+## DEV 测试授权分级
+
+`DEV` 只说明目标环境，不自动说明允许的写入级别。所有 runner prompt 和 supervisor closeout 都必须把 DEV 验证分成 `read-only`、`live-read` 和 `live-mutating` 三类；如果 prompt 没有显式分类，默认按 `read-only` 处理。
+
+| 分级 | 含义 | 常见允许动作 | 禁止动作 |
+| --- | --- | --- | --- |
+| `read-only` | 不连接或不观察正在运行的 DEV 服务，只验证源码、本地 contract、fixture、mock、dry-run 或静态输出。 | `git diff`、`rg`、类型检查、unit/contract test、CLI `--dry-run`、生成计划或补文档。 | 访问 live service、触发任务、写数据库、部署、重启、rollout、真实硬件或虚拟硬件动作。 |
+| `live-read` | 读取正在运行的 DEV 服务、日志、health、status、metrics、Kubernetes 只读对象或只读 API，不改变 live 状态。 | `GET /health`、`GET /status`、只读 proxy、`kubectl get/describe/logs`、只读 CLI status/diagnostics。 | `POST/PUT/PATCH/DELETE`、`kubectl apply/delete/rollout restart`、触发 schedule/job/task、写 issue/PR 之外的 runtime 状态、任何会创建 operation/audit/evidence 的动作。 |
+| `live-mutating` | 在 DEV 环境执行会改变 live 状态的命令，即使目标是 smoke、复测或诊断。 | 经 prompt 明确授权的 dev deploy/apply/rollout、trigger/run/retry、task submit/steer、写配置、创建 operation/audit/evidence、HWLAB M3 DO/DI 链路触发。 | 任何未被 prompt 精确列出的 live mutation；生产写入、密钥读取、数据库手工 patch、Code Queue 高风险干预仍按更高安全边界处理。 |
+
+`DEV smoke`、`M3 smoke`、`live smoke`、`复测`、`验证` 这类词本身不构成 live mutation 授权。只要命令会改变 DEV runtime、触发真实或虚拟设备动作、创建任务/operation/audit/evidence、改变 deployment 或写入服务状态，就必须归入 `live-mutating`。
+
+派单 prompt 必须显式写出：
+
+- `DEV test class`：只能是 `read-only`、`live-read` 或 `live-mutating`。
+- `允许的 live mutation`：若 class 是 `live-mutating`，必须逐项列出允许的命令形态或动作、目标环境/服务/namespace、可接受的状态变化、观察和回滚步骤；若没有授权，写 `none`。
+- `禁止动作`：至少说明 prod mutation、密钥明文、数据库手工 patch、Code Queue backend 重启/重建、运行中任务 interrupt/cancel 是否禁止；未写明的高风险动作一律禁止。
+- `closeout 字段`：runner final response 必须报告实际执行的 test class、是否发生 live mutation、执行命令摘要、目标环境、证据链接或 ID，以及未覆盖风险。
+
+runner 收到未分类或含糊的 prompt 时，只能执行 `read-only` 范围；如果完成任务需要 `live-read` 或 `live-mutating`，必须停在计划和待授权状态，列出拟执行命令、风险和需要指挥官补充的授权，不能自行把“DEV”解释成允许写入。
+
+supervisor closeout 不能只看 runner 的成功自述，必须核对 prompt 授权和实际命令级别：
+
+- `read-only` closeout 应证明没有 live service 写入，证据来自 diff、静态检查、unit/contract test 或 dry-run 输出。
+- `live-read` closeout 应记录读取的 DEV endpoint、service、namespace 或日志范围，并明确没有触发 runtime 状态变化。
+- `live-mutating` closeout 应指出 prompt 中的明确授权、实际变更目标、operation/audit/evidence/task/job ID、回滚或恢复观察，以及 prod 未触碰。
+- 如果 runner 在没有明确 prompt 授权时执行了 live mutation，即使 smoke 结果成功，也不能把任务验收为正常完成；指挥官应先核实 live 状态和 blast radius，再把它记录为治理缺陷或 follow-up，并修正后续 prompt 模板。
+
+HWLAB M3 口径使用同一分级：只读报告、fixture、LOCAL/DRY-RUN 和 diagnostics 只能算 `read-only` 或 `live-read`；触发 `res_boxsimu_1:DO1 -> hwlab-patch-panel -> res_boxsimu_2:DI1` 的可信闭环属于 `live-mutating`，必须有 prompt 明确授权并在 closeout 中给出 operation / audit / evidence 关联。

 `codex submit --dry-run` 是派单前的轻量 preflight。它输出 `routingRecommendation`、`policyContract` 和模型注册表，帮助指挥官看到推荐 runner/model、风险信号、缺失的 prompt guard、模型分层、并发上限、`opencodeModels` 和 `modelPorts`；它不会修改真实提交 payload，也不会替代指挥官判断。真实派单是否使用 `--model minimax-m2.7`、`--model deepseek-chat` 或 `--model gpt-5.5` 仍由指挥官显式决定。

+
 并发治理按模型和风险一起决定。GPT-5.5 常规并发目标是 5 条 lane；当写入范围互不重叠、heartbeat/trace 健康、完成质量稳定时可以短时提高到 10。MiniMax 只承接简单任务时可以提高到 10，但必须保留指挥官审阅和证据核验。DeepSeek 用于中等复杂度任务，默认按约 5 条 lane 观察质量，再根据成功率和 reviewer 负载逐步调整。并发扩张的前提永远是任务质量和可观测性，而不是模型价格。
