Phase 3 of docs/chapter-uploads.md, and the second fix to something wrong today. A chapter's index is signed into the event and cannot be recounted on arrival: a device applying one cannot recount from a version other members may have added to in a different order. So the number has to be right when the chapter is proposed, and `getChaptersForArtifactVersion(...).size` is not it -- a proposed chapter is not a row until a quorum signs it, so two proposals a second apart read the same table and are signed at the same index. At one chapter at a time that is a race nobody hits. An upload of twelve files hits it eleven times out of eleven. The information was already published. A session's items carry the unsigned events it is signing, and an unsigned event's fields are settled at proposal time -- which is the whole reason FrostSigningRepository.unsignedEvents exists rather than only signedEvents. So ChapterIndexing.nextIndex reads the table and the room's proposals, and returns one past the highest rather than a count: a count is wrong the moment the sequence has a gap, and a chapter that failed to reach a quorum leaves one. Three things that are easy to get wrong and are tested. Every session counts whatever stage it is at, because filtering would trade a harmless gap for a collision with a stalled session that still completes. Items are filtered by kind, because a chunk carries an index too -- its position in the chapter -- and reading those as chapter indices puts the second chapter of a two-paragraph first chapter at 2. And proposals are scoped by the artifactVersionId tag, because the row query is scoped by version while observeSessionsForChatRoom returns the whole room. This fixes one device, not the group: two members proposing at the same moment still collide, and no amount of local reading will change that. That is tolerable where this was not -- an index orders reading, two chapters at index 4 sort arbitrarily between themselves, and nothing else breaks. 951 tests, no failures.

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.
