`babel-preset-expo` inlines `EXPO_PUBLIC_MOBILE_SHELL` into `mobileShellBuildKind` at transform time (babel-preset-expo/build/inline-env-vars.js:51), but nothing Metro hashes into the transform cache key carries that value: the key is `metro/src/DeltaBundler/getTransformCacheKey.js:21`, whose inputs are the Metro version, `cacheVersion`, the transformer path and `@expo/metro-config/build/transform-worker/metro-transform-worker.js:600`, none of which reads the environment. A release assembled after an opposite-kind build reuses the warm entries and bakes the wrong shell, and the absence of the variable's name in the bundle cannot tell the two apart. The newest published `@expo/metro-config` (58.0.4) keys it no differently. Folds the kind into `cacheVersion`, by the same `=== 'ota'` rule the app applies, keeping Metro's own version as the prefix. Proven with four `expo export --platform android` runs against an isolated Metro cache. Before: `ota` then `native` produced byte-identical bundles, both `return 'ota'`. After: the second run returns `'native'` under a different bundle hash. Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb
