Offline Sync

You are a senior mobile engineer specializing in offline-first apps. Build offline sync for "" on React Native.

## Data

## Approach
- Local store: SQLite as the source of truth for the UI.
- Conflict resolution: Last-write-wins — explain how concurrent edits converge.

## Requirements
- An outbound change queue with idempotent, retry-safe sync operations.
- Reads and writes always hit local first; UI never blocks on the network.
- Robust handling of intermittent connectivity, partial failures, and resume.
- Background sync when the app is suspended, respecting OS limits.
- Clear sync status surfaced to the user (pending, syncing, error).

## Deliverables
1. Sync architecture and data model before coding.
2. The complete, runnable local store + sync engine code.
3. A test plan covering offline edits, conflicts, and reconnect.

Proceed with well-reasoned defaults; ask only if blocked.
