Hey @sunbiz , as the next task planned is preparing a week wise plan, so should I put my plan here in this thread?

Yes, and if you want to discuss in real-time, our chat is back up.

yes, thats a good idea. Please update it here, and if you want any quick decision related questions or troubleshooting, then chat is also fine.

  • Phase 1: Native Bridge & Android d2 Integration (Weeks 1 - 6)

    • Weeks 1-2: Spin up a local DHIS2 test instance via Docker, design the Pigeon communication schema, and implement native authentication (Login) end-to-end.

    • Weeks 3-4: Set up the d2 metadata sync module (org units, tracker programs) and map the 22-attribute Infant data model into a d2 TrackedEntityInstance.

    • Weeks 5-6: Sync clinical events (vitals histories, KMC sessions) and bundle them under their parent tracker enrollments. Run thorough integration tests.

    • Midterm Goal: A fully functioning Android d2 sync engine successfully pushing and pulling clinical data from a live DHIS2 playground!

  • Phase 2: Offline Queue & Sync UI Dashboards (Weeks 7 - 9)

    • Week 7: Build the Drift SQLite offline table schema and program the background SyncQueueManager to handle automatic retries and network listeners.

    • Week 8: Implement a server-wins conflict resolution handler (with a safe local visual log so nurses don’t lose custom details) and code the SyncBloc state machine.

    • Week 9: Build user-facing indicators: visual sync progress icons in the AppBar, status indicator dots next to patients on dashboard cards, and a new Sync Settings screen.

  • Phase 3: iOS Parity, Background Tasks & Final Polish (Weeks 10 - 12)

    • Week 10: Implement the iOS Swift service matching the Pigeon interface, calling standard DHIS2 tracker endpoints.

    • Week 11: Schedule periodic background tasks via Android WorkManager and iOS BGTaskScheduler to refresh data silently, optimized for cellular and battery constraints.

    • Week 12: Run final network degradation simulations (spotty/offline setups), complete the test suite, write developer documentation.

@sunbiz will this plan work or do i need to change anything it, and I will update here if there any changes in plan from my side.
