// materializes a filtered mirror into build/sharedSrc and that directory is added as a source
// root. The app sources remain the single source of truth; extend the include list below (don't
// copy files into wear/src) when the compiler reveals a missing transitive dependency.
// Deliberately excluded: ui (except the DebugSettingsManager the mesh layer references),
// onboarding, nostr (except pure-Kotlin Bech32), net, geohash, wifi-aware, hotspot, voice
// features, and the phone's foreground service.
