 # MapLibreParticlePackageConsumerTestHost
 
-这是发布包 Consumer smoke host，不引用 `packages/`、Test Host bridge 源码、MapLibre Native source tree 或 workspace dependency。其 `package.json` 只直接依赖 `@navsea/maplibre-particle-rn@13.4.1-particle.1`；Map、Camera、WeatherRuntime 和 style helper 全部从该发布包导入。
+这是正式发布包 Consumer 验收 Host。它用于模拟 NavSea 的升级方式：Consumer 只直接安装 `@navsea/maplibre-particle-rn@13.4.1-particle.1`，由该 npm 包接入 React Native，并由 Gradle 从 `https://pbf.jpcn.ccwu.cc/maven` 解析正式 Particle AAR。
 
-最终 registry 未决定时，先在包目录生成 tarball，再在本目录手工执行：
+禁止直接依赖 `@maplibre/maplibre-react-native`、旧 `weather-runtime-bridge`、MapLibre Native source tree、Maven Local、本地 AAR 或 workspace/source-path bridge。Map、Camera、WeatherRuntime 统一从 `@navsea/maplibre-particle-rn` 导入。
 
-```bash
-npm install /absolute/path/navsea-maplibre-particle-rn-13.4.1-particle.1.tgz --save-exact
-npm install --ignore-scripts
-npx expo prebuild --platform android --clean
-npx expo run:android
-```
+当前验收数据复用 STEP-062 已通过的真实 WeatherV2 fixture：ECMWF HRES 20260807，513×769，T0/T1/T2/T3 四个 canonical `float32-le / interleaved-uv` 风场。`.f32` 通过 Expo Asset materialize 为本地 `file://` URI 后提交给 WeatherRuntime，payload 不进入 JS 数组。
 
-该 `.tgz` 是发布物而非源码路径。Android 正式 artifact 已发布到 `https://pbf.jpcn.ccwu.cc/maven`；package plugin 会自动加入该仓库，并将 MLRN 的唯一 OpenGL SDK 请求替换为 `cc.navsea.maplibre:android-sdk-particle-opengl:13.4.1-particle.1`。
+验收目标是同时看到 GSI 底图、WeatherColor 与 Particle，并确认 T0～T3 顺序接受、Runtime 进入 READY。这样验证的是“正式 npm 包 → 正式 Maven 仓库 → 正式 AAR → RN/Native/Core”的完整升级链，而不是源码工程或开发期 AAR。
