Phase 1 of docs/npub-sign-in.md. A type change and nothing a user can see. Identity.nostrPrivateKey becomes nullable and nostrPublicKey becomes a constructor field, because the kind this plan adds -- NostrPublic, a bare public key -- has nothing to derive a pubkey from. A data class would let the two disagree, so two checks in init refuse an identity whose kind and key disagree about whether there is one, and one whose key does not derive the public key it was given. Identity.signing derives the pubkey and refuses the read-only kind; Identity.readOnly builds the other; nothing else constructs one now. The id of a read-only identity is toWalletId() of the x-only key -- the same id its nsec would have -- which is what will let a read-only identity become a signing one and keep its preferences. canSign is a property of the identity rather than nostrPrivateKey != null at each site, so that a signer with no local key has one place to answer. Every reader of the key already reached it through ?. on a nullable identity, so the compiler forces nothing here; the sites that need a decision are the plan's Phase 5, found by reading. The one site that did change is KeyRecoveryScreen, whose two whens branched on NostrSecret with an else that meant "mnemonic": both are exhaustive now, so the new kind is not handed the phrase option by default. Tests: NavigationIdentityRoutingJvmTest gains a read-only fixture with the same id and pubkey as the secret one, the routing case for it (by its account, like any other), and the three refusals plus the factory's own.

This is a Kotlin Multiplatform project targeting Android, iOS, Desktop (JVM).
-
/composeApp is for code that will be shared across your Compose Multiplatform applications. It contains several subfolders:
- commonMain is for code that’s common for all targets.
- Other folders are for Kotlin code that will be compiled for only the platform indicated in the folder name. For example, if you want to use Apple’s CoreCrypto for the iOS part of your Kotlin app, the iosMain folder would be the right place for such calls. Similarly, if you want to edit the Desktop (JVM) specific part, the jvmMain folder is the appropriate location.
-
/iosApp contains iOS applications. Even if you’re sharing your UI with Compose Multiplatform, you need this entry point for your iOS app. This is also where you should add SwiftUI code for your project.
Build and Run Android Application
To build and run the development version of the Android app, use the run configuration from the run widget in your IDE’s toolbar or build it directly from the terminal:
- on macOS/Linux
./gradlew :composeApp:assembleDebug - on Windows
.\gradlew.bat :composeApp:assembleDebug
Build and Run Desktop (JVM) Application
To build and run the development version of the desktop app, use the run configuration from the run widget in your IDE’s toolbar or run it directly from the terminal:
- on macOS/Linux
./gradlew :composeApp:run - on Windows
.\gradlew.bat :composeApp:run
Build and Run iOS Application
To build and run the development version of the iOS app, use the run configuration from the run widget in your IDE’s toolbar or open the /iosApp directory in Xcode and run it from there.
