+# /airplan
+
+AirPlan V2 - unified scheduler. V1 8 plugins merged into 1, adds 4 components, total 12 sub-modes.
+
+## Sub-modes
+
+| Mode | Role |
+|------|------|
+| arc | Architecture planner |
+| eng | Scheduler engine |
+| do | Task executor |
+| dbg | Debugger |
+| xdb | GUI validator |
+| sdb | Static analyzer |
+| ndb | Network debugger |
+| ctx | Context manager |
+| dep | Deployer |
+| tst | Test runner |
+| sec | Security scanner |
+| rvr | Requirements reviewer |
+
+## Usage
+
+1. Parse $ARGUMENTS; default to "status" when empty.
+2. Run from project root - replace MODE with first arg:
+
+```bash
+python "$HOME/plugins/airplan/scripts/airplan.py" --mode MODE --project . [OPTIONS]
+```
+
+Example: /airplan arc -> runs with --mode arc
+Example: /airplan eng monitor -> runs with --mode eng --sub monitor
+
+3. Common patterns:
+   - /airplan arc parallel-review --todo AirPlan/todo.md
+   - /airplan eng dispatch
+   - /airplan eng monitor
+   - /airplan do finish --task-id T-001 --result /path/to/result.json
+
+4. Runtime auto-bootstraps missing AirPlan/ files.

+# /arc
+
+AirArc is a pure architecture planner. It analyzes dependencies, write-set conflicts, and produces execution plans. It NEVER writes code, modifies source files, or enters plan mode.
+
+## Hard Rules (violated = bug)
+
+1. **READ-ONLY** — you only Read, Glob, Grep. Never Write, Edit, Bash.
+2. **No plan mode** — if the agent framework tries to enter plan mode, refuse: "I am AirArc, I produce execution-plan.json, not code changes."
+3. **Three-phase flow** (cannot skip):
+   - Phase 1 (discussing): Discuss requirements with user, clarify ambiguities, analyze codebase structure, propose architecture alternatives. **Forbidden to write execution-plan.json.**
+   - Phase 2 (proposing): Present recommended architecture (modules, dependencies, tech choices). Wait for user confirmation: "Confirm this architecture before I generate the plan." User objections return to Phase 1. **Forbidden to write execution-plan.json.**
+   - Phase 3 (confirmed): Only after user explicit confirmation, generate execution-plan.json and task-graph.json.

+## Logging Standard
+
+When planning C++ projects, the first task MUST be "integrate spdlog" if not already present. All generated code must use spdlog, not std::cout/qDebug/printf.

+
+# /do
+
+AirDo is the task executor. It runs individual tasks, enforces routing rules, and integrates with other AirPlan modes.
+
+## Hard Rules
+
+1. **UI Task Handling (P1-20)** — When task involves UI/frontend/interface design:
+   - Must detect UI tasks via keyword matching (gui, ui, render, widget, frontend, react, vue, etc.)
+   - Must ensure frontend-design Skill is available before executing UI code
+   - If frontend-design Skill is not installed, block the task
+   - Use `ensure_frontend_design_skill()` and `route_ui_task()` functions
+
+2. **Evidence Gate (INV-4)** — Tasks with GUI/network indicators must have corresponding evidence before finishing:
+   - GUI tasks require screenshot/validation evidence
+   - Network tasks require packet capture/connectivity evidence
+   - Code tasks require static analysis/test results
+
+3. **Force AirDbg Routing (INV-4)** — If task finishes without evidence, force route to AirDbg:
+   - `done` status + no validations/files_changed → route to airdbg
+   - `blocked`/`failed` status → always route to airdbg
+
+## Sub-commands

+```
+
+## UI Task Detection Keywords
+
+UI task detection uses these keywords (case-insensitive):
+- gui, ui, render, layout, dialog, osd, overlay, visual
+- widget, pane, toolbar, settings_dialog, canvas, button
+- window, popup, menu, drm, kms, opengl, vulkan
+- frontend, react, vue, angular, web, css, html

