• Translation — On-device translation service
• VoiceTranscription — Voice-to-text transcription
• DataDetection — Automatic data detection in text
• SensorKit — Sensor data for burnout detection

Fixes (8)

• CalendarSync frequency capping
• DataDetection iOS 17+ fallback handling
• HKCharacteristicType reads hardened
• Voice auth guard added
• BurnoutDetector SensorKit deepening
• MessageThreadView DataDetection wiring
• Framework integration edge cases resolved

Severity Breakdown

• Critical (5) — Data integrity and crash fixes
• High (4) — Sync reliability improvements
• Medium (3) — UX and error handling
• Low (7) — Polish and edge cases

Code Fixes (3)

• APPLE-IOS-K — HealthKit physical effort unit crash (3 users, 6 events, fatal) — is(compatibleWith:) returns true for kcal/hr·kg vs appleEffortScore on some devices (Apple bug), but doubleValue(for:) then throws an uncatchable NSException. Added secondary unit description string check before calling doubleValue(for:).
• APPLE-IOS-M/S/1G — Blank screen on app switch (3 users) — checkAutoLock() was setting isLocked = true without withAnimation, so LockScreenView’s .transition(.opacity) never animated. Users saw a jarring blank overlay. Wrapped in withAnimation.
• APPLE-IOS-P — Settings arrow tap target (1 user) — .buttonStyle(.plain) on NavigationLinks limited hit area to visible content only. Added .contentShape(Rectangle()) to make full row tappable.

Triage Summary (52 Total)

• 47 resolved (3 code-fixed, 7 already fixed in prior rounds, 30 transient app hangs, 7 server/OS/old-build)
• 5 ignored (unlabeled events with no actionable data)
• 0 unresolved remaining

Critical Fixes

• FocusView timer bug — Added @Environment(\.scenePhase) + .onChange(of: scenePhase) handler. Without this, the timer didn’t recalculate from wall clock after backgrounding (FocusTogetherView had it, FocusView didn’t).
• ChatViewModel AI message ghost data — When messageRepo.createMessage() returns nil, the unsaved AI message was appended to UI but never persisted. Added SyncEngine enqueue fallback.

High & Medium Fixes

• MovementViewModel — logWorkout() catch block only logged to Sentry but didn’t set errorMessage. User saw optimistic success but sync failed silently.
• Focus session confetti — Wired .confettiCannon(trigger:) to FocusCelebrationRitual on session completion.
• Habit streak milestone toast — Added celebratedMilestone property + toast overlay with confetti for streaks [3, 5, 7, 10, 14, 21, 30, 60, 90, 100, 365].

Low Fixes

• Pull-to-refresh haptic — Added HapticManager.shared.trigger(.light) at end of .refreshable in PlanView, WellnessView, FocusView.

Widget Freshness (9 Operations)

• MedicationViewModel — Added WidgetCenter.shared.reloadAllTimelines() to: addMedication(), updateMedication(), takeMedication(), skipMedication(), removeMedication()
• WellnessViewModel — Added refreshWidgetData() calls to: createHabit(), incrementStreak(), updateHabit(), deactivateHabit()

Error Haptics (4 Catch Blocks)

• MedicationViewModel — Added .error haptic to addMedication(), takeMedication(), skipMedication() catch blocks
• WellnessViewModel — Added error message to user in incrementStreak() and updateHabit() catch blocks

UX Polish

• MessageThreadView — Empty state with bubble icon and “Say hello to start the conversation!” instead of blank scroll

Field-Aware Guest Migration (Data Integrity)

• OfflineStore.remapUserId() — Previously used blind replacingOccurrences(of:with:) which would rewrite the guest UUID anywhere in JSON — including conversation text or another user’s ID. Rewritten to decode JSON, walk the object tree, and only rewrite known userId field keys (user_id, userId, from_user_id, to_user_id, creator_id, owner_id).
• SyncEngine.remapUserId() — Same field-aware rewrite for both main queue and dead-letter queue.

Error Visibility & UX

• SyncEngine.refreshUpdatedAt() — Two try? calls silently returned stale data on JSON failure. Converted to do/catch with Sentry warning logs.
• WellnessView — Habits empty state enriched with leaf icon, heading, and “Tap the + above” subtext.
• JournalView — Added .refreshable for pull-to-refresh.
• AIHubView — Added .refreshable on message ScrollView.

