fix(executor): debug 输出 LLM 实际回复的前200字

之前只输出 💬 text，看不到 LLM 实际说了什么。
现在 stderr 会显示 LLM 回复前200字符，可以通过 checkpoint
找到完整文本。

+## 0. 审计总览
+
+| 严重程度 | 数量 | 说明 |
+|---|---|---|
+| CRITICAL | 31 | 架构性缺陷，阻塞核心不变量或导致运行时崩溃 |
+| HIGH | 22 | 功能性缺陷，子系统与设计断连或关键逻辑缺失 |
+| MEDIUM | 19 | 部分实现偏差，影响完整性但不阻塞骨架 |
+| LOW | 12 | 命名/结构偏差、多余类型、文档注释问题 |
+
+**总体评估:** 代码骨架覆盖了 V1.0.0 Alpha 的 8 个阶段目标，monorepo 结构、包分层、SQLite schema、事件注册表均存在。但实现与设计文档之间存在大量结构性偏差，核心子系统（Scheduler 状态机、IPC 协议、安全模型、上下文装配）与冻结基线的匹配度不足 40%。当前代码属于 **Phase 0-1 骨架 + Phase 2-7 桩代码** 状态，多数子系统有类无逻辑或有逻辑但语义不匹配。

+## 2. 契约包审计 (packages/contracts vs interface-contracts-v1.md)
+
+### 2.1 缺失的契约接口 (15 个)
+
+| # | 契约名 | 设计位置 | 严重程度 |
+|---|---|---|---|
+| 1 | `EventBus` | SS7 | CRITICAL |
+| 2 | `EventStore` | SS7 | CRITICAL |
+| 3 | `EventIngestor` | SS7 | CRITICAL |
+| 4 | `ContextAssembler` | SS16 | CRITICAL |

+| 13 | `AssembledContext` | SS16 | HIGH |
+| 14 | `CompactionPolicy` | SS16 | HIGH |
+| 15 | `CompactionResult` | SS16 | HIGH |
+
+### 2.2 字段级偏差
+
+| 契约 | 字段 | 设计 | 代码 | 文件:行 |
+|---|---|---|---|---|
+| `ProviderCapabilityMatrix` | `supports` | `JsonObject` | `ProviderSupports` (强类型) | provider.ts:70 |
+| `ProviderCapabilityMatrix` | `conversion` | `JsonObject` | `ProviderConversion` (强类型) | provider.ts:71 |
+| `ProviderCapabilityMatrix` | (额外字段) | 不存在 | `display_name?`, `limits?`, `default_use?`, `notes?` | provider.ts:64,72-74 |
+| `ModelRequirement` | `required` | `JsonObject` | `Partial<ProviderSupports>` | provider.ts:146 |
+| `ProviderManager` | (额外方法) | 不存在 | `load_config(): Promise<void>` | provider.ts:277 |
+| `DoctorIssueSeverity` | (缺失值) | 包含 `"error"` | 缺少 `"error"` | platform.ts:41 |
+| `TaskGraph` | `dependencies` | `TaskDependencyRecord[]` | 内联结构等价物 | task.ts:147 |
+| `PromptLayerLoader` | 参数类型 | `ProjectContext`, `TaskSpec` | 内联结构子集 | runtime.ts:94-104 |
+
+### 2.3 多余契约 (需 ADR)
+
+`ProviderIdentity`, `ProviderConversionReport`, `ProviderLimits`, `ProviderDefaultUse`, `DoctorIssue`, `DoctorIssueCategory`, `ToolErrorOutput` (来自 error-taxonomy-v1.md 但未实现) 等均为代码中新增但设计文档中不存在的契约。
+
+---
+
+## 3. 存储层审计 (packages/runtime/src/storage/ vs db-schema-v1.md)
+
+### 3.1 会话 DB Schema: 完整 (PASS)
+
+17 个表、38 个索引、3 个 PRAGMA、5 个 schema_meta 种子键全部正确匹配。
+
+### 3.2 CRITICAL 发现
+
+**F-01: DebugKnowledgeStore schema 完全不匹配 db-schema-v1.md §20.1**
+- DB 路径: 代码 `.air/shared/debug-records.db` vs 设计 `.air/local/debug-records.db`
