The transcript's "Review" affordance is a promise: tapping it leads to a
decision still there to be made. For a FROST signing proposal it was only
ever withdrawn one way -- and a proposal can be processed three.
**How a request was closed.** RitualNotice drops the tint and the call to
action when the request is answered, and a request counts as answered when
the step it asked for has since been published by this device:
FROST_REQUEST_FULFILMENTS = mapOf(TYPE_FROST_APPROVAL_NEEDED to TYPE_FROST_NONCE)
Approving publishes a nonce, so approving closes it. Nothing else does.
**Declining.** decline() fails the session and broadcasts a FAILURE. It
publishes nothing of the member's own, by design -- a refusal is a refusal.
So no fulfilment line is ever written, and the request went on asking, in
primary tint, for a decision the member had already made. Tapping it
reached a screen with no buttons on it, which was the screen being right.
**A quorum that did not need them.** A t-of-n key finishes without
everybody. The coordinator takes the first t nonces, and a member whose
phone was in a pocket is simply not among them -- but advance() returned at
the approval gate on their device, so the arriving SIGNATURE was stored and
nothing was done with it. Their session sat at COLLECTING_NONCES forever.
The request stayed lit, the screen still offered Sign and Don't sign, and
both answers were wrong: a nonce nobody was waiting for, or a refusal that
would flip a COMPLETE session to FAILED on every device and announce
"Nothing was signed" to a group holding the signature. fail() writes the
stage with update() rather than moveTo(), so that last one was reachable.
**The transcript.** A request is now closed by being *answered* or by being
*settled* -- a frostComplete or frostFailed line after it. The two are kept
apart deliberately. Answered keeps the tick; settled does not, because the
member never answered and crediting them with a signature they refused, or
were never asked for, is worse than the summons was. Both rules moved out
of the composable onto ChatMessage, where they are stated once and tested.
Settlement is signing-only: a ceremony step can only be taken or waited
for, so a DKG request has no equivalent and reading one from a signing
session's end would drop a summons the ritual is still stalled on.
**The session.** The transcript alone could not close the third case: the
device that never approved wrote no terminal line to read. advance() now
completes on a signature that has already arrived, ahead of the approval
gate rather than below it. That gate is there to keep this device's own
material off the wire, and finishing puts none there -- it verifies the
aggregate, applies the event and announces, all from what is already
stored. Everything it now skips on that path is work the signature made
pointless anyway: a late nonce, a partial signature nobody will aggregate.
Three things follow. isAwaitingApproval reports false, so FrostSigningScreen
hides the buttons -- it now asks the manager rather than re-deriving the
rule, which had drifted into a second copy of it. A late "Don't sign"
cannot abandon a signature that exists. And the signed event finally lands
locally for a member who never approved: applySignedEvent sat below the
gate and was being skipped, so a dialect the group signed without them
never reached their store.
Verified: :composeApp:compileDebugKotlinAndroid succeeds, and
:composeApp:testDebugUnitTest passes -- 165 tests, 16 of them new. Eight
cover the transcript rules against a hand-built row list; eight cover
isAwaitingApproval, including the settled-signature case. What stays
uncovered is advance() itself, which is Room-backed.

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.