Ghost Data Fixes (2 Critical)

• TaskRepository.createTasks() — Batch task creation saved locally, server insert fails → catch block logged to Sentry but did NOT enqueue to SyncEngine → all tasks vanish on next refresh. Fixed: added SyncEngine enqueue loop.
• TaskRepository.upsertTask() — Task upserted locally, server call had NO do/catch wrapper → failure throws without enqueue. Fixed: wrapped with SyncEngine enqueue.

Error Swallowing Fixes (2 High)

• ContactRepository.sendContactRequest() — try? JSONSerialization.data() could silently fail, creating nil payload that SyncEngine would dead-letter. Fixed: do/catch with Sentry logging.
• TaskRepository updateActualMinutes/updateEnergyCost — Server error path used try? encoder.encode(). Fixed: do/catch with SentryErrorTracker.captureEncodingError().

Widget Freshness (3 Gaps Closed)

• WellnessViewModel.refreshWidgetData() — Updated UserDefaults but never called WidgetCenter.shared.reloadAllTimelines(). Habit completions and mood logs didn’t update lock screen widgets. Fixed.
• HydrationService.syncToAppStorage() — Same pattern. Fixed: added widget timeline reload.

Toggle Haptic Feedback (3 Settings Views)

• NotificationSettingsView — 8+ notification toggles had no tactile feedback. Fixed: .sensoryFeedback(.selection, trigger:).
• CoachSettingsView — “Proactive Interventions” toggle. Fixed.
• EncryptionSettingsView — “Enable Encryption” toggle. Fixed.

Ghost Data Fix (1 Critical)

• TaskRepository.restoreTask() — User restores deleted task (undo), server call fails → no SyncEngine enqueue → restored task vanishes on next refresh. Fixed: added enqueue in catch block.

Race Condition Fixes (3 High)

• WellnessViewModel.completeHabit() — Between completedHabitIds.contains() guard and todayCompletions.append(), a second rapid tap could race through, causing duplicate XP awards. Fixed: atomic completingHabitIds Set with .insert().inserted guard.
• MedicationViewModel.takeMedication() — Same pattern — rapid taps could trigger double-dose logging. Fixed: atomic takingMedicationIds Set.
• FocusViewModel.scheduleTimer() — Timer loop while !Task.isCancelled didn’t check isActive, so stopTimer() could leave one extra tick. Fixed: added self.isActive guard.

Haptic Polish (4 Improvements)

• MainTabView — .selection haptic on tab change.
• PlanView — .medium haptic on swipe-delete task.
• JournalView — .medium haptic on swipe-delete journal entry.
• AIHubView — .medium haptic on swipe-delete conversation.

Ghost Data Fixes (6 Critical)

• CalorieService.addEntry() — Entry saved locally, server insert fails → catch block had no SyncEngine enqueue → entry vanishes on next refresh. Fixed: restructured scoping + added enqueue.
• CalorieService.addWeightEntry() — Same pattern. Weight entry saved locally, server failure → lost. Fixed.
• TaskRepository.updateActualMinutes() — Local cache updated, server update() had no try/catch → actual minutes revert on failure. Fixed: wrapped with SyncEngine fallback.
• TaskRepository.updateEnergyCost() — Same pattern. Energy cost label reverts on server failure. Fixed.
• SharedGoalRepository.archiveGoal() — Server call with no catch → archive status lost on failure. Fixed: optimistic local update + catch with enqueue.
• SharedGoalRepository.deleteGoal() — Server delete with no catch → goal deletion lost on failure. Fixed: optimistic + enqueue.

UX Hardening

• AddTaskSheet — Added .interactiveDismissDisabled(currentStep > 0) so users can’t accidentally lose 9 steps of task creation by swiping down mid-wizard.
• TaskViewModel — Widget staleness eliminated: added WidgetCenter.shared.reloadAllTimelines() after task create, complete, and delete.
• PlanEmptyState — Scale + opacity + offset entrance animation (hero icon 0.6→1.0, text slides up). Respects shouldReduceMotion().
• OnboardingView — Added .light haptic to skip button.