+- 7 个列名/语义不匹配: `failure_signature` → `signature`, `fix_ref` → `fix_applied`, 缺失 `summary`/`evidence_json`/`verification_json`/`updated_at`/`metadata_json`
+- 多余列: `session_id`, `error_kind`, `status`, `resolved_at`
+- 索引名不匹配
+
+**F-02: LearnedMemoryStore schema 完全不匹配 db-schema-v1.md §20.2**
+- DB 路径: 代码 `.air/shared/learned-memory.db` vs 设计 `.air/local/learned-memory.db`
+- 表名: 代码 `learned_memory` vs 设计 `learned_memories`
+- 6 个列名/语义不匹配
+- 枚举值完全不匹配: 设计 `project_rule|toolchain_rule|skill_update|debug_experience` vs 代码 `pattern|rule|skill|experience`
+- 状态枚举不匹配: 设计 `candidate|promoted|archived|rejected` vs 代码 `draft|promoted|archived`
+
+**F-04: EventStore.project() 未将事务句柄传递给仓库**
+- `append()` 正确开启事务，但 `project()` 方法接收 `_tx` 参数后从不传给仓库方法
+- 违反 db-schema-v1.md §1 规则 8: "持久事件插入与域表更新必须在同一事务中"
+- 影响: 域表写入失败时事件行仍会提交，造成不一致状态
+
+**F-05: EventStore 写入无效的 workspace status 值**
+- `workspace.created` 写入 `status: 'created'`，但有效枚举为 `active|merged|conflicted|abandoned|cleaned`
+- `workspace.merge.started` 写入 `status: 'merging'`，不在枚举中
+- 导致 `assertEnumValues` 抛出 AirError，**首次 workspace 创建即崩溃**
+
+**F-06: TaskAttemptRepository.update() 列映射 bug**
+- 检查 `patch.failure_signature` 但更新 `failure_summary` 列
+- 导致 `failure_signature` 永远不会被更新，`failure_summary` 被静默覆盖
+
+**F-07: EventRepository 路由前缀过滤器使用错误分隔符**
+- 过滤用 `.` 拼接，但存储用 `/` 分隔
+- 所有路由前缀查询返回零结果
+
+### 3.3 HIGH 发现
+
+**F-08: Recovery.scanOrphanReferences() 为桩** — FK-off 孤儿扫描未实现  
+**F-09: Recovery.checkPidLiveness() 为桩** — PID 存活检查未实现  
+**F-10: Workspace GC SQL 逻辑错误** — AND/OR 缺少括号，`session_id` 过滤被绕过  
+**F-11: EvidenceStore 使用内存 Map** — 重启后证据查询为空  
+**F-12: SessionManager.close_session() 不刷新 ui_state** — 违反退出时刷新不变量
+
+### 3.4 MEDIUM 发现
+
+**F-13:** `command.completed` 投影传递 `diagnostic_ids` 但 `command_runs` 表无此列  
+**F-14:** EventStore 单例用空 `DatabaseHandle` 初始化  
+**F-15/F-16:** 多个仓库在 insert 时硬编码 status，与 EventStore 传递值冲突
+
+---
+
+## 4. 安全模型审计 (packages/runtime/src/security/ vs security-model-v1.md)
+
+### 4.1 路径分类器 (CRITICAL 偏差)
+
+| 设计 PathRiskCategory | 实现 | 状态 |
+|---|---|---|
+| `project` | `project_source`, `project_config` | 拆分为二 |
+| `project_air_shared` | — | **缺失** |
+| `project_air_local` | — | **缺失** |
+| `credential_store` | — | **完全缺失** (`~/.ssh`, `~/.gnupg` 等均不检测) |
+| `unknown` | — | **缺失**; 默认为 `project_config` (过于宽松) |
+
+### 4.2 命令风险分析器 (CRITICAL 偏差)
+
+| 设计 CommandRisk | 实现 | 状态 |
+|---|---|---|
+| `build_or_test` | — | **缺失** |
+| `dependency_install` | — | **缺失** |
+| `privilege_escalation` | — | **缺失** |
