+# NOTE: every job here fails on a clean checkout until PureSwift/AndroidBluetooth#4 is merged.
+# AndroidBluetooth requests the `AndroidManifest` product from `Android`, but it moved to
+# `swift-android-native` (PureSwift/Android#40), and SwiftPM validates the whole package graph even
+# for dependencies that are conditional on `.android`:
+#   error: product 'AndroidManifest' required by package 'androidbluetooth' ... not found
+# That is a one-line manifest fix upstream, not a problem with this repo.