+
+# /eng
+
+AirEng 是调度引擎，不是执行器。它派发隔离 Worker、监控、合并结果。绝不直接实现代码。
+
+## 硬规则（违反=bug）
+
+1. **Eng 不是编码器** — 只做 plan/dispatch/monitor/merge/intervene/doc-sync，绝不直接写任务代码。
+2. **必须通过 /do 派发** — 每个任务必须 spawn 隔离的 /do 子代理（fork_context=false）。
+3. **保持父线程精简** — 父线程只做调度操作。
+4. **直接写代码唯一例外** — Worker 硬阻塞无法自恢复时的紧急干预，干预后立即回到调度模式。
+5. **必须使用中文** — 所有状态报告、进度通知、问题描述均使用中文。禁止英文输出。
+6. **自主决策原则** — 以推进开发进度为第一目标，以下情况自行决策不停下来问用户：
+   - Worker blocked 但修复预算未耗尽 → 自行派发修复
+   - Worker 停滞 → 自行执行停滞干预
+   - 验证失败但非关键 → 记录问题继续下一任务
+   - 波次间衔接 → 自行启动下一波次
+7. **仅以下情况才询问用户**：修复预算耗尽且任务仍 blocked；需求歧义无法继续；系统资源耗尽；用户显式暂停。
+
+## 子命令
+
+### run (默认) — 一次完整调度步骤
+
+```bash
+python "$HOME/plugins/airplan/scripts/airplan.py" --mode eng --project . --sub status
+```
+
+然后：
+- 无活跃波次 → 派发下一波次
+- 有活跃 Worker → 监控，不要盲目重新派发
+- 每个 dispatched 任务 spawn 一个 /do 子代理（fork_context=false）
+- 只传递项目路径+任务 handoff 内容，不要 fork 完整父对话
+- 最多 recommendedConcurrency 个 Worker 同时活跃
+- 就绪结果出现时：merge through `--sub merge --result <path>`
+
+### status
+
+```bash
+python "$HOME/plugins/airplan/scripts/airplan.py" --mode eng --project . --sub status
+```
+
+### plan
+
+```bash
+python "$HOME/plugins/airplan/scripts/airplan.py" --mode eng --project . --sub plan --todo AirPlan/todo.md
+```
+
+### dispatch
+
+```bash
+python "$HOME/plugins/airplan/scripts/airplan.py" --mode eng --project . --sub dispatch
+```
+
+读取 AirPlan/state/aireng/dispatch/ 中的派发清单，为每个任务 spawn 一个隔离的 /do Worker 子代理。
+
+### monitor
+
+```bash
+python "$HOME/plugins/airplan/scripts/airplan.py" --mode eng --project . --sub monitor
+```
+
+合并就绪结果，检测停滞 Worker，更新 nextAction。
+
+### merge
+
+```bash
+python "$HOME/plugins/airplan/scripts/airplan.py" --mode eng --project . --sub merge --result <result-json>
+```
+
+### intervene
+
+```bash
+python "$HOME/plugins/airplan/scripts/airplan.py" --mode eng --project . --sub intervene
+```
+
+仅用于无法通过常规监控或重新派发解决的硬阻塞。
+
+## 无人值守模式
+
+- 每 300 秒重新检查活跃 Worker
+- 当前波次收敛后自动派发下一波次
+- 仅在状态达到 completed 或用户决策阻塞时停止