+| `unknown` | — | **缺失** |
+
+**运行时 Bug:** `'sudo_likely' in trimmed` — `in` 操作符在字符串上检查 String 原型属性，永远为 `false`。
+
+### 4.3 权限引擎 (CRITICAL 偏差)
+
+| 设计要素 | 实现 | 状态 |
+|---|---|---|
+| 4 个 Profile (`low/normal/high/developer`) | 按 agent 类型的 profile | **完全不匹配** |
+| 6 个 Action (`allow/deny/ask_user/block/refuse/announce_then_run`) | 7 个 Action (3 个不同) | **缺失 `block/refuse/announce_then_run`** |
+| `PermissionGrantScope` (5 级) | **完全缺失** | 无授权范围追踪 |
+| `risk_level` 字段 | **缺失** | |
+| `backup_required` 字段 | **缺失** | 无写入前备份逻辑 |
+| 策略违规 `refuse` | **缺失** | 无拒绝检测 |
+
+**Cut line 合规: 0/10 项完全满足, 4 项部分满足, 6 项不满足。**
+
+### 4.4 SecretRedactor: 良好但有缺口
+
+14 个模式类别覆盖良好。缺失: `.env` 文件路径级检测、云凭证目录模式、`auth_ref` 引用系统、Provider 适配器集成。
+
+---
+
+## 5. 工具注册表审计 (ToolRegistry vs tool-registry-v1.md)
+
+### 5.1 MVP 工具缺失 (16/28 缺失)
+
+| 缺失工具 | 类别 |
+|---|---|
+| `fs.stat` | 文件系统 |
+| `process.kill` | 进程 |
+| `git.worktree.create` | Git |
+| `git.merge_workspace` | Git |
+| `project.scan` | 项目 |

+| `debug.parse_logs` | 调试 |
+| `gui.screenshot` | GUI 证据 |
+| `network.capture` | 网络证据 |
+
+### 5.2 多余工具 (10 个不在 MVP 索引中)
+
+`git.commit`, `git.branch`, `project.rules`, `project.context`, `artifact.read`, `context.compact`, `permission.check`, `permission.prompt`, `doctor.check`, `doctor.fix`
+
+### 5.3 工具 Schema 偏差 (主要工具)
+
+| 工具 | 设计字段 | 代码字段 | 偏差 |
+|---|---|---|---|
+| `fs.edit` | `old_string`, `new_string`, `expected_existing_sha256?` | `find`, `replace` | 字段名全部不同，缺安全校验和 |
+| `shell.run` | `cwd` (required), `timeout_ms?`, `stdin?`, `capture_mode?`, `purpose?` | `workdir` (optional), `timeout?`, `env?` | 名称/必需性/字段均不匹配 |
+| `artifact.create` | `type`, `original_name?`, `content?`, `source_path?`, `associated_entity_type?`, `associated_entity_id?`, `metadata?` | `name`, `type`, `content`, `metadata` | 缺 5 个字段 |
+| `context.assemble` | `purpose` (required enum), `refs?`, `token_budget?` | `max_tokens?` | 缺必需 `purpose` 枚举和 `refs` |
+
+### 5.4 ToolRegistry 运行时 Bug
+
+**CRITICAL:** `this.downgrade_to_readonly()` 和 `this.apply_sandbox_restrictions()` 在模块作用域 `ACTION_BRANCHES` 对象中被调用，`this` 不是 ToolRegistry 实例，运行时将抛出异常。
+
+---
+
+## 6. 能力系统审计 (CapabilityRegistry vs capability-trust-v1.md)
+
+### 6.1 Manifest Schema (CRITICAL 偏差)
+
+| 设计字段 | 实现 | 状态 |
+|---|---|---|
+| `capability_id` | `name` | 重命名 |
+| `display_name` | — | **缺失** |
+| `source` (CapabilitySource) | — | **完全缺失** |
