🎉 Phase 7: Polish & Documentation - FINAL PHASE

This PR completes the Developer Portal implementation with WorkManager testing functionality and comprehensive documentation. This is the final phase of the 7-phase development plan!

✨ Features Implemented

WorkManager Testing Card 🆕

Complete implementation replacing the previous placeholder:

• Real-time Work Status Monitoring

  • One-Time Work: Shows current state of debug test work requests
    • States: Not scheduled, ⏳ Enqueued, 🔄 Running, ✅ Succeeded, ❌ Failed, 🚫 Blocked, 🛑 Cancelled
  • Periodic Work: Shows status of scheduled periodic health checks
    • States: Not scheduled, ⏳ Scheduled, 🔄 Running
  • Uses WorkManager Flow observation for live updates

• Testing Controls

  • Trigger One-Time Check Button: Execute immediate health check without waiting
  • Integrates with existing sendOneTimeWorkRequest() function
  • Results visible in Alert Logs section
  • Snackbar feedback on trigger success/failure

• User Guidance

  • Info text explaining how to check results
  • Clear status indicators with emoji icons
  • Professional Material3 design matching other cards

🏗️ Technical Implementation

New State & Events

// State additions
val oneTimeWorkState: String?
val periodicWorkState: String?

// New event
data object TriggerOneTimeWork : Event()

WorkManager Integration

// Real-time observation in presenter
LaunchedEffect(Unit) {
    val workManager = WorkManager.getInstance(context)
    workManager.getWorkInfosForUniqueWorkFlow(DEVICE_VITALS_CHECKER_DEBUG_WORKER_ID)
        .collect { workInfos ->
            oneTimeWorkState = workInfos.firstOrNull()?.let { workInfo ->
                when (workInfo.state) {
                    WorkInfo.State.ENQUEUED -> "⏳ Enqueued"
                    WorkInfo.State.RUNNING -> "🔄 Running"
                    WorkInfo.State.SUCCEEDED -> "✅ Succeeded"
                    // ... other states
                }
            } ?: "Not scheduled"
        }
}

Event Handler

DeveloperPortalScreen.Event.TriggerOneTimeWork -> {
    scope.launch {
        try {
            sendOneTimeWorkRequest(context)
            simulationResult = "✓ One-time work request triggered"
            analytics.logScreenView(DeveloperPortalScreen::class)
        } catch (e: Exception) {
            simulationResult = "✗ Failed: ${e.message}"
        }
    }
}

🎨 UI Improvements

• Removed Placeholder Cards: Eliminated "🚧 Implementation in progress" and "Coming Soon" cards
