 ### Added
 
+- **Claude Code Release A 自动闭环**：新增 Agent Reporter、Governed Launcher、
+  Claude Hooks Adapter 与受治理 launch context。Codex 可派发一个或多个真实
+  Claude Code Agent，并通过 Coordination Journal、Notification Pump 和官方
+  Codex App Server 在原主对话接收进展、阻塞、失败和待审核事件。
+- **受治理子进程生命周期**：新增 fenced lease 周期续租、journal-only
+  heartbeat、显式 handoff 终态保护、异常/超时恢复、最终 lease release 和脱敏
+  child receipt。
+- **启动持久化握手**：Launcher 在 `task.accepted` 持久化后才允许 monitor
+  访问 Journal，避免 launcher/monitor 并发写入造成 hash-chain 竞争。
 - 新增 `cortex-agent secrets <store|verify|list|audit>` 公共命令，通过项目
   Secrets skill 使用 macOS Keychain 等后端；`store` 仅接受
   `--from-env`，`verify --provider npm` 只返回认证身份，不输出凭证。

+- Agent Reporter 的 ownership、identity、project 和 notification target 只从
+  私有受治理上下文和 Task 快照取得，Agent 参数不能覆盖治理字段。

+//
+// Bridges Claude Code hooks to the coordination machine. The adapter enforces
+// governance: every hook payload is validated, redacted, and rate-limited before
+// it reaches the Coordination Application Service.
+//
+// Architecture:
+//   claude-hook-adapter.js      — factory, dispatch, entry point (this file)
+//   claude-hook-handlers.js     — individual hook handler functions
+//   claude-hook-redaction.js    — redaction, secret scan, evidence validation
+//   claude-hook-rate-limiter.js — rate limiting, progress merging
+//
+// Hook mapping (P-003 §11.2):
+//   SessionStart      → task.accepted    (reporter route, idempotent)
+//   PostToolUse       → task.progress    (rate-limited, merged)
+//   TestStart         → task.testing     (only when signal matches)
+//   Notification      → task.input_required (bounded metadata only)
+//   Permission        → task.input_required (bounded metadata only)
+//   ReadyForReview    → task.ready_for_review (allowed evidence only)
+//   Stop              → NEVER infer completion
+//   SubagentStop      → NEVER infer completion
+//
+// Safety contract:
+//   - SessionStart validates CORTEX_LAUNCH_CONTEXT before accepting
+//   - PostToolUse is rate-limited (max 1 per N ms) and merged into one update
+//   - PostToolUse with "test" signal mapping maps to task.testing
+//   - Notification/Permission strips raw payload, only passes requestedAction
+//   - ReadyForReview only accepts evidence refs from the allowed set
+//   - Stop/SubagentStop never emit task.completed or task.failed
+//   - All hook payloads are scanned for credentials, paths, prompts, commands
+//   - Unknown hook names are silently ignored (fail closed)

+// ─── Governed Launcher (T-ACN-016) ───────────────────────────────────────────
+//
+// Launches a governed agent with a private launch context and manages the
+// agent lifecycle through the public Task API.
+//
+// A governed launch produces:
+//   1. A private launch context object (never shared, never persisted in public).
+//   2. A task.created event through the Coordination Application Service.
+//   3. A task.assigned event that assigns the task to the target agent.
+//   4. A task.accepted event only AFTER the subprocess is successfully spawned.
+//   5. A task.failed event if the subprocess cannot be spawned.
+//   6. A structured launch result with minimal public fields.
+//
+// The launch context is private to the launching process — it is never
+// written to disk, never serialized to a public receipt, and never echoed in a
+// delivery result. The launched agent receives only what it needs via a
+// private temp file or restricted FD.
+//
+// Safety contract:
+//   - launch() validates agentCommand (no fallback, no relative path, no
+//     non-executable, no injection chars, optional whitelist) before
+//     creating/assigning the task.
+//   - agentArgs are validated (array, max length, no NUL).
+//   - Task is created and assigned BEFORE worktree/ownership validation,
+//     so that all launch failures produce a real task.failed event.
+//   - Subprocess creation is delegated to an injectable executor (for testing).
+//   - The launch context is frozen at creation and discarded after launch.
+//   - Private launch context fields are NEVER exposed in the public result.
+//   - No automatic dispatch/daemon: the caller must explicitly invoke launch().
+//   - Only task.accepted is emitted after the subprocess is confirmed alive.
+//   - A real launch failure emits task.failed — never a fake accepted.
+//   - service.submit failures are NOT silently swallowed — they are reported
+//     in the result.
+//   - agentCommand/agentArgs are ONLY in the private context, NEVER in the
+//     public result, event, receipt, or bridge output.

