/**
 * R 段：团队式编排引擎（第五轮 H1-H5）确定性测试。
 * 全部离线可复现（不依赖外网/托管目录状态）：
 *  - R1 catalog 模板与畸形 spec 校验、安装源可信度
 *  - R2 installer 托管布局/探活/幂等（用 GW_AGENT_HOME 临时根 + 假 bin，不触网）
 *  - R3 pool 发现/ensureAgent/成本熔断
 *  - R4 凭据隔离（argv 无 key、子进程 env 剥离、配置文件无 key）
 *  - R5 编排 prompt 注入检测 + REAL 无 key 硬失败（子进程，干净环境）
 *  - R6 schema 校验失败自动重试（注入脚本化 llm，确定性）
 *  - R7 离线端到端：fixture 外部 CLI 进程 + native + 离线 writer，审查读文件、返工、成品与证据契约
 *  - R8 版本 5.0.0 / scripts / bin 齐备
 *  - R9 附录 A 双 key：退避重试/自动切 A/双失败 fatal 如实上报/子进程 env 切换（fetch 打桩，确定性）
 *  - R10 R6 codex 通道统一 xxcsn/responses/CODEX_API_KEY（配置渲染/env 导出/探活打桩）
 *  - R11 双 key 双失败统一 all-keys-failed（401 场景 + chatJSON 不空转）
 *  - R12 H4 证据链：会话记录/实时状态/artifacts.json/权威清单审计/评审摘要（离线 e2e）
 *  - R13 H4 amend 中途改任务 + watchdog 故障注入自动重试（离线 e2e，确定性）