+| `trust_level` (5 级) | `trust_level` (3 级) | **不匹配**: 设计 `built_in/project_local/user_installed/verified_publisher/untrusted` vs 代码 `core/trusted/untrusted` |
+| `publisher?` | — | **缺失** |
+| `events?` | — | **缺失** |
+| `config_schema?` | — | **缺失** |
+| `entrypoint?` | — | **缺失** |
+
+### 6.2 依赖模型
+
+设计: 富 `CapabilityDependency` 对象 (7 种 kind、检测器、安装器策略)。  
+实现: 简单 `string[]`。所有结构信息丢失。
+
+### 6.3 工具命名空间验证
+
+设计要求 `<capability-id>.<tool-name>` 命名空间，保留内置命名空间。`CapabilityManifestValidator` 无命名空间验证。
+
+---
+
+## 7. 调度器审计 (Scheduler vs scheduler-state-machine-v1.md)
+
+### 7.1 缺失状态 (CRITICAL)
+
+| 设计状态 | 实现 | 状态 |
+|---|---|---|
+| `BLOCKED` | — | **缺失** |
+| `CANCELLED` | — | **缺失** |
+| `TERMINATED` | — | **多余** (非设计规范) |
+
+### 7.2 Scheduler 接口不匹配
+
+| 设计方法 | 实现 | 状态 |
+|---|---|---|
+| `create_tasks(session_id, specs: TaskSpec[])` | `create_tasks({id,type,title,depends_on}[])` | 签名不匹配，缺 `session_id` |
+| `add_dependency(session_id, task_id, dep)` | — | **完全缺失** |
+| `load_graph(session_id)` | — | **完全缺失** |
+| `run_until_idle(session_id): SchedulerRunResult` | `run_until_idle(): SchedulerState` | 返回值类型不匹配 |
+| `cancel_task(task_id, reason)` | — | **完全缺失** |
+
+### 7.3 状态逻辑空洞
+
+| 状态 | 设计要求 | 实现 |
+|---|---|---|
+| DISPATCHING | 4 个动作 (workspace, events, control message, attempt) | 仅标记 running |
+| COLLECTING_RESULTS | 5 个动作 (validate, persist, terminal, classify, unblock) | 直通到 MERGING |
+| MERGING | 策略选择 (main/worktree/isolated_copy) | 直通到 REVIEWING_WAVE |
+| REVIEWING_WAVE | 调度 review 任务 | 直通到 REPAIRING_OR_CONTINUING |
+
+### 7.4 TaskGraph 偏差
+
+- 缺失 `serialization` 依赖类型 (4 种中缺 1 种)
+- `soft` 依赖对调度无任何影响
+- 冲突依赖不阻止同波次并发
+- TaskNode 缺少 `spec`, `assigned_agent_id`, `retry_count`, `workspace_id`
+
+### 7.5 WavePlanner 偏差
+
+- 所有任务分配到 `'default'` write area — write-area 串行化无效
+- `wave_id` 为 `number` (Date.now()) 而非设计要求的 `string`
+- 无 `workspace_assignments`, `model_assignments`, `reason` 字段
+- 8 条波次规划规则中仅 1 条部分实现
+
+### 7.6 RetryPlanner: 死代码
+
+逻辑正确 (重复失败签名升级)，但从未被 Scheduler 调用。
+
+---
+
+## 8. IPC 协议审计 (WorkerProtocol vs interface-contracts-v1.md §10)
+
+### 8.1 缺失 IPC 类型
+
+| 设计 IpcKind | 实现 | 状态 |
+|---|---|---|
+| `control` | — | **缺失** (个别控制消息存在但无 `control` 信封) |
+| `log` | — | **完全缺失** |
+| `tool.stream` | — | **完全缺失** |
+| `protocol.error` | — | **缺失** (用非标准 `worker.error` 替代) |
+
+### 8.2 信封形状不匹配
+
+设计 `IpcEnvelope` 有 9 个字段: `id, direction, kind, timestamp, session_id, agent_id, correlation_id?, protocol_version, payload`  
+实现 `WorkerMessage` 有 5 个字段: `id, type, direction, timestamp, payload`  
