# Platform strategy

The project has two portable layers and thin launchers:

1. The Rust semantic compiler builds the same typed schema on every platform.
2. The shared Compose component library renders that schema without HTML.
3. Platform launchers own only lifecycle and operating-system integrations.

# Supported build direction

Platform	Shared runtime	Platform-specific responsibilities
Android	Compose + semantic schema	Keystore, background upload, shares, notifications, camera and calls
iOS	Compose + semantic schema	Keychain, background transfer, share extension, notifications and CallKit
Windows	Compose Desktop	Credential Manager, file integration, notifications and packaging
macOS	Compose Desktop	Keychain, Finder integration, notifications and packaging
Linux	Compose Desktop	Secret Service, file integration, notifications and packaging

The current build enables the desktop JVM target because it can be compiled and tested on this Linux workstation without downloading an Android SDK. All UI code lives in commonMain, so adding Android and iOS targets must not require moving or duplicating components.

No shared module may import Android, Apple, Windows or Linux APIs. Those belong behind platform interfaces in their respective source sets.
