+## 中文
+
+QuantStrategyLab 部署运行设置的声明式 schema 和工具仓库。
+
+这个仓库用于描述和校验“哪个平台运行哪个策略”的配置格式，但不保存真实线上运行分配、策略逻辑、券商执行代码、凭据或密钥。
+
+## 公开仓库策略
+
+真实 target 文件不能提交到这个公开仓库。真实部署选择应保存在 GitHub Variables / Environments、GitHub Secrets、Secret Manager，或放在被忽略的 `local/` 目录下。
+
+非敏感运行选择，例如 `TARGET_SPEC_JSON`、`RUNTIME_TARGET_JSON` 和插件挂载声明，可以放在 repository 或 environment variables 中。凭据、token、private key 等必须使用 secrets。
+
+如果某个部署需要私有校验策略，请放在被忽略的本地文件里，例如 `local/policy.json`。
+
+## 边界
+
+- `UsEquityStrategies` 负责分配逻辑、策略默认值和风险规则。
+- 平台仓库负责券商 adapter、运行时输入采集、通知和执行。
+- 本仓库负责运行 target 的 schema、示例、校验和渲染工具。
+- 本仓库不保存 secret value；需要时只引用 secret name 或平台仓库自身的 secret。
+
+## 命令
+
+校验示例；如果存在 `local/targets/**/*.json`，则优先校验本地 target：
+
+```bash
+python3 scripts/runtime_settings.py validate
+```
+
+渲染一个示例 target：
+
+```bash
+python3 scripts/runtime_settings.py render examples/targets/schwab/live.example.json
+```
+
+预览被忽略本地 target 对应的 GitHub variable 更新：
+
+```bash
+python3 scripts/runtime_settings.py apply local/targets/longbridge/sg.json
+```
+
+实际应用 GitHub variable 更新：
+
+```bash
+python3 scripts/runtime_settings.py apply --yes local/targets/longbridge/sg.json
+```
+
+`RUNTIME_TARGET_JSON` 是唯一 canonical source。兼容变量，例如 `STRATEGY_PROFILE`，由它生成，避免多个配置源互相漂移。
+
+## 架构
+
+这个仓库在策略选择和平台部署之间提供一个轻量 bridge，同时避免公开真实运行分配：
+
+- target 文件声明期望的运行目标。
+- validator 检查必填运行字段和插件挂载是否一致。
+- 可选的 ignored local policy 可以添加私有策略/插件要求。
+- renderer 把声明转换成平台专属 GitHub variables。
+- 平台仓库保持现有 adapter 代码，并消费生成后的变量。