+**缺失:** `kind`, `session_id`, `agent_id`, `correlation_id`, `protocol_version`
+
+### 8.3 握手顺序反转
+
+设计: 父进程先发 `agent.start`，worker 回 `worker.ready`  
+实现: worker 先发 `worker.ready`，父进程后发 `agent.start` — **顺序相反**
+
+---
+
+## 9. 主代理状态机审计 (MainAgent vs main-agent-state-machine.md)
+
+### 9.1 缺失状态 (7/13)
+
+| 设计状态 | 实现 | 状态 |
+|---|---|---|
+| `CLASSIFYING` | — | **缺失** |
+| `SCHEDULING` | — | **缺失** |
+| `ARCHITECTURE_DESIGNING` | — | **缺失** |
+| `CONFIRMING` | — | **缺失** (用 `AWAITING_CONFIRMATION` 替代，语义不同) |
+| `EXECUTING` | — | **缺失** |
+| `INTERRUPTING` | — | **缺失** |
+| `ARCHITECTURE_REVISING` | — | **缺失** |
+
+### 9.2 其他偏差
+
+- 分类用正则而非 LLM
+- Direct Mode `/direct`/`/done` 不完整
+- SUMMARIZING 不触发 ExperienceMiner
+- 无 `requirement.changed` 处理
+
+---
+
+## 10. Worker 角色审计 (packages/workers/ vs 设计)
+
+### 10.1 结果形状不匹配
+
+所有 5 个角色均返回局部结果类型而非设计要求的 `WorkerResult<T>` 信封:
+
+| 角色 | 设计要求 | 实际返回 |
+|---|---|---|
+| Executor | `WorkerResult<ExecutorResult>` (12 字段) | `{status, changes?, verification?, error?}` (4 字段) |
+| Reviewer | `WorkerResult<ReviewerResult>` + `verdict` 枚举 | `{status, findings[], summary}` |
+| Debugger | `WorkerResult<DebuggerResult>` + `BlockerReport?` | `{status, root_cause, fix_applied?, evidence_refs}` |
+| Compactor | `WorkerResult<CompactorResult>` + `summary_id` | `{status, summary_content, tokens_freed}` |
+| ExperienceMiner | `WorkerResult<ExperienceMinerResult>` + `MemoryCandidate[]` | `{status, entries[], summary}` |
+
+### 10.2 执行纪律缺失
+
+- read-before-edit 未强制
+- 完成门禁 (verification pass or explicit skip) 未强制
+- DebuggerRole 不查 DebugKnowledgeStore
+- ExperienceMiner 触发路径未接入 Scheduler
+
+---
+
+## 11. LLM Provider 层审计 (packages/llm/ vs provider-capability-matrix-v1.md)
+
+### 11.1 能力矩阵覆盖度: ~20%
+
+缺失:
+- `quality_tier`, `cost_tier` 字段未在矩阵中使用
+- 17 个 `supports` 字段中仅 5 个实现
+- 整个 `conversion` 块、`limits` 块、`default_use` 块缺失
+- `ProviderKind` 分类未使用
+- Fallback 策略、调度器分配模式缺失
+
+### 11.2 Provider 配置安全
+
+代码直接存储 `api_key` 原始值，设计要求 `auth_ref` 间接引用，密钥永不进入 session DB/events/artifacts。
+
+### 11.3 LLM 包未引用 contracts
+
+`packages/llm` 在本地定义所有类型而非从 `packages/contracts` 导入，违反了基线 §4 依赖方向规则。
+
+---
+
+## 12. 上下文装配审计 (ContextAssembler vs prompt-layering-v1.md)
+
+### 12.1 层级缺失 (4/10)
+
+| 层 | 设计 | 实现 | 状态 |
+|---|---|---|---|
+| L0 System | 系统身份 | 硬编码字符串 | PARTIAL |
+| L1 Capability | 能力声明 | 存在 | PASS |
+| L2 Safety | 安全规则 | 硬编码 | PARTIAL |
+| L3 Project Rules | 项目规则 | 存在但路径错误 | PARTIAL |