+// ─── Generic Host Event Bridge (T-ACN-016) ───────────────────────────────────
+//
+// Bridges lifecycle events from a generic host to the Coordination Application
+// Service. The bridge operates under a governed launch context — it reads the
+// agent identity (actorId, taskId, projectId, sessionId) from the private
+// CORTEX_LAUNCH_CONTEXT file. Without a valid context, the bridge fails closed.
+//
+// The bridge exposes a single restricted CLI surface:
+//   cortex-agent agent report --event-type <type> [--message <text>]
+//     [--evidence-ref <ref>] [--notification-policy <policy>]
+//
+// The CLI does NOT accept governance parameters (actor-id, project-id, task-id,
+// kind, session-id, correlation-id, event-json). All unknown options are
+// rejected. The action is restricted to agent-scoped lifecycle event types.
+//
+// Safety contract:
+//   1. Only agent-scoped event types are accepted.
+//   2. Governance fields are read from CORTEX_LAUNCH_CONTEXT, never from CLI.
+//   3. Unknown CLI options are rejected (not silently dropped).
+//   4. The bridge never writes to disk, spawns processes, or makes network
+//      calls. All side effects are delegated to the Coordination Application
+//      Service.
+//   5. No automatic dispatch/daemon: the bridge is purely reactive.
+//   6. Fail closed: no valid governed context = bridge error.
+//   7. Raw JSON event envelopes (--event-json) are NEVER accepted.

+# Hook Adapter: Claude Code Governance (T-ACN-017)
+
+## Overview
+The Claude Code Hook Adapter bridges Claude Code hooks to the Coordination Machine, enforcing governance over the agent lifecycle. Every hook payload is validated, redacted, and rate-limited before reaching the coordination service.
+
+## Hook Mapping
+
+| Hook Name | Coordination Event | Notes |
+|-----------|-------------------|-------|
+| `SessionStart` | `task.accepted` | Only through real launcher (CORTEX_LAUNCH_CONTEXT required) |
+| `PostToolUse` | `task.progress` | Rate-limited (5000ms window), merged within window |
+| `TestStart` | `task.testing` | Auto-detected from test signal (npm test, vitest, jest, etc.) |
+| `Notification` | `task.input_required` | Raw payload stripped; only requestedAction forwarded |
+| `Permission` | `task.input_required` | Raw payload stripped; only requestedAction forwarded |
+| `ReadyForReview` | `task.ready_for_review` | Only allowed evidence refs forwarded |
+| `Stop` | — | NEVER infers completion; coordinator determines terminal state |
+| `SubagentStop` | — | NEVER infers completion; coordinator determines terminal state |
+
+## Safety Contract
+1. **Fail closed**: Unknown hook names are silently ignored.
+2. **Redaction**: prompt, session, path, command, tool payload, and credentials are always redacted.
+3. **Rate limiting**: PostToolUse is limited to 1 emission per 5000ms per tool name.
+4. **Test signal**: PostToolUse with test commands (npm test, vitest, jest, node --test, etc.) maps to `task.testing`.
+5. **Evidence validation**: Only evidence refs matching allowed patterns (ARTIFACT-*, RUN-*, ./relative, src/, lib/, tests/, docs/) are forwarded.
+6. **No completion inference**: Stop and SubagentStop never emit `task.completed` or `task.failed`.
+
+## Integration
+The adapter is available at `lib/coordination/claude-hook-adapter.js`. Create an instance with `createClaudeHookAdapter({ rateLimitMs })` and dispatch hook payloads via `adapter.dispatch(hookName, payload)`. Each handler returns a structured result with `ok`, `code`, and `eventType` fields.
+
+## Hook Executable
+The governed hook executable is at `bin/cortex-claude-hook`. It accepts a hook name as the first argument and bounded JSON from stdin. Identity is derived exclusively from `CORTEX_LAUNCH_CONTEXT`. Governance fields in stdin are rejected.
+
+### Claude Code Settings
+To wire the governed hooks into Claude Code, add the hooks from `.agent/hooks/claude-governed-hooks.json` to your `~/.claude/settings.json` or project `.claude/settings.json`:
+
+```bash
+# Install the hook executable (or link locally)
+cortex-agent bin/cortex-claude-hook is available in the package bin directory.
+```
+
+The settings use `npx --yes cortex-claude-hook` to invoke the executable without hard-coded absolute paths. Each hook is routed to the corresponding handler, with identity derived from `CORTEX_LAUNCH_CONTEXT`.

