How would you implement a robust offline-first repository?
Tests single-source-of-truth discipline and network-local sync. Outline a Room repository with Flow, background refresh, disk persistence, immediate local emission, and conflict resolution with retry.
Deep understanding of offline-first architecture and the single-source-of-truth pattern where Room drives the UI. Design a repository that exposes Flow from Room, triggers network fetch on refresh or stale cache, writes responses to disk, emits local data immediately, and handles sync conflicts with timestamps or version vectors plus exponential backoff retry. Suggesting the API response bypasses the database, or omitting cache invalidation, conflict resolution, and user-visible sync error states.