+| L4 Architecture | 架构上下文 | 存在 | PASS |
+| L5 Plan/Task | 计划/任务 | 存在 | PASS |
+| L6 Evidence | 证据上下文 | — | **缺失** (TODO) |
+| L7 Conversation | 对话历史 | — | **缺失** (TODO) |
+| L8 Tool Output | 工具输出 | — | **缺失** (TODO) |
+| L9 Immediate | 即时指令 | — | **缺失** (TODO) |
+
+### 12.2 输出格式
+
+设计要求输出 Anthropic canonical messages。实现输出自定义 `PromptLayer[]` 结构，未转换为 canonical 格式。
+
+### 12.3 冲突检测: 缺失
+
+设计要求层间冲突报告 (如安全规则与项目规则矛盾)。实现无任何冲突检测。
+
+### 12.4 CompactionPolicy: 无 copy-on-write
+
+设计要求 copy-on-write 压缩，保留回溯引用。实现仅有阈值检查，无工件持久化，无回溯保留。
+
+---
+
+## 13. TUI/HUD 审计 (packages/tui/ vs 设计)
+
+### 13.1 组件覆盖: 完整
+
+9 个视图组件全部存在: SessionView, TaskListView, AgentStatusView, ToolRunView, DiffView, PermissionPrompt, BlockerReport, HudView + TuiApp。
+
+### 13.2 缺口
+
+- 无 OpenTUI renderer 集成 (组件定义但无渲染引擎)
+- 无对话消息渲染表面
+- PermissionPrompt/BlockerReport 无路由连接
+- ProjectionStore.rebuild() 为桩 — 仅处理 5 种事件类型
+- HUD 预设 (Full/Essential/Minimal) 未实现
+
+---
+
+## 14. C++ 工具链审计 (packages/toolchain-cpp/ vs FR-017)
+
+### 14.1 组件存在但断连
+
+- `CppProjectDetector`, `CppBuilder`, `CMakeConfigurator`, `CppTestRunner`, `DiagnosticParser`, `ClangdClient`, `CppcheckRunner` 均存在
+- `CppToolRegistrar` 注册了工具定义但 **未注册到 ToolRegistry** (与 FR-010 的 16 个缺失工具一致)
+- `ClangdClient` 方法全部为桩
+- 源文件发现返回空数组
+
+### 14.2 安全风险
+
+`CppBuilder.build()` 和 `CppTestRunner.run()` 使用 `execSync` 字符串拼接，存在命令注入风险。
+
+---
+
+## 15. CLI 命令审计 (packages/cli/ vs 设计)
+
+### 15.1 命令覆盖: 完整 (PASS)
+
+所有 11 个必需命令存在: `init`, `run`, `doctor`, `provider`, `resume`, `compact`, `history`, `session`, `restore`, `e2e`, `release`。
+
+### 15.2 init 命令偏差
+
+- 不创建 17 个规范 `.air/` 子目录
+- 直接写文件系统，绕过 ToolRegistry/PermissionEngine (违反 INV-3)
+
+### 15.3 额外包
+
+代码中存在 `packages/workers/` 包，不在基线 §4 的规范包列表中。这是一个合理的分离 (worker 入口点独立于 runtime)，但需要 ADR 记录。
+
+---
+
+## 16. 运行时语义合规审计 (vs runtime-semantics-v1.md)
+
+| 不变量 | 合规 | 说明 |
+|---|---|---|
+| INV-1: 持久事件+域表同事务 | FAIL | F-04: EventStore.project() 不传事务 |
+| INV-2: EventIngestor 不创建调度任务 | PASS | |
+| INV-3: 副作用经 ToolRegistry/PermissionEngine | FAIL | init 直接写 FS |
+| INV-4: EventBus handler 错误不中断订阅 | PASS | |
+| INV-5: 临时事件合并 | PASS | 5 秒窗口正确 |
+| INV-6: 工件 temp-rename 原子写 | PASS | |
+| INV-7: Workspace GC 策略 | PARTIAL | GC 逻辑正确但 SQL 有 bug (F-10) |
+| INV-8: Agent heartbeat 持久化 | FAIL | 仅内存，不写 DB |
+| INV-9: ExperienceMiner 4 种触发路径 | FAIL | 0 种实现 |
+| INV-10: read-before-edit 强制 | FAIL | 未实现 |
+| INV-11: 完成门禁强制 | FAIL | 未实现 |
+
+---
+
+## 17. 正面发现 (代码与设计匹配的部分)

