feat(wear): count watch use on the phone and offer Send to watch only in reach - #1263
The watch button on the episode page shows only while boxlore on a watch is in reach of the phone.
The phone now counts Wear OS use from what passes through the watch link. The watch app sends no usage events of its own.
Motivation
The button stayed once a watch had ever linked. With the watch away, a tap could only answer "Your watch isn't in reach", so the button offered something it could not do.
There was no way to tell whether the watch app is used. Sending events from the watch would cost its battery and network; the phone already sees the link's traffic.
What changed
WearLinkStatus.inReach (:core:wearlink): a watch has linked and can be reached now. watchEpisodeActions and watchPlayOffer (:app) both go by it, so the episode page and the players follow one rule.
PhoneLinkEvents / PhoneLinkEvent (:core:wearlink): a port the link reports through. PhoneWearLink and PhoneWatchDownloads report a first contact, each answer to a sign-in request, each Send to watch or Remove from watch order, playback moving either way, and each merge of the watch's changes.
WatchAnalyticsTracks (:core:analytics) with five events: watch_linked, watch_sign_in_answered, watch_episode_order, watch_playback_moved, watch_changes_merged. They carry outcomes and counts only: no episode, show, account or sign-in code.
PhoneLinkAnalytics (:app) maps the port onto those events and keeps a failing analytics call away from the link.
Behavior & compatibility
With the watch away, the episode page shows no watch button, and so no "On your watch" mark; both return when the watch is back in reach.
The header keeps its layout: the title already makes room for the button only when it is shown. Phones, tablets and foldables share this header; nothing else in it moves.
Listening on a watch that never meets the phone is not counted.
Event budget: the five events are estimated at 0.11 a month per active install together, since only installs with a linked watch send them.
Release copy
Added
Wear OS usage events sent by the phone (WatchAnalyticsTracks), reported by the watch link through PhoneLinkEvents.
Fixed
The episode page's watch button follows WearLinkStatus.inReach and is hidden while the watch cannot be reached.
Test plan
JVM: :core:wearlink (new cases in PhoneWearLinkTest, new WearLinkStatusTest), :core:analytics (glossary, emission and budget tests), :app watch-link tests with the new PhoneLinkAnalyticsTest, the repository rule tests; detekt; ktlint on the three modules.
Not seen on a device: the episode page with the watch in reach and away, on a phone or a wide screen; the events arriving in PostHog.
Episode-page watch actions are now available only when the linked watch is currently reachable. They are hidden when the watch is out of range or otherwise unavailable.
Watch-action availability now consistently reflects whether the watch can be reached, rather than whether it has merely been linked. This keeps the controls aligned with the watch’s current connection status.
WearLinkStatus now exposes inReach, which requires the watch to be known and reachable. Watch action availability uses this property. The phone also reports five types of watch-link events through analytics.

Watch action availability and remembered state use inReach. The episode screen and string resource comments describe the in-reach condition.

Summary
Define watch-link events and analytics core/wearlink/src/main/java/cx/aswin/boxlore/core/wearlink/PhoneLinkPorts.kt, core/analytics/src/main/java/cx/aswin/boxlore/core/analytics/*, core/analytics/README.md, core/wearlink/README.md, docs/ANALYTICS_EVENT_GLOSSARY.md
PhoneLinkEvent defines five event types. The analytics glossary, helper methods, emitters, and documentation describe their names and properties.
Record events from phone-watch operations core/wearlink/src/main/java/cx/aswin/boxlore/core/wearlink/PhoneWearLink.kt, core/wearlink/src/main/java/cx/aswin/boxlore/core/wearlink/PhoneWatchDownloads.kt, core/wearlink/src/test/java/cx/aswin/boxlore/core/wearlink/*, core/analytics/src/test/java/cx/aswin/boxlore/core/analytics/*
Phone-watch operations report link, sign-in, episode-order, playback-transfer, and merged-change events. Tests cover event reporting and its conditions.
Forward link events to analytics app/src/main/java/cx/aswin/boxlore/wearlink/PhoneLinkAnalytics.kt, app/src/main/java/cx/aswin/boxlore/AppContainer.kt, app/src/test/java/cx/aswin/boxlore/wearlink/PhoneLinkAnalyticsTest.kt
AppContainer supplies PhoneLinkAnalytics, which maps link events to analytics methods and suppresses tracking failures. A test covers callback failure handling.
The watch button now appears only while the watch is in reach, as intended. Remaining issues are minor: a missing app-level test for the new gate, a playback-transfer analytics event that can be recorded when playback did not start, and an analytics helper file that exceeds the project's size limit. None of them is likely to break user-facing behavior.

