The parent card on a room's detail screen read "Parent group" over sixteen hex characters. Every other card naming a room names it -- `SubgroupCard` has shown `room?.chatRoom?.subject` since subgroups landed -- and the one card pointing the other way up the lineage did not, although the room it points at is usually right there in the database. So: "Parent group" moves to the overline, the group's name becomes the headline, and the truncated id moves underneath, where it can still be read against what the lineage says. The label keeps its place rather than being replaced, because a card carrying a name and nothing else says nothing about which way the lineage runs, and the signing key's card -- same icon column, same shape -- sits directly above this one. **The name can only come from the room, and there is not always one.** A birth certificate names the child and never the certifier, so a member of the subgroup who is not also in the group above holds a verified lineage with nothing to call it by. That case keeps the card it already had: the id as the headline, no supporting line. It is not a corner -- it is the ordinary position of anyone welcomed into a subgroup rather than founding one -- so the room is a nullable field rather than something to wait for. `SubgroupManager.parentGroupsOf` is `parentsOf` with each id looked up, returning `Parent(chatRoomId, room)` the way `subgroupsOf` returns `Subgroup`. The verified set and its canonical order are untouched; a parent whose room is missing stays in the list. The id-only `parentsOf` stays as it is, because `offersTo` compares ids and should not pay for rooms it will not read. Three tests: a parent this device is in is named by its room, one it is not in is still listed with nothing to name it, and two parents keep the lineage's own order -- asserted against `parentsOf` rather than a written-out order, since canonical means sorted by id and nobody should have to know how two derived ids sort. 459 common tests, 985 jvm tests, `m3Audit` meets every budget.

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.
