
+- `new_file_contents`
+- `tab_name`
+
+行为：
+
+- 读取当前磁盘文件内容作为左侧内容
+- 使用临时文档或内存文档构造右侧内容
+- 在 VSCode 中打开 diff 视图
+- 记录 `tab_name -> 资源引用` 映射
+
+#### `close_tab`
+
+入参：
+
+- `tab_name`
+
+行为：
+
+- 根据映射关闭对应 diff 视图
+- 清理映射与临时资源
+
+#### `closeAllDiffTabs`
+
+行为：
+
+- 关闭所有由本扩展打开的 diff 标签
+- 清理内部状态
+
+## 6. 扩展内部结构
+
+建议新增独立包：`packages/vscode-ide-bridge`
+
+目录结构如下：
+
+```text
+packages/vscode-ide-bridge/
+  package.json
+  tsconfig.json
+  src/
+    extension.ts
+    server/
+      bridgeServer.ts
+      lockfile.ts
+      workspaceInfo.ts
+      selectionPublisher.ts
+      diffController.ts
+      protocol.ts
+    util/
+      randomToken.ts
+      disposables.ts
+  test/
+    selectionPublisher.test.ts
+    lockfile.test.ts
+    bridgeServer.test.ts
+    diffController.test.ts
+```
+
+各模块职责如下：
+
+- `extension.ts`
+  VSCode 扩展入口，负责激活、停用、启动 bridge、注册命令。
+
+- `bridgeServer.ts`
+  本地 WebSocket 服务与消息路由层，负责握手、鉴权、连接管理，以及把单个 WebSocket 连接桥接为 MCP transport。
+
+- `lockfile.ts`
+  负责写 lockfile、更新 lockfile、删除 lockfile。
+
+- `workspaceInfo.ts`
+  负责采集工作区目录、平台信息、活动编辑器文件路径。
+
+- `selectionPublisher.ts`
+  监听 VSCode 编辑器事件，并把选区信息转换为 `selection_changed`。
+
+- `diffController.ts`
+  处理 `openDiff` / `close_tab` / `closeAllDiffTabs` 这三个 MCP tools，维护临时资源和 tab 映射。
+
+- `protocol.ts`
+  统一定义扩展端需要识别和发送的消息结构，避免字符串散落。
+
+## 7. 命令与可观察性
+
+虽然主流程是自动连接，但第一版仍建议提供两个调试命令：
+
+- `Claude Code Bridge: Restart`
+- `Claude Code Bridge: Show Status`
+
+状态信息至少包含：
+
+- 当前监听端口
+- lockfile 路径
+- 是否有 CLI 已连接
+- 当前工作区数量
+- 最近一次选区推送时间
+
+另外建议注册一个 output channel：
+
+- `Claude Code IDE Bridge`
+
+用于输出：
+
+- 启动日志
+- 鉴权失败
+- lockfile 写入失败
+- diff 打开失败
+- 连接断开原因
+
+## 8. 错误处理策略
+
+### 8.1 端口占用
+
+- 自动尝试新的随机端口
+- 更新 lockfile
+- 在 output channel 中记录端口变化
+
+### 8.2 lockfile 写入失败
+
+- bridge 不进入 ready 状态
+- 弹出 VSCode 错误通知
+- output channel 记录完整错误
+
+### 8.3 WebSocket 鉴权失败
+
+- 拒绝连接
+- 记录远端地址和失败原因
+
+### 8.4 活动编辑器为空
+
+- 发送空选区状态或仅跳过通知
+- 不抛异常、不打断 bridge 生命周期
+
+### 8.5 diff 打开失败
+
+- 返回明确错误结果给 CLI
+- 不留下半开的临时资源
+
+### 8.6 扩展退出
+
+- 关闭 WebSocket server
+- 删除 lockfile
+- 释放临时文档资源
+- 清空 tab 映射
+
+## 9. 测试方案
+
+### 9.1 单元测试
+
+覆盖以下逻辑：
+
+- lockfile 内容生成与路径选择
+- 选区对象到协议消息的转换
+- tab 映射和关闭逻辑
+- 鉴权令牌校验
+
+### 9.2 集成测试
+
+通过 Node/WebSocket 客户端模拟 CLI：
+
+- 连接本地 bridge server
+- 验证鉴权成功与失败
+- 验证 `selection_changed` 是否按预期发送
+- 验证 `openDiff` / `close_tab` 是否触发预期行为
+
+### 9.3 手工验证
+
+手工验证路径：
+
+1. 启动 VSCode 扩展
+2. 启动 `claude-code-best`
+3. 执行 `/ide`
+4. 确认 CLI 能识别到 VSCode
+5. 在 VSCode 中选中一段代码并提问
+6. 确认 CLI 能注入 `<ide_selection>`
+7. 触发一次 IDE diff
+8. 确认 diff 标签可打开、保存、关闭
+
+## 10. 风险与取舍
+
+### 10.1 MCP 完整兼容风险
+
+仓库当前 CLI 连接 `ws-ide` 时使用的是 MCP 客户端通路，因此扩展端若实现过薄，可能在握手或工具注册阶段与 CLI 预期不一致。
+
+**取舍：**
+第一版只实现 CLI 当前实际会调用到的最小工具与通知，不尝试泛化为完整 MCP server，但协议层要留出扩展空间。
+
+### 10.2 VSCode diff 资源回收
+
+VSCode diff 视图不是纯命名 tab，直接按 `tab_name` 定位关闭可能和实际标签生命周期有偏差。
+
+**取舍：**
+扩展内部维护显式映射，以资源 URI 为主、`tab_name` 为辅，不依赖 UI 文本匹配。
+
+### 10.3 多工作区与路径兼容
+
+Windows、WSL、单根工作区、多根工作区在路径表示上会不同。
+
+**取舍：**
+第一版先以本机本地工作区为主，路径统一走绝对路径；WSL/Windows 转换尽量复用 CLI 现有约定，不在扩展端重新发明路径映射。
+
+## 11. 分阶段交付
+
+### 第一阶段
+
+目标：打通本地 VSCode 与 CLI 的最小闭环。
+
+范围：
+
+- 启动 `ws-ide`
+- 写 lockfile
+- 发送 `selection_changed`
+- 实现 `openDiff`
+- 实现 `close_tab`
+- 实现 `closeAllDiffTabs`
+- 提供状态命令和日志输出
+
+### 第二阶段
+
+目标：增强稳定性和调试能力。
+
+范围：
+
+- 更细的错误提示
+- 更稳定的 tab 生命周期管理
+- 更多 IDE 状态信息展示
+- 更完整的集成测试
+
+## 12. 结论
+
+推荐按本设计实现独立的 VSCode IDE Bridge 扩展，并让它完全对齐当前 CLI 已有的 `ws-ide` 连接与 IDE 上下文/差异视图协议。这样能在不大改 CLI 上层逻辑的前提下，把 VSCode 选区、当前文件和 diff 预览能力真正打通。