How It Works

• Guest taps “Create Account” in Settings → AppState.upgradeGuestToAccount() saves the guest UUID, clears guest mode, shows AuthView
• User signs up → .signedIn fires → detects pendingGuestMigrationId
• OfflineStore.remapUserId(from:to:) rewrites all cached JSON files, replacing local guest UUID with new server UUID (handles encryption transparently)
• SyncEngine.remapUserId(from:to:) rewrites all queued payloads and dead-lettered changes
• SyncEngine triggers immediate syncPendingChanges() — all guest data uploads to Supabase under the new account

Key Design Decisions

• UUID replacement at raw JSON level — handles all 20+ entity types uniformly without per-type decode/re-encode
• Dead letter queue also remapped — no data left behind
• Settings shows “Create Account” card only when isGuestMode is true; Delete Account hidden for guests

Redesigned Architecture

• enterGuestMode() generates persistent local UUID, calls resolveUserId() so all ViewModels get the guest UUID instantly, sets appMode = .local
• restoreGuestModeIfNeeded() restores guest mode on cold launch from UserDefaults, skips observeAuthChanges() entirely
• signOut() updated: skips push token deactivation and Supabase sign-out for guests
• Data flow: ViewModels call awaitUserId() → local UUID → repos try server → fail → OfflineStore fallback. No push, no realtime, no JWT refresh

Onboarding Enhancements

• Animated icon entrance per page: icons scale from 0.5 → 1.0 with bouncy spring + fade in
• Staggered title/subtitle entrance: slide up from 20pt offset with 0.15s/0.25s/0.3s delays
• Welcome page: app logo gets .glowPulse() effect + gentle floating animation (±4pt, 3s cycle)
• Animated page indicator: current page shows wider capsule (20pt) with spring transition
• Assessment cards: scale to 1.02x on selection; checkmark icons use .contentTransition(.symbolEffect(.replace))
• All animations gated behind shouldReduceMotion() for accessibility

Confetti Celebration System (New)

• ConfettiCanvasView using TimelineView(.animation) + Canvas for 60fps rendering
• 50–80 particles with random shapes, colors, rotation, spin, drift — auto-clear after 2.5s
• Reduced motion fallback: brief opacity flash instead of particles
• Reusable .confettiCannon(trigger:) ViewModifier

Level-Up & Task Completion Polish

• RewardBadge: confetti on level-up, card scale-in with bouncy spring, emoji pulse, streak haptic
• PlanView: checkmark bounces on completion, circle fill animates, haptic upgraded to Core Haptics pattern
• HabitTrackingView: checkbox icon bounces on completion

Missing Replay Handlers Added

• focus_session/update — Duration updates made offline were silently dropped
• conversation/update — Conversation metadata updates dropped
• message/soft_delete — Deleted messages never soft-deleted on server, would reappear on next sync
• contact/send_request — Contact requests sent offline were lost. Also fixed ContactRepository to include from/to/message in enqueue payload (was nil before)
• contact/accept_request — Accepted requests offline were lost
• contact/reject_request — Rejected requests offline were lost
• contact/update_tags — Tag updates offline were lost

Additional Fixes

• All default: cases now log to Sentry instead of silently breaking — future unhandled actions caught immediately
• MovementTrackingView.formattedSteps — NumberFormatter() was created on every render. Cached as static let stepsFormatter (expensive init: locale, calendar, number system)

Ghost Data (G1)

• MessageRepository.createMessage() — When online and server insert failed, the error propagated without enqueuing to SyncEngine. Message was saved locally but would never sync. Fixed: wrapped server call in do/catch, enqueue encrypted payload on failure, return local copy so UI isn’t broken.

Crash Risk (C1)

• RewardBadge.swift — Force unwrap rewardService.nextLevel!.title in accessibility label, guarded only by a ternary != nil check. If the value changed between check and access (e.g., concurrent state update), this would crash. Fixed: replaced with if let optional binding.

UX Gaps (U1–U2)

• SleepRoutineView — Missing .refreshable. Users couldn’t retry a failed load of sleep routines and alarms. Fixed: added .refreshable { await viewModel.loadAll(forceReload: true) }.
• MovementTrackingView — Missing .refreshable. Same gap for workout history. Fixed: added .refreshable { await movementVM.loadAll() }.

Ghost Data (G1)

• TaskRepository.deleteTask() — When online, if the server soft-delete call failed, the error propagated without enqueuing to SyncEngine. Task was deleted locally but not on server — would reappear on next refresh. Fixed: wrapped server call in do/catch, enqueue on failure + Sentry capture.

UX Gaps (U1–U2)

• ConversationListView — Missing .refreshable. Users couldn’t retry a failed conversation load without navigating away. Fixed.
• ConversationListView — Missing .alert() wired to viewModel.errorMessage. Load failures were silently swallowed with no user feedback. Fixed.

