Summary

• OnboardingViewModel now lives in the activity's ViewModelStore (rememberOnboardingViewModel), so its onCleared runs when the activity finishes, while every onboarding flow keeps sharing the one instance.

Motivation

• BoxLoreAppRoot created the view model with remember, outside any ViewModelStore, so it was never cleared. onCleared is where Echo and deck requests are cancelled, the clip pool is released and an unfinished onboarding is reported (onboarding_abandoned). Analytics confirm the gap: that event has never been received.
• The single root-level instance is deliberate: search, Echo (AI), genre picks, the import sheet, Home's AI entry and the sign-in detour through Settings all share it, so shows picked in one flow carry over to the others. The fix keeps that.

What changed

• New ui/rememberOnboardingViewModel(owner, build): viewModel(viewModelStoreOwner = owner, key = "boxlore-onboarding", factory = …). build runs once per store; every call site gets the stored instance.
• BoxLoreAppRoot uses it with the activity as owner; everything that received the instance (onboarding route, import sheet, Home's AI entry, Settings back handling) is unchanged.
• app/README.md and feature/onboarding/README.md describe the new scope (the onboarding README described the old remember behaviour).

Behavior & compatibility

• No visible change for listeners: one onboarding instance per activity, shared as before. It now also survives activity recreation (e.g. a locale change), which remember did not.
• When the activity finishes during onboarding, pending Echo work stops and onboarding_abandoned is sent once (only if onboarding was started and isn't complete). Process death without the activity finishing still sends nothing, as with any ViewModel.
• Adaptive states: MainActivity handles size, orientation and fold changes itself, so window transitions on phones, tablets and foldables keep the same instance; the ViewModelStore also keeps it across recreation.

Release copy

Fixed

• OnboardingViewModel lives in the activity's ViewModelStore (rememberOnboardingViewModel), so onCleared cancels Echo work and reports unfinished onboarding as onboarding_abandoned; every onboarding flow still shares the one instance.

Test plan

• Release build installed on a phone
• OnboardingViewModelScopeTest (Robolectric, real OnboardingViewModel): one instance across call sites and leaving/returning; finishing the activity mid-onboarding reports abandoned once and cancels its scope; finished or never-started onboarding reports nothing. With the old remember creation, two of these fail (3 instances; no abandoned event).
• OnboardingViewModelRecreationTest (real ComponentActivity): recreating mid-onboarding keeps the same view model and its picked shows and sends nothing; finishing afterwards sends onboarding_abandoned once. Both fail with remember.
• cx.aswin.boxlore.navigation.* tests (96), :app:ktlintCheck and detekt pass
• Manual: pick shows in search, switch to Echo and back, picks remain; back out of the app mid-onboarding, onboarding_abandoned arrives

Summary

Summary by CodeRabbit

• Bug Fixes
  • Onboarding now uses one activity-scoped view model across onboarding flows, preventing its state and work from being tied to an individual composition.
  • Leaving the activity during an unfinished onboarding flow reports abandonment once; completed or unstarted flows are not reported as abandoned.
• Documentation
  • Updated onboarding lifecycle guidance to describe the shared instance and its cleanup when the activity finishes.

The app now obtains the onboarding view model from the activity’s ViewModelStore. Tests check reuse across onboarding entry points and behavior when the store is cleared.

Changes: Activity-scoped onboarding

Layer / File(s)	Summary
Activity-scoped lookup and root wiring app/src/main/java/cx/aswin/boxlore/ui/OnboardingViewModelScope.kt, app/src/main/java/cx/aswin/boxlore/ui/BoxLoreAppRoot.kt, app/README.md, feature/onboarding/README.md	A new composable helper retrieves the onboarding view model from the supplied owner’s store with a fixed key and a factory that calls build(). BoxLoreAppRoot supplies the activity as owner. The documentation describes the shared, activity-scoped lifecycle and warns against using remember.
Reuse and lifecycle tests app/src/test/java/cx/aswin/boxlore/ui/OnboardingViewModelScopeTest.kt	Tests check that onboarding entry points reuse one view model. They also check abandonment reporting and scope cancellation when the store is cleared, and verify that completion or no onboarding start emits no abandonment event.

Verify that in-progress onboarding survives activity recreation without reporting abandonment before merging. The existing tests do not cover that lifecycle transition.

Full details: Title check

Explanation

The title "fix(app): keep the onboarding view model in the activity's store" follows Conventional Commits with an allowed type (fix) and scope (app). It describes the main change: the OnboardingViewModel moves from a remember-created instance into the activity's ViewModelStore via rememberOnboardingViewModel. It is 64 characters, under the ~72 limit. The description uses a noun phrase rather than an imperative verb after the colon, so it does not fully meet the imperative-mood rule.

Full details: Architecture Compliance

Explanation

The PR adds activity-scoped ViewModel ownership in :app. It does not change feature or catalog dependencies, create a second playback repository or app graph, or alter identity or storage contracts. The activated onCleared code cancels work and records analytics.

Full details: Jvm Tests For Changed Logic

Explanation

The PR adds JVM regression tests for ViewModel reuse and store cleanup. The tests also cover completed and never-started onboarding. They use Robolectric, an in-memory database, and a recording analytics sink.

Full details: Description check

Explanation

The description states the change: OnboardingViewModel moves into the activity's ViewModelStore via rememberOnboardingViewModel so onCleared runs on activity finish, while onboarding flows keep sharing one instance. It also gives motivation, the files and documentation touched, compatibility notes, and a test plan. It matches the changeset in the summaries (OnboardingViewModelScope.kt, BoxLoreAppRoot.kt, README updates, OnboardingViewModelScopeTest.kt).

Full details: Docstring Coverage

Explanation

Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 1 functions across 3 files. (2 skipped: 2 unsupported.)

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

- Around line 89-93: Extend the onboarding retention tests with a Robolectric
test that recreates the activity during an in-progress flow. Use the real
activity-owned ViewModel lifecycle rather than the synthetic store owner in the
current test, then verify the recreated activity retains the same ViewModel and
selections and emits no abandonment event.
