Estimated code review effort: 1 (Trivial) | ~5 minutes Mergeability Score: 🔵 Low · up to This PR upgrades the Compose stack but keeps the forced AndroidX Compose version at 1.12.0 instead of the matching 1.12.0-rc01 version, which could create dependency compatibility issues; it is mergeable with owner awareness and follow-up to align those versions.

catalog from 1.12.0 to 1.12.0-rc01 so AndroidX Compose artifacts match the

Reverts d8361cc, restoring #6662's bump now that every regression it caused has a fix on main: - #6666 settles asynchronous resource loads in the 8 tests that failed deterministically (:core:service, :feature:connections) - #6669 keeps ViewModel coroutines inside the test that started them, covering ConnectionsViewModelTest and RadioConfigViewModelTest - #6668 removes the runBlocking getString shim from every Dispatchers.Default-reachable notification path, which is what made the bump a production hazard rather than only a test one Also drops the Renovate rule that blocked 1.12.0-rc01, since its lift condition is now met.

Every artifact pinned to the androidx-compose-bom-aligned catalog ref must be in the compose-multiplatform group: bumping one rewrites the shared ref, which resolutionStrategy force-aligns across all of androidx.compose. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Why
Re-lands the CMP 1.12.0-rc01 bump (#6662, reverted by #6664). Every regression it caused now has a fix on
main, and the Renovate rule that blocked the version has met its stated lift condition.The original bump broke 10 distinct tests through one mechanism:
compose-resourcesAsyncCache.getOrLoadstopped resolving inline on the caller's dispatcher and now loads on a privateCoroutineScope(SupervisorJob())— i.e.Dispatchers.Default. Every cold resource read became a real cross-thread hop thatadvanceUntilIdle()cannot drain. Three PRs addressed it::core:service,:feature:connections)ConnectionsViewModelTestandRadioConfigViewModelTest, the two that failed intermittentlyrunBlockinggetStringshim from everyDispatchers.Default-reachable notification path#6668 is the one that mattered beyond tests. Under this bump, the blocking shim could wedge
Dispatchers.Defaultpermanently — everygetStringin the process hanging forever, main thread included, at a concurrency threshold equal to CPU count (so an 8-core phone wedges at 8, easier than a dev machine).ServiceScoperuns the packet/notification pipeline onDispatchers.Default, so a message burst was the trigger. That is fixed onmain, which is what makes this bump safe to carry rather than merely green.🛠️ Changes
d8361ccd1:compose-multiplatform1.11.1 → 1.12.0-rc01,compose-multiplatform-material31.11.0-alpha07 → 1.12.0-alpha03,androidx-compose-bom-aligned1.11.4 → 1.12.0.androidx.compose.ui:ui-text-google-fontsto thecompose-multiplatformRenovate group. It is pinned to theandroidx-compose-bom-alignedcatalog ref but was the only such artifact missing from that group, so Renovate opened a solo bump for it (chore(deps): update androidx.compose.ui:ui-text-google-fonts to v1.12.0 #6651) that rewrote the shared ref and force-aligned all ofandroidx.composeto 1.12.0 while CMP stayed at 1.11.1. That skew broke screenshot preview discovery (RuntimeExceptionatPreviewAnnotationDescriptor.kt:138,initializationErroron every text-input preview). Fixing the grouping here disarms the trap instead of leaving it for the next divergence.Testing Performed
The verification that had not been done anywhere: all 10 previously-failing tests, on this branch, i.e.
main+ all three fixes + the bump together. Each run in a separate invocation with--rerun-tasksso nothing came from the build cache, and CMP confirmed as1.12.0-rc01first.@Testcount:feature:connections:jvmTest --tests "*ScannerViewModelTest*":feature:connections:testAndroidHostTest --tests "*AndroidScannerViewModelBondingTest*":core:service:testAndroidHostTest --tests "*MeshNotificationManagerImpl*":core:ui:jvmTest --tests "*ConnectionsViewModelTest*":feature:settings:jvmTest --tests "*RadioConfigViewModelTest*"127 tests, 0 failures. Counts read from the JUnit XML with an XML parser rather than a regex, since a regex over
<testcase>...</testcase>mis-associates failures across self-closing elements and produced wrong numbers earlier in this work.The
@Test-count column is deliberate: this repo runs DevelocitytestRetrywithmaxRetries = 2andfailOnPassedAfterRetry = false, so a test that passes only on retry still reports green — and the task is then cached, making the mask persistent. A reported count equal to the source count proves no retries fired, so none of these passes is a retry flip.Note for review
Rebased onto
mainatb4bedd92f, which now contains #6670. The pre-rebase CI run failed exactly one test —NodeDetailCompassLifecycleTest.compassSelectionFollowsScreenLifecycleAndDismissal,ComposeTimeoutExceptionatNodeDetailCompassLifecycleTest.kt:92— and #6670 is precisely its fix (barewaitUntil { … }→waitUntil(label, SETTLE_TIMEOUT_MS), since the 1s default asserts rendering speed rather than liveness).merge-base --is-ancestorconfirmed the old base did not contain it. That was the only failing test in the entire run, so the flaky-coin-flip caveat this section used to carry no longer applies.Post-rebase local verification:
:feature:node:allTests,spotlessCheck,detekt, andvalidateDebugScreenshotTestall pass. The compass result was read from the JUnit XML (tests="1" skipped="0" failures="0" errors="0", zero<failure>elements) rather than inferred fromBUILD SUCCESSFUL, so it is a genuine execution and not a cached or retried pass.🤖 Generated with Claude Code