Explanation
The description states the purpose and scope of the change. It covers the episode-page watch button gated on WearLinkStatus.inReach, the phone-side Wear OS usage events through PhoneLinkEvents, the five analytics events, the test plan, and the release copy. It is directly related to the changeset.
Full details: Architecture Compliance
Explanation
PR #1263 (boxcreate/boxlore, author ashwkun) was checked against the Architecture compliance criteria in ARCHITECTURE.md. No listed violation was found. - Feature→feature dependencies or imports: None. The only feature/ changes are a code comment in EpisodeInfoScreen.kt and a string comment in strings.xml. No Gradle files changed. - PostHog in feature modules: None. The PhoneLinkAnalytics class in :app calls AnalyticsHelper, which is the :core:analytics façade. The new WatchAnalyticsTracks in :core:analytics uses the existing AnalyticsEmit path. A scan of all added lines found no posthog references. - Hilt, Koin, Dagger, or MockK: A scan of all added lines found none. The new tests (WearLinkStatusTest, PhoneLinkAnalyticsTest, and the PhoneWearLinkTest additions) use plain fakes. - Second PlaybackRepository or AppContainer graph: None. AppContainer.phoneWearLink only passes events = PhoneLinkAnalytics() into the existing PhoneWearLink construction. No new graph is built. - Catalog depending on designsystem or playback: No catalog or build-file changes. :core:wearlink reaches analytics only through the PhoneLinkEvents port, which the :app class implements. - Broken identity or storage contracts: No changes to SharedPreferences files, keys, DataStore, Room, WorkManager names, or deep links. The boxlore_wear_link store (SharedPreferencesPhoneLinkStore) is not modified. PhoneWearLink changes add only event reports and a constructor parameter with a default value. Remaining notes, outside the listed criteria: the PR does not change the ARCHITECTURE.md contracts, and the new watch_* glossary entries are added with matching emission coverage. Adaptive-UI verification and source-file-size rules in ARCHITECTURE.md were not part of this check.
Full details: Module Readme Kept True
Explanation
The PR changes two module contracts that have README coverage: :core:wearlink (new PhoneLinkEvents port, new WearLinkStatus.inReach, new optional constructor parameters on PhoneWearLink and PhoneWatchDownloads) and :core:analytics (five new AnalyticsHelper façades). Both module READMEs were updated in the same PR: - core/wearlink/README.md adds a PhoneLinkEvents bullet to Public API. The README documents no constructor signatures, so the added defaulted parameters do not make it stale. - core/analytics/README.md adds a Wear OS façade bullet for WatchAnalyticsTracks. Event names stay in the glossary, as the README already directs. Other checked items: - Stable names (paths, prefs file and keys, capabilities, analytics persistence keys) are unchanged. The diff adds no keys or paths. - No Gradle or manifest files changed, so the documented dependencies still hold. - Threading: the new note calls run inside the existing coroutines. PhoneLinkAnalytics runs on whatever thread calls it, and AnalyticsHelper is documented as callable from any thread. The README's "ports decide their own threads" rule still applies. - The added README lines contain no dates, history, PR or plan labels, or server and security detail. - watchPlayOffer behaviour is unchanged, since inReach equals watchKnown && reachable. The episode-action change is a bug fix inside :app internals. Advisory, not a failure condition: core/designsystem/README.md line 55 says LocalWatchEpisodeActions "is null without a linked watch." After this PR it is also null when the linked watch is out of reach. The sentence is not false, but it is now incomplete. The check does not cover the designsystem README for a change that is confined to :app wiring, so this does not affect the verdict.
Full details: Jvm Tests For Changed Logic
Explanation