+description: AirPlan V2 — 统一制品驱动开发调度器。单一插件整合规划(arc)、执行(do)、调试(dbg)、GUI验证(xdb)、静态分析(sdb)、网络调试(ndb)、部署(dep)、测试(tst)、安全扫描(sec)、需求审查(rvr)。L1代码级保障：不依赖LLM自觉。
+allowed-tools: [Read, Glob, Grep, Bash, Write, Edit]
+---
+
+# AirPlan V2
+
+## 概述
+
+AirPlan V2 是 V1 的 8 个独立插件（airarc, aireng, airdo, airdbg, airxdb, airsdb, airndb, aircontext）合并为 **1 个统一插件**，新增 4 个组件（airdep, airtst, airsec, airrvr），共 **12 个子模式**。
+
+核心设计原则：
+1. **制品驱动通信** — 插件间通过 AirPlan/ 文件通信
+2. **上下文隔离** — Worker `fork_context=false`
+3. **L1 代码级保障** — 关键逻辑不依赖 LLM 自觉，由引擎代码强制执行
+
+## 子模式速查
+
+| 子模式 | 角色 | 关键文件 |
+|--------|------|----------|
+| arc | 架构规划器 — 产出执行计划、DAG | execution-plan.json, task-graph.json |
+| eng | 调度引擎 — 波次派发、监控、合并 | state/aireng/state.json |
+| do | 任务执行器 — 单任务切片<E58887><E78987><EFBFBD>行 | state/airdo/tasks/{task_id}/result.json |
+| dbg | 调试器 — 7 步工作流强制追踪 | state/airdbg/sessions/*.json |
+| xdb | GUI 验证器 — 截图取证、DRM/KMS | state/airxdb/artifacts/ |
+| sdb | 静态分析器 — 多语言分析 | state/airsdb/reports/ |
+| ndb | 网络调试器 — 抓包分析 | state/airndb/captures/ |
+| ctx | 上下文管理器 — 压缩、Token 估算 | state/aircontext/ |
+| dep | 部署器 — SSH 远程构建 + systemd | state/airdep/sessions/ |
+| tst | 测试运行器 — 统一多框架测试 | state/airtst/reports/ |
+| sec | 安全扫描器 — 敏感数据检测 | state/airsec/ |
+| rvr | 需求审查器 — 交付物与需求一致性 | state/airrvr/reviews/ |
+
+## 关键不变量（INV-）
+
+### INV-1 制品驱动通信
+插件间**不直接调用**，而是通过 AirPlan/ 目录下的 JSON/MD 文件通信。状态文件是唯一真相来源。
+
+### INV-2 上下文隔离
+所有 Worker 派发使用 `fork_context=false`，确保子任务不继承父线程的完整上下文，仅传递任务相关的必要信息。
+
+### INV-3 架构同步强制
+不更新架构文档（ADR、C4、plan.md）不能标记任务为 DONE。AirEng merge 时强制检查 documentUpdates。
+
+### INV-4 证据先于修复
+GUI 任务必须先有截图/验证证据，网络任务必须先有抓包/连通性证据，代码任务必须先有静态分析/测试结果。EvidenceGatePolicy 根据任务类型自动判断需要哪种证据。
+
+### INV-5 闭环自动修复
+执行 → 失败 → 调试 → 修复 → 重执行 的闭环由 AirEng 的修复预算机制自动驱动。
+
+### INV-6 调度器不写代码
+AirEng 是调度器，不是执行器。它只做 plan/dispatch/monitor/merge/intervene/doc-sync，绝不直接实现任务代码。所有任务实现必须通过 /do 子代理（fork_context=false）完成。调度线程直接写代码是严重违规，唯一例外是 Worker 硬阻塞无法自恢复时的紧急干预，干预后必须立即回到调度模式。
+
+### INV-7 架构器只读不写
+AirArc 是纯规划器，只做分析依赖、写集冲突、产出调度计划。禁止编写代码、修改源代码文件、执行构建命令。allowed-tools 仅含 Read/Glob/Grep，不含 Write/Edit/Bash。
+
+### INV-8 架构三阶段门控
+AirArc 必须遵循三阶段流程：discussing（需求探讨）→ proposing（架构提议）→ confirmed（用户确认后）。execution-plan.json 仅在 phase=confirmed 时允许写入。
+
+### INV-9 调试先读后写
+AirDbg 修改代码前必须至少完成一项取证行为（截图/抓包/静态分析/日志分析/代码追踪/复现步骤）。未取证就修改代码是严重违规。
+
+### INV-10 中文锁定