+2. **SQLite Schema 完整:** 17 表、38 索引、PRAGMA、schema_meta 完全匹配
+3. **事件注册表完整:** 54 个持久事件 + 7 个临时事件全部注册
+4. **Enum 验证完整:** 18 个闭枚举全部覆盖
+5. **ArtifactStore 原子写入正确:** temp → sha256 → rename → event 流程完整
+6. **EventBus 错误隔离正确:** handler 异常不中断订阅
+7. **临时事件合并正确:** 7 种临时事件类型全部识别，5 秒窗口
+8. **EventIngestor 分离正确:** 持久/临时路径分离，不创建调度任务
+9. **SecretRedactor 覆盖良好:** 14 种凭证模式
+10. **CLI 命令完整:** 11/11 必需命令
+11. **WorkspaceManager GC 保留策略正确:** merged 7 天, abandoned 3 天
+12. **Heartbeat 合并窗口正确:** 5 秒
+13. **RetryPlanner 失败签名升级逻辑正确:** (但未接入)
+14. **所有 16 个仓库 CRUD 操作完整:** get/insert/update + 领域查询方法
+
+---
+
+## 18. 修复优先级建议
+
+### P0 (立即修复 — 阻塞核心不变量)
+
+1. **F-04: EventStore 事务边界** — 将 `_tx` 传递给所有仓库方法
+2. **F-05: Workspace status 枚举值** — `'created'` → `'active'`, `'merging'` → metadata
+3. **F-06: TaskAttemptRepository 列映射** — `failure_summary` → `failure_signature`
+4. **F-07: EventRepository 路由分隔符** — `.` → `/`
+5. **ToolRegistry `this` 绑定 bug** — 重构 ACTION_BRANCHES 为方法调用
+6. **CommandRiskAnalyzer `in` 操作符 bug** — `'sudo_likely' in trimmed` → `trimmed.includes('sudo')`
+
+### P1 (短期修复 — 功能性缺陷)
+
+7. **F-01/F-02: 项目级 DB schema** — 对齐 DebugKnowledgeStore 和 LearnedMemoryStore
+8. **补全 15 个缺失契约接口** — EventBus/EventStore/EventIngestor/ContextAssembler 等
+9. **PathClassifier 类别对齐** — 添加 `credential_store`, `project_air_shared/local`, `unknown`
+10. **PermissionEngine 类型对齐** — 4 profile, 6 action, grant scope
+11. **Scheduler 状态机补全** — BLOCKED/CANCELLED 状态, cancel_task, load_graph
+12. **IPC 信封补全** — 添加 5 个缺失字段, 修正握手顺序
+13. **注册 16 个缺失 MVP 工具** — fs.stat, process.kill, cpp.*, debug.*, gui.*, network.*
+14. **Main Agent 状态机补全** — 7 个缺失状态
+
+### P2 (中期修复 — 完整性)
+
+15. **ContextAssembler L6-L9** — 补全 4 个缺失层
+16. **Provider 能力矩阵** — 补全 ~80% 缺失字段
+17. **Worker 结果形状对齐** — 统一为 `WorkerResult<T>` 信封
+18. **Capability manifest 对齐** — 5 级 trust, 富依赖模型, 命名空间验证
+19. **Recovery 实现** — 孤儿扫描、PID 存活检查
+20. **EvidenceStore 持久化** — 从 EvidenceRepository 查询而非内存 Map
+
+### P3 (长期 — 质量与文档)
+
+21. **ADR 记录** — workers 包、Provider 类型强化、Doctor 扩展等设计偏差
+22. **DoctorIssueSeverity** — 添加缺失的 `"error"` 值
+23. **工具 Schema 对齐** — fs.edit, shell.run, artifact.create 等字段名/类型
+24. **Scope Escalation 实现** — ScopeImpactLevel, BlockerReport 集成
+25. **TUI renderer 集成** — OpenTUI/Solid 渲染引擎接入
+

+
+## 20. 结论
+
+当前 V1.0.0 Alpha 代码实现处于 **骨架基本就位、语义大面积偏差** 的状态。monorepo 结构、SQLite schema、事件注册表等基础设施质量较高，但核心运行时子系统（Scheduler、IPC、Security、Context）与冻结基线之间存在结构性分歧。
+