The check applies: the PR adds production logic and fixes a bug. I checked the committed diff against refs/coderabbit/pre-merge-check/base and refs/coderabbit/pre-merge-check/head. Changed production logic and its JVM coverage: - WearLinkStatus.inReach (core/wearlink PhoneLinkPorts.kt) is the bug-fix core. WearLinkStatusTest (new, core/wearlink/src/test) covers the true case and each false case (linked but away, reachable but never linked, neither). It carries a regression comment for the Send to watch regression. - PhoneWearLink event reporting (core/wearlink PhoneWearLink.kt) has new tests in PhoneWearLinkTest. They cover first contact reported once, merges with counts, failed or empty merges reporting nothing, playback direction and only when playback moves, sign-in outcomes for each path, and episode orders with and without the watch in reach. - PhoneWatchDownloads order reporting is exercised by the "Send to watch and Remove from watch" test. - WatchAnalyticsTracks and AnalyticsHelper track methods are exercised by GlossaryAllEventsEmissionTest. - PhoneLinkAnalytics (app) has PhoneLinkAnalyticsTest, which covers failure suppression. Gap: app/.../WatchCrossPlayWiring.kt changes watchPlayOffer and watchEpisodeActions to gate on inReach. No app-level src/test references these functions. The gating rule itself is covered by WearLinkStatusTest, and the wiring change is a small condition swap. The check does not require a test for every wiring line, so this does not establish a failure. A direct test for watchEpisodeActions returning null when inReach is false would strengthen the regression coverage. No Compose or emulator tests are required by this check, and none were used as evidence.
Full details: Title check
Explanation
The title follows Conventional Commits with the allowed type feat and scope wear, and it uses imperative mood. It describes the change in counting watch use on the phone and in offering Send to watch only in reach. Both parts appear in the changeset. However, the title is 78 characters, which exceeds the approximately 72-character limit in the title requirements.
Resolution
Shorten the title to under about 72 characters. For example: "feat(wear): count watch use on phone and show Send to watch only in reach". Also note that the type feat is allowed, so no type change is needed.
Full details: Unresolved Review Threads
Explanation
The check fails because a review thread remains unresolved. - Supplied review metadata returns one CodeRabbit thread on app/src/main/java/cx/aswin/boxlore/wearlink/WatchCrossPlayWiring.kt, line 30. Discussion state is unresolved. Code state is unknown. - The thread asks for app-level JVM regression coverage of the watchEpisodeActions and watchPlayOffer gate. The thread has no recorded dismissal rationale. - Two further findings were generated by the current review and are not yet posted. They are outstanding under this check: - core/analytics/.../AnalyticsHelper.kt (around line 317, Major): the file exceeds the 1000-line source limit. - core/wearlink/.../PhoneWearLink.kt (around line 172, Minor): PlaybackMoved(toWatch = false) can be emitted after a no-op play call. - The prior FAIL stands. Its claim that no threads were returned is contradicted by the current metadata. Its conclusion still holds because the returned thread is unresolved. - This verdict uses only the supplied discussion-state metadata and the stated finding status. It does not assess whether the code has a defect.
Resolution
Before merge: 1. Resolve the CodeRabbit thread on app/src/main/java/cx/aswin/boxlore/wearlink/WatchCrossPlayWiring.kt (line 30). Use one of these paths: - Add an app JVM test under app/src/test. The test must cover that watchEpisodeActions returns null for a known but unreachable watch, returns actions for a known and reachable watch, and that watchPlayOffer follows the same rule. Then mark the thread resolved. - Or dismiss the thread with a short written rationale in the thread, then mark it resolved. 2. Handle the two new findings. Either fix them or dismiss each with a short rationale: - Reduce AnalyticsHelper.kt below 1000 lines. Move private implementation into same-package helpers and keep the public façade signatures. - Emit PlaybackMoved only when the player accepts the playback request. Cover the unresolved-episode path with a test. 3. Confirm that no review thread remains unresolved. Then re-run this check.

watchEpisodeActions and watchPlayOffer: verify a known but unreachable watch
returns null, and a known, reachable watch returns actions. Cover watchPlayOffer
as a shared consumer so the tests fail if either path reverts to the

Resolve the outstanding Minor finding before merge. Use one of these two paths:
1. Add an app JVM test under `app/src/test`. The test should cover: -
`watchEpisodeActions` returns `null` for a known but unreachable watch. -
`watchEpisodeActions` returns actions for a known, reachable watch. -
`watchPlayOffer` follows the same rule. 2. Or dismiss the finding with a short
written rationale. Record the rationale in the review thread. After either path,
mark the finding resolved.

The watch app sends no usage events, so its battery is not spent on them. The phone reports five: first link, sign-in answered, Send to watch, playback moved, and changes merged from the watch.
