 第一阶段 CaseRun 不引入常驻调度服务，由 `hwlab-cli case` 组合 case registry repo、本地 `.state`、`hwpod-cli`、`hwpod-compiler-cli`、`hwlab-api` 和在线 `hwpod-node` 完成单次运行。标准 case registry repo 是 `pikasTech/hwlab-case-registry`，本地默认 checkout 路径是 `/root/hwlab-case-registry`；历史 `pikasTech/hwpod-cases` 只作为迁移前来源。case registry repo 提供 `cases/<caseId>/case.json` 与同目录 `hwpod-spec.yaml`；每次运行会把 spec 复制到 `.state/hwlab-cli/caserun/<runId>/.hwlab/hwpod-spec.yaml`，形成隔离的 run-local spec。
 
-CaseRun 的 case registry repo 与 subject repo 必须分离。case registry repo 只保存 `case.json`、HWPOD spec 或 spec 引用、subject 引用、期望结果和 `runs/<caseId>/<runId>/` 审计产物；它不保存或替代实际固件、工程、测试样例或产品代码库。subject repo 是被开发、被测试、被编译或被下载验证的真实源码仓库，由 `case.json` 通过 `subject` 字段引用独立 Git repo、ref 和 subdir；`source` 作为旧字段名只用于迁移兼容，不再作为新 case 的标准命名。`case run` 准备阶段必须把 subject ref 解析为固定 subject commit，复制或 checkout 到 run-local workspace，再从隔离副本执行 build/download/smoke。`branch` 或 `tag` 只能作为人工入口，`evidence.json` 必须记录 subject repo、subject commit、subdir 和 run-local workspace，避免把 floating ref 或外部脏 workspace 当作可审计证据。
+CaseRun 的 case registry repo 与 subject repo 必须分离。标准 registry repo 是 `pikasTech/hwlab-case-registry`，G14 标准 checkout 是 `/root/hwlab-case-registry`；历史 `pikasTech/hwpod-cases` 和 `/root/hwpod-cases` 只作为迁移前来源，不再作为新 CaseRun 入口或写入目标。case registry repo 只保存 `case.json`、HWPOD spec 或 spec 引用、`subject` 引用、期望结果和 `runs/<caseId>/<runId>/` 审计产物；它不保存或替代实际固件、工程、测试样例或产品代码库。subject repo 是被开发、被测试、被编译或被下载验证的真实源码仓库，由 `case.json` 通过 `subject` 字段引用独立 Git repo、ref 和 subdir；`case run` 准备阶段必须把 subject ref 解析为固定 subject commit，复制或 checkout 到 run-local workspace，再从隔离副本执行 build/download/smoke。`branch` 或 `tag` 只能作为人工入口，`evidence.json` 必须记录 subject repo、subject commit、subdir 和 run-local workspace，避免把 floating ref 或外部脏 workspace 当作可审计证据。
 
 CaseRun 是强化学习 Harness 的最小执行单元，但它本身不是完整 epoch。完整 epoch 还需要样本选择、策略生成、奖励/评价、批量调度、跨 run 归因和自动训练闭环；第一阶段只要求一个 `caseId` 能从 case registry repo 进入真实 HWPOD 编译闭环，并把可审计产物稳定落盘。