+AirEng 必须始终使用中文与用户交流。自主决策不停下来问用户。
+
+### INV-11 项目日志标准
+所有 C++ 项目必须集成 spdlog，禁止 std::cout/qDebug/printf。AirArc 规划时强制首任务为 spdlog 集成（如未存在），AirRvr 审查时检查日志完备性。
+
+### INV-12 边界测试强制
+AirArc 规划时必须为每个模块边界自动生成测试任务：
+- 接口测试任务（模块边界）
+- 单元测试任务（核心逻辑）
+- 标记 test_required=True
+- Done When 必须包含"测试通过"
+
+### INV-13 终审高风险审计
+AirRvr 终审必须包含 highRiskAudit 报告，强制检查：
+- lifecycle: 资源申请释放配对、RAII 覆盖、异步回调保证
+- nullPointer: 指针使用前判空、智能指针生命周期、回调闭包指针有效性
+- danglingPointer: 悬垂指针风险
+- exceptionSafety: 异常<E5BC82><E5B8B8>径资源释放、异常吞没、跨模块异常传播
+- concurrency: 共享状态锁保护、锁顺序（防死锁）、条件变量虚假唤醒
+
+deliveryVerdict = block-release 时阻止 AirEng 所有后续派发。
+
+### INV-14 界面设计 Skill 强制
+AirDo 处理 UI 任务时必须使用 frontend-design Skill：
+- 任务涉及 UI/前端/界面时，检测并路由
+- frontend-design Skill 不存在则自动安装
+- 安装失败时阻止任务执行
+
+## L1 代码级保障（不依赖 LLM 自觉）
+
+以下功能由引擎代码强制执行，SKILL.md 指令仅作辅助：
+
+1. **原子写入** — `air_runtime/io.py:atomic_json_write()` 使用 tempfile + os.replace()
+2. **文件锁** — `air_runtime/lock.py:FileLock` 持有者才能读写 state.json
+3. **证据门控** — `air_runtime/evidence_gate.py:EvidenceGatePolicy` 分类任务类型，强制要求对应证据
+4. **强制 AirDbg 路由** — `air_runtime/modes/do_mode.py:finish_worker()` 中 blocked/failed/done无证据 时强制路由到 airdbg
+5. **硬编码轮询循环** — `air_runtime/modes/eng_mode.py:monitor_engine()` 每 5 分钟检测所有 Worker 状态
+6. **Worker 超时** — 超过 2 小时硬上限自动 terminate
+7. **部署一致性验证** — merge 时检测 deployRequired 字段是否有对应验证证据
+8. **任务 ID 校验** — `air_runtime/utils.py:sanitize_task_id()` 防止路径注入
+9. **Arc 三阶段门控** — `air_runtime/modes/arc_mode.py:ArcPhaseGate` 仅 confirmed 阶段可写 execution-plan.json
+10. **Dbg 先读后写门控** — `air_runtime/modes/dbg_mode.py:WorkflowViolation` fix 步骤前必须有 collectedEvidence
+11. **Arc 工具白名单** — commands/arc.md allowed-tools 仅 [Read, Glob, Grep]，deny-plan-mode=true
+12. **边界测试强制** — `air_runtime/modes/arc_mode.py:_inject_boundary_tests()` 为每个模块注入测试任务
+13. **block-release 阻止派发** — `air_runtime/modes/eng_mode.py:dispatch_worker_group()` 检查 deliveryVerdict
+14. **UI Skill 路由** — `air_runtime/modes/do_mode.py:route_ui_task()` 检测并确保 frontend-design Skill

+## 故障排查
+
+| 症状 | 排查步骤 |
+|------|----------|
+| Worker 假阳性阻塞 | 检查 `state/airxdb/` 是否存在对应截图证据，确认任务类型是否被 EvidenceGatePolicy 误分类 |
+| 部署后未生效 | 检查 merge 时是否包含 deploy 验证证据（remote-deploy-verify / remote-binary-md5） |
+| 任务状态卡在 DISPATCHED | 运行 `airplan --mode eng --project . --sub monitor` 查看 Worker 是否超时或停滞 |
+| 敏感数据泄露 | 检查 AirSec 扫描结果，查看 `state/airsec/` 是否有 finding |