+# 钩子适配器：Claude Code 治理 (T-ACN-017)
+
+## 概述
+Claude Code 钩子适配器将 Claude Code 钩子桥接到协调机器，对代理生命周期执行治理。每个钩子负载在到达协调服务之前都会经过验证、脱敏和限速处理。
+
+## 钩子映射
+
+| 钩子名称 | 协调事件 | 说明 |
+|---------|---------|------|
+| `SessionStart` | `task.accepted` | 仅通过真实启动器（需要 CORTEX_LAUNCH_CONTEXT）|
+| `PostToolUse` | `task.progress` | 限速（5000ms 窗口），窗口内合并 |
+| `TestStart` | `task.testing` | 从测试信号自动检测（npm test、vitest、jest 等）|
+| `Notification` | `task.input_required` | 原始负载被剥离；仅转发 requestedAction |
+| `Permission` | `task.input_required` | 原始负载被剥离；仅转发 requestedAction |
+| `ReadyForReview` | `task.ready_for_review` | 仅转发允许的证据引用 |
+| `Stop` | — | 永不推断完成；协调器决定终止状态 |
+| `SubagentStop` | — | 永不推断完成；协调器决定终止状态 |
+
+## 安全契约
+1. **失败关闭**：未知钩子名称被静默忽略。
+2. **脱敏**：prompt、session、path、command、tool payload 和凭据始终被脱敏。
+3. **限速**：PostToolUse 每个工具名称每 5000ms 限制 1 次发射。
+4. **测试信号**：带有测试命令（npm test、vitest、jest、node --test 等）的 PostToolUse 映射到 `task.testing`。
+5. **证据验证**：仅转发匹配允许模式（ARTIFACT-*、RUN-*、./relative、src/、lib/、tests/、docs/）的证据引用。
+6. **不推断完成**：Stop 和 SubagentStop 永不发射 `task.completed` 或 `task.failed`。
+
+## 集成
+适配器位于 `lib/coordination/claude-hook-adapter.js`。使用 `createClaudeHookAdapter({ rateLimitMs })` 创建实例，并通过 `adapter.dispatch(hookName, payload)` 分发钩子负载。每个处理程序返回一个包含 `ok`、`code` 和 `eventType` 字段的结构化结果。
+
+## 钩子可执行文件
+受治理的钩子可执行文件位于 `bin/cortex-claude-hook`。它接受钩子名称作为第一个参数，并从 stdin 读取有界 JSON。身份完全从 `CORTEX_LAUNCH_CONTEXT` 派生。stdin 中的治理字段将被拒绝。
+
+### Claude Code 配置
+要将受治理的钩子接入 Claude Code，请将 `.agent/hooks/claude-governed-hooks.json` 中的钩子配置添加到 `~/.claude/settings.json` 或项目 `.claude/settings.json`：
+
+```bash
+# 安装钩子可执行文件（或本地链接）
+cortex-agent bin/cortex-claude-hook 在包的 bin 目录中可用。
+```
+
+配置使用 `npx --yes cortex-claude-hook` 调用可执行文件，无需硬编码绝对路径。每个钩子路由到相应的处理程序，身份从 `CORTEX_LAUNCH_CONTEXT` 派生。

+//
+// These tests invoke the actual hook executable (`bin/cortex-claude-hook`) against
+// a real CoordinationApplicationService and Journal in a temp project directory.
+//
+// Coverage:
+//   1. SessionStart — validates governed context, no event submitted (launcher authoritative)
+//   2. PostToolUse — submits task.progress event to Journal
+//   3. PostToolUse with test signal — submits task.testing to Journal
+//   4. Notification — submits task.input_required to Journal
+//   5. Permission — submits task.input_required to Journal
+//   6. ReadyForReview — submits task.ready_for_review with evidence to Journal
+//   7. Stop — nonterminal, never submits events
+//   8. SubagentStop — nonterminal, never submits events
+//   9. Governance field rejection in stdin
+//  10. Unknown field rejection in stdin (hook-specific schema)
+//  11. Unknown hook name rejection
+//  12. Receipt never leaks sensitive data (prompt, session, path, token, credentials)
+//  13. No duplicate accepted on SessionStart
+//  14. Notification Pump compatibility (event format in Journal)

+//
+// These tests invoke the `cortex-agent hook claude <HookName>` CLI command
+// against a real CoordinationApplicationService and Journal in a temp project
+// directory. They verify that the hook CLI routes through the Agent Reporter
+// (never direct createEvent/submit) and produces correct redacted receipts.
+//
+// Coverage:
+//   1. SessionStart — validates governed context, no event submitted (launcher authoritative)
+//   2. PostToolUse — submits task.progress via Agent Reporter
+//   3. PostToolUse with test signal — submits task.testing via Agent Reporter
+//   4. Notification — submits task.input_required via Agent Reporter
+//   5. Permission — submits task.input_required via Agent Reporter
+//   6. ReadyForReview — submits task.ready_for_review with evidence via Agent Reporter
+//   7. Stop — nonterminal, never submits events
+//   8. SubagentStop — nonterminal, never submits events
+//   9. Governance field rejection in stdin
+//  10. Unknown field rejection in stdin (hook-specific schema)
+//  11. Unknown hook name rejection
+//  12. Receipt never leaks sensitive data
+//  13. No duplicate accepted on SessionStart
+//  14. Notification Pump compatibility (event format in Journal)
+//  15. Error receipt safety