Accessibility (A1–A2)

• AIHubView — “New Chat” button had .accessibilityIdentifier for testing but no .accessibilityLabel for VoiceOver. Fixed: added .accessibilityLabel("New chat").
• AIHubView — “Chat History” button same issue. Fixed: added .accessibilityLabel("Chat history").

Ghost Data (G1–G3)

• HydrationService.deleteEntry() — When online and server delete fails, entry was deleted locally but NOT enqueued to SyncEngine for retry. Entry would reappear on next server refresh. Fixed: added SyncEngine.shared.enqueue(...) in the catch block.
• CalorieService.deleteEntry() — Identical pattern. Calorie entries deleted locally could reappear after failed server delete. Fixed.
• CalorieService.deleteWeightEntry() — Same pattern for weight entries. Fixed.

UX Gaps (U1–U2)

• HydrationTrackingView — Missing .refreshable. If initial load failed, user had no way to retry without switching tabs. Fixed: added .refreshable { await hydrationService.loadToday() }.
• FocusViewModel.stopTimer() — After a focus session ended, WidgetCenter.shared.reloadAllTimelines() was never called. Focus widget could show stale data until next automatic refresh. Fixed: added widget reload after session sync.

APPLE-IOS-4 — HTTP 401 on /rest/v1/tasks (801 events, 71 users)

• Root cause: When the app is suspended for hours, the Supabase SDK’s internal JWT refresh timer doesn’t fire. On resume, the stale token causes 401s on every API call until the SDK eventually refreshes.
• Fix: Added SupabaseService.refreshSessionIfNeeded() that proactively refreshes the JWT on every foreground return (called from ConvoActApp’s .onChange(of: scenePhase) handler). Skips refresh if the token has >1 minute of validity remaining.

APPLE-IOS-C — evaluateOnLaunch errors (3,488 events, 101 users)

• Root cause: The 5-second timeout safety gate in DailyAdaptiveService.evaluateOnLaunch() was capturing every timeout as a full Sentry error event. These timeouts are expected behavior (network not ready at app launch) and the code correctly falls back to cached data.
• Fix: Downgraded URLError(.timedOut) to .info-level breadcrumb; real failures still captured as errors.

APPLE-IOS-B/1W/1X — App Hangs (2000ms threshold)

• System-level hangs in SwiftUI type resolution, dylib loading, and Swift metadata. All single-occurrence, 1 user each.
• Fix: Moved SentrySDK.start() off main thread to reduce main-thread pressure at launch. Marked resolved — will auto-reopen if they recur.

Data Integrity (D1–D5)

• OfflineStore.swift — Fixed read-modify-write race in softDeleteTask(), restoreTask(), purgeOldDeletedTasks() by operating on tasksCache directly instead of load→modify→save
• SyncEngine.swift — Made dead-letter retry transactional: build re-enqueue list first, enqueue all, then clear dead letters (prevents data loss on partial failure)
• ContactRepository.swift — Added SyncEngine enqueue on server failure for sendContactRequest(), acceptRequest(), rejectRequest()
• WellnessViewModel.swift — Added checkDayRollover() method comparing current day to lastLoadDay, forces reload when date changes
• WellnessView.swift — Added scenePhase observer to trigger day rollover on foreground return

UX Reliability (U1–U8)

• SleepRoutineView — Replaced inline error text with proper .alert() modifier
• MovementTrackingView — Added .alert() for movementVM.errorMessage
• FocusView — Added .alert() for sharedGoalViewModel.errorMessage
• MainTabView — Added throttled (5-minute cooldown) medication/habit/hydration refresh on .active scenePhase via DataRefreshBus
• MedicationVM, CycleVM, WellnessVM — Added offline feedback: “Saved offline — will sync when connected”

5-Star Polish (P1–P8)

• AddTaskSheet — Added .scrollDismissesKeyboard(.interactively) and minHeight: 56 for Dynamic Type
• HabitTrackingView — Added VoiceOver .accessibilityAction(named:) for Complete, Edit, Delete
• FocusReadinessDetailView — Added text labels (“Excellent”, “Good”, “Fair”, “Low”) next to color indicators per WCAG
• PlanView, ConversationListView — Changed .lineLimit(1) to .lineLimit(2) on titles
• AccessibilitySettingsView, SettingsView — Added .sensoryFeedback(.selection, trigger:) to toggle helpers
• MessageThreadView — Added .refreshable { await loadMessages() }