+**最高风险项** 是 EventStore 事务边界违反 (F-04)，它会导致每个持久事件的域表更新在事务外执行，破坏数据一致性不变量。其次是 workspace status 枚举错误 (F-05) 会导致首次 workspace 创建即崩溃。
+
+建议在继续 Phase 2-8 实现之前，先完成 P0 和 P1 修复，确保核心不变量和接口契约与设计文档对齐。

+## 0. 综合结论（四模型共识）
+
+### 0.1 一致裁决
+
+> **四个独立审计模型在以下核心判断上完全一致**：
+> AirCoding V1.0.0 Alpha 当前处于 **「架构骨架与基础设施质量高，但核心运行时子系统语义大面积偏离冻结基线」** 的状态。
+> **不应在当前状态下发布**；必须先关闭阻断级缺陷。
+
+| 维度 | 四模型一致结论 |
+|------|--------------|
+| **基础设施层** | ✅ Monorepo / SQLite Schema / 事件注册表 / Enum 验证 / 依赖方向 — 质量高 |
+| **契约层** | ⚠️ contracts 编码良好，但下游系统性重定义本地类型、不 import 契约（Opus + Qwen 明确，DeepSeek + M3 印证） |
+| **执行链路** | ❌ Scheduler / IPC / Security / Context / TUI / outbox — 语义偏离或链路断裂 |
+| **安全** | ❌ 3 处命令注入 + 权限旁路 + 弱加密密钥（四模型均独立发现命令注入） |
+| **可发布性** | ❌ 四模型均判定不可发布 |
+
+### 0.2 评级谱系
+
+```
+DeepSeek  B+  ████████░░  (乐观：文件齐全=骨架完整)
+Opus 4.8  C+  █████░░░░░  (严格：逐字段不符规范)
+MiniMax   C+  █████░░░░░  (务实：接口在但链路断)
+Qwen3.7   D+  ████░░░░░░  (最严：规范一致性平均<45%)
+─────────────────────────
+综合评级  C   █████░░░░░  (骨架B级 / 执行链路D级)
+```
+
+**评级分歧根源**：DeepSeek 以"实现计划任务完成度"（123/123 文件创建）为主轴 → B+；其余三模型以"与冻结规范的语义一致性"为主轴 → C+/D+。**Meta 裁决采纳后者**：文件存在 ≠ 语义正确，综合评级 **C（骨架 B / 执行 D）**。

+## 7. Meta-Audit 方法论说明
+
+### 7.1 交叉验证原则
+- **置信度分级**：≥3 模型确认 = 高置信🔴；2 模型 = 中置信；1 模型 = 需复核
+- **冲突解决**：评级分歧时，采纳「语义一致性」视角（3 模型）而非「文件完成度」视角（1 模型）
+- **独有发现保留**：单模型独有项不丢弃，标注「需复核」纳入路线图
+
+### 7.2 四模型互补性
+```
+DeepSeek (广度·计数) ──┐
+Opus     (深度·字段) ──┤
+                       ├──→ Meta-Audit (交叉确认 + 优先级融合)
+MiniMax  (链路·治理) ──┤
+Qwen     (覆盖·百分比)─┘
+```
+- 四模型从**完全不同的角度**独立审查，关键缺陷（命令注入 B8、DB schema B3、MainAgent B13、TUI B15）获**4/4 满票确认**，置信度极高
+- 评级从 B+ 到 D+ 的分布反映了「完成度 vs 一致性」的根本张力，Meta 裁决取 **C（骨架 B / 执行 D）**
+
+### 7.3 综合数据
+| 指标 | 数值 |
+|------|------|
+| 四模型发现总数（去重前） | 97 + 140 + 38 + 84 ≈ 359 |
+| 高置信阻断项（≥3模型） | 15 项 |
+| 中置信阻断项（2模型） | 7 项 |
+| INV 合规 | PASS 2 / 部分 3 / FAIL 6 |
+| 加权规范一致性 | ≈ 52% |
+| 正面共识项 | 14 项 |
+
+---
+
+## 8. 最终裁决
+
+> **综合评级：C（骨架 B 级 · 执行链路 D 级）**
+>
+> **可发布性：否**。四个独立审计模型一致判定 V1.0.0 Alpha 不应在当前状态发布。
+>
+> **核心判断**：
+> 1. **基础设施扎实**——Monorepo、SQLite Schema、事件注册表、依赖方向四模型满票通过，这是真实的工程资产。
+> 2. **契约系统性漂移**——contracts 忠实编码规范，但 runtime/llm/workers/tui/toolchain-cpp 系统性重定义本地冲突类型、几乎不 import 契约（Opus 揭示根因，Qwen 量化为 15 契约缺失）。
+> 3. **核心链路断裂**——Scheduler 空壳、TUI 无渲染、IPC 握手反转、outbox 不发事件，使「一个任务从派发到完成」的主路径无法真正贯通（M3 揭示）。
+> 4. **三大不变量失守**——INV-1/2/3 四模型独立判 FAIL，是评级压到 C 的决定性依据。
+> 5. **安全红线**——3 处命令注入（4/4 满票）+ 权限旁路 + 弱密钥，任一项都是 GA 阻断。
+>
+> **建议**：冻结新特性，按统一路线图阶段 A（安全红线）→ B（链路连通）→ C（规范对齐）→ D（完整性）顺序整改。阶段 A 必须 100% 关闭方可考虑下一里程碑。