Repository Layer — SyncEngine Fallback on Server Failure

• HydrationService.addEntry() — Online server insert failure now enqueues to SyncEngine for retry (was throwing without fallback, creating ghost hydration entries)
• SharedGoalRepository.createGoal() — Multi-step server operation now catches failures at any step and enqueues the full payload for deferred sync
• SharedGoalRepository.updateProgress() — Online failure now enqueues progress update for retry
• MessageRepository.deleteMessage() — Online soft-delete failure now falls back to local soft-delete + SyncEngine enqueue
• ContactRepository.updateTags() — Both offline and online-failure paths now enqueue for retry

Repository Layer — Encoding Error Capture

• SleepLogRepository createLog() / updateLog() — try? encoding replaced with do/catch + SentryErrorTracker.captureEncodingError()
• SleepRoutineRepository createRoutine() / updateRoutine() — Same fix
• WorkoutLogRepository createLog() — Same fix

ViewModel Layer — try? → do/catch + Sentry (18 methods)

• TaskViewModel — createTask, createTasksBatch, updateTask, toggleComplete, restoreDeletedTask
• MedicationViewModel — addMedication, updateMedication
• WellnessViewModel — logMood, createHabit, completeHabit, incrementStreak, updateHabit
• CycleViewModel — logToday (update + create paths), updateSettings
• SleepRoutineViewModel — addRoutine, updateRoutine, logSleep
• MovementViewModel — logWorkout
• ChatViewModel — startNewConversation
• MessagingViewModel — createDirectConversation
• FocusViewModel — endSession, createSession
• SharedGoalViewModel — createGoal

Destructive Ops with User Feedback on Failure (5 methods)

• WellnessViewModel.deactivateHabit() — Added do/catch + Sentry + errorMessage
• SleepRoutineViewModel.removeRoutine() — Same
• SleepRoutineViewModel.deleteSleepLog() — Same
• MovementViewModel.deleteWorkout() — Same
• SharedGoalViewModel.archiveGoal() — Added errorMessage

Views

• SettingsView.deleteAccount() — Bulk try? per-table deletion replaced with individual do/catch per table, each logging to Sentry with table name (prevents silent partial account deletion / PII retention)

Subscription (Round 2)

• Purchase button now uses selectedPlan.productId instead of hardcoded monthly ID
• Restore purchases shows success/failure feedback
• .unverified purchases logged to Sentry

Habit & Wellness (Round 2)

• Added completedHabitIds double-tap guard
• Added lastLoadDay for midnight boundary staleness detection
• Atomic habit reminder rescheduling (schedule new first, then remove stale)

Task Management (Round 3)

• TaskRepository.updateTask() — Changed from online-only enqueue to always-enqueue pattern
• Added togglingIds Set to prevent rapid double-tap flip-flopping
• SyncEngine now has hasPendingChanges(for:); background refresh skipped when local changes pending

Focus Sessions (Round 3)

• Added guard !isActive to prevent duplicate sessions
• Only counts completed sessions (not abandoned) for stats
• Added cumulativeWorkSeconds for accurate Pomodoro duration
• Fixed Live Activity race condition: currentActivity = nil before async end Task

Medication (Round 3)

• Added takenTodayIds double-dose guard
• Background sync changed from try? to do/catch with error feedback

Messaging (Round 3)

• Full unread tracking via UserDefaults lastSeenKey timestamps
• Wired markConversationRead on thread open
• Realtime messages inserted in chronological order; isSending set before awaits

Auth & Encryption (Round 3)

• AppState.signOut() now calls EncryptionService.shared.deleteKey() to prevent cross-user key leakage
• Encryption toggle now shows confirmation alert with migration warning

SKStoreReviewController Integration

• New ReviewPromptService.swift — @MainActor singleton tracking milestones
• Prompt conditions: 5+ focus sessions OR 10+ tasks OR 7-day streak, 14+ days since install, 90+ days since last prompt, new app version
• Trigger points: RewardService.award() (level-up), FocusViewModel (session dismiss), WellnessViewModel (streak milestones at 7, 30, 100 days)

Test Concurrency Fixes

• BurnoutDetectorTests.swift — Converted to override func setUp() async throws with MainActor.run {}
• ChatViewModelTests.swift — Same pattern for mock init/teardown
• FocusViewModelTests.swift — Same pattern for mock init/teardown
